JYB-S two-speed transport winch

JYB-S two-speed transport winch is a patented product independently developed and designed by our company. The patent number is ZL201721592933.X. Two - speed transport winch is divided into full hydraulic type and semi - hydraulic type. The two-speed transport winch is suitable for pulling car and other auxiliary transport in roadway with dip Angle less than 30°, but not suitable for lifting.

The two-speed transport winch consists of a motor, a planetary differential, a fast and slow speed variable speed brake, a drum, a final planetary transmission device, a working brake, a safety brake, a depth indicator, a base, a hydraulic station and an electronic control system.

Have the following characteristics

① The winch can achieve two speed changes to meet the requirements of speed and torque of different materials and different roadway conditions.
② Fast and slow speed regulating gate for the use of spring pressure normally open structure type of hydraulic gate, through the operation of manual reversing valve and proportional pressure regulating valve control, easy to operate and labor saving, greatly reduce the labor intensity of workers.
(3) The safety brake is a normally closed hydraulic brake with spring pressure. The brake is normally open when working normally. If abnormal conditions occur, the electromagnetic reversing valve can be controlled by the operation of the control button to realize rapid emergency braking, which is safe and reliable.
(4) The working brake is a normally closed hydraulic brake with spring pressure. The brake can be realized and released by manipulating the proportional pressure regulating valve during normal operation.
⑤ Solve the common transport winch for a long time brake effort, and can not be reliable braking, workers labor intensity defects.

Electric control device and leakage communication system are optional for winch

Leaky communication system

The winch is equipped with a leakage mobile communication system, which can realize the functions of hitting, calling, emergency stop and locking. The system has strong anti-interference ability, the whole network call clear, reliable quality, a variety of valid documents complete. Leakage communication system equipment mainly includes: communication/signal base station, base power supply, leakage cable, handheld, terminal junction box, etc. The leakage communication is connected with the special electronic control system of the winch, which can realize the function of the leakage communication device to stop the main engine of the winch, and improve the safety of the winch operation.

Special electric control device for winch

The electric control part has parameter display and monitoring, relative running distance, display of the running position of the tractor, dynamic digital display of the distance from the tractor to the main motor, (up, down, stop, reset, etc.) operation status display, and control system parameters (voltage, current, frequency, working time, current time, etc.) display. The electric control part has conventional protection (overcurrent, overvoltage, undervoltage, short circuit, overload, short phase overheating, etc.), special protection (over winding, over discharge, overspeed, underspeed, functional element overheating, etc.), and fault memory functions. The special electric control device for the winch is equipped with a voice, sound, and light alarm device for mining, which can achieve the warning of "driving, no pedestrians" along the roadway when the winch is running, improving the safety of the winch operation.
