After the utility model is realized, the utility model has the advantages of high work efficiency, low operating cost, etc. as compared with the prior art.

Description

A kind of portable rig

The utility model relates to a kind of rig, exactly is a kind of portable rig that is applicable to field work.

At present, the portable rig that uses in people's operation in the open air is the dc-battery electric drill, and the subject matter that this rig in use exists is: 1, power is little, and rotating speed is low, thereby operating efficiency is lower; 2, change one-shot battery, only can work 1-3 hour, the time of continuous operation is shorter, and cost of use is higher.

The purpose of this utility model is to provide the portable rig that a kind of power is big, rotating speed is high, stream time is long, cost of use is lower for people.

The purpose of this utility model is achieved in that its flexible axle assembly 2 by backpack gasoline engine 1 and adapted thereof, and wellbore part 3 is formed; This wellbore part mainly is made up of handgrip sleeve pipe 9, axle 8, drill bit clamp 11, shaft coupling 6, flexible axle fixed cover 5, fixture 4; Be hinged in the endoporus of handgrip sleeve pipe axle 8 axial no plaies, fixed installation drill bit clamp 11 on the one external part, fixed installation shaft coupling 6 on another external part is provided with fixture 4 on the grip cover tube end fixed installation flexible axle fixed cover 5 of this end one side, this fixed cover; Wellbore part passes through described shaft coupling, the flexible axle fixed cover, and fixture connects with the clutch end of described flexible axle assembly.

Compared with the prior art the utility model has the following advantages after realizing: 1, power is big, rotating speed is fast, thereby operating efficiency is higher; 2, stream time is long, and cost of use is also lower.

Below in conjunction with accompanying drawing embodiment of the present utility model is done explanation in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the version schematic diagram of wellbore part.

Fig. 3 is flexible axle assembly and wellbore part connecting relation schematic diagram.

As seen from the figure, the utility model is made up of backpack gasoline engine 1, flexible axle assembly 2, wellbore part 3.Wherein, the flexible axle assembly of backpack gasoline engine and adapted thereof is selected same each parts that use in market BG305 on sale or the BG415 type brush cutter for use, 3 of wellbore parts are manufactured by Fig. 2, as shown in Figure 2, wellbore part is made up of handgrip sleeve pipe 9, axle 8, bearing 7, end cap 10, drill bit clamp 11, shaft coupling 6, flexible axle fixed cover 5, fixture 4.Wherein, axle 8 is articulated in the grip cover pipe orifice by bearing 7, and an one external part promptly illustrates right-hand end and makes the cone table shape, and this cone table is inserted in the afterbody taper hole of drill bit clamp 11 of standard, make spools 8 and the drill bit clamp between realize being fixedly connected; Its another external part promptly illustrates thread connection between left end and the shaft coupling, and by threaded connection mode fixed installation flexible axle fixed cover 5, the other end of handgrip sleeve pipe is installed end cap 10 at the grip cover tube end of this end one side; In the outer end of flexible axle fixed cover, promptly illustrate a jackscrew is installed on the left end one side pipe wall, this jackscrew constitutes fixture 4.

During general assembly, an end of flexible axle assembly connects with the power output shaft of backpack gasoline engine, and connecting mode is same as the prior art; Its other end and wellbore part left end plug, the prism shape connector 15 of its driving snake 13 ends is inserted in the endoporus of shaft coupling 6, and the hardware positioning sleeve 14 that makes its cannula tip inserts in the endoporus of flexible axle fixed covers 5, and then, by fixture 4 both being fixedly connected gets final product.

During use, can be according to need of work, the unit-type drill head 12 of corresponding specification is stuck on the drill bit clamp 11, then, start gasoline engine, can drop into boring work.
