Abstract
The utility model relates to the coal mine machine equipment field, in particular to a screw-in limit dumbbell component for a scraper conveyer. In prior art, the middle groove linkage of the middle section of the mine coal scraper conveyer has mounting and operation difficulties, both ends of the dumbbell have unreasonable structures, and the stress distribution of the limit block is uneven. The screw-in limit dumbbell component is composed of a dumbbell, a limit block and a clamp spring limit pin. Both ends of the dumbbell are provided with symmetric flat structures relative to the axis of the dumbbell, and a rectangle limit lug boss is arranged on the upper and lower parts of the left end of the dumbbell; an ellipse lug boss is arranged on the outer side of the right end of the dumbbell and is connected with a pored circular shaft. The limit block is in longitudinal and bilateral symmetry, a central through hole is matched with the right end shaft of the dumbbell, an inner side ellipse concave groove is connected with the ellipse lug boss of the dumbbell in matched manner; the clamp spring limit pin is mounted in the circular shaft hole on the right end of the dumbbell. The screw-in limit dumbbell component for the scraper conveyer has reasonable structure, increases the bearing capability, realizes convenient operation and is economical and practical.
Description
Technical field
The utility model relates to the coal mine machinery equipment field, and specifically a kind of slat conveyer is the coupling components between slat conveyer middle part intermediate channel with the spacing component of dumb bells of screw-in.
Background technology
At present, connection between coal mine scraper conveyor middle part intermediate channel, the main external component of dumb bells structure that adopts, its principle of work is to set up vertical connection between intermediate channel with dumbbell, with limiting stopper dumbbell is fixed in the conveyer intermediate channel, live limiting stopper with U type kayser at last, prevent the dumbbell play.This draw bail has following weak point: 1. because the dumbbell two ends all need to use limiting stopper, and the groove of limiting stopper is polygon, caused the installation difficulty of component of dumb bells; 2. the unreasonable structure of dumbbell two ends, the rear portion of two ends cuts little ice in actual use, causes waste of material; 3. the respective outer side edges of polygon boss in the polygon groove of limiting stopper inboard and the dumbbell two ends outside, area of contact is little in actual use, causes distribution of stress inequality, the stress value of limiting stopper excessive, the destruction of easily causing limiting stopper.
Summary of the invention
The purpose of this utility model provides a kind of slat conveyer with the spacing component of dumb bells of screw-in, can overcome the deficiency that has external component of dumb bells draw bail now.
The purpose of this utility model reaches by following technical solution:
Slat conveyer is made of dumbbell, limiting stopper, circlip type locating dowel pin three parts with the spacing component of dumb bells of screw-in.The dumbbell two ends are provided with the flat structure with respect to dumbbell axis symmetry, and left-end flat structure front projection is a D shape symmetrical structure, and a positive stop lug boss is respectively arranged up and down in this termination; Right-hand member flat structure front projection is dolioform symmetrical structure, in this outside, termination an ellipse around boss is arranged, and boss is connected with a circular shaft with holes; Limiting stopper is symmetry up and down, and there is a through hole that matches with dumbbell right-hand member circular shaft at the center, and there is a circle oval-shaped groove inboard; The through hole of limiting stopper is through on the dumbbell circular shaft with holes, and oval-shaped groove matches with the ellipse around boss of dumbbell, and the circlip type locating dowel pin is packed in the hole of dumbbell right-hand member circular shaft.
The positive stop lug boss of described dumbbell (2) left end can be a rectangle, also can be circular.
The utlity model has following advantage:
1. in real work,, can realize quick connection or decomposition between intermediate channel because component of dumb bells can be assembled or dismantle easily.
2. realize the rational deployment of dumbbell structure, with the contrast of same model dumbbell, weight has descended 10%, and material cost can decrease, and makes the usage quantity of limiting stopper (3) and circlip type locating dowel pin (4) reduce 1/2 simultaneously, has reduced more tooling cost.
3. the oval-shaped groove of limiting stopper inboard cooperates with the outside, dumbbell termination ellipse around boss, and area of contact increases, and limiting stopper distribution of stress when stressed is even, and the load-carrying capacity of limiting stopper increases thereupon.

The specific embodiment
1. intermediate channel ledge terminations, 2. dumbbell, 3. limiting stopper, 4. locating dowel pin among the figure.
Shown in Fig. 1～8, slat conveyer is made of dumbbell 2, limiting stopper 3, circlip type locating dowel pin 4 three parts with the spacing component of dumb bells of screw-in; Dumbbell 2 two ends are provided with the flat structure with respect to dumbbell axis symmetry, and left-end flat structure front projection is a D shape symmetrical structure, and a rectangle positive stop lug boss is respectively arranged up and down in this termination; Right-hand member flat structure front projection is dolioform symmetrical structure, in this outside, termination an ellipse around boss is arranged, and boss is connected with a circular shaft with holes; Limiting stopper 3 is symmetry up and down, and there is a through hole that matches with dumbbell right-hand member circular shaft at the center, and there is an oval-shaped groove inboard; The through hole of limiting stopper 3 is through on the dumbbell circular shaft with holes, and oval-shaped groove matches with the ellipse around boss of dumbbell, and circlip type locating dowel pin 4 is packed in the hole of dumbbell right-hand member circular shaft.
During assembling, dumbbell 2 is had the groove that intermediate channel ledge termination 1 is put in the termination of two rectangle positive stop lug boss up and down, make the positive maintenance of dumbbell 2 length directions and ledge vertical, then dumbbell 2 is passed to the intermediate channel end along groove, when being pushed, dumbbell 2 moves to root of notch can not be mobile again the time, with two positive stop lug boss up and down is axle, and dumbbell 2 is turn 90 degrees to ledge termination 1 position-limited trough inward turning, makes dumbbell 2 positive concordant with the ledge front.The through hole of limiting stopper 3 is through on the dumbbell circular shaft with holes, oval-shaped groove is matched with the ellipse around boss of dumbbell, circlip type locating dowel pin 4 is packed in the hole of dumbbell 2 right-hand member circular shafts, buckle jump ring.
In the work, dumbbell 2 plays the effect that connects 1 of intermediate channel ledge termination, limiting stopper 3 restriction dumbbells 2 produce cross travel with respect to intermediate channel ledge termination 1, and circlip type locating dowel pin 4 plays restriction limiting stopper 3 and produces the effect that vertically moves with respect to intermediate channel ledge termination 1.
