Abstract

The utility model relates to discard stake extracting apparatus technical field, more particularly to a kind of discarded stake pull-up, including sleeve and the device of setting one's teeth on edge being arranged in sleeve, the internal diameter of the sleeve is greater than the outer diameter of discarded stake, the device of setting one's teeth on edge includes several pieces and sets one's teeth on edge and spring, it is described set one's teeth on edge be mounted in the groove of the sleeve bottom, the front set one's teeth on edge tilts down, and the spring is arranged between the rear portion set one's teeth on edge and sleeve.Present apparatus structure is simple, discarded pile protection is lived by the present apparatus, the present apparatus and discarded stake are exerted a force together again, the strength in the discarded stake of a part can thus be reduced, so as to effectively prevent discarding the case where stake is broken during pile pulling, at low cost filling using the present apparatus, form of construction work is simple.

Description

Discarded stake pull-up
Technical field
The utility model relates to discarded stake extracting apparatus technical field more particularly to a kind of discarded stake pull-ups.
Background technique
The full circle swinging engineering method obstacle cleaning machine of usual pile pulling or water jetting pile pulling need that the soil removal of surrounding can be extracted Discarded stake, this two kinds of construction technologies all need large-scale special equipment of marching into the arena, and only special equipment is just very high into fee for showing up, construction cost Higher, when especially for only needing to pull out a small amount of several abolishment pile foundations, often equipment is just significantly larger than practice of construction into fee for showing up Cost.In addition, be very easy to cause discarded stake fracture during existing mode pile pulling, if the discarded stake fracture later period again into Construction will be extremely difficult if row pile pulling, needs with excavator to breaking part, can dig in some cases very depth can Fracture position is found, undoubtedly increases construction cost again.
Utility model content
Purpose of the utility model is to overcome the shortcomings of the above technology, and to provide a kind of discarded stake pull-ups.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of discarded stake pull-up, it is characterised in that: described including sleeve and the device of setting one's teeth on edge being arranged in sleeve The internal diameter of sleeve is greater than the outer diameter of discarded stake, and the device of setting one's teeth on edge includes several pieces and sets one's teeth on edge and spring, it is described set one's teeth on edge be mounted on In the groove of the sleeve bottom, the front set one's teeth on edge is tilted down, and the spring is arranged between the rear portion set one's teeth on edge and sleeve.
Described to set one's teeth on edge be four pieces, and front of setting one's teeth on edge surrounds round or rectangular.
The top of the sleeve has lifting lug.
The beneficial effects of the utility model are: compared with the existing technology, present apparatus structure is simple, will be discarded by the present apparatus Pile protection is lived, then the present apparatus and discarded stake are exerted a force together, can thus reduce the strength in the discarded stake of a part, so as to It effectively prevent discarding the case where stake is broken during pile pulling, at low cost filling using the present apparatus, form of construction work is simple.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the cross-sectional view in the direction A-A in Fig. 1;
Fig. 3 is the cross-sectional view of the direction A-A another kind structure in Fig. 1;
Fig. 4 is the application schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment of the present utility model is described in detail in preferred embodiment.As shown in Figure 1, one The discarded stake pull-up of kind, including sleeve 1 and the device of setting one's teeth on edge being arranged in sleeve, the internal diameter of the sleeve is greater than discarded stake Outer diameter, the device of setting one's teeth on edge includes several pieces of set one's teeth on edge 2 and springs 3, it is described set one's teeth on edge be mounted on the groove 4 of the sleeve bottom Interior, the front set one's teeth on edge tilts down, and the spring is arranged between the rear portion set one's teeth on edge and sleeve.
As shown in Figures 2 and 3, described to set one's teeth on edge be four pieces, and front of setting one's teeth on edge surrounds round or rectangular.
For the ease of hanging moving sleeve, lifting lug 5 is had at the top of the sleeve.
As shown in figure 4, in use, first determining the exact position of discarded stake;Several strength holes are bored around discarded stake again, Make in its hole full of mud;Discarded stake pull-up is covered on the discarded village, sleeve is pressed into or rotates into soil layer, mainly By the way of vibration or other modes, in sleeve decentralization process, sets one's teeth on edge and overcome the pressure of spring, to that can shrink, set one's teeth on edge the beginning The surface of this discarded stake is touched in terminating.After the bottom of sleeve is lowered into designated position, sleeve is above mentioned, this process is above mentioned using crane Sleeve and discarded stake, during mentioning on sleeve, due to setting one's teeth on edge, front is tilted down, and sleeve bottom sets one's teeth on edge when mentioning above Meeting clamping is discarded around stake;It is last to propose sleeve and discarded stake simultaneously.
Present apparatus structure is simple, is lived discarded pile protection by the present apparatus, then the present apparatus and discarded stake are exerted a force together, in this way The strength in the discarded stake of a part can be reduced, so as to effectively prevent the case where discarding stake fracture during pile pulling hair Raw, at low cost filling using the present apparatus, form of construction work is simple.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
