Abstract
The utility model discloses a flame-proof mining variable-frequency adjustable-speed narrow rail battery car traction motor which includes an insulating sleeve, a junction box, an electric motor, a winding connector and a conductive rod. The winding connector is fixed on the conductive rod. The traction motor also includes fixing bolts. The inside of the junction box is provided with an upper middle plate and a lower middle plate. The upper middle plate and the lower middle plate are fixed together via the fixing bolts to form a middle plate. The insulating sleeve is arranged on the middle plate. The conductive rod passes through the insulating sleeve and is fixed on the middle plate via a nut. The junction box is arranged on the motor. The flame-proof mining variable-frequency adjustable-speed narrow rail battery car traction motor solves the assembly difficulty through changing the structure, eliminates the safety hidden trouble caused by poor assembly quality, and has the advantages of high installation efficiency and excellent safety performance.
Description
Technical field
The utility model relates to a kind of motor, specifically, relates to a kind of explosion-proof mining frequency control narrow gauge battery vehicle traction motor.
Background technology
GENERAL TYPE frequency control traction motor is specialized in mining electric locomotive and Tunnel Engineering electric locomotive as the usefulness of doing traction power, present explosion-proof mining frequency control narrow gauge battery vehicle traction motor, owing to be subjected to locomotive installing space and the characteristics conditionality of motor own, the motor internal space is too little, be difficult to make conducting rod to be fixed on the middle plate, namely allow to install, after the installation, the problems such as creepage distance is inadequate between loose contact, the connector lug often appear in motor, cause the potential safety hazards such as short circuit.
The utility model content
The purpose of this utility model is to solve the problem of prior art assembling difficulty, poor safety performance, provides a kind of installation effectiveness high, the explosion-proof mining frequency control narrow gauge battery vehicle traction motor that security performance is good.
For achieving the above object, the utility model provides following technical scheme: comprise insulating sleeve, terminal box, motor, winding connection head, conducting rod, the winding connection head is fixed on the conducting rod, it is characterized in that: also comprise set bolt, be provided with upper plate and lower plate in the terminal box, upper plate and lower plate are fixed as one with set bolt and form a middle plate, insulating sleeve is installed on the described middle plate, described conducting rod passes insulating sleeve and is fixed on the described middle plate with nut, and terminal box is installed on the motor.
The beneficial effects of the utility model are: the utility model is split as upper plate and lower plate two parts with middle plate, installing conducting rod is fixed as one again, solved an assembling difficult problem by change structure, eliminated the potential safety hazard that causes because of assembly quality, improve the general assembly efficient of motor, reduced the security incident that the quality problems that cause because of assembling cause.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the structure chart of prior art;
Fig. 2 is structure chart of the present utility model;
Wherein: 1. insulating sleeve, 2. terminal box, 3. set bolt, 4. in plate, 41. upper plates, 42. lower plates, 5. motor, 6. winding connection head, 7. conducting rod.
Embodiment
Referring to accompanying drawing, the utility model comprises insulating sleeve 1, terminal box 2, set bolt 3, upper plate 41, lower plate 42, motor 5, winding connection head 6, conducting rod 7.
When conducting rod 7 is installed, first winding connection head 6 is fixed on the conducting rod 7, upper plate 42 and lower plate 42 usefulness set bolts 3 are fixed as one form a middle plate, then insulating sleeve 1 is installed on the described middle plate, conducting rod 7 is passed insulating sleeve 1 and be fixed on the described middle plate with nut by the normal mounting method, after the passed examination, terminal box 2 is fixed on the motor 5.
The utility model is upper plate and lower plate in middle plate punishment, make motor that larger installing space be arranged, be more prone to install conducting rod, solved an assembling difficult problem, eliminated the potential safety hazard that causes because of assembly quality, improve the general assembly efficient of motor, reduced the security incident that the quality problems that cause because of assembling cause.
