Detailed Description

The utility model relates to a dust explosion-proof two-stage deviation switch protection device for a belt conveyor, which comprises a base 1 for accommodating components, wherein the base 1 is rectangular and is internally provided with a cavity, a control assembly capable of playing a control role is arranged in the cavity, an upper cover 2 connected with the base 1 through a bolt for playing a protection role is arranged right above the base, and positioning blocks 3 fixedly connected with the base 1 and used for mounting the bolt are symmetrically arranged on two sides of the base along the axis.

As shown in fig. 1-3, outlets 4 fixedly connected to the base 1 for providing a guiding function are provided at two sides of the upper portion of the base 1, and a handle 5 for a user to dial is provided at one side of the base 1.

As shown in fig. 1-3, the control assembly includes a shaft 6 disposed inside the base 1 and connected to a rotating shaft thereof for transmitting a driving force, and one end of the shaft 6 is fixed to the handle 5 by a bolt.

As shown in fig. 1-3, the fixing device further comprises a main connecting plate 7 arranged in the middle inside the base 1 and used for limiting, connecting columns 8 connected with the main connecting plate 7 through threads are symmetrically arranged on one side of the main connecting plate 7 and used for connecting, an auxiliary connecting plate 9 connected with the connecting columns 8 through threads and used for fixing is arranged on one side of the connecting columns 8, and one side of the auxiliary connecting plate 9 is fixed to the base 1 through bolts.

As shown in fig. 1-3, the device further comprises spring covers 10 which are symmetrically arranged on two sides of the main connecting plate 7 and connected with each other through a stud for limiting, and a torsion spring 11 capable of generating torsion is arranged between the spring covers 10.

As shown in fig. 1 to 3, the outer surface of the spring cover 10 is provided with an inner connecting member 12 for restriction, and the outer side of the inner connecting member 12 is provided with an outer connecting member 13 for restriction.

When a user uses the deviation switch protection device manufactured by the utility model, the deviation switch protection device is fixed on the machine frames at the two sides of the belt conveyor, the axis of the handle 5 is vertical to the surface of the rubber belt sheet, the distance between the vertical stick and the edge of the rubber belt is 50 mm-100 mm, the rubber belt is positioned at the 1/3 position at the lower end of the handle 5, when the adhesive tape deviates, the edge of the adhesive tape drives the handle 5 to rotate and squeezes the handle 5 to incline, the handle 5 will drive the shaft rod 6 to rotate synchronously, and the shaft rod 6 will drive the inner connecting piece 12 and the outer connecting piece 13 to move along with the rotation, the inner connecting piece 12 and the outer connecting piece 13 drive the torsion spring 11 to twist, and the torsion spring 11 stores the force, and then the alarm device is pulled by a steel wire rope preset at the wire outlet 4 to carry out alarm operation, so as to prompt a user that the belt deviates.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes in the features and embodiments, or equivalent substitutions may be made therein by those skilled in the art without departing from the spirit and scope of the utility model. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the utility model without departing from the essential scope thereof. Therefore, it is intended that the utility model not be limited to the particular embodiment disclosed, but that the utility model will include all embodiments falling within the scope of the appended claims.
