Technical Field

The utility model belongs to the technical field of the braking of cogged rail railway, especially, relate to a gear locking arresting gear that is used for swift current car is prevented to Strub cogged rail vehicle.

Background

The conventional urban rail train transmits power and braking force through steel wheels and steel rails. Usually, the limit gradient capable of climbing by the adhesion of steel wheels and steel rails is 40-60%, and an excessive gradient causes insufficient adhesion force due to the sliding of the contact surface of the steel wheels and steel rails, thereby causing a safety problem.

The rack-and-pinion railway is mainly driven by a rack and a pinion, specifically, on the basis of the traditional steel wheel rail railway, a gear is arranged on a train running mechanism, a rack is arranged on a track, and traction force and braking force are provided by the meshing action of the gear and the rack, so that the train is driven to run on the track. The toothed rail railway is gradually one of main transportation means for tourism in mountain scenic areas or transportation in mining areas in recent years due to the advantages of strong terrain adaptability, strong climbing capability, low construction cost, capability of being connected with a common railway and the like. The rack rail railway vehicle can climb a road section with a larger gradient by means of strong driving force provided by the gear between the rack rail laid between the steel rails and the steel wheel, and the maximum driving force can reach 480 per thousand.

The safety of the passengers of the operation vehicle as a travel route must be put in the first place and the safety performance of the rack rail vehicle must be sufficiently high. The rack rail vehicle is driven by the meshing between the gear disc and the rack rail, and the braking force acts on the rack rail through the gear disc. For example, chinese patent application No. CN 210793194U discloses a "toothed rail vehicle driving and braking device", which includes an axle, a toothed rail wheel mounted on the axle through a toothed rail wheel seat, a driving device for driving the toothed rail wheel to rotate, and a braking device for limiting the rotation of the toothed rail wheel. The invention discloses a belt type brake device and a brake device with the same, which comprises a brake drum, a brake belt, a spring, a release brake cylinder and a transmission mechanism. Both devices are braked by a driver manually operating a brake device, and main braking force is from a brake drum. However, when the rack-and-pinion vehicle works in a large slope environment for a long time, the pressure borne by the conventional braking device is huge, and the structure of the braking device is complex, so that mechanical failure is often easy to occur. If the brake drum is seriously worn, the electric control device fails, or hydraulic pressure provided by hydraulic device failure is insufficient, the toothed rail vehicle can lose the braking force, and especially the examination on the brake device is doubled when the toothed rail vehicle stays on a slope. Once the rack-and-pinion train slips down the slope, the personal safety of passengers is greatly threatened, and the consequences are not imaginable.

Because the related standards of the toothed rail railway are not clear at present, the problem of the braking safety protection measures of the toothed rail vehicle is still serious. Therefore, the gear locking braking device is designed by combining all the conventional braking modes. The common rack-and-pinion vehicle brakes by transmitting braking force to the rack through the gear disc, and the braking mode influences the contact between the gears and the transmission of the force after long-term operation and has great influence on the operating state of the gears. According to the prior patent 'toothed rail vehicle driving brake device', main braking force is from a brake drum, the braking effect is influenced after long-term operation like a traditional toothed rail braking mode, and the braking modes are difficult to maintain and replace.
