Description

Technical Field

[0001] This application relates to the field of lifting devices, and more specifically, to a portable traction motor lifting device. Background Technology

[0002] Portable traction motor lifting equipment is a lightweight lifting device that integrates a power unit and an adjustable bracket. It is designed for efficient and safe material handling and traction operations. Its core design concept is "portability". The equipment is small in size and light in weight, and supports quick disassembly, folding or modular assembly, making it easy for a single person to carry and move across different scenarios.

[0003] In the existing technology, portable traction motor lifting devices use electric motors as power sources and achieve vertical lifting or horizontal traction of heavy objects through wire ropes or traction ropes. They are also known as electric hoists.

[0004] However, existing material handling forklifts still have the following shortcomings in use: Existing electric hoists can retract the entire wire rope into the casing, but the hook is usually placed on the outside of the casing, causing the hook to keep swinging when people move the electric hoist, which not only increases people's physical exertion, but also easily causes injury. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a portable traction motor lifting device, which aims to improve the problem that when people carry electric hoists, the hook will keep swaying, which not only increases people's physical exertion but also easily causes injury.

[0006] This application provides a portable traction motor lifting device, including a first housing, an electric hoist is provided inside the first housing, a fixing member is provided on the top of the first housing for fixing the electric hoist in a certain position, a fixing mechanism is provided on the bottom of the first housing for preventing the electric hoist from shaking when people move it, and a disassembly and assembly mechanism is provided on the top of the first housing for disassembling the fixing member.

[0007] The fixing mechanism includes a second housing, a motor is connected to one side of the second housing, the output shaft of the motor passes through the second housing and is connected to a bidirectional screw, and the other end of the bidirectional screw is rotatably connected inside the second housing.

[0008] In one specific implementation, the outer surface of the bidirectional screw is threaded with two sets of threaded seats, the threaded seats are slidably connected inside the second housing, and a protective plate is connected to one side of the threaded seats.

[0009] In the above implementation process, by setting up a bidirectional screw, the output shaft of the motor can be controlled to rotate, which drives the bidirectional screw to rotate inside the second housing, thereby moving the two sets of threaded seats and adjusting the distance between the two sets of threaded seats. The movement of the threaded seats drives the protective plate to move, and the protective plate can prevent the electric hoist hook from causing injury to personnel during the transfer process.

[0010] In one specific implementation, a telescopic rod is connected to one side of the protective plate, a clamp is connected to one end of the telescopic rod, and a first spring is sleeved on the outer surface of the telescopic rod.

[0011] In the above implementation process, by setting the clamps, after the opposite surfaces of the two sets of protective plates come into contact, and at this time the first spring is already in a compressed state, the elastic potential energy released by the first spring can fix the hook of the electric hoist between the two sets of clamps.

[0012] In one specific implementation, the disassembly and assembly mechanism includes two sets of clips, which are respectively connected to both ends of the fixing member, and a through hole is provided on one side of each clip.

[0013] In the above implementation process, by setting the card, the card can be inserted into the card slot, thereby fixing the fastener to the top of the first housing.

[0014] In one specific implementation, the top of the first housing is connected to two sets of mounting members, the top of which has a slot, and the mounting member is movably inserted into the slot.

[0015] In the above implementation process, by setting the mounting part, a slot is opened on the top of the mounting part, so that the card can be movably inserted into the inside of the slot. When the card is inserted into the inside of the slot, the fixing part can be fixed to the top of the first housing. When the card is removed from the inside of the slot, the fixing part can be disassembled.

[0016] In one specific implementation, a third housing is connected to one side of the mounting component, a movable component is slidably connected inside the third housing, a first vertical rod is connected to one side of the movable component, and one end of the first vertical rod passes through the mounting component and is movably inserted into the through hole.

[0017] In the above implementation process, by setting the movable part, the movement of the movable part can be controlled to drive the first vertical rod to move. When the first vertical rod is inserted into the through hole, the first vertical rod can fix the card inside the card slot and play a limiting role for the card. When the first vertical rod is disengaged from the through hole, the limiting role of the first vertical rod on the card can be released, allowing the card to disengage from the card slot.

[0018] In one specific implementation, a second vertical rod is connected to the other side of the movable component, the second vertical rod passing through the third housing and connected to a horizontal plate.

[0019] In the above implementation process, by setting up the horizontal plate, the second vertical rod can be moved by pulling the horizontal plate, thereby moving the moving part and allowing the first vertical rod to disengage from the through hole.

[0020] In one specific implementation, a second spring is fitted onto the outer surface of the second vertical rod.

[0021] In the above implementation process, by setting the second spring, the elastic potential energy can be released by the compression of the second spring, and when the moving part is not subjected to external force, the first vertical rod is always inserted into the through hole by the second spring.

[0022] In one specific implementation, a handle is attached to one side of the first housing.

[0023] In the above implementation process, the handle design makes it easy for people to move the electric hoist by holding the handle. During the transfer, the hook of the electric hoist needs to be fixed inside the protective plate and the fastener needs to be removed. Because the fastener is close to the human body, it needs to be removed to avoid injury to people.

[0024] In one specific implementation, multiple sets of pulleys are connected to the other side of the first housing.

[0025] In the above implementation process, the pulleys facilitate the overall movement of the electric hoist.

[0026] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a fixed mechanism for disassembly and assembly, the protective plate can be moved by controlling the motor, and the hook of the electric hoist can be fixed by the clamp, preventing the hook of the electric hoist from shaking during the transfer. Furthermore, when people use the handle to move the electric hoist as a whole, they need to pull the horizontal plate to disassemble the fixing part. Since the fixing part is close to the person's body, it avoids the fixing part from causing injury to people. This solves the problem that when people carry the electric hoist, the hook will keep shaking, which not only increases the physical exertion of people, but also easily causes injury.

[0037] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Please see Figure 1 This application provides a portable traction motor lifting device, including a first housing 1.

[0039] Please see Figure 1 , Figure 2 and Figure 3An electric hoist 4 is installed inside the first housing 1. A fixing member 6 is provided on the top of the first housing 1 for fixing the electric hoist 4 in a certain position. A fixing mechanism 2 is provided on the bottom of the first housing 1 for preventing the electric hoist 4 from shaking when people move it. A disassembly and assembly mechanism 3 is provided on the top of the first housing 1 for disassembling the fixing member 6.

[0040] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The fixing mechanism 2 includes a second housing 202. A motor 203 is connected to one side of the second housing 202. The output shaft of the motor 203 passes through the second housing 202 and is connected to a bidirectional screw 204. The other end of the bidirectional screw 204 is rotatably connected inside the second housing 202.

[0041] In a specific configuration, the outer surface of the bidirectional screw 204 is threaded with two sets of threaded seats 205. The threaded seats 205 are slidably connected inside the second housing 202. A protective plate 201 is connected to one side of the threaded seats 205. By configuring the bidirectional screw 204, the output shaft of the control motor 203 can rotate, causing the bidirectional screw 204 to rotate inside the second housing 202, which in turn moves the two sets of threaded seats 205, adjusting the distance between the two sets of threaded seats. The movement of the threaded seats 205 moves the protective plate 201, which prevents the hook of the electric hoist 4 from causing injury to personnel during the transfer process.

[0042] In the specific setup, a telescopic rod 206 is connected to one side of the protective plate 201, and a clamping plate 208 is connected to one end of the telescopic rod 206. A first spring 207 is sleeved on the outer surface of the telescopic rod 206. With the clamping plate 208, after the opposing surfaces of the two sets of protective plates 201 come into contact, and the first spring 207 is already in a compressed state, the elastic potential energy released by the first spring 207 fixes the hook of the electric hoist 4 between the two sets of clamping plates 208.

[0043] In a specific configuration, the disassembly and assembly mechanism 3 includes two sets of clips 302, which are respectively connected to both ends of the fixing member 6. One side of the clip 302 has a through hole 303. Through the setting of the clip 302, the clip 302 can be inserted into the inside of the clip slot 305, thereby fixing the fixing member 6 to the top of the first housing 1.

[0044] In a specific configuration, two sets of mounting members 301 are connected to the top of the first housing 1. The top of the mounting member 301 has a slot 305, and the slot 302 is movably inserted into the slot 305. By setting the mounting member 301, the slot 305 on the top of the mounting member 301 allows the slot 302 to be movably inserted into the slot 305. When the slot 302 is inserted into the slot 305, the fixing member 6 can be fixed to the top of the first housing 1. When the slot 302 is removed from the slot 305, the fixing member 6 can be disassembled.

[0045] In a specific configuration, a third housing 306 is connected to one side of the mounting component 301. A movable component 309 is slidably connected inside the third housing 306. A first vertical rod 304 is connected to one side of the movable component 309. One end of the first vertical rod 304 passes through the mounting component 301 and is movably inserted into the through hole 303. By controlling the movement of the movable component 309, the first vertical rod 304 can be moved. When the first vertical rod 304 is inserted into the through hole 303, it can fix the clip 302 inside the slot 305, thus limiting the clip 302. When the first vertical rod 304 is disengaged from the through hole 303, the limiting effect of the first vertical rod 304 on the clip 302 is released, allowing the clip 302 to disengage from the slot 305.

[0046] In a specific configuration, the other side of the movable component 309 is connected to a second vertical rod 308. The second vertical rod 308 passes through the third housing 306 and is connected to a horizontal plate 307. By setting the horizontal plate 307, the second vertical rod 308 can be moved by pulling the horizontal plate 307, thereby moving the movable component 309 and allowing the first vertical rod 304 to disengage from the through hole 303.

[0047] In a specific configuration, a second spring 3010 is fitted on the outer surface of the second vertical rod 308. The second spring 3010 can be compressed to release elastic potential energy. When the moving part 309 is not subjected to external force, the first vertical rod 304 is inserted into the through hole 303 by the second spring 3010.

[0048] In the specific setup, a handle 5 is connected to one side of the first housing 1. The handle 5 allows people to easily move the electric hoist 4 by holding it. During the transfer, the hook of the electric hoist 4 needs to be fixed inside the protective plate 201 and the fixing part 6 needs to be removed. Because the fixing part 6 is close to the human body, it needs to be removed to avoid injury to people.

[0049] In a specific configuration, multiple sets of pulleys 7 are connected to the other side of the first housing 1. The pulleys 7 facilitate the overall movement of the electric hoist 4.

[0050] The working principle of this portable traction motor lifting device is as follows: When using the portable traction motor lifting device, the output shaft of the motor 203 is controlled to rotate, which drives the bidirectional screw 204 to rotate, causing the threaded seat 205 to move. The elastic potential energy released by the compression of the first spring 207, together with the clamping plate 208, fixes the hook of the electric hoist 4 inside the protective plate 201, preventing the hook of the electric hoist 4 from shaking during the transfer. When people use the handle 5 to transfer the electric hoist 4 as a whole, by pulling the horizontal plate 307, the second vertical rod 308 is moved, which in turn moves the moving part 309, allowing the first vertical rod 304 to disengage from the through hole 303, releasing the limit on the locking part 302, allowing the locking part 302 to disengage from the slot 305, and disassembling the fixing part 6. Because the fixing part 6 is close to the person's body, it avoids the fixing part 6 from causing injury to people. This solves the problem that when people carry the electric hoist 4, the hook will keep shaking, which not only increases the physical exertion of people, but also easily causes injury.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
