Abstract
Description
Technical Field
[0001] This utility model relates to the field of spacer detection technology, and in particular to a rapid detection device for spacers in a simulated assembly state. Background Technology
[0002] Railway tracks are a key infrastructure of railway systems. Among the many components of railway tracks, track gauge, track gaps, and track orientation are the core indicators for measuring the geometric state of the track.
[0003] Traditional methods often rely on manual operation using simple measuring tools. However, the manual operation process is extremely cumbersome, requiring a series of steps such as calibration and positioning. When using these tools, workers rely too much on operating skills, otherwise it is easy to make mistakes in operation, which will affect the accuracy of the measurement results.
[0004] Therefore, this utility model provides a rapid detection device for spacer irons in simulated assembly conditions. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a rapid detection device for spacer irons in simulated assembly conditions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid detection device for spacer irons in a simulated assembly state, comprising a side stand and a measuring component. The measuring component includes a guide rail fixedly connected to the inner side of the side stand, a slider slidably connected to the outer side of the guide rail, a tension spring fixedly connected to the outer side of the slider, an inclined abutment block fixedly attached to the bottom end of the slider, and a spacing adjustment component fixedly connected to the outer side of the measuring component.
[0007] In a preferred embodiment, the spacing adjustment assembly includes a connecting block fixedly connected to the top of the slider, a sliding column slidably connected inside the connecting block, and a bidirectional lead screw threadedly connected inside the sliding column.
[0008] In a preferred embodiment, the end of the tension spring away from the slider is fixedly connected to the side block, and a scale plate is fixedly connected to the top of the side block.
[0009] In a preferred embodiment, the top of the slider is slidably connected to a scale plate, and a pointer is fixedly connected to the top of the slider.
[0010] In a preferred embodiment, a limiting block is fixedly connected inside the connecting block, and a sliding groove is provided inside the bottom end of the slider and it is slidably connected to the guide rail through the sliding groove.
[0011] In a preferred embodiment, a groove is provided on the outer side of the sliding column, and the limiting block is slidably connected to the groove.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. The thrust generated by the inclined block in contact with the spacer iron drives the slider to slide along the guide rail, and then the elastic deformation of the tension spring is converted into the linear displacement of the pointer on the scale plate. This design, by switching the compressive force to a linear displacement, allows the operator to directly read the dimensional deviation from the scale value without complicated calculations. It solves the problems of traditional manual measurement that rely on operational skills and involve cumbersome procedures.
[0014] 2. By rotating the bidirectional lead screw, the sliding column moves linearly within the groove. Then, the movement trajectory of the sliding column is constrained by the limit block, thereby achieving overall position adjustment of the slider. This design utilizes the cooperation of the bidirectional lead screw and the sliding column to achieve precise spacing adjustment, adapt to different assembly requirements, and effectively solve the problems of non-standard operation and inaccurate measurement in traditional methods.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a rapid detection device for spacer iron in a simulated assembly state, including a side block 1 and a measuring component 2. The measuring component 2 includes a guide rail 21 fixedly connected to the inner side of the side block 1, a slider 22 slidably connected to the outer side of the guide rail 21, a tension spring 23 fixedly connected to the outer side of the slider 22, a pointer 24 fixedly connected to the top of the slider 22, a scale plate 25 fixedly connected to the top of the side block 1, the top of the slider 22 slidably connected to the scale plate 25, the end of the tension spring 23 away from the slider 22 fixedly connected to the side block 1, and an inclined abutment 26 fixedly attached to the bottom of the slider 22.
[0026] The side support block 1 serves as the basic support structure for the entire testing equipment, providing a stable mounting platform for the measuring component 2. This ensures that the measuring component 2 can be accurately fixed in the appropriate position, keeping the equipment stable during testing. The guide rail 21 provides a linear track for the slider 22. The guide rail 21 allows the slider 22 to slide along a predetermined straight path inside the side support block 1, restricting the direction of movement of the slider 22 and ensuring the straightness of the measurement process, thereby improving measurement accuracy. The slider 22 works with the guide rail 21 to achieve the sliding function. On the other hand, as a key component connecting the tension spring 23 and the pointer 24, it transmits the elastic force of the tension spring 23 to the pointer 24 and drives the pointer 24 to move through its own sliding. The tension spring 23 provides elastic tension. When the slider 22 moves due to contact with the spacer, the tension spring 23 is stretched, and the resulting elastic force balances the force exerted by the measured object on the slider 22. Elastic deformation can convert the dimensional changes of the measured object into measurable force changes. The pointer 24, as an indicating component, moves with the slider 22 and indicates the corresponding scale value on the scale plate 25. The displacement of the pointer 24 directly reflects the positional change of the slider 22. The scale plate 25 provides a scale reference for the pointer 24. The scale plate 25 has uniformly distributed scale lines, each scale line representing a certain length unit or size range. The scale value pointed to by the pointer 24 can directly reflect the dimensional parameters of the measured object (spacer), such as thickness and height, and the degree of deviation from the standard assembly state. The inclined block 26 contacts the spacer, and its inclined surface can better adapt to the shape of the spacer and increase the contact area with the measured object. When the slider 22 moves, the inclined block 26 can effectively convert the dimensional changes of the measured object into linear motion of the slider 22, thereby driving the pointer 24 to indicate the corresponding scale on the scale plate 25.
[0027] A spacing adjustment component 3 is fixedly connected to the outside of the measuring component 2. The spacing adjustment component 3 includes a connecting block 31 fixedly connected to the top of the slider 22. A sliding column 34 is slidably connected inside the connecting block 31. A two-way lead screw 32 is threaded inside the sliding column 34. A limit block 33 is fixedly connected inside the connecting block 31. A groove 35 is opened on the outside of the sliding column 34. The limit block 33 is slidably connected to the groove 35.
[0028] The connecting block 31 serves as the mounting base for the spacing adjustment assembly 3, connecting other components such as the sliding column 34. It is also fixed to the top of the slider 22, making the spacing adjustment assembly 3 and the measuring assembly 2 a single unit. This provides a platform for the installation and support of the bidirectional lead screw 32 and the sliding column 34, ensuring the relative positional relationship between the components. The sliding column 34 is threadedly connected to the bidirectional lead screw 32. Rotating the bidirectional lead screw 32 causes the sliding column 34 to slide along the groove 35 of the connecting block 31. Simultaneously, it cooperates with the limiting block 33 to restrict the direction of movement of the sliding column 34, ensuring it can only move along a predetermined straight path. This converts the rotational motion of the bidirectional lead screw 32 into its own linear motion, thereby achieving spacing adjustment. The bidirectional lead screw 32 can be rotated to change the threaded connection with it. The position of the sliding column 34, the thread direction and pitch of the bidirectional lead screw 32 determine the moving speed and adjustment accuracy of the sliding column 34. Its rotational motion is converted into linear motion of the sliding column 34, thereby changing the spacing between the components connected to the sliding column 34. The limiting block 33 cooperates with the slide groove 35 of the sliding column 34 to restrict the movement direction of the sliding column 34, ensuring that the sliding column 34 can only move along the linear direction of the slide groove 35, preventing the sliding column 34 from lateral deviation or shaking during movement, and providing guidance and limiting functions for the linear movement of the sliding column 34. The slide groove 35 is opened on the outside of the sliding column 34 and cooperates with the limiting block 33 to provide guidance and limiting space for the linear movement of the sliding column 34. The shape and size of the slide groove 35 determine the movement trajectory and adjustable range of the sliding column 34.
[0029] Working principle:
[0030] like Figure 1 - Figure 5 As shown:
[0031] In use: When the spacer contacts the inclined abutment 26, the inclined abutment 26 is subjected to the force of the spacer. This force causes the slider 22 to move on the guide rail 21 against the elastic force of the tension spring 23. The movement of the slider 22 causes the pointer 24 at its top to slide along a straight path on the scale plate 25, thus making the pointer 24 point to the corresponding scale value. This scale value can directly reflect the degree of deviation between the dimensional parameters of the spacer and the standard assembly state, providing the operator with intuitive measurement results and realizing the function of rapid detection of the assembly state of the spacer. When the spacing needs to be adjusted, the operator can rotate the bidirectional lead screw 32, which drives the sliding column 34 threaded to it to slide along the slide groove 35 of the connecting block 31. The movement of the sliding column 34 changes the spacing between the components connected to it, thereby achieving precise adjustment of the spacing to meet the inspection requirements under different assembly conditions. During this process, the limiting block 33 and the slide groove 35 cooperate with each other to restrict the movement direction of the sliding column 34 and provide a certain sliding space to prevent the tilting block 26 from jamming with the bidirectional lead screw 32 when it contacts the spacer, thus preventing it from moving.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
