Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a deep hole shell laser tracking measuring device. Background Art

[0002] With the continuous planning of urban underground tunnels, shield machines have been widely used in underground tunnel excavation projects. In the development process of shield machines, the main drive gearbox of the shield machine is the core component of the shield machine. In the production process, the workpiece has high requirements for the form and position tolerances such as the diameter, coaxiality, and position of each gear hole. Therefore, it is necessary to rely on precise distance measuring instruments for measurement to ensure that the workpiece size is qualified. At present, laser trackers are often used for measurement. Laser trackers are instruments that use lasers as distance measurement means and are equipped with reflective targets. They have small laser divergence and high measurement accuracy, so they have been widely used in the field of distance measurement.

[0003] However, in the actual measurement process, since the gear holes in the main drive gearbox of the shield machine are all in deep holes with a diameter greater than 200 mm and are nested layer by layer, it is difficult to manually place the target ball of the laser tracker to fully cover the main drive gearbox. The target ball cannot be fixed and placed at a deeper measurement position, resulting in low measurement accuracy and inaccurate measurement results. Especially when measuring the size of deep hole shell workpieces, the measurement accuracy error is more prominent.

[0004] Although Chinese utility model patent CN219082714U discloses a laser tracker mobile measurement frame, including a base, a fixed cylinder and a support rod, the fixed cylinder is fixed on the top of the base, the support rod is slidably penetrated on the inner top wall of the fixed cylinder, and a screw rod 1 is rotatably provided on the inner bottom wall of the fixed cylinder. The laser tracker mobile measurement frame of this scheme can adjust the moving wheel in and out of the groove by rotating the rotating handle to drive the screw rod 2 to rotate and move, so as to facilitate the movement and support of the moving seat; when adjusting the height of the laser tracker, the toggle rod is rotated to drive the adjustment ring to rotate, thereby driving the gear ring to rotate, thereby driving the gear 2 to rotate, thereby driving the gear 1 to rotate, thereby driving the screw rod 1 to rotate, thereby driving the support rod to move, thereby adjusting the height of the laser tracker. However, this mobile measurement frame can only realize the movement, storage and height adjustment of the laser tracker, and the adjustment method is complicated and the adjustment angle is single. It is also impossible to accurately fix and place the target ball at the measurement position of the deep hole shell workpiece, resulting in a large measurement accuracy error of the deep hole shell workpiece.

[0016] Furthermore, the moving member includes a connecting seat, a moving wheel rotatably connected to the connecting seat, and a brake pad arranged on the connecting seat and used for elastically abutting against the moving wheel.
