Description

Semitrailer boxboard welding supporting platform
Technical Field
The utility model relates to a boxboard welded platform technical field, especially a semitrailer boxboard welding supporting platform.
Background
The semi-trailer box plate is generally manufactured by adopting a welding technology, has a large area, is generally horizontally placed on an operation platform for welding, and is hoisted by a crane and transported to the next procedure after welding. Three problems can occur during transportation:
1. the workpieces need to be lifted in the air by using a travelling crane for transportation, so that the potential safety hazard is large;
2. when the traveling crane is used, a clamp is needed, and a workpiece is easy to deform by being clamped by the clamp;
3. the number of the traveling cranes is increased, and the manufacturing cost is increased.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides a semitrailer boxboard welding supporting platform, effectual solved current boxboard production transportation in dangerous, the work piece is yielding, problem that the cost of transportation is high.
The technical scheme includes that the box plate type steel box comprises a rectangular frame, the frame is formed by welding a plurality of section steels, a box plate workpiece is placed at the upper end of the frame, a horizontal flat plate is arranged in the frame, two parallel connecting rods are hinged to the lower end face of the flat plate, the lower ends of the connecting rods are hinged to the frame, the flat plate, the connecting rods and the frame form a parallelogram mechanism, a hydraulic cylinder is arranged between the flat plate and the lower side plate of the frame, a base in the hydraulic cylinder is hinged to the frame, the upper end of a piston rod in the hydraulic cylinder is hinged to the lower end face of the flat plate, and the; the upper end face of the flat plate is provided with a plurality of rollers, the rollers are arranged along the front-back direction, and the flat plate rises to jack up the workpiece through the rollers.
The utility model discloses the structure is ingenious, guarantees boxboard production transportation safety, reduces the deformation of work piece, reduces the driving demand, practices thrift manufacturing cost.
Drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a side view of the present invention.
Detailed Description
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.
The utility model discloses a by figure 1 to 2 show, the utility model discloses a rectangular frame 1, frame 1 is formed by many shaped steel welding, the boxboard work piece is placed to frame 1 upper end, there is the flat board 2 of level form in the frame 1, it has two connecting rods 3 that are parallel to each other to articulate on the flat board 2 lower extreme, connecting rod 3 lower extreme is articulated with frame 1, flat board 2, connecting rod 3 and frame 1 form parallelogram mechanism, there is pneumatic cylinder 4 between flat board 2 and the lower limb of frame 1, the base in the pneumatic cylinder 4 articulates on frame 1, the piston rod upper end in the pneumatic cylinder 4 is articulated with flat board 2 lower extreme, the piston rod stretches out or the shrink can control the rising or the decline of flat board 2; a plurality of rollers 5 are arranged on the upper end face of the flat plate 2, the rollers 5 are arranged in the front-back direction, and the flat plate 2 rises to jack up a workpiece through the rollers 5.
The flat plates 2 are multiple, and the flat plates 2 are uniformly distributed in the frame 1.
In order to enable the box plate to be placed stably and firmly, the upper end face of the frame 1 is welded with the horizontal supporting plate 6, the supporting plate 6 is provided with a plurality of notches which correspond to the rollers one by one, and the flat plate 2 rises to enable the rollers 5 to extend out of the frame 1 from the notches corresponding to the rollers and jack up the box plate workpiece.
It is worth noting that the hydraulic cylinder 4 is inclined and opposite to the inclination direction of the connecting rod 3, a hydraulic station is arranged nearby, and the hydraulic cylinder 4 is controlled by the hydraulic station; the multiple flat plates 2 can effectively reduce the stress of the single hydraulic cylinder 4.
When the welding machine is used, a workpiece is stably placed at the upper end of the frame 1 and is welded, after the welding machine is completed, the hydraulic cylinder 4 is started, the flat plate 2 moves upwards gradually along with the fact that a piston rod in the hydraulic cylinder 4 extends out of a piston cylinder gradually, the roller 5 on the flat plate 2 extends out of the frame 1 through a notch and jacks up the workpiece, the workpiece is pushed at the moment, and the workpiece can move leftwards or rightwards and move to the next procedure.
The utility model discloses make things convenient for the workman to operate, utilize the pneumatic cylinder 4 that articulates in frame 1 to realize lifting in the transportation, need not wait for again to use the driving, need not worry again that the work piece can drop in transporting, eliminated the potential safety hazard, avoided because of the deformation that the driving transportation caused, reduce the dependence to the driving, reduce the cost of transportation.
