Detailed Description

As shown in fig. 1 to 6, embodiment 1: comprises a flatbed vehicle body 8; the top of the vehicle body is rotatably connected with a loading platform 9; the front side and the rear side of the loading platform 9 are respectively provided with an outward extending telescopic folding arm, and the left side and the right side of the loading platform 9 are respectively provided with a rotary folding arm; a slide way is arranged in the loading platform 9, and the telescopic folding arm is connected with the slide way in a sliding manner; when in the extending state, the telescopic folding arm slides out of the loading platform 9; when in the recovery state, the telescopic folding arm retracts into the loading platform 9; the rotary folding arm is rotatably connected with the side surface of the loading platform 9. The setting of slide moves scalable book arm and stretches out to both sides position around, makes steel billet 13 deposit the area increase, with the crane with 13 handling of steel billet to rail operation dolly on, the operation dolly removes, runs steel billet 13 to outer position of falling the buttress, realizes that steel billet 13 transports fast, transports the completion back, scalable book arm resumes the normal position, alleviates on-the-spot staff and haulage vehicle operation space, later will transport the dolly and reach the assigned position.

The telescopic folding arm: a front folding arm arranged at the front side of the loading platform 9 and a rear folding arm arranged at the rear side of the loading platform 9; the two telescopic folding arms have the same structure and respectively comprise two parallel extension rods 4 and a cross arm connected with the first ends of the two extension rods 4, and the second ends of the two extension rods 4 extend into the slideway and are in sliding connection with the slideway. When unfolded, the two extension bars 4 slide out of the loading platform 9. The cross section of the extension bar 4 is square or rectangular, so that the top surface is a plane, which is more beneficial to the placement of the billet 13. Upon retraction, the two extension bars 4 slide into the loading platform 9. The end part of the extension rod 4 is provided with a limiting block to prevent the extension rod 4 from sliding out of the slideway, which is not repeated herein. The cross arm comprises an Contraband-shaped frame 1 with an outward opening, a left cross arm 2 and a right cross arm 3 which are installed in the Contraband-shaped frame 1, wherein the left cross arm 2 and the right cross arm 3 are symmetrically arranged, and one ends of the left cross arm and the right cross arm are rotatably connected with the Contraband-shaped frame 1. When the frame is unfolded, the left cross arm 2 and the right cross arm 3 rotate to the outside of the Contraband-shaped frame 1; when retracting, the left arm 2 and the right arm 3 are rotated and retracted into the Contraband-shaped frame 1. When the left cross arm 2 and the right cross arm 3 are in the unfolded state, the left cross arm 2 is positioned on the left side of the Contraband-shaped frame 1, the right cross arm 3 is positioned on the right side of the Contraband-shaped frame 1, and the left cross arm 2, the Contraband-shaped frame 1 and the right cross arm 3 form a straight line.

The folding arm structure is rotated: the left folding arm 5 is arranged on the left side of the loading platform 9, and the right folding arm 6 is arranged on the right side of the loading platform 9; the left folding arms 5 and the right folding arms 6 are two, the two left folding arms 5 are symmetrically arranged, and the two right folding arms 6 are also symmetrically arranged. And the left folding arm 5 and the right folding arm 6 are identical in structure, one end of each of the two folding arms is rotatably connected with the loading platform 9 through a rotating shaft, the other end of each of the two folding arms is provided with a groove for accommodating the material blocking turning plate 7, and the material blocking turning plate 7 is rotatably connected to the groove. A material blocking shaft is arranged in the groove, and one side of the material blocking turnover plate 7 rotates in the groove for 90 degrees through the material blocking shaft; when the material blocking turnover plate 7 rotates into the groove, the material blocking turnover plate 7 does not completely cover the groove. Leaving a gap for manual actuation of the flap. When the material blocking turning plate 7 is used for placing the steel billet 13 on the folding arm (the left folding arm 5 or the right folding arm 6), the material blocking turning plate 7 is perpendicular to the left folding arm 6 and the right folding arm 6 after rotating for 90 degrees, and the effect of limiting the falling of the steel billet 13 is achieved.

The cross arm, the loading platform 9, the left folding arm 5 and the right folding arm 6 are in the same plane, namely the height above the ground is consistent; when the steel billet 13 is supported, the supporting structure is in a plane, so that the gravity of the steel billet 13 can be better borne, and the acting points are uniform.

The slewing bearing structure is as follows: the upper loading platform 9 is connected with the flat car body 8 by a rotary supporting disc 12. The inner ring of the rotary supporting disc 12 is connected with the upper loading platform 9, and the outer ring of the rotary supporting disc 12 is connected with the flat car body 8. The rotary support disc 12 is connected to a gear drive which is connected to a motor.

Specifically, in the operation of the billet 13 transfer trolley of the specific embodiment: firstly, adopt the design of the arm mode of folding, open the arm of folding and can increase the loading end of steel billet 13, be favorable to increasing steel billet 13 and transport quantity, can satisfy the transportation of longer steel billet 13 simultaneously.

And the folding arm adopts a retractable mode, so that the transportation trolley occupies a small area of the ground when not in work. Is favorable for shuttling in a narrow space.

And a rotary supporting structure is arranged between the loading platform 9 and the lower support 11 (platform trolley), so that the condition that the steel billet 13 needs to be turned around by 90 degrees in the process of transferring the steel billet 13 is facilitated.

And fourthly, the unfolding and the folding arm are manually completed, (the unfolding and the folding can be realized in an electric or hydraulic mode).

It should be understood that the above detailed description of the present embodiment is only used for illustrating the present embodiment and is not limited to the technical solutions described in the present embodiment, and those skilled in the art should understand that modifications or equivalent substitutions can be still made on the present embodiment to achieve the same technical effects; as long as the use requirements are met, the protection scope of the specific embodiment is within the protection scope.
