Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a box-type transformer substation which is easy to hoist. Background Art

[0002] A box-type substation, also known as a prefabricated substation or prefabricated substation, is a type of high-voltage switchgear, distribution transformer and low-voltage distribution device.

[0003] At present, when a box-type substation is installed, it first needs to be hoisted onto a vehicle by a crane, and then transported to a designated location. For example, the publication (announcement) number: CN215772080U discloses a box-type substation that is easy to hoist, including a box-type substation body. A hoisting mechanism is provided on the top of the box-type substation body. Two external mounting grooves are provided on the front and back of the top of the box-type substation body. A group of guide wheels that cooperate with each other are symmetrically provided inside the external mounting groove. A base is fixedly installed on the bottom of the box-type substation body, and two groups of hook machines are provided on the front and back of the base.

[0004] In the above solution, the box-type substation is hoisted by a lifting rope. Although it can achieve a smooth hoisting, the box-type substation is exposed to the outside and there are many external obstacles during the hoisting process. It is easy for obstacles to come into contact with the surface of the box-type substation and cause damage or even destroy it. Therefore, a box-type substation that is easy to hoist is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the background technology and to provide a box-type substation that is easy to hoist.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, a hanging plate is fixedly provided on one end of the hanging cloth located outside the base, and a hanging hole is opened in the middle of the side surface of the hanging plate.

[0009] Preferably, the lifting cloth is woven from synthetic fiber yarns.

[0010] Preferably, a support plate is fixedly provided on the top of the substation body, and an anti-extrusion rubber pad is fixedly provided on the upper surface of the support plate.

[0011] Preferably, the four hoisting cloths can extend upward to above the support plate and cover the substation body.

[0012] Preferably, the size of the hanging plate is larger than the size of the opening of the base side wall.

[0013] Compared with the existing technology, the present invention provides a box-type substation that is easy to hoist and has the following beneficial effects:

[0014] 1. The box-type substation that is easy to hoist is equipped with a winding roller, a fixing block, a torsion spring and a lifting cloth. When the substation body needs to be hoisted, one end of the lifting cloth is manually pulled outward to release the lifting cloth from the winding roller until the lifting cloth extends to the top of the substation body. Then, the upper ends of the four lifting cloths are connected to the lifting ropes, so that the substation body can be hoisted. The substation body is located inside the four lifting cloths, which can play a protective role and prevent the surface of the substation body from being scratched or even damaged by obstacles.

[0015] 2. The box-type substation is easy to hoist. The hoisting plate is provided. The hoisting holes on the hoisting plate can be connected to the hoisting rope, so that the hoisting cloth can be opened and hoisted, thereby improving the protection effect of the substation body.

[0016] 3. The box-type substation, which is easy to hoist, is equipped with a support plate and an anti-extrusion rubber pad. The hoisting cloth can be stretched out by the support plate during the hoisting process. At the same time, the anti-extrusion rubber pad can play a protective role to avoid the anti-extrusion rubber pad from being damaged due to excessive extrusion force.

[0017] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. The utility model adopts a lifting cloth protection structure, which can not only lift the box-type substation stably, but also protect the box-type substation to prevent the surface of the substation body from being scratched or even damaged by obstacles.
