Abstract

The invention discloses a railway wagon mileage recording device, which belongs to the technical field of railway vehicle devices. The railway wagon mileage recording device comprises a roller device, a transmission device and a counting display device, wherein the roller device comprises a cam, a roller, a pull rod, a support and a regulating mechanism which are connected in sequence; the cam is arranged on a wheel set component of a bogie; the transmission device comprises a flexible shaft, a lever-type rotating plate set and a ratchet transmission mechanism; the lever-type rotating plate set comprises a rotating plate, a shaft sleeve, a positioning screw, a return spring, a buffer spring and a pawl shaft; the ratchet transmission mechanism comprises a ratchet, a pawl, a pawl spring and a snap spring; and the counting display device comprises a driven gear and a counter, wherein the roller is driven to rotate by the cam; the pull rod is driven by the roller to do a vertical reciprocating motion; the vertical reciprocating motion is transferred to the rotating plate through the flexible shaft; and from the lever-type rotating plate set to the ratchet transmission mechanism, a gear is meshed with the driven gear, and the driven gear is coaxial with the counter. According to the railway wagon mileage recording device disclosed by the invention, the cost is low and the installation is convenient; accumulative running mileage data of railway wagons can be accurately provided; and a basis for better estimating the states of the railway wagons is provided.

Description

Railway freight-car mileage record device

Affiliated technical field

The present invention relates to a kind of vehicle servicing unit, especially vehicle mileage record device belongs to rolling stock device technique field.

Background technology

At present, railway freight car accumulative total driving mileage data is a pith that is used for assessing vehicle-state, and during maintenance policy that particularly key components and parts state and decision are adopted on the assessment vehicle, these data are wherein important factors.On the railway freight car mileage record device is not installed at present, can only adopts the mode of fixed interval when making the assessment vehicle reliability, and adopt the strategy of periodic maintenance.Cause so the whole state of the art of vehicle is lacked comprehensively understanding, the vehicle that some state of the art are good simultaneously is parking maintenance also, causes the significant wastage of resource.

Summary of the invention

To the problems referred to above, the present invention provides a kind of railway freight-car mileage record device.

The technical solution adopted for the present invention to solve the technical problems is: railway freight-car mileage record device; Comprise roller devices, gearing, counting display device; Roller devices is made up of cam, roller, pull bar and the support, the governor motion that connect successively; Cam is installed in the wheel of bogie on forming; Gearing comprises flexible axle, lever flap group and ratchet mechanism; Lever flap group is made up of flap, axle sleeve, dog screw, return spring, buffer spring and pawl axis; Ratchet mechanism is made up of ratchet, ratchet, click spring and jump ring; Counting display device comprises follower gear, counter; The cam driven roller rotates, and roller drives the upper and lower to-and-fro movement of pull bar, passes to flap through flexible axle; To ratchet mechanism, gear and follower gear mesh by lever flap group, and follower gear is coaxial with counter.

The invention has the beneficial effects as follows; With low cost, easy for installation, filled up the blank that railway freight-car does not have the mileage record device; Railway freight car accumulative total driving mileage data can accurately be provided, for better assessing vehicle-state and providing the maintenance policy of science that foundation is provided.

Embodiment

Below in conjunction with embodiment the present invention is further specified.

Referring to Fig. 1, railway freight-car mileage record device; Comprise roller devices, gearing, counting display device; Roller devices is made up of cam 1, roller 2, pull bar 3 and the support 4, the governor motion 5 that connect successively; Cam 1 is installed in the wheel of bogie on forming; Gearing comprises flexible axle 6, lever flap group and ratchet mechanism; Lever flap group is made up of flap 7, axle sleeve 8, dog screw 9, return spring 10, buffer spring 11 and pawl axis 12; Ratchet mechanism is made up of ratchet 15, ratchet 14, click spring 16 and jump ring 17; Counting display device comprises follower gear 19, counter 20; Cam 1 drives roller 2 and rotates, and roller 2 drives pull bar 3 upper and lower to-and-fro movements, passes to flap 7 through flexible axle 6; To ratchet mechanism, gear 18 meshes with follower gear 19 by lever flap group, and follower gear 19 is coaxial with counter 20.

Adopt the revolution of mechanical hook-up measuring wheel, and convert out the accumulative total distance travelled in view of the above forming.

Roller devices is installed on the wheel of railway freight-car running part (bogie) on forming, and the vehicle operating hour wheel drives the roller devices motion to rotating, and roller devices drives actuator movement simultaneously, and then drives counting display device registration of vehicle distance travelled.

Flexible axle 6 is convenient to the optional position that counting display device is installed on car body.

To the revolution of composition and the multiple ratio of gear of setting, can write down the distance travelled of different-diameter wheel vehicle through record railway freight-car wheel, simultaneously same wheel taken into full account the influence of factors such as its abrasion state to mileage record.

For realizing above-mentioned purpose, the step that this device comprises has:

A. according to vehicle wheel wheel in forming is selected corresponding ratio of gear to diameter, gear 18 and follower gear 19 position gears are arranged on this ratio of gear respective notch;

B. by vehicle wheel the rotating band moving cam formed 1 is rotated, the rotation through cam 1 makes pull bar 3 do upper and lower to-and-fro movement;

C. the upper and lower to-and-fro movement that produces through pull bar 3 passes to flap 7 through flexible axle 6;

D. being driven with axle sleeve 8 by gearing is fulcrum, and wire rope 13 pulling flaps 7 rotate, and are spacing with dog screw 9; Make ratchet 14 move the distance of a tooth, promote ratchet 15 and turn over a tooth, ratchet 15 driven gears 18 rotate; Axletree whenever circles, and ratchet 15 rotates a tooth, after ratchet 15 rotates certain number of teeth; Through gear 18 and follower gear 19 engagements, the realization counter is walked a word of bit digital last.Flap 7 resets and accomplishes by return spring 10.The pulling over travel of wire rope 13 leans on buffer spring 11 to eliminate.For ratchet 15 is rotated towards a direction, prevent its reversing by jump ring 17.
