In order to realize the corresponding nesting between the inner sleeve 11 and the outer sleeve 12, the relative positions between the inner sleeve 11 and the outer sleeve 12 are fixed so as to realize the supporting stress, for this purpose, referring to fig. 1, a plurality of positioning holes are formed in an equidistant array on the corresponding side walls of the inner sleeve 11 and the outer sleeve 12, and the aperture of each positioning hole is consistent, so that the relative positions between the inner sleeve 11 and the outer sleeve 12 are correspondingly adjusted according to the requirement of the erection height of a pump pipe, the positioning holes at the inner sleeve 11 are aligned with the positioning holes at the outer sleeve 12, and positioning bolts are penetrated between the positioning holes of the inner sleeve 11 and the outer sleeve 12, thereby limiting the relative movement between the inner sleeve 11 and the outer sleeve 12 and realizing the adjustment of the height of the lifting support. In other embodiments, the outer sleeve is fixedly connected with the top frame body, and the inner sleeve is nested into the tube body of the outer sleeve from the bottom end of the outer sleeve.
Because the concrete slurry pumped in the pump pipe has a certain pressure, the pressure slurry can cause a certain degree of reaction force to the pump pipe, so that the pump pipe is subjected to horizontal impact force, in order to avoid the adverse effect of the horizontal impact force on a template supporting system, as shown in fig. 1, two sliding grooves 2 are symmetrically and parallelly arranged on two sides of a lifting bracket 1, sliding pieces 3 are slidably embedded in the sliding grooves 2, wherein the notch of the two sliding grooves 2 is oppositely arranged, a pump pipe fixing frame 5 is arranged between the two sliding pieces 3 in the sliding grooves 2 on two sides through the notch, so that the sliding pieces 3 are fixedly connected with the pump pipe, the consistency of the movement of the pump pipe and the sliding pieces is realized, and the horizontal impact force borne by the pump pipe is reflected as the movement of the sliding pieces 3 along the sliding grooves 2; however, in order to counteract or buffer the horizontal impact force, in this example, the two ends of the chute 2 are respectively provided with a chute cover 21 for blocking, and a horizontal spring 4 is arranged between each chute cover 21 and the corresponding end surface of the slider, so when the pump pipe is driven by the horizontal impact force to move along the chute 2, each horizontal spring 4 between the chute cover 21 and the slider 3 correspondingly deforms, thereby realizing energy dissipation and achieving the effect of reducing or counteracting the horizontal impact force.
In addition, in order to improve the adaptability of the device, referring to fig. 1, the profile of the chute 2 is a cylinder, internal threads with a certain length are respectively formed at two end sides of the chute 2, external threads matched with the internal threads at the end sides of the chute 2 are formed at the side wall of each chute cover 21, so that threaded connection between the chute covers 21 and the chute 2 is realized, the deformation range of the corresponding horizontal spring is adjusted by controlling the screwing degree of the chute covers 21 at the end of the chute 2, the adjustment of the energy dissipation capacity of the spring is realized, and the problems that the horizontal movement amplitude of the pump pipe is overlarge and the horizontal impact force is difficult to reduce or offset due to the overlarge deformation amount of the spring are avoided.
