Description

Technical Field

[0001] This utility model relates to the field of concrete pole production technology, and in particular to a mold for producing concrete poles. Background Technology

[0002] Concrete poles are power support structures made of concrete and reinforcing steel bars or wires, primarily used in the construction of power transmission lines and communication facilities. Based on reinforcement technology, they can be divided into ordinary reinforced concrete poles and prestressed concrete poles; based on cross-sectional shape, they can be divided into annular cross-sections and square / irregular cross-sections. In the production of concrete poles, molds are typically used to cast the concrete.

[0003] After the concrete pole is cast, the upper mold can be lifted by a hoist to achieve demolding. However, when the hook of the external lifting equipment is hung on the hoist for lifting, there is no limiting structure between the hook and the hoist, which can easily cause the hook to slip on the hoist. This causes the upper mold to shake during the lifting process, resulting in poor demolding stability. Consequently, the surface of the concrete pole is easily damaged, affecting the production quality of the concrete pole. Utility Model Content

[0004] This invention proposes a mold for producing concrete poles to solve the problem of poor demolding stability of existing molds used in concrete pole production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mold for producing concrete poles includes an upper mold, a lower mold, and detachable end caps installed at both ends of the upper and lower molds. The top of the upper mold is provided with a pouring port and two hanging rods symmetrically distributed on both sides of the pouring port. The hanging rods are also provided with a limiting structure. The limiting structure includes a base plate fixed inside the bottom of the boom and a movable plate that can be raised and lowered inside the boom. The top of the movable plate is equipped with a clamping block and the bottom is fixed with a threaded rod. The top of the base plate is equipped with a rotatable screw cylinder, and a screw ring is installed on the outside of the screw cylinder. The threaded rod is screwed into the inside of the screw cylinder.

[0006] Preferably, the end cap is further provided with a positioning component for quickly positioning it with the upper mold and the lower mold, and the positioning component includes a plurality of inserts arranged in a ring array on one side of the end cap. Each of the plurality of inserts has a cavity, and each of the plurality of cavities is provided with a spring. Both ends of the spring are connected to a locking block. Both ends of the upper mold and the lower mold have insertion holes for inserting the inserts, and the inner wall of the insertion holes has locking holes for locking the locking blocks.

[0007] Preferably, a sealing ring is also installed on one side of the end cap, and sealing grooves that cooperate with the sealing ring are opened on both sides of the upper mold and the lower mold, so as to improve the sealing of the end cap after it is assembled with the upper mold and the lower mold, so as to facilitate the production of concrete poles.

[0008] Preferably, the inner top of the lifting rod is provided with an arc groove, and the top of the clamping block is provided with a clamping groove corresponding to the arc groove, which facilitates the limiting of the hook of the external lifting equipment, further facilitating the stable lifting of the upper mold and achieving stable demolding.

[0009] Preferably, the bottom two sides of the upper mold extend outward to form upper side edges, and the top two sides of the lower mold extend outward to form lower side edges, with locking bolts screwed between the upper side edges and the lower side edges.

[0010] Preferably, a plurality of positioning blocks are installed on the lower side and are evenly spaced along its length, and positioning holes corresponding to the plurality of positioning blocks are opened on the upper side, which can position the upper mold and the lower mold and facilitate the precise closing of the mold.

[0011] Preferably, the top of the upper mold and the bottom of the lower mold are both equipped with reinforcing frames, which can increase the strength of the upper and lower molds and ensure the normal production of concrete poles.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1-7 As shown, a mold for producing concrete poles includes an upper mold 1, a lower mold 8, and detachable end caps 6 installed at both ends of the upper mold 1 and the lower mold 8. The top of the upper mold 1 is provided with a pouring port 2 and two symmetrically distributed hanging rods 4 on both sides of the pouring port 2. A limit structure 5 is also provided on the hanging rods 4. The bottom sides of the upper mold 1 extend outward to form upper side edges 7, and the top sides of the lower mold 8 extend outward to form lower side edges 12. Locking bolts 11 are screwed between the upper side edges 7 and the lower side edges 12. Reinforcing frames 3 are installed at the top of the upper mold 1 and the bottom of the lower mold 8. The limiting structure 5 includes a base plate 51 fixed inside the bottom of the boom 4 and a movable plate 52 that can be raised and lowered inside the boom 4. A clamping block 53 is installed on the top of the movable plate 52 and a threaded rod 58 is fixed on the bottom. A rotatable screw cylinder 54 is installed on the top of the base plate 51, and a screw ring 55 is installed on the outside of the screw cylinder 54. The threaded rod 58 is screwed into the inside of the screw cylinder 54.

[0017] During the production of concrete poles, the upper mold 1 can be hoisted onto the lower mold 8 using external lifting equipment and lifting rod 4. The upper mold 1 and the lower mold 8 are then screwed together and fixed with locking bolts 11, so that the upper mold 1 and the lower mold 8 are closed. Then, end caps 6 are installed at both ends of the upper mold 1 and the lower mold 8 to complete the mold assembly. Then, concrete is poured into the mold through the pouring port 2, so that the concrete solidifies and forms in the mold. Then, the locking bolts 11 and end caps 6 are removed, and the upper mold 1 is lifted by external lifting equipment to complete the demolding. Finally, the formed concrete pole is removed from the lower mold 8, thus completing the production of the concrete pole. Furthermore, when the external lifting equipment lifts the upper mold 1 using the lifting rod 4, the hook of the external lifting equipment is hooked onto the lifting rod 4. At this time, the screw cylinder 54 can be rotated by the screw ring 55 to unscrew the threaded rod 58 from the screw cylinder 54. The threaded rod 58 then pushes the movable plate 52 upward, causing the clamping block 53 to press against the bottom of the hook, thereby limiting the hook and facilitating the stable lifting of the upper mold 1. This prevents the hook from sliding on the lifting rod 4 during the lifting of the upper mold 1, which could cause the upper mold 1 to shake. It also prevents damage to the surface of the concrete pole, thus helping to ensure the production quality of the concrete pole and achieve high-quality production of the concrete pole.

[0018] Furthermore, such as Figure 1 and Figure 2 As shown, a plurality of positioning blocks 10 are installed on the lower side 12 at equal intervals along its length direction, and positioning holes 13 corresponding to the plurality of positioning blocks 10 are opened on the upper side 7.

[0019] When the upper mold 1 and the lower mold 8 are closed, the positioning block 10 on the lower side 12 can be inserted into the positioning hole 13 on the upper side 7 to achieve positioning between the upper mold 1 and the lower mold 8, thereby facilitating the precise closing of the mold and enabling high-quality production of concrete poles.

[0020] Furthermore, such as Figure 3 and Figure 4 As shown, the top of the inner end of the rod 4 is provided with an arc groove 57, and the top of the clamping block 53 is provided with a clamping groove 56 corresponding to the arc groove 57.

[0021] When the clamping block 53 clamps and limits the hook of the external lifting equipment, the hook can be further limited by the cooperation of the arc groove 57 and the clamping groove 56, which facilitates the stable lifting of the upper mold 1 and is conducive to the stable demolding of the mold.

[0022] In another embodiment, such as Figures 1-4As shown, the end cap 6 is also provided with a positioning component for quick positioning with the upper mold 1 and the lower mold 8. The positioning component includes multiple insert blocks 14 arranged in a ring array on one side of the end cap 6. Each insert block 14 has a cavity, and each cavity has a spring 19. Both ends of the spring 19 are connected to a locking block 9. Both ends of the upper mold 1 and the lower mold 8 have insertion holes 16 for inserting the insert blocks 14, and the inner wall of the insertion hole 16 has a locking hole 18 for locking the locking block 9.

[0023] When assembling the end cap 6 with the upper mold 1 and the lower mold 8, the end cap 6 can be inserted into both ends of the upper mold 1 and the lower mold 8 through the cooperation of the insert block 14 and the insert hole 16. At this time, the locking block 9 corresponds to the locking hole 18, and under the action of the spring 19, the locking block 9 is locked into the locking hole 18 to limit the end cap 6 with the upper mold 1 and the lower mold 8. Then, the end cap 6 is fastened with the upper mold 1 and the lower mold 8 through fasteners, thereby realizing the quick mold closing, avoiding the problem of the end cap 6 shifting during installation and requiring fine adjustment, and is conducive to the precise mold closing, reducing the occurrence of burrs on both sides of the concrete pole, thereby improving the production quality of the concrete pole and realizing the high-quality production of concrete poles.

[0024] Furthermore, such as Figure 2 , Figure 5 and Figure 6 As shown, a sealing ring 15 is also installed on one side of the end cap 6, and sealing grooves 17 that cooperate with the sealing ring 15 are opened on both sides of the upper mold 1 and the lower mold 8.

[0025] When the end cap 6 is assembled with the upper mold 1 and the lower mold 8, the sealing ring 15 and the sealing groove 17 can ensure the sealing between the end cap 6 and the upper mold 1 and the lower mold 8, which can further reduce the occurrence of burrs on both sides of the concrete pole and facilitate the high-quality production of concrete poles.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
