Description

Technical Field

[0001] This utility model relates to the field of lifting platforms, and in particular to a lifting platform device for boiler furnace maintenance. Background Technology

[0002] Boilers operate under high temperature and pressure for extended periods, requiring regular maintenance to ensure normal operation and prevent accidents. Due to their considerable height, personnel-carrying lifting platforms are typically used for convenient inspection and maintenance. These platforms are specially designed devices with stable structures and safe working platforms, allowing for vertical movement and elevation of personnel to higher positions. During boiler maintenance, workers can safely access the boiler's location to perform necessary maintenance and inspections.

[0003] Currently, Chinese Patent Publication No. CN221854168U discloses a boiler maintenance lifting platform, which includes an electric trolley. A lift is mounted on the top of the electric trolley, and a maintenance platform is fixedly mounted on the top of the lift. A U-shaped protective frame is fixedly mounted on the side of the top of the maintenance platform. This boiler maintenance lifting platform, through the coordinated use of the electric trolley, lift, maintenance platform, movable baffle, protective rod, slot, U-shaped protective frame, motor, door, extension plate, control switch, limit groove, threaded rod, transmission mechanism, and threaded groove, allows the extension plate to move outward a certain distance from the left side of the maintenance platform, effectively expanding the maintenance platform space. Maintenance personnel can then move to the top of the extension plate to reach the required maintenance position. The mobility of the extension plate significantly expands the maintenance platform space, greatly improving the flexibility of the device.

[0004] However, because the center of gravity of the boiler maintenance lifting platform is high when it is working, it is prone to tipping over if the ground is uneven. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model proposes a boiler furnace maintenance lifting platform device to solve the problem that the device in the prior art is prone to tipping over due to uneven ground.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A boiler furnace maintenance lifting platform device includes a base, a horizontal adjustment mechanism disposed on the top of the base, a lifting mechanism disposed on the top of the horizontal adjustment mechanism, and a working platform disposed on the top of the lifting mechanism.

[0008] The leveling mechanism includes a base plate, a rotating mechanism disposed at the bottom of the base plate, an angle adjusting mechanism disposed at the top of the base plate, and a top plate disposed at the top of the angle adjusting mechanism; the base plate is rotatably connected to the base via the rotating mechanism, a first level is disposed on the front side of the top plate, and a second level is disposed on the right side of the top plate.

[0009] The angle adjustment mechanism includes a support base and a hydraulic telescopic cylinder; the support base is fixedly installed on the top left side of the base plate, and the upper end of the support base is hinged to the top plate; the hydraulic telescopic cylinder is installed on the top right side of the base plate, and the upper and lower ends of the hydraulic telescopic cylinder are hinged to the top plate and the base plate respectively.

[0010] Furthermore, both the first and second levels include a transparent housing and a bubble disposed within the transparent housing.

[0011] Furthermore, the rotating mechanism includes a turntable, a motor, and a transmission mechanism; the upper end of the turntable is fixedly connected to the base plate, the lower end of the turntable is rotatably connected to the base through a bearing, and the motor is connected to the turntable through the transmission mechanism.

[0012] Furthermore, the transmission mechanism includes a worm gear, a worm, and two mounting seats. The worm gear is fixedly sleeved on the periphery of the turntable, and the two mounting seats are fixedly mounted on the top of the base. The two ends of the worm are rotatably connected to the two mounting seats respectively, and one end of the worm passes through the mounting seat and is fixedly connected to the output end of the motor. The worm gear and the worm mesh with each other.

[0013] Furthermore, the lifting mechanism adopts a scissor-type hydraulic electric lifting platform.

[0014] Furthermore, the work platform has a disc structure, and a guardrail is provided around the top of the work platform.

[0015] Furthermore, the base is provided with multiple casters at its bottom and a handrail on one side of the base.

[0016] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0017] This utility model has a simple structure. By setting a horizontal adjustment mechanism, the tilt angle of the device can be adjusted, thereby ensuring that the working platform is in a horizontal state, which makes it highly practical. The horizontal state of the top plate can be determined by using a first and second level that are perpendicular to each other. When the bubble of the level is in the center of the transparent shell, it indicates that the top plate is horizontal along the length of the transparent shell. When both the first and second levels are horizontal, it indicates that the top plate is horizontal; otherwise, it indicates that the top plate is tilted. By setting up a rotating mechanism, a motor drives a worm gear to rotate, which in turn drives a turntable to rotate, so that the top plate rotates until the second level is horizontal, and the tilt direction of the ground can be determined. At this time, the top plate is tilted only in the test direction of the first level. By setting up an angle adjustment mechanism, when the second level is horizontal and the first level is tilted, the tilt angle of the top plate can be adjusted by adjusting the length of the hydraulic telescopic cylinder. At this time, the tilt state of the first level can be changed while the tilt state of the second level remains unchanged, so that both the first and second levels are horizontal, that is, the top plate is in a completely horizontal state, ensuring that the device can work stably. This invention effectively solves the problem in the prior art where uneven ground causes the device's center of gravity to shift, making it prone to tipping over, thus improving the device's safety.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to Figures 1 to 4This embodiment provides a boiler furnace maintenance lifting platform device, including a base 1, a horizontal adjustment mechanism disposed on the top of the base 1, a lifting mechanism 2 disposed on the top of the horizontal adjustment mechanism, and a work platform 3 disposed on the top of the lifting mechanism 2.

[0025] The leveling mechanism includes a base plate 41, a rotating mechanism disposed at the bottom of the base plate 41, an angle adjusting mechanism disposed at the top of the base plate 41, and a top plate 42 disposed at the top of the angle adjusting mechanism. The base plate 41 is rotatably connected to the base 1 via the rotating mechanism. A first level 51 is disposed on the front side of the top plate 42, and a second level 52 is disposed on the right side of the top plate 42, that is, the first level 51 and the second level 52 are perpendicular to each other in the horizontal direction. The rotating mechanism is used to rotate the base plate 41 relative to the base 1; the angle adjusting mechanism is used to adjust the tilt angle of the top plate 42 relative to the base plate 41; the first level 51 and the second level 52 can be used to determine whether the top plate 42 is in a horizontal state. When both the first level 51 and the second level 52 are in a horizontal state, it indicates that the top plate 42 is in a horizontal state; otherwise, it indicates that the top plate 42 is tilted.

[0026] The angle adjustment mechanism includes a support base 61 and a hydraulic telescopic cylinder 62. The support base 61 is fixedly disposed on the top left side of the base plate 41, and its upper end is hinged to the top plate 42. The hydraulic telescopic cylinder 62 is disposed on the top right side of the base plate 41, and its upper and lower ends are hinged to the top plate 42 and the base plate 41, respectively. The tilt angle of the top plate 42 relative to the base plate 41 can be adjusted by adjusting the length of the hydraulic telescopic cylinder 62.

[0027] In this specific embodiment, both the first level 51 and the second level 52 include a transparent housing 53 and a bubble 54 disposed within the transparent housing 53. When the bubble 54 is located in the middle of the transparent housing 53, it indicates that the level is horizontal in the detection direction.

[0028] In this specific embodiment, the rotating mechanism includes a turntable 71, a motor 72, and a transmission mechanism. The upper end of the turntable 71 is fixedly connected to the base plate 41, and the lower end of the turntable 71 is rotatably connected to the base 1 via a bearing 73. The motor 72 is connected to the turntable 71 via the transmission mechanism. The transmission mechanism includes a worm gear 74, a worm 76, and two mounting seats 75. The worm gear 74 is fixedly sleeved on the periphery of the turntable 71, and the two mounting seats 75 are fixedly mounted on the top of the base 1. The two ends of the worm 76 are rotatably connected to the two mounting seats 75 respectively, and one end of the worm 76 passes through the mounting seat 75 and is fixedly connected to the output end of the motor 72. The worm gear 74 and the worm 76 mesh with each other. By using the motor 72 to drive the worm 76 to rotate, and the worm 76 then drives the worm gear 74 to rotate, the turntable 71 and the components on the top of the turntable 71 can rotate relative to the base 1.

[0029] In this specific embodiment, the lifting mechanism 2 adopts a scissor-type hydraulic electric lifting platform. The aforementioned scissor-type hydraulic electric lifting platform is prior art and will not be described in detail here. Other types of lifting structures in the prior art can also be used. During the lifting process, the platform is stable without tilting, and the lifting speed is stable.

[0030] In this specific embodiment, the working platform is a disc structure, and a guardrail 31 is provided around the top of the working platform. The disc structure is used in conjunction with the rotating mechanism, so that the use of the working platform is not affected no matter which angle the rotating mechanism rotates the turntable 71 to; the guardrail 31 serves a protective function to prevent workers from falling off the working platform 3.

[0031] In this specific embodiment, the base 1 is provided with a plurality of rollers 11 at its bottom, and a handrail 12 is provided on one side of the base 1. The rollers 11 facilitate the movement of the entire device, and the handrail 12 facilitates the movement of the device.

[0032] The working principle of this utility model is as follows:

[0033] The device is placed on a level surface by using a first level 51 and a second level 52. When both the first level 51 and the second level 52 show a level state, it indicates that the device is not tilted. When at least one of the first level 51 and the second level 52 shows a tilted state, it indicates that the device is tilted. In this case, the turntable 71 is first rotated by adjusting the motor 72 until the second level 52 shows a level state. At this time, the first level 51 will show a tilted state, indicating that the device is tilted only in the test direction of the first level 51. Subsequently, the extension and retraction of the hydraulic telescopic cylinder 62 is adjusted by the angle adjustment mechanism until the first level 51 also shows a level state. At this time, both the first level 51 and the second level 52 are in a level state, that is, the top plate 42 and all components above the top plate 42 are in a level state, effectively reducing the safety risks for workers standing on the work platform 3 to carry out construction.

[0034] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
