Technical Field

Background

The traditional steel wire casting method needs to erect a support installation steel wire at the casting position when in use, and a pendant drop ball is hung at the bottom of the steel wire and is immersed into a barrel with damping liquid for stabilization. And transmitting the plane coordinate of the top of the steel wire to the bottom of the steel wire by using a plumb principle to perform pointing.

When the traditional steel wire casting method is used for casting operation, a series of preparation operations such as erecting a steel wire hanger, installing a vertical ball, installing a damping barrel, additionally installing a positioning target and the like are required, so that the method is very complicated, and wastes time and labor.

On the other hand, the influence of weather is large, and steel wire throwing cannot be carried out in windy weather.

In addition, the influence of the environment is large, the underground observation light is dim in connection with measurement, and the steel wire with low visibility is difficult to aim; if other construction is performed around the robot, the generated vibration increases the aiming difficulty.

More importantly, the steel wire needs to wait for the steel wire to be stable and static when the traditional steel wire is put into a point for operation, and the invalid waiting time is too long.

Generally speaking, the process preparation of the traditional contact measurement technology is complex, and the steel wire hanging bracket, the installation of the vertical ball, the installation of the damping barrel and the installation of the positioning target consume time and labor. Although the damping barrel is arranged to reduce disturbance, the waiting time for the steel wire to be vertical is long, and the accuracy and the timeliness of the measurement work cannot be guaranteed due to the influence of weather and other environmental factors.

In view of this, the present application is specifically made.
