Description

Technical Field

[0001] The invention relates to the technical field of railway track bed ballast cleaning, in particular to a slope cleaning vehicle with an electrically controlled digging chain. Background Art

[0002] The railway track bed is an important component to ensure the safe operation of the railway. The track bed refers to the ballast cushion layer laid on the roadbed surface under the railway sleepers. Its main function is to support the sleepers, absorb the impact and vibration of locomotives and vehicles, and evenly transfer the pressure on the sleepers to the roadbed surface. At the same time, it fixes the position of the sleepers, prevents the sleepers from moving vertically and horizontally, and reduces the deformation of the roadbed.

[0003] The long-term operation of trains has repeatedly impacted the line. Over time, the ballast is broken and the roadbed is dirty, which causes the roadbed to gradually lose its elasticity and drainage performance, and the roadbed is prone to "hardening" and mud. Therefore, it is necessary to regularly break and clean the roadbed to screen out the dirt at the bottom of the roadbed, improve the drainage performance of the roadbed, restore the elasticity of the roadbed, and ensure a more stable line.

[0004] At present, the ballast of the track bed is mainly operated by the digging chain, and the installation mechanism of the traditional digging chain is mostly fixed directly on both sides of the cleaning vehicle. Not only is the adaptation range limited, but the thickness of the cleaning is also very fixed, resulting in low operability. At the same time, it is impossible to link the rapid pre-cleaning after excavation, which makes the subsequent operation complicated and the cleaning efficiency is low. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the mounting mechanisms of traditional excavating chains are mostly directly fixed on both sides of the screening vehicle, which not only has a limited adaptation range, but also has a very fixed thickness for the screening, resulting in low operability. At the same time, after excavation, rapid pre-screening cannot be linked, resulting in complicated subsequent operations and low screening efficiency.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a slope screening vehicle with an electrically-controlled digging chain, comprising electrically-controlled lifting plates installed on both sides of a main frame, a lateral screening frame installed at the lower end of the electrically-controlled lifting plates, an electrically-controlled flipping digging chain movably mounted on one side of the lateral screening frame, an electrically-controlled bottom material guide plate movably mounted at the lower end of the lateral screening frame, an electrically-controlled linkage slag guide pipe mounted at the outer end of the electrically-controlled bottom material guide plate, a detachable metal screening frame fixedly mounted on the inner bottom surface of the lateral screening frame, and a side-mounted inner material shifting mechanism fixedly mounted on the outer surface of the lateral screening frame.

[0007] The electric-controlled lifting platform comprises electric-controlled lifts fixed on both sides of the main frame and a side lifting platform of an L-shaped structure installed at the protruding end of the bottom of the electric-controlled lift.

[0008] The upper end of the lateral cleaning frame and the upper surface of the lateral lifting plate are fixedly assembled with the lateral lifting plate, and the lateral cleaning frame is provided with a lateral turning opening matching the electrically controlled turning type digging chain toward the main frame surface.

[0009] The electrically controlled flipping digging chain comprises a flipping adjustment frame with a movable shaft connected to the inside of a lateral cleaning frame, an electrically controlled adjustment support rod, a digging chain movably sleeved on the outside of the flipping adjustment frame, rake teeth installed on the outside of the digging chain, and a sprocket installed inside the flipping adjustment frame.

[0010] Both sides of the lower surface of the lateral cleaning frame are provided with bottom side mounting frames for mounting an electrically controlled bottom material guide plate.

[0011] The electrically controlled bottom material guide plate comprises a bottom flip material guide plate movably connected to a bottom mounting frame via an axis and a bottom adjusting support rod for controlling the bottom flip material guide plate.

[0012] A plurality of circular mounting openings are provided on the outer side surface of the lateral cleaning frame, and an annular sinking groove is provided at the inner opening of the circular mounting opening.

[0013] The side-mounted inner material removing mechanism includes a lateral transmission cover shell installed on the outer side of the lateral cleaning frame, a lateral adjustment disk movably installed inside the circular installation opening, a lateral material removing rod fixed on the inner side wall of the lateral adjustment disk, an external belt transmission wheel axially fixed on the outer side wall of the lateral adjustment disk, a lateral drive motor and a lateral transmission belt fixed on the outer side of the lateral cleaning frame.

[0014] The bottom flip material guide plate is of expandable structural design, and the bottom flip material guide plate includes a flip adjustment plate movably connected to the bottom mounting frame through an axis, a bottom guide frame fixedly installed at the lower ends of both sides of the flip adjustment plate, a bottom extension plate slidably inserted in the bottom guide frame, and a side-mounted electric-controlled screw rod installed in the bottom guide frame. The electric-controlled linkage slag guide pipe is fixedly installed on the outside of the bottom extension plate.

[0015] An electrically controlled tail material guide pipe is movably mounted at the rear discharge port of the lateral cleaning frame.

[0016] The beneficial effects of the present invention are: (1) The slope cleaning vehicle with an electric-controlled digging chain of the present invention adopts an electric-controlled lifting mechanism design, which can control the height of the electric-controlled flip digging chain, so that it can be freely adjusted according to the digging depth of the ballast cushion layer, greatly improving the thickness of the cleaning, not only improving the applicability, but also facilitating storage; (2) An electrically controlled bottom guide plate is movably mounted at the lower end of the lateral cleaning frame. Together with the detachable metal screening frame on the inner bottom of the lateral cleaning frame, the cleaned ballast can be pre-processed to quickly remove some fine and fluid impurities to the outside, thereby reducing the difficulty of subsequent processes and improving cleaning efficiency. (3) The electrically controlled bottom guide plate with an extended structure design can increase the range of material guides, making the application scenarios more convenient; (4) A side-mounted inner material-discharging mechanism is fixedly installed on the outer side of the lateral cleaning frame, which can improve the internal material guiding efficiency and the cleaning efficiency; (5) The use of a detachable metal screen frame can facilitate subsequent maintenance and reduce applicable costs; (6) The side-mounted inner feeding mechanism adopts a side-mounted structural design, which can not only be driven synchronously, but also is easy to install and maintain; (7) The electrically controlled flipping excavation chain can quickly guide the ballast into the lateral cleaning frame, improving the lateral material guiding efficiency; (8) By installing an electrically controlled linkage slag guide pipe on the outside of the electrically controlled bottom guide plate, the removed materials can be easily and quickly guided away, reducing the difficulty of subsequent processing.

[0025] Working principle: the main frame moves along the rails, and then the electrically-controlled lifting plate 1 drives the lateral screening frame 2 to descend, and then controls the electrically-controlled flipping digging chain 3 to descend under the rails, and then the electrically-controlled flipping digging chain 3 flips under the rails, and uses the electrically-controlled flipping digging chain 3 to lower the ballast under the rails to peel it outward, and then screen the impurities through the lateral screening frame 2, and then introduce them outward from the electrically-controlled bottom guide plate 4 to the electrically-controlled linkage slag guide pipe 5, and use the air pump at the front end of the electrically-controlled linkage slag guide pipe 5 to quickly blow away the internal impurities, and then use the set guide pipe on the rear side of the electrically-controlled linkage slag guide pipe 5 to quickly blow to the waste slag collection mechanism on the rear side.

[0026] In order to cooperate with the lateral electric lifting adjustment, the electric lifting platform 1 includes an electric lift 01 fixed on both sides of the main frame and an L-shaped lateral lifting platform 02 installed at the bottom protruding end of the electric lift 01.

[0027] The electric lift 01 controls the lateral lift plate 02 to adjust the lifting and lowering by telescoping.

[0028] In order to cooperate with installation and lateral adjustment, the upper end of the lateral cleaning frame 2 is fixedly assembled with the upper surface of the lateral lifting plate 01 and the lateral lifting plate 01, and a lateral flipping opening matching the electrically controlled flipping digging chain 3 is opened on the lateral cleaning frame 2 toward the main frame surface.

[0032] The bottom adjustment support rod 42 controls the bottom flip guide plate 41 to flip and adjust by telescoping, so that the lower end opening of the detachable metal screening frame 6 is controlled to open and close, which facilitates the introduction of impurities inside the side cleaning frame 2 from the opening to the bottom flip guide plate 41, and then uses the bottom flip guide plate 41 to introduce them outward into the electric-controlled linkage slag guide pipe 5 to complete the purpose of preliminary screening.

[0033] In order to cooperate with the lateral movable assembly limit, a plurality of circular installation openings are provided on the outer side surface of the lateral screening frame 2, and the inner openings of the circular installation openings are provided with an annular sinking groove.

[0035] The lateral drive motor 75 drives the lateral drive belt 76 to move through the active pulley on the output shaft, and drives the external belt drive wheel 74 at the same time, thereby driving the lateral adjustment disks 72 at all positions to rotate, and then synchronously drives the lateral material shifting rod 73 to shift inside the lateral screening frame 2. The bottom and upper ballast can be swapped by shifting, which not only improves the separation effect, but also facilitates the movement of the ballast inside the lateral screening frame 2.
