[0035] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0036] Embodiment 1

[0037] In a typical implementation of the present invention, reference is made to Figure 1-Figure 8 As shown, a foldable walkway structure for an excavator includes a platform side beam, a mounting seat, and a walkway structure mounted on the platform side beam 2 through the mounting seat and rotatably matched with the platform side beam. The walkway structure is composed of multiple walkways 1 arranged and spliced ​​in sequence. When transporting, the walkway can be lowered and folded, and when the transportation is completed, the walkway structure can be unfolded.

[0038] like Figure 1 and Figure 2 As shown, each walkway is a rectangular plate structure, with a mounting plate 11 on the front side and an outer baffle 14 on the rear side. The mounting plate 11 and the outer baffle 14 are parallel, and the left and right ends of the two are surrounded by a left plate 12 and a right plate 13 to form a frame structure.

[0039] The top of the frame structure is connected by an anti-skid plate, on which anti-skid holes are evenly distributed for carrying people to walk.

[0040] like Figure 2 As shown, the bottom plate of the anti-skid plate is provided with a plurality of parallel vertical plates 16, which are vertically welded to the anti-skid plate, and the vertical plates 16 are perpendicular to the length direction of the anti-skid plate. The two ends of the vertical plates 16 are welded to the mounting plate 11 and the outer baffle plate 14 to improve the structural strength of the platform. A reinforcing plate 17 is provided between adjacent vertical plates to further improve the integrity of the platform. The reinforcing plate 17 can also be welded between the vertical plates 16 and the side plates, depending on the needs. The side plates are variable cross-section structures, which reduce the structural weight while ensuring strength.

[0041] like Figure 2 As shown, at least two mounting blocks 15 are welded on the outside of each mounting plate 11. The mounting blocks 15 are block-shaped structures, and second bolt holes are provided on the mounting blocks 15. The second bolt holes penetrate the mounting blocks 15 and the mounting plates 11. The side beams are provided with fixing holes 5 at positions corresponding to the mounting blocks 15. The second bolt holes are used to dock with the fixing holes 5. After docking, the fixing bolts are used to fix the walkway to the side beams after the walkway is unfolded.

[0042] like Figure 3 As shown, the platform side beam 2 is also provided with a plurality of mounting holes 6 for mounting a mounting seat on the side beam, wherein the mounting seat comprises two L-shaped mounting seats 3 and a plurality of T-shaped mounting seats 4 located between the L-shaped mounting seats 3 .

[0043] One end of the L-shaped mounting seat 3 is fixedly connected to the mounting hole by bolts, and the other end is set perpendicularly to the side beam. The top horizontal plate of the T-shaped mounting seat 4 is fixedly connected to the mounting hole by bolts, and the extension direction of the vertical plate is the same as the extension direction of the L-shaped mounting seat 3. The extension part serves as a matching part for matching with the side plate of the walkway. The plane where the matching parts of the two sets of mounting seats are located is set perpendicularly to the horizontal plane. The installation position relationship of the mounting seat is as follows: Figure 3shown.

[0044] like Figure 3 As shown, the two sides of the matching part of the T-shaped mounting seat 4 are used to match the adjacent side panels of the adjacent walkway, and one side of the L-shaped mounting seat 3 is used to match the front end of the walkway side panel at the end. Two first bolt holes are provided on the matching part of the mounting seat, and the first bolt holes are arranged along the direction of the mounting seat away from the side beam.

[0045] like Figure 1 As shown, the front ends of the left plate 12 and the right plate 13 are provided with an oblong hole 121 and a positioning hole 122 , the positioning hole 122 is located above the oblong hole 121 , and the rear ends of the left plate 12 and the right plate 13 are provided with a limiting hole 123 .

[0046] By setting the rear end limiting hole 123, the side panels of a plurality of arranged walkways can be fixed together by bolts, so that when the walkway structure is rotated, all the walkways can be linked.

[0047] When the walkway is linked and unfolded, the oblong hole 121 corresponds to the first bolt hole on the mounting seat close to the side beam, and the rotating pin is inserted. Then, the second bolt hole on the mounting block cooperates with the fixing hole, and the fixing bolt 9 is installed. At this time, the walkway structure is unfolded and fixed to the side beam. The walkway structure and the platform 7 are located in the same plane. Figure 7 shown.

[0048] When transporting, the walkway needs to be folded to reduce the volume of the vehicle. At this time, first remove the fixing bolts 9 at the mounting block 15, and the walkway structure is now unfixed from the side beam. Afterwards, under the action of gravity, the walkway can rotate downward with the pin as the rotation point, but due to the limitation of the mounting block 15, the walkway is stuck. Since the oblong hole 121 cooperates with the first bolt hole on the inner side, the oblong hole allows the walkway and the mounting seat to slide relative to each other. At this time, if the walkway is pulled outward, there will be no contact between the mounting block 15 and the side beam, and the walkway can be rotated downward to achieve folding.

[0049] In order to prevent the walkway from rotating arbitrarily during transportation, it is necessary to fix the position of the walkway after folding. After the walkway is rotated downward 90°, it is parallel to the side of the side beam. At this time, the positioning hole 122 is aligned with the first threaded hole on the outside of the mounting seat, and then the limiting bolt is used to cooperate with the positioning hole 122 and the first threaded hole. At this time, after the walkway structure is folded, under the action of the limiting bolt 10 and the rotating pin 8, the walkway cannot rotate arbitrarily to ensure safety. Figure 8 When the walkway needs to be unfolded again, just do the reverse operation.

[0050] like Figure 3As shown, the mounting holes are vertically arranged on the side beam, and there are three mounting holes from top to bottom. The first and second mounting holes are used to realize the fixed connection of the mounting seat. The distance between the third mounting hole and the first mounting hole can be adapted to the connection of the fixed walkway. Therefore, the combination of different mounting holes is used to adapt to the installation requirements of the mounting seat or the fixed walkway, realizing the replaceable setting of the fixed walkway and the folding walkway, which can meet the installation requirements of different walkway types and realize interchangeability.

[0051] The whole machine of this embodiment does not need to be disassembled for transportation. When transporting, the platform structure only needs to be folded to meet the width restriction requirements during transportation. The folding platform and the fixed platform are interchangeable, and different types of platforms can be configured according to different needs.

[0052] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
