Description

Self-propelled container reversing car

Technical field

The invention relates to the technical field of lifting and unloading mechanical equipment, in particular to a container turning vehicle capable of handling loading and unloading of materials (especially various bulk materials), in particular to a self-operating movement, a box loading and unloading pile Self-propelled container reversing vehicles with various functions such as squatting, flipping, door opening and closing and dynamic weighing display.

Background technique

At present, containerized transportation at home and abroad is vigorously promoted, vigorously developed and widely used. At the same time, due to factors such as improved environmental protection requirements, increased transshipment costs and serious loss in the middle, the development of containerized transportation of bulk materials is faster and the prospects are unlimited. However, the first question to be considered is how to load and unload the materials (especially bulk materials) into and out of the container, especially how to safely and efficiently realize the vertical movement of the container (uploading) and downward (unloading), to meet the high efficiency and safe operation. Claim.

The main methods used at home and abroad: (1), the traditional flip platform with fixed base with wheel loading crane or large gantry lifting equipment to complete the required operations. The disadvantage is that the space is occupied by a large space, the investment cost is high, the safety performance is low, and the operation is not easy. Under normal circumstances, loading and unloading cannot share the same set of equipment and must be realized separately. (2) Adopting one-way or two-way container turning machines which are currently used more, such as "a container turning machine" disclosed by CN202806496U and a "two-way container turning machine" disclosed by CN104860247A, and the like. Although the performance of this type of turning machine has been greatly improved, there are still some shortcomings: fixed or passive towing can not run by itself. The movement flexibility is poor. Most of them only have the function of loading or unloading one-way operation, but they are not compatible. The loading, unloading, transportation and stacking operations of the container heavy-duty box require manual operation and can not control the opening width of the box door. They rarely have dynamic weighing display function, and most of them are limited to 20-foot box work.

To this end, the present invention devises a self-propelled container reversing vehicle capable of overcoming the above-mentioned disadvantages while having various functions such as self-operating movement, box loading, unloading, stacking, turning, door opening and closing, and dynamic weighing display.

For example, the lifting device is composed of a lifting mechanism composed of an upper column and a lower column, and the upper column is hollow, and the inner column is hollow and has an inner diameter slightly larger than an outer diameter of the lower column to make the telescopic column extendable; The lifting mechanism is a lifting cylinder, and the upper end of the lifting cylinder is fixed on the frame and the lower end is fixed to the lower column. More preferably, the lower part of the two-wheel side is further provided with a base fixed to the lower part of the two pillars on the two-wheel side, and the lower end of the lifting cylinder is fixed on the base.

More preferably, the self-propelled container reversing vehicle further includes a weighing display system consisting of a dynamic weighing sensor mounted in the upper pin of the upper and lower bearing supports of the lifting mechanism and a display control system mounted on the upper part of the machine room cover assembly. composition. In the material loading operation, the dynamic weight information and the eccentric load detection result of the loaded material can be obtained through the process of transmission amplification operation through the change signal collected by the dynamic weighing sensor installed in the pin, and reflected in the display control in real time. In the system, the dynamic real-time weighing display process is completed to avoid and control the overload, underload and eccentric load of the package, ensuring efficient production and safe operation.

Most preferably, the self-propelled container reversing vehicle further includes a radio remote control coupled to the power control system via a wireless signal, radio frequency or Bluetooth.

The working principle of the self-propelled container reversing car is as follows:
