Description
Technical field
The present invention relates to a kind of loading trolley, more particularly to a kind of Novel lightweight loading trolley belongs to derrick crane
Technical field.
Background technology
In existing tower crane structure, mostly using loading trolley as shown in Figure 1, it includes assembly pulley 1 and for propping up
The support of assembly pulley 1 is supportted, the support includes side plate 2, first crossbeam 3 and second cross beam 4, and first crossbeam 3 is arranged on assembly pulley 1
Side, side plate 2 is arranged on the two ends of first crossbeam 3, and second cross beam 4 is located at the upper end of side plate 2, and second cross beam 4 parallel to the
One crossbeam 3.Certainly the heavy duty of the loading trolley of middle or small tonnage tower crane is fairly obvious for the influence of the effective lifting capacity of tower crane, in order to
Cost of manufacture is reduced, therefore is widely used.
On the less flat arm derrick crane of lifting tonnage, loading trolley bears larger load.Now, in order to help
Load-carrying, the shaped steel that the general Commonly Used Size of rigidity of dolly is larger is welded.The deadweight of so loading trolley is generally larger.Cause
This, this loading trolley substantially reduces effective lifting capacity of tower crane.
The content of the invention
For the problem that above-mentioned prior art is present, the present invention provides a kind of Novel lightweight loading trolley, and construction is reasonable,
Easy to manufacture, can greatly improve tower crane lifting performance.
To achieve these goals, a kind of Novel lightweight loading trolley that the present invention is used, including assembly pulley, be arranged on
The first crossbeam of assembly pulley side, also including be installed on first crossbeam side and can on flat arm luffing walking truss structure；
The truss structure includes vertical beam, the first cant beam and the second cant beam, and first cant beam and the second cant beam are symmetrically solid
Due to the top of vertical beam；
The vertical beam is perpendicularly fixed at the center of first crossbeam.
Used as improvement, described the first cant beam, the length of the second cant beam are all higher than the length of vertical beam.
As improvement, first cant beam, the second cant beam structure it is identical.
Used as improvement, the angle between the first described cant beam and the second cant beam is 120 °, between first cant beam and vertical beam,
Angle between the second cant beam and vertical beam is also 120 °.
Used as improvement, the end of first cant beam and the second cant beam is respectively provided with the steamboat walked on flat arm
Group.
Used as improvement, the vertical beam is welded on first crossbeam.
Used as improvement, first cant beam and the second cant beam are symmetrically welded at the top of vertical beam.
Compared with prior art, lightweight loading trolley of the invention has rational in infrastructure, safe and reliable, convenient and practical
Feature, specially：
1) new in structure.For Novel lightweight loading trolley, it is thus only necessary in the design phase by loading trolley
Support framework carries out necessary new design；Part carries out the reinforcement of rigidity, intensity, and increasing necessary structural element can meet
It is required that.
2) manufacturing process is slightly adjusted.According to the structure type of Novel lightweight so that lightweight loading trolley is in stress
Transition, local strengthening can be realized easily so that manufacture processing is easily achieved.
3) using easy to operate.According to the mounting characteristic of loading trolley, it is the installation of loading trolley, safeguards and other behaviour
Make to provide more convenient operating procedure.
4) rationally, processing and manufacturing cost reduction, using easy to operate, creates this hair for tower crane performance boost, structure type
Bright remarkable advantage.

Fig. 1 is the structural representation of existing loading trolley；
Fig. 2 is structural representation of the invention；
In figure：1st, assembly pulley, 2, side plate, 3, first crossbeam, 4, second cross beam, 5, vertical beam, the 6, first cant beam, 7, second is oblique
Beam.
Specific embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, below by drawings and Examples, to this
Invention is further elaborated.However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention,
The scope being not intended to limit the invention.
Unless otherwise defined, all of technical term used herein and scientific terminology are led with technology of the invention is belonged to
The implication that the technical staff in domain is generally understood that is identical, and the term for being used in the description of the invention herein is intended merely to retouch
State the purpose of specific embodiment, it is not intended that in the limitation present invention.
As shown in Fig. 2 a kind of Novel lightweight loading trolley, including assembly pulley 1, it is arranged on the first of the side of assembly pulley 1
Crossbeam 3, also including be installed on the side of first crossbeam 3 and can on flat arm luffing walking truss structure；
The truss structure includes vertical beam 5, the first cant beam 6 and the second cant beam 7, first cant beam, 6 and second cant beam 7 pairs
Title is fixed on the top of vertical beam 5；The vertical beam 5 is perpendicularly fixed at the center of first crossbeam 3.By vertical beam 5, the first cant beam 6
The truss structure constituted with the second cant beam 7, effectively reduces the deadweight of loading trolley, lifts effective elevating capacity of tower crane.
Used as the improvement of embodiment, described the first cant beam 6, the length of the second cant beam 7 are all higher than the length of vertical beam 5.
As the improvement of embodiment, first cant beam 6, the second cant beam 7 structure it is identical, easy to process, manufacturing cost
It is low.
Used as the improvement of embodiment, the angle between the first described cant beam 6 and the second cant beam 7 is 120 °, and described first is oblique
Angle between beam 6 and vertical beam 5, between the second cant beam 7 and vertical beam 5 is also 120 °.Reasonable in design, overall steadiness is high.
Used as the improvement of embodiment, the end of the cant beam 7 of first cant beam 6 and second is respectively provided with up in flat arm
The steamboat group walked, makes the loading trolley to be walked on flat arm, plays luffing effect.
Used as the improvement of embodiment, the vertical beam 5 is welded on first crossbeam 3；Further, the He of the first cant beam 6
Second cant beam 7 is symmetrically welded at the top of vertical beam 5.Using welding, overall structure steadiness is high, using safer.
The characteristics of lightweight loading trolley of the invention has rational in infrastructure, safe and reliable, convenient and practical, specially：
1) new in structure.For Novel lightweight loading trolley, it is thus only necessary in the design phase by loading trolley
Support framework carries out necessary new design；Part carries out the reinforcement of rigidity, intensity, and increasing necessary structural element can meet
