Description

Technical Field

[0001] The invention relates to the technical field of elevators, and in particular to a fixing device for a traveling cable of a jumping elevator. Background Art

[0002] A skip elevator is an elevator used in special scenarios. Ordinary passenger elevators are installed and put into use only after the elevator shaft of the building is completed. However, a skip elevator can be installed and used after the elevator shaft is completed to a certain stage, and can follow the construction progress of the building and change the lifting height according to the actual construction needs. Ordinary passenger elevators mainly serve users of buildings, while skip elevators mainly serve construction workers of buildings. Due to its special purpose, the skip elevator can install part of the elevator structure (such as the elevator hall door, car, car frame, counterweight, guide rails of the shaft, etc.) before the elevator shaft is completed. After the shaft is completed, these installed parts of the skip elevator can be directly retained and become necessary parts of the formally operated elevator. Therefore, the construction progress can be greatly accelerated, so that the elevator can be put into operation earlier after the shaft is completed.

[0003] like Figure 1-5 As shown in the figure, the machine room frame, one of the key components of the jump elevator, needs to undergo a series of hoisting processes when changing the lifting height of the elevator. The hoisting of the machine room frame is divided into 5 stages:

[0004] Phase 1: Elevator stops running

[0005] Phase 2: Cut the traction wire rope, untie the accompanying cable from the elevator, and place the cable reel in the temporary elevator machine room.

[0006] Phase 3: Lifting the temporary elevator machine room.

[0007] Phase 4: Lifting the temporary elevator room support beams.

[0008] Phase 5: Place the temporary machine room on the machine room support beams, reinstall the traction wire rope and accompanying cables, and remove the slings.

[0009] exist Figure 1-5 In the equipment room frame hoisting process shown, it can be seen that the accompanying cables need to be released in stage 2-3. The method of releasing the fixation is to cut the tape that binds the cables, which may damage the cables. Figure 6 Schematic diagram showing the securing of the traveling cable by means of tape.

[0010] In stage 4-5, the accompanying cables need to be re-tied and secured with tape.

[0011] The installation and disassembly process of the above cables is relatively time-consuming. When the number of jumps of the jumping elevator is relatively large, the installation time and the risk of damage to the accompanying cables are greatly increased. Summary of the invention
