The front wheel fixed part comprises two clamping plates, the two clamping plates are vertically fixed on the upper surface of the fixed plate, the distance between the two clamping plates is consistent with the width of the front wheel of the bicycle, through holes are correspondingly formed in the two clamping plates, locking bolts are matched in the through holes, and nuts are matched on the locking bolts.

Two bearing seats are fixed on the lower bottom surface of the fixing plate, the bearing seats are all axially provided with rotating shafts, rail face wheels and limiting wheels are axially arranged on the rotating shafts from the middle to two ends, the diameter of each limiting wheel is larger than that of each rail face wheel, and the limiting wheels are always positioned on two sides of a rail when the rail face wheels roll on the rail faces.

The fixed block is fixed on the frame on bicycle front wheel upper portion, sets up the screw hole on the fixed block, threaded hole fit brake bolt, and the brake block is fixed to brake bolt lower extreme, and the precession brake bolt makes the crowded tight front wheel of brake block, can restrict the front wheel and rotate.

The working principle and the process are as follows:

during operation, the front wheel is clamped between the two clamping plates, then the locking bolt penetrates through the through holes in the two clamping plates and is fixed by the nuts, the locking bolt penetrates between the spokes, the fixing plate and the front wheel are fixed in relative positions, then the rail surface wheel is placed on the rail surface, the limiting wheel is located on two sides of the rail, the limiting wheel prevents the rail wheel from deviating, and the aligning effect is achieved (if the rail wheel is obtained through tests, if only one group of rail surface wheel and one group of limiting wheel are arranged, the limiting wheel is easily extruded with the side edge of the rail during operation, so that the operation is unsmooth). After the two groups of rail surface wheels are in contact with the rail surfaces, the brake bolts are screwed in, so that the brake pads are tightly extruded on the front wheels, the rotation of the front wheels is limited, and the two groups of rail surface wheels can be ensured to be in contact with the rail surfaces all the time. The rail face wheel and the limiting wheel are two groups, and compared with one group, the stability is stronger, and the rail face wheel and the limiting wheel are not easy to be extruded to the side edge of the rail, so that the operation is smoother. When the vehicle runs on a rail, the bolt is pulled down, the extension rod and the main vertical rod are pulled down, the brake bolt is unscrewed, and then the vehicle can run on a normal road surface.

Compared with the prior art, the utility model beneficial effect who has is:

dual-purpose maintenance bicycle front wheel guiding mechanism of railway and highway, flexible, can remain stable on the rail, safe and reliable to the cost of manufacture is extremely low, but the greatly reduced spending after promoting on a large scale, and improve maintenance efficiency greatly.

Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in fig. 1-5, dual-purpose maintenance bicycle front wheel guiding mechanism of railway highway, including front wheel clamping device, front wheel clamping device includes fixed plate 10, fixed plate 10 upper surface sets up the front wheel fixed part, install two sets of rail surface wheels 2 on the front wheel fixed plate 10 lower surface side by side, spacing wheel 12 is installed respectively at two sets of rail surface wheels 2 both ends, the distance between the two outer terminal surfaces of every group rail surface wheel 2 is less than the width on rail 3 upper portion, the distance between the terminal surface is greater than the width on rail 3 upper portion in the spacing wheel 12 at every group rail surface wheel 2 both ends, the horizontal position that spacing wheel 12 landed the place is less than the horizontal position that rail surface wheel 2 landed the place.

The front wheel fixed part includes two splint 8, and two splint 8 are vertical to be fixed on fixed plate 10 upper surface, and the interval of two splint 8 is unanimous with 1 front wheel width of bicycle, corresponds on two splint 8 and sets up the through-hole, and through-hole fit in locking bolt 9 cooperates the nut on the locking bolt 9.

Two bearing seats 11 are fixed on the lower bottom surface of the fixing plate 10, the bearing seats 11 are respectively axially provided with a rotating shaft 4, the rotating shaft 4 is axially provided with a rail surface wheel 2 and a limiting wheel 12 from the middle to two ends, and the diameter of the limiting wheel 12 is larger than that of the rail surface wheel 2, so that the limiting wheels 12 are always positioned at two sides of the rail 3 when the rail surface wheel 2 rolls on the rail surface.

Fixed block 6 is fixed on the frame on 1 front wheel upper portion of bicycle, sets up the screw hole on the fixed block 6, and threaded hole fit brake bolt 5, brake block 7 is fixed to 5 lower extremes of brake bolt, and precession brake bolt 5 makes the crowded tight front wheel of brake block 7, can restrict the front wheel and rotate.
