Description

Technical Field

[0001] The invention relates to a ropeway material collection and transportation method, in particular to a bamboo material collection and transportation method and system. Background Art

[0002] Bamboo is a green, environmentally friendly, renewable natural resource that can be harvested after felling. It usually takes 3-5 years to mature and can be harvested every year. However, since bamboo forests are usually natural forests, a large part of them grow on steep slopes. Due to the restrictions of slopes and ditches in the forest area, the construction of forest roads is lagging behind, and general vehicles cannot pass through. It is difficult and costly to harvest and transport bamboo from the mountains. For a long time, bamboo forests have mostly been managed through simple manual management and maintenance, mostly manual work. After manual felling, the bundled bamboo is transported to the foot of the mountain through high-intensity human or animal power. This traditional production method is backward, with high labor intensity, low mining efficiency and high transportation costs. In order to reduce labor intensity, some people use the method of "sliding slope" or "pre-buried pipeline" to slide bamboo from the mountain to the foot of the mountain, that is, using the gravity of bamboo to slide down the slope or pipeline from the top of the mountain to the bottom of the mountain, but "sliding slope" can easily cause bamboo damage and cracking, and pipelines need to be temporarily laid, which is time-consuming, labor-intensive and inefficient. There are also methods that use steel wire ropes as transport ropeways, and the coordination of retractable wires and pulley mechanisms to achieve the purpose of rapid bamboo transportation, effectively reducing the labor intensity of bamboo workers. However, due to the large number of branches and twigs above the bamboo forest, it is difficult to arrange the transport ropeway in the early stage, and the service life and safety requirements of the steel wire rope are also high, and the preset cost of the ropeway is too high. Summary of the invention

[0003] The purpose of the present invention is to provide a bamboo ropeway material collection and transportation method, which has simple process and convenient implementation, can reduce the labor intensity of bamboo material collection and improve the material collection efficiency.

[0051] The end of the steel wire rope 441 of the electric hoist 44 on the transport sports car 4 of the present invention can be connected to a clamp 6 convenient for dragging bamboo. As Figures 7 - 9 shown in the figure, it is Embodiment 1 of the clamp of the present invention. The clamp includes an upper clamping plate 61 and a lower clamping plate 62 which are oppositely arranged. Concave portions 63 with an arc-shaped cross-section are provided on the bottom surface of the upper clamping plate 61 and the top surface of the lower clamping plate 62. Both sides of the upper clamping plate 61 and the lower clamping plate 62 are connected by a plurality of parallel connecting rods 64. Both ends of each connecting rod 64 are respectively hinged to the sides of the upper clamping plate 61 and the lower clamping plate 62. On both sides of the lower clamping plate 62, side plates 65 extend upward.
