Description

Technical Field

[0001] This utility model relates to the field of mobile support technology, specifically a mobile support. Background Technology

[0002] In Inner Mongolia, high-altitude operations in logistics mainly involve hooking operations, requiring personnel to climb onto semi-trailers. Common semi-trailers are mostly flatbed and stake-lift trailers. For flatbed trailers, personnel can only use ladders or mobile operating platforms to access the vehicle, while for stake-lift trailers, they must climb a ladder at the junction of the cab and cargo box. This method of access is not only inefficient but also poses a significant safety hazard of falls from heights. Furthermore, during the lifting of large ballast assemblies of alumina, personnel have jumped off the crane to avoid the ballast assemblies, creating a major safety risk.

[0003] Existing mobile operating platforms still use vertical ladders, which are difficult to climb and affect the efficiency of ascending. At the same time, traditional mobile operating platforms do not have brakes, which poses a safety hazard. Furthermore, after climbing onto the vehicle using the car ladder, the personnel carrying the bags cannot avoid the hoisting route, which poses a significant safety hazard. Therefore, we propose a mobile support structure. Utility Model Content

Control handles 17 are fixedly installed on both sides of the threaded rod 10. Limit bolts 16 are threaded inside the control handles 17. Limit telescopic rods 8 are fixedly installed at the four corners of the working platform 7. Limit cylinders 9 are installed below the limit telescopic rods 8.

[0025] In this implementation plan: the support staircase 2 improves the efficiency of working at height, allowing workers to avoid the hoisting route when lifting large alumina ballast bags, thus reducing the risk of being struck by falling objects and greatly improving the safety of personnel; at the same time, by setting up an adjustable height work platform 7, the mobile support can be used with trailers with different height base plates.

[0026] Furthermore:

[0027] In an optional embodiment, the limiting cylinder 9 is welded to the bottom frame 1 of the bracket, and the limiting telescopic rod 8 extends and retracts inside the limiting cylinder 9.

[0028] In this implementation plan: when the work platform 7 moves up and down, the limiting telescopic rod 8 moves inside the limiting cylinder 9 to ensure the stability of the movement of the work platform 7.

[0029] Furthermore:

[0032] Furthermore:

[0033] In an optional embodiment, the limiting bolt 16 extends through the inside of the control handle 17, and the shape and size of the bottom of the limiting bolt 16 match the shape and size of the inside of the limiting groove 18, which is distributed in a ring shape inside the top plate 15.

[0034] In this implementation plan: the above technology ensures that the limiting bolt 16 can be limited by a limiting groove 18 no matter which position it is rotated to.

[0035] Furthermore:

[0036] In an optional embodiment, the stair platform 3 is further provided with:

[0037] The first protective fence 5 is fixedly installed above the stair platform 3. A toe board 4 is fixedly installed above the stair platform 3. The stair platform 3 is fixedly connected to the first protective fence 5.

[0038] In this implementation plan: the first protective fence 5 and the toe board 4 are used to block objects on the stair platform 3 to prevent objects on the stair platform 3 from falling and injuring people below.

[0039] Furthermore:

[0040] In an optional embodiment, the support staircase 2 further includes:

[0041] Stair railing 14 is fixedly installed on both sides above the support staircase 2.

[0042] In this implementation plan: the stair railing 14 can ensure the safety of staff when going up the stairs.

[0043] Furthermore:

[0044] In an optional embodiment, the work platform 7 further includes:

[0045] The second protective fence 6 is fixedly installed above the work platform 7.

[0046] In this implementation plan: the second protective fence 6 and the toe board 4 are used to block objects on the work platform 7 to prevent objects on the work platform 7 from falling and injuring people below.

[0047] Working principle: When using this mobile support, first push the mobile support to the side of the trailer using the four locking casters 13 under the support base frame 1. Then lock the locking casters 13. The locking casters 13 (model: wxl202) are existing technology with a locking function. Then, turn the limit bolt 16 to make the limit bolt 16 retract from the limit groove 18. By operating the handle 17, drive the threaded rod 10 to rotate clockwise or counterclockwise. Through the thread, the threaded rod 10 moves up or down inside the threaded cylinder 12. In turn, the top plate 15 pushes the working platform 7 up or down, adjusting the height of the working platform 7 to be aligned with the trailer. The base plate is at the same height. During this process, the limiting telescopic rod 8 moves inside the limiting cylinder 9 to ensure the stability of the working platform 7. Then, the limiting bolt 16 is turned in the opposite direction to insert it into the limiting groove 18, and the control handle 17 is fixed. Next, the workers walk to the working platform 7 through the support stairs 2 and the stair platform 3 to carry out the work. The toe board 4, the first protective fence 5, the second protective fence 6 and the support plate 11 can prevent objects from falling and injuring people. The stair railing 14 can ensure the safety of workers when going up the stairs. The adjustable height range of the working platform 7 is 1.3 meters to 1.6 meters. This is the working principle of the mobile support.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
