A multi-functional self-propelled anchor-support integrated machine behind the roadheader

Abstract

The invention discloses a multifunctional self-propelled anchor-support integrated machine behind a roadheader, which solves the problems in the prior art that various mechanisms in roadways and tunnels are arranged separately, occupy a large space, cannot be moved forward as a whole, and support construction efficiency is low , the ventilation and dustproof effect and the support efficiency have been effectively improved. The technical scheme is as follows: the all-in-one machine includes an anchor-support self-propelled mechanism, and the anchor-support self-propelled mechanism includes a chassis and a support frame. There are at least two bolt drill arms on the support frame for drilling bolt and cable holes and installing the bolt and cable. The tail of the bridge belt transfer machine is equipped with a discharge hopper. The bucket is in front of the working platform, and the unloading bucket at the tail of the machine is hinged with the belt frame under the working platform. There are belt rollers on the slope, and a ventilation and dustproof mechanism on the side of the support frame.

Description

technical field [0001] The invention relates to the support of underground engineering roadways and tunnels, in particular to a multifunctional self-propelled anchor-support integrated machine behind a boring machine. Background technique [0002] When using arm-type roadheaders to construct underground roadways and tunnels, in order to increase the construction speed of roadways and tunnels, it is necessary to drill bolt and anchor cable holes after the roadheader and install the bolt and anchor cables. In the prior art, due to the There are reloading belt conveyors and push-in and pull-out air ducts fixed on the side of the roadway and tunnel, which cause the space in the roadway and tunnel to be narrow.

Problems solved by technology

[0002] When using arm-type roadheaders to construct underground roadways and tunnels, in order to increase the construction speed of roadways and tunnels, it is necessary to drill bolt and anchor cable holes after the roadheader and install the bolt and anchor cables. In the prior art, due to the There are reloading belt conveyors and push-in and pull-out air ducts fixed on the side of the roadway and tunnel, which cause the space in the roadway and tunnel to be narrow. When the roadway and tunnel are supported by a support mechanism, the support mechanism can only be set On the side of the reloading belt conveyor, it occupies a large area. If the roadway and tunnel section are small, it is not easy to use the machine to support the roadway and tunnel; second, because the support mechanism is located on the side of the belt conveyor, the support Mechanism support can only support one side of the roadway and tunnel, and it is difficult to support the other side with a support mechanism; thirdly, the push-in and draw-out air ducts in the roadway and tunnel are usually suspended on both sides of the roadway and tunnel. To install the anchor rod and anchor cable here, it is necessary to remove the air duct hanging on the lane side, and then hang it up after installing the anchor rod and anchor cable, which increases manual repetitive labor; fourth, the press-in air duct Hanging on the side of the road, it cannot move forward synchronously with the roadheader. The outlets of the two air ducts and the positions relative to the head of the excavation are not fixed.
