A kind of jib, including rotary table and large arm, one end of described large arm is hinged with described rotary table, and
Described large arm can rotate in perpendicular relative to described rotary table, away from described time in described large arm
One end of turntable is hinged with forearm, and described forearm can rotate in perpendicular relative to described large arm,
It is characterized in that, being hinged with pull bar on described rotary table, described pull bar is away from one end of described rotary table
Hinged with described forearm, described rotary table, described large arm, described forearm and described pull bar constitute four even
Linkage.
Preferably, described pull bar is hinged specifically, in institute away from one end and the described forearm of described rotary table
Stating and be provided with balance base on forearm, described balance base is arranged on the upside of described forearm, described pull bar away from
One end of described rotary table is hinged with described balance base.
Preferably, described pull bar and described balance base are hinged away from one end of described forearm.
Preferably, described rotary table is hinged with pull bar specifically, fixedly mount on described rotary table
Having pull bar mounting seat, described pull bar is hinged with described pull bar mounting seat.
Preferably, described pull bar is hinged away from one end of described rotary table with described pull bar mounting seat.
Preferably, described large arm hollow vertically arrange so that described pull bar, described balance base and
Pull bar mounting seat all can be placed in described large arm.
This utility model also provides for a kind of concrete spraying vehicle, and described concrete spraying vehicle have employed said arm
Frame.
The jib that this utility model provides, is hinged with pull bar on rotary table, and pull bar is away from the one of rotary table
Holding hinged with forearm, rotary table, large arm, forearm and pull bar constitute quadric chain.Rotate in large arm
At the beginning of, forearm is in level, and when large arm carries out pitching, i.e. large arm carries out turning relative to rotary table
Dynamic, hinged with rotary table, forearm respectively due to pull bar, therefore, during large arm rotates, pull bar
Also can rotate identical angle relative to rotary table, collateral security forearm is in level all the time.Again owing to using
Large arm is as the effect of the connecting rod in quadric chain, therefore, and rotary table, large arm, forearm and draw
The stabilized soil pavement tool that bar constitutes quadric chain is good.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality
Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below,
Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art
From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is in structural representation during level for this utility model embodiment offer jib；
Fig. 2 is in structural representation during nutation state for this utility model embodiment offer jib；
Fig. 3 provides jib to be in structural representation when facing upward state for this utility model embodiment；

Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the application, below in conjunction with
Accompanying drawing in the embodiment of the present application, clearly and completely retouches the technical scheme in the embodiment of the present application
State, it is clear that described embodiment is only some embodiments of the present application rather than whole enforcement
Example.Based on the embodiment in the application, those of ordinary skill in the art are not before making creative work
Put the every other embodiment obtained, all should belong to the scope of the application protection.
The most as shown in Figure 1 to Figure 3, this utility model embodiment provides a kind of jib, including rotary table 1
With large arm 2, one end of large arm 2 is hinged with rotary table 1 logical, and large arm can be relative to rotary table 1 perpendicular
Straight rotation with in surface, in large arm 2, the one end away from rotary table 1 is hinged with forearm 3, and forearm 3 can be relative
Rotate in perpendicular in large arm 2, wherein, rotary table 1 be hinged with pull bar 4, pull bar 4 away from
