Description
Technical field
The utility model relates to a kind of self-powered platform, is a kind of self-powered platform of collapsible, hand-operated lifting specifically.
Background technology
In flight-line maintenance, when particularly servicing a car, the height of table of place tool needs to regulate at any time to satisfy maintenance requirements, and the workbench of traditional lifting can only in the situation that zero load transfers to suitable height by manual with workbench, use comparatively inconvenience.Existing self-powered platform is divided into hand-operated lifting and automatic lifting, the applicant is the disclosed self-powered platform of CN200820237923.9 in the patent No. of first to file, coordinate the fastening nut of fall way to make scratch diskette with the fall way lifting by the column upper groove, lock simultaneously the fastening nut and control the scratch diskette level altitude, its weak point is: this tool shelf must manually raise with the down tools dish after locking fastening nut, descending operation is loaded down with trivial details, wastes time and energy; Also having the patent No. is the disclosed Pneumatic type lifting working bench of CN200920045506.9, and the lifting of tool shelf is to be realized by air pump take off and landing strip power driven tools dish, breaks down as air pump, workbench can't lifting, use and security performance are low, change, keep in repair trouble, and cost is high.
Summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of compact conformation, lifting is convenient, security performance is high, the self-powered platform of failure rate is low, long service life.
The technical solution adopted in the utility model is: a kind of self-powered platform, comprise tool shelf, underframe, fall way, column, the tool shelf lower surface connects fall way, fall way is placed in column, column is vertically connected on underframe, the underframe lower end is provided with universal wheel, it is characterized in that: described fall way sidewall is provided with tooth bar, described column is provided with lowering or hoisting gear, be provided with gear and ratchet in lowering or hoisting gear, the wheel and rack engagement, gear is provided with rotating handles, the afterbody of described ratchet is provided with the retaining control stick, and the pawl head of ratchet is stuck on the tooth mouth of tooth bar.When tool shelf must rise, shake rotating handles, the gear drive tooth bar makes fall way drive the tool shelf rising, continue in uphill process at tooth bar, the ratchet pawl head that the rack tooth mouth will be stuck in the tooth mouth upwards pulls away the tooth mouth, and tooth bar is not affected by ratchet pawl head, and fall way can normally rise; When tool shelf must descend, the retaining control stick of leaving behind unclamps ratchet made ratchet pawl head break away from the tooth mouth of tooth bar, oppositely shakes rotating handles, the gear drive tooth bar makes fall way drive tool shelf decline, in tooth bar continuous decrease process, ratchet pawl head descends without impact on tooth bar, and fall way can normally descend; The tool shelf descending operation is simple, convenient, need not manually lift or press tool shelf, and is time saving and energy saving; By rotating handles operation gear driven gear rack elevating, compact conformation, the mechanical elevating reliable in structure, failure rate is low, easy to maintenance, long service life.
Further, also be provided with the spring of pressing ratchet pawl head in described lowering or hoisting gear.When tool shelf rose, the ratchet pawl head that fall way rack tooth mouth will be stuck in the tooth mouth upwards pulled away the tooth mouth, and reset of card is to next tooth mouth under the effect of spring for ratchet pawl head, and rack tooth is salty upwards pulls away the tooth mouth with ratchet pawl head again, and fall way can normally rise; After the tool shelf rising stopped, ratchet pawl head is static being stuck in the tooth mouth under the effect of spring, avoids tooth bar to glide and make tool shelf decline cause contingency, improved the workbench usage safety performance.
Again further, described tool shelf lower end is fixedly connected with free bearing, free bearing is provided with the arc orbit groove, described fall way top is provided with lock-screw, the bolt part of lock-screw is placed in the arc orbit groove of free bearing and can slides in the arc orbit groove, the nut of lock-screw partly compresses free bearing and fall way, and the fall way upper articulation is on the pin joint of free bearing, and fall way can rotate around pin joint along arc orbit groove direction; Described arc orbit groove is 1/4 circle take pin joint as the center of circle.The arc orbit groove of tool shelf lower end free bearing is rotated around pin joint, lock upper lock-screw after turning to the required angle of tool shelf, make the whole table top of tool shelf fixing at an angle towards the user, when placing some less parts, user's use of can differentiating clear, intuitively and take, when avoiding the conventional tool card to be horizontally disposed with, the user can't find the drawback of required part at a glance, has improved operating efficiency; The arc orbit groove of tool shelf lower end free bearing takes up room after the folding gathering of tool shelf little after pin joint rotates 1/4 circle, is convenient to deposit, transport.
The utility model adopts lowering or hoisting gear gear engagement fall way gear rack elevating tool shelf, and engagement tool dish lower end is connected to the movable Foldable tool dish of free bearing, compact overall structure, lifting, folding convenient, security performance is high, failure rate is low, long service life stores convenient transportation.
