Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment for rail conveyor lines, in particular to a rail pressing and anti-collision device for heat treatment equipment of rail conveyor lines. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Due to reasons of precision or long service life, some parts of the rail conveyor line may experience deformation, settlement and other problems. The horizontality and linearity of some parts of the rail conveyor line may be skewed, causing the rails to move in a serpentine manner on the conveyor line. When the rails reach narrow processing devices such as coils and air jets of heat treatment equipment, collisions are likely to occur, causing equipment damage or casualties.

[0004] Due to the rail rolling process, rails, especially quenched rails, often have warped, lowered, or swung ends at their ends. Rails that warp, lower, or sway to one side are easily scratched when passing through narrow processing equipment. Although the coils and air jets of the heat treatment equipment have a certain degree of adjustability, the adjustable size is limited. Rails with severe warping cannot pass through the coils and air jets smoothly. In such cases, multiple people need to use crowbars to manually lower the rails before they can barely pass. This not only wastes the time and energy of the staff, but is also extremely irregular and prone to safety problems. Utility Model Content

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] As introduced in the background technology, in the prior art, when steel rails pass through the coils and air jet devices of narrow heat treatment equipment on the conveyor line, collisions are likely to occur, causing equipment damage or casualties. In order to solve the above technical problems, the utility model proposes a rail pressing and anti-collision device for heat treatment equipment of a steel rail conveyor line.

[0031] like Figure 1 、 Figure 2As shown, one embodiment of the utility model describes a rail pressing and anti-collision device for a heat treatment equipment of a rail conveyor line, comprising a base 12 and a frame 11. The base 12 is fixedly connected to the frame 11. Two support seats 13 are mounted on the base 12. A support roller 2 is provided between the two support seats 13. The support roller 2 can rotate freely. The support roller 2 is connected to the two support seats 13 by bearings and connecting shafts, and can also be other conventional connection methods. It is sufficient that the support roller 2 can rotate freely.

[0032] The support roller 2 is installed below the rail 1 to support the rail 1 . The width of the support roller 2 is not limited, but is preferably greater than the width of the rail 1 .

[0033] A rail waist roller 3 is provided above the support roller 2. Generally, two rail waist rollers 3 are provided and are symmetrically arranged. A certain distance is spaced between the two rail waist rollers 3 to allow the rail 1 to pass through. The two rail waist rollers 3 are spaced a certain distance from the standard rail. When the rail 1 tilts to one side, the rail 1 contacts the rail waist roller 3 on one side, and the rail waist roller 3 exerts a force on the rail 1 to prevent the rail 1 from excessive deviation.

[0034] The two rail waist rollers 3 are respectively installed on the two side walls of the frame 11, and a mounting seat 14 is fixed on the side wall. The mounting seat 14 is rotatably connected to the rail waist roller 3 through a connecting shaft. The connection between the connecting shaft and the rail waist roller 3 is the existing technology, and is preferably connected through a bearing.

[0035] A pressing roller 5 is installed above the gap 4 between the two rail waist rollers. The pressing roller 5 is used to limit the upward displacement of the rail 1.

[0036] A through hole is provided on the top wall of the frame 11, and the screw rod 9 is rotatably connected to the top wall of the frame 11 through the through hole. The lower end of the screw rod 9 is connected to a C-shaped bracket 7, and the screw rod 9 is rotatably connected to the C-shaped bracket 7. The connection method here is the existing technology, and is preferably connected through a bearing.

[0037] A lower pressure roller fixing block 6 is provided inside the C-shaped bracket 7. The C-shaped bracket 7 includes a top surface and a side surface. Two through holes are symmetrically provided on both sides of the spiral rod 9 on the top surface. Two through holes are also provided at corresponding positions of the lower pressure roller fixing block 6. The guide rod 8 passes through the two corresponding through holes above and below. A spring 15 is sleeved on the guide rod 8. The upper end of the guide rod 8 is fixedly connected to the C-shaped bracket, and the lower end is slidably connected to the lower pressure roller fixing block 6.

[0038] The lower ends of the two side surfaces of the C-shaped bracket are provided with inward extension portions 71, and the lower pressure roller fixing block 6 is provided with a step structure. The step structure of the lower pressure roller fixing block 6 rests on the extension portion 71 of the C-shaped bracket to prevent the lower pressure roller fixing block 6 from falling out of the C-shaped bracket.

[0039] A groove is provided on the lower side of the lower pressing roller fixing block 6, and the groove accommodates the lower pressing roller 5. The lower pressing roller is rotatably connected to the lower pressing roller fixing block 6. The connection method is the existing technology, and is preferably connected through a bearing and a connecting shaft.

[0040] The two side surfaces of the C-shaped bracket are connected to the frame 11 through a slide groove 10. The side walls on both sides of the frame 11 are provided with a slide groove 10 at the position corresponding to the C-shaped bracket. The side surface of the C-shaped bracket 7 is provided with a structure matching the slide groove 10. The C-shaped bracket 7 can slide up and down with the frame 11.

[0041] The top end of the screw rod 9 is also connected to a reducer and a motor 16 , and the motor 16 drives the screw rod 9 to move up and down.

[0042] The working principle of the anti-collision device of the utility model is:

[0043] When the end of the rail 1 reaches the anti-collision device, the relatively standard, slightly deformed rail 1 passes through the gap 4 between the lower pressure roller 5, the rail waist roller 3 and the support roller 2 and is transported forward to the heat treatment device. If the rail 1 is deformed to one side, the rail waist rollers 3 on both sides adjust the position of the rail end of the rail 1 by squeezing, so that the rail end moves toward the middle and enters the heat treatment device. If the rail 1 tilts upward, it pushes the lower pressure roller 5 to move upward, and the spring 15 is compressed to generate a downward elastic force, which applies downward pressure to the rail end through the lower pressure roller 5, so that the rail end moves downward and enters the heat treatment device. If the rail 1 tilts upward severely, the screw rod 9 is driven downward by the motor to increase the downward pressure on the rail end, so that the rail 1 enters the heat treatment device.

[0044] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
