The invention relates to a handheld tool that can be used in rescue operations during emergencies.

A well-known tool for rescue work produced by the firm “LU-KAS” (Germany). For each type of work is used CTD functionality of each type of instrument, consequently for carrying out various operations in the rescue operations require multiple tool types, which complicates its transportation and increases the duration and cost of rescue operations.

Known technical solution according to the patent of Russian Federation № 1814596, CL 23 D 29/00, which is the closest to the technical nature of the proposed technical solution. This patent provides a hydraulic drive, comprising a housing placed in it a piston, a removable actuator, comprising a housing for the end of the tabs, and the items connected to the housing of the hydraulic actuator by means of a bayonet clip and screw connections, clamp connections, made in the form of limiter (protrusion) at the end of the holder operating mechanism and limiter (ledge), performed on the shroud. Removable actuating mechanism is in the form of pliers, scissors, rassimov.

The disadvantage of this technical solution is the implementation of latch in the form of two tabs, as this version release is possible only in one fixed position, which is very inconvenient when carrying out rescue operations, when cotorreando). Given that according to the invention, the tool does not have a standalone drive, and the pump module is in each case connected to the hydraulic system, including hoses, couplings and pump, it is impossible to turn in different directions, and hence the tool can only work in one direction. All this creates inconvenience when working in emergency situations. In addition, the complex is connecting and disconnecting removable actuator to the hydraulic actuator in connection with the necessity of unscrewing and screwing into the body of the hydraulic transmission node, in addition to connecting the removable actuator with yoke and the housing of the hydraulic drive.

The technical object of the present invention is to improve the mobility tool, ease of use and reduction of time for rescue work.

The problem is solved in that in the multi-function hydraulic tool containing a hydraulic actuator, consisting of a body and placed in it a piston, a removable actuator including a housing and work items, the latch removable connection mechanism to the housing of the hydraulic actuator, and the mating ends of the specified block is n spring-loaded rod, one end connected to the working element of the actuator, and the second is coupled with a piston of the hydraulic actuator, with each radial protrusion of the housing of the actuator is made a groove, and the latch connection of the housing of the hydraulic actuator and the actuator is made in the form of a spring-loaded pawl mounted on the end of the housing of the hydraulic actuator associated with the housing of the actuator and the locking dog made treasurey (retainer, thrust and Rethimno teeth) with the possibility of installing the locking tooth when you commit in a groove made on the housing of the hydraulic drive and to one of the four grooves made in the notches of the housing of the actuator, moreover, the housing of the hydraulic actuator is rigidly connected with the pump module.

The proposed set of features is new, as it has distinctive properties from the prototype, and thus the proposed solution meets the criterion of “novelty”.

Due to the implementation of the transfer node in the form of a rod with a return spring and having a groove in each of the four radial protrusions when connecting the actuator with the hydraulic drive, one of the grooves to be installed opposite the groove, wygb spring-loaded pawl is automatically installed in these slots. This eliminates the possibility of the tool, if the connection has not been until the end. If necessary, reposition the tool enough to bend Rethimno tooth pawl and rotate the actuator to match the other groove in the radial protrusion of the actuator with the groove of the housing of the hydraulic drive and when releasing the camshaft tooth locking tooth is automatically installed in both slot and the tool is ready to work in the new position. In addition, execution of the transfer node in the form of a rod with recoil spring in conjunction with the new design of the locking element allows quick replacement of one type of actuator to another, which is very important when working in emergency situations. It is enough to press the dog, remove the actuator, to install another tool, lower the presser tooth pawl and the instrument is ready for operation. Rigid attachment of the pump module to the hydraulic drive eliminates hoses and holding the pump in the same position when replacing the actuator or change its position.

A new mechanism of action of the elements collectively significant is the way, the claimed technical solution meets the criterion of “inventive step”

The proposed design is illustrated in the drawings, where Fig 1 shows a General view of the instrument; Fig 2 is a view along section a-a of Fig.3 is a view along section b-B of Fig.4, 5 - Executive mechanisms.

The instrument contains the pumping module 1 comprising a body 2, placed in it a two-stage plunger 3, the associated valve system with channels of low and high pressure (not shown) and rigidly connected with the hydraulic actuator 4, consisting of a body 5, is placed in the housing of the piston 6 with the return spring 7 and replaceable actuators: scissors 8, unclamping small 9, unclamping the big 10, the unclamping special (angular) 11, the cutter 12. Each of the actuators includes work items 13, case 14 with the installed push rod 15, the return spring 16. At the end of the housing 14, opposite to the Executive elements, a radial protrusions 17, 18, 19, 20 and grooves 21. Each radial protrusion 17-20 along the Central axis is made a groove 22, 23, 24, 25. On the housing 5 of the hydraulic actuator 4 on the inner surface of the executed response grooves 26, the protrusions 27 and beyond the annular groove 28, and the outer surface of kreplenie on the axis 30 of the dog 31, spring-loaded by a spring 32. The dog 31 is made treasurey: locking tooth 33, stubborn 34, Rethimno 35. To the housing 2 of the pump module 1 is fixed arm 36, resulting in the movement of the plunger 3, and the handle 37.

In the body of the handle 37 posted by elastic capacity 38 for hydraulic fluid injected into the piston cavity of the hydraulic drive 4.

The tool is as follows.

The end of the actuator with the radial projections 17, for example scissors, 8, install in the housing 5 of the hydraulic actuator 4, combining radial projections 17 with slots 26 to the passage of the radial projections 17 in the annular groove 28. The locking tooth 33 of the pawl 31, the pressing Rethimno tooth 34 is in the raised position, with hard tooth 35 rests on the housing 5. After placing the radial protrusions 17-20 in the annular groove 28 of the locking tooth 33 is lowered into the groove 26, releasing Rethimno tooth 35, and run the actuator until sticky tooth 33 in one of the slots 22-25 one of the radial protrusions 19-22. Thus there is a reliable fixation of the actuator in the hydraulic actuator 6. Next, the tool is fed to the actuator in the required work area of the tool, and the swing arm 36 of the pump module 1 notrim is closer to the cutting edge of the working element 13, scissors 8. A further increase in pressure leads to the exposure of the cutting edges on the cutting material, cutting it. After cutting the discharged pressure, and the piston rod 15 under the influence of return spring 16 returns to its original position with work items 13. If there is a necessity of changing the position of the tool to perform the operation of cutting or unclamping, for example, you must change the angle of the actuator, in this case, without removing the actuator from the housing 5 of the hydraulic actuator 4, push camshaft tooth 35 of the raised locking tooth 33 of the slots 29 and 22, the rotatable actuator 8, omit razgonnyj tooth 35 and the locking tooth 33 gets into the groove 29, and continue to rotate the actuator to sticky the locking tooth 33 in the groove 23 or 24 of the next radial protrusion, for example 18 or 19. The instrument is ready for operation. To change the position of the actuator is required not more than 10 C. Replacement of one actuator to another do the following. Click Rethimno tooth 35, raise the locking tooth 33, remove the actuator, for example scissors 8, the body 5 of the hydraulic actuator 4 and install as described in the s (not shown) and the handle 36 of the pressurizing hydraulic fluid in the piston cavity of the hydraulic actuator 4, when the piston 6 moves the rod 15, which pushes the work items and lifts the plate. The time of replacement of one form of the actuator to the other is not more than 20-25 C.

Thus, the present invention when operating in emergency situations allows quick replacement of one actuator to another, to work in any position of the actuator, which is very important, as it allows to reduce the time required to prepare the instrument for use, and therefore reduce the overall time of the operation (unclamping, cutting, lifting, and so on).
