Description
Technical Field
[0001] This utility model relates to a device for high-altitude turnaround hooks, specifically a device for high-altitude turnaround hooks. Background Technology
[0002] During boiler installation, components are often difficult to lift directly to the installation position without obstruction, especially when installing suspended boilers. During the installation process, the hooks of most components are obstructed by the main beams and secondary beams of the furnace top when moving. It is necessary to re-hook the components once or several times before they can be in place. Some components need to be temporarily positioned first, such as the front right water-cooled wall, which is re-hooked in mid-air before being positioned.
[0003] High-altitude hook-up is a time-consuming, troublesome, and dangerous process. Currently, the hook-up procedure is not simplified enough, and its safety and efficiency are not high enough.
[0004] Therefore, a high-altitude slewing hook conversion device is needed to improve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a device for high-altitude turnaround hooks to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A device for a high-altitude slewing hook includes two triangular steel plates. A mandrel is inserted and fixed at the center of the two triangular steel plates. Both ends of the mandrel are located outside the triangular steel plates, and limit bolts are threaded to the outside of both ends of the mandrel. A cable coil is sleeved on the outside of the mandrel. Threaded holes are opened at the four corners inside the triangular steel plates. A limit shaft is inserted through the threaded holes. The limit shaft is inserted into the interior of one triangular steel plate. A threaded safety pin is inserted into the other end of the limit shaft. The mandrel enables the hoisting of the cable coil. When turning is required, the limit shaft on one side can be hoisted to turn the cable coil. The entire triangular steel plate can be turned by removing the limit shaft on one side.
[0008] As a preferred embodiment of this utility model, the triangular steel plate is an equilateral triangular plate.
[0009] As a preferred embodiment of this utility model, the threaded safety pin is inserted into the outside of the limiting shaft, and the threaded safety pin is connected to the internal thread of the limiting shaft.
[0010] As a preferred embodiment of this utility model, the number of limiting shafts is set to three, and the three limiting shafts are distributed inside the three corners of the triangular steel plate. The top limiting shaft is adapted to anchor jacks or hooks, and the cable coil is sleeved on the outside of the mandrel for hoisting.
[0011] As a preferred embodiment of this utility model, the top limiting shaft is adapted to an anchor jack or a hook.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this utility model, the cable coil can be hoisted by the set mandrel. When it is necessary to turn, the limit shaft on the hoisting side can turn the cable coil. The triangular steel plate as a whole can be turned by disassembling the limit shaft on one side.
[0014] 2. In this utility model, the top limiting shaft is adapted to anchor jacks or hooks, and the cable roll is sleeved on the outside of the mandrel for hoisting. Attached Figure Description
