Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery and equipment technology, specifically to a non-circular guide rail device that can be applied to a steel hook machine. Background Technology

[0002] Currently, the transfer of billets produced by continuous casting machines in steel plants is typically carried out using a hook-lifting machine. Because the billets produced by continuous casting machines include both square and round billets, and the weight per meter of steel varies, the weight of the billets hooked by the hook-lifting machine cannot be evenly distributed on the standard light rails of the two track beams during the transfer process. This results in severe wear on the rail head treads of the standard light rails on the track beams. Furthermore, the standard light rails are made of I-beam steel rails with relatively weak load-bearing capacity (such as...). Figure 1 As shown in the diagram, in more severe cases, the rail web support surface of the standard light rail will be crushed, and the gears and racks used for the transmission of the hooking machine will be compressed. Consequently, the traveling wheels on the hooking machine will not be able to contact the rail head tread and will spin freely, which will seriously affect the rotation of the traveling wheels of the hooking machine, causing the encoder to count inaccurately, the positioning to fail, and other derivative accidents to occur, affecting normal production operations. Utility Model Content

[0003] The purpose of this invention is to provide a non-circular guide rail device that can be applied to hook steel machines, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a non-circular guide rail device applicable to a steel hook machine, wherein several traveling wheels are installed on both sides of the steel hook machine, and the steel hook machine can move on the non-circular guide rail device through the traveling wheels. The non-circular guide rail device is installed on a track beam, and the non-circular guide rail device includes a non-circular guide rail and a right-angle pressure plate. The non-circular guide rail includes multiple sections extending along a first direction and connected end-to-end. The ends of the first non-circular guide rails respectively form a first end face and a second end face that can fit together. The first end face of the first non-circular guide rail is connected to the adjacent end face of the other non-circular guide rail. The second end faces of a first irregularly shaped guide rail abut against each other. The first irregularly shaped guide rail includes a horizontal plate portion and a vertical plate portion that is vertically fixed to the horizontal plate portion. The vertical plate portion extends from both ends of the horizontal plate portion. Along the second direction, the width of the vertical plate portion is equal everywhere. The top surface of the vertical plate portion is formed as a track tread surface, and the track tread surface is adapted to the traveling wheel. The second direction is perpendicular to the first direction and perpendicular to the top surface of the track beam. Right-angle pressure plates are respectively pressed onto both ends of the horizontal plate portion to fix the irregularly shaped guide rail to the track beam. Furthermore, along the second direction, the top surface of the right-angle pressure plate is lower than the track tread surface of the irregularly shaped guide rail.

[0005] Based on the above technical features, this utility model uses inverted T-shaped steel rails with stronger load-bearing capacity to replace standard I-beam light rails. This effectively solves the problem of I-beam steel rails being easily crushed at the web in existing technologies. It not only provides a continuous and smooth rolling surface but also withstands the high pressure generated by equipment imbalance caused by uneven weight of the cast billets hooked by the steel hooking machine, resulting in a longer service life than I-beam steel rails. Furthermore, the irregular-shaped guide rail uses multiple sections of the first irregular-shaped guide rail connected end-to-end. When the tread surface of a certain section of the first irregular-shaped guide rail shows severe wear, it can be disassembled and replaced individually, significantly reducing production costs compared to replacing the entire I-beam steel rail.

[0006] In this preferred embodiment, the inner surface of the right-angle pressure plate that abuts against the horizontal plate is stepped, the stepped surface is adapted to the outer surface of the horizontal plate that is in contact with it, and the stepped surface faces the top surface of the track beam; more preferably, the included angle of the stepped surface of the right-angle pressure plate is 90°.

[0007] Based on the above technical features, the track pressure plate used for fixing and installing irregularly shaped guide rails is selected as a right-angle pressure plate with better fixing effect, so that it can more reliably press and fix the irregularly shaped guide rails and provide stable support for them; at the same time, the step surface of the right-angle pressure plate has a right-angle shape, so that the right-angle pressure plate can better adapt to the irregularly shaped guide rails and ensure the stability of the installation and fixing of the irregularly shaped guide rails.

[0008] In this preferred embodiment, the right-angle pressure plate is fixed to the track beam by bolts, and the top of the mounting bolt does not protrude from the top surface of the right-angle pressure plate; more preferably, the bolt is an internal hex bolt, and the top surface of the right-angle pressure plate forms a bolt mounting hole adapted to the bolt. The bolt mounting hole includes a screw hole section and a straight hole section, and a stepped surface is formed at the connection between the screw hole section and the straight hole section. The stepped surface faces away from the track beam.

[0009] Based on the above technical features, hexagon socket head cap screws are selected, and the nuts of the screws can be recessed into the inside of the right-angle pressure plate, so that the top of the screw does not protrude from the top surface of the right-angle pressure plate, effectively avoiding interference between the wheels and the screws.

[0010] In a preferred embodiment of this technical solution, the irregular-shaped guide rail further includes a second irregular-shaped guide rail and a third irregular-shaped guide rail. The second and third irregular-shaped guide rails are respectively connected to the two ends of a plurality of first irregular-shaped guide rails connected end to end. The end of the second irregular-shaped guide rail facing the first irregular-shaped guide rail forms a third end face, which matches the first end face of the first irregular-shaped guide rail. The end of the third irregular-shaped guide rail facing the first irregular-shaped guide rail forms a fourth end face, which matches the second end face of the first irregular-shaped guide rail. More preferably, the first, second, third, and fourth end faces are all smooth inclined surfaces with the same included angle, and the included angle of the smooth inclined surface is 30° to 60°. In one embodiment of this utility model, the included angle of the smooth inclined surface is 45°.

[0011] Based on the above technical features, the front and rear ends of two adjacent irregular guide rails form inclined surfaces with a certain angle between them. The adjacent irregular guide rails are fixedly installed in an alternating manner, which effectively avoids the problem of "rail biting" at the joint of the irregular guide rail during the travel of the wheels, thus improving the stability of operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that in the description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0025] like Figures 1 to 8 As shown, this utility model provides a technical solution: a special-shaped guide rail device that can be applied to a hook steel machine. Several walking wheels 11 are installed on both sides of the hook steel machine 1. The hook steel machine 1 can achieve walking motion on the special-shaped guide rail device 12 through the transmission of gears and racks 13 via the walking wheels 11. The special-shaped guide rail device 12 is installed on the track beam 3. The special-shaped guide rail device 12 includes a special-shaped guide rail 2 and a right-angle pressure plate 4.

[0026] The irregular guide rail 2 is composed of multiple first irregular guide rails 21, a second irregular guide rail 22, and a third irregular guide rail 23. The multiple first irregular guide rails 21 extend along a first direction and are connected end to end in sequence. The second irregular guide rail 22 and the third irregular guide rail 23 are respectively installed at both ends of the multiple first irregular guide rails 21 connected end to end. The ends of the first irregular guide rails 21 respectively form a first end face and a second end face that can fit together. The first end face of the first irregular guide rail 21 abuts against the second end face of the adjacent first irregular guide rail 21. The end of the second irregular guide rail 22 facing the first irregular guide rail 21 forms a third end face, which fits together with the first end face of the opposite first irregular guide rail 21. The end of the third irregular guide rail 23 facing the first irregular guide rail 21 forms a fourth end face, which fits together with the second end face of the opposite first irregular guide rail 21. Preferably, when installing the irregular guide rail 2 on the track beam 3, the horizontal height between each section of the irregular guide rail 2 must be measured to ensure the levelness and the stability of the hook steel machine 1 when it moves.

[0027] Specifically, in the irregular guide rail device 12 introduced in this utility model, when the track tread of a certain section of the first irregular guide rail 21, the track tread of the second irregular guide rail 22, and the track tread of the third irregular guide rail 23 are severely worn, causing the traveling wheel 11 to be unable to travel normally, the worn section of the first irregular guide rail 21, the second irregular guide rail 22, or the third irregular guide rail 23 can be disassembled and replaced individually. Compared with the prior art of replacing the entire section of the I-beam rail, this method facilitates the maintenance of standard light rails and can also greatly reduce production costs.

[0028] Furthermore, such as Figure 4 As shown, the first irregular-shaped guide rail 21 includes a horizontal plate portion 211 and a vertical plate portion 212 vertically fixed to the horizontal plate portion 211. The vertical plate portion 212 extends from both ends of the horizontal plate portion 211. Along the second direction (i.e., the vertical direction), the width of the vertical plate portion 212 is equal everywhere. The top surface of the vertical plate portion 212 is formed as a track tread, and the track tread is adapted to the traveling wheel 11. The second direction is perpendicular to the first direction and perpendicular to the top surface of the track beam 3. Preferably, the second irregular-shaped guide rail 22 and the third irregular-shaped guide rail 23 are both composed of the horizontal plate portion 211 and the vertical plate portion 212, and the horizontal plate portion 211 and the vertical plate portion 212 are integrally connected to form the first irregular-shaped guide rail 21, the second irregular-shaped guide rail 22, or the third irregular-shaped guide rail 23. In this utility model, the irregular guide rail 2 uses an inverted T-shaped steel rail with stronger load-bearing capacity to replace the standard I-shaped light rail in the prior art, which effectively solves the problem that the I-shaped steel rail is easily crushed at the web. The inverted T-shaped steel rail can not only provide a continuous and smooth rolling surface, but also withstand the large pressure caused by the uneven weight of the billet 6 hooked by the hooking machine 1, which causes the equipment to be unbalanced. Its service life is longer than that of the I-shaped steel rail.

[0029] like Figures 5 to 7 As shown, the first and second end faces of the first irregular-shaped guide rail 21, the third end face of the second irregular-shaped guide rail 11, and the fourth end face of the third irregular-shaped guide rail 23 are all smooth inclined surfaces with the same included angle, which is 30° to 60°. Preferably, in this embodiment of the invention, the included angle of the smooth inclined surface is 45°. The front and rear ends of two adjacent irregular-shaped guide rails 2 form inclined surfaces with a certain included angle to each other. The adjacent irregular-shaped guide rails 2 are staggered and fixedly installed, which effectively avoids the problem of "rail biting" at the joint of the irregular-shaped guide rail 2 during the movement of the traveling wheel 11, thus effectively improving the stability of operation.

[0030] like Figure 4 As shown, right-angle pressure plates 4 are respectively pressed onto both ends of the horizontal plate portion 211 to fix the irregular guide rail 2 onto the track beam 3. Furthermore, along the second direction, the top surface of the right-angle pressure plates 4 is lower than the track tread surface of the irregular guide rail 2. Preferably, to improve the hardness and wear resistance of the irregular guide rail 2, the track tread surface of the irregular guide rail 2 undergoes heat treatment processes such as tempering and surface quenching.

[0031] Furthermore, the inner surface of the right-angle pressure plate 4 that abuts against the horizontal plate portion 211 is stepped, and the stepped surface is adapted to the outer surface of the horizontal plate portion 211, with the stepped surface facing the top surface of the track beam 3. Preferably, the included angle of the stepped surface of the right-angle pressure plate 4 is 90°. In this utility model, the track pressure plate used for fixing the irregular guide rail 2 is a right-angle pressure plate 4 with better fixing effect, which can more reliably press and fix the irregular guide rail 2, providing stable support for the irregular guide rail 2; at the same time, the included angle of the stepped surface of the right-angle pressure plate 2 is a right angle shape, so that the right-angle pressure plate 4 can better adapt to the irregular guide rail 2, ensuring the stability of the installation and fixing of the irregular guide rail 2.

[0032] like Figure 4 As shown, the right-angle pressure plate 4 is fixed to the track beam 3 by bolts 5. The top of the bolts 5 does not protrude from the top surface of the right-angle pressure plate 4, preventing interference between the traveling wheel 11 and the bolts 5 during travel. Preferably, the bolts 5 are hexagon socket head cap screws. The top surface of the right-angle pressure plate 4 forms bolt mounting holes 41 that are compatible with the bolts 5. The bolt mounting holes 41 include a threaded section and a straight section. A stepped surface is formed at the connection between the threaded section and the straight section, and the stepped surface faces away from the track beam 3. The use of hexagon socket head cap screws allows the nuts of the bolts 5 to be recessed into the right-angle pressure plate 4, ensuring that the top of the bolts 5 does not protrude from the top surface of the right-angle pressure plate 4, effectively preventing interference between the traveling wheel 11 and the bolts 5.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
