[0002] At present, the traditional railway handcart drives the wheels to rotate through a four-link and a gear transmission, thereby driving the handcart to move in one direction along the rail; there is no gear switch on the railway handcart, just push the handcart in the opposite direction, and then It is said that two people on the cart shake the rocker, which will make the handcart move in the opposite direction; when encountering a certain slope, the people on the cart must keep shaking the rocker to make the cart move continuously The front movement prevents the handcart from going backwards on the half slope; as a result, even if there is a brake mechanism, the person who shakes the rocker will be very tired. Increased risk, bringing safety hazards to people on handcarts

[0089] Specific embodiments: when the second ratchet 84 is engaged with the corresponding block 45, the third ratchet 51 is engaged with the corresponding block 45; at this time, two people on the handcart alternately shake the two cranks up and down 73, the rocker 73 drives the first gear 69 to reciprocate and rotate around the central axis of the rocker shaft 70 through the rocker 72, the first sleeve 71 and the rocker shaft 70; the first gear 69 drives the drive frame 33 through the first rack 38 Sliding reciprocally along the trapezoidal chute 29; since the second rack 35 and the third rack 36 are installed on the lower end face and the upper end face of the drive groove 34 respectively, so the drive frame 33 slides in one direction while the first toothed barrel 39 and the rotation direction of the second gear barrel 54 around the central axis of the first transmission shaft 58 are opposite; The block 45 alternately acts on the second ratchet 84 and the third ratchet 51; ...

The invention belongs to the railway engineering field, in particular to a handcart for railway tracks, which comprises a brake mechanism car mechanism, a transmission conversion mechanism and a rocker mechanism, wherein two axles are installed at the bottom of the car mechanism, and the two axles are distributed in front and behind the bottom of the car mechanism. The transmission conversion mechanism enables the railway handcart to travel in only one direction before gear shifting; when the railway handcart is traveling along the rail uphill section, even if the person on the railway handcart does not act on the swing handle, the railway handcart will not reverse under the action of its own gravity, thus avoiding the safety hidden danger caused by the reverse; as the railway handcart ofthe invention does not need the function of manpower and the assistance of the braking function when stopping on the half slope, the railway handcart of the invention does not need the braking function. After a period of rest in the middle of the slope, the handcart continues to move by shaking the handle, thereby saving as much energy as possible to ensure the continuation of the subsequent work.
