Description

Technical Field

[0001] This utility model relates to the field of transporting long, heavy, high-temperature steel billets in the steel industry, specifically a high-temperature steel billet transport platform. Background Technology

[0002] In the steel industry, situations may arise where high-temperature steel billets need to be transferred. This utility model addresses the issue of transferring steel billets between two parallel billet transport tracks. One track's heating furnace may be insufficient, necessitating the use of a furnace from the other track, thus creating a problem for transferring high-temperature steel billets. Since the billets are high-temperature, manual intervention is difficult, and the transport tracks cannot be stopped during transfer. On-site space is limited, and the transport tracks cannot be easily modified, although there is ample vertical space for modification. Because the strength and stiffness of the steel billet change after heating, making it prone to deformation, this utility model proposes a non-standard lifting hook suitable for this situation.

[0003] This utility model mainly consists of an operating system, a motion control system, and a track support system. The system has good dynamic quality and sufficient operating accuracy. Its application software is advanced, reliable, and efficient. The selected instruments, meters, controllers, and other components are of high precision, stable, and reliable. The overall structure is relatively simple, and it is convenient to use, operate, and maintain. Utility Model Content

[0004] This utility model addresses the aforementioned technical deficiencies by providing a high-temperature steel billet transfer platform.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A high-temperature steel billet transfer platform includes a motion control system, a track support system, and a transport track. The transport track is located below the track support system and includes two sets of parallel first transport tracks and second transport tracks.

[0007] Furthermore, the mobile control system is equipped with an electric hoist module. An irregularly shaped hook is connected to the electric hoist module via a self-adjusting device. The track support system includes several track supports, with the support track fixedly installed on the track supports. The electric hoist module is slidably connected to the support track. The electric hoist module includes a U-shaped support, which consists of a first vertical plate, a second vertical plate, and a horizontal plate. An electric hoist motor is fixedly installed on the outer side of the first vertical plate, and a first gear and a second gear are rotatably installed on the inner side of the first vertical plate. The output end of the electric hoist motor is connected to the first gear, and the first and second gears mesh with each other. A first rotating wheel is fixedly installed on the end face of each of the first and second gears. Two second rotating wheels are installed on the inner side of the second vertical plate. The first and second rotating wheels can rotate on the support track. When the electric hoist motor rotates, the motor output shaft drives the first gear to rotate. The first gear transmits power through meshing with the second gear, driving the first and second rotating wheels to rotate on the support track, and then driving the entire mobile control system to move.

[0008] Furthermore, a winch module is fixedly installed on the lower surface of the horizontal plate. The winch module includes a winch motor, a drum, and a support base. The winch motor drives the drum to rotate and controls the winding and unwinding of the wire rope. The winch module is fixed as a whole on the horizontal plate below the U-shaped bracket via the support base.

[0009] Furthermore, a self-adjusting device is fixedly installed below the hoisting module. The self-adjusting device includes a support tube and four adjusting springs. The wire rope on the drum passes through the support tube and is fixedly connected to the irregular hook. Four fixing rings are fixedly installed on the lower surface of the support base, and four fixing rings are also provided on the support tube. The four fixing rings on the support base and the four fixing rings between the support tubes are all spaced 90° apart. One end of the adjusting spring is connected to the fixing ring on the lower surface of the support base, and the other end is connected to the fixing ring on the support tube.

[0010] Furthermore, the first and second transport tracks have identical structures, both including a motor, coupling, base, rollers, movable baffles, gaps between plates, and cylinders. The base is fixed to the ground with bolts, the motor is installed in a designated area on the base, and the motor output shaft is connected to the rollers via a coupling. The rollers are mounted on the base via bearings. Gaps and guide grooves are provided between adjacent bases. Movable baffles are installed in the gaps between the plates, with both sides of the movable baffles engaged in the guide grooves. Cylinders are installed on the outside of the bases, and the cylinders are directly connected to the movable baffles.

[0011] A method for using a high-temperature steel billet transfer platform, characterized by the following steps:

[0012] Step 1: Install movable baffles and cylinders on the transport track at the hoisting point, and test whether the movable baffles can work normally. When working normally, the movable baffles are raised, and when not working, they are retracted into the gap between the baffles.

[0013] Step 2: Drive the movement control system by controlling the electric hoist motor. Before the billet reaches the hoisting point, it will reach the designated position. Control the winch motor to drive the irregular hook to descend and completely sink into the gap between the plates to wait for the billet to arrive. At this time, the cylinder on the first transport track will drive the movable baffle to rise.

[0014] Step 3: When the billet moves on the first transport track and reaches the hoisting point, the movable baffle stops the billet, and the control winch motor drives the special-shaped hook to rise to the position. The cylinder on the first transport track drives the movable baffle to retract into the gap between the plates. The electric hoist motor rotates and drives the mobile control system to start transferring the billet to the top of the second transport track.

[0015] Step 4: The cylinder on the second transport track drives the movable baffle to rise, and the winch motor drives the shaped hook to descend, completely sinking into the gap between the plates, placing the steel billet completely on the second transport track. The movable baffle on the second transport track retracts into the gap between the plates. After the steel billet is transported away, the winch motor drives the shaped hook to rise back to its original position.

[0016] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0017] 1. The high-temperature steel billet transfer platform and its usage method, using support modules, drive devices and transport tracks in conjunction with an electrical control system and operating software, can achieve rapid transfer of high-temperature steel billets in a safe and efficient manner.

[0018] 2. It greatly reduces manual intervention, lowers labor costs, ensures personnel safety, and minimizes the impact on the original production rhythm.

[0019] 3. The motion trajectory and working sequence are customized through the electronic control system and operating software. They can be modified according to different production rhythms and requirements. To improve production efficiency, multiple sets of drive devices can be added.

[0020] 4. To address the decrease in strength and stiffness of high-temperature steel billets and prevent bending deformation during transport, a specially shaped hook was designed to ensure the billets remain straight when passing over the curved sections of the platform's support track. A self-adjusting device is employed to reduce cable sway during hoisting.

[0021] 5. To address the issue of how to position the steel billet at the hoisting point, some transportation modules were specially modified to add movable baffles. Before hoisting, the movable baffles are raised, and after the hoisting or lowering action is completed, the movable baffles are retracted. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] like Figure 1 As shown, a high-temperature steel billet transfer platform includes a motion control system 1, a track support system 2, and a transport track 3. The transport track 3 is located below the track support system 2 and includes two sets of parallel first transport tracks 311 and second transport tracks 322.

[0035] The mobile control system 1 is equipped with an electric hoist module 11. A non-standard hook 13 is connected to the electric hoist module 11 via a self-adjusting device 12. The track support system 2 includes several track supports 22. A support track 21 is fixedly installed on the track supports 22. The electric hoist module 11 is slidably connected to the support track 21. The electric hoist module 11 includes a U-shaped support 111, which is composed of a first vertical plate 1111, a second vertical plate 1112, and a horizontal plate 1113. An electric hoist is fixedly installed on the outer side of the first vertical plate. The electric hoist motor 112 has a first gear 113 and a second gear 114 rotatably mounted on the inner side of the first upright plate 1111. The output end of the electric hoist motor 112 is connected to the first gear 113, and the first gear 113 and the second gear 114 mesh with each other. A first rotating wheel 115 is fixedly mounted on the end face of each of the first gear 113 and the second gear 114. Two second rotating wheels 116 are mounted on the inner side of the second upright plate 1112. The first rotating wheels 115 and the second rotating wheels 116 can rotate on the support rail 21. When the electric hoist motor 112 rotates, the motor output shaft drives the first gear 113 to rotate. The first gear 113 transmits power through meshing with the second gear 114, driving the first rotating wheels 115 and the second rotating wheels 116 to rotate on the support rail 21, and then driving the entire mobile control system 1 to move.

[0036] In actual production, the dimensions and shapes of the supporting rails and rail brackets are designed based on the spacing of the transport rails, the length of the straight sections of the first transport rail 311 and the second transport rail 322, the height of the factory building, and the layout of the factory building. Theoretically, the rails are straight grooves, and the rail brackets are installed at certain intervals.

[0037] A winch module is fixedly installed on the lower surface of the horizontal plate 1113. The winch module includes a winch motor 117, a drum 118 and a support base 119. The winch motor 117 drives the drum 118 to rotate and control the winding and unwinding of the wire rope. The winch module is fixed as a whole on the horizontal plate 1113 below the U-shaped bracket 111 via the support base 119.

[0038] A self-adjusting device 12 is fixedly installed below the hoisting module. The self-adjusting device 12 includes a support pipe 122 and four adjusting springs 121. The wire rope on the drum passes through the support pipe 122 and is fixedly connected to the irregular hook 13. Four fixing rings are fixedly installed on the lower surface of the support base, and four fixing rings are also provided on the support pipe 122. The four fixing rings on the support base and the four fixing rings between the support pipes are all spaced 90° apart. One end of the adjusting spring 121 is connected to the fixing ring on the lower surface of the support base, and the other end is connected to the fixing ring on the support pipe 122. The raising and lowering of the wire rope is achieved by tightening or loosening the drum. When the wire rope deviates to a certain direction, the spring force automatically adjusts the angle of the wire rope. Since the strength and stiffness of the steel billet decrease after heating, there is a risk of deformation. Therefore, the irregular hook 13 is used, which can keep the steel billet straight during the transfer of high-temperature steel billets.

[0039] The first transport track 311 and the second transport track 322 have the same structure, both including a motor 31, a coupling 32, a base 33, a roller 34, a movable baffle 35, a gap between plates 36, and a cylinder 37. The base 33 is fixed to the ground with bolts. The motor 31 is installed in a designated area on the base 33. The output shaft of the motor 31 is connected to the roller 34 through the coupling 32. The roller 34 is mounted on the base 33 through bearings. A gap between plates 36 and a guide groove are provided between two adjacent bases 33. A movable baffle 35 is installed in the gap between plates 36. The two sides of the movable baffle 35 are engaged in the guide groove. A cylinder 37 is installed on the outside of the base 33 and is directly connected to the movable baffle 35. When the motor 31 starts, it directly drives the roller 34 to rotate. The roller 34 directly contacts the lower surface of the high-temperature steel billet, driving the high-temperature steel billet forward. The base 33 has two flat plates in the middle. Rollers 34 are sandwiched between the two flat plates to fill the gap between two adjacent rollers 34, preventing the billet from falling off the track during transportation. When hoisting is required, cylinder 37 raises the movable baffle 35, which is set to a height of 140mm. During normal transportation of high-temperature billets, the movable baffle 35 is retracted, and its upper surface is parallel to the flat plate in the middle of the base 33. When preparing for transfer, the movable baffle 35 begins to rise, with its upper surface 120mm higher than the flat plate in the middle of the base 33. When fully raised, it is 20mm below the gap 36 between the plates. When the movable baffle 35 is in position, its left and right sides and lower edge are held in place by two adjacent bases 33, enhancing the overall strength. When the billet reaches the hoisting point, it will be stopped by the movable baffle 35 in position.

[0040] A method for using a high-temperature steel billet transfer platform, characterized by the following steps:

[0041] Step 1: Install a movable baffle 35 and a cylinder 37 on the transport track 3 at the hoisting point, and test whether the movable baffle 35 can work normally. When the movable baffle 35 is working normally, it rises; when not working, it retracts into the gap 36 between the plates.

[0042] Step 2: Drive the movement control system 1 by controlling the electric hoist motor 112 to reach the designated position before the billet reaches the hoisting point. Control the winch motor 117 to drive the irregular hook 13 to descend and completely sink into the gap 36 between the plates to wait for the billet to arrive. At this time, the cylinder 37 on the first transport track 311 drives the movable baffle 35 to rise.

[0043] Step 3: When the billet moves on the first transport track 311 and reaches the hoisting point, the movable baffle 35 stops the billet, and the control hoist motor 117 drives the special-shaped hook 13 to rise to the position. The cylinder 37 on the first transport track 311 drives the movable baffle 35 to retract into the gap 36 between the plates. The electric hoist motor 112 rotates, driving the mobile control system 1 to start transferring the billet to the top of the second transport track 322.

[0044] Step 4: The cylinder 37 on the second transport track 322 drives the movable baffle 35 to rise, and the winch motor 117 drives the irregular hook 13 to descend, completely sinking into the gap 36 between the plates, placing the steel billet completely on the second transport track 322. The movable baffle 35 on the second transport track 322 retracts into the gap 36 between the plates. After the steel billet is transported away, the winch motor 117 drives the irregular hook 13 to rise to its original position.

[0045] Step one is executed once, and steps two, three, and four are executed cyclically in subsequent production processes.
