Description

Device for improving safety coefficient of stroke position of hoisting system

Technical Field

The utility model belongs to the technical field of the metallurgical equipment, concretely relates to promote device of hoist system stroke position factor of safety.

Background

The winch is widely applied to industries such as metallurgy, building, mine and the like as a conveying device, and due to the large scale of the metallurgy industry, the transportation stability of materials meets the reliable requirement, and the winch also needs to be fast, stable and accurately stopped in the transportation process. The traditional winch control generally adopts the speed reducer side to install a master controller additionally and combines a position encoder to control the operation of the skip car, and the skip car position can only be detected by depending on the side rotation of the speed reducer. The detection is unreliable, the number of fault points is large, and production accidents are easily caused by shutdown after the detection device breaks down.

What blast furnace ironmaking needs is a continuous, lasting stable operational environment, blast furnace charging system is as the core equipment of blast furnace, whether the blast furnace can normal production has directly been decided to the stability of raw materials transport, blast furnace main hoist engine is the main conveying equipment of blast furnace raw materials for production, large-scale blast furnace conveys raw materials and reaches dozens of tons each time, in the process of the high-speed operation to shutting down of hoist, need reliably detect the skip position and reach accurate parking mesh, in case detection device body is bad or skip stroke position detects the mistake, the skip is out of control and very easily causes the severe accidents such as skip dashes the top, arrange the material in disorder.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a promote device of hoist system stroke position factor of safety, the safeguard measure effect is more direct, safe and reliable.

The utility model discloses a realize through following technical scheme:

the utility model provides a promote device of hoist system stroke position factor of safety, includes the hoist engine, the hoist engine includes the cylinder, the both sides of cylinder are equipped with the speed reducer, are equipped with hoist stroke encoder on the speed reducer of one side wherein, set up more than one count probe on the cylinder wheel edge that the speed reducer of opposite side corresponds, the count probe links to each other with count processing module, count processing module links to each other with autonomous system.

Preferably, the number of the counting probes is more than 3.

Preferably, the counting probe is an infrared probe.

Preferably, the automatic control system adopts a PLC system.

The utility model has the advantages as follows:

at least 3 counting probes are additionally arranged at the side position of the winch roller, the actual running circle number of the winch roller is detected through the probes, three detected circle values are collected and compared with the set parking circle number value, when at least two detected data values are equal to the set value, the system outputs a parking instruction to control the skip car to park, and therefore the winch is protected to park. The utility model discloses a position that direct detection hoist engine cylinder actually rotated is handled through backstage count processing module and is finally sent the parking instruction, and the safeguard measure effect is more direct, safe and reliable.

Drawings

FIG. 1 is a schematic structural diagram of a device for increasing the safety factor of a hoisting system in a stroke position;

in the figure: 1. a drum; 2. a speed reducer; 3. a winding stroke encoder; 4. counting the probes; 5. a counting processing module; 6. an automatic control system.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1

The utility model provides a promote device of hoist system stroke position factor of safety, is shown in figure 1, including the hoist engine, the hoist engine includes cylinder 1, the both sides of cylinder 1 are equipped with speed reducer 2, are equipped with hoist stroke encoder 3 on the speed reducer 2 of one side wherein, set up more than one count probe 4 on the cylinder 1 wheel limit that speed reducer 2 of opposite side corresponds, count probe 4 links to each other with count processing module 5, count processing module 5 links to each other with autonomous system 6. The counting probe 4 can adopt an infrared probe, and the automatic control system 6 can adopt a PLC system.

In this embodiment, the number of the counting probes 4 is 3, which are respectively marked with C1, C2 and C3, and are used for counting when the winch is running, transmitting the collected data to the counting processing module 5 for data collection processing, and finally transmitting the processing operation result signal to the automatic control system 6. The counting processing module 5 simultaneously calculates the three collected signals C1, C2 and C3, when any two values of three groups of data C1, C2 and C3 are equal to a set value of the number of winding running circles (namely a parking set circle value), the counting processing module 5 outputs a processing signal for protecting the position stroke of the winding system and sends the signal to the automatic control system 6, and the automatic control system 6 outputs a parking instruction to control the skip car to park, so that the winding machine is protected to park.
