DETAILED DESCRIPTION

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0023] according to Figure 1-Figure 6 As described above, this embodiment proposes a bridge crane trolley wheel wear detection device, including a left clamping frame 1 and a right clamping frame 2, such as Figure 2 As described, the left clamping frame 1 and the right clamping frame 2 are of the same size, and the cross-sections of the left clamping frame 1 and the right clamping frame 2 are both L-shaped. Therefore, when the device is working, the distance between the left clamping frame 1 and the right clamping frame 2 is adjusted to achieve the effect of connecting with the wheel bracket of the bridge crane trolley. At the same time, it can adapt to the installation of wheel brackets of bridge crane trolleys of different widths, thereby improving the practicality of the device and facilitating disassembly and installation.

[0024] like Figure 1 and Figure 2As shown, a socket 3 is provided on the inner side of the left clamping frame 1, and a plug board 4 is installed on the right clamping frame 2. The plug board 4 is adapted to the socket 3 and connected to the left clamping frame 1 through a limiting component. The end of the socket 3 close to the plug board 4 is connected to the outside world, and then the plug board 4 can be inserted into the socket 3, and the socket 3 plays a role in positioning and limiting the plug board 4, so as to ensure that the left clamping frame 1 and the right clamping frame 2 can be in a horizontal state after clamping, and ensure the stability of the device, wherein the limiting component includes a fixing column 10, and the fixing column 10 is connected to the plug board 4. A plug hole is provided on the plug board 4, and the fixing column 10 passes through the plug hole, that is, the fixing column 10 is not fixedly connected to the plug board 4. Furthermore, both upper and lower sides of the fixing column 10 are provided with limit openings 11 on the left clamping frame 1, and the limit opening 11 has a certain length. At the same time, both ends (upper and lower ends) of the fixing column 10 pass through the limit opening 11, and are threadedly installed with a first fastening ring 12. When the first fastening rings 12 at the upper and lower ends of the fixing column 10 are tightened, their end faces are in contact with the left clamping frame 1 and the right clamping frame 2 at the corresponding positions, thereby utilizing the clamping force and friction force generated to achieve a fixing effect, and the length of the limit opening 11 is the adjustable range between the left clamping frame 1 and the right clamping frame 2. In this embodiment, the outer ring diameter of the first fastening ring 12 is greater than the width of the limit opening 11.

[0025] The left clamping frame 1 and the right clamping frame 2 are both equipped with a connecting plate 5 through a fine-tuning assembly. Figure 3 and Figure 4 As shown, the fine-tuning assembly includes a mounting cavity 13, that is, a mounting cavity 13 is provided on the left clamping frame 1 and the right clamping frame 2, one end of the mounting cavity 13 is communicated with the connecting plate 5, and a limiting column 14 is installed on the inner side of the mounting cavity 13, and the corresponding limiting column 14 is fixedly connected to the left clamping frame 1 and the right clamping frame 2 at the corresponding position, and a connecting block 15 is installed on the limiting column 14, and the connecting block 15 slides on the limiting column 14, and further the connecting block 15 is connected to the connecting plate 5, thereby, under the action of the connecting block 15 and the limiting column 14, the position of the connecting plate 5 can be adjusted. It can be adjusted within a certain range, and when the position of the connecting plate 5 is adjusted, the position of the subsequent auxiliary wheel 8 is also adjusted, and the connecting plate 5 with fine-tunable position is used to make the auxiliary wheel 8 adapt to the position of the bridge crane trolley wheel track. In this way, the device contacts the bridge crane trolley wheel track through the auxiliary wheel 8, and then uses the left clamping frame 1 and the right clamping frame 2 to clamp and fix the bridge crane trolley wheel bracket, so that the device has better stability when detecting the wear of the bridge crane trolley wheel, thereby improving the accuracy of wear detection.

[0026] The further connecting plate 5 is fixedly connected to the left clamping frame 1 and the right clamping frame 2 at the corresponding positions by bolts. When the connecting plate 5 is adjusted in position, the bolts need to be unscrewed. After adjusting the position, the bolts can be screwed on again. In the device, threaded connection holes 21 are provided on the connecting plate 5, and several groups of threaded connection holes 21 are evenly arranged. In this embodiment, a total of ten groups of threaded connection holes 21 are provided.

[0027] A connecting rod 6 is hinged on the connecting plate 5, a limiting frame 7 is hinged on the connecting rod 6, an auxiliary wheel 8 is installed at the lower end of the limiting frame 7, and an infrared rangefinder 9 is installed on the limiting frame 7. Then, through the arrangement of the connecting rod 6 and the connection by hinge parts, the device can adapt to the installation height within a certain range. That is, in the vertical direction, the distance between the auxiliary wheel 8 and the connecting plate 5 can be adjusted to adapt to different installation height requirements. Then, a signal transmitter is installed on the infrared rangefinder 9, and the signal transmitter is electrically connected to the infrared rangefinder 9. The signal transmitter is responsible for transmitting the signal of the infrared rangefinder 9. Then, when the device is working, there will be a corresponding signal receiver responsible for receiving the signal sent by the signal transmitter. When working, the detection end of the infrared rangefinder 9 faces the wheels of the overhead crane trolley. Then, distance measurement operations are carried out by means of infrared rays. When the surface of the wheels of the overhead crane trolley is worn, the distance measurement data of the infrared rangefinder 9 will fluctuate. Thus, it is convenient for the staff to preliminarily judge the wear amount of the wheels of the overhead crane trolley. This device is provided with an infrared rangefinder 9 on both sides of the wheels of the overhead crane trolley to detect the wear amount of a group of wheels at the same time, improving the detection effect.

[0028] Specifically, both ends (upper and lower ends) of the connecting rod 6 are respectively hinged with a first hinge part 16 and a second hinge part 17. Among them, the first hinge part 16 is connected to the connecting plate 5, and the second hinge part 17 is connected to the limiting frame 7. In this embodiment, the cross-section of the limiting frame 7 is in a U shape. Correspondingly, connection holes 18 are provided on both the first hinge part 16 and the second hinge part 17. In this embodiment, each group of hinge parts (the first hinge part 16 and the second hinge part 17) is provided with two groups of symmetrically arranged connection holes 18. And there is a connection port on the hinge part for connecting with the end of the connecting rod 6. Then, a limiting block 19 is installed on the connecting rod 6 inside the connection hole 18. The shape of the limiting block 19 is adapted to the connection hole 18. Then, under the action of the limiting block 19 and the connection hole 18, the connecting rod 6 is hinged with the first hinge part 16 and the second hinge part 17. Further, the end of the limiting block 19 away from the connecting rod passes through the connection hole 18 and is threadedly installed with a second fastening ring 20. When the second fastening ring 20 is tightened, the second fastening ring 20 is in close contact with the hinge part. Thus, the clamping force and frictional force generated after tightening are used to achieve the effects of fixing and limiting, so as to facilitate adjustment.
