Description

Technical Field

[0001] The utility model relates to the technical field of buffering and limiting, in particular to an adjustable buffering and limiting device. Background Art

[0002] Steel gates are typically movable structures used to open and close water inlets within local hydraulic structures. They are widely used in water supply and drainage, water conservancy, and hydropower projects as water-blocking and water-stopping devices. In hydraulic structures such as hydropower stations, reservoirs, sluices, and ship locks, steel gates precisely control water flow through opening and closing, thereby regulating water levels, preventing floods and draining water, and ensuring the rational use of water resources. They also play a vital role in irrigation and power generation. Due to their heavy weight and size, steel gates are prone to colliding with their frames during closing. This collision can cause dents, scratches, or even more severe deformation in the gate panels, compromising their sealing and service life. Similarly, the frame can also be damaged by collisions, such as deformation and cracking, compromising the stability and safety of the entire structure. Therefore, an adjustable buffering and limiting device is needed to prevent collisions between the gate panels and the frame during closing, thereby reducing the risk of damage to the gate panels and frame and extending the service life of the steel gate.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A kind of adjustable buffer limit device comprises a buffer limit assembly, and the buffer limit assembly is installed in the connecting frame on the lower side. The buffer limit assembly consists of a base plate, a connecting plate, a buffer spring, a support plate, a limit plate and a rubber pad. The connecting plate is fixedly installed on the front end of the base plate. There are several buffer springs and they are all fixedly installed on the upper end of the base plate. The support plate is fixedly installed on the upper ends of several buffer springs. There are two limit plates and they are symmetrically fixed on the rear end of the support plate.

[0006] Preferably, there are two connecting frames and they are symmetrically arranged in the upper and lower directions. Two side frames are symmetrically fixedly installed on the left and right ends of the two connecting frames. A rotating handle is rotatably installed on the upper connecting frame, and a lifting screw is installed on the rotating handle.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By arranging a buffer limiting component in the lower connecting frame, the buffer limiting component can block and buffer the closed gate door panel, thereby slowing down the movement speed of the gate door panel, further reducing the impact force of the gate door panel, and finally avoiding the collision between the gate door panel and the lower connecting frame when the gate door panel is closed, thereby reducing the probability of damage to the gate door panel and the lower connecting frame, and further improving the service life of the steel gate; By arranging an adjusting threaded rod on the connecting frame and the buffer limiting component, the base plate on the buffer limiting component can be adjusted, thereby adjusting the distance between the base plate and the support plate, and further adjusting the supporting force of the buffer limiting component by compressing the buffer spring. Finally, the buffer limiting component can better adapt to different load requirements. When the impact force when the gate door panel is closed is large, the supporting force of the buffer limiting component can be appropriately increased to provide stronger support. On the contrary, when the impact force when the gate door panel is closed is small, the supporting force of the buffer limiting component can be reduced to reduce wear.

Detailed implementation manners

[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific implementation manners.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown in the figure, a regulating buffer limiting device includes a buffer limiting component 3. The buffer limiting component 3 is installed in the lower connecting frame 2. The buffer limiting component 3 is composed of a base plate 11, a connecting plate 12, a buffer spring 14, a support plate 15, a limiting plate 16 and a rubber pad 17. The connecting plate 12 is fixedly installed at the front end of the base plate 11. There are several buffer springs 14, and they are all fixedly installed at the upper end of the base plate 11. The support plate 15 is fixedly installed at the upper ends of several buffer springs 14. There are two limiting plates 16, and they are symmetrically and fixedly installed at the rear end of the support plate 15. The rubber pad 17 is fixedly installed at the upper end of the support plate 15. An adjusting threaded rod 4 is installed on the lower connecting frame 2 and the buffer limiting component 3. There are two connecting frames 2, and they are symmetrically arranged up and down. Two side frames 1 are symmetrically and fixedly installed at the left and right ends of the two connecting frames 2. A rotating handle 5 is rotatably installed on the upper connecting frame 2. An elevating screw rod 6 is installed on the rotating handle 5. The lower end of the elevating screw rod 6 is fixedly installed with a gate door panel 7, and the gate door panel 7 is movably installed in the two side frames 1. The front end of the lower connecting frame 2 is fixedly installed with a mounting plate 8. A hole is opened on the mounting plate 8. A communication groove 10 is opened on the front side wall of the lower connecting frame 2 and below the mounting plate 8. Two limiting grooves 9 are symmetrically opened on the rear side wall of the lower connecting frame 2. When in use, the side frames 1 and the connecting frames 2 can be fixed in the river channel. The elevating screw rod 6 and the rotating handle 5 are connected by threads. When it is necessary to open or close the gate door panel 7, the rotating handle 5 can be horizontally rotated on the upper connecting frame 2. At this time, as the rotating handle 5 rotates, the elevating screw rod 6 will drive the gate door panel 7 to rise or fall, so that the opening or closing of the gate door panel 7 can be completed. When the gate door panel 7 moves downward and closes, the gate door panel 7 will impact the rubber pad 17 and the support plate 15 on the buffer limiting component 3. At this time, the rubber pad 17, the limiting plate 16 and the support plate 15 will move downward to compress the buffer spring 14. Thus, during the process of the buffer spring 14 being compressed, the buffering and limiting of the gate door panel 7 can be realized. When the gate door panel 7 is inserted into the lower connecting frame 2, the closing of the gate door panel 7 is completed;When it is necessary to adjust the supporting force of the buffer limiting component 3, the adjusting screw rod 4 can be rotated, so that the base plate 11 and the connecting plate 12 move upward or downward. When the base plate 11 and the connecting plate 12 move upward, the buffer spring 14 will be compressed, and at this time, the supporting force of the buffer limiting component 3 will become stronger. When the base plate 11 and the connecting plate 12 move downward, the supporting force of the buffer limiting component 3 will weaken. By arranging the buffer limiting component 3 in the lower connecting frame 2, the buffer limiting component 3 can block and buffer the closed gate panel 7, thereby slowing down the movement speed of the gate panel 7, further reducing the impact force of the gate panel 7, and finally avoiding the collision between the gate panel 7 and the lower connecting frame 2 when the gate panel 7 is closed, so as to reduce the probability of damage to the gate panel 7 and the lower connecting frame 2, and further improve the service life of the steel gate. By arranging the adjusting screw rod 4 on the connecting frame 2 and the buffer limiting component 3, the base plate 11 on the buffer limiting component 3 can be adjusted, so as to adjust the distance between the base plate 11 and the support plate 15, and further adjust the supporting force of the buffer limiting component 3 by compressing the buffer spring 14. Finally, the buffer limiting component 3 can better adapt to different load requirements. When the impact force when the gate panel 7 is closed is large, the supporting force of the buffer limiting component 3 can be appropriately increased to provide stronger support. On the contrary, when the impact force when the gate panel 7 is closed is small, the supporting force of the buffer limiting component 3 can be reduced to reduce wear.

[0020] Further, the base plate 11, the support plate 15 and the rubber pad 17 on the buffer limiting component 3 are all movably installed in the lower connecting frame 2, the limiting plate 16 is movably installed in the limiting groove 9, the connecting plate 12 on the buffer limiting component 3 passes forward through the communication groove 10, and a threaded hole 13 is opened on the connecting plate 12. The adjusting screw rod 4 is rotatably installed in the hole opened on the mounting plate 8, and the adjusting screw rod 4 is simultaneously installed in the threaded hole 13 opened on the connecting plate 12. During the closing process of the gate panel 7, when the rubber pad 17 and the support plate 15 are squeezed, the limiting plate 16 will move downward in the limiting groove 9. When the rubber pad 17 and the support plate 15 lose the extrusion of the gate panel 7, under the elastic action of the buffer spring 14, the rubber pad 17, the limiting plate 16 and the support plate 15 will move upward to reset. When adjusting the distance between the base plate 11 and the support plate 15, the adjusting screw rod 4 can be horizontally rotated on the mounting plate 8. At this time, as the adjusting screw rod 4 rotates, the connecting plate 12 will drive the base plate 11 to move upward or downward. When the connecting plate 12 and the base plate 11 move upward, the buffer spring 14 will be compressed. On the contrary, the buffer spring 14 will stretch out.
