该装置用于把工件在两个空间度或三个空间度中,从一点搬运到另一点(例如从一台机床上把工件搬运到另一台机床上)。依次或同时操纵一些远控手柄可实现这一搬运工作。被运送的工件通过一个装在托架座上的伸缩臂可以准确地被抬起、放下或搬动。托架能上下移动,而伸缩臂既能作水平移动,还能环绕垂直轴回转。在托架座上装了一个滑轮。一个连续的能挠曲而不能拉长的牵引构件,一端连于伸缩臂,另一端连于托架座;二者之间有一套滑轮系统,牢引带就绕过托架座上的滑轮和一些装在框架上的定滑轮。不管托架座处于垂直位置的什么地方,也不管托架座是静止不动还是正在运动,伸缩臂都能作水平移动;同时,不管伸缩臂处于水平位置的什么地方,也不管伸缩臂是静止不动还是正在运动,托架座都能作垂直运动。另一个牵引装置用来使托架座移动。在操作工人可及的位置上,有一些手柄用于操作牵引装置。牵引装置的拉力和回弹装置的作用力相反,回弹装置总是力图使伸缩臂和它的托架返回到原始位置去。利用有关驱动装置,如驱动凸轮,就能使伸缩臂和托架座自动地依次进行有节奏的运动。
The unit is used to move workpieces from one point to another in two or three spatial levels (for example, moving workpieces from one machine to another). Followed by or at the same time manipulating some remote control handle to achieve this handling. The transported workpiece can be accurately lifted, lowered or moved by a telescopic arm mounted on the carriage base. The carriage can move up and down, while the telescopic boom moves both horizontally and around the vertical axis. A pulley is mounted on the bracket base. A continuous flexible but can not stretch the traction member, one end connected to the telescopic arm, the other end connected to the bracket seat; between the two has a pulley system, the belt firmly around the bracket seat pulley and Some fixed pulley mounted on the frame. The telescopic arm is able to move horizontally regardless of the vertical position of the carriage base and whether the carriage base is stationary or moving, regardless of where the telescopic arm is in a horizontal position or whether the telescopic arm is stationary Still moving or moving, the bracket seat can make vertical movement. Another pulling device is used to move the carriage base. There are handles for operating the hitch in the position accessible to the worker. The pulling force of the pulling device is opposite to that of the resilient device, which always attempts to return the telescopic arm and its bracket to its original position. By using the relevant driving means, such as the driving cam, the telescopic arm and the carriage base can automatically perform the rhythmic movement sequentially.
