Abstract

The utility model relates to a hydraulic total drive rapid telescope cantilever crane fir self-propelled power station, which comprises a fixed support arranged on the machine of power station, a rotating supporting seat is arranged on the fixed support, a fluid drive capstan is fixed on the rotating supporting seat, the cable rope of a hydraulic driven capstan is connected with a hook on front end of the telescope cantilever crane through a fixed pulley and a pulley block, the top of the rotating supporting seat is articulated with the rear end of a telescoping boom, the boom comprises a fixed arm and an internal telescope movable arm, the fixed arm is provided with a telescope hydraulic cylinder, the piston rod end of the telescope hydraulic cylinder is provided with a rotating gear around self axis, the upper part of the gear is meshed with the rack arranged on movable arm, which lower part is meshed with the rack of the fixed arm to adjust the telescope of the boom. Thus, the utility model can expand the working range of the boom, improve working safety, facilitate the general device of power station and effectively diminish the working impact load.

Description

Self-propelling hydraulic whole-drive quick-stretching jib crane for power plant

Technical field:

The utility model relates to the mobile power station technical field, relates in particular to self-propelled mobile power station and drives the quick-expansion cantilever entirely with hydraulic pressure and hang.

Background technology:

It is to walk one of the important accessory device in power station certainly that cantilever hangs, and at present, some self-propelled mobile power station is unkitted cantilever and hangs, though some has cantilever to hang, adopt mechanical type fixed length arm mechanically driver type, the fixed length arm makes and to move that to hang thing dangerous, Mechanical Driven makes the general layout difficulty, and the operation impact load is big.

The utility model content:

In order to solve the problem of above-mentioned existence, the utility model provides a kind of self-propelled mobile power station to drive the quick-expansion cantilever entirely with hydraulic pressure and hangs, and this cantilever hangs and can not only more safely move the lift heavy thing, and is convenient to the general layout in power station, and has relaxed impact effectively.

The technical scheme that the utility model adopted is: a kind of self-propelling hydraulic whole-drive quick-stretching jib crane for power plant, should flexible cantilever bull ladle draw together the fixed bearing on the body that is used to be installed in the power station, be rotatably equipped with rotatable bearing on the fixed bearing, be fixed with the hydraulic-driven capstan winch on the rotatable bearing, cable on the hydraulic-driven capstan winch is connected with the suspension hook that flexible cantilever hangs front end with assembly pulley by fixed pulley, the top of rotatable bearing and the rear end hinge of telescoping boom, arm is made of the swing arm of deciding arm and inner flexible assembling thereof, telescopic hydraulic cylinder is installed in deciding arm, the piston rod end of telescopic hydraulic cylinder is installed one can be around self rotational gear, the top of gear and the tooth bar engagement that is installed on the swing arm, mesh with being installed in the tooth bar of deciding on the arm its underpart, to regulate the flexible of arm.

In the angle of deciding between arm and the rotatable bearing hydraulic ram is installed, an end and the rotatable bearing of hydraulic ram are hinged, and the other end is with decide arm hinged, with the pitching of adjusting arm.

The utility model is simple in structure, and operating range is big, and motion steadily, and is safe and reliable.Adopt rapid telescopic arm to replace the fixed length arm, both enlarged the operating range of arm, improved the safety of work again.Change Mechanical Driven into hydraulic-driven, made things convenient for the general layout in power station like this.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

As shown in the figure, the flexible cantilever bull ladle of self-propelling hydraulic whole-drive quick-stretching jib crane for power plant of the present utility model is drawn together the fixed bearing 1 on the body that is used to be installed in the power station, be rotatably equipped with rotatable bearing 3 on the fixed bearing 1, be fixed with hydraulic-driven capstan winch 2 on the rotatable bearing 3, cable on the hydraulic-driven capstan winch 2 is connected with the suspension hook that flexible cantilever hangs front end with assembly pulley by fixed pulley, the top of rotatable bearing 3 and the rear end hinge of telescoping boom, arm is made of the swing arm 10 of deciding arm 9 and inner flexible assembling thereof, telescopic hydraulic cylinder 5 is installed in deciding arm 9, the piston rod end of telescopic hydraulic cylinder 5 is installed one can be around self rotational gear 6, the top of gear 6 and tooth bar 7 engagements that are installed on the swing arm 10, mesh with being installed in the tooth bar of deciding on the arm 9 (8) its underpart, to regulate the flexible of arm.In the angle of deciding between arm 9 and the rotatable bearing 3 hydraulic ram 4 is installed, an end and the rotatable bearing 3 of hydraulic ram 4 are hinged, and the other end is with decide arm 9 hinged, with the pitching of adjusting arm.The stroke of swing arm 10 is twices of the stroke of telescopic hydraulic cylinder 5, has reached the purpose of quick-expansion.
