Abstract
The utility model relates to construction machinery, in particular to a static force pile drawing machine which comprises a base, multi-stage flexible hydraulic cylinders, a cross beam, concave tracks, a sliding block and a pile clamping device, wherein the base is connected with the cross beam through four multi-stage flexible hydraulic cylinders; the two crossed concave tracks are arranged onthe bottom surface of the cross beam; the sliding block slides in the concave tracks, and is connected with the pile clamping device through a steel wire rope. When a pile is not in the center of the pile-drawing machine and the sliding block slides in the concave tracks under the action of a tension, an additional bending moment which is harm to the multi-stage hydraulic cylinders does not generated.
Description
Technical field:
The utility model relates to a kind of building machinery, particularly a kind of static pile drawer.
Technical background:
Extractor is that a kind of for working the building machinery that pulls out building ruins king-pile, H shaped steel etc., static pile drawer generally includes base, crossbeam, pile chuck and two and above hydraulic cylinder, and hydraulic cylinder and base and crossbeam are gun iron link.Hydraulic cylinder pulling force is larger, and stroke is longer, in the time that static pile drawer can not keep level or stake not at extractor center position, can produce a larger additional bending moment to hydraulic cylinder, and hydraulic cylinder is damaged too early.
Utility model content:
The utility model is intended to solve when static pile drawer is out-of-level or during not at static pile drawer center position, the flimsy problem of hydraulic cylinder.
For addressing the above problem, the utility model has been taked following scheme:
A kind of static pile drawer, comprise base, multi-stage expansion hydraulic cylinder, crossbeam, concave tracks, slide block and pile chuck, it is characterized in that described base is connected by four multi-stage expansion hydraulic cylinders with crossbeam, crossbeam bottom surface is provided with two concave tracks, slide block is walked in concave tracks, and slide block is connected by wire rope with pile chuck.
Two described concave tracks interconnections can be walked slide block in two concave tracks.
Described slide block is circular, and round slider can more easily enter a new line in two concave tracks.
The utlity model has following outstanding advantages:
Static pile drawer of the present utility model can make pile chuck move along two concave tracks directions, thereby additional bending moment is reduced or disappear, and extends hydraulic cylinder application life.
Brief description of the drawings:
Fig. 1 is schematic diagram of the present utility model, the sectional view that Fig. 2 is crossbeam, and Fig. 3 is slide block and pile chuck connection diagram.
In figure, 1 is base, and 2 is multi-stage expansion hydraulic cylinder, and 3 is crossbeam, and 4 is wire rope, and 5 is pile chuck, and 6 is stake, and 7 is controller, and 8 is concave tracks, and 9 is slide block.
Detailed description of the invention:
As shown in the figure, static pile drawer of the present utility model comprises base, multi-stage expansion hydraulic cylinder, crossbeam, controller, slide block and pile chuck, crossbeam and base are by the support and connection of four multi-stage expansion hydraulic cylinders, crossbeam bottom surface is provided with two concave tracks, pile chuck is connected with slide block by wire rope, slide block slides in concave tracks, article two, concave tracks interconnection, slide block can be entered a new line in two concave tracks, slide block is circular, it is easier when slide block is entered a new line in two tracks, four multi-stage expansion hydraulic cylinders are connected with controller with pile chuck, the clip pile action of controller control pile chuck and the expanding-contracting action of four multi-stage expansion hydraulic cylinders.
When work, controller control pile chuck clamps stake, controller is given an order, four multi-stage expansion hydraulic cylinders extend, and static pile drawer produces pulling force to stake, under the effect of pulling force, slide block is walked automatically in concave tracks, make the additional bending moment minimum producing, four multi-stage expansion hydraulic cylinders continue to extend, and stake is pulled out.
