Abstract
Description
Technical Field
[0001] The utility model relates to a trolley, in particular to a main hinge trolley for asphalt paving on a slope. Background Art
[0002] Slope asphalt concrete paving involves laying asphalt concrete on a steeply sloped road surface. This is a highly specialized type of asphalt concrete paving operation, commonly used in projects such as racetracks, landfills, and pumped-storage power station reservoir anti-seepage. Compared to paving on flat surfaces, this construction method presents challenges, as it requires consideration of the effects of gravity on the asphalt mixture and ensuring paving uniformity and surface smoothness. Furthermore, given the temperature requirements of asphalt concrete construction, slope paving requires addressing issues such as slope feeding and continuous paving, as opposed to flat surface paving.
[0003] At present, the structure of slope asphalt concrete paving mainly adopts bridge-type paver, which involves equipment in conjunction with highway paver for construction. It has a complex structure, many control factors, and is relatively cumbersome to operate. The coherence and continuity between each step are weak, which affects the efficiency of continuous paving.

[0016] Example:
[0017] like Figure 1-Figure 2As shown, the main hinge trolley for slope asphalt paving includes a frame 1, on which is mounted an inclined conveyor frame 2, on which a feeder trolley 31 and a paving trolley 41 are placed. A drive sheave 21 is provided at the upper end of the conveyor frame 2. The frame 1 is also equipped with a first hoist 3 and a second hoist 4. The drums of both the first hoist 3 and the second hoist 4 are wound with a traction rope 5 that passes around the drive sheave 21. The traction rope 5 of the first hoist 3 is connected to the feeder trolley 31 and is used to pull the feeder trolley 31 along the conveyor frame 2. The traction rope 5 of the second hoist 4 is connected to the paving trolley 41 and is used to pull the paving trolley 41 along the conveyor frame 2. The first hoist 3 has a speed of 0 to 40 m / min and a rated pulling force of 80 kN. The second hoist 4 has a speed of 0 to 10 m / min and a rated pulling force of 2 x 125 kN.
[0018] The bottom of the frame 1 is provided with a walking mechanism 11. The walking mechanism 11 adopts a crawler chassis. The crawler running motor of the crawler chassis adopts a YZPEJ225M-4-45KW vertical normally closed motor with a brake.
[0019] The lower end of the conveyor frame 2 is movably connected to a support leg 22, and a telescopic mechanism 23 is provided at the bottom of the conveyor frame 2 to drive the support leg 22 to extend and retract. The support leg 22 can be connected to the conveyor frame 2 in a rotating or sliding manner, and the telescopic mechanism 23 can be a hydraulic cylinder. During construction, the hydraulic cylinder drives the support leg 22 to extend from the lower end of the conveyor frame 2 and connect to the ground, facilitating the transfer of the feeding vehicle 31 and the paving vehicle 41 to the ground. When not in operation, the hydraulic cylinder drives the support leg 22 to retract into the conveyor frame 2, reducing occupied space and facilitating the movement of the trolley driven by the walking mechanism 11.
[0020] The hopper 6 is slidably connected to the frame 1 via a lifting frame 64. Specifically, the lifting frame 64 is slidably connected to the frame 1 via slide rails, and the hopper 6 is mounted on the lifting frame 64. A third hoist 61 is installed at the top of the frame 1. A hoisting rope 63 is wound around the drum of the third hoist 61, which is used to raise the lifting frame 64 along the height of the frame 1. The drums of the third hoist 61 are connected symmetrically via a rotating shaft 62. The hoisting ropes 63 of the third hoist 61 are connected to either side of the lifting frame 64, ensuring stability during the lifting of the hopper 6. The third hoist 61 has a speed of 0 to 20 m / min and a rated pulling force of 2 x 32 kN.
[0021] The working principle of the present invention is as follows: a feeder trolley 31 and a paving trolley 41 are placed on the conveyor frame 2. During construction, the hydraulic cylinder is activated to drive the outriggers 22 out of the conveyor frame 2, causing the outriggers 22 to contact the ground. The second winch 4 is activated to place the paving trolley 41 on the conveyor frame 2 along the conveyor frame 2 and the outriggers 22 to the bottom of the embankment. The asphalt transport vehicle unloads asphalt concrete and other materials into the hopper 6. The third winch 61 is then activated to lift the hopper 6 filled with materials to the feeder trolley 31 and pour the materials in the hopper 6 into the bucket of the feeder trolley 31. The first winch 3 is then activated to place the feeder trolley 31 along the conveyor frame 2 in front of the paving trolley 41. The materials in the bucket of the feeder trolley 31 are unloaded into the bucket of the paving trolley 41 and paving begins. Finally, the first winch 3 is used to retract the feeder trolley 31 to its original position. This feeding cycle continues until construction is completed.
