By the fixing part 210 and the clamping part 220 respectively abutting against the drawbar seat 40 and driving the two glands 420 of the drawbar seat 40 to move towards each other, the distance between the two glands 420 decreases, and the drawbar rubber pad 430 is squeezed and deformed, providing a basis for disassembling and assembling the drawbar seat 40, effectively solving the problem that the elasticity of the drawbar rubber pad 430 makes it difficult to disassemble and assemble the drawbar seat 40, improving the operation quality and efficiency, and saving time and labor; when the gland 420 moves to a preset distance from the vertical plate 4102 of the drawbar seat body 410, tighten the nut 440 to complete the assembly of the drawbar seat 40; when there is a gap between the gland 420 and the nut 440 of the drawbar seat 40, at this time, the nut 440 can be easily loosened, avoiding the nut 440 being unable to loosen due to force, and then removing the drawbar fork head 460, the gland 420, and the drawbar rubber pad 430 to complete the disassembly of the drawbar seat 40.

Among them, the first gland cover 420 is far from the fork head 470, and the second gland cover 420 is close to the fork head 470; the preset clamping position is that both the first gland cover 420 and the second gland cover 420 are located between the fixing part 210 and the clamping part 220, the fixing part 210 is located on the side of the first gland cover 420 far from the second gland cover 420, and the clamping part 220 is located on the side of the second gland cover 420 far from the first gland cover 420.

[0060] It should also be noted that the driving member 30 is a hydraulic cylinder, and its specific structure and working principle are both prior arts, and will not be elaborated in this application.

[0061] It should also be noted that a plurality of universal wheels are provided at the bottom of the trolley 10, and a push handle is provided on one side of the trolley 10.

[0062] It should also be noted that a hydraulic station is further provided on the trolley 10 to provide hydraulic pressure for the driving member 30, the first push cylinder 2201 and the second push cylinder 2203; the hydraulic station is also called a hydraulic pump station, which is an independent hydraulic device. It supplies oil according to the step-by-step requirements, and controls the direction, pressure and flow of the hydraulic oil, and is applicable to various hydraulic machines where the main engine and the hydraulic device can be separated; connecting the hydraulic station and the actuator (cylinder or oil motor) on the main engine with oil pipes, the hydraulic machine can realize various specified actions and working cycles. The specific structure and working principle of the hydraulic station are both prior arts, and will not be elaborated in this application.

[0063] It should also be noted that the preset spacing is 8 - 12 mm; there is an angle between the drawbar 450, the draw fork head 460, the two gland covers 420 and the horizontal plane. For example, the angle is 6°. In addition, as Figure 1 shown, the horizontal plane is parallel to the XOY plane.

[0064] As Figure 1 、 Figure 2 shown, in some embodiments, the fixture 20 further includes a support frame 230 and a plurality of limiting rods 240; a first opening 2301 and a second opening are respectively provided on both sides of the support frame 230. The first opening 2301 is for the nut 440 of the draw seat 40 to pass through, and the second opening is for the fork head 470 of the draw seat 40 to pass through; the plurality of limiting rods 240 are arranged on the support frame 230, and the plurality of limiting rods 240 are used to abut against the draw seat body 410 of the draw seat 40; wherein, the fixing part 210 is arranged at the first opening 2301, and the clamping part 220 is arranged at the second opening.

[0065] By providing the support frame 230, a structural basis is provided for installing the fixing part 210 and the clamping part 220; by the abutment of the plurality of limiting rods 240 against the draw seat body 410, a limiting effect is achieved, and at this time the driving part 30 stops moving; by providing the first opening 2301, a space is reserved for the nut 440 to avoid interference between the nut 440 and the support frame 230, and by using the second opening, a space is reserved for the clamping part 220 to avoid interference between the fork head 470 and the support frame 230.

[0066] It should be noted that the plurality of limiting rods 240 are located on the side of the support frame 230 away from the trolley 10.

[0067] As Figure 1 shown, in some embodiments, the fixing part 210 includes first pressing members 2101 respectively arranged on both sides of the first opening 2301, and the first pressing members 2101 are used to abut against the gland cover 420 away from the fork head 470.

[0068] As Figure 1 、 Figure 2 shown, in some embodiments, the clamping part 220 includes two first pushing cylinders 2201 and two first pushing members; the two first pushing cylinders 2201 are respectively located on both sides of the second opening; the two first pushing members respectively correspond to the two first pushing cylinders 2201, and the first pushing members are arranged on the telescopic rods of the corresponding first pushing cylinders 2201, and the first pushing members are used to abut against the gland cover 420 close to the fork head 470.

[0069] The first pressure stop member 2101 is in contact with the pressure cover 420 away from the fork head 470, and the telescopic rod of the first pushing cylinder 2201 drives the first pushing member to move. The first pushing member applies pressure to the pressure cover 420 to compress the pressure cover 420, thereby compressing the traction rubber pad 430 in the pressure cover 420, and the two pressure covers 420 move toward each other, thereby facilitating the disassembly and assembly of the traction seat 40 and improving the disassembly and assembly efficiency of the entire traction seat 40.

[0070] like Figure 1 As shown, in some embodiments, the support frame 230 is rotatably disposed on one side of the cart 10 , the driving member 30 is rotatably disposed on the cart 10 , and the telescopic rod of the driving member 30 is hinged to the support frame 230 .

[0071] The support frame 230 is driven to rotate by the telescopic rod of the driving member 30. When the disassembly and assembly device is not in use, the driving member 30 drives the support frame 230 to rotate above the cart 10, thereby saving working space and facilitating storage; when the disassembly and assembly device is in use, the driving member 30 drives the support frame 230 to rotate, so that the support frame 230 is sleeved on the traction seat 40, so that the clamp 20 reaches the preset clamping position, preparing for the disassembly and assembly of the traction seat 40.

[0072] It should be noted that the support frame 230 includes but is not limited to being rotatably connected to the cart 10 by a pin connection; the driving member 30 includes but is not limited to being rotatably connected to the cart 10 by a hinge.

[0073] In some embodiments, the first pressure stopper 2101 and the first pushing member both have a first preset angle with the horizontal plane, and the first preset angle is equal to the angle between the pressure cover 420 and the horizontal plane.

[0074] By setting the first preset angle equal to the angle between the pressure cover 420 and the horizontal plane, the first pressure blocking member 2101 and the first pushing member can respectively abut against the two pressure covers 420, and the two first pressure blocking members and the two first pushing members form four force points to ensure balanced force.

[0075] It should be noted that the angle between the pressure cover 420 and the horizontal plane is 6°, and the second preset angle is 6°.

[0076] It should also be noted that the line connecting the two first pressure blocking members passes through the center of the pressure cover, and the line is parallel to the Y direction; the line connecting the two first pushing members passes through the center of the pressure cover, and the line is parallel to the Y direction; thereby further ensuring the balanced force on the traction seat.

[0077] When disassembling the towing seat 40, the first-stage pressing member 2101 abuts against the gland 420 away from the fork head 470. The telescopic rod of the first pushing oil cylinder 2201 drives the first pushing member to move. The first pushing member applies pressure to the gland 420 to compress the gland 420, thereby compressing the towing rubber pad 430 inside the gland 420. The two glands 420 move towards each other until there is a gap between the gland 420 and the nut 440. Then, loosen the nut 440, and then remove the fork head 470, the gland 420, and the towing rubber pad 430 to complete the disassembly of the towing seat 40.

[0078] When assembling the towing seat 40, first buckle the two towing rubber pads 430 on the spherical body 4103 respectively, then install the two glands 420, and then pass the towing rod 450 through the glands 420 and the towing seat body 410. Then, after pre-tightening the nut until there is no gap, use the towing seat disassembly and assembly device. The first-stage pressing member 2101 abuts against the gland 420 away from the fork head 470. The telescopic rod of the first pushing oil cylinder 2201 drives the first pushing member to move. The first pushing member applies pressure to the gland 420 to compress the gland 420, thereby compressing the towing rubber pad 430 inside the gland 420. Until the distance between the gland 420 and the vertical plate 4102 of the towing seat body 410 reaches the preset distance, continue to tighten the nut 440 in place. The telescopic rod of the first pushing oil cylinder 2201 drives the first pushing member to move away from the gland 420, and then move the towing seat disassembly and assembly device away to complete the assembly operation.

It supplies oil according to the step-by-step requirements, and controls the direction, pressure and flow of the hydraulic oil, and is applicable to various hydraulic machines where the main machine and the hydraulic device can be separated; connecting the hydraulic station and the actuator (cylinder or oil motor) on the main machine with oil pipes, the hydraulic machine can realize various specified actions and working cycles. The specific structure and working principle of the hydraulic station are both prior arts, which will not be elaborated in this application.

[0086] It should also be noted that the preset spacing is 8 - 12 mm; the towing rod 450, the towing fork head 460, and the two gland covers 420 have an angle with the horizontal plane. For example, the angle is 6°. In addition, as Figure 3 shown, the horizontal plane is parallel to the XOY plane.

[0087] As Figure 3 、 Figure 4 shown, in some embodiments, the fixture 20 further includes a plurality of lifting guide rods 250 and a support plate 260; the plurality of lifting guide rods 250 are movably arranged on the trolley 10, and the lifting guide rods 250 extend in the height direction; the support plate 260 is arranged at the bottom of the lifting guide rods 250; wherein, the telescopic rod of the driving member 30 is connected to the support plate 260.

[0088] By the telescopic movement of the telescopic rod of the driving member 30, the fixture 20 is driven to move in the height direction, so that the fixture 20 can be sleeved on the towing seat 40 from top to bottom; by providing the lifting guide rods 250, it plays a guiding role in the lifting of the fixture 20, ensuring the smoothness and reliability of the movement.

[0089] As Figure 3 、 Figure 4 shown, in some embodiments, the fixing part 210 includes two second pressing members 2102 arranged at the bottom of the support plate 260, the two second pressing members 2102 are arranged at intervals, and the second pressing member 2102 is used to abut against the gland cover 420 away from the fork head 470.

[0090] As Figure 3 、 Figure 4 shown, in some embodiments, the clamping part 220 includes a second pushing oil cylinder 2203, a pushing guide rod 2204, a pushing vertical plate 2205 and two second pushing members 2206; the second pushing oil cylinder 2203 is arranged at the top of the support plate 260; the pushing guide rod 2204 is movably arranged on the support plate 260, and the pushing guide rod 2204 is respectively located on both sides of the second pushing oil cylinder 2203; the pushing vertical plate 2205 is respectively connected to the telescopic rod of the second pushing oil cylinder 2203 and the pushing guide rod 2204; the two second pushing members 2206 are respectively arranged on the pushing vertical plate 2205, the two second pushing members 2206 are arranged at intervals, and the second pushing member 2206 is used to abut against the gland cover 420 close to the fork head 470.

[0091] By making the second-stage pressing member 2102 abut against the gland 420 away from the fork head 470, the second pushing oil cylinder 2203 drives the second pushing member 2206 to move through the telescopic rod. The second pushing member 2206 applies pressure to the gland 420, compressing the gland 420. As a result, the traction rubber pad 430 inside the gland 420 is compressed, and the two glands 420 move towards each other, facilitating the disassembly and assembly of the traction seat 40 and improving the disassembly and assembly efficiency of the entire traction seat 40. By providing the pushing guide rod 2204, it guides the movement of the second pushing member 2206, ensuring the smoothness and reliability of the movement.

[0092] It should be noted that the second pushing oil cylinder 2203 drives the second pushing member 2206 to move, and the two second pushing members 2206 abut tightly against the gland 420, thereby driving the gland 420 to move.

[0093] It should also be noted that anti-slip patterns are provided on the second pushing member 2206, ensuring that the second pushing member 2206 abuts tightly against the gland 420 and increasing the friction between the second pushing member 2206 and the gland 420.

[0094] In some embodiments, both the support plate 260 and the pushing guide rod 2204 have a second preset angle with the horizontal plane, and the second preset angle is equal to the angle between the gland 420 and the horizontal plane.

[0095] By setting the second preset angle equal to the angle between the gland 420 and the horizontal plane, the second-stage pressing member 2102 and the second pushing member 2206 can respectively abut against the two glands 420, ensuring the force application.

[0096] It should be noted that the angle between the gland 420 and the horizontal plane is 6°, and the second preset angle is 6°.

[0097] When disassembling the traction seat 40, the second-stage pressing member 2102 abuts against the gland 420 away from the fork head 470. The telescopic rod of the second pushing oil cylinder 2203 drives the second pushing member 2206 to move. The second pushing member 2206 applies pressure to the gland 420, compressing the gland 420. As a result, the traction rubber pad 430 inside the gland 420 is compressed, and the two glands 420 move towards each other until there is a gap between the gland 420 and the nut 440. Then, loosen the nut 440, and then remove the fork head 470, the gland 420, and the traction rubber pad 430 to complete the disassembly of the traction seat 40.

[0098] When assembling the drawbar seat 40, first fasten the two drawbar rubber pads 430 onto the spherical body 4103 respectively, then install two gland covers 420, and then pass the drawbar 450 through the gland covers 420 and the drawbar seat body 410. Next, after pre-tightening the nut until there is no gap, use the drawbar seat disassembly and assembly device. The telescopic rod of the second push cylinder 2203 drives the second pusher 2206 to move. The second pusher 2206 applies pressure to the gland cover 420, compressing the gland cover 420, and thus the drawbar rubber pad 430 inside the gland cover 420 is compressed. Until the distance between the gland cover 420 and the vertical plate 4102 of the drawbar seat body 410 reaches the preset distance, continue to tighten the nut 440 in place. The telescopic rod of the second push cylinder 2203 drives the second pusher 2206 to move away from the gland cover 420, and then move the drawbar seat disassembly and assembly device away to complete the assembly operation.
