Description

Technical Field

[0001] This utility model belongs to the field of axle lifting tool technology, specifically relating to a lifting tool for axle processing. Background Technology

[0002] In the automotive manufacturing and parts production sector, axles, as crucial load-bearing and transmission components, are typically large and heavy. Specialized lifting tools are required for their processing, transportation, and assembly. Currently, various types of lifting tools are available for axles, including fixed lifting rings, wire rope hooks, and U-clamps. However, existing lifting tools still have many shortcomings in practical use.

[0003] On the one hand, most existing lifting devices have relatively fixed structures and cannot be flexibly adjusted according to the axle length. Especially in production sites with diverse axle models, it is often necessary to change lifting devices of different specifications, affecting lifting efficiency. On the other hand, some structural designs cannot ensure that the axle is evenly stressed at both ends during lifting, which can easily cause the axle to tilt, or even slip or rotate, posing certain safety hazards. In addition, during the connection between the axle and the lifting device, the fixed structure often lacks convenient limit and locking mechanisms, making the installation of straps or supports cumbersome, with poor stability, and unsuitable for frequent, high-intensity lifting tasks. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lifting tool for axle processing. It can be adjusted according to the axle length, can achieve uniform force on both ends, and has a quick limiting function. This has become a technical problem that urgently needs to be solved in this field.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lifting device for axle processing, comprising a lifting frame, a lifting ring installed on the top of the lifting frame, and incomplete gears symmetrically and rotatably installed on both sides inside the lifting frame, with a swing rod provided on one side of the incomplete gear, and the two swing rods extending beyond the side of the lifting frame;

[0006] The bottom of the swing rod is rotatably mounted with a mounting base, and the top of the mounting base is symmetrically provided with upright plates. The bottom of the swing rod is rotatably mounted between the two upright plates.

[0007] A woven strap is fixed to one side of the bottom of the mounting base, and a rigid steel plate is provided at the end of the woven strap. The woven straps on both sides wrap around both ends of the axle.

[0008] Furthermore, the hanger has an inner groove vertically opened at its center, and a threaded rod is vertically rotatably installed inside the inner groove, with a knob at the bottom of the threaded rod.

[0009] Furthermore, a bidirectional toothed plate is slidably installed inside the inner groove. The bidirectional toothed plate is screwed onto the threaded rod, and the bidirectional toothed plate meshes with the two incomplete gears respectively.

[0010] Furthermore, a through groove is provided on the side of the mounting base away from the woven strap, and a fixing plate is provided on one side of the mounting base. A docking cylinder is provided on the outer side of one of the upright plates, and the through groove is placed between the fixing plate and the docking cylinder.

[0011] Furthermore, the hardened steel plate has a through groove, and positioning holes are formed on the surface of the hardened steel plate.

[0012] Furthermore, a sliding rod is horizontally penetrating the surface of the fixing plate, and a positioning bolt is provided at the end of the sliding rod. The positioning bolt passes through a positioning hole, and the end of the positioning bolt is adapted to the internal dimensions of the docking cylinder.

[0013] Furthermore, a spring is fitted onto the surface of the slide rod, with one end of the spring contacting the surface of the positioning bolt and the other end of the spring contacting the inner side of the fixing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By installing lifting rings at the top of the lifting frame to connect and cooperate with external lifting equipment, the problem of existing lifting equipment being unable to be easily connected to lifting equipment is solved, thereby enabling the rapid lifting and deployment of the entire lifting equipment and improving lifting efficiency.

[0016] By setting an internal sliding groove and threaded rod inside the hanger, and cooperating with a slidingly installed bidirectional toothed plate and a meshing incomplete gear, the two swing rods can be adjusted at the same angle, thereby driving the mounting base connected to their lower end to adjust the distance in the horizontal direction. This solves the problem that existing hangers cannot adjust the clamping position according to the axle length, enabling this device to adapt to the lifting needs of axles of different lengths and improve its versatility.

[0017] By connecting the mounting base to the lower end of the swing arm, and providing woven straps and hard steel plates at the bottom of the mounting base, the two ends of the axle can be effectively wrapped and supported, avoiding the axle tilting or rotation caused by uneven force. This solves the problem of unstable axle posture during the lifting process of existing lifting tools, and improves the stability and safety of lifting.

[0018] By setting through slots, fixing plates, connecting cylinders, sliding rods, positioning bolts, and spring structures on the mounting base, a convenient limiting and locking mechanism is formed. This mechanism enables the rapid installation and fixing of rigid steel plates without affecting the insertion operation, solving the problems of cumbersome assembly and inaccurate positioning in the connection of existing lifting tools during the support structure connection process, thereby improving the ease of operation and clamping safety.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] refer to Figures 1-5 As shown, a lifting device for axle processing includes a lifting frame 1. A lifting ring 11 is installed on the top of the lifting frame 1 and is fixed to the center of the upper end of the lifting frame 1 by welding for docking with external lifting equipment. Incomplete gears 3 are symmetrically rotated on both sides inside the lifting frame 1, and the shafts of the incomplete gears 3 are installed in the shaft holes provided on the inner walls of both sides of the lifting frame 1. A swing rod 31 is provided on one side of the incomplete gear 3 and is fixedly connected to the incomplete gear 3 by a shaft pin assembly to ensure that the two rotate synchronously. The two swing rods 31 extend beyond the side of the lifting frame 1. The swing rods 31 are made of steel round rods and have high bending strength. They are used to drive the lower mounting base 4 to swing synchronously to adjust the spacing to adapt to axle sizes of different lengths.

[0027] The bottom of the swing arm 31 is rotatably mounted with a mounting base 4. The top of the mounting base 4 is symmetrically provided with upright plates 41. The two upright plates 41 are vertically set at both ends of the upper surface of the mounting base 4 and are firmly connected to the mounting base 4 by a welding structure. The bottom of the swing arm 31 is rotatably mounted between the two upright plates 41. The rotating connection part can swing flexibly through the rotating shaft assembly, ensuring that the mounting base 4 can rotate around the axis of the swing arm 31 under the driving action to automatically adjust its posture and keep the axle in a horizontal state under force. The mounting base 4 has an overall U-shaped structure, which is used to stably support the end area of ​​the axle and provide a base for fixing with straps.

[0028] A braided strap 5 is fixed to one side of the bottom of the mounting base 4. The braided strap 5 is made of high-strength polyester fiber and is fastened to the strap fixing groove provided on the lower side of the mounting base 4 by screw fasteners. A hard steel plate 51 is provided at the end of the braided strap 5. The hard steel plate 51 is made of wear-resistant carbon steel and is used to provide a stable support surface. The braided straps 5 on both sides wrap around both ends of the axle, forming a closed lifting circuit by surrounding the axle from the top and bottom, so that the axle is subjected to stable and uniform force and prevents tilting or rotation.

[0029] refer to Figure 2 and Figure 3 As shown, an inner slide groove 12 is vertically opened at the center of the hanger 1. The inner slide groove 12 passes through the upper and lower end faces of the hanger 1 and a guide rail structure is installed inside to ensure stable guidance of the moving parts. A threaded rod 13 is vertically rotatably installed inside the inner slide groove 12. The threaded rod 13 is a through structure. The upper end is supported and connected to the bearing seat at the top of the hanger 1 through a rotating shaft, and the lower end is provided with a knob 14. The outer edge of the knob 14 is provided with anti-slip texture, which is convenient for the operator to manually rotate and adjust. Rotating the threaded rod 13 can drive the internal parts of the slide groove to rise and fall in the vertical direction, so as to realize the synchronous adjustment of the components on both sides of the hanger.

[0030] refer to Figure 3 As shown, a bidirectional toothed plate 2 is slidably installed inside the inner slide groove 12. The bidirectional toothed plate 2 has a threaded hole in the middle and is screwed onto the threaded rod 13. It moves up and down as the threaded rod 13 rotates. The two ends of the bidirectional toothed plate 2 are respectively meshed with two incomplete gears 3. When the toothed plate slides, it drives the incomplete gears 3 to rotate, thereby driving the two connected swing rods 31 to swing synchronously. The distance adjustment of the two mounting seats 4 is controlled by the gear linkage mechanism to ensure that their adjustment actions are consistent, thereby realizing the adaptive clamping of axles of different lengths.

[0031] refer to Figure 4 and Figure 5As shown, a through groove 44 is provided on the side of the mounting base 4 away from the braided strap 5. The through groove 44 is a rectangular through structure, and its two ends extend to the two sides of the mounting base 4 respectively. A fixing plate 42 is provided on one side of the mounting base 4. The fixing plate 42 is vertically connected to the mounting base 4 and the overall strength is increased by a reinforcing rib structure. A docking cylinder 43 is provided on the outer side of one of the upright plates 41. The docking cylinder 43 is installed on the outer wall of the upright plate 41 by welding. Its inner hole size is adapted to the positioning structure. The through groove 44 is placed between the fixing plate 42 and the docking cylinder 43 to form a channel space for the insertion and limiting of the rigid steel plate 51.

[0032] refer to Figure 4 and Figure 5 As shown, a rigid steel plate 51 passes through a through groove 44. The surface of the rigid steel plate 51 is provided with positioning holes 52. There are no fewer than two positioning holes 52, which are equally spaced in the middle area of ​​the length direction of the steel plate. They are used to cooperate with the limiting device for precise fixation, so as to ensure that the rigid steel plate 51 does not shift or loosen after insertion.

[0033] refer to Figure 4 As shown, a sliding rod 6 is horizontally inserted through the surface of the fixing plate 42. The sliding rod 6 is made of stainless steel and extends out of both ends of the fixing plate 42 to provide lateral sliding guidance. A positioning bolt 61 is provided at the end of the sliding rod 6. The positioning bolt 61 has a columnar structure and is installed at the end of the sliding rod 6 by means of threaded connection. The positioning bolt 61 passes through the positioning hole 52 and is inserted into the inside of the docking cylinder 43. The end of the positioning bolt 61 is adapted to the internal size of the docking cylinder 43, thereby providing a stable limiting function after the steel plate is inserted to prevent it from falling off.

[0034] refer to Figure 4 As shown, a spring 7 is fitted on the surface of the slide rod 6. The spring 7 is a helical compression spring structure. One end of the spring 7 is in contact with the surface of the positioning bolt 61, and the other end is in contact with the inner side of the fixing plate 42. The spring 7 provides axial elastic force so that the positioning bolt 61 automatically returns to the insertion state when there is no external force. During the insertion of the steel plate, the positioning bolt 61 is disengaged from the limiting hole position by manually pulling the slide rod 6. After the insertion is completed, the slide rod 6 is released, and the reset positioning operation is automatically completed by the elastic force of the spring 7, which improves the convenience and safety of use.

[0035] The working principle of this utility model is as follows: the crane and the lifting ring 11 are installed, and then the distance between the two mounting seats 4 is adjusted according to the length of the axle to be lifted. The knob 14 is rotated to control the rotation of the threaded rod 13, which in turn controls the sliding of the bidirectional toothed plate 2 inside the inner slide groove 12. The swing angle of the two swing rods 31 is controlled by the meshing of the bidirectional toothed plate 2 and the incomplete gear 3, and the angle of the swing rods 31 is kept consistent. When the axle is long, the distance between the two swing rods 31 can be increased, and vice versa, so that the mounting seat 4 can be close to both ends of the axle.

[0036] During hoisting, the mounting base 4 is vertically and horizontally positioned due to its own weight. Then, the braided straps 5 are wrapped around the axle, and the rigid steel plate 51 is inserted from bottom to top, penetrating the through slot 44. Due to the presence of the spring 7, the end of the positioning bolt 61 is placed inside the docking cylinder 43. Therefore, when installing the rigid steel plate 51, the sliding rod 6 can be pulled outward to move the end of the positioning bolt 61 outward, without obstructing the insertion of the rigid steel plate 51. After the rigid steel plate 51 is installed in place, the pressure on the positioning bolt 61 is released. At this time, the elastic force of the spring 7 can be used to make the positioning bolt 61 pass through the positioning hole 52 and cooperate with the docking cylinder 43, thereby fixing the rigid steel plate 51. At this time, the axle can be wrapped with the braided straps 5 and hoisted. This structure can adapt to the hoisting work of axles of different sizes and keep the stress points at both ends of the axle, thereby ensuring that the axle is in a horizontal state during hoisting and preventing it from tipping over.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
