This standard specifies the type of SL worm gear fuel rod lift (hereinafter referred to as the lift). This standard is applicable to worm gear end rod lifts used in metallurgy, machinery, construction, and water conservancy equipment, which have the functions of lifting, lowering, and mechanical propulsion and flipping.
2 Type
2.1 Type
The rod rotates and moves between the axes at the same time (see Figure 1>: The rod rotates, and the fuel rod on the rod moves horizontally (see 2). 2.2 Assembly type
Each type of elevator station configuration is divided into two types of assembly: A-type (or end-to-end movement (see Figure 1 and Figure 2) B-type - end rod (or probe) moves downward (see Figure 1 and Figure 2). 2.3 Type of rod head
Type 1 structural type of screw head is divided into four types: type 1 (return type), type 2 (flange type), type 3 (threaded type) and type 4 (V-type) (see Figure 1);
2 structural type of support rod head is divided into two types: type <type) namely mouth type (combustible type) (see Figure 2). 2.4 Transmission
Elevators are divided into three types of transmission ratios, namely P slow speed 2.5 Protection of operating rod
Type 1 elevator protection classification: basic type, energy-saving type (F>) and energy-saving type (Z): 2 The protection of deep-type elevators is divided into: basic type and type with protective wing (Z). 2.6 Marking example

The maximum allowable power requirement is the multi-effect under the conditions of operating environment of 20T:, working duration of 2C%/h, 2 total efficiency is the light number under the lubrication policy, 3 working cycle limit -26-+C
1In the previous stop state, it can generally be self-operated.
The allowable lifting torque and power of screw drive are shown in Table 4-104. 2
