Port, wharf, etc.
1. Product details
PDB series break tape protector is the latest product developed and produced by Xuzhou Sanhuai Heavy Industry Equipment Co., LTD. The product is the domestic initiative, filled a gap in our country, simple installation, no maintenance, low rate of spare parts, widely used in mining, metallurgy, electric power, chemical industry, building materials. Port, wharf, etc. The belt breaking catcher is used as a roller under normal circumstances. When the belt is broken or the backstop fails, it can quickly catch the heavy and empty belt that suddenly slides down after the belt is broken (or out of control), and has the function of preventing the belt from running off. It can be used as a tape cassette when needed. It is mainly suitable for upward transportation of belt conveyor, especially suitable for large dip Angle, big Yunli, long distance uphill strong type or ordinary type belt conveyor.
2.Functional characteristics
The product is divided into upper and lower belt breaking catcher. Its characteristics are as follows: it adopts multi-point arrangement along the line to overcome the disadvantages of random changes of broken belt points.
The working mechanism adopts the form of local section braking, which can open the brake block mechanism.
It is triggered by contact with the belt, the trigger action is sensitive and reliable, and has the alarm function of broken belt (optional).
Adopt centrifugal claw no wear mode, long service life.
The product not only has the functions of broken tape, anti-deviation, failure protection of backstop, but also can be used as cassette device.
3. PDB series on the belt protector characteristics
Novel design, reasonable structure, sensitive action, safe and reliable
The disadvantages of random variation of broken belt points are overcome by using multi-point arrangement along the line. Working mechanism adopts local section brake, swing brake block mechanism, wide application range. Contact with the belt to trigger, trigger action is fast, sensitive, safe and reliable.
Centrifugal claw no wear operation mode, long service life
The product has many capabilities. In addition to the function of belt break, but also can be used as anti-deviation, check
4.PDBX series lower tape protector features
Split structure, flexible installation, convenient. Broken tape signal from the tape, accurate and reliable, so as to avoid misoperation.
To overcome the defect of random change of broken zone points, the arrangement along the line is adopted.
With the belt contact trigger mode, the action is sensitive and reliable.
Meet the random or regular test under continuous belt, to ensure the long-term operation of products, safe and reliable work. Easy to adjust, quick, sensitive action.
5. Structure principle of upper belt Breaking Arrester (DDZ)
Main structure principle: when the conveyor is working normally, the eccentric roller rotates concentrically with the operation of the belt, which is used as a normal roller. Once the conveyor breaks the belt or the backstop fails, the belt slides down, and the eccentric roller is eccentric under the action of the friction force of the belt. Reversal. When the eccentric roll reverses a certain Angle. Move the connecting rod mechanism to release the brake block above the eccentric roll. Due to the action of the eccentric roll, the gap between the brake I and the eccentric roll on both sides gradually becomes smaller, and the final torsional speed will capture the sliding heavy belt.
