Abstract

The invention relates to an elevation travel switch limiting device, which is characterized by comprising a deep groove ball bearing and a shaft, which are installed inside a shaft seat, wherein two ends of the shaft stretch out of the shaft seat, one end of the shaft is provided with a first wheel hub and a second wheel hub through flat keys, and the surface of the first wheel hub and the surface of the second wheel hub are respectively provided with an annular installation groove, and a link stopper is respectively installed inside the annular installation grooves of the first wheel hub andthe second wheel hub; a travel switch fixed seat is installed on the shaft seat, a travel switch installation seat is respectively installed on two ends of the travel switch fixed seat, a travel switch is respectively arranged on each travel switch installation seat, and one travel switch and the first wheel hub and another travel switch and the second wheel hub are installed at the same side of the travel switch fixed seat. An oil seal and a retainer ring are arranged between the shaft and the shaft seat. An elastic retainer ring for a hole, a small round nut and an O-shaped sealing ring arearranged at the outer side of the deep groove ball bearing. The elevation travel switch limiting device is stable and reliable, and the produced mechanical error is small; and the position of each part is relatively fixed, so the elevation travel switch limiting device is easy to adjust and maintain.

Description

technical field [0001] The invention relates to a limit device for a lifting mechanism, in particular to a limit device for a lift stroke switch. Background technique [0002] In the field of modern industrial control, automatic control has been widely used. Automatic control belongs to the control that people do not directly participate in. Then this system must have the ability to automatically collect and process signals, and the accuracy of signal collection becomes automatic control. The key to whether the degree and control actions are correct. There are some shortcomings in the existing information collection component structure, mainly as follows: ①The electronic collector installed in the way of chute is easy to loosen, which leads to the expansion of control error; ②It is extremely inconvenient to carry out factory debugging and equipment maintenance and adjustment. Contents of the invention [0003] The object of the present invention is to overcome the deficie...
