斜行电梯变角度机构设计+CAD图纸

摘要斜行电梯不同于一般的垂直电梯,主要运用在一些斜坡状轨迹的提升,节省能量,安全可靠,能够满足15°到75°之间任意角度的条件。斜行电梯一般分为直线运行斜行电梯和曲线运行轨迹斜行电梯两类。针对曲线运行轨迹斜行电梯,有必要设计出一种能够满足变角度导轨的承载机构来保证斜行电梯的平稳安全正常的运行。28025
本设计首先给出了设计方案,然后对方案的每一个部分进行分部设计。分别是对变角度机构,承载架,轿厢座及其相关零件进行了设计。变角度机构部分采用了蜗轮滚珠丝杆升降机的装置来保证斜行电梯过角度时轿厢保证水平,同时根据运动学设计了铰链机构来使杆和承载架进行良好的连接。承载架选取的是合适型号的槽钢来搭建一个与导轨平行的钢架结构,能够承载斜行电梯的上部压力。轿厢座同样选取了合适的槽钢型号来搭建而成,满足了放置轿厢的要求同时与底部的变角度机构较好的进行连接。最后对滚动导靴,铰链机构还有电机座等部分进行了设计,基本使得斜行电梯能够满足安全稳定的度过变角度导轨的要求。

Abstract
Oblique elevator is unlike vertical lift, it is mainly used in lifting things on the sloping track, saving energy, safety and reliability,it can meet the conditions for any angle between 15 ° to 75 °. oblique elevator can be pided in to two kinds : linear movement oblique elevator and curvilinear motion oblique elevator.For curvilinear motion oblique elevator,it is necessary to design a equipment which can meet the variable angle of the Elevator guide rail to guarantee the smooth operation of the oblique elevator.
First of all ,this design choose the best program of the three  kinds of options ,and then design each part of the program, such as the variable angle part , carrying rack, Car seat and so on . variable angle part use the  worm gear lift to guarantee the horizontal movement of elevator. According to kinematics,I design a  hinge mechanism to guarantee
a good connection between the pole and carrying rack. carrying rack use the channel iron to set up a steel to carry the he upper portion of the pressure. Car seat also use the channel iron to build ,it meets the request of the car seat .Finally  I design the elevator guide shoe, the hinge mechanism and the motor seat,the overall program makes the oblique elevator can go through the variable angle  part of  elevator guide rail safety and reliability.
  Keywords: Oblique lift, variable angle, worm screw lift, guide shoe, carrier, car seat
