Detailed Description

The specific embodiment of the dust sensor fixing bracket provided by the utility model is further described with reference to the accompanying drawings and examples.

As shown in figure 1, the dust sensor fixing support is mainly used for being fixed on an anchor rod of a roadway support upper part. The device specifically comprises a base 1, a supporting rod 3 and a connecting plate 4.

Preferably, the base 1 comprises a base plate 101, a first upright post, a second upright post, a third upright post and a fourth upright post are vertically arranged at four corners of the base plate 101, and preferably, a coaming plate 2 is horizontally arranged between the first upright post and the second upright post, between the second upright post and the third upright post and between the third upright post and the fourth upright post, and when the dust sensor is used, the dust sensor is placed in a frame surrounded by the base 1 and the coaming plate 2. It should be noted that, in order to facilitate the insertion, removal or maintenance of the dust sensor, the shroud 2 is not disposed between the first upright and the fourth upright, and is in an open state, as shown in fig. 2.

Preferably, the supporting rod 3 is horizontally arranged between the base 1 and the connecting plate 4, one end of the supporting rod 3 is fixed with the outer side wall of one of the coamings 2 of the base 1 through welding, and the other end of the supporting rod is fixed with the side wall of one side of the connecting plate 4 through welding, and the fixing mode of the supporting rod includes, but is not limited to, welding.

Preferably, in order to meet the requirement that the installation position of the dust sensor is not less than 0.5m from the roadway wall, the supporting rod 3 is made of a steel pipe with the pipe diameter of 32mm, and the length of the supporting rod 3 is greater than 0.5m.

Preferably, the connecting plate 4 is provided with a fixing through hole 401 for connecting a roadway support upper anchor rod.

In order to ensure the integral mechanical property of the fixed support, the base 1 is made of steel plates with the thickness of 3mm, and the coaming 2 is made of flat iron or angle iron with the width of 40mm and the thickness of 4mm.

Further preferably, the aperture of the fixing through hole 401 is 30mm, which is matched with the outer diameter size of the anchor rod.

When the tunnel supporting upper anchor rod is used, the tunnel supporting upper anchor rod corresponding to the working area is found, one end of the anchor rod penetrates through the fixing through hole 401 and then is fixed with the connecting plate 4 through the nut, then the dust sensor is placed into the base frame, and along with the working of mining, a worker only needs to detach the dust sensor fixing support and move to the next working area along the tunneling direction for installation.
