Description
Technical field
The present invention relates to a kind of hoisting crane, particularly relate to a kind of electric tyre crane.
Background technology
The principal feature of wheel-mounted crane is: its travel operator's compartment and lifting control cabin unites two into one, be developed by crawler crane (crawler crane) to form, the crawler belt of traveling gear and mobile roof support part are become the chassis having tire, overcome the shortcoming that crawler crane (crawler crane) caterpillar block road pavement damages, also comparatively crawler crane (crawler crane) is fast for the speed of traveling; Operation is stable, hoisting capacity large, can lift heavy walking in particular range.
In view of the plurality of advantages of wheel-mounted crane, it has been widely used in the lift heavy operation in the limited place of the miles of relative movement such as goods yard, harbour, building site, traditional wheel-mounted crane because of rotary column on it and turntable arrange unreasonable, there is the shortcoming that volume is large, manoevreability is poor.
Summary of the invention
The object of the present invention is to provide a kind of electric tyre crane, it is by the improvement to upper rotary column and operating mechanism, and the space that operating mechanism is taken is reduced, and manoevreability is good, to solve electric tyre crane Problems existing in prior art.
For reaching this object, the present invention by the following technical solutions:
A kind of electric tyre crane, it comprises underframe, the bottom of described underframe is provided with road wheel and supporting leg, turntable seat is installed on the top of described underframe, described turntable seat is arranged the turntable that the pedestal that rotates rotates, described turntable is arranged swing type mechanism, lifting mechanism, luffing mechanism and upper rotary column, and crane arm is installed in the side of described turntable, luffing assembly pulley is arranged on crane arm by upper rotary column, and the afterbody of described turntable is provided with balance weight, and described upper rotary column is Detachable propeller strut.
Especially, described Shears comprises upper bracket and lower bracket, the top of described upper bracket arranges pulley assembly, described upper bracket comprises the upper strut that upright top rod is connected with top rod with one end, described lower bracket comprises the lower supporting rod that upright lower link is connected by pipe link with top rod with top, the top of the bottom of described top rod and upper strut and lower link and lower supporting rod is corresponding offers through hole, bearing pin through through hole by upper bracket and the dismountable connection of lower bracket.
Especially, described lifting mechanism comprises electrical motor, speed reduction gearing, coupler and reel, described electrical motor is connected with speed reduction gearing by coupler, and described speed reduction gearing connects reel, and described speed reduction gearing installs drg relative to the opposite side connecting reel.
Beneficial effect of the present invention is, compared with prior art the luffing mechanism of described electric tyre crane, lifting mechanism and rotating mechanism are arranged on turntable, go up rotary column simultaneously and adopt dismountable Shears form, manoevreability is better in motion not only to make hoisting crane, and alleviates the deadweight of hoisting crane.
