A ladder frame connecting locking seat 19 is provided on the side of the transverse ladder frame 17, and a connecting locking plate 20 is inserted and installed on the ladder frame connecting locking seat 19, and a ladder 25 is provided on the side of the support plate 12.

[0030] The device is easy to assemble, disassemble, move and store, and can help maintenance personnel quickly climb to the top of the carriage. The assembly quantity and overall length of the device can be adjusted according to needs, and it can be moved along the outside of the carriage to facilitate the roof maintenance work of the entire carriage.

[0031] The transmission mechanism includes a screw rod 8 rotatably installed inside the lower support column 6, a first bevel gear 9 is sleeved on the outer side of the screw rod 8, a rocker arm 10 is rotatably installed on the outer side of the lower support column 6, one end of the rocker arm 10 is connected to the second bevel gear 11, and the second bevel gear 11 is meshed with the first bevel gear 9.

[0032] Rotating the rocker 10 drives the second bevel gear 11 to rotate, thereby driving the first bevel gear 9 to rotate together with the screw rod 8. The transmission between the screw rod 8 and the telescopic support column 7 drives the telescopic support column 7 to be raised and lowered. The telescopic support column 7 can be controlled to be lowered during assembly and separation, and to be raised when put into use.

[0033] The ladder frame connecting locking seat 19 and the connecting locking plate 20 are screwed and locked by a first bolt 21 .

[0034] The ladder frame connecting locking seat 19 and the connecting locking plate 20 are screwed and locked by the first bolt 21, so as to connect and fix the transverse ladder frames 17 of the two groups of maintenance tool vehicles.

[0035] One end of the cross beam plate 14 on the left combined trolley 1 and one end of the transverse ladder frame 17 are both provided with an insert plate 22, and one end of the cross beam plate 14 on the right combined trolley 2 and one end of the transverse ladder frame 17 are both provided with a slot 23, and the insert plate 22 and the slot 23 are inserted and connected and connected by a fixing pin 24.

[0036] The cross beam plate 14 of the left combined cart 1 and the cross beam plate 14 of the right combined cart 2 are connected by inserting plates 22 and slots 23, and the two sets of transverse ladder frames 17 are also connected by inserting plates 22 and slots 23, and fixed with fixing pins 24.

[0037] The first locking mechanism 13 and the second locking mechanism 18 both include a screw-connecting seat 26 , a locking clamping seat 27 is inserted and installed inside the screw-connecting seat 26 , and the screw-connecting seat 26 and the locking clamping seat 27 are threadedly connected via a second bolt 28 .

[0038] By tightening the second bolt 28 , the locking clamping seat 27 can be tightened, thereby clamping the cross beam plate 14 and the transverse ladder frame 17 .

[0039] The working principle and use process of the utility model are as follows: when the device is not in use, the left combined cart 1, the right combined cart 2 and the structures on the top thereof can be folded and stored. When the device is in use, the left combined cart 1 and the right combined cart 2 are pushed to the two sides of the track respectively, and the second bolt 28 is loosened to release the clamping state of the first locking mechanism 13 on the cross beam 14 and the clamping state of the second locking mechanism 18 on the transverse ladder frame 17. Then, the cross beam 14 is rotated to form a ninety-degree angle with the track, so that the cross beams 14 on the left combined cart 1 and the right combined cart 2 are aligned, and the transverse ladder frame 17 is rotated to be parallel to the track, and the cross beam 14 is slid to make the cross beams 14 on the left combined cart 1 and the right combined cart 2 close to each other. Thereby, the plug plate 22 and the slot 23 on the cross beam plate 14 are inserted and connected, and then the fixing pin 24 can be used to fix the plug plate 22 and the slot 23 to complete the docking combination of the cross beam plate 14, and then the transverse ladder frame 17 is slid to make the transverse ladder frames 17 on the left combined trolley 1 and the right combined trolley 2 approach each other, so that the plug plates 22 and the slots 23 on the two sets of transverse ladder frames 17 are inserted into each other, and then the fixing pin 24 is used to fix the plug plate 22 and the slot 23 to complete the docking combination of the transverse ladder frames 17. After completing this step, the second bolt 28 can be tightened to make the locking clamping seat 27 cooperate with the screw seat 26 to clamp the cross beam plate 14 and the transverse ladder frame 17, and then the rocker 10 is rotated to drive the second bevel gear 11 to rotate. Thereby, the first bevel gear 9 is driven to rotate together with the screw rod 8, and the transmission between the screw rod 8 and the telescopic support column 7 drives the telescopic support column 7 to rise to a height higher than the top of the car. According to the maintenance needs, multiple groups of maintenance tool carts can be connected and combined through the ladder frame connecting locking seat 19 and the connecting locking plate 20. When assembling, the transverse ladder frames 17 of the two adjacent groups of maintenance tool carts are aligned, and the connecting locking plate 20 is used to insert and connect the ladder frame connecting locking seat 19 at the connection of the transverse ladder frames 17, and the first bolt 21 is used to lock the connecting locking plate 20 and the ladder frame connecting locking seat 19, so as to complete the assembly between the two groups of maintenance tool carts. When performing maintenance, after the subway vehicle is driven to the inner side of the maintenance tool cart, the maintenance personnel can climb the ladder 2 5 climbs onto the cross beam plate 14, and can move on the top of the carriage through the transverse ladder frame 17 to repair the top of the carriage. During the maintenance process, the assistant under the car can directly help the maintenance personnel push the device to move along the direction of the carriage through the universal wheels 4 and the running wheels 5, which is convenient for the maintenance personnel to change the maintenance position. After use, the device can be quickly separated and folded. Each group of left-side combined carts 1 and right-side combined carts 2 can be moved separately through the universal wheels 4 and the running wheels 5, which is convenient for the transfer and storage of the device. In summary, the device is very convenient to assemble, disassemble, move and store, which can help the maintenance personnel quickly climb to the top of the carriage, and the assembly quantity and overall length of the device can be adjusted according to needs, and it can be moved along the outside of the carriage.It is convenient for the roof maintenance work of the entire train carriage.
