Description

Technical Field

[0001] This utility model relates to the field of cement pole technology, and in particular to a cement pole mold. Background Technology

[0002] The factory mainly uses centrifugal molding technology to mass-produce cement poles. In the production process, steel reinforcement and concrete are injected into cement pole molds, and then the molds are placed in a centrifuge for high-speed rotation. Centrifugal force makes the concrete evenly adhere to the inner wall, forming a hollow structure. After steam curing and demolding, the cement pole production is completed.

[0003] Currently, traditional molds typically employ a two-piece semi-circular structure (upper and lower molds), connected by tongue and groove joints and bolts to form a cylindrical shape. After closing, this creates a cylindrical cavity for molding the cement pole. However, demolding the cement pole requires opening the upper mold first. Since the lower mold covers half of the cement pole, ordinary lifting clamps cannot effectively hold it. Workers must manually push the lower mold with tools like pry bars to flip it over, then pry the cement pole out. This process is not only time-consuming and labor-intensive, but also increases the risk of stress damage when the cement pole falls to the ground. Furthermore, existing molds often have evenly spaced cavities, limiting their production to cylindrical cement poles. Custom-made tapered molds are required to produce tapered cement poles, increasing production costs. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a cement pole mold in which the cylinder is composed of multiple first templates spliced ​​together. During demolding, by disassembling two of the first templates, the remaining first templates cover less than half of the cement pole's surface area. This allows the cement pole to be directly clamped by a hoisting clamp for demolding, saving time and effort, improving work efficiency, and reducing the risk of damage to the cement pole.

[0006] To achieve the above objectives, the first aspect of this utility model provides a cement pole mold, comprising: multiple first templates, multiple sets of first locking mechanisms, multiple rotating blocks, multiple second templates, and multiple sets of second locking mechanisms. The multiple first templates are assembled into a cylindrical shape, and each first template has a first end plate on one of its two short sides. The multiple sets of first locking mechanisms are respectively disposed on the two long sides of the corresponding first templates. The multiple rotating blocks are respectively disposed on the outer curved surfaces of the corresponding first templates, and multiple adjacent rotating blocks are combined into a disc shape. The multiple second templates are respectively disposed on one side of the inner curved surface of the corresponding first templates and are combined into a cylindrical shape, with the inner curved surfaces of the multiple second templates combined into a conical cavity. The multiple sets of second locking mechanisms are respectively disposed between the corresponding second templates and the first end plates.

[0007] In addition, the cement pole mold proposed above according to this utility model may also have the following additional technical features: Specifically, each set of the first locking mechanism includes two fixing plates, multiple screws, and multiple screw sleeves. The two fixing plates are respectively disposed on the two long sides of the first template, and each fixing plate has multiple grooves. The multiple screws are rotatably connected to the corresponding grooves on one side of the fixing plate. The multiple screw sleeves are threadedly connected to the corresponding screws.

[0008] Specifically, a slot is provided on one side of the fixing plate, and a matching card is provided on the other side of the fixing plate.

[0009] Specifically, each group of the second locking mechanism includes two second end plates, multiple bolts, and multiple nuts. The two second end plates are respectively disposed on the two short sides of the corresponding second template and coincide with the corresponding first end plate. The multiple bolts pass through the corresponding first end plate and the second end plate respectively. The multiple nuts are respectively connected to the corresponding bolts.

[0010] Specifically, each of the first templates has ribs on its outer curved surface.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The cement pole mold of the present invention is composed of multiple first templates spliced ​​together. When demolding, by disassembling two of the first templates, the remaining first template covers less than half of the surface area of ​​the cement pole. Thus, the cement pole can be directly clamped by the hoisting clamp for demolding without the need for manual turning of the mold, saving time and effort, improving work efficiency, and reducing the risk of damage to the cement pole.

[0012] 2. The cement pole mold of this utility model can connect the second template to the first template through the second locking mechanism to form a conical mold cavity, thereby producing conical cement poles as needed, which greatly improves practicality and saves production costs.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] The following describes the cement pole mold of an embodiment of the present invention with reference to the accompanying drawings.

[0019] like Figures 1-5 As shown, the cement pole mold of this utility model embodiment may include: multiple first templates 1, multiple sets of first locking mechanisms 2, multiple rotating blocks 3, multiple second templates 4, and multiple sets of second locking mechanisms 5.

[0020] Multiple first templates 1 are spliced ​​together to form a cylindrical shape, and each first template 1 has a first end plate 101 on its two short sides.

[0021] It should be noted that the number of first templates 1 described in this embodiment is 3, which reduces the coverage area of ​​each first template 1 on the cement rod, making it easier to demold later. After the first templates 1 are spliced ​​and combined into a cylinder, an equally spaced cavity is formed inside, which is used to produce columnar cement rods.

[0022] Multiple sets of first locking mechanisms 2 are respectively set on the two long sides of the corresponding first template 1.

[0023] It is understandable that the first locking mechanism 2 can lock and fix the first templates 1 together in pairs.

[0024] Multiple rotating blocks 3 are respectively set on the outer curved surface of the corresponding first template 1, and multiple adjacent rotating blocks 3 are combined into a disk shape.

[0025] It should be noted that each first template 1 described in this embodiment is provided with at least 3 rotating blocks 3, which are combined to form at least 3 discs to ensure the stability of the mold when it rotates on the centrifuge.

[0026] Multiple second templates 4 are respectively set on one side of the inner curved surface of the corresponding first template 1 and combined into a cylindrical shape. The inner curved surfaces of the multiple second templates 4 are combined into a conical cavity.

[0027] It should be noted that the number of second templates 4 described in this embodiment is 3, and the taper of their inner curved surfaces is set according to actual production needs.

[0028] Multiple sets of second locking mechanisms 5 are respectively set between the corresponding second template 4 and the first end plate 101.

[0029] Understandably, the second locking mechanism 5 can fix the first template 1 and the second template 4 together, ensuring the stability of the second template 4, and is used to produce tapered cement rods.

[0030] Specifically, during the production of cement poles, the relevant personnel first lock and fix the two first templates 1 with the first locking mechanism 2, and place them on the processing table with their openings facing upwards. Then, a release agent is applied to the inner walls of the two first templates 1, the steel reinforcement skeleton is placed inside the two first templates 1, and concrete is injected. Then, the last first template 1 is fastened to the upper part of the two first templates 1 and locked and fixed by the first locking mechanism 2 respectively.

[0031] The mold is held in place by an external hoisting clamp (such as a gantry crane) and transported onto the centrifuge. The rotating block 3 contacts the centrifuge wheel, and the centrifuge is started to drive the mold to rotate at high speed. Centrifugal force is used to make the concrete evenly adhere to the inner wall and form a hollow cement rod. After centrifugation, the mold is sent into a steam bath and cured at high temperature for 5-9 hours to accelerate the curing of the concrete and reach the demolding strength.

[0032] Finally, the mold is removed, with one of the first templates 1 facing down and the other two first templates 1 facing up. The relevant personnel open the corresponding first locking mechanism 2 to remove the two upper first templates 1. At this time, the lower first template 1 covers one-third of the surface area of ​​the cement pole. Then, the cement pole is directly clamped by the hoisting clamp and hoisted to complete the demolding of the cement pole.

[0033] As a possible scenario, when a factory needs to produce tapered cement poles, three second templates 4 can be installed into the corresponding first templates 1 through the second locking mechanism 5. After the first templates 1 are connected through the first locking mechanism 2, the inner curved surfaces of the second templates 4 combine to form a tapered cavity. By repeating the above operation steps, tapered cement poles can be produced, thus eliminating the need for the factory to additionally customize and purchase tapered cement pole molds, which greatly saves production costs.

[0034] In one embodiment of this utility model, such as Figure 3 and Figure 5 As shown, each first locking mechanism 2 includes two fixing plates 201, multiple screws 202, and multiple screw sleeves 203.

[0035] Two fixing plates 201 are respectively set on the two long sides of the first template 1. Each fixing plate 201 has multiple grooves 2011. Multiple screws 202 are rotatably connected to the corresponding grooves 2011 on one side of the fixing plate 201. Multiple screw sleeves 203 are threadedly connected to the corresponding screws 202.

[0036] A slot 6 is provided on one side of the fixing plate 201, and a matching card 7 is provided on the other side of the fixing plate 201.

[0037] It should be noted that the screw sleeve 203 described in this embodiment is provided with a first handle, which facilitates manual tightening by relevant personnel.

[0038] Specifically, when assembling the first template 1, one of the first templates 1 is inserted into the slot 6 of another first template 1 through the clamping plate 7, so that the two fixing plates 201 fit together and the grooves 2011 completely overlap. Then, the screw 202 is rotated to position the screw 202 between the two grooves 2011. Finally, the screw sleeve 203 is tightened to clamp the two fixing plates 201. In this way, the three first templates 1 can be combined into a complete cylinder.

[0039] In one embodiment of this utility model, such as Figure 2 As shown, each set of second locking mechanisms 5 includes two second end plates 501, multiple bolts 502 and multiple nuts 503.

[0040] Two second end plates 501 are respectively set on the two short sides of the corresponding second template 4 and overlap with the corresponding first end plate 101. Multiple bolts 502 pass through the corresponding first end plate 101 and second end plate 501 respectively, and multiple nuts 503 are respectively connected to the corresponding bolts 502.

[0041] It should be noted that the bolt 502 described in this embodiment is provided with a second handle to facilitate manual tightening by relevant personnel, and multiple overlapping through holes are respectively opened on the first end plate 101 and the second end plate 501.

[0042] Specifically, when it is necessary to produce a conical cement pole, the corresponding second template 4 is attached to the inner wall of the corresponding first template 1, and the second end plate 501 is completely overlapped with the first end plate 101. Then, the bolt 502 is passed through the corresponding through hole and locked with the nut 503 to keep the second template 4 stable. Finally, the first template 1 is connected together through the first locking mechanism 2, so that the inner curved surface of the second template 4 is combined to form a conical cavity, thereby producing a conical cement pole by centrifugal molding.

[0043] In one embodiment of this utility model, such as Figure 1 As shown, each first template 1 has a rib plate 102 on its outer curved surface.

[0044] Understandably, the rib plate 102 significantly improves the rigidity and bending strength of the first template 1, prevents deformation, and extends its service life.

[0045] In summary, the cement pole mold of this utility model has a cylindrical body composed of multiple first templates. During demolding, by disassembling two of the first templates, the remaining first template covers less than half of the cement pole's surface area. This allows the cement pole to be directly clamped by a lifting clamp for demolding, saving time and effort, improving work efficiency, and reducing the risk of damage to the cement pole.
