[0002] With the rapid development of the construction industry, concrete pumping technology has become an indispensable part of construction. Concrete pump pipes are key equipment for transporting concrete to various parts of the construction site, and their stability and safety are of vital importance.

[0003] However, the concrete pumping process is often accompanied by high pressure and strong mechanical vibration. These factors often cause the pump pipe to shift or be damaged, which not only affects the construction quality and efficiency, but may also cause safety accidents. The currently widely used fixing methods mainly rely on heavy support structures or temporary fixing measures. Although these methods provide a certain degree of stability, they lack flexibility and increase construction costs and labor intensity of workers. More importantly, these traditional methods are cumbersome during the installation and disassembly process, and often cannot effectively reduce or isolate the vibration during the pumping process.

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0023] The following describes an embodiment of the present invention based on its overall structure.

[0024] Example 1

[0025] A new type of shock-absorbing support for concrete pump pipes, such as Figure 1-4 As shown, it is mainly composed of a support beam 1, a support column 2, a first fastening half ring 3, a second fastening half ring 4, an upper connecting tube 7, a lower connecting tube 9, a shock-absorbing spring 10 and other components;

[0026] The support beam 1, serving as the foundation structure of the entire shock-absorbing support, is made of high-strength carbon steel and is manufactured through a hot-rolling process, exhibiting excellent bending and compression resistance. A fixed support column 2 is welded to the top of the support beam 1. The support column 2 is also made of high-strength carbon steel to ensure a secure connection. The first fastening half ring 3 and the second fastening half ring 4 are each made of Q345B low-alloy high-strength steel and are formed through a precision casting process. The inner walls of the rings are polished to reduce wear on the concrete pump pipe 14.

[0027] The first fastening half ring 3 and the second fastening half ring 4 are fastened together on both sides by fastening bolts 5. The bolts are 8.8 grade high-strength bolts to ensure the fastening effect. Through holes matching the fastening bolts 5 are opened on both sides of the first fastening half ring 3 and the second fastening half ring 4, and the edges of the through holes are chamfered to prevent stress concentration.

[0028] The upper connecting tube 7 and the lower connecting tube 9 are both made of seamless steel pipes. The top of the upper connecting tube 7 is fixedly connected to the support beam 1 through a connecting plate 6. The connecting plate 6 is made of Q235B steel plate with a thickness of 10mm. Both ends of the upper connecting tube 7 are fixed to the support beam 1 by connecting bolts 12. The connecting bolts 12 are selected from 6.8 grade to ensure a stable connection. Threaded holes that match the connecting bolts 12 are opened on the support beam 1 and the connecting plate 6. Washers are installed on the inner walls of the threaded holes. The washers are made of stainless steel to increase friction and prevent loosening.

[0029] Both sides of the upper connecting tube 7 and the lower connecting tube 9 are provided with through grooves. The design of the through grooves facilitates the installation and removal of the shock-absorbing spring 10 and also reduces the weight of the components. The outer wall diameter of the upper connecting tube 7 is consistent with the inner wall diameter of the lower connecting tube 9 to ensure the precision of the fit between the two. The shock-absorbing spring 10 is made of high-elasticity alloy spring steel and undergoes a heat treatment process to improve its elasticity and fatigue life. The shock-absorbing spring 10 is sleeved between the upper connecting tube 7 and the lower connecting tube 9 to provide a shock-absorbing and buffering effect for the concrete pump pipe 14.

[0030] The bottom of the lower connecting tube 9 is welded with a fixed support plate 8. The support plate 8 is made of 12mm thick Q345B steel plate through cutting and welding processes. Expansion bolts 13 are set at both ends of the support plate 8. The expansion bolts 13 are of M16 specification to ensure that the shock-absorbing support can be firmly fixed on the horizontal surface, thereby enhancing the overall stability and shock-absorbing performance.

[0031] Preparation before installation: At the concrete pump pipe 14 installation site, determine the installation location of the shock-absorbing support according to the construction drawings. Clean the installation location of debris and dust to ensure that the installation surface is flat and solid. Check the quality of the various components of the shock-absorbing support, such as whether the support beam 1 and support column 2 are deformed, whether the fastening bolts 5, connecting bolts 12, expansion bolts 13, etc. are complete and undamaged, and whether the shock-absorbing spring 10 is elastic. Prepare the tools required for installation, such as wrenches, screwdrivers, electric drills, etc.

[0032] Installation of the shock-absorbing support: First, fix the lower connecting tube 9 to the horizontal surface with the expansion bolt 13, use an electric drill to drill holes at the installation location, then insert the expansion bolt 13 into the hole, tighten the nut with a wrench, make the support plate 8 fit tightly against the ground to ensure the stability of the shock-absorbing support, sleeve the shock-absorbing spring 10 on the upper connecting tube 7, and then insert the upper connecting tube 7 into the lower connecting tube 9, so that the shock-absorbing spring 10 is in a compressed state, preparing for subsequent shock absorption work;

[0033] Connect and fix the upper connecting tube 7 to the support beam 1 through the connecting plate 6 and the connecting bolts 12. Align the connecting plate 6 with the threaded hole on the support beam 1, insert the connecting bolts 12, and tighten the nuts with a wrench to ensure a firm connection. Place the first fastening half ring 3 on top of the support column 2, then place the concrete pump pipe 14 on the first fastening half ring 3, and then place the second fastening half ring 4 on top of the concrete pump pipe 14, aligning the first fastening half ring 3 and the second fastening half ring 4. Fasten the two together with the fastening bolts 5, and use a wrench to tighten the fastening bolts 5 in sequence to ensure that the concrete pump pipe 14 is firmly fixed to the shock-absorbing support.

[0034] Usage and maintenance: During the concrete pumping process, the shock-absorbing spring 10 will absorb the vibration and impact force generated by the concrete pump pipe 14, reduce the vibration amplitude of the pump pipe, and reduce noise. Regularly check the various components of the shock-absorbing support, such as whether the fastening bolts 5, connecting bolts 12, and expansion bolts 13 are loose, and whether the shock-absorbing spring 10 is deformed or broken. If any bolts are loose, tighten them with a wrench in time. If there is a problem with the shock-absorbing spring 10, replace it with a new spring in time to ensure the normal operation of the shock-absorbing support. After the concrete pumping is completed, clean the concrete residue and dust on the surface of the shock-absorbing support to prevent it from corroding the components. For shock-absorbing supports that are used for a long time, the various connection parts can be lubricated regularly, such as applying lubricating oil on the bolt threads to reduce wear and extend the service life of the shock-absorbing support.

[0035] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention.
