Abstract

The utility model discloses a crane cab pivot arm structure, resolving the crane cab arrangement problem, including a main platform positioned on the crane to support the cab; the main platform includes a support plate and a fixed base plate; a positioning holes is arranged on the support plate, the main platform also includes a swinging boom, one end of the swinging boom is connected with the bottom of the support plate of the main platform via a swinging axis pin, the cab is arranged on the main platform. A swinging support is arranged on the fixed base plate of the main platform. The swinging axis pin runs through the positioning hole on the main platform support plate and is inserted on the swinging boom. When working, take off the positioning axis pin, the cab circumrotates along the axis pin, the cab can be moved to the working position as required or eliminates the influence of the width caused by the cab, the utility model is simple and of low cost, which is convenient for disassembly, the operation and adjustment is simple, the structure is reliable.

Description

A kind of hoisting box swing boom configuration

Technical field

The utility model relates to the crane facility field, particularly hoisting box's swing boom configuration.

Background technology

Goliath is bulky, operator's compartment is positioned at the side of main crane arm, so the complete machine width exceeds the traffic condition restriction, super wide during the crane mainframe transportation, goliath control simultaneously is complicated, intricate from all kinds of cables, hydraulic oil pipe that operator's compartment is drawn, exposed dangerous outside also not attractive in appearance.

Guarantee the solution that a large amount of pipelines pass through in the time of for crane mainframe transporting over-wide problem, at present beyond example still.

Summary of the invention

The purpose of this utility model provides a kind of hoisting box swing boom configuration, solves goliath main frame transporting over-wide problem.

For achieving the above object, the technical solution of the utility model is:

A kind of hoisting box swing boom configuration is installed on hoisting crane master platform, to support operator's compartment; Described main platform comprises a stay bearing plate and fixed base plate; Have knock hole on this stay bearing plate; Also comprise, revoliving arm, the one end is movably connected under the hoisting crane master flat-bed stay bearing plate by the revolution bearing pin, and the operator's compartment setting is thereon; Revolution is supported, and is arranged on the main flat-bed fixed base plate, and revoliving arm is set up in this revolution and supports; Alignment pin is passed the knock hole on the described main platform stay bearing plate, is inserted on the revoliving arm.

Described revoliving arm is a tubular structure.

Again, also comprise copper sheathing, this copper sheathing is sheathed on the bearing pin, between bearing pin and the revoliving arm, and the friction drag when reducing to rotate makes mechanism's rotation freely.

Described revoliving arm extends to form the platform of a placement operator's compartment to a lateral buckling.

Cab anchorage makes operator's compartment have two kinds of running conditions: mode of operation and travelling position in rotatable revoliving arm.Simultaneously the operator's compartment revoliving arm is made tubular structure, make pipeline can be subjected to the protection of this tubular structure.

During work, pull up alignment pin, operator's compartment can be around the center of gyration rotation of revolution bearing pin and revolution support, when the needs operator's compartment is in running order, operator's compartment is gone to control position and can normal operation with alignment pin location, this moment, main frame added about 4.4 meters of operator's compartment overall width, when the needs operator's compartment is in travelling position, operator's compartment is gone to transporting position and can normal transport with alignment pin location, this moment, main frame added about 3.3 meters of operator's compartment overall width, had eliminated the influence of operator's compartment to complete machine transportation width.

Advantage of the present utility model is:

(1) the utility model is simple in structure, and realization and cost are lower easily;

(2) motion parts is that bearing pin connects easy accessibility;

(3) adjustment, simple to operate, reliability is higher.

Description of drawings

Fig. 1 is the utility model scheme drawing in working order;

Fig. 2 is the A portion enlarged diagram of Fig. 1;

Fig. 3 is the utility model scheme drawing in working order;

Fig. 4 is the scheme drawing of the utility model at travelling position.

The specific embodiment

Further specify structure of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 2, hoisting box of the present utility model swing boom configuration is installed on hoisting crane master platform 6, to support operator's compartment 7; Described main platform 6 comprises a stay bearing plate 61 and fixed base plate 62; Have knock hole 611 on this stay bearing plate 61;

Revoliving arm 1, it is a tubular structure, and the one end is movably connected on hoisting crane master flat-bed stay bearing plate 61 times by revolution bearing pin 2, and operator's compartment 7 is provided with thereon; And described revoliving arm 1 extends to form the platform 11 of a placement operator's compartment 7 to a lateral buckling;

Revolution supports 3, is arranged on the fixed base plate 62 of main platform 6, and revoliving arm 1 is set up in this revolution and supports 3; Alignment pin 4 is passed the knock hole 611 on described main platform 6 stay bearing plates 61, is inserted on the revoliving arm 1; Copper sheathing 5 is sheathed on the revolution bearing pin 2, turns round between bearing pin 2 and the revoliving arm 1.

In structure of the present utility model, operator's compartment 7 is a main consuming body, and the effect of revoliving arm 1 is to connect main platform 6 and operator's compartment 7, and operator's compartment 7 is the axle center of rotation with revolution bearing pin 2, and alignment pin 4 is used for limiting the final position of operator's compartment under two states.

Referring to Fig. 3, Fig. 4, it is depicted as the utility model working state schematic representation;

Shown in Figure 3, during its utility model mode of operation operator's compartment 7 is rotated to the side of main platform 6, guarantee need of work.

Fig. 4 is the scheme drawing of the utility model at travelling position, during travelling position operator's compartment 7 is rotated to the front of main platform 6, satisfies the traffic condition needs.
