[0002] Axle pins are a type of standardized fasteners, mainly used at the hinge of two parts to form a hinge connection, which is reliable and easy to disassemble. The material selection of axle pins is also very particular. Commonly used materials include 45 steel, 40Cr, etc. After quenching and tempering, these materials can obtain higher strength and toughness and adapt to various complex working conditions. The existing axle pin installation method is to use a heavy hammer plus a sleeper or a striker plus a sleeper to knock the suspension shaft to make the pin pass through the pin hole.

[0003] After searching, a Chinese patent with announcement number CN218613829U discloses an installation device for a crane pin shaft, including a U-shaped fixing frame and a side thrust mechanism arranged in the U-shaped fixing frame. The utility model can realize the rapid installation and jacking of the crane shaft, reduce the crane lifting and personnel installation costs, and obtain a low-cost, high-efficiency, and easy-to-implement crane shaft rapid installation and jacking operation device.

[0004] When the above-mentioned axle pin installation device is in use, it is aligned with the axle pin hole on the boom wall panel, and then the axle pin is gradually pushed into the axle pin hole on the boom wall panel with a jack. However, it is inconvenient to rotate the axle pin, which will cause the gap between the axle pin and the axle pin hole to be too large, and a close fit cannot be achieved, thereby affecting the stability of the connection.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to the attached drawings of the specification Figure 1-6 , the installation device of the shaft pin of this embodiment includes a fixing frame 1. An installation frame 4 is movably arranged inside the fixing frame 1. A connecting component 2 is arranged on one side of the installation frame 4. The connecting component 2 includes a U-shaped plate 201 and an indicating plate 202, and the indicating plate 202 is fixedly installed at the top of the U-shaped plate 201. A rotating component 3 is arranged between the U-shaped plate 201 and the installation frame 4. The rotating component 3 includes a connecting frame 301, a first motor 302 and a rotating shaft 303. One side of the connecting frame 301 is fixedly connected to the installation frame 4. The two ends of the rotating shaft 303 are respectively fixedly connected to the connecting frame 301 and the end of the output shaft of the first motor 302. The first motor 302 is fixedly installed on one side of the U-shaped plate 201. A moving component 5 is arranged on the U-shaped plate 201. The moving component 5 includes a second motor 501, a lead screw 502, a slide bar 503 and two sliders 504.

[0029] Furthermore, the second motor 501 is fixedly installed on one side inside the fixing frame 1, and the end of the output shaft of the second motor 501 is fixedly connected to the lead screw 502. Both ends of the slide bar 503 are fixedly connected to the fixing frame 1. The two sliders 504 are respectively movably sleeved on the lead screw 502 and the slide bar 503, and the opposite sides of the two sliders 504 are both fixedly connected to the U-shaped plate 201. Two partition plates 9 are fixedly connected inside the fixing frame 1, and the two partition plates 9 are respectively movably sleeved on the lead screw 502 and the slide bar 503. Scales 6 are movably arranged on the front and back sides of the indicating plate 202, and the bottoms of the two scales 6 are both fixedly connected to the fixing frame 1.

[0030] Furthermore, an extrusion component 8 is arranged on the installation frame 4. The extrusion component 8 includes a third motor 801, a gear rod 802, two toothed plates 803, two side plates 804, two extrusion plates 805 and two limiting rods 806. The third motor 801 is fixedly installed on one side inside the installation frame 4, and the end of the output shaft of the third motor 801 is fixedly connected to the gear rod 802. The two toothed plates 803 are both meshed with the gear rod 802, and the opposite sides of the two toothed plates 803 are respectively fixedly connected to the two side plates 804. One side of the two extrusion plates 805 passes through the installation frame 4 and is respectively fixedly connected to the two side plates 804. One ends of the two limiting rods 806 respectively penetrate through the two toothed plates 803 and are fixedly connected to the installation frame 4.

[0031] Among them, the axle pin is placed on one side of the mounting bracket 4, and the axle pin is located between two pressing plates 805. The third motor 801 is started, and the third motor 801 drives the gear rod 802 to rotate. Since the gear rod 802 meshes with two toothed plates 803, and two limiting rods 806 and two side plates 804 cooperate to limit the rotation of the two toothed plates 803, the gear rod 802 can drive the two toothed plates 803 to move towards each other, thereby driving the two side plates 804 to move towards each other, and further driving the two pressing plates 805 to move towards each other, and the axle pin is fixed by pressing through the two pressing plates 805.

[0032] Furthermore, a handle 7 is fixedly connected to the center position of the side of the fixing frame 1 away from the mounting bracket 4 to facilitate lifting the fixing frame 1.

[0033] The usage method of this embodiment is as follows:

[0034] When in use, the second motor 501 is started, and the second motor 501 drives the lead screw 502 to rotate. Since one of the sliders 504 is threadedly connected to the lead screw 502, and the other slider 504 and the slide rod 503 cooperate to limit the rotation of the U-shaped plate 201, the lead screw 502 can drive the U-shaped plate 201 to move horizontally, thereby driving the rotating assembly 3 to move horizontally, and further driving the axle pin to move horizontally, and enabling the axle pin to be inserted into the axle pin hole. The first motor 302 is started, and the first motor 302 drives the rotating shaft 303 to rotate, thereby driving the connecting frame 301 and the mounting bracket 4 to rotate, and further driving the axle pin to rotate. The operation is simple, which is convenient for rotating the axle pin, effectively improving the connection stability. At the same time, the partition plate 9 can limit the slider 504 to prevent the slider 504 from pressing the second motor 501. The horizontal movement of the U-shaped plate 201 can drive the indicator plate 202 to move horizontally, and the moving distance of the axle pin can be observed through the indicator plate 202 and the two scales 6.

[0035] It should be noted that the first motor 302, the second motor 501, and the third motor 801 are all internally provided with electromagnetic locking structures.
