Abstract
The utility model relates to a traction device for a steel wire detecting machine, which comprises a rack and a wire pulling traction device and a wire drawing traction device which can be arranged at both sides of the middle of the rack respectively in rotation. A differential speed transmission mechanism is arranged between the transmission shafts of the wire pulling traction device and the wire drawing traction device, which comprises a magnetic particle clutch driven by a power machine, a drive end of the magnetic particle clutch is in transmission connection with the transmission shaft of the wire drawing traction device via a first speed reducing transmission device and a driven end of the magnetic particle clutch is in transmission connection with the transmission shaft of the wire pulling traction device via a second speed reducing transmission device. The transmission rate of the first speed reducing transmission device is less than the transmission rate of the second speed reducing transmission device. The first and second speed reducing transmission devices allow the wire pulling traction device and the wire drawing traction device to generate a speed difference to tension the steel wire; the magnetic particle clutch is used to realize power feedback, thereby a low power machine can be selected to drive the traction devices so as to reduce the structural dimension and the material cost of the power machine.
Description
Technical field
The utility model relates to the draw-gear on a kind of the wire rope machines that is used to be detected as spooling tension force, particularly wire rope machines.
Background technology
Wire rope uses very extensive in industries such as building, coal, mine and sea transport, except that being used for towing, hoist cable, also be used for various forms of transmissions and carry the people in lifting gear carrying, carry thing etc., because wire rope is directly connected to the safety of production safety and the person and property, and used wire rope ubiquity defectives such as fracture of wire, wearing and tearing, corrosion and fatigue damage in various degree, so regulation all will be carried out regular check and maintenance to the wire rope in the term of life.
Chinese patent ZL03108173.8 discloses a kind of steel rope inspection equipment, this device is provided with retractable line rope traction wheel in the frame both sides, the traction wheel of both sides adopts a through-drive, this drive mechanism need be driven by very large output torque, make that the motor that drives traction wheel is bulky, heavy, mechanical efficiency is low, energy consumption is big, and this structure can not realize the wire rope tensioning, detects steel wire rope tension and also special strainer need be set.
The utility model content
The purpose of this utility model provides the wire rope machines draw-gear of a kind of efficient energy-saving and the wire rope of tensioning simultaneously.
For achieving the above object, the utility model adopts following technical scheme: wire rope machines draw-gear, comprise frame and rotatable respectively unwrapping wire draw-gear and the take-up draw-gear that is installed on the central rack both sides, receive, between the transmission shaft of unwrapping wire draw-gear differential gear is installed, this differential gear comprises the powder clutch that is driven by engine, the drive end of powder clutch is in transmission connection by the transmission shaft of first speed reduction gearing and take-up draw-gear, the driven end of powder clutch is in transmission connection by the transmission shaft of second speed reduction gearing and unwrapping wire draw-gear, and the ratio of gear of first speed reduction gearing is less than the ratio of gear of second speed reduction gearing.
Described first speed reduction gearing and second speed reduction gearing are cogwheel gearing.
Described retractable line draw-gear includes two traction wheels side by side, that be rotatably installed in the frame side, end near frame on two traction wheels is equipped with gear wheel, be provided with simultaneously the pinion wheel with two gear wheels engagements between two gear wheels, the pinion shaft of retractable line draw-gear is the transmission shaft of retractable line draw-gear.
The traction wheel diameter of retractable line draw-gear is identical.
The utility model is installed differential gear between retractable line draw-gear, make the rotating speed of the rotating speed of take-up draw-gear greater than the unwrapping wire draw-gear, thereby make take-up length in the unit interval greater than unwrapping wire length, make the wire rope tensioning between the retractable line draw-gear, rack-mounted like this device for measuring force can be tested the wire rope of tensioning.First, second speed reduction gearing not only makes retractable line draw-gear produce speed discrepancy, and increased moment of torsion, thereby can select the lower propulsion system of power to drive retractable line draw-gear, also reduced the physical dimension and the material cost of drive unit simultaneously; The powder clutch volume is little, from heavy and light, easy for installation, tension force is easy to regulating and controlling, especially in the course of the work, the tension force of wire rope facilitates the rotating speed of powder clutch driven shaft greater than speed drive shaft, has realized Feedback of Power, improve mechanical efficiency, further reduced the power of selecting for use of propulsion system.In addition, because the existence of speed discrepancy can make the traction wheel diameter of retractable line draw-gear identical, retractable line traction wheel can be general like this, and processing and assembling are all very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, wire rope machines draw-gear comprises frame 1, rotating unwrapping wire draw-gear 3 and take-up draw-gear 4 are installed in the central rack both sides, wherein, unwrapping wire draw-gear 3 comprises two side by side, the rotatable traction wheels 31 that are installed in the frame side, end near frame 1 on two traction wheels 31 is equipped with gear wheel 33, is provided with simultaneously the pinion wheel 32 with 33 engagements of two gear wheels between two gear wheels 33; Take-up draw-gear 4 comprises on 41, two traction wheels 41 of two traction wheels side by side, that be rotatably installed in the frame side that a side of frame 1 is equipped with gear wheel 43 relatively, is provided with simultaneously the pinion wheel 42 with 43 engagements of two gear wheels between two gear wheels 43.The gear shaft of pinion wheel 32,42 be put, the transmission shaft of take-up draw-gear, traction wheel 31 is identical with the diameter of traction wheel 41.
During work, starter motor 21, and make powder clutch 22 energising work, motor 21 drives take-up draw-gear 4 and rotates, tensioning under the effect of the coiling frictional resistance of wire rope between itself and retractable line draw-gear traction wheel, the wire rope after the tensioning drive unwrapping wire draw-gear 3 again and rotate, and make the rotating speed of powder clutch driven shaft greater than the powder clutch speed drive shaft by the second gear reduction gearing 25 (what realize this moment is the speedup transmission), realize Feedback of Power, improve mechanical efficiency.
