Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to a paver track pin disassembly and assembly device. Background Technology

[0002] Tracked pavers are used frequently, under heavy loads, and in harsh working conditions, resulting in significant wear on their track chains. When the track chains are severely worn, they may come off during operation and travel, causing the paver to cease operation or movement. Wear primarily occurs on the bushings and pins, requiring timely replacement. However, severely worn bushings may prevent the pins from being easily disassembled, and the lack of specialized tools makes disassembly difficult.

[0003] In the actual process of disassembling and assembling track pins, the following problems exist: the existing track pin disassembly and assembly devices for pavers are usually large in size, inconvenient to carry, and time-consuming and laborious to operate, which greatly reduces the efficiency of disassembling and assembling track pins. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a paver track pin disassembly and assembly device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A paver track pin disassembly and assembly device includes a first support plate and a second support plate. The first support plate is disposed on the front side of the second support plate. Two first arc-shaped plates are symmetrically fixedly disposed on the front side of the first support plate, and two second arc-shaped plates are symmetrically fixedly disposed on the rear surface of the second support plate. Through holes are opened at both ends of the first and second support plates. Two parallel support rods are disposed between the first and second support plates. The ends of the two support rods pass through the corresponding through holes and extend out of the first and second support plates. Both ends of the two support rods are fixedly connected to the corresponding first and second support plates through connectors. A cylinder is disposed on the rear surface of the first support plate, and a material receiving pipe is fixedly disposed on the front surface of the second support plate. The cylinder and the material receiving pipe are collinear.

[0007] Preferably, the connector is a lock nut, and the support rod is provided with a threaded section that matches the nut.

[0008] Preferably, a magnet is fixedly provided on the rear side wall of the second support plate.

[0009] Preferably, the surface of the first arc-shaped plate is provided with a plurality of first weight-reducing grooves.

[0011] Preferably, a stop block is fixedly provided at the end of the piston rod of the cylinder.

[0012] The above technical solution has the following advantages:

[0013] 1. The paver track pin disassembly and assembly device connects the first support plate and the second support plate through support rods with threaded sections at both ends, which facilitates the quick disassembly and assembly of the device and makes it easy to carry the device.

[0014] 2. The track pin disassembly and assembly device of this paver can efficiently and conveniently disassemble and assemble track pins by placing the first support plate and the second support plate on both sides of the track and then extending the cylinder piston rod, thereby greatly improving work efficiency.

[0015] 3. The track pin removal and installation device of this paver has a receiving rod on the inner side of the second support plate, which facilitates the reception of track pins pushed out by the cylinder, prevents track pins from flying out, and makes operation safer.

Detailed Implementation

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] As shown in the attached figure, a paver track pin disassembly and assembly device includes a first support plate 1 and a second support plate 3. The first support plate 1 is disposed on the front side of the second support plate 3. Two first arc-shaped plates 2 are symmetrically fixedly disposed on the front side of the first support plate 1, and two second arc-shaped plates 4 are symmetrically fixedly disposed on the rear surface of the second support plate 3. Through holes are opened at both ends of the first support plate 1 and the second support plate 3. Two parallel support rods 7 are disposed between the first support plate 1 and the second support plate 3. The ends of the two support rods 7 pass through the corresponding through holes and extend out of the first support plate 1 and the second support plate 3. The ends of the two support rods 7 are fixedly connected to the corresponding first support plate 1 and the second support plate 3 through connectors. A cylinder 5 is disposed on the rear surface of the first support plate 1, and a material receiving pipe 10 is fixedly disposed on the front surface of the second support plate 3. The cylinder 5 and the material receiving pipe 10 are collinear.

[0022] As a preferred technical solution in this embodiment, the connecting component is a locking nut 9, and the support rod 7 is provided with a threaded section 8 that matches the nut 9. Obviously, other connection methods can also be used, such as pins.

[0023] As a preferred technical solution in this embodiment, a magnet 11 is fixedly provided on the rear side wall of the second support plate 3, which can attract the dislodged track pin and prevent the track pin from falling off.

[0024] As a preferred technical solution in this embodiment, the surface of the first arc plate 2 is provided with a plurality of first weight-reducing grooves 12, which can reduce the weight of the device.

[0025] As a preferred technical solution in this embodiment, the surface of the second arc plate 4 is provided with a plurality of second weight-reducing grooves 13, which can reduce the weight of the device.

[0026] As a preferred technical solution in this embodiment, a stop block 6 is fixedly provided at the end of the piston rod of the cylinder 5, and the stop block 6 can be quickly replaced when it is worn.

[0027] This invention significantly reduces the weight of the first arc-shaped plate 2 and the second arc-shaped plate 4 due to the design of the first weight-reducing groove 12 and the second weight-reducing groove 13, thus facilitating the carrying of the device. During operation, the first support plate 1 and the second support plate 3 are placed on both sides of the track. Then, support rods 7 are inserted into the through holes on both sides of the track pin, with the two ends of each support rod 7 inserted into the corresponding through holes of the first support plate 1 and the second support plate 3. Next, the cylinder 5 is placed on the rear surface of the first support plate 1, and then the nut 9 is threadedly connected to the threaded section 8, causing the receiving pipe 10 on the inner side of the second support plate 3 to abut against one side of the track. Then, the air supply to the cylinder 5 is turned on, controlling the piston rod of the cylinder 5 to extend, driving the abutment block 6 to abut against the track pin, thereby gradually pushing the track pin out. The receiving pipe 10 receives the disassembled track pin, minimizing the risk of the track pin flying out and making the operation safer. After the track pin enters the receiving pipe 10, the magnet 11 magnetically attracts the track pin, preventing it from falling out of the receiving pipe 10 when the device is removed. This allows for efficient and convenient disassembly and assembly of the track pin, thereby greatly improving work efficiency.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
