Description

Technical Field

[0001] The invention relates to the technical field of underground pipeline detectors, in particular to a digital underground pipeline detector with an obstacle avoidance alarm structure. Background Art

[0002] Underground pipeline detectors can quickly and accurately detect the location, direction, depth, and location and size of damaged points of the anti-corrosion layer of underground water pipes, metal pipes, cables, etc. without damaging the ground cover. They are widely used by water companies, gas companies, and other units to renovate, repair, and survey underground pipelines. However, existing digital underground pipeline detectors still have the following shortcomings:

[0003] 1. Existing digital underground pipeline detectors usually use roller carts to carry the detection equipment. This walking method is only suitable for the detection of pipelines on better paved roads, and cannot be used on some unpaved roads with poor road conditions, making its applicability poor;

[0004] 2. The existing digital underground pipeline detector is not convenient for automatically marking the detected pipeline path. The existing digital underground pipeline detector needs to manually mark the detected pipeline position during the detection process, which is time-consuming and laborious, resulting in low efficiency of pipeline detection;

[0005] Therefore, a digital underground pipeline detector with an obstacle avoidance alarm structure is needed to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a digital underground pipeline detector with an obstacle avoidance alarm structure to solve the problems of poor applicability and low pipeline detection efficiency of the existing digital underground pipeline detectors mentioned in the above background technology.

[0010] A push handle, the push handle is fixedly connected to the right end surface of the bearing plate;

[0011] A detection display screen, wherein the detection display screen is fixedly connected to the upper side of the push handle;

[0012] A support frame, the support frame is fixedly connected to the front and rear sides of the bottom of the carrying plate;

[0013] A lifting drive gear, the lifting drive gear is connected to the inner middle position of the support frame through a shaft;

[0014] A rack, the rack being arranged at the left and right sides of the lifting drive gear, and the rack and the lifting drive gear being meshed and connected with each other;

[0016] A crawler walking mechanism, wherein the crawler walking mechanism is arranged on the lifting slider at the front side of the support frame;

[0060] 1. By shaking the handle, the worm is driven to rotate, and the rotation of the worm drives the worm wheel to rotate, so that the worm wheel drives the lifting drive gear on the front side of the carrier plate to rotate through the sprocket transmission mechanism, and the lifting drive gear on the front side of the carrier plate drives the lifting drive gear on the rear side of the carrier plate to rotate synchronously through the intermediate shaft, so that the lifting drive gears on the front and rear sides of the carrier plate rotate to drive the racks on both sides to move up and down, and the lifting movement of the rack drives the crawler walking mechanism and the roller walking mechanism to move up and down through the lifting slider, so that it is convenient to switch the walking mode, which can effectively improve the detection applicability of the digital underground pipeline detector;

[0061] 2. When the track wheel or the fixed wheel rotates, it can drive the driven shaft to rotate. The driven shaft rotates through the transmission belt to drive the rotating frame to rotate, so that the rotating frame drives the extrusion sleeve to squeeze the flexible hose, thereby supplying the ink in the funnel into the ink nozzle, and the ink is sprayed out through the ink nozzle to mark the pipeline path, so that the pipeline path can be automatically marked, thereby improving the detection efficiency of the digital underground pipeline detector.
