Description

Technical Field

[0001] This invention relates to a gantry-type aerial maintenance platform, specifically a gantry-type aerial maintenance platform with a horizontally sliding upper platform. Background Technology

[0002] In places such as shopping malls and hospitals, except for the ground floor, the structure is generally designed with passageways on both sides and a central atrium.

[0003] In the above scenario, the existing technology generally involves rappelling down from the roof to perform maintenance on the top structure between the two passageways on the top floor. This has problems such as low work efficiency and poor flexibility. Summary of the Invention

[0004] This invention proposes a gantry-type high-altitude maintenance platform with a horizontally sliding upper platform. Its purpose is to overcome the aforementioned shortcomings of existing technologies and improve the efficiency and flexibility of maintenance work. The technical solution of this invention is a gantry-type high-altitude maintenance platform with a horizontally sliding upper platform. Its structure includes a bottom central support moving truss mechanism, a middle support truss mechanism, and an upper sliding platform truss mechanism. The bottom central support moving truss mechanism is generally a cuboid with no two long sides at the bottom. Four moving wheels (A-shaped) are installed at the four corners of the bottom of the bottom central support moving truss mechanism. The middle support truss mechanism, also a cuboid, is fixed to the top surface of the bottom central support moving truss mechanism. The upper sliding platform truss mechanism, which is generally flat, is slidably connected to the top surface of the middle support truss mechanism. In use, the entire structure is moved along the aisles on both sides using the A-shaped moving wheels to the area requiring work. Personnel first climb onto the top surface of the bottom central support moving truss mechanism, then climb over the middle support truss mechanism to the top surface of the upper sliding platform truss mechanism for maintenance. During operation, the upper sliding platform truss mechanism can be slid horizontally to adjust the work position.

[0005] Preferably, the bottom center support movable truss mechanism can be connected to the bottom side truss mechanism on both sides. The overall shape of the bottom side truss mechanism is the same as that of the bottom center support movable truss mechanism, or the overall shape of the bottom side truss mechanism is a cuboid. The cuboid shape has no long side and no high side on the connection surface with the bottom center support movable truss mechanism, and the opposite side has no long side at the bottom. Two B movable wheels are respectively provided at the two bottom corners of the bottom of the side.

[0006] Preferably, a ladder A is attached to the side of the bottom center support moving truss mechanism adjacent to the A moving wheel. The top surface of the bottom center support moving truss mechanism, which is not connected to the middle support truss mechanism, is covered with an A tread. Guardrails A are provided on both sides of the A tread. A tread B is covered on the top surface of the upper sliding platform truss mechanism. Guardrails B are provided on both sides of the B tread. Ladders B are attached to the sides of the middle support truss mechanism adjacent to the A tread. When the upper sliding platform truss mechanism is in its initial position relative to the middle support truss mechanism, a hinged plate is provided at the position opposite the B tread and the B ladder. One can climb onto the A tread via the A ladder, and the A guardrails improve safety. Then, one can climb onto the B tread via the B ladder and the hinged plate. The hinged plate can be closed during operation to prevent falls, and the B guardrails further enhance safety.

[0007] Preferably, a number of slide rail wheels are fixed on the top surface of the middle-layer support truss mechanism along the horizontal sliding direction of the upper-layer sliding platform truss mechanism, and the bottom of the upper-layer sliding platform truss mechanism is slidably connected to the slide rail wheels via slide rails. Guide wheel sets supporting the bottom of the upper-layer sliding platform truss mechanism are provided on the top surface of the middle-layer support truss mechanism on both sides of the slide rail wheels.

[0008] Preferably, the system also includes a winch, A guide wheels, B guide wheels, and hooks. The winch is positioned on the top surface of the bottom center support movable truss mechanism, which is located at opposite ends of the middle support truss mechanism. The hooks are fixed to both ends of the bottom surface of the upper sliding platform truss mechanism. A guide wheels are positioned on the inner sides of the top ends of the middle support truss mechanism, and a pair of B guide wheels are positioned at the center of the top of the middle support truss mechanism. The wire rope wound on the winch passes sequentially through the adjacent A guide wheels and B guide wheels before being hooked onto the hooks. When the upper sliding platform truss mechanism is moved horizontally, the winch on the opposite side at the endpoint is rotated to wind up the wire rope. The wire rope pulls the hooks, causing the upper sliding platform truss mechanism to slide horizontally towards the endpoint. The wire rope on the other side is automatically released from the winch.

[0009] Advantages of this invention: The structure is reasonably designed, the platform as a whole can move along the passageways on both sides, and the upper platform can slide horizontally, making it easy to adjust to the position that needs maintenance. Compared with slings, it can effectively improve the efficiency of maintenance work and improve work flexibility. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0017] like Figure 1 , 5 As shown, a gantry-type high-altitude maintenance platform with a horizontally sliding upper platform has a structure including a bottom central support moving truss mechanism 1, a middle support truss mechanism 2, and an upper sliding platform truss mechanism 3. The bottom central support moving truss mechanism 1 is a cuboid with no two long sides at the bottom. A moving wheel 11 is provided at each of the four corners of the bottom of the bottom central support moving truss mechanism 1. The middle support truss mechanism 2, which is a cuboid in shape, is fixed on the top surface of the bottom central support moving truss mechanism 1. The upper sliding platform truss mechanism 3, which is a flat plate in shape, is slidably connected to the top surface of the middle support truss mechanism 2.

[0018] During construction, such as Figure 2 As shown, firstly, a suitable bottom-level central support movable truss mechanism 1 is constructed on the top floor of the site, in the non-corridor section, based on the distance between the two side corridors. Figure 3 As shown, a middle-level supporting truss mechanism 2 is then constructed on the bottom-level central supporting movable truss mechanism 1, as follows. Figure 4 As shown, the upper sliding platform truss mechanism 3 is finally built on the middle supporting truss mechanism 2. When in use, the entire structure is moved along the passageways on both sides by the A moving wheels 11 to the area where construction is required. Personnel first climb to the top surface of the bottom center supporting moving truss mechanism 1, and then climb to the top surface of the upper sliding platform truss mechanism 3 through the middle supporting truss mechanism 2 for inspection. During the operation, the upper sliding platform truss mechanism 3 can be slid horizontally to adjust the construction position.

[0019] To improve the overall structural stability, the bottom center support moving truss mechanism 1 can be connected to the bottom side truss mechanism 4 on both sides. The bottom side truss mechanism 4 has the same overall shape as the bottom center support moving truss mechanism 1, or the bottom side truss mechanism 4 has a cuboid shape. The cuboid shape has no long side and no high side on the connection surface with the bottom center support moving truss mechanism 1, and the opposite side has no long side at the bottom. The two bottom corners of the opposite side are respectively provided with B moving wheels 41.

[0020] In the specific design, an A ladder 12 is attached to the side of the bottom center support moving truss mechanism 1 adjacent to the A moving wheel 11. The top surface of the bottom center support moving truss mechanism 1, which is not connected to the middle support truss mechanism 2, is covered with an A step 13. A guardrails 14 are provided on both sides of the A step 13. The top surface of the upper sliding platform truss mechanism 3 is covered with a B step 33. B guardrails 32 are provided on both sides of the B step 33. A B ladder 34 is attached to the two sides of the middle support truss mechanism 2 adjacent to the A step 13. When the upper sliding platform truss mechanism 3 is in the initial position relative to the middle support truss mechanism 2, an opening and closing plate 35 is provided at the position opposite to the B step 33 and the B ladder 34.

[0021] One can climb to step A 13 via ladder A 12. Guardrail A 14 can improve safety. Then one can climb to step B 33 via ladder B 34 and hinged plate 35. Hinges 35 can be closed during operation to prevent falls. Guardrail B 32 can improve safety.

[0022] As a sliding connection structure, a number of slide rail wheels 21 are fixed on the top surface of the middle support truss mechanism along the horizontal sliding direction of the upper sliding platform truss mechanism. The bottom of the upper sliding platform truss mechanism 3 is slidably connected to the slide rail wheels 21 through the slide rail 31. Guide wheel sets 22 supporting the bottom of the upper sliding platform truss mechanism 3 are provided on the top surface of the middle support truss mechanism on both sides of the slide rail wheels 21.

[0023] To drive the sliding of the upper sliding platform truss mechanism 3, it also includes a winch 51, A guide wheel 52, B guide wheel 53 and hook 54. The winch 51 is set on the top surface of the bottom center support moving truss mechanism 1 at both ends of the middle support truss mechanism 2. The hook 54 is fixed to both ends of the bottom surface of the upper sliding platform truss mechanism 3. The A guide wheel 52 is set on the inner side of the top two ends of the middle support truss mechanism 2. A pair of B guide wheels 53 are set at the top center of the middle support truss mechanism 2. The steel wire rope wound on the winch 51 passes through the A guide wheel 52 and B guide wheel 53 on the adjacent side in sequence and is then hooked on the hook 54.

[0024] When the upper sliding platform truss mechanism 3 is moved horizontally, the winch 51 on the opposite side at the end point is rotated to wind up the wire rope. The wire rope pulls the hook 54, thereby causing the upper sliding platform truss mechanism 3 to slide horizontally towards the end point. The wire rope on the other side will be automatically released from the winch 51.

[0025] As a specific embodiment, the bottom center support movable truss mechanism 1 has a cuboid shape with each side composed of a frame. Several frames or single-row frames are connected between the frames on the two long sides of the top surface of the cuboid. A movable wheel 11 is installed at the bottom of the frames on each high side of the cuboid. A ladder 12 is hung on the frames on the wide side of the top surface of the cuboid. A step 13 is hung between the frames on the two long sides of the top surface of the cuboid. A guardrail 14 is also installed on the frames on the two long sides of the top surface of the cuboid.

[0026] Each side of the cuboid of the middle-level support truss mechanism 2 is composed of a frame. The bottom center of the frame on the two long sides of the top surface of the cuboid is also fixed with a frame. The frame is connected to the frame on the four high sides of the cuboid and the frame on the two long sides of the top surface of the cuboid of the bottom center support moving truss mechanism 1. Several frames or single rows of frames are connected between the frames on the two long sides of the top surface of the cuboid. The slide rail wheel 21 and the guide wheel group 22 are installed on the frames on the two long sides of the top surface of the cuboid. The ladder 34 is hung on the frames on the two wide sides of the top surface of the cuboid.

[0027] The upper sliding platform truss mechanism 3 is a rectangle composed of I-beam frames. Several single-row frames are connected between the I-beam frames on the two long sides of the rectangle. Single-row frames are also connected between the centers of adjacent single-row frames or between single-row frames and adjacent I-beam frames. The slide rail 31 is installed at the bottom of the I-beam frames on the long sides of the rectangle. The B guardrail 32 is installed at the top of the I-beam frames on both long sides of the rectangle. The B step 33 is hung between the tops of the I-beam frames on both long sides of the rectangle.

[0028] The bottom side truss mechanism 4 is a cuboid in shape. When the cuboid has no long side or high side on the connection surface with the bottom center support movable truss mechanism 1, and the opposite side has no long side at the bottom, each side of the cuboid is composed of a frame. Several single rows of frames are connected between the frame on the long side of the top surface of the cuboid and the frame on the long side of the top surface of the adjacent bottom center support movable truss mechanism 1.

[0029] To improve structural stability, several diagonal braces are connected between the top long side frame of the bottom side truss mechanism 4 (a cuboid shape) and the top long side frame of the adjacent middle support truss mechanism 2 (a cuboid shape), and between the top long side frame of the bottom center support moving truss mechanism 1 (a cuboid shape) and the top long side frame of the opposite adjacent middle support truss mechanism 2 (a cuboid shape).

[0030] The winch 51 is installed on an independent vertical frame, the hook 54 is installed at the bottom center of the rectangular wide side of the upper sliding platform truss mechanism 3, the A guide wheel 52 is installed at the inner center of the rectangular wide side of the top surface of the middle support truss mechanism 2, and the B guide wheel 53 is installed at the top of the rectangular frame connected between the centers of the two long sides of the top surface of the middle support truss mechanism 2.

[0031] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
