Description
Technical field
It the utility model is related to lifting lowering or hoisting gear field, and in particular to a kind of gear rack elevating machine.
Background technology
The lifting device used at present, most of using motor transmission or hydraulic drive, on the one hand consuming electric energy, another
The complicated maintenance difficult of aspect.Motor is lifted, and then realize that lifting is flat as power using steel wire rope to hoistable platform
The lifting of platform.If shutdown suddenly or failure occurs in motor in lifting process, easily there is hoistable platform and drop, safety occur
Accident.The piston of hydraulic cylinder is typically directly connected as power, is realized and risen by the lifting of piston by hydraulic pressure with hoistable platform
The lifting of platform is dropped, and because hydraulic cylinder is designed with safety valve, when hoistable platform overloads, the safety valve of hydraulic cylinder is opened, and now can
There is the situation of hoistable platform landing, security incident occur.And traditional hydraulic lifting can not stop quasi- system for a long time, it is used
Scope is substantially reduced.
The content of the invention
It is of the present utility model mainly for the deficiencies in the prior art, there is provided it is a kind of it is simple in construction, be easy to repair, rack and tooth
Good, the difficult for drop-off rack elevator of wheel engagement effect.
Above-mentioned technical problem of the present utility model is carried out by the following technical programs：
A kind of rack elevator, including runners, the support bar being arranged on runners, elevating lever is arranged with support bar, rise
The top of drop bar is provided with rack, rack is provided with described elevating lever, the end set of support bar has gear mechanism, institute
The gear mechanism stated includes gear, handle and is connected to rocking handle on handle, and described wheel and rack engagement, described handle passes through
Wear the center of the gear in gear mechanism.Shake rocking handle and drive pinion rotation, because gear engages with elevating lever upper rack,
Therefore in the engineering for shaking rocking handle, elevating lever moves upwards；Moved downward conversely, opposite direction shakes rocking handle elevating lever, so as to
Realize the function of lifting.
Preferably, being additionally provided with safety lock on described gear mechanism, the locking plate of safety lock can be inserted into rack.Locking plate
Insert in rack, engaging can be played a part of, improve security.
Preferably, the top of elevating lever is provided with handle reverse between described rack and elevating lever.Turn over
Changing hands the setting of handle can allow article is more convenient to place on rack.
Preferably, described rack is " work " font.It is easy to place article.
Preferably, described runners is made up of three foot levers, the end set of foot lever has universal wheel, wherein a foot lever
On be provided with opening and closing part, opening and closing part connects other two foot levers by connecting rod.The setting of opening and closing part can at utmost strut three
Foot lever, improve stability.Universal wheel facilitates the movement of elevator.
Preferably, described rocking handle is " L " type.It is easy to holding rocking handle to be shaken.
In summary, the utility model compared with prior art, has advantageous effect in that：The utility model passes through tooth
Bar is engaged to realize that lifting is more stable, reliable with gear, in order to further improve the security during use, is increased
Safety lock is added.Generally speaking, the utility model is simple in construction, has a safety feature.
