The spring seats fixed with the vertical connecting plates and the inner walls of the rectangular vertical steel plate frames are arranged at the two ends of the damping springs.
Through setting up the spring holder in this structural design, make damping spring's connection more reasonable reliable.
The damping springs are internally provided with screw rods penetrating through the vertical connecting plates and the rectangular vertical steel plate frames, locking nuts tightly attached to the outer walls of the vertical connecting plates and the rectangular vertical steel plate frames are screwed on the screw rods, and the damping springs on any side in the front and back and any side in the left and right are compression springs.
In this structure setting, through adjusting lock nut, when making the pump line place in the centre, the damping spring of arbitrary side about and around arbitrary side is in the compression state, and compresses 1/3 length, and damping spring of other both sides is in natural state, ensures that the pump line is installed fixed firm not hard up in damping device.
The invention has reasonable and reliable structural design, greatly reduces the disturbance to the horizontal direction and the vertical direction of the floor caused by the impact force of the pump pipe when the pump pipe penetrates through the floor, and greatly improves the damping effect, thereby avoiding the problem of fatigue damage of the floor in the middle layer, ensuring the construction quality of the floor concrete and having the advantages of simple structure, convenient processing and repeated use.
