Abstract
The utility model belongs to the field of explosion-proof three-phase asynchronous motor and specifically relates to an outlet structure of an explosion-proof motor. The outlet structure comprises a mounting plate. Rotation center of the mounting plate is provided with a through hole. A shell nosing which extends toward the through hole is arranged at the bottom inside the through hole. A rotary connection board is arranged on the outer wall of the upper end of the through hole. The shell nosing inside the through hole is provided with a first metal washer. A sealing ring and a second metal washer are successively arranged in the through hole. An outlet bucket is pressed at the upper end of the through hole of the mounting plate. The outlet bucket is fixedly connected on the connection board through compression bolts. A pipe joint is also fixedly connected on the upper portion of the outlet bucket. The outlet structure of the explosion-proof motor is suitable for outgoing lines of an explosion-proof motor for an air compressor, and has advantages as follows: operation is safe and reliable; installation and debugging are convenient; internal space of an air compressor is saved; and wire arrangement is convenient.
Description
Technical field
The utility model belongs to Flame-Proof Three-Phase Induction Motors field, specifically a kind of outlet structure of fire-proof motor.
Background technology
In recent years, air compressor in oil, coal, chemical industry development rapidly.And motor is the heart of air compressor, common electric machine can not meet the requirement that is used in air compressor in oil, coal, chemical industry.And common fire-proof motor because be subject to that its terminal box of constraint of electric clearance and creepage distance must do very large.Be subject to the impact of the restriction of air compressor inner space and wiring, winding displacement.Common flame-proof type explosion-proof motor is installed and must be amplified compressor inner space, and then the machine volume of compressor also will further amplify, the installing space of final air compressor also will increase.This has not only wasted material, has improved cost, and installation and maintenance are also inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of outlet structure of simple in structure, ingenious, rational fire-proof motor is provided, the in the situation that making air compressor constant in inner space, this outlet structure uses flame-proof type explosion-proof motor, saved cost, make use and maintenance convenient, also the standardized designs for air compressor provides possibility.
The technical scheme providing according to the utility model: a kind of outlet structure of fire-proof motor, be characterised in that: comprise mounting panel, the described mounting panel centre of gyration is provided with through hole, and described through hole inner bottom has to the closing in of extending in hole, through hole upper end outer wall has jatharapanvartanasana connecting plate, in the inner closing in of described through hole, be provided with the first metal washer, in described through hole, be also disposed with sealing ring, the second metal washer, outlet bucket press-fits in described mounting panel through hole upper end, hold-down bolt is fixedly connected on described outlet bucket on described connecting plate, described outlet bucket upper end is also fixedly connected with pipe joint.
As further improvement of the utility model, described pipe joint upper end is also provided with the protecting pipe for the protection of motor cable line.
As further improvement of the utility model, the centre of gyration of described sealing ring offers cable threading opening.
The utility model compared with prior art, advantage is: the outlet structure of the utility model fire-proof motor is applicable to the outlet of air compressor explosion-proof motor, has the advantages such as safe and reliable to operation, Installation and Debugging convenient, save air compressor machine inner space, winding displacement is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, comprise protecting pipe 1, pipe joint 2, outlet bucket 3, hold-down bolt 4, the first metal washer 5, sealing ring 6, the second metal washer 7, mounting panel 8, flame proof plane 9, cable threading opening 10, closing in 11 etc.
As shown in Figure 1, the utility model is a kind of outlet structure of fire-proof motor, comprise mounting panel 8, described mounting panel 8 centres of gyration are provided with through hole, and described through hole inner bottom has to the closing in 11 of extending in hole, through hole upper end outer wall has jatharapanvartanasana connecting plate 12, in the inner closing in 11 of described through hole, be provided with the first metal washer 5, in described through hole, be also disposed with sealing ring 6, the second metal washer 7, outlet bucket 3 press-fits in described mounting panel 8 through hole upper ends, hold-down bolt 4 is fixedly connected on described outlet bucket 3 on described connecting plate 12, described outlet bucket 3 upper ends are also fixedly connected with pipe joint 2, mounting panel 8 base plane are flame proof plane 9.
Described pipe joint 2 upper ends are also provided with the protecting pipe 1 for the protection of motor cable line.
The centre of gyration of described sealing ring 6 offers cable threading opening 10.
The course of work of the present utility model is as follows: motor is when assembling, first motor lead cable is drawn from the wire hole of mounting panel 8, (surface roughness of flame proof plane 9 is not more than 6.3 μ m in mounting panel 8 bottom flame proof planes 9, to scribble antirust oil, flatness is 0.06), with 8.8 grade bolts, the utility model is fixed on electric machine stand wire outlet seat, and guarantee that flame proof plane 9 fits on motor outlet wire seat, then on cable, put on successively the first metal washer 5, sealing ring 6, the second metal washer 7, outlet bucket 3, with the hold-down bolt 4 outlet bucket 3 that is fixed and clamped, make sealing ring 6 hold cable tightly and play sealed explosion-proof effect, then put pipe joint 2 and protecting pipe 1 protection motor cable line.
The outlet structure of the utility model fire-proof motor is applicable to the outlet of air compressor explosion-proof motor, has the advantages such as safe and reliable to operation, Installation and Debugging convenient, save air compressor machine inner space, winding displacement is convenient.
