[0026] like Figure 1 As shown, the present invention includes two trolleys on the left and right: the left trolley includes a bottom plate 1, a baffle 12, and a reinforcing rib 5. The baffle 12 is perpendicular to the bottom plate 1, and the reinforcing rib 5 is perpendicular to the bottom plate 1 and the baffle 12; a hydraulic telescopic cylinder 10 is provided at the center of the baffle 12, and a bracket 3 is provided at the bottom of the hydraulic telescopic cylinder 10 for support; a universal steel wheel 2 and a steel roller 4 are provided at the bottom of the bottom plate 1; and a hydraulic oil pump station 13 is located on the left side of the baffle 12. The right trolley includes a V-shaped baffle 6, a bottom plate 1, and a reinforcing rib 5. The V-shaped baffle 6 is perpendicular to the bottom plate 1, and the reinforcing rib 5 is perpendicular to the bottom plate 1 and the V-shaped baffle 6; an annular limiter 8 is located on the upper part of the hydraulic adjustment cylinder 9; a track wheel slot 7 is located on the right V-shaped baffle 6 of the trolley; and a universal steel wheel 2 and a steel roller 4 are provided at the bottom of the bottom plate 1.

[0027] The two trolleys are connected and fixed together by four long bolts 11. To facilitate the disassembly and assembly of the long bolts 11, the diameter of the bolt hole is slightly larger than the outer diameter of the bolt.

[0028] The annular limit member 8 is fixed to the upper part of the hydraulic adjustment cylinder 9; the annular limit member 8 is divided into an upper half ring 17 and a lower half ring 18, which are connected by connecting bolts 16. The inner diameter of the annular limit member 8 is slightly larger than the outer diameter of the track wheel axle 24; for the convenience of installation and disassembly, the lower end of the hydraulic adjustment cylinder 9 is fixed to the channel steel base 20 by a base bolt 19.

[0029] The vertical center lines of the hydraulic telescopic cylinder 10 , the hydraulic adjustment cylinder 9 , the V-shaped baffle 6 and the track wheel clamping groove 7 are located in the same plane to ensure that they are coaxial with the track wheel axle 24 .

[0030] The track wheel slot 7 is provided with a clamping bolt 14 and an adjusting bolt 15. When installing the track wheel 23, the track wheel 23 is adjusted by the clamping bolt 14 and the adjusting bolt 15, and its inner contour is slightly larger than the outer contour of the track wheel 23 to be removed, so as to facilitate the insertion of the track wheel 23. The device does not work when the track wheel 23 or the bearing is removed.

[0031] The base of the hydraulic telescopic cylinder 10 is fixed to the baffle 12 by bolts to limit its axial displacement; the lower part is fixed by the hydraulic telescopic cylinder bracket 3 to limit its vertical displacement; the hydraulic telescopic cylinder bracket 3 is composed of a semicircular ring block 21 and a support plate 22.

[0032] Two universal steel wheels 2 and two steel rollers 4 are respectively arranged at the lower part of the two trolley bottom plates 1 for moving or steering the trolleys. To facilitate the installation and disassembly of the universal steel wheels 2 and the steel rollers 4, they are fixed to the legs under the bottom plates 1 with long bolts 11.

[0033] The hydraulic oil pump station 13 provides hydraulic oil for the hydraulic adjusting cylinder 9 and the hydraulic telescopic cylinder 10, and is located on the left side of the baffle 12 of the left trolley. To facilitate the disassembly and assembly of the pipelines, the oil supply pipeline joints between the hydraulic oil pump station 13 and the hydraulic telescopic cylinder 10 and the hydraulic adjusting cylinder 9 use high-pressure quick connectors.

[0034] The steps for disassembling the rail wheels of a battery locomotive are as follows:

[0035] First, prepare the above-mentioned disassembly and assembly device in a relatively flat site, assemble the various components according to the connection method of the device, and connect the quick connectors of the hydraulic adjustment cylinder 9, the hydraulic telescopic cylinder 10 and the hydraulic oil pump station 13. Then put the shaft (railway wheel shaft 24) of the track wheel 23 to be disassembled in the annular limiter 8, the track wheel 23 is located on the outside of the two V-shaped baffles 6, and the shaft is made coaxial with the hydraulic telescopic cylinder 10 through the hydraulic adjustment cylinder 9, and the upper half ring 17 of the annular limiter 8 is fixed to prevent the shaft from tipping over during the disassembly process, and then the hydraulic telescopic cylinder 10 is extended by controlling the hydraulic oil pump station 13, and the outer side of the wheel rim of the track wheel 23 gradually clings to the outer side of the V-shaped baffle 6 of the right trolley. During the continuous extension of the hydraulic telescopic cylinder 10, the track wheel shaft 24 is gradually pushed out by the piston rod of the hydraulic telescopic cylinder 10. Since the shaft is a stepped shaft, when the gap between the track wheel 23 and the shaft becomes loose, the hydraulic telescopic cylinder 10 retracts, and the loose track wheel 23 is removed manually and mechanically. Then unplug the quick connector between the hydraulic adjusting cylinder 9 and the hydraulic oil pump station 13, and remove the nut of the long bolt 11. After the right trolley rotates 180° on the spot, install the nut of the long bolt 11, fix the two trolleys, connect the quick connector between the hydraulic adjusting cylinder 9 and the hydraulic oil pump station 13, and make the hydraulic adjusting cylinder 9 coaxial with the hydraulic telescopic cylinder 10. Repeat the above disassembly steps. After the second track wheel 23 is removed, open the annular limiter 8, remove the track wheel axle 24, and the disassembly process is completed.

[0036] The installation steps of the battery locomotive rail wheel are as follows:

[0037] First, prepare the above-mentioned disassembly and assembly device in a relatively flat site, assemble the various components according to the connection method of the device, and connect the quick connectors of the hydraulic adjustment cylinder 9 and the hydraulic oil pump station 13. Then put the track wheel 23 of the locomotive group to be installed into the track wheel slot 7, put the shaft in the annular limiter 8, make the shaft and the hydraulic telescopic cylinder 10 coaxial through the hydraulic adjusting cylinder 9, fix the upper half ring 17 of the annular limiter 8, and then adjust the adjusting bolt 15 at the bottom of the track wheel slot 7 to make the track wheel 23 and the track wheel axle 24 coaxial, then tighten the clamping bolt 14, start the extension switch of the hydraulic telescopic cylinder 10, and in the process of continuous extension of the hydraulic telescopic cylinder 10, the track wheel axle 24 is gradually pushed into the inner contour of the track wheel 23, when the track wheel axle 24 reaches the installation position, retract the hydraulic telescopic cylinder 10, and then loosen the clamping bolt 14, open the upper half ring 17 of the annular limiter 8, manually cooperate with the machine to rotate the installed track wheel 23 and the track wheel axle 24 180°, and the track wheel 23 is located at the right The track wheel axle 24 is placed in the annular limiter 8 at a certain distance to the outside of the left V-shaped baffle 6 of the side trolley. The track wheel axle 24 is made coaxial with the hydraulic telescopic cylinder 10 through the hydraulic adjusting cylinder 9, and then the upper half ring 17 of the annular limiter 8 is fixed, and then the track wheel 23 of another locomotive group to be installed is placed in the track wheel slot 7, and the adjusting bolt 15 at the bottom of the track wheel slot 7 is adjusted to make the track wheel 23 coaxial with the track wheel axle 24, and then the clamping bolt 14 is tightened, and the extension switch of the hydraulic telescopic cylinder 10 is started. During the continuous extension of the hydraulic telescopic cylinder 10, the track wheel axle 24 is gradually pushed into the inner contour of the track wheel 23.
