Description

Technical Field

[0001] The utility model relates to the technical field of shaft construction, in particular to a dual-purpose connection measurement bracket. Background Art

[0002] Linking measurement is the measurement work that transfers the plane coordinate system and elevation system of the ground to the underground so that the ground and underground can use the same coordinate datum and elevation datum. Linking measurement is generally used in the penetration of mine shafts. In underground projects, in order to establish a unified coordinate system and elevation datum between the ground and the underground, the ground coordinate system and elevation datum should be transferred to the underground through tunnels, inclined shafts and vertical shafts. The transfer of this underground starting data is called linking measurement.

[0003] Contact measurement requires a bracket that can suspend a steel wire or steel ruler, hang a 10kg weight at one end of the bottom of the steel wire or steel ruler, and place the weight in damping fluid, and use a total station or level to achieve contact measurement. However, the existing measurement bracket often uses a steel pipe, and fixes the steel wire or steel ruler on a steel pipe by winding it, and then the steel pipe is placed horizontally and fixed on the guardrail or protective wall on both sides of the shaft opening. This method makes the steel pipe fixed in position and cannot adjust the angle. This method requires fixing the steel pipe first, and then selecting the burial position near the well point and underground point according to the position of the steel pipe. The point selection process also needs to cooperate with the total station to find the angle, which greatly wastes manpower and time.

[0004] Chinese patent CN202320796465.7 discloses "A movable contact measurement bracket", publication number CN220356369U, the device includes a support rod area and a probe area, the support rod area includes two tail support rods and two inner support rods in a square shape, the length ratio of the inner support rod to the tail support rod is 1:2~2.1, the tail support rod and the inner support rod are arranged in parallel, and a square bracket seat is vertically arranged between the tail support rod and the inner support rod; the probe area includes two probe brackets and probes, the probe area is 1~5° elevation angle, and is in an ascending type; the probe bracket continues to extend more than 0.80m after being connected from the tail support rod to the inner support rod, and the probe is connected to the end of the probe bracket away from the side of the support rod area. However, the device has some defects: the support rod area of ​​the device is a frame connected by connecting rods, lacks a base connected to the ground, and is prone to tipping under the action of external force.
