Abstract
The utility model provides a track locking device, mainly comprising two locking pieces. The central portion of each locking piece is spacedly provided with outwardly-extending flanges. The flanges are provided with concentric pinholes. The flanges of the two locking pieces are matched with each other and are cooperatively connected via a pin in the pin hole. The locking piece at one side is provided with a screwed hole. A bolt passes through the screwed hole to press against the other locking piece. Such a structure is characterized in that hinged connection is formed by the two locking pieces via the pin.
Description
Technical field
The utility model relates to a kind of latching device, particularly a kind of track latching device that is applied in the rail transport.
Background technology
What track transported is widely used, and for the safety that guarantees that rail vehicle goes in orbit, particularly rail vehicle is ridden up to certain restriction, generally can the track latching device be set at important position, thereby stop rail vehicle, and it can't be passed through.Existing track latching device generally all is the derby that a spill is set, the form fit of its depression and track, and tapped through hole is set in the bottom of depression, through bolt that recessed blocks is fixing in orbit.There are following two shortcomings in this track latching device, and at first install and must install from the track broken end, if the track broken end is bigger with the locked position distance, need be with the slippage always of track latching device to locked position, installing/dismounting is inconvenience very; Secondly because bolt directly contacts with track, excessive coupling mechanism force will cause certain infringement to track, thereby have influence on the fluency that rail vehicle orbits.
The utility model content
The purpose of the utility model is to provide a kind of need not to install from the track broken end for the deficiency that solves above-mentioned technology, can track do not caused damage, and safe and reliable track latching device.
In order to achieve the above object, the utility model institute design-calculated track latching device, it mainly is made up of two staies; The middle part of stay is interval with outwardly directed flange; On flange, be provided with concentric pin shaft hole, the flange of two staies cooperatively interacts, and is connected through the bearing pin that is arranged in the pin shaft hole; On a side stay, be provided with tapped bore, bolt passes the stay that tapped bore props up another sheet.The characteristics of this structure are that two staies form the hinge connection through bearing pin, the bottom opening adjustable size joint that stay forms, thus install from the optional position of track easily.The horizontally set bolt is set simultaneously, makes Clamping force act on the side of track, can the application end face of track not damaged.
Further scheme is that the bottom of described stay is provided with inside ennation, the shape of this ennation and the form fit of track.Thereby reaching locking back track latching device can not make this track latching device be installed in when using on the rail vehicle and can play certain anti-rollover protective effect because of external force or other extraordinary circumstances from the clear generation that track comes off.
Scheme further is that the angle that described flange and stay intersect is 90 °, makes the track latching device perfectly to cooperate with track.
The utility model resulting track latching device, reasonable in design has been overturned latching device in the past provides coupling mechanism force through bolt and track direct contact structural pattern; Actv. has been protected track; It is safe and reliable to have locking, easy installation and removal, and install the optional position; Plug and play, the characteristics that service efficiency is high.

The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
Embodiment 1:
Like Fig. 1, the track latching device that present embodiment is described, it mainly is made up of two staies 1, and the middle part of stay 1 is interval with outwardly directed two flanges 2, and the thickness of distance at interval and flange 2 equates.On flange 2, be provided with concentric pin shaft hole 3; The flange 2 of two staies 1 inserts free-running fit each other; And be connected through the bearing pins 4 that are arranged in the pin shaft hole 3, on a side stay 1, being provided with tapped bore 5, bolt 6 passes the stay that tapped bore 5 props up another sheet.The bottom of described stay 1 is provided with inside ennation 7, the form fit of the shape of this ennation 7 and track 8.Described flange 2 is 90 ° with the angle that stay 1 intersects, and makes the track latching device perfectly to cooperate with track 8.
During use; Earlier bolt 6 is screwed out from tapped bore 5; The bottom of two staies 1 is opened up into maximum angle, then the track latching device is placed on the track 8, again bolt 6 is screwed in tapped bore 5; And make it to withstand the stay 1 of opposite side, be installation after making the bottom of two staies 1 that track 8 is clamped.Reverse aforesaid operations gets final product during dismounting.
Claims (3)
1. track latching device; It mainly is made up of two staies, it is characterized in that the middle part of stay is interval with outwardly directed flange, on flange, is provided with concentric pin shaft hole; The flange of two staies cooperatively interacts; And be connected through the bearing pin that is arranged in the pin shaft hole, on a side stay, being provided with tapped bore, bolt passes the stay that tapped bore props up another sheet.
2. track latching device according to claim 1 is characterized in that the bottom of described stay is provided with inside ennation, the shape of this ennation and the form fit of track.
3. track latching device according to claim 1 and 2 is characterized in that the angle that described flange and stay intersect is 90 °.
