Description

Technical Field

[0001] The invention belongs to the technical field of railway engineering vehicles, and in particular relates to a vertical integrated cold-proof water tank structure used in a rail flaw detection vehicle. Background Art

[0002] The flaw detection vehicle is a special vehicle or train for detecting rail damage on the track. Large rail flaw detection vehicles have been used in developed countries for 40 to 50 years. They have replaced manual flaw detection equipment and become the main means of detecting in-service rail damage. Ultrasonic flaw detection for rail fatigue cracks and other internal defects has the advantages of high sensitivity, fast detection speed, accurate positioning, and good economy. At present, flaw detection vehicles at home and abroad all use ultrasonic flaw detection technology. The coupling water tank used in ultrasonic flaw detection vehicles is mostly made of stainless steel, and is designed with an on-board water tank and an under-board water tank. The on-board water tank is a water tank hung on the roof steel structure, and water is supplied by natural gravity. Its volume is generally not large to prevent the vehicle from shaking during operation; the under-board water tank is a water tank hung on the bottom steel structure of the vehicle, and water is supplied by a water pump, which has a high cost; the general in-vehicle water tank will not have a large volume due to the limited space of the in-vehicle equipment, and the antifreeze tank and the water tank exist separately, making the originally limited in-vehicle space even tighter. At the same time, there are few internal wave-breaking plates in the in-vehicle water tank, and the water tank skin will collapse after long-term use, resulting in water leakage; traditional water tank level gauges, inspection ports, etc. all protrude from the outer surface of the water tank, affecting the layout of indoor facilities, which is extremely unsightly; some rail engineering vehicle water tanks are only designed for single-side water injection. If the vehicle parking position (high platform) does not meet the side water injection, it is difficult to add water. For example, the patent number is 201821849347.3, and the patent name is "New Water System for Metro Rail Flaw Detection Vehicle" (hereinafter referred to as the comparative document), which discloses a water system for rail flaw detection vehicles, and specifically discloses a coupled water tank. Although the comparative document solves technical problems such as difficulty in single-sided water injection and small volume, when in use, the coupled water tank and the antifreeze water tank are split structures, resulting in the exposed antifreeze pipes and water pipes being staggered, which not only affects the appearance, but also causes inconvenience to the installation of other equipment. In addition, the coupled water tank body itself has poor antifreeze and thermal insulation properties. When encountering a cold environment, the water tank skin is very likely to collapse and leak. Therefore, it is necessary to make improvements to the above problems. Summary of the invention

[0003] The technical problem solved by the present invention is as follows: a vertical integrated cold-proof water tank structure for use in a rail flaw detection vehicle is provided, which is composed of a frame, an integrated inner box body arranged on the inner side of the frame, an outer box body arranged on the outer side of the frame, and a thermal insulation layer filled between the outer box body and the integrated inner box body. The cold-proof performance of the box body itself is effectively improved, and the cold-proof and thermal-insulating effect is good, and water leakage caused by internal freezing of the box body when the box body is in a cold environment is avoided. The structure of integrating the coupling water tank and the antifreeze tank is adopted, and the disorderly distribution of the antifreeze pipes and water pipes outside the box body is eliminated. The double sensor mounting seat and the heater mounting flange that are indented inwardly are avoided, and the influence on the installation of other equipment caused by the heater being exposed after installation is avoided, and the appearance is beautiful.
