Abstract

The utility model relates to a full automatic hydraulic pedestal and reaming machine comprising a hydraulic cylinder the travel rod of which is provided with a piston. The top of the cylinder body is firmly connected with a hang pole, and a shaft which is firmly connected with the bottom part of the travel pole is fixed to a plurality of blade guide tracks. Each piece of the blade is hinged to the bottom of an oil cylinder through moving blade union screws, and the middle and upper part of each blade is provided with a blade hinge seat which is provided with a blade guide wheel. The guide wheel and the blade guide track form a kinematic pair, and the blade guide track is connected with a resetting device bottom plate through a firm connecting rod, while a resetting device connecting rod is arranged among the bottom of the blade, the resetting device bottom plate and the blade guide track. The utility model solves the problem that the existing reaming device can not process out the dimensions according to the design requirements, can not enlarge the pedestal, and has narrow application field.

Description

Full automatic hydraulic staving press

The utility model relates to a kind of pile spreader device that enlarges the bottom of stake or enlarge pile body along pile body length any part.

Enlarge the bottom of stake or the diameter of any part and can improve the supporting capacity of stake significantly, the bottom of therefore reaming in building operations, expansion stake is a necessary operation, at present, reaming, expanded bore pile generally have so several modes: 1, manually digging hole expanded bore pile, this stake danger in work progress is very big, and operator's life is subjected to prestige and helps, and not only construction speed is also very slow, and can only under specific geological conditions, just can use 2, with mechanical rotary cutting reaming stake.This equipment is to utilize the principle of lathe uprightly to rotate by hand control, the problem that this equipment exists is: a, can not expand the end, because the soil under the cutting need take out, place and connect earthenware at the bottom of stake, must leaving an enough segment distance like this, therefore do not reach the purpose of real reaming.B, actual stake type and the designing requirement that processes are variant.Because the operator is that the physical dimension that expands the every hole of stake type that like this is all inconsistent with the sensation operation, and owing to the hole that processes also can't be checked at deep under ground.The unreasonable maximum gauge of the shape of c, reaming place so just can not make the material that drops into after the reaming all bring into play its supporting capacity not in the bottom.D, reaming time are slow, hole quality is poor, and operator's labour intensity is big.To use this reaming equipment be rig bores light with straight hole and unloads drilling tool and re-assembly Counterboring apparatus, and the manpower slower soil of cutting of rotation that pressurizes is gradually realized reaming.E, the adaptation of geology level there is certain scope,, moulds layer then pore-forming difficulty or pore-forming not firmly as layer of sand.

The utility model task is: the staving press that can enlarge the hydraulic pressure full-automatic concrete castinplace pile of pile body any part at the bottom of a kind of can enlarge again is provided.

Task of the present utility model realizes as follows: hydraulic pressure automatically expands end staving press and comprises a hydraulic cylinder, the top is a piston on the hydraulic cylinder travel bar, the top is fixed with suspension rod on the cylinder body, be fixed with several pieces blade guide rails on the axle that bottom stroke lever, is connected mutually, every blade all is hinged on the bottom of oil cylinder by the moving vane connecting screw, the position, middle and upper part of every blade all is equipped with the blade hinge seat, the blade directive wheel is installed on it, directive wheel and blade guide rail constitute kinematic pair, on the blade guide rail, be connected with playback and use base plate, the device connecting rod that playbacks is installed with playbacking between base plate and the blade guide rail in the bottom of blade by the bar that is connected.

The operating principle of this device is: highly pressurised liquid enters high-voltage oil liquid accumulation of energy service depot 4 from oil inlet pipe 2, thereby promotion hydraulic pressure top stroke lever 6 moves downward on the axle that is connected mutually with the stroke lever bottom and is fixed with several pieces blade guide rail 10 movement therewith, promote the blade spreading by the guide wheel on the blade, realize the purpose of reaming, when reaching predetermined displacement, stop 7 will cut out automatically, reaming is finished, highly pressurised liquid is drawn back fuel tank by oil return pipe 3, stroke lever drive blade guide rail moves upward and by the playback device blades withdraw is resetted like this, stop cuts out automatically, once fulfils assignment.

The utility model is owing to adopt the operation of hydraulic pressure Automatic Control; whole device just 1 people operation; personal safety is not had any prestige to be helped; need not change drilling tool owing to use the utility model; reaming does not need outwards to fetch earth; but be power with the bottom outlet of soil extruding becoming designing requirement with high hydraulic pressure; the geometry of end stake; therefore reaming speed is fast; save time 150 times than mechanical hole reaming; owing to adopt hydraulic control to guarantee the physical dimension of reaming; do not reach desired physical dimension; equipment is not shut down; therefore reaming quality height of the present utility model, and expand the geometry that and accomplish rational in infrastructurely according to designing requirement, the earth volume that increases after the reaming can be given full play to the effect of bearing capacity; stress is good, and can save a large amount of raw material.Because the utility model work is to realize reaming therefore to the wide adaptability of geology in the mode with soil extruding, except that rock class geology, it also can be used in cohesive soil, sandy soil, in, geology level such as thick, gravel.Because the size in reaming footpath is controlled by stop, so the utility model can be chosen new counter bore diameter arbitrarily in addition.

Fig. 2 is the blade view.

Fig. 3 is a hydraulic control schematic diagram of the present utility model.

A most preferred embodiment of the present utility model, as figure, staving press comprises a hydraulic cylinder 5, the top is piston on the stroke lever 6 in it, on the cylinder body top be fixed with suspension rod 1 its effect be block suspension rod make it can be in the hole degree of depth lifting arbitrarily, be fixed with several pieces blade guide rails 10 on the axle that bottom stroke lever, is connected mutually, the utility model is selected 6 for use, this guide rail be shaped as wedge, the angle that changes blade by moving downward of wedge is carried out reaming, blade 11 is hinged on the bottom of oil cylinder 5 by the moving vane connecting screw, the position, middle and upper part of every blade all is equipped with the blade hinge seat, on hinge seat, be hinged with blade directive wheel 9, this directive wheel and blade guide rail 10 constitute kinematic pair, on the blade guide rail, be connected with playback base plate 15 by the bar 12 that is connected, the guide peg 13 of hydraulic pressure top stroke lever is installed between the bottom of blade and playback base plate and blade guide rail, on the upper top cover of oil cylinder, have oil inlet pipe 2, its effect is to make the hydraulic oil in the high-pressure pump enter cylinder body, oil return pipe 3, its effect is when oil return pipe work finishes playback oil to be drawn back in the fuel tank, oil cylinder is provided with range limiter 7, and its effect is to select desired counter bore diameter in the reaming scope that limits arbitrarily.
