Abstract

The utility model provides a secondary alignment device for tubular pillar lifting, which comprises a clamping device and a jacking device mounted on the clamping device, wherein the clamping device comprises a clamping ring; in the clamping ring, multiple sections of structures are connected end to end to form a ring shape, a protuberance is arranged on the inner side of each section, and wear-resistant rubber is mounted on the protuberance; the jacking device is mounted on the outer side of each section of clamping ring respectively; the jacking device comprises a jacking support and a jack; one end of the jacking support is connected with the outer side of the clamping ring and is of a detachable structure, and the other end is close to a jacking end at the upper part of the jack. The device provided by the utility model can solve the technical problems that the vertical deviation is excessive and the height needs to be adjusted in a tubular pillar lifting process, and can realize secondary alignment of field installation of a tubular pillar.

Description

Tubular pillar lifting secondary alignment device
Technical field
The utility model relates to tubing string technical field of construction, refers more particularly to a kind of tubular pillar lifting secondary alignment device.
Background technology
In tubular pillar lifting, put in place by often running into following situation: 1, pillar perpendicularity deviation is excessive, need to adjust; 2, pillar absolute altitude mal, needs absolute altitude at the bottom of adjustment column.While conventionally running into above-mentioned two situations, be all to utilize crane adjustment, pillar is sling to adjust absolute altitude and squareness, but this scheme time is longer, efficiency is low, and has increased crane machine-team expense, needs lifting also to increase potential safety hazard.Therefore be necessary to take a kind of new aligning method to reduce hoisting cost, raise the efficiency, and guarantee the safety of centering.
Summary of the invention
Technical problem to be solved in the utility model is the technical deficiency over against above-mentioned existence, provide in a kind of solution tubular pillar hoisting process vertical missing excessive, with the technical matters that highly needs to adjust, can realize the on-the-spot tubular pillar lifting secondary alignment device that secondary centering is installed of tubular pillar.
The utility model solves the technical scheme that its technical matters adopts:
Tubular pillar lifting secondary alignment device, it is characterized in that: include fixing device and be arranged on the jacking apparatus on fixing device, wherein said fixing device includes clamping ring, clamping ring is that multi-segment structure first place connects into annular, and be provided with projection each section of inner side, antifriction rubber is installed in projection, described jacking apparatus is arranged on respectively the outside of each section of clamping ring, jacking apparatus includes jacking support and jack, described jacking is supported one end and is connected to clamping ring outside, and be demountable structure, the other end is pressed close to the jacking end on jack top.
In such scheme, described clamping ring is equally divided into four sections, and the jacking apparatus in each section of outside becomes 90 degree angle settings.
In such scheme, segmentation place of described clamping ring is provided with fastening node, and fastening node includes connecting portion and overbolt, by overbolt, two sections of adjacent clamping rings is linked together, and can adjust elasticity by overbolt.
In such scheme, the junction in described jacking support and clamping ring outside adopts draw-in groove to be connected, in every section of clamping ring outside, be welded with the fixed pedestal with inverted L shape groove, the end that jacking is supported is welded into the inverted L shape structure matching with it, and can inject interior the fixing with for convenience detach of groove of fixed pedestal.
The principle of the utility model device is: clamping ring is divided into four sections, section with section between with fastening node, be connected, can regulate the tightness of clamping ring to shaft.By stepping up to encircle the clamping of coupled columns, make abrasion-proof rubber cushion and shaft produce huge friction force, recycling hydraulic jack arrives the effect of lifting shaft by movable brace rod.
The concrete use step of the utility model device is:
1, top cable wind rope is kept a grip in La Hao garden;
2, in shaft bottom, clamping ring is installed in suitable position, by regulating the overbolt in fastening node, reaches the elasticity needing.
3, movable brace rod is installed, movable brace rod is snapped in the draw-in groove of fixed pedestal.
4, lay hydraulic jack, start hydraulic jack.According to the angle of inclination of shaft, the hydraulic jack on the four direction of adjusting, until reach vertical.At the bottom of adjustable column, during absolute altitude, open four hydraulic jacks simultaneously, regulate as required jack stroke.
Main beneficial effect of the present utility model is:
1, device is simple, easy to operate, has avoided the use of crane, has solved in tubular pillar hoisting process vertical missing excessive, and highly needs the technical matters of adjustment, has improved centering efficiency, has saved crane machine-team expense.
2,, without lifting, improved safety.
