In prior art, the material of otic placode adopts dead-soft steel usually, and as a further improvement on the present invention, described monaural plate and described bi-lug plate adopt high strength steel, while proof strength, reduce otic placode weight.
To sum up, compared with prior art, the present invention selects single bi-lug plate transition to be connected with tower top by pull bar, eliminate baroque arm-tie assembly, simplify connection mode while meeting in-use performance, be convenient to vertical tower is installed, reasonably design the length of single, double otic placode simultaneously especially.Its advantage is as follows:
1, version is simple, and production and processing is convenient.Arm-tie instead of complicated arm-tie kit form, and structure is simple, improves the production cycle, reduces productive costs, improves the efficiency of production and processing.
2, installation, convenient disassembly.Do not need pretty troublesome original arm-tie assembly lifting being installed to tower top place when installing, dismantling, improve installation effectiveness yet.
The present invention also provides a kind of crane arm being provided with above-mentioned crane arm Tiebar structure.Because above-mentioned crane arm Tiebar structure has above-mentioned technique effect, therefore, the crane arm being provided with this Tiebar structure also should possess corresponding technique effect.
In addition the present invention's also a kind of hoisting crane being provided with above-mentioned crane arm, this crane arm is removably connected to described hoisting crane.Equally also should possess above-mentioned corresponding technique effect.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of crane arm Tiebar structure, crane arm and hoisting crane, convenient installation, connection mode of optimizing structure, reduces installation, manufacturing cost,
To achieve these goals, a kind of crane arm Tiebar structure of the present invention, comprises monaural plate, bi-lug plate, adapter shaft, and barrier parts; Described bi-lug plate is positioned at inside tower top, and bi-lug plate two ends are provided with two groups of corresponding connecting bores; Described monaural plate is between bi-lug plate, and monaural plate two ends are provided with connection hole; Three is connected with the connecting bore on monaural plate through tower top, bi-lug plate by described adapter shaft; Described barrier parts are arranged between bi-lug plate both sides and tower top.
Bi-lug plate is arranged on inside tower top, and and have space between tower top, vibration is produced in crane job, the bi-lug plate on adapter shaft and monaural plate can be made to rock, in order to prevent the generation of rocking, barrier parts are installed between bi-lug plate both sides and tower top, as further scheme of the present invention, these barrier parts are spacer, and spacer is set on adapter shaft, fill up the space between bi-lug plate and tower top.
