[0002] In the existing technology, the crane beam is an important system in the steel structure factory. It has many installed components. The main component is the crane beam. Usually, the size varies greatly according to the span and bearing capacity. The length is generally 12-18m and the height is 1.5-2m. There are crane beams on both sides of the steel column or one side is an auxiliary truss. The center distance between the two crane beams with crane beams on both sides is generally 2m, and the center distance between the crane beam on one side and the auxiliary truss on the other side is generally 1.6m. The upper and lower flange plates between the two crane beams are connected by steel components to form a closed rectangular frame. At the same time, multiple vertical scissor braces are added at the rectangular cross section. These components are installed in the horizontal position and are called horizontal braces, and those installed in the vertical position are called scissor braces. These large and small components eventually form a stable rectangular structure as a whole. The installation height of the crane beam is very high, usually at 2 / 3 of the total height of the plant, generally 10-14m, and the lower part is completely suspended. At the same time, there are many components that need to be installed. After being connected by bolts, welding reinforcement is required. Therefore, it is difficult to install the horizontal and vertical supports between the crane beams: first, the plant is still under construction, the ground has not been formed, and the vertical lift cannot be used; when using a small articulated boom truck as an operating vehicle, the articulated boom truck cannot reach the operating position because the installation components are between the two crane beams.

[0035] In this embodiment, the adjustment frame 2 further includes a limit frame 22 , which is disposed outside the slide bar 21 to fix the first fixing wheel 31 and limit the movement of the first adjustment wheel 41 .

[0036] In this embodiment, the end of the slide bar 21 away from the fixing plate 33 is connected to the limit frame 22, and the limit frame 22 and the fixing plate 33 are vertically connected to form an L shape.

One end of the second connecting rod 133 is provided with a thread adapted to the adjusting sleeve 132, and the other end is connected to the guardrail 12. The rotation direction of the surface threads of the first connecting rod 131 and the second connecting rod 133 is opposite. Construction personnel can adjust the length of the connecting assembly 13 by rotating the adjusting sleeve 132 on the working platform 1, and the handle can be optimally set on the adjusting sleeve 132 to facilitate the rotation operation.

[0039] When the movable clamping mechanism is required to clamp the beam 8, the sliding adjustment wheel assembly 4 is used to clamp the beam 8 and fix it through the positioning member 43;

[0040] When a person is on the working platform 1, the ratchet drive assembly 6 and the chain 5 can be controlled to drive the working platform 1 to move along the length direction of the chain 5 to the expected construction position, and the longitudinal height of the base 11 can be adjusted by adjusting the extension and retraction of the connecting assembly 13.

[0042] Select a working platform 1 of appropriate size according to the center distance between the two traveling beams, install each movable clamping mechanism on the corresponding traveling beam, slide the adjusting wheel assembly 4 so that it and the fixed wheel assembly 3 clamp the flange plates on both sides of the beam 8 respectively, and fix the distance between the adjusting wheel assembly 4 and the fixed wheel assembly 3 by the positioning piece 43; fix the chain 5 at both ends of the traveling beam, and fix it on the steel structure column to adjust the movement.

[0043] During construction, the personnel can first hang the safety rope 9, and then hang the safety belt on the safety rope 9. The combination of the safety belt and the safety rope 9 and the working platform for the steel structure workshop are two different systems to improve the working safety of the construction personnel.

[0044] When the working height changes, the personnel can adjust the longitudinal height on the working platform 1. In this embodiment, the longitudinal height of the base 11 can be quickly adjusted by rotating the adjusting sleeve 132; when the working position needs to be moved forward or backward, the ratchet drive assembly 6 can be controlled to drive the working platform 1 forward and backward along the length direction of the chain 5 through transmission with the chain 5; when the working platform 1 moves to the appropriate working position, the lifting mechanism 7, that is, the winch, can be used to lift the construction components to be installed: such as horizontal braces, vertical scissors braces, etc. onto the working platform 1 for rapid installation.

[0045] The working platform of the utility model used for steel structure workshops can safely and conveniently carry out the installation of horizontal braces or vertical scissors braces between traveling beams of different specifications, providing a safe and stable working platform for construction personnel, while reducing the operating costs of automobile cranes, articulated arm trucks, etc. It can move horizontally back and forth to carry out multi-point operations, and can also move vertically for rapid adjustment, thereby adapting to different working environments. It is easy to operate, has high construction efficiency, reduces the time of high-altitude operations, and facilitates the transportation of construction components.
