Description

Technical Field

[0001] The utility model relates to the technical field of replacement of hot water pipes in pipe wells, in particular to a hoisting device for vertical pipes in high-rise pipe wells. Background Technique

[0002] High-rise pipe wells are spaces in high-rise buildings for centrally arranging vertical equipment pipelines, including various types such as cable wells, water supply wells, and smoke exhaust wells. These wells can ensure the smooth installation and operation of equipment such as cables, water pipes, and air ducts, and are an indispensable part of high-rise buildings. They not only save space but also facilitate the maintenance and repair of equipment. Since the existing pipe wells have a certain depth, when maintenance, disassembly, and replacement are required, an electric hoist is needed to hoist and remove the pipeline. However, due to the limited space in the pipe well, it is troublesome to install the electric hoist and the work efficiency is low. Therefore, we propose a hoisting device for vertical pipes in high-rise pipe wells. Content of the Utility Model

[0003] The purpose of the utility model is to provide a hoisting device for vertical pipes in high-rise pipe wells to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A hoisting device for vertical pipes in high-rise pipe wells includes a mounting plate, a fixed bracket is welded on the mounting plate, a motor is installed on the outer wall of the fixed bracket, and the output end of the motor is connected with a winding roller. A steel wire rope is wound around the winding roller. An L-shaped bearing plate is horizontally slidably connected to the mounting plate, and a fixed seat is installed on the L-shaped bearing plate. A pulley adapted to the steel wire rope is provided in the fixed seat. The other end of the steel wire rope is installed with a hook. A U-shaped moving frame is slidably connected to the mounting plate, and an adjusting mechanism for adjusting the horizontal position of the L-shaped bearing plate is provided in the U-shaped moving frame.

[0006] Further: The opening end of the U-shaped moving frame faces the top wall of the mounting plate. The adjusting mechanism includes a reduction motor, which is located on the rear outer wall of the U-shaped moving frame. The output end of the reduction motor is connected with a driving shaft, and the bottom end of the driving shaft is rotatably connected to the inner wall of the U-shaped moving frame through a bearing. A traveling gear is sleeved on the driving shaft. A plurality of meshing grooves are opened on the top wall of the mounting plate, and the meshing grooves are meshed with the traveling gear.

[0007] Further: Two T-shaped grooves are opened on the mounting plate, and a T-shaped slider is slidably connected in each T-shaped groove, and the T-shaped slider is connected to the outer wall of the opening end of the U-shaped moving frame.

[0008] Further: The pulley is rotatably connected to the inner wall of the fixed seat.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] Through the operation of the motor, the steel wire rope on the winding roller can be wound or released. With the cooperation of the pulley, the hook at the bottom end of the steel wire rope can be guided. The lifting and lowering of the hook can facilitate the removal and replacement of the hot water supply and return pipes in the high-rise pipe well, replacing the method of using an electric hoist for hoisting. Through the operation of the reduction motor on the adjusting mechanism, the traveling gear on the driving shaft can be driven to rotate. Since the traveling gear is meshed and connected with multiple meshing grooves and the U-shaped moving frame is slidably limited by the T-shaped slider in the T-shaped groove, the lateral position of the pulley in the fixed seat can be quickly adjusted, and the position of the hook at the bottom end of the steel wire rope can be adjusted according to the size of the pipe well space, with little limitation in use.

[0017] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a hoisting device for vertical pipes in high-rise pipe shafts, including a mounting plate 1, a fixed bracket 2 is welded on the mounting plate 1, a motor 3 is installed on the outer wall of the fixed bracket 2, and the output end of the motor 3 is connected to a winding roller 8. A steel wire rope 4 is wound around the winding roller 8. An L-shaped bearing plate 9 is horizontally slidably connected to the mounting plate 1, and a fixed seat 5 is installed on the L-shaped bearing plate 9. A pulley 6 adapted to the steel wire rope 4 is provided in the fixed seat 5. The other end of the steel wire rope 4 is installed with a hook 7. A U-shaped moving frame 10 is slidably connected to the mounting plate 1, and an adjusting mechanism for adjusting the horizontal position of the L-shaped bearing plate 9 is provided in the U-shaped moving frame 10.

[0018] The mounting plate 1 can be connected to the ground of the high-rise pipe shaft by screws. Before use, the electrical ends of all electrical equipment are electrically connected to an external power supply and the electrical end of a controller. The hoisting device is installed on the highest floor for each hoisting. The steel wire rope 4 and the hook 7 extend to the first floor for hoisting. A solid screw is passed through the seamless steel pipe, and nuts are tightened at both ends and welded firmly. The hook 7 is hung on a special hoisting belt, and the screw is hung below. After the motor 3 is started, the operation of the motor 3 drives the winding roller 8 to rotate. The steel wire rope 4 drives the hook 7 to hoist the pipes section by section for welding upwards. Among them, in order to prevent the pipes from shaking and facilitate welding butt joints, a backing support needs to be set layer by layer. After all the upper and lower pipes are welded, the vertical pipe center and the sleeve center of the floor slab are positioned in a straight line through the hoisting device, and then a fixed support is set for each floor; the adjusting mechanism can adjust the horizontal position of the fixed seat 5 fixedly connected to the L-shaped bearing plate 9, which is convenient for the hook 7 to extend into the pipe shaft, and the position of the hook at the bottom end of the steel wire rope can be adjusted according to the size of the pipe shaft space, with little use limitation.

[0019] Among them, preferably, the opening end of the U-shaped moving frame 10 faces the top wall of the mounting plate 1. The adjusting mechanism includes a reduction motor 11. The reduction motor 11 is located on the rear outer wall of the U-shaped moving frame 10.

A traveling gear 13 is sleeved on the driving shaft 12. A plurality of meshing grooves 14 are formed on the top wall of the mounting plate 1, and the meshing grooves 14 are meshed with the traveling gear 13;

[0020] By the operation of the reduction motor 11, the traveling gear 13 on the driving shaft 12 can be driven to rotate. Since the traveling gear 13 is meshed with a plurality of meshing grooves 14 and the U-shaped moving frame 10 is slidably limited by a T-shaped slider 16 and a T-shaped groove 15, the horizontal position of the pulley 7 in the fixed seat 5 can be quickly adjusted.

[0021] Preferably, two sets of T-shaped grooves 15 are formed in the mounting plate 1. A T-shaped slider 16 is slidably connected in each set of T-shaped grooves 15, and the T-shaped slider 16 is connected to the outer wall of the open end of the U-shaped moving frame 10; the T-shaped slider 16 is fixedly connected to the outer wall of the open end of the U-shaped moving frame 10. After the sliding limit of the T-shaped groove 15 and the T-shaped slider 16, the position of the fixed seat 5 is prevented from shifting during lateral movement.

[0022] Preferably, the pulley 6 is rotatably connected to the inner wall of the fixed seat 5.

[0023] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
