Abstract
The utility model discloses a JKMD type mine hoist with a brake torque monitoring function. The JKMD type mine hoist is composed of a motor, a hoist rotary drum, a disc type braking system and a brake torque monitoring device; the brake torque monitoring device is composed of a pressure sensor, a signal transmitter, a PLC (Programmable Logic Controller) and a displayer which are electrically connected; the pressure sensor is embedded in an oil cylinder of the disc type braking system and is used for transmitting a pressure signal of the oil cylinder to the PLC; and then the oil pressure in the oil cylinder is monitored at any time through the displayer. As the mine hoist is provided with the brake torque monitoring device, the brake torque of a disc-type brake can be accurately monitored, and when the brake torque is not in a specified range, an alerting signal can be given out, thereby providing scientific basis for maintenance personnel to adjust the closing gap of braking oil pressure, taking preventive measures and ensuring the safety operation of the hoist.
Description
Technical field
The utility model relates to JKMD type mine hoist.
Background technology
JKMD type mine hoist is that the colliery is carried the people, carries thing and carried the important equipment of coal, is on the connection well of colliery, the important channel of down-hole.It is made up of electrical motor, elevator drum and disk braking system.Disk braking system is the important safety fender guard of gig; It is as last link of mine hoist safety protection; Be normal ramp to stop of mine hoisting system and the final means of under various lifting failure conditions, implementing hard brake stop; Be the important safety that guarantees the mine hoist safety operation, whether lock torque and brake acjustment be reasonable, directly influences the safe operation of gig.
Previously used JKMD type mine hoist has only brake block abrasion monitoring and spring fatigue monitoring, does not have special lock torque monitoring, and there is certain potential safety hazard in the size of brake monitoring moment constantly.
Summary of the invention
The utility model be overcome above-mentioned gig braking system many deficiencies, it is improved, a kind of JKMD type mine hoist of safety and reliability is provided.
A kind of JKMD type mine hoist with lock torque monitoring, it is made up of electrical motor, elevator drum and disk braking system, it is characterized in that, and it also comprises the lock torque monitoring device; The lock torque monitoring device is electrically connected by pressure sensor, signal transmitting device, PLC Programmable Logic Controller and telltale to be formed; Pressure sensor is pre-buried in the oil cylinder of disk braking system; The oil cylinder working-pressure signal is sent to the PLC Programmable Logic Controller, monitors in-oil cylinder oil pressure at any time through telltale again.
This mine hoist is owing to be provided with the lock torque monitoring device; The lock torque that can correct monitoring goes out disk brake; When lock torque does not provide alerting signal during the scope in regulation; For service personnel adjustment braking oil pressure combined floodgate gap provides scientific basis, take preventive measures, guarantee the safe operation of gig.
Description of drawings
Fig. 1 is the scheme drawing of the utility model embodiment, and the installation situation of pressure sensor has been shown among the figure.
Marginal data, 1-electrical motor, 2-elevator drum, 3-oil cylinder, 4-pressure sensor, 5-signal transmitting device, 6-PLC Programmable Logic Controller, 7-telltale.
The specific embodiment
JKMD type mine hoist with lock torque monitoring as shown in Figure 1, it is made up of electrical motor 1, elevator drum 2, disk braking system and lock torque monitoring device; The lock torque monitoring device is electrically connected by pressure sensor 4, signal transmitting device 5, PLC Programmable Logic Controller 6 and telltale 7 to be formed; Pressure sensor 4 is pre-buried in the oil cylinder 3 of disk braking system; Oil cylinder 3 pressure signals are sent to PLC Programmable Logic Controller 6, monitor the oil pressure in the oil cylinder 3 at any time through telltale 7 again.
