Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
As shown in fig. 1 and fig. 2, in this embodiment, a coal conveying belt non-contact leakage-detecting type tearing protection alarm device is provided, which includes a transverse support bar 2, a material collector 6, a balance spring 7 and a travel switch 8, wherein the material collector 6 is disposed under the coal conveying belt along a direction parallel to the running direction of the coal conveying belt, the lower surface of the material collector 6 is fixed with the transverse support bar 2 parallel to the material collector, two ends of the transverse support bar 2 are respectively connected to two cross beams for supporting the coal conveying belt through a fixed bearing 1, two sides of the material collector 6 parallel to the running direction of the coal conveying belt are respectively provided with the balance spring 7 and a counterweight component, the balance spring 7 extends vertically and downwardly, one end of the balance spring 7 is connected to the material collector 6, the other end is fixedly connected to the corresponding cross beam, the counterweight component includes a longitudinal balance bar 4 and an adjusting flange 3 disposed on the longitudinal balance bar 4, the longitudinal balance bar 4 protrudes and extends outwards along the direction perpendicular to the transverse supporting bar 2, the adjusting flange 3 can reciprocate along the extending direction of the longitudinal balance bar 4, and the travel switch 8 is fixed on the cross beam.
In this embodiment, the number of balance springs 7 and the number of counterweight assemblies can be set according to actual conditions, so as to better satisfy actual requirements. Referring to fig. 1, the number of the balance springs 7 and the balance weight assemblies is two.
In this embodiment, the longitudinal balance bar 4 is provided with a thread, the adjusting flange 3 is provided with a fixing nut 5 coaxial with the adjusting flange, and the fixing nut 5 is engaged with the longitudinal balance bar 4 to fix the adjusting flange 3 on the longitudinal balance bar 4.
The adjusting flange 3 plays a role of a balance weight, the fixing nut 5 is used for being meshed with the longitudinal balance rod 4 and can move on the longitudinal balance rod 4 in a reciprocating mode, the position of the adjusting flange 3 relative to the longitudinal balance rod 4 is changed, and the coal conveying belt is guaranteed to be not torn, and the material collector 6 is in a balance state.
In this embodiment, the side of the material collector 6 provided with the balance spring 7 extends obliquely upward to form an oblique baffle 9.
Baffle 9 extends in the tilt up, can guarantee when coal conveyor belt tears, and the material on the coal conveyor belt falls on loading head 6 more smoothly, thereby avoids the material because vibration effect directly from loading head 6 gliding influence loading head 6 oppression balance spring 7, and then influence travel switch 8's triggering.
