Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology in mining, and in particular to a lightning protection system for open-pit alkali rock mines. Background Technology

[0002] Due to their unique geographical environment and altitude, open-pit mines make equipment such as electric shovels, electric backhoes, down-the-hole drills, and electric mining cars highly susceptible to lightning strikes. Therefore, for structures or the aforementioned equipment requiring special protection, independent lightning rods or lightning protection networks are often installed. When laying lightning protection networks, supports are needed, and the flatness of these supports is crucial to the stability of the network. However, due to the complex mining environment, there may be uneven terrain and varying soil hardness. Existing supports cannot be adjusted in angle and height according to the terrain, making it difficult to maintain overall consistency and flatness. Uneven installation of supports can cause the lightning protection network to deform or shift due to uneven stress, thus affecting its lightning protection effectiveness. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an open-pit alkali rock mine lightning protection system to solve the problem that existing lightning protection network supports cannot be adjusted according to terrain conditions, making it difficult to maintain their installation flatness.

[0004] This utility model is implemented as follows:

[0005] An open-pit alkali rock mine lightning protection system includes a lightning rod and a lightning protection network. The lightning rod is installed close to the equipment, and the lightning protection network is erected above the equipment or building by a support frame. The support frame includes a base plate, a support sleeve is rotatably installed on the top of the base plate, a support column is slidably connected inside the support sleeve, and a clamping component for clamping the lightning protection wire is connected to the outside of the support column.

[0006] Furthermore, a first lug is fixedly provided on the top of the base plate, and the first lug is rotatably connected to the lower part of the support sleeve through a first rotating shaft.

[0007] Furthermore, a second lug is provided on the top of the base plate, and a third lug is provided on the support sleeve. The first lug and the second lug are connected by an adjustment assembly.

[0008] Furthermore, the adjustment assembly includes a first lead screw and a second lead screw with opposite rotation directions. One end of the first lead screw is rotatably connected to the second lug via a second rotating shaft, and one end of the second lead screw is rotatably connected to the third lug via a third rotating shaft. The other ends of the first lead screw and the other ends of the second lead screw are connected via a positive and negative threaded lead screw sleeve.

[0009] Furthermore, a through hole is provided in the middle of the positive and negative threaded screw sleeve, and the through hole extends radially through the positive and negative threaded screw sleeve.

[0010] Furthermore, there are two clamping components, which are located on both sides of the support column and are vertically arranged.

[0011] Furthermore, the clamping assembly includes a cross brace and a first clamping block. One side of the cross brace is fixedly connected to a support column, and a sliding sleeve is slidably fitted on the other side. One end of the first clamping block is fixedly connected to the sliding sleeve, and the other end is slidably connected to a second clamping block.

[0012] Furthermore, two third lead screws are fixedly connected to the other end of the first clamping block, and the second clamping block is slidably sleeved on the outside of the two third lead screws. Each third lead screw has a nut threadedly connected to its outside, and the nut abuts against the outside of the second clamping block.

[0013] Furthermore, V-shaped notches are provided on the opposite sides of the first clamping block and the second clamping block, and the two V-shaped notches form a space for the lightning protection wire to pass through.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] like Figures 1-3 The present invention relates to an open-pit alkali rock mine lightning protection system, which includes a lightning rod (not shown in the figure) and a lightning protection network. The lightning rod is installed close to the equipment, and the lightning protection network is erected above the equipment or building by a bracket. The bracket includes a base plate 1, a support sleeve 2 is rotatably installed on the top of the base plate 1, a support column 3 is slidably connected inside the support sleeve 2, and a clamping component 4 for clamping the lightning protection wire is connected to the outside of the support column 3.

[0024] In this embodiment, the lightning rod is placed close to the equipment. Specifically, electric shovels, electric backhoes, down-the-hole drills, and electric mining cars are highly susceptible to lightning strikes. Individual lightning rods can be placed near them, or a single lightning rod can be placed around several pieces of equipment. There are no restrictions here; the placement can be based on the requirements.

[0025] The lightning protection network is erected above important equipment or buildings by a support frame. The support frame includes a base plate 1 with connection holes for anchor bolts or expansion bolts to pass through, so as to securely connect the base plate 1 to the ground or the roof of the building. The connection between the base plate 1 and the ground or the roof of the building is existing technology and will not be described in detail here.

[0026] like Figure 1As shown, a first lug 11 is fixedly provided on the top of the base plate 1, and the first lug 11 is rotatably connected to the lower part of the support sleeve 2 via a first rotating shaft 12. The first rotating shaft 12 is horizontally arranged, passes through the first lug 11 and is fixedly connected to it. At the same time, the first rotating shaft 12 passes through the lower part of the support sleeve 2, and the support sleeve 2 is rotatably connected to the first rotating shaft 12. A second lug 13 is also provided on the top of the base plate 1, and a third lug 21 is provided on the support sleeve 2. The first lug 11 and the second lug 13 are connected by an adjusting assembly 5. The adjusting assembly 5 includes a first lead screw 51 and a second lead screw 52 with opposite rotation directions. One end of the first lead screw 51 is rotatably connected to the second lug 13 via a second rotating shaft 53, and one end of the second lead screw 52 is rotatably connected to the third lug 21 via a third rotating shaft 54. The other end of the first lead screw 51 and the other end of the second lead screw 52 are connected by a positive and negative threaded lead screw sleeve 55. The inner wall of the reversible threaded rod sleeve 55 consists of two threaded sections with opposite directions of rotation. These two threaded sections are respectively configured to correspond to the rotation directions of the first threaded rod 51 and the second threaded rod 52 on the corresponding sides, for threaded connection. A through hole (not shown in the figure) is provided in the middle of the reversible threaded rod sleeve 55, extending radially through it. This design is advantageous when the mine terrain is complex and the ground is sloping. Figure 3 As shown, when the base plate 1 is tilted, in order to ensure that the support column 3 and the support sleeve 2 are both in a vertical state, any rod that meets the specifications used on site is inserted into the through hole of the positive and negative threaded rod sleeve 55. When the positive and negative threaded rod sleeve 55 is rotated, the first threaded rod 51 and the second threaded rod 52 move closer or further away at the same time, which drives the support column 3 and the support sleeve 2 to rotate along the axial direction of the first rotating shaft 12 until the support column 3 and the support sleeve 2 are in a vertical state. This ensures that each support column 3 and support sleeve 2 in different terrain conditions can maintain a vertical state and ensures the consistency of the bracket installation.

[0027] A support column 3 is slidably connected inside the support sleeve 2. In this embodiment, the support column 3 passes through the support sleeve 2 and can reciprocate along its length. Two screws 22 are threadedly connected to the support sleeve 2, and the two screws 22 are symmetrically arranged on two opposite sides of the support sleeve 2. One end of each screw 22 abuts against the support column 3, that is, the end of each screw 22 closest to the support column 3 abuts against the outer wall of the corresponding side of the support column 3. When one end of the screw 22 abuts against the side wall of the support column 3, the support column 3 and the support sleeve 2 are locked and cannot slide. When one end of the screw 22 no longer abuts against the side wall of the support column 3, the support column 3 can slide up and down within the support sleeve 2 to ensure that the tops of each support column 3 are flush and consistent.

[0028] Two clamping components 4 are connected to the outer side of the support column 3 to hold the lightning protection wires. The two clamping components 4 are located on opposite sides of the support column 3 and are vertically arranged. The two clamping components 4 are perpendicular to each other to clamp the lightning protection wires in two directions within the lightning protection network. Of course, if the lightning protection wires in the lightning protection network only run in one direction, the clamping component 4 for the other direction can be removed, depending on actual needs.

[0029] The clamping assembly 4 includes a cross brace 41 and a first clamping block 42. One side of the cross brace 41 is fixedly connected to the support column 3, and the other side is slidably fitted with a sliding sleeve 43. The sliding sleeve 43 has a C-shaped structure and is slidably fitted on the outside of the cross brace 41. A screw 22 is threadedly connected to the top wall of the sliding sleeve 43, and one end of the screw 22 abuts against or separates from the cross brace 41. When the screw 22 is rotated and one end of the screw 22 abuts against the cross brace 41, the sliding sleeve 43 cannot slide on the cross brace 41, and at this time the sliding sleeve 43 and the cross brace 41 are in a tight connection state; when one end of the screw 22 separates from the cross brace 41, the sliding sleeve 43 can slide on the cross brace 41, and the sliding sleeve 43 can be removed from the cross brace 41. One end of the first clamping block 42 is fixedly connected to the sliding sleeve 43, and the other end is slidably connected to a second clamping block 44. Two third lead screws 45 are fixedly connected to the other end of the first clamping block 42. The second clamping block 44 has a U-shaped structure and is sleeved on the outside of the first clamping block 42. The two third lead screws 45 are located inside the U-shaped cavity of the second clamping block 44, that is, the second clamping block 44 is slidably sleeved on the outside of the two third lead screws 45. A nut 46 is threadedly connected to the outside of each third lead screw 45, and the two nuts 46 abut against the outside of the second clamping block 44. In this embodiment, the side of the second clamping block 44 closest to the first clamping block 42 is defined as the inner side, and the side opposite to the inner side is defined as the outer side. V-shaped notches are opened on the opposite sides of the first clamping block 42 and the second clamping block 44, and the two V-shaped notches enclose a receiving space 47 for the lightning protection wire to pass through. The second clamping block 44 is slidably connected to the first clamping block 42. By adjusting the distance between the two, the size of the accommodating space 47 can be adjusted to accommodate the passage of lightning protection wires of various diameters, thereby clamping different types of lightning protection wires and improving the versatility and adaptability of the clamping assembly 4.

[0030] In use, the lightning protection system for open-pit alkali rock mines of this utility model is fastened between the base plate 1 and the precast foundation on the ground using anchor bolts or expansion bolts. Rotating the positive and negative threaded rod sleeve 55 causes the first threaded rod 51 and the second threaded rod 52 to move closer or further apart. During this movement, the first threaded rod 51 and the second threaded rod 52 drive the support column 3 to rotate axially along the first rotating shaft 12 until the support column 3 and the support sleeve 2 rotate to a vertical position. Then, rotating the screws 22 on the support sleeve 2 so that their end faces no longer abut against the side wall of the support column 3, allows the support column 3 to move freely within the support sleeve 2. Slide the inner part of the support column 3 to adjust its position so that its height meets the installation requirements and is flush with the other support columns 3. Then rotate the screws 22 on the support sleeve 2 in the opposite direction so that their end faces abut against the side wall of the support column 3 again, and the support column 3 and the support sleeve 2 are in a tightly fixed state. Loosen the screws 22 on the outside of the second clamping block 44 and pass the lightning protection wire through the receiving space 47 enclosed by the first clamping block 42 and the second clamping block 44. Then rotate the screws 22 in the opposite direction. During the rotation of the screws 22, the second clamping block 44 is moved closer to the first clamping block 42 until it works together with the first clamping block 42 to clamp the lightning protection wire.

[0031] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Anyone skilled in the art should know that any easily conceivable variations or modifications are possible under the technical spirit of this utility model and are covered by the patent claims of this utility model.
