Description

Technical Field

[0001] This invention relates to the field of cableway timber collection technology, and in particular to a safety control device for the coordinated operation of cableway timber collection and mechanical timber collection in reserve forests. Background Technology

[0002] A search revealed a cableway timber collection device and its construction method in a Chinese patent publication. The device involves first connecting a rope to a fixed pulley system, a movable pulley system, pulleys, and hooks in sequence. The pulleys are then tied to tree stumps. A log-grabbing excavator is started, and a rope-releasing motor winch is used to move the movable pulley system to the felling point. Hooks are used to catch the felled trees on the slope, and a rope-retracting motor winch is used to drag the trees to the edge of the forest road. A logging machine is then used to remove branches, segment, and stack the collected timber on the forest road. Finally, a log-grabbing excavator is used to load the stacked timber onto trucks.

[0003] However, the cableway timber collection device and its construction method rely solely on the cooperation between the log grabber and the cableway, lacking a collaborative operation mechanism design. This makes it impossible to achieve efficient connection between ground machinery and cableway operations. Furthermore, it lacks safety monitoring and control functions, and cannot monitor and control safety hazards in the timber collection process in real time by setting up monitoring and control components for tension, load, and braking positioning. Based on the shortcomings of existing technology, a safety control device for collaborative operation of cableway timber collection and mechanical timber collection in reserve forests is proposed. Summary of the Invention

[0029] The mechanical timber collection module 3 includes a tractor 301 for dragging and transferring timber in the loading area 7. A second winch 302 is mounted on the tractor 301.

One end of the collection traction cable 303 is detachably connected to a binding cable 304 for binding timber via a connector.

[0030] Both the carrying cable 208 and the circulating traction cable 209 extend to the loading area 7. The circulating traction cable 209 is located at one end of the loading area 7 and is detachably connected to the timber binding cable 304 via a connector.

[0034] Figure 1 The irregular shaded area in the upper right corner is a buffer zone.

[0035] Example 1 In this embodiment, the overall collaborative system's working process and security control implementation process include: Timber Collection (Mechanical Timber Collection Module 3) In the timber loading area 7, the tractor 301 and its second winch 302 are responsible for collecting the scattered timber. After the timber is bundled by the collection traction cable 303 and the timber bundling cable 304, the traction force of the second winch 302 is used to drag the timber laterally to directly below the cableway timber collection trolley 211. During this process, the GPS positioning module 501 installed on the tractor 301 will transmit its position back in real time, so that the central dispatch system can keep track of the timber collection progress.

[0036] Timber loading (cableway and machinery interface) The timber trolley 211 is loaded with collected timber via the hook at the end of the lifting cable 210. The load sensor 504 at the hook monitors the weight in real time to prevent overload operation. At this time, the timber stopper 305 on the carrying cable 208 will fix the position of the timber trolley 211 to prevent it from moving accidentally when loading timber. The operators in the loading area 7 and the unloading area 8 coordinate and command through the communication equipment terminal 307 to ensure loading safety.

[0037] Timber consolidation and transportation (cableway transport and full monitoring) After the material collection trolley 211 is loaded, the material collection stopper 305 is released, the first winch 201 is started, and the material collection trolley 211 is driven along the carrying cable 208 to the unloading area 8 through the circulating traction cable 209.

[0038] Tension monitoring: Wireless tension sensors 401 deployed at the cableway anchor piles 202 and the entrance of the first winch 201 will continuously send tension data of the carrying cable 208 and the traction cable to the PLC control cabinet 403. Once the tension is abnormal, the PLC can control the electric drum 402 to automatically adjust the tension of the carrying cable 208, or notify the braking system to intervene in extreme cases.

[0039] Positioning: The laser rangefinder 502 installed on the intermediate support 203 and the rotary encoder 503 installed on the winding drum 93 shaft of the first winch 201 work together to accurately calculate and monitor the real-time position of the timber trolley 211 on the cableway, and at the same time verify the data with the GPS positioning module 501 of the timber trolley 211 itself.

[0040] Braking protection: The overspeed detection switch 602 monitors the rotation speed of the first winch 201 winding drum 93 in real time. If the material collection trolley 211 is detected to be overspeeding, it will trigger the high-speed shaft hydraulic brake 601. As the last line of defense, the cable clamp 603 installed on the material collection trolley 211 can firmly hold the carrying cable 208 in an emergency such as when the traction cable breaks, to prevent the material collection trolley 211 from going out of control.

[0041] Timber unloading (braking and safety isolation) When the trolley arrives at the unloading area 8, the unloading stopper 306 can effectively prevent it from sliding off the track. After the operator confirms safety through mobile communication equipment, the timber trolley 211 unloads the timber, completing one work cycle.

[0042] Example 2 In this embodiment, the specific operation process in the material collection channel is as follows: Surveying and setting out: First, the terrain needs to be surveyed to determine the cableway route. The longitudinal slope of the cableway should be made as uniform as possible to avoid concave sides. At the same time, measuring tools should be used to mark the accurate positions of the intermediate support 203 and the cableway anchor pile 202 along the selected route.

[0043] Install anchor piles and supports Cableway anchor pile 202: In the terminal areas of high and low terrain, a deep pit is usually required to be dug with a depth of not less than 1.5 meters, a concrete foundation is poured, and anchors are pre-embedded to fix the load-bearing cable 208 and the tension cable. It is essential to ensure that the anchor pile is firm and safe.

[0044] Intermediate support 203: Install the column of intermediate support 203 according to the marked point, and then suspend the turning saddle 206 for line turning or straight saddle on the top of the support through the seat cable 205. Finally, use the saddle cable 204 to firmly fix the support to the ground anchor pile from different directions to ensure its stability.

[0045] Erecting the support cable 208 and the working cable: 207. Laying the thin cable: This is the foundation for laying the main cable. Workers carry lightweight but strong nylon ropes or thin steel wire ropes and walk along the line, climbing over the installed intermediate support 203 to form a guide line that runs through the entire line.

[0046] Traction bearing cable 208: In the unloading area 8, one end of the thin cable 207 is connected to the winding drum 93 of the first winch 201. In the loading area 7, the other end of the thin cable 207 is connected to the main bearing cable 208 with a rigging. The first winch 201 is started, and the heavy bearing cable 208 is gradually dragged to the design position using the thin cable 207 and made to be stably embedded in each saddle.

[0047] Tensioning the load-bearing cable 208: The load-bearing cable 208 is initially tensioned at both ends of the anchor pile by a tensioning device such as an electric drum 402. At this time, the wireless tension sensor 401 starts to work and, together with the PLC control cabinet 403, adjusts the tension of the load-bearing cable 208 to the designed sag. For example, when the span is 300 meters, the sag should be controlled at about 15 meters.

[0048] Laying the circulating traction cable 209 and the lifting cable 210: Similarly, with the help of the thin cable 207, the circulating traction cable 209 and the lifting cable 210 are passed through the corresponding pulleys according to the design path to form a closed loop path.

[0049] Example 3 In this embodiment, the specific operation process in the loading area is as follows: Delineating the area and installing fixing devices: Clear a level work area and clearly mark the loading area 7. Install a timber catcher 305 at one end of the load-bearing cable 208 or at a suitable position in the loading area. This can effectively lock the position of the trolley when bundling timber, ensuring the safety of the loading operation.

[0050] Collaborative timber collection and mounting: Tractor 301 in position: Tractor 301 drives into the loading area and parks on a firm and stable surface. If necessary, use a winch to stabilize the vehicle and prevent it from slipping during operation.

[0051] Mechanical timber collection: The collection traction cable 303 is released from the second winch 302. After the workers use the timber binding cable 304 to bind the timber, they connect it to the collection traction cable 303. The tractor 301 winches the timber and hauls it directly under the timber collection trolley 211.

[0052] Attaching to the cableway: Workers connect the hook of the lifting cable 210 to the binding cable 304 on the timber. After confirming that the connection is secure and that personnel have evacuated to a safe distance, they direct the trolley to lift the timber. The load sensor 504 on the hook will provide real-time feedback on the weight information to prevent overloading.

[0053] In summary, the safety control device for the coordinated operation of cableway and mechanical timber collection in the reserve forest achieves lateral collection of timber on the ground by adding mechanical timber collection module 3, which, together with cableway timber collection module 2, forms a three-dimensional operation chain of ground feeding and aerial transportation. Furthermore, the device enables rapid docking of the binding cable 304 and the circulating traction cable 209 through a detachable connector, thereby constructing a coordinated operation architecture of machinery and cableway, and improving the continuity and automation of the timber collection process. By integrating a multi-dimensional safety monitoring system, a three-in-one monitoring system of tension, positioning, and load is constructed. The tension monitoring module 4 collects real-time tension data of the load-bearing cable 208 and the traction cable, and works with the control electric drum 402 to form a closed-loop tension adjustment. The positioning and status monitoring module 5 uses multi-source data fusion of GPS positioning, laser rangefinder 502, and rotary encoder 503 to achieve precise positioning of the equipment. The load sensor 504 provides real-time feedback on the weight of the timber, effectively preventing the risk of overload. By designing a multi-level braking protection mechanism, a progressive protection system of active early warning, emergency braking, and failure protection is established. The high-speed shaft hydraulic brake 601 is used to achieve rapid braking at the drive end; the overspeed detection switch 602 monitors in real time and triggers a braking signal when the speed exceeds the limit; the cable clamp 603 is equipped to lock the load-bearing cable 208 under extreme working conditions, and together with the material collection stop 305 and the unloading stop 306, the position of the trolley is effectively locked to achieve emergency braking.

[0054] The above specific embodiments are merely optional embodiments of the present invention.
