Description

Technical Field

[0001] This utility model relates to a multi-layer plate wrapping equipment used in the processing of multi-layer wrapped pressure vessels, and belongs to the technical field of auxiliary equipment for welding and clamping workpieces (B23K37 / 053). Background Technology

[0002] Multi-layer plate wrapping and tightening equipment in multi-layer wrapped pressure vessels typically consists of a gantry frame, hydraulic control motor, control valves, high-pressure pipelines, and hydraulic clamping devices. The mechanical frame serves as the tooling skeleton, while the hydraulic mechanism acts as the control and execution mechanism; both the mechanical frame and the hydraulic mechanism are integrated into a single unit. Existing multi-layer wrapping and tightening equipment is mainly attached to a welding operation platform or uses a separately fabricated gantry frame with the hydraulic control components assembled on top. The hydraulic clamping device usually consists of several hydraulic clamps working in conjunction with pipelines and valves, occupying a large area, being inconvenient to move, and having its applicable diameter range limited by the size of the frame structure. Summary of the Invention

[0003] The technical problem solved by this utility model is how to make the multilayer board wrapping and tightening equipment easy to move and quick to assemble.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a multi-layer board wrapping and tightening system with separate movement, which consists of two relatively independent hydraulic station control subsystems and wrapping and tightening subsystems.

[0005] The wrapping and tensioning subsystem includes a supporting moving trolley and a tensioning frame mechanism. The tensioning frame mechanism includes a hydraulic clamp, a hydraulic cylinder, a shackle, a hanging plate, a sleeve, a lifting lug, a crossbeam, and a wire rope. The hydraulic cylinder is fixedly connected to the hydraulic clamp and has an oil pipe inlet / outlet interface that connects to the hydraulic station control subsystem via a high-pressure oil outlet hose and a high-pressure oil return hose. The hanging plate, sleeve, and lifting lug are fixedly connected to the crossbeam, and the shackle is fixed to the hydraulic cylinder. One end of the wire rope is threaded and fixed to the shackle, and the other end is fixed to the hanging plate.

[0006] The supporting mobile trolley includes a first trolley frame and a support frame. The first trolley frame has a first caster under its base plate, and the support frame is fixed on the first trolley frame. The hydraulic station subsystem includes a second trolley frame, and the second trolley frame has a second caster under its base plate.

[0007] In use, the tensioning frame mechanism is lifted by a crane and suspended above the cylinder to be wrapped for multi-layer board wrapping, or placed on the supporting mobile trolley for storage.

[0008] Furthermore, a platform is formed on the upper part of the second trolley frame. An electric motor, a gear pump, a three-way relief valve, a rigid oil pipe, a manual directional valve, a high-pressure ball valve, a return oil pipe, and a high-pressure flexible oil pipe are arranged sequentially on the platform. An oil tank is located under the platform. The output end of the electric motor is connected to the input end of the gear pump. The output end of the gear pump is connected to the inlet of the three-way relief valve via the rigid oil pipe. One outlet of the three-way relief valve is connected to the inlet of the manual directional valve via the rigid oil pipe, and the other outlet of the three-way relief valve is connected to the return oil pipe. The outlet of the manual directional valve is connected to the inlet of the outlet high-pressure ball valve and the return high-pressure ball valve via outlet and return rigid pipes, respectively. The outlets of the outlet and return high-pressure ball valves are respectively connected to one end of the high-pressure outlet hose and the high-pressure return hose, respectively. The other ends of the high-pressure outlet hose and the high-pressure return hose are connected to the oil pipe inlet / outlet of the hydraulic cylinder.

[0009] The beneficial effects of this utility model are as follows: 1) Since the system of this utility model consists of two independent subsystems, a hydraulic station control subsystem and a wrapping and tensioning subsystem, and the two subsystems are connected to each other through detachable high-pressure soft oil pipes (including high-pressure oil outlet hoses and high-pressure oil return hoses), both subsystems can be easily moved; 2) Since the lifting and lowering of the tensioning frame mechanism is achieved by using a crane to hook the lifting lugs, the height of the tensioning frame mechanism can be adjusted according to the size of the shelving wrapping equipment, and it can be used to wrap the shelving of multi-layer wrapping containers with different inner diameters; 3) Since the tensioning frame mechanism is selectively lifted and suspended above the multi-layer shelving to be wrapped by a crane for shelving or placed on a support trolley for storage, the tensioning frame mechanism is not limited by the traditional gantry frame, and can be easily placed, used and disassembled; 4) Since the two subsystems are connected to each other through high-pressure soft oil pipes, the hydraulic station system can input oil pressure information, and thus transmit it to the hydraulic cylinder through the high-pressure soft oil pipes to control the hydraulic clamps; 5) Since the hydraulic clamps are fixed to the hanging plate by a shackle clamp, the hydraulic clamps can be easily disassembled and assembled. In summary, this utility model has a simple structure, is easy and quick to operate, is not limited by the diameter of the container, and is suitable for multi-layer wrapping containers of different sizes and structures. It is convenient to move or transport when performing multi-layer wrapping operations on-site.

[0010] Furthermore, the second trolley frame is equipped with a handle; and the oil outlet of the manual reversing valve is equipped with an oil pressure gauge. Attached Figure Description

[0019] To better describe the technical features and effects of this utility model, further explanation is provided below in conjunction with specific illustrations.

[0020] This utility model relates to a discretely movable multi-layer board wrapping and tightening system; see attached document. Figure 1 It consists of two relatively independent hydraulic station control subsystems and a wrapping and tensioning subsystem. For example... Figure 1 , Figure 2 and Figure 3 As shown, the bandaging tensioning subsystem includes a supporting moving trolley 100 and a tensioning frame mechanism 200. (As...) Figure 2 As shown, the supporting mobile trolley 100 includes a first trolley frame 11 and a support frame 10. First casters 12 are provided under the base plate of the first trolley frame 11, and the support frame 10 is fixed to the first trolley frame 11. Figure 3 As shown, the tensioning frame mechanism 200 includes a hydraulic clamp 1, a hydraulic cylinder 2, a shackle 3, a hanging plate 4, a sleeve 5, a lifting lug 6, a crossbeam 7, and a wire rope 8. The hydraulic cylinder 2 is fixedly connected to the hydraulic clamp 1 by a pin or bolt connection, facilitating regular maintenance and replacement. The hydraulic cylinder 2 is equipped with an oil pipe inlet / outlet interface that connects to the hydraulic station control subsystem via a high-pressure oil pipe. The hanging plate 4, sleeve 5, and lifting lug 6 are fixedly connected to the crossbeam 7. The shackle 3 is fixed to the hydraulic cylinder 2. One end of the wire rope 8 is threaded and fixed to the shackle 3, and the other end is fixed to the hanging plate 4. The supporting mobile trolley 100 and the tensioning frame mechanism 200 are two independent and separable structures. When the tensioning frame mechanism 200 needs to be moved, it can be placed on the supporting mobile trolley 100 for easy movement.

[0021] likeFigure 4 and Figure 5 As shown, the hydraulic station subsystem includes a second trolley frame 13. A second caster 25 is installed under the base plate of the second trolley frame 13, and a handle 28 is provided on the second trolley frame 13. A platform 9 is formed on the upper part of the second trolley frame 13. On the platform 9, a motor 23, a gear pump 21, a three-way relief valve 20, a rigid oil pipe, a manual directional valve 14, a high-pressure ball valve 16, a return oil pipe, and a high-pressure flexible oil pipe 17 are arranged sequentially. An oil tank 24 is located under the platform. The output end of the motor 23 is connected to the input end of the gear pump 21 via a coupling 22. The output end of the gear pump 21 is connected to the inlet of the three-way relief valve 20 via a rigid oil pipe. One outlet of the three-way relief valve 20 is connected to the handle 28 via a rigid oil pipe. The oil inlet of the manual directional valve 14 and the other outlet of the three-way relief valve 20 are connected to the return oil pipe. The oil outlet of the manual directional valve 14 is connected to the inlet of the high-pressure ball valve 16 and the high-pressure ball valve 26 via the oil outlet hard pipe 18 and the return hard pipe 19, respectively. The outlets of the high-pressure ball valve 16 and the high-pressure ball valve 26 are respectively connected to one end of the high-pressure oil outlet hose 17 and the high-pressure oil return hose 27. The other ends of the high-pressure oil outlet hose 17 and the high-pressure oil return hose 27 are respectively connected to the oil pipe inlet / outlet of the hydraulic cylinder 2. In this embodiment, there is a set of three high-pressure ball valves 16 and another set of three high-pressure ball valves 26. The oil outlet hard pipe 18 is divided into three branches and connected to the three high-pressure ball valves 16, and the return hard pipe 19 is divided into three branches and connected to the three high-pressure ball valves 26. Similarly, there are also three high-pressure oil outlet hoses 17 and three high-pressure oil return hoses 27, which are respectively connected to the three high-pressure ball valves 16 and the other set of three high-pressure ball valves 26. In this embodiment, an oil pressure gauge 15 is installed at the oil outlet of the manual reversing valve 14.

[0022] When using the discretely movable multi-layer board wrapping and tightening system of this utility model, such as... Figure 7 and Figure 8 As shown, the tensioning frame mechanism 200 utilizes the overhead crane's clamping lug 6 as a lifting platform during the wrapping operation. Its height can be adjusted according to the size of the multi-layer wrapping container, and the crane's rotation angle can rotate 360°, unrestricted by the gantry platform in traditional wrapping tensioning frames. The number of hydraulic clamps 1 and the dimensions of the tensioning frame mechanism 200 can be increased and changed according to the size of the wrapped layers. Before the multi-layer wrapping operation, two tooling plates 32 are welded to both sides of the layer approximately 150mm from the center of the longitudinal seam. This invention uses an overhead crane to lift the tensioning frame mechanism 200, adjusts its height according to the size of the multi-layer wrapping equipment, aligns the hydraulic clamps 1 with the center of the tooling plate 32, and adjusts the oil pressure according to the thickness of the wrapped layers. The layer wrapping device is controlled by the hydraulic clamps 1 according to the method described above.

[0023] The hydraulic station control subsystem starts working, providing power by starting the motor 23 to drive the coupling 22 and gear pump 21. First, the three high-pressure return ball valves 26 on the return oil hard pipe 19 are closed, and the three high-pressure outlet ball valves 16 on the outlet oil pipe 18 are opened. Oil is discharged from the oil tank 24 by manually operating the three-way relief valve 20, and the pressure value of the oil pressure gauge 15 is adjusted by manually controlling the three-way relief valve 20. When the oil pressure gauge 15 shows the required pressure value, the three high-pressure outlet ball valves 16 on the outlet oil hard pipe 18 are closed, and the hydraulic clamp 1 clamps the shelf plate by manually controlling the directional valve 14. When the clamping operation is completed, the hydraulic clamp 1 is released by controlling the manual directional valve 14, and the three high-pressure return ball valves 26 on the return oil hard pipe 19 are opened. The oil in the hydraulic cylinder 2 flows back to the oil tank 24 through the high-pressure outlet hose 27 and the return oil hard pipe 19, forming a cycle. The high-pressure outlet hose 17 delivers oil from the hydraulic station control subsystem to provide power for the hydraulic clamp 1 clamping.

[0024] Furthermore, the hydraulic station control subsystem can be upgraded to an intelligent device controlled by a PLC program file, transforming the original manual directional valve 14 into a touchscreen and button operation, forming an intelligent plywood wrapping system with adjustable pressure and speed, and automated and digitalized operation. Emergency stop buttons and electrical protection devices can also be added to the hydraulic station control subsystem to enhance system safety. Ultimately, this shortens the plywood wrapping time, significantly improves overall work efficiency and quality, and simplifies the operation process.

[0025] In addition to the above embodiments, the present invention may have other similar implementation methods, and technical solutions formed by equivalent transformations should all be covered by the protection scope claimed by the present invention.
