Problems solved by technology

Its biggest common shortcomings: First, the braking force is small and the anti-slip ability is poor
It is mainly used for anti-slip work on cargo lines and marshalling yards. Its disadvantages are: First, it has large limitations.
At present, my country's technical level in vehicle anti-slip is not advanced enough, and the countermeasures adopted in the anti-slip work are mainly to formulate measures and methods at the management level, without in-depth excavation at the technical level
In addition, the anti-slip action of the existing anti-slip devices for railway vehicles is independently operated and cannot be used in conjunction with the braking mechanism of the vehicle, especially the anti-slip device that has not been arranged on the brake cylinder of the railway vehicle. It will inevitably lead to a more complicated structure of the anti-slip device, and it is not convenient to install and use
[0011] However, advanced technical equipment is often more reliable than human beings, because human beings are unconscious, often affected by emotional regret, spirit, memory and other conditions, and have uncertainty, so it is also one of the unsafe factors, not the real essence Safety cannot fundamentally prevent the occurrence of vehicle slipping accidents. The above repeated vehicle slipping accidents are the most powerful proof of this point of view.

Embodiment 1

[0044] Mainly describe the implementation method and principle of manual operation pneumatic locking and automatic unlocking control.

[0045] like figure 1 As shown, first, installation is required. Install multiple mounting brackets at the bottom of the vehicle, support the exhaust valve control rod through the valve rod hoisting mechanism, and then support the travel lock through the travel body frame, and the lock iron support seat is used to support the locking teeth The lock iron, meanwhile, utilizes mechanical control to control the up and down movement of the bayonet lock iron. After the installation is complete, perform the braking action.

[0046] Pre-locking process: when the driver uses the usual brake to stop the train and takes anti-slip measures for the removed vehicles, the operator manually turns the two-way operating lever 22, and the two-way operating lever 22 is rotating in a small range. Simultaneously, drive drawbar 17 to pull to the left, the movement ...

Embodiment 2

[0051] like Figure 5 Shown, mainly be that the implementation mode of automatic control is different, and the air action mechanism of automatic control: is made up of air spring 26, return spring, spring support and three-way comprehensive action valve 25 that are installed in the latch lock iron bottom. , the telescopic end of the air spring 26 is connected to the bottom surface of the lock body plate 10 for controlling the lock body plate 10 to move up and down. There is a three-way comprehensive action valve 25 in the middle of the ventilation pipeline connected to the air spring 26, and the three-way comprehensive action valve 25 is composed of four valves, namely the relief valve K1, the pressure control valve K2, the reverse flow valve K3, and the differential pressure reverse flow valve K4 , wherein, the intake end of the mitigation release valve K1 is connected to the main brake line L1, the outlet end of the mitigation release valve K1 is connected to the first intak...

Abstract

The invention discloses a railway vehicle air braking anti-slip lock. The railway vehicle air braking anti-slip lock comprises a brake cylinder exhaust control mechanism, a brake actuation mechanism and a brake actuation control mechanism, wherein the brake cylinder exhaust control mechanism comprises an exhaust valve control drawbar and a valve drawbar hoisting mechanism, the valve drawbar hoisting mechanism mounts the exhaust valve control drawbar at the bottom of a carriage, and the exhaust valve control drawbar is used for controlling opening and closing the exhaust valve of a brake cylinder; the brake actuation mechanism comprises a running lock cylinder, a latch pin lock, a running unit and a pin lock support, the action control end of the running lock cylinder is connected with theextending end of the brake cylinder, the running lock cylinder is arranged above the latch pin lock through the running unit and runs along with extension and retraction of the brake cylinder, the running unit is mounted at the bottom of the carriage, the pin lock support is used for supporting the latch pin lock, and the running lock cylinder and the latch pin lock are locked in a clamped mode; the brake actuation control mechanism achieves mechanical control or pneumatic control over vertical movement of the latch pin lock.

Description

technical field [0001] The invention relates to the technical field of anti-skid locks for safe parking of railway air brake vehicles, in particular to an anti-skid lock for railway air brake vehicles. Background technique [0002] In recent years, slipping accidents of railway vehicles have occurred continuously. Vehicles during shunting operations, trains running in intervals, trains suddenly stopped in intervals and separated trains, trains parked at stations, trains temporarily parked, and vehicles parked on special lines, as well as loading and unloading. slip and escape accidents have seriously affected the safety of railway transportation. Once locomotives and vehicles run away, if they cannot be dealt with in time or take improper emergency measures, it will cause great economic losses and political influence. Anti-slip work has become the key point of railway transportation production safety, and it is also a systematic and long-term task of transportation, locomot...
