The invention discloses a high-strength powder metallurgy combined inner gear ring and a preparation method thereof, and relates to the technical field of inner gear rings, the high-strength powder metallurgy combined inner gear ring is composed of a section gear ring, a connecting rod, a second embedding rod and a third embedding rod, and an embedding groove is formed in the top of the section gear ring; and mounting grooves are symmetrically formed in the front face and the back face of the section gear ring, second embedding rods are symmetrically installed on the back faces of the connecting rods, and first embedding holes are formed in the inner walls of the back faces of the mounting grooves in a penetrating mode. The four gear ring sections are spliced into the ring shape, then the fixing rods are inserted into the front faces of the gear ring sections and inserted into the third embedding holes, the second embedding rods are inserted into the first embedding holes, and therefore the four gear ring sections can be spliced together to form the combined inner gear ring, and when one gear ring section on the combined inner gear ring is damaged, only the single gear ring section needs to be replaced, and the replacement efficiency is greatly improved. Material waste and fund waste caused by the fact that the whole inner gear ring needs to be replaced when one position of a traditional inner gear ring is damaged are reduced.

This utility model relates to a high-precision pre-embedded bolt positioning frame for hydraulic engineering, including a support frame consisting of two parallel and spaced crossbeams and several cross braces connecting the two; a limiting component, at least two sets of which are connected to the support frame, the limiting component including a web and a flange plate fixedly connected to the top of the web; by opening mounting holes in the support frame to form limiting holes for limiting the installation of pre-embedded bolts, and connecting the limiting component to the support frame, the limiting component can position the support frame between two edge angle steels, so that the mounting holes on the support frame correspond to the pre-embedded positions of the pre-embedded bolts, and ensure that the position after insertion is significantly offset. After the pre-embedded bolt is inserted into the mounting hole, the installation height of the pre-embedded bolt can be adjusted by installing an adjusting nut on the upper end of the pre-embedded bolt extending out of the support frame, and by using the threaded engagement between the adjusting nut and the pre-embedded bolt.

The utility model relates to the technical field of curtain wall, and disclose a spliced curtain wall, including splicing structure and install in the curtain wall spare of splicing structure inside, the front end of splicing structure is provided with the shielding piece, along the recess on the back of the frame and frame moves curtain wall body, and then install the sealant strip on curtain wall body through the cooperation between the mounting block and the mounting groove, and repeat the above operation, make two groups curtain wall body all slide and splice in the frame, then fixed with the help of screw, can complete splicing assembly, simultaneously realize the sealing between two groups curtain wall body with the help of the set sealant strip, and can seal between the mounting block and the mounting groove with the help of the silicone coating, then the fixed plate is in the fixed groove, the fixed plate is fixed on the fixed groove with the help of the bolt, make the fixed plate be at the front end of curtain wall body, can shield the gap between two groups curtain wall body, reduce the interference of outside into the gap area, make the whole sealing property better.

The utility model provides a weighing transfer trolley which comprises a trolley body with a weighing function, a push rod fixedly arranged on one side of the trolley body and a plurality of brake wheels rotationally connected to the bottom of the trolley body, a bearing frame is placed on the top face of the trolley body, and sliding grooves are formed in the two side walls of the bearing frame in the width direction respectively. A sliding groove is formed in the trolley body, the sliding groove is located in the side away from the direction of the push rod, the length direction of the sliding groove is parallel to the length direction of the trolley body, connecting plates are fixedly arranged on the two sides of the trolley body in the width direction respectively, connecting rods are fixedly arranged on one sides of the connecting plates, and the free ends of the connecting rods are arranged in the sliding groove in a penetrating mode. According to the utility model, goods are easily placed on the bearing frame through the bearing frame rotationally arranged above the vehicle body according to the lever principle, so that workers can conveniently load and unload the goods.
