Abstract

An anti-abrasion shaft sleeve device consists of an anti-abrasion shaft sleeve, a lock nut and a lock clamp, wherein the anti-abrasion shaft sleeve device is mounted on a lock hook of a railroad switch and fixedly embedded into an expanded round hole on the lock hook. When the device is in use, a pin shaft penetrates into the round hole of the anti-abrasion shaft sleeve on the lock hook; the pin shaft rotates with the anti-abrasion shaft sleeve under the action of the lock hook, so that the anti-abrasion shaft sleeve does not rotate with the lock hook; as the anti-abrasion shaft sleeve embedded in the lock hook is made of abrasion-resistant material, and the contact areas between pin holes are enlarged, the anti-abrasion shaft sleeve device is very durable and abrasion-resistant, and can be mounted on the lock hook which is discarded due to the abrasion of the lock hook hole, or the pin holes on other connecting parts of the railroad switch, is suitable for re-utilization, and greatly reduces the production and maintenance costs; and after a long-term use, abrasion gap is produced between the round hole of the anti-abrasion shaft sleeve and the pin shaft, the lock hook device can be set in an excellent use state as long as the anti-abrasion shaft sleeve is conveniently replaced.

Description

A kind of anti-abrasion shaft sleeve device

Technical field:

A kind of anti-abrasion shaft sleeve device is suitable for using on the latch hook of the outer locking track switch of railway speed increase especially, belongs to the interconnection technique field of Structural Hardware.

Background technique:

At present, outside railway on the track switch of locking, be used for the latch hook of locking track switch normally to penetrate to connect in the circular hole on latch hook and use through bearing pin; When moving at latch hook, this Placement directly produces abrasion between circular hole and the bearing pin, after long-time the use, because wearing and tearing can make circular hole on the latch hook become big ovalize, bearing pin attenuates; Produce spacious moving between the two, cause point tongue and stock rail not closely connected, switch indication can not normally show; Overcome above-mentioned defective at present and often need latch hook more be changed, even bearing pin all to more change, cause great waste; Influence the normal use of equipment, bring unsafe factor to driving.

Summary of the invention:

The purpose of the utility model provides a kind of anti-abrasion shaft sleeve device, and can be installed on the pin-and-hole of outer locking switch lock, point lock hook or on the pin-and-hole of other connection parts, not only can increase the work working life of track switch latch hook, and also very wear-resisting.After long-time the use, only need the anti-abrasion axle sleeve on the latch hook is more changed, can make latch hook be in good user mode again, and change simple to operation in case produce wearing clearance.This prevents abrasion shaft sleeve device except can on new latch hook, installing, and also can be installed on the latch hook of scrapping because of the hook lock abrasion deformation it is reused, and has greatly improved economic benefit, has reduced the production maintenance cost.

The utility model is made up of anti-abrasion axle sleeve, locking nut, locking card.The cylindrical body cylindrical of anti-abrasion axle sleeve is smooth surface or screw-like, and its termination was provided with screw thread when cylindrical body was smooth surface.Cylindrical middle part is provided with circular groove, and the periphery in the circular groove is provided with 2-3 the evenly oil seepage hole of branch, is convenient to oiling and uses.Pin-and-hole during installation that latch hook is original enlarges, and its diameter is identical with the diameter of anti-abrasion axle sleeve cylindrical body cylindrical, and the circular-hole internal-wall after the expansion can be smooth surface or screw-like according to the cylindrical structure of anti-abrasion axle sleeve.Anti-abrasion axle sleeve is bumped in the circular hole after enlarging on the latch hook, is fixed.During use bearing pin is penetrated in the circular hole of anti-abrasion axle sleeve on the latch hook;, latch hook rotates when moving through producing abrasion between bearing pin and the anti-abrasion axle sleeve; Do not rotate between the circular hole of anti-abrasion axle sleeve and latch hook; Because the anti-abrasion axle sleeve that is installed on the latch hook is to adopt more wear-resisting material to process, increased the area of contact between the pin-and-hole simultaneously again, therefore unusual durable wear.After long-time the use,, only need the anti-abrasion axle sleeve on the latch hook more changed and to make latch hook be in good user mode again if produced the abrasion gap between anti-abrasion axle sleeve and the bearing pin.

Described anti-abrasion axle sleeve 1 is convex form; Be provided with the smooth circular hole 1-2 of a perforation in the cylindrical body 1-1 of axle sleeve; The diameter of circular hole is identical on Circularhole diameter and the old-fashioned latch hook, and the cylindrical of cylindrical body 1-1 is smooth surface or screw-like, and outside diameter is identical with Circularhole diameter after latch hook enlarges; Cylindrical middle part is provided with circular groove 1-3; Be provided with 2-3 the evenly oil seepage hole 1-4 of branch in the circular groove 1-3, the oil seepage hole 1-4 and the circular hole 1-2 of anti-abrasion axle sleeve connect, and its termination was provided with screw thread 1-5 or jump ring groove when the cylindrical body 1-1 of axle sleeve was smooth surface.

Described locking nut and locking card all are the parts of NBS, with the supporting use of anti-abrasion axle sleeve.

The advantage of the utility model: this anti-abrasion shaft sleeve device can be used on the pin-and-hole of why not same model track switch connection part in office; Effectively reduce the wearing and tearing between the pin-and-hole; The stability of assurance equipment and reliability; And can utilize once more because of pin-and-hole becomes the latch hook of scrapping greatly, improved economic benefit, greatly reduce the production maintenance cost.Should not only change easily simple but also long service life, not easy to wear by anti-abrasion device; Only need to change the anti-abrasion axle sleeve on the latch hook in case produce wearing and tearing; Can make latch hook device be in good user mode again, increase substantially the working life of latch hook, effectively guarantee traffic safety.
