Description

Technical Field

[0001] This utility model relates to the fields of mechanical design and ergonomics, and in particular to a pantograph carbon slide plate thickness measuring device. Background Technology

[0002] In the operation and maintenance of rail transit vehicles, traditionally, vernier calipers are used to measure changes in the thickness of carbon fiber sliding plates. Specifically, measurements are taken at several to a dozen points on the carbon fiber sliding plate surface, depending on the specific specifications of each subway company. However, the calipers' limited range cannot completely cover the entire width of the carbon fiber sliding plate surface during measurement; they must be positioned at the edges of the plate and the thickness measured at points within the limited width, causing significant inconvenience. For example, patent application CN201922437790.0, entitled "Portable Automatic Carbon Fiber Sliding Plate Thickness Measuring Device," includes a height adjustment component, a measuring platform, a rolling bearing, and a laser detection component. The height adjustment component automatically adjusts the vertical distance between the measuring platform and the support frame. The rolling bearing is hinged to the measuring platform, and during measurement, it needs to be secured to the bottom of the aluminum support plate of the carbon fiber sliding plate to ensure the measuring platform is always aligned with the bottom of the support plate, thus greatly improving detection accuracy. However, in practical use, this solution has a complex structure, hindering rapid on-site implementation. Utility Model Content

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1

[0029] Based on the problems mentioned in the background art, this application proposes a pantograph carbon sliding plate thickness measuring device, the scheme of which includes: a clamp 1, a carrier 3, and a thickness gauge 4, which are assembled and used together, such as... Figures 1 to 2 As shown, this embodiment proposes a scheme in which a measurement section is opened on the left side of the clamp 1 to constrain the position when measuring the thickness of the pantograph carbon sliding plate. A track 2 and a strip hole 11 located in front of the track 2 are opened on the top of the clamp 1. A carrier 3 is fixedly installed at the sliding end of the track 2, and a limiting hole is opened at the end of the carrier 3 for elastically installing the thickness gauge 4. The elastic installation method can be referred to Figure 5 With the end design of the support member 3, when in use, the measuring end of the thickness gauge 4 passes through the strip hole 11 to measure the distance from it to the surface of the pantograph carbon slide plate and outputs the data.

[0030] Compared to traditional thickness gauges, this application can plot a continuous curved distance graph and convert it into a thickness curve graph along a straight line on the surface of the pantograph carbon sliding plate. Furthermore, this curve graph can be obtained using the horizontal plane where the pantograph carbon sliding plate surface is located, resulting in a continuous curve graph in both the horizontal transverse and vertical directions.

[0031] The specific usage involves placing the pantograph carbon slide plate within the measurement range and sliding it along the track 2. At this time, the measuring end of the thickness gauge 4 slides within the strip hole 11, thus obtaining the aforementioned thickness curve.

[0032] Therefore, in order to achieve relative fixation of the pantograph carbon slider, such as Figure 1 As shown, the clamp 1 is fitted with a slot 6 at the bottom end of the inner side of its measuring range. The shape of the slot 6 is adapted to the bottom of the pantograph carbon slide plate. That is, the slot 6 is locked onto the bottom of the pantograph carbon slide plate. Applying force to it can make the slot 6 press against the bottom of the pantograph carbon slide plate or slide without gap on the bottom of the pantograph carbon slide plate.

[0033] Furthermore, based on the above scheme, in order to perform measurement calibration, the slot 6 is provided with a countersunk hole for the detachable installation of the reset post 5, and the distance between the thickness gauge 4 and the reset post 5 is measured for calibration.

[0034] Meanwhile, the clamp 1 is an integrated mechanism, with a first section 12 on its left side for measuring the thickness of the pantograph carbon slide plate, and a second section 13 on its right side to reduce the overall weight.

[0035] Example 2

[0036] Based on Embodiment 1, this application describes a second scheme based on the mechanical displacement thickness gauge 4, such as... Figure 3 As shown, the thickness gauge 4 is a physical thickness gauge, including a housing, a displacement shaft 42, a sensor that converts the end displacement of the displacement shaft 42 into an electronic signal, and a pressing end 41 that elastically drives the displacement shaft 42 to move in a preset direction. The middle portion of the support member 3 has a support section 31, the upper surface of the support member 3 is an arc-shaped support part 32 for supporting the base of the thumb, and the top of the support section 31 is a continuously curved part 33 for accommodating the other fingers.

[0037] When in use, it can be operated with one hand. Press the pressing end 41 with your thumb to move the displacement shaft 42 so that the end of the displacement shaft 42 presses against or moves away from the measuring surface. At this time, the base of the thumb presses against the arc-shaped support part 32, and the other fingers press on the arc-shaped support part 32.

[0038] like Figure 5 As shown, the two sides of the support interval 31 are the first straight section 34 and the second straight section 35, respectively. The extensions of the two straight sections intersect to form a stable triangular interval 7.

[0039] like Figure 5 As shown, the extension of the second straight line lies within the support curve of the base of the thumb in the arc-shaped support section 32.

[0040] Example 3

[0041] Based on Embodiment 1 and Implementation 2, this application also modifies the clamp 1. The clamp 1 is a combined structure, including a first support part 14 and a second support part 15. The lower surface of the tail of the first support part 14 extends downward to form a first connecting part 16, and the upper surface of the tail of the second support part 15 extends upward to form a second connecting part 17. The first connecting part 16 is connected to the second connecting part 17 by an elastic element such as a coil spring. The purpose of this implementation is to increase the measurement range of the thickness gauge.

[0042] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
