Description

Technical Field

[0001] The utility model belongs to the technical field of sensor fixing equipment, and in particular relates to a sensor installation device for a belt conveyor. Background Art

[0002] According to the relevant provisions of the "Coal Mine Safety Regulations", GB10595-"Technical Conditions for Belt Conveyors", GB14784-93 "Safety Specifications for Belt Conveyors", MT820-"Technical Conditions for Belt Conveyors for Coal Mines", MT654-1997 "Safety Specifications for Belt Conveyors for Coal Mines", MT872-"Technical Conditions for Protective Devices of Belt Conveyors for Coal Mines", etc., the deviation protection of belt conveyors should be used in pairs, and one group should be installed at the head and tail of the machine. When the belt conveyor has a slope change, one group should be installed at the slope change position. The deviation protection should be fixed on the longitudinal beam of the belt conveyor using a special bracket to protect the deviation of the belt on the belt conveyor. The installation standard is: when the running conveyor belt deviates by 20mm beyond the edge of the roller, such as more than 70mm for a belt conveyor using triple rollers, the deviation protection device should alarm; when the running conveyor belt exceeds the roller by 20mm, such as more than 70mm for a belt conveyor using triple rollers, after a delay of 5-15S, the deviation protection device should operate reliably and interrupt the operation of the belt conveyor;

[0003] The function of the deviation protection means that when the belt deviates from its original direction, the conveyor belt will hit the protection bar of the deviation protection, and the protection bar will drive the relevant components in the sensor body to control the belt conveyor to alarm or shut down; in actual application, if this deviation protection is installed on the outside of the longitudinal beam mark, the aforementioned 20mm standard will be exceeded, which is a major hidden danger, so it is usually installed on the inside of the longitudinal beam rod, but the space on the inside is limited and installation is inconvenient.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A sensor installation device for a belt conveyor, comprising a clamping card, a longitudinal support rod, a transverse support rod, a diagonal support plate, a sensor and a protection rod. The clamping card is fixedly arranged on the longitudinal beam rods on both sides of the belt conveyor through bolts. The longitudinal support rod is vertically and fixedly arranged at the upper end of the clamping card. The transverse support rod is an L-shaped channel steel, and one end is horizontally fixedly arranged on the upper part of the longitudinal support rod. A long strip-shaped first adjustment screw hole in the front-back direction is formed on the top surface of the other end of the transverse support rod. The diagonal support plate is in a "乁" shape structure, and the top surface is arranged on the transverse support rod through bolts and the first adjustment screw hole. Long strip-shaped second adjustment screw holes are vertically formed around the diagonal support plate. The sensor is arranged on the diagonal support plate through bolts and the second adjustment screw holes. The protection rod is arranged at the lower end of the sensor, and the lower end of the protection rod is located on one side of the conveyor belt.

[0007] Further, the horizontal distance between the lower end of the protection rod and the edge of the idler is less than or equal to 20 mm.

[0017] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As Figure 1-4 shown, a sensor mounting device for a belt conveyor includes a clamping clip 4, a longitudinal support rod 5, a transverse support rod 6, an inclined support plate 8, a sensor 9, and a protection rod 10. The clamping clip 4 is fixedly arranged on the longitudinal beam rods 1 on both sides of the belt conveyor by bolts. The longitudinal support rod 5 is vertically and fixedly arranged at the upper end of the clamping clip 4. The transverse support rod 6 is an L-shaped channel steel, one end of which is horizontally and fixedly arranged on the upper part of the longitudinal support rod 5. A long strip-shaped first adjustment screw hole 7 in the front-back direction is opened on the top surface of the other end of the transverse support rod 6. The inclined support plate 8 is in a "乁"-shaped structure, and the top surface is arranged on the transverse support rod 6 through bolts and the first adjustment screw hole 7. The included angle α between the inclined support plate 8 and the horizontal direction satisfies 60° ≤ α ≤ 90°. Long strip-shaped second adjustment screw holes 11 are vertically opened around the inclined support plate 8. The sensor 9 is arranged on the inclined support plate 8 through bolts and the second adjustment screw holes 11. The protection rod 10 is arranged at the lower end of the sensor 9. The lower end of the protection rod 10 is located on one side of the conveyor belt 3, and the horizontal distance from the edge of the idler 2 is less than or equal to 20 mm.

[0019] The working process of the present utility model:

[0020] One set of the device of the present utility model is installed on the longitudinal beam rods 1 at both the head, tail, and middle of the belt conveyor. The sensor 9 is electrically connected to the alarm device through a controller. When the belt conveyor operates for a period of time and the conveyor belt deviates, when the edge of the conveyor belt contacts the protection rod 10 and generates a force on the protection rod 10, the protection rod 10 triggers relevant components in the sensor 9, sends a danger signal to the controller, and then the controller controls the alarm system to issue an alarm. When the conveyor belt deviates from the idler 2 by 20 mm or more, the controller controls the belt conveyor to stop to prevent accidents.

[0021] During use, if the position of the protection rod 10 is inappropriate, the lateral adjustment of the inclined support plate 8, the sensor 9, and the protection rod 10 can be realized by adjusting the position of the bolt in the first adjustment screw hole 7, and the longitudinal adjustment of the sensor 9 and the protection rod 10 can be realized by adjusting the position of the bolt in the second adjustment screw hole 11.
