[0037] Reference Figure 1 - Fig.15A side skirt plate 1 is fixed on both sides of the rail working vehicle and on the side away from the front of the vehicle. A gate 4 is installed between the two symmetrically arranged first guardrails 2 and the second guardrails 3, so that the operating personnel can enter the operating platform of the rail working vehicle through the gate 4. At the same time, the L-shaped structure of the first guardrail 2 allows the side close to the rear of the rail working vehicle to be protected, and a avoidance opening 21 is reserved on the rear side of the vehicle. The trailer hook at the rear of the rail working vehicle is placed at the avoidance opening 21 to avoid interference with the trailer hook when the two sets of first guardrails 2 are raised or lowered. The lower edges of the first guardrail 2 and the second guardrail 3 are fixedly connected by a lower crossbeam 5. The cylinder body of the first hydraulic cylinder 7 is fixed on the outer surface of the side skirt plate 1, and the upper end of the cylinder body is coplanar with the operating platform, and the lower end of the cylinder body is placed above the rail to avoid scratching the cylinder body during movement. The piston rods of multiple sets of first hydraulic cylinders 7 The upper ends are respectively fixed to the upper edges of the first guardrail 2 and the second guardrail 3, and the first guardrail 2 and the second guardrail 3 are vertically slidably connected to the side skirt 1, and then the first guardrail 2 and the second guardrail 3 and the gate 4 are adjusted by telescopic adjustment of multiple groups of first hydraulic cylinders 7, so as to finally adjust the spatial layout of the operating platform of the rail operating vehicle, and the first guardrail 2 and the second guardrail 3 and the gate 4 after being lowered are placed on the outside of the rail operating vehicle, which also solves the problem of storing the guardrail, and when the first guardrail 2 and the second guardrail 3 and the gate 4 are raised to protect the operating platform of the rail operating vehicle, the support mechanism 6 can drive multiple support plates 64 to slide horizontally and support under the lower cross beam 5 to improve the support reliability of the guardrail, and there is no need to disassemble and assemble bolts as a whole, so as to quickly adjust the spatial layout of the operating platform.

[0038] The first guardrail 2 and the second guardrail 3 both include an upper crossbeam 31, a crossbar 32, a column 33 and a slider 34. The upper crossbeam 31, the crossbar 32 and the lower crossbeam 5 are arranged in parallel. A plurality of columns 33 are vertically fixed between the upper crossbeam 31, the crossbar 32 and the lower crossbeam 5. The plurality of columns 33 are vertically fixed with sliders 34. The outer surface of the side skirt plate 1 is fixedly mounted with a plurality of guide rails 13 adapted to slide with the sliders 34. The upper edge axis of the gate 4 is rotatably connected with a buckle plate 41.

[0039] Reference Fig.13 - Fig.15The upper crossbeam 31 of the first guardrail 2 is provided with two groups and is vertically arranged. A plurality of columns 33 are vertically fixed on the upper crossbeam 31, the crossbar 32 and the lower crossbeam 5. The lower ends of the columns 33 are fixed on the lower crossbeam 5, so that a guardrail structure is formed as a whole. A gate 4 is installed between the adjacent columns 33 of the first guardrail 2 and the second guardrail 3. The gate 4 is hinged to the columns 33 of the first guardrail 2 through hinges. The upper edge axis of the gate 4 on the side close to the second guardrail 3 is rotatably connected to the buckle plate 41. The buckle plate 41 is a channel steel with an opening facing downward. The opening of the buckle plate 41 is inserted into the upper crossbeam 31 of the second guardrail 3, so that the gate 4 can be installed on the second guardrail 3. The upper end of the piston rod of the first hydraulic cylinder 7 is fixed on the upper crossbeam 31. At least one group of first hydraulic cylinders 7 are fixed at the first guardrail 2 and the second guardrail 3, and a group of first hydraulic cylinders 7 are arranged on the right angle inner side of the first guardrail 2.

[0040] The supporting mechanism 6 also includes multiple groups of second hydraulic cylinders 61, connecting frames 62 and long strips 63. Multiple strip holes 12 are opened on the side skirt plate 1. The supporting plates 64 are slidably inserted into the strip holes 12. The cylinder body of the second hydraulic cylinder 61 is fixed to the inner wall of the side skirt plate 1. Multiple supporting plates 64 are fixed to the side of the long strip 63 close to the side skirt plate 1. The piston rod of the second hydraulic cylinder 61 is fixed to the long strip 63 through the connecting frame 62.

[0041] Reference Figure 5 - Figure 7 and Fig.11 and Fig.12 The second hydraulic cylinder 61 is perpendicular to the extension and retraction direction of the first hydraulic cylinder 7, the support plate 64 is slidably inserted into the strip hole 12, and when the first guardrail 2 and the second guardrail 3 are raised, and the lower edge of the lower cross beam 5 is placed above the strip hole 12, at this time, through the contraction of the second hydraulic cylinder 61, the piston rod drives the connecting frame 62 and the long strip plate 63 to approach the direction of the side skirt plate 1, and after fitting, the support plate 64 is supported under the lower cross beam 5.

[0042] A plurality of limiting protrusions 11 are fixed on the outer surface of the side skirt plate 1 , and a plurality of inner protrusions 51 are fixedly mounted on the inner surface of the lower cross beam 5 . The inner protrusions 51 are placed below the limiting protrusions 11 .

[0043] Reference Figure 5 , Fig. 9 , Fig.11 and Fig.14 When the first guardrail 2 and the second guardrail 3 rise, and the inner protrusion 51 and the limiting protrusion 11 abut against each other, the lower surface of the lower cross beam 5 is placed on the upper edge of the strip hole 12 to facilitate positioning of the lower cross beam 5. It is worth noting that in order to avoid interference between the inner protrusion 51 and the lower edge of the side skirt plate 1 when rising, the lower edge of the side skirt plate 1 is tilted five degrees inward.

[0044] A telescopic sleeve 71 is sleeved on the piston rod of the first hydraulic cylinder 7 .

[0045] Reference Figure 5 By sleeve-mounting a telescopic sleeve 71 on the piston rod of the first hydraulic cylinder 7, the upper end of the telescopic sleeve 71 is fixed on the upper cross beam 31, and the lower end is fixed on the first hydraulic cylinder 7, so that the piston rod is waterproof and dustproofed by the telescopic sleeve 71 during the telescopic process of the piston rod.

[0046] A connecting rod 35 is fixedly installed between two upright posts 33 on one side of the avoidance opening 21 , and the connecting rod 35 is fixed to the upper end of the upright post 33 .

[0047] Reference Figure 6 and Fig.13 The two sets of first guardrails 2 can be fixedly connected by the connecting rod 35, thereby improving the overall stability when the first guardrail 2 is raised or lowered. At the same time, the opening above the avoidance opening 21 can be blocked by the connecting rod 35 to prevent the operator from falling through the avoidance opening 21.

[0048] The support plate 64 is a slope structure, and the side of the support plate 64 close to the lower cross beam 5 is a slope structure.

[0049] Reference Figure 5 and Fig.12 After the inner protrusion 51 on the inner side of the lower cross beam 5 abuts against the limiting protrusion 11, when the support plate 64 moves toward the lower cross beam 5, the slope end of the support plate 64 can avoid interfering with the lower edge of the lower cross beam 5 and extending out, so that the support plate 64 is supported under the lower cross beam 5.

[0050] Working principle: Figure 1 For example, when the first guardrail 2 and the second guardrail 3 need to be lowered, the second hydraulic cylinder 61 is operated to make the piston rod extend from the cylinder body, and the piston rod pushes the connecting frame 62 and the long strip 63 to slide inward, and the slope end of the support plate 64 is placed in the strip hole 12. At this time, the support plate 64 does not affect the lower cross beam 5 and the first guardrail 2 and the second guardrail 3. Then the first hydraulic cylinder 7 is started, and the piston rod is retracted into the cylinder body, and the piston rod drives the lower cross beam 5 and the first guardrail 2 and the second guardrail 3 to descend, and the slider 34 slides downward along the guide rail 13, so that the gate 4 and the first guardrail 2 and the second guardrail 3 are stored outside the rail working vehicle, so that the spatial layout of the operating platform of the rail working vehicle can be adjusted;

[0051] During recovery, the piston rod of the first hydraulic cylinder 7 extends upward and supports the gate 4 and the first guardrail 2 and the second guardrail 3 to rise. At the same time, when the inner protrusion 51 abuts against the limit protrusion 11, the second hydraulic cylinder 61 is started again to shrink the piston rod into the cylinder body. At this time, the connecting frame 62 pushes the long strip 63 and the support plate 64, and the support plate 64 is supported on the lower surface of the lower cross beam 5, so that the support status adjustment of the gate 4 and the first guardrail 2 and the second guardrail 3 can be completed.
