Description

Technical Field

[0001] The invention relates to the technical field of coal mine tunnel excavation support equipment, in particular to a six-arm top bolt bolter. Background Art

[0002] With the national policy of building green mines and smart mines in the coal mining field in recent years, coal mining production has reached a new level in terms of safety, efficiency, greenness, intelligence, etc., and various main engine manufacturers are also vigorously responding to national policies, making every effort to ensure the safety and efficiency of tunnel excavation, and constantly upgrading their products. However, the imbalance between mining and excavation is still the most prominent, and the main reason is the imbalance between excavation and support.

[0003] At present, the methods to solve the imbalance of excavation and support are divided into two categories: one is the synchronous operation of excavation and support; the other is to excavate first and then support. Among them, the excavation and anchoring machine (such as Sandvik's MB670, etc.) used in the synchronous operation of excavation and support is currently a very good way to solve this problem. The equipment forms a lane in one time, supports the top anchor and the side anchor in parallel, the working process is continuous, the empty top time is short, the excavation efficiency is high, and it is safe and efficient. However, due to structural limitations, this equipment requires a large empty top distance in the lane, at least between 1.5 and 2m, and has a large disturbance to the surrounding rock of the lane. Since most of the geological conditions in my country are poor and the surrounding rock is unstable, it is easy to have various adverse working conditions such as roof collapse, side wall spalling, bulging top, bulging bottom, faults, etc., so this type of equipment cannot exert its powerful excavation capacity in 90% of the mines in China, and the cost is more than 10 million yuan, which is very expensive. It is not the current mainstream excavation and anchoring equipment and cannot solve the problem of mining and excavation imbalance in about 90% of China's coal mines.

[0004] There are many methods of tunneling with excavation first and support later, such as: (1) The most common method is to use a tunneling machine and a mining pneumatic anchor drill in combination. The general working steps are as follows: the tunneling machine first excavates and then leaves the bottom coal before retreating. The worker stands on the coal pile and holds the pneumatic anchor drill to carry out anchor and cable support. This method has good mobility and simple operation, but the labor intensity of the workers is high and the safety is poor. (2) The tunneling machine and the mining two-arm anchor drill vehicle are used in combination. The general working steps are as follows: the tunneling machine first excavates without leaving the bottom coal and then retreats to pass the anchor drill vehicle. The anchor drill vehicle enters the working face and supports the entire section or part of the section. This method greatly reduces the labor intensity of the workers and is slightly safer than a handheld pneumatic drill. However, due to the limited space of the entire machine, the operating station platform is relatively small, the movement space is limited, the ergonomic matching is not satisfactory, the equipment movement is relatively complex and the hole is difficult to align, and the anchor support efficiency is lower than that of a handheld pneumatic anchor. (3) The continuous mining machine and the mining anchor drill vehicle are used in combination. Two or three tunnels are excavated simultaneously, and joint tunnels are opened between the tunnels. The continuous mining machine excavates tunnel 1, and the anchor drilling vehicle supports tunnel 2. The equipment works in a staggered manner. This method has a long effective working time of the equipment, a high equipment utilization rate, and high excavation efficiency. Since the geological conditions of most coal mines in China are relatively poor, this excavation work method has a long staggered time, resulting in a long empty roof reservation time, which is prone to accidents such as roof collapse and rock collapse. The country prohibits the use of this excavation method. (4) The rear-mounted anchor mining machine is used in conjunction with various anchor rod and cable equipment. The general working steps are as follows: first dig one row, without retreating the machine, the cutting part is centered, the cutting head is grounded, and then the anchor drills on the two platforms slide to the front. The two anchor drills theoretically support the entire section, but the actual efficiency is low, and the supporting equipment needs to be used in conjunction with each other. In addition, due to the limited space of the entire machine, the operating station platform is relatively small, the movement space is limited, the ergonomic matching is not satisfactory, the equipment movement is relatively complex and the hole is difficult to align, and the anchor support efficiency is lower than that of handheld pneumatic anchors. (5) The anchor drill and anchor transfer unit are used in conjunction with each other. The general working steps are as follows: the anchor drill first digs one or two rows without retracting the machine, with the cutting part centered and the cutting head grounded. The operator then stands on the platform and uses its own hydraulic anchor drill to carry out top anchor support and partial auxiliary anchor support. The anchor transfer unit that follows immediately drives the remaining anchors and cables. This anchor drill is more advanced than the above equipment that digs first and then supports. It is safer for personnel and more efficient in digging. The disadvantage is that the workload for later maintenance is also large. At present, domestic and foreign products are relatively immature and are all under research and improvement.

[0005] This application is based on the above-mentioned unbalanced situation of excavation and support, and innovates a six-arm top anchor bolter and boring machine, which enables workers to stand on a large platform with a full section and operate six top anchor drilling rigs for synchronous support, thereby improving the efficiency of top anchor support and shortening the excavation empty top time, thereby solving the difficult problems of high labor intensity of workers, low efficiency of top anchor support and poor personnel safety. It is the first top anchor bolter and boring machine in the country with strong integration and reasonable design. Summary of the invention
