Light-duty lifting mode boom crane; Comprise in joint under hydraulic chain lifting device, the crane arm, leading sheave, rack-and-gear lifting device, the crane arm that joint, suspension hook, cantilever hang on joint, the crane arm, manual chain block, electrical source of power case, winch, Pyatyi Working pedal, job platform, pad pin screw rod; Said hydraulic chain lifting device is positioned at joint right-hand end under the crane arm; Said crane arm joint left end down is equipped with leading sheave, saves on joint, the crane arm in joint, the crane arm under the crane arm to be connected in turn, and the joint middle part is equipped with the rack-and-gear lifting device in the said crane arm; Joint is connected with cantilever and hangs on the said crane arm; The top that said cantilever hangs is equipped with suspension hook, and said job platform and crane arm support through the Pyatyi Working pedal between the joint down, and said job platform right-hand end is equipped with pad pin screw rod; Said winch is installed on the job platform; And be connected with leading sheave through steel rope, the electrical source of power case is installed on the said job platform, said manual chain block is installed in and saves the bottom in the crane arm.
Beneficial effect
The transportation of the utility model loading is quick, mobile flexible, lifting is safe and efficient; The utility model aim at substation the part primary equipment technological transformation and installation and design; Its loop wheel machine considers that a lot of zones of substation are unfavorable for that large-scale crane carries out field operation; This type hoisting crane volume is little, is convenient to move and pass through equipment, can carry out the replacing and the installation of primary equipment below 1 ton.Be specially adapted to not have installation and the lightning arrester of 220kV and following voltage class at the GIS station of driving, the installation of disconnector.The utility model jenny is to correct position; The adjusting pad pin is to proper height; Guarantee platform level (can place sleeper in the pad underfooting during unfairness of ground), under the telescopic boom contraction state, hold up crane arm, utilize gear to go up and down to regulate to go up the joint height; Through in the regulation of hydraulic system, on save to proper height, and telescopic boom is fixed; Slowly hoisting heavy utilizes chain and tackle block to regulate cantilever and hangs angle, thereby realize accurate centering to correct position.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; The structural representation of light-duty lifting mode boom crane; Light-duty lifting mode boom crane; Comprise that hydraulic chain lifting device 1, crane arm save 5 down in joint 2, leading sheave 3, rack-and-gear lifting device 4, the crane arm, save 6 on the crane arm, suspension hook 7, cantilever hang 8, manual chain block 9, electrical source of power case 10, winch 11, Pyatyi Working pedal 12, job platform 13, pad pin screw rod 14, said hydraulic chain lifting device 1 is positioned at joint 2 right-hand end crane arm under, said crane arm saves 2 left end down leading sheave 3 is installed; Crane arm saves down 5 in joint 2, the crane arm, joint 6 is connected in turn on the crane arm; Joint 5 middle parts are equipped with rack-and-gear lifting device 4 in the said crane arm, and joint 6 is connected with cantilever and hangs 8 on the said crane arm, and said cantilever hangs 8 top suspension hook 7 is installed; Said job platform 13 and crane arm support through Pyatyi Working pedal 12 between the joint 2 down; Said job platform 13 right-hand end are equipped with pad pin screw rod 14, and said winch 11 is installed on the job platform 13, and is connected with leading sheave 3 through steel rope; On the said job platform 13 electrical source of power case 10 is installed, said manual chain block 9 is installed in joint 5 bottoms in the crane arm.
Crane arm goes up and down to lean on rack-and-gear lifting device 4 between saving 5 in joint 6 and the crane arm on the crane arm; Telescopic boom went up and down to lean on hydraulic chain lifting device 1 between joint 5 and crane arm saved 2 down in the crane arm; The crane arm that the other side's steel is done adopts U type pierced process, alleviates its weight, is convenient to; The inverted design of crane arm (under save correct position design rotating shaft), after crane arm fell, effectively reduce the space that occupies; Whole crane arm divide under the crane arm save 5 in joint 2, the crane arm, joint 6 three joint designs on the crane arm, can effectively reduce the hoisting crane transportation, enter the space that the storehouse occupies according to actual its height of sling height adjustment during use;
