Description

Technical Field

[0001] This application relates to the technical field of steel strands, specifically to a steel strand bearing frame. Background Art

[0002] A steel strand is a wire rod formed by stranding multiple steel wires, and is usually used in projects such as buildings, bridges, tunnels, and prestressed concrete components. Due to its excellent strength and toughness, steel strands are widely used in occasions that need to bear high tensile forces.

[0003] After being produced and shipped from the factory, steel strands are transported in a coiled manner. At the construction site, the coiled steel strands are supported by a bearing frame. Usually, a cross-shaped or similar shape is selected for the bearing frame to fix the steel strand coil, so as to facilitate the pulling out of the steel strands for use. Since the coiled diameter of the steel strands is large, during the process of pulling out the steel strands, the steel strands are prone to move around the outer circumference of the steel strand coil. On the one hand, it is easy to be blocked by the bearing frame and cannot be smoothly pulled out. On the other hand, the extension position of the steel strands is not easy to control, and there are certain inconveniences in on-site use. Therefore, a steel strand bearing frame is proposed to solve the above-mentioned problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, this application provides a steel strand bearing frame, which has the advantages of being able to guide the leading end of the steel strand and improving the smoothness of pulling out the leading end.

[0005] To achieve the above object, this application provides the following technical solution: A steel strand bearing frame includes a steel frame and a cross beam connecting the steel frame. A guiding structure for guiding the steel strands is movably installed between two vertically arranged cross beams on the front side;

[0006] The guiding structure includes a connecting ring and a guiding tube slidably connected between the two cross beams. A circular ring is welded on one side of the connecting ring facing the guiding tube, and a reinforcing bar for connection is welded between the outer walls of the circular ring and the guiding tube. Along platforms are integrally connected to the upper and lower ends of the connecting ring.

[0007] Further, the steel frame includes four arranged in a rectangular array, and the cross beam is connected between two adjacent steel frames. The steel frame forms a rectangular frame structure with an open top through the connection of the cross beams.

[0008] Further, a support steel is welded on the bottom end of the steel frame, and guiding rods are welded on the inner walls of the front and rear sides of the steel frame. The part of the guiding rod extending to the upper end of the steel frame is bent towards the outside of the cross beam.

[0009] Further, four reinforcing bars are distributed on the outer wall of the guiding tube, and a binding band is tied between the four reinforcing bars.

[0010] Furthermore, one side of the edge platform away from the connecting ring is a flat surface, and the other side is an arc surface that fits the connecting ring.

[0011] Furthermore, the cross beam is an I-beam with a groove recessed in the middle, and the edge platform slides along the groove of the cross beam.

[0012] Furthermore, a push rod penetrating to the outside of the edge platform is slidably installed inside the edge platform. An extrusion ball is fixedly installed at one end of the push rod facing the inside of the edge platform, and a friction pad is also fixedly installed at the top of the push rod.

[0013] Furthermore, a threaded rod for adjusting the position of the push rod is also threadedly installed on the side surface of the edge platform. The end of the threaded rod is also spherical and fits the extrusion ball, and a handle is fixedly installed at one end of the threaded rod extending to the outside of the edge platform.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] For this steel strand carrier, by adding a circular ring and a guide tube between the two cross beams of the existing carrier structure, the steel strand can surround the circular ring when being pulled out, reducing the blocked phenomenon of direct pulling out. At the same time, since the edge platform is provided to slide relative to the cross beam, the position of the guide tube can be adjusted flexibly. By setting the threaded rod and the extrusion ball to cooperate to lock the position of the edge platform, the usability of the device is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] 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.

[0021] Please refer to Figures 1 to 3 , the steel strand carrier in this embodiment includes a steel frame 1 and a cross beam 2 connecting the steel frame 1. Specifically, the steel frame 1 includes four arranged in a rectangular array, and the cross beam 2 is connected between two adjacent steel frames 1, so that the steel frame 1 forms a rectangular frame structure with an open top through the connection of the cross beam 2 for placing the steel strand coil after removing the drum.

[0022] In this embodiment, a support steel 4 is also welded on the bottom end of the steel frame 1 for supporting and lifting the steel strand coil. Guide rods 3 are welded on the inner walls of the front and rear sides of the steel frame 1. The part of the guide rod 3 extending to the upper end of the steel frame 1 is bent towards the outside of the cross beam 2 to form a wide mouth for guiding the steel strand coil to be put in.

[0023] It should be noted that a guiding structure for guiding the steel strand is also movably installed between the two vertically arranged cross beams 2 located on the front side.

[0024] In this embodiment, the guiding structure includes a connecting ring 6 and a guiding tube 9 slidably connected between the two cross beams 2. A circular ring 7 is welded on one side of the connecting ring 6 facing the guiding tube 9. A reinforcing bar 8 for connection is welded between the outer walls of the circular ring 7 and the guiding tube 9. The guiding tube 9 can be connected through the reinforcing bar 8, so that the guiding tube 9 can be installed at a suitable height position on the steel frame 1 to guide the steel strand.

[0025] Preferably, four reinforcing bars 8 are distributed on the outer wall of the guiding tube 9, and a binding belt 10 is tied between the four reinforcing bars 8. The binding belt 10 is a metal binding belt for improving the connection strength of the reinforcing bars 8.

[0026] In this embodiment, along platforms 5 are integrally connected to the upper and lower ends of the connecting ring 6. One side of the along platform 5 away from the connecting ring 6 is a plane, and the other side is an arc surface fitting the connecting ring 6. Through the connection of the along platform 5, the connecting ring 6 can slide between the two cross beams 2 to change its position.

[0027] It should be noted that the cross beam 2 is an I-beam with a groove recessed in the middle. The along platform 5 slides along the groove of the cross beam 2 to limit the connecting ring 6 and prevent the connecting ring 6 from protruding from the cross beam 2 front and back.

[0028] In order to adjust the position of the guiding tube 9, in this embodiment, a ejector rod 11 that penetrates to the outside of the edge platform 5 is slidably installed inside the edge platform 5. A pressing ball 13 is fixedly installed at one end of the ejector rod 11 facing the inside of the edge platform 5. The pressing ball 13 is a spherical metal, which is used to improve the pressure contact effect of the ejector rod 11.

[0029] In this embodiment, a threaded rod 14 for adjusting the position of the ejector rod 11 is also threadedly installed on the side surface of the edge platform 5. The end of the threaded rod 14 is also spherical and fits against the pressing ball 13. By rotating the threaded rod 14 relative to the edge platform 5, the threaded rod 14 can press the pressing ball 13, thereby forcing the ejector rod 11 to extend out of the edge platform 5.

[0030] Preferably, a friction pad 12 is also fixedly installed on the top of the ejector rod 11. The friction pad 12 improves the frictional force through contact, and is used to improve the contact locking effect between the edge platform 5 and the cross beam 2.

[0031] It should be noted that a handle 15 is also fixedly installed at one end of the threaded rod 14 extending to the outside of the edge platform 5. The outside of the handle 15 has friction stripes for facilitating the rotation of the threaded rod 14.

[0032] The working principle of the above embodiment is as follows:

[0033] By unloading the steel strand coil to a position above the steel frame 1, placing the steel strand coil between the guiding rods 3 distributed front and back and within the rectangular frame surrounded by the steel frame 1 and the cross beam 2, sliding the connecting ring 6 relative to the cross beam 2, the connecting ring 6 drives the guiding tube 9 to adjust its position relative to the cross beam 2 through the steel bar 8. Thread the end of the steel strand coil through the middle of the connecting ring 6 and through the guiding tube 9 and lead it out of the steel frame 1. By rotating the handle 15 on the outside of the edge platform 5, the handle 15 drives the fixedly connected threaded rod 14 to rotate relative to the edge platform 5, so that the end of the threaded rod 14 presses the pressing ball 13 at the lower end of the ejector rod 11, causing the ejector rod 11 to extend out of the edge platform 5 and abut against the cross beam 2, thereby restricting the position of the guiding tube 9.
