Description

Technical Field

[0001] This invention relates to the field of winch-type gate hoists, specifically to a winch-type gate hoist. Background Technology

[0002] Winch-type gate hoists are commonly used opening and closing devices in applications such as water conservancy gates and power station intakes. Their basic structure typically includes a motor, a reducer, a drum, and a wire rope. The motor drives the drum to rotate, thereby winding and unwinding the wire rope, which in turn drives the gate to rise and fall.

[0003] Although existing equipment has a simple structure and high transmission efficiency, the following technical problems still exist during long-term operation:

[0004] Conventional winches mostly use smooth drums to wind up the rope, lacking effective limit guidance and spiral guide groove design, which makes the cable prone to overlapping, misalignment, and jumping out of the groove. In severe cases, it may cause the rope to jam or even damage the equipment, affecting the accuracy and safety of the opening and closing action.

[0005] Traditional systems generally lack real-time acquisition and intelligent analysis of operating parameters such as motor load and drum speed, making it difficult to detect problems such as structural aging and poor lubrication in a timely manner. Maintenance relies on regular manual inspections, which results in delayed response and potential faults.

[0006] Although some equipment has introduced rope-laying devices, they are mostly based on mechanical limit methods and lack real-time verification of the rope-laying results. They cannot determine whether the cable has accurately entered the groove, which can easily lead to false normal states and affect the winding quality and gate synchronization of the system.

[0007] The guiding mechanism is mostly a passive structure or a preset program control, which cannot be dynamically adjusted when the cable winding and unwinding speed fluctuates. It lacks a linkage feedback mechanism with the drum rotation state, which affects the guiding accuracy and the matching of the cable arrangement.

[0008] There is a hoist-type gate opener with publication number CN106629444A. This device uses a dust cover to simply and effectively prevent dust from adsorbing on the surface of the steel cable, which effectively solves the problem of dust caking affecting the normal operation of the gate opener. It can reduce the failure caused by dust caking during the winding and unwinding of the steel cable. However, it cannot completely solve the above problems during long-term use.

[0009] Therefore, there is an urgent need for a new type of winch-type gate hoist with a reasonable structure, accurate detection, and intelligent control, which can realize the automatic and orderly winding and unwinding of cables, and at the same time have functions such as key component status monitoring, rope arrangement accuracy verification, and dynamic adjustment of guide path, thereby improving the system's operational safety and intelligent maintenance level.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a winch-type gate opener, comprising a fixed frame 1, a control module 2 disposed on the upper side of the fixed frame 1, a first motor 3 fixedly connected to the right side of the upper surface of the fixed frame 1, a detection module 4 disposed on the outer wall of the first motor 3, a reducer 5 disposed at the output end of the first motor 3, the input end of the reducer 5 fixedly connected to the output end of the first motor 3, a transmission assembly 6 disposed at the output end of the reducer 5, a rotating roller 7 fixedly connected to the output side of the transmission assembly 6, a bracket 8 rotatably connected to the front outer wall of the rotating roller 7 via a bearing, and the lower side of the bracket 8 fixedly connected to the upper surface of the fixed frame 1. Two steel cables 9 are fixedly connected to the outer wall of the rotating roller 7. The steel cables 9 are wound around the outside of the rotating roller 7. An anti-deviation mechanism 10 is provided on the upper side of the rotating roller 7. The anti-deviation mechanism 10 is used to detect the interval between each turn of the steel cable 9. A guide mechanism 13 is provided on the lower side of the fixed frame 1. The guide mechanism 13 is used to limit the lower end of the steel cable 9. A threaded groove is opened on the outer wall of the rotating roller 7. The steel cable 9 is located inside the threaded groove. The threaded groove is used to position the steel cable 9 when it is wound up. The lower end of the steel cable 9 extends to the lower side of the fixed frame 1. The end of the steel cable 9 located on the outside of the rotating roller 7 is fixedly connected to the outer wall of the rotating roller 7 by bolts.

[0036] This embodiment demonstrates the function of winding and unwinding steel cable 9. The specific working principle is as follows:

[0037] The control module 2 issues an opening and closing command to control the first motor 3 to start running, and the detection module 4 monitors its real-time running status. The first motor 3 outputs power to the reducer 5, and after deceleration, it drives the rotating roller 7 to rotate through the transmission component 6. The outer wall of the rotating roller 7 is provided with a threaded groove, and two steel cables 9 are wound around it and embedded in the threaded groove. With the help of this structure, the steel cables 9 can be wound in an orderly manner to prevent overlapping and slippage.

[0038] During the winding process, the anti-deviation mechanism 10 located above the rotating roller 7 is used to detect the spacing between each turn of the steel cable 9 to prevent stacking misalignment;

[0039] The lower end of the steel cable 9 extends through the guide mechanism 13, which limits and guides the position of the steel cable 9 with the help of its internal structure, so that the steel cable 9 can smoothly enter or leave the winding area. The whole process achieves stable and efficient winding and unwinding of the steel cable 9.

[0040] The system is equipped with a first motor 3, a reducer 5, a transmission assembly 6, and a rotating roller 7 to drive the winding and unwinding of the steel cable 9. Combined with the anti-deviation mechanism 10 to detect the spacing of the steel cable 9 and the guide mechanism 13 to guide the steel cable 9, the system ensures that the steel cable 9 runs stably and is arranged in an orderly manner, providing a reliable foundation for the system's opening and closing.

[0041] Example 2: Please refer to Figure 1-4 Based on Embodiment 1, the present invention provides a technical solution: the detection module 4 is electrically connected to the control module 2, and the detection module 4 is used to collect the real-time power consumption and speed of the first motor 3. A connecting frame 11 is fixedly connected to the outer wall of the bracket 8, and an angle encoder 12 is fixedly connected to the middle of the connecting frame 11. The input side of the angle encoder 12 is fixedly connected to the front end of the rotating roller 7, and the angle encoder 12 is used to detect the deflection of the rotating roller 7. The angle encoder 12 is electrically connected to the control module 2.

[0042] During the operation of the device, the power change and output speed of the first motor 3 are sampled in real time by the detection module 4 and the data is transmitted to the control module 2. At the same time, the angle encoder 12 is installed on the connecting frame 11 to detect the rotation angle and speed of the rotating roller 7 and also transmits the data back to the control module 2 synchronously.

[0043] The control module 2 compares the operating data of the first motor 3 and the rotating roller 7. If it finds that the power increases but the speed decreases or the rotating roller 7 rotates unevenly, there may be problems such as structural wear, component jamming, and insufficient lubrication. Based on this, the system can determine whether maintenance or replacement of parts is required. If the power of the first motor 3 remains unchanged but the speed of the rotating roller 7 decreases, the first motor 3 may be aging. This makes it easier to detect potential problems in advance and effectively improve the safety and lifespan of the whole machine.

[0044] By setting up a detection module 4 and an angle encoder 12, the power and speed data of the first motor 3 and the rotating roller 7 during the working process are collected. The control module 2 performs real-time comparison and analysis, which can intelligently identify structural aging, poor lubrication or potential faults, and realize health assessment and fault warning of the system's operating status.

[0045] Example 3: Please refer to Figure 1-6 Based on Embodiments 1 and 2, the present invention provides a technical solution: the anti-deviation mechanism 10 includes a first bidirectional screw 101, the outer wall of the first bidirectional screw 101 is rotatably connected to the outer wall of the bracket 8 via a bearing, a second motor 103 is provided at the front end of the first bidirectional screw 101, the second motor 103 is electrically connected to the control module 2, the output end of the second motor 103 is fixedly connected to the front end of the first bidirectional screw 101, a first limiting rod 102 is provided on the upper side of the first bidirectional screw 101, the outer wall of the first limiting rod 102 is fixedly connected to the outer wall of the bracket 8, a moving block 104 is provided on the outer side of the first bidirectional screw 101 and the first limiting rod 102, the upper side of the inner wall of the moving block 104 contacts the outer wall of the first limiting rod 102, and the lower inner wall of the moving block 104 contacts the outer wall of the first bidirectional screw 101. The outer wall of the screw 101 is threaded. The upper side of the moving block 104 is fixedly connected to the processing module 105. The lower side of the moving block 104 is fixedly connected to the hinge frame 106. The inner wall of the hinge frame 106 is hinged to the rotating rod 107 by a torsion spring. The outer wall of the rotating rod 107 is fixedly connected to the conductive block 108. The processing module 105 is electrically connected to the control module and the processing module 105 is electrically connected to the conductive block 108. The moving block 104 is made of insulating material. The lower end of the conductive block 108 is inclined towards the middle of the rotating roller 7. The first bidirectional screw 101 is a bidirectional screw. Two sets of moving blocks 104, processing modules 105, hinge frames 106, rotating rods 107, and conductive blocks 108 are arranged on the outer side of the first bidirectional screw 101. The two sets of structures move in opposite directions, and both conductive blocks 108 face the middle of the rotating roller 7.

[0046] After the steel cable 9 completes part of the winding, the angle encoder 12 monitors the rotation angle of the rotating roller 7. At the same time, the control module 2 starts the second motor 103, drives the first bidirectional screw 101 to rotate, and then pushes the moving block 104 located outside it to move linearly. The moving block 104 drives the rotating rod 107 through the hinge frame 106, and then drives the conductive block 108 to move towards the middle of the rotating roller 7.

[0047] Since the steel cable 9 is wound around the outside of the rotating roller 7 at regular intervals, when the lower end of the conductive block 108 touches the surface of the steel cable 9 during the movement, a current path will be formed at the moment of contact of each turn of the outer wall. The current forms a path through the processing module 105, the conductive block 108, the steel cable 9, and the gate assembly connected to the lower side of the steel cable 9 and the bottom surface. The processing module 105 controls the discharge and collects the frequency of the path formation and compares it with the moving speed of the moving block 104. If the pitch of the steel cable 9 corresponding to the frequency is consistent with the theoretical value, it indicates that the steel cable 9 is indeed embedded in the thread groove. Otherwise, it indicates that the steel cable 9 is not aligned or not embedded and needs to be rewound or corrected.

[0048] By incorporating a second motor 103, a moving block 104, a processing module 105, and a conductive block 108, the actual entry of the steel cable 9 into the groove is detected through electrical contact during the winding process. The processing module 105 compares the path frequency with the moving speed to determine whether the steel cable 9 is accurately stored in the threaded groove, thereby improving the rope routing accuracy.

[0049] Example 4: Please refer to Figure 1-6 Based on Embodiments 1, 2 and 3, the present invention provides a technical solution: During the winding process of the steel cable 9, since it has a spiral shape and rotates continuously with the roller 7, the second motor 103 is started by the control module, so that the second motor 103 drives the first bidirectional screw 101 to rotate, thereby driving the conductive block 108 to move. During this process, the lower end of the conductive block 108 maintains continuous contact with a point on the upper side of the steel cable 9. Although the position of the contact point changes with the rotation of the steel cable 9, the contact can be stably maintained because the outer wall of the steel cable 9 is continuous and uniform.

[0050] Meanwhile, the processing module 105 monitors in real time whether the current path continues to exist and continuously sends the contact status to the control module 2; the control module 2 also receives the rotation speed data of the roller 7 from the angle encoder 12. By comparing the two signals, namely the duration of electrical contact and the theoretical rotation speed of the roller 7, it can determine whether the movement of the moving block 104 driven by the second motor 103 is consistent with the movement trend of the steel cable 9, and whether there is jamming, jumping or sensor deviation. If an abnormal duration or synchronization error is detected, the system will prompt the sensor drift or structural error, thereby realizing the verification and compensation of the accuracy of the detection system itself.

[0051] By keeping the conductive block 108 in continuous contact with the rotating steel cable 9 during the winding process, and cooperating with the angle encoder 12 to monitor the rotation state of the roller 7, the control module 2 compares the continuity of the path with the rotation rate to achieve self-testing of the driving stability of the second motor 103 and the sensing accuracy of the angle encoder 12, ensuring the long-term reliable operation of the sensing system.

[0052] Example 5: Please refer to Figure 1-6Based on Embodiments 1, 2, 3, and 4, the present invention provides a technical solution: the guiding mechanism 13 includes a third motor 301, the outer wall of the third motor 301 is fixedly connected to the outer wall of the fixed frame 1, the output end of the third motor 301 is fixedly connected to a second bidirectional threaded rod 302, the other end of the second bidirectional threaded rod 302 is rotatably connected to a connecting block 303 through a bearing, the upper end of the connecting block 303 is fixedly connected to the lower surface of the fixed frame 1, the outer wall of the connecting block 303 is fixedly connected to a second limiting rod 304, a guide block 305 is provided on the outer side of the second bidirectional threaded rod 302 and the second limiting rod 304, the inner wall of the guide block 305 is slidably connected to the outer wall of the second limiting rod 304, and the inner wall of the guide block 305 is threadedly connected to the outer wall of the second bidirectional threaded rod 302, a circular hole is opened on the guide block 305 through the top and bottom, and the steel cable 9 is located inside the circular hole;

[0053] During the winding process of the steel cable 9 by the rotating roller 7, in order to ensure that it smoothly enters the thread groove and is neatly arranged, a guide mechanism 13 is required. The third motor 301 is controlled by the control module 2, which drives the second bidirectional threaded rod 302 to rotate, thereby driving the guide block 305 sleeved on its outside to move left and right. The steel cable 9 passes through the through hole opened in the inner wall of the guide block 305 and enters the thread groove on the surface of the rotating roller 7 under its guidance.

[0054] To further improve the guiding accuracy, the control module 2 will also receive the electrical contact information from the processing module 105 and the rotation detection results from the angle encoder 12 in real time. It will compare the current position of the steel cable 9 in the thread groove with the theoretical trajectory to determine whether there is a deviation. If the uneven distribution of the steel cable 9 or the position deviation of the guide block 305 is found, the speed of the third motor 301 will be automatically adjusted or the second bidirectional thread rod 302 will be reversed to correct the guiding path. In the end, the automatic adaptation of the winding path control and guiding correction will be achieved, thereby improving the winding quality of the steel cable 9 and the intelligence level of the system.

[0055] The second bidirectional threaded rod 302 is driven to rotate by the third motor 301, which in turn drives the guide block 305 to move, thereby achieving precise guidance of the winding path of the steel cable 9. Furthermore, dynamic correction and deviation correction can be achieved by combining the monitoring data in Embodiment 4, thereby improving the automatic arrangement accuracy of the steel cable 9 and the overall winding quality.

[0056] This invention provides a winch-type gate hoist, which, through the arrangement of a first motor 3, a reducer 5, a transmission component 6, and a rotating roller 7, works in conjunction with the rotating roller 7, which is wound with a steel cable 9 and has a threaded groove, to achieve stable winding and unwinding of the steel cable 9. The operating status of the first motor 3 and the rotation status of the rotating roller 7 are synchronously collected by a detection module 4 and an angle encoder 12, and the data is compared and analyzed by a control module 2 to determine the degree of structural aging and operational abnormalities. Furthermore, an electrical contact detection structure composed of a second motor 103, a moving block 104, a processing module 105, and a conductive block 108 is provided to detect in real time whether the steel cable 9 is accurately embedded in the threaded groove during the winding process, thereby improving the rope arrangement accuracy. At the same time, a guiding mechanism composed of a third motor 301, a second bidirectional threaded rod 302, and a guide block 305 realizes dynamic control of the path of the steel cable 9, and combines the aforementioned detection results to perform guiding adjustment and sensor self-checking. Ultimately, it realizes multiple functions such as automatic and orderly winding and unwinding of the steel cable 9, perception of structural operating status, verification of winding accuracy, and adaptive correction of the sensing system, thereby improving the automation level and operational reliability of the system.
