The invention relates to mechanical engineering and can be used to prevent unauthorized movement of machines and mechanisms, the construction of which is applied a telescopic supporting outriggers. In particular, the construction of locking devices (commit) telescopic support (outrigger) self-propelled construction machine.

Known for a large number of analogues of the invention implemented in designs support-rotating devices craniomandibular installations, cranes and various specialized lifting vehicles both domestic and foreign developments (SU # 370160, B66C 23/88, 15.11.1973,, GB No. 1465289, B60S 9/10, 02.03.1977,, GB No. 1467128, B60S 9/10, 16.03.1977,, GB No. 1496291, B60S 9/00, 9/12, 9/22, 30.12.1997,, JP No. 58-44495, B60S 9/12, 04.10.1983,, JP No. 1-195162, B60S 9/12, B66C 23/78, 07.08.1989 year).

In most of these analogues remote outriggers hinged or rigidly fixed at the ends of the retractable from the body frame to the Foundation beams. When this extension beams (removal outriggers) is carried out usually by means of specially provided for this cylinder.

However, many of them are complex in design and have a large mass. Moreover, because of the presence of Autonomous drive movement of the beams on the basis of the cylinders in such a remote outriggers require the tsya organization additional hydraulic control channels. But, despite this, for many lifting transport vehicles, primarily heavy class used in the above analogues technical solutions in General justified.

For craniomandibular installations easy and in some cases middle class, placed on the chassis of vehicles needed in the hydraulic actuators, providing a take-out outriggers, virtually no, because the extension beams attached to them outriggers can be implemented manually. At the same time to provide normalized values attached to the manual effort required to nominate beams, in some cases, take special measures, for example, associated with relief of moving parts, reducing friction in the movable joints, and other Such external outriggers much simpler in design and cheaper in terms of value, compared with the known above counterparts.

In addition, construction of the extension of the outriggers of this kind due to the nature of their execution, as a rule, provide for appropriate mechanisms commit nominated beams in the extreme positions.

So famous outrigger outrigger, mainly hydraulic craniomandibular installations placed on the chassis of the vehicle that contains a basic frame with a fixed hollow beam, within which time esena manually retractable beam mounted on it with an outrigger, and located on the side wall of the stationary beams off the transom clamp-type locking retractable beams in the extreme positions it on the side of the cantilever part retractable beams in an area where the clamp is rigidly fixed mechanical pusher with profiled Cam, kinematically interacting with the sliding movement of the beam with the handle of the swivel lock lever when extracted out of engagement with the specified beam cross-bar (RU # 2175947, B66C 23/78, B60 S9/02, publ. 20.11.2001,).

The disadvantage of this solution is that the pins and the blockers are used to hold the outrigger or in the frame of the construction machine in the transport position, or when Pirani on the ground in the working position of the outriggers, these blockers fix the position of the parts of the outrigger or the outrigger relative to the frame of the construction machine for positioning an outrigger in a defined position for transport or working while resting the heel on the ground. These latches or interlocks are, as a rule, manual controls, inputting the locking element or its withdrawal from the zone of interaction with parts of the outrigger. Such latches or interlocks are not secure and can be powered by an outside individual. As such blockers and tabs not usmatrivayutsya as systems against theft of the construction machine.

The present invention is directed to the achievement of the technical result consists in preventing inadvertent or unauthorized movement of construction machinery due to its fixation relative to the surface using a mechanical lock made in the working position of the telescopic leg - (outrigger).

This technical result is achieved by setting (welding) on the stationary part of the telescopic support device that allows a mechanical way to put the finger in the aligned holes of the movable and fixed parts of the telescopic leg (outrigger), thereby blocking the ability of folding support in the transport position.

While this result is achieved in that the locking device telescopic support (outrigger) construction machinery, representing steel finger entered in the transverse direction through aligned holes in the outer and inner pipes support (outrigger), supplied welded to the outer pipe support (outrigger) a housing with a through round hole having a vertical plane of the groove terminating in the circular groove, and steel toe with cross pin to fit through the round hole of the housing in the vertical orientation of the shaft with the focus ring of the second groove and the introduction of the other end through the holes in the outer and inner tubes of the telescopic leg, at the other end of the steel finger mounted lock "washer" to commit the specified finger against rotation relative to the housing in the horizontal position of the shaft with the bearing in an annular groove at the expense of the lock tab lock washer" in the case.

In addition, this result is achieved by way of protection against theft of the construction machine, having a telescopic leg (outriggers), characterized by the fact that the construction machine is lifted above the support surface on telescopic supports, and then in one or all of telescopic supports (outriggers) provide a mechanical lock of the inner and outer pipes at the expense of putting in the transverse direction through aligned holes in these pipes, steel toe, fixed against axial movement locking mechanism.

These characteristics are essential and interrelated with the formation of a stable set of essential features, sufficient to obtain the desired technical result.

The present invention is illustrated with a specific example of implementation, which, however, is not only possible, but clearly demonstrates the possibility of achieving the desired technical result.
