[0001] This utility model relates to the field of crane boom technology, and in particular to a crane boom anti-sway structure. Background Technology
[0002] With the development of electronic technology, the poor stability and tendency to sway of crane booms when handling goods is a common technical challenge in crane operation. This swaying not only affects the accuracy and efficiency of operation, but may also bring safety hazards.
[0003] Therefore, this utility model provides a crane boom anti-sway structure. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a crane boom anti-sway structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crane boom anti-sway structure, including a body column, a double set of insert rods passing through the bottom end of the body column, a height adjustment component being provided at the lower middle end of the body column, a movable frame being provided at the bottom middle part of the height adjustment component, and an anti-sway component being installed in the middle of the movable frame.
[0006] The anti-sway component includes a rotary motor. A rotary motor is installed at one right end of the moving frame, and a lead screw is connected to the middle of the rotary motor. A moving block is provided in the middle of the lead screw, and an adjusting slot frame is installed at the bottom of the moving block. A wire threading frame is engaged in the middle of the adjusting slot frame, and fixing screws are threaded through both sides of the wire threading frame. A steel wire rope is threaded through the middle of the wire threading frame.
[0007] The bottom of the anti-sway component is equipped with a load-bearing hook; and the top two sides of the load-bearing hook are provided with mounting slots, and a weight-reinforcing component is installed in the middle of the two sets of mounting slots.
[0008] In a preferred embodiment, the moving block is connected to the lead screw via a rotary motor, and the adjusting slot frame and the threading frame are movably connected.
[0009] The technical effect of adopting the above-mentioned further solution is as follows: A movable frame is set in the middle of the height adjustment component. A rotary motor with an anti-sway component is installed at one end of the middle right side of the movable frame. When the rotary motor is turned on, it drives the lead screw to rotate. When the lead screw rotates, the spiral groove of the lead screw will drive the moving block of the object in contact with it to make linear displacement. This displacement method has the characteristics of precision and stability, effectively preventing the object from swaying due to excessive speed when the object is moved by the crane boom. It precisely controls the direction of displacement. An adjustment slot frame is set at the bottom of the moving block, which can be used to adjust the support width of the wire rope, thereby improving the stability and safety of the wire rope when transporting objects.
[0010] In a preferred embodiment, the wire rope and the threading frame are tightly fitted together, and the adjusting groove frame is fixed to the threading frame by fixing screws.
[0011] The technical effects of adopting the above-mentioned further solutions are as follows: By adjusting the width, it can be ensured that the object is firmly fixed, reducing the risk of slippage or displacement during handling and improving operational safety. According to the size of the goods, the adjustable-width wire rope can adapt to objects of different sizes and shapes, increasing the versatility and flexibility of the handling equipment. By moving the adjusting slot frame on the wire guide frame, the distance between the two sets of adjusting slot frames can be adjusted. After adjustment, the width of the wire rope can be positioned and locked by fixing screws on both sides of the wire guide frame. By setting the adjustable-width wire rope, the weight of the goods can be better distributed, improving the stability during handling and reducing swaying and rocking. Appropriate width adjustment can reduce the vibration of goods during handling and improve the smoothness of operation.
[0012] In a preferred embodiment, the height adjustment component includes an electric telescopic rod. The electric telescopic rod is installed in the inner cavity of the machine body column, and annular through holes are opened at the top and bottom ends of the electric telescopic rod. An upper screw is installed at the upper end of the electric telescopic rod, an upper bracket is installed above the middle section of the electric telescopic rod, a lower bracket is installed below the middle section of the electric telescopic rod, and a lower screw is installed at the lower end of the electric telescopic rod.
[0013] The technical effect of adopting the above-mentioned further solution is that the user can disassemble and use the upper and lower supports with one arm according to the automatic needs. By removing the upper and lower screws inside the collar of the upper and lower supports on the right side of the machine body column, the electric telescopic rod at the right end can be driven to move down, so that the upper and lower supports can be used with one arm, which greatly improves the usage range of the upper and lower supports. The user can adjust the carrying direction of the upper and lower supports by rotating the upper and lower supports in the opposite direction. The top cylinder of the electric telescopic rod has a ring-shaped slot. After rotating the angle of the upper and lower supports, the upper and lower screws are inserted through the middle of the upper and lower supports for locking.
[0014] In a preferred embodiment, the through hole forms a lifting structure with the upper and lower supports via an electric telescopic rod, and the horizontal central axis of the upper support is parallel to the horizontal central axis of the lower support.
[0015] The technical advantages of adopting the above-mentioned further solution are as follows: Both sets of machine body columns are equipped with electric telescopic rods with height adjustment components inside their cavities. The opening of the electric telescopic rods drives the upper and lower supports at the top of the rods to move up and down within the machine body columns. This electric extension and retraction is used to adjust the height or position of the equipment. Automated adjustment significantly reduces adjustment time and improves work efficiency, especially in scenarios requiring frequent height adjustments. The equipment can adapt to various working conditions and needs, increasing its application range and facilitating the handling of objects of different heights. The top cylindrical end of the electric telescopic rod has upper and lower supports at both ends. Upper and lower screws pass through the upper and lower ends of the upper and lower supports respectively, allowing for positioning and locking onto the top of the electric telescopic rod for installation.
[0016] In a preferred embodiment, the weighting component includes triangular blocks, with triangular blocks provided on both sides of the mounting slot, and a card holder connected to the bottom of the triangular blocks.
[0017] The technical effect of adopting the above-mentioned further solution is that a load-bearing hook is provided at the bottom of the wire rope, and a slot is opened on both sides of the top of the load-bearing hook, so as to facilitate the placement of the triangular block of the weight-adding component on the load-bearing hook, thereby increasing the weight of the equipment and improving its stability.
[0018] In a preferred embodiment, the triangular blocks are symmetrically distributed about the center line of the mounting slot, and two sets of the triangular blocks are provided.
[0019] The technical effect of adopting the above-mentioned further solution is that the triangular block holder engages with the mounting slot of the load-bearing hook, and the weight of the two sets of triangular blocks reduces the swaying caused by the handling of goods, avoids the shaking of objects, and ensures that they are kept in the correct position for displacement and handling.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] A movable frame is located at the middle of the height adjustment component. A rotary motor with an anti-sway component is installed at one end of the right side of the movable frame. Turning on the rotary motor drives the lead screw to rotate. When the lead screw rotates, its helical grooves drive the moving block of the object it contacts to perform linear displacement. This displacement method is precise and stable, effectively preventing the object from swaying due to excessive speed when moved by a crane boom. It precisely controls the direction of displacement. An adjustment slot is located at the bottom of the moving block, which can be used to adjust the support width of the wire rope, improving the stability and safety of the wire rope when handling objects. By adjusting the width, it ensures that the object is securely fixed. The adjustable wire rope reduces the risk of slippage or displacement during handling, improving operational safety. It can accommodate objects of different sizes and shapes, increasing the versatility and flexibility of the handling equipment. The adjustable trough can be moved within the cable threading frame to adjust the distance between the two sets of troughs. After adjustment, the wire rope's width can be locked by fixing screws on both sides of the cable threading frame. The adjustable wire rope allows for better weight distribution, improving stability during handling and reducing swaying and rocking. Appropriate width adjustment reduces vibration during handling, enhancing operational smoothness. Attached Figure Description

[0027] 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.
[0028] Example
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a technical solution: a crane boom anti-sway structure, including a body column 1, a double set of insert rods 2 passing through the bottom end of the body column 1, a height adjustment component 3 provided at the middle and lower end of the body column 1, a movable frame 4 provided at the bottom of the middle part of the height adjustment component 3, and an anti-sway component 5 installed in the middle of the movable frame 4.
[0030] The anti-sway component 5 includes a rotary motor 501. The rotary motor 501 is installed at one right end of the moving frame 4, and a lead screw 502 is connected to the middle of the rotary motor 501. A moving block 503 is provided in the middle of the lead screw 502, and an adjusting slot frame 504 is installed at the bottom of the moving block 503. A wire guide frame 505 is engaged in the middle of the adjusting slot frame 504, and fixing screws 506 are provided on both sides of the wire guide frame 505. A steel wire rope 507 is provided in the middle of the wire guide frame 505.
[0031] The bottom of the anti-sway component 5 is equipped with a load-bearing hook 6; and the top of the load-bearing hook 6 is provided with two mounting slots 7 on both sides, and a weight-reinforcing component 8 is installed in the middle of the two sets of mounting slots 7. Specifically, firstly, the two sets of machine body columns 1 serve as the main support parts of the entire structure, providing stability and height. The two sets of machine body columns 1 are fixed with double-layered double-set plug rods 2 to enhance the stability of the structural installation. The inner cavity of the two sets of machine body columns 1 is provided with an electric telescopic rod 301 of the height adjustment component 3. By opening the electric telescopic rod 301, the upper bracket 304 and lower bracket 305 at the top of the electric telescopic rod 301 are driven to move up and down on the machine body column 1. The extension and retraction are carried out electrically to adjust the height or position of the equipment. Automated adjustment can significantly reduce the need for adjustment. The equipment improves work efficiency, especially in scenarios requiring frequent height adjustments. It adapts to various working conditions and needs, increasing its application range and facilitating the handling of objects at different heights. The top cylindrical section of the electric telescopic pole 301 has upper supports 304 and lower supports 305 at both ends. Upper screws 303 and lower screws 306 are respectively inserted into the upper and lower ends of the upper supports 304 and lower supports 305, allowing for positioning and locking onto the top of the electric telescopic pole 301 for installation. Users can disassemble and use the upper supports 304 and lower supports 305 with a single arm according to automation requirements. The upper screws 303 and lower screws 306 inside the collars of the upper supports 304 and lower supports 305 on the right side of the machine column 1 are then removed. 6. Disassembly: Drive the electric telescopic rod 301 on the right side downwards to allow the upper bracket 304 and lower bracket 305 to be used with a single arm, greatly increasing the usability of the upper bracket 304 and lower bracket 305. The user can adjust the carrying direction of the upper bracket 304 and lower bracket 305 by rotating them in the opposite direction. The top cylindrical part of the electric telescopic rod 301 has an annular groove. After rotating the upper bracket 304 and lower bracket 305, the upper screw 303 and lower screw 306 are inserted through the middle of the upper bracket 304 and lower bracket 305 for locking. The middle of the height adjustment component 3 is provided with a movable frame 4, and the anti-sway component 5 is installed on the right side of the middle of the movable frame 4. Motor 501, when turned on, drives lead screw 502 to rotate. When lead screw 502 rotates, its helical grooves drive the moving block 503 of the object it contacts to perform linear displacement. This displacement method is precise and stable, effectively preventing objects from swaying due to excessive speed when moved by a crane boom. It precisely controls the direction of displacement. The bottom of the moving block 503 is equipped with an adjusting bracket 504, which can be used to adjust the support width of the wire rope 507. This improves the stability and safety of the wire rope 507 when handling objects. By adjusting the width, it ensures that the object is firmly fixed, reducing the risk of slippage or displacement during handling and improving operational safety. The size of the goods can be adjusted accordingly.The adjustable-width wire rope 507 can adapt to objects of different sizes and shapes, increasing the versatility and flexibility of the handling equipment. Moving the adjusting slot frame 504 within the cable threading frame 505 allows for adjustment of the distance between the two sets of adjusting slot frames 504. After adjustment, the width of the wire rope 507 can be locked by inserting fixing screws 506 on both sides of the cable threading frame 505. The adjustable-width wire rope 507 can better distribute the weight of goods, improving stability during handling and reducing swaying and rocking. Appropriate width adjustment can reduce vibration of goods during handling and improve operational smoothness. The bottom end of the wire rope 507 is equipped with a load-bearing hook 6 for load support. Both ends of the hook 6 are provided with mounting slots 7, which facilitate the placement of the triangular blocks 801 of the weight-adding component 8 onto the load-bearing hook 6 to increase the weight of the equipment and improve stability. The brackets 802 of the triangular blocks 801 engage with the mounting slots 7 of the load-bearing hook 6. The weight of the two sets of triangular blocks 801 reduces the swaying caused by the handling of goods, preventing objects from shaking and ensuring that they are kept in the correct position for displacement and handling. This technical solution solves the problem of poor stability and easy swaying of the crane boom when handling goods. The height adjustment component 3 has a moving frame 4 in the middle, and a rotary motor 501 of the anti-sway component 5 is installed at one end of the middle right side of the moving frame 4. The rotary motor 501 drives the lead screw 502 to rotate. When the lead screw 502 rotates, its helical groove drives the moving block 503 of the object it contacts to perform linear displacement. This displacement method is precise and stable, effectively preventing the object from swaying due to excessive speed when moved by a crane boom. It precisely controls the direction of displacement. The bottom of the moving block 503 is equipped with an adjustment slot 504, which can be used to adjust the support width of the wire rope 507. This improves the stability and safety of the wire rope 507 when handling objects. By adjusting the width, it ensures that the object is firmly fixed, reducing the risk of slippage or displacement during handling and improving stability. To ensure operational safety, the adjustable-width wire rope 507 can adapt to objects of different sizes and shapes, increasing the versatility and flexibility of the handling equipment. The adjustment slot frame 504 can be moved within the cable threading frame 505 to adjust the distance between the two sets of adjustment slot frames 504. After adjustment, the width of the wire rope 507 can be locked by fixing screws 506 threaded onto both sides of the cable threading frame 505. The adjustable-width wire rope 507 allows for better weight distribution of goods, improving stability during handling, reducing swaying and rocking, and minimizing vibration during transport, thus improving operational smoothness.
[0032] Going a step further, such as Figure 1-3As shown: The system also includes a height adjustment component 3, comprising an electric telescopic rod 301. The electric telescopic rod 301 is installed inside the cavity of the machine body column 1. The top and bottom ends of the electric telescopic rod 301 have annular through holes 302. An upper screw 303 passes through the upper end of the electric telescopic rod 301. An upper bracket 304 is installed above the middle section of the electric telescopic rod 301, and a lower bracket 305 is installed below the middle section of the electric telescopic rod 301. A lower screw 306 passes through the lower end of the electric telescopic rod 301. The advantage of this technical solution is that both sets of machine body columns 1 have height adjustment components installed inside their cavities. The electric telescopic rod 301 of component 3, when opened, drives the upper bracket 304 and lower bracket 305 at the top of the electric telescopic rod 301 to move up and down on the machine body column 1. The electric telescopic rod extends and retracts electrically to adjust the height or position of the equipment. Automated adjustment significantly reduces adjustment time and improves work efficiency, especially in scenarios requiring frequent height adjustments. The equipment can adapt to various working conditions and needs, increasing its application range and facilitating the handling of objects at different heights. The top cylindrical section has upper brackets 304 and lower brackets 305 at both ends. Upper screws 303 and lower screws 306 are respectively inserted at the upper and lower ends of the upper brackets 304 and lower brackets 305, allowing them to be positioned and locked onto the top of the electric telescopic rod 301 for installation. Users can disassemble and use the upper brackets 304 and lower brackets 305 with one arm according to automation needs. By removing the upper screws 303 and lower screws 306 from the collar of the upper brackets 304 and lower brackets 305 on the right side of the machine body column 1, the electric telescopic rod 301 on the right side can be driven to move downwards. The upper support 304 and the lower support 305 can be used with a single arm, greatly increasing their usability. Users can adjust the carrying direction of the upper support 304 and the lower support 305 by rotating them in opposite directions. The top cylinder of the electric telescopic rod 301 has an annular groove. After rotating the upper support 304 and the lower support 305, the upper screw 303 and the lower screw 306 are inserted through the middle of the upper support 304 and the lower support 305 for locking.
[0033] The above solutions also have the problem of not being able to better control the stability of object movement, such as... Figure 1 , Figure 2 and Figure 3As shown: In this solution, the weight-reinforcing component 8 includes triangular blocks 801. Triangular blocks 801 are provided on both sides of the mounting slot 7, and the bottom end of the triangular blocks 801 is connected to a bracket 802. The bottom end of the wire rope 507 is provided with a load-bearing hook 6. The top of both sides of the load-bearing hook 6 is provided with mounting slots 7, which facilitates the placement of the triangular blocks 801 of the weight-reinforcing component 8 on the load-bearing hook 6, thereby increasing the weight of the equipment and improving stability. The brackets 802 of the triangular blocks 801 are engaged in the mounting slots 7 of the load-bearing hook 6. The weight of the two sets of triangular blocks 801 reduces the swaying caused by the handling of goods, prevents the objects from shaking, and ensures that they are kept in the correct position for displacement and handling.
[0034] Working principle:
[0035] like Figure 1-4 As shown:
[0036] Firstly, two sets of machine body columns 1 serve as the main support components of the entire structure, providing stability and height. These columns are secured using double-layered, double-unit insert rods 2, enhancing the stability of the installation. Each set of machine body columns 1 has an electric telescopic rod 301 with a height adjustment component 3 installed within its inner cavity. Opening the electric telescopic rod 301 drives the upper bracket 304 and lower bracket 305 at the top of the rod to move up and down on the machine body column 1. This electric extension and retraction adjusts the height or position of the equipment. Automated adjustment significantly reduces adjustment time and improves work efficiency, especially in scenarios requiring frequent height adjustments. The equipment can adapt to various working conditions and needs, increasing its application range and facilitating future modifications. For handling objects of different heights, the electric telescopic rod 301 has upper supports 304 and lower supports 305 at both ends of its top cylindrical section. Upper screws 303 and lower screws 306 pass through the upper and lower ends of the upper supports 304 and lower supports 305 respectively, allowing for positioning and locking onto the top of the electric telescopic rod 301 for installation. Users can disassemble and use the upper supports 304 and lower supports 305 with a single arm as needed. By removing the upper screws 303 and lower screws 306 from the collar of the upper supports 304 and lower supports 305 on the right side of the machine body column 1, and driving the electric telescopic rod 301 on the right side downwards, the upper supports 304 and lower supports 305 can be used with a single arm, greatly improving the efficiency of the upper supports 304 and lower supports 305. The user can adjust the carrying direction of the upper and lower supports 304 and 305 by rotating them in opposite directions. The top cylindrical part of the electric telescopic rod 301 has an annular groove. After rotating the upper and lower supports 304 and 305, they are locked in place by upper screws 303 and lower screws 306. A movable frame 4 is located in the middle of the height adjustment component 3. A rotary motor 501 with an anti-sway component 5 is installed at one right end of the movable frame 4. Turning on the rotary motor 501 drives the lead screw 502 to rotate. When the lead screw 502 rotates, its helical groove drives the moving block 50 of the object it contacts. 3. Linear displacement is performed. This displacement method is precise and stable, effectively preventing objects from swaying due to excessive speed when moved by a crane boom. It precisely controls the direction of displacement. The bottom of the moving block 503 is equipped with an adjusting groove 504, which can be used to adjust the support width of the wire rope 507. This improves the stability and safety of the wire rope 507 when handling objects. By adjusting the width, it ensures that the object is firmly fixed, reducing the risk of slippage or displacement during handling and improving operational safety. The adjustable wire rope 507 can adapt to objects of different sizes and shapes, increasing the versatility and flexibility of the handling equipment. The adjusting groove 504 is moved within the wire threading frame 505.The spacing between the two sets of adjustable slot frames 504 can be adjusted. After adjustment, the width of the wire rope 507 can be locked by fixing screws 506 passing through both sides of the wire guide frame 505. The adjustable width of the wire rope 507 allows for better weight distribution of goods, improving stability during handling and reducing swaying and rocking. Appropriate width adjustment reduces vibration during handling and improves operational stability. A load-bearing hook 6 is located at the bottom of the wire rope 507. Slots 7 are provided on both sides of the top of the load-bearing hook 6 to facilitate the placement of the triangular blocks 801 of the weight-adding component 8 onto the load-bearing hook 6, thereby increasing the weight of the equipment and improving stability. The clips 802 of the triangular blocks 801 engage with the slots 7 of the load-bearing hook 6. The weight of the two sets of triangular blocks 801 reduces swaying during handling, preventing objects from shaking and ensuring they remain in the correct position for displacement and handling.
