Description
Technical field
The utility model belongs to blast funnace hot blast stove foundation construction technical field, is specifically related to a kind of circular foundation bolt location easy device.
Background technology
The basis of blast funnace hot blast stove comprises four groups of circular foundation bolts, and they are important installation components of stationary heat wind furnace.Because the diameter of foundation bolt is big, installation accuracy requires height, so in the unwrapping wire process of the location of foundation bolt, all can at first measure the center of circle of each foundation bolt of hot-blast stove with accurate location.
In order to locate the center of circle of each foundation bolt, operation in the past is: the circle centre position at every group of foundation bolt is made the transit fixed mount with the steel plate of the above thickness of 10mm, and do support with the angle steel of ∠ more than 50, after guaranteeing its stability, control angle between foundation bolt with to its accurate location with the transit corner.Yet this mode can be wasted lot of materials and process time, and installation accuracy is also often undesirable.For example: according to aforesaid operations, the transit fixed mount of every group of foundation bolt needs one of the steel plate of the above thickness of 10mm, and size is about 1m * 1m, needs four in ∠ 50 angle steel, length will surpass the height of foundation bolt, needs eight in long ∠ 50 angle steel of 1m as bearing diagonal in addition.So with the about 78.5kg of steel plate, the long meter of every 3.5m of four ∠ 50 angle steel, every group of angle steel weighs 3.77 * (3.5 * 4+1 * 8) m=82.94kg altogether, four bases promptly need (78.5+82.94) * 4=645.76kg, and can't be after finish the location as his usefulness, aforementioned calculation does not also count manual manufacture expense etc.; In addition, this action need time more than one day, construction progress also there is considerable influence; In this operating process, transit is subjected to the influence of each side factors such as weather also relatively more remarkable when angular measurement, the accurate location that is not easy to realize whole foundation bolts.
The utility model content
Technical problem to be solved in the utility model just provides a kind of circular foundation bolt location easy device, can locate the foundation bolt of blast funnace hot blast stove economical, efficiently, reliably.
For solving the problems of the technologies described above, easy device is used in a kind of circular foundation bolt location that the utility model provides, and is used for the foundation bolt on the hot-blast stove basis is positioned, and it comprises a pair of vertical railing of measurement control and a pair of measurement control horizontal bar bar; The vertical railing of a pair of measurement control is arranged at horizontal two edges on described hot-blast stove basis respectively, and a pair of measurement control horizontal bar bar is arranged at vertical two edges on described hot-blast stove basis respectively; The edge laterally is provided with some parallel bolt transversal lines between the vertical railing of a pair of measurement control, the distance of adjacent bolt transversal line equals the longitudinal pitch of corresponding position two row's foundation bolts, longitudinally be provided with some parallel bolt longitudinal axis between a pair of measurement control horizontal bar bar, the distance of adjacent bolt longitudinal axis equals the horizontal spacing of corresponding position two row foundation bolts.
In the technique scheme, described bolt transversal line is five, and the bolt longitudinal axis is 20.
In the technique scheme, described a pair of vertical railing of measurement control and a pair of measurement control horizontal bar bar can be monolithic construction.
The beneficial effects of the utility model are: this apparatus structure is simple, and need not a large amount of raw material and make, and the vertical railing of the control of measurement wherein and measure control horizontal bar bar and face frontier defense and protect need not after the installation also to can be used as after dismounting, location are finished.Bolt longitudinal axis and the bolt transversal line pulled down are reusable, so the cost of whole device is very low; This Unit Installation is also comparatively easy, can finish the location of whole foundation bolts in one day; In addition, owing to use in the process of this device, transit only is used for the measurement of horizontal range, so be subjected to the influence of factors such as weather in the measuring process (wind, sunlight), support shakiness, measure error less, can reach the requirement of error in ± 2mm fully.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Among the figure: 1-hot-blast stove basis, 2-foundation bolt, 3-hot-blast stove longitudinal centre line, 4-hot-blast stove cross central line, 5-measure the vertical railing of control, horizontal bar bar, 7-bolt longitudinal axis, 8-bolt transversal line are controlled in 6-measurement.
The specific embodiment
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, easy device is used in this circular foundation bolt location, comprises a pair of vertical railing 5 of measurement control and a pair of measurement control horizontal bar bar 6.The vertical railing 5 of a pair of measurement control is arranged at horizontal two edges on hot-blast stove basis 1 respectively, and a pair of measurement control horizontal bar bar 6 is arranged at vertical two edges on hot-blast stove basis 1 respectively, and the two can be the monolithic construction that is formed by angle steel or scaffold building.Along laterally being provided with five parallel bolt transversal lines 8, the distance of adjacent bolt transversal line 8 equals the longitudinal pitch of corresponding position two row's foundation bolts 2 between the vertical railing 5 of a pair of measurement control.Longitudinally be provided with 20 parallel bolt longitudinal axis 7 between a pair of measurement control horizontal bar bar 6, the distance of adjacent bolt longitudinal axis 7 equals the horizontal spacing of corresponding position two row foundation bolts 2.
The operating principle of this device is: at first, set up the vertical railing 5 of measurement control with Φ 48 steel pipe scaffolds and control horizontal bar bar 6 with measuring around hot-blast stove basic 1; Then, according to the prior spacing data in length and breadth of using 2 of the good foundation bolts of CAD Lofting Calculation, locate on the ground beyond the hot-blast stove basis 1 with transit, five bolt transversal lines 8 and 20 bolt longitudinal axis 7 are separately positioned on a pair of vertical railing 5 of measurement control and a pair of measurement control horizontal bar bar 6, bolt transversal line 8 and bolt longitudinal axis 7 can be selected solid nylon wire etc. for use, and then the intersection point of five bolt transversal lines 8 and 20 bolt longitudinal axis 7 has comprised the home position of all foundation bolts 2; At last, reinforcing each foundation bolt 2 according to aforementioned positioning result gets final product.
After the construction end, vertical railing 5 of measurement control and measurement are controlled horizontal bar bar 6 and can not dismantled, and the frontier defense of facing that is used for hot-blast stove is protected; One of the centre of five bolt transversal lines 8 is a hot-blast stove cross central line 3, comprise four hot-blast stove longitudinal centre lines 4 in 20 bolt longitudinal axis 7, after finishing, this hot-blast stove cross central line 3 and four hot-blast stove longitudinal centre line 4 constructions can not remove yet, the location that is used for the hot-blast stove installation process, other bolt transversal line 8 and bolt longitudinal axis 7 are promptly dismountable after finish the location.
