[0002] In high-speed railways, catenary is the main power supply equipment, and electric locomotives obtain electric energy through catenary. To ensure good contact between the pantograph and the contact wire and reliable current collection, and to guarantee the safe operation of high-speed railways, a series of testing work must be carried out in addition to certain requirements for the design, construction and operation of contact wire suspension. The rapid measuring scale for geometric parameters of pantograph-catenary is a special tool for measuring the geometric parameters between the pantograph and catenary in electrified railways, and is of great significance for ensuring the safe operation of the pantograph-catenary system.

[0003] However, the existing pantograph-catenary measuring scale has a small measuring range when in use, and it takes a lot of time, labor and effort to complete the entire pantograph-catenary measurement. Content of the utility model

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a rapid measuring scale for geometric parameters of pantograph-catenary, comprising a mounting frame and a measuring assembly. A pantograph-catenary measuring instrument is mounted in the middle of the top of the mounting frame, and a receiving groove is opened on the surface of the mounting frame. The measuring assembly for segmented rapid measurement is arranged inside the receiving groove, and the measuring assembly comprises a moving rod, a limit rod, a moving block, a connecting rod, a panel and a handle. The limit rod is arranged inside the moving rod, the moving block is mounted outside the limit rod, the side of the moving block is movably connected with the connecting rod, the panel is arranged at the right end of the connecting rod, and the handle is mounted on the surface of the panel.

[0006] Further, the mounting frame and the receiving groove are of an integrated structure, and two groups of the receiving groove and the measuring assembly are provided.

[0007] Further, the limit rod and the moving block are in socket sliding connection, and the moving block and the connecting rod are in rotational connection.

[0008] Further, an electric push rod is mounted in the middle of the lower end of the mounting frame, and the mounting frame is H-shaped.

[0009] Further, a limit frame is mounted outside the mounting frame, and the limit frame is C-shaped (in Chinese character 匚 shape).

[0010] Further, a base is mounted at the lower end of the limit frame, and the limit frame and the base are fixedly connected.

[0011] Furthermore, the top of the movable rod is provided with an auxiliary component for auxiliary measurement, and the number of auxiliary components is the same as the number of movable rods.

[0012] Furthermore, the auxiliary component includes a mounting hole and a scale rod, and the scale rod is engaged inside the mounting hole.

[0013] This invention provides a rapid measurement scale for bow and catenary geometry parameters, which has the following advantages: 1. This utility model uses multiple moving rods to unfold horizontally and move out of the storage slot. The moving rods are equidistantly distributed under the connection of the X-shaped connecting rods. The moving rods and auxiliary components are equidistantly distributed below the contact wire, which can quickly complete the detection of the contact wire and make the non-smooth position exposed in time. The limiting rod is used to guide the moving block and connecting rod during deformation adjustment.

[0014] 2. This utility model uses an electric push rod to control the height adjustment of the mounting frame and the pantograph catenary measuring instrument. The pantograph catenary measuring instrument can be rotated and adjusted at the top of the mounting frame as needed. The limiting frame provides directional movement space for the mounting frame. The mounting hole is used for quick insertion of the scale rod, which helps the pantograph catenary measuring instrument to quickly detect the smoothness of the contact wire.

A contact wire measuring instrument 2 is mounted on the top center of the mounting frame 1. The measuring instrument 2 can be rotated and adjusted at the top of the mounting frame 1 as needed. The measuring instrument 2 has a built-in Class 2 red laser for quickly locating the reference points for measuring contact wire guide height and pull-out value. The position of the light spot can be clearly identified during the day, avoiding measurement deviations. The surface of the mounting frame 1 has a storage slot 3, and the mounting frame 1 and storage slot 3 are an integrated structure. The measuring component 4 for rapid segmented measurement is located inside the storage slot 3. Two sets of storage slots 3 and measuring components 4 are provided. The measuring component 4 includes a moving rod 401, a limiting rod 402, a moving block 403, a connecting rod 404, a panel 405, and a handle 406. The moving rod 401... An internal limit rod 402 is provided, and multiple movable rods 401 are horizontally unfolded and moved out of the storage slot 3. The movable rods 401 are equidistantly distributed under the connection of the X-shaped connecting rod 404. The movable rods 401 and the auxiliary component 8 are equidistantly distributed below the contact wire, which can quickly complete the detection of the contact wire and make the non-smooth position appear in time. A movable block 403 is installed on the outside of the limit rod 402. The connecting rod 404 is movably connected to the side of the movable block 403. The limit rod 402 plays a directional guiding role for the movable block 403 and the connecting rod 404 during deformation adjustment. A panel 405 is provided on the right end of the connecting rod 404. A handle 406 is installed on the surface of the panel 405. The limit rod 402 and the movable block 403 are connected by a sleeve sliding connection, and the movable block 403 and the connecting rod 404 are connected by a rotation.

[0019] like Figure 2 As shown, the top of the moving rod 401 is provided with an auxiliary component 8 for auxiliary measurement, and the number of auxiliary components 8 is the same as that of the moving rod 401. The auxiliary component 8 includes a mounting hole 801 and a scale rod 802, and the scale rod 802 is installed inside the mounting hole 801. The mounting hole 801 is used for quick insertion of the scale rod 802, which assists the pantograph-catenary measuring instrument 2 in quickly detecting the smoothness of the contact wire.

[0020] like Figure 3 As shown, an electric push rod 5 is installed in the middle of the lower end of the mounting frame 1.

Figures 1-4The structure shown allows users to climb onto the roof of the vehicle and fix the base 7 thereon. The electric push rod 5 extends, adjusting the height of the mounting bracket 1 and the catenary measuring instrument 2 to the desired position. The catenary measuring instrument 2 can be rotated and adjusted at the top of the mounting bracket 1 as needed. Pulling the handle 406 and panel 405 causes multiple moving rods 401 to unfold laterally and move out of the storage slot 3. The moving rods 401 are evenly distributed under the connection of the X-shaped connecting rods 404. The scale rods 802 are sequentially inserted into the mounting holes 801, ensuring the moving rods 401 and auxiliary components 8 are evenly distributed below the contact wire. The catenary measuring instrument 2 uses a built-in Class 2 red laser to quickly locate the reference point for measuring the contact wire guide height and pull-out value. During the day, the laser spot position can be clearly identified, avoiding measurement deviations. The scale rods 802 assist the catenary measuring instrument 2 in quickly detecting the smoothness of the contact wire, thus rapidly completing the contact wire inspection and promptly revealing any irregularities.
