Description

Technical Field

[0001] This utility model relates to the technical field of gate opening and closing equipment, specifically to a portable mechanical device for opening and closing gates. Background Technology

[0002] In the field of water conservancy, gate control plays a crucial role in regulating water flow, controlling water levels, and ensuring the safe operation of facilities. Traditional gate opening and closing methods mainly rely on manual operation, which has significant limitations. Manually operating gates is extremely labor-intensive. Operators need to use simple tools, such as wrenches, to directly act on the valve stem and manually turn the stem to open or close the gate. Opening and closing valves outdoors and on roads can take 4-6 people several tens of minutes to complete manually. This not only consumes a lot of manpower but is also inefficient. In some emergency situations, manual operation often cannot meet the timeliness requirements.

[0003] Therefore, large, fixed equipment is used for opening and closing gates. While this equipment can achieve a large torque output and is suitable for opening and closing large and heavy gates, it is also bulky, complex in structure, and expensive to install and maintain. Furthermore, its fixed installation in a specific location lacks flexibility, making it impossible to quickly move to other gates requiring operation, and limiting its ability to operate gates in different locations or of different models.

[0004] Therefore, this utility model proposes a portable mechanical device for opening and closing gates to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a portable mechanical device for opening and closing gates, which solves the problems of existing technologies that cannot perform rapid position transfer, cannot be applied to the opening and closing of gates of various diameters, and have limitations.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A portable gate opening and closing mechanical device includes a fixed base, a lifting assembly connected to the bottom of the fixed base, a mechanical housing connected to the upper end of the fixed base, an output shaft rotatably connected to the upper end of the mechanical housing, a valve stem sleeve coaxially and longitudinally slidably connected inside the output shaft, a plurality of limit blocks evenly connected along the circumference of the bottom of the valve stem sleeve, and a limit groove corresponding to the limit blocks on the output shaft; a drive motor is connected to one side of the mechanical housing, and the drive motor is connected to the output shaft through a bevel gear assembly disposed inside the mechanical housing; a handheld device is also disposed inside the mechanical housing, and an operation display screen is connected to the mechanical housing and electrically connected to the handheld device; a torque sensor is disposed inside the mechanical housing corresponding to the output shaft, and the torque sensor is electrically connected to the operation display screen.

[0008] By adopting the above technical solution, the device can be moved quickly to adapt to valves of different sizes.

[0009] Furthermore, the lifting assembly includes a top plate, a bottom plate, a first connecting rod, and a second connecting rod. Both the first connecting rod and the second connecting rod are rotatably connected to the top plate. The end of the first connecting rod away from the top plate is rotatably connected to a first slider, and the end of the second connecting rod away from the top plate is rotatably connected to a second slider. Both the first slider and the second slider are slidably connected to the bottom plate. A bidirectional lead screw is rotatably connected inside the bottom plate. Both the first slider and the second slider are threadedly connected to the bidirectional lead screw. A rotating handle is connected to the end of the bidirectional lead screw.

[0010] By adopting the above technical solution, it is possible to adapt to gate valve stems of different heights.

[0011] Furthermore, a waterproof cover is connected between the bottom plate and the top plate, and the waterproof cover is corrugated.

[0012] By adopting the above technical solution, the waterproof cover can prevent water and other impurities from entering the lifting component, and can also extend and retract with the lifting of the top plate.

[0013] Furthermore, a plurality of leveling rods are connected between the fixed base and the top plate. The leveling rod includes a support rod, a first support seat and a second support seat. The first support seat is ball-jointed to the fixed base, and the second support seat is fixedly connected to the top plate. The second support seat is internally threaded with a support rod, and a nut is connected to the support rod. The support rod is rotatably connected to the first support seat, and a scale is provided on the outer side of the support rod.

[0014] Furthermore, a level is fixedly connected to the upper surface of the fixed base.

[0015] By adopting the above technical solution, the relative angle between the fixed base and the top plate can be adjusted by observing the level on the upper surface of the fixed base, so that the fixed base can be adjusted to a horizontal state, and the scale on the leveling rod can assist in the adjustment.

[0016] Furthermore, an audible and visual alarm is installed inside the mechanical housing, and the audible and visual alarm is electrically connected to the torque sensor.

[0017] By adopting the above technical solution, when the torque value detected by the torque sensor exceeds the set range, the torque sensor transmits the signal to the audible and visual alarm, which then emits audible and visual signals to remind the operator to handle the abnormal situation in a timely manner and avoid equipment damage.

[0018] Furthermore, the valve stem sleeve has anti-slip textures evenly distributed on its sidewalls, and the bottom of the output shaft has a groove along its circumference corresponding to the limiting block.

[0019] By adopting the above technical solution, the anti-slip texture on the side wall of the valve stem sleeve can increase friction, making it easier to pick up the output shaft; by rotating the valve stem sleeve, the limiting block slides along the groove at the bottom of the output shaft, which can ensure a stable connection.

[0020] Furthermore, the top periphery of the fixed base is inclined.

[0021] By adopting the above technical solution, drainage can be completed quickly, avoiding water accumulation.

[0022] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model involves coaxially sliding the valve stem sleeve longitudinally into the output shaft, thereby moving the device to the gate valve stem position, aligning the valve stem sleeve with the valve stem, and pushing the valve stem sleeve downwards until the valve stem is inserted into the valve stem sleeve. The drive motor is then activated, and the drive motor drives the output shaft to rotate via the bevel gear assembly in the mechanical housing, thereby driving the gate valve stem to rotate, realizing the opening and closing operation of the gate. This allows for rapid device movement and adaptability to valves of different sizes.

[0024] 2. This utility model can set the torque for valves of different diameters through the operation display screen, and then control the motor data through the hand controller to change the torque to open and close the valve, thereby completing the opening and closing, protecting the valve opening and closing shaft from being broken and ensuring fast and safe operation.

[0034] like Figure 1-4As shown, a portable gate opening and closing mechanical device includes a fixed base 1, the top periphery of which is inclined. A lifting assembly is connected to the bottom of the fixed base 1, and a mechanical box 3 is connected to the upper end of the fixed base 1. An output shaft 4 is rotatably connected to the upper end of the mechanical box 3. A valve stem sleeve 5 is coaxially and longitudinally slidably connected inside the output shaft 4. Multiple limiting blocks 8 are evenly connected to the bottom periphery of the valve stem sleeve 5, and the output shaft 4 has limiting grooves 9 corresponding to the limiting blocks 8. Anti-slip textures 6 are evenly provided on the side wall of the valve stem sleeve 5, and a sliding groove 7 is provided on the bottom periphery of the output shaft 4 corresponding to the limiting blocks 8. A drive motor 10 is connected to one side of the mechanical housing 3. The drive motor 10 is connected to the output shaft 4 via a bevel gear assembly 11, which is located inside the mechanical housing 3. A handheld device 12 is also located inside the mechanical housing 3, and an operation display screen 13 is connected to the mechanical housing 3. The operation display screen 13 is electrically connected to the handheld device 12. A torque sensor 14 is located inside the mechanical housing 3 corresponding to the output shaft 4, and the torque sensor 14 is electrically connected to the operation display screen 13. An audible and visual alarm 15 is located inside the mechanical housing 3, and the audible and visual alarm 15 is electrically connected to the torque sensor 14.

[0035] like Figure 5 and Figure 6 As shown, the lifting assembly includes a top plate 16, a bottom plate 17, a first connecting rod 18, and a second connecting rod 19. Both the first connecting rod 18 and the second connecting rod 19 are rotatably connected to the top plate 16. The end of the first connecting rod 18 away from the top plate 16 is rotatably connected to the first slider 20, and the end of the second connecting rod 19 away from the top plate 16 is rotatably connected to the second slider 21. Both the first slider 20 and the second slider 21 are slidably connected to the bottom plate 17. A bidirectional lead screw 22 is rotatably connected inside the bottom plate 17. Both the first slider 20 and the second slider 21 are threadedly connected to the bidirectional lead screw 22. A rotating handle is connected to the end of the bidirectional lead screw 22. A waterproof cover 23, which is corrugated, is connected between the bottom plate 17 and the top plate 16.

[0036] Multiple leveling rods are connected between the fixed base 1 and the top plate 16. Each leveling rod includes a support rod 24, a first support seat 27, and a second support seat 28. The first support seat 27 is ball-jointed to the fixed base 1, and the second support seat 28 is fixedly connected to the top plate 16. The second support seat 28 is internally threaded with the support rod 24, and a nut 26 is attached to the support rod 24. The support rod 24 is rotatably connected to the first support seat 27. A graduated scale 25 is provided on the outer side of the support rod 24. A level 2 is fixedly connected to the upper surface of the fixed base 1.

[0037] The working process of this utility model is as follows:

[0038] First, rotate the handle at the end of the bidirectional lead screw 22 on the base plate 17 of the lifting assembly. As the bidirectional lead screw 22 rotates, the first slider 20 and the second slider 21 are threadedly connected to the bidirectional lead screw 22 and slidably connected to the base plate 17. Therefore, the first slider 20 and the second slider 21 will move relative to or away from each other along the rotation direction of the bidirectional lead screw 22. The first connecting rod 18 and the second connecting rod 19 are rotatably connected to the top plate 16 and the first slider 20 and the second slider 21, respectively. As the sliders move, the first connecting rod 18 and the second connecting rod 19 drive the top plate 16 to rise or fall, thereby adapting to the gate valve stem at different heights.

[0039] Then observe the level 2 on the upper surface of the fixed base 1. By rotating the nut 26 on the leveling rod, the support rod 24 rotates and moves up and down within the first support seat 27, thereby adjusting the relative angle between the fixed base 1 and the top plate 16 and adjusting the fixed base 1 to a horizontal state. The scale 25 on the leveling rod can assist in the adjustment.

[0040] The valve stem sleeve 5 is then slid longitudinally coaxially into the output shaft 4. The valve stem sleeve 5 is then rotated, and the limiting block 8 slides along the groove 7 at the bottom of the output shaft 4 to ensure a secure connection. The device is then moved to the gate valve stem position, aligning the valve stem sleeve 5 with the valve stem. The valve stem sleeve 5 is pushed downwards, and the limiting block 8 at the bottom of the valve stem sleeve 5 slides longitudinally along the limiting groove 9 within the output shaft 4 until the valve stem is inserted into the valve stem sleeve 5.

[0041] The drive motor 10 is then activated. The drive motor 10 drives the output shaft 4 to rotate via the bevel gear assembly 11 within the mechanical housing 3. Due to the cooperation between the limit block 8 and the limit groove 9, the rotation of the output shaft 4 causes the valve stem sleeve 5 to rotate as well, thereby driving the gate valve stem to rotate and realizing the opening and closing operation of the gate. Furthermore, based on the principle of the torque formula T = 9550 * P / N, the torque is set on the operation display screen 13 for valves of different diameters. The motor data is then controlled via the handheld device 12 to change the torque and the valve opening / closing force, completing the opening and closing process while ensuring the safety of the valve opening / closing shaft from breakage and enabling fast and safe operation.

[0042] During operation, the torque sensor 14 corresponding to the output shaft 4 inside the mechanical housing 3 monitors the torque on the output shaft 4 in real time and transmits the torque data to the operation display screen 13 for display. When the torque value detected by the torque sensor 14 exceeds the set range, it indicates that an abnormality has occurred in the gate opening and closing process. The torque sensor 14 transmits the signal to the audible and visual alarm 15, which emits an audible and visual signal to remind the operator to deal with the abnormality in time and avoid equipment damage.
