Description
Technical field
The utility model prestressed stretch-draw field, especially a kind of multifunctional all pre-stress stretching device.
Background technology
In order to expand the scope of application of annular concrete electric pole, over the years, many places use the electric pole that tip footpath is larger, moment is higher, tapering is larger.This kind of electric pole mostly is partially prestressed concrete electric pole, replaces part steel pipe tower and steel tower to use as a kind of Novel rod tower structure without bracing wire.This rod-type has good cost performance, uses the demand meeting " amphitypy three is new ", create good economic benefit and social benefit to electric pole manufacturing enterprise in electrical network.
Generally adopt fixed stretch-draw to the tensioning equipment that annular concrete electric pole carries out, although stretch-draw effect is better, work efficiency is also good, and which is heavier, and automaticity is also not high.If be engaged in tensioning equipment place, build an easy boom hoisting, then more can save labour intensity.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of multifunctional all pre-stress stretching device, has good mobility, by supporting the electric bar mould of different size the improvement of top foot.
The technical solution adopted in the utility model is as follows: a kind of multifunctional all pre-stress stretching device, comprise electric block, stretch-draw main part and servo oil pump hydraulic system, described electric block is connected with stretch-draw main part, described stretch-draw main part is positioned at below electric block, and described servo oil pump hydraulic system is connected by high-pressure oil pipe with stretch-draw main part; Described servo oil pump hydraulic system comprises high pressure pumping station, pressure meter, oil pressure sensor and servomotor, the oil pump stop valve in described Serve Motor Control high pressure pumping station; Described stretch-draw main part comprises top foot, top board, stretch-draw pawl and stretch-draw jack, described top board is sleeved on stretch-draw jack, the through hole supplying the pulling shaft of stretch-draw jack to pass through is provided with in the middle part of described top board, the pulling shaft of described stretch-draw jack through top board through hole and extend out to the other end of top board, described stretch-draw pawl is dismountable to be connected on the pulling shaft of stretch-draw jack, described top board props up electric pole by the top foot that top board is arranged, add sliding sleeve in the junction of top board and top foot, described top foot realizes moving horizontally to adapt to electric pole specification by sliding sleeve.
Under normal circumstances in order to realize stretch-draw object, by realizing stretch-draw with the top foot changing different size, but after top board and the junction of top foot install sliding sleeve additional, top to move horizontally in realization, can directly adjust the sufficient specification in top completely to meet stretch-draw demand.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: by installing boom hoisting and sliding sleeve additional, improve automaticity, reducing labour intensity, have saved labour and financial resources.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
A kind of multifunctional all pre-stress stretching device, comprise electric block 1, stretch-draw main part 2 and servo oil pump hydraulic system 3, described electric block 1 is connected with stretch-draw main part 2, described stretch-draw main part 2 is positioned at below electric block 1, and described servo oil pump hydraulic system 3 is connected by high-pressure oil pipe with stretch-draw main part 2, described servo oil pump hydraulic system 3 comprises high pressure pumping station, pressure meter, oil pressure sensor and servomotor, the oil pump stop valve in described Serve Motor Control high pressure pumping station, described stretch-draw main part 2 comprises top foot 4, top board 5, stretch-draw pawl 6 and stretch-draw jack 7, described top board 5 is sleeved on stretch-draw jack 7, the through hole supplying the pulling shaft 8 of stretch-draw jack 7 to pass through is provided with in the middle part of described top board 5, the pulling shaft 8 of described stretch-draw jack 7 through top board 5 through hole and extend out to the other end of top board 5, described stretch-draw pawl 6 is dismountable to be connected on the pulling shaft 8 of stretch-draw jack 7, described top board 5 props up electric pole by the top foot 4 that top board 5 is arranged, sliding sleeve 9 is added in the junction of top board 5 and top foot 4, described top foot 4 realizes moving horizontally to adapt to electric pole specification by sliding sleeve 9.
Under normal circumstances in order to realize stretch-draw object, by realizing stretch-draw with the top foot changing different size, but after top board and the junction of top foot install sliding sleeve additional, top to move horizontally in realization, can directly adjust the sufficient specification in top completely to meet stretch-draw demand.
Operating principle:
Hanging stretch-draw main part by electric block can be upper and lower, moves left and right, light flexibly.Top foot adds sliding sleeve, can carry out horizontal direction and move on top board.By movable top foot, stretch-draw requirement is met to the size of rod-type, by changing stretch-draw pawl, stretch-draw has been realized to major part stretch-draw and microcephaly's stretch-draw.
During stretch-draw, movable top foot aligns mould, and jack pulling shaft is connected with tension ground tackle, starts servo oil pump hydraulic system, gathers pressure data, by Serve Motor Control oil pump stop valve, guarantee the accurate of prestressing force pull-up values by oil pressure sensor.After tension ground tackle is fixing, namely oil pump oil return unloading completes stretching process.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
