Description

Technical Field

[0001] The utility model relates to an anti-expansion box mechanism for a container overturning machine. Background Art

[0002] A container turning machine is a device used to lift a container and raise the door end of the container to facilitate filling the container with bulk materials. In the process of filling the container with bulk materials, since the container is tilted at a certain angle, the filled bulk materials are concentrated on the side wall of the rear end of the container tilted to the bottom, resulting in stress concentration on the side wall of the rear end of the container, which is easy to burst the container. Chinese patent application number 201921500014.4 discloses a container vertical packing anti-bulging deformation mechanism, characterized in that it comprises a turning platform (1) and a clamping arm (2) symmetrically hinged on both sides of the turning platform (1), the clamping arm (2) is a right-angled arm, its short pressing arm (21) extends to the side of the bottom surface of the container body of the flat turning platform of the container, the hinge point (10) is located on the pressing arm (21), and the long clamping arm (20) is a container side clamp body extending upward with its root outside the hinge point (10). This mechanism can avoid the occurrence of bulging deformation during packing. However, the invention still has the following disadvantages: the clamping arms (2) symmetrically hinged on both sides of the tilting platform (1) are right-angle arms. When clamping a container, the clamping arms (2) must be in right-angle contact with the container, that is, the width of the container clamped by the clamping arms (2) is fixed. The mechanism cannot adapt to the anti-expansion box operation of containers of various widths. Utility Model Content

[0036] like Figures 1 to 4 As shown, the utility model provides an anti-expansion box mechanism for a container overturning machine, comprising:

[0037] A turning platform 10 is supported on the ground by a turning frame 1; the turning frame is a hydraulic mechanism arranged in a conventional turning platform, which is used to support the turning platform and the container for synchronous turning, so as to lift the container door to a certain height, and then carry out the bulk material packing operation; a pair of support frames 20, which are correspondingly arranged on both sides of the turning platform, and the lower ends of the pair of support frames are hingedly arranged on the side edges of the turning platform; any support frame is a rectangular frame structure; any support frame includes a receiving groove 201, which is formed on the first side wall of any support frame facing the turning platform; a pair of lining frames 30, which are respectively detachably embedded in the receiving grooves of a pair of support frames, the front end face of any lining frame of a pair of lining frames is flush with the plane where the first side wall of any corresponding support frame is located, and the rear end face of any lining frame is directly opposite to the bottom of the corresponding embedded receiving groove; two groups of rods 301, which are respectively arranged in a pair of lining frames A pair of hydraulic cylinders Ⅰ 40 are respectively arranged on the outside of a pair of support frames, and the bases of the pair of hydraulic cylinders Ⅰ are hinged on the flip platform, and the front ends of the piston rods of the pair of hydraulic cylinders Ⅰ are hinged to the second side walls of the pair of support frames facing the outside of the flip platform; and a pair of hydraulic cylinders Ⅱ 50 are respectively arranged on the outside of a pair of support frames, and the pair of hydraulic cylinders Ⅱ are respectively arranged perpendicular to the pair of support frames, and the front ends of the piston rods of any hydraulic cylinder Ⅱ are hinged to any corresponding set of rods, so as to facilitate the skewing of the pair of liner frames to a certain extent to adapt to the side walls of the container, and the bases of any hydraulic cylinder Ⅱ extend outward and are fixed on the pair of support frames through the fixing frame 7, and any hydraulic cylinder Ⅰ and any hydraulic cylinder Ⅱ on the same side do not contact each other. The two sets of rods are used to enhance the mechanical structure of a pair of liner frames, ensure the clamping effect, and at the same time, provide a suitable hinge position for the pair of hydraulic cylinders Ⅱ. The fixing frame is not only used to fix the base of a pair of hydraulic cylinders II, but also used to provide support force for a pair of inner liner frames hingedly arranged thereon, so as to push the pair of inner liner frames away from the receiving grooves of a pair of support frames or pull them back into the receiving grooves.

[0038] A pair of support frames, a pair of inner lining frames and two groups of rods are all made of metal, with a simple structure and stable support.

[0039] In this solution, when there is no container on the flip platform, the pair of support frames are in a relatively open state, and a pair of hydraulic cylinders I support the pair of support frames on both sides and keep them open at a certain angle to provide sufficient space for easy access of containers;
