Design goal of the present utility model can also reach by following measure:
Cage automatic safe curtain go up traction slider slideway 14, be positioned at safe blind 12 1 sides, promptly only be provided with one, correspondingly, on draw slide block 6, well head fixedly elasticity meet and discuss 2, haulage cable 9, leading sheave 10 etc. also only establish a cover.
The downslide stop gear of the top curtain bar of cage automatic safe curtain adopts the one section connecting chain that is connected between top curtain bar and the connection jar crossbeam 1.
The downslide stop gear of the top curtain bar of cage automatic safe curtain be the limit sliding chutes on the slideway 8 and be positioned on the curtain bar sliding sleeve of top, stop screw that its top slides up and down in limit sliding chutes.
Compared with the prior art the utility model has following advantage:
1. by the lifting of cage self, make the cage safe blind open automatically and close, realize cage safe blind automation control.
2. be active in one's movements, safe and reliable.
3. mechanism is simple, compact, reasonable, and processing, manufacturing, installation, maintenance are conveniently.
4. laborsaving, save time, cost economic.
5. practical, applied range.
The drawing of accompanying drawing is described as follows:
Fig. 1: the utility model structural representation front view
Fig. 2: the utility model structural representation lateral plan
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1,2 shows structure of the present utility model.It is mainly by safe blind 12, slideway 8, haulage cable 9, curtain bar connecting chain 13, on draw slide block 6, down draw slide block 7, on draw slider slideway 14, leading sheave 10, well head fixedly elasticity meet and discuss 2, the shaft bottom fixedly elasticity meet and discuss and 4 form.
Cage import and export above a connection jar crossbeam 1 is installed, two slideways 8 of vertical installation and one upward draw slider slideway 14 between connection jar crossbeam 1 and the cage base plate.Slideway 8 and 14 two ends up and down are welded on the slideway adapter plate 11, slideway adapter plate 11 by bolt on connection jar crossbeam 1 and cage base plate.
Safe blind 12 is made of several curtain bars, and curtain bar two ends have sliding sleeve, and sliding sleeve is enclosed within on the slideway 8 that is positioned at safe blind 12 both sides, can slide up and down along slideway 8, has curtain bar connecting chain 13 to connect between the curtain bar.Top curtain bar is connected on jar crossbeam 1 by one section connecting chain, plays the downslide position-limiting action.
Suspension ring and bottom curtain bar that one end of haulage cable 9 passes on each curtain bar link, and the other end is walked around the leading sheave 10 that is contained on the connection jar crossbeam 1 and linked with last traction slide block 6.Last traction slide block 6 is loaded on the traction slider slideway 14, can slide up and down along slideway 14.Last traction slider slideway 14 is positioned at safe blind 12 1 sides, and its outside external part end face is provided with elastic component, as with fixing elasticity 4 contacted the meeting and discussing of meeting and discussing of well head.
Well head fixedly elasticity to meet and discuss 2 be a T type member, it leans out the bottom face and is fixed with elasticity and meets and discusses, end face supports on the I-beam section 3 in derrick by bolt thereafter, derrick supports I-beam section 3 and is installed on the well head derrick.Well head fixedly elasticity is met and discussed 2 pairs and is gone up 6 up position-limiting actions of traction slide block.
The shaft bottom fixedly elasticity meet and discuss 4 structure and well head fixedly elasticity meet and discuss 2 with, be fixed in shaft bottom derrick cage guide and support on the I-beam section 5.Meet and discuss to be positioned at and lean out the end end face in shaft bottom fixedly meet and discuss 4 elasticity of elasticity, it under draw 7 descending position-limiting actions of slide block.
Connection jar crossbeam 1 adopts angle steel, and slideway 8 is round steel or steel pipe with last traction slider slideway 14, and the elasticity on the member 2,4,6,7 is met and discussed and can be adopted ebonite board or spring.All the other are steel component, do not have special processing request.
In the above-described embodiments, on draw slider slideway 14 and adopt one, be positioned at safe blind 12 1 sides, corresponding haulage cable 9, leading sheave 10 etc. are only established a cover.Also can respectively establish on one traction slider slideway 14 in the both sides of safe blind 12, go up traction slide block 6, well head fixedly elasticity meets and discusses 2, haulage cable 9, leading sheave 10 be provided with two covers accordingly.
The downslide stop gear of safe blind 12 top curtain bars also can adopt the slideway 8 that has limit sliding chutes and be positioned on the curtain bar sliding sleeve of top, stop screw that its top slides up and down in chute.
Operating principle:
When cage was in well head or bottom hole location, when promptly upper and lower well personnel passed in and out cage, the cage safe blind should be opened automatically; When the cage lifting moved, safe blind is SELF CL immediately; When cage moves to terminal point---when well head or shaft bottom, safe blind is opened again automatically.The automatic shutter process is as follows:
1. at well head, enter cage, cage and begin when descending when going into the well personnel, haulage cable 9 is loosening, and safe blind 12 is along with the decline of cage is moved downward to lower position by deadweight, SELF CL.
2. when cage comes downwards to bottom hole location, by the fixing elasticity 4 pairs of position-limiting actions of traction slide block 7 down of meeting and discussing in shaft bottom, force down on the traction slide block 7 and move, drive to carry on the safe blind 12 and close up above cage, safe blind 12 is opened automatically.
3. in the shaft station, when entering cage, cage, last well personnel begin when up, and safe blind 12 is by the operation of deadweight along with cage, moves down expansion, to lower position, SELF CL.
4. when cage goes upward to pithead position, by the fixing elasticity 2 pairs of position-limiting actions of going up traction slide blocks 6 of meeting and discussing of well head, on draw slide block 6 by haulage cable 9, make carry on the safe blind 12 close up, to the cage top, safe blind 12 is opened automatically.
