Abstract
The utility model discloses a high stability hoist, including shrink dead lever, chassis, top ping lift, jack -up wire rope, swing arm support, rotatory work revolving stage, hoisting accessory and change width of cloth swing arm, the shrink dead lever is fixed on the chassis through the pin, rotatory work revolving stage closes with the chassis soon to be connected, surpassed the device install with become width of cloth swing arm articulated basis arm on, basis arm and swing arm support fixed connection, it is all articulated with the auxiliary to become width of cloth swing arm and swing arm support, the preceding wire rope's of drawing one end with has surpassed the device and be connected, the other end is connected with the head of swing arm support, top ping lift and jack -up wire rope's one end is connected on the swing arm support, and the other end is fixed on the afterbody of rotatory work revolving stage. This high stability hoist auxiliary makes the swing arm support can not take place the vibration and sway through basic arm and swing arm support fixed connection, makes change width of cloth swing arm more stable at the during operation to the stationarity of hoist work has been improved.
Description
Technical field
The utility model relates to a kind of engineering mechanical device field, is specially a kind of high stability hoisting crane.
Background technology
At present, the important tool that hoisting crane is indispensable in producing as engineering, along with hoisting crane develops to large-tonnage, fixing auxiliary, tower auxiliary and the utilization of luffing swing arm on hoisting crane, the pressure of principal arm head sharply increases, because principal arm cephalad arm joint cross section composite bending modulus is little, cause the structural stress at this place larger, the local buckling of easy side, generation cross section and cross section lower area, by on principal arm, install super lifting device additional produce act on principal arm hogging moment to reduce the sagging moment that weight acts on principal arm, just seem very important.
Utility model content
The purpose of this utility model is to provide a kind of high stability hoisting crane, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of high stability hoisting crane, comprises contraction fixed link, chassis, variable-amplitude steel wire rope, hoist rope, super lifting device, before draw steel rope, arm carrier, luffing assembly, rotary work turntable, main arm amplitude-changing mechanism, principal arm, basis arm, auxiliary, lifting appliance and luffing swing arm, described contraction fixed link is fixed by a pin on chassis, described rotary work turntable screws with chassis and is connected, described super lifting device is arranged on the basic arm hinged with luffing swing arm, described basic arm is fixedly connected with arm carrier, described principal arm is connected with auxiliary by basic arm, described luffing swing arm and arm carrier are all hinged with auxiliary, described lifting appliance to be rolled with luffing swing arm by roller and is connected, one end of steel rope is drawn to be connected with super lifting device before described, the other end is connected with the head of arm carrier, one end of described variable-amplitude steel wire rope and hoist rope is connected on arm carrier, and the other end is fixed on the afterbody of rotary work turntable.
Preferably, described arm carrier upwards extends from the left side of basic arm.
Preferably, the root of the cross-sectional area slave arm support of described arm carrier diminishes gradually to head.
Compared with prior art, the beneficial effects of the utility model are: this high stability crane subsidiary arm is fixedly connected with arm carrier by basic arm, make arm carrier vibration can not occur and wave, make luffing swing arm operationally more stable, thus improve the stationarity of hoisting crane work.
Accompanying drawing explanation
