Description

Technical Field

[0001] This utility model relates to the field of wireless remote control grab technology, specifically a 2x wireless remote control narrow grab for timber. Background Technology

[0002] The wireless remote-controlled timber grab is a hydraulic grabbing device compatible with gantry cranes, loaders, and other lifting machinery. Specifically designed for timber loading and unloading operations, it achieves remote operation via a wireless remote control system with a range of 50-100 meters, eliminating the need for personnel to be close to the work area. It eliminates the collision and fall hazards associated with traditional manual hooking operations, and allows for fine-tuning of the grab's opening angle and force via a handle, precisely adapting to different types of timber such as logs, planks, and square timber, reducing material loss during grabbing. Structurally, the grab jaws are constructed from high-strength manganese steel, making them wear-resistant and deformation-resistant. Combined with a stable hydraulic drive system, it can grab weights ranging from 1 to 30 tons in a single operation, flexibly matching various lifting equipment. Currently, this equipment is widely used in port timber berths, forestry collection points, and engineered wood factories, typically replacing the workload of 2-3 workers, increasing loading and unloading efficiency by over 40%, while significantly reducing labor costs and the accident rate.

[0003] However, existing wireless remote-controlled timber grabs do not adopt a narrow grab design, which cannot prevent collisions with small boat hulls and cannot significantly improve response speed and loading and unloading efficiency. At the same time, existing wireless remote-controlled timber grabs do not adopt a double-ratio wire rope transmission structure, which cannot reduce the amount of rope pulling, making them less practical. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a 2x wireless remote-controlled narrow grab bucket for timber, thereby resolving the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 2x wireless remote-controlled narrow grab for timber, comprising an upper support beam, a rope guide device at the top of the upper support beam, a balancing frame above the upper support beam, small shackles at both ends of the lower part of the balancing frame, a large shackle at the top of the balancing frame, a long ring fitted inside the large shackle, the long ring being connected to a gantry crane hook, two sliding seats between the upper and lower support beams, each sliding seat having a pulley rotatably mounted on its opposite side via bearings, and one side of the lower support beam being bolted... An external oil tank is installed, and a hydraulic system component is located inside the lower support beam on the outside of the oil tank. A remote control system component is also externally installed on the side of the lower support beam away from the oil tank via bolts. Two sets of meshing bucket teeth are provided on the inner side of the lower support beam. A support rod is provided between the bucket teeth and the upper support beam. The support rod is connected to the bucket teeth and the upper support beam via pins. A fixed wedge sleeve is also provided at the top of the upper support beam. An inclined wedge is connected to the inner wedge sleeve of the fixed wedge sleeve. A wire rope is provided between the inclined wedge and the small shackle. A hydraulic cylinder is provided between the lower support beam and the sliding seat.

[0006] Preferably, the hydraulic system component is connected to the cylinder and the oil tank via oil pipes, and the hydraulic system component is electrically connected to the remote control system component. One end of the oil pipe passes through the panel of the lower bearing beam and is connected to the upper cavity of the cylinder, while the other end is connected to the lower cavity of the cylinder and extends into the oil tank.

[0007] Through the above technical solution, the hydraulic system components can stably deliver or recover hydraulic oil to the cylinder through oil pipes, ensuring that the cylinder can extend and retract smoothly. At the same time, with the help of the electrical connection with the remote control system components, the solenoid valve in the hydraulic system can be remotely controlled by the remote controller to switch, thereby controlling the movement of the cylinder, and finally realizing the remote control opening and closing of the grab bucket. This not only avoids the cumbersome manual operation of traditional rope grab buckets, but also ensures the reliability of hydraulic transmission, meeting the needs of efficient loading and unloading of timber at port terminals.

[0008] Preferably, the wire rope passes through the guide rope device and the upper support beam and is sleeved on the outside of the pulley. The wire rope is folded back by the pulley and fixedly connected to the inclined wedge inside the fixed wedge sleeve.

[0009] Through the above technical solutions, the guide rope device can limit the direction of the wire rope, preventing it from deviating or getting stuck. After the wire rope is folded back by the pulley, it forms a double-strength structure, effectively reducing the amount of rope pulling. This is suitable for scenarios where the lifting height of the gantry crane is limited. At the same time, with the cooperation of the fixed wedge sleeve and the inclined wedge, the wire rope can be firmly fixed to the upper support beam. The wedge sleeve fixing method facilitates the disassembly and installation of the wire rope in the later stage, reducing maintenance costs and meeting the requirements for long-term stable operation of the equipment.

[0010] Preferably, the guide rope device, sliding seat, pulley, fixed wedge sleeve, inclined wedge, small shackle and wire rope are all provided in two identical units. The fixed wedge sleeve and inclined wedge are symmetrically distributed at the top of the upper bearing beam, and the guide rope device is also symmetrically distributed at the top of the upper bearing beam. The fixed wedge sleeve and inclined wedge and the guide rope device form a cross shape.

[0011] The above technical solution, with its symmetrical arrangement of two sets of components, ensures that the grab bucket is subjected to uniform force on both sides when grabbing timber, avoiding the problem of the grab bucket tilting and timber falling due to excessive force on one side. The "+" shaped distribution optimizes the component layout at the top of the upper support beam, preventing interference between components and ensuring that the functions of wire rope transmission, guide rope limiting, and rope fixing do not affect each other, further improving the stability and reliability of equipment operation and making it suitable for high-intensity loading and unloading operations at port terminals.

[0012] Preferably, there are two identical hydraulic cylinders, which are symmetrically distributed on both sides of the upper part of the lower support beam. The lower end of the hydraulic cylinder is fixed to the lower support beam by bolts, and the upper end of the hydraulic cylinder is fixed to the sliding seat by nuts. The sliding seat can slide along the vertical direction of the upper support beam.

[0013] Through the above technical solution, the symmetrical distribution of the two hydraulic cylinders can provide a uniform locking force for the connection between the lower support beam and the sliding seat, ensuring structural stability when grabbing timber and avoiding deformation of the grab bucket caused by the force of a single hydraulic cylinder. The design of the sliding seat sliding vertically along the upper support beam, combined with the extension and retraction of the hydraulic cylinder, can accurately control the lifting and lowering amplitude of the lower support beam, thereby achieving stable adjustment of the grab bucket opening. This not only ensures the amount of timber grabbed, but also prevents the grab bucket from hitting the ship.

[0014] Preferably, the remote control system component includes a remote controller and a receiver. The receiver is electrically connected to the solenoid valve of the hydraulic system component. The remote controller communicates with the receiver via wireless signals. The bucket teeth adopt a narrow grab structure, and the width of the wide grab is 1.2m to 1.8m, and the opening is 3m to 4m.

[0015] Through the above technical solution, the wireless communication design between the remote controller and the receiver allows operators to control the opening and closing of the grab bucket without close contact, reducing operational safety risks. The operation response is also rapid, improving loading and unloading efficiency. The narrow structure of the bucket teeth, with a width of 1.2m to 1.8m, can adapt to scenarios where the loading vessel is small, avoiding collisions between the grab bucket and the hull. Meanwhile, the opening of 3m to 4m can ensure the amount of timber grabbed in a single operation, achieving a balance between collision prevention and high efficiency, perfectly meeting the customer's needs for loading and unloading timber on small boats.

[0016] Compared with the prior art, this utility model provides a 2x wireless remote-controlled narrow grab for timber, which has the following advantages: 1. This double-rate wireless remote-controlled narrow grab bucket for timber is highly adaptable to specific timber loading and unloading scenarios such as small boats. Its double-rate wire rope transmission structure reduces the amount of rope pulling and is suitable for situations where the lifting height of the gantry crane is limited. The symmetrical distribution design of the dual hydraulic cylinders can accurately control the grab bucket opening of 3m to 4m. Combined with the narrow grab bucket structure with a width of 1.2m to 1.8m, it avoids collisions with small boat hulls and ensures the amount of timber grabbed in a single operation. At the same time, the wireless remote control system replaces traditional manual operation, greatly improving response speed and loading and unloading efficiency.

[0017] 2. This double-rate wireless remote-controlled narrow grab bucket for timber features symmetrically distributed components such as double-set rope guides and pulleys in a cross-shaped layout, ensuring even force distribution on both sides of the grab bucket and preventing tilting or timber falling. The hydraulic system provides stable pressure to the cylinders, ensuring reliable opening and closing of the grab bucket. The combination of the fixed wedge sleeve and the inclined wedge not only firmly secures the wire rope but also facilitates later maintenance and disassembly, meeting the needs of long-term high-intensity operations.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: like Figure 1-4As shown, this utility model provides a 2x wireless remote-controlled narrow grab bucket for timber, including an upper support beam 3. A rope guide device 4 is installed at the top of the upper support beam 3. A balance frame 1 is installed above the upper support beam 3. Small shackles 18 are installed at both ends of the lower part of the balance frame 1. A large shackle 12 is installed at the upper part of the top of the balance frame 1. A long ring 13 is fitted inside the large shackle 12 and is connected to the hook of the gantry crane. Two sliding seats 6 are installed between the upper support beam 3 and the lower support beam 7. Pulleys 17 are rotatably mounted on opposite sides of the sliding seats 6 via bearings. An oil tank 16 is externally mounted on one side of the lower support beam 7 via bolts. A hydraulic system component 10 is installed on the outside of the box 16 inside the lower support beam 7. A remote control system component 11 is also installed on the side of the lower support beam 7 away from the oil tank 16 by bolts. Two sets of meshing bucket teeth 8 are provided on the inside of the lower support beam 7. A support rod 5 is provided between the bucket teeth 8 and the upper support beam 3. The support rod 5 is connected to the bucket teeth 8 and the upper support beam 3 by pins. A fixed wedge sleeve 14 is also provided at the top of the upper support beam 3. An inclined wedge 15 is connected to the wedge sleeve inside the fixed wedge sleeve 14. A wire rope 2 is provided between the inclined wedge 15 and the small shackle 18. A hydraulic cylinder 9 is provided between the lower support beam 7 and the sliding seat 6.

[0022] Example 2: like Figure 1-4 As shown, as an improvement to the previous embodiment, this is done to meet the need for efficient loading and unloading of timber.

[0023] Specifically, the hydraulic system component 10 is connected to the cylinder 9 and the oil tank 16 via oil pipes. The hydraulic system component 10 is electrically connected to the remote control system component 11. One end of the oil pipe passes through the panel of the lower support beam 7 and connects to the upper cavity of the cylinder 9, while the other end connects to the lower cavity of the cylinder 9 and extends into the oil tank 16. The advantage is that the hydraulic system component 10 can stably supply or recover hydraulic oil to the cylinder 9 via oil pipes, ensuring smooth extension and retraction of the cylinder 9. Simultaneously, through the electrical connection with the remote control system component 11, the solenoid valves within the hydraulic system can be remotely controlled via a remote controller to switch directions, thereby controlling the movement of the cylinder 9 and ultimately achieving remote opening and closing of the grab bucket. This avoids the cumbersome manual operation of traditional rope grab buckets and ensures the reliability of hydraulic transmission, meeting the needs of efficient timber loading and unloading at port terminals.

[0024] Example 3: like Figure 1-4 As shown, as an improvement to the previous embodiment, this is done in order to meet the requirements for long-term stable operation of the equipment.

[0025] Specifically, the wire rope 2 passes through the guide rope device 4 and the upper support beam 3 and is sleeved on the outside of the pulley 17. The wire rope 2 is folded back by the pulley 17 and fixedly connected to the inclined wedge 15 inside the fixed wedge sleeve 14. The advantages are that the guide rope device 4 can limit the direction of the wire rope 2, preventing the wire rope from deviating and getting stuck. After the wire rope 2 is folded back by the pulley 17, it forms a double-ratio force structure, effectively reducing the amount of rope pulling, which is suitable for scenarios where the lifting height of the gantry crane is limited. At the same time, with the cooperation of the fixed wedge sleeve 14 and the inclined wedge 15, the wire rope 2 can be firmly fixed on the upper support beam 3. Moreover, the wedge sleeve fixing method facilitates the disassembly and installation of the wire rope in the later stage, reduces maintenance costs, and meets the requirements of long-term stable operation of the equipment.

[0026] Example 4: like Figure 1-4 As shown, as an improvement on the previous embodiment, in order to further enhance the stability and reliability of the device operation.

[0027] Specifically, the guide rope device 4, sliding seat 6, pulley 17, fixed wedge sleeve 14, inclined wedge 15, small shackle 18, and wire rope 2 are all equipped with two identical components. The fixed wedge sleeve 14 and inclined wedge 15 are symmetrically distributed at the top of the upper support beam 3, and the guide rope device 4 is also symmetrically distributed at the top of the upper support beam 3. The fixed wedge sleeve 14 and inclined wedge 15 and the guide rope device 4 form a cross shape. The advantage is that the symmetrical arrangement of the two sets of components allows the grab bucket to be evenly stressed on both sides when grabbing timber, avoiding the problem of grab bucket tilting and timber falling due to excessive stress on one side. The cross shape optimizes the component layout at the top of the upper support beam 3, avoiding mutual interference between components and ensuring that the functions of wire rope 2 transmission, guide rope limiting, and rope fixing do not affect each other, further improving the stability and reliability of equipment operation and adapting to the high-intensity loading and unloading operation scenarios of port terminals.

[0028] Example 5: like Figure 1-4 As shown, as an improvement to the previous embodiment, in order to achieve stable adjustment of the grab opening.

[0029] Specifically, two identical hydraulic cylinders 9 are provided, symmetrically distributed on both sides of the upper part of the lower support beam 7. The lower end of each cylinder 9 is fixed to the lower support beam 7 with bolts, and the upper end is fixed to the sliding seat 6 with nuts. The sliding seat 6 can slide vertically along the upper support beam 3. The advantage is that the symmetrical distribution of the two hydraulic cylinders 9 provides a uniform locking force for the connection between the lower support beam 7 and the sliding seat 6, ensuring structural stability when grabbing timber and avoiding deformation of the grab bucket caused by the force of a single hydraulic cylinder 9. The vertical sliding design of the sliding seat 6 along the upper support beam 3, combined with the extension and retraction of the hydraulic cylinders 9, can precisely control the lifting and lowering amplitude of the lower support beam 7, thereby achieving stable adjustment of the grab bucket opening. This ensures both the amount of timber grabbed and prevents the grab bucket from hitting the ship.

[0030] Example 6: like Figure 1-4 As shown, as an improvement on the previous embodiment, the opening and closing can be controlled without close contact with the grab bucket.

[0031] Specifically, the remote control system component 11 includes a remote controller and a receiver. The receiver is electrically connected to the solenoid valve of the hydraulic system component 10. The remote controller communicates with the receiver wirelessly. The bucket teeth 8 adopt a narrow grab structure, with a wide grab width of 1.2m to 1.8m and an opening of 3m to 4m. The advantages are that the wireless communication design between the remote controller and the receiver allows operators to control the opening and closing without close contact with the grab, reducing operational safety risks. It also provides rapid operational response and improves loading and unloading efficiency. The narrow structure of the bucket teeth 8 (1.2m to 1.8m width) is suitable for loading smaller vessels, preventing the grab from colliding with the hull. The 3m to 4m opening ensures the amount of timber grabbed in a single operation, achieving a balance between collision prevention and high efficiency, perfectly meeting the customer's needs for loading and unloading timber on small boats.

[0032] Working principle: In use, first connect the long ring 13 on the balance frame 1 to the gantry crane hook. The gantry crane drives the grab bucket to the timber stacking area. At this time, the hydraulic system component 10 supplies oil to the cylinder 9 through the oil pipe. The cylinder 9 retracts and locks the sliding seat 6 tightly to the lower support beam 7. At the same time, the wire rope 2 is led out through the small shackle 18 at the bottom of the balance frame 1, passes through the rope guide device 4 at the top of the upper support beam 3 and the pulley 17 on the sliding seat 6 in sequence, and is then fixed by the fixed wedge sleeve 14 and the inclined wedge 15 of the upper support beam 3. With the help of this double-ratio transmission structure, the gantry crane applies tension through the wire rope 2. With the support of the strut 5 on the bucket teeth 8, the two sets of bucket teeth 8 close to grab the wood. When the grab bucket moves to the designated unloading position (such as a small boat), the operator sends an unloading signal through the remote control of the remote control system component 11. After receiving the signal, the receiver controls the solenoid valve of the hydraulic system component 10 to switch, and the hydraulic oil in the cylinder 9 flows back to the oil tank 16. The cylinder 9 extends and drives the lower support beam 7 to slide vertically down the upper support beam 3. The sliding seat 6 moves synchronously with the movement of the cylinder 9, thereby opening the bucket teeth 8 and unloading the wood to the target position, completing one loading and unloading cycle.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
