Abstract
The invention discloses a simple jacking device, comprising a hydraulic jack, a frame, a connecting plate, a pressure bearing shaft, a jacking pressure spring and a clamp, wherein the bottom of the hydraulic jack is fixed on the frame, and a hydraulic cylinder of the hydraulic jack is fixedly connected with the connecting plate; the connecting plate is provided with a rail groove for ensuring longitudinal motion of the pressure bearing shaft; the frame is provided with an annular rail groove, and the pressure bearing shaft moves along the annular rail groove under the propulsion of the connecting plate to realize clamping, push and return of the clamp; and the jacking pressure spring can push the pressure bearing shaft to enter a return rail when the pressure bearing shaft runs to a travel end. The simple jacking device is simple in manufacturing, low in cost and convenient to operate and carry, can accomplish laying of passing ground flat iron and through pipes without destroying roads or using large machinery, and is low in cost and simple in operation.
Description
Technical field
The invention belongs to mechanical field, be specifically related to a kind of simple and easy jacking device, all kinds of engineering can be applied to and pass by one's way ground connection band iron, the laying of poling.
Background technology
In engineering, ground network lay and pass by one's way cable installation in pipe need pre-buried before pavement construction prerequisite, ground connection band iron generally adopts-80*8, and poling of passing by one's way generally adopts DN50 or DN80 steel pipe.Due to reasons such as design, drawing changes, after often occurring in engineering that pavement construction completes, pre-buried ground connection band iron of passing by one's way under road, poling leak and lay or lay the situations such as positional fault, the built-in fittings such as ground connection band iron, poling are caused to use, need again to lay, but because road surface completes, can only take to destroy road surface, draw dig, the construction of the method such as push pipe.Take to destroy road surface, draw to dig and waste time and energy, while bringing direct economic loss, road pavement may cause the damage of unrepairable, and due to pipe pushing technology complicated, need big machinery, costly.
Summary of the invention
In order to solve the problem, the present invention has designed and produced a kind of simple and easy jacking device, simple with it, light and handy and effective structure, when not using external power source and destroying road surface, manually pushed up road surface by ground connection band iron or steel pipe (hereinafter referred to as object) easily.
The technical solution used in the present invention is: a kind of simple and easy jacking device, comprises hydraulic jack, frame, wins in succession, backup rolls, top pressure spring and fixture, and hydraulic jack top/bottom part is fixed in frame, and the hydraulic cylinder of hydraulic jack is fixedly connected with winning in succession; Have rail groove on winning in succession and ensure backup rolls lengthwise movement; Frame has circular orbit slot, and under the promotion of winning in succession, backup rolls is orbital motion annularly, realizes the clamping of fixture, pushes and return; Top pressure spring when last item moves to the stroke end, can promote last item and enters in return trajectory.
Further, described fixture can be changed, and its bayonet socket can be dull and stereotyped or semicircle, for clamping band iron or steel pipe.
Further, with rubber blanket on described fixture, for reducing the damage to band iron or steel pipe surface.
The beneficial effect that the present invention produces is: the present invention makes simple, with low cost, operate easy to carry, can when not destroying road surface, not using big machinery by the present invention, complete ground connection band iron of passing by one's way, the laying of poling, and with low cost, operate simple and easy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
A kind of simple and easy jacking device, comprises hydraulic jack 1, frame 2, wins 3 in succession, backup rolls 4, top pressure spring 5 and fixture 6.Hydraulic jack 1 fixes frame 2 end, and hydraulic jack 1 end 3 to be connected with winning in succession, wins in succession 3 to be fixed in frame 2 by backup rolls 4, and win in succession on 3 and have long rails groove, backup rolls 4 can vertically move along rail groove; Frame 2 also has rail groove, backup rolls 4 can move along rail groove simultaneously; Fixture 6 is fixed on backup rolls 4, can clamp object in backup rolls 4 motion process, and before send object.
During use, according to actual demands of engineering demand correct position, jacking device is fixed on ground or other objects, ensures that in enforcement, jacking device can not displacement.Suitable fixture is selected according to object, put into from jacking device one end by object, be placed on fixture 6, object end withstands on and heads into a little, move the pressure rod of hydraulic jack 1, jack hydraulic cylinder working, promotes to win 3 in succession forward, frame 2 and win in succession 3 acting in conjunction under, backup rolls 4 can advance along rack rail, fixture 6 simultaneously on backup rolls 4 also can clamp object, and drives object to move forward, thus makes object insert precalculated position.When backup rolls 4 operates to track front end, under the effect of top pressure spring 5, fixture 6 will decontrol object, and by jack pressure release, hydraulic cylinder shrinks, drive win in succession 3 and backup rolls 4 get back to and just establish state.Circulate this operation, can complete object and lay.
The present invention makes simply, with low cost, operates easy to carry, can when not destroying road surface, not using big machinery by the present invention, completes ground connection band iron of passing by one's way, the laying of poling, and with low cost, operates simple and easy.
Claims (3)
