Abstract
The utility model discloses an unloading system for an integral crawler crane. In the unloading system for the integral crawler crane, a crawler frame (1) is welded together with a vehicle frame (2) to form an integral structure. The unloading system has the following technical effects: the vehicle frame and the crawler frame are welded integrally with good welding process on the basis of ensuring the welding intensity; the vehicle frame trends to be simplified in design, and has better force carrying manner and better stability; the limitations on mounting conditions and transportation conditions are reduced, the mounting difficulty is decreased, and the transportation cost is reduced; the unloading system is simple and compact in structure and strong in practicability and carrying capacity; installation steps are reduced to a great extent; and the work efficiency is improved.
Description
Technical field
The utility model relates to engineering machinery field, the following truck system of particularly little tonnage hoisting crane.
Background technology
Along with the development of technology, body frame structure for automotive spare is tending towards lightweight, and the weight-lifting equipment market demand is also increasing day by day.For promoting lifting performance, present little tonnage crawler crane frame system and frame adopts dual mode to design: the one, and the split of traditional class connects, and the 2nd, the integral solder of innovation class.
What the following truck system of the crawler crane of tradition class adopted is that split connects, be that vehicle frame and track frame are linked together by forms such as bearing pin or active sections, this mode is when getting off installation and transportation, in the certain size of defined, cause transporting over-wide easily, increase traffic cost, process is all comparatively complicated.
Summary of the invention
The purpose of this utility model is: truck system under the present little tonnage crawler crane all is vehicle frame and track frame divided mode, combines by bearing pin or overlapping mode.This form is suitable for the vehicle of arrow gauge operation Bg of walking, and considers to disassemble the transportation factor because of deadweight.Vehicle frame and track frame junction be the weak link of structural bearing often, therefore will do reinforcement herein usually, makes dead load bigger, and is prone to stress concentration and fatigue phenomenon.For the good transmission of load, for the little tonnage crawler crane that does not need to become gauge, if vehicle frame and track frame formula as a whole, structure is more simple, reduces junction stress concentration phenomenon, improves structure service life.
In order to achieve the above object, the technical scheme that provides of the utility model is: truck system under a kind of entire track hoisting crane is provided.Truck system is with track frame and vehicle frame weld together under the described entire track hoisting crane, forms an one-piece construction.
Wherein, described vehicle frame is " X " shape structure, and the both sides of vehicle frame are symmetrically welded with track frame.
Wherein, described vehicle frame and pivoting support junction are welded with two-layer annulus riser or polygon riser; Described track frame and vehicle frame weld will have the gusset of corresponding Type of Welding.
The utility model beneficial technical effects is: vehicle frame and track frame are realized integral solder, and on the basis that guarantees weld strength, welding process is better; In the body frame structure for automotive design, be tending towards oversimplifying, stress form is better, and stability is better; Reduce the restriction on mounting condition and the traffic condition, reduce installation difficulty, reduce traffic cost; Simple and compact structure, practical, load-carrying capacity is strong, has reduced installation steps significantly, increases work efficiency.
Description of drawings
Fig. 1 is the utility model entire track hoisting crane system construction drawing of getting off.
Fig. 2 is the body frame structure for automotive figure of truck system under the utility model entire track hoisting crane.
The specific embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
The utility model is to be in particular the novel truck system (with reference to Fig. 1, Fig. 2) down of little tonnage crawler crane design-calculated.Vehicle frame 2 and track frame 1 connect together by welding, and than overlap joint or bearing pin connection mode, the cross section, junction is big, and the torsion resistant and bending resistant ability is strong, and the welding manner compact conformation, the impact load that does not have the junction to produce because of the gap.Need not disassemble during transportation, reduce fixing link, reduce the less important work cost.
Observed data: (1) 100% forward hangs and carries result of calculation: σ max=77.3MPa, Δ max=0.8mm.
(2) 110% forwards hang and carry result of calculation: σ max=88.6MPa, Δ max=0.9mm.
(3) 125% operating condition of test result of calculations: σ max=105MPa, Δ max=1.1mm.
Conclusion, by the analysis of stress cloud atlas, three kinds of operating modes stressed all within tolerance zone meets the demands.
Above content be in conjunction with optimal technical scheme to further describing that the present invention did, can not assert that the concrete enforcement of invention only limits to these explanations.Concerning the general technical staff of the technical field of the invention, under the prerequisite that does not break away from design of the present invention, can also make simple deduction and replacement, all should be considered as protection scope of the present invention.
