Description

Technical Field

[0001] This utility model relates to the field of short-distance loading and unloading mobile equipment for logistics, and in particular to a simple loading and unloading mobile equipment for container cargo. Background Technology

[0002] In the container transportation process, after the container is transported to the designated location, further loading, unloading and moving operations are required. Currently, the loading, unloading and moving of container mainly rely on large specialized equipment such as gantry cranes and heavy forklifts.

[0003] However, the purchase and maintenance costs of large equipment are high, making it difficult for small and medium-sized logistics companies to afford. Moreover, these equipment require fixed installation sites or dedicated driving lanes, with extremely stringent requirements for ground flatness and load-bearing strength, making them unsuitable for simple sites such as temporary freight points and rural logistics stations. On the other hand, the operation of large equipment requires professional personnel and involves cumbersome procedures. In scenarios involving short-distance, small-batch container movement, there is a waste of resources due to "using large equipment for small purposes," which prevents rapid loading and unloading and results in extremely low operational efficiency. Furthermore, existing simple tools such as manual hydraulic jacks have limited functionality, only enabling partial lifting and lowering, and cannot complete simultaneous movement. Multiple equipment switching is required during operation, which is not only inefficient but also raises safety concerns. Utility Model Content

[0004] To address the inconvenience of existing container loading and unloading operations in short-distance, small-batch scenarios, this utility model provides a simplified container loading and unloading mobile device.

[0005] The technical solution of this utility model is achieved through the following scheme: a simple loading and unloading mobile device for container cargo, including a steering hydraulic telescopic transport frame, a following hydraulic telescopic transport frame, and a fixed beam. The steering hydraulic telescopic transport frame is fixedly connected to the following hydraulic telescopic transport frame through the fixed beam arranged opposite to each other. A hydraulic pump station and an energy storage battery are provided on the side of the steering hydraulic telescopic transport frame away from the fixed beam. The hydraulic pump station is connected to the steering hydraulic telescopic transport frame and the following hydraulic telescopic transport frame through oil pipes. The energy storage battery is electrically connected to the steering hydraulic telescopic transport frame and the hydraulic pump station. Loading brackets are fixedly installed on the inner sides of both ends of the fixed beam.

[0006] Through the above technical solutions, the hydraulic telescopic transport frame, in conjunction with the fixed beam, achieves a stable structure with hydraulic telescopic function, integrating lifting and moving functions. It eliminates the need for equipment switching, is easy to operate, and can be operated by a single person, significantly improving work efficiency. It is adaptable to containers of different specifications, solving the pain points of traditional simple tools' limited functionality and poor adaptability. Furthermore, it has low maintenance costs and requires no complex site conditions. Multiple mounting brackets provide mounting points for the equipment, offering reliable basic support for subsequent cargo transportation.

[0007] Preferably, the steering hydraulic telescopic transport frame includes symmetrically arranged first hydraulic telescopic outriggers, a first transverse hydraulic telescopic beam, and hydraulically driven steering wheels. The first transverse hydraulic telescopic beam is screwed between the telescopic ends of the two first hydraulic telescopic outriggers. The hydraulic pump station and energy storage battery are fixedly installed on the side of the first transverse hydraulic telescopic beam away from the fixed beam. Hydraulically driven steering wheels are screwed onto the bottom surfaces of the two first hydraulic telescopic outriggers.

[0008] Preferably, the hydraulically driven steering wheel is also equipped with a steering control motor, and the energy storage battery is electrically connected to the steering control motor.

[0009] Preferably, the following hydraulic telescopic transport frame includes symmetrically arranged second hydraulic telescopic legs, second transverse hydraulic telescopic beams, and directional wheels. The second transverse hydraulic telescopic beams are screwed between the telescopic ends of the two second hydraulic telescopic legs, and directional wheels are screwed onto the bottom surfaces of the two second hydraulic telescopic legs.

[0010] Through the above technical solutions, the hydraulically driven steering wheels and steering control motors on the first hydraulic telescopic outriggers enable the equipment to control its direction more flexibly and precisely when turning. Combined with the directional wheel design of the second hydraulic telescopic outriggers, it can stably follow the direction of travel of the steering transport frame during transportation. The fixed rolling direction of the directional wheels reduces lateral swaying during transportation, making the entire transport system smoother when traveling in a straight line, ensuring the safety and stability of cargo transportation. The first and second hydraulic telescopic outriggers, as well as the first and second transverse hydraulic telescopic beams, can be extended and adjusted according to actual transportation needs to adapt to the transportation of containers of different sizes. The hydraulic system enables the synchronous extension and retraction of the outriggers and transverse beams, as well as the steering of the wheels. Even operators without professional training can quickly get started, improving work efficiency.

[0011] Preferably, the telescopic ends of the first and second transverse hydraulic telescopic beams face the same direction, and the second transverse hydraulic telescopic beam is higher than the first transverse hydraulic telescopic beam.

[0012] Preferably, the fixed beam is C-shaped, and the mounting bracket is welded to the concave surface of the fixed beam, with the two concave surfaces of the fixed beam facing inwards towards each other.

[0013] Through the above technical solutions, the staggered layout of the second and first transverse hydraulic telescopic beams makes it easy to distinguish the front and rear installation positions of the container and facilitates the opening and closing of the container door; the C-shaped fixed beam provides a stable installation foundation for the mounting bracket and can withstand greater external forces.

[0014] In summary, this utility model has the following beneficial effects: 1. This utility model uses a steering hydraulic telescopic transport frame and a following hydraulic telescopic transport frame with a fixed beam, resulting in a stable structure with hydraulic telescopic function. It integrates lifting and moving functions, eliminating the need for equipment switching, making operation simple and requiring only one person to operate, significantly improving work efficiency. It is adaptable to containers of different specifications, solving the pain points of traditional simple tools with limited functions and poor adaptability. It also has low maintenance costs and does not require complex site conditions. Multiple mounting brackets provide mounting points for the equipment, providing reliable basic support for subsequent cargo transportation.

[0015] 2. Through the hydraulic drive steering wheel and steering control motor on the first hydraulic telescopic outrigger, the equipment can control its direction more flexibly and precisely when turning. In conjunction with the directional wheel design of the second hydraulic telescopic outrigger, it can stably follow the direction of travel of the steering transport frame during transportation. The directional wheel rolls in a fixed direction, reducing lateral sway during transportation, making the entire transportation system more stable when traveling in a straight line, and ensuring the safety and stability of cargo transportation.

[0016] 3. The first and second hydraulic telescopic outriggers and the first and second transverse hydraulic telescopic beams can be extended and adjusted according to actual transportation needs to adapt to the transportation of containers of different sizes. The hydraulic system enables the synchronous extension and retraction of the outriggers and transverse beams and the steering of the wheels. Even operators without professional training can quickly get started, improving work efficiency.

[0017] 4. The staggered layout of the second and first transverse hydraulic telescopic beams makes it easy to distinguish the front and rear installation positions of the container and facilitates the opening and closing of the container door; the C-shaped fixed beam provides a stable installation foundation for the mounting bracket and can withstand greater external forces.

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] A simple loading and unloading mobile device for container cargo, such as Figures 1-5 As shown, the system includes a steering hydraulic telescopic transport frame 1, a following hydraulic telescopic transport frame 2, and a fixed beam 5. The steering hydraulic telescopic transport frame 1 is fixedly connected to the following hydraulic telescopic transport frame 2 via the oppositely arranged fixed beam 5, forming a stable overall structure. A hydraulic pump station 3 and an energy storage battery 4 are located on the side of the steering hydraulic telescopic transport frame 1 away from the fixed beam 5. The hydraulic pump station 3 is connected to the steering hydraulic telescopic transport frame 1 and the following hydraulic telescopic transport frame 2 via oil pipes. The energy storage battery 4 is electrically connected to the steering hydraulic telescopic transport frame 1 and the hydraulic pump station 3. Mounting brackets 6 are fixedly installed on the inner sides of both ends of the fixed beam 5. The fixed beam 5 is screwed to the telescopic ends of the steering hydraulic telescopic transport frame 1 and the following hydraulic telescopic transport frame 2, and rises or falls as the steering hydraulic telescopic transport frame 1 and the following hydraulic telescopic transport frame 2 extend and retract, ensuring that the items mounted on the fixed beam 5 remain stable during transportation and avoiding safety issues such as tilting or slipping of items due to inconsistent height changes. The hydraulic pump station 3 provides hydraulic power to the two transport frames, while the energy storage battery 4 provides electrical support to the related equipment.

[0023] The hydraulic pump station 3 and the energy storage battery 4 also move synchronously with the extension and retraction of the steering hydraulic telescopic transport frame 1.

[0024] The fixed beam 5 is C-shaped, and the mounting bracket 6 is welded to the concave surface of the fixed beam 5. The concave surfaces of the two fixed beams 5 are set inwards and opposite to each other. The fixed beam 5 is made of Q355 steel (with a load capacity of 30-40 tons). There are four mounting brackets 6. The two fixed beams 5 are parallel and opposite to each other, and the four mounting brackets 6 correspond to each other. During operation, they correspond to the four corners of the container, hang the container, and weld it to ensure stable load-bearing capacity.

[0025] The steering hydraulic telescopic transport frame 1 includes symmetrically arranged first hydraulic telescopic legs 11, a first transverse hydraulic telescopic beam 12, and hydraulically driven steering wheels 13. The first transverse hydraulic telescopic beam 12 is screwed between the telescopic ends of the two first hydraulic telescopic legs 11. A hydraulic pump station 3 and an energy storage battery 4 are fixedly installed on the side of the first transverse hydraulic telescopic beam 12 away from the fixed beam 5. The bottom surfaces of the two first hydraulic telescopic legs 11 are screwed with hydraulically driven steering wheels 13. The hydraulic pump station 3 and the energy storage battery 4 are fixed in the middle of the non-telescopic end side of the first transverse hydraulic telescopic beam 12. One of the first hydraulic telescopic legs 11, which is closer to the energy storage battery 4, is screwed to the telescopic end face of the first transverse hydraulic telescopic beam 12, while the other is screwed to the non-telescopic end of the first transverse hydraulic telescopic beam 12. The first transverse hydraulic telescopic beam 12 connects the two legs into a whole, enhancing the structural strength and rigidity of the transport frame.

[0026] The hydraulically driven steering wheel 13 is also equipped with a steering control motor. The energy storage battery 4 is electrically connected to the steering control motor. The energy storage battery 4 supplies power to the hydraulic pump station 3 and the steering control motor. The hydraulically driven steering wheel 13 can flexibly steer. When the operator issues a steering command, the steering wheel automatically completes the steering action, which greatly reduces the labor intensity of the personnel and saves time and effort.

[0027] The following hydraulic telescopic transport frame 2 includes symmetrically arranged second hydraulic telescopic outriggers 21, second transverse hydraulic telescopic beams 22, and directional wheels 23. The second transverse hydraulic telescopic beams 22 are screwed between the telescopic ends of the two second hydraulic telescopic outriggers 21. The bottom surfaces of the two second hydraulic telescopic outriggers 21 are screwed with directional wheels 23. The following hydraulic telescopic transport frame 2 differs from the steering hydraulic telescopic transport frame 1 only in the directional wheels 23 and the hydraulically driven steering wheels 13. The following hydraulic telescopic transport frame 2 focuses on the stability and accuracy of linear movement and is used as a following or auxiliary transport device.

[0028] The steering hydraulic telescopic transport frame 1 and the following hydraulic telescopic transport frame 2 each form a relatively independent module. The hydraulic telescopic outriggers and the transverse hydraulic telescopic beams of the two transport frames are connected by bolts to form an I-shaped whole.

[0029] The telescopic ends of the first transverse hydraulic telescopic beam 12 and the second transverse hydraulic telescopic beam 22 face the same direction, ensuring that the two hydraulic telescopic beams can maintain coordinated movement during telescopic processes. The second transverse hydraulic telescopic beam 22 is higher than the first transverse hydraulic telescopic beam 12, and the height difference distinguishes the front and rear ends of the container. The higher second transverse hydraulic telescopic beam 22 provides sufficient space for the opening and closing of the door, allowing operators to easily complete the door operation without additional equipment height adjustments or complex operations.

[0030] The first hydraulic telescopic outrigger 11 and the second hydraulic telescopic outrigger 21 are preferably made of high-strength alloy, which balances strength and lightness. There are a total of four first hydraulic telescopic outriggers 11 and second hydraulic telescopic outriggers 21, which have the same shape and structure.

[0031] The hydraulic pump station 3 has a working pressure of 15-20MPa; the energy storage battery 4 is a 12V / 100Ah lead-acid battery, which can work continuously for 4-6 hours on a single charge; the hydraulically driven steering wheel 13 has a diameter of 200mm and is suitable for ordinary cement and gravel floors.

[0032] All parts and equipment use conventional models in the existing technology. In addition, the circuit and communication connections use conventional connection methods in the existing technology. The hydraulic pump station 3 and the energy storage battery 4 are connected to the external control cabinet for communication. The oil pipes are not shown in the figure. It is equipped with a manual control handle and integrates "lifting start / stop", "steering adjustment" and "movement start / stop" buttons. It is not considered as the technical problem to be solved or the object of protection of this utility model, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] Working principle: The operator pushes the equipment to the bottom of the container and adjusts the direction of the hydraulic drive steering wheel 13 by the steering control motor, so that the mounting bracket 6 fits against the bottom support point of the container. The directional wheel 23 assists in positioning to ensure that the equipment is aligned with the container. Start the hydraulic pump station 3 to supply hydraulic oil to the telescopic outriggers, drive the four telescopic outriggers to extend synchronously, lift the mounting bracket 6, and raise the container to lift it off the ground to complete the lifting action. If the width needs to be adjusted, the hydraulic pump station 3 supplies oil to the telescopic beams to drive the two telescopic beams to extend synchronously, thereby adjusting the width. After the container is lifted, the energy storage battery 4 supplies power to the hydraulic drive steering wheel 13, which makes the steering control motor run. The operator adjusts the direction through the steering control motor and pushes the equipment to move the container to the target position. The directional wheel 23 helps to maintain stability. Upon reaching the target location, the hydraulic pump station 3 is controlled to recover hydraulic oil, and the outriggers retract synchronously, slowly lowering the container to the ground or carrying platform. After stabilization, the equipment is pushed off the container to complete the loading and unloading process.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
