MT 234-91
Product classification, technical requirements, test methods, inspection regulations and marking, packaging, transportation and storage of multi-rope cage for vertical shaft (hereinafter referred to as cage). This standard specifies the product classification, technical requirements, test methods, inspection regulations and marking, packaging, transportation and storage of 3t mine car
This standard is suitable for 3t mine car vertical multi-rope cage. The cage is used in conjunction with a multi-rope friction hoist and a combined steel seam way to lift 3t standard mine cars, equipment or personnel.
This standard is used in conjunction with the head rope suspension device, tail rope suspension device and roller ears. : : : : : : : : : : : : : : : 3.2 Head rope suspension device: the connecting device between the tank body and the lifting rope. 3.3 Tail rope suspension loading: the connection device between the balance wire rope and the bottom of the tank body (there are two types of tail rope suspension devices: round and flat). 3.4 Overwinding tank support anti-reverse claw device: a safety device to prevent the cage from falling after it is overwinding at the wellhead. 3.5 Four-corner ears: The cage is at the level of the vehicle entering and exiting, and is set at the four corners of the cage as a guide to stabilize the cage. Approved by the Ministry of Energy of the People's Republic of China on February 2, 1991 and implemented from May to January 1991
3.6 Brake tank ear: a rigid seam ear that enters the wedge-shaped tank channel. 4 Product classification
4.1 Varieties

4.2.2 The head rope suspension device is directly connected to the tank body. The center distance of the connecting holes is determined by the winch rope pitch. The tail rope suspension device is provided with two types: round tail rope and flat tail rope.
4.2.3 Cover doors are installed at both ends of the upper, middle and lower plates of the tank (the lower plate cover door is locked with bolts) to facilitate the lowering of long materials or as an emergency safety exit.
4.2.4 The cage door is a curtain-type door that opens and closes from top to bottom. 4.2.5 A removable safety canopy is installed on the top of the cage. 4.2.6 The tank body is made of steel columns, which are connected to the plates with high-strength bolts. 4.2.7 The cage adopts the shaking table support method. The guide linings overlapped with the shaking table are divided into type 1 (groove type) and type 1 (flat type) to adapt to different types of shaking tables.
4.2.8 The six types of cages in this standard are all equipped with adjustable weights inside the chassis, which can be selected according to the anti-skid requirements of the elevator. 4.2.9 The rail surface boss and upper car stopper are used inside the tank and are used in conjunction with the anti-pull device outside the tank. The car stopper is opened and closed by an externally fixed opening and closing curved track (see Appendix E).
4.2.10 The upper layer of the three-layer cage has no track and is only used for lifting personnel. 4.2.11 The middle plate of the two-layer wide tank and the lower middle plate of the three-layer wide tank are made detachable to facilitate the loading and transport of electric locomotives, hydraulic supports and other large equipment.
