Technical Field

[0001] This disclosure relates to the field of valve maintenance technology, and in particular to a valve maintenance platform. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the conveyed medium. They are widely used in various fields. For the disassembly and assembly of large and medium-sized valves, the traditional method is to set up triangular lifting frames on site or install lifting points on the roof, while using hand-operated hoists to lift the valves.

[0003] On the one hand, due to the limitations of on-site construction conditions, the installation of the triangular lifting frame and lifting points is quite difficult, resulting in low construction efficiency. On the other hand, the lifting method of the hand-operated hoist is prone to skewed lifting and tilting, which poses a greater risk of falling and collision, and thus a safety hazard.

[0028] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0029] like Figure 1 and Figure 2 As shown in the figure, this disclosure proposes a valve maintenance platform, including: a mobile trolley 1, a first platform 2, a first drive mechanism 3, a second platform 4, and a second drive mechanism 5. The first platform 2 is slidably disposed on the mobile trolley 1 along the vertical direction. The first drive mechanism 3 is disposed on the mobile trolley 1 and is used to drive the first platform 2 to move vertically along the mobile trolley 1. The second platform 4 is rotatably disposed on the first platform 2 along the circumferential direction of the mobile trolley 1 and is used to support the valve. The second drive mechanism 5 is disposed on the first platform 2 and is used to drive the second platform 4 to rotate circumferentially along the mobile trolley 1.

[0030] It is understandable that, since the first drive mechanism 3 drives the first platform 2 to move vertically along the moving trolley 1, and the second drive mechanism 5 drives the second platform 4 to rotate circumferentially along the moving trolley 1, the valve on the second platform 4 can be moved by the moving trolley 1, lifted and lowered by the first drive mechanism 3, and rotated by the second drive mechanism 5.

[0031] Therefore, through the cooperation of the mobile trolley 1, the first platform 2, the first drive mechanism 3, the second platform 4, and the second drive mechanism 5, the horizontal, height, and angle adjustments of the valve can be realized, thereby meeting the valve disassembly, assembly, and maintenance needs. At the same time, the overall structure of the maintenance platform is compact, occupies little space, and is not easily restricted by on-site construction conditions, thus ensuring high valve maintenance efficiency. Moreover, the operation of the maintenance platform is more stable, and there will be no problems with the skewed pulling and tilting of a hand-operated hoist. The risks of falling and collision are minimal, thus making the valve maintenance safer.

[0032] It should be noted that the mobile trolley 1 serves as the main support structure of the maintenance platform, supporting the first platform 2, the first drive mechanism 3, etc., and using its own movement function to adjust the horizontal position of the valve. The specific type of the mobile trolley 1 can be set according to actual needs, and there are no restrictions on it.

[0033] The first platform 2 is used to support the second platform 4, the second drive mechanism 5, etc., and to cooperate with the first drive mechanism 3 to realize the lifting function. The specific type of the first platform 2 can be set according to actual needs and there is no restriction. For example, the first platform 2 is a horizontally arranged plate structure.

[0034] The first drive mechanism 3 is used to drive the first platform 2 to rise and fall. The specific type of the first drive mechanism 3 can be set according to actual needs and there are no restrictions on it.

[0035] The second platform 4 is used to support the valve and to cooperate with the second drive mechanism 5 to realize the rotation function. The specific type of the second platform 4 can be set according to actual needs and there is no restriction. For example, the second platform 4 is a horizontally arranged plate structure and the second platform 4 is circular. The center of the second platform 4 is rotatably set on the first platform 2 by means of a bearing.

[0036] The second drive mechanism 5 is used to drive the second platform 4 to rotate. The specific type of the second drive mechanism 5 can be set according to actual needs and there are no restrictions on it.

[0037] like Figure 1 As shown, in some embodiments, the first drive mechanism 3 includes: a first drive arm 31, a second drive arm 32, and a hydraulic cylinder 33. One end of the first drive arm 31 is rotatably connected to the moving trolley 1, and the end of the first drive arm 31 away from the moving trolley 1 is slidably connected to the first platform 2. One end of the second drive arm 32 is rotatably connected to the first platform 2, and the end of the second drive arm 32 away from the first platform 2 is slidably connected to the moving trolley 1. The middle part of the second drive arm 32 is rotatably connected to the middle part of the second drive arm 32. The piston rod end of the hydraulic cylinder 33 is rotatably connected to the moving trolley 1, and the cylinder end of the hydraulic cylinder 33 is rotatably connected to the second drive arm 32.

[0038] Understandably, since one end of the first drive arm 31 is rotatably connected to the moving trolley 1, and the end of the first drive arm 31 away from the moving trolley 1 is slidably connected to the first platform 2, the first drive arm 31 can drive the first platform 2 by rotation. Simultaneously, since one end of the second drive arm 32 is rotatably connected to the first platform 2, and the end of the second drive arm 32 away from the first platform 2 is slidably connected to the moving trolley 1, the second drive arm 32 can drive the first platform 2 by rotation. Therefore, by utilizing the cooperation between the first drive arm 31 and the second drive arm 32, the first platform 2 can be slidably arranged vertically. At the same time, by coordinating the hydraulic cylinder 33's drive between the moving trolley 1 and the second drive arm 32, the first platform 2 can be raised and lowered, thereby meeting the valve disassembly, assembly, and maintenance needs at different heights on the second platform 4.

[0039] It should be noted that the first drive arm 31 and the second drive arm 32 are used to form a scissor boom structure, which can not only realize the vertical sliding arrangement of the first platform 2, but also realize the lifting control of the first platform 2 under the drive of the hydraulic cylinder 33. The specific types of the first drive arm 31 and the second drive arm 32 can be set according to actual needs and there is no restriction. For example, the first drive arm 31 and the second drive arm 32 can both be H-shaped boom structures. The rotation center axis of the first drive arm 31, the rotation center axis of the second drive arm 32, and the rotation center axis between the first drive arm 31 and the second drive arm 32 are parallel to each other. The end of the first drive arm 31 away from the moving trolley 1 and the end of the second drive arm 32 away from the first platform 2 can both be arranged horizontally by using rollers.

[0040] The hydraulic cylinder 33 is used to drive the first drive arm 31 and the second drive arm 32 by extending and retracting the piston rod end, thereby realizing the lifting and lowering of the first platform 2. The specific type of the hydraulic cylinder 33 can be set according to actual needs and is not limited thereto. For example, the hydraulic cylinder 33 can be a jack structure, which uses the hydraulic control end to control the extension and retraction of the piston rod.

[0041] like Figure 1 As shown, in some embodiments, the first drive mechanism 3 further includes an operating handle 34, which is connected to the hydraulic control end of the hydraulic cylinder 33, and the operating handle 34 is used to drive the hydraulic cylinder 33 to extend or retract.

[0042] Understandably, because the operating handle 34 and the hydraulic cylinder 33 are connected by a hydraulic control drive, maintenance personnel can use the operating handle 34 to control the extension and retraction of the hydraulic cylinder 33, thereby achieving the lifting and lowering control of the valves on the second platform 4. The design of the operating handle 34 makes the operation of the maintenance platform simpler and more convenient.

[0043] It should be noted that the operating handle 34 is used to control the oil at the hydraulic control end of the hydraulic cylinder 33, so as to realize the extension and retraction control of the hydraulic cylinder 33 by using the propulsion or release of the oil. The specific type of the operating handle 34 can be set according to actual needs, and there is no restriction on it.

[0044] like Figure 1 and Figure 2 As shown, in some embodiments, the second drive mechanism 5 includes: a first gear 51, a second gear 52, and a first drive handwheel 53. The first gear 51 is sleeved on the second platform 4, the second gear 52 is rotatably mounted on the first platform 2, and the second gear 52 meshes with the first gear 51. The first drive handwheel 53 is rotatably mounted on the first platform 2, and the first drive handwheel 53 and the second gear 52 are connected in a transmission manner. The first drive handwheel 53 is used to drive the second gear 52 to rotate.

[0045] It is understandable that, since the first drive handwheel 53 is rotatably mounted on the first platform 2 and the first drive handwheel 53 is connected to the second gear 52, the first drive handwheel 53 can drive the second gear 52 to rotate. Furthermore, since the first gear 51 is mounted on the second platform 4 and the second gear 52 is rotatably mounted on the first platform 2, and the second gear 52 and the first gear 51 mesh, the rotation of the second gear 52 can drive the rotation of the first gear 51, thereby realizing the angle adjustment of the second platform 4 and thus meeting the disassembly, assembly, and maintenance needs of the valves on the second platform 4 at different angles.

[0046] It should be noted that the first gear 51 and the second gear 52 are used for transmission between the first drive handwheel 53 and the first platform 2. The specific types of the first gear 51 and the second gear 52 can be set according to actual needs and there is no limitation. For example, the central axis of the first gear 51 coincides with the central axis of the first platform 2, and the central axis of the second gear 52 is parallel to the central axis of the first gear 51. The diameter of the second gear 52 is smaller than the diameter of the first gear 51.

[0047] The first drive handwheel 53 is used to drive the second gear 52 to rotate. The specific type of the first drive handwheel 53 can be set according to actual needs and is not limited thereto. For example, the first drive handwheel 53 is a ring-shaped handwheel structure.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the second drive mechanism 5 further includes a gearbox 54 and a drive shaft 55. The gearbox 54 is disposed on the first platform 2, and the second gear 52 is disposed on the power output end of the gearbox 54. The drive shaft 55 is disposed on the power input end of the gearbox 54, and the first drive handwheel 53 is sleeved on one end of the drive shaft 55.

[0049] Understandably, since the second gear 52 is located at the power output end of the gearbox 54 and the drive shaft 55 is located at the power input end of the gearbox 54, and the first drive handwheel 53 is sleeved on one end of the drive shaft 55, the rotation of the first drive handwheel 53 can drive the drive shaft 55 to rotate synchronously, and the rotation of the drive shaft 55 can drive the second gear 52 to rotate by the power conversion of the gearbox 54, thereby realizing the drive of the first gear 51 by the first drive handwheel 53, and thus realizing the angle adjustment of the second platform 4.

[0050] It should be noted that the gearbox 54 is used for power conversion between the drive shaft 55 and the second gear 52. The specific type of gearbox 54 can be set according to actual needs and there is no limitation. For example, the gearbox 54 can be a transmission structure with two bevel gears meshing. The power output end of the gearbox 54 is located in the vertical direction and the power input end is located in the horizontal direction. That is to say, the central axis of the second gear 52 is located in the vertical direction and the central axis of the drive shaft 55 is located in the horizontal direction.

[0051] The drive shaft 55 is used for transmission between the first drive handwheel 53 and the power input end of the gearbox 54. The specific type of drive shaft 55 can be set according to actual needs and is not limited thereto.

[0052] like Figure 2 As shown, in some embodiments, the second drive mechanism 5 further includes a second drive handwheel 56, which is sleeved on the end of the drive shaft 55 away from the first drive handwheel 53.

[0053] Understandably, since the second drive handwheel 56 is mounted on the end of the drive shaft 55 away from the first drive handwheel 53, the rotation of the second drive handwheel 56 can drive the drive shaft 55 to rotate synchronously, thereby also enabling the angle adjustment of the second platform 4. Thus, through the cooperation of the first drive handwheel 53 and the second drive handwheel 56, the operation of the maintenance platform becomes more flexible and convenient.

[0054] It should be noted that the second drive handwheel 56 is used to drive the second gear 52 to rotate, so as to cooperate with the first drive handwheel 53 to achieve a redundant design. The specific type of the second drive handwheel 56 can be set according to actual needs and there is no restriction. For example, the second drive handwheel 56 is a ring-shaped handwheel structure.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the maintenance platform further includes: a plurality of sliders 6, which are disposed on the first platform 2 and slidably connected to the second platform 4, and the plurality of sliders 6 are distributed at intervals along the circumference of the second platform 4.

[0056] It is understandable that since the slider 6 is set on the first platform 2 and the second platform 4 is slidably connected to the slider 6, the multiple sliders 6 are distributed at intervals along the circumference of the second platform 4, so that the first platform 2 can use the multiple sliders 6 to achieve stable support for the second platform 4, without affecting the angle adjustment of the second platform 4.

[0057] It should be noted that the slider 6 is used to support the second platform 4 and enable the second platform 4 to rotate around the central axis. The specific type of the slider 6 can be set according to actual needs and there is no restriction on it. For example, the slider 6 can be a block structure.

[0058] In some embodiments, the slider 6 is made of polytetrafluoroethylene.

[0059] Understandably, since the slider 6 is made of polytetrafluoroethylene (PTFE), the slider 6 can utilize the self-lubricating properties of PTFE to reduce its own friction, thereby reducing the obstruction to the second platform 4 and ensuring the stable rotation of the second platform 4.

[0060] It should be noted that polytetrafluoroethylene, also known as Teflon, is a high molecular polymer obtained by polymerizing tetrafluoroethylene as a monomer.

[0061] like Figure 1 As shown, in some embodiments, the mobile trolley 1 includes: a base 11 and a plurality of wheels 12, a first platform 2 is slidably disposed on the base 11 along the vertical direction of the base 11, and a first drive mechanism 3 is disposed on the base 11, the wheels 12 are disposed at the bottom of the base 11, and the plurality of wheels 12 are distributed at intervals along the circumference of the base 11.

[0062] It is understandable that, since the traveling wheels 12 are located at the bottom of the base 11 and multiple traveling wheels 12 are distributed at intervals along the circumference of the base 11, the base 11 can move using multiple traveling wheels 12, thereby realizing the horizontal movement of components such as the first platform 2 and the second platform 4 on the base 11, and thus meeting the disassembly, assembly and maintenance needs of valves on the second platform 4 at different horizontal positions.

[0063] It should be noted that the base 11 is used to support components such as the first platform 2 and the first drive mechanism 3. The specific type of the base 11 can be set according to actual needs and there is no limitation thereto. For example, the base 11 can be a seat structure.

[0064] The traveling wheel 12 is used for the movement of the base 11. The specific type of the traveling wheel 12 can be set according to actual needs and is not limited thereto. For example, the traveling wheel 12 can be a universal wheel with locking function.

[0065] like Figure 1 As shown, in some embodiments, the mobile trolley 1 includes a push-pull armrest 13, which is disposed at one end of the base 11.

[0066] Understandably, since the push-pull handle 13 is located at one end of the base 11, the operator can use the push-pull handle 13 to move the base 11. Thus, the push-pull handle 13 facilitates the adjustment of the valve position on the second platform 4 in the horizontal direction, making it more convenient to use.

[0067] It should be noted that the push-pull armrest 13 is used for the push-pull movement of the base 11. The specific type of push-pull armrest 13 can be set according to actual needs, and there are no restrictions on it.

Furthermore, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.
