DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0016] like Figure 1 , Figure 2 As shown, an aerial work platform includes: a base plate 1 and a rotating plate 2.

[0017] A U-shaped groove 11 is provided on one side of the bottom plate 1, and guardrails 12 are provided on both sides and the bottom of the top of the bottom plate 1 corresponding to the U-shaped groove 11. The bottom plate 1 is arranged on a lifting device or an aerial work vehicle.

[0018] The rotating plate 2 is a C-shaped structure, and a semicircular groove 21 is opened on one side of the rotating plate 2. The rotating plate 2 is parallel to and rotatably arranged on the base plate 1. The trajectory of the rotating plate 2 and the base plate 1 being rotatably connected is greater than one-half of the outer circle length of the rotating plate 2 to prevent the rotating plate 2 from separating from the base plate 1. As a preferred embodiment, the trajectory of the rotating plate 2 and the base plate 1 being rotatably connected can be further made equal to three-quarters of the outer circle length of the rotating plate 2. The axis of the semicircular groove 21 is coaxially arranged with the axis of the U-shaped groove 11, and the widths of the semicircular groove 21 and the U-shaped groove 11 are both greater than the outer diameter of the rod body to be operated. An arc-shaped railing 22 is provided on the top of the rotating plate 2. The arc-shaped railing 22 has a notch on one side corresponding to the opening of the semicircular groove 21, and there is a predetermined interval between the outer side of the arc-shaped railing 22 and the guardrail 12 to facilitate the placement of equipment and accommodate operators.

[0019] like Figures 2 to 4 As shown, the use method is that before the work platform rises, the direction of the rotating plate 2 is adjusted by rotating so that the opening of the semicircular groove 21 is aligned with the opening direction of the U-shaped groove 11, and the operator and the equipment are placed in the interval between the outer side of the arc railing 22 and the guardrail 12 to prevent the personnel and equipment from falling. Move the lifting device or the aerial work vehicle to one side of the rod body to be operated, use the lifting device or the aerial work vehicle to raise the work platform to a predetermined position, and make the semicircular groove 21 and the U-shaped groove 11 stuck on the outer side of the rod body. Rotate the rotating plate 2 so that the semicircular groove 21 and the U-shaped groove 11 are arranged oppositely. At this time, a circular hole structure will be formed between the bottom of the semicircular groove 21 and the U-shaped groove 11, and the rod body is inside the circular hole. The rotating plate 2 and the bottom plate 1 will cover the surroundings of the rod body, so as to facilitate the operation of the equipment around the rod body, which not only improves the convenience and safety of aerial work, but also avoids the tedious process of repeatedly moving the lifting device or the aerial work vehicle. Although the middle section of the rotating plate 2 will be suspended outside the bottom plate 1 at this time, because the track of the rotating plate 2 and the bottom plate 1 is greater than half of the outer circle length of the rotating plate 2, the two ends of the rotating plate 2 corresponding to the semicircular groove 21 will still be connected to the bottom plate 1, thereby preventing the rotating plate 2 from falling off. And after the rotating plate 2 rotates, the arc-shaped railing 22 will also rotate to the side opposite to the guardrail 12. At this time, the operator and the equipment will automatically be in the area enclosed between the arc-shaped railing 22 and the guardrail 12, so that it is convenient to start the operation directly.

[0020] Preferably, Figure 1 , Figure 2 As shown, a countersunk hole 13 is provided on the top surface of the base plate 1 for rotatably setting the rotating plate 2. The countersunk hole 13 and the rotating plate 2 are both one-half to three-quarter circular structures. An arc-shaped pressure plate 14 is provided on the top surface of the base plate 1 corresponding to the edge of the countersunk hole 13 for limiting the position above the rotating plate 2. The arc-shaped pressure plate 14 is connected to the base plate 1 by screws to facilitate the disassembly and assembly of the rotating plate 2.

[0021] Preferably, Figure 1 , Figure 2 As shown, the rotating plate 2 is provided with a through hole 23, and the bottom plate 1 is provided with a positioning hole 15 used in conjunction with the through hole 23. When the semicircular groove 21 is aligned with the opening direction of the U-shaped groove 11, a positioning pin 3 is used to pass through the through hole 23 and the positioning hole 15 at the same time, which can prevent the rotating plate 2 from rotating at will during the process of lifting the working platform.

[0022] Preferably, Figure 1 As shown, two blocking rods 4 are vertically penetrated on both sides of the bottom of the bottom plate 1 corresponding to the U-shaped groove 11. When the semicircular groove 21 is aligned with the opening direction of the U-shaped groove 11, the blocking rod 4 is located below the rotating plate 2 to avoid affecting the rotation of the rotating plate 2; when the semicircular groove 21 and the U-shaped groove 11 are arranged relative to each other, the blocking rod 4 is moved upward to the top of the bottom plate 1, and the side surfaces of the two blocking rods 4 are respectively abutted against the inner walls on both sides of the semicircular groove 21, so as to prevent the rotating plate 2 from rotating during operation, so as to improve the safety during operation.

[0023] Further preferably, Figure 1 , Figure 3 As shown, a disc 41 is provided at the lower end of the baffle rod 4, and a pressure plate 42 is provided at the top of the baffle rod 4. The baffle rod 4 is rotatably arranged around an axis. When the top surface of the disc 41 contacts the bottom surface of the bottom plate 1, the bottom surface of the pressure plate 42 is higher than the top surface of the rotating plate 2. A groove 16 is provided on the top surface of the bottom plate 1 for accommodating the pressure plate 42. When the pressure plate 42 is located in the groove 16, the top surface of the pressure plate 42 is lower than the bottom surface of the rotating plate 2. After the above structure is set, during operation, not only can the baffle rod 4 be used to limit the rotation of the rotating plate 2, but also the pressure plate 42 can be moved to the top of the rotating plate 2 by rotating the baffle rod 4 to prevent the rotating plate 2 from tilting upward, so as to improve the connection stability between the rotating plate 2 and the bottom plate 1.

[0024] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
