Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing, and in particular to a device for straightening corner posts of dry bulk containers. Background Technology

[0002] With the increasing demand for dry bulk containers, bulging, deformation, and damage inevitably occur during their use. As the most critical component of a container, protruding or deformed corner posts weaken the container's strength, rendering it unusable and directly impacting the customer's economic interests. Therefore, it is essential to correct protruding or deformed corner posts to ensure their flatness and the normal operation of the dry bulk container.

[0003] Currently, the corner column straightening process requires hoisting the protruding or deformed dry bulk containers onto a platform and using a gantry hydraulic cylinder and hammers to straighten the deformed end. This operation requires specialized personnel for hoisting and straightening. Its drawbacks are: in addition to requiring two people to operate the gantry hydraulic cylinder for corner column straightening, it also requires a dedicated person to operate the lifting equipment to hoist the container onto the platform, increasing the personnel requirement. Furthermore, it requires sufficient space to place the platform, reducing the utilization rate of the factory floor space. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Example 1

[0019] exist Figure 1 , Figure 2 and Figure 3The schematic diagram of this utility model shows a dry bulk container corner post straightening device, including a fixing component, a jack, an upper locking mechanism, and a lower locking mechanism. The fixing component is a vertical beam 1, with a lower locking mechanism connecting plate 2 fixed to the lower part of the vertical beam. An upper locking mechanism connecting plate 3 is sleeved on the upper part of the vertical beam. Both the lower and upper locking mechanism connecting plates are equipped with fixing rods 4, one end of which extends beyond the connecting plate and connects to the container lock head 5. When in use, the handheld jack 6 rests against the vertical beam at one end and against the protruding, deformed corner post at the other end. Two sets of through holes 7 are opened on the upper part of the vertical beam. The positions of the two through holes in each set are alternated. To accommodate the standard container corner post height of 2591mm and the special container corner post height of 2896mm, the upper pin 8 and the lower pin 9 are respectively inserted into the two through holes in the same set. After the upper locking mechanism connecting plate is sleeved on the vertical beam, it moves between the two sets of through holes, and the upper pin and the lower pin are positioned at the upper and lower parts of the upper locking mechanism connecting plate, respectively. Adjusting the position of the upper locking mechanism connecting plate moves the fixing rod and the container lock head on the upper locking mechanism connecting plate, so that the container lock head is inserted into the corner hole of the dry bulk container to be corrected. To improve the moving speed of the dry bulk container corner post straightening device, a traveling mechanism is provided at the lower part of the vertical beam. The traveling mechanism includes a fixed beam, a balance beam, and traveling wheels. One end of the fixed beam 10 is connected to one end of the lower locking mechanism connecting plate, and the balance beam 11 is located at the other end of the lower locking mechanism connecting plate. Both ends of the fixed beam and the balance beam are equipped with traveling wheels 12. To facilitate workers pushing the dry bulk container corner post straightening device, a push handle 13 is provided on the fixed beam.

[0020] In use, this utility model, when applied to the corner post straightening fixture for dry bulk containers, involves a worker using a traveling mechanism to push the straightening device to the protruding or deformed corner post. The container lock heads of both the upper and lower locking mechanisms are then inserted into the corner fitting holes of the dry bulk container to be straightened. After rotating the container lock heads 90°, the corner fitting is locked. A handheld hydraulic jack is then used, with one end resting against a fixed component and the other end against the protruding or deformed area of ​​the corner post for straightening. Once straightening is complete, the lock heads are rotated 90° to release the corner fitting, and the straightening device can then be removed.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
