Description

Technical Field

[0001] The utility model relates to the technical field of tunneling heads, in particular to a tunneling head with a lateral protection structure. Background Art

[0002] Coal is the area where humans mine coal resources in coal-rich mining areas, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal. This is an underground coal mine. A coal mine is a reasonable space dug by humans when digging a geological layer rich in coal, usually including tunnels, shafts, and mining faces, etc.

[0003] With the rapid development of energy economy, the demand for tunneling heads of coal mine boring machines is increasing. The boring machine is a large mechanical power mining equipment required in the mining process. It generally breaks the wall of the mine through the high-speed rotating tunneling head to achieve the excavation in the mining process. At present, when the boring machine is not in use or in the process of transfer, the tunneling head has no protective device, which may touch hard objects during the movement, causing damage to the drill bit. In addition, the size and weight of the tunneling head are large, and it is extremely difficult to temporarily replace the tunneling head in the mine. In view of this, we propose a tunneling head with a lateral protection structure. Utility Model Content

[0004] The purpose of the utility model is to provide a tunneling head with a lateral protection structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a tunneling head with a lateral protection structure, comprising a tunneling head body, the upper end of the tunneling head body is inserted into the interior of a mounting seat, and a protective device is provided on the outer wall of the mounting seat, the protective device comprising:

[0006] A connecting block, the connecting block is fixedly mounted on the outer wall of the mounting seat, a sliding rod passes through the connecting block and is slidably connected to the sliding rod;

[0009] Preferably, fixing blocks are fixedly mounted at the front and rear ends of the mounting seat, and a limiting device is provided on the fixing blocks.

[0010] Preferably, the limit device includes a limit rod, a limit ring, a pull block and a limit spring, the limit rod passes through the fixed block and the mounting seat and is slidably connected to the fixed block and the mounting seat, the limit ring is fixedly installed on the outer wall of the limit rod, the end of the limit ring away from the mounting seat is fixedly connected to the limit spring, the limit spring is sleeved on the outer wall of the limit rod, the end of the limit spring away from the limit ring is in contact with the fixed block, and the end of the limit rod away from the center line of the mounting seat is fixedly connected to the pull block.

[0011] Preferably, a limiting groove is provided on the tunneling head body, and the limiting groove is matched with the limiting rod, so that the limiting rod is inserted into the limiting groove, and the tunneling head is quickly fixed and limited, which is convenient for installation.

[0013] Preferably, the bottom of the protective plate is arranged as an inclined surface to reduce the area in contact with the coal mine.

[0014] Compared with the prior art, the utility model provides a tunneling head with a lateral protection structure, which has the following beneficial effects:

[0015] 1. The tunneling head with a lateral protection structure is provided with a protection device. When the tunneling machine is not in use or in the process of transfer, the sliding rod drives the protection plate to move downward through the elastic potential energy of the telescopic spring, so that the two sets of protection plates can protect the tunneling head body inside to prevent it from being touched during the movement.

[0016] 2. The tunneling head with a lateral protection structure is provided with a limiting device. When the tunneling head body needs to be replaced, the pull block is pulled to move the limiting rod outward. At this time, the limiting rod is no longer inserted into the limiting groove of the tunneling head body, which facilitates the removal of the tunneling head body from the inside of the mounting seat and the installation of a new tunneling head body into the mounting seat, thereby achieving the purpose of quick replacement and simple and convenient operation.

[0022] Specifically, the protective device 3 of the technical solution of the utility model includes a connecting block 301, a sliding rod 302, a protective plate 303, a sliding block 304 and a telescopic spring 305. The elastic potential energy of the telescopic spring 305 drives the sliding rod 302 and the protective plate 303 to move downward, so that the two sets of protective plates 303 protect the tunneling head body 1 to prevent the tunneling head body 1 from being hit when the tunneling machine is not in use or in the process of transfer, thereby protecting it.

[0023] In one embodiment of the present invention, two sets of protection plates 303 can wrap the boring head body 1 inside.

[0024] Please continue reading Figure 1-Figure 3The front and rear ends of the mounting seat 2 are fixedly installed with a fixing block 201, and a limiting device 4 is arranged on the fixing block 201. The limiting device 4 includes a limiting rod 401, a limiting ring 402, a pull block 403 and a limiting spring 404. The limiting rod 401 passes through the fixing block 201 and the mounting seat 2 and is slidably connected to the fixing block 201 and the mounting seat 2. The limiting ring 402 is fixedly installed on the outer wall of the limiting rod 401. The end of the limiting ring 402 away from the mounting seat 2 is connected to the limiting spring The spring 404 is fixedly connected, the limit spring 404 is sleeved on the outer wall of the limit rod 401, the end of the limit spring 404 away from the limit ring 402 is in contact with the fixed block 201, the end of the limit rod 401 away from the center line of the mounting seat 2 is fixedly connected to the pull block 403, and a limit groove 101 is provided on the excavation head body 1, the limit groove 101 is adapted to the limit rod 401, the upper end of the mounting seat 2 is fixedly installed with a drive shaft 5, and the bottom of the protective plate 303 is set as an inclined surface.

[0025] In the implementation mode of the utility model, in order to facilitate and faster installation of the tunneling head body 1, by inserting the upper end of the tunneling head body 1 into the interior of the mounting seat 2, and then inserting the limiting rod 401 into the limiting groove 101, the tunneling head body 1 can be quickly fixed and limited, and the operation is simple and convenient.

[0026] During operation (or use), when the tunnel boring machine is in a non-use state or in the process of transfer, the tunnel boring head body 1 is driven to move, which drives the sliding rod 302 and the protective plate 303 to move downward through the elastic potential energy of the telescopic spring 305. The two sets of protective plates 303 can protect the tunnel boring head body 1 inside and protect the tunnel boring head body 1. When the tunnel boring head body 1 is working, the mounting seat 2 is driven to rotate through the drive shaft 5, so that the tunnel boring head body 1 at the lower end is also rotated. At this time, the tunnel boring head body 1 is in contact with the wall of the mine, and the protective plates 303 on both sides are also in contact with the wall of the mine, and squeeze the protective plates 303, so that the protective plates 303 drive the sliding rod 302 and the sliding block 304 to move upward. When the protective plates 303 move upward, the tunnel boring head body 1 can be exposed, which is convenient for the tunnel boring head body 1 to work.
