Abstract

The utility model discloses a rapid joint for rails, which is characterized in that the rapid joint comprises at least two bases, a front splint and a rear splint, wherein the base is fixedly connected with the front splint to form one whole body, the base is provided with a fixing seat, the fixing seat is provided with a fixing device, and the rear splint is fixed at one sides of the rails by the fixing device. After a rail splint is replaced by the rapid joint for the rails, rapid connection of two short rails can be realized, and the connected rails have smooth joints without a malposition phenomenon so that the stability of a vehicle in the transporting process is improved, and the transporting process is safer; and meanwhile, connecting holes do not need to be arranged on the short rails which are cut off, so that the working time of cutting the rails is saved. The rapid joint for the rails has a simple structure so that bolts do not need to be inserted in the connecting holes in the using process; and when in use, the rapid joint is convenient and reliable to fasten, therefore, not only the labor intensity of workers is reduced, but also the working efficiency of rails connection is greatly improved.

Description

Track snap joint

Technical field

The utility model relates to the linkage of a kind of track and track, can realize the joint that is connected fast between the track that is cut under particularly a kind of mine and the track.

Background technology

At present normally realize being connected between the track of down-hole and the track by the road clamping plate.Two ends have connecting hole on the road clamping plate, and the connecting hole correspondence on this connecting hole and two tracks that need to be connected is connected two tracks with the road clamping plate by connecting bolt then.Though this connected mode is simple, reliable, only hold whole rail level with both hands and be suitable for, and down-hole track commonly used is an irregular track of end face two.Because the reason of haulage device, the track of full-length is subjected to the influence of appointed conditions such as cage toward the down-hole transportation time at present, and transportation is difficulty comparatively, so numerous applying units has only the track one with full-length to be truncated into two, transport the down-hole to cage again after becoming the short track of length.The mode of blocking usually is oxygen welding cutting, this just formed all short rail one ends neatly, the other end has welding slag and cross section not too smooth, simultaneously also will with oxygen welding cut end cut out match with the road clamping plate, wear the connecting hole that fastening bolt is used.Because the gas welding cutting accuracy is lower, cannot say for sure to demonstrate,prove the positional precision of connecting hole, on the track cut end welding slag is arranged again simultaneously, this just makes the clamping plate of attaining the Way be difficult to realize the smooth-going connection of interorbital, is prone to non-greatly promptly little, the rail connection in track and interorbital shrinkage joint and is prone to inconsistent phenomenon one high and one low, the first from left right side.

Summary of the invention

The purpose of this utility model is a kind of easy to connect, easy to operate, safe and reliable track snap joint of design.

Realize that scheme of the present utility model is: a kind of track snap joint is characterized in that described snap joint comprises at least two bases, a front plate and a rear plate; The affixed formation one of described base and front plate, base is provided with holder, and holder is provided with fastening devices, and rear plate is fixed in a side of track by fastening devices.

The utility model replaces the quick connection that can realize two short rails behind the road clamping plate, and the rail joint after the connection smooth-going, inconsistent phenomenon can not appear, the stability of vehicle transport process is improved, transportation is safer.Simultaneously, the short rail after the cut-out no longer needs to cut out connecting hole, saves the man-hour of track cutting; This device the utility model is simple in structure, need not remove to wear bolt to connecting hole in the use, and fastening convenience, reliable during use when reducing labor strength, has increased substantially the work efficiency that track connects.

Description of drawings

Fig. 1 is structural representation of the present utility model, and Fig. 1 analyses and observe the B-B place of position at Fig. 2;

Fig. 2 is the vertical view of the A-A position of Fig. 1;

Number in the figure: 1 base, 2 front plates, 3 tracks, 4 rear plates, 5 check nuts, 6 fastening bolts, 7 holders, 8 sleepers, 9 shrinkage pools, 10 strengthen the back of the body, 11 grooves.

The specific embodiment

Referring to Fig. 1, deck includes base 1 in the present embodiment, the cross sectional shape of one end of base 1 is a hook solid, the top of crotch and front plate 2 affixed formation one, the other end of base 1 is provided with holder 7, and the fastening devices that is arranged on the holder 7 comprises fastening bolt 6, holder 7 is provided with the screw that matches with fastening bolt 6, the fastening bolt 6 that passes screw holds out against a side at track 3 with rear plate 4, and the front plate 2 of track 3 opposite sides and rear plate 4 are finished the joint of track 3 together.On the fastening bolt 6 check nut 5 can be set, to prevent in use loosening of the utility model.Referring to Fig. 2, front plate 2, rear plate 4 have groove 11 at the middle part with track 3 applyings, the back side of groove 11 correspondences, be provided with the reinforcement back of the body 10 of projection, during use, groove 11 and track 3 junction correspondences, the welding slag when making cutting does not influence the applying of clamping plate and track 3, strengthens being provided with of the back of the body 10 simultaneously and guarantees intensity of the present utility model and safe handling.Below the joint of the track 3 that need connect, sleeper 8 can be set, the utility model in use, base 1 splits two sides at sleeper 8, spacing between two bases can be the width of sleeper 8, can guarantee the utility model stability in use more effectively like this.The position of the back side of rear plate 4 and fastening bolt 6 correspondences is provided with shrinkage pool 9, in use can not be subjected to displacement between assurance fastening bolt 6 and the rear plate 4.
