Aiming to achieve the effect, the adjustable pile extractor comprises a pull rod inserted in a pull rod sleeve pipe; the pull rod sleeve pipe is connected with a fixed clamping claw; a movable clamping claw is movably mounted on the fixed clamping claw; and the part between the fixed clamping claw and the movable clamping claw is tightly compressed by a screw. As the technical scheme is adopted, a user can clamp the piles needing to be extracted through callipers formed by the movable clamping claw and the fixed clamping claw together, and then extract the piles through the pull rod inserted in the pull rod sleeve pipe, so as to achieve the effect of pile extraction. The whole structure is small, exquisite, simple and convenient, and the pile extractor is convenient to use and is applicable to ordinary families.
Description
Technical field
The utility model relates to a kind of useless stake and extracts equipment, relates in particular to a kind of adjustable pile extractor.
Background technology
Extractor is a kind of special equipment, is used for pulling out of useless stake.In the extractor of the prior art, be the extractor that maximizes mostly, generally be used to build stake pulling out as cement, reinforcing bar, and it is less at the pile extractor of the little timber that uses in the gardening, steel pipe pile, bamboo stake etc., as if is a kind of equipment that is used to pull out bamboo stake in a row as Shanghai City the 4th building Co., Ltd in utility model patent " the bamboo raft dowel pile pulling cage " patent No. 200720069039.4 of in April, 2007 application, look to be applicable to that the stub in the gardening pulls out.But problem such as the related product of this patent still will be used with big machinery, has brought the cost height simultaneously, and volume is big does not reach simple, light requirement by analysis.Some pile extractor has accomplished that also structure is small and exquisite, and is easy to carry, but fails to satisfy in the gardening characteristics that will adjust flexibly according to the size of stake.How to design domestic type extractor a kind of simple in structure, easy to use, moderate and just become the problem that people are concerned about.
The utility model content
The purpose of this utility model provides a kind of adjustable pile extractor, and structure is small and exquisite simple, and is easy to carry, can adjust flexibly according to the size of stake, is applicable to average family.And the stake of extracting can be crooked, damages, and can reuse.
For reaching described effect, a kind of adjustable pile extractor comprises pull bar, and pull bar is inserted on the pull bar sleeve, and the pull bar sleeve connects decides claw, decides on the claw activity moving claw is housed, and decides to form clamp with screw in compression between claw and the moving claw.
Preferably, describedly decide that a straight trough is arranged in the claw, moving claw is a T type spare, and moving claw inserts in the straight trough and can move in deciding the straight trough of claw, after moving claw moves to correct position, by screw in compression claw is pressed abd fixed on and decides on the claw.The user can adjust two distances between the claw according to the diameter of the required stake of pulling out like this.
Preferably, described pull bar sleeve is provided with a cylinder, and the pull bar sleeve is plugged on by cylinder to be decided in the claw, has cannelure on the cylinder, be fixed on the latch of deciding claw and insert in the cannelure, such structure pull bar sleeve can not move axially with deciding can do between the claw radially rotation.Because after deciding clamp that claw and moving claw form stake being blocked, angle between clamp and the stake can not change, and pull bar continues to produce corner, the rotation of pull bar sleeve and clamp adapts to this angular relationship, to guarantee that clamp can not bend pile body and damage, guaranteed reusing of the stake that pulls up.
Preferably, describedly decide to be equipped with frictional layer on claw and the moving claw acting surface.Such structure improves the friction area between claw and institute's pile pulling, increases frictional force, avoids skidding in withdrawal process.
Preferably, described pull bar is the pipe fitting for 26 millimeters of diameters, and the pipe fitting of specification is the standard pipe fitting like this.Owing to have the pipe that is scattered, stake etc. in the place of construction, therefore after definite this point, the user can adopt the ready-made stake of construction plant as pull bar fully, and needn't additionally add an independent pull bar.Such structure has guaranteed the small and exquisite of pile extractor integral body, has saved Product transport and the space of carrying.
Owing to adopted described technical scheme, the user can block the stake that need extract by deciding the clamp that claw and moving claw form, then by the pull bar that is inserted in the pull bar sleeve is extracted stake the effect that reaches pile pulling.Total is small and exquisite easy, and is easy to use, is fit to average family and uses.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the overall structure schematic diagram of a kind of pile extractor of the utility model.
Fig. 2 is the moving claw structure schematic diagram of a kind of pile extractor of the utility model.
Fig. 3 be a kind of pile extractor of the utility model decide the claw structure schematic diagram.
Fig. 4 is the user mode schematic diagram of a kind of pile extractor of the utility model.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of pile extractor comprises pull bar 1, and pull bar 1 is inserted on the pull bar sleeve 2, pull bar sleeve 2 with decide claw 3 and link, decide to be equipped with on the claw 3 and move claw 4, decide to compress the formation clamp with screw 5 between claw 3 and the moving claw 4.
Describedly decide that a straight trough 31 is arranged on the claw 3, moving claw 4 be a T shape part, and moving claw 4 can move in straight trough 31, compresses with screw 5 when moving to correct position, decides the openings of sizes of the clamp jaw that claw 3 and moving claw 4 formed.
The described acting surface of deciding claw 3 and moving claw 4 is provided with frictional layer 32, to improve the frictional force between claw and the stake.When just being meant work, decides the acting surface of deciding claw 3 and moving claw 4 that part that claw 3 and moving claw 4 contact with the institute pile pulling.
On the described pull bar sleeve 2 with a cylinder 21 with decide claw 3 inside and link, have cannelure 22 on the cylinder 21, be fixed on the latch decided on the claw 36 and insert in the cannelures 22, such structure pull bar sleeve 2 can not move axially with deciding can do between the claw 3 radially rotation.
When using as shown in Figure 4, adapt deciding the diameter that openings of sizes between claw 3 and the moving claw 4 adjusts to institute pile pulling.Its method is to be pressed onto the required stake that pulls up one side earlier with deciding claw 3, regulates moving claw 4 then to compressing the stake opposite side, will move claw 4 with screw 5 and fix.
Then will pull bar 1 insert in the sleeve 2 and arrive ground up to an end, and be fulcrum with ground, the hand-held other end of user upwards firmly relies on the frictional force between clip 2 and institute's pile pulling, easily stake is extracted.Because between described pull bar sleeve 2 and the pull bar 1, pull bar sleeve 2 and decide all can rotate between the claw 3, therefore in the process of pile pulling, decide to have only frictional force between clamp that claw 3 and moving claw 4 formed and the institute's pile pulling body, decide the clamp that claw 3 and moving claw 4 form and can not make institute's pile pulling body produce damages such as bending, the stake of pulling out like this can reuse.
Because pull bar 1 adopts the standard pipe fitting of 26 millimeters of diameters.That is to say that the user can adopt the stake of job site directly to use, such design is not easy to use carrying of person on the one hand, can reduce the packaging volume of product on the other hand, reduces the Product transport expense.
The above only is a specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and variation of being done or modification all are encompassed among the claim of the present utility model.
