Universal anti-running device for parked locomotives and vehicles

Abstract

The invention provides a universal anti-running device for parked locomotives and vehicles and belongs to the technical field of braking of the locomotives in marshalling yards. Two four-rod mechanisms are respectively arranged on two sides of an axis of a parallel hydraulic cylinder, and each four-rod mechanism is composed of a bottom beam, a connecting rod, a support arm and an intermediate connecting plate. A positioning shaft at the front end of each support arm is embedded into one fastening groove of a support arm fixing seat, a horizontal pin boss is arranged on the inner side of each intermediate connecting plate connected with one end of one horizontal connecting rod through a dowel, and the other end of each horizontal connecting rod is connected with horizontal pin bosses at two ends of the hydraulic cylinder. The outer sides of cross arms arranged along the bottom beams are provided with front connecting rod seats, one ends of the connecting rods are connected with the front connecting rod seats through dowels, and the other ends of the connecting rods are connected with pin bosses beside the support arms through pins. Positioning pins are arranged on the outer end faces of the support arms, the inners of the two support arms are provided with perpendicular surfaces, one of the perpendicular surfaces and the intermediate connecting plates are fixed through bolts, and springs are arranged between the other perpendicular surfaces and the intermediate connecting plates. The universal anti-running device is mainly used for dynamic and static anti-running braking on railways.

Description

[0001] Field [0002] The invention belongs to the technical field of locomotive and vehicle braking in railway marshalling yards. The utility model relates to a rolling stock brake device on a railway yard line. Background technique [0003] At present, most of the railway locomotives or vehicles (columns or groups) staying in places such as maintenance lines, loading and unloading lines, high slopes, and special lines still use the original anti-slip methods. These methods mainly include: 1. 2. Horizontal sleepers on the track; 3. Hand brake or iron (wooden) shoes, etc. These methods rely on people's skills, physical fitness, eyesight, and work responsibility, and are affected by the natural environment, which poses serious safety hazards. Many safety accidents have occurred, causing heavy losses to national property. The locomotives or vehicles staying on the arrival and departure line of the railway marshalling station not only adopt the original method to prevent slippi...

Problems solved by technology

These devices are mainly divided into four types according to their working principles: pneumatic type, hydraulic drive type, hydraulic relief type and screw drive type, among which the hydraulic relief type and hydraulic drive type are mainly used for the tail of the shunting line in the marshalling station. For anti-slip braking, hydraulic relief type and hydraulic drive type, the hydraulic system needs to maintain pressure for a long time to realize the change or maintenance of the working state of the parking equipment. Once the hydraulic system leaks, the equipment will lose its function and the reliability of the equipment is low. There are potential safety hazards. In addition, hydraulic relief type and hydraulic drive type parking anti-roller, the brake rail cannot be raised and lowered, and the lead machine cannot enter the shunting line from the tail end. When the locomotive needs to enter the operation from the tail end, it must be operated by The completion of the machine adjustment at the station will increase the cost of transportation operations and affect the efficiency of transportation operations; the wind-operated parking anti-roller is used not only for dynamic braking of tailing vehicles, but also for static anti-rolling of vehicles stopping at the departure line. The slipper needs to set up a large pump room, lay complex pipelines, and the cost is expensive. At present, only a few stations are used in the tailing or arrival and departure lines; It is also used for static anti-slipping of parking vehicles on the departure line. Due to the harsh working conditions on site, the dust is large, the lubrication of the screw nut is not easy to guarantee, and wear is inevitable. At the same time, a single motor drives multiple Due to the different force of each brake joint and the elastic deformation of the screw rod, the synchronization cannot be guaranteed, resulting in different wear degrees of the screw rod, which in turn affects the braking effect. To maintain a good equipment condition, it is necessary to It is necessary to increase the diameter of the screw rod and at the same time ensure the lubrication of the screw rod, which will greatly increase the cost of equipment manufacturing and maintenance, and increase the labor intensity of the workers. Moreover, the screw rod is in the middle of the track. Once a car stays on the track, it will affect the maintenance work. Therefore, the screw-driven parking anti-slip device is not easy to maintain, the life is short, and the cost of use and maintenance is high, which affects the popularization and use

In addition, dynamic braking and static anti-slip of vehicles exist in general railway stations. Therefore, for stations or users, the more types of equipment used, the difficulty of maintenance and management will increase, and the cost of use and maintenance will increase.
