Description

A hoisting structure for a comprehensive distribution box

technical field

The utility model belongs to the field of distribution boxes, in particular to a lifting structure for a comprehensive distribution box.

Background technique

The typical design scheme of the State Grid Corporation of the existing JP cabinet: the JP cabinet is fixed under the transformer and connected by channel steel, but there are defects: 1. One side of the channel steel is fixed on the box body, and bolts, elastic washers, flat washers, sealing rings, etc. are used to fix the JP cabinet. The series of parts are fastened. Due to hanging for many years, the force point is on the top, and the top of the box is slowly deformed under the force. The sealing ring is easy to age due to sun and rain. Water enters the top. The protection level does not meet the requirements of outdoor products, resulting in corrosion of live equipment. , the performance of insulating parts is reduced, affecting the quality of power supply, and burying potential safety hazards for the normal operation of the power supply system; 2. In addition, the channel steel has been exposed outdoors for a long time and needs to be hot-dip galvanized. Electroplating is a heavy polluting enterprise, causing damage to the natural environment; 3 1. The processing of channel steel holes is completed on the bench drill, which not only greatly increases the efficiency and low cost for the manufacturer, but also has a long cycle for external processing of channel steel, which seriously restricts the delivery time.

Contents of the invention

Aiming at the deficiencies in the prior art, the utility model provides a lifting structure for a comprehensive distribution box to solve the problem of lifting the existing channel steel, long-term use, easy aging of the sealing ring, water ingress at the top, long processing cycle of the channel steel, and pollution serious problem.

The utility model is realized through the following technical solutions.

A lifting structure for a comprehensive distribution box, comprising a distribution box, the distribution box is provided with a stainless steel plate, the stainless steel plate is bent into an L shape, and the bent stainless steel plate includes a horizontal part and a vertical part part, the vertical part is provided with a fixing hole, the side of the distribution box is provided with a matching hole, the horizontal part is provided with a lifting hole, and a lifting rod is arranged in the described lifting hole, and the lifting rod It includes bolts, elastic washers and flat washers, two round holes are opened on the vertical part, and the two sides of the stainless steel plate are welded to fix the triangular plate. The original sealing ring on the lifting rod disappears, and by setting it on the side of the distribution box, rainwater can be discharged from the gap between the distribution box and the stainless steel plate without water accumulation.

As a preference, the thickness of the stainless steel plate is 3mm. Good material, no need for galvanizing, long service life,

Preferably, the fixing hole and the matching hole are fixed by screwing together. It is firmly fixed. If channel steel is used, workers need to reach into it to install it, which is easy to scratch and slow in efficiency. However, if it is installed on the vertical part, the installation is simple and efficient.

Compared with the existing technology: less sealing rings, better drainage effect, no top welding angle steel, bent with 3mm stainless steel, corrosion-resistant, permanent and reliable lifting function.

Detailed ways

A lifting structure for a comprehensive distribution box, including a distribution box, on which a stainless steel plate 1 is arranged, the stainless steel plate 1 is bent into an L shape, and the bent stainless steel plate 1 includes a horizontal portion and the vertical portion, the vertical portion is provided with a fixing hole 3, the side of the distribution box is provided with a matching hole, the horizontal portion is provided with a lifting hole, and a lifting rod 5 is arranged in the lifting hole, The lifting rod 5 includes bolts, elastic washers and flat washers, two round holes 2 are provided on the vertical part, the two sides of the stainless steel plate 1 are welded and fixed with triangular plates 4, the stainless steel plate 1 The thickness is 3 millimeters, and the described fixing hole 3 and the matching hole are screwed and fixed by bolts.

The stainless steel lifting parts are bent with 3 mm stainless steel plate, the structural size is consistent with the channel steel, and the triangle plate 4 is welded on both ends to enhance the overall strength.

The stress point is moved from the top of the distribution box to both sides of the distribution box, and a series of parts such as bolts, elastic washers, flat washers, etc. are installed in the fixing holes 3, and the fastening is convenient.

The lifting rod 5 is fastened with a series of parts such as bolts, elastic washers, and flat washers, and the sealing ring is eliminated to save costs. Rainwater enters the gap between the lifting rod 5 and the stainless steel plate 1, and can be drained from the gap between the distribution box and the stainless steel plate 1. Slit drains so no seals are needed and no water can collect.

The vertical portion of the stainless steel plate 1 directly offers two 2 round holes 2 instead of the ring function, which is convenient for lifting.

The scope of protection of the present utility model includes but not limited to the above embodiments, the scope of protection of the present utility model is subject to the claims, and any replacement, deformation, and improvement that are easily thought of by those skilled in the art all fall within this specification. Protection scope of utility model.
