Abstract
The utility model discloses a pile holding mechanism suitable for H-shaped steel. The utility model is composed of a hydraulic cylinder, a mouth of tongs, a return spring, and a pipe holding box, the inside of the pipe holding box (5) is a hollow cylinder, four clipping devices which are axially symmetrical in pairs, and the clipping devices axially symmetrical in pairs are mutually vertical, and corresponds respectively to the two vertical and horizontal surfaces corresponding to the H-shaped steel (8); the structure of the clipping device is that a mouth of the tongs (2) is arranged in the guiding groove of the pipe holding box (5), and two upper and lower cone-shaped pipe holding blocks (3) which are relevant to the mouth of the tongs (2) and arranged between the mouth of the tongs (2) and the pipe holding box (5) and are respectively fixedly connected with the piston rod of the hydraulic cylinder (1) arranged on the pipe holding box (5); a return spring (4) is arranged between the mouth of the tongs (2) and the pipe holding box (5). The utility model is a pipe holding mechanism suitable to the pile holding of the H-shaped steel, the processing and manufacture are easy, the operation and use are convenient, the work is secure and reliable, and the repair and maintenance are convenient.
Description
Technical field:
The utility model relates to a kind of engineering machinery, particularly relates to a kind of building operations basis pile press Pile holding mechanism.
Technical background:
Existing hydraulic static pile pressing machine, have low noise, shockproof, pollution-free, efficiency of construction is high and can effectively reduce the requirement of pile tube compressive strength, adapt to the characteristics of thin-wall pipe pile construction and come into one's own day by day.The Pile holding mechanism of existing hydraulic static pile pressing machine can be applied to prefabricated tubular pile, but can not be applicable to the H shape steel that application is extremely wide, and range of application is subjected to severely restricts, has seriously restricted this and has had the popularization of the construction equipment of clear superiority.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind ofly can be applicable to that the folder stake of H shape steel and reasonable in design, processing and manufacturing are easy, easy for operation, safe and reliable, maintain Pile holding mechanism easily.
The technical solution adopted in the utility model is: Pile holding mechanism is made up of hydraulic cylinder, jaw, folder stake piece, back-moving spring, pile clamping box, pile clamping box inside is hollow cylinder, in its hollow cylinder, be provided with four axially symmetrical in twos clamping devices, and two groups axially the clamping devices of symmetry are orthogonal in twos, correspond respectively to two of H shape steel faces in length and breadth; The clamping device structure is: be provided with jaw in the gathering sill of pile clamping box, be provided with corresponding and two tapered clamp stake pieces up and down that be connected with the piston rod of being located at the hydraulic cylinder on the pile clamping box respectively with jaw between jaw and pile clamping box casing; Between jaw and pile clamping box casing, be provided with back-moving spring.
The utility model is provided with in twos axially four clamping devices of symmetry owing to adopted technique scheme in the pile clamping box hollow cylinder, and two groups axially the clamping devices of symmetry are orthogonal in twos, correspond respectively to two of H shape steel faces in length and breadth; Every stack clamping device structure is: be provided with jaw in the gathering sill of pile clamping box, be provided with corresponding and two tapered clamp stake pieces up and down that be connected with the piston rod of being located at the hydraulic cylinder on the pile clamping box respectively with jaw between jaw and pile clamping box casing; Between jaw and pile clamping box casing, be provided with back-moving spring; When the utility model carries out pressing pile construction, the piston rod of the clamping device hydraulic cylinder of two groups of symmetries promotes tapered clamp stake piece compressing jaw, make jaw clamp H shape steel from both direction, thereby hydraulic static pile pressing machine can be pressed into ground with H shape steel, after a pushing stroke is finished, the hydraulic cylinder backhaul promotes tapered clamp stake piece, and jaw automatically resets by the effect of back-moving spring, can carry out the next round operation again; Can make pile clamping box can adapt to the both direction in length and breadth of H shape steel by the orientation of transposing jaw in use, so the utility model is a kind ofly can be applicable to that the folder stake of H shape steel and reasonable in design, processing and manufacturing are easy, easy for operation, safe and reliable, maintain Pile holding mechanism easily.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure sectional view.
The specific embodiment:
Referring to Fig. 1 and Fig. 2, Pile holding mechanism is made up of hydraulic cylinder, jaw, folder stake piece, back-moving spring, pile clamping box, pile clamping box 5 inside are hollow cylinder, in its hollow cylinder, be provided with four axially symmetrical in twos clamping devices, and two groups axially the clamping devices of symmetry are orthogonal in twos, correspond respectively to two of H shape steel 8 faces in length and breadth; The clamping device structure is: be provided with jaw 2 in the gathering sill 9 of pile clamping box 5, be provided with corresponding and two tapered clamp stake pieces 3,6 up and down that be connected with the piston rod of being located at the hydraulic cylinder 1,7 on the pile clamping box 5 respectively with jaw 2 between jaw 2 and pile clamping box 5 casings; Between jaw 2 and pile clamping box 5 casings, be provided with back-moving spring 4.
When the utility model carries out pressing pile construction, the piston rod of the hydraulic cylinder 1,7 of the clamping device of two groups of symmetries promotes tapered clamp stake piece 3,6 compressing jaws 2, make jaw 2 clamp H shape steel 8 from both direction, thereby hydraulic static pile pressing machine can be pressed into ground with H shape steel 8, after a pushing stroke is finished, hydraulic cylinder 1,7 backhauls promote tapered clamp stake piece 3,6, and jaw 2 automatically resets by the effect of back-moving spring 4, can carry out the next round operation again; Can make pile clamping box 5 can adapt to the both direction in length and breadth of H shape steel 8 by the orientation of transposing jaw 2 in use.
