Description

Technical Field

[0001] This utility model relates to the field of hoisting gate hoisting technology, and in particular to a hoisting gate hoisting machine used for water conservancy interception of waterways. Background Technology

[0002] In the field of water conservancy engineering, hydraulic structures such as locks and dams typically require the use of hoist gate hoists, an important piece of equipment. This equipment is mainly responsible for the critical task of lifting and inspecting gates, and its applications include multiple stages such as equipment installation and commissioning, regular inspection and maintenance, and emergency repairs for sudden failures.

[0003] Traditional hoisting gates typically employ a motor-driven single-screw structure. The motor rotates the screw, and transmission is achieved through the threaded engagement between the screw and the gate, thereby controlling the gate's lifting and lowering movements. However, because power is provided by a single-sided screw, the gate is prone to eccentric forces during lifting, leading to uneven stress on both sides of the gate. This can cause problems such as gate tilting and jamming, affecting the stability and reliability of its operation. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, which relies on a single-sided screw to provide power, the gate is prone to eccentric force during the lifting process, resulting in uneven force on both sides of the gate. Therefore, this invention proposes a suspended gate hoist for water conservancy interception channels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A suspended gate hoist for water conservancy interception includes a base and a gate for opening and closing located above the base. A top plate is fixedly connected to the top of the base, and a pair of sliders are horizontally slidably connected to the top plate. A top block is fixedly connected to the top of the gate at the horizontal middle position. The sliders and the top block are rotatably connected to the same traction rod on opposite sides.

[0007] Also includes:

[0008] A drive assembly is disposed on the top plate, which drives the two sliders to move synchronously horizontally relative to each other or in opposite directions.

[0009] Preferably, the drive assembly includes a bidirectional lead screw rotatably connected to the top plate, both sliders being threadedly connected to the bidirectional lead screw, and a motor for driving the bidirectional lead screw to rotate is fixedly connected to the top plate.

[0010] Preferably, the top plate has a limiting groove that facilitates the horizontal sliding connection between the slider and the top plate.

[0011] Preferably, the slider and the top block are each fixedly connected to a pair of connecting ears on their opposite sidewalls, and the ends of the two traction rods away from the slider are hinged to the connecting ears on the top of the same top block, and the other ends of the two traction rods are respectively hinged to the connecting ears on the corresponding sliders.

[0012] Preferably, a pair of rectangular rods are fixedly connected to the top plate, and a pair of blocks are fixedly connected to the opening and closing gate, with the rectangular rods and the blocks being vertically slidably inserted into each other.

[0013] Preferably, the gate is provided with a cleaning assembly for cleaning impurities. The cleaning assembly includes a bottom groove 1 and a bottom groove 2 respectively opened at the bottom end of the gate. A cleaning roller is rotatably connected in the bottom groove 2, and a motor 2 for driving the cleaning roller to rotate is fixedly connected in the bottom groove 1.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] This invention, through the configuration of the drive assembly, enables the motor to rotate the bidirectional lead screw when the gate needs to be lowered. Because the two sliders are precisely threaded with the lead screw and constrained by the rigidity of the slot, the two sliders achieve high-precision synchronous horizontal movement towards each other, thereby driving the gate to descend vertically along the rectangular rod. This ensures that the gate experiences completely balanced forces on both sides during lifting and lowering, resulting in smooth and reliable gate operation, improved operational coordination, and extended overall service life of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-3 A type of hoist for water conservancy interception includes a base 1 and a gate 3 installed above the base 1. A top plate 2 is fixedly connected to the top of the base 1. A pair of sliders 32 are horizontally slidably connected to the top plate 2. A top block 33 is fixedly connected to the top of the gate 3 at the horizontal middle position. The sliders 32 and the top block 33 are rotatably connected to the same traction rod 36 on opposite sides. Under the action of the two traction rods 36, the gate 3 moves stably vertically.

[0026] Also includes:

[0027] The drive component is set on the top plate 2. The drive component drives the two sliders 32 to move synchronously in opposite directions or in the opposite direction.

[0028] The drive assembly includes a bidirectional lead screw 31 rotatably connected to the top plate 2, and two sliders 32 threadedly connected to the bidirectional lead screw 31. A motor 34 for driving the bidirectional lead screw 31 to rotate is fixedly connected to the top plate 2. The motor 34 drives the bidirectional lead screw 31 to rotate, and the bidirectional lead screw 31 drives the two sliders 32 to move synchronously horizontally relative to each other or in opposite directions. The movement is transmitted through two traction rods 36, realizing the vertical movement of the gate 3 for opening and closing.

[0029] The top plate 2 is provided with a limiting groove 37 to facilitate the horizontal sliding connection between the slider 32 and the top plate 2. The limiting groove 37 ensures that the slider 32 moves stably horizontally along the axis of the bidirectional lead screw 31.

[0030] Both the slider 32 and the top block 33 have paired connecting ears 35 fixedly connected to their opposite sidewalls. The ends of the two traction rods 36 away from the slider 32 are hinged to the connecting ears 35 on the top of the same top block 33, and the other ends of the two traction rods 36 are respectively hinged to the connecting ears 35 on the corresponding slider 32. The traction rods 36 rotate through the hinges, thereby realizing motion transmission.

[0031] A pair of rectangular rods 41 are fixedly connected to the top plate 2, and a pair of blocks 4 are fixedly connected to the gate 3, with the rectangular rods 41 and blocks 4 vertically slidably inserted.

[0032] The gate 3 is equipped with a cleaning assembly for removing debris. This assembly includes two grooves, a first groove 5 and a second groove 51, respectively located at the bottom of the gate 3. A cleaning roller 52 is rotatably connected to the second groove 51, and a second motor 53 for driving the cleaning roller 52 is fixedly connected to the first groove 5. The cleaning assembly is designed to prevent debris or rocks from obstructing the gate 3's descent as it approaches the bottom, thus preventing gaps between the gate 3 and the bottom and ensuring effective flood control. After removing debris or rocks, the gate 3 continues to descend until it is flush with the bottom. At this point, the cleaning roller 52 is pressed into the mud at the bottom and does not impede the gate 3's descent.

[0033] The functional principle of this utility model can be explained through the following operation methods:

[0034] When the gate 3 needs to be lowered, the motor 34 starts and drives the bidirectional screw 31 to rotate. Because the two sliders 32 are threadedly connected to the bidirectional screw 31 and are limited by the limiting groove 37, the two sliders 32 move horizontally relative to each other in sync. The top block 33 is pulled down by the traction rod 36, which drives the gate 3 to descend vertically along the rectangular rod 41. The sliding insertion structure between the rectangular rod 41 and the block 4 ensures that the gate 3 rises and falls smoothly.

[0035] When the gate 3 is descending and is about to reach the bottom of the water, in order to prevent the rocks or garbage at the bottom of the water from obstructing the gate 3 from continuing to descend, resulting in a gap between the gate 3 and the bottom of the water, which would affect the effectiveness of the gate 3 in preventing water flow; the second motor 53 is started, which drives the cleaning roller 52 to rotate and sweep the garbage or rocks away from the bottom of the gate 3.

[0036] After sweeping away stones or garbage, the gate 3 continues to descend until it is flush with the bottom of the water. At this time, the sweeping roller 52 is squeezed into the mud at the bottom of the water.

[0037] When it is necessary to lift the gate 3, the motor 34 rotates in the opposite direction, and the two sliders 32 move in opposite directions horizontally in sync, which can realize the lifting of the gate 3.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
