Description

Technical Field

[0001] The present invention relates to the technical field of railway equipment, and more particularly to a ballast cleaning device. In addition, the present invention also relates to a cleaning method of the ballast cleaning device. Background Art

[0002] Ballast typically refers to the stone material laid on the road surface beneath railway sleepers. It supports and secures the sleepers, distributing the pressure exerted on them to the ground, reducing the degree and rate of road deformation and mitigating the impact between vehicles and rails. After prolonged use, sleepers can fail, such as falling pieces and breaking, and must be promptly replaced to ensure railway safety. During sleeper replacement, after removing the failed sleeper, the ballast must be cleaned and leveled to prepare for the placement of a new sleeper.

[0003] In related technologies, sleeper replacement ballast handling devices can be divided into two types according to their working mode: the cutting type and the suction type. The cutting type ballast handling device mainly cuts off the rails at the entry and exit points of the sleeper replacement operation, removes the old sleepers, and then flattens the ballast by cutting, and then lays new sleepers. After the sleeper replacement is completed, the ballast filling operation is carried out. The suction type ballast handling device mainly lifts the rails to a certain height during the running process and uses wind power to suck and recover the ballast. When the conditions for laying new sleepers are met, new sleepers are laid. After the sleeper replacement is completed, other working devices complete the ballast filling.

[0004] Among them, the cutting-type ballast processing device for sleeper replacement requires cutting the rails, which has a complicated process and low work efficiency, and cannot meet the requirements of continuous sleeper replacement operations; the ballast suction-type ballast processing device for sleeper replacement uses wind power to suck and recover ballast, which has low efficiency and also cannot meet the requirements of continuous sleeper replacement operations.

[0005] In summary, how to improve the working efficiency of the ballast processing device to meet the operational requirements of continuous sleeper replacement is an urgent problem to be solved by those skilled in the art. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0061] The core of the present invention is to provide a ballast cleaning device that can perform efficient ballast cleaning operations, meet the operational requirements of continuous sleeper replacement, improve the automation level and efficiency of the cleaning operation, and enhance operational safety. Another core of the present invention is to provide a cleaning method for the above-mentioned ballast cleaning device.

[0062] The ballast cleaning device provided by the present invention includes a frame 1, a running mechanism 2, a cleaning mechanism, a rail lifting mechanism 4, and a control mechanism. Figure 1 、 Figure 2 .

[0063] The running mechanism 2 is supported on the bottom of the frame 1 and moves the entire cleaning device in the length direction of the track 9 by driving the frame 1 to move.

[0064] Please refer to Figure 1 As a preferred embodiment, two sets of running mechanisms 2 are symmetrically arranged on both sides of the bottom of the frame 1, supporting the frame 1 and moving along the length direction of the track 9. The length direction here refers to Figure 1 The left and right directions in the figure do not limit the length of the track 9.

[0065] The cleaning mechanism includes a slope cleaning mechanism 3 and a sleeper area cleaning mechanism arranged in sequence along the walking direction of the running mechanism 2, wherein the walking direction of the running mechanism 2 is Figure 1 Direction indicated by the arrow.

[0066] The slope cleaning mechanism 3 is movably arranged on the frame 1 and is used to clean the slope ballast 11 on both sides of the track 9. The slope cleaning mechanism 3 can move freely, such as lifting, rotating, and traversing, to meet the operation requirements of different track sections 9.

[0069] Optionally, the slope cleaning mechanism 3 may be a push-type cleaning member, or a planing-type or digging-type cleaning member, whichever is more efficient and high-quality in cleaning the slope ballast 11 .

[0070] The sleeper area cleaning mechanism is connected to the frame 1 and can move through the bottom of the sleeper 10 to clean and transfer the ballast at the bottom of the sleeper 10.

The traction sliding sleeve 42 and traction rod 45 respectively provide the traction force for the forward movement of the rail lifting mechanism 4 and the lateral shifting force, thereby ensuring the rigidity of the mechanism and improving the stability and safety of operation. In one embodiment, the traction sliding sleeve 42, traction rod 45 and the vehicle frame 1 form a quadrilateral structure to ensure the strength of the connection and improve the safety of the operation of the rail lifting mechanism 4.

[0078] The first clamp 43 and the second clamp 44 clamp the rail 9 when working, and the rail lifting function is realized by the rail lifting cylinder 47; the rail lifting and transverse movement cylinder 46 drives the sliding sleeve bracket 41 to move transversely to realize the function of moving the rail.

[0079] The control mechanism is arranged on the frame 1 and is the control unit of the entire cleaning device. The running mechanism 2, cleaning mechanism and rail lifting mechanism 4 are all connected to the control mechanism signal, and the start, stop, lifting and rotation operations of the above three are realized through the control mechanism.
