Description

Technical Field

[0001] The utility model relates to a ballast scraping device for a railway screening machine, belonging to the technical field of engineering machinery excavators. Background Art

[0002] The screen cleaning machine is an excavator attachment used to clean up the debris under the rails on the railway. The screen cleaning machine transfers the debris from under the sleepers to the rear of the screen cleaning machine through its stripping chain and ballast stripping device to facilitate the maintenance of the railway. The traditional ballast stripping device of the screen cleaning machine adopts a bucket tooth structure, which uses the bucket teeth to rotate and move the debris to achieve the transfer of the debris. The bucket tooth ballast stripping structure has a small amount of ballast stripping, wears quickly, has a short service life, and is difficult to replace the bucket teeth.

[0003] like Figure 1 As shown, the prior art ballast removal device includes a shaft seat 1, a ballast removal plate 2, a tooth seat 3, a bucket tooth 4, and a pin assembly 5. The ballast removal device is a device in which three tooth seats 3 are welded in parallel on the ballast removal plate 2, and the bucket teeth 4 are fixed by the pin assembly 5 in a transverse pin fixing manner. When working, the ballast removal device is driven to rotate by a motor, and the rotating bucket teeth 4 are used to contact the crushed slag to move the crushed slag.

[0004] However, Figure 1 The ballast removal device provided has the following disadvantages:

[0005] (1) The front end of the traditional ballast removal device is composed of three parallel bucket teeth. During use, the bucket teeth close to the inner side wear faster and the replacement cycle is shorter than that of the other two bucket teeth. When replacing the inner bucket teeth, because the bucket teeth are fixed by transverse pins and the bucket teeth are small in distance, the other two bucket teeth need to be removed at the same time before the inner bucket teeth can be replaced. In addition, the number of bucket teeth is large, which makes it difficult to replace the bucket teeth and the replacement time is long, increasing the time cost.

[0006] (2) The gap between the bucket teeth is large, resulting in a small ballast removal capacity, and the crushed slag leaks out of the gap, resulting in low ballast removal efficiency. Summary of the invention

[0007] In view of the problems existing in the prior art, the utility model provides a novel ballast removing device.

[0008] The utility model is implemented according to the following technical solutions:

[0009] In a first aspect, the utility model discloses a ballast removing device, comprising:

[0013] In some embodiments, the blade plate is a front-to-back symmetrical structure, and the middle part of the blade plate is connected to the ballast remover plate through a detachable part; after the end of the blade plate located on the outside of the ballast remover plate is worn, the front and rear ends of the blade plate are replaced, and the unworn end of the ballast remover plate is used to move the crushed stone.

[0014] In some embodiments, a plurality of symmetrically arranged through holes I are provided in the middle of the blade plate, and a through hole II corresponding to through hole I is provided at the front end of the ballast plate. When the blade plate is assembled front and back interchangeably, through holes I can be aligned one by one with through holes II.

[0015] In some embodiments, the through hole I is a countersunk square neck bolt hole, and the detachable component includes a countersunk square neck bolt and a locking nut; the countersunk square neck bolt passes through the countersunk square neck bolt hole and the through hole II and is tightened by the locking nut, and the square body part of the countersunk square neck bolt cooperates with the square hole of the countersunk square neck bolt hole to realize the bolt anti-rotation effect.

[0016] In some embodiments, four through holes I are provided in the middle of the blade plate. The four through holes I are symmetrical about the left and right midlines of the blade plate on the one hand, and symmetrical about the upper and lower midlines of the blade on the other hand.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] like Figure 2 As shown, the ballast removing device includes a shaft seat 1, a plurality of ballast removing plates 2 and a plurality of blade plates 6, 7; the plurality of ballast removing plates 2 are evenly and alternately arranged on the outer circumferential surface of the shaft seat 1, and are in a radial structure with the central axis of the shaft seat 1; the plurality of blade plates 6, 7 are detachably mounted on each ballast removing plate 2, and a part of the installed blade plates 6, 7 is in contact with the ballast removing plate 2, and the other part extends from the front end of the ballast removing plate 2, and the extended part is used to move the crushed stone to realize the transfer of the crushed stone.

[0040] Continue to refer to Figure 2 As shown, the ballast removal plate 2 is welded to the outside of the shaft seat 1 in six equal parts by welding, and bolt holes connected to the blade plates 6 and 7 are provided on the ballast removal plate 2.

[0041] The blade plate is further described below:

[0042] like Figure 3 , Figure 5 As shown, the blade plates 6 and 7 are of front-to-back symmetrical structure, made of high-strength wear-resistant steel plates, and a symmetrically arranged chamfered groove is provided at both ends of the ballast stone contact surface; the middle part of the blade plates 6 and 7 is connected to the ballast plate 2 through a detachable part; after the end of the blade plates 6 and 7 located on the outside of the ballast plate 2 is worn, the front and rear ends of the blade plates 6 and 7 on the ballast plate 2 are replaced, and the unworn end of the ballast plate 2 is used to move the crushed slag.

[0043] Continue to refer to Figure 3 , Figure 5 As shown, four through holes I are provided in the middle of the blade plates 6 and 7. On the one hand, the four through holes I are symmetrical with the left and right center lines of the blade plates 6 and 7, and on the other hand, they are symmetrical with the upper and lower center lines of the blades 6 and 7. This arrangement can be interchanged front and back during assembly; through holes II are provided at the front end of the ballast plate 2, which correspond one to one with the through holes I. When the blade plates 6 and 7 are interchanged front and back, the through holes I can be aligned one by one with the through holes II.

[0044] like Figure 3 , Figure 4 , Figure 5 As shown, through hole I is a countersunk square neck bolt hole, and the detachable parts include a countersunk square neck bolt 8, a locking washer 9 and a locking nut 10; the countersunk square neck bolt 8 passes through the countersunk square neck bolt hole and the through hole II, and then the locking washer 9 is installed, and finally it is tightened by the locking nut 10, and the square body part of the countersunk square neck bolt 8 cooperates with the square hole 11 of the countersunk square neck bolt hole to realize the bolt rotation prevention effect.

[0045] like Figure 2 , Figure 3 As shown, two blade plates 6 and 7 are installed side by side on a ballast scraper plate 2. The blade plate 7 near the inner side wears faster than the blade plate 6 near the outer side. The inner and outer blade plates are swapped and assembled to achieve multiple uses. Secondly, the gap between the blade plates 6 and 7 is very small, which can increase the capacity of the ballast scraper 2 and improve work efficiency.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, when the ballast removal device is working, the motor drives the rotation to move the crushed slag backwards, mainly through the blade plates 6 and 7 contacting the crushed slag, which causes the blade plates 6 and 7 to wear; and the blade plate 7 close to the inside wears faster than the blade plate 6 on the outside. Figure 5 The blade plate structure shown in the figure, when the front end 7-1 of the blade plate 7 is worn too short, the rear end 7-2 of the blade plate 7 can be swapped front to back and continued to be used. If both the front and rear ends of the blade plate 7 are worn, the blade plate 6 and the blade plate 7 can be swapped and assembled to achieve multiple uses and reduce material costs; secondly, the gap between the blade plates 6 and 7 is very small, which can increase the ballast removal capacity and improve work efficiency; finally, because the blade plates 6, 7 and the ballast removal plate 2 are locked with countersunk square neck bolts 8, locking washers 9 and locking nuts 10, loosening of the bolts caused by rotation of the ballast removal device can be avoided, and the problem of inconvenient disassembly of the bucket teeth in the prior art is solved. In addition, because the countersunk square neck bolts 8 are used for connection, the structure is relatively special, and square holes 11 need to be opened in the blade plates 6 and 7 to limit the bolts; even when the top of the countersunk square neck bolt 8 and the blade plates 6 and 7 are worn together, it will not affect the assembly and disassembly of the bolts.

[0047] The utility model also discloses a railway cleaning machine, which is equipped with the above-mentioned ballast-scraping device. When the ballast-scraping device works for a period of time, the blade plate will be worn and needs to be replaced. When replacing, there is no need to replace a new blade plate, and only the front and rear of the blade plate need to be swapped and installed, which reduces the cost; in addition, the blade plate and the ballast-scraping plate are connected by bolts, which is convenient for disassembly, can reduce the replacement time of the blade plate, and improve work efficiency.

[0048] The utility model also discloses a working device, which is equipped with the above-mentioned railway screening machine.

[0049] The utility model also discloses an engineering machine which is equipped with the working device mentioned above.
