Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a building steel transfer device. Background Technique

[0002] In the construction field, steel plays a crucial role. Among them, steel bars, as common and important building materials, can be seen everywhere on the construction site. These steel bars have various shapes, some are long and thick, and some are short and thin. When dealing with long and thick steel bars, manual handling is inadequate, so it is necessary to rely on hoisting equipment for operation to ensure efficiency and safety. However, for those steel bars with relatively small sizes and diameters, although workers can use small trolleys to assist in handling, it is still a very labor-consuming task.

[0003] Generally, at least two people are required to cooperate to carry such steel bars, respectively lifting the two ends of the steel bar. However, due to the rigidity and weight distribution of the steel bar, when the two ends are lifted, the middle part often sags. Therefore, when placing the steel bar onto the hopper of the small trolley, workers must ensure that the middle part of the steel bar reaches a sufficient height before it can be smoothly dropped into the hopper. This process not only requires workers to have a relatively high lifting height, but also greatly consumes their physical strength, and the efficiency is relatively low.

[0004] Therefore, it is necessary to design a building steel transfer device. Content of the Utility Model

[0005] In order to overcome the drawback that when the two ends are lifted due to the rigidity and weight distribution of the steel bar, the middle part often sags, the utility model provides a building steel transfer device.

[0006] A building steel transfer device includes a vehicle frame and a feeding plate. On the left side of the bottom of the vehicle frame, moving wheels are symmetrically installed. On both sides of the top of the vehicle frame, guiding blocks are symmetrically arranged in the front and rear. Between the four guiding blocks, a feeding plate is elastically connected through a first reset spring. It also includes a limiting block, a guiding cylinder, a sliding rod and an auxiliary plate. Limiting blocks are arranged on both sides of the top of the feeding plate. Guiding cylinders are symmetrically arranged on the left and right of the bottom of the feeding plate. Inside the guiding cylinders, a group of sliding rods are elastically connected through a second reset spring. The number of a group of sliding rods is two, and the two sliding rods are symmetrically arranged in the front and rear. Between the outer ends of the two sliding rods on both sides facing the outside, an auxiliary plate for increasing the stress area is connected.

[0007] Furthermore, it also includes a connecting rod and a guiding plate. On the outer side of the close ends of a group of sliding rods, a connecting rod is provided. On the left and right sides of the top of the vehicle frame, guiding plates are provided. The top of the guiding plate is designed as a plane, and the two sides of the guiding plate are in a downward inclined shape. The guiding plate contacts with the adjacent two connecting rods.

[0008] Further, it also includes a fixed block I, a fixed block II, a scroll spring and a return spring III. A fixed block I is rotatably provided on the upper right side of the frame through a fixed shaft. A fixed block II is slidably provided in the fixed block I. A scroll spring is connected to the rotational connection between the fixed block I and the inside of the fixed shaft. A return spring III is connected to the sliding connection between the fixed block I and the fixed block II.

[0009] Further, it also includes a grip. A grip is connected to the upper left side of the frame through a hinge.

[0010] Further, a chute is provided on the outer side of the guide cylinder. The connecting rod extends out of the chute on the guide cylinder and is slidably matched with it.

[0011] Further, the end of the fixed block II is designed in an inverted hook shape. A fixing rod is provided between the tops of the two guide blocks on the right side. The end of the fixed block II forms a clamping fit with the fixing rod.

[0012] The beneficial effects and remarkable progress of the present utility model are as follows:

[0013] When the steel is placed, its gravity will act on the material placing plate, causing the guide cylinder, the sliding rod and the auxiliary plate to move downward synchronously. At the same time, the connecting rod will push the sliding rod to extend outward under the action of the guide plate, and the return spring II will be stretched due to this extension. As the sliding rod extends, the auxiliary plate will also expand outward and be in close contact with the surface of the steel. This design not only effectively increases the support area of the steel, but also prevents the middle part of the steel from sagging due to uneven stress, thus significantly improving the stability and safety during the transportation process.

Specific implementation manners

[0020] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0021] Embodiment: A building steel transfer device, referring to Figures 1 to 5, including a frame 1, moving wheels 2, a grip 3, guide blocks 4, a feeding plate 5, a return spring I 6, limit blocks 7, guide cylinders 8, sliding rods 9, auxiliary plates 10, a return spring II 11, connecting rods 12, guide plates 13, fixed shafts 14, fixed blocks I 15, fixed blocks II 16, a scroll spring 17 and a return spring III 18. On the left side of the bottom of the frame 1, moving wheels 2 are symmetrically installed. On the right side of the bottom of the frame 1, auxiliary wheels are assembled to ensure the stability and mobility of the transfer device. On the left side of the upper part of the frame 1, a grip 3 is connected through a hinge. The grip 3 facilitates the pushing of the entire transfer device and provides convenience for the transfer work of the operator. On the left and right sides of the top of the frame 1, guide blocks 4 are symmetrically connected in the front and back. Between the interiors of the four guide blocks 4, a feeding plate 5 is elastically connected through a return spring I 6. The surface of the feeding plate 5 is provided with round surface bumps to increase the friction between the feeding plate 5 and the steel, playing an anti-slip role. On the front and rear sides of the top of the feeding plate 5, limit blocks 7 are connected. The limit blocks 7 are evenly provided with grooves adapted to the insertion of the steel. On the left and right sides of the bottom of the feeding plate 5, guide cylinders 8 are fixedly connected through bolts. Inside the guide cylinders 8, a group of sliding rods 9 are elastically connected through a return spring II 11. The number of a group of sliding rods 9 is two. The two sliding rods 9 are symmetrically arranged in the front and back. Between the outer ends of the two sliding rods 9 on the front side and the rear side facing the outside, auxiliary plates 10 are connected. The extension of the auxiliary plates 10 can provide support for the steel. On the outside of the ends where a group of sliding rods 9 are close to each other, a connecting rod 12 is connected. A chute is opened on the outside of the guide cylinder 8. The connecting rod 12 extends out of the chute on the guide cylinder 8 and is in sliding fit with it, ensuring that the connecting rod 12 can smoothly move on the chute to achieve the sliding function. On the left and right sides of the top of the frame 1, guide plates 13 are connected. The top of the guide plate 13 is designed as a plane, and the front and rear sides of the guide plate 13 are in a downward-sloping shape. This design enables the guide plate 13 to effectively contact the adjacent two connecting rods 12, thereby guiding the sliding direction of the connecting rod 12 and ensuring the smooth movement of the auxiliary plate 10 along the expected trajectory. On the right side of the upper part of the frame 1, a fixed block I 15 is rotatably connected through a fixed shaft 14. A fixed block II 16 is slidably connected inside the fixed block I 15. Between the rotational connection inside the fixed block I 15 and the fixed shaft 14, a scroll spring 17 is connected. Between the sliding connection between the fixed block I 15 and the fixed block II 16, a return spring III 18 is connected. The end of the fixed block II 16 is designed in an inverted hook shape. Between the tops of the two guide blocks 4 on the right side, a horizontal fixed rod is connected. The end of the fixed block II 16 can form a clamping fit with the fixed rod. When the inverted hook-shaped end of the fixed block II 16 is accurately docked with the fixed rod, the clamping effect between the two can effectively lock the fixed block II 16 to prevent its accidental movement, thereby ensuring the stability of the entire device.

[0022] When steel needs to be transported, the operator pushes the grip 3 to drive the frame 1 and the moving wheels 2 to move. The moving wheels 2 rub against the ground and rotate, enabling the entire transportation equipment to move smoothly to the designated location. After reaching the destination, an appropriate amount of steel is placed on the discharging plate 5 in sequence. Due to the design of the limit blocks 7 on the discharging plate 5, the two ends of the steel can sink into the limit blocks 7, effectively preventing the steel from rolling during transportation.

[0023] When placing the steel, the discharging plate 5 is subjected to the gravitational force and slides down along the guiding block 4, and the reset spring I 6 is compressed accordingly. During this process, the discharging plate 5 drives the guiding cylinder 8, the sliding rod 9, and the auxiliary plate 10 to move downward synchronously. Under the guidance of the guiding plate 13, the connecting rod 12 drives the sliding rod 9 to extend outwards, the reset spring II 11 is stretched, and the auxiliary plate 10 unfolds outwards, so that the auxiliary plate 10 can contact the steel, thereby increasing the supporting area of the steel, preventing the middle part of the steel from sinking downward, and ensuring the stability during transportation.

[0024] In order to further improve the safety of steel transportation, the fixed block I 15 can be rotated to a position close to the steel. The scroll spring 17 deforms under force, assisting in pulling out the fixed block II 16, so that the barbed end of it hooks the fixed rod on the guiding block 4, and at the same time the reset spring III 18 is stretched. In this way, the fixed block II 16 contacts the steel surface and applies pressure, playing an additional limiting role.

[0025] When discharging, first pull the fixed block II 16 outwards to separate the barbed end from the fixed rod. Subsequently, slightly lift and release the fixed block II 16, and it will retract into the fixed block I 15 under the action of the reset of the reset spring III 18. At the same time, the fixed block I 15 will automatically reset under the action of the scroll spring 17. Next, unload the steel on the discharging plate 5 in sequence. As the steel decreases, the weight of the discharging plate 5 decreases, and the reset spring I 6 drives the discharging plate 5, the guiding cylinder 8, the sliding rod 9, and the auxiliary plate 10 to reset upwards. The connecting rod 12 moves upwards under the guidance of the guiding plate 13, and the reset spring II 11 assists the sliding rod 9 to reset inwards along the guiding cylinder 8, restoring the entire transportation equipment to the initial state.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
