Technical Field

[0001] This disclosure belongs to the technical field of load lifting, and particularly relates to a large-inclination orbital load lifting device. Background Art

[0002] At present, China's mining industry needs to meet the requirements of ecological civilization construction, green development, and the "dual carbon" action, and build a new development model with high resource utilization efficiency, environmental friendliness, low energy consumption, and low emissions. Currently, the production process of open-pit mines in China generally adopts the process method mainly based on single-bucket trucks. However, in the material transportation link of such processes, there are the following defects:

[0003] 1) The single-bucket truck for loading materials has a long transportation distance, and the vehicle has a large driving resistance when driving on the mine road. Especially on uphill sections, the fuel consumption is high and the efficiency is low, resulting in high transportation costs;

[0004] 2) During the material transportation process, the tires of single-bucket trucks are consumed in large quantities, the engines are worn out greatly, and the maintenance costs are high;

[0005] 3) During the material transportation process, single-bucket trucks have high carbon emissions and cause great environmental pollution;

[0006] 4) There are many cross-operations between ore material transportation and surrounding rock stripping material transportation. The driving blind area of single-bucket trucks is large, and potential safety hazards are prominent. Summary of the Invention

[0007] The embodiments of this disclosure provide a large-inclination orbital load lifting device, which can effectively solve the above technical problems. The technical solutions are as follows:

[0008] On the one hand, the embodiments of this disclosure provide a large-inclination orbital load lifting device, including a platform component, a track component, and a lifting component;

[0009] The track component includes an inter-sheet connection structure and at least two track sheets. Adjacent two track sheets are connected by the inter-sheet connection structure. The track sheet includes an upper track and a lower track. The upper track and the lower track are overlapped with each other. The two ends of the upper track and the lower track correspond and are connected respectively. The distance between the upper track and the lower track gradually increases from the end of the track sheet to the middle;

[0010] The lifting component is located between two adjacent track sheets. The lifting component includes a winch group, an upper-rail car and a lower-rail car. The upper-rail car is movably connected to the upper track. The lower-rail car is movably connected to the lower track. The winch group is connected to the track component. The steel wires of the winch group are respectively connected to the upper-rail car and the lower-rail car;

[0011] The platform component is connected to the track component, and the platform component is capable of adjusting the height and tilt angle of the track component relative to the horizontal plane.

[0012] In one implementation of this disclosure, the winch assembly includes two sets of friction winches;

[0013] Both sets of friction winches are located at the ends of the track assembly. The wire rope of one set of friction winches is connected to the upper rail car, and the wire rope of the other set of friction winches is connected to the lower rail car.

[0014] In one implementation of this disclosure, the platform component includes a lifting mechanism;

[0015] The lifting mechanism includes a lifting platform and pile legs. The lifting platform is movably sleeved on the pile legs and is connected to the track assembly.

[0016] In one implementation of this disclosure, the platform component further includes a tilt adjustment mechanism;

[0017] The tilt adjustment mechanism includes a raised platform and a hinge. The raised platform is hinged to the hinge. The portion of the raised platform away from the hinge is connected to the lifting platform, and the portion of the hinge away from the raised platform is connected to the track assembly.

[0018] In one implementation of this disclosure, the platform component further includes a sliding mechanism;

[0019] The sliding mechanism includes a sliding drive and a bracket. The sliding drive is connected to the bracket in a driving connection and is connected to the hinge seat. The bracket is connected to the track assembly.

[0020] In one implementation of this disclosure, the platform component further includes a pile shoe;

[0021] The pile shoe is connected to the end of the pile leg, and the pile shoe can move relative to the pile leg along its own plane and perpendicular to its own plane.

[0022] On the other hand, this disclosure provides a large-angle track-type load lifting device, including a top platform, a middle platform, a bottom platform, a track assembly, a friction winch, an upper rail car, and a lower rail car;

[0023] The upper rail car and the lower rail car cooperate with the track assembly through their respective traveling mechanisms and transmit loads. The friction winch pulls the upper rail car and the lower rail car to move up and down along the track assembly. The top platform, the middle platform and the bottom platform are respectively placed on support surfaces with different elevations. The top platform, the middle platform and the bottom platform are used to support the track assembly and adjust the position and attitude of the track assembly.

[0024] In one implementation of this disclosure, the track assembly consists of track sheet structures and inter-sheet connection structures. Each track sheet structure includes an upper track and a lower track. The upper track and the lower track are close to each other at both ends of the track assembly, and the upper track and the lower track are separated from each other at the middle part of the track assembly.

[0025] In one implementation of this disclosure, the friction winch pulls the upper rail car and the lower rail car via the friction winch drum and wire rope, and the upper rail car and the lower rail car run on the upper rail and the lower rail respectively via a traveling mechanism.

[0026] In one implementation of this disclosure, the top platform includes a platform main structure, a track sliding and tilt adjustment mechanism, a platform lifting mechanism, pile legs, and a platform lateral and longitudinal movement mechanism;

[0027] The track sliding and tilt adjustment mechanism cooperates with the track assembly to support the track assembly, enabling controllable relative sliding between the track sliding and tilt adjustment mechanism and the track assembly along the contact surface. The track sliding and tilt adjustment mechanism and the platform main structure can rotate relative to each other. The platform main structure and the pile leg are connected via the platform lifting mechanism, allowing relative lifting between the platform main structure and the pile leg and transferring the load of the platform main structure to the pile leg. A platform lateral and longitudinal movement mechanism is provided at the lower part of the pile leg, enabling the pile leg to move laterally and longitudinally relative to the support surface. The lateral movement refers to relative movement within the plane of the support surface that is perpendicular to the plane of the track sheet structure, and the longitudinal movement refers to relative movement within the plane of the support surface that is parallel to the plane of the track sheet structure.

[0028] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0029] In the operation of the high-angle track-type load lifting device provided in this embodiment, two adjacent track panels form a group. The upper track of the two adjacent track panels works together to provide an installation foundation and moving track for the upper rail car, and the lower track of the two adjacent track panels works together to provide an installation foundation and moving track for the lower rail car. In this way, two adjacent track panels can provide installation foundations and moving tracks for both the upper and lower rail cars. In addition, since the ends of the upper and lower track are corresponding and connected, the starting and ending points of the two cars are ensured to be the same. Furthermore, since the upper and lower track are stacked on top of each other, and their middle sections are spaced apart, when the upper rail car starts from one end of the track panel and moves along the upper track, the lower rail car starts from the other end of the track panel and moves along the lower track. That is, when the upper and lower rail cars move towards each other, they can be staggered when they reach the middle of the track panel and will not affect each other. In other words, a set of track panels allows both the upper and lower track cars to work simultaneously, effectively improving work efficiency.

[0030] By using upper and lower rail cars to transport trucks, the inclined rail-type load lifting equipment can achieve lifting capabilities with large inclination angles and large carrying capacity, and has no special requirements on the shape of the large load materials.

[0031] By adjusting the height and tilt angle of the track assembly relative to the horizontal plane through the platform components, the large-angle track-type load lifting equipment can have flexible overall movement function, coordinate with the mining process activities such as stripping, mining and dumping, and dynamically advance the overall process rhythm of mining transportation without affecting the mining site. It can also adapt to the shape changes of the open-pit mine end face and has the function of attitude self-adjustment.

[0032] Because the inclined track-type load lifting equipment is directly erected from the bottom of the mine to the top, the spatial layout does not interfere with other transportation activities of the internal discharge process, ensuring coordination and safety. It also shortens the truck transportation distance, achieves energy saving and consumption reduction, and replaces oil with electricity, which can significantly reduce carbon emissions and road dust.

[0047] Currently, China's mining industry needs to benchmark against the requirements of ecological civilization construction, green development and the "dual carbon" actions, and build a new development model with high resource utilization efficiency, environmental friendliness, low energy consumption and low emissions. At present, the production process of open-pit mines in China generally adopts the process method mainly based on single-bucket trucks. However, in the material transportation link of such processes, there are the following defects:

[0048] 1) The single-bucket trucks loading materials have a long transportation distance, and the driving resistance of the vehicles on the mine roads is large. Especially on uphill sections, the fuel consumption is high and the efficiency is low, resulting in high transportation costs;

[0049] 2) During the material transportation process, the tires of single-bucket trucks are consumed in large quantities, the engines are worn out greatly, and the maintenance costs are high;

[0050] 3) During the material transportation process, the carbon emissions of single-bucket trucks are high and the environmental pollution is large;

[0051] 4) There are many cross-operations between ore material transportation and waste rock stripping material transportation. The blind spots of single-bucket trucks during driving are large, and the potential safety hazards are prominent.

[0052] To solve the above technical problems, the embodiments of the present disclosure provide a large-inclination track-type load lifting device. Figure 1 For the structural schematic diagram of the large-inclination track-type load lifting device, see Figure 1 , the large-inclination track-type load lifting device includes a platform component 1, a track component 2 and a lifting component 3.

[0053] The track assembly 2 includes an inter-piece connecting structure 21 and at least two track pieces 22. Adjacent track pieces 22 are connected by the inter-piece connecting structure 21. Each track piece 22 includes an upper track 221 and a lower track 222, which are stacked on top of each other. The two ends of the upper track 221 and the lower track 222 are respectively corresponding and connected. The distance between the upper track 221 and the lower track 222 gradually increases from the ends of the track pieces 22 towards the middle. The lifting assembly 3 is located between two adjacent track pieces 22. The lifting assembly 3 includes a winch assembly 31, an upper rail car 32, and a lower rail car 33. The upper rail car 32 is movably connected to the upper track 221, and the lower rail car 33 is movably connected to the lower track 222. The winch assembly 31 is connected to the track assembly 2, and the wire rope 312 of the winch assembly 31 is connected to the upper rail car 32 and the lower rail car 33 respectively. Platform component 1 is connected to track component 2, and platform component 1 can adjust the height and tilt angle of track component 2 relative to the horizontal plane.

[0054] During the operation of the high-angle track-type load lifting device provided in this embodiment, two adjacent track plates 22 form a group. The upper track 221 of the two adjacent track plates 22 works together to provide an installation foundation and moving track for the upper rail car 32, and the lower track 222 of the two adjacent track plates 22 works together to provide an installation foundation and moving track for the lower rail car 33. In this way, the two adjacent track plates 22 can provide an installation foundation and moving track for both the upper rail car 32 and the lower rail car 33. In addition, since the ends of the upper track 221 and the lower track 222 are corresponding and connected, it is ensured that the starting point and ending point of the two cars are the same. Furthermore, since the upper track 221 and the lower track 222 are stacked on top of each other, and their middle sections are spaced apart, when the upper track car 32 starts from one end of the track plate 22 and moves along the upper track 221, the lower track car 33 starts from the other end of the track plate 22 and moves along the lower track 222. That is, when the upper track car 32 and the lower track car 33 move towards each other, they can be staggered when they reach the middle of the track plate 22 and will not interfere with each other. In other words, a set of track plates 22 can allow the upper track car 32 and the lower track car 33 to work simultaneously, effectively improving work efficiency.

[0055] By transporting trucks via the upper rail car 32 and the lower rail car 33, the inclined rail load lifting equipment can have the lifting capacity of large inclination angle and large carrying capacity, and there are no special requirements for the shape of the large load material.

[0056] By adjusting the height and tilt angle of the track component 2 relative to the horizontal plane through the platform component 1, the large-angle track-type load lifting equipment can have flexible overall movement function, coordinate with the mining process activities such as stripping, mining and dumping, and dynamically advance the overall process rhythm of mining transportation without affecting the mining site. It can also adapt to the shape changes of the open-pit mine end face and has the function of attitude self-adjustment.

[0057] Because the inclined track-type load lifting equipment is directly erected from the bottom of the mine to the top, the spatial layout does not interfere with other transportation activities of the internal discharge process, ensuring coordination and safety. It also shortens the truck transportation distance, achieves energy saving and consumption reduction, and replaces oil with electricity, which can significantly reduce carbon emissions and road dust.

[0058] In this embodiment, a support frame is provided between the upper track 221 and the lower track 222 of the same track sheet 22 so that the upper track 221 and the lower track 222 are connected as a whole.

[0059] Figure 2 This is a schematic diagram of the arrangement of track assembly 2. Figure 2 for Figure 1 The bird's-eye view, combined with Figure 2 In this embodiment, the winch assembly 31 includes two sets of friction winches 311.

[0060] Both sets of friction winches 311 are located at the ends of the track assembly 2. The wire rope 312 of one set of friction winches 311 is connected to the upper rail car 32, and the wire rope 312 of the other set of friction winches 311 is connected to the lower rail car 33.

[0061] In the above implementation, the two friction winches 311 correspond to the upper rail car 32 and the lower rail car 33 respectively, and can respectively control the traction of the upper rail car 32 and the lower rail car 33. This not only ensures the traction force of the winch group 31 on the upper rail car 32 and the lower rail car 33, but also ensures that the upper rail car 32 and the lower rail car 33 can pass each other in the middle of the track sheet 22, thus avoiding collision accidents between the upper rail car 32 and the lower rail car 33.

[0062] Depend on Figure 2 As you can see, Figure 2The diagram shows three track panels 22, which can support the simultaneous operation of four cars (two upper track cars 32 and two lower track cars 33). One track panel 22 and the middle track panel 22 support two cars (one upper track car 32 and one lower track car 33) simultaneously, while the other track panel 22 and the middle track panel 22 support another two cars (one upper track car 32 and one lower track car 33) simultaneously. In other words, the middle track panel 22 can be used in conjunction with the adjacent track panels 22 on either side. For example, if the track system includes four track panels 22, it can support the simultaneous operation of six cars (three upper track cars 32 and three lower track cars 33). If the track system includes five track panels 22, it can support the simultaneous operation of eight cars (four upper track cars 32 and four lower track cars 33). That is, n track pieces 22 arranged side by side can support (n-1)*2 cars to work at the same time.

[0063] In this embodiment, when the upper rail car 32 and the lower rail car 33 move, if the upper rail car 32 descends and the lower rail car 33 rises, then the upper rail car 32 can act as a counterweight for the lower rail car 33. Conversely, the lower rail car 33 acts as a counterweight for the upper rail car 32, thereby further reducing energy consumption.

[0064] Figure 3 This is a structural diagram of platform component 1, combined with... Figure 3 In this embodiment, the platform component 1 includes a lifting mechanism 11, which includes a lifting platform 111 and a pile leg 112. The lifting platform 111 is movably sleeved on the pile leg 112, and the lifting platform 111 is connected to the track component 2.

[0065] In the above implementation, the lifting platform 111 and the pile leg 112 can be movably installed together via a gear and rack mechanism. The gear in the gear and rack mechanism is located inside the lifting platform 111, and the rack of the gear and rack mechanism is located on the pile leg 112 and extends along the length of the pile leg 112.

[0066] See also Figure 3 In this embodiment, the platform assembly 1 further includes a tilt adjustment mechanism 12, which includes a raised platform 121 and a hinge 122. The raised platform 121 is hinged to the hinge 122. The portion of the raised platform 121 away from the hinge 122 is connected to the lifting platform 111, and the portion of the hinge 122 away from the raised platform 121 is connected to the track assembly 2.

[0067] In the above implementation, the raised platform 121 is used to increase the distance between the track assembly 2 and the lifting platform 111, thereby providing space for the track assembly 2 to tilt and avoiding interference and collision between the track assembly 2 and the lifting platform 111 when tilting.

[0068] For example, the rotation of the hinge 122 relative to the raised platform 121 can be driven by a motor.

[0069] See also Figure 3 In this embodiment, the platform component 1 further includes a sliding mechanism 13, which includes a sliding drive component 131 and a bracket 132. The sliding drive component 131 is connected to the bracket 132 in a transmission manner. The sliding drive component 131 is connected to the hinge seat 122, and the bracket 132 is connected to the track component 2.

[0070] In the above implementation, the sliding mechanism 13 connects the track assembly 2 and the tilt adjustment mechanism 12. Furthermore, through the sliding mechanism 13, the track assembly 2 can slide relative to the tilt adjustment mechanism 12 to a certain extent along the length direction, thereby making the arrangement of the large tilt angle track load lifting equipment more flexible.

[0071] See also Figure 3 In this embodiment, the platform component 1 also includes a pile shoe 14, which is connected to the end of the pile leg 112. The pile shoe 14 can move relative to the pile leg 112 along its own plane and perpendicular to its own plane.

[0072] In the above implementation, the pile shoe 14 can move relative to the pile leg 112 along its own plane and perpendicular to its own plane under the drive of the driver, thereby adjusting the position of the pile leg 112 and making the arrangement of the large-angle track-type load lifting equipment more flexible.

[0073] For example, when the pile shoe 14 is placed on the ground, the plane on which the pile shoe 14 is located is the ground, and the actuator is a hydraulic cylinder.

[0074] Figure 4 This is a schematic diagram of the adjustment of a high-angle track-type load lifting device, combined with... Figure 4 Platform component 1 enables track component 2 to translate along the ground, rise and fall perpendicular to the ground, tilt relative to the ground, slide relative to the ground along its own length direction and perpendicular to its own length direction.

[0075] See you again Figure 1In this embodiment, the inclined track-type load lifting equipment includes: a top platform, a middle platform, a bottom platform, a track assembly 2, a friction winch 311, an upper rail car 32, and a lower rail car 33. The upper rail car 32 and the lower rail car 33 cooperate with the track assembly 2 through their respective traveling mechanisms to achieve load transfer. The friction winch 311 pulls the upper rail car 32 and the lower rail car 33 to move up and down along the track assembly 2. The top platform, middle platform, and bottom platform can be placed on support surfaces with different elevations and are used to support the track assembly 2, and can also be used to adjust the position and attitude of the track assembly 2. The interiors of the upper rail car 32 and the lower rail car 33 are used to accommodate material transport vehicles such as open-pit mine cars or hoppers. The total number of platforms corresponding to the top platform, middle platform, and bottom platform can be flexibly adjusted according to specific engineering operation requirements; that is, the total number of platforms is not necessarily as specified above. Figure 1 There are three platforms. The elevations of the supporting surfaces corresponding to the top, middle, and bottom platforms can be flexibly adjusted according to specific engineering operation requirements; that is, the elevations of the supporting surfaces corresponding to each platform do not necessarily need to be unequal. The term "supporting surface" refers to geological structures or other similar structures used to support the open-pit mine vehicle transport steps for lifting equipment with large-angle track loads. The term "elevation" refers to the height of the supporting surface along the direction of increase or decrease in the potential energy of the lifted material load, such as the elevation of the vehicle transport steps in open-pit mine mining and transportation processes.

[0076] See also Figure 1 In this embodiment, the track assembly 2 consists of track panels 22 and inter-panel connecting structures 21. Each track panel 22 includes an upper track 221 and a lower track 222. The spacing between the upper track 221 and the lower track 222 is such that they approach each other at both ends of the track assembly 2 and separate at the middle. The purpose of this design is that when the upper rail car 32 and the lower rail car 33 are located at the ends of the track assembly 2, their positions relative to the support surface remain essentially unchanged, thus facilitating the entry and exit of material loads within the car. When the upper rail car 32 and the lower rail car 33 are simultaneously located near the middle of the track assembly 2, their running trajectories can avoid each other spatially, preventing interference. In the above track assembly 2, every two adjacent track panels 22 form a car running channel, such as... Figure 2 The system consists of three track pieces 22 forming two car running channels. Each car running channel can provide lifting and lowering operation for the upper rail car 32 and the lower rail car 33 respectively, thus providing simultaneous operation for four cars. Therefore, the number of track pieces 22 included in the track assembly 2 can be flexibly adjusted according to the material lifting capacity requirements. For example, when it includes four track pieces 22, it can form three car running channels, allowing six cars to operate simultaneously, and so on.

[0077] See also Figure 1 In this embodiment, the friction winch 311 pulls the upper rail car 32 and the lower rail car 33 through the friction winch drum and the wire rope 312. The upper rail car 32 and the lower rail car 33 run on the upper rail 221 and the lower rail 222 respectively through the traveling mechanism. The upper rail car 32 and the lower rail car 33 are counterweights to each other. When the upper rail car 32 is raised, the upper rail car 32 is lowered, and when the upper rail car 32 is lowered, the upper rail car 32 is raised, thereby achieving the purpose of energy saving.

[0078] See you again Figure 3 In this embodiment, the top platform, middle platform, and bottom platform all have similar functional structures. The top platform will be used as an example for explanation below. The top platform includes a main platform structure, a track sliding and tilt adjustment mechanism, a platform lifting mechanism, pile legs 112, and a platform lateral and longitudinal movement mechanism. The main platform structure is similar to the lifting platform 111, the track sliding and tilt adjustment mechanism is similar to the tilt adjustment mechanism 12 and the sliding mechanism 13, and the platform lateral and longitudinal movement mechanism is similar to the pile shoe 14.

[0079] The track sliding and tilt adjustment mechanism works in conjunction with and supports the track assembly 2. Simultaneously, the two can slide relative to each other controllably along the support surface. The track sliding and tilt adjustment mechanism can also rotate relative to the platform main structure. These functions allow the track assembly 2 to be adjusted in relative position and tilt angle while being supported by the platform main structure. The platform main structure and the pile legs 112 are connected via a platform lifting mechanism, enabling relative lifting and lowering movements between the platform main structure and the pile legs 112, and transferring loads to the pile legs 112. The number of pile legs 112 can be rationally arranged according to the specific needs of the project. When the support surface corresponding to each pile leg 112 has a different elevation, the lifting and lowering movements of the platform lifting mechanism corresponding to each pile leg 112 can be adjusted separately, ensuring that the platform main structure remains horizontal. A platform lateral and longitudinal movement mechanism is provided at the lower part of the pile leg 112. This mechanism allows the pile leg 112 to move laterally and longitudinally relative to the supporting surface. Lateral movement refers to relative movement within the plane of the supporting surface that is perpendicular to the plane of the track plate 22, while longitudinal movement refers to relative movement within the plane of the supporting surface that is parallel to the plane of the track plate 22. Through the coordinated movement of the platform lateral and longitudinal movement mechanisms of each pile leg 112, the movement of each platform, such as the top platform, middle platform, and bottom platform, within their respective supporting surfaces can be achieved.

[0080] Since each platform of the large-angle track-type load lifting equipment, such as the top platform, middle platform and bottom platform, can move within its respective support surface, and each platform can slide and adjust its tilt relative to the track assembly 2, the large-angle track-type load lifting equipment has the function of overall movement and attitude adjustment, thus enabling it to adapt to various matching combinations of different support surfaces and elevations in actual engineering.

[0081] The inclined track-type load lifting device disclosed herein has at least the following innovative features:

[0082] 1) The inclined track-type load lifting equipment can adapt to the inclined characteristics of the open-pit mine end wall and can achieve large-capacity load lifting.

[0083] The inclination angle of open-pit mine end walls is generally between 20° and 40° (but not limited to this range). Conventional belt conveyors typically have an angle no greater than 15° and have requirements regarding the shape of the material, requiring processing such as crushing. The material carrying capacity of belt conveyors is also often limited. However, this large-angle track-type load lifting equipment is not subject to these limitations. It has the lifting capacity for large inclination angles and large carrying capacity, and has no special requirements regarding the shape of the large load material.

[0084] 2) This inclined track-type load lifting equipment has a flexible overall movement function (the relocation path can be automatically planned), which can be coordinated with the mining stripping, mining and dumping processes, and does not affect the dynamic progress of the overall process rhythm of mining transportation.

[0085] 3) This inclined track-type load lifting equipment can adapt to the shape changes of the open-pit mine end face and has the function of attitude self-adaptive adjustment.

[0086] During open-pit mining, parameters such as the ore layer, endwall height, slope angle, number of steps, and step height dynamically change with the production progress. This steep-angle track-mounted load lifting equipment has an adaptive attitude adjustment function, which can adapt to the dynamic changes in the aforementioned endwall morphology.

[0087] 4) The spatial layout of this inclined track-type load lifting equipment does not interfere with other transportation activities of the internal discharge process and is coordinated and safe.

[0088] The top, middle, and bottom platforms of this inclined track-type load lifting equipment are respectively located on the crushing station steps and the top of the coal seam. It can take into account the end-side transportation needs of open-pit mine vehicles, avoid plane intersection with the internal transportation process path, meet the three-dimensional transportation conditions, and make the coal feeding process and soil dumping process complementary and complementary, thereby improving their coordination and safety.

[0089] 5) This inclined track-type load lifting equipment shortens the transportation distance of coal trucks (especially the uphill transportation distance), realizes energy saving and consumption reduction and replaces oil with electricity, and can significantly reduce carbon emissions and road dust.

[0090] 6) This inclined track-type load lifting equipment can serve as a carrier of advanced information technology to improve the intelligent management level of coal feeding process.

[0091] By adding corresponding sensors or related analysis equipment to this mining truck transportation system, dynamic statistics of data such as coal feeding capacity, mining truck transportation load, and coal composition pre-analysis can be achieved, providing support for the intelligent management of coal feeding process.

[0092] 7) This large-angle track-type load lifting equipment is integrated with unmanned mining truck technology, which reduces the technical difficulty of unmanned mining trucks, improves the transportation efficiency of unmanned mining trucks, and provides a more convenient technical path for the construction of smart mines.

[0093] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
