Abstract
Description
Technical Field
[0001] This utility model relates to the field of loader technology, and in particular to an electric loader. Background Technology
[0002] Loaders are commonly used earthmoving equipment in mines and construction projects. Loaders used in mine tunnels, due to the deep underground location, narrow operating range, and lack of air, are now mostly electrically powered. Electric drive connects the loader's electrical equipment to a power source located in the tunnel via cables. During operation, the cable reel automatically winds up and unwinds the cable in sync with the loader's forward, backward, and speed adjustments. However, the cable reel winding and unwinding of existing electric loaders is constant, and its synchronization with the loader's speed and acceleration is not timely. This results in the cable either being too tight and pulled, or too loosely coiled and worn, reducing cable life and potentially creating electrical safety hazards. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an electric loader that is equipped with sensors that can detect the speed and acceleration of the loader. Combined with intelligent control, this allows the cable retraction and extension to match the vehicle's operating status in a timely manner, preventing the cable from being pulled or worn and extending its lifespan.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an electric loader, including a front frame and a rear frame connected by articulation, the front frame is equipped with a bucket, and the rear frame is equipped with a cab, a power motor, a transfer case, and a cable reel, the transfer case being connected to the front and rear wheels via a drive shaft; it also includes an intelligent cable winding and unwinding system; the intelligent cable winding and unwinding system includes the cable reel, a reel drive motor, a position sensor, a tension sensor, and an intelligent control module; the position sensor monitors the vehicle's driving status (including forward or backward movement, speed, and acceleration), the tension sensor detects the cable tension, and the intelligent control module adjusts the speed of the reel drive motor to match the cable winding and unwinding speed with the vehicle's driving status.
[0005] The drum drive motor, the position sensor, and the tension sensor are electrically connected to the intelligent control module. The intelligent cable winding and unwinding system works as follows: the position sensor monitors the vehicle's driving status, and the tension sensor obtains the cable tension. These two data are transmitted to the intelligent control module. After processing, the intelligent control module sends commands to the drum drive motor to control its forward or reverse rotation and its rotation speed, thereby matching the cable winding and unwinding speed to the vehicle's driving status and maintaining the cable tension within a certain range.
[0006] Preferably, the position sensor is a multi-functional sensor for monitoring vehicle driving status, or a collective term for multiple sensors. For example, a multi-functional sensor can be installed at the vehicle's center of gravity to directly monitor or monitor certain data and then calculate the vehicle's driving status. For instance, a sensor can be installed at the forward / reverse gear position to monitor whether the vehicle is moving forward or backward; a position sensor can be installed on the rear chassis to monitor vehicle displacement, and then perform displacement-time calculations to obtain speed and acceleration; wheel speed sensors can be installed at the wheel hubs to monitor vehicle speed and acceleration.
[0007] Preferably, the cable reel can be wound with a cable length of ≥80 meters.
[0008] Preferably, the intelligent control module uses a PID algorithm to adjust the winding and unwinding speed of the cable reel.
[0009] Preferably, the rear frame is provided with a guide device for guiding the cable.
[0010] The beneficial effects of this utility model are as follows: An electric loader is equipped with an intelligent cable winding and unwinding system. The intelligent cable winding and unwinding system includes a cable reel, a reel drive motor, a position sensor, a tension sensor, and an intelligent control module. The position sensor monitors the vehicle's driving status (including forward or backward movement, speed, and acceleration), the tension sensor detects the cable tension, and the intelligent control module adjusts the speed of the reel drive motor to match the cable winding and unwinding speed with the vehicle's driving status. This electric loader can monitor the vehicle's driving status in real time and control the speed of the cable reel through the intelligent control module, thereby controlling the cable winding and unwinding speed and tension, thus preventing the cable from being dragged or coiled and rubbed, and extending the cable's service life.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the present invention.
[0014] The operating environment for this embodiment is as follows: Location: 1000 meters underground in an iron mine; Topography: The alley is 3 meters wide and 2.5 meters high, and the ground is muddy (with water depth of 10cm) and gravel (5-10cm in diameter). Task: Transport ore from the mining area to the pass shaft, for a continuous 8-hour operation.
[0015] like Figure 1 , 2 As shown in this embodiment, an electric loader has a length of 6.1 meters, a width of 1.3 meters, and a height of 2 meters. The front and rear frames are hinged together by pins, and steering cylinders are installed on both sides of the hinge position. The steering cylinders are controlled by a steering wheel. The front frame 1 is equipped with a bucket 3, and the rear frame 2 is equipped with a cab 4, a power motor 5, a transfer case 6, and a cable reel 7. The transfer case 6 is connected to the front and rear wheels via a drive shaft. This electric loader is powered by a cable, and the cable is wound and unwound using the cable reel 7.
[0016] Due to the harsh working environment, whether manually driven or remotely controlled, the biggest problem this loader needs to solve in order to improve operational efficiency and reduce troubleshooting time is how to match the cable to the vehicle's driving status and ensure timely deployment and retraction. Because the cable is quite long, 80 meters, if it cannot be deployed in time, it will be pulled; if it cannot be retracted in time, it will become coiled or rub against the tunnel walls, causing cable damage and reducing its lifespan. Furthermore, if the cable cannot be retracted in time, it may get caught on the winding tunnel walls, requiring manual untangling and impacting operational efficiency.
[0017] Therefore, the loader in this embodiment is equipped with an intelligent cable winding and unwinding system, which includes the cable reel 7, the reel drive motor, the position sensor, the tension sensor 8, and the intelligent control module. The position sensor monitors the vehicle's driving status (including forward or backward movement, speed, and acceleration), the tension sensor 8 detects the cable tension, and the intelligent control module adjusts the speed of the reel drive motor to match the cable winding and unwinding speed with the vehicle's driving status.
[0018] Additionally, the rear frame 2 is equipped with a guide device 9 for guiding the cable, and the tension sensor 8 is located behind the guide device 9. The drum drive motor is a servo motor with a power of 10KW, electrically connected to the intelligent control module, and receives its control signals. The intelligent control module uses a PID algorithm to adjust the winding and unwinding speed of the cable drum.
[0019] The loader in this embodiment has a travel speed of 0-8 km / h, and the cable tension is set at 100 kN. Through testing, the operating efficiency of the existing loader and the loader in this embodiment is compared as follows:
[0020] As can be seen, this embodiment solves the problem of cable tangling, eliminating the need for manual cable handling and greatly improving the operating efficiency of the loader.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and for the convenience of describing the technical solution, the front, back, left, right, top, middle, and bottom orientations are based on the accompanying drawings and are not a limitation on the protection scope of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the essence and scope of the technical solution of this utility model.
