Abstract
Description
Technical Field
[0001] The utility model relates to the field of rolling devices, in particular to a novel grate oil cylinder rolling device. Background Art
[0002] The grate hydraulic cylinder is composed of a hydraulic cylinder body, an oil cylinder, a piston and other components. The hydraulic cylinder body and the oil cylinder are sealed. The liquid is pressed into the oil cylinder through the piston to generate thrust or pulling force. After the earrings at the top of the grate oil cylinder are connected to the equipment, the earrings at the bottom need to be fixed with a rolling device. The rolling device can make the earrings at the bottom of the oil cylinder move back and forth along the guide rail.
[0003] Although the existing rolling device is equipped with front and rear guide structures and left and right limit structures, there are still other problems in use, such as poor lateral limit effect. The rolling shaft connected to the earring is positioned by pin insertion. After the device has been used for a period of time, the pin on the rolling shaft often breaks. At this time, the rolling shaft loses the limit, resulting in the shaft escaping and shifting, causing the equipment to stop operating and causing economic losses to customers. It has low safety and does not have a height adjustment function. When the earring at the upper end of the cylinder is fixed and the position of the earring at the lower end deviates from the rolling shaft, the earring cannot be mounted on the rolling shaft due to the distance difference. Therefore, personnel are required to temporarily raise the bottom of the device due to the closed height difference, the operation is cumbersome and complicated, and the practicality is low. In order to solve the above-mentioned problems, we propose a new grate cylinder rolling device. Utility Model Content

[0025] In summary, the utility model has the following beneficial effects:
[0026] 1. The utility model first inserts the rolling shaft into the second U-shaped plate. Before the other end of the rolling shaft comes out of the first U-shaped plate, two rollers and cylinder earrings need to be sleeved on the surface in a front-to-back order. After the other end of the rolling shaft comes out, the sleeve is sleeved on the surface and pushed inward to the bottom. Finally, the second locking nut is taken up and threaded onto the rolling shaft. Good positioning effect can be achieved, and the step of the shaft diameter is used as the right end limit to prevent the rolling shaft from escaping to the left end.
