Telescopic bridge of high-altitude operation vehicle

Abstract

The invention discloses a telescopic bridge of a high-altitude operation vehicle. The structure of the telescopic bridge comprises a cross beam, a sleeve block, a vertical rod, a hydraulic rod, a control box, a mounting and fixing device, an extension beam, a fixed connection rod, a connection plate, a lifting hook, a movable clamping groove, a pushing oil cylinder and a fulcrum block, wherein theleft side of the cross beam is vertically welded with the vertical rod; the extension beam is arranged under the cross beam and is parallel to the cross beam; the left side of the extension beam is connected with the vertical rod; the sleeve block is arranged on the left side of the lower part of the cross beam; the hydraulic rod is nested in the sleeve block through clearance fit; the control box is mounted on the vertical rod through interference fit; the mounting and fixing device is arranged under the vertical rod; two ends of the fixed connection rod are respectively connected with the connection plate and the movable clamping groove; the connection plate is mounted on the right side of the extension beam through clearance fit; the lifting hook is vertically connected with the rightside of the extension beam; the movable clamping groove is nested on the right side of the cross beam through clearance fit. The fixation of the telescopic bridge can be improved in use, so that the situation of collapse of the telescopic bridge is not easily caused; the telescopic bridge has high safety in use.

Description

technical field [0001] The invention relates to a telescopic bridge for an aerial work vehicle, which belongs to the field of telescopic bridges. Background technique [0002] The usual chassis of boom-type aerial work vehicles is usually an ordinary chassis. The storage space of parts is simplified, the size of tires is widened and the appropriate counterweight is used to control the balance of the equipment in use. In actual use, the equipment has a relatively high extension height, and the safety is not enough. [0003] When the prior art is in use, the installation fixity is average, the situation of collapse is more likely to occur, and the use safety is low. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a telescopic bridge for an aerial work vehicle to solve the problems of the prior art in general installation fixity, prone to collapse and low safety in use. [0005] In order to a...
