Description

[0001] The present application relates to the field of tunnel construction equipment, in particular to a vertical arch mechanical arm and a trolley. BACKGROUND

[0002] In the process of tunnel construction, it is necessary to open blasting holes or anchor rod installation holes in the tunnel. The commonly used engineering machinery for drilling is a rock drilling trolley. For the installation of arch supports, an arch support installation trolley can be used.

[0003] In related technologies, the vertical arch mechanical arm of the trolley mainly includes a telescopic arm and a hanging basket installed on the telescopic arm. The front end of the telescopic arm is provided with a gripper for vertical arching. Workers are located in the hanging basket, which is convenient for checking the vertical arching position, operating the mechanical arm, welding the mesh, and installing the connecting bolts between the arch segments. Since the existing vertical arch mechanical arm is used on a conventional arch support installation trolley (for example, the arch support installation trolley shown in the Chinese patent No. 201811386069.7), the existing arch support installation trolley generally performs construction in a wide space in front of the working face. Therefore, the existing vertical arch mechanical arm does not have to worry about the space activity restriction of the arm support. However, if the existing vertical arch mechanical arm is used for an integrated machine set, because other vehicles need to pass under the trolley of the integrated machine set, the volume of the integrated machine set is relatively large, and the outer side is relatively close to the tunnel wall, leaving limited space for the vertical arch mechanical arm to move. Therefore, the existing vertical arch mechanical arm cannot meet the demand for the flexible operation of the mechanical arm in a narrow space. Therefore, there is an urgent need for a vertical arch mechanical arm structure that can be used for an integrated machine set. SUMMARY
