Description

Rack for contact transmission system in high-voltage substation

Technical Field

The utility model relates to the power supply field especially involves a rack for contact transmission system in high voltage substation.

Background

The existing rack is mainly used for a contact transmission system in a 1100KV high-voltage transformer substation, and the product is originally welded and processed by a 45# steel square rack and a shaft and is used for controlling a moving contact to operate on and off; this product operates in the air, and original weight is heavy, needs 4 protection crane span structures to need adopt the lifting device to assist during the installation, installation cost and time are higher. Meanwhile, the end part of the existing rack is of a right-angle structure, and the rack is easy to fall off when being pulled down finally in the using process. Therefore, it is necessary to provide a rack structure that is light, easy to process, easy to assemble, and not easy to fall off.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the technical problem and providing a rack for contact transmission system in high-voltage substation.

The purpose of the utility model is realized like this: the utility model provides a rack for contact transmission system in high voltage substation, includes the rack, its characterized in that: the rack comprises a square rack and a shaft, the square rack and the shaft are integrally formed, and the shaft is vertically arranged on the right side of the square rack; the square rack comprises a rack main body and a rack tail, wherein 15 complete teeth are arranged on the rack main body, the rack main body and the rack tail are in transition through an arc section, the radius of the arc section is R, and R is 20 mm; the height of the complete tooth is H, and H is 27 mm; the length of the square rack is L, and L is 640 mm; the length of the shaft is L2, the center line of the shaft is arranged at a position H2 away from the bottom of the square rack, L2 is 85mm, and H2 is 55 mm.

As a preferred technical scheme: the square rack and the shaft are integrally forged and manufactured in the machining center by adopting aluminum alloy.

As a preferred technical scheme: the included angle between the complete tooth and the vertical line is alpha, and the alpha angle is 25 DEG

The utility model adopts the integrated molding of the square rack and the shaft to replace the traditional process of separating the square rack and the shaft and then installing and combining the square rack and the shaft for use; the square rack and the shaft are forged and molded by adopting aluminum alloy, so that the quality is reduced, the strength is ensured, and the square rack and the shaft are convenient to mount at high altitude; the design of 25 degrees angle at the head of the square rack replaces the original right angle structure, and the rack still has the function of clamping when running to the limit, so that the rack is prevented from falling off.

Drawings

FIG. 1 is a schematic structural view of the present invention;

In the figure: 1. a rack; 2. a square rack; 3. a shaft; 4. a rack main body; 5. a tooth tail; 6. complete teeth; 7. a circular arc segment.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, which are not intended as limitations of the present invention: the utility model provides a rack for contact transmission system in high voltage substation, includes rack 1, its characterized in that: the rack 1 comprises a square rack 2 and a shaft 3, the square rack 2 and the shaft 3 are integrally formed, and the shaft 3 is vertically arranged on the right side of the square rack 2; the square rack 2 comprises a rack main body 4 and a rack tail 5, 15 complete teeth 6 are arranged on the rack main body 4, the rack main body 4 and the rack tail 5 are transited through an arc section 7, the radius of the arc section 7 is R, and R is 20 mm; the height of the complete tooth 6 is H, and H is 27 mm; the length of the square rack 2 is L, and L is 640 mm; the length of the shaft 3 is L2, the center line of the shaft 3 is arranged at a position H2 away from the bottom of the square rack 2, L2 is 85mm, and H2 is 55 mm. The square rack 2 and the shaft 3 are integrally forged and manufactured in the machining center by adopting aluminum alloy. The included angle between the complete tooth and the vertical line is alpha, and the alpha angle is 25 DEG

In the specific implementation: the utility model discloses a 7A04-T6 aluminum alloy integration is made, can alleviate product weight, satisfies product design operation requirement and life-span, and the installation does not need additional auxiliary assembly simultaneously, and the installation effectiveness promotes more than 5 times than original product. The original traditional process that the square rack and the shaft are separately processed and then are installed and combined for use is replaced by the square rack and the shaft integrated molding; the square rack and the shaft are forged and molded by adopting aluminum alloy, so that the quality is reduced, the strength is ensured, and the square rack and the shaft are convenient to mount at high altitude; the design of the 25-degree angle at the head of the square rack replaces the original right-angle structure, and the rack still has a clamping effect when running to the limit, so that the rack is prevented from falling off; and the surface precision can be effectively controlled by performing fine processing through the processing center after forging.
