Description

Technical Field

[0001] The present invention relates to the technical field of conveying devices, and particularly to a conveying device for a tank container body. Background Art

[0002] Currently, in the tank container production industry, the tank container body usually needs to be transferred from the production line to the general assembly production line for assembly. In the prior art, the transportation of the tank body mostly adopts the method of hoisting by a traveling crane. The operator needs to pass a lifting rope through the support structure of the tank body, and then the traveling crane lifts and transfers the tank body to the designated position. This transportation method is not only time-consuming and laborious, but also has the following problems:

[0003] First, the process of threading the lifting rope is cumbersome, and the operator needs to repeatedly adjust the position, wasting a lot of time. The hoisting process depends on manual operation, resulting in low overall work efficiency and difficult to meet the requirements of modern production lines.

[0004] Second, during the hoisting process, the tank body is suspended in the air, there is a risk of shaking, and it is easy to deviate or tilt, increasing the work difficulty and safety risk of the operator. If the tank body shakes or collides during the hoisting process, it may cause damage to the equipment and the product itself, and there are relatively large potential safety hazards.

[0005] Third, since the tank body is prone to bumps during lifting and placing, the outer surface of the tank body may be damaged, which will affect the final quality of the product. At the same time, it is difficult to control the precise position of the tank body by the traveling crane hoisting method, which may lead to instability of the tank body during transportation and affect the subsequent assembly efficiency. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems in the background art, and a conveying device for a tank container body is proposed.

[0007] To achieve the above purpose, the present invention adopts the following technical solution: A conveying device for a tank container body, comprising:

[0008] A ground rail;

[0009] A mobile lifting vehicle, arranged on the ground rail and moving along the ground rail;

[0010] A saddle, arranged on the mobile lifting vehicle for supporting the tank container body. The saddle is installed on the mobile lifting vehicle and rotates to a predetermined angle during use. An arc-shaped groove adapted to the tank container body is provided on the saddle, and a clamping groove is provided on the side surface of the saddle;

[0011] A lifting mechanism, installed on the mobile lifting vehicle for driving the saddle to lift, so that the tank container body can be disengaged from the production line support;

[0012] The locking mechanism is arranged on the saddle and is used to lock the saddle in a fixed position after the saddle rotates to a predetermined angle, ensuring the stability of the tank container during transportation.

[0013] Preferably, the mobile lifting vehicle includes an upper platform and a lower platform connected by a lifting mechanism.

[0014] Preferably, the upper platform includes channel steels arranged in a mu shape and rectangular steels connected to the inner side walls of the channel steels;

[0015] Two groups of saddle flipping mechanisms are symmetrically arranged on the rectangular steel;

[0016] The saddle flipping mechanism includes a flipping support A installed on the rectangular steel and a flipping support B fixed on the saddle. The flipping support A and the flipping support B are connected by a shaft. A cylinder connection support is also connected to the channel steel. A cylinder is rotatably connected to the cylinder connection support. An articulated seat rotatably connected to the output end of the cylinder is arranged on the saddle. The cylinder is used to drive the flipping of the saddle;

[0017] A connecting shaft sleeve and a fixed shaft are slidably arranged on the side surface of the channel steel.

[0018] Preferably, the lower platform includes a rectangular steel frame. U-shaped steel a and U-shaped steel b are vertically arranged inside the rectangular steel frame, and U-shaped steel a and U-shaped steel b are fixedly connected perpendicular to each other. Rollers are installed below the rectangular steel frame. The rollers are used to move the conveying device on the ground rail;

[0019] A first mounting seat and a second mounting seat are arranged on the side surface of U-shaped steel a. Mounting bushings are symmetrically and slidably arranged on U-shaped steel b. The mounting bushings, the first mounting seat, and the second mounting seat are used to connect the lower platform to the lifting mechanism.

[0020] Preferably, the lifting mechanism includes two first rectangular tubes and second rectangular tubes arranged in a cross shape. The first rectangular tubes and the second rectangular tubes are connected to each other by a connecting shaft. A third rectangular tube is connected between the two first rectangular tubes;

[0021] An oil cylinder connection support installed on the connecting shaft is further included. An oil cylinder is connected to the oil cylinder connection support;

[0022] One end of the first rectangular tube is rotatably connected to the first mounting seat by a shaft, and one end of the second rectangular tube is rotatably connected to the mounting bushing by a shaft;

[0023] The tail end of the oil cylinder is connected to the second mounting seat by a shaft;

[0024] The other end of the first rectangular tube is rotatably connected to the connecting shaft sleeve by a shaft, and the other end of the second rectangular tube is connected to the channel steel by a fixed shaft.

[0025] Preferably, the lower surface of the rectangular steel on the upper platform protrudes from the lower surface of the channel steel. An avoidance groove is formed in the rectangular steel frame of the lower platform, so that when the rectangular steel on the upper platform moves downward, it falls into the avoidance groove, realizing the fitting of the upper and lower platforms, reducing the height of the mobile lifting vehicle, and preventing collision with the bottom of the tank container body when the empty vehicle is traveling.

[0026] Preferably, the locking mechanism includes an arc-shaped embedding groove formed in the saddle and matching with the arc-shaped groove. A guide hole is communicated with the arc-shaped embedding groove. A spring groove is communicated with the arc-shaped embedding groove at the position of the guide hole. A guide rod is slidably connected in the guide hole. One end of the guide rod is connected with an arc-shaped pressing plate matching with the arc-shaped embedding groove. The other end of the guide rod is connected with a pressing rod through a connecting rod. A first spring is sleeved on the guide rod. One end of the first spring abuts against the lower surface of the arc-shaped pressing plate, and the other end of the first spring abuts against the inner bottom of the spring groove.

[0027] A fixing plate is connected between the two rectangular steels. A positioning hole matching with the pressing rod is formed in the fixing plate, and the positioning hole is arranged in a funnel shape.

[0028] When the tank container body is placed on the arc-shaped pressing plate, the arc-shaped pressing plate is extruded and moves downward. The arc-shaped pressing plate is embedded into the arc-shaped embedding groove, and at the same time drives the guide rod and the pressing rod to move, so that the pressing rod is inserted into the positioning hole, realizing the positioning and locking of the saddle.

[0029] A block matching with the card slot is also fixedly connected to the channel steel, so as to ensure that the saddle is set at 90° after being flipped.

[0030] Preferably, a locking component for locking the lifting mechanism is fixedly connected to the lower side of the fixing plate.

[0031] The locking component includes a fixed shell connected below the fixing plate. A strip-shaped hole is formed in the side surface of the fixed shell. A locking dial is rotatably installed inside the fixed shell. The locking dial movably penetrates through the strip-shaped hole. A plurality of convex blocks are arranged at intervals on the side surface of the second rectangular pipe. When the second rectangular pipe rotates, it is stuck at the convex blocks to lock the first rectangular pipe and the second rectangular pipe, preventing the lifting mechanism from being unstable during transportation.

[0032] Preferably, a wedge block is arranged on the side surface of the locking dial. A second spring is fixedly connected to the lower end of the pressing rod. The other end of the second spring is fixedly connected to a tapered block arranged in a tapered shape. The inclined surface of the tapered block is matched with the inclined surface of the wedge block.

[0033] Preferably, an electromagnet is installed on the opposite side surface of the fixed shell to the strip-shaped hole, and the electromagnet is used to control the swing of the locking dial.

[0034] Compared with the existing technology, the advantages of the tank container conveying device are:

[0035] 1. The tank container body conveying device of the present invention realizes double safety protection through the locking mechanism and the locking assembly. The combination of the arc-shaped pressure plate, the guide rod and the pressure rod in the locking mechanism ensures that the tank container body is firmly fixed on the saddle; and the clamping design of the locking paddle and the protrusion in the locking assembly further locks the position of the lifting mechanism. The double locking mechanism significantly improves the safety and stability during transportation, effectively prevents the tank container body from shaking or tilting during transportation, and greatly reduces the risk of safety accidents.

[0036] 2. During the unloading process of the present invention, the controller first activates the electromagnet to overcome the elastic force of the second spring and automatically releases the lock of the locking assembly; then the oil cylinder is controlled to achieve a smooth descent, which not only greatly improves the operating efficiency and reduces the need for manual intervention, but also ensures the stability and safety of the unloading process through precise control. The tank body is safely and reliably transported from the front to the back station through the automatic lifting transport vehicle, which reduces the labor of the operators during the operation and improves the operating efficiency and product quality of the tank transportation.

Detailed implementation manners

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0051] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. Embodiment

[0052] In the tank container production industry, the transfer of the tank container body from the production line to the general assembly production line is a key link, directly affecting production efficiency and product quality. In the prior art, the transportation of the tank body mostly adopts the method of hoisting by a traveling crane. This method requires the operator to pass a lifting rope through the support structure of the tank body, and then the traveling crane lifts and transfers the tank body to the designated position.

[0053] However, the hoisting method by a traveling crane has some significant disadvantages: the operator needs to work at height, there is a risk of falling. At the same time, the tank body may swing during the hoisting process, increasing the risks of collision and falling. Each hoisting requires manual threading, fixing and untying of the rope, which takes a long time and affects production efficiency.

[0054] To solve the above problems, the present application provides a tank container body conveying device, referring to Figures 1 - 4 , including: a ground rail 100;

[0055] A mobile lifting vehicle 200, the ground rail 100 is installed on the ground of the production workshop, providing a traveling path for the mobile lifting vehicle 200. The ground rail 100 can adopt a standard track to ensure the smooth movement of the mobile lifting vehicle 200. The mobile lifting vehicle 200 can be driven by an electric motor. The mobile lifting vehicle 200 includes an upper platform 210 and a lower platform 220;

[0056] A saddle 300, arranged on the upper platform 210 of the mobile lifting vehicle 200, for supporting the tank container body 400. The saddle 300 is installed on the mobile lifting vehicle 200 and rotates to a predetermined angle during use. An arc-shaped groove 301 adapted to the tank container body 400 is provided on the saddle 300 to ensure the stable placement of the tank body. A clamping groove 302 is provided on the side of the saddle 300;

[0057] A lifting mechanism 500, installed on the mobile lifting vehicle 200, for driving the saddle 300 to lift, so that the tank container body 400 can be separated from the production line support, avoiding the risks of the traditional hoisting method. The lifting mechanism 500 is a scissor type and adopts a hydraulic or electric drive lifting method to ensure the smoothness and accuracy of the lifting process. In this embodiment, a hydraulic method is specifically adopted for driving;

[0058] A locking mechanism 600, arranged on the saddle 300, for locking the saddle 300 in a fixed position after the saddle 300 rotates to a predetermined angle, ensuring the stability of the tank container body 400 during transportation and preventing accidental movement or tilting.

[0059] During use, the mobile lifting vehicle 200 moves along the ground rail 100 to the position below the tank container body 400 to be transported. Through the saddle flipping mechanism 213, the saddle 300 is rotated 90° from the upper platform 210 of the mobile lifting vehicle 200 to the position required for jacking, so that the saddle 300 can be docked with the tank container body 400. The lifting mechanism 500 drives the upper platform 210 and the saddle 300 to rise. The arc-shaped groove 301 on the saddle 300 fits with the bottom of the tank container body 400, and continues to rise until the tank container body 400 is completely separated from the production line support. This process is stable and safe, avoiding the shaking risk of the traditional lifting method. When the tank container body 400 contacts the saddle 300, the locking mechanism 600 is randomly activated to firmly lock the saddle 300 in the current position (vertically set) to ensure stability during transportation. Subsequently, the mobile lifting vehicle 200 transports the tank container body 400 along the ground rail 100 to the rotating platform at the pre-loading station of the general assembly line. After reaching the target position, the lifting mechanism 500 controls the upper platform 210 and the saddle 300 to descend, so that the tank container body 400 is smoothly placed on the tank support on the rotating platform, ensuring the safe placement of the tank body. After the unloading of the tank container body 400 is completed, the mobile lifting vehicle 200 retracts the saddle 300 to prepare for the next transportation task, which not only significantly improves the production efficiency of the tank container body 400, reduces the safety risk, but also optimizes the production process, bringing significant economic and social benefits to the production enterprises of the tank container body 400. Embodiment

[0060] This embodiment is implemented on the basis of the above embodiment, and further details the structure of the mobile lifting vehicle 200, especially the specific implementation methods of the saddle flipping mechanism 213 and the lifting mechanism 500. Refer to Figures 5 - 8 , wherein, the mobile lifting vehicle 200 includes an upper platform 210 and a lower platform 220 connected by a lifting mechanism 500.

[0061] The upper platform 210 includes channel steels 211 arranged in a rectangular shape and rectangular steels 212 connected to the inner side walls of the channel steels 211, enhancing the structural strength of the upper platform 210;

[0062] Two groups of saddle flipping mechanisms 213 are symmetrically arranged on the rectangular steel 212;

[0063] The saddle flipping mechanism 213 includes a flipping support A214 installed on the rectangular steel 212 and a flipping support B215 fixed on the saddle 300. The flipping support A214 and the flipping support B215 are connected by an axis, which ensures the balance of the saddle 300 during the flipping process and reduces shaking and instability. The channel steel 211 is also connected to a cylinder connecting support 216, and a cylinder 217 is rotatably connected to the cylinder connecting support 216. The saddle 300 is provided with an articulated seat 218 rotatably connected to the output end of the cylinder 217. The cylinder 217 is used to drive the flipping of the saddle 300. The setting of the cylinder 217 makes the flipping action of the saddle 300 more stable and controllable. By adjusting the telescopic speed and stroke of the cylinder 217, the flipping angle and speed of the saddle 300 can be accurately controlled to meet the needs of different types of tanks.

[0064] A connecting sleeve 219 and a fixed shaft are also slidably provided on the side of the channel steel 211 .

[0065] The lower platform 220 includes a rectangular steel frame 221, and a U-shaped steel a222 and a U-shaped steel b223 are vertically arranged on the inner side of the rectangular steel frame 221, and the U-shaped steel a222 and the U-shaped steel b223 are vertically fixedly connected to each other. A roller 224 is installed below the rectangular steel frame 221, and the roller 224 is used to move the conveying device on the ground rail 100. The cross design of the U-shaped steel a222 and the U-shaped steel b223 enhances the torsion resistance of the lower platform 220, ensuring that it remains stable during movement and load-bearing. The design of the roller 224 enables the entire device to move smoothly on the ground rail 100;

[0066] A first mounting seat 225 and a second mounting seat 226 are provided on the side of the U-shaped steel a222, and a mounting sleeve 227 is symmetrically slidably provided on the U-shaped steel b223. ​​The mounting sleeve 227, the first mounting seat 225 and the second mounting seat 226 are used to connect the lower platform 220 with the lifting mechanism 500.

[0067] The lifting mechanism 500 includes two first rectangular tubes 501 and a second rectangular tube 502 arranged in a cross-like manner. The first rectangular tube 501 and the second rectangular tube 502 are connected to each other via a connecting shaft 503. A third rectangular tube 504 is connected between the two first rectangular tubes 501.

[0068] It also includes a cylinder connection support 505 installed on the connection shaft 503, and the cylinder connection support 505 is connected to the cylinder 506;

[0069] One end of the first rectangular tube 501 is rotatably connected to the first mounting seat 225 through an axis, and one end of the second rectangular tube 502 is rotatably connected to the mounting sleeve 227 through an axis;

[0070] The tail end of the oil cylinder 506 is connected to the second mounting seat 226 via a shaft;

[0071] The other end of the first rectangular tube 501 is rotationally connected to the connecting shaft sleeve 219 through a shaft, and the other end of the second rectangular tube 502 is connected to the channel steel 211 through a fixed shaft.

[0072] The lower surface of the rectangular steel 212 of the upper platform 210 protrudes from the lower surface of the channel steel 211. An avoidance groove 228 is provided on the rectangular steel frame 221 of the lower platform 220, so that when the rectangular steel 212 of the upper platform 210 moves downward, it falls into the avoidance groove 228, realizing the fitting of the upper and lower platforms, reducing the height of the mobile lifting vehicle 200, and preventing collision with the bottom of the tank container 400 when the empty vehicle is moving forward.

[0073] During use, when the oil cylinder 506 extends, it pushes the first rectangular tube 501 and the second rectangular tube 502 to move relative to each other, causing the cross structure to unfold, thereby realizing the rise of the upper platform 210; when the oil cylinder 506 contracts, it realizes the descent.

[0074] The lower surface of the rectangular steel 212 of the upper platform 210 protrudes from the lower surface of the channel steel 211, and an avoidance groove 228 is provided on the rectangular steel frame 221 of the lower platform 220. When not in use, the upper platform 210 can be embedded deeper into the lower platform 220, reducing the minimum height of the device. The closer fitting of the upper and lower platforms increases the overall stability and reduces the risk of collision with the bottom of the tank container 400 when the empty vehicle is moving forward.

[0075] Saddle 300 flipping process: Operate the cylinder 217 to drive the saddle 300 to rotate around the connecting shaft of the flipping support A214 and the flipping support B215 to achieve a 90-degree flip. By controlling the telescopic movement of the oil cylinder 506, the lifting of the upper platform 210 is realized, and the saddle 300 is adjusted to an appropriate height. Then, the tank container 400 is safely placed on the saddle 300. During this process, the locking mechanism 600 is started synchronously to ensure the stability of the tank container 400 during transportation. Through the rollers 224, the tank container 400 is transported along the ground rail 100 to the target position. Embodiment

[0076] In order to keep the saddle 300 in a stable posture, in this embodiment, based on the above embodiment, the design and working principle of the locking mechanism 600 are mainly elaborated, aiming to ensure the stability and safety of the tank container 400 during transportation. Refer to Figure 5 and Figure 6, the locking mechanism 600 includes an arc-shaped embedding groove 601 formed on the saddle 300 and matching with the arc-shaped groove 301. A guide hole 602 is communicated with the arc-shaped embedding groove 601. A spring groove 603 is communicated with the arc-shaped embedding groove 601 at the position of the guide hole 602. A guide rod 604 is slidably connected in the guide hole 602. One end of the guide rod 604 is connected with an arc-shaped pressing plate 605 matching with the arc-shaped embedding groove 601, ensuring uniform distribution of pressure. The design of the guide rod 604 ensures the vertical movement of the arc-shaped pressing plate 605, avoiding inclination and jamming. The other end of the guide rod 604 is connected with a pressing rod 606 through a connecting rod. A first spring 607 is sleeved on the guide rod 604. One end of the first spring 607 abuts against the lower surface of the arc-shaped pressing plate 605, and the other end of the first spring 607 abuts against the inner bottom of the spring groove 603;

[0077] A fixing plate 608 is connected between two rectangular steels 212. A positioning hole 609 matching with the pressing rod 606 is formed on the fixing plate 608. The positioning hole 609 is arranged in a funnel shape. The funnel-shaped design of the positioning hole 609 not only increases the error tolerance rate;

[0078] When the tank container body 400 is placed on the arc-shaped pressing plate 605, the arc-shaped pressing plate 605 is extruded and moves downward. The arc-shaped pressing plate 605 is embedded into the arc-shaped embedding groove 601, and at the same time drives the guide rod 604 and the pressing rod 606 to move, so that the pressing rod 606 is inserted into the positioning hole 609 to realize the positioning and locking of the saddle 300;

[0079] A block 610 matching with the clamping groove 302 is also fixedly connected to the channel steel 211. After the saddle 300 is turned over, it abuts against the block 610 to ensure that the saddle 300 is vertically arranged at 90°;

[0080] In the initial state, without load, the first spring 607 is in a natural state. The arc-shaped pressing plate 605 is located at the uppermost position of the arc-shaped embedding groove 601, and the pressing rod 606 is not inserted into the positioning hole 609;

[0081] When the tank body 400 is placed on the saddle 300, its weight is pressed on the arc-shaped pressing plate 605. In this process: the arc-shaped pressing plate 605 is pressed down by the weight of the tank body 400 and gradually embedded in the arc-shaped embedded groove 601. The downward movement of the arc-shaped pressing plate 605 drives the guide rod 604 to slide downward. The guide rod 604 drives the pressure rod 606 to move toward the fixed plate 608 through the connecting rod. The first spring 607 is compressed to store elastic potential energy. When the pressure is large enough, the arc-shaped pressing plate 605 is completely embedded in the arc-shaped embedded groove 601 and forms a tight fit with the bottom of the tank body 400. The pressure rod 606 Insert the positioning hole 609 to lock the saddle 300, and insert the pressure rod 606 into the positioning hole 609 to prevent the saddle 300 from shaking or flipping significantly, thereby improving the stability of the saddle 300. When the tank container body 400 needs to be unloaded, as the tank container body 400 is removed, the arc pressure plate 605 moves upward under the action of the first spring 607, and the pressure rod 606 withdraws from the positioning hole 609, releasing the locking state, and the system returns to the initial state to prepare for the next loading and transportation. Example

[0082] In order to further improve the stability of the conveying device, the lifting mechanism 500 needs to be locked. Figures 9 - 12 , a locking assembly 700 for locking the lifting mechanism 500 is fixedly connected to the lower side of the fixing plate 608;

[0083] The locking assembly 700 includes a fixed shell 701 connected to the bottom of the fixed plate 608, and a strip hole 702 is opened on the side of the fixed shell 701. A locking paddle 703 is rotatably installed inside the fixed shell 701, and the locking paddle 703 can move through the strip hole 702. A plurality of spaced protrusions 704 are arranged on the side of the second rectangular tube 502. When the second rectangular tube 502 rotates, it is stuck at the protrusion 704 to lock the first rectangular tube 501 and the second rectangular tube 502 to prevent the lifting mechanism 500 from being unstable during transportation.

[0084] A wedge block 705 is provided on the side of the locking paddle 703 , a second spring 706 is fixedly connected to the lower end of the pressure rod 606 , and a conical block 707 arranged in a cone shape is fixedly connected to the other end of the second spring 706 , and the inclined surface of the conical block 707 matches the inclined surface of the wedge block 705 .

[0085] An electromagnet 708 is installed on the opposite side of the fixed shell 701 to the strip hole 702. When the tank container body 400 is transported, the lifting mechanism 500 needs to be lowered and reset. The electromagnet 708 is connected to the controller of the oil cylinder 506. When the controller is pressed to reset the oil cylinder 506, the controller first controls the electromagnet 708 to attract the locking paddle 703 away from one end of the protrusion 704. A magnetic block is provided at one end of the locking paddle 703 away from the protrusion 704. The suction force of the electromagnet 708 overcomes the elastic force of the second spring 706, so that the locking paddle 703 moves out of the protrusion 704 and the lock is released.

[0086] Working process of the locking assembly 700: This process is closely related to the operation of the locking mechanism 600 of the third embodiment described above;

[0087] When not in operation, the arc pressure plate 605 is not pressed down, the pressure rod 606 is not inserted into the positioning hole 609, the locking paddle 703 and the protrusion 704 are not stuck, the second spring 706 is in a natural state, the tank body 400 is placed on the saddle 300, the arc pressure plate 605 is pressed down, the pressure rod 606 starts to move downward, the pressure rod 606 is completely inserted into the positioning hole 609, and the saddle 300 is locked. At the same time, the downward movement of the pressure rod 606 drives the second spring 706 and the conical block 707 to move downward, and the inclined position of the conical block 707 The surface contacts the wedge block 705, generating a horizontal thrust, and the locking paddle 703 swings and engages with the nearest protrusion 704, so that the locking paddle 703 is stuck at the protrusion 704, and the second spring 706 remains in a compressed state to ensure continuous contact between the locking paddle 703 and the protrusion 704. When the lifting mechanism 500 rises to a predetermined height, the locking paddle 703 automatically engages with the nearest protrusion 704 under the action of the second spring 706. This self-locking design ensures that the locked state will not be accidentally released even under vibration conditions.

[0088] When it is necessary to unload the tank container body 400, the upper platform 210 needs to be moved downward. At this time, a signal needs to be sent through the controller to activate the electromagnet 708. The electromagnet 708 generates suction to overcome the elastic force of the second spring 706, and the locking paddle 703 disengages from the protrusion 704, releasing the lock on the lifting mechanism 500. Then the controller controls the oil cylinder 506 to slowly contract, driving the lifting mechanism 500 to descend. In the early stage of descent, the saddle 300 continues to maintain its angle. After the tank container body 400 is disengaged from the arc pressure plate 605, the arc pressure plate 605 slowly rises, and the pressure rod 606 withdraws from the positioning hole 609, and the saddle 300 is driven to flip through the cylinder 217 and return to the initial position to prepare for the next transportation. The locking mechanism 600 and the locking assembly 700 not only play their respective roles, but also form a coordinated work as a whole, which greatly improves the safety, efficiency and reliability of tank transportation.
