Extensively, this gives the manufacture of derrick crane, installs proposition requirement higher.Existing lifting arm brace device structure such as Fig. 1-3 institutes
Show, scheme of installation is as shown in figure 4, tower top is using sister block structure (shown in Fig. 5), when pull bar is installed, hoist rope（Fig. 4
Sequence number 4）Pass sequentially through tower top pulley I（Fig. 4 sequence numbers 1）, plate pulling device pulley（Fig. 4 sequence numbers 3）, tower top pulley II（Fig. 4 sequence numbers 1）Afterwards
It is fixed on the outer adjustable plate suspension centre of plate pulling device, starts raising structure, the company of plate pulling device and outer arm-tie in tower top is realized by bearing pin
Connect, due to outer adjustable plate（Fig. 4 sequence numbers 5）With interior adjustable plate（Fig. 4 sequence numbers 9）Type of attachment is non-removable structure type, because
This completes outer adjustable plate and tower top outer arm-tie（Fig. 4 sequence numbers 2）Fixation after, the position of interior adjustable plate is to maintain static, while
It is adjustable plate and tower top in realizing because the interference of pulley makes interior adjustable plate section to realize the fixation of steel wire rope and interior adjustable plate
Interior arm-tie（Fig. 4 sequence numbers 10）Fixation just can only be by connecting plate（Fig. 4 sequence numbers 8）Machining accuracy ensure, simultaneously because peace
It is work high above the ground during dress, is influenceed by complex working conditions such as wind loads, increase installation difficulty, influences the safety of operating personnel
Property.Therefore this kind of structure type presence is more expensive to manufacture, installation procedure is complicated, installation effectiveness is low, installation process security is low
The problems such as.
The content of the invention
The present invention proposes a kind of New crane arm brace plate pulling device structure, solves pull bar device manufacturing cost in the prior art
High, installation procedure is complicated, installation effectiveness is low, the low problem of installation process security.
The present invention is a kind of derrick runway girder pull bar plate pulling device structure design：It is made up of outer adjustable plate and interior adjustable plate, two
Person cancels plate pulling device pulley, connecting plate by hinge, and interior adjustable plate is adjusted to single plate structure, while by tower top pulley number
Amount reduces 1（As shown in Figure 7）, structure type is simple, low cost of manufacture；Steel wire rope suspension centre is set on short rod, is realized interior
The controllability of adjustable plate and flexibility, reduce installation difficulty, improve the security in installation process；Because plate pulling device is designed as
Dismountable structure type and suspension centre is set on short rod, can be according to crane arm, the weight of lifting arm brace and lifting mechanism
Lifting capacity be adjusted in lifting long draw and connect after, recurrence is hung short rod and is connected, thus with applicable ability it is strong, answer
Use extensive advantage.
Beneficial effects of the present invention are：The installation procedure of lifting arm brace can be simplified, manufacturing cost is reduced, improved and installed
The flexibility of process and efficiency, improve the security in installation process, while having the characteristics of being widely used.
