Abstract
The utility model provides a PLC (Programmable Logic Controller) frequency conversion speed reducing device for a winch. The PLC frequency conversion speed reducing device comprises a planet carrier and a gear coupling plate arranged at one end of the planet carrier, wherein a plate unloading screw hole is formed in one end of the planet carrier; an axial positioning plate and a cap screwing oil cup are arranged on the gear coupling plate; a high-speed brake wheel controlled by a hydraulic oil cylinder is arranged on the end face of the gear coupling plate; and a mode that the high-speed brake wheel controlled by the hydraulic oil cylinder is arranged on the end part of the gear coupling plate for controlling replaces the traditional mode that a flywheel required for adjusting the speed is arranged at the end part of an inner gear shaft. A mechanical governor reducer as a speed reducing device is changed into a speed reducing device required by frequency conversion of the PLC.
Description
Technical field
The utility model relates to the mining equiment technical field, refers in particular to a kind of PLC frequency conversion speed reduction gearing that is used for winch.
Background technology
Mine hoisting is the mine major equipment; Its power is big, transportation range is long, speed is fast; Keeping under the lifting traction force unmodified situation, needing to pursue shelves and accelerate to maximum speed, existing winch is to adopt the mechanical system of planetary differential to carry out speed governing mostly; Adopt the shortcoming of this class formation to be: the first, will assemble brake wheel, thereby cause the long rigidity of pinion carrier that makes of pinion carrier not enough owing on the pinion carrier; The second, because difficulty is controlled in the not corresponding restriction of tie-plate when causing speed governing; Three, over-the-road expense is high, cost is big and can't use automatically controlled.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, a kind of compact conformation is provided and can satisfies frequency conversion electrical control or the speed reduction gearing of the automatically controlled requirement of PLC.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of PLC frequency conversion speed reduction gearing that is used for winch; It includes pinion carrier and the gear tray joint shaft that is assemblied in pinion carrier one end; Pinion carrier one end is provided with and unloads the plate screw, and the gear tray joint shaft is provided with axial location plate and screw-down type grease cup, and gear tray joint shaft end face also is equipped with the high speed brake wheel through hydraulic ram control.
This programme is after original mechanical speed governing hoist redution gear is carried out a spot of change; Change system into the retarder that is used for the automatically controlled frequently or automatically controlled requirement of PLC of distribution transforming that existing peace mark requires; The pinion carrier of this programme has been saved the part of dress brake wheel; Shorten the length and the weight of pinion carrier, and increased a screw that unloads top board.The gear coupling dish has increased the rotation that the axial location plate that links with casing limits tie-plate on original tie-plate, shortened the length of tie-plate accordingly, has reduced two pairs simultaneously and has been used to support the deep groove ball bearings that tie-plate rotates.Before the internal tooth shaft end has been cancelled, be used for the required fly wheel governor of speed regulation process, change into being equipped with through the high speed brake wheel of hydraulic ram control and control at gear tray joint shaft end face.Speed reduction gearing has been changed over by the mechanical speed governors retarder be used for the needed speed reduction gearing of PLC frequency conversion.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
The specific embodiment
Below in conjunction with institute's drawings attached the utility model is described further; The preferred embodiment of the utility model is: referring to accompanying drawing 1; The said PLC frequency conversion speed reduction gearing that is used for winch of present embodiment includes pinion carrier 1 and the gear tray joint shaft 2 that is assemblied in pinion carrier 1 one ends; Pinion carrier 1 one ends are provided with and unload plate screw 6, and gear tray joint shaft 2 is provided with axial location plate 3 and screw-down type grease cup 4, and gear tray joint shaft 2 end faces also are equipped with the high speed brake wheel 5 through hydraulic ram control.Compare with existing structure: saved the part of dress brake wheel on the pinion carrier 1 of this programme, shortened the length and the weight of pinion carrier 1, increased the rigidity of pinion carrier 1, on pinion carrier 1, increased a screw 6 that unloads top board.The gear coupling dish has increased the rotation that the axial location plate 3 that links with casing limits tie-plate on original tie-plate, shortened the length of tie-plate accordingly, has reduced two pairs simultaneously and has been used to support the deep groove ball bearings that tie-plate rotates.Before the internal tooth shaft end has been cancelled, be used for the required fly wheel governor of speed regulation process, change in the assembling of gear tray joint shaft 2 end faces and controlling through the high speed brake wheel 5 of hydraulic ram control.Speed reduction gearing has been changed over by the mechanical speed governors retarder be used for the needed speed reduction gearing of PLC frequency conversion.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
