Technical Field

[0001] This application relates to the field of rolling steel production, and particularly to an air-cooled input roller table for a rolling steel production line. Background Art

[0002] During the rolling steel production process, the cooling and transportation of rolled steel are important links. During the rolling process of steel materials, a roller table with multiple conveyor rollers is required for transportation to facilitate the cooling of steel materials.

[0003] Currently, the existing air-cooled tracks for rolling steel usually adopt a fixed track design. For situations where the conveying height needs to be adjusted, the height is often changed by adding or reducing gaskets under the track or adjusting bolts. This method is cumbersome to operate and has a limited adjustment range. Utility Model Content

[0004] In order to improve the above problems, this application provides an air-cooled input roller table for a rolling steel production line.

[0005] The air-cooled input roller table for a rolling steel production line provided by this application adopts the following technical solutions:

A plurality of conveyor rollers are rotatably arranged on the transport roller frame. One end of the transport roller frame is hinged to the frame, and the hinge axis is parallel to the axis of the conveyor rollers. A control mechanism is provided on the frame, and the control mechanism is used to control the swing of the transport roller frame relative to the frame.

[0007] By adopting the above technical solutions, the control mechanism drives one end of the transport roller frame to lift and lower by a certain angle and maintain, achieving the purpose of adjusting the conveying height of the transport roller frame and improving the adjustment efficiency.

[0008] Preferably, the control mechanism includes an adjustment frame, a jacking rod, and a driving component. The adjustment frame is hinged to the frame, and the hinge axis is parallel to the axis of the conveyor rollers. The jacking rod is slidably connected to the adjustment frame. The end of the jacking rod is hinged to the transport roller frame, and the hinge axis is parallel to the axis of the conveyor rollers. The sliding direction is perpendicular to the hinge axis of the adjustment frame. The driving component is used to control the sliding of the jacking rod.

[0009] By adopting the above technical solutions, the movement of the jacking rod provides an up-and-down swinging force for the transport roller frame, thereby driving the change of the height of the transport roller frame.

[0010] Preferably, the driving component includes a driving source, a worm gear, and a worm. Both the worm gear and the worm are rotatably connected to the adjustment frame. The jacking rod is a lead screw, and the jacking rod is coaxially threadedly connected to the worm gear. The worm gear and the worm are meshed, and the driving source is used to control the rotation of the worm.

[0011] By adopting the above technical solution, when the worm gear rotates, the screw pair makes the jacking rod move along its own axial direction.

[0012] Preferably, the driving source is a double-shaft motor. The axis of the output shaft of the double-shaft motor is parallel to the axis of the conveying roller. There are two worm gears, worm wheels and jacking rods. The two worm gears are respectively located at both ends of the output shaft of the double-shaft motor.

[0013] By adopting the above technical solution, the two jacking rods can move synchronously, the driving assembly applies force to the transport roller frame more evenly, and the swing of the transport roller frame is more stable.

[0014] Preferably, a lifting lug block is fixedly connected to the edge of the transport roller frame.

[0016] Preferably, heat dissipation parts are formed at both ends of the conveying roller. A plurality of heat dissipation ring grooves are formed at the heat dissipation parts. The length direction of the heat dissipation ring grooves is the circumferential direction of the conveying roller.

[0017] By adopting the above technical solution, the heat dissipation ring grooves expand the surface area of the heat dissipation part with their own structure, improving the heat dissipation efficiency here.

[0018] Preferably, a protective cover is fixedly connected to the transport roller frame. The protective cover is located above the conveying roller, and the steel material is located below the protective cover.

[0019] By adopting the above technical solution, the protective cover relatively separates the rolled steel material on the transport roller frame from the outside world, reducing the probability of the steel material flying out, slipping, etc. causing harm to the staff.

[0020] Preferably, a plurality of ventilation holes are formed through the protective cover.

[0021] By adopting the above technical solution, the ventilation holes enable the air inside and outside the protective cover to communicate, which is beneficial to the heat dissipation of its internal space and the steel material, and also facilitates the staff to observe the situation inside the protective cover from the outside.

Detailed Description of the Embodiment

[0028] The following will further describe the present application in detail with reference to the attached Figure 1-2 drawings.

[0029] The embodiment of the present application discloses an air-cooled input roller table for a rolling production line. As Figure 1 shown, it includes a frame 1, a transport roller frame 2 and a control mechanism 3. A plurality of conveying rollers 21 are rotatably arranged on the transport roller frame 2. The plurality of conveying rollers 21 are arranged horizontally and uniformly in a fixed direction, and the axes of the conveying rollers 21 are parallel to each other and perpendicular to their arrangement direction. One end of the transport roller frame 2 is hinged to the frame 1, and the hinge axis is parallel to the axis of the conveying roller 21; the control mechanism 3 is used to control the swing of the transport roller frame 2 relative to the frame 1.

[0030] As Figure 1As shown in the figure, the control mechanism 3 is located on the frame 1 and at one end of the transport roller frame 2 away from the hinged position between itself and the frame 1. The control mechanism 3 includes an adjustment frame 31, a jacking rod 32, and a driving assembly 33. The adjustment frame 31 is located below the transport roller frame 2 and is hinged to the frame 1. The hinge axis is parallel to the axis of the conveyor roller 21. The jacking rod 32 is slidably connected to the adjustment frame 31. The upper end of the jacking rod 32 is hinged to the transport roller frame 2, and the hinge axis is parallel to the axis of the conveyor roller 21. The length direction of the jacking rod 32 is the same as the sliding direction and is perpendicular to the hinge axis of the adjustment frame 31. The driving assembly 33 is used to control the sliding of the jacking rod 32. When the jacking rod 32 slides, it applies a force to the transport roller frame 2 to enable it to flip. There are two jacking rods 32, and the two jacking rods 32 are respectively located at both ends of the conveyor roller 21 in the length direction. The driving assembly 33 includes a driving source 331, a worm gear, and a worm. The driving source 331 is a double-shaft motor, and the double-shaft motor is installed on the adjustment frame 31. The axis of the output shaft of the double-shaft motor is parallel to the axis of the conveyor roller 21. Both the worm gear and the worm are rotatably connected to the adjustment frame 31, and the worm gear and the worm mesh with each other to form a speed reducer 332. The jacking rod 32 is a lead screw, and the jacking rod 32 is threadedly connected to the worm gear coaxially. When the worm gear rotates, the thread pair causes the jacking rod 32 to move along its own axis. There are two worm gears and two worms, and a single worm gear and worm correspond to one jacking rod 32. The two worms are respectively coaxially fixedly connected to both ends of the output shaft of the double-shaft motor.

[0031] As Figure 1 and 2 shown in the figure, a sprocket mechanism (not shown in the figure) for driving each conveyor roller 21 to rotate is provided inside the transport roller frame. Heat dissipation parts 211 are integrally formed at both ends of each conveyor roller 21. The radial dimension of the heat dissipation part 211 is smaller than that of the transmission roller, and a plurality of heat dissipation ring grooves 212 are formed on the heat dissipation part 211. The length direction of the heat dissipation ring grooves 212 is the circumferential direction of the conveyor roller 21. The heat dissipation ring grooves 212 are used to increase the surface area of the heat dissipation part 211 and improve the heat dissipation efficiency here. A lifting lug block 22 is fixedly connected to the edge of the transport roller frame 2. During the disassembly and assembly of the transport roller frame 2, the lifting lug block 22 provides a force application point for the hoisting of the transport roller frame 2.

[0032] As Figure 1 shown in the figure, an arched protective cover 4 is fixedly connected to the transport roller frame 2. The protective cover 4 is located above the conveyor roller 21, and a space for the steel material to move through is formed below the protective cover 4. A plurality of ventilation holes 41 are formed through the protective cover 4. The ventilation holes 41 enable the air inside and outside the protective cover 4 to communicate, which is beneficial to the heat dissipation of its internal space and the steel material, and also facilitates the staff to observe the situation inside the protective cover 4 from the outside.

[0033] The implementation principle of an air-cooled input roller table for a steel rolling production line in an embodiment of the present application is as follows:

[0034] When it is necessary to change the end height position of the transport roller rack 2, the drive assembly 33 is activated to move the jacking rod 32 in the height direction, so as to drive the adjustment of the end height of the transport roller rack 2. When the drive source 331 stops running and the jacking rod 32 remains fixed, the height of the transport roller rack 2 also remains unchanged.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
