Description

Technical Field

[0001] The utility model belongs to the technical field of production line maintenance, and in particular relates to a ash discharge valve disassembly and assembly lifting device. Background Art

[0002] Ash discharge valves are bound to fail during production and operation. During disassembly and maintenance, due to location restrictions and the bulkiness of the ash discharge valve, the disassembly and assembly of the ash discharge valve usually requires the use of lifting equipment or manual handling. The operation process is cumbersome and there are safety risks. This is not only labor-intensive and inefficient, but also poses safety hazards. Existing lifting devices cannot be used directly for ash discharge valves. Unlike general valves, ash discharge valves usually have structures such as flanges for installing electric motors, which often cause the center of gravity of the ash discharge valve to shift, and there is a risk of overturning if placed directly on a plane. In addition, existing lifting devices are often complex in structure and are not suitable for industrial environments with small spaces.

[0003] For example, Chinese patent CN202011569478.8 discloses a lifting gas valve disassembly and assembly device, which uses a support column to fix the gas valve and a hydraulic lifting device to drive the gas valve to rise and fall. Its lifting structure is complex and the lifting stroke is short. The support shaft and clamping mechanism for fixing the gas valve cannot be used for disassembly and assembly of the ash unloading valve.

[0004] Therefore, providing a lifting device with a simple structure and suitable for disassembly and assembly of an ash discharge valve is a technical problem to be solved urgently in the art. Utility Model Content

[0005] In view of the existing phenomenon, the technical problem to be solved by the utility model is to provide a ash discharge valve disassembly and assembly lifting device to at least solve one of the above technical problems.

[0006] The technical solution provided in the present application is a ash unloading valve disassembly and assembly lifting device, including a liftable platform and a driving part for driving the platform to lift and lower, and the platform is provided with a fixing part for fixing the ash unloading valve and a supporting part for supporting the ash unloading valve.

[0007] Furthermore, the fixing portion includes a through hole corresponding to the position of the mounting screw hole of the ash discharge valve.

[0008] Furthermore, a plurality of through holes are symmetrically arranged.

[0009] Furthermore, the through hole is in a strip shape suitable for ash discharge valves of various specifications.

[0010] Furthermore, the height of the support portion is adjustable.

[0011] Further, the supporting part includes a bolt and a nut threadedly connected to the bolt and capable of adjusting the height of the bolt.

[0012] Furthermore, the support portion also includes a support member connected to the bolt, and the support member is in surface contact with the ash discharge valve.

[0013] Furthermore, the driving part is a scissor-type lifting structure.

[0014] Furthermore, the driving part includes a scissor arm connected to the platform, and also includes a screw rod and a threaded slider threadedly connected to the screw rod. The threaded slider is transmission-connected to the scissor arm and can drive the ends of the scissor arm to move toward or away from each other.

[0015] Furthermore, an operating member for facilitating manual rotation of the screw rod is provided at one end of the screw rod away from the frame.

[0016] The beneficial effects of this application are:

[0017] 1. The present application provides a lifting device for disassembling and assembling an ash unloading valve, which has a liftable platform and a driving part for driving the platform to lift and lower. The platform is provided with a fixing part for fixing the ash unloading valve and a supporting part for supporting the ash unloading valve. In some relatively simple and lightweight lifting devices, even if a fixed structure is provided to fix the ash unloading valve to a plane, the fixing structure may become unstable, or even cause the lifting device to overturn. In order to enable the ash unloading valve to be more firmly fixed to the lifting device, the platform of the present application is provided with a supporting part for supporting the ash unloading valve, especially for supporting a structure that causes the ash unloading valve to overturn easily. When the ash unloading valve needs to be disassembled and assembled, the operator can first drive the platform to the bottom of the ash unloading valve through the driving part, fix the ash unloading valve to the platform using the fixing part, and make the supporting part support the ash unloading valve, and then lower or raise the ash unloading valve through the driving part.

[0018] 2. The present application also provides a preferred solution for the ash discharge valve disassembly and assembly lifting device, including: providing a through hole as a fixing part; providing a bolt as a supporting part; using a scissor-type lifting mechanism as a driving part, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Please refer to Figure 1 Some embodiments of the present application provide an ash unloading valve disassembly and assembly lifting device, including a liftable platform 1 and a driving part for driving the platform 1 to lift and lower. The platform 1 is provided with a fixing part 11 for fixing the ash unloading valve and a supporting part for supporting the ash unloading valve.

[0025] Unlike general valves, ash discharge valves usually have structures such as flanges for mounting electric motors, which causes the center of gravity of the ash discharge valve to shift, and there is a risk of overturning when placed directly on a plane. In some relatively simple and lightweight lifting devices, even if a fixed structure is set to fix the ash discharge valve on a plane, it may cause the fixed structure to be unstable and even cause the lifting device to overturn. In order to enable the ash discharge valve to be more firmly fixed to the lifting device, the platform 1 of the present application has a support portion for supporting the ash discharge valve, especially supporting the structure that causes the ash discharge valve to overturn easily.

[0026] When the ash unloading valve needs to be disassembled and assembled, the operator can first drive the platform 1 to the bottom of the ash unloading valve through the driving part, fix the ash unloading valve to the platform 1 using the fixing part 11, and make the supporting part support the ash unloading valve, and then lower or raise the ash unloading valve through the driving part.

[0027] In some embodiments, the fixing portion 11 includes a through hole corresponding to the position of the mounting screw hole of the ash discharge valve. The ash discharge valve is usually installed vertically and has a vertical mounting screw hole. The through hole is provided on the platform 1 so that the mounting screw hole of the ash discharge valve can be used for fixing. Preferably, a plurality of through holes are symmetrically provided. Providing more through holes can provide a better fixing effect.

[0028] In some embodiments, the through hole is in a strip shape suitable for ash discharge valves of various specifications. Considering that ash discharge valves of various specifications have different diameters, setting the through hole in a strip shape can make the ash discharge valve disassembly and assembly lifting device suitable for ash discharge valves of various specifications.

[0029] In some embodiments, the height of the support portion is adjustable. Considering that ash discharge valves of different specifications have different structural dimensions that cause overturning, setting the height of the support portion to be adjustable allows it to support different ash discharge valves.

[0030] As a specific implementation of a support portion, the support portion includes a support bolt 12 and a nut threadedly connected to the support bolt 12 and capable of adjusting the height of the support bolt 12 . The height of the bolt can be adjusted by rotating the nut.

[0031] To make the supporting effect more stable and effective, in some embodiments, the supporting part further includes a supporting member 13 connected with the bolts, and the supporting member 13 is in surface contact with the ash discharge valve. For example, for an ash discharge valve that uses a flange to connect the motor to cause the center of gravity to shift, the part to be supported is a cylinder, and the supporting member 13 can be set as an arc-shaped sheet with an opening facing upward.

[0032] In some embodiments, the driving part is a scissor-type lifting structure. The scissor-type structure has the advantages of simple structure, easy installation, large travel, stable lifting, etc., and is suitable for the use scenario of this application.

[0033] Specifically, in some embodiments, the driving unit includes a scissor arm 21 connected to the platform 1, a screw rod 22, and a threaded slider 23 threadedly connected to the screw rod 22. The threaded slider 23 is connected to the scissor arm 21 and can drive the ends of the scissor arm 21 to move toward or away from each other. When in use, the screw rod 22 can be rotated to drive the threaded slider 23 to move, and the platform 1 can be raised and lowered through the scissor arm 21. Preferably, the end of the screw rod 22 also includes an operating member 24, which is convenient for the operator to rotate the screw rod 22.

[0034] In some embodiments, a brakeable roller 31 is further included to facilitate the movement and fixation of the ash discharge valve disassembly and assembly lifting device.

[0035] Combine the following Figure 1 A specific implementation of the present application is listed, namely, a ash discharge valve disassembly and assembly lifting device.

[0036] The ash discharge valve disassembly and assembly lifting device comprises a platform 1, a driving part, and a frame 3.

[0037] The platform 1 is provided with a fixing portion 11 for fixing the ash discharge valve and a supporting portion for supporting the ash discharge valve. The fixing portion 11 is composed of eight strip-shaped through holes arranged in a ring. The supporting portion includes a supporting bolt 12 that passes through the platform 1, and an adjusting nut arranged below the platform 1 and capable of adjusting the height of the supporting bolt 12. A supporting member 13 is fixedly connected to the supporting bolt 12, and the supporting member 13 is specifically a circular arc sheet.

[0038] The driving part includes scissor arms 21 spaced apart along the first horizontal direction, including two first scissor arms 211 and two second scissor arms 212. A plurality of connecting shafts 213 are provided between the two first scissor arms 211, and a plurality of connecting shafts 213 are provided between the two second scissor arms 212. One end of the first scissor arm 211 is hinged to the platform 1, and the other end is movably connected to the frame 3 and can move along the second horizontal direction. The second horizontal direction is perpendicular to the first horizontal direction. One end of the second scissor arm 212 is hinged to the frame 3, and the other end is movably connected to the platform 1 and can move along the second horizontal direction. Both the frame 3 and the platform 1 are provided with a slide groove opened along the second horizontal direction, and a slider is provided in the slide groove, and one end of the scissor arm 21 that can move along the second horizontal direction is hinged to the slider.

[0039] The driving part also includes a screw rod 22, which is arranged on the frame 3. A threaded slider 23 is threadedly connected to the screw rod 22. The threaded slider 23 is connected to the connecting shaft at the lower end of the first scissor arm 211, and can drive the lower end of the first scissor arm 211 to move. An operating member 24 is provided at one end of the screw rod 22 away from the frame 3 to facilitate manual rotation of the screw rod.

[0040] The frame 3 includes brakeable rollers 31 .

[0041] When using the device to dismantle a suspended ash unloading valve, first move the device to a suitable position below the ash unloading valve via a brakeable roller and lock it with a foot brake. Then, rotate the screw rod 22 as needed to adjust the height of the platform 1 to achieve lifting and lowering movement. Place the ash unloading valve to be disassembled on the platform 1 and fix it to the fixing part 11. Then adjust the height of the supporting part to prevent the ash unloading valve from overturning. Subsequently, rotate the screw rod 22 to drive the platform 1 to descend, and then move it to a safe and large space to repair the ash unloading valve.

[0042] When using the device to install the ash discharge valve, the above-mentioned fixing and supporting operations are performed first, and then the ash discharge valve is moved to the installation position through the lifting device, and then the screw rod 22 is rotated as needed to adjust the height of the scissor arm 21 and the platform 1 to achieve lifting movement to raise the ash discharge valve to be installed to a suitable position for manual installation. The ash discharge valve disassembly and assembly lifting device has a simple structure, convenient operation, and flexible movement, which greatly improves the efficiency and safety of the ash discharge valve disassembly and assembly.
