Abstract

The utility model relates to a sliding block device for a telescopic arm, comprising a protecting board and a rolling device with a rolling surface, wherein the protecting board is fixed at a gap between an inner arm and an outer arm of the telescopic arm, the rolling device is arranged on one side of the protecting board, and the rolling device rolls on the rolling surface front and back to be contacted with the other telescopic part; and the rolling device comprises a plurality of fixed shafts and a plurality of rolling columns forming into the rolling surface, the fixed shafts are arranged on a groove at one side face of the protecting board, and the rolling columns are arranged on the fixed shafts. The sliding block device for the telescopic arm in the utility model is simple in structure, the protecting board is fixed on the inner arm and the outer arm at the gap between the inner arm and the outer arm of the telescopic arm, the rolling device is arranged in the groove at one side face of the protecting board, and the original sliding friction is changed into the existing rolling friction, so that the frictional force among arm brackets can be reduced, the wearing speed of each part can be reduced, the service life can be prolonged, and the production cost can be reduced, so that the sliding block device can be popularized and used in wide range.

Description

A kind of telescopic boom slide block device
Technical field
The utility model relates to a kind of telescopic boom slide block device.
Background technique
Like hoist, high-altitude operation vehicle, elevating fire truck etc., the considerable part product specification has telescopic jib in engineering vehicle.The inner arm of telescopic boom is installed in the outer arm, and slide block device is equipped with in the gap that is positioned at inside and outside arm at the two ends of telescopic boom.The front-slider device is fixed on the outer arm, and the rear slider device is fixed on the inner arm.When operation, stretch out in its inner arm to the outer arm, and produce the effect of power each other through slide block device.But existing slide block device is the plane with the surface of contact of jib; The coefficient of sliding friction is high, and the frictional force between jib is bigger, and structure is comparatively complicated.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of telescopic boom slide block device simple in structure, easy to use.
The telescopic boom slide block device of the utility model; Comprise backplate and the tourelle of a rolling surface is arranged; Backplate is fixed on the inner arm of telescopic boom and the gap location between the outer arm; Tourelle is installed on the side of backplate, and tourelle contacts with another telescopic section through the scroll forward and backward on rolling surface; Said tourelle comprises a plurality of stationary axle and a plurality of rollers that constitute rolling surface, and stationary axle is installed in the groove of backplate one side, and roller is installed on the stationary axle.
The telescopic boom slide block device of the utility model, said backplate are fixed on the inner arm and outer arm of telescopic boom inner arm and outer arm gap location.
The telescopic boom slide block device of the utility model, the top rolling surface that said a plurality of rollers form exceeds the top end of backplate slightly.
The telescopic boom slide block device of the utility model, said groove are rectangular recess, and the bottom end of groove is a plane.
The telescopic boom slide block device of the utility model is symmetrically arranged with two threaded mounting holes respectively on the backplate on said groove left side and right side.
Compared with prior art the beneficial effect of the utility model is: the telescopic boom slide block device of the utility model is simple in structure, through fixing backplate on the inner arm of telescopic boom inner arm and outer arm gap location and outer arm, tourelle is installed in the groove of backplate one side; The telescopic boom slide block device becomes present rolling friction by original sliding friction; Reduce the frictional force between jib, reduced the rate of wear of each parts, prolonged working life; Cost of production is low, suits to apply on a large scale.
