This standard is proposed by the Ministry of Machinery Industry of the People's Republic of China. This standard is under the jurisdiction of the Beijing Hoisting and Conveying Machinery Research Institute of the Ministry of Machinery. This standard is drafted by the Beijing Heavy Transport Machinery Research Institute of the Ministry of Machinery. This standard is a new standard.0m/s, after the release, the reducer should be used: 7.4.4.2 All kinds of bearings should be equipped with closed node type close monitoring devices. 7.5 Corner station configuration
7.5.1 It is advisable to adopt a symmetrical configuration method with the turning point as the center. 7.5.2 The inlet and outlet reverse curved sections of the external flat rail should share a curved section, and a larger plane function radius should be used. 7.5.3 The internal flat rail should be configured according to the following requirements: When the turning angle is less than 40\, the reverse curved section should share a curved section, and a larger plane curve radius should be used. a.
When the turning angle is 40~60, the reverse curved section should be cancelled, and a straight line section should be shared. 1 When the turning angle is greater than 6, the reverse curved section should be cancelled, and a single large radius curved section should be used to smoothly connect the white line sections at both ends of the station.
GB/T15388.2-94
7.5.4 The design of the hook-up section and the disconnection section shall comply with the requirements of Tables 7.3 and 7.4. 7.5.5 A series of guide plates to limit the swing of trucks should be installed between the first and second station entrances. 7.5.6 When trucks use self-lubricating technology in the corner station, their operating speed should be controlled within the range of 1.6 to 20m/s. 7.5. The exits for empty and loaded trucks should be equipped with facilities that can accommodate more than three trucks. B Trucks
B.1 Training types and basic concepts
B.1.1 Generally, flip-unloading trucks should be selected. When conveying sticky materials, bottom-unloading trucks should be selected. B.1.2 The vehicle capacity should conform to the 0.16, 0.20, 0.25.0.32.0.40, 0.50, 0.63, 0.80, 1.00m series. 8.1.3 The load-bearing capacity of the truck shall comply with the 4,07.1:10.012.5kN rule. 8.1. Under the same thrust capacity, it is advisable to select a truck with larger load-bearing capacity and capacity. 8.1. When measuring the effective load of a 5-liter truck, the load capacity of the truck should be considered: 0.8-0.5 for transporting delicate materials; 1.0 for transporting non-adhesive materials. 8.1.6 The center of the truck should be located at the vertical center of the cable. 8.2 Towing device
B.2.1 The structure of the towing device should meet the following requirements. The mechanism should be flexible and can be smoothly disconnected and hooked with the load. e.
b. Ensure that the gripper is true to the cable and can overcome the climbing angle required by the truck. c. Good durability and ensure that the gripper has a long service life. 8-2.2 There are three types of grabbers: shielded type, four-link gravity type, spring type and weak fixed type. The selection should be based on the different climbing angles of the truck on the line: a. When the line is flat and the truck's slope on the line is less than 18°, it is advisable to use a grab type grabber; b. When the load is complex and the truck's slope on the line reaches 28°, the options are four-link gravity type or spring type grabber; c. When the line is complex, the distance is long, the transmission volume and the vehicle running speed are large, and the truck can be transported more than 30 km/h on the line, it is advisable to use a spring type grabber; d. Fixed type grabber is suitable for non-detachable single-load truck freight roads, and the allowable maximum climbing angle should be within 35~38°.
8.2.3 Calculate the resistance of the towing rope to the adhesion between the jaws and the case. The resistance to sliding under the maximum angle of the load shall not be less than 1.30.
8.3 Hanger
B-3.1 The hanger should be welded and checked for rigidity. The calculated load is the weight of the cargo and the hanger itself and the effective weight.
8.3.2 The C-shaped channel is used. The height of the normal nest must be suitable for the outer dimensions of the selected supporting wheel group. Under the condition of the truck's effective load and the allowable shaking of 20%, it will not touch any part of the supporting rope wheel and leave a space of 0.1 to 0.3. 9 Protective facilities
The protective facilities shall comply with the provisions of Chapter 9 of GB/T1538.1. 10 Brackets
The brackets shall comply with the provisions of Chapter 10 of GB/T1538.1. 11Electrical design
Electrical design shall comply with the provisions of Section 1 of GB/T15388-1. 22
