Description
Technical field
The utility model relates to a kind of crane arm pull bar welding rollover stand frock, belongs to technical field of engineering machinery.
Background technology
Tower machine, i.e. " derrick crane ", claims again by " tower crane ", is a kind of crane gear for construction.In general tower machine comes to be divided into by functions: basis, tower body, jacking, turn round, hoist, the part such as counter-jib, crane arm, trolley, tower top, drivers' cab, luffing, crane arm is the part of the force of lifting heavy.First the production process of crane arm pull bar is by artificial assembled its parts relative position that is welded and fixed at present, and then its integral body is carried out to welding form, because the effect of downhand welding in welding process is best, therefore need to overturn and be beneficial to workman and carry out downhand welding operation crane arm pull bar, but because crane arm pull bar volume is larger, overturn very inconvenient, labor strength is high, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of crane arm pull bar welding rollover stand frock is provided, and it can overturn to crane arm pull bar easily, is conducive to workman and carries out downhand welding operation, the labour intensity that greatly reduces workman, has improved production efficiency.
The purpose of this utility model is achieved in that a kind of crane arm pull bar welding rollover stand frock, it comprises upset stand, the right both sides of described upset stand top left are provided with rolling bearing units, on the rolling bearing units of the described left and right sides, be all coated with axle, on the axle of the described left and right sides, be provided with fixed head, between the fixed head of the described left and right sides, by nut, be connected with gimbal axis, the shaft end in described left side is provided with left positioning seat, the shaft end on described right side is provided with right positioning seat, described left positioning seat is vertically coated with the first tightening pin, described right positioning seat is vertically coated with the second tightening pin.
On described right positioning seat, be provided with alignment pin, described alignment pin is arranged at the second tightening pin left side.
Compared with prior art, the utlity model has following beneficial effect:
A kind of crane arm pull bar welding of the utility model rollover stand frock, it can overturn to crane arm pull bar easily, is conducive to workman and carries out downhand welding operation, greatly reduces workman's labour intensity, has improved production efficiency.
