Description

Technical Field

[0001] The present application relates to the technical field of chain track disassembly and assembly, and in particular to a chain track disassembly and assembly machine. Background Art

[0002] The track chain assembly is mainly composed of track chain segments, pin shafts, pin sleeves, sealing components, thrust rings, retaining rings, etc. The track chain assembly is mainly used in the travel system of bulldozers and excavators.

[0003] CN215392313U discloses a hand-pressed portable chain link disassembling and assembling machine, which is mainly easy to carry and fully manually operated. It is suitable for simple on-site maintenance of small-pitch chains, but cannot cope with the renovation of the entire chain. Moreover, it cannot be fixed during press assembly and can only rely on manual labor. Summary of the invention

[0004] In view of the deficiencies in the prior art, one of the purposes of the present application is to provide a chain track disassembly and assembly machine, which has the advantage of being able to fix the chain track.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0006] A chain rail disassembling and assembling machine comprises a frame, a conveying platform is arranged on the frame, a pressing device is also arranged on the frame, the conveying platform is used to support and convey the chain rail, the pressing device comprises a driving assembly and an upper pressing plate, and the upper pressing plate and the driving assembly are hinged.

[0007] By adopting the above technical solution, during use, due to the presence of the drive assembly and the upper pressure plate, the chain rail can be fixed during the disassembly and assembly process. At the same time, the upper pressure plate and the drive assembly are hinged, so that during the fixing process, the upper pressure plate will adaptively deflect, thereby reducing the probability of the drive assembly loosening due to long-term stress.

[0008] In a preferred example, the present application can be further configured as follows: a guide column is provided on the upper pressure plate, a guide hole is provided on the frame for the guide column to pass through, the aperture of the guide hole is larger than the diameter of the guide column, and the drive assembly and the upper pressure plate are hinged by a ball joint.

[0009] By adopting the above technical solution, when the chain rail is pressed, it can rotate within a small range to ensure automatic leveling, reduce the probability of the driving component being tilted by force, and thus increase the service life of the entire structure.

[0010] In a preferred example, the present application can be further configured as follows: the conveying platform is provided with a lower pressure plate, the lower pressure plate and the upper pressure plate are arranged opposite to each other, and the upper pressure plate and the lower pressure plate cooperate to clamp the chain track.

[0011] By adopting the above technical solution, the upper pressing plate and the lower pressing plate cooperate to clamp the pin sleeve of the chain rail, thereby achieving a better fixing effect on the chain rail.

[0012] In a preferred example, the present application can be further configured as follows: the pressing device also includes a belt grinding mechanism, and the belt grinding mechanism is arranged on one side of the upper pressing plate.

[0013] By adopting the above technical solution, the existence of the belt grinding mechanism makes it possible to remove impurities and rust attached to the chain track pin shaft, thereby maintaining a good fixing effect.

[0014] In a preferred example, the present application can be further configured as follows: the chain rail first passes through the belt grinding mechanism and is then pressed by the upper pressure plate and the lower pressure plate. When the upper pressure plate and the lower pressure plate press the chain rail, the inclination of the guide column is judged. If there is an inclination, the position of the corresponding chain rail is recorded and a prompt is given.

[0015] By adopting the above technical solution, when there is a tilt, it indicates that the pin sleeve may be worn and the operator needs to pay attention to it.

[0016] In a preferred example, the present application can be further configured as follows: when there is a tilt, the direction and angle of the tilt are recorded, and when there are multiple identical records, a chain track abnormality prompt is issued.

[0017] By adopting the above technical solution, when there are multiple identical tilt angles and directions, it indicates that multiple pin sleeves have the same wear and tear, which requires the operator's attention.

[0018] In a preferred example, the present application can be further configured as follows: when the guide column is tilted, an image of the corresponding chain track is captured and judged. If there is a defect, a prompt is given; if it is an impurity, no prompt is given.

[0019] By adopting the above technical solution, when there are stubborn impurities on the pin sleeve (not removed after grinding), there is still a probability of tilting when pressed, so the chain track is imaged. If there are impurities, it means that the pin sleeve is not damaged, so no prompt is given.

[0020] In a preferred example, the present application can be further configured as follows: the downward pressure device includes a mounting plate, and the belt grinding mechanism and the upper pressure plate are both detachably connected to the mounting plate. When the belt grinding mechanism and the upper pressure plate are both installed on the mounting plate, the center of gravity of the mounting plate is located on one side of the belt grinding mechanism.

[0021] By adopting the above technical solution, that is, during the movement of the chain track, under the action of gravity, the mounting plate is in an inclined state, so that the grinding belt contacts the pin sleeve of the chain track, and the pin sleeve can be pre-grinded during the movement of the chain track.

[0022] In a preferred example, the present application can be further configured as follows: when the conveying platform drives the chain track to move, the belt grinding mechanism is in an inclined state, and the end located at a lower position contacts the chain track to grind the chain track.

[0023] By adopting the above technical solution, the pin sleeve can be pre-grinded during the movement of the chain track, so that the grinding effect of the pin sleeve is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] Reference Figure 1-Figure 3 , is a chain rail disassembly and assembly machine disclosed in the present application, comprising a frame 1, on which a conveying platform 4, a pressing device 2 and a pressing plate 3 are arranged. The conveying platform 4 comprises an electric screw 41 and a support plate 42, the support plate 42 and the frame 1 are slidably connected, the electric screw 41 is used to drive the support plate 42 to move, and the pressing plate 3 is connected to the frame 1 and is located above the support plate 42. The frame 1 is also provided with a lifting component 5 for driving the conveying platform 4 to rise and fall, and in this embodiment, the lifting component 5 is a hydraulic cylinder.

[0030] The pressing device 2 includes a driving assembly 21, a mounting plate 23, a guide column 22, an upper pressing plate 24 and a belt grinding mechanism 25. There are two guide columns 22 mounted on the mounting plate 23. The frame 1 is provided with a guide hole 11 for the guide column 22 to pass through. The diameter of the guide hole 11 is larger than the diameter of the guide column 22. The driving assembly 21 and the mounting plate 23 are hinged by a ball joint. The driving assembly 21 can be a hydraulic cylinder.

[0031] The upper pressing plate 24 and the belt grinding mechanism 25 are detachably mounted on the mounting plate 23 in sequence, and the overall center of the belt grinding mechanism 25, the upper pressing plate 24 and the mounting plate 23 is located at the belt grinding mechanism 25. In this embodiment, the belt grinding mechanism 25 is a belt grinder. The belt grinding mechanism 25 includes two pulleys.

[0032] The chain rail is placed on the support plate 42 and supported by the support plate 42. The pin sleeve of the chain rail is supported by the lower pressure plate 3. When the support plate 42 drives the chain rail to move, the lifting assembly 5 drives the conveying platform 4 to rise, so that the chain rail and the lower pressure plate 3 are separated. Then, the support plate 42 drives the chain rail to move a preset distance, and the lifting assembly 5 is reset. Since the overall center of the upper pressure plate 24 and the mounting plate 23 is located at the belt grinding mechanism 25, the mounting plate 23 is tilted, that is, the belt grinding mechanism 25 is in a tilted state, and the end located at the lower position contacts with the chain rail to grind the chain rail.

[0033] After the chain track passes through the belt grinding mechanism 25, it is pressed by the upper pressing plate 24 and the lower pressing plate 3. When the upper pressing plate 24 and the lower pressing plate 3 press the chain track, the inclination of the guide column 22 is judged. If there is an inclination, the position of the corresponding chain track is recorded, and the image of the corresponding chain track is collected and judged. If there is a defect, a prompt is given, and if it is an impurity, no prompt is given. When the chain track is fixed by the upper pressing plate 24 and the lower pressing plate 3, the belt grinding mechanism 25 contacts the pin sleeve and grinds the pin sleeve. When grinding the pin sleeve, in order to achieve a better grinding effect, in a horizontal state, the distance between the belt grinding mechanism 25 and the horizontal plane is smaller than the distance between the lower surface of the upper pressing plate 24 and the horizontal plane. During the movement, when a single pin sleeve is located between two pulleys, it moves downward, and the single pin sleeve contacts the grinding belt, causing the grinding belt to deform, thereby increasing the contact area with the pin sleeve and achieving a better grinding effect. When the upper pressing plate 24 and the lower pressing plate 3 fix the chain rail, a single pulley is located between two adjacent pin sleeves. At this time, one or more pin sleeves may exist between the two pulleys.

[0034] When there is a tilt, the direction and angle of the tilt are recorded. When there are multiple identical records, a chain track abnormality prompt is issued.

[0035] The implementation principle of this embodiment is: in use, by fixing the chain rail, it is convenient to disassemble the pin shaft of the chain rail.

[0036] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
