Description
Technical field
The utility model relates to a kind of latching device, specifically a kind of for by Manual-pushing, the steamboat brake gear of wheel braking on the transhipment vehicle frame of four load-supporting wheel compositions (for example: manually carrier-and-stacker, Semi-Electric Stacker Trucks, heavy type moves chain-wales etc.).During use, equipment is walked by four-point supporting, by artificial support, holds moving velocity and direction, in direction control wheel, can join this device.In the time of whole equipment need to being stopped moving, latching device can be adjusted to locked position and reach whole equipment effect of braking.
Background technology
Like product in the market also adopts vertical type brake gear, and as shown in Fig. 1～2, this structure comprises: 1 ', brake pedal; 2 ', brake cam; 3 ', pedal shaft; 4 ', brake mount; 5 ', top emits nut; 6 ', fastening screw nut; 7 ', installation chassis; 8 ', bracket arm; 9 ', retracing spring; 10 ', Universal castor; 11, locking plate.During use, step on brake pedal, brake cam rotates and to pressing down bracket arm, the locking plate of bracket arm end is attached to, and realizes brake.The latching device of this structure has the following disadvantages: many, the structure relative complex of spare and accessory parts quantity needing, and monnolithic case is huge, affects to a certain extent whole product appearance, has increased apparent size.
Another kind of brake mode only depends on the friction braking of wheel outside face and brake facing, not good for heavy lift situation braking effect.Batch manufacturing is made needs mould to guarantee size, and use cost is too high.
Utility model content
The purpose of this utility model is to provide a kind of steamboat brake gear, has overcome the above-mentioned deficiency of prior art, and its structure is simpler, and part assemblies number is more simplified, and oad dwindles, more reasonable structure, and profile is more attractive in appearance; Braking effect is good, operates simpler.
In order to reach above-mentioned design goal, the technical solution adopted in the utility model is as follows:
A kind of steamboat brake gear, comprise installation chassis, brake cam, brake wheel carrier, positioning screw, retracing spring, locking plate, the described installation chassis downside wheel that is coupling, brake wheel carrier is fixed on installation chassis and axletree, the position that described brake wheel carrier extends wheel is by the cam shaft brake cam that is coupling, brake cam is the stretcher that an eccentric wheel and one side are provided with integrative-structure, between described brake cam and wheel, be provided with positioning screw, positioning screw is socketed on screw rod frame, screw rod frame is structure as a whole with brake wheel carrier, socket retracing spring in described screw rod frame, positioning screw is set in retracing spring, described positioning screw end is by nut interlocking locking plate.
Preferably, described positioning screw axle center vertical passing through in axletree and cam shaft respectively.
Preferably, in described screw rod frame, be provided with limit dais, retracing spring one end overhead is on limit dais, and other end overhead is on the nut of positioning screw.
Preferably, described locking plate is arcuate structure, and its concave profile is identical with tire exterior arc surface.
Preferably, described positioning screw end locking is at locking plate middle part.
The beneficial effect of steamboat brake gear described in the utility model is: change vertical type into angle-inserting type, installation site is rotated to an angle around core wheel, brake system is dwindled and ensconced under whole train adapter plate.Saved locus, accessory size compared with complexity vertical type want succinct a lot.During braking, because the axis of positioning screw passes core wheel, during locking plate compressing wheel, the precompressed compression while becoming friction drag generation completely because of the effect stopping power of axle core.While comparing vertical type braking, the braking of cardan wheel, has reduced the waste of precompressed compression component, and braking effect is better.
Structure is simpler, and part assemblies number is more simplified, and vertical type is 11 parts, and angle-inserting type is 7 parts; Cancelled part-structure on installation chassis, all system contracts below installation chassis, and oad dwindles, more reasonable structure, and profile is more attractive in appearance; By cam and stretcher part, wheel carrier and positioning screw guiding position, adopt precision casting process to unite two into one, reasonable combination design of part; Braking effect is good, operates simpler.

The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the utility model is described in further detail.
As shown in Figure 3-4, steamboat brake gear described in the utility model embodiment, comprise installation chassis 1, brake cam 2, cam shaft 3, brake wheel carrier 4, positioning screw 5, retracing spring 6, locking plate 7, screw rod frame 9, the described installation chassis 1 downside wheel that is coupling, brake wheel carrier 4 is fixed on installation chassis 1 and axletree, the position that described brake wheel carrier 4 extends wheel is by cam shaft 3 brake cam 2 that is coupling, brake cam 2 is the stretcher 8 that an eccentric wheel and one side are provided with integrative-structure, between described brake cam 2 and wheel, be provided with positioning screw 5, positioning screw 5 is socketed on screw rod frame 9, the integrative-structure that screw rod frame 9 and brake wheel carrier 4 are casting, the interior socket retracing spring 6 of described screw rod frame 9, positioning screw 5 is set in retracing spring 6, by retracing spring 6, can make positioning screw 5 automatically reset when without External Force Acting, described positioning screw 5 ends are by nut interlocking locking plate 7, locking plate 7 is arcuate structure, and its concave profile is identical with tire exterior arc surface.
Described positioning screw 5 axle center are vertical respectively makes positioning screw 5 moving directions vertical all the time with axletree by axletree and cam shaft 3, guarantees that the locking plate 7 of positioning screw 5 ends is more firm with wheel self-locking.
In described screw rod frame 9, be provided with limit dais, retracing spring 6 one end overheads are on limit dais, and other end overhead is on the nut of positioning screw 5, when compression set screw rod 5, retracing spring 6 shrinks together, and during without external force, under retracing spring 6 effects, positioning screw 5 is realized and being resetted.
Described positioning screw 5 ends lock at locking plate 7 middle parts, make locking plate 7 stressed more even.
Described brake cam 2 is precision cast part with brake wheel carrier 4, global formation, and productive costs is lower, longer service life.
During locking, firmly step on pedal position on brake cam, brake cam will rotate around cam shaft.Because cam is eccentric structure, can be increasing from rotating shaft distance with positioning screw contact site, promote positioning screw and move down along brake wheel carrier chute, retracing spring is compacted simultaneously.Positioning screw drives locking plate to press to wheel axle core, makes wheel produce a small amount of crimp to shaft core direction, and cam pressure has been delivered on locking plate completely, has increased the precompressed compression of locking plate and wheel surface, and friction force increases afterwards, good braking effect.No matter cam is when which kind of state, and the direction of application force is all the time through cam shaft center, makes like this cam all can self-locking in any position, in the situation that there is no external force, can resilience stretcher, and remain braking mode.
While needing loosen the brake, with tiptoe, at stretcher lower position, upwards lift gently, under the promotion of retracing spring, brake cam is around cam shaft contrarotation.Locking plate leaves wheel under positioning screw drives, and gets final product loosen the brake.
Above embodiment is only exemplary, and under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment, and these improvement or distortion drop in protection domain of the present utility model.It will be understood by those skilled in the art that specific descriptions are above in order to explain the purpose of this utility model, not for limiting the utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
