Description

Technical Field

[0001] This utility model relates to the field of gate hoisting technology, and more specifically to a suspended mobile gate hoisting mechanism. Background Technology

[0002] Suspended gate hoists are key pieces of equipment commonly used in water conservancy projects, primarily for controlling the lifting and lowering of gates. Their core structure includes a horizontally fixed beam, I-beam rails at both ends, and an adjusting and lifting device that can move along the rails. The lifting device typically consists of rollers, a reducer, a motor, and a transmission mechanism with wound steel wire ropes. Precise gate opening and closing is achieved through frequency conversion or manual operation. They are mainly used in reservoirs, rivers, and irrigation areas, featuring flexible operation, simple maintenance, and high stability, and perform particularly well in small and medium-sized water conservancy facilities requiring frequent gate opening and closing.

[0003] However, some shortcomings have been found in the actual use of suspended gate hoists, such as insufficient buffering performance, lack of flexible buffering capability in pure mechanical transmission, and sudden load impact (such as gate jamming or foreign object impact) may cause component damage (such as drive shaft deformation or bolt breakage). Utility Model Content

[0004] One advantage of this invention is that it provides a suspended mobile gate hoist with a buffer start component, which can cope with the two largest load situations in the use of the suspended gate hoist. When the gate is first started, the hydraulic system bears the large load when it changes from stationary to moving. After the gate starts moving, the motor takes over. At the same time, when encountering a sudden load impact, the sudden load can also be absorbed by the buffer start component, preventing the drive shaft, bolts, etc. from bearing the sudden load.

[0005] To achieve at least one of the above advantages of this utility model, this utility model provides a suspended mobile gate hoist, including a horizontally arranged crossbeam, with I-beams fixedly installed at both ends of the crossbeam, and a traveling component arranged at the lower part of each of the I-beams in a laterally movable manner. A frame is fixedly installed at the lower end of the traveling component, and a lifting component is installed at the lower end of the frame. The lifting component includes a shell fixedly connected to the frame, and two synchronously rotating rollers are rotatably arranged inside the shell. Steel wire ropes are wound on the rollers. A motor is also fixedly installed inside the shell, and the output shaft of the motor is connected to the rollers and drives the rollers to rotate. A buffer starting component is fixedly installed at the lower end of the shell.

[0006] It also includes a gate, the upper end of which is rotatably equipped with four support pulleys, which are divided into two groups, each corresponding to one of the two lifting components;

[0007] In any lifting component and its corresponding set of support pulleys, one end of the wire rope is fixedly connected to one of the rollers, and the other end passes through the support pulley, the buffer starting component and another support pulley in sequence before being fixedly connected to another roller.

[0008] According to one embodiment of the present invention, a speed reducer is also provided inside the outer casing, and the speed reducer is connected to the roller.

[0009] Several bearing seats are fixedly installed at the lower end of the crossbeam, and a synchronous shaft is rotatably connected to the bearing seats. Splines are provided at both ends of the synchronous shaft and connected to two reducers through the splines.

[0010] According to one embodiment of the present invention, the walking assembly includes a side plate fixedly connected to the frame, and a walking wheel is rotatably provided on the side plate, the walking wheel being coupled to an I-beam.

[0011] According to one embodiment of the present invention, the buffer start assembly includes a protective cover fixedly disposed at the lower end of the outer shell. The protective cover has a blind hole inside, and a spring damper is fixedly installed in the upper part of the blind hole. A hydraulic cylinder is fixedly installed in the spring damper. A mounting seat is fixedly disposed at the lower end of the piston rod of the hydraulic cylinder. A main pulley is rotatably disposed on the mounting seat, and a wire rope passes through a groove on the main pulley.

[0012] According to one embodiment of the present invention, the spring damper includes an outer sleeve and an inner sleeve. The upper middle part of the inner sleeve is installed inside the outer sleeve in a way that allows it to slide up and down. After the outer sleeve and the inner sleeve are connected, a cavity is formed inside the two sleeves. A spring and a damping medium are disposed inside the cavity.

[0013] Several support rods are fixedly installed on the inner wall of the blind hole. The other end of the support rods is fixedly connected to the lower end of the inner sleeve.

[0022] The first embodiment of this utility model is as follows:

[0023] A suspended mobile gate hoist includes a transversely arranged crossbeam 3, with I-beams 1 fixedly installed at both ends of the crossbeam 3. The lower part of each I-beam 1 is provided with a traveling component 2 in a transversely movable manner. The traveling component 2 includes a side plate fixedly connected to a frame 15. A traveling wheel 14 is rotatably provided on the side plate. The traveling wheel 14 is coupled to the I-beam 1 and can move laterally on the I-beam 1 and the crossbeam 3 through the traveling wheel 14.

[0024] The frame 15 is a frame structure made of steel, extending downwards from both sides of the crossbeam 3. A lifting assembly is installed at its lower end. The lifting assembly includes a housing 11 fixedly connected to the frame 15. Inside the housing 11, two synchronously rotating rollers 6 are rotatably arranged and connected by a drive shaft. Steel wire ropes 7 are wound on the rollers 6. The connection points between the steel wire ropes 7 and the rollers 6 are all located at the outer ends of the rollers 6. A motor 5 is also fixedly installed inside the housing 11. The output shaft of the motor 5 is connected to the rollers 6 and drives the rollers 6 to rotate. During the rotation of the rollers 6, the steel wire ropes 7 are gradually wound onto or unwound from the rollers 6.

[0025] The upper end of the gate 9 is rotatably equipped with four support pulleys 8, which are divided into two groups and correspond to two lifting components respectively.

[0026] In any lifting component and its corresponding set of support pulleys 8, one end of the wire rope 7 is fixedly connected to one of the rollers 6, and the other end passes through the support pulley 8, the buffer starting component 12 and another support pulley 8 in sequence before being fixedly connected to another roller 6. When the roller 6 is working, the wire rope 7 is gradually wound, causing the gate 9 to move up or down.

[0027] The buffer start assembly 12 includes a protective cover 17 fixedly installed at the lower end of the outer casing 11. On the one hand, it protects the spring damper 18 and the hydraulic cylinder 19, and on the other hand, it also serves to connect with the spring damper 18. The protective cover 17 has a blind hole inside, and the spring damper 18 is fixedly installed in the upper part of the blind hole. The spring damper 18 includes an outer sleeve and an inner sleeve. The upper middle part of the inner sleeve is installed inside the outer sleeve in a way that allows it to slide up and down. After the outer sleeve and the inner sleeve are connected, a cavity is formed inside the two. A spring and a damping medium are installed in the cavity. The spring is made of high-quality spring steel and has undergone heat treatment, rust prevention treatment and other processes. It has good elasticity and strength, can withstand the dynamic load generated during operation, and provides stable support and appropriate elastic deformation. The damping medium can be hydraulic oil or silicone. Through the action of viscous resistance, it converts the kinetic energy generated by the vibration of the equipment into heat energy and dissipates it, effectively suppressing the reciprocating vibration of the spring during compression and tension, so that the equipment can quickly reach a stable state.

[0028] When a sudden load impact occurs, the impact energy is transferred to the spring damper 18. The spring first absorbs part of the energy through its own elastic deformation, converting the impact vibration into the spring's extension and contraction motion. At the same time, the damping medium plays a role, and its viscous resistance hinders the rapid extension and contraction of the spring, causing the spring's vibration amplitude and frequency to gradually decrease, converting the remaining vibration energy into heat energy and dissipating it, thereby effectively reducing the transmission of vibration.

[0029] Several support rods are fixedly installed on the inner wall of the blind hole. The other end of the support rods is fixedly connected to the lower end of the inner sleeve. Several connecting rods are fixedly connected to the lower end of the outer sleeve. The lower ends of the connecting rods extend downward from the gap between the adjacent support rods to the bottom of the inner sleeve and are connected to the hydraulic cylinder 19. That is to say, when a sudden load impact occurs, the impact force acts on the upper outer sleeve. Since the inner sleeve is fixed, the outer sleeve will move downward, thereby compressing the spring and causing the spring damper 18 to act.

[0030] The lower end of the piston rod of the hydraulic cylinder 19 is fixedly provided with a mounting base 20. The mounting base 20 is rotatably provided with a main pulley 21. The wire rope 7 passes through the groove on the main pulley 21. When a sudden load impact occurs, the hydraulic system of the hydraulic cylinder 19 will also generate a flexible buffer, which works together with the spring damper 18 to eliminate the impact of the sudden load on the drive shaft or bolt.

[0031] On the other hand, when the gate 9 needs to be lifted from the closed state to the open state, the change from a static to a dynamic state will generate a large load. At this time, the motor 5 does not work, but first drives the hydraulic cylinder 19 to shorten, so that the wire rope 7 is tightened. This generates an upward force on the gate 9, lifting the gate 9 and changing it from a static to a dynamic state. After a preset time, the motor 5 starts, the hydraulic cylinder 19 stops working, and the motor 5 drives the roller 6 to rotate and continue to lift the gate 9 through the wire rope 7. In this way, the load borne by the motor 5 when the gate 9 changes from a static to a dynamic state can be reduced, which is beneficial to extending the service life of the motor 5.

[0032] The outer casing 11 is also equipped with a reducer 10, which is connected to the roller 6. The roller 6 is connected to the synchronous shaft 4 through the spline 16. The function of the synchronous shaft 4 is to connect the two sets of rollers 6 so that the lifting distances at both ends of the gate 9 are the same.

[0033] Several bearing seats 13 are fixedly installed at the lower end of the crossbeam 3. The synchronous shaft 4 is connected to the crossbeam 3 through the bearing seats 13. Even if the synchronous shaft 4 breaks, it will not fall from a height.

[0034] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0035] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
