Existing crane boom head anti-twisting equipment is detachable movable type, main by axle connection, as shown in Figure 1 and Figure 2, welds two pieces of punching otic placodes, be arranged in two otic placodes by adapter shaft (1) wherein, then assemble in crane boom head square tube.This apparatus structure safety and reliability are low, and install complicated, the requirement on machining accuracy of adapter shaft (1) is high simultaneously, and manufacturing cost is high, manufacturing process more complicated and trouble; In addition, adopt the structure of adapter shaft (1), in installation process, between two otic placodes axle being arranged on welding, need adopt small―gap suture to coordinate with bearing pin and hole simultaneously, install difficulty increase.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of tower crane arm head anti-twisting equipment, and structure is simple, production and processing is convenient, cost-saving, does not need to process the higher hole of otic placode dimension precision requirement, save production process, improve work efficiency, safety and firmness.
To achieve these goals, a kind of tower crane arm head anti-twisting equipment that the utility model adopts, comprise for the wedge joint of connecting steel wire ropes, the ear seat be connected with wedge joint, the two pieces of otic placodes be welded in arm head square tube, also comprise the bearing seat be fixed on two pieces of otic placodes;
Described bearing seat is connected with ear seat by bolt, between bolt and bearing seat, axle sleeve is installed, described bearing seat front end is provided with bearing, fixing pressing plate is installed outside bearing, bolt outside pressing plate is equipped with the nut for fastener shaft bearing and bearing, the opposite side of nut is provided with the pin II for stop nut.
Further, wedge joint is connected with ear seat by bearing pin, bearing pin is provided with the pin I for fixed pin shaft.
Further, on bearing pin, one end of mount pin I is provided with packing ring near the position of ear seat.
Preferably, bearing seat is welded on two pieces of otic placodes.
Compared with the existing detachable anti-twisting equipment installed by adapter shaft, bearing seat is directly welded on two pieces of otic placodes of arm head square tube by the utility model, and this device has the following advantages:
1. structure is simple, and production and processing is convenient, cost-saving, is fixedly connected with, does not need the hole that accurate to dimension requirement is higher on otic placode, save the work in production process, improve the efficiency of production and processing owing to adopting.
2. installation, convenient disassembly.Installation, unloading process are avoided being loaded by adapter shaft in two otic placodes, save operation.
3. apparatus structure is stablized, and safety performance is high.
