For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances. Specific embodiments:
[0027] Such as Figure 1 and Figure 2As shown in the figure, the present application provides a mobile platform, which includes a mobile frame 1. A platform board 2 and a guardrail 3 are fixedly arranged on the mobile frame 1. The guardrail 3 surrounds the periphery of the platform board 2. A staircase frame 4 is arranged on one side of the platform board 2. An opening is provided on the guardrail 3 for the staff to climb from the staircase frame 4 onto the platform board 2. The upper end of the staircase frame 4 is movably connected to the mobile frame 1. A support member 5 is arranged at the lower part of the mobile frame 1 to support the lower part of the staircase frame 4. A plurality of rollers 6 are arranged at the bottom of the mobile frame 1. A plurality of threaded through holes are provided on the mobile frame 1, and fixing bolts 7 are threadedly connected in the threaded through holes. After the staff moves the mobile frame 1 to the required position, by screwing the fixing bolts 7 to make the fixing bolts 7 contact the bottom surface, the mobile frame 1 is supported and fixed to prevent the mobile frame 1 from shifting. Then, the staff climbs onto the platform board 2 through the staircase frame 4 to perform operations. Compared with using ladders and stools as footrests in the prior art, it has high safety and good convenience.
[0028] As Figure 2 and Figure 3 shown in the figure, pulleys 41 are rotatably installed on both sides of the upper end of the staircase frame 4. A guiding groove 11 adapted to the pulleys 41 is provided on the mobile frame 1. An arc portion 12 adapted to the pulleys 41 is provided at one end of the guiding groove 11 close to the staircase frame 4. The staircase frame 4 is slidably connected to the mobile frame 1 through the pulleys 41. Specifically, in the initial state, the pulleys 41 of the staircase frame 4 are located at one end of the guiding groove 11 away from the arc portion 12. When the staircase frame 4 is needed, the staircase frame 4 is pulled to make the pulleys 41 of the staircase frame 4 approach the arc portion 12, and the pulleys 41 slide into the arc portion 12. Then, the lower part of the staircase frame 4 is lowered, and the staff can climb onto the platform board 2 through the staircase frame 4 to perform operations. When the entire device is used up, the upper part of the staircase frame 4 is gently lifted to make the pulleys 41 move from the arc portion 12 to the guiding groove 11, and then the staircase frame 4 is pushed to make the pulleys 41 return to the initial position, and the staircase frame 4 can be folded and stored to reduce the occupation of space.
[0029] As Figures 1-3 shown in the figure, one end of the support member 5 is fixedly connected to the mobile frame 1, and the end of the support member 5 away from the mobile frame 1 abuts against the staircase frame 4. When the pulleys 41 of the staircase frame 4 slide into the arc portion 12 and the lower part of the staircase frame 4 abuts against the support member 5, a triangle is formed among the skeleton of the staircase frame 4, the support member 5 and the mobile frame 1, so that the staircase frame 4 is stably supported.
[0030] As Figure 1 and Figure 4 shown in the figure, a limiting groove 51 is provided at the end of the support member 5 away from the mobile frame 1. The skeleton of the staircase frame 4 is located in the limiting groove 51. When the lower part of the staircase frame 4 abuts against the support member 5, the limiting groove 51 plays a role in limiting the skeleton of the staircase frame 4, making the placement of the staircase frame 4 more stable.
[0031] As Figure 1As shown, anti-slip patterns 21 are provided on the platform plate 2 to prevent the staff from slipping when working on the platform plate 2.
[0032] As Figure 1 shown, four rollers 6 are provided, and the four rollers 6 are respectively arranged at the four corners of the bottom of the moving frame 1, so that the moving frame 1 can move stably. Four threaded through holes are provided, and the four threaded through holes are symmetrically arranged at the bottom of the moving frame 1. By turning the fixing bolts 7 in the threaded through holes, the ends of the four fixing bolts 7 are abutted against the bottom surface, and the moving frame 1 can be fixed to prevent the moving frame 1 from displacing, thereby improving the operation safety of the staff.
[0033] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
