Abstract
The utility model relates to a bearing liner burnout preventing device which comprises a plunger and a spring positioned in the engine oil tube, a rack gear pinion mechanism, an air duct and an air door. The lower part of the rack gear is connected with the upper part of the plunger. The spring is wound around the lower half part of the rack gear. The rack gear and the pinion are meshed. The air door is arranged on the pinion shaft. The air door is positioned in the air duct. The pinion shaft is vertically crossed with the cables of the air duct and the air door through the air duct wall. When the oil enters the engine oil tube, the oil pressure pushes the plunger to drive the rack gear pinion and the air door to turn 90 degree and the air duct is opened and the engine works. When the air duct does not have the engine oil, the air duct is automatically closed and the engine is stopped working. The bearing liner burnout preventing device is a diesel engine and gasoline engine safety protection device with reasonable structure and easy use.
Description
The utility model relates to a kind of tilt-burning proof device, belongs to the work safety protective gear of the oily machine of bavin (vapour).
At present, the oily machine of the bavin of use (vapour) in case inorganic oil or machine oil open circuit when not supplying, tile kilning even machine burnout phenomenon will occur when work.
The purpose of this utility model is to have proposed a kind of tilt-burning proof device for addressing the above problem, in case in the machine oil pipe of this device during inorganic oil, piston drives tooth bar under spring action descending, air door on rack drives gear, gear shaft and the axle is made 90 degree and is rotated the airduct obstruction, and machine quits work under no air automatically.
The purpose of this utility model realizes by following measures: the utility model includes the machine oil pipe, piston, spring, pinion and rack, airduct and air door, wherein, piston, the Lower Half of spring and tooth bar all is positioned at the machine oil pipe, the lower end of tooth bar is connected the upper end of piston, spring is around the periphery of tooth bar Lower Half, spring lower end and piston upper end offset, the spring upper end offsets with machine oil pipe upper end, rack and pinion is meshed, and tooth bar top is connected with and starts the power-assisted stay cord, and air door is housed on the gear shaft, air door is positioned at airduct, and gear shaft passes the axis of wind pipe wall and airduct and the axis of air door all intersects vertically.
The utility model is rational in infrastructure, and is easy to use, low cost of manufacture, and the tile kilning phenomenon is the oily machine work safety of a kind of desirable bavin (vapour) protective gear in the time of preventing the work of the oily machine inorganic oil of bavin (vapour) effectively.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Fig. 1 is the plan view of the utility model tilt-burning proof device.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
By Fig. 1,2,3 know, present embodiment includes machine oil pipe (1), piston (2), spring (3), pinion and rack, airduct (8) and air door (6), wherein, piston (2), the Lower Half of spring (3) and tooth bar (4) all is positioned at machine oil pipe (1), the lower end of tooth bar (4) is connected the upper end of piston (2), spring (3) is around the periphery of tooth bar (4) Lower Half, spring (3) lower end and piston (2) upper end offset, the upper end offsets with machine oil pipe (1) upper end, tooth bar (4) is meshed with gear (5), air door (6) is housed on the gear shaft (7), air door (6) is positioned at airduct (8), gear shaft (7) passes the axis of wind pipe wall and airduct (8) and the axis of air door (6) all intersects vertically, and the power-assisted stay cord (9) of startup is arranged at tooth bar (4) top.
Its working principle is: machine oil pipe (1) enters machine oil from filler opening, and engine oil pressure promotes piston (2) drive tooth bar (4) and moves up, and tooth bar (4) driven gear (5) and air door (6) revolve and turn 90 degrees, and airduct (8) is open-minded, and machine is started working.When in the machine oil pipe (1) during inorganic oil, spring (3) promotes piston (2) and drives tooth bar (4) and move down, and tooth bar (4) driven gear (5) and air door (6) return and turn 90 degrees, and airduct (8) is closed, and machine does not have air and quits work.
If machine starts at need under cryogenic conditions, can be by starting power-assisted stay cord (9).
Claims (2)
1, a kind of tilt-burning proof device, include the machine oil pipe, piston, spring, pinion and rack, airduct and air door, it is characterized in that: piston (2), the Lower Half of spring (3) and tooth bar (4) all is positioned at machine oil pipe (1), the lower end of tooth bar (4) is connected the upper end of piston (2), spring (3) is around the periphery of tooth bar (4) Lower Half, its lower end and piston (2) upper end offsets, the upper end offsets with machine oil pipe (1) upper end, tooth bar (4) is meshed with gear (5), air door (6) is housed on the gear shaft (7), air door (6) is positioned at airduct (8), and gear shaft (7) passes the axis of wind pipe wall and airduct (8) and the axis of air door (6) all intersects vertically.
2, tilt-burning proof device according to claim 1 is characterized in that: the power-assisted stay cord (9) of startup is arranged at the top of tooth bar (4).
