Technical Field
[0001] The invention relates to the technical field of hoisting equipment, in particular to a steel bar hoisting equipment. Background Art
[0002] Lifting is an operation involving many details and steps. Before carrying out the lifting operation, careful planning is required. First, the weight, shape, size and center of gravity of the lifting object must be determined, and the conditions of the lifting site, such as ground conditions, working space, and safe areas, must be considered. It is very important to establish a suitable lifting plan, including selecting appropriate lifting tools and equipment, determining lifting points, formulating possible risks and countermeasures, etc. In the preparation stage, the safety performance of the lifting equipment and tools must be checked, necessary debugging and installation must be carried out, safety equipment must be prepared, and protective measures must be taken around the site. When implementing the lifting, it is necessary to ensure that the lifting points are The lifting hook or sling should be selected appropriately, the lifting object should be firmly connected to the hook or sling, the lifting should be done slowly and with steady control, the surrounding personnel should be evacuated safely and attention should be paid to observing the lifting process. After the lifting is completed, the condition of the lifting tools and equipment should be checked in time, the fixation of the lifting object should be confirmed, and the site should be cleaned up. In general, lifting is a high-risk operation that requires rigorous planning and strict operating procedures. Only through detailed preparation and strict compliance with various safety regulations can the lifting operation be carried out smoothly and accidents can be avoided. For the lifting of steel bars, it is necessary to use the two lifting ropes in the crane to bypass multiple steel bars bundled together for lifting.
[0003] A Chinese patent discloses a lifting device for bundled steel bars (authorization announcement number CN104261250B), which includes a lifting ear, a connecting pin, a clamping mechanism, and the clamping mechanism includes two upper connecting rods and two lower claws. The upper ends of the two upper connecting rods are connected by a connecting pin, and the lower end of each connecting rod is connected to a claw through a pin. The middle parts of the two claws are connected by a pin, so that a diamond-shaped connecting rod force transmission mechanism is formed between the parts above the middle of the two claws and the two connecting rods; it also includes a lifting and extending mechanism, which includes a flexible connecting member and a hook. The upper end of the flexible connecting member is connected to the lower part of the lifting ear, and the lower end is connected to the hook; at the same time, a lifting hole is opened on the upper part of the lifting ear and a waist-shaped hole is opened in the middle part. The connecting pin is arranged in the waist-shaped hole of the lifting ear and can move up and down along the waist-shaped hole. When it is necessary to lift bundles of steel bars, first insert the hook into the whole bundle of steel bars and lift it slowly. When the bottom of the waist-shaped hole of the upper lifting ear contacts the connecting pin, the diamond connecting rod force transmission mechanism starts to move and drives the claws to retract inward until the bundle of steel bars is tightly clamped. At this time, the state is the same as that of a round steel sling, and the whole bundle of steel bars can be easily lifted away.
[0004] In the above patent, when lifting bundles of steel bars, it is first necessary to use a hook to fix the entire bundle of steel bars, and fixing requires the entire bundle of steel bars to be wrapped with ropes. The existing method is to arrange the hoisted steel bars horizontally and vertically to leave gaps for the steel bars for later threading of ropes, or to place the steel bars on the ground with grooves. However, these methods not only require the condition that there are gaps around the entire bundle, but also require manual threading of ropes, which is not only dangerous, but also time-consuming and labor-intensive. In addition, when the steel bars are lifted to the target area, the angle of the steel bars needs to be manually adjusted, which undoubtedly increases the risk of injury to the staff.

[0047] Example 2: Please refer to Figure 8 Based on Example 1, the forward and reverse adjustment component 9 includes a short rod 901 welded to the adjustment wheel 7 inside the semicircular box 201 at the rear side, and the opposite ends of the transmission rod 8 and the short rod 901 are fixedly connected with a first bevel gear 902 by bolts, and the two first bevel gears 902 are symmetrically arranged, and the transmission rod 8 and the short rod 901 are rotatably connected to the same cylindrical shell 903, and the two first bevel gears 902 are located inside the cylindrical shell 903, and the inner wall of the cylindrical shell 903 is rotatably connected to the second bevel gear 904, and the second bevel gear 904 is meshed with the two first bevel gears 902, and the left and right side walls of the cylindrical shell 903 Two plug rods 907 are inserted, and the ends of the two pairs of plug rods 907 that are away from each other are fixedly connected to the same disc 906.

A friction plate 910 is fixedly connected between the inner walls on both sides of the semicircular box 201, and the friction plate 910 is located between the two discs 906.
[0048] The working principle of the present invention is:
[0049] Before using the present invention, the hook assembly 3 and the hook ring 4 need to be fixed to the magnet block 205 and the magnetic rod 206 respectively by magnetic adsorption, and the U-shaped groove 304 of the ring block 303 in the hook assembly 3 is rotated to correspond to the notch 302 in the hook 301, and then the forward and reverse motor 106 is started to drive the screw rod 104 to rotate, thereby driving the two moving blocks 105 to move relative to each other. The staff determines the lifting position of the whole bundle of steel bars according to the length of the whole bundle of steel bars, so that the two moving blocks 105 can move to the corresponding position;
[0050] Then the staff controls the lifting device to move the adjustment box 101 to the top of the whole bundle of steel bars to be lifted, and then the staff activates the strong current magnet 103, so that the middle section of the strong current magnet 103 is attracted by the magnetic force of the strong current magnet 103, so that a certain gap is maintained between the strong current magnet 103 and the ground;
[0051] It is worth noting that the weight of the steel bar that can be lifted by the strong current magnet 103 needs to be calculated based on the maximum magnetic force of the strong current magnet 103. In the existing technology, multiple strong current magnets 103 are also used to directly lift the steel bar, but the number of strong current magnets 103 in this application is only one, and its main purpose is to suck up the middle section of the steel bar. Whether in terms of energy consumption or cost, the effect and function brought by this application are different from those of the traditional multiple strong current magnets 103.
[0052] Then the staff starts the driving motor 204 and the electromagnet 604 adjusted to generate repulsive force. The repulsive force generated by the electromagnet 604 pushes the connecting tube 603, so that the first conical block 602 fits with the first conical sleeve 605. At this time, the driving motor 204 drives the guide rod 601 to rotate, and the guide rod 601 drives the gear 203 to rotate through the first conical sleeve 605. The gear 203 drives the semicircular track 202 to rotate, so that the semicircular track 202 drives the hook ring 4 to rotate through the magnetic rod 206, so that the hook ring 4 pushes the U-shaped guide rod 30 After the hook 4 is turned upward, the driving motor 204 starts to reverse, so that the hook ring 4 contacts the upper side wall of the U-shaped guide rod 305. The U-shaped guide rod 305 cannot be turned due to the limit of the stop rod 306. At this time, the hook ring 4 is separated from the magnetic rod 206 and slides down to the inside of the U-shaped groove 304 along the slope of the U-shaped guide rod 305, completing the rope winding step for the whole bundle of steel bars. Finally, the lifting work starts. When the steel rope 5 lifts the whole bundle of steel bars, the annular block 303 is forced to rotate downward, so that the hook ring 4 can be stably hooked into the hook 301;
[0053] It is worth noting that when the hook ring 4 contacts the upper side wall of the U-shaped guide rod 305, the annular block 303 will be subjected to a downward rotation force, but due to the friction resistance between the annular block 303 and the hook 301, the hook ring 4 will not rotate after contacting the U-shaped guide rod 305.
[0054] When the whole bundle of steel bars is hoisted to the target area, the staff can control the electromagnet 604 to generate magnetic attraction. At this time, the electromagnet 604 attracts the connecting pipe 603, so that the first conical block 602 contacts the first conical sleeve 605 close to the transmission shaft 606, thereby driving the first sprocket 607 to rotate;
[0055] It is worth noting that when the front gear 203 rotates, since the first conical sleeve 605 at the second sprocket 609 is rotatably connected to the guide rod 601, the first sprocket 607 does not rotate under the influence of the transmission resistance on the first sprocket 607;
[0056] The second sprocket 609 drives the first sprocket 607 to rotate through the chain 608, and the first sprocket 607 drives the two adjusting wheels 7 to rotate through the transmission rod 8. After the adjusting wheels 7 come into contact with the ground, the adjusting wheels 7 are similar to wheels and play an effective role in adjusting the lateral position of the lifting position;
[0057] When the staff needs to make a lateral adjustment to the whole bundle of steel bars, the staff activates the forward and reverse adjustment component 9 to generate a magnetic repulsive force, so that the electric magnet 909 pushes the two discs 906 to move outward, so that the second conical block 905 contacts the second conical sleeve 908, so that the transmission rod 8 can drive the two discs 906 to rotate, and the two discs 906 drive the cylindrical shell 903 to rotate through the insertion rod 907, thereby driving the adjustment wheel 7 to rotate synchronously;
[0058] When the staff needs to make rotational adjustments to the entire bundle of steel bars, the staff controls the forward and reverse adjustment component 9 to generate magnetic attraction, so that the electric magnet 909 attracts the two discs 906 to move outward, so that the two discs 906 clamp the friction plate 910. At this time, the cylindrical shell 903 becomes non-rotatable, and the transmission rod 8 can drive the first bevel gear 902 to rotate, and then drive the other first bevel gear 902 to rotate through the second bevel gear 904, and finally achieve the purpose of reversing the adjustment wheel 7. When the two adjustment wheels 7 rotate in opposite directions, the purpose of rotating the entire bundle of steel bars can be achieved. If the reversal of the entire bundle of steel bars needs to be achieved, it is only necessary to control the reversal of the drive motor 204.
[0059] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
