[0027] The following is combined with Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0028] Example 1

[0029] Reference Figure 1-3 A lifting device for a hull in a coating oven includes a lifting cylinder 1, a mechanical assembly, and a pneumatic assembly. The mechanical assembly includes an outer shell 2, which is a box-shaped structure without a bottom surface. The bottom edge of the outer shell 2 extends a certain area in all directions to increase the supporting force of the outer shell 2. The lifting cylinder 1 is vertically mounted on the upper surface of the outer shell 2, and the pneumatic assembly is horizontally mounted on the side of the outer shell 2. Specifically, the base of the lifting cylinder 1 is fixed to the upper surface of the outer shell 1 through four corner bolt holes and bolts.

[0030] The mechanical assembly also includes a connecting rod 3 and a C-shaped block 4; wherein, a through hole is opened on the upper surface of the outer shell 2, and one end of the connecting rod 3 is fixedly connected to the bottom surface of the lifting cylinder 1 through the through hole, and the surface of the other end of the connecting rod 3 is provided with a thread; at the same time, a nut 5 is provided on the bottom surface of the C-shaped block 4 on the side without an opening, and the nut 5 is fixedly connected to the thread on the connecting rod 3, thereby realizing a fixed connection between the connecting rod 3 and the C-shaped block 4, and the C-shaped block 4 is arranged in the outer shell 2 with the opening facing downward.

[0031] Specifically, the connecting rod 3 is vertically arranged in the outer shell 2; the top end of the connecting rod 3 is fixedly connected to the central connecting rod at the bottom of the lifting cylinder 1 by welding or bolts, and the bottom end of the connecting rod 3 is fixedly connected to the nut 5 set on the C-block 4.

[0032] During use, the lifting cylinder 1 switches between ascending, descending, and stationary states. Regardless of the state, the state of the lifting cylinder 1 and the connecting rod 3 remains consistent. During use, the lifting cylinder 1 can be connected to a corresponding gas delivery device to deliver or output gas to the lifting cylinder 1, ultimately achieving the desired operating state.

[0033] As for the gas delivery process, it can be controlled by a three-position five-way solenoid valve. Specifically, the three-position five-way solenoid valve has five channels, namely an air inlet, two exhaust ports, connector A and connector B. Connectors A and B are connected to the upper inlet and lower inlet of the lifting cylinder 1 respectively; when the upper inlet is fed with air, the operating structure in the lifting cylinder 1 moves downward, and when the lower inlet is fed with air, the operating structure in the cylinder 1 moves upward (the lifting cylinder 1 includes a base and an operating structure, and the position of the base remains unchanged during operation); the internal air inlet and return channels are changed according to the power supply of the solenoid valve A and B sides. When the A side is energized, the A connector is fed with air, and when the B side is energized, the B connector is fed with air, and both sides have their own exhaust ports; when not energized, the air inlet / exhaust are all closed to keep the pressure in the cavity from leaking out, thereby keeping the movement of the lifting cylinder 1 unchanged.

[0034] in accordance with Figure 1-3 The C-shaped block 4 comprises an unopened upper bottom surface, an open lower bottom surface, and two side surfaces. These four surfaces give the C-shaped block 4 a ring-shaped structure. In this embodiment, a nut 5 is welded to the unopened upper bottom surface of the C-shaped block 4, ensuring that the C-shaped block 4 is positioned within the outer shell 2 with its opening facing downward; this downward orientation refers to the direction of the open bottom surface of the outer shell 2. This arrangement facilitates the support and fixation of the support rod 7 and the transmission of force while securing the connecting rod 3. The nut 5 also facilitates the removal and installation of the C-shaped block 4.

[0035] The mechanical assembly also includes a milling block 6, a support rod 7, a stopper plate 8, and a base plate 9. The milling block 6 is mounted inside the C-shaped block 4, while the base plate 9 is fixedly connected to the bottom of the outer shell 2. The stopper plate 8 is located inside the outer shell 1 and abuts against the top surface of the base plate 9. Both the base plate 9 and the stopper plate 8 have holes of equal size at the same location. One end of the support rod 7 is fixedly connected to the milling block 6, while the other end extends through the holes in the base plate 8 and the stopper plate 8 to the exterior of the outer shell 2.

[0036] Specifically, milling block 6 is welded to the inner side of the unopened bottom surface of C-shaped block 4, wrapping around it. During use, milling block 6 locks support rod 7, providing both support and connection. Limit plate 8, positioned on support rod 7, is positioned precisely so that it rests on the upper surface of base plate 9, ensuring contact between them. At this point, lift cylinder 1 can be considered to be in the lowest position within its operating structure, allowing for adaptive adjustments based on specific circumstances.

[0037] The support rod 7 and the limiting plate 8 are fixed by welding, and the welding position can be the edge of the through hole on the limiting plate 8; the purpose is to enable the support rod 7 to drive the limiting plate 8 to move up and down.

[0038] At the same time, a double nut is provided at the connection between the support rod 7 and the upper surface of the limiting plate 8; wherein the double nut is two nuts 5 that fit together up and down, and the nut 5 located at the bottom of the double nut fits together with the limiting plate 8. Specifically, a thread is provided at the corresponding position on the support rod 7 to realize the connection between the double nut 5 and the support rod 7. The double nut structure in a fitted state and the nut 5 located at the bottom fits together with the limiting plate 8 can effectively make the position of the double nut and the limiting plate 8 on the support rod 7 more compact, so that the double nut is stably fixed on the support rod 7. The bottom plate 9 is also fixedly connected to the bottom edge of the outer shell 2 by welding or bolts. When the bottom plate connection is completed, the limiting plate 8 fits together with the bottom plate 9; thereby, the support rod 7 is limited by the double nut and the limiting plate 8, thereby avoiding the problem of the support rod 7 falling off.

[0039] As described above, during the use of the device, multiple lifting devices weld the bottom plate 9 to the upper surface of the outside of the oven, and correspond to the four corners of the upper hull inside the oven; and the support rod 7 in the device passes through the upper surface shell of the oven and is fixedly connected to the steel trough on the upper hull.

[0040] During operation, the lifting cylinder 1 is connected to the corresponding air supply device and the air supply is controlled by a three-position five-way solenoid valve, thereby realizing the rising / falling process of the lifting cylinder 1; and during operation, the lifting cylinder 1 drives the connecting rod 3, C-shaped block 4, milling block 6 and support rod 7 connected in sequence to operate, and realizes the rising / falling process of the upper hull in the oven through force conduction, thereby realizing the adjustment of the gap between the upper hull and the lower hull in the oven; at the same time, it can cooperate with the original lifting device in the oven to realize the adjustment of the gap between the upper hull and the lower hull, thereby providing double protection for the operation process and providing guarantee for the safety of the staff.

[0041] At the same time, in order to avoid malfunction of the lifting cylinder 1 after reaching the corresponding position, that is, the continuous movement of the lifting cylinder 1 due to damage to the solenoid valve, etc., it is necessary to limit the movement range of structures such as the connecting rod 3; therefore, a pneumatic component is set up in this application.

[0042] in accordance with Figure 1-3 The pneumatic assembly includes a pin cylinder 10, a housing 11, and a U-shaped pin piece 12. The pin cylinder 10 is arranged on the upper surface of the housing 11, and a through hole is opened on the upper surface of the housing 11. The bottom surface of the U-shaped pin piece 12 is fixedly connected to the pin cylinder 10 through the through hole.

[0043] Specifically, the structure of the housing 11 is similar to that of the outer housing 2, with the upper surface of the housing 11 being the upper bottom surface. The through-hole on the upper surface is the same size as the transverse area of ​​the pin cylinder 10, thereby enabling the pin cylinder 10 to be pushed into the interior of the housing 11. In this embodiment, the U-shaped pin piece 12 comprises a bottom edge and two side edges, which are connected to form a U-shaped structure. The bottom surface outside the bottom edge of the U-shaped pin piece 12 is fixedly connected to the pin cylinder 10 by welding, ultimately enabling the pin cylinder 10 to drive the U-shaped pin piece 12 to move and achieve the corresponding position limiting.

[0044] Reference Figure 1-3 The pneumatic component is laterally arranged at the upper position of the side of the outer shell 2, that is, the bottom edge of the shell 11 is fixed to the side of the outer shell 2 by welding or bolts; at the same time, a through hole is opened on the side of the outer shell 2 where the pneumatic component is provided, and at a position opposite to the bottom surface of the shell 11, which is used for the U-shaped pin piece 12 to extend into the interior of the outer shell 2.

[0045] At the same time, a through hole of the same size is opened at the same position on the side opposite to the side of the outer shell 2 where the pneumatic component is provided, for the U-shaped pin piece 12 to pass through the outer shell 2 and extend to the outside.

[0046] The lengths of the two sides of the U-shaped pin 12 are longer than the length of the housing 11 and the width of the outer housing 2. That is, part of the side of the U-shaped pin 12 extends into the interior of the outer housing 2 through the through hole, and the U-shaped pin 12 can penetrate the entire outer housing 2. Furthermore, the two sides of the U-shaped pin 12 are arranged horizontally within the housing 11; that is, the two sides of the U-shaped pin 12 are located on the same horizontal plane, which helps limit the range of motion of the support rod 7 and the connecting rod 3.

[0047] Reference Figure 1-3 The mechanical assembly also includes two pin track 13; wherein, the two pin track 13 are symmetrically arranged on two opposite sides of the outer shell 2; the two opposite sides here are the two sides adjacent to the side where the pneumatic assembly is arranged. The two pin track 13 are used to enable the U-shaped pin 12 to move laterally along the normal trajectory; this is because the U-shaped pin 12 may deviate from its route during operation, so that the two sides of the U-shaped pin 12 cannot reach the through hole on the other side, making it impossible for the U-shaped pin 12 to pass through the entire outer shell 2, and ultimately resulting in the inability to effectively limit the position; the pin track 13 can correct the travel route, so that the U-shaped pin 12 passes through the entire outer shell 2 along the normal trajectory. The position of the pin track 13 is adaptively set, and it is set at a position suitable for the movement of the U-shaped pin 12.

[0048] During use of the pneumatic assembly, the pin cylinder 10 pushes the U-shaped pin piece 12, causing the two sides of the U-shaped pin piece 12 to move laterally along the trajectory corrected by the pin piece track 13, so that the two sides of the U-shaped pin piece 12 pass through the entire outer shell 2 and ensure that part of the side of the U-shaped pin piece 12 is outside the outer shell 2. The gap between the two sides of the U-shaped pin piece 12 is smaller than the minimum spacing size of the C-shaped block 4, that is, the two sides of the U-shaped pin piece 12 are able to completely block the C-shaped block 4, thereby limiting the movement position of the C-shaped block 4 by the two sides of the U-shaped pin piece 12, and ultimately limiting the movement range of the connecting rod 3 and the support rod 7, thereby avoiding problems caused by malfunction of the lifting cylinder 1 after reaching the corresponding position.

[0049] At the same time, the control method of the pin cylinder 10 is the same as that of the lifting cylinder 1; and the material of the above-mentioned C-block, limit plate, U-shaped pin piece, support rod and connecting rod is alloy, the purpose is to ensure that the device has sufficient supporting force.

[0050] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
