Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of explosion -proof electrical machinery strength detection device, specifically, relates to explosion -proof electrical machinery strength detection device. BACKGROUND

[0002] Electrical boxes are an integral part of electrical equipment, and their main function is to provide a safe and reliable fixed position for various electrical components. Typically, electrical boxes have a cubic shape, and common types include panel and box types. These designs allow electrical components to be effectively organized and arranged for easy maintenance and repair. In modern industry, especially in the oil, chemical, and mining industries, explosion-proof distribution boxes are increasingly widely used. These industries often face flammable and explosive environments, so the design and manufacture of explosion-proof distribution boxes are particularly important. Explosion-proof distribution boxes not only meet the electrical safety of the equipment, but also need to have certain protective properties to cope with harsh working conditions. With the progress of technology, the types and specifications of explosion-proof distribution boxes are increasingly diverse, meeting the needs of different scenarios. Explosion-proof distribution boxes inevitably produce electric sparks during operation, which are caused by high temperatures generated when current flows. In production or rescue sites, if these electric sparks meet explosive gas mixtures in the air, they can easily cause explosions.

[0037] The detection assembly for stretching or extruding the object placed on the workbench 11 is connected to one side of the receiving table 14.

[0038] ​The detection assembly can test the mechanical strength performance of the electrical box shell by applying force in multiple directions to the electrical box shell, increase the functionality of the equipment, and make workers not need to repeatedly move the electrical box shell, facilitate the workers to detect the mechanical strength of the electrical box shell, reduce the cost of the enterprise to purchase the detection equipment, and improve the practicality of the equipment;

[0039] The scanning electron microscope 19 for high-precision detection of the surface of the detected object is fixedly connected outside the protective cabin 12;

[0040] The scanning electron microscope 19 is used for real-time detection of whether the surface strength of the electrical box shell appears a small crack or the overall appearance appears deformation when the electrical box shell is subjected to mechanical action, for the convenience of workers to record data during the detection process of the electrical box shell, and for the convenience of workers to optimize;

[0041] The receiving table 14 is fixedly connected with the driving motor 110, and the driving shaft of the driving motor 110 is coaxially fixedly connected with the driving disc 15.

[0042] As shown in Figures 1-6 The detection assembly includes a jacking cylinder 21 fixedly connected to the bottom plate 13, a telescopic shaft of the jacking cylinder 21 is fixedly connected to the transmission plate 22, two limiting columns 23 are both slidingly connected to the transmission plate 22, and the two ends of each limiting column 23 are respectively fixedly connected to the lower side of the workbench 11 and the upper side of the receiving table 14;

[0043] Two linkage plates 24 are respectively hingedly connected to the two sides of the transmission plate 22, one end of each linkage plate 24 away from the transmission plate 22 is hingedly connected to each clamping plate 25, and each clamping plate 25 away from the linkage plate 24 is fixedly connected to each first supporting block 26;

[0045] By directly driving the jacking cylinder 21, the sliding directions of the plurality of first supporting blocks 26 and the plurality of second supporting blocks 29 are controlled, and the mechanical strength of the electrical box shell is detected. When the plurality of first supporting blocks 26 and the plurality of second supporting blocks 29 move outward, the electrical box shell is subjected to a tensile action, and then after the tensile action is completed, the air tightness and strength of the electrical box shell are checked to see whether they meet the production standards. When the plurality of first supporting blocks 26 and the plurality of second supporting blocks 29 move inward, the electrical box shell is subjected to a limiting action, so that the lower impact hammer 17 does not deviate when it impinges on the electrical box shell. When the electrical box shell is subjected to an extrusion test, the impact hammer 17 is lowered, and then the plurality of first supporting blocks 26 and the plurality of second supporting blocks 29 are further moved inward, so that the mechanical strength of the other side of the electrical box shell is detected.

[0056] The surface shape of the electrical cabinet is provided with protruding and recessed parts, so that the shape of the surface of the electrical cabinet shell is irregular. The two connecting sleeves 45 are used to align the surface of the electrical cabinet shell, and then the receiving plate 211 is pressed towards the electrical cabinet shell, so that the rotating angle of the clamping sleeve 43 between the first clamping sleeve 41 and the second clamping sleeve 42 is automatically adjusted. Through the clamping hook assembly, when each receiving plate 211 moves towards the electrical cabinet shell, the electrical cabinet shell can be better limited, thereby facilitating the stretching or extrusion test of the electrical cabinet shell.

[0057] As shown in Figure 2 and Figure 4 , the opening groove 421 is formed in the second clamping sleeve 42, the stepped groove 422 is formed in the opening groove 421, the clamping sleeve 43 is threadedly connected with the clamping nut 46, and the clamping nut 46 abuts against the inner wall of the stepped groove 422.

[0059] The principle of the embodiment is as follows:

[0060] The telescopic shaft of the jacking cylinder 21 moves up, and the limiting column 23 moves up, and then the clamping plates 25 on both sides move on the first sliding grooves 111, and then the first supporting blocks 26 move, and then the first supporting blocks 26 are hinged through the first and second driving plates 27 and 28, and then the clamping blocks 210 move on the second sliding grooves 112, and through the linkage of the clamping blocks 210, when the first supporting blocks 26 move to one side, the clamping blocks 210 are driven to move through the first driving plate 27, and then the second supporting blocks 29 are driven to move through the second driving plate 28, so that the first supporting blocks 26 and the second supporting blocks 29 in multiple directions can move synchronously, and then the electrical box shell to be detected can be simultaneously subjected to extrusion or stretching in multiple directions, so that the mechanical strength of the electrical box shell can be better detected.

[0061] The surface shape of the electrical box has protruding and recessed parts, and the shape of the surface of the electrical box shell is irregular, the two connecting barrels 45 are used to position the surface of the electrical box shell, and then the receiving plates 211 are extruded towards the electrical box shell, and then the rotation angle of the clamping barrel 43 between the first and second clamping sleeves 41 and 42 is automatically adjusted, through the clamping hook assembly, when the receiving plates 211 move towards the electrical box shell, the electrical box shell can be better positioned, and then the electrical box shell can be conveniently stretched or extruded.

[0062] When the two connecting barrels 45 extrude or stretch the surface of the detected object, the clamping barrel 43 is the main component subjected to the force, the opening groove 421 is provided to facilitate the workers to install and dismount the clamping barrel 43 between the first and second clamping sleeves 41 and 42, and the stepped groove 422 is used to limit the clamping nut 46 when the clamping nut 46 threadedly clamps the clamping barrel 43 arranged, so as to ensure the stable rotation of the clamping barrel 43.
