Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material handling and relates to a railway container unloader. Background Art

[0002] In modern logistics transportation, railway container transportation is widely used due to its high efficiency and convenience. However, in the container unloading process, current technical solutions have many deficiencies, seriously affecting the unloading efficiency and cost control.

[0003] Traditional railway container unloading methods mainly rely on gantry container unloaders to transfer containers to trucks, and then unload through the automatic unloading platforms of the trucks. This unloading process is cumbersome and complex, not only increasing the frequency of use of transport vehicles but also greatly increasing the demand for operators, resulting in high transportation costs. In addition, this unloading method also brings many inconveniences in on-site production management, such as vehicle scheduling and personnel coordination issues, which greatly limit the improvement of unloading efficiency.

[0004] Another unloading solution is to use a modified train car dumper for container unloading. However, this solution has poor applicability to containers with diverse forms. Due to the different sizes, weights, and loading methods of containers, modified car dumpers often have difficulty adapting to all types of containers, thus limiting their wide promotion and application. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a railway container unloader to solve the existing problems.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A railway container unloader includes a container unloading workshop, support beams arranged on both sides of the container unloading workshop, a gantry container unloader straddling between the support beams through tracks, and a railway container train arranged in the container unloading workshop.

[0027] Please refer to Figures 1 to 3, is a railway container unloader, including a container unloading workshop, support beams arranged on both sides of the container unloading workshop, a gantry container unloader 1 straddling between the support beams through tracks, and a railway container train 6 arranged in the container unloading workshop. A special container lifting device 2 for lifting containers is installed at the bottom of the gantry container unloader 1; an on-board hopper 5 is also equipped in the container unloading workshop. A dust removal cover 4 and a dust remover 3 are arranged at the top of the on-board hopper 5, and a discharging device 7 under the bin is arranged at the bottom. An inlet is opened on the dust removal cover 4, and an external conveyor belt 8 is equipped at the outlet of the discharging device 7 under the bin. The gantry container unloader 1 includes a trolley traveling mechanism and a crab traveling mechanism. The trolley traveling mechanism moves longitudinally along the support beam, and the crab traveling mechanism is arranged under the trolley traveling mechanism and can move laterally. A cross beam is arranged between the support beams, and the on-board hopper 5 is fixedly installed on the cross beam. A dry fog dust suppression device is also arranged at the top of the dust removal cover 4, and dust can be suppressed by spraying when the on-board hopper 5 receives materials. The special container lifting device 2 can be installed alone in one group or installed in multiple groups side by side to improve the unloading efficiency, and has functions of moving up and down and rotating left and right. The dust remover 3 is connected to a dust suction system through a dust removal pipeline. A box door lock is arranged on the box door of the container, and a door pressing mechanism for opening the box door lock is equipped outside the box door lock. A camera with a positioning function is arranged on the container lifting device. A weighing unit (such as an electronic belt scale) is arranged on the discharging device 7 under the bin to measure and count the discharging amount in real time.

[0028] In this embodiment, this device is configured with a weighing unit. A number of weighing sensors are configured on the installation platform of the on-board hopper 5 to achieve static weighing during the interval time of container lifting and transporting.

[0029] In this embodiment, the special container lifting device 2 can rotate left and right (>= ±105°) and tilt up and down (>= ±60°); this structure is an existing mature mechanical finished product structure and is not the focus of this application, so it will not be elaborated here.

[0030] When the utility model is in use, the gantry container unloader 1 first moves longitudinally along the support beam to a specified position through the trolley traveling mechanism, and the trolley traveling mechanism moves transversely under the trolley to accurately align with the container to be unloaded; the special container spreader 2 (which can be a single group or multiple groups assembled together) starts, adjusts to the best grasping position through the functions of moving up and down and rotating left and right, and then the special container spreader 2 accurately grasps the container door. The special container spreader 2 together with the container is lifted and moved above the container unloading workshop. During the process, the camera on the spreader starts to perform precise positioning to ensure safe operation. Immediately afterwards, the container is slowly lowered above the on-board hopper 5, and the special container spreader 2 tilts. At this time, the container door lock is opened manually or automatically, and the material poured out from the container is received through the feeding port. At the same time, the dust removal cover 4 at the top of the hopper and the dust remover 3 start to work, and the dry fog dust suppression device at the top of the dust removal cover 4 starts to spray fine water mist to suppress the diffusion of dust and ensure a clean working environment. The material enters the discharging equipment 7 under the bin through the on-board hopper 5. This equipment includes a weighing unit, a gate and a chute. The material is first accurately measured through the weighing unit during the conveying process. According to needs, the gate and the chute adjust the flow rate of the material to ensure stable and uniform conveying onto the external conveying belt 8. The material is conveyed to the subsequent treatment or storage area through the external conveying belt 8. After the container is unloaded, the spreader releases the container and returns to the standby position to prepare for the next operation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
