Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pole production, and in particular relates to a slurry leakage-proof concrete pole mould. Background Art

[0002] Utility poles are a crucial component of urban power construction and a crucial component of overhead distribution lines. They are primarily used to install crossarms, insulators, and conductors. Poles are categorized by material: wooden, metal, and concrete. Wooden poles are susceptible to weather and have a short service life, while metal poles are expensive to construct. Consequently, concrete poles are becoming increasingly popular.

[0003] The manufacturing process of concrete poles is as follows: the mold is composed of two hollow semi-cylinders combined into a cylindrical structure. The prepared pole steel skeleton is placed in one of the hollow semi-cylinders of the pole mold. Concrete is then poured into the hollow semi-cylinder of the pole mold. After the concrete is poured, the other hollow semi-cylinder is screwed together with the first hollow semi-cylinder through screw holes and bolts. The entire pole mold is then hoisted and rotated at high speed, making the concrete in the pole mold more compact and evenly filling the concrete in every part of the pole mold. Since the mold is divided into two parts to facilitate filling with concrete, and then the two parts are put together after the concrete is poured, there is a problem when the mold is centrifuged. Because there is always a gap between the two parts of the pole mold, the concrete slurry is easily splashed out of the gap during centrifugal rotation. This can easily lead to the loss of some water in the concrete, affecting the concrete solidification effect, and thus affecting the quality and performance of the entire pole. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a leakage-proof concrete pole mold. The present invention uses multiple sealing means to seal the gap between the two sets of semi-cylindrical molds after they are closed, thereby reducing the chance of leakage to a certain extent, or even completely preventing leakage.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A leak-proof concrete pole mold, comprising:

[0007] A semi-cylindrical mold, wherein two sets of semi-cylindrical molds are combined to form a complete hollow cylindrical structure, with wing plates fixedly connected to both sides of the semi-cylindrical mold. A space is left between the two wing plates on the same side of the semi-cylindrical mold after the two sets of molds are combined, and a connecting piece and an arc-shaped blocking strip are provided in the space. A plurality of first bolts are commonly passed through the two sets of wing plates and the connecting piece on the same side, a first nut is threadedly connected to the first bolt, and a plurality of second bolts are threadedly connected to the connecting piece, and the second bolts press against the arc-shaped blocking strip to block the gap after the two sets of semi-cylindrical molds are combined;

[0008] The inner ends of the semi-cylindrical mold are fixedly connected with semi-circular arc baffles, and the outer side of the baffle is fixedly connected with a plurality of threaded columns;

[0009] End covers are located on both sides of the two groups of semi-cylindrical molds, and the threaded column passes through the end covers and is threadedly connected to a second nut.

[0010] The above technical solution, its principle and technical effects:

[0011] The steel bar skeleton is placed in a complete hollow cylinder formed by the two sets of semi-cylindrical molds, and a connecting piece and an arc-shaped sealing strip are installed between the two wing plates on the same side of the semi-cylindrical mold after the two molds are combined. The first bolt passes through the wing plate, the connecting piece and the wing plate and is tightened with the first nut in sequence to fasten the semi-cylindrical molds of the two combined molds together. The gap after the two sets of semi-cylindrical molds are combined is sealed by tightening the second bolt to press the arc-shaped sealing strip. In this way, the probability of concrete slurry flowing out of the gap can be reduced. At the same time, one of the end covers is passed through the threaded column and tightened with the second nut, so that the end cover and the baffle are tightly fitted, reducing the probability of concrete slurry flowing out of the end gap. Concrete slurry can be put in from the other end, and then the end cover at the other end is tightened.

[0012] In a preferred example, the present invention can be further configured as follows: a first sealing gasket is provided at the joint of the two groups of semi-cylindrical molds.

[0013] In a preferred example, the present invention can be further configured as follows: a second sealing gasket is provided between the arc-shaped sealing strip and the semi-cylindrical mold.

[0014] In a preferred example, the present invention can be further configured as follows: a third sealing gasket is provided between the two groups of semicircular arc-shaped baffles at the same end after the mold is closed.

[0015] In a preferred example, the present invention can be further configured as follows: the first sealing gasket and the third sealing gasket are integrated into one body.

[0016] In a preferred example, the present invention can be further configured as follows: a fourth sealing gasket is provided between the end cover and the semicircular arc baffle.

[0017] In a preferred example, the present invention can be further configured as follows: semi-circular arc reinforcing plates are fixedly connected to both ends of the outer side of the semi-cylindrical mold, and reinforcing ribs are fixedly connected between the two semi-circular arc reinforcing plates on the same semi-cylindrical mold.

[0018] In a preferred example, the present invention can be further configured as follows: the outer end of the end cover is fixedly connected to an end plate with a diameter larger than the end cover, a gap is left between the end plate and the semicircular reinforcement plate, and a fifth gasket is provided in the gap.

[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0020] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0021] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0022] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0023] A threaded connection refers to a detachable connection in which the connected parts are connected together using a threaded part (or the threaded part of the connected parts).

[0024] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0025] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] Beneficial effects of the utility model:

[0027] The present application uses multiple sealing means to seal the gap between the two sets of semi-cylindrical molds after the molds are closed, thereby reducing the chance of slurry leakage to a certain extent, or even completely preventing leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] like Figure 1-5 As shown, a leak-proof concrete pole mold includes:

[0038] A semi-cylindrical mold 1, two groups of semi-cylindrical molds 1 are combined to form a complete hollow cylindrical structure, with wing plates 2 fixedly connected to both sides of the semi-cylindrical mold 1.
