Abstract
The invention provides a crane and a frame. The frame comprises a frame front section and a frame rear section connected with the frame front section, wherein the frame rear section comprises a top wall, a bottom wall opposite to the top wall and two side walls for connecting the top wall with the bottom wall; and the bottom wall is a flat plate structure. Compared with the traditional frame section with polygonal section, the frame rear section according to the invention has a section in the form of rectangular frame. Therefore, the weight of the frame can be relatively reduced so that the frame is beneficial for lightweight development of the crane. The frame rear section comprises a side wall, a top wall and a bottom wall, wherein the side wall, the top wall and the bottom wall are welded together; therefore, compared with the traditional polygonal frame rear section, the weld joints of the frame rear section are reduced to improve the stability of the frame according to the invention. In addition, the bottom wall of the frame rear section is a flat plate structure so that the frame is beneficial for placing a chassis, a transmission system and other elements and the interference between each element and the bottom wall can be prevented.
Description
Technical field
The invention belongs to the hoisting crane technical field, particularly a kind of hoisting crane and vehicle frame thereof.
Background technology
The load working condition of hoisting crane hoisting operation is complicated.During lifting, the lift heavy and the deadweight of getting on the bus be through the swing bearing seat ring in the middle of the vehicle frame back segment, on vehicle frame, and then passes to Convenient table as loading, passes to movable leg again, is delivered to the road surface at last.As far as vehicle frame, the heavily stressed operating mode of generation has two kinds: fully loaded positive side and fully loaded 45 ° of direction hoisting heavies.The former makes vehicle frame bear maximum twist moment, and the latter makes vehicle frame bear twist moment and moment of deflection that equivalent lift heavy moment causes, and causes maximum outrigger reaction.Therefore, require vehicle frame that enough strength and stiffness must be arranged, resistance to torsion and flexing resistance preferably, under situation about meeting the demands, vehicle frame weight is little simultaneously.
The cross section of existing crane frame is a polygonized structure, and it is welded by some steel plates.The vehicle frame weld seam of this kind structure is more, and resistance to bending is relatively poor.In addition, the bottom of frame shape of this kind structure is comparatively complicated, and the feasible comparatively inconvenience of layout that is installed on other elements such as chassis of bottom of frame is arranged efficiency of operation thereby reduced the chassis.In addition, hoisting crane trends towards the lightness development, and the crane frame of polygonized structure is unfavorable for the lightness of hoisting crane.
Therefore, design and a kind ofly be convenient to the arrangements of elements operation, have the less vehicle frame of higher stability and weight and use the hoisting crane of this vehicle frame, become the problem of needing solution badly.
Summary of the invention
In order to overcome the above-mentioned defective and the deficiency of prior art; The object of the present invention is to provide a kind of vehicle frame; It comprises that the vehicle frame leading portion reaches and this vehicle frame leading portion bonded assembly vehicle frame back segment; This vehicle frame back segment comprises roof, the diapire relative with this roof and is connected two sidewalls of this roof, diapire that this diapire is a slab construction.
Preferably, the cross section of this vehicle frame back segment is a rectangle.
Preferably, this vehicle frame back segment also comprises two strut mounts, and this strut mount is fixed on this diapire.
Preferably, be fixed with support on this strut mount.
Preferably, this vehicle frame back segment also comprises welded plate, and this welded plate is fixed on this strut mount.
Preferably, this vehicle frame back segment also comprises front leg strut and rear support leg, and this front leg strut is articulated in the front end of this vehicle frame back segment, and this rear support leg is fixed on the rear end of this vehicle frame back segment.
Preferably, this front leg strut comprises swing leg and movable supporting legs, and an end of this swing leg is articulated in the front end of this vehicle frame back segment, and this movable supporting legs telescopically is located in this swing leg; This rear support leg comprises fixed supporting leg case and telescopic outrigger, and this fixed supporting leg case is fixed on the rear end of this vehicle frame back segment, and this telescopic outrigger telescopically is connected in this fixed supporting leg case.
The present invention also provides a kind of hoisting crane of using above-mentioned vehicle frame.
Be polygonal vehicle frame back segment with respect to existing cross section, the cross section of this vehicle frame back segment provided by the present invention is the rectangle framework, and therefore, the weight of this vehicle frame can reduce relatively, helps the lightness development of hoisting crane.This vehicle frame back segment comprises sidewall, roof and the diapire that is welded in together, and therefore compared to existing polygonal vehicle frame back segment, the weld seam of vehicle frame back segment of the present invention reduces, thereby has improved the stability of this vehicle frame.In addition, the diapire of this vehicle frame back segment is a slab construction, therefore helps the laying of elements such as chassis, driving system, can prevent to interfere between each element and the diapire.
Description of drawings
The structural representation of the crane frame that provides for preferred embodiment of the present invention shown in Figure 1.
Shown in Figure 2 is cross section structure scheme drawing along A-A direction among Fig. 1.
The specific embodiment
To combine the Fig. 1 to Fig. 2 in the preferred embodiment of the present invention below, the technical scheme in the embodiment of the invention will be carried out clear, intactly description.
The present invention provides a vehicle frame 100, and it is used for hoisting crane.This vehicle frame 100 comprises vehicle frame leading portion 1 and the vehicle frame back segment 3 that is connected with this vehicle frame leading portion 1.
This vehicle frame leading portion 1 adopts structural I-beam, and it is equipped with hoisting crane walking drive part (figure does not show).
The cross section of this vehicle frame back segment 3 is roughly the rectangle frame body structure, and it is made up of roof (figure does not show), diapire 30 and two sidewalls 31 relative with this roof.Said sidewall 31 is welded in this roof and diapire 30.Wherein, this diapire 30 is a slab construction, but installation chassis, driving system etc. on it.
This vehicle frame back segment 3 comprises first connecting arm 32, front leg strut 33, second connecting arm 34, rear support leg 35, strut mount 36 and welded plate 37.Said connecting arm 32 is fixed on the sidewall 31 of these vehicle frame back segment 3 front ends symmetrically.Said front leg strut 33 comprises swing leg 331 and movable supporting legs 333.One end of said swing leg 331 is articulated in the end of cooresponding connecting arm 32.Said movable supporting legs 333 telescopicallies are located in this swing leg 331.Said second connecting arm 34 is fixed in the rear end of this vehicle frame back segment 3.Said rear support leg 35 comprises fixed supporting leg case (figure does not show) and telescopic outrigger 353.Said fixed supporting leg case is fixed on the two ends of this second connecting arm 34.Said telescopic outrigger 353 telescopicallies are connected in the said fixed supporting leg case.The quantity of said strut mount 36 is two, and each strut mount 36 is roughly the rectangular strip structure, and it is fixed in the position of these diapire 30 contiguous two sidewalls 31.Said strut mount 36 is fixed with support 361 away from a side of this diapire 30, and said support 361 is used to install the back overarm.This welded plate 37 roughly is an arch configuration, and its two ends are separately fixed on the said strut mount 36.
