[0002] Rebar is a kind of steel product commonly used in construction projects. According to different production processes, it can be divided into finished and semi-finished products. Semi-finished products refer to the pre-finished products, that is, the steel products that have undergone preliminary processing but have not yet been fully formed. Semi-finished products are generally produced by steel mills. After rolling, cold drawing, shearing and other processing, they are delivered to construction steel processing plants for subsequent processing and finished product production.
[0003] At present, semi-finished steel components are indispensable in the main structure construction stage. However, a series of problems are often encountered during the binding process of the semi-finished steel components, such as the components are difficult to move, which hinders the lifting and placement of other components, and it is difficult for workers to move them during construction. These problems will not only increase the transportation time during construction, but also increase the safety hazards such as collapse caused by the transportation of components during construction. Moreover, when conventional handling devices are used to pick up and place materials inside, the materials on the bottom side are limited by the obstruction of the surrounding structures, making it extremely laborious and inconvenient to pick up and place, resulting in affected work efficiency.
[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a device for improving the efficiency of semi-finished steel bar transportation is proposed. Utility Model Content

[0014] The utility model provides a device for improving the transfer efficiency of semi - finished steel bars, which has the following beneficial effects:
[0015] 1. In the utility model, the semi - finished steel bars are lifted and placed on the surface of the storage steel plate by an external hoisting device. Then, as the semi - finished steel bars are placed, the storage steel plate, the damping columns and the support springs at its bottom will gradually press down vertically with the increase of the material, and ensure that the upper part remains in a plane. Subsequently, when taking the semi - finished steel bars, as the weight of the taken material gradually decreases, the storage steel plate will rise with the rebound of the damping columns and the support springs, keeping the upper semi - finished steel bars in a plane, thus reducing the need to bend down to take. At the same time, through the adjustment of the adjustable damping shaft structure, the upper hollow - plate frame connected to the top of the lower hollow - plate frame can be folded left and right in the vertical direction, so as to reduce the structural interference of the adjustment frame group during the process of taking or placing materials, facilitate the access of semi - finished steel bars, and improve the flexibility and convenience of the device structure.

[0016] 2. The utility model, through the movable wheel group installed at the bottom of the device chassis, the combination of the steering shaft and the self-locking wheel makes the whole transport device flexibly movable. When the whole device needs to keep the position fixed, the locking structure of the self-locking wheel can be opened by pressing the locking pedal with the foot, avoiding the need to bend over to open the locking structure. At the same time, by rotating the screw rod vertically running through the upper buffer frame and the lower buffer frame, the support block at the bottom is pressed against the ground, so that the whole device is positioned and supported on the ground, so as to further improve the stability of the whole device and avoid safety hazards such as landslides. The upper buffer frame and the lower buffer frame also play a certain role in collision buffering in the event of landslides, reducing collision damage. In addition, a supporting wheel group is arranged at the bottom center of the device chassis. The buffer column at the top of the stabilizing frame is used in combination with the use of universal wheels, which can provide bottom support for the device chassis without causing structural interference to the movement, thereby ensuring sufficient stability and flexibility.

DETAILED DESCRIPTION
[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0023] like Figures 1 to 4 As shown in the figure, a device for improving the transfer efficiency of semi-finished steel bars includes a device chassis 1 and a storage rack group 5. An adjustment rack group 2 is provided around the device chassis 1, and a stabilizing component 3 is installed on the side of the adjustment rack group 2 away from the device chassis 1. Moreover, a steel pipe handrail 4 is arranged above the stabilizing component 3. The storage rack group 5 is installed on the top of the device chassis 1, and movable wheel groups 6 are installed on the left and right sides of the bottom of the device chassis 1. Moreover, support wheel groups 7 are installed on both sides of the bottom of the device chassis 1. The storage rack group 5 includes a storage steel plate 501, a sliding rack 502, a damping column 503, and a support spring 504. Sliding racks 502 are slidably connected to both the left and right sides of the storage steel plate 501, and damping columns 503 are vertically installed at the bottom of the storage steel plate 501. Moreover, support springs 504 are sleeved outside the damping columns 503. The sliding racks 502 are vertically and closely installed on the side of the lower hollow plate rack 201 away from the stabilizing component 3, and the sliding racks 502 and the storage steel plate 501 are connected in an "H" - shaped structure. The adjustment rack group 2 includes a lower hollow plate rack 201, an upper hollow plate rack 202, and an adjustable damping shaft 203. The upper hollow plate rack 202 is arranged on the top of the lower hollow plate rack 201, and the upper hollow plate rack 202 and the lower hollow plate rack 201 are connected by an adjustable damping shaft 203. The adjustment rack group 2 is welded to the device chassis 1, and the adjustment rack group 2 and the device chassis 1 are connected in a "凵" - shaped structure. The semi - finished steel bars are hoisted and placed on the surface of the storage steel plate 501 by an external hoisting device. Then, as the semi - finished steel bars are put in, the storage steel plate 501 and the damping columns 503 and support springs 504 at its bottom will gradually press down vertically with the increase of the material, ensuring that the upper part remains in a plane. Subsequently, when taking the semi - finished steel bars, as the weight of the material taken gradually decreases, the storage steel plate 501 will be jacked up under the elastic return of the damping columns 503 and support springs 504 to keep the upper semi - finished steel bars in a plane, thus reducing the need to bend down to pick up.
[0024] The stabilizing assembly 3 includes an upper buffer frame 301, a lower buffer frame 302, a screw rod 303 and a support block 304. The lower buffer frame 302 is arranged below the upper buffer frame 301, and the screw rod 303 is vertically threadedly installed between the lower buffer frame 302 and the upper buffer frame 301, and the support block 304 is installed at the bottom of the screw rod 303. The movable wheel group 6 includes a steering shaft 601, a self-locking wheel 602 and a locking pedal 603. The self-locking wheel 602 is installed at the bottom of the steering shaft 601, and a locking pedal 603 is connected to one side of the self-locking wheel 602. The movable wheel group 6 is installed at the four diagonal positions at the bottom of the device chassis 1, and the supporting wheel group 7 is installed at the bottom center of the device chassis 1. The supporting wheel group 7 includes a stabilizing frame 701, a buffer The top of the stabilizing frame 701 is provided with a buffer column 702, and the bottom of the stabilizing frame 701 is provided with a universal wheel 703. By installing a movable wheel group 6 at the bottom of the device chassis 1, the steering shaft 601 and the self-locking wheel 602 are used in combination, so that the entire transport device can be moved flexibly. When it is necessary to keep the entire device in a fixed position, it is only necessary to press the locking pedal 603 with the foot to open the locking structure of the self-locking wheel 602, avoiding the need to bend over to open the locking structure. At the same time, by rotating the screw rod 303 that vertically passes through the upper buffer frame 301 and the lower buffer frame 302, the support block 304 at the bottom is pressed against the ground, so that the entire device is positioned and supported on the ground.
[0025] In summary, if Figures 1 to 4 As shown, when using the device for improving the efficiency of transporting semi-finished steel bars, the user can first press the locking pedal 603 on one side of the self-locking wheel 602 with his foot to keep the entire movable wheel set 6 in a locked state, and then axially rotate the screw rod 303 that vertically penetrates the upper buffer frame 301 and the lower buffer frame 302 in the vertical direction, and make the support block 304 at the bottom of the screw rod 303 rest on the ground from top to bottom, and use the stabilizing component 3 to ensure that the entire device can be stably parked on the ground.
[0026] By adjusting the adjustable damping shaft 203, the upper hollow plate frame 202 at the upper end of the lower hollow plate frame 201 is folded and adjusted in the vertical direction toward the side away from the vertical central axis of the device chassis 1, so as to facilitate the placement of materials. Then, the hoisted semi-finished steel bars are placed on the surface of the placement steel plate 501. As the amount of materials placed increases, under the action of weight, the placement steel plate 501 will be vertically pressed down along the surface of the sliding frame 502, and the damping column 503 and the support spring 504 will be structurally compressed;
[0027] When the semi-finished steel bars to be transported are placed, the adjustment frame group 2, the stabilizing assembly 3 and the movable wheel group 6 are reset, and under the structural movement of the movable wheel group 6 and the supporting wheel group 7, the steel pipe handrail 4 is pushed to move the entire device with the semi-finished steel bars placed thereon to the position where the semi-finished steel bars need to be tied. During the movement, the buffer columns 702 and the universal wheels 703 on the upper and lower sides of the stabilizing frame 701 can provide structural mobility and support at the same time, and then the above-mentioned structural adjustment method is used to stabilize the entire device on the ground to prevent safety hazards such as landslides during the unloading process;
[0028] During the unloading process, as the semi-finished steel bars are taken, the weight gradually decreases, and the pressure of the storage steel plate 501 on the damping column 503 and the support spring 504 at the bottom gradually decreases. Therefore, the damping column 503 and the support spring 504 will gradually rebound and cause the top storage steel plate 501 to rise accordingly, thereby keeping the upper semi-finished steel bars in a plane, thereby reducing the need to bend over to unload, until all the materials inside are completely taken out.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
