Description

Technical Field

[0001] This invention relates to the field of timber handling, specifically to an auxiliary device for improving timber handling efficiency. Background Technology

[0002] Timber handling is the process of moving timber, including logs, lumber, and square timber, from one location to another using manpower, machinery, or auxiliary equipment. This process is widely used in forestry production, such as transporting logs from forest land after logging, in timber processing plants (e.g., transporting raw materials to processing equipment and finished products to storage areas), and in construction (e.g., transporting timber to construction sites and allocating it to its intended use). Its core purpose is to achieve the spatial transfer of timber within the supply chain or production process, ensuring the continuity of production, construction, and other activities.

[0003] Currently, the handling of cylindrical timber relies mainly on manual dragging or simple mechanical hoisting. Because cylindrical timber has a smooth surface and is easy to roll, it requires the coordinated efforts of many people, which is not only extremely labor-intensive and inefficient, but also poses a risk of squeezing and crushing due to the easy rolling of cylindrical timber. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides an auxiliary device to improve the efficiency of timber handling, which solves the problems of low efficiency and easy crushing and damage when handling cylindrical timber.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: an auxiliary device for improving timber handling efficiency, comprising a mobile device, wherein the mobile device is equipped with a swaying wheel and a spooling wheel for rotation, the swaying wheel has a gradient profile, the two mobile devices are respectively located on both sides of the log, and the two spooling wheels share a single strap.

[0006] When the roll retracts the bandage, it is used to limit the distance between the two lifting wheels. When either lifting wheel rotates, the outer side of its gradient profile lifts the log and causes the log to leave the ground. The bandage binds the log, causing the log to be wedged between the bandage and the two lifting wheels. The bandage and the two lifting wheels work together to stabilize the log.

[0007] Preferably, the radius of the rocker wheel gradually increases along its transition direction.

[0008] Preferably, the radius of the rocker wheel is smaller at one end closer to the log than at the other end.

[0009] Preferably, the outer peripheral surface of the rocker wheel is fixed with a number of barbs distributed at equal intervals, and the rocker wheel and the number of barbs are integrally formed.

[0010] Preferably, the barb is tilted.

[0011] Preferably, one end of the barb is rounded.

[0012] Preferably, the number of mobile devices is two groups, located at both ends of the log, with two mobile devices in each group, and they are arranged symmetrically.

[0013] Preferably, the mobile device is fixedly mounted on a bracket, and the rocker wheel is rotatably mounted inside the bracket.

[0014] Preferably, the mobile device is fixedly mounted with a housing, and the roller is rotatably mounted in the housing.

[0015] Preferably, the bandage includes a hollow band body, reinforcing ribs, and several wires. The reinforcing ribs and several wires are all fixed inside the hollow band body. The reinforcing ribs and wires are arranged perpendicularly and fixed together.

[0016] Compared with existing technologies, this invention has the following advantages: It eliminates manual dragging, using a gradually contoured lifting wheel and coordinated restraint with straps to avoid the risks of squeezing and crushing caused by log rolling, ensuring personnel safety and wood quality. Throughout the handling process, the gradually contoured lifting wheel and barbs continuously adhere to the log, offsetting vibrations and bumps. The dynamic micro-adjustment of the strap tension by the rollers, along with the relative positions of the support frame, shell, and other stable components, ensures stable log clamping from multiple dimensions, reducing the risk of slippage and detachment, ensuring a smooth handling process, and lowering the probability of equipment failure and wood loss. In the two sets of mobile equipment, one set can be used as the active set, and the other as the passive set. Using straps and logs, one power input drives both sets of equipment in tandem, eliminating the need for additional power for the passive set. Remote control makes operation more convenient, and the direction and speed of movement can be flexibly adjusted remotely, adapting to complex site operations and improving handling flexibility.

[0027] like Figures 1-9 As shown, an auxiliary device for improving timber handling efficiency includes a mobile device 1. The mobile device 1 is equipped with a rotating pry wheel 2 and a roller 3. The pry wheel 2 has a gradually changing profile; its radius gradually increases along the changing direction. During rotation, the radius change generates a lever effect, lifting the log with less force and reducing energy consumption. The gradually changing profile ensures a smooth transition at the contact point, preventing excessive instantaneous force that could damage the log or overload the equipment, improving operational stability. It is adaptable to cylindrical logs of different diameters, enhancing the device's versatility. The radius of the pry wheel 2 is smaller at one end closer to the log than at the other, ensuring good initial contact with the log. As it rotates, the larger radius gradually applies force, preventing slippage due to an initially small contact area. This makes it easier for the pry wheel 2 to embed under the log, especially suitable for uneven ground, improving the device's adaptability to complex terrain. Several equally spaced barbs 5 are fixed to the outer circumference of the pry wheel 2, and the pry wheel 2 and the barbs 5 are integrally formed. The barbs 5 on the outer circumference of the lifting wheel 2 are integrally formed with the body, enhancing structural strength and preventing the barbs 5 from falling off. The evenly distributed barbs 5 increase the friction with the wood, preventing the log from sliding relative to the lifting wheel 2 during lifting or handling, solving the problem of smooth and easy rolling of cylindrical wood surfaces. The barbs 5 rotate synchronously with the lifting wheel 2, further improving the stability of the lifting process and reducing secondary adjustment operations. The barbs 5 are set at an angle, with one end of the barbs 5 having a rounded corner. Two mobile devices 1 are located on both sides of the log, and two rollers 3 share a single strap 4. The mobile devices 1 carry the lifting wheel 2 and rollers 3, and the strap 4 connects the two devices, forming an integrated structure for lifting, restraining, and linkage. The rotation of the lifting wheel 2 lifts the log, and the rollers 3 retract the strap 4 to limit the spacing and stabilize the log. Handling can be completed without manual dragging, greatly reducing labor intensity. The symmetrical distribution of the devices on both sides adapts to the shape of cylindrical wood, solving the problems of easy rolling and unstable clamping in traditional hoisting, improving the safety and efficiency of handling.

[0028] When the reel 3 winds up the bandage 4, it limits the distance between the two lifting wheels 2. When either lifting wheel 2 rotates, the outer side of its gradient contour lifts the log, causing it to detach from the ground. The bandage 4 binds the log, causing it to be wedged between the bandage 4 and the two lifting wheels 2. The bandage 4 and the two lifting wheels 2 work together to stabilize the log. The bandage 4 includes a hollow band body 401, reinforcing ribs 402, and several wires 403. The reinforcing ribs 402 and several wires 403 are all fixed inside the hollow band body 401. The reinforcing ribs 402 and the wires 403 are set perpendicularly and fixed together. The reinforcing ribs 402 and the wires 403 inside the bandage 4 are fixed perpendicularly to each other, forming a grid-like reinforcement structure that retains the hollow bandage 4. The flexibility of the core strap 401 conforms to the curved surface of the wood, while the rigid frame enhances the tensile strength, solving the problem of easy breakage or deformation of traditional slings. The vertically arranged reinforcing ribs 402 and iron wires 403 distribute the force, avoid local overload, extend the service life of the bandage 4, and ensure flatness when winding, reducing the instability caused by wrinkles in the bandage 4. There are two sets of mobile devices 1, located at both ends of the log. Each set has two mobile devices 1, which are symmetrically arranged. A bracket 6 is fixedly installed on the mobile device 1, and the lifting wheel 2 is rotatably installed in the bracket 6. A housing 7 is fixedly installed on the mobile device 1, and the winding wheel 3 is rotatably installed in the housing 7.

[0029] In use, two sets of mobile devices 1 are placed at both ends of the log, with two mobile devices 1 in each set symmetrically distributed on both sides of the log. The lifting wheels 2 and the winding wheels 3 on the mobile devices 1 are in a ready-to-work state. The mobile devices 1 are modular devices that integrate power, movement, support and transmission functions. They are the mobile carriers of the entire timber handling auxiliary device. The straps 4 are initially set on the winding wheels 3. The lifting wheels 2 have a gradually increasing radius from the end near the log to the other end, and can contact the log at different radius points when rotating. It should be noted that when the device is working, the mobile devices 1 serve as the power bearing base. The power unit, such as a motor, can be integrated into the mobile devices 1 and is a conventional power output torque. When the handling process is started, the power is transmitted through the transmission mechanism of the mobile devices 1, such as gear sets and belt drives, for torque transmission and speed adjustment, to the lifting wheels 2 and the winding wheels 3, driving them to rotate synchronously or according to preset logic. It can also be operated manually, such as by connecting the crank handle to the shaft of the winding wheels 3, which is suitable for simple scenarios. External force is applied to make the winding wheels 3 and the lifting wheels 2 rotate to meet the power requirements of different working environments.

[0030] Next, during the log lifting process, as the lifting wheel 2 rotates, due to the characteristics of the gradient contour, the end with the smaller radius contacts the log first. As it rotates, the part with the larger radius gradually acts on the log, using the outer side of the gradient contour to lift the log and remove it from the ground. This process is aided by the inclined barb 5 integrally formed on the outer circumference of the lifting wheel 2. One end of the barb 5 is rounded to avoid damaging the wood, enhance the friction between it and the log, and assist in a more stable and efficient lifting action. During the process of binding and stabilizing the log, the rolling wheel 3 simultaneously applies pressure to the bandage 4. During the winding operation, the distance between the two lifting wheels 2 is limited, allowing the bandage 4 to gradually conform to the log. In conjunction with the two lifting wheels 2 that have already lifted the log, the log is inserted into the space formed by the bandage 4 and the two lifting wheels 2. The inside of the bandage 4 is composed of reinforcing ribs 402 and vertically fixed iron wires 403, which are placed inside the hollow bandage body 401 to ensure strength and effectively restrain the log. At the same time, the lifting wheels 2 and the bandage 4 work together to restrict the displacement of the log from multiple directions, achieving stable clamping. The log can then be moved by the mobile equipment 1 to complete the transport.

[0031] like Figure 6 and Figure 7 As shown, when the roller 3 rotates, it winds up the bandage 4 through the winding relationship between its own axle and the bandage 4. During the winding process, the length of the bandage 4 shortens. Since the two rollers 3 share a single bandage 4, they pull on the two side moving devices 1, limiting the distance between the two rocker wheels 2, causing the two rocker wheels 2 to gradually fit against the surface of the log. After the rocker wheels 2 lift the log, the roller 3 continues to wind up the bandage 4, causing the log to be clamped into the clamping space formed by the bandage 4 and the two rocker wheels 2. At this time, the reinforcing ribs 402 inside the bandage 4 and the vertically fixed iron wires 403 ensure the structural strength, and together with the rocker wheels 2, restrict the displacement of the log from multiple directions, achieving stable binding of the log.

[0032] It should be noted that two sets of mobile devices 1 are symmetrically arranged at both ends of the cylindrical log, with each set containing two mobile devices 1. Before operation, using the gradually changing contour of the pry bar 2, the log is clamped between the bandage 4 and the two pry bars 2 by rotating the pry bar 2 and utilizing the leverage effect of the changing radius, along with the outer barbs 5. At this time, both sets of mobile devices 1 are in a ready-to-move state. One set of mobile devices 1 is designated as the active set. Its power unit, such as a motor, is activated by a remote control command. The active set of mobile devices 1 performs forward, backward, and turning movements according to the remote control signal, and begins to move using the bottom wheels. Since the bandage 4 connects the rollers 3 of the two sets of mobile devices 1, and the log has been stably bound between the devices, when the active set moves, it will generate a traction force on the driven set of mobile devices 1 through the bandage 4. The driven set, due to its interaction with the active set, will exert a traction force on the driven set of mobile devices 1. The group is mechanically connected to the log by the bandage 4. Without additional power, it is dragged and moved synchronously with the log under the pulling force of the active group. It realizes one power input and two groups of coordinated handling, which simplifies the power configuration and improves the convenience of operation. During the handling, the roller 3 of the active group mobile device 1 can finely adjust the winding tension of the bandage 4 according to the moving posture. This is achieved by the power unit and the transmission structure to maintain the stability of the log binding. The gradual contour and barb 5 of the rocker wheel 2 continuously fit the log to offset the vibration and bumps during the movement and prevent the log from slipping. The driven group mobile device 1 relies on its own structure to adapt to the moving rhythm of the active group. During the following process, the bracket 6, the shell 7, the wire 403 and the reinforcing rib 402 ensure the relative position stability of the rocker wheel 2 and the roller 3, ensuring that the whole set of devices can efficiently and safely complete the handling of cylindrical wood under remote control.
