Embodiment Construction
[0017] Such as Figures 1 to 4 As shown, the detection device for the grooved rail alignment of a tram line according to the present invention includes a main fixing mechanism 1 and an auxiliary fixing mechanism 2 .
[0018] The main fixing mechanism 1 includes a main chuck 11 , a main branch frame 12 , a ratchet 13 , a wire wheel 14 and a hand wheel handle 15 . Wherein, the main chuck 11 is composed of left and right main chucks respectively clamped on opposite sides of one end of the grooved rail 3 to be detected, that is, a left main chuck 111 and a right main chuck 112 are included. The top of 111 extends upwards to form a main fixing block 113, and the top of the right main chuck 112 extends upwards to form a main locking block 114; the main fixing block 113 and the main locking block 114 are locked horizontally through the main fastening shaft 16 Fix, so that the main chuck 11 is locked and fixed on the grooved rail 3 to be detected; the tail end of the main fastening s...

The invention relates to a streetcar line groove rail profile detection device comprising main and assistant fixing mechanisms. The main fixing mechanism comprises a main clamp head, a main branch rack, a ratchet wheel, a wire wheel and a hand wheel handle. The main clamp head is composed of left and right main clamp head units respectively clamped to two opposite sides of one end of a to-be-detected groove rail, and the left and right main clamp head units are locked and fixed by a main fastening shaft. The wire wheel and the ratchet wheel are hinged to each other through a wire wheel shaft, and the wire wheel is wound with a PE fishing thread. One end of the wire wheel shaft stretches out of an outer side of the wire wheel, and an elastic collar is also installed between the wire wheel shaft and the wire wheel. The assistant fixing mechanism comprises an assistant clamp head, an assistant branch rack and a cord pull rod. The assistant clamp head is composed of left and right assistant clamp head units respectively clamped to two opposite sides of the other end of the to-be-detected groove rail, and the left and right assistant clamp head units are locked and fixed by an assistant fastening shaft. The streetcar line groove rail profile detection device can be used for in-plant assembly and test laying of a common line, and can also be used for adjustment before laying the line, thereby facilitating streetcar line rail profile detection.
Description
technical field [0001] The invention relates to the technical field of trams, in particular to a detection device for the line shape of a grooved rail of a tram line. Background technique [0002] In recent years, the construction of tram lines has developed rapidly. As an important part of the line infrastructure, the state of the track is related to whether the train can run safely. At present, the measuring and testing equipment of railway line rails include: total station, high-precision GPS and other precision surveying and mapping instruments, mobile turnout conversion equipment comprehensive testing vehicle, etc. These testing equipment are mainly used for the detection of the overall position of the line and the performance after the laying is completed. When the rails of the tram line are laid, they cannot be used for the detection and control of the line shape and laying quality. Contents of the invention [0003] In view of the above problems, the present inve...
