Description

Technical Field

[0001] The utility model relates to the field of steel coil transportation, in particular to a rail-type steel coil carrying trolley. Background Art

[0002] Steel coils are industrial products formed by hot and cold pressing steel into coils. During production, steel coils undergo a variety of processes, including cold rolling, surface treatment, finishing, slitting, shearing, blanking, and stamping. However, due to equipment or factory space limitations, such as a lack of internal lifting equipment or the stockpiling area being located outside the factory, steel coil loading cannot be completed within the production line. Therefore, a steel coil trolley is required to transport the steel coils from outside the production line to the production line for loading onto equipment such as the uncoiler.

[0003] In the related art, the method of transporting steel coils is to open a foundation pit on the ground, which is connected to the uncoiling equipment from where the steel coils are placed. Two parallel slide rails are fixedly connected to the bottom of the foundation pit. A trolley used in conjunction with the slide rails is also provided in the foundation pit. The trolley includes a base slidably connected to the upper surface of the slide rails and a supporting platform for placing the steel coils. The base is provided with a drive motor for driving the trolley to move, and a lifting mechanism is provided between the supporting platform and the base to drive the supporting platform to rise and fall. A V-shaped groove is provided on the upper surface of the supporting platform. The steel coil is placed in the V-shaped groove by a lifting device, and the axial direction of the steel coil is consistent with the length direction of the V-shaped groove, so that the V-shaped groove limits the radial direction of the steel coil.

[0004] When conveying steel coils, the trolley is driven by a drive motor to move along the slide rail, transporting the steel coil from the steel coil placement location to the uncoiler. The lifting mechanism is then activated to raise the carrying platform upward, and the steel coil is grabbed and placed on the uncoiler using a robotic arm.

[0005] Regarding the above-mentioned related technologies, the inventor believes that the trolley only limits the radial direction of the steel coil through the V-shaped groove, and in the process of the trolley transporting the steel coil along the slide rail, the steel coil will also shake in the axial direction and may fall from the trolley, causing damage to the steel coil.

[0033] The embodiment of the present application discloses a rail-type steel coil carrying trolley.

[0034] Reference Figure 1-4 The rail-type steel coil trolley includes a trolley body 1 and a slide rail 2. The trolley body 1 slides along the slide rail 2.

[0035] Driving wheels 111 and driven wheels 112 are provided on both sides of the bottom end of the base 11 in the width direction. The driving wheels 111 and the driven wheels 112 are I-shaped wheels. Each slide rail 2 is simultaneously clamped in the groove of the driving wheel 111 and the groove of the driven wheel 112 on one side of the width direction of the base 11.

[0036] A driving shaft is rotatably provided on the base 11. The driving shaft passes through one end of the base 11 in the length direction along the width direction of the base 11, and the driven shaft passes through the other end of the base 11 in the length direction along the width direction of the base 11. Both ends of the driving shaft and both ends of the driven shaft pass out of the base 11. The driving wheels 111 are fixedly coaxially connected to the two ends of the driving shaft, and the driven wheels 112 are fixedly coaxially connected to the two ends of the driven shaft.

[0037] The drive assembly includes two drive motors 3, which are installed on both sides of the base 11 in the width direction.

[0043] The carrier plate 6 includes a first unit plate 61 and a second unit plate 62, both of which are fixed to the top surface of the carrier platform 12 by fixing screws. The first unit plate 61 and the second unit plate 62 are arranged on both sides of the width direction of the top surface of the carrier platform 12. The top surface of the first unit plate 61 is inclined to form a first inclined surface 611, and the top surface of the second unit plate 62 is inclined to form a second inclined surface 621. The lowest side of the first inclined surface 611 and the lowest side of the second inclined surface 621 are arranged close to each other, so that a V-shaped groove 7 is formed in the middle of the width direction of the carrier platform 12.

[0044] The top surface of the supporting platform 12 is also provided with a limiting assembly 8 for limiting the axial position of the steel coil. The limiting assembly 8 includes a fixed plate 81 and a clamping plate 82.

A clamping assembly 9 is provided between the clamping plate 82 and the auxiliary plate 83. The clamping assembly 9 applies a force to the clamping plate 82 so that the clamping plate 82 slides toward the fixed plate 81. A guide block 821 is connected to the bottom surface of the clamping plate 82. A guide groove 822 is provided on the top surface of the supporting platform 12 for the guide block 821 to slide. The cross section of the guide block 821 is inverted T-shaped, and the shape of the guide groove 822 matches the shape of the guide block 821.

[0045] The V-shaped groove 7 limits the radial direction of the steel coil, and the limiting component 8 limits the axial direction of the steel coil, so that the radial and axial directions of the steel coil are limited, which improves the stability of the steel coil during transportation, and the steel coil is not easy to fall from the trolley, thereby avoiding damage to the steel coil.

[0046] The abutment assembly 9 includes a telescopic rod 91 and a abutment spring 92. The telescopic rod 91 includes a first rod body 911 and a second rod body 912 that are slidably connected. One end of the first rod body 911 slides within the second rod body 912, and the other end of the first rod body 911 is fixedly connected to the abutment plate 82 via a limiting circular plate 913. The limiting circular plate 913 is integrally formed on the first rod body 911 and is fixed to the abutment plate 82 via connecting screws. The diameter of the limiting circular plate 913 is larger than the diameter of the first rod body 911. The end of the second rod body 912 away from the first rod body 911 is fixedly connected to the auxiliary plate 83.

[0047] The clamping spring 92 is sleeved on the first rod body 911, one end of the clamping spring 92 is in contact with the limiting circular plate 913, and the other end of the clamping spring 92 is in contact with the second rod body 912. The clamping spring 92 applies a force to the limiting circular plate 913 to make the limiting circular plate 913 slide toward the fixed plate 81. One axial end of the steel coil is in contact with the fixed plate 81, and the other end of the steel coil is in contact with the clamping plate 82, thereby reducing the axial movement of the steel coil and making the steel coil stably located in the V-groove 7.

[0048] The four evenly arranged groups of the pressing components 9 improve the force uniformity of the pressing plate 82. The arrangement of the pressing components 9 can adapt to steel coils with different axial lengths.

[0049] The second rod body 912 is provided with a sliding groove 9121 for the first rod body 911 to slide, and a limiting block 9111 is provided on the outer wall of the first rod body 911. The limiting blocks 9111 are symmetrically arranged on both sides of the radial direction of the first rod body 911. The inner wall of the sliding groove 9121 is provided with a limiting groove 9122 for the limiting block 9111 to slide, so as to prevent the first rod body 911 from slipping off the second rod body 912.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
