[0002] "Geological exploration" refers to the investigation and research activities of exploring and detecting geology through various means and methods to determine the appropriate bearing layer, determine the foundation type according to the bearing capacity of the foundation of the bearing layer, and calculate the foundation parameters. It is to find out the industrially significant mineral deposits in the mineral survey, to provide the mineral reserves and geological data required for mine construction design in order to find out the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to investigate and study the geological conditions such as rocks, strata, structures, minerals, hydrology, and landforms in a certain area. In the process of horizontal tunnel excavation, it is often necessary to set up temporary support at the lower end of the top rock plate. Temporary support refers to a temporary support method that takes measures to support the top plate to prevent the rock from falling during underground operations so that construction can continue. However, the existing temporary support is often... It is set on the tunneling vehicle, which moves synchronously with the tunneling vehicle and deploys the temporary support through hydraulic rods to achieve support for the top rock slab. However, since the temporary support is set on the tunneling vehicle, the tunneling vehicle is often large in size, moves slowly and has low efficiency, the layout of the entire temporary support takes a lot of time, which in turn affects the ease of use and timeliness of the entire temporary support device. At the same time, the temporary support structure is fixed, and has poor applicability to cave types with different cross-sectional shapes. It is often necessary to prefabricate relevant support equipment based on the known cave structure parameters, which is inefficient and economical.

[0015] A method for using a temporary support device for geological exploration horizontal tunnel excavation, comprising the following steps:

[0016] S1. First, the user drives the matching wheel to rotate through the driving motor, so as to drive the connecting crawler to rotate through the matching wheel and the meshing block, so that the entire temporary device can be moved inside the mine hole. At the same time, the rotating frame can be rotated to make the rotating frame drive the universal wheel to be in a vertical state, and the fourth hydraulic push rod drives the bottom pad to lift the fixed support, and the fifth hydraulic push rod drives the limiting slide to slide on the inner side of the limiting groove, so that multiple universal wheels can support the fixed support, and the fourth hydraulic push rod moves up the bottom pad, so that the temporary support device can be pushed to achieve lateral movement;

[0017] S2. When moving to the corresponding location, the positions of the fixed plate, the rotating plate and the connecting plate are adjusted by driving the second hydraulic push rod and the third hydraulic push rod, and the auxiliary top frame is driven to rotate by the hydraulic cylinder, so that the auxiliary top frame hinged at the lower end of the fixed top frame can be extended from the lower end of the fixed top frame, so that the volume of the entire temporary support device can be adjusted, so that the entire temporary support device can adapt to different mines for temporary support;

[0018] S3. When rockfall occurs, guide strips can be set to guide the rockfall and allow it to fall on the unloading roller. The unloading roller with an elastic structure can then alleviate the impact of the rockfall. At the same time, the horizontal decomposition of the gravity exerted by the rockfall will force the rockfall to move along the unloading roller, thereby achieving buffering of the falling rock.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting up a special crawler travel structure in conjunction with the lateral moving structure, the entire temporary support device for geological exploration flat tunnel excavation can be quickly and efficiently moved in the horizontal and vertical directions in the mine tunnel, thereby improving the construction efficiency of the protective structure.

[0021] 2. A driving motor is set to drive the matching wheel to rotate, so as to drive the connecting track to rotate through the matching wheel and the meshing block, and the entire temporary device can be moved inside the mine. At the same time, the rotating frame can be rotated to make the rotating frame drive the universal wheel to be in a vertical state, and the fourth hydraulic push rod is used to drive the bottom pad to lift the fixed support. At the same time, the fifth hydraulic push rod is used to drive the limiting slide to slide on the inner side of the limiting groove, so that multiple universal wheels can support the fixed support, and the fourth hydraulic push rod is used to move the bottom pad upward, so that the temporary support device can be moved horizontally by pushing the fixed support, thereby greatly improving the use convenience of the entire temporary support device.

[0022] 3. When rockfall occurs, guide strips can be set to guide the rockfall and allow it to fall on the unloading roller. The unloading roller with an elastic structure can then alleviate the impact of the rockfall. At the same time, the horizontal decomposition of the gravity exerted by the rockfall will force the rockfall to move along the unloading roller to achieve buffering of the falling rock. This can improve the safety of the entire temporary support device to a certain extent, and thus greatly improve the working efficiency of the entire temporary support device.

[0023] 4. The distance between the two groups of support assemblies is adjustable. The positions of the fixed plate, the rotating plate and the connecting plate are adjusted by driving the second hydraulic push rod and the third hydraulic push rod, so that the volume of the supporting structure of the temporary support device can be adjusted. At the same time, the distance adjustment structure of the support assembly cooperates with the movable hinge setting of the fixed top frame and the auxiliary top frame, so that the temporary support device is easy to disassemble, assemble and transport, and the support form can be adjusted as a whole. If necessary, the support device can be adapted to different mine cave forms and structural changes by increasing the number of auxiliary top frames and adjusting the stroke of the hydraulic cylinder and the hydraulic push rod.
