The belt conveyor is mainly composed of several parts which? What is the role?

The transmission principle of the belt conveyor is continuous conveying machine to transport with a traction mechanism, the rubber belt wrapped in the drive roller, roller conveyor belt and rely on friction to drive the tape running. Is mainly composed of a machine head, a body part, and the tail of the rubber conveyor belt, etc.. Motor, hydraulic coupling, reducer, main and auxiliary driving drum and unloading arm composed of nylon belt conveyor head. The motor to provide power, hydraulic coupler to equalize the motor load, improve the motor starting performance. The unloading arm is mainly used to uninstall, uninstall the drum to prevent belt deviation in a certain range. Reducer is used to reduce the speed of the motor, the motor is transmitted torque to the transmission roller, increase the torque through the reducer, belt conveyor body with a hanging type and floor type. Part of the rope frame middle frame hanging type: middle frame, H shaped upper and lower roller, hook, rope, elastic rope, support. Part of floor type middle frame: H shaped middle frame, beam, elastic cylindrical pin, upper and lower roller, roller connector. For supporting roller conveyor belt, nylon conveyor belt to reduce running resistance, and make the canvas belt sag does not exceed a certain limit, in order to ensure the smooth operation of conveyor belt. Divided by use of trough type roller, parallel roller, self-aligning roller and buffer roller four.Rubber conveyor belt conveyor belt to bypass the series tail tail roller changing running direction, and the loading of coal continuously transported to the unloading machine head.

The operator procedure of belt conveyor are those?

The inspection items and requirements should drive the screw bolt: complete fastening; sweeper sweeper is complete, and the conveying belt distance not greater than 2 to 3 mm, and sufficient pressure, the contact length should be more than 85%; stand firm and reliable connection, head, tail firmly fixed; the roller is complete, and the center line of the vertical belt conveyor; conveyor belt tension; belt joints straight, oil level, oil and oil seal qualification; must comply with the requirements of communication, signal; system reliability failure; various protection devices, sensitive and reliable;

The start-up operation: must obtain a signal contact with the head, tail and the loading point before the start, to receive the correct signal, all the staff leave the rotating parts before boot; note the conveyor belt is running, the temperature, the sound is normal; ensure all roller rotate flexibly, head, tail and no coal, float coal; the operator left the post to cut off the power supply; before shutdown, should be on the conveyor belt to pull the empty coal.

The belt conveyor running attention is what?

1, operation process:

The scene, ask succession, check the surrounding environment. The hand control switch to off position and lock up, then the power card, driving device, cleaning device, hydraulic coupler, roller, belt joint, spillplate, signal and all kinds of protective equipment and dust removal facilities to conduct a comprehensive inspection, found the problem of processing. Second, boot, control switch card, remove the power control switch, a driving signal to move two times, turn again for more than a week, and then check the following items: the sound operation is normal, delivery with no deviation, slipping and appropriateness of elastic, control button, signal and other facilities are sensitive and reliable. Complete the examination, treatment before formal operation.

Third, shift, belt conveyor and coal clean, clean environment, cut off the power supply, close the dust removal facilities, site and fill in the shift operation log.

2, matters needing attention:

The driver must confirm the signal, according to the provisions of signal starting and stopping conveyor.

Second, no overload start forcibly, and avoid frequent start. No person shall take the conveyor, or the use of conveyor transport equipment and heavy materials.

Third, in the process of operation, pay attention to operating conditions, check operation, roller conveyor belt deviation, conveying belt tension, cleaning device, speed reducer, hydraulic coupling has no leakage, lubrication, reducer, hydraulic coupling, electric machine and all roller bearing temperature is normal. Listen, the various parts of the sound.

The conveyor belt running, coal cleaning prohibited head and tail roller and its nearby, not to pull the conveying belt cleaner.

The move, driving and handling conveyor belt deviation, prohibit the use of hands and feet, directly touch the conveyor belt.

The prohibition of the use of unqualified, fusible plug, explosion or substitute.

The scene quickly adjust the transport belt deviation method is what?

The automatic deviation adjusting roller, when the belt deviation is small, the maximum belt deviation, install self-aligning roller.

The unilateral vertical roller conveyor belt offset, always to the side of the deviation, deviation in the side of the deviation range is added with a plurality of vertical roller of the conveyer belt reset.

Appropriate tension adjustment, when the belt deviation huzuohuyou, direction from time to time, that the conveyor belt is too loose, may be appropriate to adjust the tensioning device to eliminate the deviation.

The offset adjustment roller, belt conveyor in the drum, the drum check is abnormal or movement, the normal rotation rollers to adjust the horizontal position, eliminate the deviation.

Offset correction and conveying belt joint, belt conveyor is always in one direction, and the maximum deviation in the joints, adjustable conveyor belt joint and vertical conveying belt line, to eliminate the deviation.

The pad roll gauto offset, belt conveyor direction, distance, can be run in the direction of the contralateral pad and gauto a number of groups, to eliminate the deviation.

The adjustment roller adjusting, belt conveyor direction, found roller center line and belt center line is not vertical, you can adjust the roller, eliminate the deviation.

The elimination of slime offset, the belt deviation remains constant, found the supporting rollers in adhesive slime, should eliminate slime offset.

To feed offset correction, conveyor belt light load without deviation, heavy load deviation, can be adjusted to the weight of material and position, eliminate the deviation.

The offset correction bracket, belt deviation direction, fixed position, serious deviation, adjustable bracket level and verticality, eliminate the deviation.
