Description

Technical Field

[0001] The utility model relates to the technical field of walkways for trailers, tanks and equipment platforms in the field of petroleum equipment, in particular to a novel folding walkway. Background Art

[0002] In the field of petroleum equipment, trailers, tanks, equipment platforms and other equipment often use walkways on the edge of the main structure for personnel passage and operation and maintenance. Currently, common walkways generally use the operation method of turning upside down or disassembling when transporting equipment, but there are the following shortcomings:

[0003] 1) For traditional flip-up walkways, the railings need to be removed before operation can continue. However, this is only applicable to operations at a certain height. When the walkway is in high position, the operation is very difficult and there may even be operational risks.

[0004] 2) For walkways with a disassembly design, the railings must be removed in advance and then disassembled and assembled using a crane or forklift. Furthermore, when the walkway is located high up, there are risks associated with working at height.

[0005] 3) Both the traditional flip structure and the disassembly and assembly design have the disadvantage that they cannot be operated by one person.

[0006] In order to solve the above-mentioned shortcomings of traditional walkways, a new type of foldable walkway design is proposed to make the use and operation of the walkway simpler and more convenient. Utility Model Content

[0011] As optimization, the opposite sides of the fixed plate and the rotating beam are provided with double lugs that cross each other, and a connecting stud is arranged between the two crossing double lugs, and the two ends of the connecting stud are provided with nuts located outside the double lugs.

[0012] As optimization, the width of the limiting groove is greater than the width of the upper surface of the rotating beam.

[0013] As optimization, the length of the rotating beam is greater than the width of the bottom plate.

[0014] As optimization, a plurality of hinges are arranged between the bottom plate and the fixed plate.

[0015] The beneficial effects of the novel folding walkway provided by the utility model are as follows: the walkway is supported by multiple rotating beams, the material specification of the walkway is reduced while the stability of the walkway is increased, the material consumption of the traditional walkway for meeting the self-supporting strength is optimized, and the weight of the walkway is reduced; the walkway adopts an upward folding structure, and a single person can fold the walkway at different positions on the equipment main body according to the weight optimization of the walkway; the walkway rail is designed to rotate with the walkway support beam, and a single person can fold the rail and multiple rotating beams to the walkway mounting surface of the equipment main body at one time through rotation operation.

The rotating lock pin of the walkway body 3 is opened, and the walkway body 3 is flipped downward 90° to fit with the rotating beam 2, so that the limit groove 7 is stuck to the upper frame of the rotating beam 2.

[0033] When the walkway is folded from the working state to the transport state, the walkway body 3 is flipped upward 90° and separated from the rotating beam 2. The folded walkway body 3 is locked by rotating the locking pin of the walkway body 3. The rotating beam 2 is rotated 90° around the rotation axis and is parallel to the installation surface of the walkway body 3. The folded rotating beam 2 is locked by the rotating beam locking pin 6.
