Description

Technical Field

[0001] This utility model relates to the field of equipment technology, and in particular to a portable track installation quality inspection tool. Background Technology

[0002] Currently, in traditional construction and maintenance fields, especially in the application of aerial work platforms, track installation and maintenance measurements are typically performed using levels and theodolites to measure the elevation and straightness of the entire track length. Traditional methods usually involve setting up safety ropes on the track beams, with workers using instruments mounted on the beams for measurement. This method requires production to stop, takes a long time, and carries significant safety risks due to working at heights. This is especially true for busy continuous production lines and environments with high temperatures, toxicity, and high dust levels, where the work is even more difficult and inconvenient. Utility Model Content

The control and analysis unit controls the operation of the internal motor after receiving the signal from the second gyroscope sensor. Furthermore, the control and analysis unit described in this utility model includes a data signal receiving and analyzing instrument and an execution controller, which are integrated into one unit. The data signal receiving and analyzing instrument is used to receive data information sent from various devices and perform analysis and calculation. Then, the execution controller controls the operation of the drive mechanism and the balancing module.Furthermore, the bracket structure described in this utility model includes an ear plate support 14, a first connecting plate 13, and a second connecting plate 12. The ear plate support is fixedly disposed at the center of the front end of the machine body. The first connecting plate is connected to the ear plate support by bolts and nuts. The front end of the second connecting plate is also connected to the first connecting plate by bolts and nuts. The second connecting plate is connected to the cross-sectional profile scanner by bolts and nuts.

[0021] This invention incorporates an intelligent data acquisition device mounted on the main body of a machine. The main body is designed with a symmetrical structure and uniform mass distribution. Specifically, it comprises a cross-sectional profile scanner for scanning the track and an infrared laser rangefinder. The profile scanner scans the cross-section of the track under test, facilitating adjustment of the measuring tool's fixed position and determining the initial coordinates of the track's centerline and their changes during movement. The infrared laser rangefinder sets the initial elevation of the track's initial point and tracks its changes during operation.

[0022] The data signal receiver and analyzer is powered by a battery pack (or rechargeable battery) to receive various data collected by intelligent data acquisition devices. It analyzes and processes the data through built-in programs, generating linear charts as output. It also has built-in storage capabilities and can transfer data files via a computer connection. It is typically mounted on the main unit during use (it is detachable).

[0023] The transmission line is a dedicated connection cable for signal and power transmission between the data signal receiver and analyzer and the intelligent data acquisition device, using a universal connector.

[0024] Data measurement involves automatically acquiring the track's three-dimensional shape and coordinate data using a front-end profile scanner and a rear-end infrared laser rangefinder. This data is then transmitted to the control and analysis unit, where simulation analysis determines the track's position in three-dimensional space, thereby assessing whether the track's elevation, straightness, span, and other installation quality meet specifications. All measurement data, coordinate data, and the track's three-dimensional shape can be downloaded or transferred via USB flash drive, Bluetooth, or data cable.

[0025] In this utility model, the drive mechanism is equipped with two rechargeable lithium battery packs to power the bottom wheel drive motor and other components, with a battery life of not less than 2 hours. The overall balance control principle of the device is similar to that of existing unicycle balancers. The device maintains balance while moving along the track. Specifically: front-to-back balance is controlled by the bottom wheels. A first gyroscope sensor monitors the front-to-back tilt angle in real time and feeds it back to the control analysis unit 3. After rapid calculation (internal program control), the speed of the drive motor and the bottom wheels is adjusted to achieve front-to-back angle balance, controlling the tilt angle to maintain stability. Left-to-right balance is controlled by the balance wheels, controlling the tilt angle to maintain stability. Specifically, a second gyroscope sensor monitors the left-to-right tilt angle in real time and feeds it back to the control analysis unit 3. After rapid calculation, the speed of the internal motor and the two balance wheels on both sides is adjusted to achieve left-to-right angle balance, controlling and adjusting the tilt angle in real time to maintain stability. Limiting rollers assist in controlling the smoothness of straight-line travel and assist in calculating the travel distance, thus achieving self-balancing and stable straight-line movement of the entire device on the crane track, enabling measurement and detection. Existing self-balancing wheels also basically operate on this principle.

[0026] As for the front support structure, since it is composed of ear plate support 14, first connecting plate 13 and second connecting plate 12, its support height and angle can be adjusted at any time, thereby adjusting the installation height and angle of the front cross-sectional shape scanner to achieve better scanning measurement.

[0027] The use of the entire device of this utility model:

[0028] 1. Place the entire equipment on the track;

[0029] 2. Install the intelligent data acquisition device on the machine body, roughly adjust its orientation, and then temporarily fix it in place;

[0030] 3. Install the control and analysis unit on the equipment body and secure it firmly, and connect all data transmission lines;

[0031] 4. Turn on the power of the data signal receiver and analyzer, set the working mode, fine-tune the orientation of the intelligent data acquisition device so that the track cross-section data it acquires matches the track form in the preset mode, and set the initial point coordinates and the end point coordinates (X, Y, Z), generally set to (0.00, 0.00, 0.00). At the same time, input the theoretical value of the total track length and set the program to intermittently acquire track data values.

[0032] 5. Start the equipment and run the portable track installation quality inspection tool of this utility model along the entire length of the track without interrupting the power supply;

[0033] 6. After reaching the endpoint, save the collected measurement results. To reduce errors, the measurement can be reversed and another set of data can be measured for comparison.

[0034] 7. Open the data output by the control analysis unit on the computer to view the various installation data of the track intuitively, providing a basis for adjusting the track.

[0035] The use of this utility model can objectively and effectively reflect the installation data of the track in space. While ensuring the authenticity of the data, it reduces the safety risks of measurement and improves the measurement quality. This tool only requires the entire device to be placed on the trolley track to collect data, avoiding the need for surveyors to work at heights on the trolley track beam. Compared with traditional surveying tools such as levels and theodolites, it has advantages such as smaller measurement errors and fewer restrictions due to environmental influences.
