Description

Technical Field

[0001] The invention relates to the field of unloading vehicles for mine ore material yards, and in particular to a multifunctional unloading vehicle that meets the process of ship unloading-mobile equipment-storage material yard. Background Art

[0002] At present, in terms of material yard unloading technology, the common method is to unload the materials by ship unloaders and other equipment, and then transport them to the stacker-reclaimer in the material yard through the ground belt conveyor system. The materials then fall onto the cantilever belt of the stacker-reclaimer through the head hopper of the tail car of the stacker-reclaimer, and finally the materials are piled into the material yard through the cantilever belt conveyor. This traditional material yard technology is mainly suitable for material yards with a relatively high transfer frequency, which is the so-called "fast in and fast out" mode.

[0003] However, with the continuous development of the market and the changes in demand, bulk coal or ore storage and transportation yards have gradually emerged. In this new situation, there are new considerations for the material turnover cycle and the overall cost and efficiency of the project. The traditional unloading process has exposed some shortcomings when facing the storage and transportation of bulk materials. For example, its equipment configuration cannot meet the needs of efficient transportation, resulting in a long material turnover time; and in terms of cost, both the equipment purchase cost and the civil engineering cost are relatively high. In addition, the operating model of the traditional process may not be flexible enough to adapt to different production needs and market changes.

[0004] Therefore, in order to better meet the needs of bulk coal or ore storage and transportation yards, improve material transfer efficiency, reduce costs, and enhance operational flexibility and adaptability, a new material yard process that is more efficient, convenient, and low-cost is urgently needed. This new process needs to be able to optimize the material transfer process, reduce unnecessary transfer links, improve equipment utilization, and effectively control costs while meeting production needs to adapt to market changes and development. Summary of the invention

[0005] In view of the fact that the above-mentioned storage and transportation yard cannot meet the demand for efficient transfer, resulting in a long material turnover time, a multifunctional unloading vehicle that meets the ship unloading-mobile equipment-storage yard process is provided. This device organically connects mature material transfer equipment such as bucket wheel excavators, grasshopper belt conveyors, mobile transfer machines and fan-shaped material placing machines in series, forming a new type of material yard unloading process that is efficient, convenient and low-cost to operate.

[0006] The technical means adopted by the present invention are as follows: A multifunctional unloading vehicle that meets the ship unloading-mobile equipment-stockpiling yard process, including: a hydraulic lifting tail car, a forked funnel, a traveling support steel structure, a two-way belt conveyor system, a cantilever belt conveyor head funnel, a lifting tail car head funnel, a traveling drive device, and a cable reel; The travel drive device includes a travel wheel frame, a travel reducer, a drive shaft and a drive motor. The travel wheel frame is connected to the travel support steel structure through a flange connection, and the travel reducer is connected to the drive shaft through a hollow shaft and a locking plate. The head funnel and forked funnel of the lifting tail car are connected to the walking support steel structure by bolts, and the hydraulic lifting tail car is connected to the main steel structure by a pin shaft device.

[0007] Furthermore, the hydraulic lift tail car can be switched between a horizontal state and a raised state.

[0008] Furthermore, the bifurcated funnel is used to divert materials to the left side or the right side or to two mobile equipment transfer lines, one on the left and one on the right.

[0009] Furthermore, the two bidirectional belt conveyor systems can select the running direction according to the position of the fixed material pile, and can carry out material separation by dual-line mobile equipment in a single-side material yard or in a double-side material yard.

[0010] Furthermore, the travel drive device can drive the unloading vehicle to move along the stacker-reclaimer track according to the actual position of the stockpile.

[0011] A ship unloading-mobile equipment-stockpiling yard process, the process flow of which includes: after the ship unloader unloads the material through a ground belt conveyor, the material is transferred through a forked funnel of a multifunctional unloading vehicle, and the material is diverted to the left or right side or two mobile equipment transfer lines, one on the left and one on the right; during the stockpiling process, the unloading vehicle can travel along the stacker track through a traveling drive device according to the actual position of the stockpiled material pile, so as to reduce the number of grasshopper transfer machines in operation.

[0012] Due to the adoption of the above technical solution, compared with the prior art, the present invention has the following advantages: 1.

When the process of ship unloading-mobile equipment-stockpiling yard is required, it can divert the unloaded materials to the left or right side or two mobile equipment transfer lines on the left and right. This flexible diversion method can better adapt to different stockyard layouts and production needs, and improve the flexibility and accuracy of material storage.

[0013] 2. The multifunctional unloading vehicle provided by the present invention meets the process of ship unloading-mobile equipment-storage yard, reduces the dependence on some traditional bulk material equipment, thereby saving expenses on equipment procurement. Due to its efficient transfer capacity, it may reduce the construction of some civil engineering facilities used for transit and storage, further reducing costs.

[0014] 3. The present invention provides a multifunctional unloading vehicle that meets the process of ship unloading-mobile equipment-storage yard, which has higher transfer efficiency, convenient operation, low operating cost, unmanned control, and a simpler and more efficient process flow. Through the reasonable design of the multifunctional unloading vehicle, such as the synergistic effect of components such as the forked funnel and the two-way belt conveyor system, the materials can be quickly diverted and transferred, reducing the residence time of the materials in the transfer process and improving the material transfer speed of the entire material yard.

[0020] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0025] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0026] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0027] like Figures 1 to 3As shown, a multifunctional unloading vehicle that meets the process of ship unloading-mobile equipment-stockpiling yard includes: a hydraulic lifting tail car 1, a forked funnel 2, a traveling support steel structure 3, a two-way belt conveyor system 4, a cantilever belt conveyor head funnel 5, a lifting tail car head funnel 7, a traveling drive device 6, and a cable reel; The running drive device 6 includes a running wheel frame, a running reducer, a driving shaft and a driving motor. The running wheel frame is connected to the running support steel structure 3 through a flange connection, and the running reducer is connected to the driving shaft through a hollow shaft and a locking plate. The head funnel and the forked funnel 2 of the lifting tail car are connected to the running support steel structure 3 by bolts, and the hydraulic lifting tail car 1 is connected to the main steel structure by a pin device.

[0028] Furthermore, the hydraulic lift tail car 1 can be switched between a horizontal state and a raised state.

[0029] Furthermore, the lifting function of the hydraulic lifting tail car 1 is realized by a hydraulic system, which includes a hydraulic pump, a hydraulic cylinder, a hydraulic pipeline and a control valve. The hydraulic pump provides power to transport the hydraulic oil to the hydraulic cylinder, and the flow and direction of the hydraulic oil are controlled by the control valve, thereby realizing the extension and retraction of the hydraulic cylinder, and then driving the lifting and lowering of the hydraulic lifting tail car 1.

[0030] Furthermore, the hydraulic lifting tail car 1 in a horizontal state is for "quick in and quick out" transit materials, adopting the process flow of ship unloader-ground belt conveyor-stacker-reclaimer-material pile. The free transformation of the hydraulic lifting tail car 1 does not affect the normal operation of the stacker-reclaimer on the same track, and the materials can pass directly through the unloading car.

[0031] Furthermore, when the hydraulic lift tail car 1 is in the raised state for a large coal or ore storage and transportation yard, and the process flow of ship unloader - ground belt conveyor - multi-functional unloading car - crawler mobile loader - fan-shaped material distributor - material pile is adopted, the hydraulic lift tail car 1 is in the raised state.

[0032] Furthermore, the bifurcated funnel 2 is used to divert materials to the left side or the right side or to two mobile equipment transfer lines, one on the left and one on the right.

[0033] Furthermore, when the material is transported from the ship unloader to the multifunctional unloading vehicle via the ground conveyor, the material enters the bifurcated funnel 2 after passing through the lifting tail vehicle head funnel 7. The bifurcated funnel 2 diverts the material to different directions according to actual needs, so as to better store the material in the storage pile.

[0034] Furthermore, the two bidirectional belt conveyor systems 4 can select the running direction according to the position of the fixed material pile, and can carry out material separation by dual-line mobile equipment in a single-side material yard, or can carry out material separation by dual-line mobile equipment in a double-side material yard.

[0035] Furthermore, when the hydraulic lifting tail car 1 is in the raised state, the material passes through the ground conveyor from the ship unloader, and is diverted into two paths through the lifting tail car head funnel 7 and the forked funnel 2 and transferred to the two bidirectional belt conveyor systems 4. The running direction of the two bidirectional belt conveyors is selected according to the position of the fixed material pile to achieve reasonable diversion and storage of materials.

[0036] Furthermore, the travel drive device 6 can drive the unloading vehicle to move along the stacker-reclaimer track according to the actual position of the stockpile.

[0037] like Figures 4 to 13 As shown, a process that meets the requirements of ship unloading-mobile equipment-stockpiling yard includes: after the ship unloader unloads the material through the ground belt conveyor, the material is transferred through the forked funnel 2 of the multifunctional unloading vehicle, and the material is diverted to the left or right side or two mobile equipment transfer lines on the left and right sides. During the stockpiling process, the unloading vehicle can move along the stacker track through the walking drive device 6 according to the actual position of the fixed material pile 8 to reduce the number of grasshopper transfer machines in operation.

[0038] Furthermore, for "quick in and quick out" transit materials, the process flow of ship unloader-ground belt conveyor-stacker-reclaimer-material pile is adopted. In this process, the hydraulic lifting tail car 1 of the multifunctional unloading car is in a horizontal state, and the materials can pass directly through the unloading car without affecting the normal material transfer process.

[0039] Furthermore, for large-scale coal or ore storage and transportation yards, a process flow of ship unloader-ground belt conveyor-multi-functional unloading vehicle-crawler mobile loader-fan-shaped material distributor-material pile is adopted. The material goes from the ship unloader to the multi-functional unloading vehicle via the ground belt conveyor. At this time, the hydraulic lifting tail car 1 is in a raised state, and the material passes through the lifting tail car head funnel 7 and the forked funnel 2, and the material is diverted into two paths and transferred to two bidirectional belt conveyor systems 4. The running direction of the two bidirectional belt conveyors is selected according to the position of the fixed material pile, and the material is transferred to the crawler mobile loader and the fan-shaped material distributor, and finally the material is stored.

[0040] 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 replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
