Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices, specifically an auxiliary dust suppression device for tunneling machines. Background Technology

[0002] Dust control in mines includes spraying dust to suppress the large amount of dust generated by tunneling machines. However, because the working face of tunneling machines is generally a blind tunnel, and such tunnels are usually quite narrow, and the dust-generating area of ​​tunneling machines is characterized by high gas emission, large ventilation volume, and high wind speed, auxiliary dust suppression devices for tunneling machines are often used in the mining process.

[0003] However, existing tunneling machines have the following disadvantages:

[0004] (1) During the coal mining process, a large amount of dust will be splashed up, causing personnel to work in a dusty environment for a long time, which poses a safety hazard to personnel.

[0005] (2) It is inconvenient for personnel to easily assemble and disassemble the dust suppression equipment, which makes maintenance more complicated and causes inconvenience to personnel. Therefore, this utility model provides an auxiliary dust suppression device for tunneling machines. Utility Model Content

[0007] In view of the shortcomings of the prior art, this utility model provides an auxiliary dust suppression device for tunneling machines, which solves the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary dust suppression device for a tunneling machine, comprising a first water guide pipe and a second water guide pipe. The first and second water guide pipes are both semi-circular, with their ends in contact to form an annulus. Connecting ears are fixedly connected to the outer sides of both ends of the first and second water guide pipes. First bolts are inserted along the connecting ears on the two first and second water guide pipes, and nuts are installed on the first bolts to fix the first and second water guide pipes. Multiple threaded pipes are provided inside the first and second water guide pipes, and second bolts are installed on the threaded pipes to fix the dust suppression device on the tunneling machine. A connecting pipe is installed on one side of the second water guide pipe, and the end of the connecting pipe is connected to the outlet of the water pump. Water spraying components are installed on the other side of the second water guide pipe and on the first water guide pipe on the same side.

[0010] Furthermore, the water spray component includes an extension pipe, one end of which is disposed in a first water guide pipe or a second water guide pipe, and the other end is equipped with a nozzle.

[0011] Furthermore, the extension pipe is inclined outward on the first or second water guide pipe.

[0012] Furthermore, both ends of the first water pipe are equipped with tubular plugs for insertion into the second water pipe.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an auxiliary dust suppression device for tunneling machines, which has the following features:

[0015] Beneficial effects:

[0016] The auxiliary dust suppression device for this tunneling machine consists of a first water guide pipe, a second water guide pipe, and a water spray nozzle connected to them. Under the action of a water pump, water can enter the water guide pipe through the connecting pipe and be sprayed out by the nozzle. This effectively suppresses the dust generated by the tunneling head crushing materials, greatly improves the working environment, reduces the time workers spend in a dusty environment, lowers the safety hazards caused by dust, and protects the health of the workers.

[0017] Second, the first and second water guide pipes in the device are connected and fixed by connecting ears, first bolts and nuts. At the same time, the threaded pipe and second bolts are used to fix the entire device to the tunneling machine. This connection method is simple in structure and convenient to operate. It is easy for workers to assemble and disassemble the dust suppression device. When the equipment fails and needs to be repaired, the corresponding operation can be completed quickly, which greatly reduces the cumbersomeness of maintenance and improves the convenience of use.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention relates to an auxiliary dust suppression device for a tunneling machine, comprising a first water guide pipe 1 and a second water guide pipe 2. The first water guide pipe 1 and the second water guide pipe 2 are both semi-circular, and their two ends are in contact with each other to form an annulus. Connecting ears 4 are fixedly connected to the outer sides of both ends of the first water guide pipe 1 and the second water guide pipe 2. A first bolt 5 is inserted along the connecting ears 4 on the two first water guide pipes 1 and the second water guide pipe 2, and a nut 6 is installed on the first bolt 5 for fixing the first water guide pipe 1 and the second water guide pipe 2 on the tunneling machine. Multiple evenly distributed threaded pipes 7 are fixedly connected inside the first water guide pipe 1 and the second water guide pipe 2. The threaded pipes 7 form openings on the inner and outer walls of the first water guide pipe 1 or the second water guide pipe 2. A second bolt 8 is installed along the opening of the threaded pipe 7. Rotating the second bolt 8 fixes the dust suppression device on the tunneling machine.

[0026] A connecting pipe 9 is installed on one side of the second water pipe 2. The end of the connecting pipe 9 is connected to the outlet of the water pump. A water spraying component 3 is installed on the other side of the second water pipe 2 and on the first water pipe 1 on the same side.

[0027] The water spray component 3 includes an extension pipe 11. One end of the extension pipe 11 is disposed on the first water guide pipe 1 or the second water guide pipe 2, and the other end is equipped with a nozzle 12. The extension pipe 11 is inclined outward on the first water guide pipe 1 or the second water guide pipe 2, which not only increases the area of ​​water sprayed by the nozzle 12.

[0028] Both ends of the first water pipe 1 are provided with tubular plugs 10 for insertion into the second water pipe 2. The plugs 10 are made of rubber. When they are inserted into the second water pipe 2, they seal the connection between the first water pipe 1 and the second water pipe 2, preventing water from flowing out from the corresponding positions of the first water pipe 1 and the second water pipe 2.

[0029] In summary, the auxiliary dust suppression device for the tunneling machine is used by placing a first water guide pipe 1 and a second water guide pipe 2 on the tunneling machine, with the two corresponding to each other, and inserting the plug 10 into the second water guide pipe 2. The first bolt 5 is inserted along the corresponding connecting lug 4, and a nut 6 is installed on the first bolt 5, so that the first water guide pipe 1 and the second water guide pipe 2 form a ring shape at the front end of the tunneling machine.

[0030] Then rotate the second bolt 8 and press it against the outer wall of the front end of the tunneling machine to fix the dust removal device.

[0031] A water pump is installed at the end of the connecting pipe 9, and the inlet of the water pump is connected to a water source. When the water pump is started, water flows along the water pump, the connecting pipe 9, into the first water guide pipe 1 and the second water guide pipe 2, and is sprayed out by the nozzle 12 to suppress the dust generated by the material being broken by the tunneling head of the tunneling machine.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
