Description

Technical Field

[0001] The utility model relates to the technical field of anti-reversal, in particular to an anti-reversal device for a motor. Background Art

[0002] Motors are an important part of modern technology and are widely used in various fields, such as industry, transportation, and medical treatment. The main function of motors is to convert electrical energy into mechanical energy to drive various devices. Current motors can control the forward and reverse rotation of motors by controlling the phase reversal of the circuit, but in some scenarios, motor reversal is not allowed, such as escalators or special equipment. If the motor reverses, accidents may occur. It can be seen that anti-reversal of motors is very important.

[0003] The anti-reversal of the motor can be controlled by the circuit, but if the circuit is misphased or broken, the anti-reversal capability will no longer be available, and when the circuit loses pressure, the motor's torque may be insufficient, making it impossible to complete the anti-reversal operation. The prior art will cause the lubricating oil to gradually age after being used for too long. Continuing to use it will increase the wear of internal components, and the prior art needs to stop running and disassemble the equipment when adding lubricating oil. Utility Model Content

[0004] The purpose of the utility model is to provide a motor anti-reverse device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses an anti-reversal device for a motor, comprising a main body bottom shell, the top of the main body bottom shell is rotatably connected to a main body upper shell, the top of the main body bottom shell is fixedly connected to an anti-reversal ratchet, the outer wall of the anti-reversal ratchet is slidably connected to an anti-reversal clamping ball, and there are multiple groups of anti-reversal clamping balls, the outer wall of each group of anti-reversal clamping balls is slidably connected to the inner wall of the main body upper shell, the outer wall of the anti-reversal clamping balls is fixedly connected to a lubrication mechanism, and there are multiple groups of lubrication mechanisms, and the bottom of the main body bottom shell is fixedly connected to a clamping mechanism, and there are two groups of clamping mechanisms.

[0007] Each group of the lubrication mechanisms includes a force-bearing top plate, the inner wall of the force-bearing top plate is fixedly connected to the outer wall of the anti-reversal ball, the outer wall of the force-bearing top plate is slidably connected to the inner wall of the main body upper shell, the inner wall of the force-bearing top plate is fixedly connected to an oil pipeline, the outer wall of the force-bearing top plate is overlapped with an airbag, the inner wall of the airbag is slidably connected to the outer wall of the oil pipeline, the outer wall of the airbag is fixedly connected to the inner wall of the main body upper shell, one end of the airbag is fixedly connected to a fixed bin, the inner wall of the fixed bin is slidably connected to an oil inlet block, and the outer wall of the oil inlet block is provided with an oil inlet hole.

[0008] By adopting the above technical solution, when the motor body is turned off or insufficient torque is caused by unstable voltage, the gravity of the external device may cause the motor body to reverse. At this time, the motor body will drive the upper shell of the main body to reverse. When the upper shell of the main body reverses, it will push the anti-reversal ball to move, and the anti-reversal ball will be stuck with the anti-reversal ratchet. At this time, the anti-reversal effect can be achieved. When the equipment is operating normally, the upper shell of the main body will push the anti-reversal ball to slide on the outer wall of the anti-reversal ratchet, and the anti-reversal ball will make repeated up and down movements. When the anti-reversal ball moves upward, it will push the force-bearing top plate to move upward, and the force-bearing top plate will move upward. The airbag will be squeezed during movement. Since the airbag is fixed on the inner wall of the upper shell of the main body, the squeezing of the force-bearing top plate will not move the airbag, but will change the shape of the airbag. When the shape of the airbag changes, it will enter the inner wall of the fixed bin and push the oil inlet block to move upward. At this time, the oil inlet hole opened on the outer wall of the oil inlet block can pour the lubricating oil into the interior, and the lubricating oil will flow to the anti-reverse ball through the oil pipe. Since the anti-reverse ball is constantly rotating, the outer wall of the anti-reverse ball will always maintain a layer of oil film, which will not only spread the lubricating oil to the outer wall of the anti-reverse ratchet, but also reduce the friction between the anti-reverse ball and the anti-reverse ratchet.

[0009] Furthermore, each group of the clamping mechanisms includes a reset bin, the top of the reset bin is fixedly connected to the bottom of the main body bottom shell, the inner wall of the reset bin is fixedly connected to a reset spring, one end of the reset spring is fixedly connected to a clamping block, and the outer wall of the clamping block is slidably connected to the inner wall of the reset bin.

[0010] By adopting the above technical solution, when installing the motor body, the motor body can be directly pushed into the interior of the main body bottom shell. Since the clamping block is designed with an oblique mouth, the clamping block will be squeezed by the motor body into the interior of the reset chamber. When the motor body is fully entered, the clamping block will be reset outward by the force of the reset spring, and the clamping block can clamp the motor body after resetting to prevent the motor body from falling off.

[0011] Furthermore, an outer wall of the main body upper shell is slidably connected to an oil tank, a slider is provided at the bottom of the oil tank, the slider is slidably connected to the outer wall of the main body upper shell, and an inner wall of the oil tank is slidably connected to an outer wall of the fixed bin.

[0012] By adopting the above technical solution, through the setting of the oil tank, lubricating oil can be added to the oil tank first when it is needed. At this time, the oil inlet block will repeatedly suck the lubricating oil inside the oil tank into it during the movement, and wait for the equipment to operate to automatically spread the lubricating oil evenly. When the upper shell of the main body rotates, the oil tank will not rotate with it, which also makes it convenient for the staff to add lubricating oil during the operation of the equipment.

[0013] Furthermore, a tank cover is fixedly connected to the top of the oil tank, and a handle is fixedly connected to the top of the tank cover.

[0014] By adopting the above technical solution, the setting of the box cover can prevent the lubricating oil from splashing during operation and avoid the waste of lubricating oil. At the same time, the setting of the handle can facilitate the removal of the box cover and the addition of lubricating oil into the box.

[0015] Furthermore, the inner wall of the main body upper shell is fixedly mounted with a motor body, the outer wall of the motor body is rotatably connected to the inner wall of the main body bottom shell, the bottom of the motor body is slidably connected to the top of the clamping block, and the outer wall of the output shaft of the motor body is fixedly connected with a fixing block.

[0016] By adopting the above technical solution, the motor body is installed on the inner wall of the main body upper shell so that it drives the main body upper shell to rotate. At this time, when the main body upper shell rotates forward, it can operate normally. When reverse rotation occurs, the anti-reverse ratchet and the anti-reverse ball will be stuck to prevent the motor body from reversing. Through the setting of the fixed block, the external device can be more firmly fixed to the motor body to prevent the external device from detaching from the motor body.

[0017] Furthermore, a clamping block is fixedly connected to the inner wall of the main body upper shell, the motor body is fixedly installed on the inner wall of the clamping block, a mounting screw is threadedly connected to the inner wall of the clamping block, and the outer wall of the mounting screw is threadedly connected to the inner wall of the motor body.

[0018] By adopting the above technical solution, the motor body can be clamped between the main body upper shell and the clamping block through the setting of the clamping block, so that the motor body can more stably drive the main body upper shell to rotate, and the setting of the mounting screws can make the motor body fixedly installed at the clamping block to prevent the motor body from falling off.

[0019] Furthermore, an outer wall of the main body bottom shell is provided with a mounting hole, and a supporting foot is fixedly connected to the bottom of the main body bottom shell.

[0020] By adopting the above technical solution, the main body bottom shell can be installed on an external device or a wall through the setting of the mounting holes, making the main body bottom shell more stable and preventing the main body bottom shell from moving during the operation of the equipment. The main body bottom shell can also be placed on the ground through the design of the supporting feet and avoid direct contact with the ground, thereby preventing noise and wear caused by vibration during the operation of the equipment.

[0021] Furthermore, a sliding groove is provided at the top of the main body bottom shell, a sliding block is fixedly connected to the bottom of the main body upper shell, and there are multiple groups of sliding blocks, and the outer wall of the sliding block is slidably connected to the inner wall of the sliding groove.

[0022] By adopting the above technical solution, the sliding groove and the sliding block are set to make the sliding between the main body bottom shell and the main body upper shell more stable to avoid falling off, and the sliding groove is opened towards the inner wall of the main body bottom shell. At this time, the setting of the sliding block can also increase the sealing between the main body bottom shell and the main body upper shell to prevent the internal lubricating oil from leaking.

[0023] The utility model has the following beneficial effects:

[0024] 1. When the equipment is operating normally, the upper shell of the main body of the utility model will push the anti-reversal card ball to slide on the outer wall of the anti-reversal ratchet, and the anti-reversal card ball will make repeated up and down movements. When the anti-reversal card ball moves upward, it will push the force-bearing top plate to move upward, and when the force-bearing top plate moves upward, it will squeeze the airbag. Since the airbag is fixed to the inner wall of the upper shell of the main body, the squeezing of the force-bearing top plate will not move the airbag, but will change the shape of the airbag. When the shape of the airbag changes, it will enter the inner wall of the fixed bin and push the oil inlet block to move upward. At this time, the oil inlet hole opened on the outer wall of the oil inlet block can pour the lubricating oil into the interior, and the lubricating oil will flow to the anti-reversal card ball through the oil pipeline. Since the anti-reversal card ball rotates continuously, the outer wall of the anti-reversal card ball will always maintain a layer of oil film, which will not only smear the lubricating oil to the outer wall of the anti-reversal ratchet, but also reduce the friction between the anti-reversal card ball and the anti-reversal ratchet.

[0025] 2. When installing the motor body, the utility model can directly push the motor body toward the inside of the main body bottom shell. Since the clamping block is designed with an oblique mouth, the clamping block will be squeezed by the motor body into the interior of the reset chamber. When the motor body is fully entered, the clamping block will be reset outward by the force of the reset spring, and the clamping block can clamp the motor body after resetting to prevent the motor body from falling off.

[0026] 3. In the utility model, when the motor body is turned off or insufficient torque is caused by unstable voltage, the gravity of the external device may cause the motor body to reverse. At this time, the motor body will drive the upper shell of the main body to reverse. When the upper shell of the main body reverses, it will push the anti-reversal ball to move, and the anti-reversal ball and the anti-reversal ratchet will be stuck, so that the anti-reversal effect can be achieved.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figure 1-Figure 8As shown, the utility model is a motor anti-reversal device, including a main body bottom shell 1, the top of the main body bottom shell 1 is rotatably connected to the main body upper shell 11, the top of the main body bottom shell 1 is fixedly connected to the anti-reversal ratchet 13, the outer wall of the anti-reversal ratchet 13 is slidably connected to the anti-reversal clamping ball 14, and there are multiple groups of anti-reversal clamping balls 14, the outer wall of each group of anti-reversal clamping balls 14 is slidably connected to the inner wall of the main body upper shell 11, the outer wall of the anti-reversal clamping ball 14 is fixedly connected to the lubrication mechanism 2, and there are multiple groups of lubrication mechanisms 2, and the bottom of the main body bottom shell 1 is fixedly connected to the clamping mechanism 3, and there are two groups of the clamping mechanism 3.

[0041] Each group of lubrication mechanisms 2 includes a force-bearing top plate 21, the inner wall of the force-bearing top plate 21 is fixedly connected to the outer wall of the anti-reversal ball 14, the outer wall of the force-bearing top plate 21 is slidably connected to the inner wall of the main body upper shell 11, the inner wall of the force-bearing top plate 21 is fixedly connected to an oil pipeline 22, the outer wall of the force-bearing top plate 21 is overlapped with an air bag 23, the inner wall of the air bag 23 is slidably connected to the outer wall of the oil pipeline 22, the outer wall of the air bag 23 is fixedly connected to the inner wall of the main body upper shell 11, one end of the air bag 23 is fixedly connected to a fixed bin 24, the inner wall of the fixed bin 24 is slidably connected to an oil inlet block 25, and the outer wall of the oil inlet block 25 is provided with an oil inlet hole.

[0042] In this embodiment, when the motor body 15 is turned off or insufficient torque due to unstable voltage may cause the gravity of the external device to cause the motor body 15 to reverse. At this time, the motor body 15 will drive the main body upper shell 11 to reverse. When the main body upper shell 11 reverses, it will push the anti-reversal ball 14 to move, and will cause the anti-reversal ball 14 to be stuck with the anti-reversal ratchet 13. At this time, the anti-reversal effect can be achieved. When the equipment is operating normally, the main body upper shell 11 will push the anti-reversal ball 14 to slide on the outer wall of the anti-reversal ratchet 13, and the anti-reversal ball 14 will make repeated up and down movements. When the anti-reversal ball 14 moves upward, it will push the force-bearing top plate 21 to move upward, and the force-bearing top plate 21 will move upward. The airbag 23 is squeezed. Since the airbag 23 is fixed on the inner wall of the main upper shell 11, the squeezing of the force-bearing top plate 21 will not move the airbag 23, but will change the shape of the airbag 23. When the shape of the airbag 23 changes, it will enter the inner wall of the fixed bin 24 and push the oil inlet block 25 to move upward. At this time, the oil inlet hole opened on the outer wall of the oil inlet block 25 can pour the lubricating oil into the interior, and the lubricating oil will flow to the anti-reversal ball 14 through the oil pipe 22. Since the anti-reversal ball 14 rotates continuously, the outer wall of the anti-reversal ball 14 will always maintain a layer of oil film. This layer of oil film will not only apply the lubricating oil to the outer wall of the anti-reversal ratchet 13, but also reduce the friction between the anti-reversal ball 14 and the anti-reversal ratchet 13.

[0043] Specifically, each group of clamping mechanisms 3 includes a reset bin 31, the top of the reset bin 31 is fixedly connected to the bottom of the main body bottom shell 1, the inner wall of the reset bin 31 is fixedly connected to a reset spring 32, one end of the reset spring 32 is fixedly connected to a clamping block 33, and the outer wall of the clamping block 33 is slidably connected to the inner wall of the reset bin 31.

[0044] In this embodiment, when installing the motor body 15, the motor body 15 can be directly pushed into the interior of the main body bottom shell 1. Since the clamping block 33 is designed with an oblique mouth, the clamping block 33 will be squeezed by the motor body 15 into the interior of the reset chamber 31. When the motor body 15 is fully entered, the clamping block 33 will be reset outward by the force of the reset spring 32, and the clamping block 33 can clamp the motor body 15 after resetting to prevent the motor body 15 from falling off.

[0045] Specifically, the outer wall of the main upper shell 11 is slidably connected to the oil tank 16 , a slider is provided at the bottom of the oil tank 16 , the slider is slidably connected to the outer wall of the main upper shell 11 , and the inner wall of the oil tank 16 is slidably connected to the outer wall of the fixed bin 24 .

[0046] In this embodiment, through the setting of the oil tank 16, the oil tank 16 can be added first when lubricating oil is needed. At this time, the oil inlet block 25 will repeatedly suck the lubricating oil inside the oil tank 16 into it during the movement, and wait for the equipment to operate to automatically spread the lubricating oil evenly. When the main body upper shell 11 rotates, the oil tank 16 will not rotate with it, which also makes it convenient for the staff to add lubricating oil during the operation of the equipment.

[0047] Specifically, a tank cover 17 is fixedly connected to the top of the oil tank 16 , and a handle is fixedly connected to the top of the tank cover 17 .

[0048] In this embodiment, the provision of the box cover 17 can prevent the lubricating oil from splashing out during operation, thereby avoiding waste of the lubricating oil. Meanwhile, the provision of the handle can facilitate the removal of the box cover 17 and also facilitate personnel to add lubricating oil into the box.

[0049] Specifically, the inner wall of the main upper shell 11 is fixedly mounted with the motor body 15, the outer wall of the motor body 15 is rotatably connected to the inner wall of the main bottom shell 1, the bottom of the motor body 15 is slidably connected to the top of the clamping block 33, and the outer wall of the output shaft of the motor body 15 is fixedly connected with a fixing block.

[0050] In this embodiment, the motor body 15 is installed on the inner wall of the main body upper shell 11 so that it drives the main body upper shell 11 to rotate. At this time, when the main body upper shell 11 rotates forward, it can operate normally. When it rotates reversely, the anti-reverse ratchet 13 and the anti-reverse ball 14 will be stuck to prevent the motor body 15 from reversing. Through the setting of the fixing block, the external device can be more firmly fixed to the motor body 15 to prevent the external device from detaching from the motor body 15.

[0051] Specifically, the inner wall of the main upper shell 11 is fixedly connected with a clamping block 12, the inner wall of the clamping block 12 is fixedly installed with a motor body 15, the inner wall of the clamping block 12 is threadedly connected with a mounting screw, and the outer wall of the mounting screw is threadedly connected to the inner wall of the motor body 15.

[0052] In this embodiment, the motor body 15 can be clamped between the main body upper shell 11 and the clamping block 12 through the setting of the clamping block 12, so that the motor body 15 can more stably drive the main body upper shell 11 to rotate, and the setting of the mounting screws can make the motor body 15 fixedly installed at the clamping block 12 to prevent the motor body 15 from falling off.

[0053] Specifically, an outer wall of the main body bottom shell 1 is provided with a mounting hole, and a supporting foot is fixedly connected to the bottom of the main body bottom shell 1 .

[0054] In this embodiment, the main body bottom shell 1 can be installed on an external device or a wall by setting the mounting holes, making the main body bottom shell 1 more stable and preventing the main body bottom shell 1 from moving during the operation of the device. The main body bottom shell 1 can also be placed on the ground by the design of the supporting feet to avoid direct contact with the ground, thereby preventing noise and wear caused by vibration during the operation of the device.

[0055] Specifically, a sliding groove is provided at the top of the main body bottom shell 1, and a sliding block is fixedly connected to the bottom of the main body upper shell 11, and there are multiple groups of sliding blocks, and the outer wall of the sliding block is slidably connected to the inner wall of the sliding groove.

[0056] In this embodiment, the sliding groove and the sliding block are provided to make the sliding between the main body bottom shell 1 and the main body upper shell 11 more stable to avoid falling off, and the sliding groove is opened toward the inner wall of the main body bottom shell 1. At this time, the provision of the sliding block can also increase the sealing between the main body bottom shell 1 and the main body upper shell 11 to prevent the internal lubricating oil from leaking out.

[0057] When in use, first, the motor needs to be installed into the main body bottom shell 1 and the main body upper shell 11. When installing the motor body 15, the motor body 15 can be directly pushed into the inside of the main body bottom shell 1. Since the clamping block 33 is designed with an oblique mouth, the clamping block 33 will be squeezed by the motor body 15 into the interior of the reset chamber 31. When the motor body 15 is fully entered, the clamping block 33 will be reset outward by the force of the reset spring 32, and the clamping block 33 can clamp the motor body 15 after resetting to prevent the motor body 15 from falling off.

[0058] Secondly, when the equipment is operating normally, the main body upper shell 11 will push the anti-reverse card ball 14 to slide on the outer wall of the anti-reverse ratchet 13, and the anti-reverse card ball 14 will make repeated up and down movements. When the anti-reverse card ball 14 moves upward, it will push the force-bearing top plate 21 to move upward, and when the force-bearing top plate 21 moves upward, it will squeeze the airbag 23. Since the airbag 23 is fixed to the inner wall of the main body upper shell 11, the squeezing of the force-bearing top plate 21 will not move the airbag 23, but will change the shape of the airbag 23. When the shape of the airbag 23 changes, it will enter the inner wall of the fixed bin 24 and push the oil inlet block 25 to move upward. At this time, the oil inlet hole opened on the outer wall of the oil inlet block 25 can pour the lubricating oil into the interior, and the lubricating oil will The oil flows to the anti-reversal ball 14 through the oil pipe 22. Since the anti-reversal ball 14 rotates continuously, the outer wall of the anti-reversal ball 14 always maintains a layer of oil film. This layer of oil film not only spreads the lubricating oil to the outer wall of the anti-reversal ratchet 13, but also reduces the friction between the anti-reversal ball 14 and the anti-reversal ratchet 13. Through the setting of the oil tank 16, the oil tank 16 can be added first when the lubricating oil needs to be added. At this time, the oil inlet block 25 will repeatedly suck the lubricating oil inside the oil tank 16 into it during the movement, and wait for the equipment to operate to automatically spread the lubricating oil evenly, and when the main body upper shell 11 rotates, the oil tank 16 will not rotate with it, which is also convenient for the staff to add lubricating oil during the operation of the equipment.

[0059] Finally, the motor body 15 is installed on the inner wall of the main body upper shell 11 to drive the main body upper shell 11 to rotate. At this time, when the main body upper shell 11 rotates forward, it can operate normally. When the motor body 15 is turned off or the torque is insufficient due to voltage instability, the gravity of the external device may cause the motor body 15 to reverse. At this time, the motor body 15 will drive the main body upper shell 11 to reverse. When the main body upper shell 11 reverses, it will push the anti-reversal ball 14 to move, and will cause the anti-reversal ball 14 to be stuck with the anti-reversal ratchet 13. At this time, the anti-reversal effect can be achieved.
