Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically a digital display detection device for railway vehicle wheels. Background Technology

[0002] Railway vehicles are the means of transporting goods on railways. In a broader sense, railway vehicles refer to any vehicle that must run along dedicated tracks. They are used to transport passengers and goods. As railway vehicles age, their wheels wear down, necessitating periodic inspections of the wheel thickness using monitoring devices to determine the extent of wear.

[0003] Currently, the inspection of wheel flange thickness for railway vehicles is basically carried out at four symmetrical points. While the upper part and the left and right sides of the wheel are relatively easy to inspect, the lower part of the wheel requires the inspector to bend over. Since there are many wheels on railway vehicles, the overall workload is quite heavy, which can easily cause injury to the inspector's back and reduce the accuracy of the inspection. Therefore, it is necessary to design a digital display inspection device for railway vehicle wheels to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a digital display detection device for railway vehicle wheels. This solves the problem that in existing technologies, when detecting the wheel flange thickness of railway vehicles, the inspector needs to bend over to perform the inspection, which results in a relatively high workload, is prone to causing back injuries to the inspector, and leads to a reduction in detection accuracy.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a digital display detection device for railway vehicle wheels, including a caliper body, a handheld frame inserted into the outer wall of the caliper body, and the handheld frame being connected to the caliper body by a pair of bolts; a detector body slidably sleeved on the outer wall of the caliper body, and a digital display screen and a pair of buttons installed on the front end face of the detector body; a detection component installed on the outer wall of the detector body; and an adjustment mechanism and a drive mechanism installed on the outer wall of the handheld frame.

[0006] The detection component includes a slide plate fixed to the outer wall of the detector body, and the slide plate is slidably connected to the outer wall of the caliper body. A first detection caliper head is fixed to the top of the slide plate, and a second detection caliper head is fixed to the top of the caliper body.

[0007] Preferably, the adjustment mechanism includes a screw rotatably connected to the handheld frame, a sleeve threadedly connected to the outer wall of the screw, and a vertical plate slidably connected to the groove of the caliper body, and the vertical plate is fixedly connected to the sleeve.

[0008] Preferably, the drive mechanism includes a housing mounted on the outer wall of the handheld frame. Connecting blocks are fixed to both ends of the outer wall of the housing, and the connecting blocks are connected to the handheld frame by bolts. A base is fixed inside the housing, and a reducer is fixed on the base. The input shaft and output shaft of the reducer are respectively connected to a motor and a transmission assembly.

[0009] Preferably, the transmission assembly includes a first synchronous pulley fixedly connected to the outer wall of the reducer output shaft, a second synchronous pulley fixedly connected to the outer wall of the screw, and the second synchronous pulley is rotatably connected to the first synchronous pulley through a synchronous belt, and the outer wall of the synchronous belt is clearance-fitted with the inner wall of the opening of the housing.

[0010] Preferably, the front end face of the box is connected to a box plate by a number of bolts.

[0011] Preferably, a fastening pin is connected to the top of the detector body.

[0012] Beneficial effects

[0013] This utility model provides a digital display detection device for railway vehicle wheels, which has the following beneficial effects:

[0014] When it is necessary to measure the thickness of the top and left and right wheels of a railway vehicle, that is, when the measuring personnel do not need to bend over, they can directly hold the caliper body, put the second detection caliper head in contact with the wheel, push the detector body to slide on the caliper body, and the detector body will drive the first detection caliper head to move through the slide plate until the first detection caliper head and the second detection caliper head are in contact with the wheel, and then record the value on the digital display screen.

[0015] When measuring the thickness of the bottom wheel of a railway vehicle, which requires the measuring personnel to bend over, the handheld frame can be used directly. Because the handheld frame has a certain length, the inspector can easily align the second detection caliper with the wheel without bending over. Then, the motor is started, and the motor, in conjunction with the reducer, drives the first synchronous pulley to rotate. The first synchronous pulley, through the synchronous belt, drives the second synchronous pulley to rotate, which in turn drives the screw to rotate. The screw, in conjunction with the sleeve and the sliding groove of the caliper body, moves the vertical plate, causing the vertical plate to push the detector body to slide on the caliper body. The detector body, through the sliding plate, moves the first detection caliper until the first and second detection calipers are aligned with the wheel. The value is then recorded on the digital display screen. This method reduces the overall workload, preventing back injury to the inspector, while also ensuring measurement accuracy.

[0025] A vertical plate 6 is installed at the slide groove of the caliper body 1 to limit the vertical plate 6, so that the screw 4 can drive the vertical plate 6 to move through the sleeve 5.

[0026] In this embodiment, the driving mechanism is further configured such that the drive mechanism includes a housing 7 mounted on the outer wall of the handheld frame 2, and connecting blocks 15 are fixedly connected to the outer walls at both ends of the housing 7, and the connecting blocks 15 are connected to the handheld frame 2 by bolts.

The input shaft and output shaft of the reducer 9 are respectively connected to a motor 10 and a transmission assembly.

[0027] The controller for starting and stopping the motor 10 and the battery can be installed on the left outer wall of the handheld device 2 in a position that is easily accessible to the hand, so as to facilitate the control of the motor 10.

[0032] It is worth noting that the electrical structures and other components involved in this application can be selected according to the user's needs, as long as they meet the requirements of this application. At the same time, the corresponding control circuits and other components are all existing technologies, which can be fully implemented by those skilled in the art, so they will not be described in detail here.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: When it is necessary to measure the thickness of the top and left and right wheels of a railway vehicle, that is, when the measuring personnel do not need to bend over, they can directly hold the caliper body 1, put the second detection head 18 into contact with the wheel, push the detector body 3 to slide on the caliper body 1, and the detector body 3 drives the first detection head 17 to move through the slide plate 16 until the first detection head 17 cooperates with the second detection head 18 to fit into contact with the wheel, and then record the value on the digital display screen 19.

The detector body 3, through the sliding plate 16, moves the first detection caliper 17 until it engages with the second detection caliper 18 and is in contact with the wheel. The value on the digital display screen 19 is then recorded. This method reduces the overall workload and prevents back injury to the measuring personnel while ensuring measurement accuracy.
