Description

Technical Field

[0001] This application relates to the technical field of lifting tools, and specifically to a new type of C-shaped steel lifting tool. Background Art

[0002] With the booming development of the economy and the continuous progress of society, the demand for new energy globally has shown a blowout growth trend. Against this background, the photovoltaic industry, as an important representative of green energy, has an increasingly urgent demand for key materials in its rapid development. Among them, C-shaped steel has become an indispensable core material in the field of photovoltaic brackets due to its simple production process, high production capacity, and stable structure.

[0003] Traditional C-shaped steel bundling and lifting methods mainly rely on ropes for lifting operations. However, rope lifting is limited by its physical properties and operation methods, resulting in a limited number of C-shaped steels lifted at a single time, greatly restricting the lifting efficiency; secondly, during the rope lifting process, there are relatively high safety hazards such as rope breakage, slippage, or improper operation, which may cause safety accidents; in addition, when C-shaped steels are arranged densely together, due to the narrow and irregular gaps between C-shaped steels, it is often difficult for the sling to pass through these gaps for effective bundling operations, thus increasing the complexity of the lifting operation.

[0004] Therefore, this application provides a new type of C-shaped steel lifting tool to solve the above problems. Utility Model Content

[0005] This application provides a new type of C-shaped steel lifting tool, aiming to solve the problems existing in the existing C-shaped steel rope lifting method in the background art, such as small single-lifting capacity, large safety hazards, and low lifting efficiency.

[0006] To achieve the above object, this application provides the following technical solution: A new type of C-shaped steel lifting tool includes a cross beam, a lifting ring, two connecting cables, two lifting cables, and two lifting positions. The two ends of the two connecting cables are respectively fixedly connected to the upper ends of both sides of the cross beam and the lower ends of both sides of the lifting ring. The two ends of the two lifting cables are respectively fixedly connected to the lower ends of both sides of the cross beam and the top ends of the two lifting positions;

[0007] The lifting position is an inclined C-shaped frame. The opening of the C-shaped frame is located at the higher end of the inclination. The length of the lower beam of the C-shaped frame is at least not less than twice the length of the upper beam of the C-shaped frame;

[0008] The lifting tool further includes an anti-slip plate rotatably arranged on the lower beam of the C-shaped frame near the opening of the C-shaped frame for blocking the C-shaped steel and a driving assembly arranged on the lower beam of the C-shaped frame for flipping the anti-slip plate;

[0009] A receiving groove for accommodating the anti - detachment plate is provided on the lower beam of the C - shaped frame; the opening of the C - shaped frame is located at the end with a higher inclination, and the length of the lower beam is at least not less than twice the length of the upper beam. This design makes it easier for the C - shaped steel to slide into the C - shaped frame naturally during the hoisting process, reducing the time and difficulty of manually adjusting the position of the C - shaped steel, improving the hoisting efficiency. At the same time, this inclined design makes the natural center of gravity of the C - shaped steel tend to move towards the lower end when it is placed on the C - shaped frame, making the C - shaped steel not easy to fall out. The combined design of the anti - detachment plate and the driving component enables the driving component to drive the anti - detachment plate to flip up and block the lateral movement of the C - shaped steel when the C - shaped steel is hoisted to the C - shaped frame, preventing it from accidentally falling due to shaking or external forces during the hoisting process, greatly improving the safety of the hoisting operation. The design of the receiving groove ensures the smoothness of the C - shaped steel when it slides into the C - shaped frame, preventing the anti - detachment plate from becoming an obstacle when it is not flipped, thus reducing unnecessary jams and delays.

[0010] Preferably, in order to facilitate the automatic flipping of the anti - detachment plate, the driving component includes a rotating shaft that sequentially passes horizontally through the side of the anti - detachment plate away from the opening of the C - shaped frame and the receiving groove and is rotatably connected to the receiving groove, a sleeve fixedly arranged on the lower beam of the C - shaped frame at a position below one end of the rotating shaft, a notch opened on the side of the sleeve close to the rotating shaft, a rack that is slidably connected in the sleeve and penetrates through the sleeve, a gear fixedly sleeved on the rotating shaft at a position corresponding to the notch and meshing with the rack, and an electric telescopic rod fixedly arranged on the lower beam of the C - shaped frame for driving the rack to slide. The anti - detachment plate is fixedly connected to the rotating shaft; through the drive of the electric telescopic rod, the rack slides in the sleeve, and the gear meshing with the rack rotates accordingly, thereby driving the rotating shaft and the anti - detachment plate fixedly connected thereto to flip. The whole process does not require direct manual operation, realizing the automatic flipping of the anti - detachment plate and improving the work efficiency and operation convenience.

[0011] Preferably, in order to prevent the rack from moving excessively and detaching from the sleeve when the electric telescopic rod drives the rack to move, a baffle is fixedly installed at one end of the rack away from the electric telescopic rod, and the baffle is located outside the sleeve; the design of the baffle makes the baffle contact the end face of the sleeve or adjacent structures when the electric telescopic rod drives the rack to move to the limit position on one side, thereby preventing the rack from continuing to move and preventing the excessive movement and detachment of the rack.

[0012] Preferably, in order to improve the protection of the driving component and not affect the hoisting use of the C - shaped frame, a protective box is fixedly arranged at the position of the lower beam of the C - shaped frame corresponding to the driving component; the protective box provides sufficient protection space for the driving component to prevent the C - shaped steel from contacting and rubbing against the driving component during hoisting, causing damage to the driving component.

[0013] Preferably, in order to ensure the balance of the C-shaped frame during hoisting, a counterweight is fixedly arranged on the side of the lower beam of the C-shaped frame away from the protective box; the design of the counterweight can adjust the center of gravity position of the C-shaped frame, so that it remains horizontal or stable at a predetermined angle during hoisting, avoiding the inclination of the C-shaped frame towards the driving component side, reducing the shaking and inclination caused by the center of gravity deviation, and ensuring the stability and accuracy of the hoisting operation.

[0014] Preferably, in order to prevent the anti-detachment plate from over-flipping when retracted into the receiving groove, a limiting plate is fixedly arranged inside the receiving groove and abuts against the end of the anti-detachment plate away from the rotating shaft; when the anti-detachment plate is retracted into the receiving groove, the limiting plate will limit the flipping angle of the anti-detachment plate during the retraction process, thus avoiding over-flipping and affecting the use of the C-shaped frame.

[0015] The new C-shaped steel sling is provided with an inclined C-shaped frame, and the opening of the C-shaped frame is located at the end with a higher inclination. The length of the lower beam is at least not less than twice the length of the upper beam, so that the C-shaped steel is more likely to slide into the C-shaped frame naturally during hoisting, reducing the time and difficulty of manually adjusting the position of the C-shaped steel, improving the hoisting efficiency. At the same time, this inclined design makes the natural center of gravity of the C-shaped steel tend to move towards the lower end when placed on the C-shaped frame, making the C-shaped steel not easy to fall out;

[0016] The new C-shaped steel sling is provided with an anti-detachment plate and a driving component. When the C-shaped steel is hoisted to the C-shaped frame, the driving component can drive the anti-detachment plate to flip up and block the lateral movement of the C-shaped steel, preventing it from accidentally falling during hoisting due to shaking or external force, greatly improving the safety of the hoisting operation;

[0017] The new C-shaped steel sling is provided with a receiving groove, which can ensure the smoothness of the C-shaped steel when sliding into the C-shaped frame, prevent the anti-detachment plate from becoming an obstacle when not flipped, and thus reduce unnecessary jams and delays.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] This embodiment provides a new type of C-shaped steel lifting tool, as Figures 1-4 shown. The lifting tool includes a cross beam 1, a suspension ring 2, two connecting cables 3, two suspension ropes 4 and two lifting positions 5. The two ends of the two connecting cables 3 are respectively fixedly connected to the upper ends of both ends of the cross beam 1 and the lower ends of both ends of the suspension ring 2. The two ends of the two suspension ropes 4 are respectively fixedly connected to the lower ends of both ends of the cross beam 1 and the top ends of the two lifting positions 5. The lifting position 5 is an inclined C-shaped frame 51, and the opening of the C-shaped frame 51 is located at the higher end of the inclination. The length of the lower beam of the C-shaped frame 51 is at least not less than twice the length of the upper beam of the C-shaped frame 51. The lifting tool further includes an anti-drop plate 6 rotatably arranged on the lower beam of the C-shaped frame 51 near the opening of the C-shaped frame 51 for blocking the C-shaped steel, and a driving assembly 7 arranged on the lower beam of the C-shaped frame 51 for flipping the anti-drop plate 6. An accommodating groove 511 for accommodating the anti-drop plate 6 is arranged on the lower beam of the C-shaped frame 51.

[0034] In use, connect the lifting ring 2 to a crane or other hoisting equipment. During hoisting, use the crane or other hoisting equipment to lift the entire sling through the lifting ring 2 and move it above the C-shaped steel to be hoisted. Then, align the opening of the C-shaped frame 51 with one end of the C-shaped steel, and slowly lower the sling so that the C-shaped steel gradually enters the C-shaped frame 51. When the C-shaped steel is completely inside the C-shaped frame 51 and stable, start the driving component 7 to activate the anti-drop plate 6, making it flip to a vertical state and block the other end of the C-shaped steel, thus realizing the fixation and prevention of the C-shaped steel from falling off. After that, use the crane or other hoisting equipment to lift through the lifting ring 2. After lifting, since the C-shaped frame 51 is inclined, and the opening of the C-shaped frame 51 is at the higher end of the inclination, and the length of the lower beam is at least not less than twice the length of the upper beam, therefore, the C-shaped frame 51 will tilt backward to the lower end of the inclination due to gravity to further prevent the C-shaped steel from falling. Finally, after hoisting the C-shaped steel to the designated position, use the driving component 7 again to flip the anti-drop plate 6 back and retract it into the receiving groove 511, and then slowly lower the sling so that the C-shaped steel slides out of the C-shaped frame 51 and is safely unloaded.

[0035] Specifically, the driving component 7 includes a rotating shaft 71 that sequentially passes horizontally through the side of the anti-drop plate 6 away from the opening of the C-shaped frame 51 and the receiving groove 511 and is rotatably connected to the receiving groove 511, a sleeve 72 fixedly arranged at a position below one end of the rotating shaft 71 on the lower beam of the C-shaped frame 51, a notch 73 opened on the side of the sleeve 72 close to the rotating shaft 71, a rack 74 slidably connected in the sleeve 72 and passing through the sleeve 72, a gear 75 fixedly sleeved on the rotating shaft 71 at a position corresponding to the notch 73 and meshing with the rack 74, and an electric telescopic rod 76 fixedly arranged on the lower beam of the C-shaped frame 51 for driving the rack 74 to slide. The anti-drop plate 6 is fixedly connected to the rotating shaft 71;

[0036] When the C-shaped steel is completely inside the C-shaped frame 51 and stable, start the electric telescopic rod 76 to push the rack 74 to slide in the sleeve 72. Since the rack 74 meshes with the gear 75 fixed on the rotating shaft 71, therefore, as the baffle 741 slides, the gear 75 will start to rotate. Then, as the gear 75 rotates, it can synchronously drive the rotating shaft 71 to rotate. At this time, the anti-drop plate 6 connected to the rotating shaft 71 will flip to a vertical state with the rotating shaft 71 as the axis. After that, pause the electric telescopic rod 76, and the flipping of the anti-drop plate 6 will form a block at the other end of the C-shaped steel. When the C-shaped steel needs to slide out of the C-shaped frame 51 and be safely unloaded, the electric telescopic rod 76 can be started again to drive the rack 74 to slide reversely in the sleeve 72. At this time, as the rack 74 slides, the meshing gear 75 will drive the rotating shaft 71 to rotate reversely, so that the rotating shaft 71 will drive the anti-drop plate 6 to flip reversely and retract into the receiving groove 511, without forming a block with the opening of the C-shaped frame 51.

[0037] Among them, in order to prevent the rack 74 from moving excessively and disengaging from the sleeve 72 when the electric telescopic rod 76 drives the rack 74 to move, a baffle 741 is fixedly installed at one end of the rack 74 away from the electric telescopic rod 76, and the baffle 741 is located outside the sleeve 72; due to the design of the baffle 741, when the electric telescopic rod 76 drives the rack 74 to move to the extreme position on one side, the baffle 741 will contact the end face of the sleeve 72 or the adjacent structure, thereby preventing the rack 74 from continuing to move and preventing the excessive movement and disengagement of the rack 74.

[0038] In addition, in order to improve the protection of the drive assembly 7 without affecting the hoisting use of the C-shaped frame 51, a protective box 8 is fixedly arranged at the position of the lower beam of the C-shaped frame 51 corresponding to the drive assembly 7; the protective box 8 provides sufficient protection space for the drive assembly 7 to prevent the C-shaped steel from contacting and rubbing against the drive assembly 7 during hoisting, causing damage to the drive assembly 7.

[0039] Moreover, in order to ensure the balance of the hoisting of the C-shaped frame 51, a counterweight 9 is fixedly arranged on the side of the lower beam of the C-shaped frame 51 away from the protective box 8; due to the design of the counterweight 9, the center of gravity position of the C-shaped frame 51 can be adjusted to keep it horizontal or stable at a predetermined angle during hoisting, avoiding the C-shaped frame 51 from tilting towards the drive assembly 7 side, reducing the shaking and tilting caused by the center of gravity deviation, and ensuring the stability and accuracy of the hoisting operation.

[0040] Furthermore, a limiting plate 5111 is fixedly arranged inside the receiving groove 511 and abuts against one end of the anti-disengagement plate 6 away from the rotating shaft 71; when the drive assembly 7 is started to drive the anti-disengagement plate 6 to flip and retract into the receiving groove 511, due to the limitation of the limiting plate 5111, after the anti-disengagement plate 6 flips into the receiving groove 511 and abuts against the limiting plate 5111, the driving of the drive assembly 7 can be paused, which can prevent the anti-disengagement plate 6 from flipping excessively.

[0041] The above is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent replacement or change, and should be covered by the protection scope of the present application.
