Abstract

The utility model relates to a tension spring type steel rope anti-sliding brake of a railway vehicle, which comprises a steel rope anti-sliding device assembly (16). The outer end of the steel rope (4) of the steel rope anti-sliding device assembly (16) is connected with a tension spring (7). Since the outer end of the steel rope is connected with the tension spring, the sudden increase of the tensile force of the steel rope can be damped through the elastic force of the tension spring when the wheels move in the direction opposite to the hand brake, thereby preventing the steel rope from breakage. Moreover, the utility model has the advantages of reasonable overall structural design, durability, safety, reliability and maintenance-free performance, and can be widely used in the anti-sliding braking of non-cab standing vehicles, loading and unloading vehicles and vehicles being repaired in the garage.

Description

The anti-drg that slips of rolling stock Extension Spring-type steel rope

Technical field

The utility model relates to the anti-drg that slips of a kind of rolling stock Extension Spring-type steel rope.

Background technology

Existing rolling stock steel rope is anti-to slip the anti-slide braking of drg when being used for rolling stock and remaining static, therefore the regulation anti-drg that slips in station must use when rolling stock remains static, but actual conditions are that wheel will produce displacement in the rolling stock stopping brake alleviation process, if to the displacement of rim brake direction, the then anti-drg pull of steel wire of slipping reduces, if to the displacement of rim brake opposite sense, the then anti-drg pull of steel wire of slipping can suddenly increase, and easily makes wire cable rupture.Especially power is bigger during the locomotive coupling vehicle, the disconnected rope of easier generation.In addition, the anti-drg that slips of existing rolling stock steel rope causes steel rope maintenance difficult when disconnected rope, folder rope, steel rope fatigue owing to the defective on the structure design, and particularly more change steel rope is more difficult, and the anti-drg that slips can only be scrapped when serious.

Summary of the invention

The technical matters that the utility model solves: design the anti-drg that slips of a kind of rolling stock Extension Spring-type steel rope, its steel rope external end head connects extension spring, phenomenon by tension spring buffering wheel lineoutofservice signal pull when the displacement of rim brake opposite sense suddenly increases prevents wire cable rupture.Its ratchet and steel rope twine the position and thoroughly isolate in addition, and wire rope grip rope phenomenon can not take place, and cable wire end is fixed in the roller bearing by anchor fitting, and more change steel rope is very convenient.Unit design is reasonable, durable in use, safe and reliable, freedom from repairs, can be widely used in the anti-slide braking of no locomotive standing vehicle on the rail yard, loading and unloading vehicle and garage maintenance vehicle.

Technical solution of the present utility model: a kind of rolling stock Extension Spring-type steel rope is prevented the slide drg, comprises the anti-device assembly (16) that slips of steel rope, and the external end head of the steel rope (4) on the steel rope anti-slide device assembly (16) is connected with extension spring (7).

The left end of the housing (1) of described steel rope anti-slide device assembly (16) is shaped on bayonet socket (5), between front and back two wallboards of housing (1) right-hand member roller bearing (2) is housed, one end of roller bearing (2) is shaped on ratchet (6), and ratchet (6) is positioned at the outside of housing (1) front wallboard, ratchet (8) is installed on two wallboards of housing (1) front and back by ratchet fuse (9), and ratchet (8) is positioned at the outside of housing (1) front wallboard, and makes ratchet (8) and ratchet (6) engagement; Free wrench (3) is equipped with in the outer rear end of the outstanding housing (1) of roller bearing (2), and steel rope (4) is wrapped in before and after the housing (1) on the roller bearing (2) between two wallboards, and the inner termination of steel rope (4) is fixed on the roller (2).

Described extension spring (7) is a spiral tension spring, and its inner is connected with the outer end of steel rope (4), and the outer end is shaped on hook (15).

The position of described roller bearing (2) lay winding wire ropes (4) is a hollow core structures, and its hollow position radially is shaped on steel rope perforation (14), interior cored axle (10); Mandrel (10) axially is shaped on internal thread hole (11) and unthreaded hole (19), radially is shaped on through hole (12), and the perforation mutually of internal thread hole (11), unthreaded hole (19) and through hole (12), and the outer end of internal thread hole (11) is equipped with bolt (13); The inner termination of steel rope (4) is passed the steel rope perforation (14) on the roller bearing (2), through hole (12) back on the mandrel (10) is fixed on the roller (2) by bolt (13).

Advantage that the utility model compared with prior art has and effect:

1, the utility model steel rope external end head connects extension spring, and the phenomenon by tension spring buffering wheel lineoutofservice signal pull when the displacement of rim brake opposite sense suddenly increases prevents wire cable rupture;

2, the utility model steel rope inner termination is fixed in the roller bearing by anchor fitting, and more change steel rope is very convenient;

3, the utility model ratchet and steel rope winding position thoroughly isolates, and wire rope grip rope phenomenon can not take place;

4, the utility model free wrench is fixed on the roller bearing, does not need other strap wrenches during operation, and is easy to use, alleviated labor intensity of operating personnel.

5, reasonable, durable in use, safe and reliable, the freedom from repairs of the utility model unit design can be widely used in the anti-slide braking of no locomotive standing vehicle on the rail yard, loading and unloading vehicle and garage maintenance vehicle.
