[0031] This embodiment provides a portable overhead contact line ladder vehicle, see reference. Figures 1-4 As shown, the system includes a chassis plate 1, with track wheels 11 connected to the lower part of the chassis plate 1. An insertion hole 12 is provided on the upper surface of the chassis plate 1. A ladder frame base 2 is connected to the upper part of the chassis plate 1. A first connecting plate 21 is provided at the lower part of the ladder frame base 2. A connecting column 211 is provided on the lower surface of the first connecting plate 21. A first support column 22 is connected to the upper surface of the first connecting plate 21. An insertion port is provided on the upper surface of the first support column 22. A ladder frame support member 3 is connected to the upper part of the ladder frame base 2. A second connecting plate 31 is provided on the upper part of the ladder frame support member 3. A second support column 32 is connected to the lower surface of the second connecting plate 31. An insertion block is connected to the lower surface of the second support column 32. An insertion port is provided on the upper surface of the second connecting plate 31. Ladder rods 4 are connected between the first support columns 22 and between the second support columns 32. A protective component 5 is connected to the upper part of the ladder frame support member 3.

[0032] In the above embodiment, a track wheel 11 is connected to the lower part of the chassis plate 1. The track wheel 11 is used to contact the track and roll with the locomotive track, so that the chassis plate 1 can move on the track. An insertion hole 12 is provided on the upper surface of the chassis plate 1. A first connecting plate 21 is provided at the lower part of the ladder base 2 and a connecting post 211 is provided on the lower surface of the first connecting plate 21. The insertion hole 12 at the upper end of the chassis plate 1 is used to insert and cooperate with the connecting post 211 on the lower surface of the first connecting plate 21, so that the ladder base 2 is inserted into the upper part of the chassis plate 1. Furthermore, the upper end face of the first connecting plate 21 is connected to the first support column 22, and the upper end face of the first support column 22 is provided with a socket. The upper part of the ladder support member 3 is provided with the second connecting plate 31, and the lower end face of the second connecting plate 31 is connected to the second support column 32. The lower end face of the second support column 32 is connected to the plug. The socket provided on the upper end face of the first support column 22 is used to engage with the plug on the lower end face of the second support column 32, so that the second support column 32 can be engaged with the first support column 22, thereby allowing the ladder support member 3 to be engaged on the upper part of the ladder base 2. In summary, a ladder frame is formed by interlocking the chassis plate 1 with the ladder frame base 2, and the ladder frame base 2 with the ladder frame support 3. This ladder frame is used to support workers above the track for maintenance of the overhead contact line. On the one hand, the corresponding splicing components of the ladder frame are smaller in volume than the overall ladder frame, making it easier to assemble and disassemble. In working environments with limited space, such as tunnels, the disassembled ladder frame components can be temporarily placed in the available space on both sides of the track to avoid collisions with passing trains. On the other hand, disassembling the ladder frame reduces the load on the chassis plate 1, making it easier for workers to lift the chassis plate 1 off the track so that trains can pass smoothly. This helps ensure the safety of workers and trains when using a ladder car to maintain the overhead contact line. In addition, ladder rods 4 are connected between adjacent first support columns 22 and adjacent second support columns 32. On the one hand, ladder rods 4 increase the support points for workers when climbing the ladder frame. On the other hand, ladder rods 4 connect adjacent support columns, which helps to improve the overall stability of the ladder frame. The upper part of the ladder frame support 3 is connected to a protective component 5 to protect workers and prevent them from falling from the top of the ladder frame, so as to ensure the safety of workers.

[0033] In one embodiment of this application, see [reference] Figure 1 As shown, a bracket assembly 6 is provided on the side of the chassis plate 1.

[0034] In the above embodiment, the support assembly 6 provided on the side of the chassis plate 1 supports the chassis plate 1, thereby increasing the support area of ​​the chassis plate 1 on the ladder frame, preventing the ladder frame from tipping over, and improving the stability of the chassis plate 1 in supporting the ladder frame.

[0035] In one embodiment of this application, see [reference] Figure 1 ,Figure 2 As shown, the side support assembly 6 includes a tripod 61, one end of which is rotatably connected to the base plate 1 via a pivot, and the other end of which is connected to a support rod 62, with a foot connected to the bottom end of the support rod 62.

[0036] In the above embodiment, one end of the tripod 61 is rotatably connected to the base plate 1 via a pivot, and the other end of the tripod 61 is connected to a support rod 62. The bottom end of the support rod 62 is connected to a foot. By deflecting the tripod 61, the support rod 62 can be moved, thereby changing the support point of the support rod 62 with respect to the ground. This facilitates the adjustment of the support point of the support rod 62 according to the actual situation, thereby improving the adaptability of the support assembly 6 to the support site. In addition, when the base plate 1 is moved away, the tripod 61 can be deflected and folded to the side of the base plate 1 to reduce the space occupied by the base plate 1, which facilitates the temporary storage of the base plate 1. Furthermore, the support rod 62 is detachably connected to the other end of the tripod 61 by bolts and nuts. Different lengths of support rod 62 can be replaced according to the actual support needs to improve the flexibility of the support rod 62. The bottom end of the support rod 62 is provided with a foot to increase the contact area between the bottom end of the support rod 62 and the ground, which is beneficial to improving the stability of the support rod 62.

[0037] In one embodiment of this application, see [reference] Figure 2 As shown, multiple sets of ladder support members 3 are provided between the protective component 5 and the ladder base 2.

[0038] In the above embodiments, multiple sets of ladder support members 3 are provided between the protective component 5 and the ladder base 2, which can be used to increase the actual height of the ladder. Similarly, reducing the number of sets of ladder support members 3 between the protective component 5 and the ladder base 2 can reduce the height of the ladder. Adjusting the height of the ladder by changing the number of ladder support members 3 is beneficial to improving the adaptability of the ladder truck's working height.

[0039] In one embodiment of this application, see [reference] Figure 2 As shown, the protective component 5 includes a plug rod 51, a plug block is provided at the bottom end of the plug rod 51, and a slot block 52 is connected to the side wall of the plug rod 51. The slot block 52 is used to fix the crossbar 53.

[0040] In the above embodiment, the insertion block at the bottom of the insertion rod 51 is used to engage with the insertion port at the upper end of the second connecting plate 31 of the ladder support 3, which facilitates the insertion and removal of the insertion rod 51 and the second connecting plate 31, and improves the flexibility of assembly. The side wall of the insertion rod 51 is connected to the slot block 52, which allows the crossbar 53 to be inserted into the slot of the slot block 52, so that the crossbar 53 is set around the top of the ladder frame, which plays a protective role for the workers and prevents the workers from falling when working at the top of the ladder frame, thus improving the working safety of the ladder truck.

[0041] In one embodiment of this application, see [reference] Figure 2 As shown, a searchlight 7 is installed on the side wall of the crossbar 53.

[0042] In the above embodiment, the searchlight 7 installed on the side wall of the crossbar 53 can be used to provide illumination during construction. On the other hand, the searchlight 7 can also serve as a marker and warning of the construction location, allowing the train to detect the construction location from a greater distance and brake in order to avoid the risk of collision.

[0043] In one embodiment of this application, see [reference] Figure 1 As shown, a handle 8 is installed on the side of the chassis plate 1.

[0044] In the above embodiment, the handle 8 installed on the side of the chassis plate 1 is used to provide a gripping point for the handling and removal of the chassis plate 1, which helps to improve the convenience of handling and transferring the chassis plate 1.

[0045] In actual use, the chassis plate 1 is placed on the track, with the track wheels 11 in contact with the track. The upper insertion hole 12 of the chassis plate 1 is inserted into the connecting post 211 on the lower end face of the first connecting plate 21, so that the ladder frame base 2 is inserted into the upper part of the chassis plate 1. The insertion port on the upper end face of the first support post 22 is inserted into the insertion block on the lower end face of the second support post 32, so that the ladder frame support 3 is inserted into the upper part of the ladder frame base 2. Figure 2 For example, the upper end face of the second connecting plate 31 is provided with an insertion port, which can be used to insert another ladder support 3 above the original ladder support 3 to adjust the support height of the ladder. The ladder cart can be pushed by manpower to move on the track.

[0046] During actual construction, blocks can be placed on both sides of the travel direction of the track wheel 11. The blocks are used to prevent the track wheel 11 from sliding on the track, so that the ladder truck stays stopped during construction and can improve the stability of the ladder truck during maintenance. After maintenance is completed, the blocks can be removed so that the track wheel 11 can move normally on the track again.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
