Transverse locking device for heavy tower crane

Abstract

The invention discloses a transverse locking device for a heavy tower crane. The transverse locking device structurally comprises a top cover plate, a guide rail locking box groove, a transverse framelifting arm, a rope lifting hook frame seat, a rib rod supporting column frame and a balance weight. According to the transverse locking device for the heavy tower crane, the guide rail locking box groove is matched with the transverse frame lifting arm, a transverse balance weight lifting arm frame rod of the tower crane is matched with a machine box groove shell to form one pull buckle mountingeffect through a left wheel buckle disc and roller pad truss plates, and the pad rotation stability of the line distance is guaranteed; and the safety coefficient and the anti-disengaging stability of the transverse frame lifting arm of the whole heavy tower crane are improved through the firmness of flexible disassembly and tightening of a pull buckle pad petal groove, the safety range of groundworkers and the high-altitude hoisting balance framework effect are guaranteed, and the operation effect of uniform regulation and control over the flexibility and the tension degree of subsequent transverse vibration isolation sliding output lifting arm operation is achieved.

Description

technical field [0001] The invention relates to a horizontal locking device of a heavy-duty tower crane, which belongs to the construction field. Background technique [0002] Heavy-duty tower cranes are mobile equipment used to hoist building materials for floor transportation during construction, ensuring effective adjustment of high-altitude horizontal rotation and vertical lifting and adaptation to changes in handling positions. Lifting tower cranes is universal in use, and the current technology Common disadvantages to be optimized are: [0003] The beam boom of the heavy-duty tower crane needs to be articulated with rivets and sockets, and when the rivets fall off, the bolts of the pins are easy to sway and loosen the boom, which will affect the load-bearing capacity of the tower crane and the adjustment of the counterweight, causing subsequent booms to work. Fracture and bending deformation will cause the hoisted materials to fall from the sky easily, causing safety ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a horizontal locking device for heavy-duty tower cranes, so as to solve the problem that the crossbeam arm of the heavy-duty tower crane needs to be articulated through rivets and sockets, and the bolts of the pins are easy to swing when the rivets fall off. The arm is loose, which will affect the load-bearing capacity of the tower crane and the adjustment of the counterweight, resulting in the subsequent breakage and bending deformation of the boom during work, causing the hoisted materials to fall from the sky easily, causing safety hazards to the ground construction personnel and affecting the tower crane. The problem that the degree of firmness cannot be guaranteed
