Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a sliding attachment device for a lift. Background Art
[0002] In construction projects, construction elevators are used as special equipment for vertical transportation. The entire main body of the construction elevator runs up and down along the guide rail frame, which is composed of multiple standard sections. In order to ensure the stability of the guide rail frame, the guide rail frame is fixed by attachment, and the attachment spacing is determined according to the cross-sectional type of the standard section. The construction elevator for the flat bridge is attached and fixed to the standard section of the flat bridge tower. Due to the structural influence, the height above the attachment of the entire guide rail frame is relatively large, so additional attachments are required. However, as the flat bridge is raised, the attachment frame installed on it needs to be removed. After the jacking is completed and the elevator guide rail frame is raised, a temporary attachment is installed again. During use, if the operator forgets to remove it, it may cause safety hazards, and the disassembly process is an aerial operation, which involves certain safety hazards and workload. Utility Model Content
[0003] The utility model aims to provide a sliding attachment device for a lift, which solves the disadvantage of great potential safety hazards in traditional technologies and is more convenient to operate.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A sliding attachment device for an elevator comprises a flat bridge climbing frame and a fixed frame, both of which are vertically arranged on the ground, an elevator is arranged on the fixed frame so as to be able to be raised and lowered, a sliding attachment device is arranged between the top of the fixed frame and the flat bridge climbing frame and above the elevator, comprising an attachment frame, an oblique support rod and a guide assembly, the attachment frame is cantilevered on a lifting sleeve of the flat bridge climbing frame, both sides of the attachment frame and the flat bridge climbing frame are supported by oblique support rods, a guide assembly is arranged at the cantilevered end of the attachment frame, the guide assembly is sleeved outside the fixed frame and is attached and constrained to the fixed frame during the lifting and lowering process of the lifting sleeve.
[0006] Preferably, the fixing frame is composed of a plurality of standard sections.
[0007] Preferably, the attachment frame is a frame structure composed of a rod system, and a rectangular frame is provided at one end of the frame.
[0008] Preferably, the guide assembly includes four sets of guide wheel trains, and the four sets of guide wheel trains are respectively arranged at four inner corners of the rectangular frame.
[0009] Preferably, the guide wheel system comprises an X-axis pulley and a Y-axis pulley, the X-axis pulley and the Y-axis pulley are arranged at 90° and can be rotatably mounted on the attachment frame.
[0010] Preferably, when the guide assembly is sleeved on the fixing frame, the four groups of guide wheel systems slide in close contact on the vertical round rods located at the four corners of the fixing frame respectively.
[0011] Preferably, the attachment frame is mounted on the lifting sleeve frame by at least two U-bolts.

[0015] In the utility model, a sliding attachment device is used to slide the top of the fixed frame and the flat bridge climbing frame, so that the fixed frame is attached to the flat bridge climbing frame. On the basis of meeting the construction requirements and effectively preventing the fixed frame from shaking, the safety hazard is also eliminated. The sliding attachment device is raised and lowered along with the jacking sleeve, and the cantilevered end of the sliding attachment device is placed outside the fixed frame.
