[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a height difference measuring device for rail transit construction, including a rail joint 11 and a pair of return rails 1; the rail joint 11 is located between the pair of return rails 1; fishplates 12 are installed on the side walls of the pair of rail joints 11; multiple sets of fishplates 12 are arranged symmetrically on the side walls of the rail joints 11; connecting bolts 13 are provided in the middle of the fishplates 12; multiple sets of connecting bolts 13 are arranged evenly in the middle of the fishplates 12; a guide assembly is provided at the top of the return rails 1; a clamping assembly is provided on the return rails 1 through the guide assembly; a measuring assembly is provided on the return rails 1 through the clamping assembly; and a cleaning assembly is provided on the return rails 1 through the guide assembly; during operation, the guide assembly is clamped on the outer side wall of the return rails 1, and the clamping assembly drives the measuring assembly to approach the top of the return rails 1 and... The top of the return rail 1 contacts the sliding guide component, which drives the measuring component to slide at a constant speed on the top of the return rail 1. If there is obvious jerking when the measuring component passes through the rail gap 11, it means that the two return rails 1 are not installed in an unbalanced manner and there is a height difference. A grinder is used to grind the height difference within 5cm on the left and right sides of the rail gap 11. When the guide component slides on the top of the return rail 1, it drives the cleaning component to move, and the cleaning component cleans the top of the return rail 1. Through the above structure, the sliding guide component drives the measuring component to slide on the top of the return rail 1, which forms the return rail 1 height difference measurement structure, realizes the function of measuring the height difference of a pair of rail gaps 11, solves the problem of the difficulty of the tapping method and the top pressure method, simplifies the steps of measuring the height difference of the return rail 1, and reduces the tedious grinding measurement.

Using the measuring slider 14, at one end of the rail gap 11 between the two return rails 1, the measuring slider 14 is moved to the other end of the rail gap 11 and slid continuously at a uniform speed. If there is obvious jerking, the two return rails 1 are not installed evenly and there is a height difference. Through the above structure, the setting of holding the handle 15 and moving the measuring slider 14 to slide on the rail gap 11 between a pair of return rails 1 forms a height difference measuring structure for a pair of return rails 1, realizing the function of detecting the height difference between the return rails 1.

Through the above structure, the wool brushes 41 clean the top and side walls of the return rail 1, forming a surface cleaning structure for the return rail 1, realizing the function of cleaning the surface of the return rail 1, solving the problem of dust or foreign objects adhering to the surface of the return rail 1 causing the measuring slider 14 to slide unevenly, improving the cleanliness of the surface of the return rail 1, and reducing the occurrence of abnormal wear on the measuring slider 14 or the return rail 1.

[0030] During operation, the guide component is engaged on the outer wall of the return rail 1. The clamping component moves the measuring component close to and into contact with the top of the return rail 1. The guide component slides, causing the measuring component to slide at a constant speed on the top of the return rail 1. If there is obvious jerking when the measuring component passes through the rail gap 11, it indicates that the two return rails 1 are not installed evenly and there is a height difference. Use a grinder to grind the height difference within 5cm on the left and right sides of the rail gap 11 to smooth it out. When the guide component slides on the top of the return rail 1, it drives the cleaning component to move, and the cleaning... The assembly cleans the top of the return rail 1; the measuring slider 14 is 4cm wide, 30cm to 40cm long, and 1cm thick. Using the measuring slider 14, at one end of the installation gap 11 between the two return rails 1, the measuring slider 14 is moved to the other end of the gap 11 and slid continuously at a uniform speed.
