Description

Technical Field

[0001] This application relates to the field of cement pole technology, and more specifically, to a cement pole production mold. Background Technology

[0002] The production process of cement pole molds involves splitting a cylindrical mold in half, filling it with concrete using a feeder, fixing the other half of the mold in place, and securing both ends of the mold. Then, a hook is used to lift the mold onto a centrifuge. The high-speed rotation of the centrifuge evenly spreads the cement onto the inner wall of the mold, making the cement pole hollow. This process is labor-intensive and resource-intensive, and the production efficiency is relatively low.

[0003] The prior art publication (announcement) number CN221850642U provides a cement pole production mold. In this related technology, by setting up an opening and closing mold assembly one and an opening and closing mold assembly two, after the upper mold and the lower mold are aligned, multiple bolts can be driven to rotate synchronously to fix or separate the upper mold and the lower mold. No manual operation is required, which saves time and effort, is convenient and quick, and saves the time of opening and closing the mold, which is conducive to improving production efficiency. Moreover, the synchronous rotation of multiple bolts has a good fixing effect.

[0004] Although the existing technical solutions described above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: when multiple bolts rotate synchronously, it is impossible to ensure that the tightening degree of multiple bolts is consistent when fixing or disassembling the upper and lower molds, and the speed of installation and use needs to be improved.

[0005] In view of this, we propose a mold for producing cement poles. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a cement pole production mold.

[0007] The cement pole production mold provided in this application adopts the following technical solution:

[0008] A cement pole production mold includes a hoisting support base. A supporting half-cylinder is fixedly connected to one side of the hoisting support base. Two closed plates are fixedly connected inside the supporting half-cylinder in a symmetrical structure. A closed half-cylinder is hinged to one side of the supporting half-cylinder. A wire threading plate is fixedly connected to one end of the closed half-cylinder. A steel cable is inserted inside the wire threading plate. A locking ring is fixedly connected between the beginning and end of the steel cable. A winding reel is inserted in the middle of the steel cable. A winch is fixedly connected to the outside of the winding reel. The winch is fixedly connected to one side of the hoisting support base.

[0009] By adopting the above technical solution, when the winch drives the winding wheel of the inserted steel cable to retract and release the cable, the cable can achieve closure between the closed half-cylinder and the supporting half-cylinder, ensuring the quickness of setting the limit position of the cement pole inside the mold.

[0010] As an optional solution to the technical solution in this application, the hoisting support has two hinge seats fixedly connected to one side in a symmetrical structure, a fixed pulley is rotatably connected to the middle of the hinge seat, and a wire harness ring is fixedly connected to one side of the hinge seat.

[0011] By adopting the above technical solution, and by installing a fixed pulley and a cable tie ring inside the hinge seat, it is possible to ensure that the steel cable pulled during the closing and flipping action of the closed half-cylinder can maintain stable frictional contact with the fixed pulley under the guidance of the cable tie ring, thus ensuring the guide and limit of the fixed pulley on the steel cable.

[0012] As an optional solution to the technical solution of this application, the outer side of the wire harness ring has multiple through holes in a ring-shaped, equally spaced structure, and each through hole is embedded with a columnar talc column, which is formed by the solidification of a mixture of lubricating grease and talc powder.

[0013] By adopting the above technical solution, talc columns formed by the solidification of lubricating grease and talc powder are distributed and embedded inside the cable tie ring, which can lubricate the steel cable and the cable tie ring when they are subjected to tensile friction, optimize the contact fit between the two, and reduce the wear of the steel cable.

[0014] As an optional solution to the technical solution in this application, two dampers are installed in a symmetrical structure with hinges between the supporting half-cylinder and the closed half-cylinder.

[0015] By adopting the above technical solution, the damper can improve the elastic support force of the closed half-cylinder closed on the surface of the supporting half-cylinder, ensuring that after the steel cable is released, the closed half-cylinder can be opened under the elastic reset of the damper, which makes it easy to put the steel bar frame into the mold for use.

[0016] As an optional solution to the technical solution of this application, the cross-section of the threading plate is set in an arc-shaped structure with a high center and low ends.

[0017] By adopting the above technical solution, the cross-section of the cable threading plate is set with an arc-shaped structure that is high in the center and low at both ends. This facilitates the tightening and positioning of the cable threading plate when the steel cable is wound and tightened, ensuring the tightness of the closure between the supporting half-tube and the closing half-tube.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application utilizes a winch to drive a winding reel for the inserted steel cable to retract and release the cable, thereby achieving the closure of the cable between the closed half-cylinder and the supporting half-cylinder, ensuring the quick and easy setting of the limit position for the cement pole inside the mold.

[0020] 2. This application utilizes the arc-shaped structure of the cable guide plate with a high center and low ends to facilitate the tensioning and limiting of the cable when it is wound and tightened, thus ensuring the tightness of the closure between the supporting half-tube and the closing half-tube.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1-3 The cement pole production mold described in this application includes a hoisting support base 1. A supporting half-cylinder 2 is fixedly connected to one side of the hoisting support base 1. Two closed plates 3 are fixedly connected inside the supporting half-cylinder 2 in a symmetrical structure. A closed half-cylinder 4 is hinged to one side of the supporting half-cylinder 2. A wire threading plate 5 is fixedly connected to one end of the closed half-cylinder 4. A steel cable 6 is inserted inside the wire threading plate 5. A locking ring 7 is fixedly connected between the beginning and end of the steel cable 6. A winding wheel 8 is inserted in the middle of the steel cable 6. A winch 9 is fixedly connected to the outside of the winding wheel 8. The winch 9 is fixedly connected to one side of the hoisting support base 1.

[0029] This cement pole production mold, by using a winch 9 to drive the winding wheel 8 of the inserted steel cable 6 to retract and release the cable, can realize the closure between the cable 6 and the closed half-cylinder 4 and the supporting half-cylinder 2, ensuring the quick setting and limiting of the cement pole inside the mold.

[0030] Reference Figure 4 and Figure 5 In the cement pole production mold described in this application embodiment, the hoisting support seat 1 has two hinge seats 11 fixedly connected to one side in a symmetrical structure. A fixed pulley 12 is rotatably connected to the middle of the hinge seat 11, and a wire harness ring 13 is fixedly connected to one side of the hinge seat 11. The wire harness ring 13 has multiple through holes with an annular and equally spaced structure on its outside. A columnar talc column 14 is embedded in the through hole. The talc column 14 is formed by mixing and solidifying lubricating grease and talc powder.

[0031] This cement pole production mold, by utilizing the fixed pulley 12 and cable tie ring 13 installed inside the hinge seat 11, can ensure that the steel cable 6 pulled during the closing and flipping action of the closed half cylinder 4 can maintain stable frictional contact with the fixed pulley 12 under the guidance of the cable tie ring 13, ensuring the guiding and limiting of the fixed pulley 12 on the steel cable 6. The talc columns 14, formed by the solidification of lubricating grease and talc powder, are distributed and embedded inside the cable tie ring 13, which can lubricate the steel cable 6 when it is subjected to tensile friction action with the cable tie ring 13, optimize the contact fit between the two, and reduce the wear of the steel cable 6.

[0032] Reference Figure 2 and Figure 1 In the cement pole production mold described in this application embodiment, the supporting half-cylinder 2 and the closed half-cylinder 4 are symmetrically connected and hinged with two dampers 21.

[0033] The cement pole production mold utilizes a damper 21 to enhance the elastic support force of the closed half-cylinder 4, which is closed on the surface of the supporting half-cylinder 2. This ensures that after the steel cable is released, the closed half-cylinder 4 can be opened under the elastic reset of the damper 21, making it easier to insert the steel reinforcement frame into the mold.

[0034] Reference Figure 3 In the cement pole production mold described in this application embodiment, the cross-section of the wire threading plate 5 is set in an arc-shaped structure with a high center and low ends.

[0035] The cement pole production mold utilizes the arc-shaped structure of the wire guide plate 5, which is high in the center and low at both ends. This allows the steel cable 6 to be tightened and bound together with the wire guide plate 5 when it is wound up, ensuring the tightness of the closure between the supporting half-cylinder 2 and the closing half-cylinder 4.

[0036] Working principle: When it is necessary to place the pole steel cage inside the mold formed by the supporting half cylinder 2 and the closed half cylinder 4 for casting to form the electric pole structure, the operator drives the winch 9 to release the steel cable 6 wound on the outside of the winding reel 8.

[0037] As the steel cable 6 is released, the compressed damper 21 extends, thereby pushing the closed half-cylinder 4 that is attached to the closed support half-cylinder 2 to expand outward, thus unfolding the support half-cylinder 2 used to place the steel cage.

[0038] Finally, after placing the steel cage into the supporting half-cylinder 2, tighten the steel cable 6, close the supporting half-cylinder 2 and the closed half-cylinder 4 to form a mold structure, inject concrete slurry, and use lifting equipment to lift the hoisting support seat 1 and place it in the centrifugal equipment for centrifugal mixing and solidification.
