[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0031] like Figure 1-5 As shown, the present invention provides a track shoe tensioning device based on hydraulic drive, which mainly includes: a hydraulic cylinder 110, a mounting seat 120, a first pulling arm 130, a second pulling arm 140 and a guide rod 150.

[0032] A piston rod 111 extends from one end of the hydraulic cylinder 110. A mounting base 120 is loosely mounted on the piston rod 111 and is fixedly mounted on the end surface of the hydraulic cylinder 110 extending from the piston rod. In this embodiment, a connecting flange 110a is provided on the end surface of the hydraulic cylinder 110. The mounting base 120 is the same size as the connecting flange 110a and is fixedly connected to the connecting flange 110a via bolts.

[0033] The first arm 130 is loosely mounted on the piston rod 111 and fixedly connected to the mounting base 120 via bolts. The second arm 140 is fixedly connected to the free end of the piston rod 111 (the end not connected to the piston) and is positioned opposite the first arm 130. The second arm 140 moves synchronously with the piston rod 111, allowing the second arm 140 to move closer to or further away from the first arm 130.

[0034] The first arm 130 has a first groove 131 on the side facing the second arm 140. The second arm 140 has a second groove 141 symmetrical to the first groove 131. The first groove 131 and the second groove 141 are arc-shaped grooves, sized to match the track pins of the track shoe to be tensioned. The first groove 131 and the second groove 141 are located outside the outer wall of the hydraulic cylinder 110 for ease of operation. During operation, the first groove 131 and the second groove 141 respectively engage with the track pins of the two track shoes to be tensioned.

[0035] In this embodiment, the first pull arm 130 and the second pull arm 140 are both made of 45-gauge steel, which has good strength and toughness.

[0036] Preferably, the hydraulically driven track shoe tensioning device further includes a guide rod 150. Guide rod 150 is arranged parallel to piston rod 111, and one end of guide rod 150 is fixedly connected to mounting base 120. The second tensioning arm 140 is movably connected to guide rod 150, which guides the movement of second tensioning arm 140, thereby improving the stability of the track tensioning device.

[0037] In this embodiment, a guide slider 160 is further provided, which is matched and mounted on the guide rod 150 and can slide along the guide rod 150. The guide slider 160 is fixedly connected to the free end of the piston rod 111, and the second pulling arm 140 is fixedly connected to the guide slider 160.

[0038] A connecting sleeve 161 is fixedly provided on one side of the guide slider 160 and is fixedly sleeved on the free end of the piston rod 111 through the connecting sleeve 161 to ensure the stability of the connection. The second pulling arm 140 is fixedly connected to the other side of the guide slider 161 by bolts.

[0039] The hydraulic cylinder 110 is provided with two quick connectors 112 for connecting to a hydraulic pump, wherein a first pull arm 130 and a second pull arm 140 are arranged toward a side away from the quick connector 112 to avoid interference between the quick connector 112 and the track shoe during operation.

[0040] In one embodiment, the hydraulically driven track shoe tensioning device is further provided with a handle (not shown in the figure), which is mounted on the mounting base 120 to facilitate operation.

[0041] The working process of the hydraulically driven track shoe tensioning device is as follows: after the track shoe is replaced, the first groove 131 of the first pulling arm 130 and the second groove 141 of the second pulling arm 140 are respectively matched and engaged with the track pins of the two track shoes to be tightened, the hydraulic cylinder 110 is turned on, and the piston rod 111 of the hydraulic cylinder drives the second pulling arm 140 to move toward the first pulling arm, so that the two track shoes are close to each other, thereby achieving the tightening of the track shoes.

[0042] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
