Abstract

The utility model relates to a plane arm elevating, mobile arm distributing machine, composed of a movable arm type tower crane and a concrete distributing mechanism. The length of a slide rail arranged on a suspended arm penetrates through the head and the tail of the suspended arm; a slide rail arranged in front of a distributing pulley is provided with an elevating amplitude changing pulley 11; a pulley limiting locking device is arranged on a slide rail at the point where the distributing pulley can be away from the maximum limit distance of the center of rotation. The utility model has the advantages that when the plane arm elevating, mobile arm distributing machine is used as a crane, the suspended arm can not move to change the amplitude of the amplitude changing pulley to adequately incarnate the disadvantages of rapid amplitude changing and accurate amplitude changing of a plane suspended arm; when the plane arm elevating, mobile arm distributing machine is used as a distributor, the bowing and raising amplitude changing of the suspended arm can ensure that the dead zone of distributing can be eliminated.

Description

Plane arm elevating, mobile arm discharging machinery

The utility model relates to a kind of flat arm-type lifting, the dual-purpose machine of movable arm type cloth, belongs to construction machinery equipment.

Concrete pouring cloth mechanization during for the realization high-building construction has the concrete pump truck that is exclusively used in the building concrete cloth abroad, but owing to himself structure qualification, is difficult to high-building construction more than six layers is carried out cloth.

Chinese patent CN2132735Y provides a kind of " tower lifting, the dual-purpose machine of cloth ", this patent is that concrete distributing mechanism and pillar crane organically are combined as a whole, concrete can be delivered to body of the tower with high height, and can be to the whole working range zone that crane covered on arbitrary position with the coagulation handwoven cloth.This patent advantage is to have realized cloth automation on the highrise building, has improved the concrete pouring work efficiency, has reduced labor intensity, and has also opened up the new building machinery of dual-use simultaneously, has saved building costs.

But still there are following two weak points in above-mentioned patent, 1. cloth system hangs the dual-purpose machine that combines with flat arm, because arm can not be kicked up, just the action with the union elbow of cloth tube realizes the luffing of cloth tube by the luffing coaster on the arm, will cause like this to hang to become in the certain radius scope near the body and pour into a mould the cloth dead band; 2. cloth system hangs the dual-purpose machine that combines with swing arm, all to raise the action of bowing when then being cloth or lifting and realize luffing by arm, and often need back and forth luffing lifting on the sustained height work plane during building operations, the swing arm luffing action of hanging at this moment just can not show a candle to luffing quick action, the accuracy rate height that flat arm hangs.

The utility model purpose is: overcome the deficiency of prior art, provide a kind of can be fast when lifting, accurately luffing, the flat arm-type lifting that when cloth, can eliminate any dead band, the dual-purpose machine of movable arm type cloth.

Making dual-purpose function possess flat arm, two kinds of functions of movable arm type, how key can will put down arm-type luffing coaster locking, makes it to be unlikely from arm and come off when arm is kicked up if being to solve.

The utility model is achieved in that by swing arm pillar crane and concrete distributing mechanism to be formed, concrete distributing mechanism by concrete pump 1, the vertical conveying pipeline 2 parallel, with the fixedly cloth tube 5 of arm 6 synchronization actions with crane body of the tower 3, can constitute with respect to the

union elbow

4,8 that arm 6 takes place to be connected between the moving cloth pipe 10 of angular displacements and these three sections material pipes, supporting the fixedly cloth coaster 7 of union elbow 8 between the cloth tube 5 and moving cloth pipe 10 being equipped with vertically on the arm 6 to be equipped with on slide rail, the slide rail.Characteristics are: the length of slide rail runs through arm 6 head and the tail, a lifting luffing coaster 11 is housed on the slide rail in cloth coaster 7 the place aheads, can on the slide rail of tower crane centre of gyration greatest limit distance, be provided with the limitation locking device 9 of a luffing coaster 11 at cloth coaster 7.When realizing the utility model, the limitation locking device 9 of luffing coaster 11 can design like this: by two perpendicular to the stop pin 17 of slide rail 15 and one by rocking

arm

21,23 and

hinge

20,24, four bar-link drive of 25 three moving sets of three revolute pairs that constitute are formed; rocking arm 21; end of 23 is connected to a bit at hinge 20 places; the other end is at hinge 24; 25 places join with stop pin 17 ends respectively; joystick 14 is connected on the hinge 20 by control cord 25; can spur hinge 20 and be parallel to slide rail 15 to arm 6 Caudad displacements, and back-moving spring 19 head ends and the arm 6 that are parallel to slide rail 15 settings are affixed; tail end and hinge 20 join.

The utility model advantage is:

1. do the crane time spent, arm is motionless, utilizes the luffing coaster to realize the lifting luffing, can give full play to flat arm luffing advantage fast and accurately like this.

2. do the material distributing machine time spent, the action of raising bow action, luffing coaster and union elbow that can arm cooperates jointly to finish the cloth luffing, can guarantee all pourable cloth of any point in the arm coverage like this, eliminates the cloth dead band.

Fig. 1 is the utility model general structure schematic diagram.

Fig. 2 becomes secondary coaster locking device structure schematic diagram for the utility model.

Below in conjunction with drawings and Examples the utility model is done further narration:

As shown in Figure 1, the utility model is made up of concrete distributing system and movable arm type tower crane crane two parts, tower crane is by body of the tower 3, arm 6, luffing coaster 11 and limit locking device 9, suspension hook 12 is formed, cloth system by concrete pump 1, vertically conveying pipeline 2,

union elbow

4,8, fixedly cloth tube 5, cloth coaster 7, moving cloth pipe 10, cloth flexible pipe 13 are formed.

As the crane time spent,

cloth tube

5,10 to be pulled down from arm 6, arm 6 is no longer done and is raised the action of bowing, and this moment, whole crane promptly was the service behaviour of flat boom hoist, and the luffing action moves back and forth realization by luffing coaster 11 along slide rail on the arm 6.

As the material distributing machine time spent,

cloth tube

5,10 is connected, the cloth luffing is by the action cooperation realization that moving of the action of bowing, luffing coaster 11 reaches union elbow 8 of raising of arm 6.

As the material distributing machine time spent,

cloth tube

5,10 is connected, the cloth luffing is by the action cooperation realization that moving of the action of bowing, luffing coaster 11 reaches union elbow 8 of raising of arm 6.When arm 6 was kicked up, luffing coaster 11 certainly will come off for preventing itself and arm 6 to the Caudad slippage of arm 6, needed to start locking device 9.

As shown in Figure 2, locking device 9 is formed by two stop pins 7 and by four bar-link drive, joystick 14 and control cord 16, back-moving spring 19 that 20,24,25, two rocking arms 21,22 of three hinges are formed, and control cord 16 head ends and back-moving spring 19 ends all join with hinge 20.When starting locking device 9, as long as pull handle 14, tension control cord 16, then hinge 20 will overcome spring 19 pulling force and to arm 6 Caudad displacements, so rocking

arm

21,23 all pushes up two pins 7 to such an extent that lean out slide rail 15 respectively by

hinge

24,25, when gliding to being positioned to herein the time, pinned by coaster 11 like this, as if need not lock the time, as long as release handle 14, then under back-moving spring 19 effect, two pins 17 are just withdrawn again in the slide rail, so that coaster 11 just can slide by this point is without hindrance.
