Description
Technical field
The utility model is related to a kind of lowering or hoisting gear, more particularly to a kind of drawstring of Spiral digging machine draws lowering or hoisting gear.
Background technology
Spiral digging machine is also known as rotary drilling rig, is to carry out road traffic, the important work of skyscraper construction related to other
Tool.Spiral digging machine is a kind of comprehensive rig, and it generally comprises fuselage, connecting portion and homework department etc., and connecting portion is used to connect machine
Body and homework department, homework department are that, for digging mechanisms such as the various drill bits of operation, it can carry out dry dig using short augers
Operation, can also carry out wet excavation operation using rotary bit in the case of mud off.It is broken that Spiral digging machine can coordinate block stamp to bore
Borehole operation is carried out after firm hard formation, if coordinating enlarged footing drilling tool, ream operation can be carried out in bottom hole.Spiral digging machine uses multilayer
Telescopic drill rod, drilling non-cutting time is few, and labor intensity is low, it is not necessary to which mud circulates deslagging, cost-effective, pollution-free, especially
It is suitable for the foundation construction of urban construction.
At present, China is in quick development construction period, and with the enlarging in city, the use for Spiral digging machine is also got over
Come more frequent, but the lowering or hoisting gear presence of Spiral digging machine can not be automatically adjusted under prior art, easily occur unreeling too fast, cause to draw
The shortcoming for drawknot confusion of restricting, with the fast development of building trade, the increasingly fierceness, therefore need research and development one badly of related industry competition
Kind can automatically adjust, be not in unreel it is too fast, it is therefore prevented that the drawstring traction lifting dress of the chaotic Spiral digging machine of drawstring drawknot
Put.
Utility model content
(1) technical problem to be solved
The utility model easily unreels to overcome the lowering or hoisting gear of Spiral digging machine under prior art not automatically adjust
Shortcoming that is too fast, causing drawstring drawknot chaotic, the technical problems to be solved in the utility model, which is to provide one kind, to be automatically adjusted,
Be not in unreel it is too fast, it is therefore prevented that the drawstring traction lowering or hoisting gear of the chaotic Spiral digging machine of drawstring drawknot.
(2) technical scheme
In order to solve the above-mentioned technical problem, the utility model provides the drawstring traction lifting dress of such a Spiral digging machine
Put, include slideway, sliding block, rotary digging mechanism, the first directive wheel, the second directive wheel, spring, travel switch, hoist engine and drawstring；
Rotary digging mechanism is installed on being provided with the left of slideway on the left of sliding block, sliding block, slideway top left hand is installed with the first directive wheel,
It is hinged with the right side of slideway top below the second directive wheel, the second directive wheel and is connected with spring, it is right that the spring other end is connected to slideway
Side, is provided with travel switch between the first directive wheel and the second directive wheel, on the right side of sliding block on hoist engine is installed, rotary digging mechanism with
Drawstring is connected between hoist engine, drawstring passes through the first directive wheel and the second directive wheel.
Preferably, travel switch selects microswitch type.
Preferably, drawstring selects round-strand rope.
Operation principle：In device of the present utility model connection, lower end is connected by link with fuselage on the right side of slideway, is led to
Cross link device of the present utility model is fixedly mounted on fuselage, it is necessary to will rotation in device of the present utility model work
When digging machine structure is declined for rotary digging operation, control hoist engine is rotated counterclockwise, so as to unreel drawstring, drives rotary digging mechanism and sliding block
Moved downward on slideway, in this motion process, because the tractive force of drawstring and internal tension force, drawstring is to the second directive wheel
With a downward pressure, and because the second directive wheel is to be hinged with slideway, so as to cause the second directive wheel compression spring suitable
Hour hands turn over certain angle, and the second directive wheel is unreeled away from travel switch, hoist engine, if unreeling excessive velocities, drawstring is just
It can fluff, the interior tension force of drawstring diminishes, and drawstring diminishes to the pressure of the second directive wheel, by making by the elastic force of compression spring
Two directive wheels turn over certain angle counterclockwise, when the second directive wheel, which is rotated counterclockwise, touches travel switch, travel switch control
Hoist engine processed stops unreeling, and rotary digging mechanism and sliding block continue to move downward, when rotary digging mechanism and sliding block continue to move downward again
When tensing drawstring, the second directive wheel compression spring is set to turn over certain angle clockwise again, the second directive wheel is away from travel switch, OK
Cheng Kaiguan control hoist engines start to unreel again, continuous this motion, so as to ensure rotary digging mechanism and sliding block Continued downward motion
During, be not in too fast because of unreeling, cause drawstring drawknot chaotic；Rotary digging mechanism contiguously face carry out operation when, second
Directive wheel touches travel switch, and travel switch control hoist engine stops unreeling, and rotary digging mechanism persistently carries out operation excavation, works as rotation
When digging machine structure digs out downwards part soil, rotary digging mechanism and sliding block continue to move downward tenses drawstring again, and second can be made again
Directive wheel compression spring turns over certain angle clockwise, and the second directive wheel is away from travel switch, and travel switch control hoist engine is again
Start to unreel, continuous this motion, so as to ensure that rotary digging mechanism during lasting excavation, reasonably controls rotary digging mechanism
With the lifting of sliding block；After excavation terminates, control hoist engine is rotated clockwise, so as to wind drawstring, drives rotary digging mechanism and cunning
Block is moved upwards on slideway, is returned to initial position and is completed excavation.
Travel switch selects microswitch type, the travel switch of microswitch type can be accurately controlled the startup of hoist engine with
Close, improve the validity of device.
Drawstring selects round-strand rope, and the wear-resisting resistance to drawing of round-strand rope can be improved with the overall service life of extension fixture
The practicality of device.
Rotary digging mechanism, travel switch and hoist engine are art prior art, and attachment structure is mature technology, herein not
Repeat again.
(3) beneficial effect
Compared with prior art, overcoming the lowering or hoisting gear of Spiral digging machine under prior art can not automatically adjust the utility model,
Easily occur unreeling too fast, to cause drawstring drawknot chaotic shortcoming, pull drawstring to drive rotary digging mechanism in slideway by hoist engine
Upper motion, and the second directive wheel connecting spring by being hinged, and opened and closed using travel switch control hoist engine, so that
It is automatic realize the steady and continuous lifting of rotary digging mechanism while, reached be not in unreel it is too fast, it is therefore prevented that drawstring drawknot is mixed
Random effect, and it is very beneficial for the intermittent exercise of digging operation, transport the utility model by rational device layout
Row gets up simple efficient, with very strong practicality, is adapted to promote the use of.
