Under speed protection device and blocking switch are added to the circuit system of bucket elevator

Article source: admin release date: May 25, 2020

Under speed protection device and blocking switch are added to the circuit system of bucket elevator. The main body of the device is cylindrical, with a cavity inside, which is equipped with current transformer, printed circuit board, etc. There are two lead-in cables, one is the lead-in cable for detection sensor, the other is the power supply and output contact cable. The sample detection device is a coil, which is installed in a rectangular plastic box of the same shape. The sampling coil is placed in an iron chute, and the outgoing cable of the sampling coil is connected into the main body of the protection device.

stay Bucket elevator A probe rod with magnetic steel is installed in the middle of the hoist which swings automatically with the operation of the hoist. When the bucket elevator is running, the magnetic steel will sweep from the top of the coil regularly. Every time the magnetic steel sweeps through the coil, a pulse signal will be generated on the coil. Under speed protection measures the time interval between two signals, and then calculates its under speed value. When the under speed reaches the set value, the relay acts, the contact is disconnected, and the bucket elevator stops running and is protected.

The bucket elevator has low driving power, and adopts inflow feeding, induced discharge and dense hopper layout with large capacity;

Bucket elevator products are suitable for lifting from low to high. After the materials are put into the hopper through the vibration table, the machine will automatically and continuously move upward. According to the transmission capacity, the transmission speed and lifting height can be selected as required.

 Bucket elevator

1. The bucket elevator shall be equipped with winch limiter and travel limiter, which shall make the pulley stop automatically when it is lifted to 300 mm away from the drum or pulley.

2. The hoist is not allowed to carry people up and down.

3. The bucket elevator can be adjusted according to the transmission capacity. The bucket elevator should be marked with heavy load, and the weight should not be overloaded during lifting and landing.

4. Keep the environment around the elevator clean.

5. After power transmission, check the safety devices such as winch limiter, travel limit device, interlock switch, etc., and conduct trial lifting.

6. Before lifting and landing, the car can be started only after the bell is sounded for warning.

7. After the work is finished, the hoisting plate of the hoist shall be on the ground, and then the power supply shall be cut off,

It has the advantages of advanced, reliable, easy to use, easy to use and easy to use. High lifting height. The elevator runs smoothly, so it can reach a higher lifting height; its service life is long, the feeding of the elevator adopts the inflow type, and there is no need to dig the material with a bucket, so there is little extrusion and collision between the materials.

With wide lifting range, this kind of hoist has less requirements on the types and characteristics of materials. It can not only improve the general powder and small granular materials, but also can improve the materials with high grinding performance, good sealing performance and less environmental pollution. It has good operation reliability, advanced design principles and processing methods, which ensure the reliability of the whole machine.
