Description

Technical Field

[0001] This utility model belongs to the field of gate technology, specifically relating to a gate lifting and lowering control device for hydraulic machinery equipment. Background Technology

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

[0003] The gate is raised and lowered by a lifting control device. However, when the gate is raised and lowered by the lifting control device, the gate is prone to shaking during the raising and lowering process due to the rope pulling the gate, which affects the stability of the gate during the raising and lowering process.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0027] Reference Figure 1-3 The above describes a gate lifting control device for hydraulic machinery, which includes a lifting control structure 1, and a sealing gate structure 2 is slidably connected inside the lifting control structure 1.

[0028] The lifting control structure 1 includes a mounting frame 101. A worm gear body 105 is rotatably connected to the top of the mounting frame 101. Transmission screws 107 are rotatably connected to both sides of the outer wall of the mounting frame 101. A synchronous belt drive device 108 is provided between the two transmission screws 107. A worm wheel body 106 is provided on the top of the transmission screw 107 on one side of the mounting frame 101, and the worm wheel body 106 meshes with the worm gear body 105. A placement groove 102 is provided inside the mounting frame 101. A sealing plate 103 is provided on the top of the inner wall of the placement groove 102. Two guide grooves 104 are provided on both sides of the inner wall of the placement groove 102. The height of one guide groove 104 is half the height of the placement groove 102, and the other... The height of the guide groove 104 is the same as the height of the placement groove 102. Side plates 109 are provided on both sides of the mounting frame 101. Bolt holes 110 are provided inside the side plates 109. The number of bolt holes 110 is set to multiple. The mounting frame 101 is installed into the water channel through the bolt holes 110. When the water channel needs to be opened, the motor is started. The motor drives the worm body 105 to rotate. The worm body 105 drives the worm wheel body 106 to rotate. The worm wheel body 106 drives the transmission screw 107 to rotate. The transmission screw 107 drives the transmission screw 107 on the other side to rotate through the synchronous belt transmission device 108, so that the transmission screw 107 drives the sealing gate structure 2 to slide inside the placement groove 102, thereby opening or closing the water channel.

[0029] Furthermore, in the above technical solution, the sealing gate structure 2 includes a first gate body 201 and a second gate 204. The first gate body 201 is slidably connected between the two guide grooves 104. A return spring 202 is provided between the first gate body 201 and the placement groove 102. An auxiliary groove 203 is provided on one side of the return spring 202. A guide strip 205 is provided on one side of the second gate 204. The guide strip 205 is slidably connected to the auxiliary groove 203. A mating hole 206 is provided on the other side of the second gate 204. The mating hole 206 and the transmission screw 107 cooperate with each other. The transmission screw 107 drives the second gate 204 to slide upward on the inner wall of the guide groove 104 through the mating hole 206. At the same time, the guide bar 205 slides on the inner wall of the auxiliary groove 203. When the guide bar 205 slides to the top of the auxiliary groove 203, the second gate 204 drives the first gate body 201 to slide on the inner wall of the guide groove 104. Then the first gate body 201 squeezes the reset spring 202. When the second gate 204 and the first gate body 201 are completely in contact, the placement groove 102 is fully opened.
