Description
Technical field
The utility model is related to the construction machinery installation tool for carrying out pore-forming operation in building pile foundation engineering, more particularly to
A kind of servicing unit that installs for long drill bit.
Background technology
Churning driven is to carry out one of construction machinery of pore-forming operation in building pile foundation engineering, has been widely used at present each
Plant in Grouting Pile Engineering of Drilling Hole construction.With the continuous development of China's economic construction level, super-high buildings and overlength bridge are not
Break and emerge in large numbers the also more and more higher of the requirement to pile foundation engineering, 2 meters～4 meters design stakes for being increasingly becoming tall and big bridge main tower pile foundation
Footpath, while in order to ensure that the perpendicularity in churning driven boring procedure, the long drill bit of some more than 3m are also progressively applied.With
As a example by domestic big-and-middle-sized rotary drilling rig south car TR460D, churning driven mast is limited to, the drill bit that more than 2.5 meters of diameter is pacified on level land
Dress height at most allows 2.2m, and therefore drill bit of the height more than 2.2m just should not be installed on level land.
Utility model content
For technical problem present in prior art, the utility model provides a kind of auxiliary dress that installs for long drill bit
Put, the device both can ensure that the fastness that long drill bit is installed, and improve again carries out the quality of pore-forming using long drill bit, same to time delay
The long drill bit life-span.
In order to solve technical problem present in prior art, the utility model is adopted the following technical scheme that：
A kind of servicing unit that installs for long drill bit, is made up of device body, and described device body includes split type card
Seat and cutting ferrule, one side bottom of the deck are provided with draw-in groove, are provided with the snap arm with limiting section at the top of its opposite side；The draw-in groove
Recess at be provided with lagging, be provided with perpendicular baffle plate on the inside of the draw-in groove；The cutting ferrule is connected with the snap arm by its jack
Connect.
Suspension ring are additionally provided with the deck.
Reinforcement is additionally provided with the cutting ferrule.
The jack is arranged on the groove of the cutting ferrule center.
The draw-in groove is hook recess.
The limiting section is vertically set on one side of the snap arm.
Between the two-arm of the snap arm, angle is more than 90 °.
The utility model beneficial effect：
First, the utility model is by the draw-in groove on deck, drill bit casing is firmly connected by baffle plate anyhow；Simultaneously
The snap arm being plugged into by the jack of cutting ferrule on deck, drill bit, casing are organically combined into one, and solve traditional long drill bit
Installation difficulty, the technical barrier of fastness difference after installation.
Second, the utility model can be according to the size of the long drill bit of job site by the limiting section being arranged on deck
Needs are adjusted, and the design of the limiting section makes the utility model be suitable for the long drill bit of various sizes, meets modern architecture industry fast
The needs of speed development.
3rd, the utility model deck, cutting ferrule split-type structural, convenient regulation whole device are improve with long drill bit
Rotary drilling rig hole quality, extends bit life.
4th, the utility model designs ingenious, simple to operate, energy-conserving and environment-protective, with low cost.
Description of the drawings
Fig. 1 is a kind of assistant apparatus structure schematic diagram that installs for long drill bit of the utility model.
Reference
1 deck, 11 draw-in groove, 12 limiting section, 13 snap arm, 14 lagging 15 erects baffle plate

Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of servicing unit that installs for long drill bit of the utility model, is made up of device body, described
Device body includes that split type deck 1 and cutting ferrule 2,1 one side bottom of the deck are provided with draw-in groove 11, and the draw-in groove 11 is hook-type
Groove.The snap arm 13 with limiting section 12 is provided with the top of its opposite side；The limiting section 12 is vertically set on the snap arm 13
On one side.Length of the length of the limiting section 12 less than any one side in the snap arm 13.Between the both sides of the snap arm 13
Angle is more than 90 °.Lagging 14 is provided with the recess of the draw-in groove 11, is provided with perpendicular baffle plate 15 on the inside of the draw-in groove 11；This
Baffle plate 15 being erected described in utility model and being shaped as triangle, which connects radian on the inside of the radian and drill bit casing of casing cutting
Unanimously.The cutting ferrule 2 is connected with the snap arm 13 by its jack 21.Suspension ring 16 are additionally provided with the deck 1.
As shown in figure 1, being additionally provided with reinforcement 22 on the cutting ferrule 2.Reinforcement 22 described in the utility model adopts right angle
Triangular steel plate.The jack 21 is the groove for being arranged on 2 center of the cutting ferrule.
The utility model work progress：
First, draw-in groove in the utility model is inserted behind the edge of drill bit casing, on fluted tail and the casing side of draw-in groove
The junction welding lagging of edge；Meanwhile, in draw-in groove another side and the perpendicular baffle plate of the junction welding at casing edge.Now, originally
In utility model, deck is connected with casing securely.
Second, start crane drill bit is hung in people's casing, while the jack of cutting ferrule is penetrated in the snap arm in deck, according to
The requirement of practice of construction, adjustment are fastened in the position of snap arm, after determination weld cutting ferrule bottom with drill bit, then the cutting ferrule back side with
Reinforcement is welded between drill bit.
