Abstract
The utility model relates to a device for improving installation and protection, i.e. an automatic extended parachute against fall, which comprises a parachute; the top of parachute is connected with the traction steel rope; the bottom of parachute is connected with the top of bucket; the spring is connected between the top of parachute and bucket; the parachute opens under the weight of bucket in normal operation and spring is stretched; when the bucket is suspended, the parachute retracts under the force of spring; the radiation width is greater than mine wall diameter; the parachute stops to fall on the wall in the process of shedding. The device has the advantages of simple structure, technical feasibility, safety and reliability.
Description
[technical field]
The utility model relates to a kind of lifting protection device for installing, promptly automatic extended position fall arrest umbrella stand.
[background technology]
In prior art, mine hoist equipment is made up of gig, steel rope and steel rope lower end bonded assembly manned (material) suspension bucket, once wire cable rupture is opened, then the suspension bucket under it can crash into tens meters, even the down-hole of going up km, employee will not survive in it, and material decreases to the greatest extent.Same device also has the elevator in the skyscraper.
[utility model content]
The purpose of this utility model is that the automatic extended position fall arrest umbrella stand of saving oneself more effectively is provided at above-mentioned deficiency and after providing a kind of suspension bucket to come off.
Technical solution of the present utility model is: extended position fall arrest umbrella stand comprises a umbrella frame structure automatically, and the umbrella stand upper end is connected with haulage cable, and the umbrella stand lower end is connected with the suspension bucket upper end, is connected with at least one with upper spring between umbrella stand upper end and the suspension bucket.During normal the operation, umbrella stand is drawn back under the effect of suspension bucket weight, and this moment, spring was stretched; Once suspension bucket comes off, the umbrella stand that is stretched bounces back under action of the spring, and its radiation witdth is greater than mine borehole wall diameter, rides in the process of coming off on the borehole wall and stops falling.
Described umbrella frame structure comprises at least by two relative bonded assembly levers and hinged with aforementioned lever middle part respectively by two lever one ends at least, the other end and suspension bucket pivotally attached lever composition.
The utility model has the advantages that: utilize the structural principle of width that umbrella struts width when shrinking,, be used on the suspension bucket through additional strengthening, safety Design, have simple in structure, technical feasibility, safe and reliable advantage.
Below in conjunction with accompanying drawing the utility model is described in further detail.
[description of drawings]
Structure diagram when Fig. 1 is the utility model installation;
Fig. 2 is that the utility model chases after backward structural representation sketch.
[specific embodiment]
Referring to Fig. 1, its umbrella stand upper end of extended position fall arrest umbrella stand is connected with haulage cable 1 automatically, and the umbrella stand lower end is connected with suspension bucket 2 upper ends, is connected with two springs 3 between umbrella stand upper end and the suspension bucket 2.Spring 3 lower ends are connected with suspension bucket 2.Umbrella stand is movably hinged with lever 8,9 (being at least two) middle part respectively by four levers 4,5,6,7 (being at least two) end in this example, and the other end and suspension bucket 2 top movable are hinged, and lever 8,9 converges connection on top.
The umbrella stand shape resembles an empty umbrella stand that removes umbrella cloth and umbrella handle very much, and umbrella handle is changed into an extension spring 3, and spring 3 upper ends tie up to the umbrella point, and the lower end is connected on the suspension bucket 2.Top steel rope 1 end that ties up to of umbrella stand, the umbrella stand bottom is linked to each other with suspension bucket 2 tops by " umbrella support " root.
During normal the use, steel rope 1 is mentioned umbrella stand, and suspension bucket 2 is suspended in the umbrella stand lower end, and gravity pulls into straight shape with umbrella stand, and umbrella arm bar 4,5,6,7,8,9 is sagging all around, and umbrella central spring 3 is elongated, and the umbrella stand transverse diameter is less than suspension bucket 2 width, but free lifting like this.
Referring to Fig. 2, once steel rope 1 breaks, suspension bucket 2 loses gravity, central spring 3 lose the pulling force amount and shrink shorten, with the umbrella point pull to the below, blocked by suspension bucket 2 top snap rings, at this moment, four sides umbrella arm 4,5,6,7,8,9 is by vertically becoming laterally, and the diameter of umbrella stand can enlarge several times; umbrella arm bar 8,9 ends can support or be hooked on above the well arm 10, and making falls stops and escaping danger.
Claims (2)
1, a kind of automatic extended position fall arrest umbrella stand, it is characterized in that it comprises a umbrella frame structure, the umbrella stand upper end is connected with haulage cable (1), and the umbrella stand lower end is connected with suspension bucket (2) upper end, is connected with at least one with upper spring (3) between umbrella stand upper end and the suspension bucket (2).
2, according to the described automatic extended position fall arrest umbrella stand of claim 1, it is characterized in that described umbrella frame structure comprises at least by two relative bonded assembly levers (8), (9) and hinged with aforementioned lever (8), (9) middle part respectively by two levers (4), (6) one ends at least, the other end and suspension bucket (2) pivotally attached lever composition.
