At present, a handcart is usually used for railway line maintenance. Existing trolleys are generally simple in structure and include only the frame, rollers, guardrails and other components to enable sliding on rails to transport materials, equipment and perform maintenance operations. However, since trains often pass over the rails, it is often necessary to advance the trolley to the accessory track for reasonable and rapid avoidance during maintenance. The equipment and devices used in maintaining railway lines should be considered for convenience in use to improve work efficiency, and it is apparent that existing carts do not have this feature. In addition, since the conventional cart is not provided with a parking member, the cart may accidentally slip during maintenance, and thus a safety accident may occur. If the parking component is arranged, the parking component is often required to be controlled when the vehicle is parked and maintained or the vehicle is moved, thus delaying time, influencing working efficiency, sometimes the vehicle is parked and maintained, the vehicle is easy to forget to park, and the risk of sliding the vehicle can occur.

the parking assembly 4 comprises an L-shaped fixing bracket 401, a parking connecting rod 402, a parking top plate 403, a first pressing rod 404 and a return spring 405, wherein one end of the L-shaped fixing bracket is fixed at the rear end of the frame 1, and the other end of the L-shaped fixing bracket extends to the upper part of the roller 2; the parking connecting rod 402 is arranged to pass through the fixing support 401 and the return spring 405 in turn, and the upper end of the parking connecting rod 402 is connected with the parking top sheet 403, and the lower end is connected with the brake block 406; the parking top piece 403 is arranged to be attached to the surface of the fixing support 401, one end of the parking top piece 403 is connected with the upper end of the parking connecting rod 402, and the other end of the parking top piece is connected with the lower end of the first pressing rod 404;

the cart assembly 5 comprises a transverse pushing rod 501, a pushing rod limiting part 503 and a vertical pushing rod 502 which are arranged on two sides of the transverse pushing rod 501, and a second pressing rod 504, one end of which is connected with the bottom end of the vertical pushing rod 502, and the other end of which is in propping fit with the higher end of the first pressing rod 404; the push rod limiting part 503 is connected with the guardrail 3, and a push rod limiting groove 5031 is formed in the push rod limiting part 503 along the travelling direction of the handcart; the vertical push rod 502 penetrates through the push rod limiting groove 5031, the bottom end of the vertical push rod 502 is hinged with the guardrail 3, and the top end of the vertical push rod 502 is connected with the end of the transverse push rod 501;

the working principle of the utility model is as follows:

in the self-parking handcart for rail maintenance operation, parking and braking can be realized without applying force to the transverse pushing rod 501 when maintenance is required by parking. Naturally, when parking is required, the worker stops pushing the cart, i.e., stops applying force to the push rod 501, so that parking is realized without unnecessary operations or attention to parking operations. Specifically, when the lateral push rod 501 is not pushed, the second push rod 504 does not apply a force to the higher end of the first push rod 404; at this time, in the parking assembly 4, under the action of the pushing and extending of the return spring 405, the brake pad 406 is pressed down, so that the brake pad 406 contacts with the rolling surface of the roller 2, and thus the roller 2 cannot roll under the action of the friction force of the brake pad 406, thereby realizing automatic parking;

in the self-standing handcart process for rail maintenance operation, the transverse pushing rod 501 is forced when the handcart needs to be moved. Of course, when the vehicle needs to be moved, a worker needs to push the transverse push rod 501, namely, apply force to the transverse push rod 501, so that the vehicle movement is realized without the unnecessary operation of releasing the parking state; specifically, when pushing the transverse pushing rod 501, since the upper end of the vertical pushing rod 502 is connected with the end of the transverse pushing rod 501, the lower end of the vertical pushing rod 502 is hinged with the guardrail 3, and the lower end of the vertical pushing rod 502 is connected with the second pressing rod 504, so that the transverse pushing rod 501 drives the vertical pushing rod 502 to rotate around the hinged end thereof, and the second pressing rod 504 is further rotated to press the higher end of the first pressing rod 404; because one end of the parking plate 403 is connected with the upper end of the parking connecting rod 402, and the other end is connected with the lower end of the first pressing rod 404, the lower end of the first pressing rod 404 drives one end of the parking plate 403 connected with the parking connecting rod 402 to tilt after being pressed down, and the parking connecting rod 402 is slightly lifted, and further drives the brake block 406 to lift, so that the brake block 406 is separated from the rolling surface of the roller 2, the roller 2 can roll freely, and the movement of the trolley is realized;

In order to facilitate pushing and holding the transverse pushing rod 501, further, in a preferred embodiment, referring to fig. 2 and 3, a rubber grip 5011 is coated on the surface of the transverse pushing rod 501.

In order to prevent the first pressing rod 404 from swinging back and forth to separate from the second pressing rod, further, in a preferred embodiment, referring to fig. 1 to 4, the fixing bracket 401 is provided with a pressing rod limiting member 407; the pressure lever limiting member 407 is vertically provided with a pressure lever limiting groove 4071 along the length direction thereof, and the first pressure lever 404 is arranged to penetrate through the pressure lever limiting groove 4071.

In order to increase the friction between the brake pad 406 and the roller 2 to improve the parking effect, further, in a preferred embodiment, referring to fig. 3, the brake pad 406 has an arc-shaped structure matching with the rolling surface of the roller 2.

In order to increase the service life of the roller, further, in a preferred embodiment, the roller 2 is a steel wheel.
