Description

Technical Field

[0001] The utility model relates to a carrying device, and in particular to a lifting fixture. In addition, the utility model also relates to a lifting device and an assembly production line including the lifting fixture. Background Art

[0002] The tires used in articulated boom aerial work platform products are mainly foamed tires and solid tires, which are large in volume and heavy in weight and cannot be carried manually. Lifting equipment such as overhead cranes or combined cranes (KBK) and special lifting tools are required for lifting and assembly.

[0003] When assembling the tires, in order to maintain balance, generally a relatively wide flat sling is used to hold the tire, and it is slowly sleeved into the reducer and pushed into the stop. Due to the misalignment between the tire and the reducer hole, the tire cannot rotate during the lifting process. The tire needs to be placed on the reducer stop, and then the tire is rotated. After aligning the holes, the bolts are screwed in. Since the center of the tire is relatively high and the bottom width is small, it is easy to tilt. Therefore, during lifting, it is necessary to ensure that the sling is located at the center of the tire as much as possible, and during the lifting process, the staff needs to hold the tire by hand to prevent the tire from tipping over, which increases the working danger of the staff. In addition, the tire cannot rotate during the lifting process and needs to be pushed into the stop and in place before it can be rotated and aligned with the hole, which affects the production efficiency.

[0004] Therefore, it is necessary to design a new type of lifting fixture. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a lifting fixture that can convert the pulling force into a clamping force to lift the tire, is not prone to tilting during the lifting process, does not require manual support, enhances the safety of the staff, and during the lifting process, the tire can rotate, reducing the positioning time and improving the assembly efficiency.

The clamping mechanism includes a first clamping rod and a second clamping rod. Clamping parts are respectively formed on the opposite sides of the first clamping rod and the second clamping rod to be able to clamp the workpiece.

[0032] The following will describe in detail the specific implementation of the present utility model with reference to the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present utility model, and the protection scope of the present utility model is not limited to the following specific implementation.

[0033] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "arrangement", "provided with", "installation", "cooperation", and "connection" should be understood in a broad sense. For example, the connection can be a direct connection or an indirect connection through an intermediate medium, and can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

[0035] In the present utility model, unless otherwise stated, the orientation terms such as "away from, close to" are defined based on the inside and outside of the corresponding components. Additionally, "facing, back to" are defined based on the clamping direction of the workpiece 4, and the "axis" refers to the central axis of the workpiece 4 clamped in the present utility model. Specifically, in the drawings provided by the present utility model, the orientation or positional relationship used is based on the orientation or positional relationship shown in the drawings. What is touched is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model; for the orientation terms of the present utility model, they should be understood in combination with the actual installation state.

[0036] See Figure 1 And Figure 2 , the present utility model provides a lifting fixture, including a clamping mechanism and a rolling mechanism. Among them, the clamping mechanism includes a first clamping rod 1 and a second clamping rod 2. On the opposite sides of the first clamping rod 1 and the second clamping rod 2 and on the opposite sides of the second clamping rod 2 and the first clamping rod 1, clamping portions 3 are respectively formed to be able to clamp the workpiece 4. The rolling mechanism includes a mounting member and a rolling member 5. The rolling member 5 is rotatably mounted on the clamping portion 3 through the mounting member to be able to drive the workpiece 4 to rotate around its own axis. It can be understood that the "axis" here refers to the center line of the workpiece. During assembly, the workpiece can be rotated and adjusted based on the workpiece center to facilitate subsequent installation.

[0037] It should be noted that the main function of the clamping mechanism in the present utility model is to clamp the workpiece 4, while the main function of the rolling mechanism is to still be able to drive the workpiece 4 to rotate when the workpiece 4 is clamped, facilitating the adjustment of the position of the workpiece 4 to meet the requirements of later assembly. See Figure 3The utility model takes the tire as an example, and lifts and clamps the tire, and lifts the tire to a preset position. Since the center of the lifting point and the center of the tire are not on the same vertical plane, the tire needs to be rotated and adjusted without loosening. The utility model can rotate the tire under the drive of the rolling mechanism as needed, so that the tire is automatically leveled, reducing the time for finding the balance point and improving work efficiency. In addition, the clamping mechanism clamps the tire, which can prevent the tire from tipping over during the lifting process. No manual support is required, which saves labor costs and also improves safety.

[0038] Furthermore, the first clamping rod 1 and the second clamping rod 2 are hinged to each other through a hinge point 6, and the clamping portion 3 is respectively arranged at the lower end of the first clamping rod 1 and the second clamping rod 2. By hingedly connecting the first clamping rod 1 and the second clamping rod 2 to each other, a part of the upward pulling force is converted into a clamping force during the hoisting process. The heavier the workpiece 4, the greater the clamping force. When the hoisting fixture provided by the utility model is used for hoisting, the workpiece 4 is prevented from tipping over due to insufficient clamping force.

[0039] Specifically, a hook hole 8 is provided at one end of the first clamping rod 1 away from the clamping portion 3 and at one end of the second clamping rod 2 away from the clamping portion 3, respectively. The hook hole 8 can facilitate the connection of the lifting equipment with the lifting fixture provided by the utility model to lift the workpiece 4.

[0040] It should be noted that the hook hole 8 is only used as a specific implementation method, and the connection method with the lifting equipment is not limited to this. It can also be a hook structure hung on the lifting equipment to achieve connection.

[0041] For further information, see Figure 2 As a specific embodiment of the present invention, the mounting member includes a mounting plate 7, and the rolling member 5 is rotatably mounted on the mounting plate 7. On the one hand, the mounting plate 7 can adjust the mounting direction of the rolling member 5 so that the mounting direction of the rolling member 5 can conveniently drive the workpiece 4 to rotate. On the other hand, the mounting plate 7 can enhance the structural strength of the clamping portion 3, so that the force can be evenly applied there, thereby preventing the workpiece 4 from tilting during the clamping process, or slipping due to uneven force.

[0042] In addition, as a specific embodiment of the utility model, in order to better install and connect the mounting plate 7 with the clamping part 3, a groove structure 31 is provided on the side of the clamping part 3 facing the mounting plate 7, and the middle part of the mounting plate 7 is clamped into the groove structure 31 and fixed, so that the installation of the mounting plate 7 and the clamping part 3 is more firmly.

[0043] It should be noted that not only can the groove structure 31 be provided on the clamping part 3, but also the groove structure 31 can be provided on the mounting plate 7. The groove structures 31 of the two are clamped with each other to form a mortise and tenon structure, enhancing the overall structural strength.

[0044] Secondly, referring to Figure 1 , the cross-sections of the lower ends of the first clamping rod 1 and the second clamping rod 2 in the present utility model are both set to an "L" - shaped structure, and the inner corner of the "L" - shaped structure faces the workpiece 4. The clamping part 3 is formed at the end of the "L" - shaped structure facing the workpiece 4. With such a setting, when hoisting, when the lifting hook is pulled upwards, since the first clamping rod 1 and the second clamping rod 2 are hinged, the clamping parts 3 of the two will close towards the middle of each other, and the ends of the "L" - shaped structures of the two close to the workpiece 4 can form a clamping on the workpiece 4, increasing the clamping force and preventing loosening.

[0045] Furthermore, as a specific implementation manner of the present utility model, referring to Figure 2 , the rolling member 5 includes a bearing bolt 51, a bearing nut 52 and a roller 53. The roller 53 is sleeved on one end of the bearing bolt 51 provided with a bearing. The roller 53 is rotatably installed on the mounting plate 7 through the bearing bolt 51. The bearing bolt 51 penetrates through the mounting plate 7 and is installed on the mounting plate 7 through the bearing nut 52. Referring to Figure 3 and Figure 4 , taking the workpiece 4 hoisted by the present utility model as a tire as an example, when hoisting the tire, the rolling mechanism is lowered to the height of the tire groove. The lifting hook is pulled upwards, the roller 53 is pressed against the tire groove, and when pulled upwards continuously, the tire groove falls on the upper surface of the roller 53. The rolling device simultaneously plays a dual role of clamping and supporting the tire. With the support of the bearing, the tire can rotate easily, so as to facilitate the subsequent assembly.

[0046] Specifically, as an embodiment of the present utility model, referring to Figure 3 , two sets of rolling members 5 are provided on the mounting plate 7. The two sets of rolling members 5 are evenly arranged on the mounting plate 7. By setting two sets of rolling members 5, the contact area between the roller 53 and the workpiece 4 is increased. As shown in Figure 3 , increasing the contact area between the roller 53 and the tire makes the hoisting more stable and the rotation of the tire easier.

[0047] It should be noted that the setting of the rolling member 5 is not limited to Figure 3 . It can also be set with only one set, which can be set according to the specific use environment. And when the volume of the workpiece 4 to be hoisted is too large, the mounting plate 7 can be set to be arc - shaped, and the rolling members 5 are arranged along the arc - shaped edge of the mounting plate 7 to increase the contact area with the workpiece 4 and avoid shaking during hoisting.

[0048] The lifting fixture provided by the first aspect of the present utility model forms a clamping mechanism by arranging a first clamping rod 1 and a second clamping rod 2 to clamp a workpiece 4. Further, the first clamping rod 1 and the second clamping rod 2 are hinged to each other, and when lifting the workpiece 4, a part of the force can be converted into a clamping force. The heavier the workpiece 4 is, the greater the clamping force is. During lifting, the workpiece 4 is basically not laterally stressed, so there is no need to worry about loosening during the lifting process, reducing the probability of manual support during the transfer process and avoiding safety risks. In addition, a rolling mechanism is provided, and the workpiece 4 can be rotated during lifting. For example, when lifting a tire, before lifting, it is only necessary to ensure that the lifting fixture is located below the tire groove. When lifting, the first clamping rod 1 and the second clamping rod 2 will automatically contract and clamp towards the middle. When the lifting point center and the tire center are not in the same vertical plane, the tire will rotate and automatically level without loosening, reducing the time to find the balance point. During the lifting process, the tire is supported by the outer ring of the roller 53 and can rotate freely, and can rotate and align holes during the lifting process, reducing the positioning and rotation time and improving the operation efficiency.

[0049] It should be noted that the lifting fixture provided by the present utility model is not only applicable to lifting tires, but also can lift other workpieces, such as bearings, speed reducers, etc., and can be applied to transportation equipment, and can be set according to the actual use situation.

[0050] The second aspect of the present utility model provides a lifting device, which is configured with the lifting fixture provided in some of the above specific embodiments. When clamping the workpiece 4, it can prevent the workpiece 4 from tilting, does not require manual support, and can perform rotational positioning in the clamped state, facilitating the installation of the workpiece 4 and improving the work efficiency.

[0051] The third aspect of the present utility model provides an assembly production line. The lifting device in this production line is equipped with the lifting fixture provided by the first aspect of the present utility model. This fixture can convert the pulling force into a clamping force to lift the tire. During the lifting process, it is not easy to tilt and does not require manual support, enhancing the safety of the staff. Moreover, during the lifting process, the tire can rotate, reducing the positioning time and improving the assembly efficiency.

[0052] In the description of the present utility model, the description referring to terms such as "one embodiment", "some embodiments", "a specific implementation manner", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In the present utility model, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0053] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various simple modifications can be made to the technical solutions of the present utility model, and these simple modifications all fall within the protection scope of the present utility model.

[0054] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.
