At the same time, as the rock drilling work gradually deepens, the traditional payment equipment has defects in the payment work, such as:

[0003] Traditional shaft anchor spraying support construction uses manual air drills to drill holes and manual spray heads for grouting. When the excavation depth exceeds 4m, work can only be done on a hanging platform. The overall working environment is affected by aspects such as the drilling angle, making it difficult to ensure the quality of the drilling. Different types of rock drilling equipment may have limitations when adapting to different geological conditions, and it is difficult to meet the needs of shaft construction in complex geological environments. The use of a supporting spray head for spraying affects the working scope during work by the hanging platform working environment.

[0063] A hydraulic pipe guide frame 14 is installed at the other end of the drilling rig slide 10. The hydraulic pipe guide frame 14 is composed of a U-shaped metal support and three rollers installed in a triangle, and the rollers rotating inside the hydraulic pipe guide frame 14 are in contact with the pipes of the hydraulic station 5;

[0064] A telescopic cylinder 15 is installed in the main support beam 9, and the telescopic cylinder 15 is connected to the bottom end of the drilling rig slide 10;

[0065] The carriage support beam 16 is installed at the bottom end of the main support beam 9, and a rotating support is provided at the connection between the bottom end of the carriage support beam 16 and the support bottom plate 8, and an adjusting compensation oil cylinder 21 is rotatably connected at the steel frame opening between the bottom end of the carriage support beam 16 and the support bottom plate 8, and the adjusting compensation oil cylinder 21 is arranged in an inclined shape;

[0066] A rocker 17 is installed at the bottom of the carriage support beam 16, and the rocker 17 is arranged at the bottom of the carriage support beam 16 near the rock drilling end of the rock drilling rod 12. The limiting metal clamps 18 are symmetrically installed on both sides of the rocker 17, and a grouting nozzle pipe 20 is placed in the opening of the limiting metal clamp 18. A positioning limiter 19 is sleeved on the surface of the limiting metal clamp 18, and the positioning limiter 19 is a double-layer rotatably connected annular structure, and one side of the positioning limiter 19 is against the surface of the grouting nozzle pipe 20;

[0067] In conjunction with the accompanying drawings Figure 1-Figure 10 As shown, the rock drilling and grouting assembly is installed between the working connection frame 7 installed on the turntable plate surface at the output end of the turntable 6 and the supporting bottom plate 8, as shown in FIG. Figure 1-Figure 4 As shown, when rock drilling is carried out, the externally connected crane or other traction equipment lifts the upper hanging plate 1 and the lower hanging plate 3 to the appropriate position, then starts the hanging plate stabilizing cylinder 4 to fix the hanging plate and maintain stability, and the compensation cylinder 21 is connected to the bottom end of the slide support beam 16. When in use, the slide support beam 16 rotates the support at the bottom end to support and adjust the angle of the rock drilling rod 12 during operation for compensation. The main support beam 9 located at the top of the slide support beam 16 provides installation assistance for the telescopic cylinder 15. When in use, the telescopic cylinder 15 drives the drilling rig slide 10 to move to cooperate with the rock drilling rod 12 to adjust the rock drilling working depth. The rock drilling rod 12 installed on the slide of the drilling rig slide 10 pushes the rock drilling rod 12 to the specified direction for rock drilling. The drill rod guide 13 located at the output end of the rock drilling rod 12, as shown in FIG. Figure 8As shown in the installation, the bearing structure located inside the drill rod guide 13 assists the rotation of the rock drilling rod 12 and guides the rock drilling depth. After the drilling of the rock drilling rod 12, the precise processing of the shaft position is achieved. When the vertical shaft is used for shotcrete operation, the externally connected crane and other traction equipment lift the upper hanging plate 1 and the lower hanging plate 3 to a suitable position, and then the hanging plate stabilizing cylinder 4 is started to fix the hanging plate to maintain stability. The support base plate 8 is rotated by the turntable 6 to adjust the angle of the whole. After the shotcrete nozzle pipe 20 is connected to the working shotcrete machine and started, the limiting metal clamps 18 on both sides of the rocker 17 drive the nozzle part of the shotcrete nozzle pipe 20 to operate, and the turntable 6 is controlled to rotate the shotcrete position.

After one circle of spraying is completed, the hanging plate stabilizing cylinder 4 is retracted and the hanging plate is lowered to the next position to continue spraying. During the spraying operation, the distance angle between the spraying nozzle pipe 20 and the rock surface is basically always within 75°, and the rebound amount of the shotcrete is controlled, thereby reducing the risk factor of the operation.

[0068] Working principle: When using the integrated rock drilling and grouting equipment of the shaft anchor spraying support, firstly, the upper hanging plate 1, the pulling column 2 and the lower hanging plate 3 form a double-layer payment frame structure, and the device is installed as a whole at the rock drilling position of the shaft construction through the hanging plate stabilizing cylinder 4. The protective turning platform 22 located between the upper hanging plate 1 and the lower hanging plate 3 rotates to adjust the opening position, so that the staff can enter the equipment through the guide ladder 23 for daily maintenance and inspection. The positioning plate frame 24 located at the top of the protective turning platform 22 and the guide ladder 23 is connected with the metal steel frame used for external support and the corresponding lifting hanger to provide traction protection for the work of the device. The turntable 6 is driven by the store to drive the turntable at the output end and the hydraulic rock drill 11 below to rotate and adjust the appropriate angle and direction to the vertical shaft drilling position for processing. The drill rod guide 13 guides the rock drilling drill rod 12 in the opposite direction, and the drilling rig slide 10 pushes the hydraulic rock drill 1 to the rock drilling depth of the shaft surface. 1 The work is refined. The carriage support beam 16 located at the bottom of the main support beam 9 assists in controlling the rock drilling angle under the adjustment of the compensating oil cylinder 21 to realize the rock drilling work. When the shotcrete operation is carried out, the height of the lifting device of the external lifting equipment of the hoisting plate stabilizing oil cylinder 4 is retracted so that the shotcrete nozzle pipe 20 reaches the working height. The hoisting plate stabilizing oil cylinder 4 is opened and rooted again. The turntable 6 is used to adjust the main range of shotcrete. The rocker 17 located at the bottom of the carriage support beam 16 drives the shotcrete nozzle pipe 20 clamped inside the limiting metal clamp 18 to provide shotcrete operations in different directions in the shaft under the rotation of the turntable 6. When the shotcrete nozzle pipe 20 is operating, the nozzle is basically always at a distance angle of less than 75° from the rock surface, and the shotcrete rebound amount is controlled. By assembling the rock drilling and shotcrete working equipment, the working rhythm of rock drilling and shotcrete is smooth, and the rebound amount generated by the shotcrete work is further controlled, thereby improving the working efficiency and reducing the labor intensity and working risk factor of the workers.
