Description

The poor height adjustment instrument of the mutual hook of railway freight-car coupler
Technical field
The utility model relates in the operation of goods train application and maintenance the poor a kind of instrument of the mutual hook of hitch of processing of adjusting.
Background technology
" skill rule " regulation: interconnective hitch in car team " hook is poor mutually " must not surpass 75mm, while surpassing, just may make hitch in train operation, occur that vertical direction breaks off relations.Cause " hitch separates automatically " accident, affect traffic safety.And process " hook the is poor mutually " fault that transfinites in the past, generally needed 3 people to transport sleeper head, jack, crowbar etc. to 4 people, due to the jack lift when inadequate, also to pad several sleeper heads and just can reach top lifting height, the line of centers of sleeper head, jack can not be overlapped,, there is certain potential safety hazard in easy avalanche during operation.
Summary of the invention
The purpose of this utility model is: design the poor height adjustment instrument of the mutual hook of a kind of railway freight-car coupler, make to be listed as inspection person in the operation of freight train application and maintenance safety, to adjust mutual hook easily and efficiently poor.
Realize that the technical scheme that the utility model purpose adopts is: it is comprised of hitch positioning seat, left-handed double end stud, adjustment swivel nut, dextrorotation double end stud, supporting seat, a hole is arranged in the middle of supporting seat, above the hitch positioning seat, two ends are respectively equipped with locating dowel pin, and a hole is below arranged; Adjusting swivel nut is the pipe of a hollow, and outer middle part is equipped with an operation handwheel, and its two ends endoporus is respectively minus thread and right-hand screw thread; Left-handed double end stud one end is screwed on the silk hole below the hitch positioning seat, the other end adjustment swivel nut that spins; Dextrorotation double end stud one end is screwed on the silk hole above supporting seat, the other end adjustment swivel nut that spins.
The locating dowel pin at hitch positioning seat two ends is two bolts, and there are two screws at hitch positioning seat two ends, and two bolts screw out below the hitch positioning seat.
Three positioning pawls that are uniformly distributed along the circumference on the lower plane of supporting seat, when preventing rotation hand wheel, supporting seat rotates with respect to ground.
good effect of the present utility model is: with use top pick, sleeper head, lengthen the mutual hook difference method of backing plate adjustment and compare, have that instrument is lightweight, lift is large, easy to carry, simple to operate a, effect safely and efficiently, during adjustment, suitably handwheel is adjusted in rotation, tool length is adjusted to suitable height, be placed on lower gib head below, and the both sides of gib head are stuck between two locating dowel pins, handwheel is adjusted in rotation, to hang down gib head and adjust to suitable height, between hook body and hook joist, put into and adjust backing plate or brake shoe drill, handwheel is adjusted in rotation, the length of shortening instrument, the taking-up instrument, complete the poor adjustment of mutual hook, not there will be any potential safety hazard, people can complete the adjustment with the hitch height of carrying of instrument, can quick adjusting hitch height, shorten row inspection production time, reduce row inspection operation labor intensity.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, it is comprised of hitch positioning seat 1, left-handed double end stud 2, adjustment swivel nut 3, dextrorotation double end stud 5, supporting seat 6, a hole is arranged in the middle of supporting seat 6, the locating dowel pin at hitch positioning seat 1 two ends is two bolts 7, at hitch positioning seat 1 two ends, open two screws, two bolts 7 screw out below hitch positioning seat 1, a hole is arranged below hitch positioning seat 1; Adjusting swivel nut 3 is the pipe of a hollow, and outer middle part is equipped with an operation handwheel 4, adjusts swivel nut 3 two ends endoporus and is respectively minus thread and right-hand screw thread; Left-handed double end stud 2 one ends are screwed on the silk hole below hitch positioning seat 1, and the other end spins and adjusts swivel nut 3; Dextrorotation double end stud 5 one ends are screwed on the silk hole above supporting seat 6, and the other end spins and adjusts swivel nut 3; When preventing rotary manipulation handwheel 4, supporting seat 6 is with respect to the ground rotation, and three positioning pawls 8 are uniformly distributed along the circumference on the lower plane of supporting seat 1.
The method of operation of this instrument is: at first the positioning pawl of supporting seat 6 bottoms 8 is pricked on ground or railway roadbed rock ballast, rotary manipulation handwheel 4, adjust to suitable height by tool length, is placed on lower gib head below, and the both sides of gib head are stuck between two dowel bolts 7, rotary manipulation handwheel 4, will hang down gib head and adjust to suitable height, between hook body and hook joist, put into and adjust backing plate or brake shoe drill, rotary manipulation handwheel 4, the length of shortening instrument, the taking-up instrument, complete the poor adjustment of mutual hook.
