Description

Technical Field

[0001] The utility model relates to the technical field of hoists, in particular to a laser type tail rope track real-time monitoring device. Background Art

[0002] The tail rope is an important component of the multi-rope friction wheel hoist in the coal mine shaft. During the operation of the hoist, the hoisting head rope will be responsible for bearing the weight and lifting force of the materials, while the tail rope needs to bear the opposite force generated by gravity. If there is no tail rope, the tension of the hoisting rope will be unbalanced, resulting in unstable lifting. The tail rope can not only balance the tension of the hoisting rope, but also maintain the overall balance of the hoist. When the hoist is working, due to the different weights of the materials carried, the tension of the hoisting head rope will also be different, causing the hoist to be unbalanced. The existence of the tail rope can keep the hoist in a horizontal state at all times to prevent the occurrence of unbalanced lifting.

[0003] At present, in order to ensure the normal operation of the tail rope, a camera is generally installed at the tail rope guard beam, and the driver monitors the running trajectory of the tail rope through video. If an emergency occurs but the driver fails to discover it in time, the tail rope may be damaged or fall, resulting in serious consequences. Therefore, the utility model proposes a laser tail rope trajectory real-time monitoring device to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes a laser tail rope trajectory real-time monitoring device, which is convenient for real-time monitoring and prompts the driver to take corresponding measures to avoid the occurrence and expansion of accidents.

[0006] The laser detection assembly includes a laser generator and a laser receiver. The laser generator is located at the front end position above the support frame, and the laser receiver is located at the rear end position above the support frame. A laser is connected between the laser generator and the laser receiver, and the signal output end of the laser receiver is electrically connected to the sound and light alarm.

[0007] A further improvement is that the sound and light alarm is connected to a timer, and the timer is used to count down the alarm of the sound and light alarm.

[0008] A further improvement is that: the front and rear ends of the top of the support frame are both provided with mounting rods, the laser generator is arranged on the mounting rod at the front end, and the laser receiver is arranged on the mounting rod at the rear end.

[0009] A further improvement is that an L-shaped fastener is provided below the outer end of the mounting rod, and the L-shaped fastener is buckled on the corner of the support frame, and bolts are provided on the L-shaped fastener, and the L-shaped fastener is fixed to the support frame by the bolts.

[0010] A further improvement is that the tail rope retaining beam is integrally formed with the support frame, and the spacing between the laser detection components on both sides of the tail rope is smaller than the spacing between the two groups of tail rope retaining beams.

[0011] A further improvement is that: a connecting rod is provided at the outer end of the support frame, and at least two groups of connecting rods are provided, and bolt holes are provided on the connecting rods.

[0012] The beneficial effects of the utility model are:

Laser is emitted between the laser generator and the laser receiver, and the signal of the laser receiver is connected to the sound and light alarm. During normal operation, the laser receiver receives the laser. When the tail rope has an abnormal running track beyond the reasonable running range, the tail rope blocks the laser, causing the laser receiver to be unable to receive the laser. At this time, the sound and light alarm sounds an alarm, which is convenient for real-time monitoring and prompts the driver to take corresponding measures to deal with it, so as to avoid the occurrence and expansion of accidents.

[0014] 2. The sound and light alarm of the utility model is connected to a timer, and can be set to sound an alarm when the laser receiver does not receive the laser for more than N seconds, so as to avoid malfunction caused by coal gangue falling in the shaft and instantaneously blocking the laser.
