Embodiment 1

[0027] Embodiment 1: The present invention provides a detection device for a relay protection box, including a main body bracket 1, a control electric box 2, a protection box 3, a semicircular hanging tube 4, a sliding top shaft 5, a square insertion rod 501, and an electric cylinder 6 , an I-shaped pull plate 7, a positioning cylinder 701, a connecting support plate 8, a buffer belt 801, a tightening belt 9, a slider 10, a tension sensor 11 and an insertion shaft 12; The frame is composed of spaced supports, and a semicircular hanging tube 4 is hung and welded at the center of the two cross brace connecting rods at the top of the main body support 1, and the handle of the protection box 3 is hung in the semicircular hanging tube 4; the electric cylinder 6 is vertically supported and installed at the center of the space at the bottom of the main frame 1, and its telescopic rod runs through and connects to the middle section of the I-shaped pull plate 7; There is a tension sens...

Embodiment 2

[0036] Embodiment 2: On the basis of Embodiment 1, the slidable top shaft 5 and the semicircular hanging tube 4, the retractable square insert rod, and the detachable design of the elastic buffer belt are added, so that the At the same time as the handle strength test, the body strength test of the protection box can also be realized. The specific test process is as follows: first, slide the top shaft 5 to the upper half of the main support frame 1, and push the vertical shaft on the semicircle hanging tube 4. Support the slide plate so that it is located in the middle of the two cross-bracing connecting rods at the top of the main frame 1, and then complete the handle strength test according to the test method in Example 1, then perform the box strength test of the protective box, and then according to the protective box The thickness dimension of the box body slides the sliding top shaft 5 to the roughly proper position in the middle of the main body bracket 1, and pushes the...

Abstract

The invention provides a detection device for a relay protection box. The detection device includes a main body support frame, a control box, a protective box, a semicircular hanging cylinder, bufferbelts, a tightening belt, sliding blocks, a tension sensor and an insertion shaft. The main body support frame consists of two n-shaped frame spacing supports at the front and rear, and the semicircular hanging cylinder is hung and welded at the center of two cross brace connecting rods at the top end of the main body support frame, and a handle of the protective box is hung in the semicircular hanging cylinder; an electric cylinder is vertically supported and installed at the center of the bottom space of the main body support frame, and a telescopic rod of the electric cylinder is connectedto the middle section of an I-shaped pulling plate in a penetrating manner; the tension sensor is rotatably connected at the center between the I-shaped pulling plate and a connecting supporting plate; the tightening belt penetrates through and presses the protective box, and the left end and the right end of the tightening belt are rotatably connected with two sliding blocks, respectively; and the insertion shaft uses a spring-loaded pull-out method which can quickly pull the tightening belt back and out, and thus the tightening and positioning operation of the protective box is convenient and efficient.

Description

technical field [0001] The invention belongs to the technical field of electrical box detection equipment, and more specifically relates to a detection device for a relay protection box. Background technique [0002] The relay protection box is a box for the relay tester. It can effectively shield and protect the relay tester, and has the effect of dustproof and rainproof. It is an indispensable supporting device for the relay tester. Because the relay protection box For large-scale production applications, a detection device for relay protection boxes is needed to carry out sampling tests and inspections before leaving the factory. [0003] At present, the detection devices used in the prior art generally have a poor stable positioning effect of the protection box, and lack of buffer protection. During the test process, it is easy to cause impact debris to hurt people, and the safety is low, and there is a protection box in the test. The placement and positioning operation...
