Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of winch hoist, in particular to a winch hoist. BACKGROUND

[0002] The winch hoist is commonly used in water conservancy gate, power plant inlet and other occasions, and its basic structure usually includes a motor, a speed reducer, a winding drum, a steel wire rope and the like. The winding drum is driven to rotate by the motor, so as to realize the winding and unwinding of the steel wire rope, thereby driving the gate to rise and fall. In the prior art, although such equipment has simple structure and high transmission efficiency, the following technical problems still exist in the long-term operation process: Conventional winches usually use smooth winding drums to wind the ropes, and lack effective limiting guide and spiral guide groove design, which leads to the overlapping, mispositioning and slot jumping of the cables, and in severe cases, may cause cable jamming and even equipment damage, affecting the accuracy and safety of the hoisting action. The traditional system generally lacks real-time collection and intelligent analysis means for the motor load, winding drum speed and other operating parameters, so that problems such as structural aging and poor lubrication are difficult to be found in time, and maintenance relies on manual regular inspection, which has reaction lag and hidden faults. Although some devices introduce a rope arranging device, they are mostly based on mechanical limiting method, lack real-time checking means for the rope arranging result, and cannot determine whether the cable is accurately arranged in the groove, which may cause false normal state and affect the winding quality and gate synchronization of the system. The guide mechanism is mostly a passive structure or a preset program control, and cannot be dynamically adjusted when the cable winding and unwinding speed fluctuates, lacks linkage feedback mechanism with the winding drum rotation state, and affects the guide accuracy and matching of the cable arrangement. The existing winch hoist with the publication number CN106629444A simply and effectively avoids dust adsorption on the surface of the steel cable through a dust cover, effectively solves the problem of dust agglomeration affecting the normal operation of the hoist, and reduces the failure caused by dust agglomeration during the winding and unwinding process of the steel cable, but cannot completely solve the above problems in a long time use. Therefore, a new type of winch hoist with reasonable structure, accurate detection and intelligent control is needed, which can realize automatic and orderly winding and unwinding of the cable, and has the functions of key component state monitoring, rope arrangement accuracy checking and dynamic adjustment of the guide path, so as to improve the operation safety and intelligent maintenance level of the system.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a winch-type gate hoist, comprising a fixed frame 1, a control module 2 is provided on the upper side of the fixed frame 1, a first motor 3 is fixedly connected to the right side of the upper surface of the fixed frame 1, a detection module 4 is provided on the outer wall of the first motor 3, a reducer 5 is provided at the output end of the first motor 3, the input end of the reducer 5 is fixedly connected to the output end of the first motor 3, a transmission assembly 6 is provided at the output end of the reducer 5, a roller 7 is fixedly connected to the output side of the transmission assembly 6, the front end outer wall of the roller 7 is rotatably connected to a bracket 8 through a bearing, and the lower side of the bracket 8 is fixedly connected to the upper surface of the fixed frame 1 , two steel cables 9 are fixedly connected to the outer wall of the roller 7, and the steel cables 9 are wound around the outer side of the roller 7. An anti-deviation mechanism 10 is provided on the upper side of the roller 7, and 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, and the guide mechanism 13 is used to limit the lower end of the steel cable 9. A threaded groove is provided on the outer wall of the roller 7, and the steel cable 9 is located inside the threaded groove. The threaded groove is used to position the steel cable 9 when it is reeled in, and the lower end of the steel cable 9 extends to the lower side of the fixed frame 1, and the end of the steel cable 9 located on the outside of the roller 7 is fixedly connected to the outer wall of the roller 7 by a bolt. This embodiment is to complete the winding and unwinding functions of the steel cable 9, and the specific working principle is as follows: The control module 2 issues an opening and closing command to control the first motor 3 to start running, and its real-time running status is monitored by the detection module 4. The output power of the first motor 3 is transmitted to the reducer 5, and after deceleration, the roller 7 is driven to rotate through the transmission component 6. The outer wall of the roller 7 is provided with a thread groove, and two steel cables 9 are wound around it and embedded in the thread groove. With the help of this structure, the steel cables 9 can be wound in an orderly manner to prevent overlapping and slipping; During the winding process, the anti-deviating mechanism 10 located above the roller 7 is used to detect the spacing between each turn of the steel cable 9 to avoid stacking misalignment; The lower end of the steel cable 9 extends through the guide mechanism 13, and the position of the steel cable 9 is limited and guided by its internal structure, so that the steel cable 9 can smoothly enter or leave the winding area. The whole process realizes stable and efficient retraction and release of the steel cable 9; By providing a first motor 3, a reducer 5, a transmission assembly 6 and a roller 7, the steel cable 9 is driven to be wound and unwound. Combined with the anti-deviance mechanism 10 to detect the spacing between the steel cables 9 and the guide mechanism 13 to guide the steel cables 9, it is ensured that the steel cables 9 run stably and are arranged in an orderly manner, providing a reliable basic support for the opening and closing of the system.

[0019] Example 2: Please refer to Figure 1-4 Based on the first embodiment, 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. The outer wall of the bracket 8 is fixedly connected to the connecting frame 11, and the middle part of the connecting frame 11 is fixedly connected to the angle encoder 12.

The angle encoder 12 is electrically connected to the control module 2; During the operation of the device, the detection module 4 samples the power changes and output speed of the first motor 3 in real time, and transmits the data 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 roller 7, and also transmits the data back to the control module 2 synchronously. The control module 2 compares the operating data of the first motor 3 and the roller 7. If it is found that the power increases but the speed decreases or the roller 7 rotates unevenly, it may be due to structural wear, component blocking, insufficient lubrication and other problems. 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 roller 7 decreases, it may be due to aging of the first motor 3, which makes it easier to detect hidden dangers in advance and effectively improve the safety and service life of the entire machine. By providing a detection module 4 and an angle encoder 12, the power and speed data of the first motor 3 and the roller 7 during operation are collected, and 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 of the system operation status and fault warning.

[0020] Example 3: Please refer to Figure 1-6On the basis of embodiment 1 and embodiment 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 through a bearing, the front end of the first bidirectional screw 101 is provided with a second motor 103, 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 first bidirectional screw 101 The outer wall of the screw 101 is threadedly connected, 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 hinged frame 106, the inner wall of the hinged frame 106 is hinged with a rotating rod 107 through a torsion spring, the outer wall of the rotating rod 107 is fixedly connected to a 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, and the lower end of the conductive block 108 is tilted toward the middle of the roller 7. The first bidirectional screw 101 is a bidirectional screw, and two groups of moving blocks 104, processing modules 105, hinged frames 106, rotating rods 107, and conductive blocks 108 are arranged on the outer side of the first bidirectional screw 101. The two groups of structures move in opposite directions, and the two conductive blocks 108 are both facing the middle of the roller 7; After the steel cable 9 has completed partial winding, the angle encoder 12 monitors the rotation angle of the roller 7. At the same time, the control module 2 starts the second motor 103, driving the first bidirectional screw 101 to rotate, thereby pushing the moving block 104 located outside the first bidirectional screw 101 to move linearly. The moving block 104 drives the rotating rod 107 through the articulated frame 106, and then drives the conductive block 108 to move toward the middle of the roller 7. Since the steel cable 9 is wound around the outside of the roller 7 at regular intervals, when the lower end of the conductive block 108 touches the surface of the steel cable 9 during movement, a current path is formed at the moment of contact with the outer wall of each turn. 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 misaligned or not embedded and needs to be rewound or corrected. By providing a second motor 103, a moving block 104, a processing module 105 and a conductive block 108, electrical contact detection of the actual entry of the steel cable 9 into the groove is achieved during the winding process of the steel cable 9, and the processing module 105 compares the path frequency and the moving speed to determine whether the steel cable 9 is accurately received in the threaded groove, thereby improving the rope arrangement accuracy.

[0021] Example 4: Please refer to Figure 1-6 On the basis of the first, second and third embodiments, the present invention provides a technical solution: during the winding process of the steel cable 9, since it has a spiral shape and continuously rotates with the roller 7, at this time, 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 contact point changes with the rotation position of the steel cable 9, the contact can be stable because the outer wall of the steel cable 9 is continuous and uniform; At the same time, the processing module 105 monitors in real time whether the current path persists and continuously sends the contact status to the control module 2; the control module 2 also synchronously 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 be determined 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 any jamming, jumping or sensor deviation. If an abnormal duration or synchronization error is detected, the system will prompt sensor drift or structural error, thereby realizing the verification and compensation of the accuracy of the detection system itself; 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 path continuity and the rotation rate to achieve self-inspection of the driving stability of the second motor 103 and the sensing accuracy of the angle encoder 12, thereby ensuring long-term and reliable operation of the sensing system.

[0022] Example 5: Please refer to Figure 1-6On the basis of the first, second, third and fourth embodiments, the present invention provides a technical solution: the guide mechanism 13 includes a third motor 301, the outer wall of the third motor 301 is fixedly connected to the outer wall of the fixing frame 1, the output end of the third motor 301 is fixedly connected to the second bidirectional threaded rod 302, the other end of the second bidirectional threaded rod 302 is rotatably connected to the connecting block 303 through a bearing, the upper end of the connecting block 303 is fixedly connected to the lower surface of the fixing frame 1, the outer wall of the connecting block 303 is fixedly connected to the second limiting rod 304, the outer side of the second bidirectional threaded rod 302 and the second limiting rod 304 is provided with a guide block 305, 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 running through it from top to bottom, and the steel cable 9 is located inside the circular hole; When the steel cable 9 is being wound by the roller 7, in order to ensure that it enters the thread groove smoothly and is arranged neatly, a guide mechanism 13 is used in conjunction with the steel cable 9. The third motor 301 is controlled by the control module 2 to drive the second bidirectional threaded rod 302 to rotate, thereby driving the guide block 305 sleeved on the outside thereof to move left and right. The steel cable 9 passes through the through hole opened on the inner wall of the guide block 305 and enters the thread groove on the surface of the roller 7 under its guidance. In order 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 result of the angle encoder 12 in real time, compare the current position of the steel cable 9 in the thread groove with the theoretical trajectory, and determine whether there is a deviation. If it is found that the steel cables 9 are unevenly arranged or the position of the guide block 305 is deviated, the speed of the third motor 301 is automatically adjusted or the second bidirectional threaded rod 302 is reversed to correct the guiding path, and finally realize automatic adaptive winding path control and guiding deviation correction, thereby improving the winding quality of the steel cable 9 and the intelligence level of the system; The second bidirectional threaded rod 302 is driven to rotate by the third motor 301 to drive the guide block 305 to move, thereby achieving precise guidance of the winding path of the steel cable 9, and can be combined with the monitoring data in Example 4 to achieve dynamic correction and deviation correction, thereby improving the automatic arrangement accuracy of the steel cable 9 and the overall winding quality.

[0023] The present invention provides a winch-type gate hoist, which is provided with a first motor 3, a reducer 5, a transmission assembly 6 and a roller 7, and cooperates with the roller 7 wound with a steel cable 9 and provided with a thread groove to achieve stable retraction and extension of the steel cable 9; the detection module 4 and the angle encoder 12 are used to synchronously collect the operating status of the first motor 3 and the rotation status of the roller 7, and the control module 2 performs data comparison and analysis, which can determine the degree of structural aging and operational abnormalities; further provided with an electrical contact detection structure composed of a second motor 103, a moving block 104, a processing module 105, and a conductive block 108, during the reeling process of the steel cable 9, whether the steel cable 9 is accurately embedded in the thread groove is detected in real time, thereby improving the rope arrangement accuracy; at the same time, a guide mechanism composed of a third motor 301, a second bidirectional threaded rod 302 and a guide block 305 is used to realize dynamic control of the path of the steel cable 9, and guide adjustment and sensor self-test are performed in combination with the above-mentioned detection results, ultimately realizing multiple functions of automatic and orderly retraction and extension of the steel cable 9, structural operation status perception, reeling accuracy verification and adaptive correction of the sensing system, thereby improving the automation level and operational reliability of the system.
