[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] like Figure 1-Figure 4 The horizontal pump pipe shock absorbing device shown comprises: a support base 1, a rubber shock absorbing pad 2 and a shock absorbing bracket; the top of the rubber shock absorbing pad 2 is provided with a U-shaped through groove 5 for supporting the horizontal pump pipe 6; the four corners of the bottom of the rubber shock absorbing pad 2 are respectively connected with a shock absorbing bracket, and the bottom of the shock absorbing bracket is connected with the support base 1; the shock absorbing bracket comprises a semi-rigid connecting rod 3 and a spring 4 movably sleeved on the outside of the semi-rigid connecting rod 3; the top of the semi-rigid connecting rod 3 is connected to the rubber shock absorbing pad 2, the bottom of the semi-rigid connecting rod 3 is connected to the support base 1, the top of the spring 4 abuts against the rubber shock absorbing pad 2, the bottom of the spring 4 abuts against the support base 1, and the inner wall of the spring 4 also contacts the semi-rigid connecting rod 3. A steel plate is embedded in the rubber shock absorbing pad 2, and the top of the semi-rigid connecting rod 3 of the shock absorbing bracket is connected to the steel plate.

[0022] The support base 1, the rubber shock-absorbing pad 2 and the shock-absorbing bracket form a stable support, which supports the horizontal pump pipe 6 and consumes the energy generated by the vibration of the horizontal pump pipe 6. Most of the vibration is consumed by the deformation of the rubber shock-absorbing pad 2 itself, and the other part of the vibration is transmitted to the spring 4 through the semi-rigid connecting rod 3, and the spring 4 vibrates and consumes energy. In addition, the spring 4 can also provide a restoring force for the semi-rigid connecting rod 3.

[0023] In some embodiments, a countersunk hole is provided at the bottom of the rubber shock-absorbing pad 2, and the top of the semi-rigid connecting rod 3 is inserted into the countersunk hole, and the insertion depth is less than the depth of the countersunk hole, and the side wall of the semi-rigid connecting rod 3 is frictionally matched with the hole wall of the countersunk hole, thereby consuming friction energy, and the countersunk hole provides space for the vertical displacement of the semi-rigid connecting rod 3, so that the rubber shock-absorbing pad 2 has a descending space, and the descending compression spring 4 of the rubber shock-absorbing pad 2 is deformed to absorb energy and reduce vibration.

[0024] The vibration energy of the horizontal pump pipe 6 is consumed by the shock-absorbing bracket and the rubber shock-absorbing pad 2, which can effectively reduce the impact of vibration during concrete pumping, avoid deformation of floor slab steel bars, and effectively ensure the quality of concrete molding and the stability of the inter-floor support system; and this device ensures that the horizontal pump pipe 6 does not directly contact the concrete floor slab during vibration, reduces damage to the floor slab, and plays a role in protecting the finished product.

[0025] A steel fastener 7 is provided at the top of the rubber shock-absorbing pad 2 and above the U-shaped through slot 5. A latch 8 is provided at one end of the steel fastener 7. A pin hole is provided at the top of the rubber shock-absorbing pad 2 on one side of the U-shaped through slot 5. The latch 8 is plugged into the pin hole. Specifically, the latch 8 is a rubber conical pin, and the pin hole is a conical hole. After the latch 8 is inserted into the pin hole, the side wall of the latch 8 is deformed and squeezed, and is clamped in the pin hole. Of course, after applying a certain external force, the latch 8 can be pulled out of the pin hole. The other end of the steel fastener 7 is fixedly connected to the top of the rubber shock-absorbing pad 2 on the other side of the U-shaped through slot 5. The fixing method can be a bolt 9 connection and fixing method. In this embodiment, there are two steel fasteners 7, and the two steel fasteners 7 are arranged at intervals along the length direction of the U-shaped through slot 5. After the pin 8 of the steel fastener 7 is plugged into the pin hole of the rubber shock-absorbing pad 2, the steel fastener 7 clamps the horizontal pump pipe 6 on the U-shaped through groove in the U-shaped through groove 5 to avoid displacement of the horizontal pump pipe 6 and ensure that the shock-absorbing device can fully play its role.

[0026] The bottom of the support base 1 is provided with a universal wheel 10. The universal wheel 10 is provided with a locking member, which is locked and fixed with the support base 1 or released and separated. When the locking member is released from the support base 1, the universal wheel 10 can be removed or moved, so that the universal wheel 10 is no longer installed on the support base 1, or leaves the bottom of the support base 1, so that the bottom of the support base 1 is directly located on the ground. When the universal wheel 10 is locked and fixed to the bottom of the support base 1 by using the locking member, it is convenient to move the shock absorbing device.

[0027] A wheel groove 11 is provided at the bottom of the support base 1, and the wheel groove 11 extends continuously to the side and top of the support base 1. The locking piece fixed on the universal wheel 10 is provided in the wheel groove 11 and movably cooperates with the wheel groove 11 along its extension direction to adjust the position of the universal wheel 10 in the wheel groove 11. The locking piece is locked and fixed with the wheel groove 11 or loosened and separated.

[0028] When the device does not need to be moved, the locking member is used to release the fixation between the universal wheel 10 and the support base 1, and the universal wheel 10 can move along the wheel groove 11, from the bottom of the support base 1 to the side of the support base 1, and then to the top of the support base 1, so that the universal wheel 10 does not contact the ground or the floor. The locking member in this embodiment can adopt the existing technology.

[0029] The setting of the universal wheel 10 improves the mobility of the device, making installation and turnover more convenient. The adjustable position of the universal wheel 10 enables the device to be applied to various working conditions, such as on the ground, floor surface, steel bars, etc., improving the versatility of the device.
