Description

Technical Field

[0001] The present application relates to the technical field of steel bar processing equipment, and in particular to a steel bar coil pay-off device. Background Art

[0002] During the construction process, construction workers often need to use steel bars with a diameter of 8-10mm as stirrups. The above-sized steel bars are generally rolled into coils for transportation. Therefore, before processing, construction workers need to straighten the steel coils and then process the steel bars. During the steel straightening process, construction workers generally place the steel coils on the steel wire releaser and rotate the steel coils to reduce the swing amplitude of the steel bars during movement.

[0003] The existing patent with application number 201710659842.1 discloses a thin steel bar pay-out device. It realizes automatic unwinding through a motor, but in actual use, since the steel bars will be pulled during the straightening process, it is necessary to give the steel bars a traction force. Therefore, the unwinding structure needs to be able to rotate flexibly and does not need the automatic unwinding function. Especially when used temporarily on the construction site, the existing steel bar pay-out device has a complex structure. When applied to the construction site, not only is the cost too high, but the electric control operation is also relatively complicated for workers who lack operating experience, which is inconvenient for workers on the construction site to use.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Utility Model Content

[0037] See also Figure 1 , this embodiment proposes a steel bar coil pay-off device for supporting the steel bar coil extracted by the straightening machine. The steel bar coil pay-off device proposed in this embodiment mainly includes: a vehicle tire 100 and a pay-off bracket 200. The vehicle tire 100 is arranged horizontally, and a bearing member 130 is provided at the center position of the vehicle tire 100. The pay-off bracket 200 is connected to the bearing member 130 in the vertical direction, and is rotatably connected to the vehicle tire 100 through the bearing member 130. In the specific structure, the vehicle tire 100 can utilize the vehicle tire 100 of a waste mining cart. Since mining carts are relatively common on construction sites, the tires of damaged and scrapped mining carts can be directly utilized, thereby realizing local material acquisition and saving costs. Moreover, the vehicle tire 100 itself has a bearing member 130, such as a bearing chamber of the tire. The wire-paying bracket 200 is directly connected to the bearing member 130 to realize the rotation of the wire-paying bracket 200. The steel bar coil is placed on the wire-paying bracket 200, and the steel bar coil can be paid out by rotating the wire-paying bracket 200.

[0038] The present embodiment proposes a rebar coil unwinder, which directly uses an abandoned vehicle tire 100 as a base, and connects a unwinding bracket 200 after laying it flat. The unwinding bracket 200 is rotated on the vehicle tire 100 by using the bearing 130 provided by the vehicle tire 100. The unwinding bracket 200 is used to place the rebar coil, and the rebar coil unwinding function is realized by rotating the unwinding bracket 200. And when unwinding, the vehicle tire 100 is flexibly grounded, which has the advantages of being more stable, reducing friction, and being smoother. Therefore, the rebar coil unwinder is manufactured using a vehicle tire 100, and even using an abandoned and discarded cart for modification, so it operates smoothly and saves costs; and it has a simple structure, which is convenient for workers on the construction site to operate, improves work efficiency, and has achieved the expected results through practice.

[0039] See also Figure 1 Furthermore, the vehicle tire 100 in this embodiment specifically includes: a wheel hub 110 and an elastic tire 120. The upper surface of the wheel hub 110 is convex toward the center position, the bearing member 130 is arranged at the center position of the wheel hub 110, and the elastic tire 120 is arranged around the outer periphery of the wheel hub 110 to support the wheel hub 110. The vehicle tire 100 usually has a wheel hub 110 and an elastic tire 120. Generally, the outer surface of the wheel hub 110 of the vehicle tire 100 (such as a car tire) is concave. If the wire-laying bracket 200 is directly arranged on the concave wheel hub 110, the concave wheel hub 110 will convex downward, so that the middle position of the tire will abut against the ground and lift the tire, which will cause the vehicle tire 100 to be placed unevenly on the ground. In this embodiment, the wheel hub 110 is reversed, so that the convex surface of the wheel hub 110 is upward, so that the upper surface of the wheel hub 110 is upwardly convex toward the center position, so that the lower surface of the profile is upwardly concave. The outer elastic tire 120 contacts the ground while the wheel hub 110 is kept away from the air, thereby reducing the shaking caused by uneven ground.

[0040] See also Figure 1 In this embodiment, the elastic tire 120 contacts the ground, and the elasticity of the elastic tire 120 is used to achieve flexible landing, which is more stable and reduces friction. During use, the pressure of the steel coil is elastically buffered, making it smoother to use.

[0041] During the modification of the mining cart, the bearing member (bearing chamber) located at the center of the wheel hub 110 needs to be reversed, which can lower the center of gravity and avoid the unstable center of gravity of the wire-laying support 200 when carrying the steel bar coil.

[0042] See also Figure 1Furthermore, the wire-laying support 200 in this embodiment specifically includes: a column 210, a support base frame 220 and a winding frame 230. The column 210 is vertically arranged on the bearing member 130 and is rotatably connected to the wheel hub 110 through the bearing member 130. The column 210 can also directly use the wheel axle of a waste mining cart, and the wheel axle itself can achieve a relatively good assembly match with the bearing member 130 without additional processing. By using local materials, the production cost can be reduced. The support base frame 220 surrounds the column 210 and is fixedly connected to the column 210. The winding frame 230 is fixedly connected to the support base frame 220 and is used to place the steel bar coil. The support base frame 220 and the winding frame 230 form a stable support structure. When the steel bar coil is sleeved on the winding frame 230, the steel bar coil can be supported by the support base frame 220, so that the steel bar coil can be placed more stably on the wire-laying support 200 to achieve stable wire laying.

[0043] See also Figure 1 Furthermore, the diameter of the outer circle formed by the winding frame 230 in this embodiment gradually increases from top to bottom. The outer circle formed by the winding frame 230 refers to the outer circle path formed by the rotation path during the rotation of the winding frame 230. In this way, the outer contour of the winding frame 230 forms a conical structure. The winding frame 230 with a conical structure can realize automatic centering of the steel coil, so that the steel coil can avoid weightlessness and swaying.

[0044] See also Figure 1 Furthermore, the winding frame 230 in this embodiment specifically includes a plurality of support rods 231, which are distributed in a circle around the column 210, and each support rod 231 gradually moves away from the column 210 from top to bottom. The structure using a plurality of support rods 231 can be directly welded and fixed on the column 210, which is convenient for processing. Moreover, the winding frame 230 formed by surrounding the support rods 231 can reduce the weight of the entire winding frame 230 and reduce the load of the bearing member.

[0045] Furthermore, the support rod 231 in this embodiment specifically includes: an upper inclined rod 232 and a lower inclined rod 233, one end of the upper inclined rod 232 is fixedly connected to the column 210, and the other end extends obliquely in a direction away from the column 210; one end of the lower inclined rod 233 is fixedly connected to the upper inclined rod 232, and the other end extends obliquely in a direction away from the column 210 and is connected to the support frame 220; the slope of the upper inclined rod 232 is smaller than the slope of the lower inclined rod 233. The outer contour of the conical structure surrounded by the upper inclined rod 232 has a small inclination angle, and the outer contour of the conical structure surrounded by the lower inclined rod 233 has a large inclination angle, which can ensure the stability of the structure, so that the entire support rod 231 is subjected to more reasonable force in the process of supporting the steel bar coil, and the use of the inclined upper inclined rod 232 makes it easier for the steel bar coil to be inserted into the winding frame 230.

[0046] See also Figure 1 , Figure 3 Furthermore, in another structure, a horizontal connecting rod 234 can be welded at the connection between the upper inclined rod 232 and the lower inclined rod 233, one end of the horizontal connecting rod 234 is welded and fixed to the connection between the upper inclined rod 232 and the lower inclined rod 233, and the other end is welded and fixed to the column 210. The horizontal connecting rod 234 can support the support rod 231, improve the support strength of the support rod 231, make the structure more stable, and can bear more weight, thereby ensuring stability in the process of bearing the steel bar coil.

[0047] See also Figure 1 Further, the support base frame 220 in this embodiment specifically includes: an outer ring 221 and a plurality of support bottom rods 222. The outer ring 221 is arranged around the column 210, and the plurality of support bottom rods 222 are located in the outer ring 221. The two ends of each support bottom rod 222 are respectively welded and fixedly connected to the column 210 and the outer ring 221. By welding and fixing the support bottom rod 222 and the outer ring 221 to the central column 210, the weight of the support base frame 220 can be effectively reduced, and the load-bearing burden of the bearing member can be reduced.

[0048] See also Figure 1 Furthermore, the outer diameter of the vehicle tire 100 in this embodiment is smaller than the outer diameter of the outer ring 221. The outer diameter of the outer ring 221 is set larger to determine a larger rotation area during the rotation process. If the steel coil is supported by the support frame 220, a steel coil with a larger diameter can be carried, so that the unwinder can unwind a steel coil with a larger coil diameter.

[0049] See also Figure 1 , Figure 2 Further, in another structure, a plurality of auxiliary support members 240 are provided at the bottom of the wire-laying support 200, and the plurality of auxiliary support members 240 are distributed around the rotation center of the wire-laying support 200, and the plurality of auxiliary support members 240 abut against and move on the upper surface of the vehicle tire 100. The entire wire-laying support 200 is supported by the plurality of auxiliary support members 240, and when the steel bar coil carried by the wire-laying support 200 is heavy, the auxiliary support members 240 can share the pressure on the middle bearing member, thereby reducing the force on the bearing member and preventing the bearing member from being overloaded and crushed.

[0050] See also Figure 2Furthermore, the auxiliary support member 240 in this embodiment specifically includes: a rolling bracket 241 and a roller 242. The rolling bracket 241 is fixedly arranged at the bottom of the wire-laying bracket 200, and the roller 242 is rotatably arranged on the rolling bracket 241 and abuts against the upper surface of the vehicle tire 100. The roller 242 is installed by the rolling bracket 241, and when the wire-laying bracket 200 rotates, the roller 242 rolls on the upper surface of the vehicle tire 100, and the gravity of the middle bearing member can be shared by the roller 242 and the rolling bracket 241.

[0051] See also Figure 2 In the specific structure, the rolling bracket 241 is fixed to the lower surface of the supporting bottom rod 222, and the roller 242 is against the upper surface of the outer edge of the wheel hub 110. The plane of the upper surface of the outer edge of the wheel hub 110 allows the roller 242 to roll smoothly. The outer ring of the roller 242 is rubber, which can produce a little elastic deformation after being stressed, so as to ensure the rolling stability.

[0052] Furthermore, in another structure (not shown in the figure), a bracket can be added to the vehicle tire 100, and a motor and a reducer can be installed on the bracket. The motor drives the column 210, thereby realizing automatic rotation of the wire-releasing bracket 200.

[0053] In summary, the rebar coil unwinder proposed in this application utilizes vehicle tires for flexible landing, is more stable when placed on the ground, reduces friction, and is smoother during the unwinding process. And by reversely installing the wheel hub of the vehicle tire so that the convex surface of the wheel hub faces upward, the shaking caused by the uneven ground is reduced, and it is more stable when placed on the ground. In addition, reversely installing the bearing chamber can lower the center of gravity of the unwinding bracket, avoiding the unstable center of gravity of the unwinding bracket when carrying the rebar coil. By making the unwinding bracket into a cone, automatic centering can be achieved after the rebar coil is put on the unwinding bracket, avoiding the weightlessness and swaying of the rebar coil during rotation.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
