Abstract
The utility model disclose a clearance adjusting device of a tread cleaner used for rail vehicles, and the device comprises a toothed rack, a bolt, a bolt cap, a spring and a bushing; the toothed rack can be arranged inside a slide groove of a piston rod of the tread cleaner, the toothed rack can slide along the axial direction of the piston rod inside the slide groove, both the bolt cap and the bushing are connected with the mounting hole of the main body of the tread cleaner, the bolt is matched with the bushing in a sliding way, the spring is clamped between the inner end face of the bolt and a bumping shoulder of the bolt, the top end of the bolt is meshed with the tooth of the toothed rack. The clearance adjusting device of the tread cleaner has the advantages of simple structure and capability of realizing flexible clearance adjustment without jamming.
Description
Technical field
The utility model relates to a kind of wheel tread swabbing pig of rail vehicles.
Background technology
Along with improving constantly of train running speed, tread cleaner being improved the effect of wheel has higher requirement, need the tread cleaner brake shoe can in time efficiently clean wheel, wherein just brake shoe and wheel tread are had the fixed interval (FI) scope and proposed requirement, also just need have adjust the clearance function flexibly.And at present domestic used tread cleaner adopts leading screw, stroke adjustment spring installation to carry out adjust the clearance, though this mechanism can make brake shoe and between-wheel spacing remain on certain limit, and complex structure, adjust the clearance is dumb, catching phenomenon very easily occurs.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and adjust the clearance is the tread cleaner lash adjusting device flexibly.
In order to achieve the above object, the technical solution of the utility model is: a kind of tread cleaner lash adjusting device, comprise tooth bar, latch, plug pin cap, spring and lining, tooth bar can be contained in the chute of piston rod of tread cleaner, tooth bar can be in chute along piston rod endwisely slip the mounting hole load of the body of plug pin cap and lining and tread cleaner, latch and lining bearing fit, Spring Card is between the shoulder block of plug pin cap inner end surface and latch, and the latch head can mesh with the tooth of tooth bar.
After adopting said structure,, cancelled the screw mandrel gap adjusting structure owing to adopt latch, rack structure, therefore simple in structure; And the engagement of latch and tooth bar can be carried out adjust the clearance neatly, is not prone to catching phenomenon.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing does explanation in further detail to the utility model.
Fig. 1 is the installing condition structural representation of tread cleaner lash adjusting device of the present utility model;
Fig. 2 is the I portion partial enlarged view of Fig. 1;
Fig. 3 is the cutaway view of Fig. 2 along the A-A line.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of tread cleaner lash adjusting device of the present utility model, comprise tooth bar 1, latch 2, plug pin cap 3, spring 4 and lining 6, tooth bar 1 can be contained among the chute 8-1 of piston rod 8 of tread cleaner, tooth bar 1 can endwisely slipping along piston rod 8 in chute 8-1, the mounting hole 7-1 load of the body 7 of plug pin cap 3 and lining 6 and tread cleaner, latch 2 and lining 6 bearing fits, spring 4 is stuck between the shoulder block 2-2 of plug pin cap 3 inner end surfaces and latch 2, and latch 2 heads can mesh with the tooth of tooth bar 1.
Shown in Fig. 2,3, influence the tooth engagement of latch 2 heads and tooth bar 1 in order to prevent latch 2 from rotating, the utility model also comprises guide ring 5, guide ring 5 is contained among the mounting hole 7-1 of body 7 of tread cleaner, guide ring 5 endoporus have plane 5-1, the pin of latch 2 has cooresponding flat gesture 2-1 on one's body, latch 2 pin body and guide ring 5 endoporus bearing fits.Certainly, also can not adopt plane 5-1 and flat gesture 2-1, at this moment latch 2 heads can not established the inclined-plane, and the tooth of tooth bar 1 simultaneously adopts big inclined-plane, and another side adopts vertical surface, slip into from the inclined-plane of the tooth of tooth bar 1 to guarantee latch 2 heads, in the vertical surface self-locking of tooth.
Shown in Fig. 2,3, circumferentially spacing in order to make guide ring 5, prevent that further latch 2 from rotating, guide ring 5 peripheries have protruding 5-2, and protruding 5-2 is contained among the draw-in groove 7-1-1 of body 7 mounting hole 7-1.Certainly, also can not adopt protruding 5-2.
As shown in Figure 1, 2, invade, also comprise rubber bellows 9, rubber bellows 9 one ends and latch 2 loads, the other end and plug pin cap 3 loads in order to prevent dust.
As shown in Figure 1, 2, 3, in the utility model when work,, the piston rod 8 of tread cleaner stretches out and drives tooth bar 1 and travel forward, and the tooth bar 1 right flank of tooth acts on latch 2 lower ends, and latch 2 is along lining 6 upward movements, spring 4 pressurizeds.Along with the increase of abrasion, piston rod 8 continues to stretch out to the right, and latch 2 slips over and resets under the effect of spring 4 behind first flank of tooth of tooth bar 1 and tooth bar 1 upper groove meshes.Along with piston rod 8 proal distances constantly increase, the tooth on latch 2 lower ends and the tooth bar 1 meshes in succession.When piston rod 8 resets, piston rod 8 drives brake shoe 10 and leaves wheel, this moment, the left flank of tooth of latch 2 lower ends and tooth bar 1 formed self-locking, make the tooth bar 1 can not be with piston rod 8 to left movement, when the chute 8-1 right-hand member on the piston rod 8 and tooth bar 1 right-hand member offset, piston rod 8 stop motions, distance thereby the retraction of control plunger bar 8 resets, make the distance between brake shoe 10 and the wheel remain on fixed range, reach the purpose of adjusting play neatly.
