Description

Technical Field

[0001] This application relates to the technical field of rubber roller production, and particularly to a rubber roller lifting device. Background Art

[0002] In the process of rubber roller manufacturing, there are multiple processes. To complete these processes, the semi-finished rubber rollers need to be transferred between different machines. Since the outer circumference of the rubber roller is coated with a rubber layer, the middle part of the rubber roller cannot be directly lifted. Instead, the steel wire rope can only be hooked at both ends of the rubber roller. And to prevent the steel wire rope from scraping on the side of the rubber roller, some rubber roller lifting devices have been designed. For example, a Chinese patent with the application number 202223069669.5 discloses a single roller hoist, which includes a lifting beam. At positions near both ends of the lifting beam, adjusting plates are symmetrically arranged. A position adjusting component is installed between the adjusting plate and the lifting beam. At positions near the bottom end of the adjusting plate, first shackles are symmetrically installed. A first wire rope sling is commonly installed on the two first shackles. Hanging ears are symmetrically and fixedly installed at the top of the lifting beam. Second shackles are respectively installed on the two hanging ears. A second wire rope sling is installed on the second shackle. Telescopic columns are symmetrically installed at the bottom of the lifting beam. This hoist can pull up the adjusting plate and clamp it at different positions according to the length of the rubber roller to achieve position adjustment. However, for large rubber rollers with a weight of 10 to 20 tons, the supporting hoists and wire ropes are made of steel and are relatively heavy. It is difficult for workers to lift the adjusting plate manually, increasing the labor intensity of the workers. Therefore, a rubber roller lifting device is needed in which a pry hole is provided between the upper part of the adjusting plate and the limit block, and workers can use a crowbar to pry up the adjusting plate and then move it to other limit blocks to reduce the physical strength consumed when lifting the adjusting plate. Summary of the Utility Model

[0003] To solve the above problems, this application proposes a rubber roller lifting device in which a pry hole is provided between the upper part of the adjusting plate and the limit block, and workers can use a crowbar to pry up the adjusting plate and then move it to other limit blocks to reduce the physical strength consumed when lifting the adjusting plate.

[0004] This application is achieved through the following technical solutions:

[0005] This application proposes a rubber roller lifting device, including:

[0006] A main beam, on which hanging ears are symmetrically arranged, and the hanging ears are connected to the lifting equipment through a first wire rope;

[0007] An adjusting plate, the upper part of which is clamped on both sides of the main beam, and a secondary beam is provided at the lower part of the adjusting plate, and the secondary beam is connected to both ends of the rubber roller through a second wire rope;

[0008] Among them, a plurality of limiting blocks are arranged at intervals at both ends of the main beam. A connecting hole is provided in the upper part of the adjusting plate. The adjusting plate is clamped between the limiting blocks through the connecting hole, and the upper part of the connecting hole is 3 cm to 5 cm higher than the upper end surface of the limiting block.

[0009] Further, the distance between the limiting blocks is the same as the thickness of the adjusting plate.

[0010] Further, the widths on both sides of the limiting block are smaller than the width inside the connecting hole.

[0011] Further, the limiting blocks are arranged on the upper part of the main beam. When the adjusting plate is lifted, the connecting hole is separated from the limiting block.

[0012] Further, lifting rings are provided on both sides of the auxiliary beam, and both ends of the second steel wire rope are sleeved on the lifting rings.

[0013] Further, numbers are marked on the limiting blocks, and the numbers on the limiting blocks on both sides of the main beam are the same.

[0014] The beneficial effects of the present application: By arranging limiting blocks on the main beam, the adjusting plate can adjust its position according to the length of the rubber roller, and it is not easy to slide after adjustment, improving the safety of lifting. The upper part of the connecting hole is higher than the upper end surface, and workers can insert a crowbar into the connecting hole and use the lever principle to lift the adjusting plate, so as to reduce the physical strength consumed when lifting the adjusting plate.

[0024] As Figures 1 to 5 shown, an embodiment of the present invention provides a rubber roll lifting device, including: a main beam 1, on which hanging ears 2 are symmetrically arranged, and the hanging ears 2 are connected to a lifting device through a first steel wire rope 3; an adjusting plate 4, the upper part of the adjusting plate 4 is clamped on both sides of the main beam 1, a secondary beam 5 is arranged at the lower part of the adjusting plate 4, and the secondary beam 5 is connected to both ends of the rubber roll through a second steel wire rope 6; wherein, a plurality of limiting blocks 7 are arranged at intervals at both ends of the main beam 1, a connecting hole 8 is arranged at the upper part of the adjusting plate 4, and the adjusting plate 4 is clamped between the limiting blocks 7 through the connecting hole 8, and the upper part of the connecting hole 8 is 3 cm to 5 cm higher than the upper end surface of the limiting block 7.

[0025] When lifting, it is necessary to first adjust the position of the adjusting plate 4 according to the length of the rubber roller. When adjusting, insert the crowbar into the gap between the connecting hole 8 and the limit block 7, then pry the crowbar, and use the lever principle to tilt the adjusting plate 4. After the connecting hole 8 and the limit block 7 are completely separated, the adjusting plate 4 will slide down along the crowbar under the action of gravity, and can be adjusted one grid at a time. After prying multiple times, the adjustment of the position of the adjusting plate 4 can be completed. Then, the main beam 1 is connected to the lifting equipment through the first steel wire rope 3, and the main beam 1 is moved to above the rubber roller. After the two ends of the rubber roller are connected to the auxiliary beam 5 through the second steel wire rope 6, the rubber roller is lifted by the lifting equipment. During lifting, the adjusting plate 4 is located above the connection position, so that the second steel wire rope 6 is perpendicular to the axis of the rubber roller, thereby preventing the steel wire rope from scraping the rubber layer of the rubber roller, and the adjusting plate 4 is limited by the limit block 7 to prevent it from sliding on the main beam 1, thereby ensuring the safety of lifting.

[0026] Specifically, the spacing of the limit blocks 7 is the same as the thickness of the adjustment plate 4. The limit blocks 7 are used to limit the two sides of the adjustment plate 4 to prevent the limit blocks 7 from sliding on the main beam 1 during lifting, thereby ensuring safety during lifting.

[0027] Preferably, the width on both sides of the limit block 7 is smaller than the width on the inner side of the connecting hole 8, and the limit block 7 mainly limits the two sides of the upper half of the connecting hole 8. When the adjustment plate 4 is tilted, the connection hole 8 is completely separated from the limit block 7 because the width on both sides of the limit block 7 is smaller than the width on the inner side of the connecting hole 8. At this time, the adjustment plate 4 slides under the action of gravity to complete the adjustment operation.

[0028] Specifically, the limit block 7 is arranged on the upper part of the main beam 1. When the adjustment plate 4 is lifted, the connection hole 8 is separated from the limit block 7. At this time, the adjustment plate 4 slides under the action of gravity to complete the adjustment operation.

[0029] In a preferred embodiment, lifting rings 9 are provided on both sides of the auxiliary beam 5, and both ends of the second steel wire rope 6 are sleeved on the lifting rings 9. The lifting rings 9 can quickly connect and disconnect with the second steel wire rope 6, thereby improving the convenience of operation.

[0030] In a preferred embodiment, the limit blocks 7 are marked with numbers, and the numbers on the limit blocks 7 on both sides of the main beam 1 are the same, so that workers can intuitively know the fixed position of the adjustment plate 4 and adjust the adjustment plates 4 on both sides to balance the force on the main beam 1.

[0031] Of course, the present application may have many other implementations. Based on the present implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present application.
