[0022] The tunnel excavation slag cleaning device provided by the utility model is explained and illustrated in detail below in conjunction with the drawings in the specification.

[0023] The tunnel excavation slag cleaning device provided by the utility model has a slag cleaning device, which can remove impurities such as coal slag, gravel, etc. at the intersection of the tunnel side wall and the bottom wall at the bottom of the support frame, eliminating the need for manual cleaning, thereby improving the efficiency of tunneling construction. The utility model is described in detail below in conjunction with specific embodiments:

[0024] In some embodiments, the present invention provides a tunnel excavation slag removal device, which is mounted on a support device and performs slag removal operations within the tunnel, removing impurities such as coal slag and gravel from the triangular area where the tunnel sidewall and bottom wall intersect, thereby ensuring that the support can move in the excavation direction. The support device includes a support assembly and a top guard frame, the top guard frame being mounted on the top of the support assembly, the bottom of the support assembly being supported on the ground, and multiple support assemblies being provided along the length of the lower end.

[0025] Alternatively, as Figure 1 、 Figure 2 As shown, the support device includes a support assembly 3 and a top guardrail. Multiple support assemblies 3 are provided, each arranged vertically, with its bottom end supported on the ground and its top end supporting the top guardrail. The top guardrail is located at the top of the support assembly 3. The top guardrail includes a top beam and a cross beam. The top beam extends along the length of the tunnel. Multiple top beams are arranged parallel to each other and connected by cross beams to form a top guardrail, which provides support for the tunnel roof. Support assemblies 3 are provided on both sides of the top guardrail, close to the sidewalls of the tunnel, to provide support for the top guardrail.

[0026] A slag cleaning device is provided at the bottom of the support assembly 3 located at the front end in the excavation direction. The slag cleaning device extends toward the excavation direction. The slag cleaning device can move with the support assembly 3 and remove the residue in front before the support assembly 3 moves to ensure that the support assembly 3 can be supported on a clean ground and provide stable and reliable support for the top guardrail.

[0027] In some embodiments, the slag cleaning device includes a telescopic mechanism 1 and a shovel body 2. The shovel body 2 is connected to the telescopic mechanism 1. The telescopic mechanism 1 is used to drive the shovel plate 21 to move. The telescopic mechanism 1 drives the shovel body 2 to perform a telescopic action. During the extension process, the shovel body 2 pushes the coal slag in front to the middle position of the tunnel to clean the ground in front of the support assembly 3. The coal slag in the middle position of the tunnel is cleaned away by the tunnel boring machine.

[0028] The slag cleaning device also includes a base 31, on which the telescopic mechanism 1 is mounted. The base 31 is connected to the bottom of the support assembly 3, allowing the slag cleaning device to move synchronously with the support assembly 3. Optionally, the base 31 is a cylindrical structure, for example, a square tube structure, with the telescopic mechanism 1 mounted within the base 31, thereby reducing the footprint of the telescopic mechanism 1. In this embodiment, the base 31 forms the support base of the support assembly 3, supported on the ground. The base 31 and the support assembly 3 are integrated, further reducing the footprint of the telescopic mechanism 1 without affecting the roadway layout.

[0029] In some embodiments, the telescopic mechanism 1 includes a hydraulic cylinder 11, the cylinder body of which is located within the base 31. The telescopic mechanism 1 also includes a telescopic sleeve 12, which is connected to the hydraulic cylinder 11 and controls the telescopic sleeve 12's extension and retraction. The telescopic sleeve 12 protects the telescopic rod of the hydraulic cylinder 11 from contamination by impurities such as dust and cinders, ensuring that the hydraulic cylinder 11 can operate stably and for a long time.

[0030] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3 As shown, the shovel body 2 includes a shovel plate 21 and a connecting frame 22. The shovel plate 21 is mounted on the connecting frame 22, and the connecting frame 22 is connected to the telescopic mechanism 1. A guide surface is formed on the shovel plate 21, and the guide surface pushes the coal slag at the intersection of the tunnel floor and the side wall to the middle of the tunnel. Optionally, the shovel plate 21 is a flat plate or an arc-shaped plate, and the upper surface of the shovel plate 21 constitutes the guide surface. The guide surface is tilted at a certain angle relative to the axial direction of the hydraulic cylinder 11. The guide surface on the shovel plate 21 is tilted toward the middle of the tunnel. During the forward movement of the shovel plate 21, the shovel plate 21 causes the coal slag to be turned over and moved to the middle of the tunnel. The shape of the shovel plate 21 makes it easier to insert into the coal pile from the bottom and to push away more coal slag at one time. If there is too much coal slag, the cleaning operation can be completed by multiple telescopic movements.

[0031] The connecting frame 22 is connected to the back of the shovel plate 21. A connecting section 23 connected to the telescopic mechanism 1 is formed on the connecting frame 22. The connecting section 23 is a bending structure, through which an angle is formed between the shovel plate 21 and the axis of the telescopic mechanism 1 and the hydraulic cylinder 11.

[0032] A slag cleaning device is provided on each of the support assemblies 3 at the front ends of both sides. The shovel plates 21 on the two slag cleaning devices are inclined in opposite directions, and both shovel plates 21 are inclined toward the middle of the tunnel.

[0033] The slag cleaning device can move forward synchronously with the support assembly 3 and clean the coal slag when the support assembly 3 is in a stationary state. When the support assembly 3 moves forward, the telescopic mechanism 1 is in a retracted state to avoid affecting the forward movement of the support assembly 3. Optionally, the slag cleaning device can perform the slag cleaning operation before the support assembly 3 moves, that is, time is reserved for the slag cleaning operation before the movement. Alternatively, the slag cleaning device can be performed synchronously with other operations, eliminating the need for a separate slag cleaning operation, thereby achieving the effect of improving excavation efficiency.
