Description

Technical Field

[0001] The present application relates to the technical field of railway maintenance equipment, and in particular to a ballast sweeping attachment and an excavator. Background Art

[0002] Ballast is the small stone laid beneath the railroad tracks. When a train passes, the ballast on the trackbed rubs against each other, causing it to compress and expand, evenly distributing the immense pressure and ensuring smooth train operation. However, due to long-term use, the ballast is easily crushed into powder. Furthermore, the intrusion of dirt, coal ash, and other contaminants causes the contaminated soil to compact, undermining the stability of the trackbed structure. This requires excavation, removal of the contaminated ballast, and backfilling.

[0003] like Figure 1 As shown, ballast after backfill, ballasting, or shaping can easily get stuck in fasteners, compromising safe train operation. Ballast must be cleaned between rails, outside the rails, and especially in the gaps between fasteners. Traditionally, ballast sweeping is done manually. Now, there are independently powered ballast sweepers, but these are large and heavy. They require specific operating times, requiring the sweeper to be lifted onto the track and then removed after the job is complete, making it difficult to quickly move the machine up and down the track.

[0004] Therefore, it is necessary to provide a ballast sweeping attachment that is convenient, flexible, and easy to use on and off the road. Utility Model Content

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings. Example 1

[0032] This embodiment provides a ballast sweeping attachment, which is connected to an excavator via a quick-change device and is used for cleaning and tidying railway ballast.

[0033] Reference Figure 2 The ballast sweeping attachment is provided with an integral frame 2, and a connecting end 1 is fixedly provided at the upper end of the frame 2. The connecting end 1 is used to connect to the quick-changing device of the excavator, thereby driving the movement of the ballast sweeping attachment through the movement of the excavator's boom. When the connecting end 1 is connected to the quick-changing device of the excavator, the excavator moves along the extension direction of the track, and the lower end of the frame 2 moves close to the rail. A handwheel 5 is connected to the position of the rail on one side of the frame 2, and the handwheel 5 is connected to a fastener cleaning device 3. The function of the fastener cleaning device 3 is to clean the ballast of the fastener. A protective cover 4 is provided on the outside of the frame to shield the internal components.

[0034] Due to different railway lines, the height of the fastener relative to the rails is different. The fastener cleaning assembly needs to be adjusted to a specific height. Or if the hose of the fastener cleaning assembly is worn and the hose becomes shorter, the fastener cleaning assembly also needs to be adjusted downward. Figure 3 and Figure 4To properly position the hose of the fastener cleaning device, the fastener cleaning device is designed to be adjustable up and down. A screw 51 is fixedly connected to the handwheel 5. A nut 35, threadedly connected to the screw 51, is fixedly mounted within the fastener body mounting bracket 34 of the fastener cleaning device 3. To adjust the fastener cleaning height, the handle is rotated, causing the screw 51 to rotate. Because the edge of the frame 2 abuts the square fastener body mounting bracket 34 and the screw 51 is threadedly connected to the nut 35, the rotation of the screw 51 causes the fastener body mounting bracket 34 to drive the entire fastener cleaning device 3 up and down vertically.

[0035] A button body motor 31 is fixed on the button body mounting frame 34, and the output end of the button body motor 31 is fixedly connected to the flange seat 32. The flange seat 32 is provided with six button body hoses 33 along the circumferential array. Each button body hose 33 is in the shape of a long strip, one end of which is connected to the flange seat 32 and the other end is in contact with the ballast.

[0036] There are four groups of fastener cleaning devices 3, one group is provided at the corresponding positions inside and outside of a track.

[0037] See also Figure 3 and Figure 5 A shaft-driven motor 6 is fixed to the upper portion of the frame 2. Two shaft-driven motors 6 are installed: one motor controls the inside and outside cleaning of one rail, and the other motor controls the inside and outside cleaning of the other rail. One shaft-driven motor 6 drives a first spindle 71 via a chain, while the other shaft-driven motor 6 also drives a second spindle 72 via a chain. Both ends of the first and second spindles 71 and 72 are connected to bearing blocks 73.

[0038] In other embodiments, the shaft-driven motor 6 and its transmission mechanism may also be replaced with a hydraulic system transmission.

[0039] The first main shaft 71 is used to clean the inside and outside of a rail. An inner cleaning device 74 is provided at a corresponding position between two rails for cleaning, and an outer cleaning device 75 is provided at a corresponding position for cleaning the outer side of the rails.

[0040] The second main shaft 72 cleans the inner and outer areas of the other rail. An inner sweeping device 74 is provided at a corresponding position for cleaning between the two rails, and an outer sweeping device 75 is provided at a corresponding position for cleaning the outer sides of the rails.

[0041] See also Figure 6The internal sweeping device 74 is coaxially provided with a first sweeping group 741, a second sweeping group 742 and a third sweeping group 743, and each sweeping group is provided with three groups of hose fixing seats 76 in a circumferentially fixed array. The hose fixing seat 76 extends along the axial direction of the first main shaft 71. The circumferential position of the hose fixing seat 76 of each sweeping group is different on the first main shaft. There are nine hose fixing seats 76 in total in the three sweeping groups, which evenly divide the 360° circumferential angle of the first main shaft 71, that is, the circumferential angle between two adjacent hose fixing seats 76 is 40°. The hose fixing seat 76 is provided with a main sweeping hose 79, and the angle between the extension directions of two adjacent main sweeping hoses 79 in the circumferential direction is 40°, which makes it easier to separate the ballast outward. Four main sweeping hoses 79 are provided on each hose fixing seat 76 of the internal sweeping device 74.

[0042] The external sweeping device 75 is also provided with three cleaning groups, each cleaning group is provided with three groups of hose fixing seats 76 , and each hose fixing seat 76 of the external sweeping device 75 is provided with two main sweeping hoses 79 .

[0043] Reference Figure 5 Similarly, the internal sweeping device 74 on the second main shaft 72 is also provided with three cleaning groups, each cleaning group is provided with three hose fixing seats 76, and each hose fixing seat 76 is provided with four main sweeping hoses 79; the external sweeping device 75 of the second main shaft 72 is also provided with three cleaning groups, each cleaning group is provided with three hose fixing seats 76, and each hose fixing seat 76 of the external sweeping device 75 is provided with two main sweeping hoses 79.

[0044] When sweeping ballast, the hose contacts the ballast and wears out quickly. In order to facilitate the replacement of the main sweeping hose 79 with greater wear, refer to Figure 7 The hose holder 76 comprises two inverted L-shaped strips, each with internally threaded holes at both ends. A stopper bolt 77 screws into the internally threaded hole at one end, securing the main sweep hose 79 within the hose holder 76. The main sweep hose 79 is then secured within a sliding seat 78. The lower end of the sliding seat 78 features a protrusion that matches the size of the hose holder 76. Once the sliding seat 78 is installed within the hose holder 76, another stopper bolt 77 is screwed into another set of internally threaded holes at the other end of the hose holder 76, completing the installation of the main sweep hose 79. By screwing the stopper bolt 77 in and out, the sliding seat 78 can be easily installed, removed, and replaced. Example 2
