Description

Technical Field

[0002] During the construction and maintenance of tunnels, it is usually necessary to inject mortar into the interior. Dense pressure grouting technology is a common and important means for reinforcing surrounding rock, filling cracks, preventing water leakage, etc., to ensure the structural stability, durability and waterproof performance of the tunnel. Usually, the grouting equipment needs to be moved into the tunnel using a tunnel vehicle, and the materials are mixed to form mortar and stored in the tunnel. At the same time, a grouting pump and a pressure transmitter are used to densely pressurize the stored mortar into the construction position of the tunnel. However, traditional button feeding equipment still has problems that need to be improved.

[0021] During the actual application of this embodiment: the staff can use the tunnel vehicle 1 to move the grouting equipment to the work site in the tunnel according to the actual needs, and use the screw rod 14 to inject the proportioned materials into the mixing barrel 3, so that the rotating rod 4 and the stirring plate 5 can stir and mix the materials in the mixing barrel 3 to form a slurry. After that, the staff needs to control the discharge valve 35 to open, so that the slurry in the mixing barrel 3 can be discharged through the discharge valve 35 under the action of gravity to be stored in the storage barrel 2.

[0022] As a preferred embodiment of the present invention, the delivery unit includes a dragon and a weighing unit, and the dragon includes: The transmission 12 is fixed to the lower end of the dragon shell, and the driving end is connected to the screw rod 14; The motor 13 is connected to the input end of the transmission 12 to drive the transmission 12 to operate; The lower end of the filling hopper 15 is connected to a solenoid valve 16 , and the solenoid valve 16 is communicated with the auger housing 11 .

[0023] Specifically, the mixing barrel 3 can provide stable support for the dragon shell, the auger shell 11 can support the transmission 12, the transmission 12 can provide support for the screw rod 14, and can drive the screw rod 14 to rotate, and the transmission 12 can also provide support for the motor 13, the motor 13 can drive the transmission 12 to operate, the transmission 12 can transmit rotational power to the screw rod 14, and can adjust the rotation speed as needed, the auger shell 11 can provide support for the filling bucket 15 through the solenoid valve 16, and the filling bucket 15 can provide a filling space for the material.

[0025] Specifically, the filling hopper 15 can provide a space for the insertion channel 17, and the insertion channel 17 can provide a space for the support plate 18 and the connecting plate 20 to be inserted, so that the filling hopper 15 can use the insertion channel 17 to provide support for the support plate 18. A through hole 22 is opened inside the support plate 18, and the switch 23 is located in the through hole 22. When the switch 23 is pressed, it will control the solenoid valve 16 to open.

After the gravity of a batch of materials meets the standard, the staff can insert their hands into the through port 22 and pull the supporting plate 18 in the direction away from the storage barrel 2, so that the supporting plate 18 drives the weighing sensor 19 and the connecting plate 20 to pass through the insertion channel 17 and the filling bucket 15 and move outward, thereby opening the filling bucket 15 and the filling bucket 15. The channel between the solenoid valves 16 allows the material on the connecting plate 20 to fall into the solenoid valve 16.

The inclined push plate 60 can use external force and its own inclination angle to rotate with the storage barrel 2 as the center after descending to push the elliptical rod 68 to move downward.

[0043] In actual application of this embodiment, when the controller 10 detects that the inlet pressure of the grouting pump 7 drops to a normal range, the connecting pipe 6 is blocked. Since there is a gap between the inlet diameter of the connecting pipe 6 and the amount of material in the storage cylinder, and mortar sediment may be adhered and accumulated in the connecting pipe 6, the position of the connecting pipe 6 near its own inlet is more likely to be blocked. The staff needs to control the extension of the electric rod 46 so that the electric rod 46 uses the telescopic end to push the elastic rod 50 downward, so that the elastic rod 50 is bent and deformed by the guidance and resistance of the arc hole rod 48 under the action of external force, and moves along the guide tube 49 to the inside of the connecting pipe 6. In this process, the elastic rod 50 The rod 50 will pull the spring 51 to deform and expand under the guidance of the guide tube 49 and the action of the external force of movement, so that the spring 51 gradually stretches and stores energy. When the electric rod 46 is fully extended, the sharp end of the elastic rod 50 will be inserted into the connecting tube 6, thereby pushing the mortar blocked in the connecting tube 6. At the same time, the electric rod 46 will use the telescopic end to pull the pull rope 58 during the extension process, so that the pull rope 58 passes through the through hole 56 and moves downward along the through hole 57, so that the pull rope 58 can use external force to pull the T plate 53, so that the T plate 53 drives the pressure plate 54 downward under the guidance of the T groove 52. At the same time, the T plate 53 will cooperate with the connecting rod 37 to squeeze the elastic rod 50 during the downward movement. The plate 55 bends and deforms and stores energy. During the downward movement, the pressure plate 54 contacts and squeezes the baffle 61, causing the baffle 61 to push the oblique push plate 60 downward through the guide hole 59 and move downward. At the same time, the baffle 61 squeezes the first spring 62 with the cooperation of the tooth block 33 to contract and store energy. After the electric rod 46 is extended, the inclined surface of the oblique push plate 60 moves to the side of the elliptical rod 68, and then the oblique push plate 60 uses its own inclination angle and the curvature of the elliptical rod 68 to push the elliptical rod 68 downward as the tooth block 33 and the N ring 30 rotate counterclockwise, so that the elliptical rod 68 can drive the hammer rod 67 to pass through the guide cylinder 64 and move downward together. , so that the lower end of the hammer rod 67 can contact and knock the connecting tube 6, and at the same time the hammer rod 67 will squeeze the second spring 66 through the retaining ring 65 to contract and store energy. When one of the inclined push plates 60 passes through the elliptical rod 68, the second spring 66 will rebound under the support of the guide cylinder 64, and push the hammer rod 67 and the elliptical rod 68 upward through the retaining ring 65 to move, so that the hammer rod 67 is separated from the connecting tube 6. Then, as the N ring 30 rotates, the next inclined push plate 60 will be used to push the elliptical rod 68, so that the hammer rod 67 can move back and forth up and down to knock the connecting tube 6, causing the connecting tube 6 to vibrate, thereby promoting the flow of mortar blocked in the connecting tube 6 and preventing blockage.

[0044] After the electric rod 46 contracts and resets, the elastic sheet 55 will use the rebound force to push the T-plate 53 and the pressure plate 54 upward to reset, and the first spring 62 will use the rebound force to push the baffle 61 and the inclined push plate 60 upward to reset. During the reset process of the T-plate 53, the pull rope 58 will be pulled to move and reset at the same time.
