At present, to the scheme that the above-mentioned phenomenon of improvement is taked be in the industry: as shown in Figure 1, welding one guiding bent plate 6 around the outer otic placode pin shaft hole of arm joint, during installation, bearing pin being inserted alternate arm along guiding bent plate saves in the pin shaft hole of inside and outside otic placode, again bearing pin is pounded with instruments such as sledgehammers and pass outer otic placode, plug the lock pin on guiding bent plate, prevent bearing pin from moving radially; During dismounting, with instruments such as sledgehammers, bearing pin is pounded out pin shaft hole, plug lock pin to the bearing pin stayed in guiding bent plate, fixed pin shaft, in guiding bent plate, is delivered at random.Although this scheme without the need to connecting arm joint before delivery, but still sledgehammer need be adopted to complete throwing into of bearing pin get, installing/dismounting difficulty, fragile bearing pin and framing member, impact delivery uses.
Summary of the invention
For above-mentioned prior art Problems existing; what the utility model provided a kind of jib for tower crane arm internode wears pin cylinder bracket structure; not only can realize the connection of arm internode, and it is quick to wear dozen bearing pin, simple to operate; reduce the degree-of-difficulty factor of installing; damage to product when also can reduce handling, protection bearing pin and framing member injury-free, reduce production and processing cost; improve the safety of installing, guarantee the use of delivering.
To achieve these goals, the utility model adopt a kind of jib for tower crane arm internode wear pin cylinder bracket structure, comprise bearing pin, wear pin oil cylinder and be fixed on the support around the outer otic placode upper pin hole of arm joint, bearing pin and wear the top that pin oil cylinder is placed on support, and be connected with the external part wearing pin oil cylinder; Bearing pin moves around along with in the flexible otic placode upper pin hole outside of wearing pin oil cylinder.
Preferably, described support is provided with lock pin, during installation, when bearing pin passes outer otic placode, then locks lock pin, prevents moving radially of bearing pin; During dismounting, treat that bearing pin is extracted out in pin shaft hole, plug lock pin and bearing pin is fixed on support.
Preferably, described bearing pin is provided with baffle plate or locating piece.
Preferably, described support is arcuate structure, and wear pin oil cylinder and be placed on support, the end of wearing pin oil cylinder is fixedly connected with support.
Preferably, on the outer otic placode that described support welding saves at arm
Compared with prior art, the utility model, by outside the otic placode of cargo boom joint, designs one and wears pin cylinder bracket, be designed for the lock pin of fixed pin shaft above support; Connect bearing pin can be designed to be convenient to the form with one end tape spool baffle plate wearing pin oil cylinder.When connecting between cargo boom joint, wear pin oil cylinder and along cylinder bracket, bearing pin is pierced in pin shaft hole, lock lock pin; During dismounting, wear pin oil cylinder and bearing pin extracted along support in pin shaft hole, after lock lock pin; Not only achieve the connection of arm internode, and it is quick to wear dozen bearing pin, simple to operate; reduce the degree-of-difficulty factor of installation, the damage to product simultaneously when reducing handling, protection bearing pin and framing member injury-free; reduce production and processing cost, improve the safety of installation, guarantee the use of delivering.
