Description

Technical Field

[0001] This utility model relates to the field of gate hoisting technology, and in particular to a high-lift gate hoisting machine with high safety. Background Technology

[0002] With the continuous development of industrialization and automation, gate hoists, as important mechanical equipment, are widely used in water conservancy, power, transportation and other fields. Especially in the design of high-lift gate hoists, their performance stability and safety are crucial to ensuring normal production. High-lift gate hoists, as devices capable of providing significant lifting capacity, have the functions of opening, closing and adjusting heavy loads. To ensure the safety of the equipment during long-term use, designers continuously research and improve various functions of gate hoists, especially in terms of improving equipment reliability, reducing failure rates and facilitating maintenance, through a series of innovations and optimizations.

[0003] Existing high-lift gate hoists generally employ a motor-driven system, achieving propulsion through a transmission belt and lead screw mechanism. Common components in this system include a motor, reducer, lead screw, guide seat, and wire rollers, which work together to control the hoist's motion. The transmission belt mechanism drives the lead screw or other drive elements to reciprocate, thereby driving the hoist to complete the opening and closing action. Wire rollers are a crucial component of the hoist, used to guide and organize the wire harness; however, their installation and removal typically require bolt fixing, leading to cumbersome operation and requiring lengthy maintenance and replacement times. Furthermore, traditional wire harness organization relies on manual operation, which is labor-intensive and inefficient.

[0004] While existing high-lift gate hoists possess certain functionalities, practical applications suffer from cumbersome installation and disassembly of the rollers, resulting in low maintenance efficiency. Traditional gate hoist designs typically require operators to remove bolts to install or replace the rollers. This not only increases the operator's workload but also leads to long maintenance cycles and low efficiency. Because the operation involves multiple steps, negligence can easily lead to loose bolts or improper installation, posing a safety hazard and potentially causing equipment failure or accidents. Therefore, improving the efficiency of roller disassembly and installation while ensuring their stability has become a key technical challenge for enhancing equipment safety and operational efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-lift gate hoist with high safety, aiming to improve the traditional gate hoist design, which usually requires operators to install or replace the rollers by disassembling bolts. This not only increases the workload of operators, but also leads to long equipment maintenance cycles and low efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-lift gate hoist with high safety, comprising a fixed base, a bearing seat fixedly connected to the upper surface of the fixed base, a rotating shaft provided in the inner ring of the bearing seat, a positioning seat fixedly connected to the outer wall of the rotating shaft, a wire roller slidably connected to the outer wall of the positioning seat, a positioning block fixedly connected to the outer wall of the rotating shaft, and a disassembly and assembly component provided inside the positioning block;

[0008] Furthermore, a fixed support is fixedly connected to the upper surface of the fixed base, a rotating rod is rotatably connected inside the fixed support, an arc-shaped plate is fixedly connected to the outer wall of the rotating rod, a pressure roller is rotatably connected to one end of the arc-shaped plate, and a propulsion assembly is provided on the inner wall of the fixed support.

[0009] Furthermore, the propulsion assembly includes a torsion spring and a turntable, the turntable being fixedly connected to the outer wall of the rotating rod, and the fixed support containing the torsion spring.

[0010] Furthermore, a motor is fixedly connected to the upper surface of the fixed base, a transmission belt mechanism is provided at the output end of the motor, a reciprocating lead screw is provided at one end of the transmission belt mechanism, a wire seat is threadedly connected to the outer wall of the reciprocating lead screw, and a limit rod is slidably connected to the bottom of the wire seat.

[0011] Furthermore, both ends of the telescopic spring are fixedly connected to the outer wall of the block, and the telescopic spring is used to push the block to move.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a high-lift gate hoist with high safety, comprising a fixed base 1, a bearing seat 24 fixedly connected to the upper surface of the fixed base 1, a rotating shaft 4 provided in the inner ring of the bearing seat 24, a positioning seat 5 fixedly connected to the outer wall of the rotating shaft 4, a wire roller 6 slidably connected to the outer wall of the positioning seat 5, a positioning block 9 fixedly connected to the outer wall of the rotating shaft 4, and a disassembly and assembly component provided inside the positioning block 9.

[0027] The assembly / disassembly assembly includes a connecting seat 7 and a locking block 15, which slide within the positioning block 9 and the connecting seat 7 to facilitate the assembly / disassembly of the wire roller 6. The outer wall of the locking block 15 is slidably connected to the inside of the positioning block 9. One side of the outer wall of the connecting seat 7 is fixedly connected to the outer wall of the wire roller 6. A limit ring 8 is fixedly connected to the outer wall of the rotating shaft 4. A sliding sleeve 10 is slidably connected to the outer wall of the limit ring 8. Sliding along the outer wall of the limit ring 8 causes the slider 11 to move within the positioning block 9. The middle of the sliding sleeve 10 is fixedly connected to the slider 11. Its movement causes one end of the connecting rod 12 to move. The inner wall of the slider 11 is rotatably connected to the connecting rod 12. One end of the connecting rod 12 is connected to the slider 11, and the other end is connected to the locking block 15. One end of the connecting rod 12 is rotatably connected to the inside of the locking block 15. A telescopic rod 13 is fixedly connected to the outer wall of the locking block 15. A telescopic spring 14 is sleeved on the outer wall of the telescopic rod 13 to provide a rebound force, causing the locking block 15 to reset and achieve automatic fixing.

[0028] Specifically, the operator pulls the sliding sleeve 10, which causes the slider 11 to slide inside the positioning block 9. The movement of the slider 11 causes one end of the connecting rod 12 to move, which in turn causes the other end of the connecting rod 12 to move the locking block 15 inside the positioning block 9 and the connecting seat 7. This causes the locking block 15 to disengage from the connecting seat 7. At the same time, the telescopic spring 14 retracts. When the locking block 15 has completely moved into the positioning block 9, the wire roller 6 and the connecting seat 7 can be removed. The disassembly and assembly process is simple and efficient. During installation, simply put the connecting seat 7 back in its original position and then release the sliding sleeve 10. The rebound action of the telescopic spring 14 causes the locking block 15 to return to the connecting seat 7, thereby fixing the wire roller 6 and ensuring the stability of the installation.

[0029] Reference Figure 1 - Figure 4A fixed support 25 is fixedly connected to the upper surface of the fixed base 1. A rotating rod 16 is rotatably connected inside the fixed support 25. This rod, in conjunction with an arc-shaped plate 17, drives a pressure roller 18 to adhere to the outer wall of the wire harness. The arc-shaped plate 17 is fixedly connected to the outer wall of the rotating rod 16, assisting the movement of the pressure roller 18 and allowing it to adhere more tightly to the wire harness. One end of the arc-shaped plate 17 is rotatably connected to the pressure roller 18. Under the action of the rotating rod 16, pressure is applied to the wire harness, allowing it to tightly wrap around the outer wall of the roller 6, improving the finishing effect. A pushing assembly is provided on the inner wall of the fixed support 25. The pushing assembly includes a torsion spring 19 and a turntable 20, driving the rotating rod 16 to rotate. The turntable 20 is fixedly connected to the outer wall of the rotating rod 16. The torsion spring 19 is provided inside the fixed support 25, providing torque during the finishing process to rotate the turntable 20. A motor 2 is fixedly connected to the upper surface of the fixed base 1. After starting, it drives a transmission belt mechanism 3. A transmission belt mechanism 3 is provided at the output end of the motor 2. The reciprocating screw 21 and the rotating shaft 4 are driven to rotate at both ends. The reciprocating screw 21 is provided at one end of the transmission belt mechanism 3, which causes the wire seat 22 to move back and forth along the guide rod 23. The wire seat 22 is threadedly connected to the outer wall of the reciprocating screw 21. Under the drive of the reciprocating screw 21, it moves back and forth, thereby sorting the wire bundle and making it evenly wound around the outer wall of the wire roller 6. The bottom of the wire seat 22 is slidably connected to the guide rod 23, which provides a guide for the linear motion of the wire seat 22 and prevents deviation. Both ends of the telescopic spring 14 are fixedly connected to the outer wall of the locking block 15. The telescopic spring 14 is used to push the locking block 15 to move. The outer wall of the slider 11 is slidably connected to the inside of the positioning block 9. The slider 11 is used to drive one end of the connecting rod 12 to move. The outer wall of the locking block 15 is slidably connected to the inside of the positioning block 9 and the connecting seat 7. The locking block 15 is used to limit the connecting seat 7. One end of the torsion spring 19 is fixedly connected to the outer wall of the turntable 20, and the other end of the torsion spring 19 is fixedly connected to the inner wall of the fixed support 25.

[0030] Specifically, the motor 2 drives the transmission belt mechanism 3 to run, thereby driving the reciprocating screw 21 and the rotating shaft 4 to rotate. The reciprocating screw 21 and the wire seat 22 are connected by threads and guided by the limiting rod 23, so that the wire seat 22 can move back and forth along the reciprocating screw 21 to realize the automated arrangement of the wire harness and improve work efficiency. During the arrangement of the wire harness, the torsion spring 19 causes the turntable 20 to rotate, and the turntable 20 drives the rotating rod 16 to rotate, which in turn drives the arc plate 17, so that the other end of the arc plate 17 presses the pressure roller 18, making it fit against the outer wall of the wire harness, applying pressure to the wire harness, making it fit tightly against the outer wall of the roller 6, preventing the wire harness from loosening and improving the arrangement effect.

[0031] Working principle: When a high-lift gate hoist with high safety is required, firstly, pull the sliding sleeve 10 to slide on the outer wall of the limit ring 8, thereby driving the slider 11 to slide inside the positioning block 9. Then, the movement of the slider 11 drives one end of the connecting rod 12 to move, and then the other end of the connecting rod 12 drives the locking block 15 to slide inside the positioning block 9 and the connecting seat 7. At the same time, the telescopic spring 14 retracts. When the locking block 15 has completely moved into the positioning block 9, the wire roller 6 and the connecting seat 7 can be removed. During installation, first put the connecting seat 7 back in its original position, and then release the sliding sleeve 10. At this time, the rebound of the telescopic spring 14 drives the locking block 15 back into the connecting seat 7 to achieve fixation, thus achieving the effect of convenient disassembly and assembly of the wire roller 6.

[0032] In addition, the starter motor 2 drives the transmission belt mechanism 3 to run, thereby driving the reciprocating screw 21 and the rotating shaft 4 to rotate through the two ends of the transmission belt mechanism 3. Then, in conjunction with the thread relationship between the reciprocating screw 21 and the wire seat 22, and the guidance of the limit rod 23, the wire seat 22 is moved back and forth, which can arrange the wire harness to the outer wall of the wire roller 6. In addition, when arranging the wire harness, the torsion of the torsion spring 19 can drive the turntable 20 to rotate, thereby driving the rotating rod 16 to move through the turntable 20. Then, the rotation of the rotating rod 16, in conjunction with the arc plate 17, drives the pressure roller 18 to adhere to the outer wall of the wire harness, applying pressure to the wire harness so that the wire harness can be completely adhered to the outer wall of the wire roller 6.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
