DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-6 A portable aerial work platform is shown, comprising a cross bar 1 and a vertical bar 11 overlapped orthogonally with the cross bar 1, and also comprising a base plate 2, on which a suspension arm 21 is rotatably provided, and on which a hook 22 is provided for buckling with the cross bar 1; the base plate 2 is also rotatably provided with a support assembly for abutting against the vertical bar 11 and a tension assembly rotatably provided on the support assembly for tensioning and locking with the vertical bar 11. During the template erection work, the outer side of the template will form an enclosed fixed structure with the cross bar 1 and the vertical bar 11 to ensure the stability of the template combination, and then the template will be tied to the cross bar 1 or the vertical bar 11 layer by layer for splicing. When the template splicing height is too high, it is necessary to build an aerial work platform, and the conventional platform construction is to set up scaffolding on the outside, but this construction method is not applicable in some environments, such as The template is constructed on a foundation table with an edge, and the edge height is relatively large. At this time, erecting scaffolding on the lowest level will consume a lot of manpower and material resources, resulting in a longer construction period. Therefore, this scheme designs a portable platform structure, which utilizes the platform 2 as a platform for workers to walk on, and utilizes the suspension arm 21 provided on the platform 2 to be hung between the cross bar 1, so that the platform 2 is initially suspended at the required working surface height, and then the support assembly provided at the bottom end of the platform 2 is abutted against the vertical pole 11 to form a support structure at the bottom. Since the support assembly is mobile with the platform 2, it cooperates with the pulling assembly to further pull and lock the pulling assembly with the vertical pole 11, thereby forming a stable working surface, which is convenient for workers to quickly establish an aerial work platform and speed up construction.

[0026] In one embodiment, the support assembly includes two groups of inclined support arms 3 rotatably arranged on both sides of the base plate 2, and a support head 31 rotatably arranged at one end of the inclined support arm 3 away from the base plate 2. The support head 31 is provided with an arc groove adapted to the surface of the vertical pole 11, and the surface of the arc groove is provided with a rubber pad 32. Due to the movable connection between the base plate 2 and the suspension arm 21, when a worker stands on the base plate 2, the base plate 2 will tend to rotate downward. At this time, the inclined support arm 3 is used to construct a support structure with the vertical pole 11, so as to stabilize the base plate 2 and prevent it from flipping over. The setting on the support head 31 is used to form a matching abutment surface with the vertical pole 11 through the arc groove on the surface, and then the rubber pad 32 is used to enhance the friction between the surface of the vertical pole 11, thereby achieving a high degree of support stability.

[0027] In one embodiment, the tension assembly includes a secondary support arm rod 4 rotatably connected to the diagonal support arm 3, a first screw rod 41 movably connected to the secondary support arm rod 4, a fastener 42 arranged on the first screw rod 41, and a nut 43 threadedly connected to the first screw rod 41 and located on the side of the secondary support arm rod 4 away from the fastener 42. A cylindrical clamping joint 5 is also provided on the secondary support arm rod 4, a hook 51 is provided on the support plate 2, and a clamping groove 52 adapted to be clamped with the clamping joint 5 is provided on the hook 51. Since the diagonal support arm 3 and the support plate 2 are in a movable connection structure, although the lower end thereof forms an abutment structure with the vertical rod 11 through the abutment head 31, in order to prevent the two from being in contact with each other, the secondary support arm 4 is provided with a cylindrical clamping joint 5, and a hook 51 is provided on the support plate 2. The hook 51 is provided with a clamping groove 52 adapted to be clamped with the clamping joint 5. Since the diagonal support arm 3 and the support plate 2 are in a movable connection structure, although the lower end thereof forms an abutment structure with the vertical rod 11 through the abutment head 31, in order to prevent the two from being in contact with each other, the secondary support arm 4 is provided with a cylindrical clamping joint 5. In case of relative sliding caused by insufficient friction, a pulling component is further provided, that is, by rotating it to be parallel to the vertical pole 11, and buckling the fastener 42 at the upper end thereof with the vertical pole 11, and then rotating the nut 43, the secondary support arm rod 4 and the vertical pole 11 are pulled and locked, so that a stable integral structure is formed between the vertical pole 11 and the base plate 2, and at the same time, the clamping joint 5 provided on the secondary support arm rod 4 is clamped with the clamping groove 52 on the clamping hook 51, so that the secondary support arm rod 4 forms an additional supporting structure for the base plate 2, and also ensures that the angle between the diagonal support arm 3 and the base plate 2 is completely fixed, and the overall structure has a high degree of stability.

[0028] In one embodiment, the upper surface of the base plate 2 is also rotatably provided with side baffles 6 that flip to both sides and a rear baffle 61 that flips forward and backward. The side baffles 6 are provided with convex plates 62, and the rear baffles 61 are provided with side ear plates 63. The convex plates 62 and the side ear plates 63 are connected and fixed by fixing bolts 64. The side baffles 6 and the rear baffle 61 are rotated to form a fence, and then the fixing bolts 64 are used to pass through the convex plates 62 and the side ear plates 63 to fix them, thereby forming a protective structure on the side of the base plate 2 to ensure the safety of construction personnel's activities on the base plate 2.

[0029] In one embodiment, in order to further enhance the buckling stability between the suspension arm 21 and the cross bar 1, a second screw rod 7 is threadedly connected to the hook 22. When the suspension arm 21 is hooked with the cross bar 1, the second screw rod 7 is rotated to make it movable and engage with the outer surface of the suspension arm 21, and then cooperate with the hook 22 to form a completely closed structure, so that the suspension arm 21 will not be separated from the cross bar 1.

[0030] In one embodiment, in order to ensure the safety of construction workers during high-altitude operations, a belt slide bar 8 for hanging a safety belt is further provided between the suspension arms 21. The minimum preset distance between the belt slide bar 8 and the base plate 2 is two meters so that it meets the hanging height of the safety belt. According to the requirements of the high-altitude operation specifications, when the workers stand on the base plate 2 for construction, they need to hang the safety belt on a stable structure higher than the head to prevent the danger of falling. Usually, the safety belt is buckled on the cross bar 1 higher than the head height of the construction workers. However, since the vertical poles 11 are evenly arranged between the cross bars 1, when the workers walk, the safety belt needs to be temporarily unhooked from the cross bar 1 after sliding to the intersection of the vertical poles 11 and the cross bar 1, and then moved and re-buckled. The belt slide bar 8 can ensure the full sliding requirement of the safety belt, thereby avoiding the risk of temporarily disconnecting and buckling, and further improving the convenience and safety of construction.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
