Switch cubicle section bar skeleton

Technical field

The utility model relates to a kind of switch cubicle section bar skeleton.

Background technology

Skeleton structure is the basis of switch cubicle, occupies considerable status in the overall formation of switch cubicle.Existing high and low pressure voltage switchgear generally has with products such as JYN1, KYN1, XGN2 with skeleton structure and is the section bar welding cabinet of representative and is two kinds of forms of bent plate assembling cabinet of representative with products such as KYN18, KYN28.The welding cabinet is mainly with the means of solder technology as the parts overlap joint, with cold-rolled steel sheet or hot-rolled steel class section bar such as parts such as angle steel, the channel-section steel cabinet skeleton that is welded, the skeleton construction of welding cabinet is simple, overlapping part contact strength height, cabinet rigidity is good, but has simultaneously that manufacturing process is coarse, precision is low, the cabinet welding deformation is big and defective such as the production cycle is long; The assembling cabinet is mainly with the means of living-article packaging technology as parts overlap joints, and the panel beating parts that cold-rolled steel sheet or aluminizing zine plate are made connect to form the cabinet skeleton according to the precalculated position size with the standard thread securing member.Defectives such as assembling cabinet manufacturing process advanced person, assembly precision are high and with short production cycle, but it is comparatively complicated to have skeleton construction simultaneously, and part processing cost height, overlapping part contact strength are relatively poor, and the cabinet integral rigidity is weak.

Utility model content the purpose of this utility model provides a kind of switch cubicle section bar skeleton, with solve existing skeleton construction complexity, the overlapping part contact strength is relatively poor, the problem that the cabinet integral rigidity is weak.

The utility model is assembled into the switch cubicle skeleton by section bar and connector; Described switch cubicle skeleton is made up of left frame, correct frame and crossbeam, and left frame is connected by connector with crossbeam with correct frame.

The utility model skeleton adopts the section bar part as main basic component, and the framework section bar cross-sectional profiles is a rectangle, is equipped with T type groove at the four sides, and transverse section of section material integral body is sealing, thin-walled shape.The section bar wall thickness is designed to different-thickness according to its stressing conditions, and inner chamber is a plurality of special-shaped chambeies, has avoided the waste to material of existing section bar circle or the same wall thickness of rectangular inner cavity.The design concept of T type groove not only is convenient to realize the convenient assembling of various directions but also is had characteristics such as corner angle are clearly demarcated, the lines flow smoothly; Section bar part through the particular design cross section has characteristics such as the raw material of saving, bending strength height.

Adopt connector, angle brace and bearing pin to be connected between the utility model framework section bar and be assembled into the cabinet skeleton, can guarantee assembly precision height, intensity height and the good rigidity of structure in conjunction with section bar favorable mechanical performance.Simultaneously, the big plane that has circular hole on the angle brace has the dual-use function of strengthening joint stiffness and realizing on-the-spot and cabinet.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment

Fig. 1 shows structural representation of the present utility model; Be assembled into switch cubicle skeleton 15 by section bar 1 and connector 4; Switch cubicle skeleton 15 is made up of left frame 8, correct frame 7 and crossbeam 9, and left frame is connected by connector 4 with crossbeam 9 with correct frame.Spring 14 is housed on the connector 4.

Eight edges and corners of switch cubicle skeleton 15 are equipped with angle brace 3.Have circular hole 10 on the angle brace.

Fig. 2 shows the cutaway view of correct frame, left frame and correct frame symmetry.

Skeleton 15 adopts the section bar part as main basic component, and the framework section bar cross-sectional profiles is a rectangle, is equipped with T type groove 11 at the four sides, and four jiaos of section bar 1 are provided with location hole 12.Transverse section of section material integral body is sealing, thin-walled shape.The section bar wall thickness is designed to different-thickness according to its stressing conditions, and inner chamber is a plurality of special-shaped chambeies, has avoided the waste to material of existing section bar circle or the same wall thickness of rectangular inner cavity.The design concept of T type groove 11 not only is convenient to realize the convenient assembling of various directions but also is had characteristics such as corner angle are clearly demarcated, the lines flow smoothly; Section bar part through the particular design cross section has characteristics such as the raw material of saving, bending strength height.

Fig. 7 shows first kind of execution mode of the utility model medium section cross section, and the inner chamber 13 of section bar 1 is the rectangle abnormity chamber of four jiaos of band grooves.

Fig. 8 shows second kind of execution mode of the utility model medium section cross section, and the inner chamber 13 of section bar 1 is the circular special-shaped chamber of four sides with cone tank.

Fig. 3-6 shows the connection layout of switch cubicle skeleton 15, and the connector 4 that adopts between the framework section bar, angle brace 3 combine section bar favorable mechanical performance with the mode of being fixedly connected of bearing pin 2 can guarantee to assemble high accuracy, intensity height and the good rigidity of structure.

A left side (right side) framework symmetry is made up of rectangular shaped rim and intermediate proximate matter.

As Fig. 3 and shown in Figure 5, the combination connecting mode of " bearing pin+angle brace " is adopted in the assembling of four drift angles of rectangular shaped rim.Bearing pin 2 is plugged at 1 place at section bar, load onto spring nut 5 at another section bar 1 place, the end face of another root section bar of needs butt joints is enclosed within on the bearing pin 2, the angle brace 3 that T type bolt 6 and spring washer, plain washer and nut will be housed in advance again abuts against overlap joint corner, T connector is colluded at T type groove inwall, fastening nut is then finished the overlap joint of a drift angle of left frame of switch cubicle section bar skeleton.Other three drift angles can assemble as method.

The two kinds of modes that are equipped with of intermediate proximate matter are formed by connecting.

A kind of connected mode is only used the connected mode of " connector ", as shown in Figure 3.One end of band T connector in the connector 4 is inserted in the T type groove 11 of section bar 1, and turn clockwise 90 °, make T connector catch on the inboard of the T type groove 11 of section bar 1.Another root section bar of needs butt joint is enclosed within on the connector 4, and when screw was tightened, screw promoted connector 4 and moves right.This relative motion produces two results: 1. two section bar connecting portions are tightened up and are close together; 2. connector 4 is inner stressed, thereby has guaranteed the reliability of connector.When needs are taken connection apart, only screw need be screwed out, connector 4 will eject under the promotion of spring 14 automatically.

Another kind of connected mode adopts the combination connecting mode of " bearing pin+angle brace ", as shown in Figure 5.Concrete operations are carried out with the assembling process of four drift angles of aforementioned rectangular shaped rim; And the like, a final left side (right side) framework of forming.

After a left side (right side) framework is formed, pass through connector 4, T type bolt 6, standard spring washer, plain washer and nut and angle brace 3 with crossbeam 9, combination connecting mode according to " connector+angle brace ", and the used linkage editor of aforementioned intermediate proximate matter connected mode one, with connector left and right framework and crossbeam are coupled together, in eight edges and corners of section bar skeleton angle brace 3 is installed by the installation method of four drift angles of rectangular shaped rim then, is formed switch cubicle skeleton 15 at last.
