Description

Technical Field

[0001] This utility model relates to the field of steel coil processing technology, specifically to an automatic steel coil loading trolley. Background Technology

[0002] When using steel coils, they need to be uncoiled by an uncoiler, and the loading trolley is the device that transports the steel coils onto the uncoiler.

[0003] Existing coil loading trolleys can only transport steel coils and cannot adjust their height. However, different models of uncoilers have different heights, making it impossible for general coil loading trolleys to meet the coiling requirements of different models of uncoilers. Furthermore, general coil loading trolleys cannot adjust the direction of the steel coils. When it is necessary to adjust the coiling direction, a hoisting device is required to assist in the coiling, which leads to poor performance of the coil loading trolley. Therefore, we have proposed an automatic coil loading trolley. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic steel coil loading trolley to solve the problems mentioned in the background art, which are that existing loading trolleys can only transport steel coils and cannot adjust their height. However, different models of uncoilers have different heights, which makes it impossible for general loading trolleys to meet the loading requirements of different models of uncoilers. Furthermore, general loading trolleys cannot adjust the direction of the steel coils. When it is necessary to adjust the loading direction, a hoisting device is required to assist in the loading, which leads to poor performance of the loading trolley.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic steel coil loading trolley, comprising a base and a mounting plate, the mounting plate being located at the top of the base, a first hydraulic rod being fixedly connected to the four corners of the bottom of the inner cavity of the base, the ends of the first hydraulic rods being fixedly connected to the four corners of the bottom of the mounting plate, a hydraulic oil tank being fixedly connected to the middle of the bottom of the inner cavity of the base, an oil pump being fixedly connected to the lower side of the left side wall of the hydraulic oil tank, the oil pump being connected to the first hydraulic rods and the hydraulic oil tank via a pipe, a first fixing plate being fixedly connected to the left and right side walls of the base, a cylinder being fixedly connected to the front and rear sides of the top of the first fixing plate, a piston rod being slidably connected to the inner cavity of the cylinder, a second fixing plate being fixedly connected to the end of the piston rod, the second fixing plate being fixedly connected to the left and right side walls of the mounting plate, and an air pump being fixedly connected to the middle of the top of the first fixing plate, the air pump being connected to the cylinder via a pipe.

[0006] As a further description of the above technical solution:

[0007] An exhaust pipe is fixedly connected to the lower side of the outer wall of the cylinder, and a solenoid valve is fixedly connected to the middle of the outer wall of the exhaust pipe via a flange.

[0008] As a further description of the above technical solution:

[0009] A rotating shaft is rotatably connected to the top center of the mounting plate, and a first sprocket is fixedly connected to the outer side wall of the rotating shaft.

[0010] As a further description of the above technical solution:

[0011] A connecting plate is fixedly connected to the end of the rotating shaft, a side plate is fixedly connected to the top of the connecting plate, and a support roller is rotatably connected between the inner sidewalls of the side plate.

[0012] As a further description of the above technical solution:

[0013] The connecting plate has grooves on its left and right side walls, and a second hydraulic rod is fixedly connected to the inner cavity of the groove. A clamping plate is fixedly connected to the end of the second hydraulic rod.

[0014] As a further description of the above technical solution:

[0015] A drive motor is fixedly connected to the top right side of the mounting plate, and a second sprocket is fixedly connected to the end of the power output shaft of the drive motor. The second sprocket is rotatably connected to the first sprocket via a chain.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This automatic coil loading trolley uses an oil pump to deliver hydraulic oil from the hydraulic tank to the first hydraulic rod, causing the first hydraulic rod to lift the mounting plate. Simultaneously, an air pump supplies air into the cylinder, increasing the internal air pressure and pushing the piston rod upward. This piston rod assists the first hydraulic rod in lifting the mounting plate, ensuring stability during the lifting process. Finally, the height of the coil is adjusted by the rising mounting plate, enabling the loading trolley to load coils at different heights from uncoilers, thus improving the trolley's practicality.

[0018] 2. This automatic coil loading trolley retracts the second hydraulic rod, causing the left and right clamping plates to close towards the center. This clamping plates then tighten the coil on the support roller. The drive motor then rotates the second sprocket, which in turn drives the first sprocket via a chain. The first sprocket then drives the rotating shaft, causing the connecting plate to rotate. This, in turn, causes the coil on the support roller to rotate, thus adjusting the direction of the coil. This allows the loading trolley to adjust the direction of the coil, improving its performance. Attached Figure Description

It also allows adjustment of the steel coil orientation, enhancing the overall performance of the loading trolley. Please refer to [link to relevant documentation]. Figure 1-4 It includes a base 100 and a mounting plate 200;

[0028] Please refer to it again. Figure 1-4 A first hydraulic rod 110 is fixedly connected to the four corners of the bottom of the inner cavity of the base 100. The ends of the first hydraulic rod 110 are fixedly connected to the four corners of the bottom of the mounting plate 200. A hydraulic oil tank 120 is fixedly connected to the middle of the bottom of the inner cavity of the base 100. An oil pump 130 is fixedly connected to the lower side of the left side wall of the hydraulic oil tank 120. The oil pump 130 is connected to the first hydraulic rod 110 and the hydraulic oil tank 120 through a pipe. A first fixing plate 140 is fixedly connected to the left and right side walls of the base 100. A cylinder 150 is fixedly connected to the front and rear sides of the top of the first fixing plate 140. A piston rod 160 is slidably connected to the inner cavity of the cylinder 150. A second fixing plate 161 is fixedly connected to the end of the piston rod 160. The second fixing plate 161 is fixedly connected to the left and right side walls of the mounting plate 200. The first fixing plate 140... An air pump 170 is fixedly connected to the top center of the cylinder 150 via a pipe. An air outlet pipe 180 is fixedly connected to the lower side of the outer wall of the cylinder 150. A solenoid valve 190 is fixedly connected to the middle of the outer wall of the air outlet pipe 180 via a flange. The hydraulic oil in the hydraulic oil tank 120 is delivered to the first hydraulic rod 110 by the oil pump 130, so that the first hydraulic rod 110 drives the mounting plate 200 to rise. At the same time, the air pump 170 delivers air into the cylinder 150, so that the air pressure inside the cylinder 150 increases, which in turn pushes the piston rod 160 to rise. In this way, the piston rod 160 assists the first hydraulic rod 110 in driving the mounting plate 200 to rise, thereby ensuring that the mounting plate 200 remains stable when rising. Finally, the height of the steel coil is adjusted by the rise of the mounting plate 200.

[0029] In summary, this enables the winding trolley to wind coils at different heights from the uncoiler, thus improving the trolley's practicality.

[0030] Please see Figure 1-3The mounting plate 200 is located on top of the base 100. Specifically, the mounting plate 200 is fixedly connected to the end of the first hydraulic rod 110. A rotating shaft 210 is rotatably connected to the middle of the top of the mounting plate 200. A first sprocket 211 is fixedly connected to the outer wall of the rotating shaft 210. A connecting plate 220 is fixedly connected to the end of the rotating shaft 210. A side plate 230 is fixedly connected to the top of the connecting plate 220. A support roller 240 is rotatably connected between the inner side walls of the side plate 230. Grooves 250 are formed on the left and right side walls of the connecting plate 220. A second hydraulic rod 260 is fixedly connected to the inner cavity of the groove 250. A clamping plate 270 is fixedly connected to the end of the second hydraulic rod 260. The top right side of the mounting plate 200... A drive motor 280 is fixedly connected, and a second sprocket 281 is fixedly connected to the end of the power output shaft of the drive motor 280. The second sprocket 281 is rotatably connected to the first sprocket 211 via a chain. By retracting the second hydraulic rod 260, the left and right clamping plates 270 are brought together in the middle, thereby clamping the steel coil on the support roller 240. Then, the drive motor 280 drives the second sprocket 281 to rotate, which in turn drives the first sprocket 211 to rotate via a chain. The first sprocket 211 then drives the rotating shaft 210 to rotate, causing the connecting plate 220 to rotate, which in turn drives the steel coil on the support roller 244 to rotate, thereby adjusting the direction of the steel coil.

[0031] In summary, this allows the winding trolley to adjust the direction of the steel coil, thus improving its performance.

[0032] In practical use, those skilled in the art first place the steel coil onto the support roller 240, then retract the second hydraulic rod 260 to bring the left and right clamping plates 270 together, thus clamping the steel coil on the support roller 240. The coil is then transported to the uncoiler by the coiling trolley, and the drive motor 280 drives the second sprocket 281 to rotate. The second sprocket 281, through a chain, drives the first sprocket 211 to rotate, which in turn drives the rotating shaft 210 to rotate. The movement causes the connecting plate 220 to rotate, which in turn drives the steel coil on the support roller 240 to rotate, thereby adjusting the direction of the steel coil to the desired orientation. Then, the hydraulic oil in the hydraulic oil tank 120 is delivered to the first hydraulic rod 110 by the oil pump 130, while the air pump 170 delivers air into the cylinder 150, causing the air pressure inside the cylinder 150 to increase. This causes the piston rod 160 to assist the first hydraulic rod 110 in driving the mounting plate 200 to rise, thereby lifting the steel coil to the upper winding position and completing the upper winding operation.
