Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a grouting system of an arch-anchor-grouting combined operation trolley. Background Art

[0002] During tunnel construction, a series of technical measures are often implemented to reinforce and support the ground to ensure the project's safety and stability. Anchor bolting is a very common and effective method. After installing the anchor bolts, grouting is often performed to further enhance their support. Currently, there are two common ways to obtain the required slurry for grouting: one is to connect a mixing station outside the tunnel to the work surface via a pipe, with the slurry supplied by the external mixing station; the other is to directly move the mixing equipment into the tunnel, requiring it to be continuously moved forward as tunnel construction progresses. Both methods present significant operational inconveniences. Because the ground conditions are often uneven during tunnel construction, each move of the mixing equipment requires additional time for placement and leveling. This not only increases the complexity of the operation but also significantly slows down the construction progress, significantly reducing overall efficiency.

[0003] A Chinese patent (publication number: CN217925939U) discloses an arch anchor trolley with a grouting function; the patent provides an inwardly recessed groove area on the side of the vehicle body, and a grouting machine is embedded in the groove area, and the grouting machine is connected to the vehicle body through a lifting assembly; in actual use, it was found that since the grouting machine was embedded in the side of the vehicle body, it was not convenient to feed materials and was inconvenient to use.

[0020] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", and "right" indicating directions or positional relationships, they are only corresponding to the drawings of the present application for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction.

[0021] Example 1, combined with the attached Figures 1 to 4 , a grouting system of an arch anchor grouting combined operation trolley, installed on one side of the bottom of the working platform 13. Figure 1 As shown, the system can be integrated on the working platform 13, which facilitates grouting operations during tunnel construction, does not occupy the working space on the working platform 13, and does not affect the normal operation of other working equipment on the working platform 13. The grouting system includes a telescopic slide 1, a mounting frame 2, a screw conveyor 3 and a stirring device. The two sides of the top of the mounting frame 2 are respectively connected to the bottom side of the working platform 13 by telescopic slides 1. A screw conveyor 3 for conveying slurry is provided at the bottom of the mounting frame 2, and a stirring device is provided above the screw conveyor 3. The discharge port of the stirring device is connected to the feed port of the screw conveyor 3 through a plug valve 4.

[0022] When grouting is required, the mounting frame 2 can be withdrawn via the telescopic slide 1, allowing the stirring device to be withdrawn and the mortar to be stirred. Once the mortar is stirred, the gate valve 4 is opened, allowing the mortar in the stirring device to flow into the screw conveyor 3. The discharge port of the screw conveyor 3 is connected to the grouting hose, allowing grouting operations to proceed. When the work platform 13 needs to be moved, the stirring device can be retracted to the bottom of the work platform 13 via the telescopic slide 1.

[0023] Combined with attachment Figure 2 The stirring device comprises an open-top housing 5, within which a stirring shaft 6 with stirring blades is rotatably connected at the bottom. The stirring shaft 6 is arranged horizontally. This design effectively reduces the overall height of the stirring device while ensuring stirring efficiency, making it easier to install at the bottom of a work platform 13. A drive device 7 is provided outside the housing 5 for driving the stirring shaft 6. The drive device 7 can be an electric motor or a hydraulic motor.

[0024] In order to further reduce the overall height of the stirring device and avoid splashing of mortar during the stirring process, an anti-splashing device is provided on the top of the box body 5. Figure 3 and 4As shown, the anti-splash device comprises a frame 8 connected to the top of the housing 5. Two inclined baffles 9 are spaced apart on either side of the frame 8. An inverted V-shaped baffle 10 is positioned in the middle of the frame 8, with the bottom edge of the inverted V-shaped baffle 10 extending between the two inclined baffles 9 on the corresponding side. The staggered arrangement of the inverted V-shaped baffles 10 and the inclined baffles 9 achieves anti-splash protection, thereby reducing the height of the housing 5 while preventing mortar from splashing. Furthermore, the anti-splash device does not need to be removed when adding materials to the housing 5, making operation more convenient.

[0025] The frame 8 is correspondingly plugged into the top of the box body 5, and a limiting rib 11 is provided on the outside of the frame 8, that is, the frame 8 is detachably connected to the top of the box body 5. The operator can regularly remove the anti-splash device and clean the mortar adhered to the anti-splash device.

[0026] In order to further improve the uniformity of the mortar, a vibrator 12 is provided at the bottom of the box 5. During the mixing operation, the vibrator 12 can be turned on to improve the uniformity of the mortar and improve the mixing efficiency.

[0027] A screen is provided on the top of the stirring device to prevent large particles or foreign matter from entering the stirring device, thereby avoiding accidental blockage of the gate valve 4 or the screw conveyor 3 during the grouting operation.

[0028] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
