[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 , Figure 2 The vertical pump pipe shock absorbing device shown includes a rubber shock absorbing ring 1, a spring connecting rod, an arc-shaped clamping plate 2 and a supporting connecting piece.

[0021] The rubber damping ring 1 is arranged horizontally, and a rectangular space is formed inside the rubber damping ring 1. The rubber damping ring 1 is a rectangular ring structure with a certain thickness and a main body made of rubber material. There are four spring connecting rods, which are distributed on the inner side of the rubber damping ring 1 along the circumference of the rubber damping ring 1, and the four spring connecting rods are distributed in the rectangular space inside the rubber damping ring 1.

[0022] The central axis of each spring connecting rod points to the center of the rubber damping ring 1, and one end of each spring connecting rod is connected to the rubber damping ring 1, and the other end is connected to the arc clamping plate 2. In this embodiment, every two spring connecting rods are connected to an arc clamping plate 2, and the two arc clamping plates 2 are arranged opposite to each other, and the two arc clamping plates 2 are surrounded to form a non-continuous circular channel. In some embodiments, each spring connecting rod is connected to an arc clamping plate 2, and four arc clamping plates 2 are surrounded to form a non-continuous circular channel. The circular channel is used for the vertical pump pipe to pass through, and the vertical pump pipe may also be referred to as a pump pipe or a concrete pump pipe or a concrete vertical pump pipe below. The end of the arc clamping plate 2 facing away from the spring connecting rod is a curved surface end, and the curved surface end is provided with a rubber pad 5. The rubber pad 5 is provided with an anti-slip protrusion 6. By providing the rubber pad 5, the damage caused to the concrete vertical pump pipe by the arc clamping plate 2 during operation is reduced, and the arc clamping plate 2 and the concrete vertical pump pipe are more closely fitted. Of course, since the size of the concrete vertical pump pipe is known and fixed, the diameter of the circular channel enclosed by the arc-shaped clamping plate 2 is determined according to the outer diameter of the pump pipe, so that the pump pipe can pass through the circular channel while the arc-shaped clamping plate 2 is clamped on the outer wall of the pump pipe to facilitate the transmission of vibration.

[0023] When the utility model is in use, the arc-shaped clamping plate 2 clamps the concrete pump pipe, and transmits the vibration generated when the pump pipe is working to the spring connecting rod, and then transmits it to the rubber shock-absorbing ring 1 through the spring connecting rod, thereby limiting the displacement of the concrete pump pipe and effectively reducing the amplitude of the concrete pump pipe vibration, thereby improving the molding quality of concrete.

[0024] The spring connecting rod includes a semi-rigid connecting rod and a spring sleeved outside the semi-rigid connecting rod. One end of the semi-rigid connecting rod is connected to the rubber damping ring 1, and the other end is connected to the arc-shaped clamping plate 2 to form a stable constraint; one end of the spring is pressed against the arc-shaped clamping plate 2, and the other end is pressed against the rubber damping ring 1. An annular steel plate is arranged on the inner side of the rubber damping ring 1, and the semi-rigid connecting rod is welded to the annular steel plate. The vibration of the pump pipe is transmitted to the semi-rigid connecting rod through the arc-shaped clamping plate 2, and then transmitted to the rubber damping ring 1. In this process, part of the vibration is transmitted to the spring, and the spring deforms to dissipate energy and reduce shock.

[0025] In some embodiments, a horizontal countersunk hole is provided on the inner side of the rubber shock-absorbing ring 1, and one end of the semi-rigid connecting rod is inserted into the countersunk hole, and the insertion depth is less than the depth of the countersunk hole; the semi-rigid connecting rod is frictionally matched with the hole wall of the countersunk hole, and the vibration is transmitted to the semi-rigid connecting rod, driving it to move, thereby rubbing with the hole wall of the countersunk hole to dissipate energy and reduce vibration, thereby improving the vibration reduction effect. At the same time, it is also beneficial to adjust the position of the arc splint 2, so that the pump tube can pass through the circular channel formed by the arc splint 2.

[0026] The outer side of the rubber damping ring 1 is connected with the supporting connector, and the supporting connector is used to be connected with a wall, column or floor opening of a building.

[0027] like Figure 1 , Figure 2 As shown, the supporting connector includes a connecting steel leg 7, a diagonal bracing steel leg 8 and a connecting bottom plate 9; the connecting steel leg 7 is horizontally arranged on the outside of the rubber shock absorbing ring 1, one end of the connecting steel leg 7 is connected to the rubber shock absorbing ring 1, and the other end is connected to the connecting bottom plate 9, the diagonal bracing steel leg 8 is obliquely arranged below the rubber shock absorbing ring 1, and the inclination angle of the diagonal bracing steel leg 8 is greater than 30 degrees, one end of the diagonal bracing steel leg 8 is connected to the lower end of the rubber shock absorbing ring 1, and the other end is connected to the connecting bottom plate 9, and the connecting bottom plate 9 is used to connect to the wall or column of the building. There are two connecting steel legs 7 and two diagonal bracing steel legs 8, respectively, and the two connecting steel legs 7 are arranged in parallel, and a diagonal bracing steel leg 8 is arranged below each connecting steel leg 7. A connecting bottom plate 9 is connected to one end of each connecting steel leg 7 and each diagonal bracing steel leg 8 away from the rubber shock absorbing ring 1, and a bolt hole is preset on the connecting bottom plate 9. The connecting bottom plate 9 is connected to the wall or column through the bolts passing through the bolt holes, so that the shock absorbing device is attached to one side of the wall or column.

[0028] like Figure 3 , Figure 4 As shown, the supporting connector includes four L-shaped steel plates 10, and the four L-shaped steel plates 10 are evenly distributed on the outside of the rubber shock-absorbing ring 1. One end of the L-shaped steel plate 10 is connected to the rubber shock-absorbing ring 1 by bolts, and the other end is used to connect to the edge of the floor opening of the building.
