TECHNICAL FIELD
[0001] The utility model belongs to concrete pole production technical field, concretely relates to a concrete pole leakproof slurry mould. BACKGROUND
[0002] Concrete pole is an important power infrastructure, and is widely used in power transmission line, communication line and other fields. In the production process of concrete pole, the mould is one of the key equipment.
[0003] The existing concrete pole mould is usually composed of two half-circular shells to form a hollow cylindrical structure. Since there will be a gap between the contact surfaces of the mould after closing, the concrete slurry inside the mould is easy to splash out of the gap during centrifugal rotation of the pole mould, resulting in loss of water in the concrete, which in turn reduces the solidification effect of the concrete and affects the quality and performance of the entire pole. In addition, if the gland at both ends of the mould is not fixed firmly, the slurry leakage will occur, which not only causes waste of raw materials, but also pollutes the production environment. SUMMARY
[0004] In order to overcome the problem that the existing concrete pole mould has a gap between the contact surfaces after closing, the concrete slurry inside the mould is easy to splash out of the gap during centrifugal rotation of the pole mould, resulting in loss of water in the concrete, which in turn reduces the solidification effect of the concrete and affects the quality and performance of the entire pole, and in addition, if the gland at both ends of the mould is not fixed firmly, the slurry leakage will occur, which not only causes waste of raw materials, but also pollutes the production environment, the utility model provides a concrete pole leakproof slurry mould. By setting an arc-shaped slot on the inner wall of the upper mould and an arc-shaped protrusion on the inner wall of the lower mould, which are mutually engaged with the arc-shaped slot, the connection between the upper mould and the lower mould is more tight. At the same time, tooth-shaped connecting blocks are arranged at the opening ends of the upper mould and the lower mould, which are mutually engaged to form a labyrinth seal structure, reducing the gap between the contact surfaces of the mould and preventing the slurry leakage, ensuring the solidification effect of the concrete and improving the quality and performance of the pole. The gland is sealingly connected with the end portions of the upper mould and the lower mould under the elastic force of the elastic connecting member, ensuring the sealing effect of the mould at both ends and avoiding the slurry leakage caused by the insecure fixing of the gland, thereby reducing the waste of raw materials and the pollution to the production environment.

The upper mold and the lower mold are fixedly connected by connectors to form a hollow cylindrical structure. The pressure cap is installed at the ends of the upper mold and the lower mold through elastic connectors.
[0006] Both the upper and lower mold ends are provided with a fixing plate, and the fixing plate is provided with positioning holes evenly arranged along the circumferential direction. The end face of the pressure cap is provided with a cylindrical top block extending into the interior of the upper and lower molds. The diameter of the cylindrical top block is smaller than the inner diameter of the upper and lower molds. An annular groove is provided on one side of the cylindrical top block on the pressure cap, and an annular sealing gasket that contacts the fixing plate is embedded in the annular groove.
[0007] The elastic connector includes fastening bolts and springs. The pressure cover has through holes evenly opened along the circumferential direction, corresponding to the positioning holes on the fixed plate.

The toothed connecting block of the lower mold has multiple sets of mounting blocks at equal intervals along the longitudinal direction. The mounting blocks are located at the U-shaped slots and are hinged with bolts that can rotate up and down.

[0010] The beneficial effects of this utility model are:
[0011] This invention features an arc-shaped groove on the inner wall of the upper mold and an arc-shaped protrusion on the inner wall of the lower mold that engages with the groove, resulting in a tighter connection between the upper and lower molds. Simultaneously, interlocking toothed connecting blocks at the opening ends of the upper and lower molds form a labyrinthine sealing structure, reducing gaps between the mold contact surfaces, preventing grout leakage, and ensuring the concrete's setting effect, thereby improving the quality and performance of the utility pole.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0020] This utility model discloses a concrete pole anti-leakage mold, which mainly includes an upper mold 1, a lower mold 2, a pressure cap 3, and an elastic connector 4. The upper mold 1 has two sets of arc-shaped grooves 101 on its inner wall, and the lower mold 2 has arc-shaped protrusions 201 on its inner wall that engage with the arc-shaped grooves 101. The opening ends of the upper mold 1 and the lower mold 2 are provided with toothed connecting blocks 102, which engage with each other to form a labyrinth-like sealing structure. The upper mold 1 and the lower mold 2 are fixedly connected by the connector to form a hollow cylindrical structure. The pressure cap 3 is installed at the ends of the upper mold 1 and the lower mold 2 through the elastic connector 4.
[0021] First, the reinforcing cage is placed inside the lower mold 2. Then, the mold is closed to align the upper mold 1 and the lower mold 2. The interlocking of the arc-shaped protrusion 201 and the arc-shaped groove 101, as well as the interlocking of the toothed connecting block 102, ensures a tight connection between the upper mold 1 and the lower mold 2, effectively reducing gaps between the mold contact surfaces and preventing concrete slurry from splashing out of the gaps. Next, the upper mold 1 and the lower mold 2 are fixedly connected together by connectors to form a stable hollow cylindrical structure. Then, concrete slurry is injected into the mold to fill the cavity. Finally, the pressure cap 3 is installed at the ends of the upper mold 1 and the lower mold 2 using elastic connectors 4, so that the pressure cap 3 presses against the mold ends, thereby providing a good sealing effect, preventing slurry leakage during the centrifugation process, enhancing the tightness of the connection, ensuring the sealing effect, thereby improving the quality and performance of the concrete pole, while reducing the waste of raw materials and pollution to the production environment. After the concrete has been centrifuged and solidified, the operator removes the connectors and pressure cap 3, separates the upper mold 1 and the lower mold 2, and then takes out the formed concrete pole.
[0022] Both the upper mold 1 and the lower mold 2 are provided with a fixing plate 103 at their ends. Positioning holes are evenly distributed along the circumference of the fixing plate 103. A cylindrical top block 301 extending into the interior of the upper mold 1 and the lower mold 2 is provided on the end face of the pressure cap 3. The diameter of the cylindrical top block 301 is smaller than the inner diameter of the upper mold 1 and the lower mold 2. An annular groove 302 is provided on one side of the cylindrical top block 301 on the pressure cap 3. An annular sealing gasket 303 that contacts the fixing plate 103 is embedded in the annular groove 302. The elastic connecting member 4 includes a fastening bolt 401 and a spring 402. The pressure cap 3... The upper circumference is uniformly provided with through holes corresponding to the positioning holes on the fixed plate 103. The pressure cap 3 is connected to the fixed plate 103 of the upper mold 1 and the lower mold 2 by fastening bolts 401. A spring 402 is fitted on the fastening bolt 401 and abuts against the side end face of the fixed plate 103. Under the elastic force of the spring 402, the pressure cap 3 and the annular sealing gasket 303 are always in contact with and pressed against the end face of the fixed plate 103, ensuring the sealing effect at both ends of the mold and avoiding the leakage problem caused by the pressure cap 3 not being fixed firmly, thereby reducing the waste of raw materials and the pollution to the production environment.
[0023] The toothed connecting block 102 has multiple sets of U-shaped slots 1021 equidistantly provided on it. The toothed connecting block 102 of the lower mold 2 has multiple sets of mounting blocks 1022 equidistantly provided along the longitudinal direction. The mounting blocks 1022 are located at the U-shaped slots 1021. The mounting blocks 1022 are hinged with bolts 1023 that can rotate up and down. After the operator rotates the bolts 1023 into the U-shaped slots 1021, he tightens the bolts 1023 so that the upper mold 1 and the lower mold 2 are fixedly connected to form a complete and stable mold.
[0024] The outer walls of the upper mold 1 and the lower mold 2 are provided with multiple sets of parallel reinforcing ribs 104 at equal intervals along the circumferential direction. The outer walls of the upper mold 1 and the lower mold 2 are also provided with multiple sets of reinforcing rings 105 at equal intervals along the axial direction, which are perpendicularly connected to the reinforcing ribs 104. This can increase the bending and torsional resistance of the mold, making it more stable during use, reducing the risk of deformation and damage, and thus extending the service life of the mold.
[0025] Work process:
[0026] First, the reinforcing cage is placed inside the lower mold 2. Then, the mold is closed to align the upper mold 1 and the lower mold 2. The interlocking of the arc-shaped protrusion 201 and the arc-shaped groove 101, as well as the interlocking of the toothed connecting block 102, ensures a tight connection between the upper mold 1 and the lower mold 2, effectively reducing gaps between the mold contact surfaces and preventing concrete slurry from splashing out of the gaps. Next, the upper mold 1 and the lower mold 2 are fixedly connected together by connectors to form a stable hollow cylindrical structure. Then, concrete slurry is injected into the mold to fill the cavity. Finally, the pressure cap 3 is installed at the ends of the upper mold 1 and the lower mold 2 using elastic connectors 4, so that the pressure cap 3 presses against the mold ends, thereby providing a good sealing effect, preventing slurry leakage during the centrifugation process, enhancing the tightness of the connection, ensuring the sealing effect, thereby improving the quality and performance of the concrete pole, while reducing the waste of raw materials and pollution to the production environment. After the concrete has been centrifuged and solidified, the operator removes the connectors and pressure cap 3, separates the upper mold 1 and the lower mold 2, and then takes out the formed concrete pole.
