Problems solved by technology
[0005] 1. When the cable is in a slack state, the cable may break away from the wheel surface of the guide wheel, thus causing the guide wheel to lose its guiding and supporting functions
[0006] 2. If the cable is in a state of oblique pull that is not perpendicular to the axis of the guide wheel, the cable may also be detached from the wheel surface of the guide wheel

The invention discloses an aluminum profile supporting and guiding device for drilling a cable of a shield tunneling machine of a tunnel, and the device comprises a pedestal which is made of an aluminum profile, is in a strip shape, and is fixed at the front side of a winding drum; a first wheel set; the first wheel set comprises a first support, a second support, a third wheel set and a fourth wheel set, the four first guide wheels are installed on the first support, every two of the four first guide wheels are arranged in parallel, the wheel surfaces of the four first guide wheels are enveloped to form a first hole allowing a cable to penetrate through, and the cable penetrates through the first holes and is wound around the winding drum. The cable is limited by the first hole defined bythe first wheel set, so that the cable cannot be separated from the wheel surface of the first guide wheel even if the cable is in a loose state or a cable-stayed state.
Description
technical field [0001] The invention relates to a device for supporting and guiding cables used in a shield machine. Background technique [0002] The shield machines used for drilling tunnels in the prior art mostly use electric energy as the power source. Therefore, it is necessary to use cables to electrically connect the power supply to the shield machine, and because the shield machine is a moving part, therefore, in A storage device such as a reel is installed on the shield machine to enable the cable to be retracted in time. [0003] In the prior art, a support and guide device is provided in front of the reel to guide and support the cable before it is wound on the reel, so as to minimize the messiness of the cable after it is wound on the reel. The device is usually specifically a guide wheel erected at a certain height, and the arc-shaped wheel of the guide wheel has a certain guiding and supporting effect on the cable, thereby reducing the disorder after being wo...
