Description

Technical Field

[0001] The present application relates to the technical field of chain rail disassembly and assembly, and in particular to a chain rail 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 disassembly and assembly machine, which is mainly easy to carry and fully manually operated. It is suitable for simple on-site maintenance work on small-pitch chains, but cannot cope with the renovation of the entire chain. Moreover, it cannot be fixed during pressing and can only rely on manual labor. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, one of the purposes of this application is to provide a chain rail disassembly and assembly machine, which has the advantage of being able to fix the chain rail.

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

[0006] A chain rail disassembly and assembly machine comprises a frame, a conveying platform is provided on the frame, and a pressing device is also provided 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. 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 track is compressed, it can rotate within a small range to ensure automatic leveling. The probability of the drive component being tilted due to force is reduced, thereby extending 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 pressing plate, the lower pressing plate and the upper pressing plate are arranged opposite to each other, and the upper pressing plate and the lower pressing plate cooperate to clamp the chain rail.

[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 a tilt, the position of the corresponding chain rail is recorded and a prompt is given.

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

[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 indicates 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, the belt grinding mechanism and the upper pressure plate are both detachably connected to the mounting plate, and 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 rail to move, the belt grinding mechanism is in an inclined state, and the end located at the lower position contacts the chain rail to grind the chain rail.

[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 with reference to the accompanying drawings.

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

[0030] The downward pressure device 2 includes a drive assembly 21, a mounting plate 23, guide posts 22, an upper pressure plate 24, and a belt grinding mechanism 25. Two guide posts 22 are mounted on the mounting plate 23. The frame 1 is provided with guide holes 11 for the guide posts 22 to pass through. The diameter of the guide holes 11 is larger than that of the guide posts 22. The drive assembly 21 and the mounting plate 23 are articulated via a ball joint. The drive assembly 21 can be a hydraulic cylinder.

[0031] The upper pressure plate 24 and the belt grinding mechanism 25 are detachably mounted on the mounting plate 23. The center of the belt grinding mechanism 25, the upper pressure 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 the chain rail to grind the chain rail.

[0033] After the chain rail 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 rail, the inclination of the guide column 22 is judged. If there is inclination, the position of the corresponding chain rail is recorded, and the image of the corresponding chain rail is captured and judged. If there is a defect, a prompt is given; if it is an impurity, no prompt is given. When the chain rail 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 the 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 the 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 be present 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 track abnormality prompt is issued.

[0035] The implementation principle of this embodiment is: during use, the chain rail is fixed, thereby facilitating the disassembly of 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 scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
