Description

Technical Field

[0001] The invention relates to open-pit mining, and in particular to a device for fixing a slope of an open-pit mine dump. Background Art

[0002] Open-pit mining is a process in which the loose soil and surrounding rock covering the upper part of the ore body and its surroundings are stripped away and transported to the spoil dump, and then the ore is directly mined from the exposed ore body.

[0003] As the scale of open-pit mines continues to expand and production increases, the volume of spoil dumps is getting larger and larger, far exceeding the common soil slopes, and the slope management of spoil dumps has become a top priority. Under the influence of long-term weathering, rainwater erosion, complex geological conditions and other comprehensive factors, open-pit mine spoil dumps are prone to landslides and step instability, which are very likely to cause safety accidents and seriously threaten the safe production of open-pit mines.

[0004] At present, the slope management of open-pit mine spoil dumps usually adopts a combination of simple active flexible protection nets and ordinary mortar anchor bolts. This construction plan has a long construction period and high cost. In addition, under the impact of rainwater, the anchor bolts are very easy to detach from the spoil dump, causing the slope of the spoil dump to become unstable. Summary of the invention

[0005] The technical problem to be solved by the present invention is that, in view of the problem that the anchor rods of the slope of an open-pit mine dump are easily dislodged, the present invention provides an open-pit mine dump slope fixing device which is not easily dislodged from the slope soil body.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A device for fixing the slope of an open-pit mine dump, comprising:

[0008] The rod body comprises a main body portion and a cone portion provided at one end of the main body portion, wherein the main body portion is provided with a receiving cavity, and the main body portion is provided with a plurality of through holes extending from the outer wall of the main body portion to the receiving cavity in layers, and the through holes in the same layer are arranged opposite to each other;

[0009] A first fixing assembly, comprising an insertion rod inserted into the through hole and extending to the accommodating cavity, a stop plate arranged at the inner end of the insertion rod, and a spring, one end of the spring abuts against the stop plate, and the other end abuts against the inner wall of the main body, and the stop plates on the insertion rods in the same layer of through holes are arranged opposite to each other;

[0010] A driving assembly, comprising a rotating plate arranged between stop plates on the same layer, wherein the rotating plate comprises a first abutting portion and a second abutting portion arranged at intervals, wherein the length of the second abutting portion is greater than the length of the first abutting portion, and when the first abutting portion abuts against the stop plate, the end of the insertion rod away from the stop plate is located in the through hole, and when the second abutting portion abuts against the stop plate, the end of the insertion rod away from the stop plate is located outside the main body.

[0011] The present invention installs an insertion rod in the through hole of the rod body, and the insertion rod can extend out of the rod body into the slope soil under the action of the rotating plate, thereby interfering with the soil. Therefore, the present invention is not easy to separate from the spoil field slope under the impact of rainwater, causing the spoil field slope to become unstable.

[0012] Furthermore, the open-pit mine dump slope fixing device also includes a second fixing component, which includes an elastic bag arranged on the cone, a thermoplastic material filled in the elastic bag, and the elastic bag is arranged at an end away from the cone and tilted toward the main body. Since the thermoplastic material is solid at room temperature, the elastic bag will form a relatively hard structure. When the rod body of the present invention is inserted into the soil, the elastic bag can also be inserted into the soil to fix the position of the rod body to prevent the rod body from moving out of the slope.

[0013] Furthermore, the angle between the elastic bag and the cone is less than 90 degrees, so that at normal temperature, the elastic bag will be hooked on the slope soil to prevent it from falling out.

[0014] Furthermore, a plurality of the elastic bags are provided, and the plurality of the elastic bags are arranged in layers on the cone portion to increase the anti-falling capability of the elastic bags as much as possible.

[0015] Furthermore, the second fixing assembly also includes a heater electrically connected to the thermoplastic material, so that when the present invention needs to be recycled, the thermoplastic material can be heated to soften or melt it, thereby reducing the difficulty of pulling out the rod body.

[0016] Further, the rotating plate is an elliptical plate, two edges of the elliptical plate in the short axis direction are first abutting portions, and two edges of the elliptical plate in the long axis direction are second abutting portions.

[0017] Furthermore, the driving assembly further comprises a rotating rod connected to the center of each layer of rotating plates and a driving plate connected to the rotating rod. Thus, the position of the rotating plate can be adjusted by rotating the driving plate and the rotating rod, thereby realizing the switching of the connection between the first abutting portion, the second abutting portion and the stop plate.

[0018] Furthermore, the rod body also includes a stopper portion provided at one end of the main body away from the cone portion, and the rotating rod passes through the stopper portion and is connected to each layer of rotating plates. When the rod body is inserted into the soil on the slope, the bottom surface of the stopper portion can be close to the slope surface to protect the soil around the outer end of the rod.

[0019] Furthermore, the driving plate is located on a side of the stopper away from the main body.

[0020] Furthermore, the stopper is provided with a first plug hole, and the drive plate is provided with a second plug hole. When the second abutting portion abuts against the stopper plate, the first plug hole is directly opposite to the second plug hole, and fixing pins are inserted into the first plug hole and the second plug hole. In this way, the fixing pin can be used to lock the extended state of the plug rod to ensure stable anti-dropping.

[0021] Furthermore, the elastic bag is made of TPU material.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1) After the rod body is inserted into the slope of the spoil dump, the present invention drives the rotating plate to make its second abutment portion contact the stop plate, and the stop plate can move toward the outside of the rod body, and drive the end of the insertion rod away from the rod body to move out of the through hole and then insert into the soil on the slope to fix the rod body, which can effectively prevent the rod body from easily moving out of the slope.

[0024] 2) Since the thermoplastic material is solid at room temperature, the elastic bag forms a relatively hard structure. Therefore, the elastic bag of the present invention can also be inserted into the soil to fix the position of the rod body, further preventing the rod body from moving out of the slope.

[0025] 3) The present invention can be recycled. When the open-pit mine dump slope protection device needs to be recycled later, the rotating plate can be driven to rotate so that the first abutment portion contacts the stopper plate, and the spring can drive the insertion rod to move toward the inside of the rod body and move into the perforation, so that the rod body can be relatively easily pulled out of the soil. In addition, before pulling out the rod body, the thermoplastic material in the elastic bag can be heated by a heater to soften or melt it, thereby reducing the difficulty of pulling out the rod body.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Reference Figures 1 to 5 As shown, an embodiment of the open-pit mine dump slope fixing device of the present invention includes a rod body 1, a first fixing component 2, a driving component 3 and a second fixing component 4.

[0037] Specifically, the rod body 1 includes an integrally connected main body 11 and a cone 12 arranged at one end of the main body 11 , a receiving cavity 111 is arranged in the main body 11 , and a through hole 112 extending from the circumferential outer wall of the main body 11 to the receiving cavity 111 is opened circumferentially of the main body 11 .

[0038] The first fixing component 2 includes an insertion rod 21 inserted into the through hole 112 and extending to the accommodating cavity 111, a stop plate 22 provided at one end of the insertion rod 21 away from the circumferential outer wall of the main body 11, and a spring 23 sleeved on the insertion rod 21, and the two ends of the spring 23 respectively abut against the stop plate 22 and the circumferential inner wall of the main body 11.

[0039] The driving assembly 3 includes a rotating plate 31 for abutting against the end of the stop plate 22 away from the spring 23. The rotating plate 31 includes a first abutting portion 311 and a second abutting portion 312 that are spaced apart. When the first abutting portion 311 abuts against the stop plate 22, the end of the insertion rod 21 away from the stop plate 22 is located in the through hole 112. When the second abutting portion 312 abuts against the stop plate 22, the end of the insertion rod 21 away from the stop plate 22 is located outside the main body 11.

[0040] The second fixing assembly 4 includes an elastic bag 41 disposed on the cone 12 , a thermoplastic material 42 filled in the elastic bag 41 , and a heater 43 embedded in the cone 12 and close to the elastic bag 41 .

[0041] When the present invention is used, the rod body 1 is inserted into the corresponding position on the slope of the spoil dump, and the rod body 1 is completely immersed in the soil on the slope as much as possible. Then the rotating plate 31 is driven to rotate so that its second abutment portion 312 contacts the stop plate 22. During this process, the stop plate 22 moves toward the outside of the rod body 1 and drives the end of the insertion rod 21 away from the rod body 1 to move out of the through hole 112 and insert into the soil on the slope, thereby fixing the rod body 1 and preventing the rod body 1 from easily moving out of the slope.

[0042] Meanwhile, the thermoplastic material 42 is solid at room temperature, so that the elastic bag 41 forms a relatively hard structure. The elastic bag 41 can also be inserted into the soil to fix the position of the rod body 1 .

[0043] When the open-pit mine dump slope protection device needs to be recovered later, the rotating plate 31 is first driven to rotate so that its first abutment portion 311 contacts the stop plate 22. During this process, the spring 23 drives the stop plate 22 to move toward the inside of the rod body 1, and the stop plate 22 drives the insertion rod 21 to move into the accommodating cavity 111. The end of the insertion rod 21 located outside the rod body 1 moves into the through hole 112, so that the rod body 1 can be relatively easily pulled out of the soil. In addition, before pulling out the rod body 1, the thermoplastic material 42 in the elastic bag 41 can also be heated by the heater 43 to soften or melt it, thereby reducing the difficulty of pulling out the rod body 1.

[0044] In one embodiment, referring to Figure 5As shown, the end of the elastic bag 41 away from the cone 12 is higher than the end close to the cone 12. That is, after the rod body 1 is inserted into the soil on the slope, the elastic bag 41 tilts upward (outside the slope), and when the rod body 1 is pulled out, an inverted hook is formed between the elastic bag 41 and the cone 12, which can enhance the resistance of pulling out the rod body 1, improve the stability of the rod body 1, and improve its slope protection effect. After the open-pit mine dump slope protection device of the present invention is recovered, although the thermoplastic material 42 in the elastic bag 41 may soften or melt in some cases, it can still be assisted to restore its original shape by means of molds, extrusion equipment, etc.

[0045] In one embodiment, referring to Figure 5 As shown, a plurality of elastic bags 41 are provided and are disposed around the cone portion 12 to enhance the fixing effect of the elastic bags 41 on the rod body 1 .

[0046] Furthermore, the elastic bags 41 are arranged in layers along the central axis of the cone 12. Preferably, the elastic bags 41 can be arranged in two layers.

[0047] In one embodiment, in order to simplify the structure of the rotating plate 31, reduce its manufacturing cost, and improve the working stability, the rotating plate 31 is constructed as an elliptical plate, and the two edges of the elliptical plate in the short axis direction are the first abutment parts 311, and the two edges of the elliptical plate in the long axis direction are the second abutment parts 312. The periphery of the elliptical plate is relatively smooth and continuous, which can reduce the friction between itself and the stop plate 22. When the rod body 1 is inserted into the soil on the slope, it is easier for the operator to drive the rotating plate 31 to rotate.

[0048] In one embodiment, referring to Figures 1 to 3 As shown, the insertion rods 21 are symmetrically arranged on both sides of the rotating plate 31, and the insertion rods 21 can also be arranged in layers along the axial direction of the rotating plate 31 to maximize the stability of the rod body 1.

[0049] In one embodiment, referring to Figure 2 , Figure 3 As shown, in order to facilitate the operator to drive the rotating plate 31 to rotate, the driving assembly 3 also includes a rotating rod 32 connected to the center of the rotating plate 31 and a driving plate 33 connected to the rotating rod 32. Since the rotating plate 31 is installed in the accommodating cavity 111 perpendicular to the rod body 11, the rotating rod 32 can be rotated by rotating the rotating rod 32 connected to the rotating plate 31 or the driving plate 33 connected to the rotating rod 32, so that the contact switching between the first abutting portion 311 or the second abutting portion 312 of the rotating rod 32 and the stop plate 22 can be achieved.

[0050] Furthermore, the rod body 1 further comprises a stopper 13 disposed at one end of the main body 11 away from the cone 12, the rotating rod 32 passes through the stopper 13, the driving plate 33 is located at a side of the stopper 13 away from the main body 11, and the driving plate 33 can appropriately protrude from the stopper 13. When the rod body 1 is inserted into the soil on the slope, the bottom surface of the stopper 13 can be close to the surface of the slope to protect the soil around the outer end of the rod body 1.

[0051] In one embodiment, referring to Figure 4 As shown, the stopper 13 is provided with a first insertion hole 131, and the driving plate 33 is provided with a second insertion hole 331. When the second abutting portion 312 abuts against the stopper plate 22, the first insertion hole 131 is directly opposite to the second insertion hole 331, and the first insertion hole 131 and the second insertion hole 331 are inserted with a fixing pin 34, thereby locking the position of the rotating plate 31, and the insertion rod 21 remains in a state of extending out of the rod body 1. When the rod body 1 is not inserted into the soil on the slope, the fixing pin 34 is separated from the first insertion hole 131 and the second insertion hole 331, and the first insertion hole 131 and the second insertion hole 331 are not aligned. At this time, the first abutting portion 311 of the rotating plate 31 contacts the stopper plate 22. When the second abutment portion 312 of the rotating plate 31 contacts the stop plate 22, the end of the insertion rod 21 away from the rotating plate 31 has been pushed out of the through hole 112 to the maximum extent, the second insertion hole 331 is aligned with the first insertion hole 131, and the fixing pin 34 is inserted into the first insertion hole 131 and the second insertion hole 331, so that the position of the insertion rod 21 can be locked.

[0052] Preferably, the elastic bag 41 is made of TPU material.

[0053] The above is only a specific implementation scheme of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the art can make many possible changes and modifications to the technical scheme of the present invention by using the technical content disclosed above without departing from the scope of the technical scheme of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical scheme of the present invention should fall within the protection scope of the technical scheme of the present invention.
