Description
Technical Field
The utility model belongs to the technical field of large bulk cargo loading and unloading systems and equipment thereof, and particularly relates to a travelling trolley frame suitable for a large reclaimer.
Background
Referring to fig. 1 to 3, in a traveling carriage of a conventional large-scale reclaimer, a frame of the traveling carriage is formed by welding an upper flange 11, a steel pipe 12, an end plate 14, two side webs 15, a steel plate B16 and a lower flange 17 by means of assembly welding, and at the assembled position of the traveling carriage frame and a balance beam and the assembled position of the traveling carriage frame and traveling wheels, in order to reduce extrusion stress and enhance local strength and rigidity, the traveling carriage frame of the conventional large-scale reclaimer is generally formed by adopting a thick steel plate (steel plate a13 and steel plate B16) at the assembled position, welding the thick steel plate on the two side webs 15, then eliminating welding stress and finally integrally machining the material through a numerical control center.
The web 15 assembly part not only bears the vertical load of the whole reclaimer, but also has the vertical bending moment formed by the vertical supporting reaction force of the travelling wheels and the horizontal bending moment formed by the rail biting force of the travelling wheels, so that the composite stress is very complex.
The splice welds of the steel plate 13 and the web 15 and the splice welds of the steel plate 16 and the web 15 are all one type of weld. The butt joint with different thickness is realized, the arc butt joint is realized, the requirements on the skills of a riveter and an electric welder are very high, meanwhile, the filling quantity of the splicing weld joint of the thick steel plate is too large, the deformation of the web plate is too large after the welding is finished, and the secondary correction is finished.
In general, the traditional large-scale reclaimer walking trolley frame is time-consuming and labor-consuming to manufacture, has long manufacturing period and increases potential safety hazard.
Disclosure of utility model
The technical problems to be solved by the application are as follows: how to provide a walking trolley frame suitable for large-scale reclaimer, it can have rational in infrastructure, simple manufacture, economical and practical, safe and reliable's advantage.
The specific scheme is as follows:
The utility model provides a walking platform truck frame suitable for large-scale reclaimer, includes welded fastening's top flange, steel pipe, end board, both sides web and bottom flange, and both sides web is welded fastening stiffening plate A on the side with compensating beam combination assembly department, and both sides web is welded fastening stiffening plate B on the side with walking wheel combination assembly department.
The reinforcing plate A and the reinforcing plate B are two groups, and are respectively distributed on the inner side surface and the outer side surface of the webs at the two sides.
Compared with the prior art, the beneficial effects are that: the utility model discloses a travelling trolley frame suitable for a large-scale reclaimer, which is characterized in that a reinforcing plate is fixed at an assembly position of a web plate, so that the trolley frame has the advantages of reasonable structure, simplicity in manufacture, economy, applicability, safety and reliability.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.
Referring to fig. 4-6, a traveling trolley frame suitable for a large-scale reclaimer comprises a welded upper flange 11, a steel pipe 12, an end plate 14, two side webs 15 and a lower flange 17.
The two side webs 15 are welded and fixed with the reinforcing plate A18 on the side surface of the assembly position of the balance beam, and the two side webs 15 are welded and fixed with the reinforcing plate B19 on the side surface of the assembly position of the balance beam and the walking wheel.
As shown in fig. 5-6, for the sake of firmness, the stiffening plate a18 and the stiffening plate B19 are two groups, which are respectively distributed on the inner and outer sides of the two side webs 15.
The specific working process is as follows:
In the prior art, thickened steel plates are welded at the edges of webs at two sides, and holes are drilled in the thickened steel plates; the size of the two-side webs 15 of the application is equivalent to the sum of the original two-side webs and the thickened steel plate, and the two-side webs 15 are directly drilled, but after the reinforcing plate A18 or the reinforcing plate B19 is arranged in the drilling area, the total thickness of the drilling area (the three-layer thickness of the two-side webs 15 and the two groups of reinforcing plates A18 or B19) is equivalent to the original thickened steel plate, so that the strength of the trolley is satisfied.
The welding is between the side surfaces of the two side webs 15 and the reinforcing plates A18 and B19, and is firmer than the welding seam (the welding seam is in the thickness direction of the two side webs 15) in the prior art, and the operation is more convenient.
The processing method specifically comprises the following steps:
The first step: the upper flange 11, the steel pipe 12, the reinforcing plate 18, the steel plate 14, the two side webs 15, the reinforcing plate 110 and the lower flange 17 are manufactured by blanking according to the drawing size.
And a second step of: the reinforcing plate 18, the reinforcing plate 110 and the two side webs 15 are assembled and welded according to the technical requirements of the drawing according to the two side webs 15 as the standard.
And a third step of: on the construction platform, lofting is carried out according to the design drawing size, the web plates 15 on two sides, the steel pipe 12, the steel plate 14 and the lower flange 17 are assembled according to the upper flange 11 as a reference, welding is completed, welding stress is eliminated, and inspection is qualified.
Fourth step: and transferring the travelling trolley frame into a machine for machining, and finishing working procedures such as boring, milling, drilling and tapping at the assembly position by a machining center according to the technical requirements of a design drawing, and checking to be qualified.
Fifth step: the walking trolley frame is assembled with the walking wheels and the balance beam.
Through the reinforcing measure, the local strength and rigidity are enhanced, the stress condition of the assembly joint is greatly improved, the stress of the large-sized material taking machine box type traveling trolley is more definite and reliable, the manufacturing process is simple, and the utility model has the advantages of reasonable structure, definite stress, simple manufacture, economy and applicability, safety and reliability.
See the prior art for others.
The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features.
