Specific embodiment

Utility model is described in further detail with reference to the accompanying drawing:

As shown in figures 1 to 6, the utility model includes cylinder base 1, barrel 2, sealing ring 3, cover 4, and wherein barrel is fixed on cylinder It in seat, is tightly connected between barrel and cover by sealing ring, hinged claw 19 on affiliated cover lateral surface, claw passes through connecting rod Mechanism connects driving mechanism, and the driving mechanism includes cam rotary body 8, portable pillar 9, rotation fluted disc 10, guide post 11, fixes Teeth, portable pillar upper surface setting teeth are arranged on the rotation fluted disc lower end surface in seat 6, disc spring 5 and lower lock fluted disc 7, and cam revolves It turns lower end surface and teeth is set, teeth are arranged in lower lock fluted disc upper surface, and the guide post upper end is fixed on the center of rotation fluted disc The centre bore activity grafting of Kong Zhong, guide post lower end and portable pillar, portable pillar are installed in cam rotary body by flat key 12 In heart hole, the effect of flat key is can be with moving cam rotary body synchronous rotary, in addition, in cam rotary body when portable pillar rotation The keyway in heart hole is longer than flat key, and portable pillar can be slided in leading for flat key downward along axis direction, portable pillar lower end and lower lock Fluted disc center is contacted without the end face part of teeth, and the rotation of cam rotary body is fixed in the centre bore of fixing seat, can be relatively fixed Seat rotation, but cannot move up and down, fixing seat is fixed on cover upper surface, and center column is arranged in cover upper surface center, Gu The centre bore of reservation and center column are coaxial, and disc spring and lower lock fluted disc are successively set on center column, and disc spring supports lower lock Fluted disc, lower lock fluted disc is opposite can be moved up and down with center column, but is not able to rotate, and when work, portable pillar is inserted into guide post lower end Centre bore in and push, for portable pillar along axis slide downward, lower pressure lock fluted disc and disc spring make cam rotary body and lower lock The engagement of fluted disc disengages, and rotation fluted disc is engaged with portable pillar, the rotation of rotary teeth dish driving portable pillar, and then drives cam rotary body Rotation, cam rotary body drive claw clamping or release using cam structure drive link mechanism.When portable pillar is upward along axis When sliding, pressure disappears under disc spring, resiles, and lower lock fluted disc lifts up again, makes the disk tooth of lower lock fluted disc and rotary body Again it engages, realizes self-locking.

The link mechanism includes pin 13, idler wheel 14, driving lever 15, connecting rod 16, big spring 17 and guide pad 18, described to lead It is fixed on cover to block, driving lever activity is inserted into guide pad centre bore, and driving lever can move back and forth along guide pad centre bore, driving lever Idler wheel is connected by pin shaft, idler wheel outer round surface rests on the helix surface on cam rotary body flange face, when cam revolves When swivel rotation, the spiral yarn shaped face on flange face will push driving lever and slide along guide pad centre bore, stroke 8mm, driving lever The other end connects connecting rod one end by pin shaft, and the connecting rod other end connects claw, and big spring is sleeved on driving lever, and is located at guide pad In centre bore, guide pad centre bore is stepped hole, and big spring compresses limit by the ring flange on guide pad and driving lever ontology. The effect of big spring is to remain idler wheel outer round surface to fit closely with spiral yarn shaped face.It, can simultaneously when driving lever sliding Drive connecting rod and claw movement, when driving lever to cover center slide 8mm when, claw be in be flared out state, at this time just with Along disengaging on cylinder base, when driving lever reverse slide returns in situ, claw is in a vertical state, edge on cylinder base is blocked, at this point, idler wheel Spiral yarn shaped face position locating for outer round surface is exactly helix from lock-bit, this function is determined by the style characteristic of helix It is fixed.

The link mechanism and claw are arranged three sets, and claw is L shape, are articulated on the outside of cover in the middle part of claw by pin shaft On the lug in face, three claws are uniformly arranged along cover lateral surface, and three sets of link mechanisms are corresponding with three jaw positions uniformly to be set It sets.

As shown in fig. 7, cover is rotated in the course of work in order to prevent, claw is caused to wear, the clawed end portions are set There are rotation-preventing mechanism 20, including cylinder base, fixed block 21, bolt 22, split pin 23 and little spring 24, wherein fixed block is fixed on card Stepped hole is arranged on the fixed block for pawl side, and the latch body head is equipped with ring flange, and little spring is set on bolt simultaneously The stepped hole that bolt tail portion passes through fixed block is exposed, little spring is made to be limited in stepped hole by ring flange and fixed block compression In, insertion opening pin, is movably connected on bolt in the stepped hole of fixed block on bolt tail portion, and the cylinder base setting is outer to be rolled up Edge is uniformly arranged rectangular channel along outer circumference direction thereon, when claw closes, is prevented in bolt head insertion rectangular channel Turn.

Working principle explanation:

As shown in Figure 1, claw is in gripping orientation, equipment high speed rotation, revolving speed 300rpm, at this point, three claws can be held By outside centrifugal force, but due to the effect of double self locking mechanism, it can be opened to avoid claw, the water in roller is caused to leak. Specifically, it is that spiral yarn shaped face is placed exactly on claw clamping position from lock-bit that first self-locking for double self locking mechanism；Second The self-locking disk tooth engagement for lower lock fluted disc and cam rotary body in road prevents cam rotary body from rotating；Though this two it is self-locking which Since damage parts cause to fail, another road can also continue to play a role in road.

When work, rotation fluted disc is fixed on the rotary cylinder of equipment lifting body, and with cylinder synchronous rotary, guide post is fixed In rotary teeth center hole, after work, rotation fluted disc declines with lifting body, guide post first insertion activity during decline Progress is regulatory in column centre bore, continues decline and engages with the teeth of portable pillar upper end, and then push portable pillar, passes through lower lock fluted disc Disc spring is compressed, disengages lower lock fluted disc and rotation body disc tooth engagement, while lower pressure compresses sealing ring, under equipment lifting body After dropping to position, claw is separated with the lower surface on edge on cylinder base, and rotary cylinder rotates clockwise, by the engagement force band for rotating fluted disc The rotation of moving cam rotary body, makes three claws while opening, the grasping mechanism in equipment integrally catches cover, passes through lifting body Raising has carried cover.

After cover is opened, can by cylinder abrading block and water and processing part take out, the abrading block and water that more renew and Part, lifting body decline, cover is put down, rotary cylinder rotates counterclockwise, and three claws close simultaneously, the gripper in equipment Structure unclamps cover, and lifting body rises, and pressure disappears under disc spring, resiles, and lower lock fluted disc lifts up again, make lower lock fluted disc with The disk tooth of cam rotary body engages again.The pressure of sealing ring disappears, and resiles, and makes on three claws and cylinder base under edge Surface contacts again and tensioner.

Although three claws contact again with the lower surface on edge on cylinder base and tensioner, cover is possible in high speed rotation Relative rotation can occur between cylinder base, so devising rotation-preventing mechanism, relative rotation is avoided to cause the abrasion of claw.When three When claw closes, it is possible to which bolt head does not enter in rectangular channel, but has been withstood on outside rectangular channel, and little spring is to be pressed at this time The state of contracting, when equipment high speed rotation, relative rotation occurs for cover and cylinder base, and little spring can be easy to the jacking of bolt head In rectangular channel, anti-rotating function is realized.
