[0010] The utility model has the advantages of:

[0011] The utility model discloses a structure, the roller mechanism not only strengthens cross -country ability to satisfy the complex environment of railway scene, and through the position of change roller mechanism simultaneously, makes the tool box can travel steadily on the steel rail. Roller mechanism passes through spring wrench and the opening on roller mechanism and the roller frame can carry out quick disassembly and assembly, to reach the combination of roller frame and roller mechanism can realize the mode switching of tool box movement on the road surface and on the steel rail. The size of roller is increased to improve the cross -country of roller, and the maintenance personnel is convenient in rugged uneven road surface and pulls the tool box travel.

[0018] 3 is roller, 30 is roller seat, 31 is connecting plate, 32 is side plate, 33 is roller axle, 34 is folding edge, 35 is clamping groove, 36 is limiting block, 37 is spring piece, 38 is wrench; IMPLEMENTATION

[0019] The utility model discloses a tool box for rail transit electric service maintenance as shown in 1-4 discloses a kind of tool box for rail transit electric service maintenance, including box 1, fixed frame 2 and gyro wheel 3, fixed frame is fixed in the lower of box by bolt etc.;The fixed frame 2 is approximately "N" shape, including one vertical upper fixed plate 21, two horizontal middle fixed plate 22 and two vertical lower support plate 23;Three integrally cooperate.In upper fixed plate 21 upper end and two middle fixed plate 22 inner side, all vertically be provided with flanging 26;Among them, the flanging on upper fixed plate is vertically outward arranged, the flanging on middle fixed plate is downward arranged;Further including gyro wheel seat 30 matched with gyro wheel, gyro wheel seat includes connecting plate 31 and side plate 32, and side plate lower end is provided with gyro wheel shaft 33;Connecting plate one end is vertically provided with flange 34, and flange is provided with the opening matched with limiting block;When connecting plate is close to upper fixed plate or middle fixed plate, flange corresponds with flanging;Further including the clamping structure for realizing gyro wheel and fixed plate connection and the limiting structure for fixing clamping structure and preventing it from being separated;The clamping structure includes clamping block 24 respectively arranged on upper fixed plate and middle fixed plate, and clamping groove 35 arranged on connecting plate, after the clamping cooperation of two, the quick connection of gyro wheel and fixed plate can be realized;The limiting structure includes limiting slot 25 (flange is also provided with the opening corresponding therewith on flange) arranged on flange, and limiting block 36 is arranged on flange by spring piece 37.

[0020] Preferably, the clamping block is circular truncated cone (approximately mushroom shape), inner thin and outer thick;The clamping groove is a gourd shape, formed by the intersection of two horizontally arranged circular holes, and the large hole corresponds to the thick end of the clamping block, and the small hole corresponds to the thin end and is smaller than the outer diameter of the thick end.

[0021] Preferably, one end of the spring piece 37 is fixed to the lower side of the flange by a bolt or the like, and the other end of the spring piece 37 is fixed to the limiting block 36 on the upper side, and the lower side is fixed with a wrench 38.

[0022] Preferably, the gyro wheel is a groove wheel. The gyro wheel of the present scheme has two, located on the fixed frame, and the size is larger than the existing gyro wheel located at the corner, which is more convenient to use, and can improve the off-road performance of the gyro wheel to a certain extent.

[0023] The working process of the utility model structure is as follows:

[0024] The utility model structure can change the installation position of the gyro wheel, i.e. change the direction of the gyro wheel, so as to realize the purpose of converting driving on road surface and track.

[0025] When conversion is needed, the wrench is pulled to pull one end of the spring sheet down, the limiting block is separated from the limiting groove, then the large hole on the clamping groove is moved to the clamping block position by force, the roller seat is taken out forward, and is installed to the corresponding position. During installation, the large hole is aligned with the clamping block position, the roller seat is attached to the fixing frame, then the roller seat is moved transversely, the small hole is matched with the clamping block to be clamped and fixed, after being in place, the limiting block is automatically ejected under the action of the spring sheet to cooperate with the limiting groove, the roller seat is prevented from moving left and right, thereby effectively ensuring the clamping effect. Another group of rollers is treated in the same way, and quick installation conversion can be realized.

[0026] In the structure, the lower end of the box body is provided with a fixing frame, which can reinforce the tool box and improve the loading capacity of the tool box, and can also cooperate with the roller to realize the conversion walking of the road surface and the rail. The roller is quickly assembled and disassembled, quickly converted through the limiting mechanism and the clamping mechanism, the spring sheet wrench and the opening on the roller mechanism can be quickly disassembled and assembled, so that the mode of the tool box moving on the road surface and moving on the rail can be conveniently switched, and the adaptability is improved.
