It is on April 25th, 2017 that the present patent application, which is application No. is the 201710279300.1, applying date, entitled " a kind of The divisional application of vertical tyre disassembling devices ".

Technical field

The present invention relates to large and medium-sized tyre dismounting technical fields, more particularly, to large and medium-sized vertical tire attaching/detaching apparatus.

Background technique

The motor bus that is travelled on road at present, light truck, engineering truck large and medium-sized tire be by cover tire and wheel mostly Rim tubeless tyre dimerous (i.e. vacuum tire), also having part tire is to have the tire of the inner tube of a tyre or with opening pressure ring Tire.

Traditional mutual disassembly's tire method is unable to satisfy the demand of existing tyre dismounting already, is replaced using mechanical equipment Traditional mutual disassembly's tire has been irresistible trend.And with the expanded demand that auto repair is maintained, to tire The demand of attaching/detaching apparatus also increases year by year.

Maintenance equipment of the tyre disassembling devices as automobile, mainly removes automobile tire and again from wheel rim It installs, repairing, replacement, installation etc. for automobile tire.Current title has tyre removing machine, tyre detacher, and tire is torn open Installation, tire stripping installation, assembling-disassembling machine for tyre, machine for dismounting tyre etc..

Horizontal tire changer and vertical tire changer can be divided into according to the design structure of tyre disassembling devices.

Existing giant tire attaching/detaching apparatus mainly with horizontal tire changer be main frame mode for example Horizontal tire changer disclosed in CN89221149, a kind of cart tire changer disclosed in CN2367494. It includes rack, base and hydraulic power system that CN200420016241, which is disclosed a kind of, and rack and base connect into the sleeping of L shape Formula machine for dismounting heavy tyre.CN201120181220 discloses similar Horizontal hydraulic machine for taking down tyre.But horizontal tire changer Product structure bulky, operating position cannot be directed at tire centerline completely in tyre dismounting operating process, and expense is compared in operation Power, cumbersome time-consuming, and many operational motions needs are accomplished manually, and when operation takes up an area bigger, is needed using user certain big Operation place.

Various drawbacks based on horizontal tire changer are difficult to solve again for the moment, and many researchers begin trying to big The vertical tire changer of type tire is researched and developed, it is desirable to solve the problems, such as above-mentioned urgent need to resolve by vertical tire changer.

In the prior art, the platen of vertical tyre detacher and skid plate are fixedly connected with column, between platen and skid plate Distance be it is fixed, when the wheel of the ultra-large type to different size carries out tearing tire open, the distance between platen and skid plate be will affect To the operation of skid plate.

In order to solve the problems, such as trivial operations caused by above-mentioned distance is fixed, CN201520765413.9 provides one kind and tears tire open Machine platen (pressure roller) structure, including be sheathed on tyre detacher column and can the sliding rack that slides up and down of opposite column, the sliding The slide that frame side is provided with guide shaft and is slidably matched with guide shaft is provided with the support rod forward extended out, institute on the slide Support rod front end is stated equipped with the platen with support rod rotatable engagement.

Although platen can be moved up and down with respect to sliding rack in above-mentioned apparatus while sliding rack drives platen to move up and down The fine tuning for realizing height, but produces another significant drawback, is exactly that the column that needs of this kind of vertical tyre detacher is non- The column of normal height, some actual uses is even more than two meters, and substantially increasing due to column, not only in complete machine shipment When it is very inconvenient, be also required to other big machineries when complete machine dismounting and be used cooperatively, meanwhile, in practical operation When can all be relatively moved due to the position of skid plate and platen, the requirement instead resulted in operator is higher because Operator is difficult to accurately to be positioned at a fixed point and carries out tearing tire and dress tire operation open.

A new technical problem is produced in turn, is how to reduce the height of column, while being capable of providing fixation Operation site, keep operator easy to operate.It is an object of the invention to mention for reduction stem height and simultaneously New technical solution is proposed for the technical issues of fixed operation site.

When dismounting tire, it is often necessary to carry out locking positioning, common wheel rim retaining mechanism or positioning device to wheel rim The problems such as generally existing structure is complicated, and mechanism is huge, inconvenient to use.

Circular rim locking device, which is generally called, makees wheel rim chuck, and tyre detacher chuck is horizontal for fixing wheel rim on tyre detacher Tyre-disassembling machine is to lean against wheel rim side to fix on chuck, but vertical tyre-disassembling machine is just needed wheel rim accumbency in chuck On, when tearing tire open, chuck needs to bear very big tangential force and axial force, needs rapidly to unload lower whorl in time after the completion of tearing tire open Rim, this just has higher requirement to the structure of chuck.

CN201120249050.5 provides a kind of rim locking chuck device, including rotary table, and circumference is set under the rotary table It is equipped with toothed disc, the rotary table side is provided with the positioning pin to cooperate with radial plate rim aperture, rotary table upper side edge Radial equipartition has several radial slots, be respectively arranged on the radial direction slot driven by center reciprocating drive mechanism it is reciprocal Sliding block, the reciprocating block slider lateral border are provided with the locating slot for making wheel rim centering and locking.

But there are three technological deficiencies for the chuck assembly, first is that center reciprocating drive mechanism is very laborious when in use, In fixed wheel rim, need biggish strength turn driving mechanism that positioning pin could be shifted onto the position of positioning；Second is that due to adopting It is groove transmission, the groove in tooth post knob and long slot hole after prolonged use, is easy to form groove and wear, cause The durability of device is not high；Third is that needing to bear biggish tangential force during tearing tire open, chuck assembly is caused to be easy to loosen, It is difficult to ensure the locking stability of single unit system, in actual use, wheel rim is easy to shake on rotary table.

Another object of the present invention is the defect for above-mentioned tyre detacher chuck assembly, proposes a kind of new chuck knot Structure solves above-mentioned chuck assembly, and produces superior technique effect.

The use of tyre detacher skid plate tears that tire efficiency is extremely important open for raising, but to the support construction and fixation of skid plate The research and development of the operating position of skid plate are always the direction that research staff constantly explores.CN201520765410.5 proposes a kind of curved The skid plate of folding, the skid plate upper end are hinged with a connecting rod front end, are provided on the bracket at rod rear end and connecting rod phase Vertical horizontal limit rotary shaft is to withstand rod rear end；When carrying out tearing tire open, by skid plate rotate down insertion tire and wheel rim it Between make rod rear end head on limit rotary shaft to be rotated up to limit skid plate.Articulated shaft one end between the connecting rod and skid plate is outside Extend and be fixedly connected with one end of an extension spring, the other end of extension spring is fixed on the stent side portion, and the limit turns One end of axis extends outwardly and the end of its extension is provided with handwheel, rotates handwheel after tearing tire open and drives limit rotary shaft Rotation is made rod rear end creep upwards under limit rotary shaft drive along limit rotary shaft and climbs over limit rotary shaft, turned with contact limit The limit of axis and connecting rod, skid plate can be rotated up under extension spring effect and pack up.

Although above-mentioned apparatus structure seems simply, but uses security risk there are very big, horizontal limit is used When shaft withstands rod rear end, it is easy to appear the problem of rod rear end skidding can't hold out against after a period of use.The skid plate simultaneously The operating position that skid plate can not also be adjusted can not reach some tires for needing the position of skid plate insertion deeper.

Another object of the present invention is to propose a kind of new skid plate (tearing tire hook open) component, not only solves above-mentioned skid plate The technical issues of not being adjustable operating position also improves the safety used.

In view of the various defects of above-mentioned existing vertical tyre disassembling devices, and into one on the basis of defective Step research and development, technical solution of the present invention provide a kind of novel vertical tyre disassembling devices, substantially shorten the height of column, make to take turns Operating position can be directed at tire centerline completely during tire disassembling operations, compact-sized, and operational motion is simple and convenient efficiently, operation Occupied area is small, and use is safe, durable.
