Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a lower end beam shaping device. Background Technology

[0002] With the continuous expansion of container shipping business, dry bulk containers are becoming increasingly popular. Since dry bulk containers are mostly used outdoors, they require frequent lifting and hoisting by cranes, and occasional accidents such as bumps and knocks may occur. This can cause plastic deformation of the lower beams at the front and rear ends of the container. The deformed lower beams are weak in strength and rigidity, have poor load-bearing capacity, and are out of dimensional tolerance. If the deformation continues, there is even a risk of damage to the container.

[0003] Currently, the solution to the deformation of the lower beam is to return the container to the manufacturer or a professional repair shop, where the deformation can only be corrected using the facilities in the factory, which wastes a lot of time and manpower and is costly. Utility Model Content

The limiting block is fixed to the support base, on which an L-shaped shaping base is placed, and the shaping base is limited by the limiting block. One side of the L-shaped shaping base is integrally formed with the hook plate pressure head, which is bent inwards. A hydraulic cylinder is fixed to the other side of the L-shaped shaping base, with the cylinder positioned higher than the hook plate pressure head. The fixed end of the telescopic connecting rod is fixed to the support base, and the telescopic end of the telescopic connecting rod is connected to the lower part of the shaping base.

[0007] The outward convex shaping mechanism includes a crossbeam, container locking components, and a mechanical jack. Container locking components are installed at both ends of the crossbeam. During shaping, the lower ends of the two container locking components are inserted into the corner pieces at both ends of the lower beam to be shaped. The mechanical jack is placed between the crossbeam and the lower beam to be shaped, and its left and right position is adjusted to position it at the outward convex position of the lower beam.

[0018] Example 1

[0019] exist Figures 1 to 3 The schematic diagram of this utility model shows that the dry bulk container lower end beam shaping device includes an inner concave shaping mechanism and an outer convex shaping mechanism.

[0020] The concave shaping mechanism includes a support base, a telescopic connecting rod, a shaping base, a hydraulic cylinder, a hook plate pressure head, and a limiting block. The limiting block 1 is fixed to the support base 2, and an L-shaped shaping base 3 is placed on the support base, with the shaping base limited by the limiting block. One side of the L-shaped shaping base and the hook plate pressure head 4 are integrally formed, with the hook plate pressure head bent inwards. A hydraulic cylinder 5 is fixed to the other side of the L-shaped shaping base, with the cylinder positioned higher than the hook plate pressure head. The fixed end of the telescopic connecting rod 6 is fixed to the support base, and the telescopic end of the telescopic connecting rod is connected to the lower part of the shaping base. A support plate 7 is fixed to the lower part of the support base, and casters 8 are provided under the support plate. A push rod 9 is fixed to one side of the support base.

[0021] The outward convex shaping mechanism includes a crossbeam, container locks, and a mechanical jack. Container locks 11 are provided at both ends of the crossbeam 10. During shaping, the lower ends of the two container locks are inserted into the corner pieces at both ends of the lower beam to be shaped. The mechanical jack 12 is placed between the crossbeam and the lower beam to be shaped. The left and right positions of the mechanical jack are adjusted to position it at the outward convex position of the lower beam.

[0022] In use, when the lower end beam 13 is concave, the container is lifted and placed on a support frame. The concave shaping mechanism is pushed to the concave part of the lower end beam, the hook plate pressure head extends into the bottom frame of the lower end beam, the hydraulic cylinder is activated to raise the hook plate pressure head, and the concave shaping mechanism is pulled back so that the hook plate pressure head hooks onto the inner side of the lower end beam. Then, the hydraulic cylinder is activated to press down the lower end beam and continue to apply force. The reaction force of the hook plate pressure head can correct the concave shape of the lower end beam. When the lower end beam is convex, the container is lifted to a flat surface and placed stably. The convex shaping mechanism is pushed so that the locking parts of the two containers are aligned with the holes at the ends of the corner pieces of the lower end beam. After insertion, the locking parts are locked. Then, a mechanical jack is placed horizontally between the convex part of the lower end beam and the crossbeam, using the crossbeam as the support to push back the convex lower end beam.
