This utility model discloses an auxiliary device for concrete defect elimination in spillways, belonging to the field of concrete defect elimination technology in hydropower stations. This utility model, by installing fixed pulley assemblies at both ends of the cantilevered support rod and simultaneously suspending baskets on both sides, offers the following advantages compared to traditional cantilever construction baskets: First, it eliminates the need for additional counterweights, balancing safety and economy. The symmetrical force distribution of the baskets on both sides balances the overturning force, eliminating the need for additional counterweights in traditional cantilever devices, reducing costs and simplifying the structure. Second, it improves efficiency through bidirectional construction, significantly shortening the cycle time. Defect elimination can be carried out simultaneously on both sides, avoiding waiting time for single-sided operations, directly improving construction efficiency and shortening the cycle. Third, compared to scaffolding-type work platforms, installation and dismantling time is shorter, operation is convenient, and significantly saves manpower and time costs. Furthermore, the length of this auxiliary device can be flexibly adjusted according to the wall width, adapting to various wall width scenarios.

This utility model discloses a safety belt fastening point device, comprising a round steel bar and an iron plate. One end of the round steel bar is bent into a ring shape as the safety belt fastening point, and the other end of the round steel bar serves as a fixed end. A groove is formed inward from the fixed end of the round steel bar. A shaft hole is formed on the round steel bar at the position corresponding to the groove and along the radial direction of the round steel bar. The iron plate is a right-angled trapezoid, and a connecting hole is formed at the corner of the iron plate opposite to the right-angle end of the iron plate. The side of the iron plate with the connecting hole is inserted into the groove. A pin is inserted through the two shaft holes and the connecting hole. The right-angled side of the iron plate is used to press against the wall. The dynamic load capacity of the round steel bar is ≥12kN. This utility model does not damage the existing building structure and is installed entirely using the existing building structure, making it safe and reliable.

According to the utility model, the capacitor core group, the first polarity terminal, the second polarity terminal, the first IGBT busbar, the second IGBT busbar, the first parallel conducting strip and the second parallel conducting strip are all integrated on the shell, and then are packaged by epoxy resin, so that compared with a conventional filtering device, the integrated filtering device adopts an integrated design, is convenient and easy to install, is short in installation time, and is high in reliability. And the comprehensive cost is reduced.

The application provides an engine assembling device and relates to the technical field of solid rocket engine assembly. The engine assembling device comprises a manipulator, a shifting mechanism, an engine clamping mechanism, a tail wing clamping mechanism and an end sealing installation mechanism which are sequentially arranged in a vertical direction from bottom to top. The movement directions of the engine clamping mechanism, the tail wing clamping mechanism and the end sealing installation mechanism are located on the same axis. The shifting mechanism is used for adjusting the relative position of the engine. The engine clamping mechanism is used for clamping the engine and making the engine reciprocate in the vertical direction. The working end of the manipulator is provided with a clamp mechanism. The above structure is used for installing the engine, and the installation time and labor are short. The problems of process dispersion and numerous influencing factors in the engine assembly and online test in the operation link are avoided. The precision detection is completed in the installation process, the installation precision is ensured, the installation time is shortened, and the safety hidden danger is not prone to occurring in the assembly process.
