Description

Technical Field

[0001] This utility model relates to the technical field of lifting devices, and in particular to a plate and strip lifting device based on wedge adjustment. Background Technology

[0002] Currently, in the production process of Maanshan Iron & Steel's galvanizing line, the strip needs to be conveyed and guided by multiple guide rollers. Because the roller surfaces are in close contact with the strip, severe wear occurs after prolonged use, necessitating periodic replacement. However, the strip itself is quite long, and its continuous pressure on the guiding roller surfaces makes each roller replacement extremely difficult.

[0003] In existing technologies, changing rollers requires using tools to forcibly pry up the strip to remove the worn rollers and replace them with new ones. This method not only consumes a lot of manpower and time, reducing production efficiency, but also easily causes scratches, indentations, and other defects on the strip surface during the prying process, affecting product quality and causing unnecessary losses to the company. Therefore, developing a device that can conveniently and safely lift the strip and assist in changing the guide rollers has become an urgent problem to be solved. Utility Model Content

[0022] Please refer to Figures 1 to 4As shown, this utility model discloses a strip lifting device based on wedge adjustment to solve the technical problem in the prior art that when replacing the guide rollers of the Maanshan Iron and Steel galvanizing line, it is time-consuming, laborious and easy to damage the surface of the strip by prying the strip to change the rollers. To achieve the above objectives, this utility model provides the following technical solution: a strip lifting device based on wedge adjustment, comprising a base assembly 100, a rubber roller 200, a wedge lifting assembly 300, and a screw adjusting assembly 400. The rubber roller 200 is mounted on the base assembly 100 via the wedge lifting assembly 300, and the screw adjusting assembly 400 is mounted on the wedge lifting assembly 300. The wedge lifting assembly 300 includes a first slide assembly and a second slide assembly. The rubber roller 200 is mounted above the base assembly 100 via the first slide assembly and the second slide assembly. The first slide assembly includes a first wedge slide 301a and a second wedge slide 301b. The first wedge slide 301a is fixed to the base assembly 100, and the second wedge slide 301b is slidably disposed on the first wedge slide 301a. The inclined surfaces of the first slide assembly each have corresponding concave and convex stepped surfaces. The first wedge-shaped slide block 301a and its two vertical surfaces are provided with arc-shaped grooves, in which arc-shaped copper sliders 600 are disposed. The second slide block assembly includes a second wedge-shaped slide block 302a and a second wedge-shaped slide block 302b. The second wedge-shaped slide block 302a is fixed on the base assembly 100, and the second wedge-shaped slide block 302b is slidably disposed on the second wedge-shaped slide block 302a. The inclined surfaces of the second slide block assembly have matching concave and convex stepped surfaces.

[0023] It should be noted that the device uses a wedge-shaped structure to adjust the height of the guide roller 200, thereby achieving smooth lifting of the strip. The core component is the wedge-shaped lifting assembly 300, which consists of two sets of slides. Each set of slides has interlocking concave and convex steps on its inclined surface, ensuring smooth movement along the inclined surface without lateral deviation during sliding. When the operator rotates the screw adjustment assembly 400, the screw 402 drives the arc-shaped copper slider installed therein to slide along the inclined surface of the slide, thereby pushing the upper slide to rise or fall, achieving a change in wedge height. Due to the reasonable design of the inclined angle of the slide, a small rotation of the screw 402 can be amplified into a large vertical displacement, thus achieving efficient force transmission and displacement amplification, allowing the roller 200 to be lifted smoothly, lifting the strip and separating it from the original guide roller. The wear-resistant rubber layer covering the roller 200 provides flexible support, preventing scratches on the strip surface. The entire adjustment process is structurally stable and easy to operate. The guide roller 200 can be replaced without prying the strip, thereby significantly improving the roller replacement efficiency and ensuring the surface quality of the strip.

[0024] The adjustment assembly includes a nut 401 and a screw 402. The screw 402 passes through the center holes of two arc-shaped copper sliders 600 in the wedge-shaped lifting assembly 300. A nut 401 needs to be installed on the arc surface of one of the arc-shaped copper sliders 600 to limit the axial movement of the screw 402. A nut 401 also needs to be installed on the plane of the other arc-shaped copper slider 600. By twisting the nut 401, the screw 402 is driven to extend and retract, thereby realizing the vertical height adjustment of the wedge-shaped lifting assembly 300. The height adjustment range is 0-60mm. The adjusting component uses a threaded drive, which is simple and labor-saving to operate. It can precisely control the height of the wedge lifting component 300. When the guide roller 200 needs to be replaced, the wedge lifting component 300 is raised by adjusting the component, so that the roller 200 lifts the strip and can lift the strip 20mm away from the roller surface of the guide roller 200. At this time, the strip is no longer in contact with the guide roller 200 to be replaced. The operator can easily remove the old roller and install the new roller. After the roller replacement is completed, the reverse twist nut 401 is used to lower the wedge lifting component 300, and the strip falls back to the surface of the new roller 200. The whole process does not require prying the strip, thus avoiding damage to the strip.

[0025] Bearing seats 500 are correspondingly arranged above the first and second slide assemblies. Their function is to mount and support both ends of the rubber roller 200 shaft, enabling stable rotation of the rubber roller 200. Specifically, the two slide assemblies achieve precise overall height adjustment through a wedge-shaped structure, while the bearing seats 500 on them rise or fall synchronously with the slides, thereby driving the overall lifting and lowering of the rubber roller 200. When the screw adjusting assembly 400 drives the wedge-shaped slides to slide relative to each other, the vertical displacement of the slides is directly transmitted to the rubber roller 200 through the bearing seats 500, achieving the lifting or lowering of the strip. The corresponding arrangement of the bearing seats 500 ensures that the rubber roller 200 remains horizontal during lifting, avoiding skewing or jamming caused by inconsistent heights at both ends. Simultaneously, the bearing seats 500 reduce the frictional resistance of the rubber roller 200 during rotation, ensuring smooth operation and providing continuous and smooth support and guidance for the strip, thereby improving the overall reliability and accuracy of the device.

[0026] The base assembly 100 includes a base body 101 and two baffles 102. The top of the base body 101 has a slot, the size of which is adapted to the existing 16# channel steel. The baffles are fixedly installed on both sides of the base body 101, and the baffles cooperate with the side walls of the slot to limit and fix the 16# channel steel embedded in the slot. The base assembly 100 is installed by fitting with the existing 16# channel steel on site through the slot, without requiring large-scale modifications to the on-site equipment. Installation is convenient and highly stable. The baffles prevent the base body 101 from shifting relative to the channel steel during use, ensuring the overall stability of the device.

[0027] The surface of the rubber roller 200 is covered with a wear-resistant rubber layer, which can enhance the wear resistance of the rubber roller 200 and extend its service life. At the same time, the rubber material has a certain elasticity, which can further reduce frictional damage to the surface of the strip.

[0028] The working principle of this device is as follows: the smooth lifting and lowering of the belt is achieved through the mechanical transmission of the wedge structure, thereby assisting in the replacement of the guide roller 200. Specifically, the device consists of a base assembly 100, a wedge lifting assembly 300, a screw adjusting assembly 400, and a roller 200. The wedge lifting assembly 300 consists of two sets of independent slide structures. The inclined surface between each set of slides is designed with matching concave and convex steps to maintain stable guiding accuracy during sliding. When the operator rotates the screw adjusting assembly 400, the screw 402 drives the arc-shaped copper slider set therebetween to slide along the inclined surface of the wedge-shaped slide, pushing the upper slide relative to the lower slide to produce a vertical displacement, thereby driving the bearing seat 500 and the roller 200 fixed on it to rise or fall as a whole. The wear-resistant rubber layer covering the roller 200 provides flexible support and scratch protection when in contact with the belt. When the rubber roller 200 is raised to a height higher than the on-site guide roller 200, the strip is lifted and separated from the original guide roller, allowing workers to easily disassemble the old roller and install the new one. After adjustment, rotating the screw 402 in the opposite direction lowers the rubber roller 200, and the strip returns to its working position. The entire process requires no prying of the strip, is simple to operate, and provides precise positioning, significantly improving roller changing efficiency and effectively preventing damage to the strip surface.
