Problems solved by technology
At present, the rope changing devices used by various mines are mainly processed by themselves. Due to the lack of formal design and strength calculation, there is a problem that the strength of the rope changing devices is not enough, which is a hidden danger to mine safety production.
At the same time, because the main hoist is out of sync with the stabilizing car, there are problems such as rope torsion, twisted bend, new wire rope and old wire rope, new wire rope and new wire rope twisted together, etc., which directly affect the quality of rope replacement, and even make the new rope Damaged, injured, endangering mine safety

Embodiment Construction
[0018] Take the five-rope friction hoist as an example.
[0019] Put the spring 23, the spring seat 24, and the wedge block 26 into the sleeve 22, connect the sleeve 22 with the gland 21 with bolts, and install the needle valve type oil cup 27 on the sleeve 22 to form the anti-running rope Institution 3. Five sets of anti-running rope mechanisms are installed on the mounting frame 28, the hydraulic cylinder 30 is connected with a channel steel 31 by the pin 29, and the U-shaped card 32 fixes the hydraulic cylinder 30 on the mounting frame 28. The channel steel 31 is close to the wedge block 26, and when the piston rod stretches out, the channel steel 31 is driven to move, and the wedge block 26 also moves thereupon, compressing the spring 23. When the hydraulic cylinder 30 moved to the maximum stroke, the new steel wire rope 2 could be passed through five sets of anti-running rope mechanisms respectively. Channel steel 31 adopts 8# channel steel.

Abstract
A quick replacement of multi-cable friction elevator achieves reducing of replacement time and labor intensity, and fsafety. Its apparatus consists of a stepped replacing mechansm, a cable-off preventing unit, and an automatic monitor. The stepped replacing mechansm comprises a stepping cylinder, a clamp, and a basement. The cable-off preventing unit comprises a sleeve, a cable going-through unit, a press cap, a wedge, a spring and a spring base, a hydraulic cylinder, an installing rack, pins, U-shaped clips, needle oil cups, and H-shape steel. The automatic monitor comprises a pressure monitoring alarm which includes an A / D converter, a pressure sensor, PLC, relays, and pressure modules, and a cable-off monitoring alarm which includes a tachogenerator, solenoid valves, an A / D converter, PLC and relays.
Description
technical field [0001] The invention relates to a device for quickly replacing the head rope and the tail rope of a floor type multi-rope friction hoist. Background technique [0002] The maintenance work of the multi-rope friction hoist is more complicated than that of the winding hoist, because the length of each wire rope of the multi-rope friction hoist must be kept equal, so that the workload of replacing, inspecting, and adjusting the wire rope increases. Especially the rope change work. According to Article 379 of my country's "Coal Mine Safety Regulations", the service life of the friction hoist steel wire rope (ie the first rope) shall not exceed two years, and the service life of the balance steel wire rope (ie the tail rope) shall not exceed four years. Therefore, for the main and auxiliary For mines where the wells are all friction hoists, the head rope needs to be replaced once a year on average, and the tail rope needs to be replaced once every two years. At p...
