Description

Technical Field

[0001] The invention belongs to the technical field of timber collection in forest areas, and in particular relates to a double-capstan double-rope circulation reverse slope timber collection method for steep mountainous areas. Background Art

[0002] With the continuous advancement of forestry mechanization, more and more forestry machinery has begun to enter forest areas to participate in forestry production activities, which is of great significance for reducing the labor intensity of forestry workers, improving forestry production efficiency, and promoting the sustainable development of forestry production. Timber harvesting and transportation operations in steep mountain forest areas are one of the most labor-intensive and difficult production links in forestry production. In order to reduce the labor intensity of reverse-slope logging in felling areas and improve logging efficiency, some forest areas have widely adopted a cable logging machine with a tractor equipped with a winch for reverse-slope logging operations (such as Figure 1 As shown in the figure, it greatly improves the efficiency of wood back-slope collection and reduces the labor intensity and production cost of workers to a certain extent. However, when this collection method is used, a hook is connected to the end of the winch traction rope. Workers pull the hook and traction rope to the bottom of the hillside to bundle the felled logs and then start the winch to pull the wood onto the forest road. The problem with this device is that after unloading the wood, the hook and traction rope cannot automatically return to the bottom of the hillside for wood bundling and collection operations. The wood bundlers at the bottom of the mountain must return to the mountain road to pull the hook and traction rope back to the bottom of the hillside before continuing the wood bundling operation. In this way, the workers must go back and forth along the hillside twice to follow the hook to complete a collection operation, which has high labor intensity and low work efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a double winch double rope circulation reverse slope logging method for steep mountain slopes in order to solve the problems of low efficiency of winch logging and high labor intensity of workers in the prior art.

[0004] In order to achieve the above object, the technical solution of the present invention is as follows:

[0005] A method for reverse slope logging with double winches and double ropes in a steep mountainous area comprises the following steps:

[0006] Step 1: Drive the double-capstan tractor to the forest road above the felling area, select the anchoring wood I in front of the double-capstan tractor to fix the double-capstan tractor, and then anchor the double-capstan tractor with a tension rope;

[0007] Step 2: Two winches are installed at the rear of the double-winch log collection tractor, and the corresponding drums of the two winches are respectively wound around the fixed end of the traction rope I and the fixed end of the traction rope II, and the two drums can independently control forward and reverse rotation and idling;

[0008] Step 3: Select anchor wood II at the lower rear of the double-capstan log collection tractor as the first fulcrum of the cable, and install two guide pulleys I side by side on anchor wood II; select anchor wood III at the upper rear of the double-capstan log collection tractor as the second fulcrum of the cable, and install two guide pulleys II side by side on anchor wood III; select anchor wood IV at the log collection point at the bottom of the mountain as the third fulcrum of the cable, and install a guide pulley III on anchor wood IV;

[0009] Step 4: The ends of the traction rope I and the traction rope II are passed around two guide pulleys I and two guide pulleys II in sequence; one end of the return rope is connected to the end of the traction rope I through the iron ring I, and the other end of the return rope is passed around the guide pulley III and connected to the end of the traction rope II through the iron ring II, so that the traction rope I, the traction rope II and the return rope form a closed cable, and the two ends of the return rope move up and down on the forest road and the collection point respectively under the recovery action of the traction rope I or the traction rope II; the iron ring I is provided with a wood binding rope I, and the iron ring II is provided with a wood binding rope II;

[0010] Step 5: Call the winch operator through the intercom to start the winch corresponding to the traction rope I to retract the traction rope I. At the same time, the other winch is set to neutral so that the traction rope II is in a free state. At this time, the bundle rope I is pulled to the forest road on the slope by the traction rope I. The return rope uses the traction force of the traction rope I to pull the traction rope II and its bundle rope II down the slope to the collection point;

[0011] Step 6: Tie the end of the felled log with the wood rope II, notify the winch operator through the intercom, start the winch corresponding to the traction rope II to recycle the traction rope II, and at the same time, put the other winch in neutral to make the wood run up the slope. At this time, the return rope uses the traction force of the traction rope II to pull the traction rope I and the wood rope I down the hillside. When the wood rope II and the wood reach the road surface of the forest road, the wood rope I also arrives at the wood collection point at the bottom of the mountain at the same time, and the wood rope I is also tied with the wood at the same time. Call the winch operator through the intercom to start the winch corresponding to the traction rope I to recycle the traction rope I, so that the wood rope I and the wood run up the slope. At this time, the return rope uses the traction force of the traction rope I to pull the traction rope II and its wood rope II down the slope. This reciprocating cycle is carried out for wood collection until the wood near the anchor wood IV is collected.

[0012] Step 7: After collecting the wood near anchor wood IV, move the guide pulley III to the bottom of other uncollected anchor woods, and repeat the above operation until all the wood in the entire felling area is collected on the road surface.

[0013] The present invention further describes that the anchor wood I, anchor wood II, anchor wood III and anchor wood IV are living standing trees or stumps respectively.

[0014] The present invention further describes that the wood-binding rope I and the wood-binding rope II are connected to the iron ring I and the iron ring II respectively through hooks.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present invention adopts two drums and two traction ropes to collect materials alternately up and down, and adopts a return rope and a guide pulley to close the two traction ropes at the same time, which not only doubles the material collection efficiency, but also when one of the traction ropes pulls the wood up the mountain, the empty bundle of wood rope on the end of the other traction rope is automatically sent back to the bottom of the hillside through the return rope, without the need for manpower to return the empty bundle of wood rope, reducing the labor intensity of workers, and effectively solving the problem that the current winch machine has low material collection efficiency and high labor intensity of workers.
