Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical design, in particular to a trolley for disassembling and assembling a step rubber roller. Background Art

[0002] In order to meet the needs of different batteries, improve efficiency and reduce costs, pole pieces of different specifications have been produced on the market. The pole piece coating area is evenly divided into different parts. This kind of pole piece is relatively wide, generally between 1100mm-1500mm, and the required tensile tension can reach 2000N. In the process of roller stretching, high requirements are placed on the tension separation. In view of this, step rubber rollers came into being, such as Figure 6 It is a one-to-five step rubber roller. Each rubber layer of this rubber roller corresponds to a section of the pole piece. Adjacent to each rubber layer are rubber roller spacers. This type of rubber roller has a diameter of 200mm and a weight of 160kg. Due to equipment site restrictions, there is generally not much maintenance space on the equipment. Figure 1 The space for the step rubber roller installation position is very narrow. Usually, when disassembling and assembling the rubber roller, employees will use two hand chain hoists, hanging them at a high place, for disassembly and assembly. However, there is no suitable hanging point for the hand chain hoist directly above the rubber roller. Therefore, the hand chain hoist is used at an angle during disassembly and assembly, especially when installing, it is difficult to find the correct position of the rubber roller. This operation has great safety risks and also brings a lot of inconvenience to equipment maintenance. Therefore, there is a great need for a device to conveniently, quickly and safely disassemble and assemble this type of step rubber roller. Utility Model Content

[0032] One end of the top of the support plate is an arc-shaped structure, and the other end is provided with a locking block; the locking block is connected to the support plate by bolts.

[0033] Here is a more specific description:

[0034] First, let's take a look at the working environment of the rubber roller. Figure 1 , Figure 2 and Figure 6The rubber roller is located under the steel roller and installed on the swing arm. It is pressed by the swing arm pressure cover. There is a cylinder under the swing arm. The cylinder piston is pushed out to lift the swing arm, so that the rubber roller is pressed on the steel roller, thereby isolating the tension of the pole piece. There is a connecting beam at the lower right side of the rubber roller, which can be used as a fulcrum to install the track of the rubber roller disassembly tooling.

[0035] When you need to remove the rubber roller, follow the steps below:

[0036] 1. Cylinder pressure relief;

[0037] 2. Remove the swing arm gland;

[0038] Install two rubber roller track fixing blocks on the connecting beam and set the distance between the two fixing blocks according to the needs. In this case, the distance between the track fixing blocks is 1332mm. Figure 3 shown.

[0039] Use M8x20 hexagon socket screws to fix the two rubber roller tracks on the track fixing block. Do not tighten the screws, so that the upper surface of the track just touches the rubber roller spacer without falling off. Figure 4 As shown;

[0040] Install two rubber roller support blocks on the special hydraulic lift truck;

[0041] Push the hydraulic car with the support block between the flattening device and the buffer device, find a good position, step on the brake, and raise the hydraulic car. When the upper surface of the hydraulic car contacts the rubber roller track, continue to rise. At this time, you can slowly lift the rubber roller until the upper surface of the rubber roller track rises to the same level as the upper surface of the rubber roller support block, and then fix the rubber roller track to the upper surface of the hydraulic car with screws. Figure 7 At this time, the rubber roller has been lifted up by the rubber roller track, and then the rubber roller is rolled along the track to the rubber roller support block; after the rubber roller is in place on the support block, the locking block is installed to prevent the rubber roller from falling off, and the support block is provided with a hole for installing the stopper;

[0042] Remove the track fixing screws on the hydraulic cart, lower the height of the hydraulic cart to the lowest position, pull the rubber roller out from the middle of the equipment, and perform maintenance.

[0043] The steps for installing the rubber roller are basically the opposite of the steps for removing it, as follows:

[0044] Install two guide rail fixing blocks and two rubber roller guide rails on the connecting beam;

[0045] Lower the height of the special hydraulic vehicle to the minimum, install two rubber roller support blocks on the hydraulic vehicle, and install the locking blocks;

[0046] Put the rubber roller on the hydraulic car support block.

[0047] Push the rubber roller to the front of the flattening device, slowly raise the hydraulic car until the upper plane of the support block and the upper plane of the track are at the same level, find the correct position, step on the brake, and fix the rubber roller track;

[0048] Slowly push the rubber roller toward the bearing position of the rubber roller swing arm;

[0049] Pass compressed air into the cylinder to push the cylinder push rod out slowly, lift the swing arm and support the rubber roller bearing;

[0050] Remove the track fixing screws on the hydraulic car, slowly lower the height of the hydraulic car to the lowest, and then pull the hydraulic car out from between the flattening device and the buffer device. Finally, cover the swing arm pressure cover and fix the rubber roller.

[0051] At this point, the replacement of the rubber roller is completed. There is no risk of the step rubber roller falling during the entire operation. This set of equipment has effectively solved the problem of difficult disassembly and assembly of the step rubber roller due to narrow space and limited use of tools, and has greatly reduced the safety risks during the disassembly and maintenance of the rubber roller.
