Description
Technical field
The mechanical device of trapdoor is opened and closed the present invention relates to a kind of mechanical device, more particularly to a kind of pit shaft lifting means.
Background technology
At present, installed for auxiliary shaft lifting means, 9.5 meters of well head diameter is larger-diameter vertical bore,
To avoid work progress workmen's injures and deaths and pit shaft caused by falling object from high altitude from installing device damage, well head use using I-steel as
Girder sets up tower structure collar set, and laying checkered steel plate is totally-enclosed.Because personnel and equipment need above and below construction needs, fore shaft
Disk center opens position reserved opening, and reserved opening laying springboard, surrounding takes two-sided movable railing to protect.Because of usually upper people, blanking
During need to travel frequently over the region, not only Employee Security is difficult to ensure, and adds a cumbersome action.It is based on
Consideration in more convenient operation and security, installs the double opening hinge doors of a normally closed type, to be badly in need of solving in well head reserved opening
Certainly the problem of.
The content of the invention
In order to make up the deficiencies in the prior art, solve well head and travel frequently over employee and equipment, Employee Security is difficult to what is ensured
There is provided a kind of automatic shutter trapdoor for problem.
The present invention solve its technical problem technical scheme be：
Automatic shutter trapdoor, mainly by trapdoor, spacing safety rope, hoisting rope, hinge, limit switch I, hoist engine,
Support beam, fixed pulley I, fixed pulley II, hoisting rope channel-section steel, reinforcement and limit switch II are constituted, and the trapdoor described in it is two
Fan, trapdoor is that I-steel constitutes rectangular frame, and checkered steel plate is laid above, and trapdoor the right and left respectively connects two hinges
One end, on the basis of the hinge other end is fixed on, two fan doors of trapdoor bottom are symmetrical arranged a pair of hoisting rope channel-section steels, lift grooving
Steel is that channel-section steel constitutes U-shaped, and outwards, U-shaped bottom sets reinforcement, U-shaped channel opening end connection trapdoor side to U-shaped notch
The I-steel of edge, trapdoor is vertically arranged with hoisting rope channel-section steel, and the two fan doors on trapdoor top connect spacing safety rope, spacing peace
Full rope one end connection trapdoor one is fanned, and other end connection another fan of trapdoor, the length of spacing safety rope is opened equal to trapdoor
Length in back door, the setting of spacing safety rope and being arranged in the middle part of trapdoor same direction, trapdoor lower section for hoisting rope channel-section steel
Support beam is vertically arranged, support beam is that two channel-section steels are set, and fixed pulley I is set in the middle of two channel-section steel tops, bottom connects basis,
Bottom side sets fixed pulley II, and fixed pulley II sets hoisting rope one end on hoist engine, hoist engine to connect hoist engine on one side, separately
One end connection fixed pulley II, continues to connect fixed pulley I, hoisting rope, which is connected, to be divided into after fixed pulley I under two strands of continuation connection trapdoors
Two hoisting rope channel-section steels in portion, two strands of hoisting ropes are respectively along in the groove of two hoisting rope channel-section steels, until on connection trapdoor
On the left of I-steel, trapdoor, trapdoor center of rotation axis top sets limit switch I, and the contact of limit switch I is in trapdoor
Trapdoor is touched during opening, center of rotation axis left lower sets limit switch II, and the contact of limit switch II is closed in trapdoor
Hoisting rope channel-section steel is touched during conjunction.
The beneficial effects of the invention are as follows：
1st, one aspect of the present invention reduces the tedious work that bank man removes protection, improves bank man's operation
Environment, on the other hand effectively prevent falling object from high altitude danger, has ensured wellbore operations personal security.
2nd, trapdoor opening and closing of the present invention is flexible, and usually trapdoor is in closure state, when cage need to propose well head, in time
Trapdoor is opened, the time is opened wide to reduce unnecessary trapdoor.

Embodiment
In Fig. 1-4, automatic shutter trapdoor, mainly by trapdoor 1, spacing safety rope 2, hoisting rope 3, hinge 4, spacing
Switch I 5, hoist engine 6, support beam 7, fixed pulley I 8, fixed pulley II 9, hoisting rope channel-section steel 10, reinforcement 11 and limit switch II 12
Composition, the trapdoor 1 described in it is two fans, and trapdoor 1 is that I-steel constitutes rectangular frame, and checkered steel plate, well are laid above
The right and left of lid door 1 respectively connects two one end of hinge 4, on the basis of the other end of hinge 4 is fixed on, two fan doors of the bottom of trapdoor 1
A pair of hoisting rope channel-section steels 10 are symmetrical arranged, hoisting rope channel-section steel 10 is that channel-section steel constitutes U-shaped, and U-shaped notch is outside, U-shaped bottom
Reinforcement 11 is set, and U-shaped channel opening end connects the I-steel at the edge of trapdoor 1, and trapdoor 1 is vertical with hoisting rope channel-section steel 10 to be set
Put, the two fan doors on the top of trapdoor 1 connect spacing safety rope 2, and the spacing one end of safety rope 2 connection trapdoor 1 one is fanned, and the other end connects
Another fan of trapdoor 1 is connect, the length of spacing safety rope 2 is equal to trapdoor 1 and opens length, the setting of spacing safety rope 2 in back door
Support beam 7, support beam 7 are vertically arranged with the middle part below the same direction of trapdoor 1, trapdoor 1 that is arranged on of hoisting rope channel-section steel 10
