In the present embodiment, the damper mechanism 9 includes a trapezoidal block 91, a slide groove 92, a horizontal rod 93, a roller 94, a third spring 95, a second oil groove 96, a vertical rod 97, a support plate 98, an oil cylinder 99, a screw 910, a seal plate 911, and a fourth spring 912. Trapezoidal piece 91 is fixed mounting on spacing sleeve 7 inside bottom surface. The bottom surface of the support column 8 is formed in a shape to be fitted with the surface of the trapezoidal block 91. Two groups of sliding grooves 92 are symmetrically arranged on the trapezoidal block 91 in the front and back direction, and horizontal rods 93 are arranged in the sliding grooves 92 in a sliding mode. One end of the horizontal rod 93 is rotatably provided with a roller 94 which is matched with the bottom surface of the support column 8 in a rolling way, the other end of the horizontal rod 93 is horizontally and fixedly provided with a third spring 95, and the third spring 95 is fixedly connected to the end surface of the sliding groove 92. The top surface of the trapezoidal block 91 is provided with a vent groove communicated with the sliding groove 92. In the initial state, the horizontal rod 93 presses the roller 94 against the lowest position of the bottom surface of the supporting column 8 under the elastic force of the third spring 95. In the process of placing the plunger pump, the plunger pump drives the clamping mechanism 11, the top plate 10 and the support column 8 to descend, the bottom surface of the support column 8 pushes the roller 94, and the roller 94 pushes the horizontal rod 93 to slide in the sliding groove 92 to compress the third spring 95; so that the descending of the support column 8 and the plunger pump is buffered by the elastic force of the third spring 95, so that the plunger pump can descend slowly. After the plunger pump is stacked, the clamping function of the clamping mechanism 11 on the plunger pump is released, the elastic force of the third spring 95 pushes the horizontal rod 93 to slide in the chute 92 to restore to the original position, and meanwhile, the horizontal rod 93 pushes the support column 8 to ascend through the roller 94 to restore to the original height.

Before the plunger pump is stacked, the screw 910 is rotated to open the threaded hole on the rear end face of the oil cylinder 99. When the plunger pump drives the clamping mechanism 11, the top plate 10 and the support column 8 to descend, the support column 8 pushes the support plate 98 and the vertical rod 97 to descend, the vertical rod 97 extrudes hydraulic oil in the second oil groove 96, and the hydraulic oil flows into the oil cylinder 99 and pushes the sealing plate 911 to compress the fourth spring 912; therefore, the fourth spring 912 has a buffering effect on the descending process of the support column 8 and the plunger pump, and the descending speed of the plunger pump is further reduced. After the plunger pump is stacked, the clamping effect of the clamping mechanism 11 on the plunger pump is removed, the elastic force of the fourth spring 912 pushes the sealing plate 911 to return to the original position, the sealing plate 911 pushes hydraulic oil to flow back to the second oil groove 96, the hydraulic oil simultaneously pushes the vertical rod 97 to move upwards to return to the original position, and meanwhile the supporting plate 98 also returns to the original height. And finally, the screw hole on the rear end surface of the oil cylinder 99 is sealed by rotating the screw 910, so that the support column 8 is prevented from falling freely.
The concrete use steps of the stacking equipment after the plunger pump is cast in the embodiment are as follows: the screw 910 is rotated to seal the threaded hole on the rear end face of the oil cylinder 99, and then the plunger pump is clamped by the clamping mechanism 11. The universal wheel 23 is driven to roll by pushing the base 1, so that the position of the whole stacking equipment after the plunger pump is cast is adjusted. The screw 27 is rotated until the universal wheel 23 is contracted into the accommodating groove 21, and the bottom surface of the base 1 is in direct contact with the ground, so that the stacking equipment is stably placed on the ground after the plunger pump is cast. The screw 910 is rotated to open the threaded hole on the rear end face of the oil cylinder 99, so that the plunger pump and the support column 8 are slowly lowered under the action of the buffer mechanism 9. In the process, the first screw rod 4 is rotated to drive the first sliding plate 3 to horizontally slightly move along the front-back direction, so that the plunger pump is finely adjusted in the front-back direction; the second sliding plate 5 is driven to horizontally slightly move along the left-right direction by rotating the second lead screw 6, so that the plunger pump is finely adjusted in the left-right direction. After the plunger pump is stably placed in the storage box, the mounting plate 116 is pulled by the handle to compress the first spring 119, so that the sealing block 117 is separated from the vent hole on the outer end face of the sealing cylinder 112; the positions of the support rods 113 are adjusted, so that the support rods 113 are separated from the surface of the plunger pump, the clamping effect of the clamping mechanism 11 on the plunger pump is relieved, and the clamping mechanism 11, the top plate 10 and the support column 8 are restored to the initial height under the action of the buffer mechanism 9.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
