Introduction of jtp1.2 × 1.0p hoisting winch

   Hoisting gear All post workers must work with certificates and operate in strict accordance with the operating procedures; this work must be assigned personnel, posts, and responsibilities, and the main mechanical and electrical person in charge must be on-site supervision and command. Special personnel shall be assigned to be responsible for unified command at the construction site.

Before each construction, special personnel shall be assigned to inspect the mechanical, braking and electrical parts of the hoist to ensure reliability; before construction, special personnel shall be assigned to conduct detailed inspection on the signal communication system to ensure that it is clear, smooth and reliable; during the construction, the hooker on the shaft is responsible for placing warning in the well shed, and it is strictly forbidden for miscellaneous personnel to play in the shed. The underground signalman is responsible for setting out the warning within 20 m of the South and North Wharf gate of the lower wellhead. No one is allowed to watch up, stay and make noise or walk through the shaft;

During the rope withdrawal period of the hoisting winch, a special person shall be assigned to observe the stress condition of the clamp at the crown wheel platform. If any abnormality is found, the winch room shall be immediately informed to stop. Special personnel shall be assigned to set off the hoisting steel wire rope outside the winch room. If any abnormal situation is found, it shall be immediately notified to stop. All personnel participating in the test shall not drink alcohol before and during the shift, and shall concentrate their energy and obey unified command and management;

Before each use of steel wire rope and sliding rope, special personnel shall be assigned to check to ensure that they are in good condition; when the cage is running to the upper and lower wellhead, and the cage at the wellhead and the cage at the bottom of the well are ready to fall on the support cage seat, the signal worker on the underground well shall contact the signal worker on the well, and the signal worker on the well shall transmit the point to the winch room; When climbing on the edge of the shaft or the crown wheel platform, the staff must wear qualified belt and take root firmly, and the tools carried must be added with slip rope;

When lifting the seamless pipe and lifting the coil of steel wire rope, we should make concerted efforts to prevent the phenomenon of bumping, crushing and hurting people. In particular, when passing pipes under the cage, the construction personnel shall concentrate, obey the unified command, put the seamless pipe under the cage and fix it; the tools carried by the operators of the crown wheel platform must be tied with tail rope and take root reliably to prevent falling objects in the shaft. When locking rope of crown wheel platform, the steel wire rope must be lined with slide belt or other hard plastic. Special personnel shall be assigned to inspect the rope locking of the crown wheel platform, and the rope clip shall be firmly fixed, and one clip shall be clamped with splint;

In the mine, the life support of mine hoist is indispensable in the mine production line. In the braking system of JK mine hoist, adjustable brake is its lifeline, which is the guarantee of mine hoist operation.

The adjustable brake is a set of hydraulic mechanical brake system controlled by electricity, which is a protective measure to enhance the operation. Therefore, the control of the brake system must be reliable. The brake control system is usually controlled by the driver, and is often called the brake control system. Working brake is used as a normal parking or ordering means in manual operation or automatic operation mode. However, when the system fails, the hoist will slow down and stop quickly in the running state, and the brake cannot be released in the static state.

Braking is divided into braking and secondary braking. When the lifting container is in the shaft and far away from the parking point, if the system fails and needs emergency braking, the secondary braking should be adopted. The so-called secondary braking is that the braking torque is not added to the brake disc at one time, but divided into two times, so that the deceleration during emergency braking is relatively small, the deceleration is relatively slow, and the damage to mechanical equipment is small. The container needs to slide for a distance before stopping after emergency braking. When the brake is close to the wellbore, the brake should be used when it is close to the emergency stop point. When braking, the braking torque is large and the sliding distance is short in emergency braking. At present, the hoists of * * are equipped with brake devices with adjustable braking force.
The technical performance of hoist electric control system will directly affect the efficiency of mine production. Once one of them fails, the control system will stop working. Therefore, the operation of hoist control system is very important.
