Abstract
The utility model provides an extensible roll-proof device for caterpillar excavating machinery and belongs to the field of vehicle security devices, which comprises a U-shaped support, side supports and a fixed plate, wherein a pair of through holes is arranged at the position close to the upper end portion of each side support. The straight line section of the U-shaped support is provided with a plurality of pairs of through holes which are corresponding to the through holes on the side supports. The side supports are hollow. The lower end portions of the U-shaped support are sleeved in the side supports. Hinge pins penetrate through the through holes of the side supports and the through holes of the U-shaped support and are fixed by nuts. The lower ends of the side supports are connected with the fixed plate in threaded mode. The extensible roll-proof device for the caterpillar excavating machinery has the advantages that by means of the technical scheme, the height of the roll-proof device can be quickly reduced so as to enable a vehicle to pass lower areas. The extensible roll-proof device for the caterpillar excavating machinery has the advantages of being simple in structure, convenient to maintain, low in processing cost and the like.
Description
Technical field
The utility model belongs to the safety device of vehicle field, especially relates to a kind of telescopic anti-Rolling device that is used for the crawler-mounted excavator tool.
Background technology
Vehicle travel or operation process in, run into zig zag, dodge or during situation such as centre-of gravity shift, the rollover accident take place easily, cause casualties and property loss, therefore, many vehicles all are equipped with anti-Rolling device, particularly do not have the ceiling vehicle.Common anti-Rolling device is fixed on the car body, is the peak of whole locomotive body, and when running into limit for height bar, bridge or short space, vehicle does not often pass through.
Summary of the invention
Technical problem to be solved in the utility model is: at the deficiencies in the prior art, provide a kind of telescopic anti-Rolling device that is used for the crawler-mounted excavator tool simple in structure, simple to operate.
The technical solution of the utility model is: a kind of telescopic anti-Rolling device that is used for the crawler-mounted excavator tool comprises U type support, side stand and fixed head; Wherein, position near the side stand upper end is provided with a pair of through hole, U type support straight line portion is provided with how corresponding with the through hole on the side stand to through hole and these through holes, side stand is hollow, U type support bottom cover is packed in the side stand, the through hole that bearing pin passes on side stand and the U type support is fixed by nut again, and the side stand lower end is threaded with fixed head.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, can reduce the height of anti-Rolling device rapidly, make vehicle pass through short zone; Have simple in structure, easy to maintenance, advantage such as processing cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure:
1, U type support 2, bearing pin 3, nut
4, fixed head 5, side stand
The specific embodiment
As shown in Figure 1, a kind of telescopic anti-Rolling device that is used for the crawler-mounted excavator tool comprises U type support 1, side stand 5 and fixed head 4; Wherein, position near side stand 5 upper ends is provided with a pair of through hole, U type support 1 straight line portion is provided with how corresponding with the through hole on the side stand 5 to through hole and these through holes, side stand 5 is hollow, U type support 1 bottom cover is packed in the side stand 5, the through hole that bearing pin 2 passes on side stand 5 and the U type support 1 is fixing by nut 3 again, and side stand 5 lower ends are threaded with fixed head 4.
When running into short obstruction or short space, detachable lower nut 3 is extracted bearing pin 2 and is adjusted the position that U type support 1 is fixed, thereby adjusts anti-Rolling device height.Also can lay down U type support 1 or side stand 5, thereby the car body whole height is significantly reduced.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
