Problems solved by technology
This greatly restricts the self-moving speed. At the same time, it is difficult to realize the accurate parking position of the flatbed truck. The pushing rod of the propulsion cylinder must be positioned.
[0004] The brake valve is a failure brake. Since the inlet and return fluid of the original hydraulic system are both KJ10 pipe diameters, and the system pipeline is long and the liquid flow is small, this makes the flu

The invention discloses a track hydraulic self-advancing flat car and a movement control method thereof. The track hydraulic self-advancing flat car comprises a plurality of car bodies are connected in sequence, a first operating valve, a second operating valve, a third operating valve, a hydraulic bidirectional lock, a propelling oil cylinder, a front car body brake and rear car body brake. The propelling oil cylinder is connected between the first car body and the second car body of the multiple car bodies. The front car body brake is arranged on the first car body. The rear car body brake is arranged on the second car body. The first operating valve is connected with the front car body brake. The second operating valve is connected with the rear car body brake. Two ports of the hydraulic bidirectional lock communicate with a third valve, and the other two ports of the hydraulic bidirectional lock communicate with the propelling oil cylinder. The hydraulic bidirectional lock is used for controlling the propelling oil cylinder, the operating valves can return to the zero position at any time after an operator shifts the operating valves, the operating valves do not need to be controlled manually, and thus the self-advancing step pitch of the flat car can be set as required; and meanwhile, sliding of the flat car due to retraction of the oil cylinder is avoided.
Description
technical field [0001] The invention relates to a transportation device for a fully mechanized mining face in a coal mine, in particular to a track hydraulic self-moving flatbed vehicle and a control method for its movement. Background technique [0002] The track hydraulic self-moving flatbed car is used for transporting the roadway in the fully mechanized mining face of the coal mine. The equipment uses the existing emulsification pump station on the working face as power, operates the hydraulic valve handle, and realizes the convenient and quick movement of flatbed trucks, switches, cables, etc. as the working face advances, thereby reducing the frequency of movement of equipment, cables, etc. The effect of reducing the number of staff and greatly reducing the labor intensity of workers. The use of hydraulic self-moving flatbed truck can completely change the traditional winch pulling method, which greatly improves the safety production factor and efficiency. However, t...
