Description

Technical Field

[0001] This utility model belongs to the field of water conservancy gate technology, and in particular relates to a winch opening and closing device for water conservancy gates. Background Technology

[0002] Gates are control facilities used to close and open water discharge channels. They are an important component of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, and discharge sediment and floating debris.

[0003] Patent document CN112064596B discloses an electrically operated hydraulic gate, including a gate frame and a gate plate. The left and right sides of the gate frame are respectively equipped with mounting plates for fixing the gate frame to the dam outlet. A fixing plate is welded to the top of the outer end face of the gate frame. An outer rod and an inner rod are welded to the right side of the top surface of the fixing plate. Lighting lamps are installed at the top of the outer rod and the inner rod.

[0004] The aforementioned application document describes a mechanism below the fixed plate that is fixed to the dam outlet using an installation plate, while the mechanism above the fixed plate is located on the dam. When the energized winch winds the rope upwards, it lifts the gate plate along the drop groove and guide groove. However, when the winch releases the rope to lower the gate, the bottom of the gate will collide with the bottom of the guide groove, which can easily damage the bottom of the gate. Therefore, this design needs improvement. Utility Model Content

[0005] The purpose of this invention is to provide a winch opening and closing device for hydraulic gates, which solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a winch opening and closing device for a hydraulic gate, comprising a gate frame and a mounting plate. The gate frame has an internal groove, and the gate body is slidably connected inside the groove. A bracket is fixedly connected to the top of the mounting plate, and a winding roller is rotatably connected to the inner side of the bracket. A motor is fixedly mounted on the side of the bracket, and a steel rope is wound around the surface of the winding roller. A guide wheel is provided on the top of the mounting plate. A buffer mechanism is provided inside the groove, and a sealing mechanism is provided at the bottom of the gate frame. The buffer mechanism includes a buffer plate and a groove. The buffer plate is slidably connected inside the groove, and a buffer spring and a vertical rod are fixedly connected to the bottom of the buffer plate. The end of the buffer spring away from the buffer plate is fixedly connected to the bottom of the groove. A connecting frame, a spring telescopic rod, and a limiting rod are fixedly connected to the side of the vertical rod. A contact plate is rotatably connected to the inner side of the connecting frame. The groove is located at the bottom of the groove, and a speed reduction block is fixedly connected to the inner wall of the groove.

[0008] Furthermore, the output shaft of the motor is fixedly connected to the winding roller, and the end of the steel rope away from the winding roller is fixedly connected to the top of the gate body. Turning on the motor can drive the winding roller to rotate, and when the winding roller rotates to wind up the steel rope, it will drive the gate body to rise.

[0009] Furthermore, a rubber pad is provided on the top of the buffer plate, and a total of six sets of buffer springs are provided. When the gate body falls, it will contact the top of the buffer plate, and the six sets of buffer springs will absorb the impact force.

[0010] Furthermore, the end of the contact plate away from the connecting frame is arc-shaped, and the end of the contact plate away from the connecting frame is close to the inner wall of the tank. When the contact plate moves downward, its arc-shaped end will contact the deceleration block on the inner wall of the tank.

[0011] Furthermore, the telescopic end of the spring telescopic rod is fixedly connected to the bottom of the contact plate, and the end of the limiting rod away from the vertical rod is close to the top of the contact plate. After the contact plate deflects, the spring telescopic rod will move back to its original position, and the limiting rod prevents the contact plate from deflecting upward.

[0012] Furthermore, the sealing mechanism includes a sealing airbag and an air chamber. The sealing airbag is fixedly connected to the inner bottom of the gate frame, and the air chamber is fixedly connected to the inner bottom of the slide groove. The piston inside the air chamber is slidably connected to a piston rod. A pressure plate is fixedly connected to the top of the piston rod, and a return spring is sleeved on the surface of the piston rod. A connecting pipe is fixedly connected through and to the side of the air chamber.

[0013] Furthermore, the two ends of the return spring abut against the bottom of the pressure plate and the top of the air chamber, respectively. The end of the connecting pipe away from the air chamber passes through and is fixedly connected to the bottom of the sealing airbag. When the buffer plate moves downward, causing the pressure plate to move downward, the return spring will be compressed.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, by setting up a buffer mechanism, achieves the effect of the gate body contacting the buffer plate when the motor drives the winding roller to rotate and release the steel rope, so that the gate body falls. At this time, the combination of the buffer plate, buffer spring, contact plate, deceleration block and other components will play a buffering and shock-absorbing effect on the gate body, preventing damage to the bottom of the gate body.

[0016] 2. This utility model, by setting a sealing mechanism, achieves the following: when the gate body falls, the sealing airbag is initially in a contracted state and will not affect the movement of the bottom of the gate body. When the bottom of the gate body contacts the buffer plate and drives the buffer plate to move downward, the sealing airbag will expand through the cooperation of components such as the pressure plate, piston rod, and air chamber. When the sealing airbag expands, it will seal the gap between the gate body and the slide groove, thereby improving the overall sealing performance.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A bracket 5 is fixedly connected to the top of the mounting plate 4, and a winding roller 6 is rotatably connected to the inner side of the bracket 5. A motor 7 is fixedly mounted on the side of the bracket 5, and a steel rope 8 is wound around the surface of the winding roller 6. A guide wheel 9 is provided at the top of the mounting plate 4. A buffer mechanism 10 is provided inside the groove 2, and a sealing mechanism 11 is provided at the bottom of the gate frame 1. The buffer mechanism 10 includes a buffer... Plate 102 and trough 108, buffer plate 102 is slidably connected inside the slide 2, buffer spring 101 and vertical rod 103 are fixedly connected to the bottom of buffer plate 102, the end of buffer spring 101 away from buffer plate 102 is fixedly connected to the bottom of the slide 2, connecting frame 104, spring telescopic rod 106 and limiting rod 107 are fixedly connected to the side of vertical rod 103, contact plate 105 is rotatably connected to the inner side of connecting frame 104, trough 108 is opened at the bottom of the slide 2, and deceleration block 109 is fixedly connected to the inner wall of trough 108.

[0029] As shown in the figure, the output shaft of the motor 7 is fixedly connected to the winding roller 6, and the end of the steel rope 8 away from the winding roller 6 is fixedly connected to the top of the gate body 3. When the motor 7 is turned on, the winding roller 6 can be driven to rotate. When the winding roller 6 rotates to wind up the steel rope 8, it will drive the gate body 3 to rise.

[0030] As shown in the figure, a rubber pad is provided on the top of the buffer plate 102, and a total of six sets of buffer springs 101 are set. When the gate body 3 falls, it will contact the top of the buffer plate 102, and the six sets of buffer springs 101 will absorb the impact force.

[0031] As shown in the figure, the end of the contact plate 105 away from the connecting frame 104 is arc-shaped, and the end of the contact plate 105 away from the connecting frame 104 is close to the inner wall of the tank 108. When the contact plate 105 moves downward, its arc-shaped end will contact the deceleration block 109 on the inner wall of the tank 108.

[0032] As shown in the figure, the telescopic end of the spring telescopic rod 106 is fixedly connected to the bottom of the contact plate 105, and the end of the limiting rod 107 away from the vertical rod 103 is close to the top of the contact plate 105. After the contact plate 105 deflects, the spring telescopic rod 106 will be driven to return to its original position. The limiting rod 107 prevents the contact plate 105 from deflecting upward.

[0033] As shown in the figure, the sealing mechanism 11 includes a sealing airbag 111 and an air chamber 112. The sealing airbag 111 is fixedly connected to the bottom inside of the gate frame 1, and the air chamber 112 is fixedly connected to the bottom inside of the slide groove 2. The piston inside the air chamber 112 is slidably connected to a piston rod 113. A pressure plate 114 is fixedly connected to the top of the piston rod 113, and a return spring 115 is sleeved on the surface of the piston rod 113. A connecting pipe 116 is fixedly connected through and to the side of the air chamber 112.

[0034] As shown in the figure, the two ends of the return spring 115 abut against the bottom of the pressure plate 114 and the top of the air chamber 112, respectively. The end of the connecting pipe 116 away from the air chamber 112 passes through and is fixedly connected to the bottom of the sealing airbag 111. When the buffer plate 102 moves downward and drives the pressure plate 114 to move downward, the return spring 115 will be compressed.

[0035] A specific application of this embodiment is as follows: The entire device is installed, and the motor 7 is turned on to drive the winding roller 6 to rotate. When the winding roller 6 rotates to wind up the steel rope 8, it can drive the gate body 3 upwards. When the winding roller 6 rotates to release the steel rope 8, it can cause the gate body 3 to descend. The guide wheel 9 acts as a guide. When the winding roller 6 rotates to release the steel rope 8 and causes the gate body 3 to descend, the bottom of the gate body 3 will first contact the top of the buffer plate 102 and drive the buffer plate 102 to move downwards. At this time, the six sets of buffer springs 101 will absorb the impact force and gradually be compressed. Simultaneously, the downward movement of the buffer plate 102 will also drive the vertical rod 103 to move downwards. The downward movement of the vertical rod 103 will drive the contact plate 105 to move downwards, and its arc-shaped end will contact the deceleration block 109. At this time, the contact plate 105 cannot deflect upwards and will be squeezed against the rubber semi-cylindrical deceleration block 109, generating significant resistance. Through resistance and... The buffer spring 101 provides a better buffering effect. When the buffer spring 101 rebounds, the buffer plate 102 moves upward, and the contact plate 105 contacts the deceleration block 109 again. At this time, the contact plate 105 will deflect and will not squeeze the deceleration block 109 too much. The resistance generated in this process is small, which can reduce the rebound amplitude of the buffer spring 101 and prevent the gate body 3 from moving up and down. At first, the sealing airbag 111 is in a contracted state and will not affect the movement of the bottom of the gate body 3. When the buffer plate 102 moves downward, it drives the pressure plate 114 to move downward, and the reset spring 115 is compressed. The downward movement of the pressure plate 114 will drive the piston rod 113 to move downward. The downward movement of the piston rod 113 will transport the air pressure in the air chamber 112 to the sealing airbag 111 through the connecting pipe 116. At this time, the sealing airbag 111 expands to seal the gap between the gate body 3 and the slide groove 2, improving the overall sealing performance.
