Abstract
Description
Technical Field
[0001] The utility model belongs to the field of liquid storage and transportation, and particularly relates to a folding pipeline lifting device and a liquid storage and transportation device. Background Art
[0002] In the field of liquid storage and transportation, especially in the process of liquid storage and transportation in large storage tanks, reactors, and industries widely involved in chemical engineering, petroleum, food, etc., liquid pumping and draining operations are essential links. The efficient execution of these operations is directly related to the smoothness of the production process, the control of product quality, and the maximization of resource utilization. In order to achieve effective liquid extraction and discharge, the pipeline system must be able to accurately and quickly extend below the liquid level to ensure the accuracy and efficiency of the operation.
[0003] However, most of the current liquid pumping and draining pipelines widely used are of fixed structures, and such designs have exposed many inconveniences and limitations in practical applications. First of all, after the fixed pipeline is installed, its position is determined, and it is difficult to flexibly adjust according to the different sizes of liquid storage containers and the changes in liquid levels. This rigid design not only limits the adaptability of the pipeline in various application scenarios but also may cause the pipeline to be unable to accurately reach below the liquid level under specific operating conditions, requiring an external extension pipe, thus affecting the pumping and draining efficiency.
[0004] Secondly, in some liquid pumping and draining scenarios, especially when the structure of the liquid storage equipment is complex or the space is limited, it is necessary to manually send the pipeline into the liquid storage equipment. This process not only increases the operation time but also raises the labor cost. In addition, manual operation may also cause errors due to human factors, affecting the operation accuracy and safety.
[0005] Furthermore, the low degree of automation of the fixed pipeline is also an important factor restricting its application effect. With the continuous development of industrial automation technology, the requirements for automation and intelligence in all aspects of the production process are getting higher and higher. Due to the design limitations of the fixed pipeline, it is difficult to effectively integrate with modern automated control systems, restricting the further improvement of production efficiency.

[0030] As Figure 1 shown, a folding pipeline lifting device includes a base 1. A telescopic mechanism 2 is provided on the upper part of the base 1. One end of the telescopic mechanism 2 is hinged to the side of a swing pipe 7. One end of the swing pipe 7 is rotatably connected to one end of a lifting pipe 8. Through the control of the telescopic mechanism 2, the folding swing of the swing pipe 7 is realized, and the swing pipe 7 drives the lifting pipe 8 to lift and lower, adapting to liquid storage containers of different heights and depths, enhancing the versatility and flexibility of liquid pumping and drainage. In addition, in the non-working state, after the lifting pipe 8 is reset, the space occupied by the lifting pipe 8 is reduced.
[0031] As Figure 1 、 Figure 2 shown, a swing arm 3 is hinged to the end of the base 1. One end of the telescopic mechanism 2 is hinged to the side wall of the swing arm 3. One end of the swing arm 3 is connected to a lifting pipe 8. One end of the lifting pipe 8 is rotatably connected to a swing pipe 7.
[0032] As Figure 2 shown, a third hinge support 11 is provided on the upper part of the base 1. The lower end of the telescopic mechanism 2 is hinged to the third hinge support 11.
[0033] The telescopic mechanism 2 includes, but is not limited to, a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, an electric push rod or a rigid chain. As Figure 2 shown, in this embodiment, the telescopic mechanism adopts a servo electric cylinder.
[0034] As Figure 1 、 Figure 2As shown in the figure, a bushing (not shown in the figure) that penetrates through the swing arm 3 is provided at each end of the swing arm 3. Among them, a first bearing seat 4 is rotatably connected to the outside of the lower bushing. One end of the first bearing seat 4 is fixedly connected to the base 1. The swing pipe 7 includes a U-shaped pipe 71. The lower end of the U-shaped pipe 71 is connected to a connecting pipe 73 through a rotary joint 72. The connecting pipe 73 is installed in the bushing at the lower end of the swing arm 3. The upper end of the U-shaped pipe 71 is connected to the lifting pipe 8 through a rotary joint 72. The lifting pipe 8 is installed in the bushing at the upper end of the swing arm 3. When the swing arm 3 swings, the lifting pipe 8 remains in a vertical state, ensuring the posture of the lifting pipe 8 when pumping and discharging liquid.
[0035] As a possible implementation form, in order to ensure the stability of the lifting pipe 8 during the lifting process, a link mechanism is provided as follows. A first hinge support 9 is fixedly connected to the upper part of the first bearing seat 4. A second bearing seat 5 is rotatably connected to the outside of the upper bushing. A second hinge support 10 is hinged to the upper part of the second bearing seat 5. A link 6 is provided between the first hinge support 9 and the second hinge support 10, and the link 6 is arranged in parallel with the swing arm 3. The link 6, the first hinge support 9, the swing arm 3, and the second hinge support 10 form a parallelogram four-bar linkage. When the swing arm 3 swings, the lifting pipe 8 remains in a vertical state in the parallelogram four-bar linkage formed by the link 6, the first hinge support 9, the swing arm 3, and the second hinge support 10, ensuring the posture of the lifting pipe 8 when pumping and discharging liquid.
[0036] As another possible implementation method, as Figure 3 shown, there is no need to set the swing arm 3. The telescopic mechanism 2 is directly connected to the side of the swing pipe 7.

[0038] As Figure 4 shown, an AGV chassis is provided at the lower part of the mother vehicle 12. The AGV chassis cooperates with the folding pipeline lifting device to realize the automated operation of the liquid storage and transportation operation, further reducing the labor intensity of the operators and improving the efficiency of the liquid storage and transportation operation.
[0039] Preferably, there are two folding pipeline lifting devices, which are respectively arranged on both sides of the mother vehicle 12. Valves are provided on the connecting pipes 73 of the folding pipeline lifting devices on both sides. The bilateral arrangement enables the mother vehicle 12 to perform liquid storage and retrieval operations from both sides simultaneously, greatly improving the operation efficiency. Especially in the case of handling a large amount of liquid or requiring rapid turnover, this design can significantly shorten the operation time. In addition, the bilateral arrangement also increases the operation flexibility. When one side of the device needs to be suspended for maintenance or due to a fault, the device on the other side can still continue to work, ensuring that the production process is not affected.
[0040] As a possible implementation method, to prevent residual liquid from dripping onto the ground or equipment from the nozzle of the lifting pipe 8 after the storage or retrieval operation is completed, a liquid collecting device (not shown in the figure) is provided at the lower part of the mother vehicle 12 (at the position of the lifting pipe 8) for collecting the residual liquid at the nozzle of the lifting pipe 8 when the lifting pipe 8 is in the retracted state. For example, the liquid collecting device can be a tray provided with a telescopic device, which extends out after the lifting pipe 8 is retracted to receive the residual liquid dripping from the nozzle.
