Description

Technical Field

[0001] This utility model relates to the field of H-beam processing technology, specifically to a follow-up central support roller device. Background Technology

[0002] H-beam production lines are now widely used. H-beam production lines require the use of roller conveyors. The main function of rollers is to achieve the smooth conveying, positioning, or turning of materials (such as plates, boxes, etc.) through their own rotation or static support. There is an assembly process in the process. The pre-assembly process before the horizontal assembly machine is the pre-assembly process. In the H-beam production line, rollers are required to convey the web and flanges of the H-beam.

[0003] The core of existing roller conveyor devices is to convert the torque of the power system (such as motors and reducers) into the linear motion power of the material, or to form a stable conveying path through the coordinated arrangement of multiple sets of rollers. At the same time, it bears the weight of the material and reduces the frictional resistance during the conveying process, ensuring that the material flows efficiently at a set speed and direction. In the welding process of H-beams, there is an assembly process. The pre-assembly process is the process before the horizontal assembly machine. In the pre-assembly process, the web and wing plates are laid flat on the rollers, which makes the rollers longer. If the length is too long, it will cause the middle part to deform and sag, which may lead to uneven local stress on the workpiece, resulting in deviation and serpentine phenomena. Therefore, it is necessary to add support in the middle part of the roller to reduce the deformation and sagging in the middle part of the roller. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing idler roller devices are prone to deformation under stress during use, which leads to uneven local stress on the workpiece, resulting in deviation and serpentine phenomena, thereby affecting the stability of the conveying.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A follow-up central support roller device includes a crossbeam, a roller wheel rotatably connected to the crossbeam, a mounting base installed on the crossbeam, two support rollers rotatably connected to the mounting base, the support rollers being supported at the bottom end of the roller wheel, two support wheel shafts installed on the mounting base, deep groove ball bearings coaxially installed on each support roller, the deep groove ball bearings being rotatably connected to the support wheel shafts in sequence, a cover installed at the end of the support wheel shaft, a pressure cap installed on the support roller, a plurality of first bolts threadedly connected to the pressure cap, and a second bolt threadedly connected between the cover and the support wheel shaft.

[0006] The beneficial effects of this utility model are as follows: by providing an mounting base, supporting rollers, supporting wheel axles, a pressure cap, a first bolt, a stop cover, a second bolt, and a deep groove ball bearing, the stability of the installation of the supporting rollers and the deep groove ball bearing is improved by the cooperation of the pressure cap and the first bolt. The deep groove ball bearing reduces the resistance to the rotation of the two supporting rollers, allowing the supporting rollers to rotate and be supported at the bottom of the idler roller. The supporting rollers can rotate with the idler roller to avoid sagging deformation in the middle of the idler roller, thereby improving the stability of the idler roller device.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the mounting base has a groove for the idler roller to rotate, which improves the ease of rotation of the idler roller.

[0009] Furthermore, a first rib is fixedly connected to the mounting base, and the first rib and the mounting base are fixedly connected to form an integral structure. Several first threaded grooves are opened on the mounting base, which improves the stability of the mounting base installation.

[0010] Furthermore, two limiting seats are fixedly connected to the top of the crossbeam. The limiting seats allow the two ends of the idler roller to rotate, and a synchronous wheel is fixedly connected to one end of the idler roller through the limiting seat.

[0011] Furthermore, both ends of the crossbeam are fixedly connected to a first support leg, and the middle of the crossbeam is fixedly connected to a second support leg, which improves the stability of the bottom support of the crossbeam.

[0012] Furthermore, the bottom end of the first support leg is fixedly connected to a first base, and the bottom end of the second support leg is fixedly connected to a second base. Threaded holes are provided on the surfaces of both the first base and the second base.

[0013] Furthermore, second ribs are fixedly connected to the inner sidewalls of the crossbeams near the mounting base. The second ribs and the crossbeams are fixedly connected to form an integral structure, which improves the overall stability of the crossbeams.

[0014] Furthermore, the gland is annular, the cover is convex, and both the cover and the second rib are supported on the sidewall of the deep groove ball bearing.

[0015] The beneficial effects of adopting the above-mentioned further solution are: by providing a first threaded groove, a first rib, and a groove, with the groove opened on the mounting base for the idler roller to rotate, and the first rib fixedly connected to the mounting base to form an integral structure, the overall stability of the mounting base is improved.

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0020] like Figure 1-5As shown, a follow-up central support roller device includes a crossbeam 1, which is a channel steel used for support and limitation. A roller 2 is rotatably connected to the crossbeam 1. The roller 2 supports the web and flanges of an H-beam. The roller 2 typically uses multiple sets of linearly arranged H-beam webs and flanges to linearly move to a designated position for processing. A mounting base 3 is bolted to the crossbeam 1. Two support rollers 4 are rotatably connected to the mounting base 3. The support rollers 4 are both supported at the bottom of the roller 2 and can rotate with the roller 2. The two support rollers 4 provide support and limitation, thereby avoiding... The idler roller 2 has a drooping deformation in the middle. Two support roller shafts 8 are bolted to the mounting base 3. The two support roller shafts 8 are symmetrically distributed. Each support roller 4 has two deep groove ball bearings 16 coaxially mounted. The four deep groove ball bearings 16 are model 6205. The deep groove ball bearings 16 are rotatably connected to the support roller shafts 8. The rotation of the balls inside the deep groove ball bearings 16 reduces the resistance between the two support rollers 4 and the support roller shafts 8, thereby improving the stability of the support rollers 4 supporting the bottom of the idler roller 2 and reducing interference with the rotation of the idler roller 2. A cover 14 is installed at the end of the support wheel axle 8, and a pressure cap 12 is installed on the support roller 4. Several first bolts 13 are threaded onto the pressure cap 12. The first bolts 13 can be M4×12 hex socket head caps. The first bolts 13 are used to connect the support roller 4 and the first bolts 13. A second bolt 15 is threaded between the cover 14 and the support wheel axle 8. The second bolt 15 can be M8×25 hex socket head caps. The pressure cap 12 is annular, and the cover 14 is convex. Both the pressure cap 12 and the cover 14 are made of Q235 steel. The cover 14 and the second rib 17 are both supported in a deep trench. On the side wall of the ball bearing 16, the cover 14 is rotatably connected to the middle of the pressure cover 12. By setting the mounting base 3, support roller 4, support wheel shaft 8, pressure cover 12, first bolt 13, cover 14, second bolt 15 and deep groove ball bearing 16, the stability of the installation of support roller 4 and deep groove ball bearing 16 is improved by the cooperation of pressure cover 12 and first bolt 13. The deep groove ball bearing 16 reduces the resistance of the rotation of the two support rollers 4, so that the support rollers 4 are rotated and supported at the bottom of the idler roller 2 to avoid the middle of the idler roller 2 from sagging and deformation, thereby improving the stability of the idler roller device.

[0021] like Figure 1-4 As shown, the mounting base 3 has a groove 11 for the idler roller 2 to rotate, which improves the convenience of the idler roller 2 to rotate. A first rib 10 is fixedly connected to the mounting base 3. The first rib 10 and the mounting base 3 are fixedly connected to form an integral structure. The mounting base 3 has several first threaded grooves 9, which improves the stability of the mounting base 3. By setting the first threaded grooves 9, the first rib 10 and the groove 11, the groove 11 is opened on the mounting base 3 for the idler roller 2 to rotate, and the first rib 10 is fixedly connected to the mounting base 3 to form an integral structure, the overall stability of the mounting base 3 is improved.

[0022] like Figure 1 As shown, two limiting seats 5 are fixedly connected to the top of the crossbeam 1. The limiting seats 5 allow the two ends of the idler roller 2 to rotate. One end of the idler roller 2 passes through the limiting seat 5 and is fixedly connected to the synchronous wheel 6 through the coupling. The synchronous wheel 6 can cooperate with the synchronous belt. The synchronous belt drives the synchronous wheel 6 to rotate, thereby causing several idler rollers 2 to rotate, thus realizing material conveying.

[0023] like Figure 5 As shown, both ends of the crossbeam 1 are fixedly connected to the first support leg 7, and the middle of the crossbeam 1 is fixedly connected to the second support leg 18, which improves the stability of the bottom support of the crossbeam 1. The bottom of the first support leg 7 is fixedly connected to the first base 19, and the bottom of the second support leg 18 is fixedly connected to the second base 20. The surfaces of the first base 19 and the second base 20 are both provided with threaded holes. The inner side wall of the crossbeam 1 near the mounting base 3 is fixedly connected to the second rib plate 17. The second rib plate 17 and the crossbeam 1 are fixedly connected to form an integral structure, which improves the overall stability of the crossbeam 1.

[0024] Working principle: When using this follow-up central support roller device, the operator first installs the mounting base 3 on the crossbeam 1 with bolts, so that the two rollers are rotatably connected to the bottom end of the roller 2. The support roller shaft 8, pressure cover 12, stop cover 14 and deep groove ball bearing 16 cooperate to improve the stability of the support roller 4 installation. The rotation of the deep groove ball bearing 16 reduces the resistance of the support roller 4 rotatably connected to the support roller shaft 8. The roller 2 and the support roller 4 transmit force through friction, so that the support roller 4 can follow the rotation of the roller 2. The support roller 4 is supported at the bottom end of the roller 2 to avoid the middle of the roller 2 from sagging and deformation, thereby improving the conveying stability of the roller device. The first rib plate 10 and the first threaded groove 9 are fixedly connected to form an integral structure. The first threaded groove 9 is opened on the mounting base 3 for bolt installation, which improves the overall stability of the mounting base 3.

[0025] Secondly, the second rib plate 17 and the crossbeam 1 are fixedly connected to form an integral structure, which improves the overall stability of the crossbeam 1. The second support leg 18 is fixedly connected to the bottom end of the crossbeam 1, thereby preventing the crossbeam 1 from bending downwards and thus improving the stability of the crossbeam 1 supporting the mounting base 3.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
