Description

Technical Field

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

[0002] At present, in the tank container production industry, the tank container body usually needs to be transferred from the production line to the final assembly line for assembly. In the existing technology, the tank body is mostly transported by crane. Crane lifting requires operators to pass the lifting rope through the tank body's support structure, and then the crane lifts the tank body and transfers it to the designated location. This transportation method is not only time-consuming and labor-intensive, but also has the following problems: First, the process of threading the lifting rope is cumbersome, requiring the operator to repeatedly adjust the position, wasting a lot of time. The lifting process relies on manual operation, resulting in low overall work efficiency and difficulty in meeting the needs of modern production lines.

[0003] Second, during the lifting process, the tank body is suspended in the air, which poses a risk of shaking and is prone to displacement or tilting, increasing the operator's work difficulty and safety risks. If the tank body shakes or collides during the lifting process, it may cause damage to the equipment and the product itself, posing a major safety hazard.

[0004] Third, since the tank is prone to bumps during lifting and placement, the outer surface of the tank may be damaged, which in turn affects the final quality of the product. At the same time, the crane lifting method makes it difficult to control the precise position of the tank, which may cause instability in the tank during transportation and affect the subsequent assembly efficiency.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are 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 cannot be understood as a limitation on the present invention. Example

[0033] In the tank container production industry, the transfer of tank container bodies from the production line to the final assembly line is a key link that directly affects production efficiency and product quality. In the existing technology, the tank bodies are mostly transported by crane. This method requires operators to pass the lifting rope through the tank body's support structure, and then the crane will lift the tank body and transfer it to the designated location.

[0034] However, the crane-lifting method has some significant disadvantages: the operator needs to work at high altitude, which poses a risk of falling. At the same time, the tank may swing during the lifting process, increasing the risk of collision and falling. Each lifting operation requires manual rope threading, fixing and untying, which takes a long time and affects production efficiency.

[0035] In order to solve the above problems, the present application provides a tank container conveying device, referring to Figure 1-Figure 4 , including: ground rail 100; The mobile lift 200 and the ground rail 100 are installed on the floor of the production workshop to provide a travel path for the mobile lift 200. The ground rail 100 can adopt a standard track to ensure the smooth movement of the mobile lift 200. The mobile lift 200 can be driven by a motor. The mobile lift 200 includes an upper platform 210 and a lower platform 220; The saddle 300 is arranged on the upper platform 210 of the mobile lifting vehicle 200 and is used to support the tank body 400. The saddle 300 is installed on the mobile lifting vehicle 200 and rotated to a predetermined angle when in use. The saddle 300 is provided with an arc groove 301 adapted to the tank body 400 to ensure that the tank body is placed firmly. The side of the saddle 300 is provided with a clamping groove 302; The lifting mechanism 500 is installed on the mobile lifting vehicle 200 and is used to drive the saddle 300 to lift and lower so that the tank container body 400 can be separated from the production line support, thereby avoiding the risks of the traditional lifting method. The lifting mechanism 500 is a scissor type and adopts a hydraulic or electric driving lifting method to ensure the stability and accuracy of the lifting process. In this embodiment, a hydraulic driving method is specifically adopted; The locking mechanism 600 is disposed on the saddle 300 and is used to lock the saddle 300 in a fixed position after the saddle 300 rotates to a predetermined angle, thereby ensuring the stability of the tank container body 400 during transportation and preventing accidental movement or tilting.

[0036] When in use, the mobile lifting vehicle 200 moves along the ground rail 100 to the bottom of the tank container body 400 to be transported, and the saddle 300 is rotated 90° from the upper platform 210 of the mobile lifting vehicle 200 through the saddle flipping mechanism 213, so that it is in the position required for jacking, so that the saddle 300 can be docked with the tank container body 400, and the lifting mechanism 500 drives the upper platform 210 and the saddle 300 to rise, and the arc 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 bracket. This process is smooth and safe, and avoids the shaking risk of traditional lifting methods. When the tank body 400 contacts the saddle 300, the locking mechanism 600 is randomly started to firmly lock the saddle 300 in the current position (vertically set) to ensure stability during transportation. Then the mobile lifting vehicle 200 transports the tank body 400 along the ground rail 100 to the rotating platform of the pre-online 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 body 400 falls smoothly on the tank body support seat on the rotating platform to ensure that the tank body is safely in place. After the tank body 400 is unloaded, 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 body 400 and reduces safety risks, but also optimizes the production process, bringing significant economic and social benefits to the tank body 400 production enterprise. Example

[0037] This embodiment is implemented on the basis of the above embodiment, and further describes in detail the structure of the mobile lifting vehicle 200, especially the specific implementation of the saddle flip mechanism 213 and the lifting mechanism 500, referring to Figure 5-Figure 8 , wherein the mobile lifting vehicle 200 includes an upper platform 210 and a lower platform 220 connected by a lifting mechanism 500.

[0038] The upper platform 210 includes a channel steel 211 arranged in a mesh shape and a rectangular steel 212 connected to the inner wall of the channel steel 211, which enhances the structural strength of the upper platform 210; Two sets of saddle turning mechanisms 213 are symmetrically arranged on the rectangular steel 212; 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. A connecting sleeve 219 and a fixed shaft are also slidably provided on the side of the channel steel 211 .

[0039] 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; 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.

[0040] 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. 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; 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; The tail end of the oil cylinder 506 is connected to the second mounting seat 226 via a shaft; The other end of the first rectangular tube 501 is rotatably connected to the connecting sleeve 219 via an axis, and the other end of the second rectangular tube 502 is connected to the channel steel 211 via a fixed axis.

[0041] 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 opened on the rectangular steel frame 221 of the lower platform 220, so that the rectangular steel 212 of the upper platform 210 falls into the avoidance groove 228 when moving downward, thereby achieving the fit between the upper and lower platforms, reducing the height of the mobile lifting vehicle 200, and preventing the empty vehicle from colliding with the bottom of the tank container body 400 when traveling.

[0042] When in use, when the oil cylinder 506 is extended, it pushes the first rectangular tube 501 and the second rectangular tube 502 to move relative to each other, so that the cross structure is unfolded, thereby realizing the rise of the upper platform 210; when the oil cylinder 506 is retracted, it realizes the descent; The lower surface of the rectangular steel 212 of the upper platform 210 protrudes from the lower surface of the channel steel 211, and the rectangular steel frame 221 of the lower platform 220 is provided with an avoidance groove 228. When not in use, the upper platform 210 can be more deeply embedded in the lower platform 220, reducing the minimum height of the device. The tighter fit between the upper and lower platforms increases the overall stability and reduces the risk of collision with the bottom of the tank container body 400 when the empty vehicle is traveling.

[0043] The flipping process of the saddle 300: the operating cylinder 217 drives the saddle 300 to rotate around the connecting axis of the flip support A214 and the flip support B215 to achieve a 90-degree flip. By controlling the extension and retraction of the oil cylinder 506, the upper platform 210 is lifted and lowered, and the saddle 300 is adjusted to a suitable height. Then, the tank container body 400 is safely placed on the saddle 300. During this process, the locking mechanism 600 is synchronously started to ensure the stability of the tank container body 400 during transportation. The tank container body 400 is transported to the target position along the ground rail 100 through the roller 224. Example

[0044] In order to keep the saddle 300 in a stable posture, this embodiment is based on the above embodiment, focusing on the design and working principle of the locking mechanism 600, aiming to ensure the stability and safety of the tank body 400 during transportation. Figure 5 and Figure 6The locking mechanism 600 includes an arc-shaped embedded groove 601 provided on the saddle 300 and matching the arc-shaped groove 301, a guide hole 602 is connected to the arc-shaped embedded groove 601, and a spring groove 603 is connected to the arc-shaped embedded groove 601 at the guide hole 602. A guide rod 604 is slidably connected in the guide hole 602, and one end of the guide rod 604 is connected to an arc-shaped pressure plate 605 matching the arc-shaped embedded groove 601 to ensure uniform distribution of pressure. The design of the guide rod 604 ensures the vertical movement of the arc-shaped pressure plate 605 to avoid tilting and jamming. The other end of the guide rod 604 is connected to a pressure rod 606 through a connecting rod. A first spring 607 is sleeved on the guide rod 604, and one end of the first spring 607 abuts against the lower surface of the arc-shaped pressure plate 605, and the other end of the first spring 607 abuts against the inner bottom of the spring groove 603; A fixing plate 608 is connected between the two rectangular steels 212. A positioning hole 609 matching the pressure rod 606 is provided 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 fault tolerance rate; When the tank body 400 is placed on the arc-shaped pressing plate 605, the arc-shaped pressing plate 605 is squeezed and moved downward, and the arc-shaped pressing plate 605 is embedded in 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, so as to realize the positioning and locking of the saddle 300; A clamping block 610 matching the clamping slot 302 is also fixedly connected to the channel steel 211 , so that after the saddle 300 is turned over, it abuts against the clamping block 610 , ensuring that the saddle 300 is vertically arranged at 90°.

[0045] In the initial state, when there is no load, the first spring 607 is in a natural state, the arc-shaped pressing plate 605 is located at the top of the arc-shaped embedding groove 601, and the pressing rod 606 is not inserted into the positioning hole 609; 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

[0046] In order to further improve the stability of the conveying device, the lifting mechanism 500 needs to be locked. Figure 9-12 , a locking assembly 700 for locking the lifting mechanism 500 is fixedly connected to the lower side of the fixing plate 608; 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.

[0047] 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 .

[0048] 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.

[0049] 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; 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.

[0050] 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.

[0051] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
