Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically a multi-directional clamp for electromechanical equipment. Background Technology

[0002] Electromechanical equipment is a type of equipment that integrates mechanical, electrical, electronic, and electromagnetic technologies. It is widely used in many fields such as industrial production, transportation, commercial services, and residential life. It is an indispensable tool for modern social production and life. In the vast system of electromechanical equipment, fans, as common fluid machinery, play a key role in scenarios such as air transportation, ventilation, and cooling, and have become an important part of the electromechanical equipment field.

[0003] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas. It belongs to driven fluid machinery and has a wide range of applications. A fan is mainly composed of impeller, casing, air inlet, support, motor, transmission components and other components. These components work together to achieve efficient gas transportation. At present, in the production process of axial flow fans, operators generally use hydraulically driven clamping plates to fix and clamp the fan casing and pipes, thereby installing components such as fan blades and motors into the axial flow fan.

[0004] However, this traditional clamping method has obvious drawbacks. Due to its fixed clamping mode, the axial flow fan cannot rotate freely while clamped. When it is necessary to operate the axial flow fan at different angles and adjust it to the appropriate installation angle, this clamping method is difficult to meet the requirements. This results in inconvenient and inefficient operation during the installation of the axial flow fan, and increases the difficulty and time cost of personnel assembling and installing it. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-directional clamp for electromechanical equipment to solve the technical problem that the existing hydraulically driven clamping method causes the axial flow fan to be unable to rotate at an angle in the clamping state.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-directional clamp for electromechanical equipment, comprising a fixing machine and a fan pipe. A first rotating ring and a second rotating ring are respectively installed on both sides of the fixing machine. Three sets of drive rods are provided inside the first rotating ring and the second rotating ring. One end of each drive rod is connected to a fixed column, and one end of the fixed column is fixedly connected to the outer wall of one side of the fixing machine. A clamping roller is movably installed at the end of the drive rod. A drive frame is sleeved on the outer wall of the drive rod, and the drive frame is movably connected to the first rotating ring. A rotating handle is fixed on the outer wall of the first rotating ring, and an anti-rotation valve is movably connected to the top of the rotating handle. A groove is provided on the top of the fixing machine.

[0007] By adopting the above technical solution, the problem that the existing hydraulically driven clamping method prevents the axial flow fan from rotating at an angle while clamped is solved. The fan tube is placed inside the fixed machine, and the operator rotates the first rotating ring by turning the handle. This causes the first and second rotating rings to rotate at an angle around the fixed column by three sets of drive frames that are movably set on the inner wall. This causes the ends of the three sets of drive rods to rotate closer together, thereby clamping the outer wall of the fan tube with the clamping rollers set at the ends of the three sets of drive rods. The clamping rollers are movably installed at the ends of the drive rods, allowing the fan tube to rotate while clamped, thus facilitating the operator to adjust the rotation of the fan tube.

[0008] The present invention is further configured such that a connecting block is fixed to the outer wall of the first rotating ring, and one end of the connecting block is connected to the second rotating ring, wherein the connecting block is configured as a U-shape.

[0009] Preferably, since the first rotating ring and the second rotating ring are connected by a U-shaped connecting block, when the first rotating ring rotates, the second rotating ring can rotate synchronously with the first rotating ring.

[0010] The present invention is further configured such that both ends of the clamping roller penetrate the inner wall of the drive rod, a slot is provided on one side of the clamping roller, a fixing rod is fixed on one side of the first rotating ring, a support column is provided on the outer wall of the fixing rod, an anti-rotation device is sleeved on the outer wall of the support column, and three sets of anti-rotation columns are installed on one side of the anti-rotation device.

[0011] Preferably, after the fan pipe is clamped and fixed, the fan pipe is rotated to a suitable angle, and then the anti-rotation device is rotated and adjusted so that the three sets of anti-rotation columns on one side of the anti-rotation device are aligned with the slots on one side of the three sets of clamping rollers. Then the anti-rotation device is pushed towards the fan pipe, and the anti-rotation columns are inserted into the slots on one side of the clamping rollers, so that the three sets of clamping rollers cannot easily rotate.

[0012] The present invention is further configured such that the anti-rotation post is a hexagonal prism and the inner wall of the slot is hexagonal.

[0013] Preferably, the anti-rotation post limits the rotation angle of the clamping roller, so that when the anti-rotation post is inserted into the slot inside the clamping roller, the clamping roller cannot rotate.

[0014] The present invention is further configured such that a retaining plate is movably installed on the outer wall of the anti-rotation device, and a retaining block is provided on one side of the first rotating ring.

[0015] Preferably, when the anti-rotation post is inserted into the slot, the locking plate on one side of the anti-rotation device is rotated so that the end of the locking plate is engaged with the locking block, so that the anti-rotation device will not slide freely on the support post.

[0016] The present invention is further configured such that both the card plate and the card block are L-shaped, and the width of the inner wall of the card block is greater than the width of one end of the card plate.

[0017] Preferably, the L-shaped end of the card plate is secured with a locking block to prevent the card plate from moving horizontally.

[0018] The present invention is further provided that the outer wall of the clamping roller is fitted with a rubber sleeve.

[0019] Preferably, the outer wall of the clamping roller is wrapped with a rubber sleeve, which can reduce the clamping damage of the clamping roller to the outer wall of the fan pipe, and increase the friction between the clamping roller and the fan pipe, thereby reducing the fan pipe from rotating and slipping during processing.

[0020] The present invention is further configured such that the distance between the clamping rollers inside the first rotating ring and the second rotating ring is greater than half the length of the fan pipe and less than the total length of the fan pipe.

[0021] Preferably, the clamping rollers inside the first and second rotating rings can provide good support for the entire fan pipe, thereby enabling the fan pipe to be stably clamped and fixed inside the machine.

[0022] In summary, the present invention has the following main advantages: 1. This utility model solves the problem that existing hydraulically driven clamping methods prevent axial flow fans from rotating at an angle while clamped by setting up a fixing machine, a first rotating ring, a second rotating ring, a connecting block, a fixing column, a drive rod, a drive frame, and clamping rollers. The fan pipe is placed inside the fixing machine, and the operator rotates the first rotating ring by turning the handle. This causes the first and second rotating rings to rotate at an angle around the fixing column by three sets of drive frames that are movably set on the inner wall. This causes the ends of the three sets of drive rods to rotate closer together, thereby clamping the outer wall of the fan pipe with clamping rollers set at the ends of the three sets of drive rods. The clamping rollers are movably installed at the ends of the drive rods, allowing the fan pipe to rotate while clamped, thus facilitating the operator's rotation adjustment.

[0023] 2. This utility model, by setting up an anti-rotation device, anti-rotation column, support column, fixing rod and slot, after the fan pipe is clamped and fixed, rotates the fan pipe to a suitable angle, and then rotates and adjusts the anti-rotation device so that the three sets of anti-rotation columns on one side of the anti-rotation device are aligned with the slots on one side of the three sets of clamping rollers. Then, the anti-rotation device is pushed towards the fan pipe, and the anti-rotation column is inserted into the slot on one side of the clamping roller, so that the three sets of clamping rollers cannot easily rotate.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] First embodiment: Please see Figure 1 — Figure 5The device includes a fixed unit 1 and a fan pipe 5. A first rotating ring 2 and a second rotating ring 201 are respectively installed on both sides of the fixed unit 1. Each of the first and second rotating rings 201 has three sets of drive rods 301 inside. One end of each drive rod 301 is connected to a fixed column 3, and one end of the fixed column 3 is fixedly connected to the outer wall of one side of the fixed unit 1. A clamping roller 303 is movably installed at the end of each drive rod 301. A drive frame 302 is fitted onto the outer wall of the drive rod 301 and is movably connected to the first rotating ring 2. A handle 203 is fixed to the outer wall of the first rotating ring 2, and a stop valve 204 is movably connected to the top of the handle 203. A groove 205 is provided on the top of the fixed unit 1, which solves the problem of existing hydraulic drives... The problem caused by the dynamic clamping method is that the axial flow fan cannot rotate in the clamped state. The fan pipe 5 is placed inside the fixed machine 1. The operator rotates the first rotating ring 2 by the handle 203. The first rotating ring 2 and the second rotating ring 201 drive the three sets of driving rods 301 around the fixed column 3 by the three sets of driving frames 302 that are movably set on the inner wall. This causes the ends of the three sets of driving rods 301 to rotate closer together, so that the clamping rollers 303 set at the ends of the three sets of driving rods 301 clamp the outer wall of the fan pipe 5. The clamping rollers 303 are movably installed at the ends of the driving rods 301, so that the fan pipe 5 can rotate in the clamped state, which makes it convenient for the operator to adjust the rotation of the fan pipe 5.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 A connecting block 202 is fixed to the outer wall of the first rotating ring 2, and one end of the connecting block 202 is connected to the second rotating ring 201. The connecting block 202 is U-shaped. Since the first rotating ring 2 and the second rotating ring 201 are connected by the U-shaped connecting block 202, when the first rotating ring 2 rotates, the second rotating ring 201 can rotate synchronously with the first rotating ring 2.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The clamping roller 303 has two ends that pass through the inner wall of the drive rod 301. A slot 304 is provided on one side of the clamping roller 303. A fixing rod 403 is fixed on one side of the first rotating ring 2. A support column 402 is provided on the outer wall of the fixing rod 403. An anti-rotation device 4 is sleeved on the outer wall of the support column 402. Three sets of anti-rotation columns 401 are installed on one side of the anti-rotation device 4. After the fan pipe 5 is clamped and fixed, the fan pipe 5 is rotated to a suitable angle. Then the anti-rotation device 4 is rotated and adjusted so that the three sets of anti-rotation columns 401 on one side of the anti-rotation device 4 are angularly aligned with the slots 304 on one side of the three sets of clamping rollers 303. Then the anti-rotation device 4 is pushed towards the fan pipe 5, and the anti-rotation columns 401 are inserted into the slots 304 on one side of the clamping roller 303, so that the three sets of clamping rollers 303 cannot easily rotate.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The anti-rotation post 401 is set as a hexagonal prism, and the inner wall of the slot 304 is set as a hexagon. The anti-rotation post 401 limits the rotation angle of the clamping roller 303, so that when the anti-rotation post 401 is inserted into the slot 304 inside the clamping roller 303, the clamping roller 303 cannot rotate.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The outer wall of the anti-rotation device 4 is movably fitted with a clamping plate 404, and a clamping block 405 is provided on one side of the first rotating ring 2. When the anti-rotation column 401 is inserted into the clamping groove 304, the clamping plate 404 on one side of the anti-rotation device 4 is rotated so that the end of the clamping plate 404 is engaged with the clamping block 405, so that the anti-rotation device 4 will not slide freely on the support column 402.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 Both the card plate 404 and the card block 405 are L-shaped. The width of the inner wall of the card block 405 is greater than the width of one end of the card plate 404. The L-shaped end of the card plate 404 is fastened to the card block 405, so that the card plate 404 will not move horizontally.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The outer wall of the clamping roller 303 is covered with a rubber sleeve. The rubber sleeve can reduce the clamping damage of the clamping roller 303 to the outer wall of the fan pipe 5, and increase the friction between the clamping roller 303 and the fan pipe 5, thereby reducing the rotational slippage of the fan pipe 5 during processing.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 3 The distance between the clamping rollers 303 inside the first rotating ring 2 and the second rotating ring 201 is greater than half the length of the fan pipe 5 and less than the total length of the fan pipe 5. The clamping rollers 303 inside the first rotating ring 2 and the second rotating ring 201 can provide good support for the fan pipe 5 as a whole, so that the fan pipe 5 can be stably clamped and fixed inside the machine 1.

[0036] Second embodiment: Please see Figure 6A placement platform 6 is provided at the bottom of the inner wall of the fixing machine 1. The height of the placement platform 6 is less than the radius of the inner wall of the fixing machine 1. The top wall of the placement platform 6 is arc-shaped. Before the clamping roller 303 clamps the fan pipe 5, the fan pipe 5 can be placed on the placement platform 6. This allows the personnel to suspend the fan pipe 5 inside the fixing machine 1 with just one hand. Since the outer diameter of the fan pipe 5 is 300mm and the thickness is 0.6mm, the fan pipe 5 is relatively light. When the personnel turn the handle 203, the resistance of the fan pipe 5 to the clamping rollers 303 located on both sides of the bottom of the fan pipe 5 is small, so that the personnel can easily turn the handle 203.

[0037] In practical operation, the fan pipe 5 made of aluminum plate to be processed has an outer diameter of 300mm and a thickness of 0.6mm. First, the operator inserts the fan pipe 5 into the center of the fixing machine 1, so that the outer wall of the fan pipe 5 is located in the clamping area inside the first rotating ring 2 and the second rotating ring 201. Then, the operator rotates the first rotating ring 2 counterclockwise using the handle 203. Since the first rotating ring 2 and the second rotating ring 201 are connected by a U-shaped connecting block 202, the second rotating ring 201 and... The first rotating ring 2 rotates synchronously. When the first rotating ring 2 rotates, it drives the three sets of driving rods 301 to rotate around the fixed column 3 via three sets of driving frames 302 movably arranged on the inner wall. The driving frames 302 slide along the driving rods 301 towards the fixed column 3, causing the ends of the three sets of driving rods 301 to rotate closer together. This causes the clamping rollers 303 at the ends of the three sets of driving rods 301 to clamp the outer wall of the fan pipe 5. Since the second rotating ring 201 rotates synchronously with the first rotating ring 2, ... Therefore, the three sets of clamping rollers 303 inside the second rotating ring 201 also clamp the outer wall of the fan pipe 5, thereby stably clamping and fixing the fan pipe 5 inside the fixing machine 1. When the three sets of clamping rollers 303 have completed clamping and fixing the fan pipe 5, the anti-rotation valve 204 at the top of the rotating handle 203 is rotated and inserted into the groove 205 at the top of the fixing machine 1. The fixing machine 1, through the fixing of the anti-rotation valve 204 and the rotating handle 203, prevents the first rotating ring 2 and the second rotating ring 201 from rotating. Then, the fan pipe 5 is rotated to a suitable angle, and then... Rotate the anti-rotation device 4 to align the three anti-rotation pillars 401 on one side of the anti-rotation device 4 with the slots 304 on one side of the three clamping rollers 303. Then push the anti-rotation device 4 towards the fan pipe 5. Insert the anti-rotation pillars 401 into the slots 304 on one side of the clamping rollers 303, so that the three clamping rollers 303 cannot easily rotate. Finally, rotate the clamping plate 404 on one side of the anti-rotation device 4 so that the end of the clamping plate 404 is engaged with the L-shaped clamping block 405, so that the anti-rotation device 4 will not slide freely on the support pillar 402.
