Description

Technical Field

[0001] This utility model relates to the structure of components of a tire vulcanizing machine, specifically a quick-release structure for a hot plate steam chamber top-mounted booster cylinder. Background Technology

[0002] Currently, the booster cylinder in the hot plate steam chamber of a conventional hydraulic vulcanizing machine is usually installed at the bottom. This bottom-mounted installation method of booster cylinder has the problem of inconvenient maintenance. When the booster cylinder is repaired or replaced in the tire factory, because the booster cylinder is suspended at the top of the base or pit, and there are many pipes in the base or pit, the operating space is narrow, and it can only be operated manually. In addition, the booster cylinder itself is heavy, making it very difficult to disassemble and move it out of the base or pit by hand. Moreover, there are certain safety hazards for people working at the bottom of the vulcanizing machine.

[0003] For safe maintenance, disassembly, and easy removal, the booster cylinder has been further designed with an upper mounting, placed on the lower seat plate inside the upper steam chamber. However, this upper-mounted booster cylinder has a lower support plate, heat insulation plate, and lower heating plate spanning across it. A central mechanism is also installed above and at the center holes of the lower support plate, heat insulation plate, and lower heating plate. When the upper-mounted booster cylinder needs maintenance or replacement, the internal pressure steam connection pipe of the central mechanism must be disassembled first, the upper and lower ring cylinders must be disconnected, the central mechanism must be lifted away, and then the assembly of the lower support plate, heat insulation plate, and lower heating plate must be lifted away before the upper-mounted booster cylinder can be disassembled and removed for maintenance or replacement. This disassembly and assembly process is very cumbersome and greatly increases the maintenance workload. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a quick-disassembly structure for an upper-mounted booster cylinder in a hot plate steam chamber. After simply lifting the assembly of the lower support plate, heat insulation plate, and lower hot plate in one step, the upper-mounted booster cylinder can be immediately disassembled and lifted out for maintenance and replacement.

[0005] A quick-release structure for a hot plate steam chamber with an upper-mounted booster cylinder, capable of solving existing technical problems, includes an upper steam chamber mounted on a lower base plate. Within the lower part of the upper steam chamber, a lower hot plate, a heat insulation plate, and a lower support plate are assembled in upper, middle, and lower positions. A central mechanism is provided that penetrates the lower hot plate, heat insulation plate, lower support plate, and lower base plate. Booster cylinders are evenly distributed around the circumference of the lower base plate, with the cylinder rods of each booster cylinder supporting and connecting upwards to the bottom of the lower support plate. The key difference is:

[0006] 1. The lower support plate, heat insulation plate and lower heating plate have a central hole I with the same diameter. The central hole I is a through hole of the central mechanism and the diameter of the central hole I is larger than the outer diameter of the ring seat of the central mechanism.

[0007] 2. A lifting guide mechanism I is provided between the lower support plate and the lower seat plate. The lifting guide mechanism I includes guide rod and guide sleeve pairs I evenly distributed around the circumference. Each guide rod and guide sleeve pair I includes a guide rod I and a guide sleeve I that are slidably engaged. The guide rod I is installed at the bottom of the lower support plate, and the guide sleeve I is installed inside the lower seat plate.

[0008] 3. A lifting guide mechanism II is provided between the central mechanism and the lower seat plate. The lifting guide mechanism II includes a central mechanism cylinder and a positioning sleeve II that are slidably fitted. The positioning sleeve II is installed in the central hole II of the lower seat plate.

[0009] 4. A lifting guide mechanism III is also provided between the central mechanism and the lower seat plate. The lifting guide mechanism III includes a slidingly fitted central mechanism internal pressure inlet / outlet pipe and a positioning sleeve III, which is located inside the lower seat plate.

[0010] Furthermore, one structure of the positioning sleeve II includes an upper positioning sleeve II and a lower positioning sleeve II, with the upper and lower positioning sleeve II extending beyond the top and bottom of the lower base plate, respectively.

[0011] Furthermore, one structure of the positioning sleeve III includes a through hole penetrating the lower base plate, and positioning rings III are provided at the upper and lower openings of the through hole.

[0012] Furthermore, the cylinder body of each booster cylinder is located in the corresponding cylinder hole on the lower seat plate and is fastened to the top of the lower seat plate. Each booster cylinder has a screw rod, which passes through the lower heating plate, the heat insulation plate and the lower support plate before connecting to the piston.

[0013] The beneficial effects of this utility model are:

[0014] The quick-release structure of the hot plate steam chamber top-mounted booster cylinder of this utility model eliminates the need to disassemble the internal pressure steam connection pipes of the central mechanism, disconnect the upper and lower ring cylinders, or lift the central mechanism during maintenance and replacement of the top-mounted booster cylinder. Instead, the damaged booster cylinder can be disassembled and removed for maintenance and replacement by directly lifting the assembly of the lower support plate, heat insulation plate, and lower hot plate with the help of an on-site crane. This is safe, convenient, and quick, simplifying the disassembly process and saving a lot of maintenance costs and downtime. Attached Figure Description

[0019] This utility model relates to a quick-release structure for a hot plate steam chamber top-mounted booster cylinder, comprising an upper steam chamber 2 mounted on a lower base plate 1. Within the lower part of the upper steam chamber 2, a lower hot plate 4, a heat insulation plate 13, and a lower support plate 3 are coaxially assembled in upper, middle, and lower positions. The lower support plate 3, heat insulation plate 13, and lower hot plate 4 all have a central hole I of the same diameter. A central mechanism is coaxially provided through the central hole I of all three and the central hole II of the lower base plate 1. The diameter of the central hole I is slightly larger than the ring seat 5 of the central mechanism (component I of the central mechanism). The outer diameter; The lower seat plate 1 is circumferentially distributed with force-applying cylinders 14, the cylinder body of each force-applying cylinder 14 is located in a corresponding cylinder hole on the lower seat plate 1, and the end of each cylinder body is fastened to the top of the lower seat plate 1 with screws 18. A screw 15 is provided for each plunger 14-1 (extending upwards from the cylinder body) corresponding to each force-applying cylinder 14. Each screw 15 passes through the lower heating plate 4, the heat insulation plate 13, and the lower support plate 3 from top to bottom, and is bolted to the plunger 14-1, thus fastening each plunger 14-1 to the bottom of the lower support plate 3. Figure 1 , Figure 2 As shown.

[0020] A lifting guide mechanism I (located inside the force cylinder 14) is provided between the lower support plate 3 and the lower seat plate 1 to guide the upper and lower lifting and adjusting movement of the lower support plate 3. A lifting guide mechanism II and a lifting guide mechanism III are provided between the central mechanism and the lower seat plate 1.

[0021] The lifting guide mechanism I includes three circumferentially distributed guide rod and guide sleeve pairs I. Each guide rod and guide sleeve pair I includes a slidingly fitted guide rod I6 and a guide sleeve I7. The guide rod I6 is installed inside the bottom of the lower support plate 3, and the guide sleeve I7 is installed in a corresponding sleeve hole in the lower base plate 1. Figure 1 , Figure 2 As shown.

[0022] The lifting guide mechanism II includes a slidingly fitted central mechanism cylinder 8 (component II of the central mechanism) and a positioning sleeve II (an extended positioning sleeve II, used to ensure that the central mechanism remains vertical during the lifting and lowering process). The positioning sleeve II is installed in the central hole II of the lower seat plate 1 and includes an upper positioning sleeve II 9 and a lower positioning sleeve II 10, with the upper and lower positioning sleeves II 9 and 10 extending beyond the top and bottom of the lower seat plate 1, respectively. The lifting guide mechanism III includes a slidingly fitted central mechanism internal pressure inlet / outlet pipe 11 (component III of the central mechanism) and a positioning sleeve III. The positioning sleeve III includes a through hole penetrating the lower seat plate 1, with positioning rings III 12 at both the upper and lower ends of the through hole. Figure 1 , Figure 2 As shown.

[0023] Two support rods 16 are symmetrically arranged below the lower support plate 3 (misaligned with the internal pressure inlet / outlet pipe 11 of the central mechanism). Each support rod 16 passes through the lower base plate 1, with its upper end connected to the bottom of the lower support plate 3, and its lower end threadedly connected to the lower ring cylinder rod 17. Figure 2 As shown.

[0024] The operation mode of this utility model is as follows:

[0025] When the booster cylinder 14 needs to be repaired or replaced, first disconnect the steam inlet and outlet pipes of the lower heating plate 4, then remove the screws 15 connecting the lower support plate 3 and the plunger 14-1, and then disconnect the connection between the branch rod 16 and the cylinder rod 17 of the lower ring cylinder. The assembly of the lower support plate 3, the lower heating plate 4, and the heat insulation plate 13 can then be lifted out of the central mechanism. Then, remove the screws 18 that fix the booster cylinder 14, and the booster cylinder 14 can be lifted out of the vulcanizing machine for repair or replacement. This simplifies the traditional and cumbersome disassembly steps, greatly reduces maintenance workload and downtime, saves a lot of maintenance costs, and the operation is safe, convenient, and quick.
