Abstract
The utility model relates to a heavy track, in particular to a track joint which is convenient to adjust a track. The technical problems whihc are needed to be solved are that a seamless track which is welded in a long distance generates fracture when the air temperature reduces, the shrinkage of the rack can not be detected and is not convenient to adjust, a traditional track joint has big impact, and the joint is easy to be crushed. The technical scheme is that the track joint is convenient to adjust the track, two segments joints which are mutually matched are lapped to form a whole track tread surface, a plurality of round holes are arranged on an I-shaped concave surface of a track junction, a fish plate is arranged on the round holes, and connecting holes are arranged on a corresponding position of the fish plate, and the fish plate and the track are connected through a bolt. A connecting hole of the fish plate is an oval shape. The heavy track is substantially used for the tracks of driving carts.
Description
Technical field:
The utility model relates to a kind of heavy track, particularly a kind of rail joint of being convenient to the track adjustment.
Background technology:
Metallurgy industry adopts the exothermic welding technology to the big Car Track of driving a vehicle more at present, and the primary standard track is welded into the long track of a Gent.But there is following problem: the area of the temperature jump when changing for season, cause the rapid contraction of rail easily, the shrinkage joint that track does not have again to reserve compensates, and fracture very easily takes place.And long do not have expansion joint or conventional rails joint unreasonable apart from continuous welded rail track, make rail not have the function that self adjustable track expands with heat and contract with cold.The amount of expanding with heat and contract with cold of track also can't be detected, and can not in time carry out online adjusting, thereby cause the track breaking state uncontrollable.Chinese patent 200620022518.6 discloses a kind of " sound-deadening damping rail joint ", and the joint end face is the coupling on inclined-plane.This track uses on trolley track, and track length is shorter, and track is installed on the driving car body that the base surface situation is better, distortion is little.This syndeton is difficult to avoid rail joint difference of height to occur and track moves the defective that dislocation appears in the back joint, causes the friction of joint track and wheel rim serious.Simultaneously its for long distance, install the base surface difference of height change (as the distortion of factory building pillar, vibration greatly in addition the phenomenon of sinking) adaptability for working condition not strong.Chinese patent 97207297.7 and Chinese patent 93208731.0 rail joint that openly the concavo-convex end face of dihedral mates and rail level facade left and right sides L mates respectively.These two kinds of joint processing are difficulty relatively, and expense is big, and its connection simultaneously generally all will compress track, does not possess basically also just can not to realize the effect of the online timely adjustment of track as the instrument of observation track stroke.
The utility model content:
The purpose of this utility model provides a kind of rail joint that track is adjusted of being convenient to.The utility model technical issues that need to address are, solve generation fracture and the track amount of contraction of long distance welding continuous welded rail track when temperature reduces and can't detect that inconvenience is adjusted and the conventional rails joint impacts greatly, the problem of the easy conquassation of joint.
Technical solutions of the utility model are: a kind of rail joint of being convenient to the track adjustment, form a complete track tread by match each other step overlap joint of two sections joints, and in the rail connection I-shaped concave surface is respectively established a plurality of circular holes, splice bar is installed thereon, and have connecting hole in the splice bar relevant position, by bolt splice bar is connected with track.Described splice bar connecting hole is oval.
The effect of the utility model technology is: 1) can reflect the amount of contraction of track in real time, according to the timely online adjustment track of temperature Change, reduce track and shrink fracture defect; 2) the track connector has retractility and flexible scope is big, and amount of contraction can reach about 30mm; 3) have operate steadily, damping, noise abatement; Can effectively protect the crane wheel, improve wheel life.4) after the rational heat treatment, track connector tread is difficult for conquassation.
Description of drawings:
Accompanying drawing is the utility model structural representation
Among the figure: 1-track, 2-step, 3-splice bar, 4-bolt.
The specific embodiment:
With reference to accompanying drawing, a kind of rail joint of being convenient to the track adjustment, form a complete track tread by two sections joints step 2 overlap joint that matches each other, and in the rail connection I-shaped concave surface is established 4 circular holes, splice bar 3 is installed thereon, and have connecting hole in splice bar 3 relevant positions, by bolt 4 splice bar 3 is connected with track 1.Described splice bar 3 connecting holes are oval.
Be that stage portion is carried out quenching heat treatment to the tread after the track processing again, the depth of quenching is greater than 10mm, more than the hardness HB300; Bolt is not wanted tension, will guarantee after the assembling that the play movement can stretch and be not less than the change amount of 20mm.
Claims (2)
1, a kind of rail joint of being convenient to the track adjustment, it is characterized in that: form a complete track tread by match each other step overlap joint of two sections joints, and in the rail connection I-shaped concave surface is established a plurality of circular holes, splice bar is installed thereon, and have connecting hole in the splice bar relevant position, by bolt splice bar is connected with track.
2, a kind of rail joint that track is adjusted of being convenient to according to claim 1, it is characterized in that: described splice bar connecting hole is for oval.
