Abstract
The utility model relates to an automatic safety door with high reliability and applies for the automatic switching of the mine top of the cage lifting silo and the tank door on the top position and the safe locking of the tank door when a hoist is running. The utility model is characterized in that the door is driven by a cylinder (or hydraulic cylinder), and the cylinder (or hydraulic cylinder) is enclosed in the guide rail of the beam of the door and equipped with a cushioning unit, and a hinge connecting device is arranged on one end of the beam guide rail near the gallows vertical post, all of which protect the cylinder (or hydraulic cylinder) safely, and the safety door can be opened by rotating around a pin shaft and is convenient to lift the long materials. The utility model has the advantages of robust structure, stable running of the whole system, accurate positioning without impact, high ability of preventing the door from colliding with foreign objects, fast open speed, high reliability and reduced maintenance, and can adapts to tricking water in the field or other harsh environmental conditions, and has a wide applicability.
Description
One, technical field
The utility model relates to the high reliability automatic safety door, is particularly useful for the safety interlocking of jar door in mine cage winding shaft well head and down-hole stop position jar door automatic shutter and the gig fortune process.
Two, background technology
In the vertical shaft for mine elevator system, cage is a kind of multiduty lifting container, is used for lifting workman and required article etc., in order to guarantee the safety of lifting personnel and goods, especially staff's personal safety, safety door all is equipped with at the place, gangway, two ends of winding cage.The safety door that uses in the present domestic vertical shaft for mine system, mainly form by crossbeam, left frame, fence, its crossbeam two ends are generally fixed type, base cross members adopts the channel-section steel structure, open and close the vertical two ends that are arranged in safety door of cylinder (hydraulic actuating cylinder) of safety door, when door is opened, cylinder (hydraulic actuating cylinder) promotes safety door guide rail one end and upwards lifts, safety door is opened, though this version can be finished the switching work of safety door, but in the practice process, also there are the following problems: 1) lifting long material inconvenience at the scene; 2) the crossbeam shock resistance is poor; 3) because guide rail one end upwards lifts, cause operation guide rail unbalance stress, safety door impacted, and produce noise, even cause the blastic deformation to safety door, 4) poor reliability, maintenance is big, is difficult to adapt to harsies environment such as on-the-spot trickle.
Three, technology contents
(1) goal of the invention
In view of the weak point of prior art, it is stressed even that the object of the invention provides a kind of operation guide rail, avoids impulsive force, and system operates steadily, and can open vertically, is convenient to the high reliability automatic safety door of lifting long material.
(2) technical scheme
The utility model high reliability automatic safety door, it comprises cylinder (hydraulic actuating cylinder), pipeline, solenoid directional control valve is located at the safety door in the guide frame, the suspending rod and the road wheel that link with safety door, described cylinder (hydraulic actuating cylinder) is located on the beam guideway, beam guideway is provided with hinge joining means by an end place of derrick column, and solenoid directional control valve is connected with, and the cross sill of safety door is used the good mining i beam of shock resistance instead.
The utility model high reliability automatic safety door; beam guideway is combined into back the type structure by two channel-section steels; cylinder (hydraulic actuating cylinder) is located at osed top and returns in the type structure groove; countercylinder (hydraulic actuating cylinder) plays the better protect effect; be provided with the shock absorber of forming by outgate in the cylinder (hydraulic actuating cylinder); the hinge joining means of beam guideway end is made up of bearing and bearing pin, and is by bearing pin that beam guideway and bearing is hinged.Form by oil water separator, reducing valve, oil sprayer with solenoid directional control valve bonded assembly triplet.
(3) technique effect
The utility model high reliability automatic safety door is best suited in mine cage winding shaft well head and down-hole stop position jar door automatic shutter and the gig operational process jar safety interlocking of door.Adopt cylinder (hydraulic actuating cylinder) to drive, cylinder (hydraulic actuating cylinder) is enclosed in the beam guideway of door, and adopted shock absorber, be provided with hinge joining means at beam guideway by derrick column one end place, the cross sill of safety door is used the good mining i beam of shock resistance instead, compared with prior art, the safety door speed of travel is greater than 0.5m/ second, tractive force limit can reach 500 kilograms, countercylinder (hydraulic actuating cylinder) plays the better protect effect, safety door can be rotated around bearing pin and open, and is convenient to the lifting long material; The safety door structure is firm, the total system running steadily, putting in place accurately is not hit, and anti-foreign object collision ability is strong, and opening speed is fast, total system is arranged clean and tidy, outward appearance is neat, good reliability, and maintenance workload significantly reduces, can well adapt to the requirement of harsies environment such as on-the-spot trickle, have practicality widely.
