The utility model provides a container bottom protective box structure as shown in fig. 1-3, which comprises four protective box assemblies 100 arranged on the same plane, wherein the protective box assemblies 100 comprise fixed supports 4 for positioning the integral protective box assemblies 100; a crank arm 3 hinged with the fixed support 4 through a hinge hole 8 on the fixed support 4; one end of the crank arm 3 is hinged with a crank 7, and the crank 7 is rigidly connected with an adjusting block 1; the crank arm 3 is also hinged with the telescopic end of the oil cylinder 2. In the whole operation process of the container loading and unloading system, after the matched lifting appliance finishes the action of grabbing the container, the structure of the container loading and unloading system starts to be started before lifting or overturning the container, and the lifting appliance equipment enters the actions of follow-up transferring or overturning and the like for the container after the action is finished by attaching the bottom protection mechanism adjusting block 1 to the container for lifting and supporting through the telescopic action of the bottom protection mechanism oil cylinder 2 of the protection assembly 100. The overall case structure is composed of four case assemblies 100 distributed at the bottom of the container, which adopts a high-strength steel structure, and can cope with the heavy load of the container. The fixing support 4 is mainly used for fixing the protective box assembly 1 on other main structures, and can be used for installing other mechanisms, and the flat plate 6 arranged on the upper part of the protective box assembly can strengthen the integral structural strength of the fixing support 4, so that the stability of the oil cylinder 2 in working is facilitated, and other structures can be directly installed on the protective box assembly. The crank arm 3 has a curved shape, and its entirety may be welded or cast for maintaining structural strength. One end of the crank arm 3 is hinged on the fixed support 4, and the other end of the crank arm takes the hinge hole 8 as a circle center to perform rotary motion, so that the container is lifted at different positions. The crank 7 and the adjusting block 1 are arranged in a hinged manner, so that the adjusting block 1 has a certain swing amplitude when contacting the bottom of the container, and the container is matched with the unevenness of the bottom of the container or is cheap due to the asynchronous mechanical structure. The two ends of the crank 7 are both rigidly connected with the adjusting blocks 1, when the two adjusting blocks 1 of the same protective box assembly 100 are simultaneously contacted with the bottom of the container, the adjusting principle is realized by rotating the crank 7 around the hinge hole of the hinge connection of the bottom of the crank on the crank arm 3 according to the deviation condition of the contacted bottom of the container.

In this patent, the stiff end of hydro-cylinder 2 pass through-hole 9 on the fixed support 4 with the fixed support 4 is articulated to be connected. The cylinder 2 provides power to enable the crank arm 3 to extend, retract and move relative to the fixed support 4, so that the position is adjusted when the container is lifted. As other embodiments, the present cylinder may be replaced by other structures to achieve the same effects, for example: telescopic boom structure, rack and pinion structure, etc.

In this patent, the lower part of the front end of the crank arm 3 is also rigidly connected with a bottom plate 5. The bottom plate 5 can be welded and arranged, and is used for reinforcing the structural strength of the crank arm 3 and enabling the crank 7 to be arranged on the bottom plate, and the bottom plate 5 and the hinge shaft of the crank 7 bear the gravity from the bottom of the container, which is received by the adjusting block 1, so that the container is lifted.

In this patent, the crank 7 is adjusted accordingly according to the different contact of the adjusting block 1 on the upper part to the bottom surface of the container. When the adjusting blocks 1 on the crank 7 are respectively subjected to the gravity applied by the bottom surfaces of different containers, the crank 7 can be adjusted left and right by taking the bottom hinge shaft as the shaft because the bottom of the crank 7 is of a hinge structure until the stress of the two adjusting blocks is uniform. When the four protective case assemblies 100 are operated simultaneously, the bottom of the container can automatically find the balance position, and the balance fixing position at the moment is close to the optimal value theoretically, so that the lifting protection of the container is finished.

In this patent, the crank arm 3 can be at least maintained at a first position and a second position under the push-pull force of the oil cylinder 2, when the four protective box assemblies 100 move simultaneously to do work, the single crank arm 3 can move to the corresponding position and be maintained, when the container finishes actions such as lifting and overturning, the oil cylinder of the four protective box assemblies is retracted, at this time, each crank arm 3 returns to the initial position and waits for the next operation.

The cylinders of the four cage assemblies 100 are independently disposed. This patent technical scheme still includes the hydraulic system who provides hydraulic power. The hydraulic system can be designed into the oil cylinder 2 which is communicated with the four protective box assemblies 100 at the same time, under the condition of constant output pressure, the protective box assemblies 100 at four positions are subjected to the same push-pull force, floating lifting is generated on the whole container, and the container is stably lifted and turned over through the resultant force between the protective box assemblies 100 under the action of self gravity, so that the deviation caused by mechanical asynchronism can be effectively eliminated.

When the device is used, in the whole container loading and unloading operation process, after the container lifting tool finishes the container grabbing action, power is transmitted to the oil cylinder 4 of the bottom protective box assembly 100 through the hydraulic system to perform stretching movement, the crank arm 3 moves by taking the hinge hole 8 on the fixed support 4 as the circle center, meanwhile, the adjusting block 1 receives the gravity action of the bottom of the container, and the balance position is found through the swinging of the crank 7 to lift the container. Lifting of the bottom of the container is accomplished by the resultant force between the integral guard box assemblies 100. Then the lifting appliance equipment enters a subsequent action to transfer or overturn the container.

The principle of the utility model is as follows: through setting up the combined action of crank 7 that can swing and crank arm 3 that can extend through the hydro-cylinder effect, form floating connection structure for the container passes through gravity action, finds the equilibrium point, accomplishes the comprehensive protection of lifting to the container.

Finally, it should be noted that: the foregoing description of the preferred embodiments of the present utility model is not intended to be limiting, but rather, although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
