Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of Gray bus position detection, and particularly relates to a Gray bus rigid inner container for accurately arranging a plurality of address lines (G lines) in a Gray code in the Gray bus. BACKGROUND

[0002] The Gray bus position detection technology adopts electromagnetic induction principle and Gray code principle for position detection, and is a continuous non-contact absolute position detection method. The Gray bus position detection technology detects the position of an induction antenna box in the length direction of a Gray bus through mutual induction between the induction antenna box installed on a mobile device and the Gray bus installed along the track direction. The Gray bus position detection technology has strong anti-electric interference capability, can work stably for a long time in a harsh environment, can be used for position detection of linear or ring displacement, is easy to install, has stable and reliable address, and has no recoding and error code phenomenon.

[0003] The positioning accuracy of the Gray bus position detection technology depends on the arrangement accuracy of the plurality of address lines in the Gray bus. The address lines need to be crossed once every certain step, and are arranged and bundled according to the Gray code rule. Currently, this work can only be completed manually, and there is no structure for accurately fixing the plurality of address lines, which makes it difficult to ensure the step length and thus affects the positioning accuracy. SUMMARY

[0004] The purpose of the present application is to overcome the shortcomings of the prior art, and to provide a Gray bus rigid inner container which has a simple structure and is easy to use, arranges the address lines in the Gray bus on the rigid inner container according to the Gray code rule, and can greatly improve the positioning accuracy of the Gray bus position detection technology.

[0005] The purpose of the present application is achieved by the following technical solution.

[0006] A Gray bus rigid inner container includes a base plate, a chain plate, and a rivet. The base plate is provided with fixing holes, the hole spacing of the fixing holes is the same as the crossing step length of the address lines of the Gray bus, the chain plate is provided with notches for fixing the address lines crossed by the step length, the notch width is slightly smaller than the cable diameter, the notch height is slightly larger than the diameter of four cables, four cables can be fixed vertically, the chain plate is provided with fixing holes, the fixing holes on the chain plate are aligned with the fixing holes on the base plate, and the chain plate can be fixed on the base plate through the rivet. Therefore, the chain plate position is the same as the crossing step length of the address lines of the Gray bus, and the chain plate is provided with horizontal wings on both sides.

[0007] In the above technical solution, the spacing between the wings of the two connected chain plates is 5 mm, which ensures that the chain plates will not touch when the rigid inner container is rolled up, so that the rigid inner container can be rolled up for storage and transportation. However, too large spacing is not conducive to bundling the cables during wiring, and the spacing should be reduced as much as possible.

[0008] In the above technical solution, the chain plate is provided with a binding post at both ends, so that the cable can be bundled and fixed.

[0009] In the above technical solution, the substrate is selected from a non-metal material with good rigidity and toughness.

[0010] In the above technical solution, the substrate is provided with a process hole, and the Gray busbar rigid liner is fixed on the braiding frame through the process hole, so as to prevent the rigid liner from moving and shaking during the braiding of the cable.

[0011] In the above technical solution, the fixing hole on the substrate is processed by a high-precision machine tool, and the position accuracy is high.

[0012] In the above technical solution, the bottom of the chain plate is provided with an inner recessed step, the step height is the same as the substrate thickness, and the width is slightly larger than the substrate width, so that the bottom surface of the chain plate and the bottom surface of the substrate are on the same plane after the chain plate is installed on the substrate.

[0013] In the above technical solution, the rivet is selected from a 2.4 diameter open type round head core-pulling rivet, which can tightly connect the substrate and the chain plate while reducing the influence on the strength of the substrate and the chain plate.

[0014] The Gray busbar rigid liner has simple structure and convenient use, arranges the internal address lines of the Gray busbar on the rigid liner according to the Gray coding rule, significantly improves the positioning accuracy of the Gray busbar position detection technology, and enables the Gray busbar position detection technology to be more widely applied.

Thus, the present application is not intended to be limited to the following disclosed embodiments, and changes can be made in the embodiments in accordance with the teachings of the present application without departing from the scope and spirit of the application.

[0022] It is to be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can also be present.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0024] The embodiment provides a grey bus rigid inner container, which comprises a base plate 1, a chain plate 2 and a rivet 3.

[0025] As shown in Figure 1 The base plate 1 is made of a non-metal material with good rigidity and toughness. The non-metal material can avoid interference with signals. The good rigidity enables the base plate to maintain the machining precision after processing. The good toughness enables the rigid inner container to be rolled into a roll, which is convenient for storage and transportation. In the embodiment, the base plate 1 is made of an epoxy resin plate. The base plate 1 is processed with fixing holes 1.1. The hole spacing of the fixing holes 1.1 is the same as the address line crossing step length of the grey bus. The base plate is processed with process holes 1.2. The grey bus rigid inner container is fixed on a cable rack through the process holes 1.2. When the cable is arranged, the rigid inner container can be prevented from being displaced and shaken. The holes on the base plate 1 are all processed by a high-precision machine tool, and the position accuracy is high.

[0026] As shown in Figure 2 , Figure 3 , Figure 4As shown, the chain plate 2 is made of non-metallic material, which can avoid interference with signals. The mold making can ensure the size accuracy and stability of the chain plate, and the production speed is fast and the cost is low. The chain plate 2 is provided with a notch 2.2 for fixing the address lines crossed by steps. The width of the notch 2.2 is slightly smaller than the diameter of the cable, so that the cable can be easily put into the notch 2.2 and is not easy to fall out. The height of the notch 2.2 is slightly larger than the diameter of four cables, so that the four cables can be vertically fixed. The vertically arranged cables crossed by steps can unify the step length of each pair of address lines and improve the accuracy. The chain plate 2 is provided with a fixing hole. By aligning the fixing hole on the chain plate with the fixing hole on the substrate, the chain plate 2 can be accurately and firmly fixed on the substrate 1 by a rivet 3. Therefore, the position of the chain plate is the same as the step length of the address lines of the thunder bus. The chain plate is provided with a wire binding column 2.4 at both ends, which can be easily fixed by a binding rope. The chain plate is provided with an inner recess step 2.1 at the bottom, and the height of the step is the same as the thickness of the substrate. The width of the step is slightly larger than the width of the substrate 1. After the chain plate 2 is installed on the substrate 1, the bottom surface of the chain plate and the bottom surface of the substrate are on the same plane. The chain plate is provided with a horizontal wing plate 2.5 at both sides, and the distance between the wing plates of two adjacent chain plates is 5mm. The horizontal wing plate 2.5 makes the upper surface of the rigid liner flat, so that the internal part is flat during rubber packaging and does not collapse.

[0027] In this embodiment, the rivet is selected to have a diameter of 2.4 and an open type round head core-pulling rivet, which can tightly connect the substrate and the chain plate while reducing the influence on the strength of the substrate and the chain plate.

[0028] When making the Gray bus rigid liner, the substrate is first cut to the required length, the fixing hole is processed on the substrate using a high-precision machine tool, and then the chain plate is fixed on the substrate using a rivet. Since all connection positions are determined by high-precision positioning holes, the Gray bus rigid liner has high precision. The Gray bus rigid liner also has good flexibility, can be rolled into a roll, and is convenient for transportation and storage. At the same time, the structure is simple, the cable is easy to make and arrange, and the cost is low.

[0029] As shown in Figure 5 When arranging the internal cables of the Gray bus, the cables are only arranged on the Gray bus rigid liner according to Gray coding, which can ensure the arrangement accuracy of the internal cables of the Gray bus, thereby improving the accuracy of the Gray bus position detection technology. The cable arranged by using the high-precision Gray bus rigid liner can be packaged by rubber to form a high-precision Gray bus.

[0031] Those skilled in the art can easily understand that the above description is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
