Description

Technical Field

[0001] The invention relates to the technical field of excavation devices, and in particular to a railway side slope ballast excavation device. Background Art

[0002] The ballasted track of railways and urban rail transit consists 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-duty railways, and also has a certain proportion in special sections of high-speed railways and urban rail transit. Among them, the ballast bed is composed of ballast, which is divided into the slope area and the center area. Because the ballast is a granular structure, the functions formed after the ballast bed is formed are:

[0003] (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;

[0004] (2) Providing longitudinal and lateral resistance to the rails, thus maintaining the stability of the track geometry;

[0005] (3) The elasticity and damping of the ballast can absorb the impact vibration between the wheel and rail;

[0006] (4) The loose nature of ballast makes it easy to break and deform, but also easy to work with, repair and adjust.

[0007] After long-term use, the drainage performance of the slope area of ​​the railway line has declined due to dirtiness, which has a serious impact on the line quality and driving safety. To solve this problem, it is a common practice in the industry to perform screening operations on the slope area. Slope screening operations can effectively restore the drainage performance of the ballast bed and help improve the line quality. With the side cutter plate excavation device at the bottom of the pillow, the slope excavation device can also be used as a ballast loading device;

[0008] At present, the slope cleaning and screening devices widely used in China are waterwheel-type single-chain slope excavating devices and bucket-wheel-type excavating devices. The waterwheel-type single-chain slope excavating device is composed of a guide trough body, a driving device, an excavating chain, a tensioning mechanism, a supporting device, etc. During operation, the excavating chain is driven by a power source to rotate at high speed in the guide trough body to excavate the ballast of the slope. This method can effectively excavate the ballast of the slope, but when used in conjunction with a pillow bottom side-cutting blade excavating device, it has the disadvantage of low ballast loading efficiency; the bucket-wheel-type excavating device has a complex bucket wheel structure, poor motion adjustment ability, slow rotation, no ballast gathering plate, and low ballast loading efficiency. Summary of the invention

[0009] The invention provides a railway side slope ballast excavation device, which is used for efficient excavation of side slope ballast and can better cooperate with a side-cutting pillow bottom excavation blade to transport away the ballast excavated by the pillow bottom blade.

[0010] The present invention provides a railway side slope ballast excavation device, comprising:

[0011] Power unit, ballast unit, support unit;

[0014] The supporting unit includes a supporting shaft and a supporting seat.

[0015] Preferably, the pillow bottom ballast digging chain and the side slope ballast digging chain are arranged side by side, and the pillow bottom ballast digging chain and the side slope ballast digging chain are arranged side by side at the ballast digging position, the pillow bottom ballast digging chain is responsible for conveying the ballast dug out by the pillow bottom side-cutting ballast digging knife, and the side slope ballast digging chain is responsible for autonomously digging and conveying the ballast on the side slope;

[0016] The pillow bottom ballast excavation chain and the side slope ballast excavation chain are not completely separated. When the pillow bottom ballast excavation chain or the side slope ballast excavation chain excavates more ballast, part of the ballast can be allocated to the excavation track of the other excavation chain, so that both excavation chains can excavate efficiently.

[0017] The sliding guide grooves of the excavating chains for cyclically rotating the pillow bottom ballast excavating chain and the side slope ballast excavating chain are supported by an integral rigid frame formed by connecting a group of connecting pieces, and the sliding guide grooves provide a stable rotation track for the excavating chains.

[0018] Preferably, the pillow bottom ballast digging chain and the side ramp ballast digging chain are provided with digging chain driving assemblies away from the ballast feeding area, and the digging chain driving assemblies are used to drive the pillow bottom ballast digging chain and the side ramp ballast digging chain to cyclically move.

[0019] Preferably, the ballast gathering plate is arranged at the front end of the pillow bottom ballast digging chain and the slope ballast digging chain, and the angle of the ballast gathering plate is adjustable;

[0020] The ballast gathering range is changed by adjusting the angle of the ballast gathering plate, thereby changing the ballast digging amount of the pillow bottom ballast digging chain and the slope ballast digging chain to adapt to actual operation requirements.

[0021] Preferably, the support seat is mounted on a locomotive, and the ballast unit is connected to the support seat via the support shaft.

[0022] Preferably, the lateral movement assembly is composed of two sets of telescopic devices, one in front and one behind.

[0023] Compared with the prior art, the advantages of the present invention are:

[0025] 2. The front-to-back staggered arrangement has a high excavation efficiency. When used with a knife plate, the ballast excavated by the knife plate can be transported away. At the same time, it is equipped with a ballast gathering plate. The excavation chain rotates quickly and has a high excavation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
