Description
The present invention relates to a kind of hauling Machine with rope with CD-ROM drive motor, power-transfer clutch, retarder and steel cable driving disk.
People know the small-sized hoisting device of electronic deceleration substantially, and this hoisting device is particularly useful for the vertical-lift of load, so its application is restricted.For electric block or have rope drum and the capstan winch and the bont of necessary drg also are like this.For this reason, the hoisting device of known electronic deceleration often needs very big installing space, and owing to its heavier weight makes operating difficulties, in addition, is impossible as the combiner of hoisting device, steel cable actuating device and drum driving apparatus.Here, the present invention will eliminate above-mentioned defective.
Task of the present invention is, the light hauling Machine with rope of the above-mentioned type is provided, this hauling Machine with rope has structure and less weight and big tractive force, high steel cable kinematic velocity and the characteristics of being convenient to operate closely, it can be used as hoisting device, can be used as steel cable actuating device or cableway actuating device and drum driving apparatus equally.
The present invention has so solved this task, being its clutch configuration of above-mentioned hauling Machine with rope is disk clutch or plate disc brake that can be hand, reducer structure is an epicyclic reduction gear, disk clutch is arranged on the transmission shaft of driven epicyclic reduction gear, between epicyclic reduction gear and disk clutch, be provided with a Drive pinion that is used to drive the steel cable driving disk at disk clutch driving device side bonded assembly, the steel cable driving disk is installed with conical bore, this driving disk has one and Drive pinion ingear ring gear, according to a preferential version of the present invention, the inter-engagement of disk clutch by releasable pressure element is by operating as the hand crank of adjustable decline drg.This measure of the present invention at first has this result, and promptly load can realize descending with hauling Machine with rope of the present invention based on its deadweight and adjustable braking force.Descend accurately or promote for load, in fact realized common brake system that can meticulous adjusting, so that can be as accurate as millimeter and insert a pin, bolt, machine part or its analogue with disk clutch.If CD-ROM drive motor does not have brake action (gasoline, pressurized air), the planetary gear carrier that retaining pawl is installed so is as the counter-rotating locking.The locking of reversing when promoting is inoperative to rotatablely moving, as long as planetary output shaft antiport, retaining pawl slips into inner gear immediately and pins drive system, at this moment can discharge drive system and decline load by disk clutch.Planetary gear train makes king-sized transmitting ratio become possibility, and this is particularly suitable for CD-ROM drive motor among the present invention through the cone belt speed reduction gearing with drive the situation of planetary gear train in case of necessity by the inter-engagement of intermediate belt gearing.Pay the utmost attention to as CD-ROM drive motor be combustion engine, but also can consider with air motor or electro-motor.Nearly 1: 600 of total reduction ratio.With regard to the weight aspect, the light planetary gear train and the combination of disk clutch guarantee minimum friction drag and high efficient, so that can therefore be particularly suitable for the operation that cable railroad assembler, steel structure assembler and snowslide intercept the worker with big tractive force, high rope moving velocity and light total from focusing on aloft work by hauling Machine with rope of the present invention.The rope driving disk of installing with conical bore makes possibility that be mounted for of annular weaving steel cable, thereby makes and not only can be used as bont according to hauling Machine with rope of the present invention, and can be used as rope driving or cable railroad actuating device.In fact, the annular weaving steel cable can be laid on each position of steel cable driving disk, and needn't the sharpening steel cable, wear the end of steel cable or take the cable traction machine apart.In addition, this layout of planetary gear train, disk clutch and steel cable driving disk reaches an exceptionally close structure, and this structure has the hollow shaft of steel cable driving disk Drive pinion and optimization by being installed on the planetary gear train axle drive shaft one with disk clutch actuating device side bonded assembly.In addition, can for the rope driving disk be provided with a rope track adjusting wheel and one rotatable install stretch into rope pressure roller in the rope driving disk grooving, steel cable (or rope) tractive force of this pressure roller and load reversion section is worked pro rata.Whereby, propulsive effort or pulling force are delivered on the relevant steel cable safely.In addition, the present invention considers that in advance the steel cable driving disk has jack that inserts brake stopper and the grafting power-transfer clutch that is used to drive any machine or equipment, like this, driven machine or equipment can discharge pinning under the same power under the torque that is being in drawback movement under arbitrary torque in quiescence or by disk clutch or is reducing.In this way, a spool actuating device or drum driving apparatus have been formed simultaneously according to hauling Machine with rope of the present invention, because relevant reel can drive at the other sprocket wheel of grafting power-transfer clutch through one by a driving chain, certainly, reel has a corresponding ring gear for this reason.Like this, to remove big spool of direct drive or reel be possible by connecting in the middle of the additional chain gear with hauling Machine with rope of the present invention,, has deadweight less than 30Kg according to hauling Machine with rope of the present invention here.Consequently the function of the function of bont and wire drive or cable railroad actuating device and the function of spool actuating device are combined.
Epicyclic train; Plate clutch and steel cable driving-disc are installed in the housing; The steel cable driving-disc case lid that can axially move is installed at clutch housing; ，Ｍぷ⒒０⒚”ＴüＴ⒚ＲＲぷＲτο。
Its result, because hauling Machine with rope is in light weight, it can be used as can take machine, thereby is convenient to operation, but has guaranteed with the big pulling force of high rope speed transmission, same, the accurate decline of load and lifting also are possible.Realize steel cable, rope drum, cable hoist thus and else wanted the comprehensive driving of actuating device.Like this, hauling Machine with rope of the present invention can be applied in for example high steel structure, can be applicable to equally on cable railroad or the mast, equally, this machine also can be used for reinforced concrete building, bridge construction and all lifting and towages, (lifting personnel or weight in rescue cause and forestry, the vehicle that upset is reversed, drag trees away, stone etc.) also can consider to use hauling Machine with rope of the present invention, equally, this hauling Machine with rope also is suitable for avalanche protection operation and dismounting operation, certainly, in the cable tunneling, hauling Machine with rope of the present invention is suitable for drawing lead, cable, pipeline section etc., at last, hauling Machine with rope of the present invention also can be used as mine capstan winch that draws heavy-duty vehicle or the rigging equipment that is used for the dismounting operation.
The present invention is further elaborated by the accompanying drawing of representing an embodiment below.The figure expression:
