Figure 8 .

[0035] See also Figures 1 to 7 The adjusting device includes a top screw bolt 7 and a support seat 8. The support seat 8 is welded to one side of the chain beam 1. A threaded hole is machined in the support seat 8. The top screw bolt 7 passes through the threaded hole of the support seat 8 and is reciprocated along the support seat 8; a locking nut 14 is screwed on the top screw bolt 7. Two locking nuts 14 are provided and are screwed on both sides of the support seat 8 respectively; when the top screw bolt 7 is positioned, the two locking nuts 14 abut against both sides of the support seat 8 and are locked to prevent the top screw bolt 7 from moving.

[0036] One end of the top screw bolt 7 is abutted against an adjustment plate 6, and a long guide groove 9 is arranged in the adjustment plate 6. The depth direction of the guide groove 9 is perpendicular to the chain beam 1, and the length direction is parallel to the length direction of the chain beam 1; a guide bolt is slidably inserted in the guide groove 9, and the other end of the guide bolt is vertically welded to one side of the chain beam 1, and the adjustment plate 6 is limited between the nut of the guide bolt and the chain beam 1.

[0037] The guide bolts are provided in two, namely the first guide bolt 10 and the second guide bolt 5; when the top screw bolt 7 is screwed to push the adjustment plate 6 to move, the adjustment plate 6 reaches the maximum movement position after the first guide bolt 10 abuts against one end of the guide groove 9, and the first guide bolt 10 cooperates with one end of the guide groove 9 to limit the maximum sliding distance of the guide groove 9. When installing the adjustment plate 6, the other end of the guide groove 9 abuts against the second guide bolt 5 to determine the initial installation position of the adjustment plate 6.

[0038] Furthermore, the central axes of the first guide bolt 10 and the second guide bolt 5 are located in the same plane, so as to facilitate the smooth sliding of the guide groove 9 along the first guide bolt 10 and the second guide bolt 5 .

[0039] The adjusting plate 6 is fixedly connected with a track extension assembly 11, and the track extension assembly 11 moves synchronously with the adjusting plate 6. The track extension assembly 11 includes an extension plate 12 and a connecting plate 13 fixedly connected to the lower surface of the extension plate 12, and the connecting plate 13 is used to connect the extension plate 12 and the adjusting plate 6, and the top surface of the extension plate 12 is in the same height as the chain beam track 2; one end of the chain beam track 2 is provided with a receiving groove 17 along the length direction, and the receiving groove 17 is used to plug the extension plate 12.

[0040] When the adjusting plate 6 pushes the sprocket 3 to move in the logistics direction, the end of the extension plate 12 inserted into the receiving groove 17 gradually slides out of the receiving groove 17 to fill the gap between the sprocket 3 and the chain beam track 2 after the sprocket 3 moves.

[0041] A matching block 15 is fixedly connected to one side of the adjacent end of the adjusting plate 6 and the top screw bolt 7. The matching block 15 increases the abutment area between the top screw bolt 7 and the adjusting plate 6 to prevent the top screw bolt 7 from being empty due to insufficient contact area between the top screw bolt 7 and the adjusting plate 6 when the top screw bolt 7 pushes the adjusting plate 6 to slide.

[0042] The sprocket wheel 3 is rotatably connected to the connecting shaft 16 through a bearing, and a flange is provided at one end of the connecting shaft 16; a threaded hole is provided at the other end of the adjusting plate 6, and the adjusting plate 6 is fixedly connected to the flange of the connecting shaft 16 through bolts. The driving method of the sprocket wheel 3 is the existing technology and will not be described in detail here.

[0043] The following describes the use of this device:

[0044] The bar factory cooling bed outputs double-length round steel through several chain beams 1 arranged in parallel, which slide the double-length round steel from the cooling bed to the output roller. During this process, the chain will stretch and lengthen due to external force and wear. The lengthened chain will affect the cooling bed's transportation of the finished double-length round steel. The use of this device is now introduced taking a chain beam 1 as an example.

[0045] First, process the receiving groove 17 at one end of the original chain beam track 2, install the adjustment plate 6 welded with the track extension component 11 on one side of the chain beam 1, and insert one end of the extension plate 12 into the receiving groove 17; pass the first guide bolt 10 and the second guide bolt 5 through the guide groove 9 respectively and weld them at the preset welding point on one side of the chain beam 1, and initially the second guide bolt 5 abuts against one end of the guide groove 9; weld a support seat 8 on one side of the chain beam 1, and the welding position of the support seat 8 is 1 / 2 the length of the top screw bolt 7 away from one end of the adjustment plate 6; screw a locking nut 14 on the top screw bolt 7, then screw it through the support seat 8, and then screw another locking nut 14 onto the top screw bolt 7; when the top screw bolt 7 is positioned, the two locking nuts 14 are tightened on both sides of the support seat 8 to prevent the top screw bolt 7 from moving or even falling off due to vibration; install a sprocket 3 at one end of the adjustment plate 6; complete the assembly of the device and the chain beam 1.

[0046] When the chain 4 is stretched and loosened, first screw the locking nut 14 on the operating side of the top screw bolt 7 away from the support seat 8 to reserve rotation space for the top screw bolt 7, and screw the top screw bolt 7 in the direction of the adjusting plate 6. The top screw bolt 7 pushes the adjusting plate 6 to slide, and the adjusting plate 6 drives the sprocket 3 away from the chain beam 1 so that the chain 4 is tensioned. After moving to a suitable position, the locking nut 14 is tightened again on both sides of the support seat 8; as the chain 4 is deformed and stretched, the adjusting plate 6 gradually slides in the logistics direction according to the tensioning demand of the chain 4. When the first guide bolt 10 abuts against the other end of the guide groove, the adjusting plate 6 can no longer slide in the logistics direction. The reason for this design is that the acceptable elongation of the chain 4 is 50mm-60mm. If the elongation is too long, the various performances of the chain 4 will not meet the transportation requirements. Therefore, the sliding displacement of the adjusting plate 6 is set within the range of 50mm-60mm.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
