Description

Dual-mouth auxiliary hook railway switch hook lock device

Technical field

The utility model relates to the railway operation safety safeguard, is specially adapted to the locking of railway switch.

Background technology

Hook lock device is with a kind of instrument of railway switch tongue with the mutually closely connected locking of stock rail, and the user mode of track switch is placed under the monitoring of handling the driving personnel, guarantees safe train operation.At present, the patent No. of using on China railways is 02243282.5 interior external lock railway switch hook lock device, though all can reach the use needs of locking track switch on structure, function and bearing load, also has the locking stability problem in the middle of using.Behind the switch locking, repeatedly under the sharp pounding effect, impel auxiliary hook to swing at train, make it be difficult to keep concentric with locknut, the torsional forces of auxiliary hook acts on locknut, and the turn of locknut on hook body screw rod is obstructed, and causes the difficulty that locks or unblank.

Summary of the invention

The purpose of this utility model provides a kind of dual-mouth auxiliary hook railway switch hook lock device, and upper latch notch is used for the locking of a large amount of common track switches, and following bayonet socket then is applicable to the track switch of the various different structures of railway---the locking of particularly large-scale track switch or special-shaped track switch.Bayonet socket and stock rail flange of rail chucking stop the extruding of the torsional forces of auxiliary hook to locknut, and traffic safety is guaranteed in the flexibility that maintenance locks or unblanks.

The technical solution of the utility model is achieved in that dual-mouth auxiliary hook railway switch hook lock device, by multiple gib head, hook body, dual-mouth auxiliary hook, locknut, keying key, add torque wrench and form, multiple gib head and hook constitute main hook as one, the end of hook body is the leading screw structure, and it is trapezoidal multiple hook that gib head is made section.Locknut places in the dual-mouth auxiliary hook stack shell, and be contained on the leading screw with its internal thread spiral shell, by the rotation that opens and closes key, locknut front and back on leading screw are moved, the dual-mouth auxiliary hook is sleeved on one's body the hook, dual-mouth auxiliary hook sidewall is provided with locating hole, be shaped on the female lock and the corresponding outer circular slide way of dual-mouth auxiliary hook locating hole, alignment pin is installed in the locating hole of dual-mouth auxiliary hook and inserts in the chute of locknut, the interior six side's side opening collet heads that open and close key and six square nut heads of locknut are suit mutually, be rotated in the forward the keying key lock, locknut drives the dual-mouth auxiliary hook and moves forward on leading screw, makes upper latch notch or following bayonet socket on the dual-mouth auxiliary hook sting the tight track switch stock rail flange of rail, point tongue is locked, reverse rotation opens and closes key, and locknut drives auxiliary hook and recesses the track switch stock rail, and track switch is carried out release.Dual-mouth auxiliary hook stack shell tail end is shaped on two ear seats of symmetry, and a locking hole is respectively arranged on each ear seat; Dual-mouth auxiliary hook head and stack shell are made one, be shaped on a upper latch notch and a following bayonet socket on the face of the auxiliary hook crown, the amount of sucking that upper and lower lip constituted of upper latch notch and shape and the interlock mutually of the common track switch stock rail flange of rail, the recessed gib head end face of the upper lip of following bayonet socket, and the inner face of lower lip is made step, so that contain the stock rail flange of rail of large-scale track switch of card or special-shaped track switch; Be shaped on a locating hole on auxiliary hook stack shell sidewall, be convenient to be connected with locknut with alignment pin, auxiliary hook head center is shaped on a hook body mounting hole.The torque wrench that adds that the centre has perforation is " Y " font; respectively be provided with an inserted link on the head two fork legs; be shaped on bright lockhole on the handle of interstitial hole both sides, with adding torque wrench rotary opening and closing key, after hook lock puts in place; take off key; adding the torque wrench spiral-lock on auxiliary hook stack shell tail end mouth, the bright lockhole that adds on the torque wrench overlaps with locking hole on the auxiliary hook ear seat, installs a bright lock again additional in the hole that overlaps; railway switch is implemented duplicate protection, satisfy the monitoring of driving the track switch influence.

The utlity model has following advantage:

1, the gib head end face at the hook lock device auxiliary hook is shaped on bayonet socket, during locking track switch, and bayonet socket chucking stock rail, strengthened the stability of locking point tongue, simultaneously, eliminated because auxiliary hook is subjected to torsional forces that the train vibrations produce to the extruding of locknut and the worn-out end that turn is obstructed, to lock or unblank convenient, flexible.

2, auxiliary hook crown face is shaped on upper and lower bayonet socket, and upper latch notch is used to tighten the common track switch stock rail flange of rail, and following bayonet socket is used for the locking of large-scale track switch or other special-shaped track switch, applied range.
