Description

Technical Field

[0001] The invention relates to the technical field of building operating platforms, in particular to a steel structure high-altitude installation operating platform. Background Art

[0002] The high-altitude installation operation platform is usually made of metal materials, such as steel pipes, aluminum alloy pipes, steel plates, etc. The platform structure includes columns, beams, diagonal braces, platform surfaces, etc. On the upper part of the platform, there is usually an operation station for people to sit and work. There is a track at the bottom to facilitate the movement of the platform.

[0003] During construction, steel columns are usually used to build the main frame of the building.

However, most common operating platforms are constructed individually and it is difficult to splice them with adjacent operating platforms during the construction process. This phenomenon will limit the activity space of the workers on the operating platform, and the working environment is not stable enough, which reduces the efficiency and quality of high-altitude construction work.

Two square grooves 41 are provided inside the fixed plate 9 for the L-shaped rod 39 to be inserted into.

The servo motor 16 will drive the shaft body 2 15 and the bevel gear 2 14 to rotate at the same time, thereby driving the bevel gear 2 14 and the bevel gear 1 13 to transmit to each other, and drive the shaft body 1 7 and the auxiliary plate 8 to rotate downward; at the same time, the shaft body 1 7 will also drive the flat gear 18 to rotate, thereby driving the rack 19 to transmit to each other, and the rack 19 will push the side frame 4 to gradually move away from the frame body 1 until the auxiliary plate 8 rotates to coincide with the base plate 2, and the servo motor 16 stops rotating. The staff can insert the L-shaped rod 39 into the interior of the fixed plate 9 and the auxiliary plate 8, and rotate the bent part of the L-shaped rod 39 into the square groove 41, so that the fixed plate 9, the auxiliary plate 8 and the base plate 2 form a new stable operating platform.

[0024] According to the above embodiment, embodiment 2, Two limit rods 11 are further provided inside the frame 1. A docking unit 12 is provided inside the frame 1 to drive the limit rods 11 to extend outward. The expansion unit 10 and the docking unit 12 cooperate with each other to enable two adjacent frames 1 to perform high-altitude docking operations. The docking unit 12 includes an inclined block 23 located on one side of the insertion rod 6, the side surface of the inclined block 23 is fixedly connected to the insertion rod 6, the end of the limit rod 11 is provided with a protrusion 24 and fixedly connected thereto, the outer walls of the two limit rods 11 are provided with a connecting plate 25 and are fixedly connected thereto, the outside of the two limit rods 11 are provided with a spring 26, the outer wall of the limit rod 11 is also provided with a fixing plate 27 and is slidably connected thereto, the two ends of the spring 26 are respectively fixedly connected to the fixing plate 27 and the connecting plate 25, and the wall of the frame 1 is provided with a socket 28 for the limit rod 11 to slide. When the inclined block 23 slides with the insertion rod 6, the inclined area of ​​the inclined block 23 resists the outer edge of the protrusion 24, thereby driving the two limit rods 11 to gradually extend from the inside of the frame 1 for subsequent docking work, and the elastic force of the spring 26 under normal conditions pushes the end of the limit rod 11 to coincide with the inner wall surface of the frame 1, so as to facilitate the position adjustment of the two limit rods 11.

[0025] Furthermore, the outer wall of the fixing plate 27 is provided with a fixing groove 29 and fixedly connected thereto, the fixing plate 27 slides freely inside the fixing groove 29, the fixing plate 27 is slidably connected to the fixing groove 29, a connecting block 30 is provided above the protrusion 24 and fixedly connected thereto, the interior of the connecting block 30 is rotatably connected with a rotating bar 31 through a rotating shaft, a U-shaped frame 1 32 is provided above the frame 1 for the rotating bar 31 to be inserted, a U-shaped frame 2 33 having a groove width equal to that of the U-shaped frame 1 32 is also provided above the frame 1, and the U-shaped frame 1 32 and the U-shaped frame 31 are connected to each other. The bottom of the second frame 33 is fixedly connected to the frame body 1, the rotating bar 31 is L-shaped, a U-shaped frame 34 is provided above the U-shaped frame 1 32, the bottom of the U-shaped frame 34 is fixedly connected to the frame body 1, a stopper 35 is provided inside the U-shaped frame 34 and is slidably connected thereto, a spring 2 36 is provided above the stopper 35, a fixing box 37 is provided outside the spring 2 36, both ends of the spring 2 36 are fixedly connected to the stopper 35 and the fixing box 37 respectively, and the fixing box 37 is located above the U-shaped frame 34 and is fixedly connected thereto; During the sliding process of the rotating bar 31 inside the U-shaped frame 32, the end of the rotating bar 31 contacts the inclined portion of the stop block 35, thereby driving the stop block 35 to rise upward. A pull rod 38 is provided above the stop block 35 and is fixedly connected thereto. The pull rod 38 passes through the fixed box 37 and is slidably connected thereto. The staff can drive the stop block 35 to rise upward by pulling the pull rod 38 to return the rotating bar 31 to its original position.

[0026] When it is necessary to dock different adjacent frames 1, the rotating bar 31 in the adjacent frame 1 can be rotated upward first to disengage it from the groove of the U-shaped frame 1 32. At this time, the rotating bar 31 drives the connecting block 30, the protrusion 24 and the two limiting rods 11 to move inside the frame 1 until the rotating bar 31 moves to align with the notch of the U-shaped frame 2 33. At this time, the rotating bar 31 is rotated again into the notch of the U-shaped frame 2 33 and is limited. In this state, there is no limiting rod 11 behind the two insertion holes 28, so that the limiting rod 11 inside the other frame 1 can be inserted. At this time, the servo motor 16 inside the frame 1 is started again, so that the insertion rod 26 drives the inclined block 23 to move until the inclined portion of the inclined block 23 is in contact with the protrusion 24, and the two limit rods 11 will gradually extend from the inside of the frame 1 and be inserted into the two sockets 28 inside the other frame 1. During this process, the protruding portion of the rotating bar 31 will be in contact with the inclined portion of the stop block 35, and drive the stop block 35 to rise inside the fixed box 37 until the end of the rotating bar 31 completely passes the stop block 35, and the elastic force of the spring 2 36 will drive the stop block 35 to drop to its original position. Under the elastic force of the spring 1 26, the end of the rotating bar 31 will be in contact with the flat area of ​​the stop block 35, thereby limiting the extended position of the rotating bar 31 and the limit rod 11, and finally completing the docking of the two adjacent frames 1. The two operating platforms can be stably docked in a high-altitude environment. At the same time, the expansion unit 10 also expands the activity space of the operating platform, which is suitable for high-altitude operations with wider walls, and further improves the work efficiency and quality of high-altitude operations.
