[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0022] This utility model proposes a concrete lining machine, which aims to solve the problem that existing concrete lining machines cannot adapt to construction conditions with slope lengths of different lengths.

[0023] like Figure 1As shown, the concrete lining machine includes an upper traveling mechanism 1, a lower traveling mechanism 2, a telescopic box girder 3, a plate-type telescopic hopper 4, and a concrete placement system 5. The upper traveling mechanism 1 and the lower traveling mechanism 2 can travel along the ground. The two ends of the telescopic box girder 3 are hinged to the upper traveling mechanism 1 and the lower traveling mechanism 2, respectively, and the telescopic box girder 3 can extend or shorten in a first direction. The plate-type telescopic hopper 4 is installed on the telescopic box girder 3, and the plate-type telescopic hopper 4 can extend or shorten synchronously with the telescopic box girder 3. The concrete placement system 5 is installed on the telescopic box girder 3, and the concrete placement system 5 can transport concrete to the plate-type telescopic hopper 4. In this embodiment, the construction ground is a slope. In actual operation, the upper traveling mechanism 1 and the lower traveling mechanism 2 can adjust their spacing according to different working conditions, while the telescopic box girder 3 can extend or shorten to adapt to the spacing between the upper traveling mechanism 1 and the lower traveling mechanism 2. Thus, during construction, the length of the telescopic box girder 3 can adapt to changes in the construction site. Furthermore, the insert-type telescopic hopper 4 can extend and retract synchronously with the telescopic box girder 3, and the concrete is transported to the insert-type telescopic hopper 4 through the material placement system 5 for lining the construction ground. This effectively solves the problems of concrete flow and overflow during lining due to misalignment of the telescopic hoppers. The telescopic box girder 3 can better adapt to slopes of different lengths and gradients; the insert-type telescopic hopper 4 can move with the telescopic box girder 3; the upper traveling mechanism 1 and the lower traveling mechanism 2 can move and adjust their spacing according to the slope length; the material placement system 5 can flexibly place materials as needed, making it more convenient and faster. The concrete lining machine in this embodiment is more efficient, stable, and adaptable for concrete lining on slopes.

[0024] See also Figure 2Specifically, the telescopic box girder 3 includes an upper truss 3.1, a lower truss 3.2, and a tail frame 3.3. The upper truss 3.1 is hinged to the upper traveling mechanism 1, and the upper truss 3.1 is slidably fitted to the lower truss 3.2. One end of the tail frame 3.3 is hinged to the lower truss 3.2, and the other end is hinged to the lower traveling mechanism 2. The insert-type telescopic hopper 4 includes an upper hopper 4.1, a lower hopper 4.2, and hopper partitions 4.3. The upper hopper 4.1 is connected to the upper truss 3.1, and the upper hopper 4.1 is slidably fitted to the lower hopper 4.2. The lower hopper 4.2 is connected to the lower truss 3.2. The lower hopper 4.2 is provided with a plurality of hopper partitions 4.3 spaced apart along a first direction, and the hopper partitions 4.3 are detachable. The upper truss 3.1 is mounted over the lower truss 3.2 and slides with it via rails and rollers. The lower surface of the telescopic box girder 3 also serves to smooth the concrete. One end of the tail frame 3.3 is hinged to the lower truss 3.2 via four pins, and the other end is hinged to the lower traveling mechanism 2. Both the upper and lower storage bins 4.1 are connected to the ground. The lower storage bin 4.2 is mounted over the upper storage bin 4.1 and slides with it. The upper storage bin 4.1 is fixedly connected to the bottom wall of the upper truss 3.1 via a horizontal flange 4.7, and the lower storage bin 4.2 is fixedly connected to the side wall of the lower truss 3.2 via a vertical flange 4.8. The coaxial arrangement of hopper 4.1 and discharge hopper 4.2 facilitates material loading, improves concrete paving, and effectively prevents concrete leakage. The upper traveling mechanism 1 and lower traveling mechanism 2 can drive the telescopic box girder 3 to extend and retract, thereby changing the length of the construction ground. The telescopic box girder 3 simultaneously drives the extension and retraction of the insert-type telescopic hopper 4, and adjusts the number of hopper partitions 4.3 according to the length after extension and retraction to ensure uniform concrete distribution within the insert-type telescopic hopper 4, guaranteeing the lining construction effect. This solves the problem of the non-coaxial arrangement of the upper hopper 4.1 and discharge hopper 4.2, saves lateral space in the equipment, and makes it more adaptable in concrete construction projects.

[0025] See also 3 to 4. Figure 4 The unloading hopper 4.2 forms a cavity 4.2.1, and the loading hopper 4.1 slides within the inner wall of the cavity 4.2.1. Multiple slots 4.2.2 are formed on the inner wall of the cavity 4.2.1. The two side edges of each hopper partition 4.3 are inserted into the slots 4.2.2 to divide the cavity 4.2.1 into multiple first hopper bodies A1. Limiting blocks are provided on the inner wall of the cavity 4.2.1. The side of each limiting block facing away from the cavity 4.2.1 forms a vertically arranged slot 4.2.2. Multiple limiting blocks are arranged in pairs facing each other. The two side edges of each hopper partition 4.3 are inserted into the slots 4.2.2 of two opposing limiting blocks to divide the cavity 4.2.1. The operation is simple and disassembly is convenient.

[0026] In this embodiment, the cavity 4.2.1 is divided into two small hoppers and one large hopper. The feeding hopper 4.1 is slidably disposed within the large hopper. When the insert-type telescopic hopper 4 is not extended, the large hopper is not exposed, and the small hoppers cooperate with the second hopper 4.1.1 of the feeding hopper 4.1 for lining construction. When the insert-type telescopic hopper 4 needs to be extended, the exposed portion of the large hopper is divided into multiple first hoppers A1 by the hopper partition 4.3. At this time, the small hoppers, the first hoppers A1, and the second hopper 4.1.1 cooperate for lining construction. The insert-type telescopic hopper 4 in this embodiment can adapt to lining construction on construction grounds of different lengths.

[0027] Further, see Figure 5 The slide-type telescopic hopper 4 also includes rubber baffles 4.4. Both the upper hopper 4.1 and the lower hopper 4.2 have detachably installed rubber baffles 4.4 along a first direction at their bottoms. These rubber baffles 4.4 are used to seal the gaps between the upper hopper 4.1 and the lower hopper 4.2 and the ground. The rubber baffles 4.4 are located at the edges of the upper hopper 4.1 and the lower hopper 4.2, and they overlap to prevent interference during expansion and contraction. The rubber baffles 4.4 effectively seal the gaps between the upper hopper 4.1 and the lower hopper 4.2 and the ground, preventing concrete leakage from the sides and ensuring construction effectiveness.

[0028] The rubber baffle 4.4 comprises multiple spliced ​​rubber plates 4.4.1 arranged sequentially along a first direction. During construction, the rubber baffle 4.4 needs to continuously rub against the ground. Due to the varying degrees of ground undulation, some areas wear out faster and are prone to concrete leakage. The rubber baffle 4.4 uses multiple spliced ​​rubber plates 4.4.1 continuously spliced ​​together to facilitate direct replacement of spliced ​​rubber plates 4.4.1 in severely worn areas, which helps save costs.

[0029] Furthermore, the feeding hopper 4.1 contains multiple second hoppers 4.1.1 spaced apart along the first direction, with the second hoppers 4.1.1 having the same dimensions as the first hopper A1. The insert-type telescopic hopper 4 also includes a vibrator 4.5, which can be detachably installed in both the first hopper A1 and the second hopper 4.1.1. The hopper partitions 4.3 are all provided with mounting holes for fixing the vibrator 4.5, allowing for the installation of the vibrator 4.5 as needed. The vibrator 4.5 enables the concrete to be compacted, eliminating honeycomb and pitting phenomena, and improving strength.

[0030] In addition, the outer wall of the discharge hopper 4.2 is equipped with hooks 4.6, and the hopper partition 4.3 can be hung on the outer wall of the discharge hopper 4.2 via the hooks 4.6. Unused hopper partitions 4.3 can be hung on the hooks 4.6 on the discharge hopper 4.2 for easy storage and retrieval.

[0031] In this embodiment, the upper traveling mechanism 1 and the lower traveling mechanism 2 have the same structure. The upper traveling mechanism 1 includes a support body, a traveling drive component, a lifting platform, and a lifting outrigger assembly. The bottom of the support body is equipped with traveling wheels, which allow the support body to travel along the ground. The traveling drive component is mounted on the support body, and its output end is connected to the traveling wheels. The lifting platform is slidably mounted on the support body in the vertical direction and is hinged to the telescopic box girder 3. The lifting outrigger assembly is vertically mounted on the bottom of the lifting platform and can extend or shorten in the vertical direction. The lifting outrigger assembly is used to contact the ground. The lifting outrigger assembly supports four lifting outriggers located at the four corners of the lifting platform. Tracks for the upper traveling mechanism 1 and the lower traveling mechanism 2 are respectively provided on both sides of the construction ground. When the upper traveling mechanism 1 and the lower traveling mechanism 2 travel along the tracks, each lifting outrigger shortens to move away from the ground. After reaching the designated position, the lifting outriggers extend to contact the ground for auxiliary support. They can also continue to extend according to different working conditions to drive the lifting platform upward, thereby adapting to different lining thicknesses. The upper traveling mechanism 1 and the lower traveling mechanism 2 can move and move up and down, and the corresponding spacing and angle can be adjusted according to the length and angle of the slope. The upper traveling mechanism 1 and the lower traveling mechanism 2 are respectively equipped with the upper operating platform 1.1 and the lower operating platform 2.1, which are mainly used to control the operation of the entire equipment.

The frame is located on the upper truss 3.1, and the conveying drive is located on the frame. The upper belt 5.1.1 is located on the frame and connected to the output end of the conveying drive; the upper belt 5.1.1 is used to convey concrete. The upper feeding trolley 5.1.2 is slidably located on the frame along a first direction and can deliver the concrete from the upper belt 5.1.1 into the insert-type telescopic hopper 4. The concrete placement system 5 mainly consists of the upper placement mechanism 5.1 and the lower placement mechanism 5.2. The upper concrete placing mechanism 5.1 is fixed to the top surface of the upper truss 3.1, and the lower concrete placing mechanism 5.2 is fixed to the lower truss 3.2. The upper concrete placing mechanism 5.1 mainly consists of an upper belt 5.1.1 and an upper feeding trolley 5.1.2.
