And effect is clearer, clear, and the utility model is further described as follows in conjunction with drawings and embodiments.It should manage
Solution, specific embodiment described herein only to explain the utility model, are not used to limit the utility model.
Please refer to Fig. 1-4, a kind of drum clamp system of frame winch provided by the utility model, including it is multiple along frame winch
The circumferential evenly arranged clamping component A of main cage 3 '；Each clamping component A includes be respectively used to 90 both ends of wire coil clamping first
Collet 1 and the second collet 2；First collet is rotatably arranged on a connection frame 3.1 ' of main cage；The first collet of face it is another
A guide cylinder 3, the axis collinear of the axis of guide cylinder and the first collet are provided on one connection frame 3.1 ', the second collet is slided
Dynamic to be plugged in guide cylinder, guide cylinder is provided with a worm type of reduction gearing 4 and driving motor far from one end of the first collet
5, driving motor is connect with the worm screw of the worm type of reduction gearing, and the output shaft of the worm type of reduction gearing is screw rod 4.1, described
Second collet is axially disposed corresponding internal thread hole 2.1, and screw rod 4.1 is connect with internal thread hole 2.1, and energy when screw rod rotation
Enough drive the second collet mobile.
When work, the first collet and the second collet are respectively used to wire coil clamping both ends, wherein the second collet is by driving motor
It drives worm type of reduction gearing to realize by the transmission effect of screw rod and internal thread hole to move back and forth, to realize the folder to drum
Tight and release, since worm type of reduction gearing has the function of reverse self-locking, that is, can only be rotated by worm drive worm gear, Wu Fayou
The rotation of worm-gear driven worm screw, therefore, the extruding force (from drum) that when the second collet wire coil clamping is subject to can not make worm gear
Rotation, so that the second collet can not be made to retreat；Compared with cylinder in the prior art adds the drum clamp system of retaining mechanism, knot
Structure is simpler, and reliability is higher.It is not to folder although only being depicted in Fig. 1 and having the case where there are four clamping component A
The restriction of tight component count.
Specifically, seeing Fig. 3, second collet 2 includes the slide bar 2.2 being slideably positioned in guide cylinder 3, and rotation is set
It sets on the pinnacle 2.3 of slide bar outboard end (i.e. towards one end of the first collet)；Slide bar and guide cylinder are keyed, the internal screw thread
Hole 2.1 is provided on slide bar 2.2.Herein, since slide bar and guide cylinder are keyed, slide bar can be only axially moveable, can not
It rotates, so that ensure that can reliably drive the second collet mobile when screw rod 4.1 rotates.
Further, the outboard end of the slide bar 2.2 offers bearing mounting hole, is provided with two in the bearing mounting hole
A angular contact bearing 2.4, two angular contact bearings are oppositely arranged, and the pinnacle 2.3 has a shaft 2.3a, the shaft grafting
In two angular contact bearings 2.4.Since angular contact axis is able to bear biggish unidirectional axial force, two angular contact axis
It holds oppositely arranged, it is ensured that pinnacle can not be relatively moved along axial, to will not fall off.
Herein, the root of shaft 2.3a is provided with the shaft shoulder, and the inner ring of the shaft shoulder and an angular contact bearing 2.4 offsets, and two
A sleeve is provided between the inner ring of a angular contact bearing 2.4, which offsets with an even inner ring respectively, bearing installation
Hole bottom setting is additionally provided with a sleeve, the sleeve both ends respectively with the bottom of bearing mounting hole and another angular contact axis
2.4 outer ring is held to offset.The structure can further ensure that toward 2.2 direction of slide bar Relative sliding will not occur for pinnacle 2.3, avoid
Pinnacle 2.3 offsets with 2.2 end face of slide bar and influences it and be freely rotated.
Preferably, each clamping component A further includes the rotary coding of one with the output axis connection of worm type of reduction gearing 4
Device 6.By rotary encoder can real-time measurement screw rod 4.1 rotational angle, since the dimensional parameters of screw rod are fixed, the second collet
Moving distance it is directly proportional to the rotational angle of screw rod 4.1, therefore the second folder can be detected by the rotational angle that measures indirectly
The moving distance of head is shut down in due course to control driving motor 5, is avoided the second collet excessive compression drum 90 and is caused drum broken
It is bad.
In the present embodiment, the driving motor 5 is connected by fixing seat 7 with corresponding connection frame 3.1 '.Due to worm gear snail
Bar retarder 4 is connected with guide cylinder 3, and driving motor 5 can be realized and being connected with worm type of reduction gearing and is fixedly mounted,
But biggish centrifugal force is generated due to that can rotate with main cage 3 ' when guide cylinder is cantilever design and works, it is easy to cause spiral shell
Silk loosens and malformation；Setting fixing seat 7 can avoid such case appearance herein.
Specifically, seeing Fig. 4, the fixing seat 7 is including connection ring 7.1, the fixed plate 7.2 being spirally connected with connection frame 3.1 ', with
And it is connected to connecting plate 7.3 and gusset 7.4 between connection ring and fixed plate；The driving motor 5 is fixed on connection ring 7.1
In.The weight of the fixing seat is smaller and structural strength is larger.
Further, the connection ring 7.1 has an opening, and opening two sides are provided with protrusive board 7.1a, two protrusive boards it
Between be connected with clamping screw 7.1b.By tightening clamping screw 7.1b, connection ring can assemble and disassemble driving motor banding simply, make
With conveniently.
Specifically, first collet 1 includes round plate 1.1, the ogival 1.2, Yi Jizhuan at round plate center is set
Axle portion 1.3；Shaft 1.3 is rotatablely connected with corresponding connection frame 3.1 '；Clamping component A turns to replacement position with main cage 3 '
When, round plate support is in 90 bottom of drum.When carrying out the replacement of drum, usually first the drum needed replacing is turned to fixed
Direction, so that worker replaces, which is the replacement position, by taking Fig. 1 as an example, for the right positions in figure, at this point,
If the second collet is in propradation, drum only leans on the first collet to support, and round plate is arranged herein can increase supporting surface, keeps away
Exempt from drum to topple over.
Further, the shaft 1.3 is plugged in two oppositely arranged angular contact bearings 8, two angular contacts
Bearing 8 is arranged in a bearing block 9, and the bearing block and corresponding connection frame 3.1 ' are spirally connected fixation.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement all should belong to the protection of the utility model
Range.
