It is expanding, and the soil in some cities has multiple supporting courses, can not be made for these different supporting course existing equipments.
Utility model content
The purpose of this utility model is to overcome the shortcomings of above-mentioned technology, and provides a kind of reaming tool, can be to difference
Supporting course carries out expanding.
The utility model to achieve the above object, using following technical scheme：
A kind of reaming tool, it is characterised in that：Including drilling rod, first connecting rod, second connecting rod, third connecting rod, fourth link
And pull rope, the front end of the drilling rod carry drill bit, the front portion of the drilling rod is provided with a diameter and is less than consolidating for bit diameter
Fixed set and movable sleeve, the fixed cover are located at the top of the movable sleeve, and the fixed cover is fixed on the drilling rod, the work
Dynamic set slides up and down cooperation with the drilling rod, is cut with scissors respectively with one end of first connecting rod and second connecting rod around the movable sleeve
Connect, one end of the other end of the first connecting rod and the third connecting rod is hinged, the other end of the second connecting rod and described the
One end of double leval jib is hinged, and the other end of the third connecting rod and fourth link is hinged with the fixed cover respectively, the traction
One end of rope is connected with the movable sleeve, and the other end goes out outside well deeply.Relative to prior art, the present apparatus is all to use existing brill
Machine and drilling rod, cost are low, it is only necessary to a present apparatus are installed in the top of drill bit, the present apparatus is merged in drilling rod when not working
Around, due to being relatively large in diameter so normal drill does not interfere with the present apparatus for drill bit, when going into the well, drill bit first drills out one
Elongated hole, when getting into supporting course, drive pull rope to make pull rope drive movable sleeve to move up by equipment, utilize double leval jib
Principle so that four connecting rods open, and carry out cutting to supporting course using four connecting rods and reach expanding purpose, can by the present apparatus
It is expanding to be carried out to different supporting courses, so as to improve the fastness of concrete-pile.
Preferably, the surface of the drilling rod is provided with guide rail, and the guide rail coordinates with the guide groove on the inside of the movable sleeve.This
Sample can prevent movable sleeve from being rotated along drilling rod.
The beneficial effects of the utility model are:The present apparatus is all to use existing rig and drilling rod, and cost is low, it is only necessary to
A present apparatus is installed in the top of drill bit, and the present apparatus is merged around drilling rod when not working, due to the diameter of drill bit
It is larger so normal drill does not interfere with the present apparatus, when going into the well, drill bit first drills out an elongated hole, when getting into supporting course, passes through
Equipment drives pull rope to make pull rope drive movable sleeve to move up, and utilizes the principle of double leval jib so that four connecting rods open, profit
Cutting is carried out to supporting course with four connecting rods and reaches expanding purpose, different supporting courses can be expanded by the present apparatus
Footpath, so as to improve the fastness of concrete-pile.
Brief description of the drawings
Fig. 1 is the structural representation of utility model works state；
Fig. 2 is the utility model non-operational state schematic diagram.
Embodiment
Below in conjunction with the accompanying drawings and preferred embodiment describes specific embodiment of the present utility model in detail.Such as Fig. 1 and Fig. 2 institutes
Show, a kind of reaming tool, including drilling rod 1, first connecting rod 2, second connecting rod 3, third connecting rod 4, fourth link 5 and pull rope 6,
The front end of the drilling rod carries drill bit 7, and the front portion of the drilling rod is provided with fixed cover 8 and activity that a diameter is less than bit diameter
Set 9, the fixed cover is located at the top of the movable sleeve, and the fixed cover is fixed on the drilling rod, the movable sleeve and institute
To state drilling rod and slide up and down cooperation, one end around the movable sleeve respectively with first connecting rod and second connecting rod is hinged, and described
One end of the other end of one connecting rod and the third connecting rod is hinged, the other end of the second connecting rod and the one of the fourth link
End is be hinged, and the other end of the third connecting rod and fourth link is hinged with the fixed cover respectively, one end of the pull rope with
The movable sleeve connection, the other end go out outside well deeply.In the present apparatus, four connecting rod positions are multiple, are arranged on fixed box set activity ring week
Around set, connecting rod is more, and reaming ability is stronger, and the present apparatus is all to use existing rig and drilling rod, and cost is low, it is only necessary to
A present apparatus is installed in the top of drill bit, and the present apparatus is merged around drilling rod when not working, due to the diameter of drill bit
It is larger so normal drill does not interfere with the present apparatus, when going into the well, drill bit first drills out an elongated hole, when getting into supporting course, passes through
Equipment drives pull rope to make pull rope drive movable sleeve to move up, and utilizes the principle of double leval jib so that four connecting rods open, profit
Cutting is carried out to supporting course with four connecting rods and reaches expanding purpose, different supporting courses can be expanded by the present apparatus
Footpath, so as to improve the fastness of concrete-pile.
In order to prevent that movable sleeve rotates during four link rotatables, the surface of the drilling rod is provided with guide rail 10,
The guide rail coordinates with the guide groove on the inside of the movable sleeve.Can so it prevent movable sleeve from being rotated along drilling rod.
The present apparatus is all to use existing rig and drilling rod, and cost is low, it is only necessary to installs this dress in the top of drill bit
Put, the present apparatus is merged around drilling rod when not working, due to being relatively large in diameter so normal drill will not shadow for drill bit
The present apparatus is rung, drill bit first drills out an elongated hole when going into the well, and when getting into supporting course, drives pull rope to make pull rope by equipment
Drive movable sleeve to move up, utilize the principle of double leval jib so that four connecting rods are opened, and supporting course is carried out using four connecting rods
Cutting reaches expanding purpose, can be expanding to different supporting course progress by the present apparatus, so as to improve the jail of concrete-pile
Solidity.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
