Abstract
The utility model relates to a lifting and distributing two-purpose tower crane. A distributing system is additionally arranged on a tower crane, a detachable auxiliary tower top is arranged on the side face of a main tower top of a tower body, and a distributing hoist which can drive a wire rope pulley block to move is arranged on the rear part of a rotating platform. The root of a distributing arm I is hinged on the rotating platform and is coincidently provided with a rotating tower body, and the other end of the distributing arm I is successively hinged with a distributing arm II and a distributing arm III. Hinged points of the distributing arm II and the distributing arm III are hinged on the lower part of a distributing cart, the distributing arm I is driven by the distributing hoist, the following movement of the distributing arm II can be realized, and the distributing arm III is driven by an oil cylinder. Work high above the ground is not needed when the utility model realizes lifting and distributing conversion, and maximum scale distribution can be realized under the condition of no influence to lifting performance.
Description
The utility model relates to a kind of hoist tower machine, particularly lifting, cloth double-duty tower machine.
Existing lifting, cloth double-duty tower machine mainly contain following three kinds: 1, lay cloth tube under last turn arm arm frame of tower crane, give the jib lower boom by the cloth trolley with cloth pipeline weight transfer.Carrying the front end of boom moving part with load hook,, changing the cloth radius and realize cloth by bow the lifting with suspension hook of facing upward of crane arm.Though inferior scheme can have been utilized cat head, the jib of tower machine, the load-carrying properties of turntable.But when lifting, two kinds of change working of cloth, the cloth pipeline must be unloaded, cause transfer time long, and the necessary aloft work of personnel, danger is bigger, inconvenience.2, install the crank block type cloth system of forming by three joint cloth arms, two driving oil cylinder and a cover cloth trolley additional in last revolution device of carriage amplitude varying tower crane turntable one side.This scheme shortcoming be cloth system huge, from great, two lower booms of crane arm stressed extremely unreasonable, the cloth radius is little, less economical.3, in last revolution device of carriage amplitude varying tower crane elevator boom rack, lay cloth tube.Jib is four sections hinged truss formulas, and a joint arm maintains static, and two joint arms are driven by one group of wire rope pulley group.Three joint arms and four joint arm rest Driven by Hydraulic Cylinder realize cloth.Though this scheme cloth radius strengthens, moment is excessive, conversion needs aloft work, the long shortcoming of required time to exist lifting working condition to lean forward.
The purpose of this utility model provides a kind of lifting, cloth double-duty tower machine, and the conversion of lifting, cloth need not aloft work, and can realize cloth significantly not influencing under the lifting performance prerequisite.
The technical solution of the utility model: the cloth system attaching of this double-duty tower machine is on the tower machine, by three joint cloth arms, the cloth trolley, power system and concrete pipeline system are formed, it is characterized in that: the side on body of the tower king-tower top is provided with detouchable secondary tower top, be provided with the cloth elevator that drives the motion of wire rope pulley group at the turn table rear portion, cloth arm I root is hinged on the turn table, overlap layout with slewing tower, the other end and cloth arm II and cloth arm III are hinged successively, the hinge of cloth arm II and cloth arm III is articulated in the below of cloth trolley, cloth arm I is driven by the cloth elevator, cloth arm II servo-actuated, cloth arm III is by hydraulic oil cylinder driving.
Above-mentioned secondary tower top, cloth elevator, wire rope pulley group constitute steel rope elevator system, and with cloth arm I, cloth arm II and cloth arm III in same plane of constraint.
The hinge of above-mentioned cloth arm II and cloth arm III is articulated in the below of cloth trolley by suspender.
Above-mentioned cloth trolley can slide along the crane arm longitudinal axis.
Above-mentioned when the user does not need the cloth function, cloth system and secondary tower top can be installed, reduce by a joint slewing tower, the double-duty tower machine just becomes the tower crane of standard form.
Working process of the present utility model: main mode of operation is the lifting state.When lifting work finishes, in the time of need entering cloth work, load hook 1 is risen to highest point, crane carriage 2 is delivered to crane arm 3 foremost, and the function switch in the driver's cab is got to " cloth " shelves, and cloth system can be devoted oneself to work.When cloth elevator 11 is put rope, cloth arm I8 by gravity is around the dead axle bottom, cloth arm 7 is made plane motion, cloth trolley 5 promotes lower edge crane arm 3 at cloth arm II7 and slides, cloth arm III4 around the dead axle swing, promptly just can adjust the cloth position by the action of control cloth elevator 11 and hydraulic ram 6 under hydraulic actuating cylinder 6 promotes.When the cloth end, in the time of need entering lifting work, primer fluid compressing cylinder 6 closes up cloth arm III4 and cloth arm II7; Cloth elevator 11 is received rope, and cloth arm I8 draws close to secondary tower top 15 under the effect of cloth arm assembly pulley 9; Cloth arm II7, III4 draw close from trend cloth arm 8 simultaneously, and cloth trolley 5 also inwardly slides along crane arm 3 automatically, behind limit position, cloth arm I8 and secondary tower top 15 automatic positive locks, cloth elevator 11 outage, cloth arm 7,4 and cloth arm 8 close up, and cloth trolley 5 falls back on the root of crane arm 3.Function switch in the driver's cab is got to " lifting " shelves, and tackling system can be devoted oneself to work.
Advantage of the present utility model: this machine has possessed and two kinds of functions of cloth simultaneously, sliding opinion group by the cloth elevator that is located at the turn table rear portion by cloth arm steel rope because of the dead axle swing of cloth arm I drives, made full use of the comprehensive load capacity of tower machine crane arm, cat head and turntable, the deadweight that has alleviated cloth system greatly; The lower end bending of cloth arm I with to overlap the bearing of arranging with slewing tower on turn table hinged, do not increase the turn table size, and has greatly reduced the lateral deviation load on the tower machine, on the turntable, counterweight need not be set can guarantee that jacking adds High Performance; The hinge of cloth arm II and cloth arm III is articulated in the below of cloth trolley by suspender, guaranteed that two lower booms of crane arm evenly carry, do not bear moment of torsion, make crane arm just the same at the stress form of cloth operating mode and lifting operating mode, improved the stressed of crane arm greatly, increased the cloth amplitude and do not lost lifting performance; Lifting, cloth change working are all finished by driver operation in driver's cab, need not artificial aloft work, change safe, quick and easy, the capacity utilization rate height, equipment handover charge reduces, and cement concrete can directly be delivered to the pour point continuous pouring, the operating efficiency height, quality is good.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is an integral structure scheme drawing of the present utility model, and Fig. 2 is that Figure 1A is to lateral plan;
Fig. 3 is the hinged scheme drawing of cloth arm, and Fig. 4 is Fig. 3 A-A section-drawing;
