Received a 3 A :2006-12-29vo1 .28 No. 3JK a mine elevator shaft-type design and improvement of the attempt - Mao Xi, ranking No. 3 around 28, after flying through the derrick sheave improve container. Thus, the different ways of using spindle, or relax on the wire winding to complete the work to enhance or decrease the container (see Figure 1). Figure 1 Schematic diagram of the shaft 1 single rope lifting equipment. Elevator 2. Hoisting rope 3. Sheave 4. Derrick 5. Cage 1 spindle design, steps 【calculation slightly) Jl (a type of elevator shaft design process, mainly: According to the design requirements of the specification, design meet the requirements of the spindle. Elevator shaft design of the main technical indicators: (1) maximum drag power l400kW; (2) Maximum lifting speed l1.8m / s; (3) maximum static tension difference l15kN. all the design steps: (1) selection based on similar spindle spindle structure (see Figure 2); (2) calculation Spindle types of strength; (3) primary spindle bearings and check them; (4) to select housing. Figure 2 Schematic diagram of the spindle assembly in the design process, should try to use common parts, general components was selected is because the general components of an economic, general, save time, and many other advantages. In the specific design process. Zeyi reliability,[link widoczny dla zalogowanych], security, economy, convenience principle. through each step. spindle design: the first based on the similarity structure by Jing Yan choose a shaft, and then check them to determine whether the strength to meet load requirements and design stiffness of the requirements of the mission statement, does not meet the requirements, then select a larger shaft diameter check, until the selection to the right axis Drive far, and to determine the length of the spindle, shaft reel design, according to the size of the spindle shaft to design big end and small end first axis, the size of the main reference for the design of shaft \based primarily on the spindle shaft. reel support spindle and the fixed wheel connected by a seamless connection with the fixed support wheel rolls connected by bolt connection, easy assembly and disassembly, also install the head shaft bearing, so axis Path choice is stepped shaft, shaft bearings, taking into account the size of choice. because the choice of installation method for the spindle thermal loading, so that one is more secure installation, on the other hand also takes into account the requirements of the installation site, thermal loading ratio key connection more secure. reel installation of two semi-structured, this one is easy to install, on the other hand easy to transport. This design approach has the advantage of thermal loading: easy installation, reliable performance, stable operation,[link widoczny dla zalogowanych], easy maintenance, high efficiency , low noise, low power consumption. but the overall design of the reel, taking into account the co-ordination between the various components, the problem can not be considered in isolation, but the door to try to take into account the volume of economy,[link widoczny dla zalogowanych], practicality, convenience, the Overall design, drawing general assembly drawing, it is necessary to indicate clearly the main interface between the components. 2 improved spindle axis there are many types, this design is a modern mine elevator shaft elevator parts to update products,[link widoczny dla zalogowanych], it improvement and innovation with the following: (1) drum support wheel spindle and the fixed connection with keyless access, roll with the fixed support wheel connected by bolt connection, easy assembly and disassembly. (2) The device uses two cast iron spindle flange. In order to improve the shell of strength and stiffness, using the Q235F shell of thick steel plate (see Figure 3); (3) elevator shaft supported by two o'clock; (4) main bearing double-row radial spherical roller bearings , simplify the installation, simple maintenance, increase efficiency,[link widoczny dla zalogowanych], eliminate axial movement (see Figure 4).; 1 \. {Figure 3 rolls of structure 1. spindle 2. flange 3. support ring spindle bearing device in Figure 4 diagram 1. plate 2. bearing seat 3. spindle 4. Rolling 3 Conclusion Based on the Mine (example) spindle design, methods and steps of the whole process of briefly discussed, and some improvement, introduction of innovative ideas; Wang the design in the future, help the process of practice, so even better.
