[0002] The subway electric passenger car coupler is a key component for connecting cars. Its height must be accurately matched to ensure that the connection between cars and between cars and locomotives is firm and reliable. By detecting the height of the coupler, the connection between cars can be ensured to be safe, and the separation or loosening between cars can be avoided, thus ensuring the safety of the train during travel. At present, the height of the coupler is mainly measured manually. The specific operation is: a handheld measuring ruler is placed on the horizontal rail surface and perpendicular to the rail plane, and the height value of the center line of the coupler is read by naked eyes. It is not convenient to use the measuring ruler in a small space. For example, the measuring ruler cannot be conveniently positioned, aligned and read. The above measurement method has the problems of low measurement accuracy and low efficiency, and requires high professional skills of the operator. After the operation, there is still a situation where the coupler height is inconsistent, resulting in the coupler not being able to be successfully connected. Therefore, it is necessary to design a tooling that is convenient for measuring the height of the coupler. Summary of the invention

Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0020] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0022] A measuring device for locomotive coupler height and vehicle body height, such as Figure 1 and Figure 2 As shown, it includes a positioning seat 1, an auxiliary frame 2, a support frame 3 and a height gauge 4; the positioning seat has a mounting groove 5 on the upper surface, and a limit structure matching the track on the lower surface, and the base 14 of the height gauge is installed in the mounting groove. Usually, one end of the mounting groove can be notched to facilitate the installation of the base of the height gauge.
[0023] The support frame is arranged on one side of the positioning seat, the upper surface of the positioning seat and the upper surface of the support frame are in the same plane, or the two are parallel, and the auxiliary frame is perpendicular to the surface of the positioning seat, so that when the support frame is adjusted to a horizontal state, the upper surface of the positioning seat is horizontal, that is, the height gauge and the auxiliary frame are both in a vertical state, ensuring accurate measurement results. A level 6 is installed on the support frame, and a leveling mechanism is provided at one end of the support frame away from the positioning seat. Preferably, the level is embedded in the upper surface of the support frame.
[0024] The auxiliary frame is vertically arranged above the positioning seat. A vertical sliding groove 8 is provided on the auxiliary frame. An auxiliary measuring arm 9 is slidably installed in the sliding groove. The auxiliary measuring arm extends towards the side away from the support frame. The lower surface of the measuring claw 15 of the height gauge abuts against the upper surface of the auxiliary measuring arm. The auxiliary measuring arm is perpendicular to the auxiliary frame. One end thereof is provided with a fitting portion 10, and the other end is provided with a measuring head 11. The fitting portion is slidably matched with the sliding groove on the auxiliary frame, and the lower surface of the measuring claw of the height gauge abuts against the upper surface of the fitting portion. The auxiliary measuring arm is used as an extended structure of the measuring claw, so as to realize the measurement of the coupler height or the car body height.
[0025] As an example, the fitting portion is in the shape of "I", or "F", or "U". A limiting groove for cooperating with the side wall of the sliding groove is provided on the fitting portion, ensuring that when the auxiliary measuring arm slides up and down, it can always be perpendicular to the auxiliary frame, laying a foundation for the accuracy of the measurement result.
[0026] The upper surface of the measuring head is lower than the upper surface of the auxiliary measuring arm. In an optional embodiment, preferably, the distance from the upper surface of the measuring head to the upper surface of the auxiliary measuring arm is equal to the distance from the upper surface of the height gauge base to the lower surface of the positioning seat. Before applying the coupler height measurement, first place the positioning seat on the track so that the limiting structure clamps the track, and then appropriately adjust the leveling mechanism to keep the positioning seat horizontal, so that the height gauge is in a vertical state to ensure the accuracy of the measurement structure.
[0027] When measuring the coupler height, slide the auxiliary measuring arm upward from bottom to top. When the measuring head of the auxiliary measuring arm abuts against the lower edge of the coupler upward, the value measured by the height gauge is the height value of the coupler, and no numerical conversion is required. When measuring the car body height, the operation method is the same as the above method for measuring the coupler height. When the measuring head abuts against the bottom of the car, the read value is the car body height. It should be noted that during measurement, only the auxiliary measuring arm needs to be extended into the position where the coupler is located or the lower edge of the car body bottom, without placing the measuring ruler in a narrow space. Coupled with the fact that the height gauge uses a digital display height gauge, such a structural design ensures that the value can be conveniently and intuitively read during the measurement operation, effectively improving the work efficiency.
[0028] The leveling mechanism includes an adjusting screw 7 vertically screwed on the support frame. The lower end of the adjusting screw extends out of the support frame. By screwing the adjusting screw, the support frame can be conveniently adjusted to be horizontal by observing the level, so as to ensure that the height gauge is in an upright state. The limiting structure includes two limiting plates 12 arranged parallel to the lower surface of the positioning seat. A limiting groove 13 for cooperating with the track is formed between the two limiting plates. The positioning seat is stably matched with the rail, and the height gauge will not shake during measurement.
[0029] The invention has a reasonable structural design. The positioning seat can be conveniently installed on the track and clamped on the track by a limiting structure. The stability of the positioning seat is guaranteed. The positioning seat is leveled by adjusting the leveling mechanism on the support frame, ensuring that the height gauge is always in an upright state during the measurement process, thereby ensuring that the measurement result is accurate. The height gauge reading is convenient and intuitive, and can be used to measure the height of the coupler and the height of the vehicle body, with high operating efficiency.
[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
