Description

Technical Field

[0001] This utility model relates to the field of hoisting and transportation technology, and in particular to a handling device. Background Technology

[0002] Large assembly equipment is required during the assembly of mobile phone cameras. However, larger components such as CNC four-axis machines and modules require regular maintenance and debugging. They need to be moved during disassembly, repair, and installation. These components are heavy, but in the complex working environment of a production workshop, it is not advisable to use large handling machinery. Instead, multiple people work together to move them. However, manual handling is prone to safety accidents, and multiple people working together can lead to low production efficiency in the workshop. Utility Model Content

[0003] This utility model provides a handling device that can be used in complex working environments such as production workshops. Only one person is needed to use it to handle some heavy parts, which reduces the risk of safety accidents and allows more workers to engage in other production and manufacturing activities, thereby improving the efficiency of the production workshop.

[0004] This application provides a conveying device, including a frame, a wheel assembly, a power assembly, and a lifting assembly;

[0005] The wheel assembly is located at the bottom of the frame;

[0006] The power assembly is mounted on the frame;

[0007] The lifting assembly includes:

[0008] A worm gear is mounted on the frame and is connected to the power assembly for transmission; the worm gear can be driven to rotate by the power assembly.

[0009] One end of the turbine lifting shaft is meshed with the worm gear;

[0010] A traction rope, one end of which is connected to the frame, and the other end which is wrapped around the other end of the turbine lifting shaft; and

[0011] The movable pulley lifting hook is connected to the traction rope.

[0012] In some embodiments, the turbine lifting shaft has an integrally formed turbine engagement portion and a rope wrapping portion, the turbine engagement portion being engaged with the worm gear, and the rope wrapping portion being used to wrap a traction rope;

[0013] Alternatively, the turbine lifting shaft includes a turbine and a lifting shaft, the turbine being sleeved on the outer periphery of the lifting shaft, the lifting shaft being rotatably mounted on the frame, the turbine being meshed with the worm gear, and the lifting shaft being used to wind the traction rope.

[0014] In some embodiments, the power assembly includes a drive element, a drive wheel, and a timing belt;

[0015] The timing belt wraps around the outer periphery of both the drive wheel and the worm gear;

[0016] The power end of the drive component is connected to the drive wheel. The drive component can drive the drive wheel to rotate, which in turn drives the worm gear to rotate, thereby driving the turbine lifting shaft to rotate. This causes the turbine lifting shaft to release or retract the traction rope, thus lifting the movable pulley hook.

[0017] In some embodiments, a driven wheel is sleeved on the outer periphery of the worm gear, the driven wheel is connected to the timing belt, and the radius of the driven wheel is less than or equal to the radius of the drive wheel.

[0018] In some embodiments, the driving element includes a crank or a drive motor; wherein, when the driving element is the crank, the distance between the handle portion of the crank and the center of its rotation is three times or more the radius of the drive wheel.

[0019] In some embodiments, the rack has a bottom frame, a middle frame, and a top frame, the bottom frame being connected to the bottom of the middle frame, and the top frame being connected to the top of the middle frame;

[0020] The bottom frame and the top frame define a lifting space for the object being lifted, and the side of the bottom frame away from the middle frame has reserved clearance space for the object being lifted to enter the bottom frame.

[0021] The wheel assembly is disposed at the bottom of the bottom frame;

[0022] The lifting assembly is mounted on the top frame;

[0023] The main body of the power assembly is located in the middle of the intermediate frame, and the power end of the power assembly is connected to the worm gear transmission located on the top frame.

[0024] In some embodiments, at least one location at both ends and the middle of the turbine lifting shaft is simultaneously connected to the top frame via a transmission connection.

[0025] In some embodiments, a handle is provided in the middle of the intermediate frame and on the side opposite to the power assembly.

[0026] In some embodiments, the wheel assembly includes at least two swivel wheels and at least two directional wheels, the swivel wheels being disposed on the bottom frame near the middle frame, and the directional wheels being disposed on the bottom frame away from the middle frame.

[0027] In some embodiments, the omnidirectional wheels and the directional wheels are located on opposite sides of the intermediate frame.

[0028] As can be seen from the above technical solutions, this utility model has the following advantages:

[0029] The wheel assembly is located at the bottom of the frame, allowing workers to move the frame by pushing it. The power assembly is mounted on the frame, and the worm gear of the lifting assembly is mounted on the frame and connected to the power assembly, enabling the worm gear to rotate. One end of the turbine lifting shaft is engaged with the worm gear, one end of the traction rope is connected to the frame, and the other end is wrapped around the other end of the turbine lifting shaft. The movable pulley lifting hook is connected to the traction rope, allowing workers to directly hook the heavy objects to be moved, such as CNC four-axis components or modules, or use tools such as ropes to connect the movable pulley lifting hook to the heavy objects. Next, the worker can activate the power unit to wind the traction rope around the turbine lifting shaft, causing the movable pulley lifting hook to move upward and lift the heavy object off the ground. Then, the worker pushes the frame to move the heavy object to the target position and activates the power unit again to release the traction rope from the turbine lifting shaft, causing the movable pulley lifting hook to move downward and lower the heavy object. Thus, the handling device of this utility model can be used in complex working environments such as production workshops. Only one person is needed to use it to handle some heavy parts, which is less likely to cause safety accidents and allows more workers to devote themselves to other production processes, thereby improving the efficiency of the production workshop.

[0041] like Figures 1-5As shown in the illustration, this application proposes a handling device, including a frame 1, a wheel assembly 2, a power assembly 3, and a lifting assembly 4. The wheel assembly 2 is disposed at the bottom of the frame 1, and the power assembly 3 is disposed on the frame 1. The lifting assembly 4 includes a worm gear 41, a turbine lifting shaft 42, a traction rope 43, and a movable pulley lifting hook 44. The worm gear 41 is disposed on the frame 1 and is connected to the power assembly 3 for transmission. The worm gear 41 can be driven to rotate by the power assembly 3. One end of the turbine lifting shaft 42 is engaged with the worm gear 41. One end of the traction rope 43 is connected to the frame 1, and the other end of the traction rope 43 is wrapped around the other end of the turbine lifting shaft 42. The movable pulley lifting hook 44 is connected to the traction rope 43. The movable pulley lifting hook 44 can directly hook the heavy object to be moved, or it can be connected to the heavy object with the help of tools such as ropes.

[0042] The process of using the handling device of this application to handle some relatively heavy parts is as follows:

[0043] The worker connects the movable pulley lifting hook 44 to the accessory; then, the power unit 3 is activated to drive the worm gear 41 to rotate, which in turn drives the turbine lifting shaft 42 to rotate, allowing the turbine lifting shaft 42 to wind the traction rope 43, so that the movable pulley lifting hook 44 moves upward and lifts the accessory off the ground; since the accessory is heavy, it is advisable to use the wheel assembly 2 at the bottom of the frame 1 to push the frame 1 to move it after the accessory has stabilized, thus transferring the accessory; after the accessory is transferred to the target position, the worker can activate the power unit 3 again to drive the worm gear 41 to rotate in the opposite direction, so that the turbine lifting shaft 42 releases the traction rope 43, causing the movable pulley lifting hook 44 to move downward and lower the accessory.

[0044] The handling device of this utility model can be used in complex working environments such as production workshops. Only one person is needed to use it to handle some heavy parts, allowing more workers to devote themselves to other production and manufacturing processes, thereby improving the efficiency of the production workshop. During the process of lifting or lowering the parts, the worm gear 41 and the turbine lifting shaft 42 can form a self-locking mechanism, which can prevent the parts from falling suddenly. In addition, when the worker pushes the frame 1 to move it, the worker will not directly contact the parts, but will perform the action on the side of the frame 1 away from the parts. This can effectively avoid the parts from causing injury to the worker when handling the parts. Therefore, it is not easy to have a safety accident when using the handling device of this utility model.

[0045] It should be noted that the worm gear 41 and the turbine lifting shaft 42 can form a self-locking mechanism. Starting from the automatic power assembly 3, power is transmitted from the worm gear 41 to the turbine lifting shaft 42, and then successively to the traction rope 43, the movable pulley lifting hook 44, and finally to the accessory, causing the accessory to move up / down. However, power is not transmitted from the turbine lifting shaft 42 to the worm gear 41. In this way, the accessory will not suddenly fall off the frame 1 when it is lifted off the ground. Furthermore, there is a very high transmission ratio between the worm gear 41 and the turbine lifting shaft 42. When the worker starts the power assembly 3 to drive the worm gear 41 to rotate, only a small torque is needed to drive the turbine lifting shaft 42 to rotate, winding or releasing the traction rope 43, thus enabling the heavy accessory to move up / down. Therefore, the load on the power assembly 3 is not too large. It can drive the worm gear 41 to rotate smoothly and is not easy to break. It can be used for a long time in the production workshop for the handling of accessories.

[0046] In addition, the handling device of this application uses a movable pulley lifting hook 44, and the transmission ratio between the end of the traction rope 43 wound around the turbine lifting shaft 42 and the accessory is 2:1. This can reduce the force of the turbine lifting shaft 42 driving the accessory to move up / down, and can reduce the load on the power component 3 to a certain extent.

[0047] Bearings are provided at both ends and at least one location in the middle of the turbine lifting shaft 42. The turbine lifting shaft 42 is rotatably mounted on the frame 1 via the bearings. The tensile force of the accessories on the turbine lifting shaft 42 can be distributed at multiple locations where it is connected to the frame 1, and the turbine lifting shaft 42 is not easily pulled and deformed by the accessories.

[0048] In some embodiments, the turbine lifting shaft 42 is an integrally formed structure, the turbine lifting shaft 42 has a turbine engagement part 421 and a rope winding part 422, the turbine engagement part 421 has a toothed ring that can engage with the worm gear 41, and the rope winding part 422 is used to wind the traction rope 43.

[0049] In other embodiments, the turbine lifting shaft 42 is formed by assembly. The turbine lifting shaft 42 includes a turbine and a lifting shaft. The turbine is sleeved on the outer periphery of the lifting shaft and fixed to the lifting shaft. The lifting shaft is rotatably mounted on the frame 1. The turbine and the worm gear 41 are meshed and connected. The lifting shaft is used to wind the traction rope 43.

[0050] The handling device of this application is used to handle large-volume components such as CNC four-axis components and modules. Some components require the use of tools such as ropes and movable pulleys to connect to the lifting hook 44, and the lifting and lowering of the components is achieved by using the winding and releasing of the traction rope 43. As a result, the distance between the bottom of the component and the turbine lifting shaft 42 is relatively long. In order to facilitate workers' observation and operation, the turbine lifting shaft 42 needs to be set at a relatively high position.

[0051] In some embodiments, the power assembly 3 includes a drive member 31, a drive wheel 32, and a timing belt 33. The timing belt 33 is wrapped around the outer periphery of both the drive wheel 32 and the worm gear 41. The power end of the drive member 31 is connected to the drive wheel 32. The drive member 31 can drive the drive wheel 32 to rotate, thereby rotating the timing belt 33 and the worm gear 41, which in turn drives the turbine lifting shaft 42 to rotate. This causes the turbine lifting shaft 42 to release or retract the traction rope 43, thereby lifting the movable pulley lifting hook 44 and ultimately lifting the accessories.

[0052] By setting the synchronous belt 33, the drive unit 31 can be positioned in a location convenient for workers to operate, and the worm gear 41 and the turbine lifting shaft 42 can be positioned at a relatively high position. Here, a position convenient for workers to operate means a position 1.3 meters to 1.5 meters above the ground. With the turbine lifting shaft 42 positioned at a relatively high position, the height of the frame 1 is correspondingly higher. The portion of the traction rope 43 between the movable pulley lifting hook 44 and the top of the frame 1 can be appropriately extended. This can prevent the frame 1 from being too low, so that the worker's view of the lifting and lowering of the parts is not obstructed by the top of the frame 1.

[0053] A toothed ring can be provided on the outer periphery of the worm 41 so that it can mesh with the timing belt 33 for transmission.

[0054] A driven wheel 34 can also be fitted around the outer periphery of the worm 41. The driven wheel 34 and the worm 41 are fixed by a spline. The driven wheel 34 is connected to the timing belt 33. The driving component 31 can drive the driving wheel 32 to rotate, so as to simultaneously drive the timing belt 33, the driven wheel 34 and the worm 41 to rotate.

[0055] Preferably, the radius of the driven wheel 34 is less than or equal to the radius of the drive wheel 32, and the linear velocities of the driven wheel 34 and the drive wheel 32 are the same. When the radius of the driven wheel 34 is less than the radius of the drive wheel 32, the driven wheel 34 rotates faster than the drive wheel 32. Correspondingly, the worm gear 41 rotates faster than the drive wheel 32. Under the premise of ensuring that the load on the drive component 31 is not too large, the worm lifting shaft 42 rotates faster, so that the lifting and lowering speed of the parts is faster, thereby shortening the handling time of the parts and improving the handling efficiency.

[0056] In some embodiments, the drive member 31 includes a crank 35 or a drive motor. When the drive member 31 is a crank 35, the distance between the handle portion of the crank 35 and the center of its rotation is three times or more the radius of the drive wheel 32. This arrangement makes it easier for workers to manually crank the crank 35.

[0057] The worker manually cranks handle 35, and power is transmitted from handle 35 through drive wheel 32, synchronous belt 33, driven wheel 34, worm gear 41, turbine lifting shaft 42, traction rope 43, and movable pulley lifting hook 44 to the accessories. In actual operation, the distance between the handle part of handle 35 and its center of rotation can be taken as 3 times the radius of drive wheel 32, the transmission ratio between drive wheel 32 and driven wheel 34 is 1:3, the transmission ratio between worm gear 41 and turbine lifting shaft 42 is 40:1, the ratio of the radius of the turbine part of turbine lifting shaft 42 to the part wound with traction rope 43 is 3:1, and the transmission ratio between the part of turbine lifting shaft 42 wound with traction rope 43 and the accessories is 2:1. This allows the worker to easily crank handle 35 to smoothly lift and lower heavy objects such as accessories. Generally, one rotation of handle 35 will raise or lower the heavy object by 5mm.

[0058] The frame 1 has a bottom frame 11, a middle frame 12 and a top frame 13. The bottom frame 11 is connected to the bottom of the middle frame 12 and the top frame 13 is connected to the top of the middle frame 12. Most of the bottom frame 11 and the top frame 13 are located on the same side of the middle frame 12, so that a lifting space 14 for the object to be lifted is defined between the bottom frame 11 and the top frame 13, and a clearance space 15 is reserved on the side of the bottom frame 11 away from the middle frame 12 for the object to be lifted to enter the bottom frame 11.

[0059] The wheel assembly 2 is located at the bottom of the bottom frame 11, and the lifting assembly 4 is located on the top frame 13. The two ends and at least one position in the middle of the turbine lifting shaft 42 are simultaneously connected to the top frame 13 for transmission. The main body of the power assembly 3 is located in the middle of the intermediate frame 12. The power end of the power assembly 3 is connected to the worm gear 41 located on the top frame 13 for transmission. This can be understood as follows: when driven by the crank 35 or the motor, the power drives the worm gear 41 to rotate through the drive wheel 32, the synchronous belt 33, and the driven wheel 34. The driven wheel 34 is equivalent to the power end of the power assembly 3. The driven wheel 34 and the worm gear 41 are coaxially arranged. The worm gear 41 is located on the top frame 13, that is, the power end of the power assembly 3 is connected to the worm gear 41 located on the top frame 13 for transmission. The main body of the power assembly 3 is located in the middle of the intermediate frame 12 to facilitate the operation of the power assembly 3 by the workers.

[0060] Whether it is the bottom frame 11, the middle frame 12, or the top frame 13, they are all assembled from multiple rod-shaped components. The rod-shaped components can be fixed by welding or bolt connection. Using multiple rod-shaped components for assembly can effectively reduce the weight of the frame 1 and ensure the structural strength of the frame 1.

[0061] A handle 16 is provided in the middle of the intermediate frame 12 and on the side away from the main body of the power assembly 3. The worker can hold the handle 16 to push the intermediate frame 12 and move the transport device by means of the wheel assembly 2 under the bottom frame 11.

[0062] The wheel assembly 2 includes at least two swivel wheels 21 and at least two directional wheels 22. The swivel wheels 21 are located on the bottom frame 11 near the middle frame 12, and the directional wheels 22 are located on the bottom frame 11 away from the middle frame 12. The swivel wheels 21 are located relatively close to the worker, allowing the worker to easily adjust and steer the handling device when carrying heavy objects. Preferably, the swivel wheels 21 and directional wheels 22 are located on opposite sides of the middle frame 12, which can effectively prevent the middle frame 12 from tipping over.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
