Abstract
The utility model provides a hydraulic test device of a junction box of an explosion-proof motor, which comprises a press plate, sealing gaskets, an end upper press plate, an end lower press plate, a connecting screw, a press block, a bolt and a nut, wherein the press plate is pressed between an inner lead hole of the junction box and a power interface hole, and the sealing gaskets are placed between explosion-proof surfaces of the junction box and between the upper surface of the junction box and the press plate. The end upper press plate, the end lower press plate, the connecting screw, the press block and the bolt form an end pressing structure to achieve pressing of the explosion-proof surfaces. The hydraulic test device of the junction box of the explosion-proof motor is simple in structure, convenient to manufacture, easy to install and dismantle, particularly suitable for hydraulic tests of the junction box of the explosion-proof motor after processing and remarkable in effects.
Description
Technical field
The utility model relates to the fire proof motor terminal box, relates in particular to fire proof motor terminal box water test unit.
Background technology
Fire proof motor terminal box water test unit is installed in outside the fire proof motor terminal box, mainly seals, and is used to install the hydraulic testing of the explosion-proof connection box for motor in back.Conventional fire proof motor terminal box water test unit has following 2 deficiencies: one, use conventional fire proof motor terminal box water test unit; Can only before terminal box processing, test; For the fire proof motor terminal box that needs are produced in batches, the hydraulic testing is inconvenience extremely, and the manufacturing cycle is long; Two, use conventional fire proof motor terminal box water test unit, the end explosion suppresion surface can not guarantee the sealing effectiveness between connector cover and the junction box seat after using the pressing plate sealing.
The utility model content
The purpose of the utility model is to overcome weak point of the prior art; Another kind of fire proof motor terminal box water test unit is provided; Thereby under the prerequisite that realizes terminal box hydraulic testing sealing, use fire proof motor terminal box water test unit; Be prone to install, dismantle, and shortened the manufacturing cycle of terminal box.
The technical scheme of the utility model is following:
A kind of fire proof motor terminal box water test unit comprises pressing plate, sealing gasket, end top board, end lower platen, connecting screw rod, briquetting, bolt and nut; Said pressing plate is pressed between terminal box upper surface and the electric machine stand end plane, and said sealing gasket is placed between the terminal box explosion suppresion surface and between terminal box upper surface and the pressing plate; Said end top board, end lower platen, connecting screw rod, briquetting, bolt and nut constitute the end compressing structure; By bolted, briquetting is pressed in the terminal box explosion suppresion surface outside between the terminal box explosion suppresion surface, and end top board, end lower platen are pressed in the briquetting outside, and connecting screw rod and nut are fastening with end top board, end lower platen.
The useful technique effect of the utility model is:
1) manufacturing of the utility model part is simple.All parts are for being prone to workpiece and standard component, and the workpiece difficulty of processing is low, and standard component is bought convenient.
2) the utility model is installed simple.All parts only need use the torque spanner unification to tighten, and do not have the part of being inconvenient to install.
3) the utility model adaptability is strong.The end compressing structure can adapt to different terminal box end constructions with the briquetting height through regulating connecting screw rod length.
4) the utility model long service life.Can not cause damage to fire proof motor terminal box water test unit, the parts long service life in the hydraulic testing process.Can be through the 1.5MPa pressure test of standard GB 3836.2-2010 " explosive atmosphere part 2: " requirement by the equipment of flameproof enclosure " d " protection.
5) the utility model can reduce the outlet box manufacturing cycle.The hydraulic testing can be so that unified arrange test after outlet box processed, and the dimensional discrepancy that can avoid again clamping to cause, reduced the outlet box manufacturing cycle.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that enlarged drawing is looked on the right side at A place among Fig. 1.
Embodiment
For enabling further to understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited about the utility model.
As shown in Figure 1, the utility model fire proof motor terminal box water test unit comprises pressing plate 1, sealing gasket 2, end top board 3, end lower platen 4, connecting screw rod 5, briquetting 6, bolt 7 and nut 8.Pressing plate 1 is pressed between terminal box inner lead hole (being upper surface) and power interface hole (being the support end plane), and pressing plate 1 has the position, hole that cooperates with terminal box, is used for connection, fastening, sealing.Sealing gasket 2 is placed between terminal box explosion suppresion surface 10 and the terminal box explosion suppresion surface 10 (see figure 1) between (see figure 2) and terminal box upper surface and the pressing plate 1.
As shown in Figure 2, end top board 3, end lower platen 4, connecting screw rod 5, briquetting 6, bolt 7 and nut 8 constitute end compressing structure 9 together, realize compressing of terminal box explosion suppresion surface.Fastening by bolt 7 between two explosion suppresion surfaces 10 of terminal box, briquetting 6 is pressed in two explosion suppresion surface 10 outsides of terminal box, and end top board 3, end lower platen 4 are pressed in briquetting 6 outsides, and connecting screw rod 5 and nut 8 are fastening with end top board 3, end lower platen 4.Through the length of adjusting connecting screw rod 5 and the height of briquetting 6, can make end compressing structure 9 adapt to different terminal box end constructions.
When the utility model fire proof motor terminal box water test unit is installed; Sealing gasket 2 with terminal box explosion suppresion surface place, terminal box upper surface place fills up earlier; Notice that sealing gasket 2 aligns with the position, hole of terminal box upper surface, then pressing plate 1 is installed, and with torque spanner that here bolt, nut is fastening.Erection bolt 7, briquetting 6, end top board 3, end lower platen 4 successively on the explosion suppresion surface of the end of fire proof motor terminal box again; Through the distance between connecting screw rod 5 and nut 8 adjustment end top boards 3, the end lower platen 4, and with torque spanner connecting screw rod 5, nut 8 are fastening here.
Above-described only is the preferred implementation of the utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of the basic design that does not break away from the utility model, all should think to be included within the protection domain of the utility model.
