Abstract
Description
Technical Field
[0001] This invention relates to the field of climbing aids, and more particularly to a portable climbing aid. Background Technology
[0002] High-altitude operations are an unavoidable part of forestry production and scientific research, involving various aspects such as the collection of forest tree breeding materials, hybridization and pollination, trait determination, phenological observation, physiological measurement, and pest and disease control. High-altitude operation technology and equipment are an important part of forestry science and technology.
[0003] High-altitude operations in forest areas, especially in the forest areas of southern my country, often face the following difficulties: 1) Complex terrain, characterized by numerous mountains and steep slopes, crisscrossing valleys, and significant topographical variations. Poor road and operational conditions in forest areas make it difficult for large machinery to reach, establish a foothold, and relocate. 2) Tall, densely forested trees, some reaching 20-30 meters in height, and some superior trees exceeding 40 meters, significantly increasing operational difficulty. 3) Rich forest vegetation and complex forest stand structures, particularly in natural and mixed forests where operational space is limited, hindering equipment deployment. 4) Variable forest climates, requiring careful consideration of weather conditions such as strong winds, rainfall, fog, and high temperatures, placing high demands on equipment safety. However, the development of high-altitude forestry equipment in my country has long lagged behind, with insufficient technological innovation. Common tree-climbing equipment such as seed-collecting ladders, tree climbers, and vehicle-mounted lifting platforms have the following shortcomings.
[0004] (1) Seed collection ladder: The working height is low, and it is often impossible to reach the working point. Long ladders are inconvenient to carry and can only help people climb trees, which is dangerous.
[0005] (2) Tree climbing device: It is often difficult to reach the target work point, it can damage the trees, it is labor-intensive, the user needs to be skilled, and the risk factor is high.
[0006] (3) Lifting platform: It is large in size and weight, has high requirements for roads and work sites, is difficult to move, requires professional mechanical operators, and is expensive.
[0007] The aforementioned equipment is insufficient to meet the requirements for high-altitude operations in forest areas, especially for mountainous operations. Summary of the Invention

[0049] like Figure 1 As shown, the present invention provides a portable climbing aid device for locking onto a tree trunk, comprising:
[0050] The drone 100 includes a drone body 110 and a remote controller 120. The drone body 110 is equipped with a controller 111 and a tilt sensor 112 that are electrically connected. The remote controller 120 is electrically connected to the controller 111. The tilt sensor 112 is used to detect the tilt angle of the drone body 110.
[0051] The frame 200, which is disposed at the lower end of the UAV body 110, includes:
[0052] Horseshoe lock 210, which is located at the front end of the frame 200, is used to lock onto the tree trunk;
[0053] Counterweight 220 is located at the rear of the frame 200 and is used to adjust the center of gravity of the frame 200.
[0054] A horizontal adjustment device 300 is disposed on the frame 200. The drone body 110 is connected to the frame 200 through the horizontal adjustment device 300. The horizontal adjustment device 300 is used to adjust the drone body 110 to a horizontal state when the frame 200 is tilted.
[0055] A fixed pulley 400 is located below the front part of the frame 200 and is used to hang the working rope or lead wire.
[0056] The horseshoe lock 210, tilt sensor 112, and leveling device 300 are all electrically connected to the controller 111.
[0057] The method of using this invention is as follows:
[0058] Locate the target tree in the forest where high-altitude operations are required, determine the suitable location on the trunk for mounting the horseshoe lock 210 (i.e., the mounting point), and place the climbing aid device on the open ground around the trunk.
[0059] A thin lead wire is threaded through a fixed pulley. One end of the lead wire is tied to the working rope, and the other end is in the hand of the operator. The drone body 110 is started with the remote control 120. When the drone body 110 takes off, the operator continuously releases the lead wire, and the drone body 110 rises to a high altitude with the lead wire attached.
[0060] When the drone body 110 reaches the attachment point height, the remote controller 120 aligns the opening of the horseshoe lock 210 with the attachment point on the tree trunk. The drone body 110 is then moved so that the horseshoe lock 210 engages with the tree trunk. The drone body 110 is then moved slightly away from the tree trunk so that the inner front wall of the horseshoe lock 210 contacts the tree trunk. The drone body 110 is then stopped. Due to gravity, the frame 200 will experience unilateral force, pulling the rear of the horseshoe lock 210 downwards and lifting the front, thus securing the horseshoe lock 210 tightly to the tree trunk. The drone body 110 and the frame 200 are now in a tilted position. Figure 4 As shown. The purpose of the lead line is to reduce the weight of the drone. When the horseshoe lock 210 is fastened to the tree trunk, the working rope can be pulled up and passed around the fixed pulley back to the ground. One end of the working rope is connected to the winch, and the other end is connected to the lifting device. The working lifting device can be raised by the winch.
[0061] When the drone first takes off, its flight control system has not yet intervened in the drone's balance. If the drone is not level at takeoff, the flight control system will intervene in the flight attitude to correct the balance, which can easily lead to tipping if not handled properly. After the operation is completed, the working rope is pulled away from the fixed pulley 400. When unloading the drone body 110 from the tree trunk, the remote controller 120 issues a leveling command. The controller 111, based on the tilt angle information received from the tilt sensor 112, controls the leveling device 300 to adjust the drone body 110 to a level position. Figure 5 As shown, start the drone body 110, unlock the horseshoe lock 210, let the horseshoe lock 210 leave the tree trunk, and finally control the drone body 110 to land on the ground.
[0062] In summary, the climbing aid device provided by this invention features a horseshoe lock 210 at the front end of the frame 200 and a fixed pulley 400 below. The frame 200 is deployed to a predetermined attachment point via the drone body 110. When attached to the tree trunk, the drone body 110 and the frame 200 are tilted, and the horseshoe lock 210 automatically locks itself onto the trunk due to unilateral force. A leveling device 300 is provided on the frame 200 and the drone body 110. When taking off from the attachment point, the leveling device 300 adjusts the drone body 110 to a horizontal position, reducing the risk of tipping over.
[0063] In the above technical solution, the drone body 110 is adjusted to a horizontal position, such as... Figure 5 As shown, start the drone body 110, unlock the horseshoe lock 210, let the horseshoe lock 210 leave the tree trunk, and after the flight is stable, the frame 200 can also be adjusted to be horizontal through the leveling device 300, and finally control the drone body 110 to land on the ground.
[0064] In some technical solutions, when both the drone body 110 and the frame 200 are in a horizontal state, the center of gravity of the entire assembly of the frame 200, the leveling device 300, and the fixed pulley 400 is on the same vertical line as the center of gravity of the drone body 110, so as to improve the flight stability of the drone body 110. When the drone body 110 flies toward the tree trunk hanging point, the guide line on the fixed pulley 400 is very light and will not affect the flight stability of the drone body 110.
[0065] like Figure 2 As shown, in some technical solutions, the frame 200 includes two parallel guide rails 240, and the horizontal adjustment device 300 includes:
[0066] The slide 301 has two ends that are slidably connected to the guide rail 240;
[0067] The first electric screw 302 is arranged parallel to the guide rail 240, and its front end is fixedly connected to the frame 200, and its middle and rear parts are threadedly connected to the slide 301. The first electric screw 302 is electrically connected to the controller 111.
[0068] Push rod 303, one end of which is hinged to the slide 301;
[0069] The bracket 304 is located on the upper side of the frame 200 and its front end is hinged to the frame 200, and its bottom end is hinged to the other end of the push rod 303. The UAV body 110 is located on the upper side of the bracket 304.
[0070] When the first electric screw 302 receives a command from the controller 111, it rotates and pushes the slide 301 to slide back and forth along the guide rail 240 through the threaded connection. Under the drive of the push rod 303, the bracket 304 will swing relative to the frame 200, thereby adjusting the tilt angle of the drone body 110 relative to the frame 200, so that the drone body 110 is in a horizontal position, reducing the risk of the drone body 110 tipping over when it starts. Although the UAV body 110 is in a horizontal position, the frame 200 is tilted, causing the center of gravity of the frame 200, the leveling device 300, and the fixed pulley 400 to shift forward. Furthermore, the frame 200 includes a second electric screw 230, which is parallel to the guide rail 240. The rear end of the second electric screw 230 is connected to the frame 200, and the front middle part is threadedly connected to the counterweight 220. The second electric screw 230 is electrically connected to the controller 111. The counterweight 220 is slidably mounted on the guide rail 240. When the bracket 304 swings relative to the frame 200, bringing the UAV body 110 to a horizontal position, the controller 111 controls the second electric screw 230 to rotate, causing the counterweight 220 to slide backward. This reduces the overall center of gravity shift of the frame 200, the leveling device 300, and the fixed pulley 400, improving the flight stability of the UAV body 110. During flight, the drone body 110 can control the first electric screw 302 and the second electric screw 230 through the controller 111 to restore the frame 200 to a horizontal position and also return the counterweight 220 to its initial setting position.
[0071] like Figure 2 , Figure 3 As shown, in some technical solutions, the horseshoe lock 210 includes:
[0072] The cross frame 211 is connected at its rear end to the front end of the frame 200;
[0073] Ear plate 212, the rear end of which is connected to the front end of the cross frame 211. An annular locking channel 2121 is provided inside the ear plate (212). The ear plate 212 is C-shaped and its opening is set towards the side of the horseshoe lock 210. Usually, the ear plate opening is designed to face the front end. With this design, when the horseshoe lock 210 is locked on the tree trunk, the locking ring is required to bear the force of the entire device, which is very dangerous. By setting the opening towards the side of the horseshoe lock 210, it can act as an ear plate to bear the force, and the locking ring only plays the role of closing and opening.
[0074] Locking ring 213, which is slidably connected to ear plate 212 via an annular locking channel 2121, and a toothed ring 2131 is provided on the outer side of the locking ring 213;
[0075] A drive unit 214 is mounted on the crossbeam 211 and is drivenly connected to the locking ring 213. The drive unit 214 is electrically connected to the controller 111. The drive unit 214 is a self-locking motor with a gear connected to its output shaft. The gear meshes with the gear ring 2131. The motor can drive the locking ring 213 to slide in the annular locking track 2121 and fix the position of the moving locking ring 213. The controller 111 controls the opening and closing of the horseshoe lock 210 through the drive unit 214 and the locking ring 213.
[0076] In some technical solutions, a rubber protective sleeve is provided on the outer side of the ear plate 212. The outer surface of the rubber protective sleeve is provided with short tooth patterns, which can adhere tightly to the tree trunk when subjected to force, increase friction and prevent the horseshoe lock 210 from sliding down.
[0077] like Figure 2 , Figure 3 As shown, in some technical solutions, the horseshoe lock 210 further includes:
[0078] An electric push rod 215 is disposed on the upper side of the rear end of the ear plate 212, and its center line is parallel to the line connecting the foremost point of the front end and the last point of the rear end of the ear plate 212 and is in the same vertical plane. The electric push rod 215 is electrically connected to the controller 111.
[0079] Top cylinder 216 is sleeved on the front end of the telescopic rod of electric push rod 216 and slidably connected to the telescopic rod of electric push rod 216.
[0080] The elastic element 217 is disposed between the bottom of the top cylinder 216 and the front end face of the telescopic rod of the electric push rod 216. When the horseshoe lock 210 is fitted onto the tree trunk and needs to be locked onto it, the controller 111 controls the telescopic rod of the electric push rod 215 to extend forward, the front end of the top cylinder 216 presses against the tree trunk, and the inner wall of the front end of the ear plate 212 will abut against the tree trunk. There is no need to operate the drone body 110 to move, simplifying the operation. Then, the controller controls the drone body 110 to stop, so that the horseshoe lock 210 is locked onto the tree trunk.
[0081] Some technical solutions also include: a camera 500, which is mounted on the drone body 110, with the lens of the camera 500 facing the horseshoe lock 210, and the camera 500 is electrically connected to the controller 111. The camera 500 transmits the captured images back to the remote control 120, which facilitates the operation of locking and unlocking the horseshoe lock 210 onto the tree trunk.
[0082] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
