Detailed ways

In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

Referring to Fig. 1 to Fig. 3, the dust removal system described in this embodiment can be quickly moved on the front of the rock roadway fully mechanized excavator, which is set in the rock roadway. In the rock roadway, there are excavation equipment such as a fully mechanized excavator 2, a second-running loader 3, a belt conveyor 4, and a cable car 5, as well as an air supply duct 6 for supplying air to the rock roadway. Adjustable windshield 7 is arranged. The dust removal system is connected to the top wall of the rock roadway and is located above the above-mentioned excavation equipment.

Described in this embodiment is a dust removal system for rapid movement on the head of a fully mechanized excavator in a rock roadway, including a track device and a dust removal device.

The track device includes a slide rail 111 and a slide rod 112 . The side of the slide rail 111 facing the top wall of the rock roadway is provided with a suspension ear 113 . On the top wall of the rock roadway, there are lifting anchors or supporting anchor cables along its direction. These lifting anchors or supporting anchor cables can be used as the fixed rods 113 for installing the slide rail 111, and the supporting anchor cables are used as the fixed rods 113 below. Take this as an example. The length of the supporting anchor cable exposed to the top wall of the rock roadway is not less than 100mm, and it is connected with the slide rail 111 through an anchor chain (not shown in the figure). One end of the anchor chain passes through the exposed part of the supporting anchor cable, and then the anchor cable The nut or the anchor cable lock is locked firmly, and the other end passes through the suspension ear 113, and is connected with the slide rail 111 by a track connecting pin (not shown in the figure). As preferably, the track connecting pin here uses an elastic cotter pin. One end of the slide rail 111 away from the excavation surface of the rock roadway is provided with a load-carrying trolley 114, the load-carrying trolley 114 is connected with a power unit 115, and the lower end of the load-carrying trolley 114 is provided with a hook; the slide rail 111 is also provided with a pulley 116, and the pulley 116 is located on the bearing The trolley 114 faces the side of the rock roadway driving face. The sliding rod 112 is connected to the pulley 116 through an anchor chain, so that it can move along the sliding rail 111 .

The dust removal device includes a dust removal fan 121 and a skeleton air duct 122 . The dust removal fan 121 is hung on the hook of the carrying trolley 114 through an anchor chain, and the air inlet end of the dust removal fan 121 is set toward the rock roadway excavation face; the skeleton air duct 122 is connected with the air inlet end. Generally, the axis position of the skeleton air cylinder 122 is higher than the axis of the air inlet end of the dust removal fan 121 , therefore, the skeleton air cylinder 122 is connected with the air inlet end through the air cylinder elbow 123 . Because the skeleton air duct 122 is a negative pressure air duct, in order to avoid it being sucked by the wind pressure, the skeleton air duct 122 is generally a hard air duct formed by a supporting frame (not shown) in a conventional flexible air duct. The blower 122 is suspended on the sliding rod 112 by a hanging rope, and is arranged parallel to the blower blower 6 .

In order to balance the tensile force on the dust removal fan 121, it is suspended on the slide rail 111 by two load trolleys 114, and the two load trolleys 114 are respectively arranged at both ends of the dust removal fan 121, and the power unit 115 is located between the two load trolleys 114 , and arranged on the slide rail 111, the power unit 115 is connected with two carrying trolleys 114 at the same time. In this embodiment, the power device 115 used to push the trolley 114 to move back and forth is a pneumatic power device, that is, the power device 115 and the slide rail 111 form a pneumatic monorail crane, and its structure is a conventional prior art, so it will not be repeated here.

When the power device 115 pushes the carrying trolley 114 to move, the carrying trolley 114 drives the dust removal fan 121 to move, and transmits power to the pulley 116 through the skeleton air duct 122 and the sliding rod 112, so that the pulley 116 slides on the slide rail 111.

Next, the installation and use of the dust removal system will be introduced in detail by taking the wind power device as the traction power source as an example.

Firstly, the slide rail 111 with the pulley 116 is installed by using the lifting anchor rod or supporting anchor cable. In order to ensure a sufficient working surface, the distance between the bottom surface of the slide rail and the ground of the rock roadway is not less than 2.8m, and the two sides of the slide rail 111 reach the rock roadway. There should be a gap of not less than 0.85m on the corresponding side wall, and the distance from the end of the slide rail 111 towards the rock roadway excavation face to the rock roadway excavation face is not more than 5m. Then install the carrying trolley 114, so that the carrying trolley 114 is slidably connected with the slide rail 111. Then assemble the wind power device and connect it with the carrying trolley 114 .

Introduce high-pressure gas for trial operation, and observe whether the carrying trolley 114 and the pulley 116 drive the sliding rod 112 to run flexibly, and whether the pipeline is leaking.

After the trial operation is qualified, assemble the skeleton air duct 122 and the dust removal fan 121, then hang the dust removal fan 121 on the hook of the carrying trolley 114 through the anchor chain, hang the sliding rod 112 on the sliding rail 111 through the pulley 116, and make the sliding rod 112 is connected with skeleton air duct 122.

When the fully mechanized excavator 2 is cutting or shipping, the power unit 115 is turned on, and the load-carrying trolley 114 is pushed to move toward the excavation surface of the rock roadway, and the dust removal fan 121 and the skeleton air duct 122 are moved to the end of the skeleton air duct 122 near the excavation surface of the rock roadway. It can stop when the distance from the top of the road to the driving face of the rock roadway is less than 5m. Then open the adjustment windshield 7 on the air supply air cylinder 6, so that the air supply volume is less than the air output of the dust removal fan 121, and then start the spray system of the dust removal fan 121 to prepare for dust removal.

After the fully-mechanized excavator 2 starts, start the construction work after turning on the dust removal fan 121 and the internal and external spraying and high-pressure spraying of the fully-mechanized excavator 2. After the construction work is finished, close the dust removal fan 121 and adjust the windshield 7, and then turn on the power unit 115 to pull the dust removal fan 121 and the skeleton air duct 122 away from the rock roadway excavation face.

During the forward and backward movement of the carrying trolley 114, in order to avoid derailment, both ends of the slide rail 111 are provided with a limit device 117. The limit device 117 in this embodiment is formed by winding a rope on the slide rail 111.

As the depth of excavation increases, the slide rail 111 needs to be extended forward. At this time, only the slide rail 111 at the rear needs to be dismantled and moved to the front end for re-suspension.

Through the cooperation of the track device and the dust removal device, the present invention fundamentally solves the channel adjustment phenomenon during the removal process of the dust removal fan 121, realizes the rapid removal of the dust removal fan 121, and eliminates potential safety hazards during the removal process.

The technical solution of the present invention has exemplarily described the invention above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned method, as long as various insubstantial improvements made by the method concept and technical solution of the present invention are adopted, Or directly applying the concept and technical solution of the invention to other occasions without improvement is within the protection scope of the present invention.
