DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, a hydraulic wheel unloading device includes a support 1, and the support 1 includes two vertical plates 2 arranged opposite to each other on the left and right, and a horizontal plate 3 is fixedly installed between the two vertical plates 2 by bolts; a placement frame 5 for placing a wheel axle 4 is provided on the top of the horizontal plate 3, and the placement frame 5 is U-shaped, and the upper ends of the two vertical walls of the placement frame 5 are respectively provided with V-shaped placement grooves 6 for stably placing the wheel axle 4, and the wheel axle 4 is horizontally placed in the two placement grooves 6, and the left and right ends of the wheel axle 4 extend out of the two sides of the placement frame 5 respectively, and the left and right ends of the wheel axle 4 are respectively provided with wheel bodies 7.

[0025] like Figure 2 and Figure 3 As shown, two abutment plates 8 are installed on the support 1 for transverse sliding, and the two abutment plates 8 are arranged opposite to each other on the left and right. Specifically, a guide rod 9 extending transversely to the left and right is fixedly installed between the two vertical plates 2 by bolts, and two guide rods 9 are arranged side by side in front and back, and the two abutment plates 8 are slidably installed on the two guide rods 9 at the same time; a notch groove 10 is provided at the upper end of the abutment plate 8 for the wheel axle 4 to pass through, and the placement frame 5 is located between the two abutment plates 8. A driving component for adjusting the distance between the two abutment plates is connected between the two abutment plates 8. Specifically, the driving component is a hydraulic cylinder 11, and the cylinder body of the hydraulic cylinder 11 is fixedly installed on the abutment plate 8 on the left by bolts, and the piston rod of the hydraulic cylinder 11 is fixedly installed on the abutment plate 8 on the right by bolts.

[0026] The support 1 is provided with a limiting mechanism for locking the position of one of the abutment plates 8, specifically, as Figure 3 As shown, the limiting mechanism includes a slide bar 12 fixedly mounted on the right abutment plate 8 by bolts, two slide bars 12 are arranged side by side in front and back, a sleeve 13 matching the slide bar 12 is fixedly mounted on the right vertical plate 2 by bolts, a second positioning hole 14 vertically penetratingly arranged is provided on the slide bar 12, a second screw hole 15 is provided on the sleeve 13, and a second positioning screw 16 matching the second positioning hole 14 is screwed into the second screw hole 15. Two push rods 17 for abutting the two ends of the wheel shaft 4 are fixedly mounted on the support 1.

[0027] During specific use, the two abutment plates 8 are first driven to approach each other through the contraction of the hydraulic cylinder 11, so that the two abutment plates 8 are respectively against the left and right sides of the placement frame 5. At the same time, the abutment plate 8 on the right side drives the sliding rod 12 to slide along the sliding sleeve 13, and the sliding rod 12 drives the second positioning hole 14 to move to align with the second screw hole 15; the wheel axle 4 is placed horizontally in the two placement grooves 6, and the wheel bodies 7 at both ends of the wheel axle 4 are respectively located on the outside of the two abutment plates 8.

[0028] When only the wheel body 7 at one end of the axle 4 needs to be disassembled, the second positioning screw 16 is screwed into the second screw hole 15 and the second screw hole 15 is passed through the second positioning hole 14, so that the right-side abutment plate 8 and the sliding rod 12 cannot move left or right; the distance between the two abutment plates 8 is enlarged by extending the hydraulic cylinder 11. Since the abutment plate 8 on the right is in a locked state, the extension of the hydraulic cylinder 11 only drives the abutment plate 8 on the left side to move leftward to enlarge the distance between the two abutment plates 8, and then the abutment plate 8 on the left side moves left to contact the wheel body 7 at the left end, driving the axle 4 and the left and right wheel bodies 7 to move left synchronously; when the axle 4 moves left and contacts the top rod 17 at the left end, the abutment plate 8 on the left side continues to move leftward, so that the wheel body 7 at the left end falls off the axle 4, completing the disassembly of the wheel body 7 at one end of the axle 4.

[0029] Or when the wheel bodies 7 at both ends of the axle 4 need to be disassembled, the second positioning screw 16 is removed from the sliding sleeve 13 to release the lock on the right abutment plate 8; the hydraulic cylinder 11 is extended to expand the distance between the two abutment plates 8, and then the left and right abutment plates 8 respectively abut against the inner sides of the left and right wheel bodies 7, and the two abutment plates 8 move away from each other so that the two wheel bodies 7 fall off from the two ends of the axle 4 respectively, thereby efficiently completing the disassembly of the wheel body 7 side at both ends of the axle 4.

[0030] Two stoppers 18 are fixedly mounted on the guide rod 9 by bolts, and the two abutment plates 8 are located between the two stoppers 18. When the wheel bodies 7 at both ends of the wheel axle 4 are disassembled, when the distance between the two abutment plates 8 is enlarged, when one of the abutment plates 8 abuts against the stopper 18 located outside thereof, the abutment plate 8 stops moving outward, and the other abutment plate 8 moves in the opposite direction, thereby efficiently disassembling the wheel bodies 7 at both ends of the wheel axle 4.

[0031] like Figure 4 As shown, a vertically extending guide column 19 is welded to the bottom of the placement frame 5, and four guide columns 19 are arranged in a rectangular array. The guide columns 19 are slidably mounted on the cross plate 3. A vertically extending adjustment screw 20 is also rotatably mounted on the bottom of the placement frame 5 through a bearing, and the adjustment screw 20 is screwed on the cross plate 3. The placement frame 5 can be raised or lowered by rotating the adjustment screw 20, and then the placement frame 5 drives the wheel axle 4 thereon to move up and down, so that the end of the wheel axle 4 is axially aligned with the top rod 17, so as to match the use of wheel axles 4 of different thicknesses.

[0032] The two vertical plates 2 are respectively provided with mounting holes 21 which are arranged horizontally through, and the two push rods 17 are respectively arranged in the corresponding mounting holes 21. The push rod 17 is provided with a first positioning hole 22 which is arranged vertically through, and a plurality of first positioning holes 22 are evenly spaced along the length direction of the push rod 17. A protruding sleeve 23 is integrally formed on the vertical plate 2 at one end of the first positioning hole 22, and the sleeve 23 is connected with the first positioning hole 22. The sleeve 23 is provided with a first screw hole 24, and a first positioning screw 25 is screwed into the first screw hole 24, and the first positioning screw 25 passes through one of the first positioning holes 22. By passing the first positioning screw 25 through different first positioning holes 22, the length of the push rod 17 extending into the inner side of the vertical plate 2 can be adjusted to facilitate the use of axles 4 of different lengths.
