Problems solved by technology

[0002] Belt transportation is the main mode of transportation for coal and gangue in coal mines, but safety accidents at the tail of the belt conveyor emerge in endlessly, and the quality of belt conveyor drivers varies from unit to unit. The guardrail has a large gap and is placed at the tail of the machine casually. The fixation is not firm, it is easy to dump, and the safety factor is extremely low. When the belt conveyor tail winds coal, the belt conveyor driver can easily remove the guardrail to carry out Illegal cleaning operations, when the belt conveyor tail drum rolls coal, the cleaning operation is carried out without stopping the machine. Occasionally, there will be fatal accidents in the belt conveyor tail cleaning operation, and there will also be accidents that occur when the belt conveyor driver cleans up during the belt transportation process. This series of bloody accidents reminds us that we must improve the guardrail at the tail of the belt conveyor, so as to ensure normal safe production and long-term stability in the mining area.

Embodiment 1

[0041] see Figure 1-2 , the application provides a method for improving the emergency stop locking device for the tail of the belt machine, comprising the following steps:

[0042] S1. Adopt the first iron plate 8 and the second iron plate 9 with a thickness of 6mm respectively behind and above the tail drum 1 of the belt conveyor, and fix them on the tail frame 6 with bolts;

[0043] S2. On one side of the tail drum 1, use the screw hole on the tail frame 6 to process an emergency stop guard 2 with a curtain that can be opened up and down freely;

[0044] S3. Install a magnet 5 on the emergency stop guard plate 2, and then fix a magnetic sensor 7 at the junction of the guard plate and the tail frame 6. Using the principle of the magnet 5 and the magnetic sensor 7, the magnetic sensor The line of 7 is connected to the pull wire emergency stop of the belt conveyor;

[0045] S4. When the machine tail winds the coal for cleaning operation, set off the emergency stop guard 2 eq...

Embodiment 2

[0057] The difference from Example 1 is: the grip 4 is fixedly sleeved with a rubber handle, and the rubber handle includes the following raw materials in parts by weight: 20 parts of silicone rubber, 34 parts of reclaimed nitrile rubber, modified 15 parts of natural powder quartz, 26 parts of rice husk powder, 16 parts of sepiolite powder, 4 parts of hydroxymethylethylenediamine, 5 parts of dichloromethane, 4 parts of dialkyldioxysilane, 3 parts of zinc stearate, 5 parts of carnauba wax, 4 parts of butyl benzyl phthalate; The preparation method of described rubber grip comprises the following steps:

[0058] S101. Raw material preparation: prepare raw materials by weight, 20 parts of silicone rubber, 34 parts of nitrile reclaimed rubber, 15 parts of modified powdered quartz, 26 parts of rice husk powder, 16 parts of sepiolite powder, 4 parts of hydroxymethylethylenediamine 5 parts, 5 parts of dichloromethane, 4 parts of dialkyldioxysilane, 3 parts of zinc stearate, 5 parts of...

Abstract

The invention provides an improvement method of an emergency stop locking device for a belt conveyor tail, and belongs to the technical field of belt conveying. Comprising the following steps that S1, a first iron plate and a second iron plate which are 6 mm thick are adopted behind and above a belt conveyor tail roller correspondingly and fixed to a tail frame through bolts; s2, an emergency stop protection plate which is provided with a leaning curtain and can be freely opened up and down is machined on one side of the machine tail roller through a screw hole in a machine tail frame; and S3, a magnet is installed on the emergency stop protection plate, and then a magnetic sensor is fixedly installed at the joint of the protection plate and the machine tail frame. According to the improvement method, during cleaning operation, the magnetic sensor and the scram protection plate must be lifted, cleaning cannot be conducted without lifting, the belt conveyor can be shut down as long as the scram protection plate is lifted, the scram protection plate must be reset after cleaning is completed, the tail of the belt conveyor is kept in a totally-closed state, otherwise scram is not eliminated, and the belt conveyor cannot run, so that the safety effect is greatly improved.
