DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Please refer to Figures 1-9 The utility model provides a height measurement frock, be applicable to rail vehicle field, concretely is a kind of bogie current collector height measurement frock, place in the carbon slide plate 11 of current collector 1 upper end, including:

[0031] Measuring plate 21 is placed on carbon slide plate 11;

[0032] Measuring scale 22 is inserted in measuring plate 21 and is vertically arranged with measuring plate 21;

[0033] Installation slot 2101 for placing measuring scale 22 is formed in measuring plate 21;

[0034] The lower end of measuring scale 22 is abutted on the support 12 on current collector 1.

[0035] It should be noted that during the measurement of the installation height of the current collector 1, the installation height of the carbon slide plate 11 on the current collector 1 can be measured by the measuring device 2, so as to measure the installation height of the current collector 1. The measuring plate 21 is placed horizontally on the upper end of the carbon slide plate 11, and then the measuring ruler 22 is placed vertically on the support 12. Then the measuring plate 21 is moved to one side of the measuring ruler 22, and the measuring ruler 22 is clamped in the installation slot 2101 formed in the measuring plate 21. By observing the position where the upper end of the installation slot 2101 contacts the measuring ruler 22 and subtracting the height of the measuring plate 21 itself, the installation height of the carbon slide plate 11 can be measured. The vertical arrangement of the measuring plate 21 and the measuring ruler 22, and the design that the lower end of the measuring ruler 22 abuts against the support 12 of the current collector 1, ensure that the measuring ruler 22 can accurately reflect the height of the current collector 1, greatly improving the measurement accuracy.

[0036] In an embodiment, the lower end of the measuring plate 21 is provided with a supporting mechanism 23 for supporting the measuring ruler 22 at a position below the installation slot 2101. The supporting mechanism 23 includes a mounting block 231 fixed to the lower end of the measuring plate 21, a rotating block 232 arranged on the mounting block 231, and a fixing ring 233 arranged on the side of the rotating block 232 away from the mounting block 231. The fixing ring 233 is provided with an insertion slot 23301 for placing the measuring ruler 22.

[0037] In this way, referring to Figure 9 , the supporting mechanism 23 provides stable and reliable support for the measuring ruler 22 through the cooperation of the mounting block 231, the rotating block 232 and the fixing ring 233. When measuring the installation height of the carbon slide plate 11, the installation angle of the fixing ring 233 on the mounting block 231 is adjusted so that the fixing ring 233 is arranged in parallel with the measuring plate 21. This design effectively prevents the measuring ruler 22 from shaking or deviating due to external forces during measurement, thereby ensuring the accuracy and stability of the measurement results. Since the measuring ruler 22 is slidably arranged in the insertion slot 23301 of the fixing ring 233, its position is limited, which helps to reduce the measurement error caused by the movement of the measuring ruler 22.

[0038] In an embodiment, a fixing mechanism 24 is arranged on the side of the lower end of the measuring plate 21 away from the installation slot 2101 for fixing the measuring ruler 22.

[0039] In this way, referring to Figure 8When the setting is finished, the fixed ring 233 is rotated on the installation block 231 to change the installation angle, then the measuring scale 22 is moved below the measuring plate 21, then the lower end of the measuring scale 22 is fixed by the fixing mechanism 24, so that the measuring scale 22 is fixed on the lower end of the measuring plate 21, the measuring scale 22 can be stored, and the phenomenon that the measuring scale 22 is lost when not in use can be prevented.

[0040] In an embodiment, the fixing mechanism 24 comprises a fixed frame 241 fixed on the lower end of the measuring plate 21, a screw rod 242 arranged on the upper end of the fixed frame 241, a clamping plate 245 arranged on the lower end of the fixed frame 241, and a connecting piece 244 arranged on the lower end of the screw rod 242 and connected with the clamping plate 245, the connecting piece 244 is arranged on the fixed frame 241, and the clamping plate 245 is symmetrically arranged relative to the screw rod 242.

[0041] In this way, as shown in Figures 4-8 , the connecting piece 244 is driven to move by the screw rod 242, so that the clamping plate 245 moves on the lower end of the fixed frame 241 to approach or move away from each other, and the measuring scale 22 is clamped and fixed.

[0042] In an embodiment, the connecting piece 244 comprises a rack 2441 rotatably arranged on the lower end of the screw rod 242, an installation shaft 2412 arranged on the fixed frame 241, a gear 2442 sleeved on the installation shaft 2412, and a rotating rod 2443 arranged on the side of the gear 2442 away from the rack 2441, and the rotating rod 2443 is connected with the clamping plate 245.

[0043] In this way, as shown in Figure 7 , the connecting piece 244 is driven by the meshing transmission of the rack 2441 and the gear 2442, so that the accurate conversion from the rotating movement of the screw rod 242 to the clamping movement of the clamping plate 245 is realized. This design ensures that the measuring scale 22 can be stably fixed on the lower end of the measuring plate 21 by a stable and controllable clamping force during the fixing process.

[0044] In an embodiment, a stabilizing rod 2444 is arranged between the clamping plate 245 and the fixed frame 241, a connecting plate 2411 is arranged between the fixed frame 241 and the measuring plate 21, and the upper end of the screw rod 242 is provided with a rotating disc 243.

[0045] In this way, as shown in Figures 6-8 , the stabilizing rod 2444 is arranged between the clamping plate 245 and the fixed frame 241, which effectively enhances the stability of the clamping plate 245 when clamping the measuring scale 22, prevents deformation or displacement of the clamping plate 245 due to uneven force, and thus ensures the stability of the fixing of the measuring scale 22.
