[0032] In order to more clearly describe the specific structure of the tunnel grouting vehicle with lifting frame, Figure 1-5 Describe this embodiment:

[0033] like Figure 1 and Figure 2As shown, a tunnel grouting vehicle with a lifting frame includes a grouting vehicle 1 and a stand 2 installed on the grouting vehicle 1. The top of the stand 2 is provided with a frame plate and a telescopic guardrail; the frame plate includes a fixed plate 3 fixed to the top of the stand 2 and a movable plate 4 hinged to the outer end of the fixed plate 3. The stand 2 is provided with a movable plate 4 that can keep the movable plate 4 in a horizontal working state ( Figure 1 ) or tilted storage state ( Figure 2 ) a first support member;

[0034] See Figure 4 The telescopic guardrail is rectangular as a whole, with two opposite sides being the telescopic parts 5 and the other two opposite sides being the translation parts 6. The middle section of the telescopic part 5 is fixed to the upper surface of the fixed plate 3. A second support member is provided on the stand 2. The second support member drives the two translation parts 6 to move relative to or away from each other. The two telescopic parts 5 are extended and retracted as the two translation parts 6 move. When the movable plates 4 on both sides are kept in a horizontal working state, the two translation parts 6 of the telescopic guardrail move away from each other to a position where they are buckled with the outer end of the corresponding movable plate 4 (the end away from the fixed plate 3).

[0035] exist Figure 1 In the working state shown, the movable plates 4 on both sides are flattened under the action of the first support member and are on the same plane as the fixed plate 3. After the translation parts 6 on both sides are pulled, the telescopic parts 5 become longer and the translation parts 6 move to the outer ends of the movable plates 4. At this time, people can stand on the upper surface of the movable plates 4, and the protection range of the telescopic guardrail is also increased. In the non-construction state, construction personnel need to stand on the frame plate. At this time, the frame plate and the telescopic guardrail can be retracted. Figure 2 In the retracted state, the movable plates 4 on both sides are flipped and drooped, and the length of the entire frame plate is greatly reduced. In the retracted state, the telescopic guardrail is located on the fixed plate 3 as a whole, and there is space on the fixed plate 3 for placing grouting pipe joints, electric drills and other equipment.

[0036] The telescopic portion 5 may specifically be a diamond-shaped telescopic frame.

[0037] Specifically, for ease of description, the telescopic portion 5 may be connected to the fixed plate 3 via a fixed rod 16 , the fixed rod 16 and the fixed plate 3 remain stationary, and other portions of the telescopic guardrail may be movable.

[0038] See Figure 3 In the above embodiment, the first support member is the first electric telescopic rod 7 , one end of the first electric telescopic rod 7 is hinged to the stand 2 , and the other end is hinged to the bottom surface of the movable plate 4 .

[0039] See Figure 1 and Figure 2The second support member includes a second electric telescopic rod 8, a slide 9 and an oblique support rod 10; the slide 9 is vertically slidably arranged on the side of the stand 2, the lower end of the second electric telescopic rod 8 is fixed to the stand 2, and the upper end is fixed to the bottom surface of the slide 9. The two sides of the slide 9 are rotatably connected to the oblique support rod 10, and the outer end of the oblique support rod 10 is rotatably connected to the corresponding translation part 6. The function of the second electric telescopic rod 8 is to adjust the height of the slide 9 on the stand 2. The slide 9 is Figure 1 The middle height is higher, and at this time the inclination angle of the diagonal support rod 10 is smaller and the lateral width is larger, which can make the telescopic part 5 in an extended state. During the downward movement of the slide 9, the inclination angle of the diagonal support rod 10 gradually increases and the lateral width decreases, so that the distance between the two translation parts 6 and the length of the telescopic part 5 are reduced.

[0040] See Figure 5 In order to improve the stability of the connection between the frame plate and the telescopic guardrail in the horizontal working state, a socket 11 is fixed at the outer end of the movable plate 4. The socket 11 has a horizontal slot, and a horizontal insertion rod 12 that cooperates with the slot is fixed on the side of the translation part 6. During operation, the two movable plates 4 are first flattened, and then the translation part 6 is controlled to translate outward until the horizontal insertion rod 12 is stuck in the slot of the socket 11.

[0041] See 1 or Figure 2 In order to adapt to tunnels of different heights, the stand 2 is slidably connected to the frame on the grouting vehicle 1. A vertical lifting cylinder 13 is fixed on the grouting vehicle 1. The telescopic arm of the lifting cylinder 13 is fixedly connected to the side of the stand 2. The stand 2 is driven up and down by the lifting cylinder 13, thereby adjusting the height of the entire frame.

[0042] See Figure 1 、 Figure 2 or Figure 4 A ladder 14 is provided on the body of the grouting vehicle 1 near the fixed plate 3, and construction workers climb up to the flattened frame plate via the ladder.

[0043] See Figure 1 or Figure 2 On both sides of the body of the grouting vehicle 1, work support rods 15 for supporting the ground are provided, and pads are fixed on the telescopic arms of the work support rods 15. The work support rods 15 can specifically adopt hydraulic cylinders. Before construction, the pads can be extended to contact the ground to increase the contact area with the ground and ensure stability during the operation.

[0044] In order to maintain the stability of the electric telescopic rod, air cylinder and hydraulic cylinder in the working state, all three are equipped with a self-locking function.

[0045] The grouting vehicle 1 can be an ordinary engineering vehicle, which can carry slurry for grouting and deliver the slurry to the top of the tunnel through a pump and a grouting pipe. The joint of the grouting pipe is placed on the fixed plate 3, and the construction worker connects the grouting pipe joint to the grouting hole at the top of the tunnel. A controller for controlling the telescopic rod and cylinder and a power supply battery are set in the car or cab of the grouting vehicle.
