Abstract
Description
Technical Field
[0001] This utility model belongs to the field of railway track maintenance technology, and in particular relates to an electric sleeve sand cleaning tool. Background Technology
[0002] Railway tracks can be classified into ballasted tracks and ballastless tracks according to their track bed structure. Ballasted tracks are widely used in conventional lines, high-speed railways, urban rail transit, and station lines. Ballast track fasteners are classified into two structural types according to the sleeper connection method: embedded spikes and embedded sleeves. The embedded sleeve structure typically uses embedded sleeves in conjunction with spiral spikes or anchor bolts, offering advantages such as convenient installation, high strength, strong lateral force resistance, and low maintenance workload.
[0003] However, during use, pre-embedded pipe sleeve structures inevitably experience blockages caused by mud, sand, and gravel, especially on ballasted lines and in western areas with high wind and sandstorms. This can lead to improper bolt installation, or even prevent bolt installation altogether, affecting track structural strength and train safety. Currently, maintenance personnel use tools such as wire, screwdrivers, and electric drills to remove the sand. This method is slow and inefficient, and cannot quickly complete the required work within the limited maintenance window. In some cases, severe blockages cannot be completely resolved, preventing the installation of track spikes. Utility Model Content

[0028] The front end of the machine body has a drill rod channel extending in a front-to-back direction, which communicates with the drill rod drive chamber. The hollow drill rod 2 passes through the drill rod channel and is rotatably engaged with the machine body 1 via two front-to-back first bearings 21. The rear end of the hollow drill rod 2 extends to the partition plate 4, and a connecting through hole 5 is provided at a corresponding position on the partition plate 4, which communicates with the rear end of the hollow drill rod 2. The front end of the hollow drill rod 2 extends outward from the machine body 1, and the hollow drill bit 3 is coaxially mounted on the front end of the hollow drill rod 2, and the two are detachably connected.
[0029] A drill pipe drive mechanism is provided in the drill pipe drive chamber. In this embodiment, the drill pipe drive mechanism is a drill pipe motor 6, which is a DC brushless motor. The drill pipe motor 6 is connected to the hollow drill pipe 2 for transmission.
[0030] The dust collection chamber is equipped with a filter screen 7, and the area between the front side of the filter screen 7 and the partition 4 forms a dust accumulation chamber 8; the dust collection chamber area behind the filter screen 7 serves as the suction mechanism installation chamber, and the suction mechanism is installed in the suction mechanism installation chamber.
