2results about How to "Improves strength and stability" patented technology

The utility model provides a high-strength light aluminum alloy door and window, which belongs to the technical field of aluminum alloy doors and windows, and comprises a frame, one end of the frame is of a hollow structure with an opening, a plurality of fixing plates are arranged in the frame at intervals along the length direction of the frame, two ends of the fixing plates are oppositely provided with joining plates in opposite directions, and the joining plates are provided with slots and sealing plates in a penetrating manner. The sealing plate is detachably arranged at the opening, a plurality of supporting plates are arranged at intervals in the length direction of the sealing plate, inserting plates capable of being inserted into the inserting grooves are oppositely arranged at the two ends of each supporting plate, limiting mechanisms for limiting the inserting plates are arranged on the connecting plates, the supporting plates are arranged between the adjacent fixing plates, and the supporting plates and the fixing plates form two triangular structures. By arranging the limiting mechanism, inserting the inserting plate into the inserting groove and limiting the inserting plate through the limiting mechanism, rapid installation of the sealing plate and the frame is achieved under the condition that the high-strength stability of the frame is guaranteed, the overall installation steps are simple, and the overall installation efficiency is improved.

This utility model relates to the field of mining engineering equipment technology, and in particular to an intelligent control device for mine filling. It includes a base, a main control box fixedly connected to the top of the base, and two conveying barrels mirror-distributed around the main control box. Flange pipes communicating with the inner walls of the two conveying barrels are fixedly connected to the tops of the two conveying barrels. Flow meters are fixedly connected to the inner walls of the flange pipes. A mixing tank is installed on the outer wall of the base, and a stirring rod is rotatably connected to the inner wall of the mixing tank. A liquid level sensor is fixedly connected to the inner wall of the mixing tank. The flow meter collects the material conveying volume of the main material bin and the auxiliary material bin in real time. The controller automatically compares the actual conveying ratio with the set value, avoiding the mixing ratio error caused by manual observation of material level and manual speed adjustment, ensuring that the ratio of main material to auxiliary material remains stable within a reasonable range. A concentration sensor monitors the mixing state of the filling slurry in the mixing tank, ensuring the basic quality of the filling slurry and improving the strength stability of the filling material.
