Description

Technical Field

[0001] This utility model relates to the field of tunnel excavation technology, specifically a soil removal device for tunnel excavation. Background Technology

[0002] Tunnels are structures built underground, underwater, or within mountains to facilitate the passage of railways or highways for motor vehicles. Based on their location, they can be categorized into three main types: mountain tunnels, underwater tunnels, and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten distances and avoid steep gradients; underwater tunnels pass under rivers or straits to cross them; and urban tunnels are those that pass underground within cities to accommodate railways passing through large urban areas. Tunnel excavation methods are divided into cut-and-cover and tunnel-to-cover methods. Cut-and-cover methods are mostly used for shallow-buried tunnels or urban railway tunnels, while tunnel-to-cover methods are more common for mountain railway tunnels. Based on the size and location of the excavation cross-section, there are partial excavation methods and full-face excavation methods. Drill-and-blast methods are most widely used in rocky strata, and direct excavation using tunnel boring machines is also gradually being promoted. Shield tunneling methods are more commonly used in soft geological conditions.

The side of the support frame 201 is provided with a transmission gear b204, which meshes with the drive roller 202 and the driven roller 205 to drive the multiple conveyor chain plates 207 to rotate. Multiple soil cleaning devices can be connected end to end through the connecting block 101 and connecting groove 102 at the bottom of the base 1. The drive roller 202 is connected to the driven roller 205 inside another support frame 201 through the transmission gear b204 on the side of the support frame 201, so that the conveyor chain plates 207 in the multiple soil cleaning devices can be driven to rotate simultaneously, and the length of the device can be adjusted according to the usage requirements.

[0032] The desired effect of this embodiment is that when the two bases 1 are connected end to end, the connecting block 101 is inserted into the connecting groove 102. Both the connecting block 101 and the connecting groove 102 have holes for fixing. Then, the connecting block 101 and the connecting groove 102 are connected by passing bolts through the holes, so that the length of the device can be adjusted according to the usage requirements, thereby improving the applicability of the device.

[0033] Example 2

[0034] Please see Figure 2 , Figure 3 and Figure 4 This embodiment provides a technical solution: a soil clearing device for underground excavation, comprising a conveying unit 2, a support frame 201, and a drive roller 202.

[0035] A rotating groove is provided inside the support frame 201. The driving roller 202 and the driven roller 205 are embedded in the rotating groove and rotatably connected to the support frame 201. A motor 211 is provided on the side of the support frame 201. The output end of the motor 211 is connected to the driving roller 202. The motor 211 can drive the driving roller 202 to rotate inside the support frame 201. Through the transmission of the conveyor chain plate 207, the driven roller 205 can be driven to rotate inside the support frame 201. It should be noted that when multiple soil cleaning devices are connected end to end, only one soil cleaning device has a motor 211 next to it. The motor 211 drives all the conveyor chain plates 207 to rotate through the gear transmission. A transmission gear a203 is provided at one end of the driving roller 202. The transmission gear a203 meshes with the transmission gear b204. The transmission gear a203 is located next to the transmission gear b204, allowing the transmission gear a203 to drive the transmission gear b204 to rotate. A drive gear c206 is provided at one end of the driven roller shaft 205. The drive gear c206 meshes with the drive gear b204, allowing the drive gear b204 to drive the drive gear c206 to rotate. Two protective covers are provided on the side of the support frame 201. The drive gears a203 and b204 are located in the same protective cover, while the drive gear c206 is located in a separate protective cover. This provides protection and prevents soil from falling between the gears and affecting their transmission. Baffles 208 are provided on the surface of the conveyor chain plate 207. Several baffles 208 are embedded on the surface of the conveyor chain plate 207, which can improve the conveying efficiency of the conveyor chain plate 207 for soil. A docking protrusion 209 is provided on the side of the support frame 201, and a docking groove 210 is provided on the other side of the support frame 201. The docking protrusion 209 and the docking groove 210 are engaged and connected, allowing multiple support frames 201 to be connected end to end through the docking protrusion 209 and the docking groove 210.

[0036] The desired effect of this embodiment is that when multiple support frames 201 are connected end to end, the drive roller 202 can be connected to the driven roller 205 inside the other support frame 201 by meshing the drive gear b204 on the side of the support frame 201 with the drive gear c206 on the side of the other support frame 201, so that the conveyor chain plates 207 installed in multiple soil cleaning devices can be driven to rotate simultaneously.

[0037] Working principle: First, multiple soil cleaning devices are moved to the desired location using the handrails and casters 103 on the side of the support frame 201. When the two bases 1 are connected end to end, the connecting block 101 is inserted into the connecting groove 102. Both the connecting block 101 and the connecting groove 102 have holes for fixing. Then, the connecting block 101 is connected to the connecting groove 102 by bolts passing through the holes, so that multiple soil cleaning devices are connected end to end. When the connecting block 101 is inserted into the connecting groove 102, the mating protrusion 209 and mating groove 210 on the side of the support frame 201 can improve the stability of the multiple support frames 201 when connected end to end. When multiple support frames 201 are connected end to end, the transmission gear b204 on the side of the support frame 201 meshes with the transmission gear c206 on the side of another support frame 201, so that the drive roller 202 can be connected to the other support frame 201. The driven rollers 205 inside a support frame 201 are connected together, allowing the conveyor chain plates 207 inside multiple soil cleaning devices to be driven to rotate simultaneously. This allows the length of the device to be adjusted according to usage requirements. Two protective covers are provided on the side of the support frame 201. The transmission gears a203 and b204 are located in the same protective cover, while the transmission gear c206 is located in a separate protective cover, which serves to prevent soil from falling between the gears and affecting their transmission. Then, the motor 211 drives the drive roller 202 to rotate inside the support frame 201. Through the transmission of the conveyor chain plates 207, the driven rollers 205 can be driven to rotate inside the support frame 201. It should be noted that when multiple soil cleaning devices are connected end to end, only one soil cleaning device has a motor 211 next to it. Through the transmission of the gears, the motor 211 drives all the conveyor chain plates 207 to rotate.
