(54) DEVICE FOR FIXING REMOTE SUPPORT OF A VEHICLE

one

The invention relates to vehicles in which it is necessary to eliminate the influence of the chassis suspension in the operation process by hanging the chassis on the jacks.

A device for fixing vehicle outriggers is known, comprising a crank mechanism, a ram and a hinge bracket pivotally mounted on the vehicle frame and rigidly connected to the body of the outrigger support and stops mounted on the vehicle frame 1.

However, the known device is not sufficiently reliable in operation due to non-simultaneous withdrawal of supports.

The aim of the invention is to improve operational reliability by simultaneously withdrawing two outriggers from opposite sides of the vehicle.

The goal is achieved by the fact that the device is equipped with a three-arm lever mounted on the vehicle frame and connected to the ram, single-arm levers fixed to the cranks of the crank-connecting rod mechanism of each outrigger support, and barbells whose ends are hinged to

a three-arm with a lever, while others are also articulated with a single-arm with a lever of the corresponding outrigger, and the stops are made with a conical surface in contact with the cranks of the corresponding outrigger after the transition

 crank mechanism through dead center.

FIG. depicts outriggers in working position, rear view; in fig. 2 scheme remove the supports from the working position in the Transport; in fig. 3 is a section A-A in FIG. 2; on fng. 4 is a section BB in FIG. .

Outrigger supports 1 installed turn. but with folding brackets 2

on the crossbeam 3 chassis. Crosswise

15, the beam 3 is equipped with cranks 4, which are connected through rods 5 with outriggers 1 through cranks 5. Each of the cranks 4 of the opposite sides of the chassis is equipped with a lever 6 pivotally connected with help of a force mechanism 7 with a three-arm such as hydraulic cylinder 9. In addition. in the cross beam 3 fixed stops 10,

having a conical surface. Each seal 0 is provided with an adjustment ring 11,

The device is working - in a mediated manner .-,

. To transfer the supports from the transport position to the working position, the three-arm lever 8 is turned by a hydraulic cylinder 9. At the same time, the crank 7, located on each side of the chassis, rotate the arms 7 through the levers b. This, in turn, through a crank mechanism causes the outriggers 1 to turn outward from the vehicle body. The rotation of the outriggers is limited by the stops 10, the interacting conical surfaces with the cranks 4.

The workloads from the outrigger supports 1 through the brackets 2, and also through the connecting rods 5 and cranks 4 are transferred to the crossbar 3 utaccH, while the crank mechanism stops at the expense of the interaction of the cranks 4 that have passed the dead point with the stops 0, those are the most removed Effort with hydraulic cylinder 9.

The lugs 10 are provided with adjusting rings I, which allows the axial movement of the lugs 10 to ensure the interaction of their conical surfaces with the cranks 4, located on each side of the chassis, for a given operating position of the supports 1.

This embodiment of the device for fixing the outriggers simplifies the power drive of the aggregate and relieves the force mechanism during the working position of the supports, which increases reliability and allows reducing

intensity and complexity of manufacturing the product.
