By applying the arrangement manner, the invention further discloses an online frame combination method of the large engineering machinery, thereby solving the disorder problem of logistics caused by the branch line frame combination of final assembly lines, reducing secondary lifting, preventing potential safety hazard probably caused by lifting rotation, reducing the labor strength of workers, improving the quality of a combined frame of the front vehicle frame and the back vehicle frame, effectively improving the final assembly efficiency of a loader, enabling the ground of a whole workshop to be clean and comfortable and the logistics to be smooth, and also reducing the cost.
Description
Technical field
The present invention relates to the mounting technology field, particularly a kind of large-scale engineering machinery closes the frame arrangement online, also relates to a kind of frame method of closing online of large-scale engineering machinery, and in relevant narration, modal loading machine describes as example in the engineering machinery.
Background technology
As shown in Figure 1, in engineering machinery field, its assembly technology flow process is to be divided into two lines aspect general assembly at present, article one, be that front/rear frame closes stringing, other one is the complete machine general assembly line, article two, line is vertical placement, and front frame and rear vehicle frame install closing stringing first, then will close the workpiece that frame finishes and transport on the general assembly line by traveling crane.Then enter the general assembly flow process.Closing behind the frame frame assembly reaches the standard grade → lifts to send out and become an assembly → lifting operating oil tank, water tank ... approximately 12 operations are finished final assembly, pipeline all adopts the circulation plates chain, frock clamp is installed on the plate chain with the use that moves in circles of plate chain, and this process is the most general method of using in the present industry.
Along with the in recent years fast development of construction machinery industry, production efficiency to the engineering machinery loading machine proposes requirements at the higher level, and existing assembling process technique scheme need to be innovated improvement, has at present following problem: 1. separated time production, need repeatedly lifting, production efficiency is lower; 2. because in the lifting process, with large-scale vehicle frame workpiece level half-twist; More careful during handling.There is certain potential safety hazard; 2. the logistics supply of two lines is interspersed many, and logistics is relatively more chaotic; 3. owing to recycling, the frock clamp quantity on the sliver is more, and machine equipment is more single, can not adapt to the loading machine of Multiple Type.4. workshop integral body seems more in disorder, and is untidy, and there are two large protruding protectors at the pipeline two ends, affects attractive in appearance unobstructed with logistics.
Summary of the invention
In view of this, one of purpose of the present invention provides a kind of large-scale engineering machinery and closes online the frame arrangement, this mode has been eliminated the mode of movement that existing frock trolley moves in circles with the plate chain, the method that adoption of innovation frock trolley separates with pipeline, the workpiece that i.e. circulation carries the ground drag chain only to be used for the driving sliver carries out assembling work, the frock trolley is then separately by underground auto-returned, by using the new arrangement of this kind, two of purpose of the present invention has provided a kind of large-scale engineering machinery and has closed online the frame method, avoided occurring the potential safety hazard that the handling rotation may cause, reduced labor strength, improve the quality that front frame and rear vehicle frame close frame, Effective Raise loading machine general assembly efficient.
One of purpose of the present invention is achieved through the following technical solutions:
This kind closes the frame arrangement online, that front frame section wiring and rear vehicle frame section wiring are be arranged in parallel in the same direction side by side, the place ahead of an end end at both is horizontally disposed with mechanical general assembly bus, described mechanical general assembly bus and front frame section wiring are all vertical with rear vehicle frame section wiring, under mechanical general assembly bus, be provided with all underground pipelines identical with mechanical general assembly bus of length and bearing of trend in the space, two ends in mechanical general assembly bus arrange respectively vertical conveyor, described vertical conveyor can realize that vertical lift and level push, when an assembling work circulation is finished, when the frock trolley arrives mechanical general assembly bus termination, send into lift by pawling, by the horizontal drive apparatus on the lift dolly is pulled to the fixed position, then drop to the delivery port of underground pipeline, by the underground initiating terminal that is sent to mechanical general assembly bus, after by the vertical conveyor of initiating terminal dolly being pulled to the fixed position of hoistable platform, this vertical conveyor rises, the frock trolley is delivered to the starting point entrance of ground transport line, at last it is pushed into assembly line, finish a circulation.
Further, the hydraulic lifting bracing frame also is set on production line, described hydraulic lifting bracing frame is arranged on the production line by the supporting plate of two tape guides, by the hydraulic-driven lifting, before closing frame, can rise the temporary supporting that is used as rear vehicle frame, after closing online frame and finishing, the frock trolley is put to the front-rear axle of vehicle frame, then the hydraulic lifting bracing frame steadily is down to ground, meanwhile vehicle frame also drops down onto in the bracket of frock trolley, continues to enter the next flow process of production line.
Two method of purpose of the present invention is to adopt foregoing arrangement to carry out machinery to close online frame, may further comprise the steps:
Step 1: the frock trolley is pushed to the starting point of production line by underground conveying by hoistable platform;
Step 2: the chain that production line closes the frame section is pulled to the frock trolley and closes the frame station, and one of them trolley is placed on the vehicle frame front-rear axle Support Position;
Step 3: start button, rise the hydraulic lifting bracing frame to correct position;
Step 4: will be wait rear vehicle frame handling the lifting on the plate to the hydraulic lifting bracing frame of closing frame;
Step 5: by driving with the front frame handling to lifting plate and rear vehicle frame closes frame;
Step 6: after closing frame and finishing, the frock trolley of front is pulled to vehicle frame propons below;
Step 7: slowly steadily fall the hydraulic lifting bracing frame, closed the frame assembly that frame is finished, in the V-type groove of the front and back frock trolley below slowly dropping down onto;
Step 8: put down the hook of dolly, drive by chain, vehicle frame continues to move ahead with dolly, enters next operation.
The invention has the beneficial effects as follows:
Method for arranging of the present invention has been eliminated the mode of movement that existing frock trolley moves in circles with the plate chain, the method that adoption of innovation frock trolley separates with pipeline, and utilize this kind arrangement to close the method for frame by improving mode of movement, simultaneously innovation and application online hydraulic lifting bracing frame, solved the staggered chaotic problem of logistics that general assembly line distributing box frame causes, reduced secondary hoisting, avoided occurring the potential safety hazard that the handling rotation may cause, reduced labor strength, improve the quality that front frame and rear vehicle frame close frame, Effective Raise general assembly efficient, make whole mill floor neatly salubrious, logistics is unimpeded; Also reduce simultaneously the driving energy consumption of chain, joined tens cover frock trolleys by an original line and be reduced to tens covers, reduced cost.
Other advantages of the present invention, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being apparent to those skilled in the art to investigating hereinafter, perhaps can be instructed from the practice of the present invention.Target of the present invention and other advantages can realize and obtain by following specification and claims.
