提升滑轮

Uncontrolled acceleration forces can cause belt conveyor system performance problems with vertical curves, excessive belt take-up movement, loss of drive pulley friction, spillage of materials, and festooning of the belt fabric.

毫无控制的加速度产生的动力能够引起带式传送机系统产生诸多不良问题，比如上下曲线运动、过度传送带提升运动、滑轮和传送带打滑、运输原料的溢出和传送带结构。

The key point of the structure of the utility model is that: the other side of the reducer that is arranged on the platform is provided with a hoisting device; the roller shaft end of the electronic controlled windlass is provided with a hub, a damper brake is arranged outside the hub; the input castellated shaft of the reducer that is arranged on the electronic windlass is provided with duplicate gears that have different amount of teeth.

本实用新型包括标准节，两侧标准节的中间为平台，电控卷扬机的卷绳通过平台上的滑轮同吊盘相连；平台上的减速器的一侧设置有可提升平台的具有卷绳的滚筒，平台上设置有具有滑轮的支架，其结构要点平台上的减速器的另一侧设置有提升装置；电控卷扬机的滚筒轴端设置有轮毂，轮毂外设置有制动闸；电控卷扬机的减速器的输入花键轴上设置具有不同齿数的双连齿轮，双连齿轮之间的凹槽内的拨杆同减速器外的摇把相连。

Also sheers (used with a sing. or pl. verb)An apparatus used to lift heavy weights, consisting of two or more spars joined at the top and spread at the base, the tackle being suspended from the top.

也作 sheers起重三角架：用来提升重物的器械，由两个或多个在顶部连接而在基部分散的桁杆构成，顶部挂有滑轮

"Derrick:a machine for hoist ing and moving heavy objects, consisting of a movable boom equipped with cables and pulleys and connected to the base of an upright stationary beam."

悬臂起重机：提升和移动重物的机器，它由一个带有缆绳和滑轮的可移动的、并与一根由向上静止横梁的底座连接的起重杆组成。

The wire rope pulled by the lifting mechanism wind through the 2 guiding blockof the pillar and cross the fall block, fix and suspend on the weight limiting instrument of the pillars, the operation staff can control the up and down movement and stop movement of the suspension coop by the control board.

提升机构拉出的钢丝绳绕过顶梁的两只导向滑轮穿过吊笼上的动滑轮，固接、悬挂在顶梁之上的重量限制器上，操作人员通过操纵台控制吊笼的上下运动和停止动作。

The methods to simulate the wrapping of the wire rope on pulleys and the varying elasticity of wire may give a reference to the system dynamics study for the similar structures varying with time,such as drilling rig,oil well hoisting system.

该仿真模型中解决钢丝绳与滑轮间的缠绕和钢丝绳的刚度随时间变化的方法也可为研究钻机、矿井提升系统等类似的时变结构系统动力学时借鉴。

Overload preventers with strain gauges The strain gauges or load cells can be built-in directly behind a deadend of a hoisting wire rope or in a yoke which is carrying wire rope sheaves, or underneath a gear-box.

配有应变仪的防过载装置把应变仪或称重传感器直接内置在提升钢丝绳的固定端后面，或内置在牵引钢丝绳的滑轮轭中，或内置在齿轮箱下面。
