Taking a transmission line in Ganzi Prefecture, Sichuan Province as the research object, based on the detailed survey data of geological hazards collected, the distribution rules of geological hazards along the transmission line were studied through high-precision remote interpretation and field investigation verification. Main results of this paper can be concluded as follows. (1) The results show that there are 89 collapses, 113 landslides, 235 debris flows and 6 unstable slopes along the transmission line, and the geological hazards are distributed in a zonal pattern. (2) The soft clastic rock group is the most widely distributed and has the largest number of collapses and landslides, while the hard clastic rock group has the largest density of geological hazards. (3) The collapse and landslide mainly distributed in the elevation range of 3100m~3700m. (4) The collapse and landslide mainly distributed in the slope range of 10°~40°. (5) The control distance of the fault on the collapse and landslide is 2500m and 1500m, respectively. (6) The control distance of water system and road construction on the collapse and landslide is 600m and 900m, respectively. (7) Fitting the relation of collapse and landslide to fault, water system and road, the practice shows that the fitting effect was perfect by using polynomials and exponential function.
The telescopic boom with single cylinder and pinning system is an important structure of the Gantry crane. In order to avoid the serious consequences of resonance and the optimal design of the telescopic boom with single cylinder and pinning system, the three-dimensional modeling and finite element analysis of the telescopic boom were carried out using SolidWorks and ANSYS Workbench, respectively. The static analysis results, buckling analysis results and modal analysis results of the telescopic boom are obtained, which provides a reference for the design of this type of telescopic boom.
As many enterprises and factories rely on indoor heavy equipment to complete production work, due to the limited indoor working space during the transportation and installation of this heavy equipment, it is more difficult to use traditional lifting devices or large lifting devices due to their large size. It is difficult to enter the room to complete the corresponding work, and each time it is necessary to build and dismantle the lifting device according to the site conditions, resulting in difficult construction, low efficiency, poor versatility, and other problems. Therefore, a new type of indoor installation transportation device is urgently needed to solve this problem. Using innovative design methods to design a new type of installation transportation device is an important method to solve the above problems. Given the current problems of indoor installation transportation devices and the user requirements of such devices, this paper is based on a variety of innovative design theories such as QFD, AD, and TRIZ to research, establish a device innovation design process model, and design a new type of indoor installation and transportation device based on the model, taking GIS indoor heavy equipment as an example, and verify the effectiveness of the device.
