2results about How to "Add limit function" patented technology

The application relates to a limiting device in the climbing process of a bridge high-pier climbing frame; the limiting device comprises a plurality of bearers, the bearers are rotationally connected on a middle platform of the climbing frame respectively, each bearer is perpendicular to the facade of the bridge high-pier, at least one roller is arranged on the side of the bearer close to the bridge high-pier, the roller is preferably a universal roller, the bearer is rotationally connected with the middle platform through a turnover mechanism, the bearer is fixedly connected with the turnover mechanism, the angle change between the bearer and the middle platform is realized through the movement of the turnover mechanism, and the bearers are arranged on the four edges of the middle platform; the application realizes the limiting effect of the climbing frame in the X and Y directions in the horizontal direction, strengthens the limiting function of the climbing frame, and guarantees the construction safety and construction quality.

The utility model belongs to the seedling planting technical field, especially for a kind of drought-resistant water-collecting water-retaining device for seedling planting, including liquid storage cylinder, the upper surface of liquid storage cylinder is open structure, the lower side wall of liquid storage cylinder is fixedly installed with round sleeve, and the upper and lower side of round sleeve are all open structure, the lower side wall of liquid storage cylinder is evenly provided with liquid distribution mechanism along round sleeve, the inner wall of liquid storage cylinder and the outer surface of round sleeve are fixedly installed with baffle, liquid-collecting mechanism is arranged on the baffle near left and right positions, and the left and right side walls of baffle are fixedly installed with limiting mechanism on the upper side of baffle;The utility model is collected and preserved to water by liquid storage cylinder, reduces soil moisture loss at seedling, and the root system of seedling is drip irrigation by liquid distribution mechanism, ensures that water can meet the growth demand of seedling, increases the limiting function to seedling simultaneously, so that seedling is not easy to dump, improves the survival rate of seedling.
