Technical Field

[0001] This utility model relates to the field of screw gate hoisting technology, and in particular to a flat-push screw gate hoisting machine. Background Technology

[0002] The flat-push screw gate hoist is a special machine for water conservancy projects. It is mainly used in small reservoirs, canals, pumping stations, sewage treatment, water conservancy and hydropower, municipal construction, aquaculture and farmland water conservancy construction projects. It realizes the opening and closing of the gate through the screw drive.

[0003] Manually operated flat-push screw gate hoists are mostly used outdoors. Because the screw lifting and lowering needs to be controlled by operating the gate hoist, it is impossible to install a sealed protection for the screw lifting port. In rainy or snowy weather, rainwater can enter the gate hoist, which can easily cause internal parts to rust, accelerate wear, and reduce the service life of the gate hoist. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the screw lifting port cannot be sealed and protected when the screw is raised and lowered by operating the gate hoist, and rainwater can easily enter the gate hoist in rainy or snowy weather, causing internal parts to rust, aggravating wear, and reducing the service life of the gate hoist. The proposed invention is a flat-push screw gate hoist.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flat-push screw gate opener, including a base, a housing rotatably mounted on the top of the base, pre-drilled holes for easy installation at the four corners of the base, a threaded groove inside the housing, handles threadedly connected to both sides of the inner wall of the housing, and a sealing device at the top of the housing for sealing the connection between the top of the inner wall of the threaded groove and the outer side of the screw.

[0006] Preferably, the sealing device includes two mounting blocks and two sealing blocks. The mounting blocks are fixed to the top of the housing, and the ends of the two mounting blocks that are close to each other are not in contact. The top of the mounting block has two sliding grooves. The bottom of the sealing block is provided with two protrusions that slide inside the sliding grooves at the top of the mounting block. Two springs are provided on one side of the sealing block. The top of the mounting block is fixedly connected to two stops. The two ends of the springs are fixedly connected to one side of the sealing block and one side of the stops, respectively.

[0007] Preferably, the top of the sealing block is rotatably connected to an operating rod, and the top of the operating rod has a through groove.

[0008] Preferably, a positioning rod is fixedly connected to one end of the operating rod, and the positioning rod protrudes from the bottom surface of the operating rod.

[0009] Preferably, the mounting block is provided with a lubrication component that allows for easy addition of lubricating oil to the inside of the housing.

[0010] Preferably, the lubrication component includes a sponge block, and the mounting block has a rectangular groove inside. Two support rods are fixedly connected to the bottom of the inner wall of the rectangular groove. The sponge block is located above the two support rods inside the rectangular groove. An oil filling pipe and an oil delivery pipe are fixedly connected to the top and bottom of the mounting block, respectively. The end of the oil delivery pipe away from the mounting block is located inside the housing and penetrates the inner wall of the housing.

[0021] Example 1, as Figure 1-2 As shown, the flat-push screw gate opener includes a base 1, with a housing 3 rotatably mounted on the top of the base 1. Pre-drilled holes are provided at the four corners of the base 1 to facilitate installation. A threaded groove 4 is provided inside the housing 3. Handles 5 are threadedly connected to both sides of the inner wall of the housing 3. A sealing device 2 is provided at the top of the housing 3 to seal the connection between the top of the threaded groove 4 and the outer side of the screw connection. When installing the screw gate opener, the base 1 is placed at the top of the valve, and bolts or other fasteners are used to fix the base 1 in position by passing through the pre-drilled holes at the four corners. Then, the screw connected to the valve is passed through the threaded groove 4 inside the housing 3 (the installation of the screw gate opener is well-known to those skilled in the art and will not be described in detail here). When using the screw gate opener, one end of each of the two handles 5 can be inserted into the inner wall of the housing 3 and rotated to connect the handles 5 to the housing 3. Pushing the handles 5 controls the rotation of the housing 3, causing the screw to lift and lower the valve.

[0022] Reference Figure 1-5As shown in this embodiment: the sealing device 2 includes two mounting blocks 21 and two sealing blocks 23. The mounting blocks 21 are fixed to the top of the housing 3. The ends of the two mounting blocks 21 that are close to each other are not in contact. The top of the mounting blocks 21 has two sliding grooves 22. The bottom of the sealing blocks 23 is provided with two protrusions that slide inside the sliding grooves 22 at the top of the mounting blocks 21. Two springs 24 are provided on one side of the sealing blocks 23. The top of the mounting blocks 21 is fixedly connected to two stops 25. The two ends of the springs 24 are fixedly connected to one side of the sealing blocks 23 and one side of the stops 25, respectively. By setting the sealing blocks 23, after the screw hoist is installed, the ends of the sealing blocks 23 at the top of the two mounting blocks 21 that are close to each other will be tightly in contact with the outer surface of the screw, sealing the area above the contact point between the screw and the top of the threaded groove 4 inside the housing 3. When using the screw hoist, the two sealing blocks 23 are pulled by the top of the two mounting blocks 21 through the protrusions at the bottom of the mounting blocks 21. The inner wall of the top groove 22 slides away from each other and compresses the spring 24, causing the two sealing blocks 23 to move away from the outer surface of the screw. Then the screw can be controlled normally without being affected by the sealing blocks 23. After the screw hoist is used, the sealing blocks 23 are released and the spring 24 returns to its original state, which will push the two sealing blocks 23 closer together and stick to the outer surface of the screw again to seal the outside of the screw. By setting the sealing device 2, by installing two mounting blocks 21 and two sealing blocks 23 at the top of the housing 3, when the screw hoist is not in use, the ends of the two sealing blocks 23 that are close to each other stick to each other and are stuck on the outside of the screw, further sealing the connection between the screw and the threaded groove 4 at the top of the housing 3, and avoiding rainwater from entering the inside of the housing 3 through the outside of the connection between the screw and the housing 3, causing the internal parts to rust. The sealing block 23 can be moved when the hoist is used to avoid affecting the normal rotation of the screw.

[0023] Reference Figure 2-5 As shown in this embodiment: the top of the sealing block 23 is rotatably connected to an operating rod 26. The top of the operating rod 26 has a through groove. Holding the through groove on the outer surface of the operating rod 26 makes it easier to pull the sealing block 23 to control its movement. One end of the operating rod 26 is fixedly connected to a positioning rod 27. The positioning rod 27 protrudes from the bottom surface of the operating rod 26. When using the screw gate opener, after pulling the operating rod 26 to control the two sealing blocks 23 to move away from each other, one side of the positioning rod 27 can be attached to the outside of the stop block 25 to temporarily fix the operating rod 26 at the top of the stop block 25 and the sealing block 23 at the top of the mounting block 21, thereby improving the convenience of using the screw gate opener.

[0024] Reference Figure 2-4As shown, in this embodiment: the mounting block 21 is internally provided with a lubrication component 28 for conveniently adding lubricating oil to the inside of the housing 3. The lubrication component 28 includes a sponge block 284. A rectangular groove 282 is formed inside the mounting block 21. Two support rods 283 are fixedly connected to the bottom of the inner wall of the rectangular groove 282. The sponge block 284 is located above the two support rods 283 inside the rectangular groove 282. An oil filling pipe 281 and an oil delivery pipe 285 are fixedly connected to the top and bottom of the mounting block 21, respectively. The end of the oil delivery pipe 285 away from the mounting block 21 is located inside the housing 3 and penetrates the inner wall of the housing 3. The oil filling pipe 281... A plug 286 is inserted into the inner wall of 81. After the screw gate hoist is installed, lubricating oil can be added into the rectangular groove 282 through the oil supply pipe 285 at the top of the mounting block 21. After adding, the plug 286 is inserted into the oil supply pipe 281. After the lubricating oil enters the rectangular groove 282, it will enter the sponge block 284. The sponge block 284 will absorb the lubricating oil. The lubricating oil absorbed in the sponge block 284 will seep out over time and enter the housing 3 through the oil supply pipe 285 to lubricate the inner wall of the housing 3 and the outer surface of the screw, further improving the flexibility and convenience of the screw gate hoist during use.

[0025] Reference Figure 2-4 As shown in this embodiment: a protruding ring 287 is fixedly connected to one end of the plug 286. The protruding ring 287 is made of rubber. When the plug 286 is inserted into the oil filling tube 281, it will squeeze the protruding ring 287. The protruding ring 287 can tighten the position of the plug 286 inside the oil filling tube 281, improving the tightness of the plug 286 when it is inserted into the oil filling tube 281 to seal the oil filling tube 281. An elastic rope 288 is fixedly connected to one side of the mounting block 21. The end of the elastic rope 288 away from the mounting block 21 is fixedly connected to one side of the plug 286. When the plug 286 is pulled out of the oil filling tube 281 for oil filling, the elastic rope 288 can temporarily fix the plug 286 to one side of the mounting block 21, making it easy to pick up and use and preventing the plug 286 from being lost.

[0026] Working principle: When installing the screw gate hoist, place the base 1 at the top of the valve and fix the base 1 in place using bolts or other fasteners through the pre-drilled holes at the four corners. Then, pass the screw connected to the valve through the threaded groove 4 inside the housing 3 (the installation of the screw gate hoist is a well-known technique and will not be described in detail here). Subsequently, add lubricating oil into the rectangular groove 282 through the oil supply pipe 285 at the top of the mounting block 21. After adding the oil, insert the plug 286 into the oil supply pipe 281. After installation, the lubricating oil will enter the rectangular groove 282 and then enter the sponge block 284. The sponge block 284 will absorb the lubricating oil. The lubricating oil absorbed inside the sponge block 284 will seep out over time and enter the housing 3 through the oil supply pipe 285 to lubricate the inner wall of the housing 3 and the outer surface of the screw. The ends of the sealing blocks 23 at the top of the two mounting blocks 21 that are close to each other will fit tightly against the outer surface of the screw. The screw is sealed above the contact point between the screw and the top of the internal threaded groove 4 of the housing 3. When using the screw hoist, the two sealing blocks 23 are pulled from the top of the two mounting blocks 21 respectively. The two sealing blocks 23 slide on the inner wall of the sliding groove 22 at the top of the mounting block 21 through the bottom protrusion and move away from each other, compressing the spring 24. This makes the two sealing blocks 23 move away from the outer surface of the screw and the side of the positioning rod 27 is attached to the outside of the stop block 25. The operating rod 26 is temporarily fixed at the top of the stop block 25 and the sealing blocks 23 at the top of the mounting block 21. Then, one end of the two handles 5 is inserted into the inner wall of the housing 3 respectively and the handles 5 are rotated to connect with the housing 3 by threads. Pushing the handles 5 controls the rotation of the housing 3 so that the screw drives the valve to rise and fall. After the screw hoist is used, the sealing blocks 23 are released and the spring 24 returns to its original state, which will push the two sealing blocks 23 closer to each other and attach them to the outer surface of the screw again to seal the outside of the screw.
