Abstract
The utility model discloses an anti-unhooking device for a locomotive draw gear. The anti-unhooking device for the locomotive draw gear is characterized by comprising a T-shaped positioning bolt, a sleeve, a locking bolt and an inserting plate. The sleeve is welded with the main body of a draw gear to form a whole. The T-shaped positioning bolt is arranged in the sleeve. Holes are formed both in the T-shaped positioning bolt and the sleeve. The locking bolt passes through the holes. A bolt hole is formed at the tail end of the locking bolt. The inserting plate is connected with the locking bolt through the bolt. The anti-unhooking device for the locomotive draw gear has the advantages that problems of accidental unhooking of the draw gear during the traveling of a locomotive and unhooking accidents due to the fact that person outside the road lifts the draw gear are avoided. Safe traveling control degree of the locomotive is improved.
Description
Technical field
The utility model relates to a kind of dropping resistance device for locomotive car coupler.
Background technology
High mouthful of iron ore bought two in DF8B locomotive in 2008 by oneself, undertaking the transportation burden of high mouthful of iron ore pellets shipping and rock head team military supplies.Two DF8B locomotive couplers are comprised of coupler body, hook tongue, coupler knuckle lock, lower lock pin, lifet lever, hook shadoof etc., have the standard-sized sheet position (220-250mm), unlock position, (110-130mm) three states, the activity that hitch makes progress at locking position, hook lock is 5-22mm in the locking position.Its effect is to guarantee that locomotive is connected and separates with vehicle with locomotive, locomotive normally.The locomotive that separately connects when needs is during with locomotive or locomotive and vehicle, and operating personnel's Hand-held hook shadoof drives lower lock pin by lifet lever and moves up, and coupler knuckle lock is also moved up, and pushes away iron by the hook tongue hook tongue is opened, the separating of realization hitch; When needs connect, under the prerequisite that hitch is opened, promote the hook tongue, push away iron by the hook tongue coupler knuckle lock, lower lock pin are moved down, and then realize being connected of locomotive and locomotive or locomotive and vehicle.Itself has anti creep performance hitch, its anti-jump principle is: when certain reason moves up the car coupler knuckle lock, coupler knuckle lock drives lower lock pin and moves up together, this arrives on the rotary operation anticreep ledge of lockpin hole under the coupler hook body at lock pin top at present, thereby stop coupler knuckle lock to continue to rise, prevent that hitch from opening automatically.
Yet find that in operating process because railroad curve is many, radius of curve is little, line slope is large, and rock seriously the middle hitch junction of travelling, and particularly travels on curve and ramp, or circuit level and gauge rock more serious when bad.Once occured the hitch case accident to occur at steep gradient and bring major safety risks to the operation of locomotive, the problem that therefore solves the hitch anticreep is to realize the effective measures of rolling stock safe operation.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of dropping resistance device for locomotive car coupler, this device not only can stop to occur in the locomotive driving the unexpected unhook problem of hitch, and has prevented that effectively the artificial lancet of personnel causes the unhook accident outside the road, has improved the safety running control degree of locomotive driving.
The technical solution adopted in the utility model is: dropping resistance device for locomotive car coupler, it is characterized in that: comprise T shape fastening screw, sleeve, locking pin, plate, sleeve and coupler body are welded as a whole, T shape fastening screw is positioned at sleeve, be equipped with the hole on T shape fastening screw and the sleeve, locking pin can pass this hole, and the locking pin end is provided with bolt hole, and plate is connected with locking pin by bolt.
The utility model patent is by the repeatedly analytical investigation to the scene, increase a latch in hitch rotation place and block wheel word to realize the hitch locking, in any case it is rocked also can't be automatically-unhooked, when needs are unsnaped gib head, only push safety pin aside and just can mention gib head, make hitch be in opening.Because vehicle is state's iron vehicle rather than provides railway carriage for oneself, so consider at locomotive two ends fabrication and installation hitch anti-drop device.
The dropping resistance device for locomotive car coupler that the utility model provides, the one, it is up to stop the car coupler knuckle lock to continue, thereby plays the effect that prevents that hitch from separating automatically; The 2nd, can effectively prevent non-operating personnel artificially or the effect of unconsciously hitch being proposed out.Not only can stop to occur in the locomotive driving the unexpected unhook problem of hitch, and prevent that effectively the artificial lancet of personnel causes the unhook accident outside the road, the most important thing is to improve the safety running control degree of locomotive driving.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model (part is analysed and observe).
1 is T shape fastening screw among the figure, and 2 is sleeve, and 3 is locking pin, and 4 is coupler body, and 5 is that plate, 6 is bolt.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of dropping resistance device for locomotive car coupler, it is characterized in that: comprise T shape fastening screw 1, sleeve 2, locking pin 3, plate 5, sleeve 2 is welded as a whole with coupler body 4, T shape fastening screw 1 is positioned at sleeve 2, is equipped with the hole on T shape fastening screw 1 and the sleeve 2, and locking pin 3 can pass this hole, locking pin 3 ends are provided with bolt hole, and plate 5 is connected with locking pin 3 by bolt 6.
Because vehicle is state's iron vehicle rather than provides railway carriage for oneself, so consider at locomotive two ends fabrication and installation hitch anti-drop device.This device on probation has prevented from effectively that the rolling stock gib head is expert to sail and unexpected unhook accident occurs because hitch rocks during by location, curve ramp, has increased the locomotive operation safety degree, is worth promoting to other associate organizations or state's iron.
