Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lift-on/lift-off type steel column welded top positioner, it is a kind of auxiliary locator, artificial righting can be replaced, keep welding position and the perpendicularity of steel column when steel column welded top, avoid workmen and exert oneself for a long time or keep same state and produce fatigue.Only need a workmen during operation, and workmen can, away from welding procedure place, stop by burn and scald or the generation injuring accident by a crashing object completely, security performance improved, dangerous performance reduces.Meanwhile, decrease human and material resources, improve efficiency greatly, reduce cost of labor.
For achieving the above object, the utility model realizes by the following technical solutions:
A kind of lift-on/lift-off type steel column welded top positioner, comprise lever balance device, base support means, described lever balance device and base support means are articulated and connected.
Described lever balance device comprises stopper slot box, hand-held lever, steel plate with holes, and at the parallel welding in fulcrum place two steel plates with holes of hand-held lever, two steel plates with holes form hinged groove, are welded and fixed stopper slot box in one end of hand-held lever.
Described base support means comprises upper bed-plate, stop sleeve, lower bottom base, and upper bed-plate is plugged on the top of stop sleeve, and lower bottom base is plugged on the bottom of stop sleeve.
Described upper bed-plate comprises upper mounted plate, steel plate with holes, upper bush, and Interal fixation with holes is on upper mounted plate, and upper mounted plate is fixed on one end of upper bush.
Described lower bottom base comprises bottom plate, lower sleeve, and bottom plate is fixed on one end of lower sleeve.
Compared with prior art, the beneficial effects of the utility model are:
A kind of lift-on/lift-off type steel column welded top positioner, it is a kind of auxiliary locator, artificial righting can be replaced, keep welding position and the perpendicularity of steel column when steel column welded top, avoid workmen and exert oneself for a long time or keep same state and produce fatigue.Only need a workmen during operation, and workmen can, away from welding procedure place, stop by burn and scald or the generation injuring accident by a crashing object completely, security performance improved, dangerous performance reduces.Meanwhile, decrease human and material resources, improve efficiency greatly, reduce cost of labor.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in detail, but it should be noted that enforcement of the present utility model is not limited to following embodiment.
As Figure 1-3, a kind of lift-on/lift-off type steel column welded top positioner, comprise lever balance device, base support means, described lever balance device and base support means are articulated and connected.
Lever balance device comprises stopper slot box 1, hand-held lever 2, steel plate with holes 3, forms hinged groove, be welded and fixed stopper slot box 1 in one end of hand-held lever 2 at the parallel welding in fulcrum place two steel plate with holes 3, two steel plates 3 with holes of hand-held lever 2.
Because steel pipe is circular end face, its anti-shearing force is better than shaped steel material, and twisting resistance is better than shaped steel, and therefore hand-held lever 2 adopts steel pipe manufacturing.
Stopper slot box 1 is the can without upper cover made with Plate Welding, and stopper slot box 1 should weld reinforcement with the junction of hand-held lever 2.
A point selection of hand-held lever 2 is in the appropriate location near stopper slot box 1.
At the extension bar of the handheld terminal installing insulating wood materials of hand-held lever 2, the weight of lever can be alleviated, but tie point is solid and reliable.
Base support means comprises upper bed-plate, stop sleeve 8, lower bottom base, and upper bed-plate is plugged on the top of stop sleeve 8, and lower bottom base is plugged on the bottom of stop sleeve 8.
The stop sleeve 8 of different lengths specification can be equipped with, according to the stop sleeve 8 of the setting height(from bottom) choice for use proper height of different construction location or different steel column.
Upper bed-plate comprises upper mounted plate 9, steel plate with holes 3, upper bush 5, and steel plate 3 with holes is fixed on upper mounted plate 9, and upper mounted plate 9 is fixed on one end of upper bush 5.
Lower bottom base comprises bottom plate 7, lower sleeve 6, and bottom plate 7 is fixed on one end of lower sleeve 6.
The design of bottom plate 7 mainly in order to prevent stop sleeve 8 directly and earth surface time sink.
Upper bush 5, lower sleeve 6, stop sleeve 8 can select circular sleeve or polygon sleeve, but the sleeve of the necessary same shape of choice for use of same set of device.
During use: first by complete for the assembling of a kind of all parts of lift-on/lift-off type steel column welded top positioner, bottom plate 7 is placed on ground, select the stop sleeve 8 of proper height to be socketed on lower sleeve 6, then upper bush 5 grafting is entered in stop sleeve 8.Now steel plate 3 with holes is placed in the upper end of base support means, by bearing pin by hinged with the hinged groove on lever balance device for the steel plate with holes 3 in base support means.
During weldable steel column, the welding position of centering steel column needs two people, after the welding position centering of steel column, the bottom of steel column is placed in the stopper slot box 1 of lever balance device, one people pushes down lever at the other end of lever, steel column is fixed, now just can implement welding, after welding, lift-on/lift-off type steel column welded top positioner be removed.
The utility model is specially adapted to the top lifting welding procedure of the steel column that volume is large, quantity is many.Therefore the utility model not only can be used in cable testing bridge joist steel upright welding engineering, also may be used for the installing engineering of installing above other similar support welding equipment.
