Description

Technical Field

[0001] The invention relates to the technical field of railway maintenance machinery, and in particular to a mobile mechanism and a railway ballast excavation device. Background Art

[0002] The ballasted track of railways and urban rail transit is composed of rails, fasteners, sleepers, ballast beds and roadbeds from top to bottom. It is the main track structure form of current conventional railways and heavy-load railways, and also accounts for a certain proportion in special sections of high-speed railways and urban rail transit.

[0003] The track bed is composed of ballast, which is a granular structure. After forming the track bed, the functions are:

[0004] 1. The train load and track load are diffused through the ballast and then transferred to the roadbed, thereby reducing the load pressure on the roadbed surface and protecting the top surface of the roadbed;

[0005] 2. Provide longitudinal and transverse resistance for the rails, and maintain the geometric stability of the track;

[0006] 3. The elasticity and damping of the ballast can absorb the impact vibration between the wheel and rail;

[0007] 4. The loose nature of ballast makes it easy to break and deform, but also easy to operate, repair and adjust.

[0008] After long-term use, the railway line has become dirty, the ballast is broken, and the ballast loses its elasticity and drainage performance, which makes the entire ballast "hardened", which is not conducive to railway transportation. Therefore, when the degree of ballast uncleanliness exceeds 25% by weight, it must be screened to separate the dirt and clean ballast, and the ballast that meets the specifications is returned to the ballast along the return mechanism;

[0009] At present, the most commonly used method for cleaning and screening operations in the turnout area is to use an undercut device to cut into the bottom of the pillow from one side of the line, transport the dirty ballast at the bottom of the pillow to both sides of the line, and then use a slope ballast excavation device to transport the excavated dirty ballast to the screening and backfilling mechanism. The CQS300 turnout cleaning and screening machine currently used in China has an undercut device fixed on the excavation bucket wheel, which can only perform telescopic movements outward together with the bucket wheel and is driven by a hydraulic cylinder to perform rotation movements. The structure is complex and the undercut device cannot perform actions such as adjusting the collapse head and raising the head. The excavation efficiency is low and the operation is complicated. The undercut device produced by the foreign Plassay company is fixed to the frame through a rotating shaft, can be rotated, and can change its relative position with the slope excavation device according to actual operation needs, but cannot move longitudinally relative to the frame. It has a complex structure, is difficult to produce and manufacture, and has a complex process. Summary of the invention

[0010] The present invention provides a mobile mechanism and a railway ballast excavation device, which can be used for a ballast cleaning machine, and can arbitrarily adjust the relative position with the slope excavation device, can perform multi-degree-of-freedom movement relative to the vehicle body, and can execute the bottom cutting device to adjust the collapse and rise of the head. Through the excavation device and its mobile mechanism, the disadvantage that the bottom cutting device and the slope ballast excavation device are relatively fixed in position and cannot flexibly avoid obstacles is solved. At the same time, the disadvantage that the bottom cutting device cannot actively adjust the bottom cutting device to lift up or collapse is solved, and the operating state of the bottom cutting device at the bottom of the pillow can be better controlled.

[0011] The present invention provides a moving mechanism, comprising:

[0012] X-direction moving guide rail, X-direction moving frame, Z-direction moving mechanism, Y-direction moving mechanism, undercut device frame, X-direction rotating axis, and rotating axis around Y-direction;

[0013] The X-direction moving frame is suspended and installed on the X-direction moving guide rail, and the X-direction moving actuator and guide column are installed on the X-direction moving frame;

[0014] The Z-direction moving mechanism is provided with a Z-direction moving actuator, and rotary rollers are provided at both ends of the Z-direction moving mechanism, and the Z-direction moving mechanism is installed on the guide column through the rotary rollers;

[0015] The Y-direction moving mechanism comprises a Y-direction moving inner sleeve, a Y-direction moving outer sleeve, a rotary actuator and an undercut device suspension assembly, and the Y-direction moving mechanism is suspended on the Z-direction moving mechanism through the X-direction rotary shaft, and the Y-direction moving mechanism;

[0016] The undercut device frame includes an undercut device, an undercut device rotation drive assembly and an undercut device rotation execution assembly around the Y axis. The undercut device frame is suspended on the undercut device suspension assembly through the Y-axis rotation axis.

[0017] Preferably, a stopping device is installed on the X-direction moving frame, and the X-direction moving frame realizes reciprocating movement along the X-direction moving guide rail through the X-direction moving actuator.

[0018] Preferably, the X-direction moving actuator has an automatic locking function, and the X-direction moving frame can be positioned at any position of the X-direction moving guide rail through the locking function of the X-direction moving actuator and the stopping device on the X-direction moving frame.

[0019] Preferably, an angle is formed between the rotary roller and the guide column, and the Z-direction moving mechanism is positioned on the X-direction moving frame through the angle between the rotary roller and the guide column.

[0020] Preferably, the Z-direction moving mechanism moves on the X-direction moving frame via the rotary roller.

[0021] Preferably, the rotary actuator is used to drive the Y-direction moving mechanism to perform a rotary motion.

[0022] Preferably, the rotary drive assembly of the undercut device includes a rotary drive actuator, a rotary drive chain, a rotary transmission assembly and a rotary support body.

[0023] Preferably, the undercutting device is rotated about the Y-axis by an actuator to drive the undercutting device frame to rotate.

[0024] Preferably, the rotation of the Y-axis moving mechanism is used to drive the lifting and collapsing actions of the undercutting device, and the rotation of the undercutting device frame is used to drive the undercutting device to perform the lifting and collapsing actions.

[0025] A railway ballast excavation device comprises the above-mentioned moving mechanism.

[0026] Compared with the prior art, the advantages of the present invention are:

[0027] 1. The undercut excavation device is suspended separately on the vehicle body, and its relative position is not related to the slope ballast excavation device, so it has the ability to move independently.

[0028] 2. By setting up an X-direction moving mechanism, a Z-direction moving mechanism and a Y-direction moving mechanism, the undercutting device can be controlled at any position.

[0029] 3. Through the cooperation of the rotary shaft and the rotary actuator, the state of the undercut device during excavation operation at the bottom of the pillow can be adjusted, and the lifting or collapsing of the undercut device can be controlled. BRIEF DESCRIPTION OF THE DRAWINGS
