[0001] This utility model relates to the field of anchor cable support technology, and in particular to an anchor cable support operation platform for the bottom corner of coal mine roadways. Background Technology
[0002] To control the convergence deformation of the bottom corner of the roadway sidewall and ensure the effective use of the roadway cross section, it is usually necessary to implement anchor cable support for the bottom corner of the roadway. An anchor cable machine is a type of anchor cable support equipment that can move along the drilling direction. The construction of anchor cables for the bottom corner of the roadway sidewall is mostly carried out by ropes and people carrying them. The anchor cable machine is hoisted and connected to the drilling position to drill holes, and then anchor cables or anchor rods are installed for support.
[0003] Most existing anchor cable support devices for coal mine roadway corners are equipped with rope hoisting structures. During use, the anchor cable machine is raised and lowered using rope hoisting, and the ground or other open planes support the machine. However, the stability of the anchor cable machine is often poor during hoisting, which can easily lead to collisions and injure workers and equipment. In addition, the time required for the swaying anchor cable machine to connect with the anchor cable drilling position is long, affecting work efficiency. As a result, the efficiency and safety of the anchor cable support devices for coal mine roadway corners are reduced.
[0004] Therefore, in view of the problems that existing coal mine roadway bottom corner anchor cable support devices often have poor stability and are prone to collisions during use, and that the shaking anchor cable machine takes a long time to reach the anchor cable drilling position, resulting in a decrease in the efficiency and safety of the coal mine roadway bottom corner anchor cable support device, a coal mine roadway bottom corner anchor cable support operation platform with a stable moving structure can be designed.
