Abstract
The utility model is related to a kind of balance arm of tower-type crane welding toolings.The welding of counter-jib at present is that first assembly is welded again, and for traditional welding due to immovable and rotation, welding process is cumbersome, and turn also wastes time very much.The utility model includes two support bases, rotating turret is set on the support base, motor is set in one fulcrum bearing, the shaft of motor connects drive end file leader, rotating turret is set on the drive end file leader, the rotating turret connects counter-jib by axis pin, and driven spindle and driven end file leader is arranged in another fulcrum bearing.The utility model makes bearing and pivoted frame, and counter-jib is connect with pivoted frame with axis pin, implements welding after installing.Pivoted arm can rotate freely angle within the scope of 360 ° in entire welding process, and operation is flexible.
Description
Technical field
The utility model is related to a kind of balance arm of tower-type crane welding toolings.
Background technology
The welding of counter-jib at present is that first assembly is welded again, and traditional welding is due to immovable and rotation, welding process ratio
Cumbersome, turn also wastes time very much.There is also welding bead angle problems in welding process, it is necessary to driving reverse welding, welding
Both sides mounting hole is not positioned in the process, since welding is shunk after the completion of welding, certain influence can be equipped on counter-jib.
Utility model content
The utility model aims at the problems existing in the prior art, and provides a kind of balance arm of tower-type crane welding toolings, subtract
Few use because of reverse welding to driving can be welded directly in tooling, be removed after the completion of welding, and working efficiency and peace are improved
Quan Xing.
For this purpose, the utility model discloses a kind of balance arm of tower-type crane welding tooling, it is characterised in that including two branch
Seat is supportted, rotating turret is set on the support base, motor is set in a fulcrum bearing, the shaft of motor connects drive end file leader,
Rotating turret is set on the drive end file leader, and the rotating turret connects counter-jib by axis pin, set in another fulcrum bearing
Set driven spindle and driven end file leader.
Hold-down mechanism is arranged in the lower part of the drive end file leader and driven end file leader.
A connection triangle is also set up on the inside of the driven end file leader, the connection triangle is connect with counter-jib.
The utility model makes bearing and pivoted frame, and counter-jib is connect with pivoted frame with axis pin, implements welding after installing.
Pivoted arm can rotate freely angle within the scope of 360 ° in entire welding process, and operation is flexible.The utility model can ensure to balance
Arm size constancy shape facilitates welding, and 360 ° of rotating weldings of energy, production effect is substantially increased while ensureing that size requires
Rate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the vertical view of Fig. 1.
In figure：1, bolt axle 2, locking plate 3, bearing block 4, shaft 5, boring cover 6, transparent cover 7, axle sleeve 8, driven end row
First 9, triangle 10, axis pin 11, pivoted frame 12, boring cover 13, drive end file leader 14, transparent cover 15, spacer 16, bearing are connected
17, shaft 18, speed reducer 19, motor 20, axis pin 21, hold-down mechanism.
Specific implementation mode
Specific be described in detail is made to the utility model below in conjunction with the accompanying drawings.
A kind of balance arm of tower-type crane welding tooling as shown in Figs. 1-2, including two support bases, on a support base
The driven spindle mechanism that setting is made of bearing block 3, driven spindle 4, boring cover 5, transparent cover 6, axle sleeve 7, the driven spindle connect
Driven end file leader 8 is met, pivoted frame is set on driven end file leader, bolt axle 1 and locking plate 2 are set on pivoted frame.It is set on another support base
Set bearing 16, the side setting speed reducer 18 and motor 19 of bearing, setting boring cover 12 in the shaft 17 of speed reducer, transparent cover 14,
Spacer 15, shaft 17 connect drive end file leader 13, and pivoted frame 11 is arranged in 13 inside of drive end file leader, and installation axis pin 20 connects on pivoted frame 11
Connect counter-jib.
Hold-down mechanism 21 is arranged in the lower part of drive end file leader and driven end file leader.One is also set up on the inside of driven end file leader
Triangle 9 is connected, connection triangle upper end is connect by axis pin 10 with counter-jib.
Utility model itself finds landing nipple by counter-jib model, by work piece hoisting, after axis pin connects, uses compacting machine
Structure 21 compresses securely, by driving the motor 19 at end to carry out rotating welding, until all being removed after the completion of welding.Length is different
Arm can use connection triangle joint.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should
It is subject to the protection scope in claims.
