Thrust 4 is connected with a power ring with swivel bearing 12. In bearings 10 and 11 with the possibility of radial movement established the trunnions 13 and 14, on which hinged the drum 15. Each pin is made with the heel "and"interacting with the response, the fifth spherical of 16, mounted on the TBM. The drum 15 includes an outer 17 and 18 internal shell, the space between which is overlapped with the end elements 19 and 20, which are evenly along the circumference about the longitudinal axis of the drum, which is geometrically aligned with the longitudinal axis 5 of the shaft structure, respectively installed radial lugs 21, which interacts with the corresponding response elements 22 and 23 of the transport and launch container 1. Radial lugs 21 allow "post" lateral loads on the building of the WPK. Stops 21, which interacts with the element 23, passed through the power ring 9 without contact with the latter. Thus, due to the particular structural embodiment of the drum 15 "unleashed" relative to the force ring 9 and does not perceive vertical load.

System vertical cushioning as shock absorbers 6 contains pnevmoapparatury. Through the use of pnevmoaeratorov due to the change in the value of the pressure in pneumohemothorax ensures the adaptability of the system depreciation to depreciable objects of different mass and temperature change inside the mine facilities. The plunger 24 of each pneumohemothorax 6 is in contact with the corresponding arm 25, which has one end fixed on the wall of the shaft structure 2 can be rotated in a vertical plane, and the other is connected with a corresponding thrust 4. In the embodiment of the invention, the rocker 25 is made in the form of a cross with a shrug "b" and "C". Shoulder "b" crosses pivotally connected with the rod 26 of a hydraulic damper 27, the casing of which is hinged to the corresponding stationary base (7 or 8). This design reduces the moves on the shock absorber (pneumonocyte) 6 and a step change of the elastic force characteristics of the shock absorber, which allows to obtain a stable position of depreciable object vertically to change its mass and temperature in the mine construction. Pneumoactuator 6 is made to lock in a compressed state (e.g., in the absence of a TPK or unloaded TLC) using the folding element 28, which is pivotally attached to a stationary base (respectively 7 or 8) with detachable connections with the shoulder "with the appropriate crosses (i.e. beam) 25. Free (tilted) position, the element 28 is fixed on the bracket (not shown)mounted on the wall of the shaft structure 2.

Si is theme of the horizontal depreciation includes upper and lower tiers of depreciation, each of which contains a shock-absorbing devices 29 and 30, which with appropriate embedded parts 31 and 32 mounted on the wall of the shaft structure 2 and a lever mechanisms rods 33 34 kinematically connected with TLC 1 using the appropriate adapter 35. In the embodiment of the invention, the adapter 35 cushioning devices 29 and 30 of the lower tier horizontal depreciation associated with TLC 1 through the annular element (adapter ring) 36, which is located on the side of the lower end of the WPK and Rethimno connected with the latter by means of brackets 37 with the pin 38. In the plan (i.e. in the top view) shock absorbing devices 29 and 30 of each layer form two spaced opposite pairs. Shock absorbing devices of each pair are located near the vertical plane of 39 passing through the longitudinal axis 5 of the shaft structure and located orthogonal to the plane 40, which are thrust 4. Thrust 34 of each of these pairs of shock-absorbing devices are placed crosswise. This arrangement cushioning system devices horizontal depreciation increases the compactness and simplifies maintenance. In addition, this arrangement minimizes overlap the annular space between the TLC and the wall of the shaft that is used to drain the gas jet when starting the engine of a rocket at gasdynamic type of start. In the embodiment of the invention shock-absorbing devices 29 and 30 of the system of horizontal depreciation include, each, a vertically mounted hydraulic damper 41 with zero-installer 42.

Hydraulic dampers 27 system vertical depreciation and hydraulic dampers 41 system horizontal depreciation provided with each device 43 fixing the position performed with electric control. The device 43 of the fixing, in essence, is a locking mechanism that ensures the overlapping channel for flowing fluid from one cavity of the hydraulic damper to another. Thanks to the device 43 is provided pinning RIC in a certain position relative to the shaft structure (for example, before the start of TPK).

Thrust 4 system vertical cushioning and traction 34 system horizontal depreciation is made adjustable in length. In the embodiment of the invention the support device 3 system vertical depreciation is located between the upper and lower tiers of the system horizontal depreciation, which, in turn, installed height, respectively, above and below the center of mass of depreciable object (i.e. TPK).

Device for depreciation of the transport and launch container in mine construction works as clicks the zoom.

At the place of installation of the device is delivered in the form of separate units, which are secured in mine construction in locations pre-installed embedded parts (stationary bases) 7, 8, 31 and 32. In the embodiment of the invention, first of mounting the shock absorbing devices 29 and 30 of the upper and lower tiers of the system of horizontal depreciation. Then mounting the support device 3, and then mount system equipment vertical amortization.

TLC is set as follows.

First transport-launch container 1 through mounted diametrically opposite on the side of the case TPK (i.e. is located in the center plane LC) two spherical toe 16 is installed in the return thrust "and" pins 13 and 14 that are installed with the possibility of radial movement in the bearings 10 and 11, mounted on the power ring 9. The position of the TBM relative power of the ring 9 in the transverse plane is fixed by means of radial lugs 21 mounted on the end elements 19 and 20 of the drum 15. Thus, TPK with the control device 3 to form a single structure, which through the power of the ring 9 is suspended on a pendulum rods 4. While TPK 1 with the drum 15 is pivotally connected with a power ring 9 can be rotated otnositel the two mutually orthogonal axes. One of these axes geometrically coincident with the common longitudinal axis of the pivots 13 and 14, on which hinged the drum 15, and the other passes through the centers of the swivel bearing 12 through which thrust 4 is connected with a power ring 9 support device 3. Thus, in a pendulum suspension implements connection, called the universal hinge or hinge gook. As an intermediate universal joint includes a power ring 9.

After TLC are combined with a system of horizontal depreciation. On lateral surfaces of the enclosure TPK 1 and is mounted on TLC annular element 36 through the adapter 35 with threaded connections (not shown) is fixed thrust 34 of the upper and lower tiers of the system of horizontal depreciation. Thus, from the transverse displacements of the WPK held by means of four rods 34 cushioning devices 29 and 30 of the upper tier system horizontal depreciation, fixed directly on the housing of the WPK, and four rods 34 cushioning devices 29 and 30 of the lower tier system horizontal depreciation fixed on United with case RIC annular element 36.

In this form of the TBM can be in mine construction, not requiring maintenance.

Device for depreciation of the transport and launch container in mine is okrujenii works in two modes:

in the standard mode of operation (i.e. in the regime of depreciation TPK);

- commit mode TPK in a certain position relative to the shaft structure (for example, before the start of TPK).

In the first case with seismic effects is quite complex vertical and horizontal in any direction moving shaft constructions involving vertical and horizontal accelerations. The present invention provides the possibility of relative movement of the WPK (depreciable) and mine facilities and minimizing the loading of the party. While TPK 1, secured to the support device 3, hanging on the rods 4 system vertical amortization, and held two tiers rods 34 system horizontal depreciation, oscillates (bobs) from top to bottom due to the operation of the system vertical amortization, and pendulum swings in a vertical plane and transverse vibrations due to the operation of the system horizontal depreciation. In the plane 39 orthogonal to the plane 40, which are thrust 4, TPK 1 together with the drum 15 and the power ring 9 wobbles due to the swivel bearing 12, which is provided with thrust 4. Making vibrations in the plane of the rods 40 of the vertical system of depreciation, TPK 1 drum 15 as a whole has perhaps the th swinging on the pivots 13 and 14 relative to the force ring 9, keeping its vertical position. Thus, when a trapezoidal suspension rods 4 in the plane of the rods allows the swinging angle of the power ring 9 relative to the drum 15 with TLC 1. This allows for horizontal movement of the WPK (depreciable object) to eliminate the effect of system devices vertical depreciation on system performance horizontal depreciation and, ultimately, increases the reliability of the device amortization.

At the end of the perturbation (seismic) effects TPK due to the pendulum suspension under the influence of the pendulum point returns to its original position. Hydraulic dampers 27 and 41 systems respectively vertical and horizontal depreciation accelerate the damping TPK (depreciable property). Zero-installers 42 provide the reset system horizontal depreciation.

Thus, the suspension of depreciable object on two pendulum rods with two layers (zones) horizontal depreciation provides for the operation of the vertical and horizontal depreciation vertical position (stability) depreciable object for horizontal panning and tilting of structures, and also provides the ability to use to return depreciable object in ishomepage on the horizon (i.e. - in the horizontal plane) of the pendulum of time, providing resistance TPK in a vertical position.

Mode of fixation of the WPK in a certain position relative to the shaft structure TPK is fixed by switching devices 43 fixing the position, which is provided with hydraulic dampers 27 and 41 systems vertical and horizontal cushioning. If this is blocked the flow of working fluid from one cavity of the hydraulic damper in the other.

Thus, due to the peculiarities of the device for depreciation TPK in mine construction, in particular, especially the performance of the reference device pendulum trapezoidal suspension system, vertical amortization, the invention provides increased reliability of operation of the device of depreciation. Together with this, the proposed device provides adaptability to depreciable objects of different mass and temperature change inside the mine construction that extends the functionality. In addition, the invention improves the compactness and ease (to simplify) the maintenance depreciation.
