[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The following is in conjunction with the appendix Figure 1-3This application provides a further detailed description. An embodiment of this application discloses a clamping fixture for a road roller swing frame. It includes a base plate 1, with a first support 2 and a second support 3 on the upper surface of the base plate 1. The first support 2 includes a first clamping frame 201 and a first fixing frame 202. The first clamping frame 201 is connected to a first moving rod 203. One end of the first moving rod 203 reciprocates linearly toward the first fixing frame 202. Through the linear reciprocating movement of the first moving rod 203, the first support beam 501 placed between the first clamping frame 201 and the first fixing frame 202 is clamped, fixed, and released. The second support 3 includes a second clamping frame 301 and a second fixed frame 302. The second clamping frame 301 is connected to a second moving rod 303. One end of the second moving rod 303 moves linearly back and forth towards the second fixed frame 302. Through the linear back and forth movement of the second moving rod 303, the second support beam 502 placed between the second clamping frame 301 and the second fixed frame 302 is clamped, fixed, and released. The upper surface of the base plate 1 is also provided with a positioning block 4. The positioning block 4 is located on the side of the second support 3 away from the first support 2, so that the third support beam 503 of the roller swing frame 5 that is not clamped is blocked by the positioning block 4. The center point of the distance between the first clamping frame 201 and the first fixed frame 202, the center point of the distance between the second clamping frame 301 and the second fixed frame 302, and the positioning block 4 are located on the same straight line. This straight line is the center line, which corresponds to the center line of the crossbeam of the roller swing frame 5. Any part of the positioning block 4 coinciding with the center line can achieve the blocking effect, thereby realizing the positioning and limiting functions. The center point of the distance between the first clamping frame 201 and the first fixed frame 202 corresponds to the position of the first support beam 501 of the roller swing frame 5. The center point of the distance between the second clamping frame 301 and the second fixed frame 302 corresponds to the position of the second support beam 502 of the roller swing frame 5. The center point of the positioning block 4 corresponds to the position of the third support beam 503 of the roller swing frame 5, and is used to block the third support beam 503 during its translation along the centerline of the crossbeam of the roller swing frame 5. The first clamping frame 201 and the second clamping frame 301 are both located on one side of the centerline extension direction, and the first fixed frame 202 and the second fixed frame 302 are both located on the other side of the centerline extension direction. The linear movement direction of the first moving rod 203 and the second moving rod 303 is perpendicular to the centerline, so that the first moving rod 203 and the second moving rod 303 move in the same direction when clamping. The distance between the first support 2, the second support 3, and the positioning block 4 is set according to the actual distance between the three support beams of the roller swing frame 5 to be clamped.

[0018] Furthermore, the first moving rod 203 moves linearly and reciprocally towards the first fixed frame 202 at one end, wherein a clamping frame has a threaded hole, the first moving rod 203 is a threaded rod, and the first moving rod 203 is threadedly connected to the first clamping frame 201. Rotating the first moving rod 203 moves it closer to or further away from the first fixed frame 202. Similarly, the second moving rod 303 moves linearly and reciprocally towards the second fixed frame 302 at one end, wherein a second clamping frame 301 has a threaded hole, the second moving rod 303 is a threaded rod, and the second moving rod 303 is threadedly connected to the second clamping frame 301. Rotating the second moving rod 303 moves it closer to or further away from the second fixed frame 302.

[0019] Furthermore, in order to improve the rotation efficiency of the first moving rod 203 and the second moving rod 303, a handle is provided at the end of the first moving rod 203 away from the first fixed frame 202, and a handle is provided at the end of the second moving rod 303 away from the second fixed frame 302.

[0020] Furthermore, there are two or more first moving rods 203, which are arranged along the extension direction of the first clamping frame 201 to enhance the clamping effect.

[0021] Furthermore, there are two or more second moving rods 303, which are arranged along the extension direction of the second clamping frame 301 to enhance the clamping effect.

[0022] Furthermore, in this embodiment, the three support beams of the roller swing frame 5 are of the same size and specifications. Therefore, the clamping surface of the first fixed frame 202 is coplanar with the clamping surface of the second fixed frame 302, so that the three support beams of the roller swing frame 5 after being clamped are still in the same straight line.

[0023] Furthermore, the first moving rod 203 is provided with an elastic top block at one end near the first fixed frame 202, and the second moving rod 303 is provided with an elastic top block at one end near the second fixed frame 302, in order to reduce damage to the swing frame 5 of the clamped road roller.

[0024] Working principle: Place the base plate 1 on the ground, and hoist the roller swing frame 5 above the base plate 1, so that the extension direction of the three support beams of the roller swing frame 5 faces the base plate 1. During the process of lowering the height of the roller swing frame 5 to bring it closer to the base plate 1, the positioning block 4 is positioned between the second support beam 502 and the third support beam 503. Then, the roller swing frame 5 is moved horizontally towards the first support 2, so that the third support beam 503 abuts against the positioning block 4. At this time, the first support beam 501 and the second support beam 502 of the roller swing frame 5 are exactly within the clamping range of the first support 2 and the second support 3, respectively, realizing the positioning of the clamping position of the roller swing frame 5 by the positioning block 4. By operating the first moving rod 203 to move towards the first fixed frame 202 and operating the second moving rod 303 to move towards the second fixed frame 302, the roller swing frame 5 is clamped. During the clamping process, the positioning block 4 always abuts against the roller swing frame 5 to prevent the roller swing frame 5 from falling out of position, thereby achieving the limiting effect on the clamped roller swing frame 5.
