Description

Technical Field

[0001] The present application relates to the technical field of special equipment inspection, and in particular to a fork wear measuring device. Background Art

[0002] The fork is one of the main load-bearing components of the forklift. It is inevitable that it will be worn to varying degrees during use, especially the root of the horizontal section of the fork. When the fork thickness is less than 90% of the original value, the fork must be replaced to ensure the safe use of the forklift.

[0003] The wear of the fork must be measured during use and maintenance. At present, a steel ruler or vernier caliper is generally used to measure the thickness of the fork. A steel ruler or vernier caliper can only measure the thickness of the outer edge of the fork, and the thickness at the center line of the fork cannot be accurately measured. At the same time, the surface wear of the fork is in the form of a curved surface and the depth of the vernier caliper is limited. The numerical error of the steel ruler or vernier caliper method is large. Summary of the invention

[0004] The present application provides a fork wear measuring device, which has the advantage of facilitating accurate measurement of forklift fork wear and improving data accuracy and measurement efficiency.

[0005] The above-mentioned object of the present application is achieved through the following technical scheme: a fork wear measuring device, comprising a first laser ranging module, a second laser ranging module and a bracket, wherein the first laser ranging module is installed at a position above the fork through the bracket, and the second laser ranging module is installed at a position below the fork through a bracket, the first laser ranging module is directly opposite to the top of the fork for measuring the distance to the upper surface of the fork, and the second laser ranging module is directly opposite to the bottom of the fork for measuring the distance to the lower surface of the fork;

[0006] When measuring the wear of the forklift forks, the first laser distance measuring module and the second laser distance measuring module are located on a plumb line.

[0007] Furthermore, a reflective plate is provided on the first laser ranging module or the second laser ranging module.

[0008] Furthermore, the first laser ranging module and the second laser ranging module are provided with a level.

[0009] Furthermore, the bracket includes a magnetic base and a lever arm arranged on the magnetic base, and the first laser ranging module or the second laser ranging module is arranged at the end of the lever arm; the lever arm includes a plurality of connecting rods connected end to end.

[0010] Furthermore, it also includes a control box, which is provided with a main control unit, a display module, a storage module and a power supply module. The main control unit is connected to the first laser ranging module and the second laser ranging module to receive detection data of the first laser ranging module and the second laser ranging module, and the display module is used to display the detection result.

[0011] In summary, the beneficial effects of this application are:

[0012] 1. This application measures the thickness of the forklift fork through the first laser ranging module and the second laser ranging module, and the result is highly accurate. Compared with the traditional measurement using a vernier caliper, this application solution can obtain the thickness data of the middle part of the fork, and the data is more comprehensive;

[0013] 2. The first laser ranging module and the second laser ranging module of the present application are installed by a bracket, and the bracket has a magnetic base that can be quickly deployed, so that the present application solution is conducive to rapid arrangement for measurement and can be quickly disassembled after the measurement is completed;

[0014] 3. This application is easy to carry and does not require a designated location for use;

[0015] 4. When the fork wear is measured using the present application solution, all thickness data of the fork lateral dimension can be obtained by moving the fork, which is helpful for finding the maximum position of the fork wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1: A fork wear measuring device, referring to Figure 1 , including a first laser ranging module, a second laser ranging module and a bracket, the first laser ranging module is installed at a position above the fork through the bracket, the second laser ranging module is installed at a position below the fork through the bracket, the first laser ranging module is facing the top of the fork to measure the distance to the upper surface of the fork, and the second laser ranging module is facing the bottom of the fork to measure the distance to the lower surface of the fork.

[0022] The bracket includes a magnetic base and a lever arm arranged on the magnetic base, and the first laser ranging module or the second laser ranging module is arranged at the end of the lever arm; the lever arm includes a plurality of connecting rods connected end to end. The lever arm includes at least three connecting rods to meet the position adjustment requirements of the end of the lever arm. The connecting rod joints are connected by rotation, and a certain damping is maintained by pre-tightening, so that the position of the first laser ranging module or the second laser ranging module at the end of the lever arm can be maintained. In particular, pre-tightening screws are provided between the connecting rod joints, and the rotation damping between the connections is adjusted by loosening and tightening the screws.

[0023] When measuring the wear of forklift forks, the first laser distance measuring module and the second laser distance measuring module are located on a plumb line. A reflector is provided on the first laser distance measuring module or the second laser distance measuring module. In this embodiment, a reflector may be provided on the second laser distance measuring module.

[0024] The first laser distance measuring module and the second laser distance measuring module are provided with a level.

[0025] In this embodiment, the first laser distance measuring module and the second laser distance measuring module are both laser distance measuring devices. Currently, there are many laser distance measuring devices with digital display functions on the market, which can display measurement results.

[0026] When measuring the wear of forklift forks, first use two sets of brackets to install the first laser ranging module and the second laser ranging module to the upper and lower parts of the fork respectively. Specifically, the magnetic base in the bracket is adsorbed on the outer mast of the forklift. By adjusting the bracket, the first laser ranging module and the second laser ranging module are located on a plumb line. Use a level to determine whether the first laser ranging module and the second laser ranging module are in a horizontal position (the measurement direction is vertical). Then turn on the first laser ranging module to obtain the distance H between the first laser ranging module and the second laser ranging module (the reflector provided on the second laser ranging module is conducive to the first laser ranging module obtaining the distance H). The fork of the forklift is translated between the first laser ranging module and the second laser ranging module. The first laser ranging module and the second laser ranging module obtain the measurement results respectively, that is, the distance h1 from the first laser ranging module to the upper surface of the fork and the distance h2 from the second laser ranging module to the lower surface of the fork, and the thickness of the fork is h=H-h1-h2. By translating the fork, the thickness of several points on the horizontal line of the fork can be obtained. The positions of the first laser distance measuring module and the second laser distance measuring module are adjusted, and the above steps are repeated to obtain the thickness of the fork at different longitudinal points.

[0027] Embodiment 2: A fork wear measuring device, referring to Figure 1-3, including a first laser ranging module, a second laser ranging module and a bracket, the first laser ranging module is installed at a position above the fork through the bracket, the second laser ranging module is installed at a position below the fork through the bracket, the first laser ranging module is facing the top of the fork to measure the distance to the upper surface of the fork, and the second laser ranging module is facing the bottom of the fork to measure the distance to the lower surface of the fork.

[0028] The support structure and the embodiment are the same.

[0029] It also includes a control box, which is provided with a main control unit, a display module, a storage module and a power supply module. The main control unit is connected to the first laser ranging module and the second laser ranging module for receiving detection data of the first laser ranging module and the second laser ranging module, and the display module is used to display the detection result.

[0030] In this embodiment, the first laser ranging module and the second laser ranging module are laser ranging sensors, and their detection results are output to the main control unit through cables. The main control unit collects the detection results and displays them on the display module.

[0031] The above is only a preferred implementation of the present application. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present application, and these all fall within the scope of protection of the present application.
