Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering grid knitting devices, and specifically relates to a steel wire unwinding rack. Background Technique

[0002] When manufacturing a civil engineering grid, in order to improve the strength of the civil engineering grid, it is necessary to set a steel wire structure on the basis of the originally horizontally and vertically arranged grid bars. In order to meet the production requirements of the production equipment, the above-mentioned steel wire coil needs to be unwound by rotation. In order to make the unwinding process smoother, the existing method is to place the steel wire coil on a rotating disk. However, due to the overall structure of the steel wire coil, when the steel wire is pressed by the steel wire coil, the unwinding process is likely to be unsmooth. Content of the Utility Model

[0003] In order to solve the problem that the steel wire unwinding process is easily pressed by the whole steel wire coil and affects unwinding, the utility model provides a steel wire unwinding rack.

[0004] The technical solution of the utility model is as follows:

[0005] A steel wire unwinding rack includes a lifting frame. Above the lifting frame, there is a vertical rotating shaft that can rotate in a horizontal plane. A horizontally arranged support collar is sleeved outside the vertical rotating shaft, and the vertical rotating shaft is connected to the support collar through a plurality of connecting rods circumferentially arranged around the rotation axis;

[0006] At the top of the vertical rotating shaft, a plurality of support rods are circumferentially arranged around the rotation axis, and the other ends of the support rods are fixed to the connecting rods;

[0007] The height difference value between the upper and lower ends of the support rod is greater than the distance length value between the lower end of the support rod and the vertical rotating shaft.

[0008] In this way, the steel wire coil can be supported by the support rod, and it can be avoided that directly placing it on the disk causes the steel wire coil to sag and press down the steel wire, affecting the unwinding process.

[0009] In order to improve the support effect, the plane where the support collar is located is higher than the end where the connecting rod is fixed to the vertical rotating shaft. The connecting rod, the support rod and the vertical rotating shaft can form a triangular support structure.

[0010] In order to be applicable to steel wire coils of different specifications, a plurality of locking holes are arranged at intervals along the length direction of the connecting rod. A bolt is arranged at the end of the support rod and passes through the locking hole to be fixed to the connecting rod. According to the inner diameter of steel wire coils of different specifications, the position of the support rod relative to the connecting rod can be appropriately adjusted, thereby avoiding the steel wire coil directly contacting the support collar.

[0011] The specific structure of the above support rod is that the support rod includes two sections, which are respectively a first inclined section and a second inclined section arranged from top to bottom.

[0012] As a preferred solution, the slope of the first inclined section is greater than that of the second inclined section.

[0013] To avoid breakage between the support rod and other structures, the connecting rod and the support rod that are connected to each other are located in the same vertical plane.

[0014] To be applicable to wire coils of different weights, 5 - 8 connecting rods and support rods are provided.

[0015] The way to fix the lifting frame is that the lifting frame is fixed to the ground through a plurality of through rods.

[0016] To unwind multiple wire coils simultaneously, the vertical rotating shaft is symmetrically arranged on the lifting frame or a plurality of them are circumferentially arranged around the center of the lifting frame.

[0017] As a preferred solution, the wire coil placed on the support rod does not contact the support collar. Generally, it is supported by the second inclined section.

[0018] The beneficial effects of the present utility model are as follows: The present utility model is a wire discharging rack, which is different from the existing rotating disc unwinding method. It rotates through the vertical rotating shaft, and then the connection between the support rod and the connecting rod is used for the support of the wire coil. And to avoid the situation where the support rod and the connecting rod rotate and misalign with low strength, the end parts of the above - mentioned structures are fixed through the support collar, thereby being able to avoid displacement of the above - mentioned structures. Moreover, the fixing positions of the support rod and the connecting rod can also be set according to the requirements of the wire coil specifications for the above - mentioned device.

[0028] like Figure 1 , 2 The wire unwinding rack shown in the figure includes a lifting frame 1, and the lifting frame 1 includes a plurality of support rods arranged in a staggered manner horizontally and vertically, and the lifting frame 1 is fixed in the manner that the lifting frame 1 is fixed to the ground through a plurality of through rods. For this purpose, a plurality of countersunk holes need to be set on the ground, and after the through rods pass through the countersunk holes, they can be prevented from moving. Since the structure itself has its own weight, the above structure will not leave the working position without the action of external force. Afterwards, a vertical rotating shaft 2 that can rotate in a horizontal plane is arranged above the lifting frame 1 to ensure that the unwinding process of the wire roll 6 is smoother, and a horizontally arranged supporting ring 5 is connected to the outer sleeve of the vertical rotating shaft 2. The position of the supporting ring 5 is close to the lower end of the vertical rotating shaft 2 and is not lower than the upper end of the lifting frame 1. Afterwards, the vertical rotating shaft 2 is connected to the supporting ring 5 through a plurality of connecting rods 3 circumferentially arranged around the rotation axis. While fixing the supporting ring 5, the connecting rod 3 can also be prevented from bending through the connection with the supporting ring 5.

[0029] Afterwards, in order to support the wire coil 6 and prevent the wire coil 6 from being pressed onto the unwinding end, a plurality of support rods 4 are circumferentially arranged around the rotation axis at the top of the vertical shaft 2, and the other ends of the support rods 4 are fixed to the connecting rods 3. Figures 2-4 As shown in FIG. 1 , a cage-like support structure is formed. At this time, the wire coil 6 can be placed on the support rod 4 from above the vertical shaft 2, and Figure 4 Generally form support.

[0030] It should be noted that in the above structure, the height difference between the upper and lower ends of the support rod 4 is greater than the distance between the lower end of the support rod 4 and the vertical shaft 2. In the above manner, the support rod 4 can be used to support the wire roll 6, which can avoid placing the wire roll 6 directly on the disc, causing the wire roll 6 to sag and then press down the wire to affect the unwinding process.

[0031] In order to be applicable to wire coils 6 of different weights, 5-8 connecting rods 3 and support rods 4 are provided. When the overall weight of the wire coil is too small, a smaller number can be provided, and the larger the cross-sectional area of the connecting rod 3 and the support rod 4, the smaller the number can be provided, otherwise, more number needs to be provided.

[0032] And, as Figure 5 shown, for any placement requirement of the wire coil 6, the wire coil 6 placed on the support rod 4 does not contact the support collar 5. And generally, there is a second inclined section 42 for support.

[0033] As a preferred embodiment, in order to improve the support effect, the plane where the support collar 5 is located is higher than the end of the connecting rod 3 fixed to the vertical rotating shaft 2. That is, as Figure 3 shown, the connecting rod 3, the support rod 4 and the vertical rotating shaft 2 can form a triangular support structure. And in order to prevent the support rod 4 from breaking with other structures, the mutually connected connecting rod 3 and the support rod 4 are located in the same vertical plane. In the top view state, that is, as Figure 1 shown in the state, this setting method has higher support strength.

[0034] Finally, as Figure 5 shown, in order to be applicable to wire coils 6 of different specifications, a plurality of locking holes 31 are arranged at intervals along the length direction of the connecting rod 3. The locking holes 31 at different positions can change the distance between the lower end of the support rod 4 and the vertical rotating shaft 2. Finally, a bolt is arranged at the end of the support rod 4 and passes through the locking hole 31 and is fixed to the connecting rod 3. According to the inner diameter of the wire coil 6 of different specifications, the position of the support rod 4 relative to the connecting rod 3 can be appropriately adjusted, so as to avoid the wire coil 6 directly contacting the support collar 5. The replacement operation is to manually separate the bolt from the support rod 4. After that, since the support rod 4 has the ability of deformation, the support rod 4 can be appropriately bent so that its end is aligned with the locking holes 31 at different positions. At this time, the bolt can pass through the locking hole 31 and be fixed to the connecting rod 3 at the corresponding position, thereby forming a support structure.

[0035] And, the specific structure of the support rod 4 is that the support rod 4 includes two sections, which are respectively a first inclined section 41 and a second inclined section 42 arranged from top to bottom. And the slope of the first inclined section 41 is greater than the slope of the second inclined section 42. If the overall slope of the support rod 4 is too gentle, it will result in a longer distance in the case of the same distance between the lower end and the vertical rotating shaft 2, and the greater the height, the more unstable it will be. Therefore, to a certain extent, the overall height of the vertical rotating shaft 2 needs to be reduced.

[0036] Finally, in order to unwind a plurality of wire coils 6 at the same time, a plurality of the vertical rotating shafts 2 are symmetrically arranged on the lifting frame 1 or circumferentially arranged around the center of the lifting frame 1. Just ensure that the structure will not tip over after the wire coil is placed.
