2.5m frequency conversion winch configuration scheme

　　Mine hoists rely on friction to lift heavy objects. They are generally used in large deep wells and mines with heavier lifting tonnages. According to the layout, they can be divided into: pit tower multi-rope friction hoist and floor-standing multi-rope friction hoist. Their structure is composed of a lifting container, a lifting wire rope, a friction wheel, a guide wheel (or sky wheel), and a tail rope.

　　During the operation of large construction machinery, corresponding supporting systems such as electrical control systems and signal control systems are needed. As the hoist electric control system for safe operation of mine hoists in mine production, master its correct operation method It is of great significance to the entire project production. Mine hoist is a kind of equipment mainly used in mines to achieve its working purpose by means of wire rope traction. The hoist manufacturer believes that it is mainly suitable for inclined roadways and small shafts on the ground or underground of coal mines, metal mines and non-metal mines. For such an important mining hoist in the heavy industry industry, we must do a good job in daily maintenance and maintenance.

　　1. Regular inspections. Regularly check the safety protection settings of the mine hoist;

　　2, the lifting container needs to be empty. During the rope adjustment operation of the double drum hoisting winch, the hoisting container must be empty. After the rope adjustment is completed, check the correctness of the interlock valve position, and the shut-off valve must be closed;

　　3, lower heavy objects, electric brake;

　　4. Keep the surface of the brake disc and brake shoe clean;

　　5. When replacing the brake shoes, the brake shoes must be replaced in groups, and the newly replaced brake shoes should be the same as the original brake shoes.

　　Maintenance work of mine hoist:

　　1. The operating environment should always be kept dry. Sichuan explosion-proof winches are sold. The surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.;

　　2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or overload or the setting value of the protection device is too low. After the fault is eliminated, it can be put into operation.

　　Mine hoists are widely used in mines. Because of their nature, they also play a more important role. However, in the process of use, mining hoists will inevitably not have some problems, except for problems. If the solution is resolved, the progress of the project will be delayed. A good way is to prevent these accidents in time. Let's take a look at how to do the maintenance of the mine hoist today!

　　1. The use environment should always be kept dry. Sichuan explosion-proof winches are sold. The surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.

　　2. When the thermal protection of the motor continues to operate, it should be ascertained whether the fault comes from the motor or overload or the setting value of the protection device is too low. After the fault is eliminated, it can be put into operation.

　　Mining hoist installation steps:

　　1. The mine hoist must be firmly installed on a solid concrete foundation. The surface of the foundation should be flat and horizontal to ensure that the mine hoist meets the vertical requirements after installation. A bucket elevator with a higher height should be connected to the adjacent buildings at the appropriate positions of the middle and upper casings to increase its stability. The hoist manufacturer prompts to install the lower parts first, fix the anchor bolts, and then install the middle casing, and then install the upper casing. The cabinet is installed successfully and the verticality is corrected. Measure with a straight line up and down the full height, the error should be less than 10. The upper and lower shafts should be parallel, and their axis should be in the same plane. When installing a bucket elevator with a lower height, the upper, middle and lower casings can be connected and aligned on the ground plane, and then the whole can be hoisted and fixed on the concrete foundation;

　　2. After the cabinet is installed, install the chain and hopper. The U-shaped screw used to connect the hopper is not only a chain joint, but also a fixing part of the hopper. The nut of the U-shaped screw must be tightened and reliably prevented from loosening;

　　3. After the chain and hopper are installed, they should be properly tensioned;

　　4. Add appropriate amount of oil and grease to the reducer and bearing seat respectively. The reducer is lubricated with industrial gear oil. Calcium-based or sodium-based butter can be used in the bearing seat;

　　5. Trial run. After the installation is completed, an empty test run should be carried out. Attention should be paid to dry running: no reverse rotation and no bumps. The idling operation is not less than 2 hours, there should be no overheating, the temperature rise of the bearing does not exceed 250C, and the temperature rise of the reducer does not exceed 300C. After 2 hours of idling, everything is normal and the load test can be carried out. Feeding should be even during the test run with load to prevent too much feed and block the lower part and cause "stuffy car".
