Abstract
There is a groove at the middle part of the scraper component of double-chain conveyer, and groove is done in echelon, and the center line with transfer machine is vertical along its length with 6 for its two thrustwall 5.There is a boss 7 at the crossbeam middle part, and its shape is the same with groove 3.When with screw 8 scraper plate 1 and crossbeam 2 being tightened together, boss 7 just embeds in the groove 3, and is close to groove walls 5 and 6, has so just stoped the end float misalignment of crossbeam effectively.
Description
Theme of the present invention is the scraper component of double-chain mining conveyer, is used for the transportation of mineral products.
By having known scraper component on No. 127024 patents of Poland, the chain link Position Design of its messenger chain stress part is reasonable, the spacing of the chain link line of centers that particularly is parallel to each other is decided to be four times to five times of chain link ring body diameter, purpose for firm crossbeam and increase scraper plate intensity, in its both sides, just provide and be subjected to force compensating connecting part with above-mentioned crossbeam with screw.The design of this blade member provides best stressed distribution, and has reduced the damage rate of scraper-type conveyer.Transmit a large amount of coals so that the scraping plates system of motion is subjected to huge axial dynamic force in the conveyer delivery chute, can make crossbeam and tightening screw impaired, cause crossbeam flexural deformation or break, screw damages or the screw thread ease is buckled.
The objective of the invention is further to improve the design of scraper component, eliminate by crossbeam and break and fastening its screw damages and the conveyer fault that causes.
Above-mentioned purpose is to use by the improvement design of theme of the present invention to realize.
Main points of the present invention are: in the middle beam joint place of scraper plate a groove is arranged, this groove is preferably trapezoidal, and its two relative thrustwall are perpendicular to the axis of conveyer.On the other hand, there is one with the identical boss of above-mentioned groove shapes at the crossbeam middle part, after tightening together with screw, groove and projection section are overlapping, thus, the front and rear wall of above-mentioned groove has formed the rectangular thrust flanges of axis crosscut with conveyer, has so just prevented moving axially of crossbeam, and has alleviated the dynamic load on the above-mentioned screw.In view of this, owing on scraper plate and crossbeam, used groove and the boss that firm thrust function is arranged, on the one hand, the flexural deformation of recurrent crossbeam and fracture so far and the deletrious dynamic force that acts on the crossbeam tightening screw have been eliminated really, on the other hand, full maintenance crossbeam and scraper plate, and, damage by crossbeam and above-mentioned screw that the fault that causes need not spend any material and money just can be eliminated.The advantage and the benefit of present this essence of an invention that Here it is.
An embodiment of theme of the present invention has represented the lateral plan of scraper component as shown in Figure 1, and Fig. 2 is the birds-eye view of scraper component, the cutaway view of the A-A line that Fig. 3 is a scraper component in Fig. 1.According to the present invention, there is a groove 3 in the place of the middle part of scraper plate 1 crossbeam 2 applyings just, preferably polygon as shown in Figure 3 such as trapezoidal shape.Two relative thrustwall of above-mentioned groove 3 are along the center line 4 of its length direction perpendicular to conveyer.On the other hand, at the middle part of crossbeam 2 boss 7 is arranged, it is the same with the shape of groove 3.When with screw 8 crossbeam 2 being tightened together with scraper plate 1, boss 7 just embeds in the groove 3, is close on the wall 5 and wall 6 with the vertical groove of the center line of conveyer.Like this, the front and rear wall 5 and 6 of above-mentioned groove 3 has just formed the thrust flanges perpendicular to conveyer center line 4.They prevent moving axially of crossbeam 2 effectively, and have alleviated the dynamical load of screw 8, and this load can damage screw and cause that whole scraper component damages, and can damage conveyer when the most serious.
Claims (1)
- A double-chain conveyer has the central guiding mechanism of chain pull parts, the horizontal chain link of its stress part is fastened on the crossbeam, forming two at its restraint location parallels to the axis, at its screwed joint place stressed compensating action is arranged with crossbeam, the feature of the scraper component of this double-chain conveyer is: in the middle, just one groove 3 is arranged with crossbeam 2 joint places, groove 3 is preferably made trapezoidal, two relative thrustwall 5 and 6 are along its length perpendicular to the center line 4 of conveyer, there is a boss 7 at the middle part of crossbeam 2, shape unanimity with groove 3, when crossbeam 2 usefulness screws 8 are fastened on the scraper plate 1, boss 7 and groove 3 partially overlap, and like this, the front and rear wall 5 and 6 of above-mentioned groove has formed the thrust flanges perpendicular to conveyer center line 4.
