Description

Technical Field

[0001] The present application relates to the technical field of temperature measurement of belt conveyor rollers, and in particular to a fixture for temperature measurement of open belt conveyor rollers. Background Art

[0002] Belt conveyors are equipment used to transport materials. They are indispensable equipment in many industrial production links, especially in some harsh production environments. They are often subject to vibration loads and impact loads, which cause serious wear and tear on the belt conveyor rollers.

[0003] In the prior art, such as Figure 1 As shown, the belt conveyor is provided with a support group for supporting the belt and making it V-shaped and a return roller 16 for supporting the return of the belt. The support group includes a support roller 15 and diagonal support rollers 14 located on both sides of the support roller 15. The return roller 16 and the support roller 15 are both in a horizontal state.

[0004] When multiple rollers run for a long time, they will generate heat due to friction, which will easily have an adverse effect on the operation of the belt conveyor over time. It is necessary to monitor the operating temperature of the rollers in real time to ensure the safe operation of the belt conveyor. Temperature measurement requires the use of optical fiber for data transmission. The existing belt conveyor roller temperature measurement optical fiber clamp cannot effectively fix the optical fiber, the structural compliance is poor, which reduces the accuracy of monitoring, and is easy to cause optical fiber damage. The installation is not convenient, thereby reducing the detection effect of the roller temperature. Utility Model Content

The box body 21 is provided with a card slot 25 for the diagonal support roller 14 to be placed. The box body 22 is buckled on the inner wall of the box body 21 for positioning and the two form a closed placement space 24. The box body 21 is against the first bracket 11 and is clamped with one end of the diagonal support roller 14 through the card slot 25 for positioning. The diagonal support roller 14 passes through the card slot 25 and extends into the placement space 24; a plurality of clamping pieces 23 are fixedly mounted on the side wall of the box body 21 close to the box body 22.

A truncated cone-shaped positioning head 36 is coaxially fixedly installed on the pressing screw 32. The diameter of the positioning head 36 close to the pressing screw 32 is smaller than the diameter of the positioning head 36 away from the pressing screw 32, thereby increasing the contact area between the box body 22; the pressing screw 32 pushes the positioning head 36 to press against the positioning groove 35 for positioning.
