Problems solved by technology

[0002] The shield machine is prone to wear and tear when digging into gravel, gravel, rock and other strata, which will greatly reduce the life of the digging cutterhead and cutter, often cause sudden changes in tunneling parameters and delay the tunneling schedule
Therefore, it is necessary to detect the wear of the cutter and the cutter of the shield machine. The existing detection methods mainly use gear detection of wear status, self-use hydraulic signal detection, etc. The above detection methods are complex in structure and high in cost

Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] see figure 1 A first preferred embodiment of a device for detecting wear of an appliance according to the present invention is shown. As shown in the figure, the device for detecting wear of an appliance includes a resistor 1 connected to a constant pressure circuit. The resistance element 1 is installed on the tool 2 to be tested and can be worn synchronously with the tool 2. The tool 2 is usually made of metal, such as a tool for cutting or a cutter head for installing a tool. figure 1 , the direction indicated by the arrow is the wear direction of the appliance 2, the left end of the appliance 2 is the wear end 21, the initial position of the end of the resistance element 1 close to ...

Abstract

The invention provides a device for detecting wear of an apparatus and a shield machine provided with the same. The device for detecting the wear of the apparatus provided by the invention comprises a resistance unit which is arranged on the apparatus to be detected and can be worn synchronously along with the apparatus, wherein the resistance unit is connected to a fixed-voltage loop; the current intensity of the resistance unit corresponds to the wearing capacity of the resistance piece one by one; and the wearing capacity of the resistance unit corresponds to the wearing capacity of the apparatus one by one. In the shield machine provided by the invention, the device for detecting the wear of the apparatus is arranged. Due to the adoption of the technical scheme, the device has the advantages of simple structure, low cost and easiness for detecting.

Description

technical field [0001] The invention relates to the field of engineering machinery, more specifically, to a device for detecting wear of an appliance and a shield machine with the same. Background technique [0002] When the shield machine is excavated into gravel, gravel, rock and other strata, it is easy to wear and tear, which will greatly reduce the life of the excavation cutter head and the tool, often cause sudden changes in the excavation parameters and delay the excavation schedule. Therefore, it is necessary to detect the wear of the cutting tool and the cutting tool of the shield machine. The existing detection methods mainly use gear detection of wear status, self-use hydraulic signal detection, etc. The above detection methods are complex in structure and high in cost. Contents of the invention [0003] The present invention aims to provide a device for detecting tool wear and a shield machine with the same, so as to provide a device for detecting tool or cutte...
