Description
Technical Field
The utility model relates to a handle operating mechanism based on a deviation switch, which is used in the field of a transmission belt deviation switch.
Background
The existing conveyor belt deviation switch products in the market have the defects of low reliability, short service life and complex mechanism.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides a handle operating mechanism based on a deviation switch, which has a compact structure and can realize signal output of the deviation switch of a conveyor belt.
The technical scheme for achieving the purpose is as follows: a handle operating mechanism based on a deviation switch comprises a handle roller, a support shaft and a handle seat;
the handle operating mechanism is fixed in a set position through the installation of handle seat, the back shaft is connected with the handle seat, the handle cylinder has been cup jointed in the back shaft outside, the both ends of handle cylinder are equipped with a handle lid respectively, both sides handle lid position department is equipped with the bearing on the back shaft, be equipped with cam micro-gap switch in the handle cylinder, drive cam micro-gap switch through cam structure when handle cylinder rotates and rotate and send the signal.
Further, the bearing positioned in the middle of the supporting shaft is fixed on the supporting shaft through a clamping ring, and the bearing positioned at the end part of the supporting shaft is arranged in the handle cover groove.
Further, the handle cover is in interference fit with the handle roller.
Further, the support shaft is connected with the handle base through a first screw arranged along the axial direction.
Still further, the side of the support shaft is reinforced by a second screw disposed radially to the handle mount.
The handle operating mechanism based on the deviation switch has the advantages of being high in reliability, long in service life and low in cost.
Drawings
Fig. 1 is a schematic structural view of a handle operating mechanism based on a deviation switch.
Detailed Description
In order to better understand the technical solution of the present utility model, the following detailed description is given by way of specific examples:
referring to fig. 1, the handle operating mechanism based on a deviation switch of the present utility model includes a handle drum 1, a support shaft 2 and a handle base 3.
The handle operating mechanism is fixed at a set position and positioned at the side of the transmission belt through the handle seat 3. The support shaft 2 is connected to the handle base by means of a first screw 31 arranged in the axial direction. The side of the support shaft 2 is reinforced by the second screw 32 arranged along the radial direction to be connected with the handle seat, so that the support shaft 2 is prevented from relative displacement caused by loosening of the first screw 31 after long-term use.
The outer side of the support shaft 2 is sleeved with a handle roller 1, two ends of the handle roller are respectively provided with a handle cover 11, and the handle covers 11 are in interference fit with the handle roller 1.
Bearings are arranged at the handle cover positions on the two sides of the support shaft 2, a first bearing 21 positioned in the middle of the support shaft is fixed on the support shaft 2 through a clamping ring, and a second bearing 22 positioned at the end part of the support shaft 2 is arranged in the handle cover groove.
A cam micro switch (not shown) is arranged in the handle roller 1. When the conveyor belt is deflected, the handle roller 1 is driven to rotate after pressure is generated on the handle roller 1, and the cam micro switch is driven to rotate through the cam structure to send out signals when the handle roller rotates, so that the deflection signals can be sent out, and the deflection stroke and other functions can be calculated.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
