Description

Device for drilling and sampling and measuring ballast bed depth by using ballast bed

Technical Field

The utility model relates to a drilling equipment field especially relates to an utilize equipment of railway roadbed probing sample and measurement railway roadbed degree of depth.

Background

At present, the operation mode of manually scraping the ballast is still adopted on the railway, and no corresponding mechanical equipment is used. The operation mode is characterized as follows:

1. the manual operation efficiency is lower.

1) At present, the condition of the ballast bed (whether the ballast bed is turned over or not and is dirty or not in the depth of 30-35cm below the bottom of a sleeper) needs to be investigated in detail in the quarter inspection of ballast bed overhaul and railway maintenance, and at present, the ballast bed is dug by a manual three-tooth scratcher and a crow bar in a main investigation mode to check whether the ballast bed is turned over or not. And (3) surveying for about 3-5 minutes according to 2-3 persons at each position of the labor condition, performing spot inspection every 100 meters on the site, if slurry is turned, performing encrypted survey, and judging the starting and finishing points of the throwing operation (large machine operation, except clean ballast on the surface of the ballast bed, all dirty ballast within 35cm of the sleeper bottom is thrown). And if no slurry is turned, cleaning the screen. The investigation operation speed is about 1-2km/h, and only a track bed can be taken off in a skylight point (no vehicle exists on a line in the time period, the skylight point time is different by 2-3 h/day according to the line grade, namely the investigation speed of the daily progress is about 2-3 km/d) at the present stage.

2) The method also has measurement requirements for the thickness of the stone ballast on the simply supported beam bridge to be used as a characteristic point of slope pulling design (the specification requires that the thickness of the stone ballast under a simply supported beam bridge sleeper is at least 25cm when the maximum speed v of a line is less than or equal to 120km/h, and the thickness of the stone ballast under the simply supported beam bridge sleeper is at least 30cm when the maximum speed v of the line is more than or equal to 120km/h and less than or equal to 160 km/h). The current operation mode is as follows: the ballast is taken off to the scene manual work, uses the crowbar to insert to the bridge floor, and the length of the lower crowbar of sleeper bottom i.e. the bridge floor is to the thickness of beam face (the bridge upper beam face piece is more, often tamps and inserts dozens of times and just can reach the beam face) to the artifical steel ruler that utilizes. If the thickness is investigated on site and the design requirement is not met, the track starting design is needed during the slope drawing design.

Similar devices exist on the market:

the pit digger is similar to other existing pit diggers but different from the existing pit diggers, and the power of the pit digger is smaller. The center of a drill bit of the pit digger firstly touches the ground, the drill bit rotates by taking the center as an original point, and the drill bit cannot drill when encountering stone ballast during drilling a track bed. In addition, if the traditional electric drill is used for operation, when the stone ballast is drilled to the thickness of 30-40cm, the effect of sampling cannot be achieved, whether the pavement slab is a slab surface or a beam surface cannot be clearly distinguished on a bridge, the effect of measuring the depth cannot be achieved, and the stone ballast is broken to cause damage.
