DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] The present invention is a concrete distribution vibrating lining slipform machine, which is used for lining slipform construction of concrete pavement. The slipform machine is suitable for vibrating, extruding and slipform forming of dry and hard concrete materials with large pouring thickness in tunnels, bridges, roads, airports, etc. It has the characteristics of compacting by vibration, no segregation, no water seepage, making the poured concrete harden faster and having higher strength, etc.

[0024] like Figure 1 , Figure 2As shown, the concrete spreading and vibrating lining slipform machine comprises a walking mechanism 1, a box beam, a feeding mechanism, a spiral distributing mechanism, a vibrating mechanism and a slipform forming mechanism. The walking mechanism 1 is used to drive the whole machine to move forward longitudinally. The direction of the machine's movement is the longitudinal direction, and the direction horizontally perpendicular to the longitudinal direction is the transverse direction. The box beam acts as a support frame for the whole machine. The feeding mechanism, the spiral distributing mechanism, the vibrating mechanism and the slipform forming mechanism are arranged in sequence from front to back. The feeding mechanism, the feeding mechanism, the spiral distributing mechanism, the vibrating mechanism and the slipform forming mechanism are all arranged on the box beam. The feeding mechanism transports the concrete falling from the tank truck or the pump truck, and transports it backward to the spiral distributing mechanism to transport the concrete material. The concrete material is transported to both sides of the transverse direction through the bolt distributing mechanism to ensure that the concrete material is evenly spread. A vibrating mechanism is arranged behind the spiral distributing mechanism, and the vibrating mechanism is used to vibrate and compact the concrete after spreading. The slipform forming mechanism performs slipform forming on the road surface. The slipform forming mechanism mainly includes a template fixed behind the vibrating mechanism for slipform forming, and the shape of the pavement slipform forming is controlled by the template.

[0025] The box beam is installed on the traveling mechanism 1 through the lifting mechanism 2, and the box beam can be raised and lowered by the lifting mechanism 2. Usually, the lifting mechanism 2 is a hydraulic cylinder. The lifting mechanism drives the whole machine to rise and fall, and the frame can be raised and lowered at any time during the construction process to adjust the construction of different thicknesses to achieve the required paving and pouring elevation requirements.

[0026] The walking mechanism 1 is preferably a crawler walking mechanism, which reduces the pressure on the ground during walking and increases the friction, and the crawler walks on the bottom plate cushion layer.

[0027] The slide forming mechanism is an important forming component of the machine. The slide forming mechanism realizes slide forming through a template. A primary forming template 3 can be set as needed. If higher quality slide forming is required, a primary forming template 3 and a finalizing template 4 can be set. The primary forming template 3 is used for forming first, and then the finalizing template 4 is used for correction and finalization. Figure 7 , Figure 8 shown.

[0028] The lining slipform machine uses a feeding mechanism to transport concrete materials. Specifically, a belt conveyor can be directly used. The belt conveyor has a conveyor belt 5, and the material is transported by the conveyor belt 5. The conveyor belt 5 of the feeding mechanism is arranged along the longitudinal direction. Two belt conveyors can be arranged to improve the feeding efficiency. The two belt conveyors are arranged close to each other and side by side.

[0029] like Figure 3 , Figure 4As shown, a spiral material distribution mechanism is provided in the lining machine to achieve material spreading. The spiral material distribution mechanism includes a silo 6 and a spiral auger 7 arranged in the silo 6, and a motor is also provided to drive the spiral auger 7 to rotate, and the spiral auger 7 achieves material distribution and paving by rotating. Furthermore, the spiral auger 7 is provided with two sections, and the spiral directions of the two sections of the spiral auger 7 are opposite, so that the concrete material delivered to the middle of the silo 6 is transported to both sides.

[0030] like Figure 4 , Figure 5 As shown, the lining slipform machine is provided with a vibrating mechanism to vibrate and compact the concrete layer after paving. The vibrating mechanism is arranged at the rear side of the spiral material distribution mechanism. The vibrating mechanism includes a plurality of high-frequency vibrating rods 8, which are fixedly arranged on the rear inner wall of the silo 6. The high-frequency vibrating rods 8 are arranged at intervals along the transverse length direction of the silo 6, so that the concrete material at each position can be fully vibrated.

[0031] The box beam of the lining slipform machine has a certain extension along the longitudinal direction, such as Figure 1 , Figure 8 As shown, the box beam includes a front box beam 9, a connecting box beam 10 and a rear box beam 11. Among them, both ends of the front box beam 9 are directly connected to the lifting mechanism 2; one end of the connecting box beam 10 is connected to the front box beam 9, and the other end of the connecting box beam 10 is connected to the rear box beam 11. The front box beam 9, the connecting box beam 10 and the rear box beam 11 are an integrally connected structure. The front box beam 9 is mainly used to carry the feeding mechanism, the electric control box, the pump station, etc. The rear box beam is mainly used to carry the spiral material distribution mechanism and the sliding forming mechanism.

[0032] like Figure 1 , Figure 8 As shown, a platform grille 12 can be arranged on the upper end of the front box beam 9, and an electric control box, a pump station, etc. can be arranged on the platform grille. A platform grille 12 can also be arranged on the rear box beam 11.

[0033] When the shaping template 4 is provided, the shaping template 4 is usually installed on the lower side of the rear box beam 11 through the height adjustment cylinder 13. The primary forming template 3 and the shaping template 4 both have a certain length in the transverse direction.

[0034] In actual use, the box girder is a segmented modular structure. The box girder can be installed in segmented configurations, and different sliding mold forming mechanisms below can be replaced to achieve the use of different widths.

[0035] like Fig. 9As shown, when the lining slipform machine is working, the tank truck puts the concrete material on the conveyor belt 4 in the front, and the conveyor belt 4 transports the concrete material to the silo 6. The spiral auger 7 in the silo 6 evenly distributes the material, and the whole machine moves. During the movement, the high-frequency vibrator 8 vibrates the concrete material, and then the slipform part is fed, extruded, and slipformed. After forming, it is finalized again to ensure the construction size accuracy.

[0036] This machine has the characteristics of requiring fewer people, high construction efficiency, high density and high flatness.

[0037] The concrete distribution vibrating lining slipform machine of the present invention can realize the integrated construction of feeding, distribution, vibration and slipform forming through the sequential coordinated construction of the feeding mechanism, the spiral material distribution mechanism, the vibrating mechanism and the slipform forming mechanism. The overall construction efficiency is high, and the high density and flatness of the concrete can be ensured during the working process, and the overall construction quality is good.
