Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine roadway excavation surrounding rock control technology, and in particular to a tracked self-moving temporary support roller pressure shifting device. Background Technology
[0002] Coal mine roadway excavation, as the foundation and cornerstone of coal mine development, is a core component of the coal mining process. It not only concerns mine safety and production efficiency but is also crucial for the sustainable operation of mine production. Within the entire coal mining system, the quality of roadway excavation technology directly impacts the mine's resource development potential and economic benefits, making its importance undeniable. However, due to complex geological conditions, uneven resource distribution, and the limitations of modern mining technology, achieving optimal mining balance is often difficult, especially when roadway excavation speeds are slow. This problem becomes more pronounced, increasing costs and potentially leading to safety hazards.
[0003] In modern mining operations, the application of temporary support frames has become a key factor in ensuring the safety and improving efficiency of tunneling operations. These frames, constructed from high-strength metal structures, not only bear enormous weight but also bear the responsibility of supporting and protecting the rock strata above the work area. This design effectively prevents collapses caused by rock movement or roof pressure, thus providing miners with a stable and safe working environment. Using this temporary support equipment, miners can focus on their work without worry, without fear of sudden rock collapses or other potentially life-threatening accidents. Furthermore, the introduction of temporary support frames facilitates the separation of tunneling and support, which not only improves operational efficiency but also enhances workers' sense of security.
[0004] However, in recent years, the temporary support systems on roadheaders have suffered from problems such as small roof support area and low support strength, often failing to meet the requirements for supporting newly excavated exposed roofs. To address this, frame-type temporary support devices, especially tracked self-propelled temporary support devices, have been introduced. These devices employ high-strength metal frame structures, providing large roof support area and high support capacity, thus offering a stable and safe working environment for construction workers. However, existing tracked self-propelled temporary support devices also suffer from the problem of short-term roof gaps caused by the need to lower the support frame before moving it, posing a potential safety hazard and potentially leading to serious accidents such as roof subsidence and leakage. Therefore, improving the reliability and safety of roof support technology and enabling pressurized relocation of tracked self-propelled temporary support devices is crucial for ensuring the safety of on-site construction personnel.

The spring 7 provides an elastic force to drive the strut 6 to swing upward, so that the support roller 5 can contact the roof of the roadway.
[0028] During the forward movement of the tracked self-moving support 1, the spring 7 diagonally pulls the support rod 6, keeping the support roller 5 in close contact with the roadway roof.

Multiple crossbeams 8 are sequentially and spaced apart on the upper part of the longitudinal beams 9 along the longitudinal direction. Support rollers 5 are disposed between adjacent crossbeams 8. The longitudinal beams 9 are arranged at equal intervals, and the crossbeams 8 are arranged at equal intervals, with a spacing of 1600mm between the crossbeams 8.
[0030] In this embodiment, both the crossbeam 8 and the longitudinal beam 9 are square beams. The diameter of the supporting roller 5 is no greater than the height of the crossbeam 8 itself, ensuring that the support base 2 can support the roadway roof during support. In this embodiment, the diameter of the supporting roller 5 is 80mm, and the height of the crossbeam 8 is 100mm.
