Description

Technical Field

[0001] The utility model relates to the field of cold rolling raw material conveying equipment, and more specifically, to an improved horizontal guiding structure. Background Art

[0002] At present, a traveling crane is used in the transportation and transfer process of cold rolling raw materials. The main traveling wheels of the traveling crane move along a fixed track under the operation of a driving component to complete the transfer operation. However, in this case, the phenomenon of rail gnawing is serious. Therefore, horizontal guiding wheels need to be installed to reduce wear. Currently, 2 sets of horizontal guiding wheels are installed at the north and south ends of one side beam to reduce wear (as shown in the attached Figure 2 the manual). However, at this time, the inner guiding wheel body is likely to fall off after long-term operation (the reason is that dust containing iron filings easily enters the original horizontal guiding wheel, and then the bearing is blocked and damaged. If the bearing is damaged, the horizontal guiding wheel is likely to fall off the guiding wheel shaft), and the combined action of the inner and outer wheel bodies is likely to cause the traveling crane to be jammed, and in severe cases, it may not be able to operate;

[0003] In addition, the following problems also exist in the existing horizontal guiding wheels during actual use: the base of the bolt connection part between the guiding wheel bracket and the bottom of the main beam is assembled and welded by three 12-mm-thick steel plates, and then fixed by 3 bolts on each side. Due to insufficient welding surface and steel plate strength, the middle part of the base is likely to deform and sink, and the use effect of the guiding wheel bracket needs to be improved;

[0004] In summary, the layout method and installation and use effect of the horizontal guiding wheels on the traveling crane need to be further improved. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems raised in the above background art, and then an improved horizontal guiding structure is proposed.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0007] An improved horizontal guiding structure includes four axle brackets, axle caps, lock washers, horizontal wheel shafts, upper covers, horizontal guiding wheel bodies, and lower covers.

[0008] The axle brackets are integrally formed and are respectively connected to the two ends of the side girders on both sides of the walking beam to be symmetrically arranged at the four corners of the walking beam;

[0009] The axle caps are installed at one end of the axle brackets;

[0010] The lock washers are arranged inside the axle caps and are connected to one end of the horizontal wheel shafts;

[0011] The other end of the horizontal wheel shaft is connected with a horizontal guiding wheel body, and the horizontal wheel shaft is rotationally connected to the axle bracket through a bearing;

[0012] Upper covers and lower covers are respectively arranged at both ends of the horizontal guide wheel body;

[0013] The four horizontal guide wheel bodies are respectively in contact with the outer sides of the large lane rails on both sides.

[0014] Furthermore, the axle bracket includes a mounting bracket with a rectangular main body shape and several intermediate columns, and the mounting bracket and the intermediate columns are integrally formed.

[0015] Furthermore, reinforcing ribs penetrating through the upper and lower parts are arranged on the intermediate columns.

[0016] The above solution can significantly improve the service life of the axle bracket through the design of arranging reinforcing ribs penetrating through the upper and lower parts on the intermediate columns and integrally forming the axle bracket. Specifically, it can effectively reduce the probability of the axle bracket breaking from the middle and local deformation and sinking.

[0017] Furthermore, the axle bracket is made of Q355B steel.

[0018] Furthermore, the upper cover and the lower cover are respectively threadedly connected to the horizontal guide wheel body through hexagon socket head cap screws, and spring washers are arranged on the hexagon socket head cap screws.

[0019] The above solution enables the quick installation of the upper cover and the lower cover onto the horizontal guide wheel body through hexagon socket head cap screws and is not easy to loosen after installation.

[0020] Furthermore, sealing rings are respectively arranged on the inner sides of the upper cover and the lower cover.

[0021] The above solution can further improve the sealing effect after the upper cover and the lower cover are installed through the sealing rings, thereby further reducing the probability of dust containing iron filings in the outside world entering the inside of the horizontal guide wheel body.

[0022] Furthermore, the shaft cover is installed on the axle bracket through full-thread screws, and spring washers are arranged on the full-thread screws.

[0023] The above solution enables the quick and high-strength installation of the shaft cover onto the axle bracket through full-thread screws and is not easy to loosen after installation.

[0024] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0025] Compared with the prior art, through the layout method of the horizontal guide wheels in this application, the stress intensity of the horizontal guide wheel body during deviation correction can be effectively reduced, thereby prolonging the service life of the horizontal guide wheel body. At the same time, the support strength and stability of the axle bracket during the process of the traveling crane transporting cold-rolled materials can be improved, thereby prolonging the service life of the axle bracket. Finally, the use effect of the traveling crane is better, effectively reducing the phenomenon of rail gnawing and preventing the situation that the traveling crane jams and cannot operate.

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the accompanying drawings and embodiments:

[0032] As Figure 1 and Figure 2 shown, an improved horizontal guiding structure includes four axle brackets 1 (the axle brackets 1 are made of Q355B steel to improve strength), an axle cover 2, a locking piece 3, a horizontal wheel axle 4, an upper cover 5, a horizontal guide wheel body 6, and a lower cover 7.

[0033] The axle brackets 1 are integrally formed and are respectively connected to the two ends of the side girders on both sides of the walking beam to be symmetrically arranged at the four corners of the walking beam;

[0034] The axle cover 2 is installed at one end of the axle bracket 1 (specifically, the axle cover 2 is installed on the axle bracket 1 by a full-thread screw, and a spring washer is provided on the full-thread screw, and the full-thread screw is not labeled in the figure);

[0035] The locking piece 3 is arranged inside the axle cover 2 and is connected to one end of the horizontal wheel axle 4;

[0036] The other end of the horizontal wheel axle 4 is connected to a horizontal guide wheel body 6 (the horizontal guide wheel body 6 belongs to the prior art and its internal structural composition is not described and is not labeled in the figure), and the horizontal wheel axle 4 is rotatably connected to the axle bracket 1 through a bearing;

[0037] An upper cover 5 and a lower cover 7 are respectively provided at both ends of the horizontal guide wheel body 6 (specifically, the upper cover 5 and the lower cover 7 are respectively threadedly connected to the horizontal guide wheel body 6 by hexagon socket head screws, and the hexagon socket head screws are provided with spring washers, and the hexagon socket head screws are not numbered in the figure);

[0038] The four horizontal guide wheel bodies 6 are in contact with the outer sides of the carriageway rails on both sides respectively.

[0039] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the shaft frame 1 includes a mounting frame 11 with a rectangular main body and a plurality of intermediate columns 12, and the mounting frame 11 and the intermediate columns 12 are integrally formed.

[0040] As a further optimization of the above embodiment, the middle column 12 is provided with reinforcing ribs that pass through it from top to bottom, which are not shown in the figure. By designing reinforcing ribs that pass through it from top to bottom on the middle column 12, the probability of the middle column 12 breaking from the middle can be effectively reduced, thereby increasing the service life of the shaft frame 1.

[0041] The workflow of this utility model:

[0042] 1. First, the guide wheel bracket base, which was originally installed and welded with the main beam, was replaced with an axle bracket 1 made of a single piece of 20mm thick steel plate. The fixing bolts were upgraded from the original strength of 8.8 to 10.9, and were replaced with oblong holes, while the hole diameter and hole spacing remained unchanged.

[0043] 2. Then, the middle column was changed from the original 12mm steel plate to a 20mm steel plate, and the reinforcement ribs were changed to run through from top to bottom, and the original 8mm steel plate was changed to a 10mm steel plate; this can improve the strength of the shaft frame 1. The reinforcement ribs are not only welded on both ends of the middle column, but also in the middle, thereby reducing the probability of the shaft frame 1 breaking from the middle;

[0044] 3. Secondly, the diameter of the horizontal guide wheel body 6 is changed from the original 250mm to 300mm, and an upper cover 5 and a lower cover 7 are added at both ends of the horizontal guide wheel body 6. The upper cover 5 and the lower cover 7 are not easy to loosen, thereby preventing dust containing iron filings from the outside from entering the horizontal guide wheel body 6 and causing the probability of bearing jamming. This effectively reduces the probability of subsequent horizontal guide wheel falling off. At the same time, the bearing is changed from the original 32216 to 32218 to extend its service life;

[0045] Finally, the installation method of the horizontal guide wheel body 6 is changed from the original installation of one on each of the north and south inner and outer sides of the end beam on the driving side to installing four sets of horizontal guide wheels at the four corners of the main and secondary beams of the driving. The horizontal guide wheels only contact the outer side of the carriageway rails, thereby reducing the force intensity of the horizontal guide wheel body 6 during correction and extending its service life;

[0046] Compared with the prior art, the arrangement mode of the horizontal guide wheels in the present application can effectively reduce the stress intensity of the horizontal guide wheel body during deviation correction, thereby prolonging the service life of the horizontal guide wheel body. At the same time, it can improve the support strength and stability of the shaft bracket during the process of the traveling crane transporting cold-rolled materials, thereby prolonging the service life of the shaft bracket. Finally, the use effect of the traveling crane is better, effectively reducing the phenomenon of rail biting without causing the situation that the traveling crane jams and cannot operate.

[0047] In some embodiments, sealing rings are respectively arranged on the inner sides of the upper cover 5 and the lower cover 7, and the sealing rings are not shown in the figure. Through the sealing rings in this embodiment, the sealing effect after the upper cover 5 and the lower cover 7 are installed can be further improved, thereby further reducing the probability of external dust containing iron filings entering the inside of the horizontal guide wheel body 6.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
