Description

Technical Field

[0001] This utility model relates to the field of unloading devices, specifically to an unloading trolley. Background Technology

[0002] The unloading trolley is located at the end station of the hot-rolled coil production line. Its main function is to unload the coiled steel coils from the drum and move them to the bundling area. Figure 1 As shown, the existing uncoiling trolley includes a transverse cylinder 1, a frame 2, a lifting cylinder 3, and a coil platform 4. During uncoiling, the transverse cylinder 1 moves the frame 2 laterally to below the coil 5, and the lifting cylinder 3 lifts the coil platform 4 to contact the coil 5. After the coil 5 falls onto the coil platform 4, the transverse cylinder 1 moves the frame 2 and the coil 5 out together. In actual production, it was found that guide rods 6 are installed between the frame 2 and the coil platform 4 on both sides of the lifting cylinder 3. At the moment the uncoiling trolley starts and brakes, the coil 5, weighing several tons, will generate impact pressure on both ends of the coil platform 4 due to inertia. This impact pressure will generate a diagonal component force, which will impact the guide rods 6 and cause lateral vibration. Over time, a gap will appear between the guide rods 6 and the frame 2, causing the coil platform 4 to shake and transmit the vibration to the piston rod of the lifting cylinder 3. In severe cases, this can lead to oil leakage and cylinder explosion of the lifting cylinder 3, which is not conducive to the safe and stable operation of the uncoiling work. Utility Model Content

[0003] In view of the problems existing in the background art, the purpose of this utility model is to provide a winding unloading trolley, which effectively solves the problems existing in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A coil unloading trolley includes a transverse cylinder, a frame, a lifting cylinder, and a steel coil platform. A frustum section is coaxially mounted on the piston rod of the lifting cylinder. Two top blocks, slidably mounted within the frame and cooperating with the frustum section, are symmetrically arranged. Each top block is fixedly connected to a horizontal push rod, and both top blocks are fitted with a tension spring. A support block is fixedly connected to the end of each horizontal push rod. The support block is slidably mounted on the frame, with an inclined top surface and a guide slider. Symmetrically arranged on the steel coil platform are support feet that cooperate with the support blocks, and each support foot has a groove that cooperates with the guide slider.

[0006] Furthermore, a first slider is provided on the front and rear sides of the top block, and a first groove is provided on the frame to cooperate with the first slider.

[0007] Furthermore, the top block is provided with a groove that mates with the tension spring ring.

[0008] Furthermore, a second slider is fixedly provided on the bottom surface of the support block, and a second sliding groove that cooperates with the second slider is provided on the frame.

[0009] Furthermore, the support block is provided with two parallel guide sliders.

[0010] This utility model has the following beneficial technical effects:

[0011] In this invention, the lifting cylinder body drives the support block to move, thereby supporting both ends of the steel coil platform. Compared with the traditional vertical guide slide bar support, the support block can support the steel coil platform through its own material compressive strength, which significantly increases its adaptability and tolerance to impact forces, thus effectively ensuring the stability of the steel coil platform and preventing vibration from affecting the lifting cylinder, which is conducive to the long-term stable and safe operation of the unloading trolley.

[0018] like Figure 2-4 As shown in this embodiment, an uncoiling trolley includes a transverse cylinder 1, a frame 2, a lifting cylinder 3, and a steel coil platform 4. A frustum section 7 is coaxially mounted on the piston rod of the lifting cylinder 3, and the upper end of the piston rod is connected to the steel coil platform 4. Two top blocks 8, slidably arranged in the frame 2 and cooperating with the frustum section 7, are symmetrically arranged. Each top block 8 is fixedly connected to a horizontal push rod 9. A tension spring coil 10 is commonly mounted on both top blocks 8, and the tension spring coil 10 can assist the two... The top blocks 8 move closer to each other and return to their original positions. The top blocks 8 are provided with grooves 11 that cooperate with the tension spring ring 10, which helps to maintain the working position of the tension spring ring 10. The end of the horizontal push rod 9 is fixedly connected to a support block 12. The support block 12 is slidably mounted on the frame 2. The top surface of the support block 12 is inclined and two parallel guide sliders 13 are provided on the top surface of the support block 12. The steel coil platform 4 is symmetrically provided with support feet 14 that cooperate with the support blocks 12. The support feet 14 are provided with grooves that cooperate with the guide sliders 13.

[0019] The assembly structure of the top block 8 and the frame 2 is as follows: the front and rear sides of the top block 8 are respectively provided with first sliders, and the frame 2 is provided with first sliding grooves 15 that cooperate with the first sliders.

[0020] The support block 12 is an assembly structure for the frame 2 as follows: a second slider 16 is fixed on the bottom surface of the support block 12, and a second sliding groove 17 that cooperates with the second slider 16 is provided on the frame 2.

[0021] Lubricating oil is provided between the top block 8 and the frustum section 7, between the guide slider 13 and the slide groove, between the first slider and the first slide groove 15, and between the second slider 16 and the second slide groove 17, which facilitates the relative movement between the components.

[0022] The working principle of this embodiment is as follows:

[0023] After the frame 2 is moved into position by the transverse cylinder 1, the piston rod of the lifting cylinder 3 extends. During the upward movement of the truncated cone section 7, the two top blocks 8 are pushed away from each other. During the outward movement of the top blocks 8, the horizontal push rod 9 pushes the support block 12 to move outward. Since the top surface of the support block 12 is inclined, the top surface of the support block 12 and the support foot 14 always remain in contact. The frame 2 and the support block 12 provide good support for the left and right ends of the steel coil platform 4. When the unloading trolley starts or stops, the steel coil 5 exerts pressure impact on the left or right end of the steel coil platform 4. Compared with the traditional vertical guide slide bar support, the support block 12 can support the steel coil platform through its own material compressive strength, which significantly increases the adaptability and tolerance to impact force, thereby effectively ensuring the stability of the steel coil platform 4 and will not cause vibration impact on the lifting cylinder 3, which is conducive to the long-term stable and safe operation of the unloading trolley.

[0024] When the steel coil platform 4 falls, the truncated cone section 7 descends, the two top blocks 8 move closer to each other, and the support block 12 moves inward. The steel coil platform 4 also maintains contact with the support block throughout the falling process.

[0025] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
