Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, in particular to a ring network box-type transformer substation which is convenient for hoisting. Background Art

[0002] Box-type substation, also called prefabricated substation or prefabricated substation, is a high-voltage switchgear, which replaces the original civil power distribution room and distribution station, integrates transformer step-down, low-voltage power distribution and other functions, and is installed in a movable steel structure box. It is suitable for urban network construction and transformation, and is widely used in mines, factories, enterprises, oil and gas fields and wind power stations. Box-type substation is suitable for residential areas, urban public substations, bustling downtown areas, construction power supplies, etc. Users can choose box-type transformers according to different usage conditions and load levels.

[0003] At present, when transferring a box-type substation, in order to improve the efficiency of its transfer and reduce tedious steps such as disassembly and assembly, the box-type substation is usually transferred by an overall lifting method. The traditional lifting method is to use a lifting rope to connect the hooks at the four corners of the bottom of the box-type substation, and connect the lifting equipment at its end, and lift the box-type substation through the lifting equipment. However, due to the uneven internal mass distribution of the box-type substation, that is, its center of gravity is not in the center, which causes the box-type substation to tilt easily during lifting. When tilting, the hooks at the four corners of the bottom of the box-type substation and the lifting ropes have relative friction and sliding, and there is a safety hazard that the lifting ropes are detached from the hooks, which further affects the stability of the lifting process. In view of this, we propose a ring network box-type substation that is easy to lift. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a ring network box-type substation that is easy to hoist, so as to solve the technical problem that the current box-type substation is prone to tilt during the hoisting process, affecting the hoisting stability.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a ring network box-type substation that is easy to hoist, including a box-type substation cabinet with two sets of hoisting mechanisms on both sides;

[0006] The top of the box-type substation cabinet is equidistantly and detachably provided with a cover;

[0007] The hoisting mechanism includes a connecting rod 1 fixedly arranged at the center position of the end of one side of the box-type substation cabinet, a connecting rod 2 fixedly arranged on one side of the box-type substation cabinet, and a connecting rod 3 detachably arranged on one side of the cover body, and the ends of the connecting rod 3, the connecting rod 2 and the connecting rod 1 away from the box-type substation cabinet are respectively connected to the limiting plate 3, the limiting plate 2 and the limiting plate 1;

[0008] The bottom of both sides of the box-type substation cabinet are symmetrically fixed with receiving components, and a sling assembly for lifting the box-type substation cabinet is arranged around the receiving component, connecting rod one, connecting rod two and connecting rod three, and one end of the sling assembly is detachably connected to the receiving component.

[0009] Preferably, the receiving component includes a hanging rod with a baffle at one end away from the box-type substation cabinet, and an annular plate is arranged at the end of the hanging rod whose outer edge faces the baffle, and a groove for the end of the sling assembly to extend into and hook is formed between the baffle and the annular plate, and an arc-shaped anti-slip rod is arranged in a circular array at the outer edge of one side of the annular plate facing the baffle, and the arc-shaped anti-slip rod is an arc-shaped rod-shaped structure with one end bent toward the baffle.

[0010] Preferably, the sling assembly comprises a sling body, one end of which is fixedly connected with a hook, and the hook is detachably hooked on the outer edge surface of the hanging rod between the trough bodies.

[0011] Preferably, the sling body is arranged in a circuitous manner on the outer edge surfaces of connecting rod one, connecting rod two and connecting rod three, and the sling body forms bending part one, bending part two and bending part three at the connecting rod one, connecting rod two and connecting rod three respectively.

[0012] Preferably, both bottom sides of the box-type substation cabinet are detachably provided with cover plates, and both sides of the bottom of the box-type substation cabinet are symmetrically provided with rectangular plates.

[0013] Preferably, one end of the hanging rod away from the baffle extends out of the rectangular plate and is connected to a fixing plate, through holes are symmetrically provided in the cover plate, and one end of the hanging rod away from the fixing plate extends out of the through holes.

[0014] Preferably, a connecting plate for fixing the cover bodies is detachably installed between two adjacent cover bodies, cabinet doors are movably provided on both sides of the box-type substation cabinet, and ventilation grooves are arranged in an array inside the cabinet doors for ventilation and heat dissipation.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. By arranging a lifting mechanism and a sling assembly on both sides of the box-type substation cabinet, during the lifting process of the box-type substation cabinet, the end of the sling assembly is subjected to force and drives the box-type substation cabinet to be lifted as a whole. During the lifting process, multiple force points are formed at the winding places of the connecting rod 1, the connecting rod 2 and the connecting rod 3 with the help of the sling assembly. Because the lifting mechanism is respectively provided with two groups on both sides of the box-type substation cabinet, it will establish pulling points at the four corners of the bottom of the box-type substation cabinet during the lifting process. When the box-type substation cabinet is tilted, a force opposite to the tilt direction of the box-type substation cabinet is formed between the multiple force points, thereby limiting and hindering the tilt of the box-type substation cabinet, and avoiding a large tilt of the box-type substation cabinet during the lifting process, which affects the stability of the lifting process.

[0017] 2. By setting an arc-shaped anti-drop rod on one side of the annular plate, after the hook is hooked to the hanging rod for connection, the sling body is in a taut state during the lifting process. When the box-type substation cabinet tilts after lifting, the arc-shaped anti-drop rod can prevent the hook from falling off, thereby reducing the potential safety hazard of the hook sliding and falling off due to the tilt of the box-type substation cabinet, which is conducive to ensuring the stability of the lifting process.
