Background technology
Along with the fast development of building construction technology, for colony's building and highrise building, generally adopting towed concrete pump car or concrete mixer is the job site delivering concrete.Concrete mixer has and advantage such as moves flexibly, convenient; But it is more restricted that its shortcoming is the cost height, delivery head is compared towed concrete pump; The towed concrete pump car then has advantage simple in structure, that cost is low, and delivery head to compare concrete mixer much higher.At present, for the highrise building that is higher than 80 meters, concrete mixer also is difficult to transmission and concrete transmission to this height, and is opposite, and the towed concrete pump car highrise building more than 80 meters of then can constructing has clear superiority than concrete mixer on delivery head.
During towed concrete pump car delivering concrete; Usually also need be fixed on the boom of fixed material distributing machine through concrete conveying pipe; And be fixedly connected with towed concrete pump, fixed material distributing machine is again through jib each construction point delivering concrete in the scope of its permission.Notification number is that the Chinese patent of CN101446134 B is put down in writing, and the material distributing machine that a kind of jib horizontal rotation combines with elevating movement a kind ofly exactly is fixedly connected through conveyance conduit, relies on the construction machinery of towed concrete pump car delivering concrete.In this patent, the revolution of its material distributing machine realizes that through the first horizontal rotation mechanism on the base or the second horizontal rotation mechanism pitching then realizes through the stretching of the oil cylinder on the middle arm.In this structure, the junction of respectively saving arm in the jib can only be realized facing upward and bowed or turn round single function, comparatively speaking, its structure or more complicated, cost is also higher.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure and simultaneously can realize facing upward and bow and the jib of revolute function and have the concrete spreader of this jib.
In order to achieve the above object; A technical scheme of the present invention has provided a kind of concrete spreader jib; Comprise first boom and second boom, be connected with conveyance conduit between first boom and second boom, it is characterized in that: the end at first boom is provided with the first horizontal rotation mechanism; But in the first horizontal rotation mechanism, be provided with the swiveling head of horizontal rotation, the front end of second boom and swiveling head flexibly connect and make second boom vertically to rotate.
Preferably, an end of first oil cylinder is connected on second boom, and the other end is connected oil cylinder horizontal rotation mechanism, and oil cylinder horizontal rotation mechanism is fixed on first boom.
Preferably, said oil cylinder horizontal rotation mechanism is fixed on said first boom through bearing support.
Preferably, link to each other through first bearing pin between the front end of said second boom and the said swiveling head, said second boom vertically rotates around first bearing pin.
Preferably, in the said first horizontal rotation mechanism, be provided with mechanical lock in order to its horizontal rotation of locking.
Preferably, said swiveling head props up through horizontal rotation and stays in the said first horizontal rotation mechanism.
Another technical scheme of the present invention has provided a kind of concrete spreader with above-mentioned concrete spreader jib; Comprise column; Be provided with the second horizontal rotation mechanism on the column top; It is characterized in that: flexible connection makes the concrete spreader jib vertically to rotate between the front end of said concrete spreader jib and the second horizontal rotation mechanism, and an end of second oil cylinder is connected in the second horizontal rotation mechanism, and its other end is connected on the said concrete spreader jib.
Preferably, link to each other through second bearing pin between the front end of said concrete spreader jib and the second horizontal rotation mechanism, said concrete spreader jib vertically rotates around second bearing pin.
A kind of concrete spreader jib provided by the invention is not only simple in structure, and the junction of respectively saving arm can be realized simultaneously facing upward and bowed and turn round.Adopt its cost of concrete spreader of a kind of concrete spreader jib provided by the invention also to obtain better controlled.
Description of drawings
Fig. 1 is the structural representation of a kind of concrete spreader among the embodiment;
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; The invention provides a kind of concrete spreader; Comprise column 13, be provided with the second horizontal rotation mechanism 14, make the concrete spreader jib vertically to rotate through 15 flexible connections of second bearing pin between the front end of concrete spreader jib and the second horizontal rotation mechanism 14 on column 13 tops; One end of second oil cylinder 5 is rigidly attached in the second horizontal rotation mechanism 14, and its other end is rigidly attached on the said concrete spreader jib.
Wherein, In conjunction with Fig. 2; The concrete spreader jib comprises on first boom 1 and second boom, 2, the first booms 1 and second boom 2 and the junction is provided with conveyance conduit 9, is provided with the first horizontal rotation mechanism 3 at the end of first boom 1; But the mechanical lock 7 that the swiveling head 8 that in the first horizontal rotation mechanism 3, is provided with horizontal rotation reaches in order to its horizontal rotation of locking; Swiveling head 8 supports 6 through horizontal rotation and is located in the first horizontal rotation mechanism 3, and the front end of second boom 2 flexibly connects with swiveling head 8 through first bearing pin 11 and makes second boom 2 vertically to rotate, and an end of first oil cylinder 4 is rigidly attached on second boom 2; The other end is rigidly attached to oil cylinder horizontal rotation mechanism 10, and oil cylinder horizontal rotation mechanism 10 is fixed on first boom 1 through bearing support 12.
In the present invention, when first oil cylinder 4 stretched or withdraws, second boom 2 can be realized facing upward thereupon and bow.Simultaneously, swiveling head 8 combines oil cylinder horizontal rotation mechanism 10 again through the first horizontal rotation mechanism 3, can second boom 2 realize facing upward bow in, drive second boom, 2 horizontal rotations.
Whole concrete spreader jib is realized horizontal rotation through the second horizontal rotation mechanism 14, through the rotation on second oil cylinder 5 and second bearing pin, the 15 realization vertical directions.
