Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, in particular to an open-pit coal mine ecological restoration device and method designed for dikes and interception and drainage. Background Art

[0002] The spoil dump and exposed surface formed after open-pit coal mining need to be restored through systematic ecological restoration to achieve soil and water conservation and vegetation reconstruction. In this process, refined water management measures are the key basis for the success of ecological restoration. The commonly used technical means include: (1) Tianzi grid embankment system: by constructing mutually perpendicular grid-shaped low earth embankments in the restoration area, the site is divided into independent water collection units. Its core function is to block surface runoff, prolong the retention time of rainwater, promote local infiltration of rainwater, and reduce soil erosion; (2) shallow narrow interception drainage Canals: They are laid out along the boundaries of the restoration area or between units, and are mainly responsible for: intercepting external water from invading the restoration area, draining excess rainwater in the unit, and preventing vegetation damage caused by local waterlogging; however, in the subsequent ecological restoration construction phase, there is a conflict between mechanical operations and the above-mentioned soil and water conservation settings. Restoration equipment such as seeders and tillers need to frequently cross different restoration units for operation, and their walking trajectories will inevitably crush the dikes and cross the intercepting and drainage channels, causing the dikes to collapse and deform, and the channel structure to be damaged, thus seriously affecting the original functions of the dikes and intercepting and drainage settings.

DETAILED DESCRIPTION

[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] See also Figure 1 An open-pit coal mine ecological restoration device designed for dikes and intercepting drainage channels includes a carrier 1 for mounting ecological restoration work tools, the carrier 1 is provided with a frame 2 for crossing over the dike / intercepting drainage channel, and the frame 2 is symmetrically provided with several groups of supporting components 3 for supporting the ground to raise the carrier 1. The ecological restoration device also includes a spanning component 4 for driving the raised carrier 1 to move along the frame 2 to cross the dike / intercepting drainage channel.

[0025] It should be noted that the vehicle 1 in this application is a small or medium-sized vehicle, which is suitable for ecological restoration operations in small cells formed by the grid-shaped dike system in the mining restoration area, and the vehicle 1 has a light weight, which also facilitates the implementation of the scheme of lifting it across the dike / intercepting drainage channel in this application; the vehicle 1 is used to mount different types of ecological restoration equipment such as tillage, sowing, and fertilizing to carry out ecological restoration operations, and plays a traction role. The vehicle 1 is equipped with a corresponding power system, such as a diesel engine power system, an electric motor power system, etc., which is existing technology and will not be elaborated here.

[0026] When ecological restoration operations are carried out by towing operating equipment with vehicle 1 and it is necessary to cross the dike / intercepting drain, first adjust the orientation of vehicle 1 so that frame 2 spans over the dike / intercepting drain, and then use the ground support component to support the ground so that vehicle 1 is raised to a certain height (the raising height is determined according to the height of the dike to be crossed. Under the premise of ensuring that it can be crossed, the height of vehicle 1 is raised as low as possible to ensure safety. For the intercepting drain, it is sufficient to slightly raise vehicle 1 so that there are no substantial obstacles in its moving direction). Then, the raised vehicle 1 is driven along frame 2 by the spanning component 4 to cross the dike / intercepting drain, and finally, the ground support component 3 is reset so that the wheels of vehicle 1 touch the ground, thereby completing the dike / intercepting drain crossing action. During the ecological restoration operation, there is no damage to the dike / intercepting drain, ensuring the original functions of the dike and intercepting drain, thereby ensuring the long-term effect of ecological restoration.

[0027] See also Figure 1 and Figure 2 In one embodiment of the present invention, the shifting assembly 4 includes at least one slide groove 401 and a rack 404 provided on the frame 2. The slide groove 401 and the rack 404 have the same direction. The carrier 1 is provided with a connecting seat 402 that slides with the slide groove 401. The carrier 1 is also provided with a shaft 405 and a first driving member 403 for driving the shaft 405 to rotate. Preferably, the first driving member 403 is a permanent magnet synchronous motor, and the shaft 405 is provided with a gear 406 that meshes with the rack 404.

[0028] In this embodiment, when the carrier 1 is not raised, the shaft 405 is driven to rotate by the first driving member 403, and the frame 2 is driven to move under the meshing transmission action of the gear 406 and the rack 404 to achieve its reset action; when the carrier 1 is raised, the shaft 405 is driven to rotate by the first driving member 403, and the frame 2 is driven to move under the meshing transmission action of the gear 406 and the rack 404 to achieve the action of crossing the dike / intercepting the drainage channel.

[0029] See also Figures 1 to 3 In one embodiment of the present invention, the frame 2 includes a first frame 201 and a second frame 202 that are hingedly arranged. The second frame 202 can deflect relative to the first frame 201 so that the frame 2 as a whole is in a bent or flattened state. The frame 2 also includes a plurality of locking components for locking the first frame 201 and the second frame 202 in a flush state. The locking component includes a first boss 203 provided on the first frame 201, a second boss 205 provided on the second frame 202, and a first telescopic member 207 provided on 210 or the second frame 202 (the first telescopic member 207 is a telescopic cylinder, an electric telescopic rod, etc. in the prior art). The first boss 203 is provided with a first socket 204, and the second boss 205 is provided with a second socket 206. The aperture of the first socket 204 and the second socket 206 are consistent, and the first socket 204 and the second socket 206 are coaxial when the first frame 201 and the second frame 202 are flush. The movable end of the first telescopic member 207 is provided with a pin rod 208 adapted to the first socket 204 and the second socket 206.

[0030] In this embodiment, when there is no need to cross the dike / intercepting drainage channel, the frame 2 is in a bent state as a whole (that is, the first frame 201 remains unchanged, and the second frame 202 is deflected upward by a certain angle), thereby reducing the horizontal width (or vertical length) of the ecological restoration device, achieving the purpose of reducing the working space required for the ecological restoration device (in the horizontal direction), which is conducive to the flexible and convenient operation of the ecological restoration device; when there is a need to cross the dike / intercepting drainage channel, the second frame 202 is lowered and is flush with the first frame 201, that is, the frame 2 is in a flattened state as a whole, and the first telescopic member 207 is extended to drive the pin rod 208 to be inserted into the first socket 204 and the second socket 206, so that the first frame 201 and the second frame 202 are locked in a flush state, so that the subsequent carrier 1 crossing action can be performed.

[0031] See also Figure 1 In one embodiment of the present invention, the ecological restoration device also includes a retractable assembly 5 for driving the second frame 202 to deflect, and the retractable assembly 5 includes a mounting member 501 provided on the carrier 1, a reel 502 provided on the mounting member 501, and a second driving member 503 for driving the reel 502 to rotate (the second driving member 503 is a servo motor, a reduction motor, etc. in the prior art). A rope 504 is wound around the reel 502 (the rope 504 is a steel wire rope to ensure its strength and durability), and the movable end of the rope 504 is connected to the second frame 202; the second driving member 503 drives the reel 502 to rotate to pull / release the rope 504, so as to pull up and release the second frame 202 to adjust the overall state of the frame 2.

[0032] See also Figure 1In one embodiment of the present invention, the ground support assembly 3 includes a mounting base 301 provided on the frame 2 and a plurality of second telescopic members 302 arranged on the mounting base 301 (the second telescopic members 302 are electric telescopic rods, hydraulic telescopic rods, etc. in the prior art), a ground contact member 305 is provided at the lower end of the second telescopic member 302, and each second telescopic member 302 can be independently extended and retracted, and a pressure sensor (not shown in the figure) for detecting the contact pressure between the second telescopic member 302 and the ground is also provided between each second telescopic member 302 and the mounting base 301.

[0033] In this embodiment, the ground contact member 305 is driven to touch the ground by the synchronous extension of several second telescopic members 302, and the vehicle 1 is lifted up as the second telescopic members 302 continue to extend. The purpose of each second telescopic member 302 being able to extend and retract independently is that there are generally many pits or protrusions on the ground in the mining area, and the position of each second telescopic member 302 facing the ground is different (for example, some second telescopic members 302 face the pits, while some face the protrusions). The telescopic length of each second telescopic member 302 is adaptively adjusted according to the actual terrain and feedback is provided by the pressure sensor. When the pressure sensor senses that the pressure value reaches the set value, it means that the length of the corresponding second telescopic member 302 is adjusted to the right position (before the vehicle 1 is lifted up). At the same time, the influence of ground cavities (for example, the pits are covered with dead grass, fallen leaves, etc.) is avoided. After the lengths of all the second telescopic members 302 are adjusted to the right position, they are synchronously extended to lift the vehicle 1.

[0034] See also Figure 1 、 Figure 4 and Figure 5 In one embodiment of the present invention, a spiral cone 306 is provided on the ground contact member 305, and a sleeve 303 and a column 304 are provided between the lower end of the second telescopic member 302 and the ground contact member 305. The sleeve 303 is sleeved on the column 304, and the column 304 is uniformly provided with multiple spiral grooves 307 in the circumferential direction. The sleeve 303 is provided with a boss 309 that corresponds to and fits with the spiral grooves 307 one by one. The end of the boss 309 away from the inner wall of the sleeve 303 is stuck in the corresponding first telescopic member 207; A connecting piece 308 is rotatably embedded in the upper end of the column 304 , and an elastic member 310 is provided on the sleeve 303 . Both ends of the elastic member 310 are connected to the inner top of the sleeve 303 and the connecting piece 308 respectively.

[0035] In this embodiment, since the soil in the open-pit coal mine is relatively loose, in order to ensure that the ground contact member 305 is stably supported on the ground, especially when performing dike / interceptive drainage ditch crossing operations at a sloping mining area, the support stability of the ground contact member 305 is particularly important. Therefore, a spiral cone 306 is provided to enable it to be screwed into the soil. Specifically, the second telescopic member 302 extends to drive the ground contact member 305 to move downward, and the spiked end of the spiral cone 306 will touch the ground first. After the spiked end of the spiral cone 306 touches the ground, as the second telescopic member 302 continues to extend, the sleeve 303 begins to move downward relative to the column 304, prompting the spring 310 to apply downward pressure to the ground contact member 305. At the same time, the convex column 309 cooperates with the spiral groove 307, and the ground contact member 305 rotates so that the spiral cone 306 is screwed into the soil, which plays an anchoring effect and ensures the stability of the ground contact member 305.

[0036] See also Figure 2 In one embodiment of the present invention, the mounting seat 301 is hinged on the frame 2, and the connecting line between the ends of the plurality of second telescopic members 302, the center line of the mounting seat 301 and the rotation axis of the mounting seat 301 are located in the same plane. The ground support assembly 3 also includes a fastening component 311 for positioning the mounting seat 301 (the fastening component 311 can be a hydraulic locking structure (with a claw) in the prior art, or a brake locking structure, or other, which is not limited in this embodiment). When performing a dike / interceptor drainage ditch crossing action in a mining area with a slope, the orientation of the carrier 1 is adjusted so that the frame 2 spans over the dike / intercepting drainage channel and loosens the fastening component 311. Under the action of gravity, the several second telescopic components 302 are in a vertical downward state (not perpendicular to the slope surface), and then the mounting seat 301 is locked and positioned by the fastening component 311, so that the second telescopic components 302 are supported vertically downward on the slope surface, thereby eliminating the risk of overturning and ensuring the safety of the ecological restoration device in performing the dike / intercepting drainage channel spanning action on the slope surface; It should be noted that when there is no need to span the dike / intercepting drainage channel, the mounting seat 301 is also in a locked and positioned state by the fastening component 311 to prevent the mounting seat 301 from shaking and affecting the operation.

[0037] The present invention also provides an open-pit coal mine ecological restoration method for a dike and interception and drainage design, which uses an open-pit coal mine ecological restoration device for a dike and interception and drainage design as described in any one of the above technical solutions, including the following steps: S1: Carry out ecological restoration work by towing the working equipment with vehicle 1; S2: When it is necessary to cross the dike / intercepting drainage ditch, first adjust the orientation of the vehicle 1 so that the frame 2 spans over the dike / intercepting drainage ditch, and then use the ground support component to support the ground so that the vehicle 1 is raised to a certain height, and then use the span moving component 4 to drive the raised vehicle 1 to move along the frame 2 to cross the dike / intercepting drainage ditch, and finally reset the ground support component 3 so that the wheels of the vehicle 1 touch the ground, thereby completing the dike / intercepting drainage ditch crossing action.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
