Abstract
The utility model discloses a kind of Novel tower machine balance arm pull rod structure thereof, comprise single pull bar group (11) and triangle transition structure (1), described triangle transition structure (1) is formed by connecting primarily of a crossbeam (2), two symmetrical bending plates (3), described crossbeam (2) two ends connect equilibrium arm both sides suspension centre respectively, one end of junction cylinder lever connecting rod group (11) of two described bending plates (3), the other end of pull bar group (11) connects tower top.It is simplex pull rod group structure that tower machine balance arm pull rod structure thereof realizes duplex pull rod group Structural Transformation by triangle transition structure, improve its comformability and tolerance, avoid due to cumulative errors reasons such as associated components manufactures, the two groups of pull bar group Length discrepancy phenomenons caused, significantly improve its packaging efficiency, reduce cost of labor.
Description
Technical field
The utility model relates to a kind of Novel balance arm brace structure, is particularly useful for tower machine.
Background technology
At present, existing tower machine balance arm pull rod structure thereof is duplex pull rod group version (Fig. 1), pull bar group (11) is combined for multiple sectional type pull bar bearing pin, tower machine equilibrium arm and tower top agent structure is made to couple together and ensure the structure of equilibrium arm normal working, its one end is connected otic placode respectively and is connected with equilibrium arm, the other end is crossed by connecting panel (12), and is connected with tower top.Two groups of pull bar groups are assembled respectively, use side by side simultaneously.Often organize the pull bar group difference according to equilibrium arm size and hoisting point position relatively, carry out the piecewise combination of right quantity, and every root segmentation pull bar length differs.Therefore, this duplex pull rod group version is installed and used in process at tower machine, and pull bar quantity is many, and built-up time is long, efficiency is low, and cost of labor is high; And due to cumulative errors reasons such as equilibrium arm manufactures, easily cause two groups of pull bar group Length discrepancy phenomenons, equilibrium arm structures slope, fugitiveness are increased.
Summary of the invention
The defect existed for this version or deficiency, for reducing numerous and diverse degree of its assembling process, and avoid the two groups of pull bar group Length discrepancy phenomenons because the accumulated errors such as associated components manufacture cause, therefore the novel a kind of Novel balance arm brace structure of utilitarian design.
For achieving the above object, the utility model provides a kind of Novel tower machine balance arm pull rod structure thereof, by trigonometric expression transition structure, equilibrium arm both sides suspension centre is connected with simplex pull rod group, and then is transformed to simplex pull rod group structure.It comprises single pull bar group and triangle transition structure, described triangle transition structure is formed by connecting primarily of a crossbeam, two symmetrical bending plates, described crossbeam two ends connect equilibrium arm both sides suspension centre respectively, one end of the junction cylinder lever connecting rod group of two described bending plates, the other end of pull bar group connects tower top.
Further, described pull bar group adopts a plurality of sectional type pull bar bearing pin to combine.
Equilibrium arm pull bar new structure is simplex pull rod group version owing to making duplex pull rod group Structural Transformation, and decrease pull bar group quantity, packaging efficiency significantly improves, and thus has following advantage: 1, novel structure.Under guarantee usage condition, break conventional pull bar type of attachment; 2, built-up time is short, efficiency is high.Pull bar group quantity reduces relatively, simple installation, quick, and built-up time significantly shortens, and efficiency significantly improves, and cost of labor reduces; 3, strong adaptability.Tolerance is strong, avoids due to cumulative errors reasons such as associated components manufactures, the two groups of pull bar group Length discrepancy phenomenons caused.

Fig. 2 be in Fig. 1 A to rotate structural representation;
Fig. 3 is structural representation of the present utility model;
Fig. 4 be in Fig. 3 B to rotate structural representation;
In figure: 11, pull bar group, 12, connecting panel, 1, triangle transition structure, 2, crossbeam, 3, bending plate, 4, bearing pin.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 3, the utility model equilibrium arm pull bar new structure comprises single each pull bar group 11 and triangle transition structure 1, described triangle transition structure 1 is formed by connecting primarily of a crossbeam 2, two symmetrical bending plates 3, described crossbeam 2 two ends connect equilibrium arm both sides suspension centre respectively, one end of the junction cylinder lever connecting rod group 11 of two described bending plates 3, the other end of pull bar group 11 connects tower top, avoids the two groups of pull bar group Length discrepancy phenomenons because the accumulated errors such as associated components manufacture cause.
Described pull bar group 11 adopts a plurality of smallclothes such as sectional type pull bar bearing pin 4 grade to be connected and combines, and then is formed as simplex pull rod group 11 structure, according to unit design length requirement and simple installation, carries out the piecewise combination design of pull bar.
By applying this technology, XGT500(7550) type tower machine balance arm pull rod structure thereof realizes duplex pull rod group 11 Structural Transformation by triangle transition structure 1 is simplex pull rod group 11 structure, improve its comformability and tolerance, avoid due to cumulative errors reasons such as associated components manufactures, the two groups of pull bar group 11 Length discrepancy phenomenons caused, significantly improve its packaging efficiency, reduce cost of labor, meet human oriented design requirement, achieve good effect.
