Problems solved by technology

The climbing belt climbing tower crane developed in recent years has the hydraulic system as a whole to climb randomly together without disassembly, which can reduce working hours and manpower, but there are also some safety hazards. The climbing claws can accurately and reliably step on the climbing There may also be hidden dangers of slipping on the climbing belt steps or misoperation of the hydraulic system causing accidents

Embodiment

[0049] Example: such as figure 1 , figure 2 As shown, a climbing belt type climbing safety facility for a tower crane in the present invention includes a climbing belt 2, a climbing belt holder 6 and a climbing claw restraint device, and the climbing belt holder 6 is arranged at both ends of the tower crane jacking beam 5 and the positions close to the supporting claws 41 on both sides of the climbing section 4 of the tower crane, the guide rails on both sides of the climbing belt 2 pass through the chute of the climbing belt cage 6, and the climbing belt cage 6 slides along the climbing belt 2 during the climbing process of the tower crane , to ensure that the climbing belt 2 and the rotating support shaft 52 of the climbing claw 51 have a relatively fixed horizontal distance; the climbing claw restraining device is arranged on the climbing belt 2, close to the position of the step 21, and constrains the crawling claw to the climbing belt step 21, When the hydraulic cylinde...

Embodiment 2

[0058] Embodiment 2: The difference between this embodiment and Embodiment 1 is: taking the climbing claw constraint on the jacking beam 5 as an example, as image 3 As shown, the climbing belt restraint device described in this example has climbing claw restraining rod mounting holes correspondingly on the climbing claw 51 and the climbing belt 2, after the climbing claw 51 steps on the step 21 of the climbing belt 2, through Claw 51 and crawler belt 2 corresponding restraint rod installation holes penetrate climbing claw restraint rod 23, and this example climbs claw restraint rod 23 and adopts pin shaft, and restrains crawler claw 51 at crawler belt stepping 21 places. In the locked state of the crawling paw restraint rod 23, it is ensured that the lifting movement of the hydraulic cylinder can be stuck, so as to prevent the hydraulic cylinder from misoperation and causing telescopic movement that endangers safety. The hole of the restraining rod of the climbing claw can al...

Abstract

A climbing belt type climbing safety device for a tower crane belongs to the technical field of construction machinery. It includes a climbing belt, a climbing belt cage and a climbing claw restraint device. The climbing belt cage is arranged at the two ends of the tower crane jacking beam and the two sides of the tower crane climbing section near the supporting climbing claws. The climbing belt passes through the climbing belt and is kept During the climbing process of the tower crane, the climbing belt cage slides along the climbing belt to ensure that the climbing belt and the climbing claw rotation support shaft have a relatively fixed horizontal distance; Climb on the steps. The invention can ensure that the climbing claws can step on the treads of the climbing belt accurately every time, and can also prevent the crawling claws from detaching from the treads of the climbing belt during work; moreover, when the hydraulic cylinder of the hydraulic system of the tower crane is misoperated , to block the movement of the hydraulic cylinder, which solves the safety hazards in the climbing process of the climbing belt tower crane.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, in particular to a climbing belt type climbing safety device for a tower crane. Background technique [0002] At present, internal climbing and external tower cranes are widely used in high-rise and super high-rise buildings. The climbing belt climbing tower crane developed in recent years has the hydraulic system as a whole to climb randomly together without disassembly, which can reduce working hours and manpower, but there are also some safety hazards. The climbing claws can accurately and reliably step on the climbing There may also be hidden dangers of accidents caused by slippage on the climbing belt steps or misoperation of the hydraulic system. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the present invention provides a climbing belt-type climbing safety facility for tower cranes, which fixes the horizontal distance between the cl...
