Description

Technical Field

[0001] The utility model relates to the field of concrete pipe production equipment, in particular to a leakage-proof concrete pipe pile mould. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. When producing concrete pipes, concrete pipe molds are required. However, existing concrete pipe pile molds have certain problems when used and still need to be continuously improved.

[0003] For example, a concrete pipe pile mold disclosed in the utility model with authorization announcement number CN219445518U includes an outer mold, an inner mold is arranged inside the outer mold, circular holes are provided on both sides of the outer mold, a sliding seat is slidably installed in the circular hole, a connecting groove is provided on the top inner wall and the bottom inner wall of the circular hole, a same fixing rod is fixedly installed on the inner walls of both sides of the connecting groove, a sliding seat is slidably installed on the fixing rod, one end of a first spring is fixedly installed on one side of the sliding seat, the other end of the first spring is fixedly installed on the inner wall of the connecting groove, one side of the sliding seat extends into the circular hole and is fixedly installed on the sliding seat, one side of the sliding seat extends to the inner mold and is fixedly installed with a clamp ring. By pulling the pull plate, the pull plate can drive the sliding seat to slide, the sliding of the sliding seat can drive the clamp ring to move, and the movement of the clamp ring can release the clamping of the inner mold, and the disassembly of the inner mold can be completed at this time.

[0004] When the device is in use, the elastic force of the first spring acts on the sliding seat, and then the sliding seat drives the clamp ring to approach the inner mold, thereby limiting the inner mold. However, the first spring has a certain elastic deformation ability and is prone to deformation during long-term use, which leads to a weakening of the elastic force of the first spring, thereby affecting the stability of the clamp ring's limiting fixation of the inner mold.

[0011] As a preferred technical solution of the utility model, two lifting rings for pulling the first inner mold and the second inner mold are symmetrically arranged at both ends of the first inner mold and the second inner mold.

[0013] Through the coordinated setting of the fixed seat and the bidirectional threaded screw, the limited rotation connection of the bidirectional threaded screw is realized, and through the coordinated setting of the bidirectional threaded screw and the two sliders, the movement adjustment of the two sliders approaching each other is realized.

The outer wall is provided with rough textures, and the contact friction between the hand and the adjusting button 13 can be increased by the setting of the rough textures, so that the bidirectional threaded screw 8 can be more conveniently rotated and adjusted by the adjusting button 13, and then two sliders 9 are symmetrically sleeved and connected to the outer thread of the bidirectional threaded screw 8, and four clamping rings 11 are evenly distributed in the outer mold 1, and then an arm 10 is hingedly connected between the surface of the clamping ring 11 and the surface of the two sliders 9, and four slide grooves 12 are opened on the side wall of the outer mold 1, and the arm 10 is movably passed through the slide grooves 12;

[0022] When replacing, installing and fixing the first inner mold 2 and the second inner mold 3 of different specifications and sizes, first close the first inner mold 2 and the second inner mold 3, and then place them in the outer mold 1, then adjust and rotate the bidirectional threaded screw 8 through the adjusting knob 13, and then drive the two sliders 9 to move closer to each other through the rotation of the adjusted bidirectional threaded screw 8, and then, through the cooperation of the two sliders 9 and the arm 10 that are close to each other, the two arm 10 push the clamping ring 11 toward the outer side wall of the first inner mold 2 and the second inner mold 3, and then the first inner mold 2 and the second inner mold 3 are limited and fixed through the four clamping rings 11 that move closer to each other;

[0023] As a further implementation of this embodiment, Figure 1-4 As shown, a trapezoidal groove 4 is provided on both sides of the first inner mold 2, and then a trapezoidal protrusion 5 is provided on both sides of the second inner mold 3, and the trapezoidal protrusion 5 can be matched and inserted with the trapezoidal groove 4, and the buckling arrangement of the trapezoidal groove 4 and the trapezoidal protrusion 5 can prevent part of the concrete slurry from leaking outward from the gap between the first inner mold 2 and the second inner mold 3, and finally two lifting rings 6 are symmetrically provided at both ends of the first inner mold 2 and the second inner mold 3, and the first inner mold 2 and the second inner mold 3 can be separated by the arrangement of the lifting ring 6, so as to facilitate the removal of the concrete pipe pile between the first inner mold 2 and the second inner mold 3;
