Two oil cylinders 9, the telescopic end of the second oil cylinder 9 is rotatably connected to the rear side of the electric rotating seat 7, a positioning sleeve 10 is provided on the rear side of the electric rotating seat 7, a movable arm 11 is bolted to the rear side of the positioning sleeve 10, the front side of the movable arm 11 is bolted to the rear side of the electric rotating seat 7, the bottom of the rear side of the electric rotating seat 7 is rotatably connected to the third oil cylinder 12, the telescopic end of the third oil cylinder 12 is rotatably connected to the positioning sleeve 10, the interior of the positioning sleeve 10 is a groove, a spray pipe 13 is provided inside the positioning sleeve 10, positioning components 14 are provided on both sides of the interior of the positioning sleeve 10, and the positioning component 14 is located on the outside of the spray pipe 13.

[0028] The tunnel safety mechanical arm 5 structure provided above, when it is necessary to spray a specific area on the top of the tunnel, the operator controls the electric wheel 2 and the direction adjustment seat 3 to make the mechanical arm 5 roughly align with the area, and then drives the extension of the first cylinder 6 to lift the mechanical arm 5, and then starts the electric rotating seat 7 to rotate the cross arm 8 to a suitable angle, so as to quickly switch the spraying area and improve the construction efficiency, and extend the second cylinder 9 to extend the cross arm 8, and then adjust the angle of the movable arm 11 through the third cylinder 12, so that the positioning sleeve 10 located at the rear side of the third cylinder 12 and the movable arm 11 can achieve synchronous angle adjustment. In this process, the positioning component 14 located inside the positioning sleeve 10 positions the spraying pipe 13, and then transports concrete slurry to its spraying pipe 13, so as to ensure that the concrete slurry can be accurately and evenly sprayed onto the construction surface, improve the adhesion quality of the spraying, and avoid the slurry from falling, so as to ensure the safety and efficiency of the construction.

[0029] In this embodiment, the positioning assembly 14 includes a screw rod 1401, a clamping plate 1402 and a rotating rod 1403. The screw rod 1401 is threadedly connected to both sides of the positioning sleeve 10, and the clamping plates 1402 are respectively arranged on both sides of the interior of the positioning sleeve 10. The outer side of the clamping plate 1402 is rotatably connected to the inner side of the screw rod 1401. The clamping plate 1402 is located on the outer side of the spray tube 13, and the rotating rod 1403 is welded to the outer side of the surface of the screw rod 1401; in this way, the operator can rotate the rotating rod 1403 to drive the screw rod 1401 to rotate, so that the clamping plate 1402 is loosened a little, and after adjusting the position of the spray tube 13, the rotating rod 1403 is rotated in the opposite direction to make the clamping plate 1402 clamp the spray tube 13 again to achieve an accurate spraying effect.

[0030] A push frame 15 is bolted to the front side of the load-bearing plate 1, and the push frame 15 is L-shaped; in this way, when the control of the electric wheel 2 at the bottom of the load-bearing plate 1 is not precise enough, the operator can push the push frame 15 by applying appropriate force to adjust the position of the load-bearing plate 1.

[0031] The top of the push frame 15 is covered with a protective cover 16, which is made of rubber material; in this way, the friction between the operator's hand and the top of the push frame 15 can be increased, so that the hand is not easy to slip when pushing the push frame 15, thereby improving the safety and stability of the operation.

[0032] The surface of the protective cover 16 is provided with anti-skid patterns in a grid shape; thus, when the operator's hand contacts the protective cover 16 , the grid patterns will generate more friction and resistance with the hand, facilitating use.

[0033] In this embodiment, a turntable 17 is fixedly welded to the outer side of the rotating rod 1403, and the turntable 17 is made of metal material; in this way, the operator can save effort and convenience when rotating the rotating rod 1403, and it is not easy to be damaged, thereby ensuring the reliability of operation.

[0034] The outer side of the turntable 17 is provided with anti-skid patterns in the shape of lines; in this way, the roughness of the surface of the turntable 17 can be effectively increased. When the operator holds the turntable 17 for rotation, the lines and patterns form more contact points and friction with the hand.

[0035] In this embodiment, a reinforcing pad 18 is bonded to the inner side of the clamping plate 1402, and the reinforcing pad 18 is made of elastic rubber material; in this way, it can better fit the shape of the spray pipe 13, increase the contact area, and thus improve the stability and reliability of clamping.

[0036] The inner side of the reinforcement pad 18 is provided with reinforcement lines, which are in the shape of double-layer lines; thus, the friction between the reinforcement pad 18 and the spray tube 13 is further increased, ensuring the stability of the spray tube 13 when it is positioned, so as to facilitate use.

[0037] In this embodiment, the top of the spray pipe 13 is connected to a regulating valve, and the top of the regulating valve is connected to a liquid guide tube; in this way, when it is necessary to increase the intensity and coverage area of ​​the spraying, the opening of the regulating valve can be increased to allow more concrete slurry to pass through the spray pipe 13, increasing the flow rate and pressure. Conversely, if fine local spraying or reducing material consumption is required, the opening of the regulating valve can be reduced.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
