[0002] Centerline lights are a type of airport ground lighting equipment, that is, lighting equipment that indicates the centerline position of the airport runway. It consists of a sealed base, a light source, a lens, and a high-intensity lamp cover. The device is buried underground but several millimeters above the ground. At night or in poor visibility, it enables aircraft to take off, land, and taxi at the correct position on the runway and taxiway.

[0003] During the construction of the navigation lighting project, the centerline lights will be installed. At present, there are many construction methods for installing the centerline lights: the first is the drilling construction method, that is, drilling a light pit on the hardened road surface with a drilling device. The light pit obtained by drilling construction has a good molding effect, but the equipment investment is large, the cost is high, and it consumes manpower. Usually, the second reserved pit construction method is adopted, and the light mold is installed during the pouring of concrete. That is, through the cushioning effect of the poured concrete, the light mold is installed to the appropriate position of the secondary piping of the lamp, which has the disadvantages of inconvenient construction and not conducive to checking the elevation. Since the light mold is a metal product, it needs to be removed before the concrete is completely solidified. The concrete that has not been completely solidified is not only easy to adhere to the light mold during the demoulding process, but also burrs are easy to appear on the inner wall of the molded light pit. During demoulding, it is also easy to cause the light pit to deform and the quality of the light pit molding is poor. Summary of the invention

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0035] As shown in the accompanying drawings, the shallow barrel lamp mold includes a mold body and a locking device 5; the mold body is a cylindrical structure with openings at both ends, and has a lamp body space section 3 and a piping space section 4 that are connected; the inner diameter of the lamp body space section 3 is larger than the inner diameter of the piping space section 4; the mold body includes an inner cylinder 1 and an outer cylinder 2; the outer cylinder 2 is made of elastic material and is sleeved outside the inner cylinder 1; the inner side wall of the inner cylinder 1 is provided with a limit member 101, and the limit member 101 is located in the lamp body space section 3; the locking device 5 includes a plurality of The connecting part 501, the first locking part 502 and the second locking part 503 are arranged coaxially; the first locking part 502 and the second locking part 503 are both located in the piping space section 4, and the first locking part 502 is clamped with the inner cylinder 1; the distance from the outer side surface of the first locking part 502 to the axis L of the piping space section 4 is greater than the distance from the outer side surface of the second locking part 503 to the axis L of the piping space section 4; the connecting part 501 is located in the lamp body space section 3.

[0036] The template encloses a casting space, and the secondary piping 6 of the lamp is pre-placed in the casting space. The secondary piping 6 of the lamp is bent into an L shape and has a vertically arranged connecting section 601. The inner diameter of the piping space section 4 is greater than or equal to the outer diameter of the connecting section 601, so that the connecting section 601 can be installed in the piping space section 4. The connecting section 601 is installed in the piping space section 4 so that the pipe mouth of the connecting section 601 is located in the axial middle of the piping space section 4. That is, the installation position of the first locking part 502 is reserved above the connecting section 601. At this time, the lamp body space section 3 and the piping space section 4 are arranged up and down. Then the locking device 5 is installed, the second locking part 503 extends into the connecting section 601 and is clamped therewith, and the first locking part 502 is clamped with the inner cylinder 1. Before pouring concrete, the mold body, the locking device 5 and the connecting section 601 are connected, which is convenient for construction and conducive to checking the elevation. The lower end surface of the first locking portion 502 contacts the pipe opening of the connecting section 601, and the first locking portion 502 limits the connecting section 601 axially from above, and prevents the mold body from floating up along the axis L when pouring and vibrating concrete. The second locking portion 503 limits the connecting section 601 radially, and prevents the mold body from deviating from the axis L when pouring and vibrating concrete. The first locking portion 502 and the second locking portion 503 work together, and the locking effect is good.

[0037] The inner cylinder 1 can be a cast iron product, and the inner cylinder 1 is preferably a steel product. Preferably, the outer cylinder 2 is a rubber product, which can be a silicone product. As a further preference, the outer cylinder 2 is a rubber product. The outer cylinder 2 is sleeved outside the inner cylinder 1, and is installed with the inner cylinder 1 by its own elastic deformation and contraction. After the concrete is completely solidified, the locking device 5 is first taken out. Then, through the cooperation of the puller and the limit part 101, it is lifted upward to take out the mold body. When the locking device 5 and the mold body are removed, the concrete has been completely solidified, and the inner wall of the lamp pit after molding has no obvious burrs and is not easy to deform. The outer cylinder 2 of the rubber product has poor adhesion to the solidified concrete, which is conducive to the removal of the mold body. The first locking part 502 and the second locking part 503 of the locking device 5 work together to accurately align the molded lamp pit with the connecting section 601. It has the advantages of convenient demolding and good molding quality of the lamp pit after demolding.

[0038] The connecting portion 501, the first locking portion 502 and the second locking portion 503 can be set as an integral structure or an integrally formed structure, in order to achieve detachable installation. Preferably, it also includes a mounting bolt 504; the first locking portion 502 and the second locking portion 503 are both installed by the mounting bolt 504, and the nut of the mounting bolt 504 serves as the connecting portion 501. The mounting bolt 504 realizes the detachable connection between the first locking portion 502 and the second locking portion 503.

[0039] The structure of the first locking portion 502 and the second locking portion 503 has a variety of specific implementations, and it is only necessary to ensure that the first locking portion 502 is clamped with the inner cylinder 1, and the second locking portion 503 is clamped with the connecting section 601. The first locking portion 502 and the second locking portion 503 can both be spiral structures. Preferably, the first locking portion 502 and the second locking portion 503 are both annular structures. The first locking portion 502 is in surface contact with the inner cylinder 1, which is conducive to the stable installation of the first locking portion 502 in the inner cylinder 1; the second locking portion 503 is in surface contact with the connecting section 601, and the second locking portion 503 is stably installed in the connecting section 601.

[0040] Preferably, the first locking portion 502 and the second locking portion 503 are both made of rubber products. Rubber products have a certain elastic deformation, are easy to install, and are tightly connected.

[0041] The stopper 101 can be a hanging ear, at least two hanging ears are evenly spaced and installed on the inner wall of the inner cylinder 1 along the circumferential direction, and the puller is connected to the hanging ear. After the concrete is completely solidified, the mold body is taken out upward. Preferably, the stopper 101 is a ring plate, and is installed at one end of the lamp body space section 3 away from the pipe space section 4. The ring plate cooperates with the puller, and after the concrete is completely solidified, the mold body is taken out upward.

[0042] The outer cylinder 2 and the inner cylinder 1 can be taken out at the same time. Preferably, a lubricating layer is provided between the outer cylinder 2 and the inner cylinder 1. The lubricating layer is composed of a lubricant, that is, the lubricant is applied between the outer cylinder 2 and the inner cylinder 1. When the inner cylinder 1 is taken out by the puller, the friction between the outer cylinder 2 and the inner cylinder 1 is reduced, which is conducive to the rapid separation of the outer cylinder 2 and the inner cylinder 1. After the inner cylinder 1 is taken out, the outer cylinder 2 loses support and further shrinks, and automatically separates from the concrete.

[0043] Preferably, the first gasket 505 and the second gasket 506 are further included; the first gasket 505 is installed between the nut of the mounting bolt 504 and the first locking portion 502; the second gasket 506 is installed between the head of the mounting bolt 504 and the second locking portion 503. Preferably, both the first gasket 505 and the second gasket 506 are metal gaskets, which is conducive to the stable installation of the first locking portion 502 and the second locking portion 503 on the mounting bolt 504.

[0044] Preferably, the lamp body space section 3 and the pipe space section 4 are coaxially arranged cylindrical structures.

[0045] A method for forming a lamp pit using a shallow barrel lamp mold is also provided, comprising the following steps:

[0046] Step A: install the connecting section 601 of the secondary pipe 6 of the lamp in the pipe space section 4 so that the pipe opening of the connecting section 601 is located in the middle of the pipe space section 4 in the axial direction.

[0047] The secondary pipe 6 of the lamp is installed in the casting space to form a bent L-shaped structure with a vertically arranged connecting section 601. The connecting section 601 is installed in the pipe space section 4. At this time, the lamp body space section 3 and the pipe space section 4 are arranged up and down. The installation position of the first locking part 502 is reserved above the connecting section 601, that is, the pipe opening of the connecting section 601 is located in the middle of the axial direction of the pipe space section 4.

[0048] Step B, insert the locking device 5 into the piping space section 4; the connecting portion 501 of the locking device 5 is located in the lamp body space section 3; the first locking portion 502 of the locking device 5 is engaged with the inner cylinder 1 and limits the position above the pipe opening of the connecting section 601; the second locking portion 503 is engaged in the connecting section 601.

[0049] The connecting portion 501 is located in the space section 3 of the lamp body, which is convenient for taking out the locking device 5. The first locking portion 502 limits the upper position of the connecting section 601 to prevent the mold body from floating along the axis L when pouring and vibrating concrete. Before pouring concrete, the mold body, the locking device 5 and the connecting section 601 are connected, which is convenient for construction and conducive to checking the elevation. The second locking portion 503 limits the radial position of the connecting section 601 to prevent the mold body from deviating from the axis L when pouring and vibrating concrete. The first locking portion 502 and the second locking portion 503 work together to achieve a good locking effect.

[0050] Step C, pouring concrete in the pouring space, and after the concrete is completely solidified, taking out the locking device 5 and then taking out the mold body.

[0051] Demolding begins 24 hours after concrete pouring is completed. At this time, the concrete has completely solidified, making it convenient for operators to operate on the pavement. First, remove the locking device 5, and then pull the inner cylinder 1 upward through the cooperation of the puller and the limiter 101 until the mold body is separated from the concrete.

[0052] The above is a specific implementation method of the present invention. It can be seen from the implementation process that the present invention provides a shallow barrel lamp mold that can improve the molding quality of the lamp pit. Compared with the background technology, before pouring concrete, the mold body, the locking device and the connecting section of the secondary piping of the lamp are connected, which is convenient for construction and conducive to checking the elevation. When the mold body and the locking device are removed, the concrete has been completely solidified, and there are no obvious burrs on the inner wall of the lamp pit after molding. The first locking part and the second locking part of the locking device work together to accurately align the molded lamp pit with the connecting section and are not easy to deform. It has the advantages of saving manpower and mechanical equipment costs, easy demolding, and good molding quality of the lamp pit after demolding. A lamp pit molding method is also provided.
