Embodiment 1
[0104] Such as Figure 1-Figure 3 As shown, a mobile greenhouse includes a mobile car 1, a heater 2, a flame-retardant cotton cloth 3, and a steel wire rope 5. The mobile car 1 is a three-dimensional structure welded by square steel, including a beam 11 and a longitudinal beam 12, The outer side of the longitudinal beam 12 is welded with a small pulley support column 13, and the top of the small pulley support column 13 is welded with a small pulley 14;
[0105] Both ends of the steel wire rope 5 are provided with buckles 6, which are detachably connected to the rails 4 of the ballast bed. Pulley 14, the wire ropes 5 that pass through the small pulleys 14 on both sides of the mobile trolley 1 respectively are parallel to each other;
[0106] The four corners of the bottom of the mobile trolley 1 are equipped with universal simple pulleys 15 adapted to the ballast rail 4, and the lower beam 11 of the mobile trolley 1 is welded with a heater support frame 16, and the heater sup...
Embodiment 2
[0188] Application background: The first phase project of Hohhot Rail Transit Line 1 starts from Sanjianfang Depot in the west, and goes east along Xinhua West Street to Baita Parking Lot. There are 20 stations on the main line, one depot at the west end of the line, and one parking lot at the east end of the line. The total track laying length of the whole line is 69.7km, including 51.7km track laying for the main line and 18km track laying for the field section. A total of 5 track laying bases are set up for the whole line. According to the overall construction period arrangement and the handover of the working surface, about 70% of the track laying on the whole line will be constructed in winter.
[0189] This area belongs to the mid-temperate continental monsoon climate, with obvious seasonal climate changes and large differences. Its characteristics are: long and severe winter, short and hot summer, and severe climate change in spring and autumn. The average temperature ...
