Description

Technical Field

[0001] This utility model belongs to the field of winch technology, and in particular relates to a winch for water conservancy construction. Background Technology

[0002] A winch is a small, lightweight lifting device that uses a drum to wind a steel wire rope or chain to lift or pull heavy objects. In water conservancy projects, gates are typically installed at the dam to control water flow. Currently, winches are generally used to raise and lower the gates. However, because one end of the steel wire rope is directly connected to the upper end of the gate, the gate's ascent is time-consuming and labor-intensive, requiring a high-powered motor to complete the operation, thus increasing construction and maintenance costs. Utility Model Content

[0003] To address the above problems, this utility model provides a winch for hydraulic construction.

[0004] This utility model is implemented as follows: A winch for hydraulic construction includes a base frame. Supports are vertically and symmetrically fixed at the midpoints of both sides of the upper end of the base frame. Bearing seats are fixedly mounted at the upper ends of the supports. A roller is horizontally arranged between the bearing seats. A shaft is horizontally and symmetrically fixed at the midpoints of both ends of the roller. The shaft passes through the center of the bearing in the corresponding bearing seat and is fixedly connected to the bearing, ensuring the stability of the roller's position. The shaft drives the roller to rotate smoothly along the bearing. A motor and a reducer are mounted on one side of the base frame. The drive shaft of the motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the end shaft of the shaft. The motor drives the roller to rotate, and the reducer reduces the roller's speed, ensuring that the roller stably winds or unwinds the wire rope. A continuous first rope groove is formed on one side of the outer wall of the roller, and a continuous second rope groove is formed on the other side of the outer wall of the roller. Wire rope is wound in both the first and second rope grooves, defining the position of the wire rope and facilitating a tight arrangement of the wire rope on the roller.

[0005] A baffle is horizontally and symmetrically fixed at the center of the base frame. A rectangular steel pipe is vertically installed between the baffles. A first pin is horizontally installed at the upper part of the steel pipe and the baffle, reliably connecting the upper part of the steel pipe to the baffle and ensuring the stability of the steel pipe's position. A second pin is horizontally installed at the lower part of the steel pipe. A first pulley is installed on the second pin inside the steel pipe, ensuring the stability of the first pulley's position. The first pulley can rotate freely along the second pin. A sleeve with an open top is installed at the bottom of the base frame to facilitate the movement of the wire rope. A vertical plate is vertically installed near the outer wall of the sleeve. A third pin is horizontally installed at the upper part of the sleeve and the vertical plate, ensuring the stability of the sleeve and the vertical plate's position. The reliable connection of the plates is ensured by the fact that the second and third pulleys are provided on the third pin shaft to guarantee the stability of their positions. The second and third pulleys can rotate freely along the third pin shaft. The wire rope on the first rope groove wound on the second pulley passes around the first pulley and is connected to the wire rope on the second rope groove wound on the third pulley. The second and third pulleys serve as movable pulleys, and the first pulley serves as a fixed pulley. The winding operation of the wire rope by the roller greatly reduces the force required to lift the gate. A fourth pin shaft is horizontally provided at the bottom of the vertical plate to limit the position of the wire rope. A section of wire rope reliably connects the fourth pin shaft to the upper end of the gate.

[0006] Preferably, the two rollers are fixedly connected together by a connecting rod, and the gate is lifted by the two rollers together, which further reduces the force required.

[0007] Preferably, a retaining ring is fixedly provided on the outer wall of the roller between the first rope groove and the second rope groove to separate the wire ropes on both sides of the retaining ring and prevent the wire ropes from getting tangled together.

[0008] Preferably, the base frame is hollow inside to facilitate the smooth movement of the wire rope.

[0009] Preferably, a support block is fixedly provided at the lower end of the motor and the reducer to ensure the stability of the position of the motor and the reducer.

[0010] Preferably, the reducer is a planetary reducer, which has a good deceleration effect.

[0011] The beneficial effects of this utility model are: the first pulley can rotate freely along the second pin, and the second and third pulleys can rotate freely along the third pin. The wire rope on the first rope groove wound on the second pulley passes around the first pulley and is connected to the wire rope on the second rope groove wound on the third pulley. The second and third pulleys serve as movable pulleys, and the first pulley serves as a fixed pulley. By winding the wire rope with the roller, the force required to lift the gate is greatly reduced. The working requirements can be met without replacing the high-power motor, thus reducing construction and maintenance costs. Attached Figure Description

[0017] To better understand the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, further illustrates this utility model.

[0018] like Figure 1-4The image shows a winch for hydraulic construction, comprising a base frame 1. The base frame 1 is hollow to facilitate the smooth movement of the wire rope 10. Supports 2 are vertically and symmetrically fixed at the midpoint of the upper sides of the base frame 1. Bearing seats 3 are fixedly fixed at the upper ends of the supports 2. Rollers 4 are horizontally arranged between the bearing seats 3. Axles 5 are horizontally and symmetrically fixed at the midpoint of both ends of the rollers 4. The axles 5 pass through the center of the bearings within the corresponding bearing seats 3 and are fixedly connected to the bearings, ensuring the stability of the rollers 4. The axles 5 drive the rollers 4 to rotate smoothly along the bearings. A motor 6 and a reducer 7 are arranged on one side of the base frame 1. Support blocks 24 are fixedly installed at the lower ends of the motor 6 and reducer 7 to ensure the stability of their positions. The reducer 7 is a planetary reducer, providing good deceleration. The drive shaft of the motor 6 is connected to the input shaft of the reducer 7, and the output shaft of the reducer 7 is connected to the end shaft of the shaft 5. The motor 6 drives the drum 4 to rotate, and the reducer 7 reduces the speed of the drum 4 to ensure that the drum 4 can stably wind or unwind the wire rope 10. A continuous first rope groove 8 is provided on one side of the outer wall of the drum 4, and a continuous second rope groove 9 is provided on the other side of the outer wall of the drum 4. Wire rope 10 is wound on both the first rope groove 8 and the second rope groove 9 to limit the position of the wire rope 10 and facilitate the tight arrangement of the wire rope 10 on the drum 4. A retaining ring 23 is fixedly provided on the outer wall of the drum 4 between the first rope groove 8 and the second rope groove 9 to separate the wire rope 10 on both sides of the retaining ring 23 and prevent the wire rope 10 from getting tangled together.A baffle 11 is horizontally and symmetrically fixed at the center of the base frame 1. A rectangular steel pipe 12 is vertically arranged between the baffles 11. A first pin 13 is horizontally arranged through the upper part of the steel pipe 12 and connected to the baffle 11, ensuring a reliable connection between the upper part of the steel pipe 12 and the baffle 11 and stabilizing the position of the steel pipe 12. A second pin 14 is horizontally arranged through the lower part of the steel pipe 12. A first pulley 15 is arranged on the second pin 14 inside the steel pipe 12, ensuring the stability of the first pulley 15 and allowing it to rotate freely along the second pin 14. A sleeve 16 with an open top is arranged at the bottom of the base frame 1 to facilitate the movement of the wire rope 10. A vertical plate 17 is vertically arranged near the outer wall of the sleeve 16. A third pin 18 is horizontally arranged through the upper part of the sleeve 16 and the vertical plate 17 to ensure the stability of the sleeve. The reliable connection between 16 and vertical plate 17 is achieved by providing a second pulley 19 and a third pulley 20 on the third pin 18 to ensure the stability of the positions of the second pulley 19 and the third pulley 20. The second pulley 19 and the third pulley 20 can rotate freely along the third pin 18. The wire rope 10 wound on the first rope groove 8 on the second pulley 19 passes around the first pulley 15 and is connected to the wire rope 10 wound on the second rope groove 9 on the third pulley 20. The second pulley 19 and the third pulley 20 serve as movable pulleys, and the first pulley 15 serves as a fixed pulley. The winding operation of the wire rope 10 by the roller 4 greatly reduces the force required to lift the gate. A fourth pin 21 is horizontally arranged through the lower part of the vertical plate 17 to limit the position of the wire rope. A section of wire rope reliably connects the fourth pin 21 to the upper end of the gate.

[0019] The two rollers 4 are fixedly connected together by a connecting rod 22. The gate is lifted by the two rollers 4 together, which further reduces the force required.
