[0002] Aerial work refers to construction operations carried out at heights based on a certain position. In the prior art, devices such as hanging baskets are usually used for aerial work. However, the hanging basket device can only adjust the height and cannot well cope with horizontal construction operations. Currently, multiple hanging basket devices are usually erected to handle horizontal operations. But in the face of some special occasions, such as trestles, erecting multiple hanging basket devices only increases the labor intensity of workers and reduces the construction efficiency. At the same time, the hanging basket device or some movable platforms with a certain height cannot stably lift materials to the required position, making it difficult to transfer construction materials. Summary of the Invention

[0003] The present invention provides a cross-girder type aerial work platform, which solves the problems in the related art that erecting multiple hanging basket devices to handle special occasions such as trestles only increases the labor intensity of workers and reduces the construction efficiency, and at the same time, the hanging basket device or some movable platforms with a certain height cannot stably and quickly transfer construction materials.

[0004] The technical solution of the present invention is as follows:

[0005] A cross-girder type aerial work platform, comprising

[0006] A main frame with an opening,

[0007] Side frames, with side frames provided at both ends of the main frame. A sliding space is formed between the side frames and the main frame. The opening communicates with the sliding space and is located on one side of the side frame. The sliding space is used for passing through a trestle.

[0008] A traveling member, provided on the main frame and located within the sliding space.

[0009] A lifting member, provided on the main frame. The lifting member is used to lift materials into the sliding space through the opening.

[0010] As a further technical solution, the side frames are provided at both ends of the main frame with adjustable positions. The main frame includes

[0011] A first main frame and a second main frame. The second main frame is provided at both ends of the first main frame with adjustable positions. The side frames are provided on the second main frame with adjustable positions. The direction of position adjustment of the second main frame and the direction of position adjustment of the side frames are perpendicular to each other. A sliding space is formed among the first main frame, the second main frame, and the side frames. The second main frame has the opening.

[0012] As a further technical solution, it further includes

[0013] a first support member, which is arranged at the bottom of the side frame,

[0014] a plurality of second support members, which are spaced apart on the side frame and are located above the first support member, and the lengths of the plurality of second support members are all smaller than the length of the side frame,

[0015] a ladder member, which is arranged on the side frame, and the first support member and the second support member are both located on one side of the ladder member.

[0016] As a further technical solution, both the first support member and the second support member include

[0017] a bottom plate, which is arranged on the side frame,

[0018] a connecting support member, which is arranged on the bottom plate,

[0019] a support plate, which is ball-jointedly arranged on the connecting support member and is located above the bottom plate,

[0020] a connecting driving member, which is arranged on the bottom plate and connects the support plate.

[0021] As a further technical solution, the connecting driving member includes

[0022] a driving rod, which is rotatably arranged on the bottom plate,

[0023] a connecting rod, one end of which is ball-jointedly arranged on the driving rod and the other end of which is ball-jointedly arranged on the support plate.

[0024] As a further technical solution, there are a plurality of the connecting driving members, and the plurality of connecting driving members are spaced apart.

[0025] As a further technical solution, the connecting support member is a telescopic member.

[0026] The working principle and beneficial effects of the present invention are as follows:

[0027] In the present invention, the hanging basket device can only adjust the height position for high-altitude operation, and cannot quickly and comprehensively operate in special occasions such as trestles. Moreover, further using the hanging basket device cannot stably lift the materials to the required position. To solve the above problems, the inventor designs a cross-girder type high-altitude operation platform;

[0028] At present, the hanging basket device used for working at height cannot well adapt to the trestle bridge that connects two buildings and is located at a high altitude. This is because the hanging basket device can only adjust the vertical height position, while the trestle bridge is usually horizontal or inclined. The hanging basket device cannot conveniently and comprehensively construct the trestle bridge. Therefore, the inventor designed a cross-gate frame form that can fully cover the trestle bridge. It is composed of a main frame and side frames at both ends of the main frame. The sliding space formed between the main frame and the side frames can just pass through the trestle bridge. The cross-gate frame form allows workers to stand around the trestle bridge, facilitating the construction of the trestle bridge. At the same time, the main body of the cross-gate frame can also be stably moved on the trestle bridge driven by a traveling member. When it moves to the construction position, the traveling member can be controlled to lock to further stabilize the construction position of the workers.

[0029] Since the cross-gate structure is composed of a main frame and side frames at both ends of the main frame, workers can stand on the side frames or the main frame to operate on the outer wall of the trestle bridge. During the construction process, the transfer of materials may be required. Lifting materials from the ground to the frame or lowering them from the frame to the ground usually requires workers to use fixed pulleys and ropes, etc., which is inconvenient for transferring materials. The inventor designed that the main frame has an opening that communicates with the sliding space. By using a lifting member, it can lift the materials through the opening into the sliding space. And the opening is located on one side of the side frame. The materials can be lifted to one side of the side frame under the action of the lifting member, facilitating the workers on the side frame to receive the construction materials, or lifted to the main frame through the opening to achieve stable material transfer. Moreover, the lifting member can also be set in various moving forms to further adapt to the transfer of materials. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0040] As Figures 1 to 7 shown, this embodiment proposes

[0041] In this embodiment, a cross-gate type aerial work platform includes

[0042] a main frame 1 with an opening 2,

[0043] side frames 3 are provided at both ends of the main frame 1. A sliding space 4 is formed between the side frames 3 and the main frame 1. The opening 2 communicates with the sliding space 4 and is located on one side of the side frames 3. The sliding space 4 is used for passing a trestle bridge.

[0044] a traveling member 5 is arranged on the main frame 1 and is located in the sliding space 4.

[0045] a lifting member 6 is arranged on the main frame 1. The lifting member 6 is used to lift materials into the sliding space 4 through the opening 2.

[0046] In this embodiment, the hanging basket device can only adjust the height position for aerial work and cannot quickly and comprehensively operate in special occasions such as trestle bridges. Moreover, further using the hanging basket device cannot stably lift materials to the required position. To solve the above problems, the inventor designed a cross-gate type aerial work platform;

[0047] At present, the hanging basket device used for working at heights cannot well adapt to the trestle bridge that connects two buildings and is located at high altitude. This is because the hanging basket device can only adjust the vertical height position, while the trestle bridge is usually horizontal or diagonal. The hanging basket device cannot conveniently and comprehensively construct the trestle bridge. Therefore, the inventor designed a cross-gate frame form that can fully cover the trestle bridge. It is composed of a main frame 1 and side frames 3 at both ends of the main frame 1. The sliding space 4 formed between the main frame 1 and the side frames 3 can just pass through the trestle bridge. The cross-gate frame form allows workers to stand around the trestle bridge, facilitating the construction of the trestle bridge. At the same time, the cross-gate frame body can also be stably moved on the trestle bridge driven by a driving part 5. When it moves to the construction position, the driving part 5 can be controlled to lock to further stabilize the construction position of the workers.

[0048] Since the cross-gate structure is composed of a main frame 1 and side frames 3 at both ends of the main frame 1, workers can stand on the side frames 3 or the main frame 1 to operate on the outer wall of the trestle bridge. During the construction process, material transfer may be required, lifting materials from the ground to the frame or lowering them from the frame to the ground. Usually, workers use fixed pulleys and ropes to complete this, which is inconvenient for material transfer. The inventor designed that the main frame 1 has an opening 2, and the opening 2 communicates with the sliding space 4. By using a lifting part 6, it can lift materials into the sliding space 4 through the opening 2. And the opening 2 is located on one side of the side frame 3, so that the materials can be lifted to one side of the side frame 3 under the action of the lifting part 6, or lifted onto the main frame 1 through the opening 2, realizing stable material transfer. And the lifting part 6 can also be set in a variety of moving forms to further adapt to material transfer.

[0049] Furthermore, the side frames 3 are arranged at both ends of the main frame 1 with adjustable positions, and the main frame 1 includes

[0050] a first main frame 7 and a second main frame 8. The second main frames 8 are arranged at both ends of the first main frame 7 with adjustable positions. The side frames 3 are arranged on the second main frames 8 with adjustable positions. The position adjustment directions of the second main frames 8 and the side frames 3 are perpendicular to each other. And the sliding space 4 is formed between the first main frame 7, the second main frames 8 and the side frames 3. The second main frame 8 has the opening 2.

[0051] In this embodiment, in order to adapt to the size specifications of different forms of trestle bridges and prevent the cross-gate structure from not fully covering the trestle bridge, the inventor designed that the side frames 3 are arranged on the second main frames 8 with adjustable positions, and the second main frames 8 are arranged on the first main frame 7 with adjustable positions, and the position adjustable directions of the two workpieces are perpendicular, in order to adapt to adjusting the height and width of the cross-gate structure. And in order to facilitate the opening 2 to be close to the side frame 3 so that materials can be conveniently transferred to the side frame 3, the inventor designed that the second main frame 8 close to the side frame 3 has the opening 2.

[0052] Furthermore, it further includes

[0053] The first support member 9 is disposed at the bottom of the side frame 3.

[0054] There are several second support members 10, and the several second support members 10 are spaced apart on the side frame 3 and located above the first support member 9. The lengths of the several second support members 10 are all smaller than the length of the side frame 3.

[0055] The ladder member 11 is disposed on the side frame 3, and the first support member 9 and the second support member 10 are both located on one side of the ladder member 11.

[0056] In this embodiment, the inventor designs to add support members to the side frame 3. Since there are multiple support members, they can be divided into multiple layers of platforms. Workers can stand on platforms at different heights to construct the trestle, which can speed up the progress and is more convenient for constructing different positions of the trestle. The first support member 9 is disposed at the bottom of the side frame 3, which is convenient for construction and can ensure the safety of workers. The several second support members 10 separate multiple platforms at different heights. At the same time, the length of the second support member 10 is smaller than the length of the side frame 3 to facilitate the connection between multiple platforms and the transfer of workers between different platforms. The ladder member 11 is located on one side of the first support member 9 and the second support member 10, which can facilitate the transfer of workers between multiple platforms. The ladder member 11 is located inside the frame and also has safety.

[0057] Furthermore, both the first support member 9 and the second support member 10 include

[0058] A bottom plate 12 is disposed on the side frame 3.

[0059] A connecting support member 13 is disposed on the bottom plate 12.

[0060] A support plate 14 is ball-jointedly disposed on the connecting support member 13 and located above the bottom plate 12.

[0061] A connecting driving member 15 is disposed on the bottom plate 12 and connects the support plate 14.

[0062] In this embodiment, under the action of the traveling member 5, the frame platform moves on the top of the trestle. Due to reasons such as the overall trestle not being completely horizontal during the preliminary construction or after being used for a period of time, the entire frame moving on it is inclined, and the personnel standing on the frame for construction are also inclined and cannot perform operations well. For operations on the top of the trestle, workers can directly perform them on the trestle or on the top of the frame without the need to adjust its angle. However, the angles of multiple support members on the side frame 3 need to be adjusted to ensure convenient construction for workers. The existing angle adjustment form usually achieves it by adjusting the hole positions. This form cannot adjust the angle in a timely manner during construction or other situations. To further facilitate the angle adjustment of the support members, the inventor designs that the first support member 9 and the second support member 10 both include a bottom plate 12, a connecting support member 13, a support plate 14, and a connecting driving member 15; the setting of the bottom plate 12 plays a role in stable support, the connecting support member 13 plays a supporting role, and the support plate 14 is the workpiece for angle adjustment. Workers will stand on the support plate 14, and the two are connected by the connecting support member 13 arranged at the center of the bottom plate 12. Since the connecting support member 13 is at the center position of the bottom plate 12 and to prevent the support plate 14 from being unable to adjust the angle, the inventor designs that the support plate 14 is ball-jointedly arranged on the connecting support member 13; to drive and adjust the angle of the support plate 14, the inventor uses the connecting driving member 15 on the bottom plate 12 to drive it to adjust the angle by connecting the support plate 14.

[0063] Further, the connecting driving member 15 includes

[0064] a driving rod 16, rotatably arranged on the bottom plate 12,

[0065] a connecting rod 17, one end of which is ball-jointedly arranged on the driving rod 16, and the other end of which is ball-jointedly arranged on the support plate 14.

[0066] In this embodiment, to facilitate the connecting driving member 15 to drive and adjust the angle of the support plate 14, the inventor uses the driving form of rotating the driving rod 16. And since both ends of the connecting rod 17 are ball-jointedly connected to the driving rod 16 and the support plate 14 respectively, the ball-joint form makes the movement more flexible and can also play a certain role in supporting and stabilizing.

[0067] Further, there are several connecting driving members 15, and several said connecting driving members 15 are arranged at intervals.

[0068] In this embodiment, to more comprehensively control the angular swing of the support plate 14, the inventor uses several connecting driving members 15 arranged at intervals, and several connecting driving members 15 can be arranged at the corner positions of the bottom plate 12.

[0069] Further, the connecting support member 13 is a telescopic member.

[0070] In this embodiment, by designing the connecting support member 13 as a telescopic member, the limiting position of the angle adjustment of the support plate 14 can be controlled. When the support plate 14 moves away from the bottom plate 12, the support plate 14 can make a larger angle adjustment. When the support plate 14 moves closer to the bottom plate 12, the support plate 14 can only make a smaller angle adjustment.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
