Description

Power distribution cabinet frame structure and matching method

Technical Field

The invention relates to the technical field of cabinet frame structures of electrical equipment, in particular to a power distribution cabinet frame structure and a matching method.

Background

The sectional materials used in the low-voltage power distribution cabinet in China at present are mainly 8MF sectional materials and C sectional materials. The 8MF section bar is widely applied to GGD, GCS, XGB, direct current screens and relay protection screens. The 8MF section bar is produced by adopting round holes with the diameter of 9.2mm and arranging the round holes according to the modulus of 20mm through a cold bending process. And the connection of the section bar and the side cross beam is fixed by adopting M8X20 screws. The disadvantages of this profile are mainly three:

1. the positioning error of the side cross beam is larger and reaches 1.2mm.

2. Each side beam needs 4 sets of M8X20 screws, and the consumption of standard components is large.

3. The side beam is inconvenient to position and install, two persons are required to install the side beam in a matched mode, and labor cost is high.

Disclosure of Invention

In order to solve the problems of high standard component consumption and high cost in the prior art, the invention provides a power distribution cabinet frame structure and a matching method capable of saving cost.

The technical scheme adopted for solving the technical problems is as follows:

the utility model provides a switch board framework structure, includes stand and crossbeam, the stand on be equipped with the hanging hole, the crossbeam on be equipped with at least one and be used for hanging the hook on the lower limb of hanging hole.

Further, the stand include supporting part and installation department, installation department include first folded plate, second folded plate and third folded plate, first folded plate and third folded plate are located the both sides of second folded plate respectively, hanging hole on the stand is the square hole of setting at least on first folded plate.

Further, the first folded plate is perpendicular to the second folded plate, and the second folded plate is perpendicular to the third folded plate, so that the cross section of the mounting part is -shaped. The mounting portion of the present invention is structurally stronger than the prior L-shaped mounting portion.

Further, the crossbeam includes the main part, and the main part both ends have the mounting panel, the hook set up on the mounting panel, the hook is including setting up the first hook that is close to upper edge position at the mounting panel and setting up the second hook that is close to lower edge position at the mounting panel, first hook and second hook are located the same side of mounting panel.

Further, the height of the first hook is smaller than or equal to the height of the square hole at the corresponding position, the vertical distance between the first hook and the mounting plate and the vertical distance between the second hook and the mounting plate are equal to the thickness of the first folded plate, the height of the second hook is larger than the height of the square hole at the corresponding position, and the lower edge of the second hook exceeds the lower edge of the mounting plate.

Further, the width of the first hook is equal to the width of the corresponding square hole, and the width of the second hook is equal to the width of the corresponding square hole. Positioning is achieved across the width.

Further, the upright post is also provided with a first round hole, the mounting plate is provided with a second round hole corresponding to the first round hole, and the first round hole is connected with the second round hole through a screw.

Further, the first hook and the second hook are formed by stamping.

The matching method of the power distribution cabinet frame body structure comprises the following steps:

s1: firstly, the upper end of the cross beam is inclined towards the direction far away from the upright post, and then the second hook is inserted into the corresponding square hole;

s2: then the upper end of the cross beam is close to the upright post until the first hook is inserted into the corresponding square hole, and the cross beam is continuously leaned against the upright post;

s3: when the main body abuts against the upright post, the whole cross beam is pulled down until the first hook and the second hook are both hooked on the upright post;

s4: the first round hole and the second round hole are connected and positioned through screws.

Further, the height of the second hook is larger than that of the square hole at the corresponding position, so that the tail end of the second hook hooks the first folded plate at the lower end of the square hole at the corresponding position in the process that the first hook is inserted into the square hole at the corresponding position.

The beneficial effects are that:

(1) According to the invention, the hook is adopted for matching, so that the number of screws is reduced, each side beam needs 2M 6X12 self-tapping screws, the consumption of standard components is reduced by 89.4%, and the cost is reduced;

(2) The first folded plate is perpendicular to the second folded plate, and the second folded plate is perpendicular to the third folded plate, so that the cross section of the mounting part is -shaped. The mounting part of the invention has stronger structural strength than the prior L-shaped mounting part

(3) The vertical distance between the first hook and the mounting plate and the vertical distance between the second hook and the mounting plate are equal to the thickness of the first folding plate, so that the contact area is increased, the positioning accuracy is 0.2mm, and the positioning accuracy is improved;

(4) Firstly, positioning and matching are carried out through the hooks, and then the positioning of the side cross beam is fast and accurate through screw positioning and locking;

(5) The side cross beam is convenient to position and install, and can be completed by only one person, so that the labor cost is reduced;

(6) The second hook of the invention has a positioning and supporting function on one hand, and on the other hand, if the first hook and the second hook are not well positioned together, in the invention, the second hook is positioned first, the height of the second hook is slightly larger than the height of the corresponding square hole, thus, when the second hook is positioned, the second hook can enter the square hole only by tilting, and because the height of the second hook is slightly larger than the height of the square hole, the tail end of the second hook slightly hooks the edge of the square hole in the process that the cross beam returns to the vertical state, and the length of the tail end of the second hook hooked the edge of the square hole is longer when the second hook approaches to the vertical state, so that the second hook cannot be separated from the square hole, and the first hook can be safely installed, thereby being convenient to operate. The second hook is prevented from being separated again in the process of aligning the first hook, so that the installation process is prolonged.
