Abstract
The utility model relates to a wedge-sleeve boom twisting preventing device, which belongs to the technical field of engineering machinery. The wedge-sleeve boom twisting preventing device comprises a left supporting plate (1) and a right supporting plate (1), wherein a shaft (2) is arranged between the left and right supporting plates (1), a bolt (3) is installed on the shaft (2) in a penetrating manner, the shaft (2) is fixedly provided with a lug seat (5) through the bolt (3), and a lap-joint plate (8) is arranged between the rear ends of the left and right supporting plates (1) in a connecting manner and is arranged below the shaft (2). According to the wedge-sleeve boom twisting preventing device, the shaft can be effectively prevented from dropping from the supporting plates, and thus the safety accident of the twisting preventing device can be avoided.
Description
Technical field
The utility model relates to a kind of arm cover of wedge formula anti-twisting equipment, belongs to technical field of engineering machinery.
Background technology
Tower machine, i.e. " tower crane ", claims again by " tower crane ", is a kind of weight-lifting equipment for building operation.The arm of tower crane is one of vital part of tower crane, and it is the constitutional formula weldment being linked together with bearing pin by jib connector by several sections of jibs, and its build guality directly affects tower crane and uses safety and life-span.Existing arm cover of wedge formula anti-twisting equipment comprises two support plates in left and right, between two support plates, be coated with axle, on described axle, be coated with bolt, described bolt attaching nut is installed on whole anti-twisting equipment on axle, but due to support plate thinner thickness, and between axle and support plate, there is certain interval, in use, if bump etc., the situation support plate axle that is distorted easily drops from support plate, thereby thereby makes whole anti-twisting equipment drop and cause safety misadventure from support plate.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of arm cover of wedge formula anti-twisting equipment is provided, and it can effectively prevent that axle from coming off from support plate, has avoided the generation of anti-twisting equipment safety misadventure.
The purpose of this utility model is achieved in that a kind of arm cover of wedge formula anti-twisting equipment, it comprises two support plates in left and right, between the support plate of two of described left and right, be coated with axle, on described axle, be coated with bolt, on described axle, be bolted and be provided with ear seat, two of described left and right are connected with lap plate between support plate rear end, and described lap plate is positioned at axle below.
Compared with prior art, the utlity model has following beneficial effect:
A kind of arm cover of wedge of the utility model formula anti-twisting equipment, it can effectively prevent that axle from coming off from support plate, has avoided the generation of anti-twisting equipment safety misadventure.
