[0018] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0019] The present invention provides a portal bucket wheel stacker-reclaimer tail car, such as Figure 1-Figure 5 As shown, including: Mainframe of gantry bucket wheel excavator 1, tail car I 2, belt conveyor of tail car I 3, material guide trough of tail car I 4, tail car II 5, material guide trough of tail car II 6, ground belt material guide trough 7, ground belt conveyor 8, head funnel of tail car II 9.

[0020] The tail car II5 is located on the right side of the tail car I2. The tail car II5 is equipped with a tail car II head funnel 9, a ground belt conveyor 8, a tail car II material guide trough 6, and a ground belt material guide trough 7; the tail car I2 is equipped with a tail car I belt conveyor 3 and a tail car I material guide trough 4.

[0021] like Figure 2 As shown, when the straight-through process is realized: the tail car II5 is pitched to a low position, the ground belt conveyor 8 receives incoming materials from the right side through the tail car II head funnel 9 and transfers them into the ground belt guide trough 7. The materials return to the ground belt conveyor 8 through the ground belt guide trough 7 and continue to be transported forward by turning to the left.

[0022] like Figure 3 As shown, when realizing the two-way reclaiming-main engine forward direction material conveying process: the tail car I 2 is pitched to the reclaiming position, and the material taken from the material yard by the portal bucket wheel excavator main engine 1 is conveyed to the right via the tail car I belt conveyor 3, and the right end of the tail car I belt conveyor 3 is unloaded to the tail car II material guide trough 6. At this time, the ground belt conveyor 8 runs to the left, and the material in the tail car II material guide trough 6 is conveyed to the left. The material on the ground belt conveyor 8 is transferred to the ground belt guide trough 7 via the tail car II head funnel 9. Since the ground belt conveyor 8 runs to the left, the ground belt conveyor 8 conveys the material in the ground belt conveyor 8 material guide trough to the left, thereby realizing the two-way reclaiming-main engine forward direction material conveying process.

[0023] like Figure 4 As shown, when realizing the process of bidirectional reclaiming - conveying materials in the backward direction of the main machine: the tail car I 2 is pitched to the reclaiming position, and the materials taken from the material yard by the portal bucket wheel excavator main machine 1 are conveyed to the right via the tail car I belt conveyor 3, and the right end of the tail car I belt conveyor 3 is unloaded into the tail car II material guide trough 6. At this time, the ground belt conveyor 8 runs to the right, and conveys the materials in the tail car II material guide trough 6 to the right, thereby realizing the process of bidirectional reclaiming - conveying materials in the backward direction of the main machine.

[0024] like Figure 5 As shown, when the forward stacking process is implemented: the tail car I 2 is pitched to the stacking position, the ground belt conveyor 8 receives materials from the right side through the tail car II head funnel 9 and transfers them into the tail car I guide chute 4. At this time, the tail car I belt conveyor 3 runs to the left, and the materials in the tail car I guide chute 4 are transported to the portal bucket wheel excavator main unit 1 through the tail car I belt conveyor 3. The materials are then stacked to the material yard through the portal bucket wheel excavator main unit 1.

[0025] The present invention can achieve straight-through function, two-way material collection (materials can be transported in the forward direction of the main machine or in the backward direction of the main machine), and forward stacking. It can provide construction units with diverse solutions, meet more functions, and save construction units' investment.

[0026] Example 2, based on Example 1, further includes: A gantry mounting frame 1 (existing technology, such as CN201665824U) is installed on the frame of the tail car I belt conveyor 3. Two front-to-back symmetrical electric slide rails (existing electric slide rails) are installed at the lower top of the gantry mounting frame 1. A vertical electric telescopic rod (existing electric telescopic rod) is installed at the moving end of the electric slide rail, and a push plate is installed at the lower end of the vertical electric telescopic rod.

[0027] Preferably, it further includes a conveying control device for controlling the tail car I belt conveyor 3, and the conveying control device includes: Speed ​​detection device: used to detect the conveying speed of the tail car I belt conveyor 3; Bulk material volume detection device: installed on the gantry mounting frame 2, the bulk material volume detection device is used to detect the bulk material volume of each belt area within a certain belt length area of ​​the gantry mounting frame 2. The conveying direction of the tail car I belt conveyor 3 is left and right, and the gantry mounting frame 2 is installed at a certain distance to the left and right of the gantry mounting frame 1; Several distance sensor groups: The width direction of the belt of the tail car I belt conveyor 3 is divided into several belt areas by a dividing line parallel to the length direction of the belt of the tail car I belt conveyor 3. Several belt areas correspond to several distance sensor groups one by one. Several distance sensors are installed at the lower part of the top of the second gantry mounting frame directly above each belt area; Storage device: stores the ideal load capacity range of each belt area at each conveying speed; Control device: The control device is electrically connected to the speed detection device, the distance sensor group, the storage device, the bulk material volume detection device, and the early warning device respectively.

[0028] Preferably, the control device includes: The first acquisition module is used to obtain the bulk material volume of each belt area detected by the bulk material volume detection device located on the side of the gantry mounting frame 1 close to the current output end of the tail car I belt conveyor 3; The second acquisition module is used to obtain the detection value of the speed detection device and the detection value of the distance sensor group; A first calculation module: used for calculating the adjustment demand coefficient of each belt area based on the first acquisition module; The first control module is used to control the first warning module of the warning device to issue a warning when the adjustment demand coefficient of any belt area is greater than a preset value of one; The second calculation module is used to calculate the load unevenness coefficient; The second control module is used to control the second warning module of the warning device to issue a warning when the load unevenness coefficient is greater than the preset value 2; The third control module: When any one of the first warning module and the second warning module issues an early warning, it is used to control the electric slide rail and the vertical electric telescopic rod to work and spread the material when the bulk material monitored by the bulk material volume detection device located on the side of the gantry mounting frame close to the current output end of the tail car I belt conveyor 3 reaches an area of ​​the gantry mounting frame.

[0029] Specifically, the lowering distance of the vertical electric telescopic rod is determined according to the position of the belt area with the predicted actual bearing capacity and the material height determined based on the detection value of the distance sensor of the corresponding distance sensor group, and the material in the belt area with the predicted actual bearing capacity is pushed to the belt area with the predicted actual bearing capacity.

[0030] Preferably, the first calculation module calculates based on the following formula: ; ; is the adjustment demand coefficient of the i-th belt zone; is the acceleration due to gravity; is the bulk material volume of the i-th belt area; The density of the bulk material currently being transported by the tail car I belt conveyor 3; is the maximum value of the ideal load-bearing capacity range of the i-th belt zone under the speed detection device; is the predicted actual bearing capacity of the i-th belt area; The maximum material height of the i-th belt zone is determined based on the detection value of the distance sensor; is the i-th belt area The maximum allowed value of The distance sensor of the i-th belt area is less than the preset distance value (the value can be greater than 0.6 times ) the total number of distance sensors; is the standard deviation of the detection value of the distance sensor in the i-th belt area; is the maximum allowable standard deviation of the distance sensor in the i-th belt area; 、 They are weight one and weight two (both values ​​are greater than 0 and less than 1); is the total number of distance sensors in the i-th belt area; The second calculation module is calculated based on the following formula: ; K is the load unevenness coefficient; is the maximum value of the predicted actual load-bearing capacity of all belt areas; is the minimum value of the predicted actual load capacity of all belt areas; The standard deviation of the predicted actual load capacity for all belt zones.

[0031] The beneficial effects of the above technical solution are: Through the bulk material volume detection device (3D profile scanning module such as LiDAR) and the distance sensor group (partition detection), the load distribution in the belt width direction can be monitored in real time, and the local overload area (such as a certain belt area with a large pile weight) can be accurately located.

[0032] Compared with traditional single-point detection, zone monitoring divides the belt width into several areas, and the detection accuracy is improved to ±1.5%, avoiding problems such as belt deviation and local wear caused by material overloading.

[0033] Adaptive Material Spreading Control: When the adjustment demand coefficient or uneven load coefficient in a particular area is detected to exceed a threshold, the electric slide rails and vertical electric telescopic rods are linked, and the pusher plate automatically levels the accumulated material, ensuring that the load capacity in each area approaches the ideal value. Application Value: For example, in the case of coal mine belts, this system can control widthwise load deviation to within 5%, extending belt life by over 30% and reducing downtime and maintenance costs caused by uneven loading.

[0034] Intelligent early warning and closed-loop control ensure system safety. The first warning module targets single-area overload (adjustment demand coefficient > preset value 1), while the second warning module targets overall uneven load (load unevenness coefficient > preset value 2), achieving multi-level risk prevention and control from "local anomaly" to "system imbalance."

[0035] The gantry mounting frame utilizes existing technology, with standard components such as electric slides and telescopic rods. It can be directly installed on existing tailcar conveyors, significantly reducing retrofit costs. Its multi-scenario applicability is suitable for conveyors of varying widths in mining, ports, and warehouses. By adjusting the number of zones (e.g., dividing the belt into 5-10 zones), it can be adapted to different operating conditions, providing exceptional flexibility.

[0036] Dynamic material spreading reduces belt eccentric wear and abnormal roller wear. It improves production efficiency and avoids frequent downtime adjustments due to eccentric loading, improving system operating efficiency while reducing waste caused by spilled materials.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
