Abstract

The utility model provides a revolving table structure for folding-arm type lorry loading cranes. The utility model is structurally characterized in that two upright posts are fixed on a revolving bottom plate, and the upper parts of the upright posts are fixed with cross beams; the upright posts, together with upright plates and closing plates, form a box-type structure, and the cross beams are hollow structures formed by back closing plates and groove-shaped plates. The cross beams, the revolving bottom plate and the right and left upright posts are welded into integration to form a portal frame structure, and a crane arm of the folding-arm type lorry loading crane can be folded into a portal frame. Therefore, the utility model has the characteristics of high strength, light weight and large effectively utilized space and can satisfy the requirements of the installation of folding-arm type lorry loading cranes, the fold of the crane arm and a small revolving radius when the crane arm lies in a folding state.

Description

Folding-jib lorry-mounted crane turntable structure
Affiliated technical field
The utility model relates to the car hosit turntable structure, especially folding-jib lorry-mounted crane turntable structure.
Background technology
The present car hosit especially turntable of lorry-mounted crane mostly is single upright post type.The turntable of this structure, crane arm are positioned at the turntable side, and the crane arm down hinge is in the cantilever beam state, and hinge is stressed greatly, complete machine stability is poor, lifting performance is low.Other type turntable structure is also arranged, but because of complex structure can not the folding crane arm.
The utility model content
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of crane arm that makes mid-and the turntable structure of its folding shallow storage space arranged.
The method that realizes the utility model purpose is: on turntable, the column bottom is fixed on the revolution base plate, the folding arm hinge-point is arranged at the column top, be equipped with axle sleeve in the hinge-point, it is characterized in that: fixing column is left-right symmetric gapped two root posts that are parallel to each other on the revolution base plate, column upper fixed crossbeam forms a pair of column portal framed structure.
Every root post forms an osed top box type construction by low wide and up narrow at right angles leg-of-mutton two riser and shroudings parallel to each other.
The riser lower abdomen is provided with the built-in space of erecting crane revolution cabinet.
The column upper cross-beam is made of a spill frid and box type construction beam and the pipe reinforced rib that the back shrouding constitutes.
The beneficial effects of the utility model are: 1, make the stressed single supported beam state that is in of crane arm down hinge, improved down hinge and turntable stress performance.2, the stability of complete machine and the lifting performance of complete machine have been improved.3, be in the turntable door opening after making the crane arm folding.4, the revolution cabinet is built in the turntable, has made full use of the design space, satisfied the requirement of small swing radius when crane arm is in folding state, enlarged the Applicable scope of lorry-mounted crane.
Description of drawings
Embodiment is further described the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structure side schematic view of the present utility model;
Fig. 2 is a structure forward scheme drawing of the present utility model.
Among the figure, 1, the back shrouding, 2, axle sleeve, 3, riser, 4, riser, 5, shrouding, 6, shrouding, 7, frid, 8, pipe, 9, column, 10, the hoop plate, 11, the revolution base plate, 12, the bottom reinforced rib, 13, built-in space.
The specific embodiment
As shown in Figure 2, the column of fixing on revolution base plate 11 9 is gapped two root posts for left-right symmetric is parallel to each other, and the upper fixed crossbeam of column 9 forms a pair of column portal framed structure.Every root post 9 is welded into box type construction by inboard riser 3 and outer cant board 4 with shrouding 5, shrouding 6, be parallel to each other between riser 3 and the riser 4, the low wide and up narrow rectangular triangle of the shape of riser 3,4, as shown in Figure 1, left and right pillar 9 is fixing with 11 welding of revolution base plate by location dimension.Above column 9, back shrouding 1 welds with left and right pillar 9 with the two ends of the box type construction beam that spill frid 7 is constituted, and the two ends of pipe 8 are welded in the column 9.The folding arm hinge knock hole prtreatment at column 9 tops is welded on axle sleeve 2 in the hole, will weld axon cover 2 again and carry out fine limit work, guarantees dimensional accuracy, symmetry, the right alignment of axle sleeve 2.At the bottom of column 9 welding reinforced rib 12, to reinforce column 9 and to turn round being connected of base plate 11.Open a long slot bore at the lower abdomen of riser 4, seal reinforcement, form a built-in space 13, be used for erecting crane revolution cabinet with hoop plate 10.

Claims (4)

1, a kind of folding-jib lorry-mounted crane turntable structure, comprise revolution base plate and column, the column bottom is fixed on the revolution base plate, the column upper end has the folding arm hinge-point, be equipped with axle sleeve in the hinge-point, it is characterized in that: fixing column is left-right symmetric gapped two root posts that are parallel to each other on the revolution base plate, and column upper fixed crossbeam forms a pair of column portal framed structure.
