A fixing clamping device for a flood gate

Abstract

This invention discloses a fixing and clamping device for a floodgate, comprising a gate and movable steel supports located at both ends of the gate. A support is connected to the outer wall of the gate adjacent to the movable steel support. A lead screw is laterally rotatably mounted within the support. A fixing beam is fixed to the outer wall of the movable steel support corresponding to the support. The end of the fixing beam protrudes from the movable steel support, and a positioning hole is formed on the end side wall corresponding to the lead screw. A nut is threaded onto the tail end of the lead screw. A baffle with a diameter larger than the width of the positioning hole is provided at the front end of the nut. A cotton pad that can absorb lubricating oil is provided on the front face of the baffle. A drainage groove is formed along the axial direction on the outer wall of the lead screw. The cotton pad is squeezed, causing lubricating oil to flow out and coat the outer surface of the lead screw. The drainage groove allows the lubricating oil to remain on the surface of the lead screw for a longer time, while also facilitating the diffusion of the lubricating oil. This, to a certain extent, prevents rust from forming on the threads of the nut and the lead screw, maintaining the long-term reliability of the nut and the lead screw.

Description

Technical Field

[0001] This invention relates to the field of floodgate technology, and in particular to a fixing and clamping device for floodgates. Background Technology

[0002] In modern urban construction, a large amount of underground space is utilized, resulting in many underground spaces being lower than urban drainage pipes. The main sources of urban flooding are river floods and rainstorms, so floodgates are used to resist floods.

[0003] Currently, floodgates are generally connected to their supports using screws and nuts. However, the screws and nuts of floodgates are exposed and in contact with water, and the threads of the screws and nuts are prone to rust, making it difficult to disassemble and assemble the screws and nuts, which affects the opening and closing of the gate and the support. Therefore, we propose a fixing and clamping device for floodgates. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a fixing clamping device for a floodgate. The cotton pad is squeezed so that the lubricating oil flows out and is applied to the outer surface of the lead screw. The drainage groove allows the lubricating oil to stay on the surface of the lead screw for a longer time, and at the same time facilitates the diffusion of the lubricating oil. This can prevent rust from forming on the threads of the nut and the lead screw to a certain extent, and maintain the long-term reliability of the nut and the lead screw.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fixing clamping device for a floodgate, comprising a gate and movable steel supports disposed at both ends of the gate. The gate is connected to a support on the outer side wall adjacent to the movable steel support. A threaded rod is rotatably disposed in the support. A fixing beam is fixedly connected to the support on the outer side wall of the movable steel support. The end of the fixing beam protrudes from the movable steel support, and a positioning hole is opened on the end side wall corresponding to the threaded rod. A nut is threadedly fitted onto the tail end of the threaded rod. A baffle with a diameter larger than the width of the positioning hole is provided at the front end of the nut. A cotton pad that can absorb lubricating oil is provided on the front end face of the baffle. A drainage groove is opened along the axial direction on the outer side wall of the threaded rod.

[0006] Preferably, the front end face of the baffle is provided with an oil storage groove, and the cotton pad covers the outside of the port of the oil storage groove.

[0007] Preferably, the baffle is fixedly connected to the nut, and an oil outlet hole is provided between the oil storage tank and the inner wall of the nut.

[0008] Preferably, the tail end of the nut is coaxially connected and fixed with a throttle handle.

[0009] Preferably, the cotton pad is attached to the edge of the end face of the baffle and is connected with a connecting buckle. The end face of the baffle is provided with a slot corresponding to the connecting buckle, and the connecting buckle and the slot are movably engaged.

[0010] Preferably, the gate is covered with reinforcing strips, and the side of the gate is connected with crisscrossing support strips, the ends of which are fixed to the reinforcing strips.

[0011] Preferably, a reinforcing strip is obliquely arranged on the side of the gate between the support strips, and the reinforcing strip and the adjacent support strip form a triangular structure.

[0012] Preferably, the gate is provided with symmetrical hanging buckles on both sides of its top.

[0013] Preferably, the bottom ends of the movable steel support extend outward and are connected by bolts.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] The gate's screw rod rotates laterally relative to the support and engages in the positioning hole of the fixed beam on the movable steel support. When the baffle contacts the fixed beam, the cotton pad is squeezed, causing lubricating oil to flow out and coat the outer surface of the screw rod. The drainage groove can store lubricating oil to a certain extent, allowing the lubricating oil to stay on the screw rod surface for a longer time. At the same time, the drainage groove facilitates the diffusion of lubricating oil on the screw rod surface. The nut rotates relative to the screw rod, and its threads are coated with lubricating oil, making the movement of the nut and screw rod smoother and less prone to jamming. At the same time, the lubricating oil protects the nut and screw rod, reduces wear, extends service life, and to a certain extent prevents rust from forming on the threads of the nut and screw rod, maintaining the long-term reliability of the nut and screw rod.

Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0025] Example

[0026] Please refer to Figure 1 , Figure 4 and Figure 5As shown, the present invention provides a fixing clamping device for a floodgate, including a gate 1 and movable steel supports 2 disposed at both ends of the gate 1. A support 8 is connected to the outer wall of the gate 1 adjacent to the movable steel supports 2. A threaded rod 11 is laterally rotatably disposed within the support 8. A fixing beam 9 is fixedly connected to the outer wall of the movable steel supports 2 corresponding to the support 8. The end of the fixing beam 9 protrudes from the movable steel supports 2, and a positioning hole 10 is opened on the end side wall corresponding to the threaded rod 11. The tail end of the threaded rod 11 is threaded... The assembly includes a nut 12, with a baffle 13 at its front end that has a diameter larger than the width of the positioning hole 10. A cotton pad 16 for absorbing lubricating oil is placed on the front face of the baffle 13. A drainage groove 15 is axially formed on the outer wall of the lead screw 11. The gate 1 is hoisted between the movable steel supports 2 and accurately aligned. The lead screw 11 of the gate 1 rotates laterally relative to the support 8 and engages in the positioning hole 10 of the fixed beam 9 on the movable steel support 2. The nut 12 rotates relative to the lead screw 11 and screws in. This pushes the baffle 13, which blocks the fixed beam 9. Due to the interaction of forces, the screw rod 11 pulls the gate 1 and the movable steel support 2 together and clamps them. The cotton gasket 16 contains pre-absorbed lubricating oil. When the baffle 13 contacts the fixed beam 9, the cotton gasket 16 is squeezed, causing the lubricating oil to flow out and coat the outer surface of the screw rod 11. The drainage groove 15 can store the lubricating oil to a certain extent, allowing the lubricating oil to stay on the surface of the screw rod 11 for a longer time. At the same time, the drainage groove 15 facilitates the diffusion of the lubricating oil on the surface of the screw rod 11. The nut 12 rotates relative to the screw rod 11, and its threads are coated with lubricating oil. The movement of the nut 12 and the screw rod 11 is smoother and less prone to jamming. That is, the clamping and fixing operation of the gate 1 and the movable steel support 2 is easier. At the same time, the lubricating oil protects the nut 12 and the screw rod 11, reduces wear, extends service life, and to a certain extent prevents rust from forming on the threads of the nut 12 and the screw rod 11, maintaining the long-term reliability of the nut 12 and the screw rod 11.

[0027] like Figure 5 , Figure 6 and Figure 7 As shown, the present invention discloses that the front end face of the baffle 13 is provided with an oil storage groove 17, the cotton pad 16 covers the outside of the port of the oil storage groove 17, the baffle 13 is connected and fixed with the nut 12, the oil storage groove 17 and the inner wall of the nut 12 are connected and provided with an oil outlet hole 18, and the tail end of the nut 12 is coaxially connected and fixed with a throttle 14.

[0028] like Figure 6 and Figure 7 As shown, the present invention discloses that the end face edge of the cotton pad 16 is attached to the baffle 13 and is connected with a connecting buckle 20. The end face of the baffle 13 is provided with a slot 19 corresponding to the connecting buckle 20, and the connecting buckle 20 and the slot 19 are movably engaged.

[0029] like Figure 3As shown, the present invention discloses that the edge of the gate 1 is covered with a reinforcing strip 4, the side of the gate 1 is connected with crisscrossing support strips 6, the end of the support strip 6 is fixed to the reinforcing strip 4, and the side of the gate 1 is provided with a reinforcing strip 7 diagonally between the support strips 6, and the reinforcing strip 7 and the adjacent support strip 6 form a triangular structure.

[0030] like Figure 2 and Figure 3 As shown, the present invention discloses that the top two sides of the gate 1 are symmetrically provided with hooks 5, and the bottom two ends of the movable steel support 2 extend outward and are connected with bolts 3.

[0031] This invention provides a fixing and clamping device for a floodgate. The gate 1 is hoisted between movable steel supports 2 and accurately aligned. The screw rod 11 of the gate 1 rotates laterally relative to the support 8 and engages in the positioning hole 10 of the fixed beam 9 on the movable steel support 2. The nut 12 rotates relative to the screw rod 11, thus pushing the baffle 13. The baffle 13 blocks the fixed beam 9, and due to the interaction of forces, the screw rod 11 pulls the gate 1 and clamps it between the movable steel support 2. The cotton pad 16 contains pre-absorbed lubricating oil. When the baffle 13 contacts the fixed beam 9, the cotton pad 16 is squeezed, causing the lubricating oil to flow out and coat the screw rod 11. On the outer surface of 1, the drainage groove 15 can store lubricating oil to a certain extent, allowing the lubricating oil to stay on the surface of the lead screw 11 for a longer time. At the same time, the drainage groove 15 facilitates the diffusion of lubricating oil on the surface of the lead screw 11. When the nut 12 rotates relative to the lead screw 11, its threads are coated with lubricating oil, making the movement of the nut 12 and the lead screw 11 smoother and less prone to jamming. This makes the clamping and fixing operation of the gate 1 and the movable steel support 2 easier. At the same time, the lubricating oil protects the nut 12 and the lead screw 11, reducing wear and extending service life. It also prevents rust from forming on the threads of the nut 12 and the lead screw 11 to a certain extent, maintaining the long-term reliability of the nut 12 and the lead screw 11.
