Description

Technical Field

[0001] This utility model relates to the field of cutter head cleaning technology, specifically to a cleaning device for slag accumulation on the back of a TBM cutter head. Background Technology

[0002] TBM equipment is a core construction tool in tunnel boring projects. During the tunneling process, most of the excavated rock enters the muck discharge port and is discharged outwards, while a small amount of dust enters the back of the cutterhead and accumulates. If this accumulation is not cleaned in time, it will not only accelerate the wear of the cutterhead components and reduce tunneling efficiency, but may also cause equipment failure or even shutdown for maintenance.

[0003] To address this issue, traditional cleaning methods mostly rely on periodic manual cleaning, which is often inefficient and incomplete, failing to meet the requirements of continuous and efficient TBM operation. Therefore, we propose a cleaning device for the debris accumulation on the back of the TBM cutterhead. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning device for the slag buildup on the back of a TBM cutter head, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cleaning device for slag accumulation on the back of a TBM cutter head, comprising a housing, a through area in the middle of the housing, uniformly spaced assembly grooves on the inner sidewall of the housing, a brush fixedly mounted in the assembly groove, and a slag collection mechanism fixedly mounted inside the housing.

[0006] Preferably, the number of assembly slots and brushes are matched, and the number of assembly slots is at least four, with the four assembly slots evenly distributed circumferentially around the center of the housing.

[0007] Preferably, the slag collection mechanism includes a first collection chamber and a second collection chamber, which are respectively opened in the shell, and a connecting cavity is opened between the first collection chamber and the second collection chamber. The inner sidewall of the first collection chamber is uniformly opened with collection holes that penetrate the shell.

[0008] Preferably, the first collecting cavity is annular and the second collecting cavity is arc-shaped.

[0009] Preferably, the top of the housing has an installation groove communicating with the connecting cavity, and a collection box is detachably and fixedly installed in the installation groove. The collection box includes a collection box body, a fixing net is embedded in the side wall of the collection box body, and a handle groove is provided on the top of the collection box body, and a handle plate is fixedly installed in the handle groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: A cleaning device for the back of a TBM cutterhead, used in conjunction with the cutterhead of the TBM equipment, is installed on the back of the cutterhead. During construction, the TBM cutterhead can rotate inside the housing. While the cutterhead is rotating, the accumulated debris on the back of the cutterhead is scraped off by a brush. The scraped debris can be sucked into the first collection chamber and collected and processed centrally through the collection box. Compared with the traditional manual cleaning method, this method can better maintain the back of the cutterhead and prevent dust from accumulating on the back of the cutterhead, thus affecting the construction and use of the cutterhead.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This utility model provides a technical solution: a cleaning device for the slag accumulation on the back of a TBM cutterhead, including a housing 1. The housing 1 is made of alloy material and is annular. A circular through-area 2 is opened in the middle. The through-area 2 is used for the passage of the drive structure connected to the cutterhead. The inner sidewall of the housing 1 is evenly provided with mounting grooves 3. A brush 4 is fixedly mounted in the mounting grooves 3. When the drive structure drives the cutterhead to perform digging action, the cutterhead can rotate inside the housing 1. The slag accumulation on the back of the cutterhead can be scraped by the brush 4.

[0020] The housing 1 is equipped with a slag collection mechanism 5, which can effectively collect the slag scraped by the brush 4. The slag collection mechanism 5 includes a first collection chamber 51 and a second collection chamber 52. The first collection chamber 51 is annularly opened in the inner cavity of the housing 1, and the second collection chamber 52 is arc-shaped opened in the inner cavity of the housing 1. The first collection chamber 51 and the second collection chamber 52 are fixedly connected by a connecting chamber 53 that is symmetrically distributed at the top and bottom. The inner side wall of the first collection chamber 51 is evenly provided with collection holes 54 that penetrate the housing 1. The collection holes 54 are respectively located on both sides of the assembly groove 3. The side wall of the second collection chamber 52 is provided with a connection port 55, which is used to connect to the external compressor pipeline. The negative pressure generated by the external compressor draws the slag scraped by the brush 4 into the first collection chamber 51 through the collection hole 54.

[0021] like Figure 3 and Figure 4 As shown, the side wall of the housing 1 has an installation groove 6 that communicates with the connecting cavity 53. A collection box 7 is detachably and fixedly installed in the installation groove 6 by fixing bolts. The collection box 7 is mainly used to collect the accumulated residue entering the connecting cavity 53. The collection box 7 includes a collection box body 71. A fixing mesh 72 is embedded in the side wall of the collection box body 71. The fixing mesh 72 filters the accumulated residue. A handle groove 73 is opened on the top of the collection box body 71. A handle plate 74 is fixedly connected in the handle groove 73. The embedded handle groove 73 makes it easy to take the collection box 7 out.

[0022] There are two mounting slots 6, which are symmetrically distributed vertically on the side wall of the shell 1. The number of collection boxes 7 matches the number of mounting slots 6. By setting two collection boxes 7, the accumulated residue can be collected and processed better.

[0023] Working principle: During the use of this equipment, if... Figure 6As shown, the housing 1 is fixedly mounted on the back of the cutter head of the TBM equipment. Its brush 4 is in contact with the back of the cutter head. The drive structure connected to the cutter head passes through the through area 2 in the middle. During use, as the cutter head rotates in the housing 1, the brush 4 can remove the dust on the back of the cutter head, preventing the dust from accumulating on the back of the cutter head and forming slag. The scraped dust enters the collection box 7 through the collection hole 54 and the first collection chamber 51 for collection and treatment, which facilitates the regular maintenance of the collection box 7 during subsequent construction.
