[0012] 1. The utility model is provided with a connecting component. After the construction personnel climb onto the steel mesh, they move the T-shaped rod toward the periphery of the winding box. The movement of the T-shaped rod drives the moving block to move. The movement of the moving block squeezes the connecting spring, and then pulls the binding belt toward the periphery of the winding box, and binds the binding belt to the construction personnel. When the construction personnel subsequently move on the steel mesh to perform construction operations, the movement of the construction personnel drives the binding belt to move, the movement of the binding belt drives the connecting belt to move, and the movement of the connecting belt drives the winding rod to rotate. Under the action of the connecting belt and the binding belt, the construction personnel can be bound and connected to prevent the construction personnel from falling off the steel mesh during the construction process.

[0013] 2. The utility model is provided with an observation water injection component. When the mobile water tank supplies water to the drilling rig for blasting operations, the remaining water amount inside the mobile water tank is reduced, and the float rod moves downward accordingly. During the downward movement of the float rod, the fixed mesh tube can provide a guide for the movement of the float rod. The downward movement of the float rod drives the top ball to move downward. When the top ball moves down and approaches the mobile water tank, the installation plate is taken out from the inside of the water injection port. The movement of the installation plate drives the sealing ring away from the sealing groove, and then water is added to the inside of the mobile water tank through the water injection port, so that the operator can observe the remaining water amount inside the mobile water tank and add water to the inside of the mobile water tank in time.

[0027] By adopting the above technical solution, when the construction personnel stand on the steel mesh 2 to perform construction operations, they first release the limiting effect of the limiting member 75 on the binding belt 74, then pull the binding belt 74 toward the periphery of the winding box 71, and bind the binding belt 74 to the construction personnel. When the construction personnel subsequently move on the steel mesh 2 to perform construction operations, the movement of the construction personnel drives the binding belt 74 to move, the movement of the binding belt 74 drives the connecting belt 72 to move, and the movement of the connecting belt 72 drives the winding rod 73 to rotate. Under the action of the connecting belt 72 and the binding belt 74, the construction personnel can be bound and connected to prevent the construction personnel from falling off the steel mesh 2 during the construction process.

[0033] Example 2

[0034] The present embodiment is different from the embodiment 1 in that: the water injection assembly 9 includes a floating rod 92, a top ball 93, a mounting plate 94, a sealing ring 95 and a water injection port 96. The water injection port 96 is arranged above the mobile water tank 8, the mounting plate 94 is arranged inside the water injection port 96, the outer wall of the mounting plate 94 is connected with a sealing ring 95, a sealing groove is arranged on the inner wall of the water injection port 96 and at a position corresponding to the sealing ring 95, the mounting plate 94 is plugged with a floating rod 92, one end of the floating rod 92 is connected with a top ball 93,

[0035] Specifically, a fixing ring is connected to the inner wall of the mobile water tank 8 and the periphery of the floating rod 92, and a fixing net cylinder 91 is connected between the mobile water tank 8 and the fixing ring.

During the downward movement of the float rod 92, the fixed mesh tube 91 can provide a guide for the movement of the float rod 92. The downward movement of the float rod 92 drives the top ball 93 to move downward. When the top ball 93 moves downward and approaches the mobile water tank 8, the mounting plate 94 is taken out from the water injection port 96. The movement of the mounting plate 94 drives the sealing ring 95 away from the sealing groove, and then water is added to the mobile water tank 8 through the water injection port 96, so that the operator can observe the remaining water amount in the mobile water tank 8 and add water to the mobile water tank 8 in a timely manner.

[0038] Working principle and use process of the utility model: During the construction of a small-section tunnel of the utility model, a small agricultural vehicle 5 is first used to move the entire device to the construction position, and then the hydraulic support legs 4 are used to support the entire device. After the construction personnel climb onto the steel mesh 2, they move the T-shaped rod 753 to the periphery of the winding box 71. The movement of the T-shaped rod 753 drives the moving block 755 to move inside the top frame 752. The moving block 755 moves to squeeze the connecting spring 754. When the T-shaped rod 753 is away from the side block 751, the binding belt 74 is pulled to the periphery of the winding box 71, and the binding belt 74 is pulled to the periphery of the winding box 71. The binding belt 74 is tied to the construction workers. When the construction workers move on the steel mesh 2 to perform construction operations, the construction workers move to drive the binding belt 74 to move, and then the child Velcro 76 is bonded to the parent Velcro 77, so that the binding belt 74 can be fixed. The movement of the binding belt 74 drives the connecting belt 72 to move, and the movement of the connecting belt 72 drives the winding rod 73 to rotate. Under the action of the connecting belt 72 and the binding belt 74, the construction workers can be bound and connected to prevent the construction workers from falling off the steel mesh 2 during the construction process, and then excavating and drilling small-section tunnels. And charge and connect, then use small agricultural vehicle 5 to move the whole device back to a safe place, detonate again, blast once, after slag discharge, use small agricultural vehicle 5 to move the whole device to the excavation surface, start to use horizontal steel pipe 1, vertical steel pipe 3 and inclined steel pipe 6 to apply initial support, and carry out the next cycle of excavation and drilling operation at the same time. During the excavation and drilling process, use external water supply equipment to transport the water in the mobile water tank 8 to the position of the drilling rig for drilling and blasting operation, which can meet the construction water demand of drilling and blasting. When the mobile water tank 8 supplies water to the drilling rig for drilling and blasting operation, As the remaining water amount inside the mobile water tank 8 decreases, the float rod 92 moves downward accordingly. During the downward movement of the float rod 92, the fixed mesh tube 91 can provide a guide for the movement of the float rod 92. The downward movement of the float rod 92 drives the top ball 93 to move downward. When the top ball 93 moves downward and approaches the mobile water tank 8, the mounting plate 94 is taken out from the water filling port 96. The movement of the mounting plate 94 drives the sealing ring 95 away from the sealing groove, and then water is added to the mobile water tank 8 through the water filling port 96, so that the operator can observe the remaining water amount inside the mobile water tank 8 and add water to the mobile water tank 8 in a timely manner.
