Description

Technical Field

[0001] The utility model relates to the technical field of prestressed concrete, in particular to a pile splicing positioning device for prestressed concrete piles. Background Technique

[0002] Concrete is one of the most important civil engineering materials in modern times. It is a kind of artificial stone prepared by mixing cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary in a certain proportion, uniformly stirred, densely formed, and cured and hardened. Prestressed concrete pipe piles can be divided into post-tensioned prestressed pipe piles and pre-tensioned prestressed pipe piles.

[0003] The pre-tensioned prestressed pipe pile is a kind of hollow cylindrical slender concrete precast member made by the pre-tensioned prestressed process and the centrifugal molding method. It is mainly composed of a cylindrical pile body, a head plate, a steel sleeve hoop, etc. When installing the prestressed concrete pipe pile, it is necessary to bury the embedded pile so that its top end is exposed by 90 cm, and then fix and install the connecting pile at the top end of the embedded pile to complete the pile splicing operation. However, in the prior art, it is necessary to ensure that the top end of the embedded pile is aligned with the bottom end of the connecting pile before splicing the embedded pile and the connecting pile. It is very difficult to judge whether the positions of the two are aligned by the naked eye. It is more complicated to use other equipment, and the adjustment process is more cumbersome. It is very difficult to fix the connecting pile in one step while ensuring the position accuracy between the embedded pile and the connecting pile.

[0004] The existing patent (publication number: CN219157654U) discloses a pile splicer for concrete pipe piles, including a pile splicing frame that fits with the concrete pipe pile. The characteristics are as follows: a clamping groove is arranged in the middle position of the pile splicing frame, the clamping groove is an arc-shaped groove hole structure, the surface of the clamping groove fits with the surface of the concrete pipe pile, fixed edges are arranged on both sides of the pile splicing frame, positioning screw holes are arranged on the fitting fixed edges, and the positioning screw holes are fixed by bolts passing through. Four positioning insertion holes are arranged in a rectangular array in the middle position of the pile splicing frame, and the positioning insertion holes are arranged through the fixing rods and extend through the through holes on the concrete pipe pile. By symmetrically arranging positioning insertion holes on both sides of the pile splicing frame, the positioning insertion holes are arranged through the fixing rods and extend through the concrete pipe pile, and the clamping grooves on both sides of the pile splicing frame are in contact with the surface of the concrete pile. Through this design, two adjacent concrete pipe piles can be fixed together. The inventor found the following problems in the process of realizing the present utility model: 1. Because the pile splicing positioning device is not convenient for visual adjustment for positioning, the positioning is inconvenient; 2. Because the positioning construction efficiency is low and the pile sinking quality cannot be guaranteed, in view of the actual engineering requirements and the limitations of the existing pile splicing methods, a pile splicing centering and positioning device matching the precast pipe pile is needed to complete, resulting in time-consuming and laborious alignment and positioning. Content of the Utility Model

[0007] Further preferably, the moving block forms a telescopic structure through the cylinder, and the moving block drives the fixed ring to move.

[0008] Further preferably, the gear forms a rotating structure through the rack, and the moving block drives the rack to move.

[0010] Further preferably, the clamping plate forms a telescopic structure through the folding plate, and when the fixed disc moves downward, the folding plates connected by the connecting seat cross to make the clamping plate move.

[0011] Further preferably, the support rod and the fixed plate are of an integral structure, and the support rod and the slide rail are of an integral structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0023] In this embodiment, asFigure 4 As shown, the moving block 202 forms a telescopic structure through the cylinder 201, and the moving block 202 drives the fixed ring 203 to move; because the cylinder 201 makes the moving block 202 drive the fixed ring 203 to move and be fixed, so that the moving block 202 can drive the fixed ring 203 to be fixed during use.

[0024] In this embodiment, as Figure 4 shown, the gear 205 forms a rotating structure through the rack 204, and the moving block 202 drives the rack 204 to move; because the moving block 202 makes the rack 204 move, driving the gear 205 to move, so that the gear 205 can move the same distance as the rack 204 during use.

[0025] In this embodiment, as Figure 1 、 Figure 2 and Figure 3 shown, the control rod 1 includes a threaded rod 101. The threaded rod 101 is fixedly connected to the lower part of the control rod 1. The top of the threaded rod 101 penetrates into the inside of the connecting cylinder 102. The connecting seat 103 is fixedly connected to the lower part of the connecting cylinder 102.
