Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hoisting of power plant equipment, in particular to a electric hoist track migration platform for hoisting hole of middle layer of building. BACKGROUND

[0002] Electric hoist is the core equipment of equipment maintenance, and is widely used in the industrial fields such as thermal power generation, mining, port loading and unloading, etc. In the equipment maintenance operation, the equipment is hoisted by the electric hoist, and is transported to the ground layer of the building through the hoisting hole. The hoisting hole positions of different floors of the multi-storey building are overlapped upwards and downwards, and the electric hoist of the uppermost layer can transport the maintenance equipment to the ground layer through the hoisting hole. In order to avoid affecting the operation of the electric hoist of the upper layer, the operation track of the electric hoist of the middle floor is usually fixedly installed on one side of the hoisting hole, and when the equipment is maintained, the steel wire rope of the electric hoist needs to be manually pulled to make the steel wire rope inclined, and then the equipment is hoisted. This operation mode has great safety hazards, for example, the uneven force on the steel wire rope may cause breakage or equipment falling; the operator needs to be close to the hoisting area, which has the risk of being hit or squeezed by heavy objects; manual adjustment has low precision, which easily causes the equipment to shake and affects the stability of hoisting; since the angle of the steel wire rope needs to be frequently adjusted, the operation process is complex, which prolongs the maintenance time and increases the equipment maintenance workload; manual intervention increases the labor intensity and reduces the overall operation efficiency. In the conventional case, in order to avoid manual dragging, multiple hoisting holes need to be opened on each floor of the building to meet the requirement that the electric hoist of each floor can be hoisted to the ground layer, which increases the engineering cost and reduces the usable area of the building.

The rolling bearing is connected to the outer main shaft of the right wheel 3-2 by an expansion sleeve. The lower part of the right fixed frame 5-2 is connected to the top of one end of the movable hoist track 8 by welding.

[0041] like Figure 1 , Figure 3 As shown, the second migration track 2 is equipped with a second traveling wheel 4 that moves along the track direction. The second traveling wheel 4 includes a left wheel 4-1 and a right wheel 4-2. The second fixed frame 6 includes a left fixed frame 6-1 and a right fixed frame 6-2. The upper part of the left fixed frame 6-1 is provided with an opening, and a rolling bearing is installed in the opening. The rolling bearing is connected to the outer main shaft of the left wheel 4-1 by an expansion sleeve. The lower part of the left fixed frame 6-1 is connected to the top of the other end of the movable hoist track 8 by welding. The upper part of the right fixed frame 6-2 is provided with an opening, and a rolling bearing is installed in the opening. The rolling bearing is connected to the outer main shaft of the right wheel 4-2 by an expansion sleeve. The lower part of the right fixed frame 6-2 is connected to the top of one end of the movable hoist track 8 by welding.

[0042] like Figure 1 , Figure 3 As shown, the middle part of the right fixed bracket 6-2 of the second fixed bracket 6 is bolted to the drive motor 9. A gear is mounted on the output shaft of the drive motor 9, and a gear is also mounted on the outer side of the right wheel 4-2 of the second traveling wheel 4. During operation, the gear on the output shaft of the drive motor 9 and the gear on the outer side of the right wheel 4-2 of the second traveling wheel 4 mesh to transmit power. A cable slide rail 10 is located below the lifting hole 15 on the same side of the drive motor 9. The cable slide rail 10 is bolted to the upper outer side of the right fixed bracket 6-2, and works in conjunction with the drive motor 9. It should be noted that the drive motor 9 and the cable slide rail 10 can also be mounted on the first fixed bracket 5.

[0043] like Figure 1 , Figure 2 , Figure 3 As shown, the first traveling wheel 3 and the second traveling wheel 4 are connected by a drive shaft 7. Specifically, the axis of the right wheel 3-2 of the first traveling wheel 3 coincides with the axis of the drive shaft 7 and is connected by welding; the axis of the left wheel 4-1 of the second traveling wheel 4 coincides with the axis of the drive shaft 7 and is connected by welding.

[0044] likeFigure 1 As shown, a fixed hoist rail 11, which mates with the movable hoist rail 8, is located below the lifting hole 15. An electric hoist 12 is mounted on the fixed hoist rail 11. The fixed hoist rail 11 and the movable hoist rail 8 are of the same model. The fixed hoist rail 11 is welded to the building structure beam and remains in a fixed position after installation. Specifically, during the installation and commissioning phase, the movable hoist rail 8 is first commissioned into its working state, i.e., located within the working space of the lifting hole 15, for example, directly below the center of the lifting hole 15. At this point, the fixed hoist rail 11 and the movable hoist rail 8 are spatially aligned. Maintaining this state, the fixed hoist rail 11 is then fixedly installed.

A movable hoist rail stop 13 is provided at the end of the movable hoist rail 8 to limit the range of motion of the electric hoist 12 and prevent it from falling off.

[0045] The implementation principle of an electric hoist track transfer platform for a hoisting hole in the middle floor of a building according to an embodiment of this application is as follows: When the drive motor 9 is working, the gear on the output shaft of the drive motor 9 is driven, and the gear and the gear on the traveling wheel 4 are meshed to transmit power, causing the traveling wheel 4 to rotate. When the traveling wheel 4 moves along the transfer track 2, the main shaft of the traveling wheel 4 drives the transmission shaft 7 to rotate synchronously. The transmission shaft 7 drives the traveling wheel 3 on the other side to rotate synchronously along the transfer track 1, so that the traveling wheels at both ends keep rotating synchronously, thereby driving the movable hoist track 8 to move. When in operation, the movable hoist track 8 is moved horizontally to directly below the center of the lifting hole 15 and connected to the fixed hoist track 11. Then, the electric hoist 12 is moved from the fixed hoist track 11 to the movable hoist track 8. At this time, the electric hoist 12 can be positioned directly below the center of the lifting hole 15 for lifting operations. When not in operation, the electric hoist 12 is first moved horizontally to the fixed hoist track 11, and then the movable hoist track 8 is moved horizontally outside the working space of the lifting hole 15 to avoid affecting the operation of electric hoists on other floors.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
