Description

Technical Field

[0001] The present disclosure relates to a lifting device, in particular to a lifting device suitable for lifting vehicle parts. Background Art

[0002] In a vehicle manufacturing plant, when handling relatively large vehicle parts, multiple operators are usually required to work together. For heavier vehicle parts, auxiliary handling equipment is also needed for handling. For example, an auxiliary handling equipment is used to lift a rear axle or a front axle weighing about 50 kg from a storage position and transport it to an assembly line.

[0003] In the prior art, it is found that if the part size is large, such as long or wide, there are relatively high requirements for the working space when multiple people work together. When encountering a space where operators cannot enter, it will be difficult to handle vehicle parts. For example, on one side of the space where operators cannot enter, it is impossible to release the locking component of the auxiliary handling equipment, making it difficult to unload the vehicle parts, or it is impossible to lock the auxiliary handling equipment to the vehicle parts, resulting in a risk of damage to the vehicle parts due to dropping or collision during handling. For vehicle parts of different shapes or different models, operators also need to select different auxiliary handling equipment for handling, resulting in a need for more space beside the production line to place different auxiliary handling equipment. Changing the auxiliary handling equipment also results in low handling efficiency of vehicle parts. In some processes, it is required to adjust the direction or angular position of the vehicle parts during handling and then unload them. For example, the vehicle parts need to be flipped or rotated by 90° before unloading. In the case where the auxiliary handling equipment does not lock or cannot lock the vehicle parts, even if multiple people work together, it is still easy to cause the vehicle parts to be bumped and damaged.

[0044] First, refer to Figures 1 to 5 Describe an embodiment of the lifting device of the present disclosure.

[0045] The lifting device 1 of the present disclosure is generally used for lifting vehicle parts.

[0046] The lifting device 1 may include a control mechanism 2 and a first bracket 3 and a second bracket 4 arranged on both sides of the control mechanism. The first bracket 3 and the second bracket 4 can be respectively connected to the control mechanism 2 through a first contraction member 5 and a second contraction member 6. The control mechanism 2 can be configured to drive the corresponding first bracket 3 and second bracket 4 to move through the first contraction member 5 and the second contraction member 6.

[0047] The control mechanism 2 of the lifting device 1 of the present disclosure may include a handle member 21, a link member 22, a rotating member 23, and a motion locking member 24.

[0048] The rotating member 23 can be configured to be driven to rotate by the handle member 21. In some embodiments according to the present disclosure, the rotating member 23 can be a rotating shaft or a turntable arranged in the control mechanism 2.

[0049] The handle member 21 can be configured to allow operation of the handle member 21 on both the first bracket 3 side and the second bracket 4 side. In one embodiment according to the present disclosure, the handle member 21 can be a single handle piece fixed to the rotating member 23 in the middle (for example, a handle rod fixed to the rotating shaft in the middle). In another embodiment according to the present disclosure, the handle member 21 can include two handle rods. The first ends of the two handle rods can both be fixed to the rotating member 23 in the control mechanism 2. The second ends of the two handle rods can be respectively arranged on the first bracket 3 side and the second bracket 4 side. This enables operation of the handle member from both the first bracket side and / or the second bracket side, and the two handle rods can move synchronously and drive the rotating member to rotate. The handle member 21 can also include an extension rod 210. This enables adjustment of the length of the handle rod through the extension rod 210. In Figure 1 、 Figure 3 and Figure 4As can be seen, an extension rod is added to the handle rod on the side of the first bracket 3. This allows the operator to adjust the handle member according to the size of the actual operation space and / or the required torque. In other embodiments according to the present disclosure, the handle member 21 may include three or four handle rods to adapt to the operation requirements of the operator.

[0050] The first contraction member 5 may include a first connecting member 32 fixed to the first bracket 3. The second contraction member 6 may include a second connecting member 42 fixed to the second bracket 4.

[0051] The link member 22 may be a single-piece link fixed to the rotating member 23 in the middle (for example, a single-piece rod fixed to the rotating shaft in the center). In an embodiment according to the present disclosure, the two ends of the single-piece link may be connected to the first contraction member and the second contraction member via the first connecting member 32 and the second connecting member 42 respectively. This enables the rotational movement of the rotating member 23 to drive the single-piece link to move, and further drive the first bracket 3 and the second bracket 4 to approach or move away from each other.

[0052] The link member 22 may include multiple links. As Figure 4 shown, the link member 22 may include a first link 221 and a second link 222. The first end of the first link 221 and the first end of the second link 222 may be fixed to the rotating member 23.

[0053] In an embodiment according to the present disclosure, the second end of the first link 221 may be connected to the first contraction member 5 via the first connecting member, and the second end of the second link 222 may be connected to the second contraction member 6 via the second connecting member. This enables the rotational movement of the rotating member 23 to drive the first link 221 and the second link 222 to move, and further drive the first contraction member 5 and the second contraction member 6 to move respectively, realizing the first bracket 3 and the second bracket 4 approaching or moving away from each other.

[0054] However, the present disclosure is not limited thereto. In another embodiment according to the present disclosure, only the first end of the first link 221 or only the first end of the second link 222 may be selected to be fixed to the rotating member 23. This enables the rotational movement of the rotating member 23 to drive only the first link 221 or the second link 222 to move, so that only the first bracket 3 or only the second bracket 4 can move. This allows the operator to select the bracket movement mode of the hoisting device of the present disclosure according to actual needs.

[0055] In an embodiment according to the present disclosure, the first contraction member 5 may include a first guide rod 31 of the first bracket 3 and a first trough beam 25 of the control mechanism 2. The first guide rod 3 may move in the first trough beam 25. The second contraction member 6 may include a second guide rod 41 of the second bracket 4 and a second trough beam 26 of the control mechanism 2. The second guide rod may move in the second trough beam 26. InFigure 1 and Figure 3 In the illustrated embodiment, the first channel beam 25 and the second channel beam 26 may be an integral part. In another embodiment according to the present disclosure, the first channel beam 25 and the second channel beam 26 may be independent components of each other.

[0056] In Figures 1 to 4 the illustrated embodiment, the lifting device of the present disclosure may include a pair of first guide rods 31 and a pair of second guide rods 41. One first guide rod 31 away from the first connecting rod 221 and one second guide rod 41 away from the second connecting rod 222 may be used as movement guiding components. Figure 5 An example of assembling one first guide rod 31 and one second guide rod 41 in a channel beam is shown in a sectional view. Among them, the first guide rod 31 and the second guide rod 41 may be connected together between the ends by means such as threaded connection or pin connection.

[0057] In an embodiment according to the present disclosure, the first connecting rod 221 may drive the first bracket 3 to move under the guidance of the first guide rod 31 and the first channel beam 25 through the first connecting member 32. The second connecting rod 222 may drive the second bracket 4 to move under the guidance of the second guide rod 41 and the second channel beam 26 through the second connecting member 42.

[0058] In another embodiment according to the present disclosure, the first connecting member 32 and / or the second connecting member 42 may be of adjustable length, for example, by matching the holes on the connecting member with pins to adjust the length of the connecting member, or by matching the movable sleeve with the threaded tightening member to adjust the length of the connecting member. This enables the lifting device 1 of the present disclosure to respectively adjust the moving distances of the first bracket 3 and the second bracket 4 according to the different sizes of the vehicle parts to be lifted.

[0059] The movement locking member 24 of the control mechanism 2 may be configured to guide the movement of the handle member 21 and lock the handle member 21 in place. In Figure 1 and Figure 2 the illustrated embodiment, the movement locking member 24 may include a movement limiting member 241 provided on the side of the first bracket 3 and a locking member 242 arranged on the side of the second bracket 4. The movement limiting member 241 may define the movement range of the handle member 21. The locking member 242 may define the movement range of the handle member 21 and may lock the handle member 21.

[0060] In some embodiments according to the present disclosure, the locking member 242 may be a locking portion in a form well known to those skilled in the art, such as a card slot, a pin or a buckle. In Figure 2In the illustrated embodiment, the locking member 242 may include a card slot. The handle member 21 is in a state of being locked in the card slot by the locking member 242 on the side of the second bracket 4. An operator can unlock the handle member 21 from the card slot of the locking member 242 on the side of the first bracket 3 or on the side of the second bracket 4, and can move the handle member 21 along the locking member 242 in the direction shown by the arrow F2 on the side of the second bracket 4 and move the handle member 21 along the movement limiting member 241 in the direction shown by the arrow F1 on the side of the first bracket 3.

[0061] Each of the first bracket 3 and the second bracket 4 of the hoisting device 1 of the present disclosure may have at least one cross beam and a vertical bearing portion extending downward from the at least one cross beam. In Figure 1 and Figure 4 In the illustrated embodiment, the first retractable member 5 and the second retractable member 6 may be respectively fixed to at least one cross beam on the upper part of the first bracket 3 and the second bracket 4.

[0062] In an embodiment according to the present disclosure, a protective pad 7 may be arranged on the at least one cross beam and the vertical bearing portion. This can avoid the collision and wear between the vehicle parts and the hoisting device.

[0063] The vertical bearing portion may include at least two load-bearing vertical beams and a load-bearing plate arranged at the end of the load-bearing vertical beams. The load-bearing plate can be used to contact the vehicle parts, and the load-bearing plate extends under the vehicle parts, for example, to lift the vehicle parts. Each load-bearing vertical beam may include at least one support block 8. The support block 8 may be arranged at the upper end, lower end or middle of the load-bearing vertical beam, or may be arranged on the load-bearing plate. In Figure 1 In the illustrated embodiment, the hoisting device 1 includes four support blocks 8 arranged on the load-bearing vertical beams. The support block 8 may be made of wear-resistant industrial plastic, so that the support block 8 can at least prevent the wear between the vehicle parts and the vertical bearing portion.

[0064] In an embodiment according to the present disclosure, the support block 8 may also be configured to match a partial shape of the vehicle part to be contacted. This enables the vehicle parts to be better positioned and fixed in the first bracket 3 and the second bracket 4. In another embodiment according to the present disclosure, at least two types of support blocks may be installed simultaneously in the hoisting device of the present disclosure, respectively matching at least two types of vehicle parts. This enables the same hoisting device of the present disclosure to be suitable for hoisting at least two types of vehicle parts. This enables the operator not to need to replace different hoisting devices for different vehicle parts.

[0065] In an embodiment according to the present disclosure, the support block may be replaceable. This enables the hoisting device 1 to replace and use support blocks with different shape matches according to different vehicle parts to be hoisted.

[0066] The vertical load-bearing part may include a reinforcing member. In one embodiment according to the present disclosure, the vertical load-bearing part may include a reinforcing beam disposed between the supporting vertical beams.

[0067] The vertical load-bearing parts of the first bracket 3 and the second bracket 4 may have different shapes and / or heights and / or widths. This enables the lifting device of the present disclosure to adapt to vehicle parts of different configurations.

[0068] The lifting device 1 of the present disclosure may also be equipped with a handle. The handle can facilitate the operator to grip the lifting device 1 and prevent the operator from accidentally touching the handle member 21 and causing the vehicle part to fall. In Figure 1 , Figure 3 and Figure 4 In the illustrated embodiment, the handle may be assembled on the side of the first bracket 3. In other embodiments, the handle may be assembled on the side of the second bracket or on the control mechanism.

[0069] The control mechanism 2 of the lifting device 1 of the present disclosure may further include a lifting ring 27 for connecting to a hoisting machine. In Figures 1 to 5 In the illustrated embodiment, the lifting ring may be disposed in the middle of the upper part of the control mechanism 2.

[0070] The lifting device 1 of the present disclosure can adjust the center of gravity. This allows the lifting device 1 to adjust the center of gravity position of the lifting device 1 according to the center of gravity of the vehicle part to be lifted.

[0071] In some embodiments according to the present disclosure, a counterweight may be disposed in the first bracket 3 and / or the second bracket 4. In Figure 1 and Figure 4 In the illustrated embodiment, the counterweight may be disposed on the outer side of the cross beam of the second bracket 4.

[0072] In some embodiments according to the present disclosure, the center of gravity position of the lifting device 1 can be adjusted by changing the positioning of the lifting ring 27. In Figure 1 In the illustrated embodiment, the support structure of the lifting ring can move horizontally and longitudinally in the control mechanism 2 to adjust the position of the lifting ring in the control mechanism 2.

[0073] Refer to Figures 6 to 9 to describe an embodiment of the cooperation between the lifting device of the present disclosure and a vehicle part. When loading a vehicle part onto the lifting device 1 of the present disclosure, first place the first bracket 3 and the second bracket 4 on both sides of the vehicle part to be carried. The operator can manipulate the handle member 21 on the side of the first bracket 3 or the second bracket 4 to move the handle member 21 along the movement limiting member 241 from the initial position (for example, in Figure 4On the first bracket side, move the handle member 21 downward from top to bottom in the direction opposite to F1, driving the rotation member 23 and the link member 22 to move. Then, through the first contraction member 5 and the second contraction member 6, the first bracket 3 and the second bracket 4 move closer to each other until the handle member 21 on the second bracket 4 side falls into the locking member 242 and is locked and cannot move. At this time, the first bracket 3 and the second bracket 4 stop moving relative to each other, and the vehicle part is clamped between the first bracket 3 and the second bracket 4. At this time, the operator can use the hoisting machinery to guide the lifting equipment to carry the vehicle part to the target position (for example, carry it to the vehicle assembly line). During unloading, the operator releases the handle member 21 from the locking member 242 on the first bracket 3 side or the second bracket 4 side, and moves the handle member 21 along the movement limiting member 241 to the initial position (for example, in Figure 4 on the first bracket side, move the handle member upward from bottom to top in the direction of F1), driving the rotation member 23 and the link member 22 to move. Then, through the first contraction member 5 and the second contraction member 6, the first bracket 3 and the second bracket 4 move away from each other until the handle member 21 returns to the initial position, and the vehicle part between the first bracket 3 and the second bracket 4 is released. When it is necessary to change the orientation of the vehicle part to be lifted (for example, the vehicle part needs to be rotated 90° first and then unloaded), since the lifting equipment 1 of the present disclosure can keep clamping the vehicle part, an operator can rotate the vehicle part by means of the lifting equipment 1 of the present disclosure.

[0074] Although the present disclosure has been disclosed above with preferred embodiments, it is not used to limit the present disclosure. Any person skilled in the art can make possible changes and modifications to the technical solution of the present disclosure by using the methods and technical contents disclosed above without departing from the spirit and scope of the present disclosure. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present disclosure without departing from the technical solution of the present disclosure shall fall within the protection scope of the technical solution of the present disclosure.
