Abstract
A torque regulating winching reel belongs to an output reel device f the winching draw machinery, characterized in that a shaft shoulder of the conventional winching output shaft is provided with a friction retaining ring which has a key slot, which is sequentially assembled together with a winching reel which having a small-taper taper hole, a small-taper taper sleeve having a key slot, and a pressure adjustment device to form a torque regulating winching reel, wherein the utility model utilizes the friction principle to approximately linearly adjust the pressure between the reel, and the friction retaining ring and the taper sleeve through fastening the pressure adjustment device on the winching output shaft end, in order to change the friction resistance of the reel and realize the torque regulating function of the winching reel; and the friction retaining ring is fixed with the reel through a fixing bolt, and the torque regulating winching reel changes into the conventional reel when pressing the adjustment device. The device can be assembled on the output shaft of the winching, finish the drawing and lifting of the load, realize that two or more than two winching groups can synchronously draw the non-potential energy load and have the draw protection function through adjusting the torque, and at the same time keeps all capabilities of the traditional winching reel.
Description
Technical field
The utility model belongs to the output class roll device of strand mill trailer-type machine; can be installed on traction, the lifting of finishing load on the output shaft that twists mill; by the torque of adjusting; can realize that 2 and above strand mill group to non-position (gesture) portative traction synchronously and had the traction protection function, have kept all properties characteristic of traditional strand mill simultaneously.
Background technology
At present, known strand mill can be divided into artificial strand mill, motor-driven strand mill and electronic strand according to type of drive and grind three classes, except that artificial strand mill, mainly is made up of pedestal, engine installation, transmission system and feed roll (being commonly called as core grinding) four parts.Accessory appliancess such as rope are closed in the strand grinding-in, can realize the lifting or the traction of load, be applicable to the field work and the truck conspicuity marking unapproachable camp site with a varied topography that do not have power supply, have the advantages that not to be subjected to the hauling rope limitation of length, be used for the traction and the lifting of constructions such as transmission line of electricity, cable work and pipeline laying more usually.Common strand mill can only use by unit, and reel and output shaft are rigidly connected, and can't realize traction protection and online synchro control excessively to load, has limited its field of application.
The utility model content
Goal of the invention of the present utility model is the defective at tradition strand mill; a kind of square strand mill reel of turning is provided; on the basis that keeps strand mill original function; increase is to the traction protection and the online synchronization control function excessively of load; the birth defect that exists when mainly overcoming it and being used for cable pulling and laying is widened the field of application of strand mill.
The technical scheme in the invention for solving the technical problem is: the friction back-up ring that a band keyway is set at routine strand mill output shaft shaft shoulder place, together assemble with the strand mill reel that has conelet degree taper hole, the conelet degree tapered sleeve and the pressure regulation device that have a keyway successively, form and turn square strand mill reel, utilize tribology principle, pressure regulation device by fastening strand mill output axle head, the pressure of approximately linear ground adjustment reel and back-up ring, tapered sleeve, change the friction drag of reel with this, that realizes strand mill reel turns the square function.
Uniform 4～6 screws of reel small bore end, when strand mill was used for potential energy load etc. and does not need to adjust the operating mode of torque, it was fastening to utilize socket bolt that reel is connected with the friction back-up ring, while compaction pressure setting device, turn square strand mill reel and become one, change conventional strand mill reel into.
The utility model has the advantages that: technical scheme is simple and practical, has expanded the functions of use of conventional strand mill effectively, can realize traction protection and online synchronization control function excessively to load, has significantly improved the cost performance of equipment; Scheme implementation or existing conventional strand mill are transformed economical, easy, practical; Simple to operate, easy to use, reliable, be easy to promote.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model be used to encorbelment sectional structure chart of output shaft strand mill.
Fig. 2 is the sectional structure chart that the utility model is used for fixing output shaft strand mill.
Turning each component names of square reel among Fig. 1,2 is: turn the square reel, 2. tapered sleeve, 3. flat key, 4. pressing plate, 5. adjustment nut (packing ring), 6. adjustable bolt, 7. friction back-up ring, 8. dowel bolt, the 9. strand mill output shaft of encorbelmenting, the 10. fixing output shaft of strand mill 1..
The specific embodiment
In Fig. 1, earlier flat key (3) is put into the keyway that strand is ground output shaft (9) of encorbelmenting, the back-up ring (7) that will rub is installed in the shaft shoulder place that strand is ground the output shaft (9) of encorbelmenting, pack into successively then and turn square reel (1), tapered sleeve (2), again adjustable bolt (6) is screwed in to twist in the screw that grinds output shaft (9) the spindle nose end of encorbelmenting and tighten, pack on it pressing plate (4), packing ring and adjustment nut (5) are turned the assembling of square strand mill reel and are finished.
When adjusting the torque of strand mill reel, to twist the mill anchoring earlier, the tail rope of monocycle rope sling is penetrated in the tail rope knock hole of reel, rope sling utilizes shackle to connect draw-bar donamometer and chain block after turning last winding five circles of square reel (1), the mobile terminal anchoring of cucurbit, in fastening adjustment nut (5) gradually, the tension chain block to turn square reel (1) overcome under the effect of pulling force with tapered sleeve (2), rub between back-up ring (7) the static friction resistance and produce relative slippage, when pulling force reaches the requirement setting valve, tighten double nuts, the red paint sealing, the torque adjustment finishes.
During use, hand over adjusting during pulling force of mill reel more than or equal to turning square, turn square reel (1) and stop operating automatically, realized the traction protection function when load resistance; When load resistance during less than the dynamic friction resistance turned between square reel (1) and tapered sleeve (2), friction back-up ring (7), turn square reel (1) and recover automatically to rotate, go round and begin again, realize the synchro control of strand mill group.
When the strand mill is used for the load of lifting potential energy or does not need to adjust torque, can and turn friction back-up ring (7) and together install after square reel (1) uses dowel bolt (8) fastening, the back is installed tightens adjustment nut (5) according to the permission Tightening moment of adjustable bolt (6), compress tapered sleeve (2), at this moment, turn square strand mill reel and become conventional strand mill reel.
Turn square strand mill reel and can be used for existing conventional repacking of twisting mill.
Constructional drawing when being provided with the movable axis bearing embodiment illustrated in fig. 2 for strand mill output shaft axle head, the same Fig. 1 of principle.
