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

The invention discloses a climbing belt type climbing safety facility for a tower crane, and belongs to the technical field of construction machines. The climbing belt type climbing safety facility comprises a climbing belt, climbing belt retaining frames and a climbing claw restraint device, wherein the climbing belt maintaining frames are arranged at the two ends of a jacking cross beam of the tower crane and the positions, close to supporting climbing claws, of the two sides of a climbing joint of the tower crane; the climbing belt penetrates through the climbing belt retaining frames, theclimbing belt retaining frames slide along the climbing belt in the climbing process of the tower crane, and it is ensured that the climbing belt and rotating support shafts of the climbing claws havea relatively fixed horizontal distance; and the climbing claw restraint device is arranged on the climbing belt, and the climbing claws are restrained on climbing belt steps. According to the climbing belt type climbing safety facility, it can be guaranteed that the climbing claw steps can be accurately treaded onto the climbing belt steps every time, and the climbing claws are prevented from disengaging from the climbing belt steps during working; and when a hydraulic cylinder of a tower crane hydraulic system is in misoperation, a blocking effect is generated on the movement of the hydraulic cylinder, and the potential safety hazard of the climbing belt type tower crane in the climbing process is solved.

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...
