Abstract
The utility model discloses a door opening mechanism of an explosion-proof double-power supply vacuum electromagnetic starter for a coal mine fan. The mechanism comprises a door body and a handle, wherein a through hole is formed on the middle part of the handle; a handle rotating shaft is arranged in the through hole; the handle is connected with the front end of the handle rotating shaft through a cylindrical pin which vertically passes through the handle; a door handle seat is arranged on the door body and is a cylinder of which the center is provided with a handle mounting hole; the handle rotating shaft is inserted into the handle mounting hole; a handle shaft inserting sleeve is sleeved between the handle rotating shaft and the door handle seat; an eccentric wheel is clamped at the rear end of the handle rotating shaft; and an eccentric wheel frame is arranged outside the eccentric wheel and is a rectangular metal frame, and an inner hole of the frame is rectangular. A box door is quickly opened and closed through displacement controlled by the eccentric quantity of the eccentric wheel in the box door, and the mechanism has a simple and reasonable structure, is convenient to operate, and greatly shortens time for opening and closing the box door each time.
Description
Technical field:
The utility model relates to blower fan field, colliery, specifically is a kind of colliery blower fan flame-proof type dual power supply vacuum electromagnetic starter door-opening mechanism.
Background technology:
The colliery blower fan is the starting drive of dual power supply blower fan independently under the coal mine with the flame-proof type dual power supply vacuum electromagnetic starter, its critical piece is installed in the steel casing, when going wrong, all need to open chamber door at maintenance or equipment, be at the outside setting-up eccentricity wheel of casing in the past, use eccentric wheel to open the door, because eccentric wheel is a disc, bad assurance is exerted oneself nowhere, it is very inconvenient to operate, and therefore imagination provides a kind of new door-opening mechanism to replace.
Summary of the invention:
The utility model provides a kind of colliery blower fan flame-proof type dual power supply vacuum electromagnetic starter door-opening mechanism, by coming the high-speed switch chamber door in the inner displacement of chamber door with eccentric offset control, it is simple and reasonable, and is easy to operate, has significantly reduced the time of each switch chamber door.
The technical solution adopted in the utility model is:
A kind of colliery blower fan flame-proof type dual power supply vacuum electromagnetic starter door-opening mechanism, comprise a body, handle: have one handle, there is through hole at handle middle part, and arm pivot post is installed in the through hole, is connected by the straight pin that vertically passes handle between handle and the arm pivot post front end; Door is equipped with the door handle seat on the body, and the door handle seat has the cylinder of handle installing hole for the center, and arm pivot post inserts in the described handle installing hole, is set with the Handle axis edge between arm pivot post and the door handle seat and overlaps; The rear end of arm pivot post is installed with eccentric wheel, and eccentric wheel is equipped with the eccentric wheel frame outward.
Described eccentric wheel frame is the rectangular metal frame, and its endoporus also is a rectangle.
Advantage of the present utility model is:
The utility model is by coming the high-speed switch chamber door in the inner displacement with eccentric offset control of chamber door, and it is simple and reasonable, and is easy to operate, has significantly reduced the time of each switch chamber door.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
A kind of colliery blower fan flame-proof type dual power supply vacuum electromagnetic starter door-opening mechanism, comprise a body, handle 7: have one handle 7, there is through hole at handle 7 middle parts, and arm pivot post 4 is installed in the through hole, are connected by the straight pin 6 that vertically passes handle between handle 7 and arm pivot post 4 front ends; Door is equipped with door handle seat 3 on the body, and door handle seat 3 has the cylinder of handle installing hole for the center, and arm pivot post 4 inserts in the described handle installing hole, is set with the Handle axis edge between arm pivot post 4 and the door handle seat 3 and overlaps 5; The rear end of arm pivot post 4 is installed with eccentric wheel 1, outside the eccentric wheel 1 eccentric wheel frame 2 is installed, and eccentric wheel frame 2 is the rectangular metal frame, and its endoporus also is a rectangle.
During use, utilize in the inner displacement with eccentric offset control of chamber door and come the high-speed switch chamber door, door handle connects with eccentric wheel, by handle the drive eccentric wheel rotation that rotatablely moves.
When closing chamber door, door handle is placed on left position and is rotated counterclockwise about 20 degree then, chamber door is pushed inward put in place the flange profile that makes chamber door and the flange profile of casing fasten mutually, door handle is rotated counterclockwise to move down until chamber door then and puts in place to the flange top that location right is withstood casing with upper bearing plate.
When unpacking door, door handle be placed on location right then dextrorotation go to left position and withstand the flange bottom of casing with lower support plate, treat to move on on the chamber door position flange profile of chamber door and the flange profile of casing thrown off mutually, chamber door be pulled outwardly put in place.
Come the switch chamber door to make the cabinet design outward appearance more succinct by the inner displacement of chamber door with eccentric offset control.Changed the present situation of in the past externally opening the door with eccentric wheel.
