Description

Technical Field

[0001] This utility model relates to the field of gate technology, specifically to a device for opening the gate hole grid cover. Background Technology

[0002] Flat-plate steel gates are a widely used and important facility in various water conservancy projects. These gates are typically made of high-quality steel and are characterized by their robust structure and excellent sealing performance. During installation, the gate is precisely hoisted into the pre-cast gate slot, and its lifting and lowering operations are achieved through a specially configured hoisting system. When the gate needs to be closed, the operator controls the hoist to slowly lower the gate until the bottom of the gate is completely seated at the bottom of the gate slot, at which point it is fully closed. To ensure the safety and daily maintenance of the gate slot, multiple specially designed steel grating covers are commonly used for sealing and covering. These covers not only have sufficient load-bearing capacity but also effectively prevent debris from entering the gate slot.

[0003] However, when it is necessary to lift the gate, removing these covers not only requires multiple people to work together, but also poses safety hazards due to working near water and the edge. For large-span, multi-hole gates, the operation time is even longer when they are opened at the same time. Therefore, we propose a more convenient and practical device for opening the gate hole grid cover to meet the usage requirements. Utility Model Content

[0004] The purpose of this utility model is to provide a device for opening the gate hole grid cover plate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for opening a gate hole grid cover plate, comprising an installation frame, a slot at the top of the installation frame, a grid cover plate body disposed within the slot, rotating blocks fixedly connected to both sides of the grid cover plate body, fixed blocks fixedly connected to both sides of the top of the installation frame, the fixed blocks and the rotating blocks being rotatably connected, an installation plate fixedly connected to one side of the installation frame, buffer mechanisms disposed on both sides of the top of the installation plate, the buffer mechanisms comprising fixed tubes, and a buffer plate disposed at the top of the fixed tubes.

[0006] Furthermore, a magnetic suction plate is fixedly connected to one side of the grille cover body, and a magnet is provided on one side of the magnetic suction plate, with the magnet connected to the mounting frame.

[0007] Furthermore, the fixing tube and the mounting plate are connected, and a damping rod is fixedly connected to the center of the bottom of the fixing tube.

[0008] Furthermore, a sliding plate is fixedly connected to one end of the damping rod, and the sliding plate and the fixed tube are slidably connected. A first spring is provided at the bottom of the sliding plate, and one end of the first spring is in contact with the inner wall of the bottom of the fixed tube.

[0009] Furthermore, a cross-shaped groove is provided on one side of the fixed tube, and a sliding block is slidably connected in the groove. The sliding block and the sliding plate are connected, and a fixed rod is fixedly connected to the top center of the sliding plate.

[0010] Furthermore, a support plate is fixedly connected to one end of the fixed rod, and the support plate and the buffer plate are connected to each other. A through hole is opened in the center of the top of the sliding block, and a sliding column is slidably connected in the through hole. One end of the sliding column is connected to the support plate, and a second spring is installed on the outer wall of the sliding column.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device for opening the gate hole grating cover plate, through the setting of the buffer mechanism, when the grating cover plate body is opened or closed during use, the impact force is transmitted to the support plate through the buffer plate, which drives the sliding column to slide in the sliding block and is buffered by the second spring. At the same time, the fixing rod makes the sliding plate slide in the fixing tube and is buffered by the first spring. Simultaneously, the damping rod limits the movement. This device does not require manual operation when opening, improves the gate opening efficiency, has strong safety, and is more convenient and faster when opening multiple gates. It is highly practical and suitable for promotion.

[0013] Meanwhile, without adding complex devices such as motors, hydraulics, and pneumatics, the grid cover is flipped by the lifting force of the gate, and the grid cover is opened quickly and smoothly by using steel wire ropes to buffer and dissipate the force. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During the use of the gate, a grating cover opening device is required. Regular maintenance and upkeep are necessary during this process. Check the wear of each component and replace any damaged parts promptly to ensure long-term stable operation. Pay attention to the operating environment and regularly check the first spring 804 and the second spring 809 for deformation, fatigue, or corrosion. If their elasticity is weakened or they break, replace them immediately to prevent buffer failure. Do not apply impact forces or heavy loads beyond the design range to the cover plate to prevent damage to components such as springs and damping rods 802 due to overload. If abnormal noises, jamming, or delayed reset are detected during cover opening and closing, stop the machine immediately for inspection and troubleshooting before resuming operation.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: a device for opening a gate hole grid cover plate, including a mounting frame 1, a slot is opened at the top of the mounting frame 1, a grid cover plate body 2 is arranged in the slot, rotating blocks 3 are fixedly connected to both sides of the grid cover plate body 2, fixing blocks 4 are fixedly connected to both sides of the top of the mounting frame 1, the fixing blocks 4 and the rotating blocks 3 are rotatably connected, a mounting plate 7 is fixedly connected to one side of the mounting frame 1, a buffer mechanism 8 is arranged on both sides of the top of the mounting plate 7, the buffer mechanism 8 includes a fixing tube 801, and a buffer plate 9 is arranged on the top of the fixing tube 801.

[0021] like Figure 2 As shown, a magnetic plate 5 is fixedly connected to one side of the grid cover body 2, and a magnet 6 is provided on one side of the magnetic plate 5. The magnet 6 is connected to the mounting frame 1.

[0022] It should be noted that during use, the mounting frame 1 is first installed in the gate slot, and the grid cover body 2 is fixed by the magnetic suction plate 5 and the magnet 6. When the hoisting machine raises and lowers the gate, the gate lifts and flips the grid cover body 2 by means of the gate lifting force through the fixed block 4 and the rotating block 3. After flipping, the impact force is absorbed by the buffer mechanism 8. No complex devices such as motors, hydraulics, or pneumatics are added. The grid cover is flipped by means of the gate lifting force, and the grid cover is opened quickly and smoothly by means of the steel wire rope buffer and force dissipation.

[0023] like Figure 3As shown, the fixed tube 801 and the mounting plate 7 are connected. A damping rod 802 is fixedly connected to the center of the bottom of the fixed tube 801. A sliding plate 803 is fixedly connected to one end of the damping rod 802. The sliding plate 803 and the fixed tube 801 are slidably connected. A first spring 804 is provided at the bottom of the sliding plate 803. One end of the first spring 804 is in contact with the inner wall of the bottom of the fixed tube 801. A cross-shaped groove is opened on one side of the fixed tube 801. A sliding block 805 is slidably connected in the groove. The sliding block 805 and the sliding plate 803 are connected. A fixed rod 806 is fixedly connected to the center of the top of the sliding plate 803. A support plate 807 is fixedly connected to one end of the fixed rod 806. The support plate 807 and the buffer plate 9 are connected. A through hole is opened at the center of the top of the sliding block 805. A sliding column 808 is slidably connected in the through hole. One end of the sliding column 808 is connected to the support plate 807. A second spring 809 is installed on the outer wall of the sliding column 808.

[0024] It should be noted that during use, when the grating cover body 2 is opened or closed, the impact force is transmitted to the support plate 807 through the buffer plate 9, which drives the sliding column 808 to slide in the sliding block 805 and is buffered by the second spring 809. At the same time, the fixing rod 806 causes the sliding plate 803 to slide in the fixing tube 801 and is buffered by the first spring 804. It is also limited by the damping rod 802. The buffering mechanism 8 can effectively reduce the impact force when the grating cover is opened and closed, and avoid structural damage or noise caused by rigid collision.

[0025] During use, the mounting frame 1 is first installed in the gate slot, and the grid cover body 2 is fixed by the magnetic suction plate 5 and the magnet 6. When the hoist opens and closes the gate, the gate lifts and flips the grid cover body 2 by means of the gate lifting force through the fixed block 4 and the rotating block 3. After flipping, the impact force generated by the falling of the grid cover body 2 is transmitted to the support plate 807 through the buffer plate 9, which drives the sliding column 808 to slide in the sliding block 805 and is buffered by the second spring 809. At the same time, the fixed rod 806 makes the sliding plate 803 slide in the fixed tube 801 and is buffered by the first spring 804. At the same time, the damping rod 802 limits the movement. This device does not require manual operation when opening, improves the gate opening efficiency, has strong safety, and is more convenient and faster when opening multiple gates. At the same time, it does not add complex devices such as motors, hydraulics, and pneumatics. The grid cover is flipped by means of the gate lifting force and the steel wire rope is used to buffer and dissipate the force, so that the grid cover can be opened quickly and smoothly.

[0026] 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 embodiments and their equivalents.
