the utility model belongs to the technical field of the architectural survey, concretely relates to a portable laser target instrument of assembling for measuring entrance to a cave central line deviation, the deviation measurement work of the large-scale entrance to a cave central line of mainly used industrial building.

Background art:

there are two conventional methods of measuring centerline deviation (for a square opening): one is that the plumb line is adopted to vertically measure to the ground downwards on the central lines of four sides of the opening layer by layer, four points are respectively formed, and the intersection point formed by the bullet lines of the diagonal points is the central point. Finally, comparing the data with the central point measured on the drawing to form deviation data. However, this method has numerous disadvantages: (1) the staff needs to move four times for each layer, which consumes a lot of time and is slow in measurement. (2) When the height of the floor is larger, the plumb line is obviously influenced by the action of wind force, and the measurement difficulty and accuracy can be undoubtedly increased. The other method is that point location is determined on the ground according to the center point of the drawing, then the vertical collimator is adopted for adjustment and calibration, after the reference point is aligned, a laser line is projected upwards, and a steel tape or a laser target with a side rod is adopted for measurement. This method also has disadvantages: the laser line cannot be found due to the opacity of the steel tape, and therefore, the measurement cannot be performed. And the laser target of a side band pole, the centre of a target can aim at the laser line from bottom to top, but because the side band pole is fixed difficultly and still need adopt the steel tape measure to measure after marking the position of the side line of the opening on the pole temporarily, the measuring error increases. Based on this, the utility model provides a portable laser target instrument of assembling for measuring entrance to a cave central line deviation is in order to solve above-mentioned problem.

the utility model aims at prior art not enough, provide a portable laser target instrument of assembling for measuring entrance to a cave central line deviation, improve on the basis that originally adopts the laser target perfectly, increased the quantity of member to mark the scale on the member, when forming stable the fixing, can carry out disposable measurement, disposable reading has reduced measured data greatly and has received the influence of objective factor, guarantees measured data's accuracy, has improved measuring efficiency.

The utility model adopts the following technical scheme:

the utility model provides a portable laser target assembling tool for measuring the deviation of the central line of a hole, which comprises a laser target bracket, a laser target and a rod piece; the laser target bracket is of a square frame structure with a hollow interior, and the laser target is arranged in the laser target bracket; the rod piece comprises four groups of supporting rods with the same structure, and the four groups of supporting rods are respectively arranged on four edges of the laser target bracket; the support rod is provided with scale marks.

Furthermore, the four groups of support rods are respectively and detachably arranged at the centers of the four sides of the laser target bracket.

Furthermore, the four sides of the laser target bracket are respectively welded with a screw rod, correspondingly, the end part of the supporting rod is provided with a screw cap matched with the screw rod, and the supporting rod is connected with the laser target bracket by screwing and fixing the screw rod and the screw cap.

Furthermore, the bracing piece includes that a plurality of groups connect gradually's branch, and adjacent branch can be dismantled and connect.

Furthermore, the one end of branch is provided with the nut, and the other end is provided with the screw rod, realizes dismantling the connection through nut and screw rod between the adjacent branch.

Furthermore, the support rod is a 304 stainless steel round steel pipe with the outer diameter of 20mm, and the length of the support rod is 100mm.

Furthermore, the four groups of support rods are perpendicular to the four sides of the laser target bracket respectively.

Furthermore, the laser target is detachably arranged on the laser target bracket.

The utility model has the advantages that:

(1) The utility model discloses set up the laser target bracket, install the laser target in the laser target bracket, and set up the bracing piece that has the scale mark on four limits of laser target bracket, compare in traditional laser target measuring device, this device structure is more stable, can once only measure, and once only reading has reduced the measured data greatly and has received the influence of objective factor, has guaranteed the accuracy of measured data, has improved measurement efficiency;

(2) The utility model comprises a plurality of groups of supporting rods which are connected in sequence, the number of the supporting rods can be adjusted according to the needs to adjust the length of the supporting rods, which can adapt to the measurement of the deviation of the central lines of the holes with different sizes and has wide application range;

(3) The utility model discloses wholly can dismantle, easily assemble, portable, transportation and accomodate to be convenient for the change of maintenance and partial component, the practicality is strong.
