Description

Technical Field

[0001] This utility model relates to the field of cantilever crane technology, and in particular to a lifting cantilever crane device. Background Technology

[0002] A cantilever crane is a mechanical device used for lifting and transporting goods. It typically consists of a column, a cantilever, and an electric or manual hoist. The column is the supporting component of the cantilever crane, usually installed vertically on the ground or other foundation structure, providing stable support for the entire device. The cantilever is generally a cantilever beam structure, with one end connected to the column and the other end extending freely. The cantilever is usually equipped with a track or pulley system for suspending and moving the lifting tool. The lifting mechanism commonly uses an electric hoist or a manual hoist to achieve the lifting and lowering of goods. Electric hoists are driven by a motor and have a high lifting speed and large lifting capacity, making them suitable for frequent lifting operations. Manual hoists are operated manually, have a simple structure, and are suitable for situations with smaller lifting capacities and infrequent use.

[0003] Traditional hoisting methods often fail to securely fasten the container, leading to shaking, swaying, or even falling during transport. This can damage the container and its contents, potentially causing serious injury to surrounding personnel and equipment, and resulting in safety accidents. Due to concerns about insecure securing, operators frequently need to check and adjust the container or reduce hoisting speed, both of which prolong hoisting time. Furthermore, if rolled materials are not securely fastened, they may rub or collide with other objects during hoisting, causing surface wear, scratches, deformation, or even breakage, affecting material quality and performance and resulting in economic losses. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting cantilever crane device that can solve the problems of traditional devices that are not securely fixed to the container, making it prone to shaking, swaying, or even falling during hoisting. This not only damages the container and its contents but may also cause serious injury to surrounding personnel and equipment, leading to safety accidents. Due to concerns about the container not being securely fixed, operators need to frequently check and adjust during hoisting or reduce the hoisting speed, which prolongs the hoisting time. If rolled materials are not securely fixed, they will roll, shake, rub against or collide with other objects during hoisting, causing wear, scratches, or even deformation and breakage of the material surface, affecting the quality and performance of the material and causing economic losses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lifting cantilever crane device, including a cantilever crane device body, and a fixing component disposed on the outer side of the end of the cantilever crane device body;

[0006] The fixing assembly includes a connecting frame, which is fixedly connected to the outer side of one end of the cantilever crane body. A fixing plate is fixedly connected to the lower surface of the connecting frame. Multiple sliding rods are fixedly connected to the outer side of the end of the fixing plate. A base plate is fixedly connected to the outer side of the bottom end of each sliding rod. An upper pressure plate is slidably connected to the outer side of the outer side of the sliding rod. A first rotating arm is rotatably connected to the outer side of the end of the fixing plate. A second rotating arm is rotatably connected to the inner side of one end of the first rotating arm. The outer side of one end of the second rotating arm is rotatably connected to the inner side of one end of the upper pressure plate. A third rotating arm is rotatably connected to the outer side of the other end of the second rotating arm. Connecting blocks are rotatably connected to the inner sides of the ends of the two third rotating arms. Clamping assemblies are provided on the outer sides of both ends of the base plate.

[0007] In a preferred embodiment, a telescopic cylinder is installed on one side of the fixing plate, and the outer side of the end of the telescopic cylinder is fixedly connected to one side of the connecting block.

[0008] In a preferred embodiment, multiple sets of anti-slip strips are fixedly connected to the upper surface of the base plate, and the anti-slip strips are made of rubber.

[0009] In a preferred embodiment, a placement frame is fixedly connected to the upper surface of the upper pressure plate.

[0010] In a preferred embodiment, the first rotating arm, the second rotating arm, and the third rotating arm are symmetrically arranged on both sides of the connecting block.

[0011] In a preferred embodiment, the clamping assembly includes a limiting block, which is fixedly connected to the outer sides of both ends of the upper pressure plate. A fixing frame is fixedly connected to the outer sides of both ends of the bottom plate. The outer side of the limiting block is slidably connected to the inner side of the fixing frame. Two sliders are slidably connected to the inner side of the end of the fixing frame. A clamping block is fixedly connected to the upper surface of the slider.

[0012] In a preferred embodiment, one side of the clamping block is provided with an arc-shaped structure.

[0013] In a preferred embodiment, the two sets of clamping blocks are disposed on both sides of the placement frame.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In use, the rubber anti-slip strips increase the friction between the box and the container, making the box more stable and less prone to slipping. After the telescopic cylinder is activated, the coordinated movement of the connecting block, third rotating arm, second rotating arm, and first rotating arm ultimately achieves the downward pressure and fixation of the box by the upper pressure plate. At the same time, the two third rotating arms are on the same axis without any tilting force, and the first and second rotating arms are on the same axis without any tilting force. Furthermore, the third rotating arm is perpendicular to the first and second rotating arms, achieving a self-locking function. This ensures that the box will not loosen or fall during hoisting, guaranteeing the safety and stability of the hoisting. The self-locking function of this device avoids accidents caused by loose parts or box displacement, reducing safety hazards and protecting the safety of operators and equipment. The placement frame on the upper surface of the upper pressure plate can hold items, increasing the storage capacity of the device. Users can place tools and accessories related to hoisting work without needing to prepare additional storage space, improving work efficiency and enhancing the practicality of the device.

[0016] 2. In use, this utility model uses the arc-shaped structure of two clamping blocks to accurately position rolled materials, making it convenient for users to place materials in designated positions and improving operational convenience. The upper pressure plate moves downward, causing the limiting block to move vertically downward. The trapezoidal structure on both sides of the limiting block slides into the trapezoidal groove on one side of the slider, clamping the two sliders together in the middle. This firmly clamps the rolled materials, preventing them from shaking, rolling, or falling during transportation. This clamping method based on sliding connection can automatically adjust the clamping degree according to the diameter of the rolled materials, and has good versatility and adaptability, meeting the transportation needs of rolled materials of various specifications.

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a lifting cantilever crane device, including a cantilever crane device body 1, and a fixing component 2 disposed on the outer side of the end of the cantilever crane device body 1. The fixing component 2 includes a connecting frame 21, which is fixedly connected to the outer side of one end of the cantilever crane device body 1. A fixing plate 22 is fixedly connected to the lower surface of the connecting frame 21. A plurality of sliding rods 23 are fixedly connected to the outer side of the end of the fixing plate 22. A bottom plate 24 is fixedly connected to the outer side of the bottom end of the sliding rods 23. An upper pressure plate 25 is slidably connected to the outer side of the outer side of the end of the fixing plate 22. A first rotating arm 26 is rotatably connected to the outer side of the end of the fixing plate 22. A second rotating arm 27 is rotatably connected to the inner side of one end of the first rotating arm 26. One end of the rotating arm 27 is rotatably connected to the inner end of the upper pressure plate 25. The other end of the second rotating arm 27 is rotatably connected to the third rotating arm 28. The inner ends of the two third rotating arms 28 are rotatably connected to the connecting blocks 29. Clamping components are provided on the outer ends of the base plate 24. A telescopic cylinder 210 is installed on one side of the fixed plate 22. The outer end of the telescopic cylinder 210 is fixedly connected to one side of the connecting block 29. Multiple anti-slip strips 211 are fixedly connected to the upper surface of the base plate 24. The anti-slip strips 211 are made of rubber. A placement frame 212 is fixedly connected to the upper surface of the upper pressure plate 25. The first rotating arm 26, the second rotating arm 27, and the third rotating arm 28 are symmetrically arranged on both sides of the connecting block 29.

[0026] When using the device, the user can move the fixing component 2 to a designated position. The user can then place the box to be fixed on the upper surface of the base plate 24. The rubber anti-slip strip 211 increases the friction of the box components. The telescopic cylinder 210 is then activated, increasing its length and pushing the two third rotating arms 28 to rotate via the connecting block 29 until they are on the same axis. The third rotating arms 28 then push the second rotating arms 27 outwards until the first rotating arm 26 and the second rotating arm 27 are on the same axis. At this point, the box can be fixed by pressing down on the upper pressure plate 25. Simultaneously, the two third rotating arms 28 are on the same axis without any tilting force, and the first rotating arm 26 and the second rotating arm 27 are on the same axis without any tilting separation. Furthermore, the third rotating arm 28 is perpendicular to the first and second rotating arms 26, thus achieving the device's self-locking function. Additionally, items can be placed inside the placement frame 212 on the upper surface of the upper pressure plate 25, increasing the device's storage capacity. The anti-slip strip 211 increases the friction between the box and the container, making the box more stable and less prone to sliding. After the telescopic cylinder 210 is activated, the coordinated movement of components such as the connecting block 29, the third rotating arm 28, the second rotating arm 27, and the first rotating arm 26 ultimately achieves the downward pressing and fixing of the upper pressure plate 25 onto the box. At the same time, the two third rotating arms 28 are on the same axis with no tilting force component, and the first rotating arm 26 and the second rotating arm 27 are on the same axis with no tilting force component. Furthermore, the third rotating arm 28 is aligned with the first rotating arm 26 and the second rotating arm 27. The vertical design enables a self-locking function, ensuring that the container will not loosen or fall during hoisting, thus guaranteeing the safety and stability of the hoisting process. The self-locking function of this device prevents accidents caused by loose parts or displacement of the container, reducing safety hazards and protecting the safety of operators and equipment. The placement frame 212 on the upper surface of the upper pressure plate 25 can hold items, increasing the storage capacity of the device. Users can place tools and accessories related to hoisting work without the need for additional storage space, improving work efficiency and enhancing the practicality of the device.

[0027] like Figure 1 - Figure 4 As shown, the clamping assembly includes a limiting block 213, which is fixedly connected to the outer sides of both ends of the upper pressure plate 25. A fixing frame 214 is fixedly connected to the outer sides of both ends of the bottom plate 24. The outer side of the limiting block 213 is slidably connected to the inner side of the fixing frame 214. Two sliders 215 are slidably connected to the inner side of the end of the fixing frame 214. A clamping block 216 is fixedly connected to the upper surface of the slider 215. An arc-shaped structure is provided on one side of the clamping block 216. The two sets of clamping blocks 216 are arranged on both sides of the placement frame 212.

[0028] When a user needs to transport rolled materials, the material can be placed inside the arc-shaped structure of the two clamping blocks 216. At this time, as the upper pressure plate 25 moves downward, it will drive the limiting block 213 to move vertically downward. The trapezoidal structures on both sides of the limiting block 213 are slidably connected to the trapezoidal through groove on one side of the slider 215. Thus, as the limiting block 213 moves vertically downward, the two sliders 215 will clamp towards the center, thereby clamping and fixing the rolled material. The arc-shaped structure of the two clamping blocks 216 can accurately position the rolled material, making it convenient for the user to place the material. Positioned in a designated location, it improves operational convenience. The upper pressure plate 25 moves downward, causing the limiting block 213 to move vertically downward. The trapezoidal structure on both sides of the limiting block 213 slides into the trapezoidal groove on one side of the slider 215, causing the two sliders 215 to clamp together in the middle. This firmly clamps the rolled material, preventing it from shaking, rolling, or falling during transportation. This clamping method based on sliding connection can automatically adjust the clamping degree according to the diameter of the rolled material, and has good versatility and adaptability, meeting the transportation needs of rolled materials of various specifications.

[0029] Working principle: When using this device, the user can move the fixing component 2 to the designated position. The user can then place the box to be fixed on the upper surface of the base plate 24. The rubber anti-slip strip 211 increases the friction between the box and the user. At this point, the telescopic cylinder 210 is activated, increasing its length. This, through the connecting block 29, pushes the two third rotating arms 28 to rotate until they are on the same axis. The third rotating arms 28 then push the second rotating arm 27 to rotate outwards until the first rotating arm 26 and the second rotating arm 27 are on the same axis. The box is then fixed by the downward pressure of the upper pressure plate 25, while the two third rotating arms 28 are in a fixed position. With no tilting force on the same axis, the first rotating arm 26 and the second rotating arm 27 are on the same axis without any tilting force. At the same time, the third rotating arm 28 is set perpendicular to the first rotating arm 26 and the second rotating arm 27, thus realizing the self-locking function of the device. Items can also be placed inside the placement frame 212 on the upper surface of the upper pressure plate 25, increasing the storage capacity of the device. The rubber anti-slip strip 211 increases the friction between the device and the box, making the box more stable and less prone to sliding. After the telescopic cylinder 210 is activated, the coordinated movement between the connecting block 29, the third rotating arm 28, the second rotating arm 27, the first rotating arm 26, and other components ultimately achieves the downward pressing and fixing of the box by the upper pressure plate 25.Meanwhile, the two third rotating arms 28 are on the same axis with no tilting force component, and the first rotating arm 26 and the second rotating arm 27 are on the same axis with no tilting force component. Furthermore, the third rotating arm 28 is perpendicular to the first rotating arm 26 and the second rotating arm 27, achieving a self-locking function. This ensures that the container will not loosen or fall during hoisting, guaranteeing the safety and stability of the hoisting process. The self-locking function of this device avoids accidents caused by loose parts or container displacement, reducing safety hazards and protecting the safety of operators and equipment. The placement frame 212 on the upper surface of the upper pressure plate 25 can hold items, increasing the device's storage capacity. Users can place tools and accessories related to hoisting work without needing additional storage space, improving work efficiency and enhancing the device's practicality. When users need to transport rolled materials, they can place the materials inside the arc-shaped structure of the two clamping blocks 216, at which point the upper pressure plate 25 moves downwards. Simultaneously, the limiting block 213 moves vertically downward. The trapezoidal structures on both sides of the limiting block 213 slide and the trapezoidal groove on one side of the slider 215. As the limiting block 213 moves vertically downward, the two sliders 215 clamp towards the center, thus clamping and fixing the rolled material. The arc-shaped structure of the two clamping blocks 216 can accurately position the rolled material, making it convenient for users to place the material in the designated position and improving the ease of operation. The upper pressure plate 25 moves downward, causing the limiting block 213 to move vertically downward. The sliding connection between the trapezoidal structures on both sides of the limiting block 213 and the trapezoidal groove on one side of the slider 215 clamps the two sliders 215 towards the center, firmly clamping the rolled material and preventing it from shaking, rolling, or falling during transportation. This clamping method based on sliding connection can automatically adjust the clamping degree according to the diameter of the rolled material, and has good versatility and adaptability, which can meet the transportation needs of rolled materials of various specifications.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
