Description

Fast frame rubber tired crane

Technical field

The utility model relates to a kind of hoisting crane, relates in particular to a kind of fast frame rubber tired crane.

Background technology

Existing tower crane generally is made up of jib, body of the tower, cat head, hoisting mechanism, erecting device, swing type mechanism, luffing mechanism and traveling gear, must water underpin as required before installing, and erection mode generally is that secondary property is set up; Both earlier upright body of the tower; Treat after body of the tower stands directly jib to be installed again, car hosit of whole erection process need, a 5-6 installer, the time that spends one day just can be set up completion; Its installation, set up, transportation is complicated, time-consuming.

The utility model content

The utility model technical matters to be solved is: a kind of fast frame rubber tired crane is provided; Its self-powered traveling gear, whole erection process need not other hoisting crane and assist, and only need 2 people to accomplish; And need not aloft work, can in 30 minutes, accomplish and set up.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is:

A kind of fast frame rubber tired crane; Comprise chassis 1, turn table 2, lift winch 3, hoisting winding 5, four connection-rod support 7, folding arm device 8, crane arm front end 9, luffing steel rope expansion bracket 10, latching device 11, crane arm rear end 12, interior body of the tower 13, outer body of the tower 14; Chassis 1 and turn table 2 bolt togethers; Lift winch 3, hoisting winding 5 are fixed by bolts on the turn table 2, and luffing steel rope expansion bracket 10 is through bolt crane arm front end 9, and latching device 11 is through bolt crane arm rear end 12; Crane arm front end 9 is connected by folding arm device 8 with crane arm rear end 12; Crane arm rear end 12 and interior body of the tower 13 are connected through bearing pin, and slide block sliding extension each other is housed between interior body of the tower 13 and the outer body of the tower 14, and outer body of the tower 14 is connected with turn table 2 through four connection-rod support 7.

The principle of work of the utility model:

Erection process: after hoisting crane arrives control position, at first, start lift winch 3 four supporting leg adjustment of chassis 1 usefulness level; Steel rope is walked around fixed pulley group 4, running block 6, under the support of four connection-rod support 7, erects body of the tower; After body of the tower is vertical, be fixed together outer body of the tower 14 with turn table 2 with latch, extract latch then; Continue to start lift winch 3, after body of the tower 13 rises to control position in making, be fixed together interior body of the tower 13 with outer body of the tower 14 with latch.

In the process that interior body of the tower 13 rises; Crane arm leaves body of the tower simultaneously under the pulling of fixed length drag-line, crane arm front end 9 launches under the effect of folding arm device 8 slowly simultaneously; Crane arm stretches the back that puts in place and is locked the crane arm rear and front end by latching device 11; The telescopic adjustment of luffing steel rope is accomplished by luffing steel rope expansion bracket 10, and the erection process of whole hoisting crane is all accomplished, and hoisting crane begins to get into mode of operation.

Pack up process: hoisting crane pack up process and erection process is opposite, shrink telescopic oil cylinder, the luffing steel rope fluffs; Folding arm device 8 folds crane arm, extracts latch, starts lift winch 3; Interior body of the tower 13 slowly descends, and crane arm closes up with body of the tower gradually simultaneously, after interior body of the tower 13 puts in place; Be fixed together outer body of the tower 14 and interior body of the tower 13 with latch, continue to start lift winch 3, whole body of the tower together with crane arm under the support of four connection-rod support 7; Fell slowly, arrived folded state until level.

The beneficial effect of the utility model is: simple in structure, and install, set up, convenient transportation, increase work efficiency.
