Cranemobile to walk driving be automobile, the vehicle body of automobile is longer, in narrower occasion operation, moves very inconvenient;
2. the actuating device that drives the telescopic crane arm fore and aft motion of more piece is a fluid pressure drive device, and the cost of fluid pressure drive device is higher.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose a kind of a kind of walking type crane---trac. crane very convenient, that cost is lower that moves.
The utility model is realized with the following method.
The trac. crane has four-wheeled tractor, crane with the scalable crane arm of more piece is arranged on the chassis frame at four-wheeled tractor rear portion, be connected with steel wire rope winch on the power take-off shaft of trac., the steel rope of winch is connected with load hook through crane arm, have on the chassis frame of trac. and ground between the hydraulic pressure hold-down arm, crane has the crane base, the pivoting support that useful rotary hydraulic motor drives on the crane base, column is arranged on the pivoting support, the column upper end is hinged with square tube shape fixed arm, be connected with the diagonal ligament hydraulic actuating cylinder between column and the fixed arm, be with the square tube shape second joint arm in the square tube shape fixed arm, be with square tube shape the 3rd joint arm in the second joint arm, be connected with sprocket wheel chain retractable driving device between the fixed arm and the second joint arm, be connected with shackle line between the second joint arm and the 3rd joint arm, the sprocket wheel chain retractable driving device that is connected with between the fixed arm and the second joint arm has square tube shape housing, there is sprocket wheel at two ends in the square tube shape housing, be connected with chain between the sprocket wheel at two ends, there is flexible HM Hydraulic Motor the inner end of square tube shape housing, flexible HM Hydraulic Motor links to each other by the sprocket wheel of the inner end in driving device and the square tube shape housing, the inner end of square tube shape housing is hinged on the inner end of fixed arm, it is to connect joint that one joint is arranged on the chain, and connection joint location is connected on the inwall of the second joint arm inner end.
During use, prop the car beam of trac. and the hydraulic pressure hold-down arm between ground, with the rotary hydraulic motor of pivoting support and the diagonal ligament hydraulic actuating cylinder between column and the fixed arm crane arm is adjusted to the hoisting operation position, during as needs elongation crane arm, start flexible HM Hydraulic Motor, drive chain movement, because it is to connect joint that a joint is arranged on the chain, connecting joint locatees on the inner end inwall that is connected in the second joint arm, can drive the second joint arm stretches out in fixed arm, again because the second joint arm is connected with shackle line with the 3rd joint between the arm, the second joint arm can drive the 3rd joint arm and save in the arm from second and stretch out when stretching out in the fixed arm.After hoisting operation is finished, oppositely start flexible HM Hydraulic Motor, in the 3rd joint arm indentation second joint arm that stretches out, simultaneously in the second joint arm indentation fixed arm.
The utility model is compared with the cranemobile in the prior art, because of the present utility model to walk driving be trac., the vehicle body of trac. is shorter, in narrower occasion operation, moves easily; The actuating device that drives the telescopic crane arm fore and aft motion of more piece is a sprocket wheel chain retractable driving device, compares with fluid pressure drive device, and cost is lower.
Below in conjunction with accompanying drawing, the utility model is further described.
