During work, when the tension of the steel wire rope is lower than a lower limit value set by an industrial personal computer, a tensioning and fixing rope clamping device is pushed upwards to tension the steel wire rope, if the tension of the steel wire rope can not reach an upper limit value set by the industrial personal computer through rising once, the tensioning and fixing rope clamping device is pulled back from above, and the steel wire rope is tensioned by a regulating and guiding rope clamping device and an anti-drop rope clamping device. The flexible guide rail is restrained by longitudinal guiding and horizontal deflection, a guide rail system has a simple structure and a reliable performance, is easy to process, can be simply installed and maintained, and can monitor the tension of the guide rail in real time simultaneously, the safety, the reliability and comfortableness for taking a lift car are improved through the automatic regulation carried out according to the monitored tension, and the automatic tension regulating device for the flexible guide rail of the mine elevator provided by the utility model is particularly suitable for a mine elevator guide rail system which can not be satisfied by a rigid guide rail in underground mine.
Description
Technical field
The utility model relates to a kind of mining elevator flexible guide rail tensile force self-checking device, is particularly useful for the cage guide system that down-hole, mine rigid guideway can't satisfy.
Background technology
At present, mainly adopting rigid guideway aspect the elevator guidance system, because there is error in rigid guideway in design, manufacturing and installation process, bear immense pressure owing to the pitshaft wall again simultaneously, shaft deformation, its guide rail lateral inclination, flexural deformation, radius off-set joint and local projection take place often, thereby cause car violent vibration in promoting operational process; When serious, the elevator sliding guide shoe or the rolling track adjusting wheel that depend on the low gap guide rail are stuck, and cause lift car to be stuck in the pit shaft, bring huge hidden danger for the safe operation of mining elevator, and the people that takes advantage of in the car constitutes life safety hazard.
In existing vertical shaft for mine, the flexible guide rail of existing at present flexible cage guide, mainly be based on the shaft bottom heavy-hammer tension flexible cage guide system, the tension of hydraulic pressure screw rod the flexible cage guide system and based on the Hydranlic tensioner of quick card rope device.Wherein, advantage based on the flexible cage guide system of shaft bottom heavy-hammer tension is that tightening force is stable, but goods etc. is heavy more in the lifting container, and the quality of tension weight will be big more, shared space is also big more, therefore need to dig darker lum, if in the water nest because being sprinkled into of foreign material such as coal cinder, causing lum is that the tightening force of weight reduces by raising, cause the horizontal beat of car serious, inefficiency when adjusting tensile force simultaneously, workman's intensity is big, and the difficult adjustment of the accurate weight of weight; Though the flexible cage guide system of hydraulic pressure screw rod tension has overcome many deficiencies of heavy-hammer tension, but wedge system processing difficulties, voussoir are not easy to enter the bottom of anchor fitting, skid thereby cause between steel rope and the voussoir, cause guide rope to crash into from the top; Though and overcome the drawback of weight hammer type and screw hydraulic pressure tension system based on the Hydranlic tensioner of quick card rope device, but when steel rope causes Permanent extension that the steel rope tensile force is reduced owing to lasting tension force effect, can't realize the tensioning of steel rope automatically, must the workman unclamp steel wire clamping plate, and then the continuation tensioning, if the stroke of oil cylinder is not enough, tensile force out of reach then, need card rope back tensioning again, cause the elevator system low efficiency.
Can find that according to above analysis present mining elevator rigid guideway can't satisfy normal lifting, still not have a mining elevator wire rope system; Big and weight is difficult for regulating based on big, the shared space of the tension weight quality of the flexible cage guide system of shaft bottom heavy-hammer tension; The wedge system processing difficulties of the flexible cage guide system of hydraulic pressure screw rod tension causes easily between steel rope and the voussoir and skids; Can't automatically regulating based on the tensile force of the Hydranlic tensioner of quick card rope device, and problem such as efficient is low.
