Description

Technical Field

[0001] The present invention belongs to the technical field of box-type substations, and in particular relates to a box-type substation that is easy to hoist. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban network construction and renovation. It is a new type of substation that has emerged after civil substations. During the installation process of a box-type substation, equipment such as loaders and cranes are required to transport the box-type substation to the installation site. The detailed construction steps are as follows:

[0003] First of all, before the box-type substation leaves the factory, the relevant equipment of the box-type substation needs to be inspected one by one. After the inspection, the box-type substation is transported to the installation site by a loader and prepared for lifting. Before lifting, the lifting equipment (gantry crane, crane, etc.) and tools (slings, wires, equipment steel frame structure) need to be safety checked. After the steel sections and fixed connection points on the top of the box-type substation are removed, the lifting ears on the top of the box-type substation are exposed. Four equal-length slings are used to reliably connect the crane hook to the lifting ears on the top of the box-type substation. Then the crane slowly lifts the hook. During the lifting process of the box-type substation, pay attention to keeping the box-type substation balanced and not shaking, check the safety of the slings and whether the force points are appropriate and whether the force is uniform, until the box-type substation is hoisted and stabilized at the installation site. The current box-type substation includes a box cover, a box body and lifting parts. The lifting parts are usually made of A separately provided auxiliary part, such as a lifting plate, is installed on the top of the box-type substation. A lifting lug is provided on the top of the lifting plate, and the four corners of the lifting plate are connected to the bottom of the box through lifting ropes or other connecting parts to ensure that the force point is located at the bottom of the box during the lifting process. This method has certain requirements for the installation position and fixing method of the lifting plate. For example, the lifting plate is required to be located directly above the top of the box. During the lifting process, the position of the lifting plate and the length of the rope need to be continuously adjusted. If the adjustment is wrong, the box-type substation will fall over and damage the equipment. Therefore, the stability is low. Moreover, the top of the box-type substation is either arched or flat. Therefore, the lifting plate does not have a uniform shape and has poor versatility. At the same time, after the lifting is completed, it needs to be dismantled and reinstalled each time it is moved. Therefore, there are problems such as troublesome debugging and installation, poor versatility and poor stability. Summary of the Invention

[0004] The technical problem solved by the present invention is to provide a box-type substation that is easy to hoist, so as to solve the problems of the box-type substation in the prior art that it is difficult to debug and install, has poor versatility and poor stability during hoisting.

[0005] The basic solution provided by the present invention is: a box-type substation that is easy to hoist, including a box body, a box cover and a hoisting piece, the box cover is fixedly connected to the top of the box body, the box body includes a base, several cross beams and several corner columns, the corner columns are vertically installed around the base, the top of the corner column is provided with a corner column mounting part, the corner column mounting part is provided with a corner column mounting hole, the cross beam is connected and fixed to the corner column mounting part through the corner column mounting hole; the hoisting piece includes a lifting iron, a lifting iron clamp and a lifting ear, the lifting iron is installed on the inner side of the corner column mounting part and the top of the lifting iron is against the bottom of the box cover, the lifting iron clamp fixes the lifting iron through the corner column mounting hole, the lifting ear passes through the top of the box cover and the bottom of the lifting ear is connected to the top of the lifting iron.

[0006] The principle and advantage of the present invention are that: in the hoisting process of the box-type substation in the prior art, a hoisting plate is usually installed on the top of the box-type substation, and the hoisting plate is connected and fixed to the bottom of the box body of the box-type substation through a connecting piece, so that when the box-type substation is hoisted, its force point is located on the box body, which is convenient for hoisting. However, during the hoisting process, it is necessary to constantly adjust the position of the hoisting plate and the length of the rope. If the adjustment is wrong, the box-type substation will fall over and damage the equipment. Therefore, the stability is low, and the top of the box-type substation is either arched or flat, so the hoisting plate does not have a uniform shape and has poor versatility. At the same time, after the hoisting is completed, it needs to be dismantled and reinstalled each time it is moved, so there are troubles in debugging and installation.

[0007] To solve the above problems, the present application provides a box-type substation that is easy to hoist, comprising a box body, a box cover, and a hoisting member. The box body is composed of a base, multiple crossbeams, and multiple corner posts. The corner posts are vertically mounted on the base. The tops of the corner posts are provided with corner post mounting portions, and the corner post mounting portions are provided with corner post mounting holes. The crossbeams are fixedly connected to each other and then to the corner posts, thereby forming the entire box body structure. The box cover is fixed to the top of the box body. The hoisting member includes a lifting lug, a lifting iron, and a lifting iron clamping plate. The lifting iron is located on the mounting surface of the corner post, and the lifting iron is fixed to the mounting surface by the lifting iron clamping plate. The lifting lug passes through the box cover and is exposed. At the same time, the bottom of the lifting lug is fixedly connected to the lifting iron.

[0008] When lifting the box-type substation, the hook of the crane is fixedly connected to the lifting ear exposed above the box cover. Under the connection action of the lifting iron, the force applied by the hook to the lifting ear is transmitted to the lifting iron, and the lifting iron is fixed to the corner column of the box body through the lifting iron clamping plate, and the corner column is fixedly connected to the base of the box body. Therefore, when lifting the box-type substation, force is applied to the box body. Compared with the prior art that uses the lifting ear to fix the top of the box cover for lifting, it can avoid the tension applied by the crane hook directly acting on the box cover, reducing the damage of the box cover during the lifting process. In addition, for the prior art that uses the lifting plate to be installed on the top of the box cover and fix the lifting plate to the base of the box body through connecting parts such as lifting ropes, it is first necessary to debug the stability of the lifting plate and the lifting rope to ensure that the box-type substation is balanced when the lifting plate is lifted. At the same time, the length of the lifting strap of the crane connecting the hook is also required Debugging is required to ensure that the box-type substation is in a stable state during hoisting. After the hoisting is completed, the hoisting plate and hoisting rope need to be disassembled and installed again next time. The hoisting iron provided in this application is fixed to the corner column of the box body through the hoisting iron clamp when the box-type substation is installed for the first time. It does not need to be disassembled subsequently and can be used directly each time it is hoisted. There is no need to frequently install and disassemble it during each move. At the same time, during the hoisting process, only the length of the sling connecting the crane hook needs to be debugged, so that the box-type substation is in a stable state during hoisting, and the hoisting iron is not affected by the top shape of the box cover of the box-type substation, and has strong versatility. At the same time, the hoisting iron is fixed on the corner column of the box body. The corner column serves as the supporting structure of the box body and has strong firmness. The pulling force during hoisting is applied to the corner column, so that it will not easily break or tip over during hoisting, and has strong stability.

[0009] Therefore, the advantage of the present application is that the hanging iron is fixed to the corner column by the hanging iron clamp, and the lifting ear passes through the box cover and is fixedly connected to the top of the hanging iron, so that during the lifting process, frequent debugging and disassembly and installation are not required. At the same time, the pulling force acts on the corner column of the box body during lifting, which makes the debugging and installation of the box-type substation simple during lifting. The hanging iron is fixed on the corner column and is not affected by the shape of the box cover, and has strong versatility. At the same time, the pulling force acts on the corner column, and it will not easily break or tip over, and has strong stability.

It is installed in a fully enclosed, movable steel structure box. During the process from the box-type substation leaving the factory to the installation, handling equipment and lifting equipment, such as transport vehicles and cranes, are required. During the lifting process, the existing technology often uses some lifting auxiliary tools, such as lifting plates or lifting clamps.
