Description

Technical Field

[0001] This utility model belongs to the field of water conservancy gate maintenance technology, and in particular relates to a lateral synchronous sliding device for a water gate maintenance gate. Background Technology

[0002] Working gates serve the long-term function of normal water blocking and discharge, but cannot simultaneously block water during maintenance of themselves or surrounding structures. Maintenance gates, as dedicated temporary water blocking devices, can cut off water flow to provide a waterless working environment, avoid water flow interference during maintenance, prevent safety accidents such as personnel falling into the water or equipment being washed away, and reduce construction risks. They are an indispensable supporting facility for sluice gate systems. Under current circumstances, maintenance gates placed on sluice gate piers can only be transported by crane, which is costly and involves complicated on-site lifting procedures. Furthermore, the crane working surface is prone to causing significant damage to the sluice gate wing wall greening and the maintenance bridge and traffic bridge railings, resulting in high restoration costs later. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a lateral synchronous sliding device for maintenance gates of sluice gates, which is used to solve the problems in the transportation and use of maintenance gates of small and medium-sized sluice gates, improve the efficiency of maintenance gate use, and give full play to the benefits of the project.

[0004] The technical solution adopted by this utility model is as follows: a lateral synchronous sliding device for a maintenance gate of a sluice gate project, including a maintenance gate slot pier for support, the upper end of the maintenance gate slot pier being connected to the gate working bridge, the side of the maintenance gate slot pier being connected to the working bridge surface, the space between the maintenance gate slot piers forming a gate passage, and a set of gate leaf moving devices being provided on the top of the maintenance gate slot piers on both the left and right sides of each gate passage, with two sets in total for each gate passage, and a first maintenance gate and a second maintenance gate installed on the top of the maintenance gate slot piers on both the left and right sides of each gate passage, the first maintenance gate being located close to the working bridge surface.

[0005] The maintenance gate slot piers are all provided with sliding grooves at the top, and the side walls of the maintenance gate slot piers on both sides of each gate passage are provided with gate slots. The sliding grooves are connected to the gate slots. A slide rail is detachably installed in the sliding groove.

[0006] The gate slot contains an I-beam that is movably installed. The first maintenance gate is placed in the gate slot and its bottom wall is located on the I-beam. The I-beam supports the first maintenance gate. When it is necessary to place the first maintenance gate on the bottom wall of the gate slot to block the water flow, the I-beam can be pulled out of the gate slot.

[0007] The gate leaf moving device includes an electric push rod, an electrical control device, and a gate leaf lifting lug cover. The electric push rod is located on the top of the gate slot pier of the maintenance gate. The gate leaf lifting lug cover is detachably installed in the sliding groove.

The connection between the electric push rod and the gate leaf lifting lug cover is achieved by bolts. The electrical control device is placed on the top of the gate slot pier of the maintenance gate and is electrically connected to the electric push rod.

[0008] Furthermore, the bottom wall of the door leaf hanging ear cover is provided with a slot, which is matched with the slide rail. When the slide rail is placed in the slide groove, the door leaf hanging ear cover is movably engaged with the slide rail through the slot.

[0009] The two ends of the second maintenance gate are movably installed inside the gate leaf lifting lugs; the electric push rods on the gate slot piers of the maintenance gates on the left and right sides of each gate move synchronously, and can drive the gate leaf lifting lugs through the connecting parts. The gate leaf lifting lugs drive the second maintenance gate on them to move to the position of the gate slot.

[0010] The first and second maintenance gates have the same structure, and only one set will be described here. The upper wall of the first maintenance gate has two sets of connecting frames symmetrically installed, and each set of connecting frames has a connecting groove. The bottom wall of the first maintenance gate has two sets of fixing grooves symmetrically installed. The positions of the fixing grooves match the positions of the connecting grooves. When the first maintenance gate is placed on the bottom wall of the gate groove to block the water flow, and the second maintenance gate is also placed in the gate groove, the connecting frame on the first maintenance gate is inserted into the fixing groove on the bottom wall of the second maintenance gate.

[0019] like Figures 1-5 As shown, a lateral synchronous sliding device for a maintenance gate in a sluice gate project includes a maintenance gate slot pier 1 for support. The upper end of the maintenance gate slot pier 1 is connected to the gate working bridge 2, and the side of the maintenance gate slot pier 1 is connected to the working bridge surface 3. The area between the maintenance gate slot piers 1 is a gate passage. A set of gate leaf moving devices 4 is provided on the top of the maintenance gate slot piers 1 on both the left and right sides of each gate passage. There are two sets of these devices in each gate passage. A first maintenance gate 5 and a second maintenance gate 6 are installed on the top of the maintenance gate slot piers 1 on both the left and right sides of each gate passage. The first maintenance gate 5 is located close to the working bridge surface 3.

[0020] The top of each maintenance gate slot pier 1 is provided with a sliding groove 7, and the side walls of the maintenance gate slot pier 1 on both sides of each gate passage are provided with a gate slot 8. The sliding groove 7 and the gate slot 8 are connected through each other. A slide rail is detachably installed in the sliding groove 7. One end of the slide rail is located in the sliding groove 7, and the other end is movably attached to the side wall of the working bridge 3. The slide rail is existing technology and can be placed on the upper end of the gate slot 8 to provide a sliding track for the gate leaf lifting lug 11.

[0021] An I-beam 9 is movably installed in the gate slot 8. The first maintenance gate 5 is placed in the gate slot 8 and its bottom wall is located on the I-beam 9. The I-beam 9 supports the first maintenance gate 5. When it is necessary to place the first maintenance gate 5 on the bottom wall of the gate slot 8 to block the water flow, the I-beam 9 can be pulled out from the gate slot 8.

[0022] The gate leaf moving device 4 includes an electric push rod 10, an electrical control device, and a gate leaf lifting lug 11. The electric push rod 10 is located on the top of the gate slot pier 1 of the maintenance gate. The gate leaf lifting lug 11 is detachably installed in the sliding groove 7. A connector 12 is installed on the side wall of the gate leaf lifting lug 11. The movable end of the electric push rod 10 can extend into the connector 12. The connection between the electric push rod 10 and the gate leaf lifting lug 11 is achieved by bolts. The electrical control device is placed on the top of the gate slot pier 1 of the maintenance gate. The electrical control device is electrically connected to the electric push rod 10. Each electric push rod 10 has a dynamic load of 12kN, a speed of 0.018m / s, and a power of 0.55kW. Two electric push rods 10 are opened and closed simultaneously in each hole. The electrical control device controls the operation of the electric push rod 10 manually.

[0023] The bottom wall of the door leaf hanging ear cover 11 is provided with a slot 13, which is matched with the slide rail. When the slide rail is placed in the slide groove 7, the door leaf hanging ear cover 11 is movably engaged with the slide rail through the slot 13.

[0024] The two ends of the second maintenance gate 6 are movably installed inside the gate leaf lifting lug 11; the electric push rods 10 on the gate slot piers 1 on the left and right sides of each gate move synchronously, and can drive the gate leaf lifting lug 11 through the connecting piece 12. The gate leaf lifting lug 11 drives the second maintenance gate 6 on it to move, and moves the second maintenance gate 6 to the position of the gate slot 8.

[0025] The first maintenance gate 5 and the second maintenance gate 6 have the same structure. Only one set is described here. The upper wall of the first maintenance gate 5 is symmetrically equipped with two sets of connecting frames 14. Each set of connecting frames 14 is provided with a connecting groove 15. The bottom wall of the first maintenance gate 5 is symmetrically equipped with two sets of fixing grooves 16. The positions of the fixing grooves 16 and the connecting grooves 15 are matched. When the first maintenance gate 5 is placed on the bottom wall of the gate groove 8 to block the water flow, and the second maintenance gate 6 is also placed in the gate groove 8, the connecting frame 14 on the first maintenance gate 5 is inserted into the fixing groove 16 on the bottom wall of the second maintenance gate 6.

[0026] The bottom wall of the gate working bridge 2 is equipped with an I-beam 17, and a bridge crane 18 is movably mounted on the I-beam 17. The bridge crane 18 is located at the upper end of the gate slot 8. A lifting beam 19 is installed at the movable end of the bridge crane 18. Two sets of lifting rods 20 are symmetrically installed on the bottom wall of the lifting beam 19. The position of the lifting rods 20 matches the position of the connecting slot 15. The bridge crane 18 can move horizontally along the I-beam 17, and the bridge crane 18 can also drive the lifting beam 19 to move up and down.

[0027] The lifting beam 19 is provided with a placement cavity 21, and a limiting cylinder 22 is installed in the placement cavity 21. The upper end of the limiting cylinder 22 is connected to the upper wall of the placement cavity 21, and the lower end of the limiting cylinder 22 is connected to the bottom wall of the placement cavity 21. A limiting groove 23 is provided on the outer wall of the limiting cylinder 22. The upper end of the lifting rod 20 is movably inserted through the bottom wall of the lifting beam 19 and then placed in the limiting cylinder 22. Two sets of insert rods 24 are symmetrically installed on the part of the lifting rod 20 placed in the limiting cylinder 22. The insert rods 24 are movably engaged in the limiting groove 23.

[0028] It should be noted that the lifting beam 19 drives the lifting rod 20 to move up and down. When the lifting beam 19 moves down, the lifting rod 20 is inserted into the connecting groove 15 until it moves to the upper wall of the maintenance gate. As the lifting beam 19 continues to move down, under the action of gravity, the lifting beam 19 squeezes the lifting rod 20. The lifting rod 20 drives the insertion rod 24 to rotate along the upper inclined surface of the limiting groove 23. Then the lifting beam 19 rises and drives the lifting rod 20 to rise. The lifting rod 20 rotates again under the action of the lower inclined surface of the limiting groove 23. It rotates 90 degrees twice. Then the lifting beam 19 rises and drives the lifting rod 20 to continue to rise. The rotated lifting rod 20 can drive the maintenance gate to rise. After the maintenance gate is placed, follow the above steps to rotate the lifting rod 20 by 90 degrees again. As the lifting beam 19 moves upward, the lifting rod 20 disengages from the connecting groove 15. The above working process is existing technology and is used in many water conservancy projects.

[0029] In practical use: When the working gate is under maintenance, the lifting rod 20 at the lower end of the bridge crane 18 is inserted into the connecting groove 15 on the first maintenance gate 5. Then, the rotating lifting rod 20 moves upward with the lifting beam 19. After the first maintenance gate 5 is raised, the I-beam 9 in the gate slot 8 is removed, and then the first maintenance gate 5 is placed into the gate slot 8. After the lifting rod 20 is disengaged from the connecting groove 15, it is raised with the lifting beam 19. After the lifting rod 20 is higher than the top of the gate slot 8, the slide rail is placed on the slide groove 7 and the gate slot 8. The electric push rod 10 is activated to open the maintenance gate. The second maintenance gate 6, placed on top of the pier 1, is pushed into the gate slot 8. The lifting rod 20 at the lower end of the bridge crane 18 is inserted into the connecting groove 15 on the second maintenance gate 6. Then, the rotating lifting rod 20 moves upward with the lifting beam 19 to support the second maintenance gate 6. After the bolts between the electric push rod 10 and the connecting piece 12 are removed, the electric push rod 10 retracts. After the second maintenance gate 6 is raised, the door leaf lifting lug 11 is removed from both ends of the second maintenance gate 6. At the same time, the slide rail is pulled out from the gate slot 8, and then the second maintenance gate 6 is put back into the gate slot 8.

[0030] When the working gate is repaired, the second maintenance gate 6 is first lifted to the top of the gate slot pier 1, then the slide rail is placed into the gate slot 8, the gate leaf lifting lugs 11 are fitted onto both ends of the second maintenance gate 6, the second maintenance gate 6 is lowered onto the slide rail, the electric push rod 10 is started, and the electric push rod 10 is connected to the connecting piece 12 on the gate leaf lifting lug 11 with bolts. Then the electric push rod 10 moves the second maintenance gate 6 to the initial position for placement.

[0031] Two sets of electric push rods 10 for each hole should operate synchronously, using local control locking and opening modes, with automatic power-off function when locked and opened, and a signal indication of the position.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
