Description

Technical Field

[0001] This utility model relates to the field of gate locking, and in particular to a clamping structure and an electric operating tool for inspecting and maintaining the gate locking beam. Background Technology

[0002] When inspecting the gates in the control room of a hydropower plant, the gates need to be lifted to check their structure. The gates are equipped with locking beams. Before lifting the gates, the locking beams need to be released from the locked state so that the gates can be lifted by a crane. The locking beams are released from the locked state by rotating the valve disc of the locking beams by the operator, which moves the locking beams through chain drive, thereby unlocking the locking beams.

[0003] However, due to their considerable weight, existing locking beams often require multiple workers to work together to rotate the valve disc. This manual labor-intensive operation is not only physically demanding but also significantly reduces operational efficiency. Furthermore, the need for repeated coordination of the force exertion during multi-person operation makes it difficult to achieve rapid rotation of the valve disc, often resulting in excessively long preparation times for gate maintenance.

[0004] More importantly, during the process of multiple people applying force simultaneously, uneven force application can easily cause the valve disc to shift, which may lead to jamming of the chain drive mechanism or even wear of components. This not only increases the risk of equipment failure but also poses a threat to operational safety. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is that the existing locking beam unlocking fixture is difficult to connect with the valve disc quickly, which will delay the unlocking of the locking beam and affect the efficiency of unlocking the locking beam.

[0006] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a clamping structure, which includes a connector, including a connecting tube and a connecting hole opened on one side of the connecting tube;

[0007] An extrusion component, disposed on the outer wall of a connector, includes a movable tube disposed on the outer wall of the connecting tube, a fixed tube disposed on one side of the movable tube, and a threaded tube rotatably connected to one side of the movable tube.

[0008] A hook component, disposed on one side of a connector, includes a hook and a connecting end disposed on one side of the hook;

[0009] The movable tube can move along the outer wall of the connecting tube. When the movable tube moves along the outer wall of the connecting tube, the connecting member squeezes the hook and moves into the connecting member.

[0010] In a preferred embodiment of the clamping structure of this utility model: the outer wall of the connecting tube is threadedly connected to the inner wall of the threaded tube, and the inner wall of the fixed tube is slidably connected to the outer wall of the connecting tube.

[0011] In a preferred embodiment of the clamping structure of this utility model: a first opening is provided on one side of the connecting tube, the outer wall of the hook is slidably connected to the inner wall of the first opening, and a second opening is provided on one side of the fixing tube, the position of the second opening corresponds to the position of the first opening, and the inner wall of the second opening is slidably connected to the outer wall of the hook.

[0012] In a preferred embodiment of the clamping structure of this utility model: a squeezing end is provided on one side of the moving tube. When the moving tube moves along the outer wall of the connecting tube, the squeezing end will squeeze the outer wall of the hook during the movement. A pressing end is provided at one end of the fixed tube near the connecting end.

[0013] In a preferred embodiment of the clamping structure of this utility model: a movable end is provided on one side of the hook, and locking blocks are provided on both sides of the movable end; an inner cavity is provided on one side of the connecting tube; the movable end is disposed in the inner cavity and can slide in the inner cavity; the distance between the two locking blocks is greater than the length of the first opening; and an elastic element is provided between one side of the movable end and the inner wall of the inner cavity.

[0014] The beneficial effects of this utility model are as follows: the clamping structure uses a threaded tube to drive the moving tube to squeeze the hook, and works with the elastic element to achieve quick clamping and separation. The connection can be completed without disassembling the valve disc, which greatly improves the docking efficiency with the valve disc.

[0015] The technical problem to be solved by this utility model is that the existing unlocking method will delay the maintenance of the valve and may also cause the valve disc to shift under force, causing the chain drive mechanism to jam or even wear down the components.

[0016] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes an electric operating tool for the maintenance gate locking beam, which includes an installation component, including a movable frame, a fixed platform set in the middle of the movable frame, and a square tube set on the top of the fixed platform.

[0017] An operating component, disposed on the outer wall of the mounting component, includes a movable plate, a connecting pipe disposed on the top of the movable plate, and a threaded rod rotatably connected to the top of the connecting pipe; wherein...

[0018] When the threaded rod rotates, the movable plate can move along the square tube.

[0019] In a preferred embodiment of the electric operating fixture for the gate locking beam of this utility model: the outer wall of the moving plate is provided with bolts, and the moving plate is connected to a motor by bolts.

[0020] In a preferred embodiment of the electric operating fixture for the maintenance gate locking beam described in this utility model: the movable plate is fixed to the outer wall of the square tube by bolts.

[0021] In a preferred embodiment of the electric operating fixture for the gate locking beam of this utility model: a crossbeam is provided at the top of the movable frame, a support is provided on one side of the crossbeam, and the outer wall of the threaded rod is threadedly connected to the outer wall of the support.

[0022] In a preferred embodiment of the electric operating fixture for the maintenance gate locking beam described in this utility model: the bottom of the moving frame is provided with rollers.

[0023] The beneficial effects of this utility model are as follows: by replacing manual driving with an electric motor, the valve disc offset caused by uneven force exerted by multiple people is avoided. At the same time, the height of the motor can be adjusted by the threaded rod to adapt to different working conditions, which not only improves the unlocking stability but also enhances the operational flexibility.

[0037] Reference Figures 1-10 This embodiment provides an electric operating fixture for inspecting the gate locking beam, including,

[0038] The mounting component 2 includes a movable frame 21, a fixed platform 22 located in the middle of the movable frame 21, and a square tube 23 located on the top of the fixed platform 22. The movable frame 21 is a frame welded from several square tubes, with the fixed platform 22 connected to it by welding. The fixed platform 22 is a square frame welded from tubes, with a metal plate on it. Several square tubes 23 are welded onto the metal plate, and the square tubes 23 are perpendicular to the top of the fixed platform 22 and the movable frame 21, respectively.

[0039] It also includes an operating component 3, which is disposed on the outer wall of the mounting component 2, including a movable plate 31, a connecting pipe 32 disposed on the top of the movable plate 31, and a threaded rod 33 rotatably connected to the top of the connecting pipe 32; wherein, when the threaded rod 33 rotates, the movable plate 31 can move along the square tube 23.

[0040] It should be noted that a hinge is welded to the top of the connecting pipe 32, and a pivot is provided at the top of the hinge. The bottom of the threaded rod 33 passes through the middle of the pivot, and the threaded rod 33 can rotate on the pivot.

[0041] Bolts 34 are provided on the outer wall of the movable plate 31. The movable plate 31 is connected to the motor 35 through the bolts 34. When it is necessary to unlock the locking beam, the valve disc on the chain drive structure can be removed, and then the output end of the motor 35 and the drive shaft used to drive the chain drive structure can be connected through the connecting pipe. At this time, the motor 35 can drive the drive shaft to rotate, thereby driving the chain drive structure. This greatly reduces the time for unlocking the locking beam. At the same time, the drive shaft will not deviate when rotating, thus ensuring the stability of the chain drive structure during operation.

[0042] The movable plate 31 is fixed to the outer wall of the square tube 23 by bolts 34. It should be noted that the bolts 34 are long bolts, one side of which passes between the two square tubes 23 and is connected to a nut, so that the movable plate 31 is fixed on the square tube 23. When the movable plate 31 needs to be moved, the nut can be loosened to unlock the locked state of the movable plate 31, and then the movable plate 31 can be moved.

[0043] A crossbeam 24 is provided on the top of the movable frame 21, and a support 25 is provided on one side of the crossbeam 24. The outer wall of the threaded rod 33 is threadedly connected to the outer wall of the support 25. A nut that matches the threaded rod 33 is provided on the support 25. When the threaded rod 33 is rotated, it can move up and down. Therefore, after loosening the nut on the bolt 34, rotating the threaded rod 33 can drive the movable plate 31 to move up and down. This allows the height of the motor 35 to be changed to adapt to the position of different drive shafts.

[0044] The bottom of the mobile frame 21 is equipped with casters 26, which are universal casters. Four casters 26 are provided at the bottom of the mobile frame 21 to support the mobile frame 21, so that the operator can push the mobile frame 21 to move.

[0045] Reference Figures 1-8 This embodiment provides a clamping structure, including:

[0046] The connector 11 includes a connecting pipe 111 and a connecting hole 112 opened on one side of the connecting pipe 111. The connecting pipe 111 is a tubular structure, and a connecting hole 112 is opened on one side of it to connect with the output end of the motor 35. The connecting pipe 111 can be fixed to the output end of the motor 35 by bolts.

[0047] It also includes an extrusion member 12, which is disposed on the outer wall of the connector 11. It includes a movable tube 121 disposed on the outer wall of the connecting tube 111, a fixed tube 122 disposed on one side of the movable tube 121, and a threaded tube 123 rotatably connected to one side of the movable tube 121. The outer wall of the connecting tube 111 is threadedly connected to the inner wall of the threaded tube 123, and the inner wall of the fixed tube 122 is slidably connected to the outer wall of the connecting tube 111. When the threaded tube 123 is rotated, the threaded tube 123 will drive the movable tube 121 and the fixed tube 122 to move.

[0048] It should be noted that an annular groove is provided on the inner wall of one end of the movable tube 121, and a fixing ring is provided on the outer wall of one end of the threaded tube 123. The fixing ring is engaged in the annular groove, so that the threaded tube 123 is fixed to one end of the movable tube 121, and the threaded tube 123 can rotate autonomously relative to the movable tube 121.

[0049] It also includes a hook member 13, disposed on one side of the connector 11, including a hook 131 and a connecting end 132 disposed on one side of the hook 131. A first opening 114 is provided on one side of the connecting tube 111, and the outer wall of the hook 131 is slidably connected to the inner wall of the first opening 114. A second opening 125 is provided on one side of the fixing tube 122, the position of the second opening 125 corresponding to the position of the first opening 114, and the inner wall of the second opening 125 is slidably connected to the outer wall of the hook 131. Several hooks 131 are provided, and the first opening 114 and the second opening 125 are slidably connected to each other. The number of openings 125 corresponds to the number of hooks 131. When connecting the valve disc, the connecting end 132 of the hook 131 is passed through the upper hole of the valve disc, so that several hooks 131 surround the center point of the valve disc. Then, the threaded tube 123 is rotated, so that the moving tube 121 and the fixed tube 122 move. An inclined surface is provided at the end of the hook 131 near the moving tube 121. When the moving tube 121 moves, it will squeeze the inclined surface, so that the hook 131 moves into the connecting tube 111. In this way, the hook 131 will gradually contact the middle part of the valve disc.

[0050] A pressing end 124 is provided on one side of the moving tube 121. When the moving tube 121 moves along the outer wall of the connecting tube 111, the pressing end 124 will press the outer wall of the hook 131 during the movement. A pressing end 126 is provided on one end of the fixed tube 122 near the connecting end 132. In order to reduce the friction between the moving tube 121 and the hook 131, the pressing end 124 is provided. Its diameter is larger than the diameter of the moving tube 121 itself. At the same time, a rounded corner is provided on one side of the pressing end 124. When the moving tube 121 moves, the side of the pressing end 124 with the rounded corner will press the inclined surface of the hook 131, thereby reducing the wear of the hook 131.

[0051] Simultaneously, as the fixed tube 122 moves along the moving tube 121, it drives the pressing end 126 to move towards the connecting end 132. It should be noted that after the hook 131 passes through the hole on the valve disc, the connecting end 132 moves to the back of the valve disc. After the hook 131 contacts the middle part of the valve disc, the connecting end 132 can hook onto the back of the middle part of the valve disc. Therefore, when the pressing end 126 moves towards the connecting end 132, it will gradually approach the front of the middle part of the valve disc. When the fixed tube 122 continues to move, the pressing end 126 can press against the valve disc. At this time, the pressing end 126 and the connecting end 132 can clamp the valve disc, thus completing the work of connecting the valve disc to the output end of the motor 35. This eliminates the need to disassemble the valve disc and allows the connecting shaft to be connected to the motor 35, saving related steps and improving the efficiency of unlocking and locking the beam.

[0052] The movable tube 121 can move along the outer wall of the connecting tube 111. When the movable tube 121 moves along the outer wall of the connecting tube 111, the connecting member 11 squeezes the hook member 13 and moves it into the connecting member 11.

[0053] It should be noted that the structure of the valve disc is similar to that of a car steering wheel. It has a disc in the center that is connected to the connecting shaft, and several connecting rods are connected to the outside of the disc. Each of the connecting rods is connected to a ring.

[0054] As an optional embodiment, the hook 131 is self-resetting.

[0055] A movable end 133 is provided on one side of the hook 131, and locking blocks 134 are provided on both sides of the movable end 133. An inner cavity 113 is provided on one side of the connecting pipe 111. The movable end 133 is disposed in the inner cavity 113 and can slide in the inner cavity 113. The distance between the two locking blocks 134 is greater than the length of the first opening 114. An elastic element 135 is provided between one side of the movable end 133 and the inner wall of the inner cavity 113. When the hook 131 is squeezed, the movable end 133 will squeeze the elastic element 135. The elastic element 135 is a threaded spring, which will accumulate elastic potential energy when squeezed. When the hook 131 is no longer squeezed, the elastic element 135 will push the movable end 133 and the hook 131 back to their original positions, so that the hook 131 completes the reset work. At this time, the hook 131 can be driven away from the middle part of the valve plate, so that the clamping structure can be quickly separated from the valve plate.

[0056] It should be noted that the locking block 134 can prevent the hook 131 from disengaging from the inner cavity 113 when the hook 131 moves.

[0057] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
