Description
Technical Field
[0001] This invention relates to the field of wire rope winding and unwinding devices, specifically a wire rope winding and unwinding device for a winch-type gate hoist in a hydropower station. Background Technology
[0002] A winch-type gate hoist is a specialized opening and closing device for operating fast-acting gates. Fast-acting gates are used to protect generator units or steel pipes. Normally suspended above the opening, they can quickly cut off water flow in case of accidents involving generators, pumps, or steel pipes, preventing the accident from escalating. Winch-type gate hoists in hydropower stations are typically installed in narrow spaces above ground, such as the hoist room or hoist frame. Furthermore, the wire ropes of winch-type gate hoists in medium to large-sized hydropower stations are thick and long. During operation and maintenance, space constraints make it inconvenient to disassemble and reassemble the wire ropes. Additionally, the lack of a limiting structure during rope winding and unwinding easily leads to uneven winding, affecting the lifespan of the wire rope and hindering timely detection of damage. Therefore, we propose a wire rope winding and unwinding device for winch-type gate hoists in hydropower stations. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a wire rope winding and unwinding device for a winch-type gate hoist in a hydropower station. The device uses a drive wheel and gear meshing to drive the winding wheel to wind and unwind the wire rope, which also facilitates subsequent disassembly and replacement. The wire rope pulley inside the fixed frame can limit the wire rope to prevent deviation during winding and unwinding. The industrial camera can detect the winding and unwinding of the wire rope, so that personnel can detect it in time. This can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a wire rope winding and unwinding device for a winch-type gate hoist in a hydropower station, comprising a base frame and a winding reel;
[0005] Base frame: Fixed seats are fixed on both sides of the top surface. The main motor is fixed on the outer side of the fixed seat. The output shaft of the main motor is connected to the outer side of the drive wheel. The outer side of the drive wheel is evenly provided with tooth grooves. Bearings are sleeved on both ends of the outer side of the take-up wheel. The bearings are engaged with the through grooves on the inner side of the fixed seat. A gear is fixed at the end of the take-up wheel. The gear meshes with the tooth grooves on the outer side of the drive wheel. A fixed post is provided on the front side inside the fixed seat. A first screw is threadedly connected to the screw hole inside the fixed post. The first screw is rotatably connected to the shaft hole on the top surface of the top cover. A limit frame is fixed on the inner side of the bottom surface of the top cover. A wire harness unit is provided inside the base frame. A stabilizing unit is provided on the outer side of the fixed seat. A cleaning unit is provided on the front side of the fixed seat.
[0006] The system also includes a controller, which is located on the front side of the base frame. The input terminal of the main motor is electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power supply.
[0007] The main motor is started, which drives the gear to mesh with the tooth groove on the outside of the drive wheel, thereby driving the winding wheel to wind up and unwind the wire rope. At the same time, the first screw is rotated to adjust the position of the top cover. The detachable winding wheel also makes it convenient for personnel to carry out maintenance and subsequent replacement.
[0008] Furthermore, the wire harness unit includes a support rod, a second screw, a placement slot, a motor, a fixing frame, a wire harness wheel, and a connecting seat. There are two placement slots, respectively located on the front and rear sides inside the base frame. The second screw is rotatably connected inside each placement slot. The motor is fixed to the left side of the base frame, and its output shaft is connected to the left end of the second screw. The end of the support rod is slidably connected to the placement slot, and the screw hole on the surface of the support rod is threadedly connected to the second screw. A fixing frame is fixed to the middle of the support rod. Connecting seats are fixed to both the left and right sides inside the fixing frame. A wire harness wheel is rotatably connected inside each connecting seat. The input end of the motor is electrically connected to the output end of the controller. Starting the motor drives the second screw to rotate, adjusting the position of the fixing frame. The wire harness wheel inside the fixing frame can limit the movement of the wire rope, ensuring that the wire rope is evenly wound around the outside of the take-up reel for subsequent use and to prevent misalignment.
[0009] Furthermore, the stabilizing unit includes a fixed disc, a limiting block, a support plate, a fixed shaft, an electric push rod, and a coupling. There are two electric push rods, fixed to the outer side of the fixed base in a front-to-back configuration. The inner end of each electric push rod is connected to one end of the outer side of the support plate. The support plate is located inside the fixed base. A through hole in the middle of the support plate is rotatably connected to the fixed shaft. The inner end of the fixed shaft is connected to the middle of the outer side of the fixed disc. A limiting block is fixed to the inner side of the fixed disc. A coupling is installed on the outer end of the fixed shaft. The input end of the electric push rod is electrically connected to the output end of the controller. Activating the electric push rod causes the limiting block on the inner side of the fixed disc to engage with the limiting groove on the outer side of the gear, thus preventing the gear from falling off. Simultaneously, when there is a malfunction in the wire rope winding or unwinding, the coupling can be connected to an external motor for use, thereby increasing the practicality of the device.
[0010] Furthermore, the cleaning unit includes a fixed housing, a spring, a fixed rod, a cleaning brush, and a bracket. There are two fixed housings, each fixed to the front side of a fixed base. A spring is fixed inside the fixed housing, and the front end of the spring is connected to one end of the rear side of the fixed rod. The fixed rod is slidably connected to the inside of the fixed housing. A bracket is fixed to the front side of the cleaning brush, and the bracket engages with a groove on the surface of the fixed rod. The bracket engages with the cleaning brush in the groove, and the spring retracts to automatically bring the cleaning brush into contact with the wire rope. This allows for cleaning during retraction and extension to prevent debris from adhering.
[0011] Furthermore, it also includes an industrial camera, a frame, and bolts. The bottom end of the frame is inserted into the groove on the top surface of the support rod. The bolts pass through the through holes on the side of the support rod and are threaded into the screw holes on the surface of the frame. An industrial camera is placed inside the frame. The input end of the industrial camera is electrically connected to the output end of the controller. The frame is fixed with bolts. The industrial camera inside the frame can detect the wire rope so that personnel can be notified in time to repair and replace it when the wire rope is damaged.
[0012] Furthermore, it also includes a dehumidifier box and a housing. The housing is fixed to the bottom surface of the top cover, and the dehumidifier box is slidably connected inside the housing. The desiccant inside the dehumidifier box can keep the inside of the mounting base dry to prevent the parts from getting damp and rusting.
[0013] Furthermore, it also includes a laser meter counter, which is fixed inside the rear side of the mounting frame. The output end of the laser meter counter is electrically connected to the input end of the controller. The laser meter counter can detect the length of the wire rope being wound up or down, thereby improving the accuracy of the wire rope winding up or down length.
[0014] Furthermore, it also includes two lighting lamps, which are fixed at both ends of the inner side of the frame. The input end of the lighting lamp is electrically connected to the output end of the controller. The lighting lamp can illuminate the surface of the wire rope, thereby improving the accuracy of the detection.
[0015] Furthermore, it also includes an audible and visual alarm, which is fixed to the top surface of the cover. The input of the audible and visual alarm is electrically connected to the output of the controller. The audible and visual alarm can flash an alarm when a problem is detected in the wire rope.
[0016] Furthermore, it also includes a wireless transmitter, which is fixed to the left side of the base frame. The output of the wireless transmitter is electrically connected to the input of the controller. The wireless transmitter can transmit the steel wire rope detection problem to the personnel in real time, so that the personnel can check it.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The wire rope winding and unwinding device for the winch-type gate hoist of this hydropower station has the following advantages:
[0018] 1. By starting the main motor, the gear meshes with the toothed groove on the outer side of the drive wheel, thereby driving the winding reel to wind up and unwind the wire rope. At the same time, rotating the first screw adjusts the position of the top cover. The detachable winding reel also facilitates maintenance and subsequent replacement.
[0019] 2. The position of the fixing frame is adjusted by starting the motor to drive the second screw to rotate. The wire rope pulley inside the fixing frame can limit the movement of the wire rope, so that the wire rope can be evenly wound on the outside of the winding wheel, which is convenient for subsequent use and also prevents the problem of mis-winding.
[0020] 3. By activating the electric push rod, the limiting block on the inner side of the fixed plate is engaged into the limiting groove on the outer side of the gear, thereby preventing the gear from falling off. At the same time, when there is a malfunction in the wire rope winding and unwinding, the coupling can be connected to an external motor for use, thereby increasing the practicality of the device.
[0021] 4. The cleaning brush is installed by inserting it into the slot using a clip. The spring retraction causes the cleaning brush to automatically engage with the wire rope, allowing for cleaning during both retraction and extension to prevent debris from adhering. The industrial camera inside the frame can detect the wire rope and promptly notify personnel for repair and replacement if damage occurs. Attached Figure Description

At the same time, the first screw 12 is rotated to adjust the position of the top cover 13. The detachable winding wheel 6 also facilitates maintenance and subsequent replacement. The system also includes an industrial camera 15, a frame 16, and bolts 17. The bottom end of the frame 16 corresponds to the groove on the top surface of the support rod 21. The bolt 17 is threaded through the through hole on the side of the support rod 21 and threaded into the screw hole on the surface of the frame 16.

Then, the main motor 9 is activated to drive the drive wheel 10 to mesh with the gear 8, so that the winding wheel 6 can wind and unwind the wire rope. The motor 24 is activated to drive the second screw 2. 2. Rotate to adjust the position of the fixing frame 25. The wire rope pulley 26 inside the fixing frame 25 can limit the wire rope, so that the wire rope can be evenly wound on the outside of the take-up pulley 6 for subsequent use, and it is not easy to cause the problem of winding misalignment. The spring 42 retracts to make the cleaning brush 44 automatically fit with the wire rope, so that it can clean it during take-up and take-up to prevent debris from adhering.
