Description

Technical Field

[0002] A road roller, also known as a soil compactor, is a fill compaction machine used for road construction. In order to prevent the vibration of the steel wheel of the road roller from being transmitted to the machine body during operation, a set of shock absorber assemblies are often required to be respectively arranged on both sides of the steel wheel.

[0003] For example, a vibration roller steel wheel shock absorber protection mechanism is disclosed in the patent document with patent publication number CN207582251U, which includes a bracket, a shock absorber and a drive plate, one side of the shock absorber is connected to the bracket, and the other side of the shock absorber is connected to the drive plate. A bracket connecting ear is vertically arranged on the bracket, and a drive plate connecting ear is vertically arranged on the drive plate. The drive plate connecting ear is located on the upper side of the bracket connecting ear, and the drive plate connecting ear is fixedly connected to the bracket connecting ear by a fastener. According to the prior art documents, the steel wheel shock absorber achieves a shock absorbing effect by rigidly connecting the roller steel wheel to the drive plate and rigidly connecting the bracket to the front frame.

[0004] However, when assembling the shock absorber, in order to sequentially connect the bracket, shock absorber and drive plate, the position of the bracket needs to be flexibly adjusted so that the corresponding threaded holes of the three can be accurately connected. However, in the actual assembly process, due to the large number of connection holes and the heavy weight of the bracket and the drive plate, installation is more difficult; at the same time, the position of the two brackets is often manually adjusted and placed by the operator based on experience, and the precise connection between the corresponding connection holes of the three cannot be guaranteed. Therefore, the operator may need to repeatedly move the bracket to adjust its position, which is inefficient in installation.

[0034] In the working state, the operator clicks the corresponding button of the control mechanism according to the model and size of the shock absorber assembly to be assembled, thereby controlling the distance adjustment mechanism to perform the corresponding action, and then places the two brackets 5 of the shock absorber assembly at the corresponding positions of the distance adjustment mechanism respectively, and further fixes the two brackets 5 through the distance adjustment mechanism, so that under the action of the distance adjustment mechanism, it can be ensured that the two brackets 5 remain parallel and the distance between them just meets the assembly requirements, avoiding the repeated movement of the two for adjusting their positions in subsequent assembly. After that, each shock absorbing block 31 of the shock absorber assembly is fixedly installed on the two brackets 5 by bolts, and four shock absorbing blocks 31 are installed on each bracket 5.

[0036] The first driven gear 7 is fixed to one end of the corresponding rotating rod by a spline connection, and the other end of the rotating rod is movably inserted into the corresponding mounting hole of the annular mounting portion 8, so that the first driven gear 7 can rotate relative to the fixed frame 4 through the rotating rod.

[0037] The first servo motor 9 is fixed in the motor mounting hole, and its motor shaft drives the coaxially connected first driving gear 11 to rotate, thereby driving the first driven gear 7 to rotate synchronously, and then the first connecting plate 12 rotates accordingly, and finally the entire rotary mechanism achieves a flipping effect.

In this way, under the joint action of the first servo motor 9 and the second servo motor 16, the position of the distance adjustment mechanism can be flexibly adjusted, and then the angles of the bracket 5 fixed on the distance adjustment mechanism and the shock absorbing block 31 can be flexibly adjusted, so as to facilitate the docking of the side plate 6 with the corresponding connecting holes of the shock absorbing block 31.

The motor shaft is coaxially connected with the first ball screw 21 through a coupling, and the other end of the first ball screw 21 is movably connected with the matching assembly nut in the middle of the bottom surface of the second electro-permanent magnetic suction cup 32. When the third servo motor 20 is running, the first ball screw 21 rotates, and further through the active connection relationship between the first ball screw 21 and the assembly nut, and the active connection relationship between the second electro-permanent magnetic suction cup 32 and the second linear guide 18, the second electro-permanent magnetic suction cup 32 slides along the length direction of the third connecting plate 17, so that the first electro-permanent magnetic suction cup 19 and the second electro-permanent magnetic suction cup 32 are close to or away from each other while maintaining a parallel state.

[0043] The two brackets 5 of the shock absorber assembly are placed on the first electro-permanent magnetic chuck 19 and the second electro-permanent magnetic chuck 32 respectively, and driven by the first electro-permanent magnetic chuck 19 and the second electro-permanent magnetic chuck 32, the two brackets 5 are moved closer to or farther from each other accordingly.

Then the third servo motor 20 is controlled to work, so that its motor shaft drives the first ball screw 21 to rotate, and then drives the second permanent magnetic chuck 32 to move along the two second linear guides 18, so that it gradually approaches or moves away from the first permanent magnetic chuck 19, and finally moves to the specified position. Then, under the action of the positioning cylinder 22, each corresponding positioning pin 23 extends out of the top of the first electric permanent magnetic suction cup 19 and the second electric permanent magnetic suction cup 32, and then the mounting holes at the bottom of the two brackets 5 are docked with the corresponding positioning pins 23, so that the two brackets 5 are placed at the designated positions on the top of the first electric permanent magnetic suction cup 19 and the second electric permanent magnetic suction cup 32, respectively, so as to accurately position the two brackets 5, and then the first electric permanent magnetic suction cup 19 and the second electric permanent magnetic suction cup 32 are turned on and the corresponding brackets 5 are adsorbed and fixed respectively under the action of the two.
