[0044] The present invention provides the following embodiments

[0045] Example 1

[0046] The embodiment of the present invention provides a method for preventing rainwater erosion and geological displacement settlement when laying cables on slopes, such as Figure 1-7 As shown, it includes: S1: excavating a cable laying trench and installing a plurality of anchor rods at the bottom of the cable laying trench;

[0047] S2: Lay pre-coated steel cables in the cable laying trench and connect the anchor rods with each other through the pre-coated steel cables;

[0048] S3: Install rigid fixing fixtures on the first section of anchor rods, and install flexible fixing fixtures on the remaining anchor rods;

[0049] S4: adjusting the axle structure 4 so that the cable laying device adapts to the width of the cable laying groove, and laying the cable in the cable laying groove. The cable is installed in the rigid fixing fixture and the flexible fixing fixture. After laying a certain length of cable, the cable laying device 2 is stationary on the slope of the hilly terrain through the ratchet resistance mechanism 5 until laying again;

[0050] S5: After laying the cable protection plate and cable warning tape on the cable, backfill the cable laying trench;

[0051] S6: After laying the cable on the slope, set up drainage ditches at the top and bottom of the slope.

[0052] The working principle and beneficial effects of the above technical solution are as follows: after excavating the cable laying trench, a number of anchor rods are inserted into the cable laying trench so that the anchor rods and the foundation are connected as a whole, and then the anchor rods are connected in series as a whole by pre-laying steel cables, and a rigid fixing fixture is installed on the first section of the anchor rods at the top of the slope, and a flexible fixing fixture is installed on the remaining anchor rods, and then the cable 66 is laid by the cable laying device 2. The cable laying device 2 adjusts the width through the axle structure 4 to adapt to cable laying trenches of different widths. After laying a certain length of cable 66, the cable laying device 2 is stationed on the slope surface through the ratchet resistance mechanism 5, and the operator places the laid cable 66 into the rigid fixing fixture and the flexible fixing fixture, and then repeats the laying of the cable 66 until the entire section of the cable 66 on the slope is laid, backfills the cable laying trench, and excavates drainage ditches at the top and bottom of the slope;

[0053] The present invention utilizes a cable laying device 2 to lay cables. This design can effectively reduce the labor intensity of operators during the laying of the cables 66. The cables 66 can be mechanically transported to the top of the slope and laid semi-automatically, thereby improving the efficiency of laying the cables 66. The design of the axle structure 4 can be adjusted and adapted according to the width of the cable laying groove, thereby improving the adaptability and flexibility of the cable laying device 2. At the same time, the design of the ratchet resistance mechanism 5 can avoid the influence of the slope of hilly areas on the transmission structure of the cable laying device 2, thereby avoiding the transmission structure being always under a large load under the action of gravity and causing metal fatigue.

[0054] Example 2

[0055] Based on Example 1, the cable laying device 2 includes a walking component 3, a storage component 6 is installed above the walking component 3, a laying component 8 is provided at the front end of the walking component 3, the laying component 8 and the storage component 6 cooperate with each other, and the cable laying device 2 also includes a laying monitoring component.

[0056] The working principle and beneficial effects of the above technical solution are as follows: when the cable is being laid, the cable laying device 2 is driven by the walking component 3 to lay the cable 66 above the cable laying groove, and the storage component 6 releases the cable 66 by rotating. When the cable 66 is released, a new cable 66 is replaced, and the laying component 8 pulls the cable 66 to lay it in the cable laying groove, and the laying monitoring component monitors the tension of the cable during the cable laying process;

[0057] The cable laying device 2 of the present invention is driven by the walking component 3. This design can improve the transportation and laying efficiency of the cable 66 during the laying process. The design of the storage component 6 can store longer cables 66 for use in the laying process, and quickly replace and add new cables 66 after the cables 66 are laid. The laying component 8 ensures the straightness of the cable 66 in the cable laying groove, avoiding the bending of the cable 66 during laying and the need for later adjustment. The design of the laying monitoring component ensures the tension balance of the cable 66 during the laying process, avoiding excessive tension on the cable 66 and damage to its structure.

[0058] Example 3

[0059] On the basis of Example 1, the walking component 3 includes a walking frame 31, on which a driving motor 32 and a reduction differential box 33 are installed, the output end of the driving motor 32 is connected to the input end of the reduction differential box 33, a wheel axle structure 4 is provided below the walking frame 31, the output end of the reduction differential box 33 is connected to the wheel axle structure 4, four groups of shock absorbers 34 are hingedly connected below the walking frame 31, and the four groups of shock absorbers 34 correspond one-to-one to the wheel axle structure 4 below, and a storage component 6 is installed above the walking frame 31.

[0060] The wheel axle structure 4 includes a driving wheel axle 41 and a driven wheel axle 42, and the driving wheel axle 41 and the driven wheel axle 42 are rotatably connected with the shock absorber 34. The driving wheel axle 41 passes through and is installed at the output end of the reduction differential case 33. Both ends of the driving wheel axle 41 and the driven wheel axle 42 are provided with a slide cylinder 43 and a pulley 44. The slide cylinder 43 is connected with a telescopic column 45 by a sliding key, and the other end of the telescopic column 45 is connected to the pawl resistance mechanism 5. Two folding plates 46 are symmetrically arranged between the pulley 44 and the pawl resistance mechanism 5. Both ends of the two folding plates 46 are respectively hinged to the side of the pulley 44 and the pawl resistance mechanism 5, and a telescopic rod 47 is fixedly connected between the two folding plates 46.

[0061] The pawl resistance mechanism 5 includes a blocking disc 51, which is fixedly connected to the telescopic column 45, and a ratchet 52 is fixedly connected inside the blocking disc 51. A wheel axle 53 passes through and is rotatably connected on the other side of the blocking disc 51. A wheel disc 54 is fixedly connected to one end of the wheel axle 53, and a wheel 55 is fixedly connected to the other end of the wheel axle 53. The wheel disc 54 slides relative to the blocking disc 51, and sliding grooves 56 are symmetrically provided on the wheel disc 54. A pawl 57 is slidably connected in the sliding grooves 56. The pawl 57 is meshed with the ratchet 52, and a compression elastic member 58 is provided between the pawl 57 and the wheel disc 54. An unlocking rod 59 is fixedly connected to the inner wall of the blocking disc 51, and the unlocking rod 59 slides relative to the ramp 510 on the pawl 57.

[0062] The beneficial effects of the above technical solution are as follows: when the cable laying device 2 is laying the cable 66, the walking assembly 3 adjusts the width of the wheel axle structure 4 according to the cable laying groove, and the telescopic rod 47 is extended and retracted, driving the folding plates 46 at both ends of the telescopic rod 47 to move away or closer. When the wheel axle structure 4 needs to be widened, the telescopic rod 47 makes the folding plates 46 move closer to each other, and the folding plates 46 then push the telescopic column 45 to slide in the slide cylinder 43, thereby making the wheel 55 slide relative to the ground until it stops after a certain length. When the wheel axle structure 4 needs to be narrowed, the telescopic rod 47 makes the folding plates 46 move away from each other, and the telescopic column 45 repeats the above operation. After the width of the wheel axle structure 4 is adjusted, the walking assembly 3 travels upward along the cable laying groove from the bottom of the hill, and the drive motor 32 transmits power to the drive wheel axle 41 through the reduction differential box 33. The drive wheel axle 41 drives the wheel 55 to rotate forward, thereby making the wheel 55 on the driven wheel axle 42 5 rotates forward until the cable laying device 2 moves to the specified position, the storage assembly 6 releases the cable 66, the driving motor 32 reverses to make the traveling frame 31 move backward downward, and stops after laying a certain length. At this time, the pawl 57 and the ratchet 52 are meshed with each other under the action of the compression elastic member 58, and the wheel 55 cannot drive the wheel shaft 53 and the wheel disc 54 to rotate. When the cable laying device 2 is moving, the driving wheel shaft 41 drives the telescopic column 45 to rotate, and then drives the blocking disc 51 to rotate. The rotation of the blocking disc 51 causes the unlocking rod 59 to slide in the ramp 510. Under the action of pressure, the unlocking rod 59 pushes the pawl 57 to slide toward the center along the slide groove 56. The pawl 57 and the ratchet 52 are unlocked, and the unlocking rod 59 continues to cooperate with the slide groove 56 to push the wheel disc 54 to rotate, thereby causing the wheel 55 to rotate a certain angle, driving the whole forward. When the driving wheel shaft 41 stops rotating, the pawl 57 is reset under the action of the compression elastic member 58;

[0063] The present invention utilizes a driving motor 32 to drive the wheel axle structure 4 to drive the traveling frame 31 to travel, and connects the wheel axle structure 4 and the traveling frame 31 through a shock absorber 34. This design can reduce the vibration of the cable laying device 2 caused by the slope of the hilly area, and ensure the stability of the cable laying device 2 when traveling;

[0064] The wheel axle structure 4 can adjust the wheelbase length by means of the telescopic rod 47 and the folding plate 46. This design enables the cable laying device 2 to lay the cable 66 when facing cable laying grooves of different widths. The design of the folding plate 46 and the telescopic rod 47 makes the structure more compact, thereby reducing the volume of the wheel axle structure 4.

[0065] The pawl resistance mechanism 5 can prevent the wheel 55 from rotating by engaging the pawl 57 with the ratchet 52, ensuring that the cable laying device 2 can move only when the driving wheel shaft 41 and the driven wheel shaft 42 rotate. This design can avoid the load of gravity on the transmission structure of the cable laying device 2 on the slope, thereby extending the life of the transmission structure of the cable laying device 2.

[0066] Example 4

[0067] On the basis of Example 1, the storage assembly 6 includes a rotating frame 61, and the two rotating frames 61 are symmetrically bolted on the walking frame 31. The tops of the two rotating frames 61 are rotatably connected to the rotating shaft 62, and the rotating shaft 62 is provided with a U-shaped groove 63. The U-shaped groove 63 is rotatably connected to the cable reel 64, and a fixing pin 65 passes through and is slidably connected to the rotating shaft 62. The fixing pin 65 cooperates with the cable reel 64, and a cable 66 is wound in the cable reel 64. Friction belts 67 are installed on the outer rings of both sides of the cable reel 64, and a follow-up transmission structure 7 is provided on both sides of the cable reel 64.

[0068] The follower transmission structure 7 includes a follower wheel 71, and the two follower wheels 71 are respectively arranged above the two sides of the driven wheel shaft 42. The follower wheel 71 is connected to the pulley 44 through a belt 72. The follower wheel 71 is installed on a follower rotating shaft 73, and the follower rotating shaft 73 is rotatably connected to the rotating shaft seat 74. The rotating shaft seat 74 is fixedly installed on the traveling frame 31. The other end of the follower rotating shaft 73 is installed with a fitting friction wheel 75, and the fitting friction wheel 75 and the friction belt 67 slide relatively.

[0069] The beneficial effects of the above technical solution are as follows: when laying cables, the pulley 44 drives the follower wheel 71 to rotate through the belt 72, and the follower wheel 71 drives the follower shaft 73 and the fitting friction wheel 75 to rotate, and the fitting friction wheel 75 and the friction belt 67 on the cable drum 64 are fitted and driven, and the cable drum 64 and the shaft 62 rotate on the rotating frame 61, so that the cable 66 on the cable drum 64 is released. When the cable 66 on the cable drum 64 is released, the fixing pin 65 on the shaft 62 is taken out, and the cable drum 64 is released from the U-shaped groove 63 of the shaft 62, and a new cable drum 64 is replaced;

[0070] The present invention utilizes a cable drum 64 to store a cable 66 and fixes it in a U-shaped groove 63 of a rotating shaft 62 through a fixing pin 65. This design can ensure that the cable drum 64 rotates and can also replace the cable drum 64 in a timely manner, thereby improving the efficiency of laying the cable 66. At the same time, the cable drum 64 adopts a contact friction wheel 75 and a follower wheel 71 to drive the pulley 44. This design can make the rotation of the cable drum 64 follow the rotation of the wheel 55, thereby ensuring that the release length of the cable 66 is consistent with the travel distance of the cable laying device 2, thereby avoiding the dragging of the cable 66 caused by the unstable release length of the cable 66.

[0071] Example 5

[0072] On the basis of Example 1, the laying assembly 8 includes a chain conveyor belt 81, which is rotatably connected to a laying frame 82. A lead screw 83 is threadedly connected to the top of the laying frame 82, a handle 84 is fixedly connected to the top of the lead screw 83, and a pressing frame 85 is fixedly connected to the bottom of the lead screw 83. A plurality of rollers 86 rotate inside the pressing frame 85. A front laying roller 87 is provided in the forward direction of the chain conveyor belt 81, and the front laying roller 87 is rotatably installed at the front end of the traveling frame 31.

[0073] The beneficial effects of the above technical solution are as follows: during the laying process of the cable 66, after the cable 66 is released from the cable drum 64, the cable 66 is placed above the chain plate conveyor belt 81, the rotary handle 84 is turned to make the lead screw 83 rotate and descend, and the roller 86 on the pressing frame 85 squeezes the cable 66, and then the chain plate conveyor belt 81 is started to drive the cable 66 forward, and the synchronous roller 86 rotates, and the cable 66 passes through the front laying roller 87 and falls into the cable laying groove;

[0074] The present invention utilizes the chain conveyor belt 81 and the roller 86 of the pressing frame 85 to drive the cable 66 forward. This design can ensure that the cable 66 moves forward in a straight state, avoid the cable 66 swinging during the laying process, and cause the cable 66 to be bent during laying, thereby reducing the laying difficulty for the operator. At the same time, the design of the handle 84 and the lead screw 83 enables the laying assembly 8 to adapt to cables 66 of any size, and the design of the front laying roller 87 ensures that the cable 66 will not bend due to gravity before falling into the cable laying groove.

[0087] Step 2: The data processing module compares the tension coefficient T of the cable 66 c and T c0 :

[0088] When T c >T c0 When based on T c Calculate the cable adjustment parameter M d , when T c ≤T c0 No processing when:

[0089] Where T c0 is the tension reference coefficient of cable 66, M d is the cable adjustment coefficient, K is the tension influence range coefficient;

[0090] Step 3: The control module controls the execution module to alarm and display the d The cable drum 64 is adjusted to a certain number of rotations.

[0091] The beneficial effects of the above technical solution are as follows: when the cable laying device 2 is laying the cable 66, the driven wheel shaft 42 and the cable drum 64 may occasionally slip during the transmission process, which may cause a difference between the travel distance of the wheel 55 and the length of the cable 66 released from the cable drum 64. When the cable 66 is initially laid for a short length, the cable 66 can make up for the difference by sliding. However, when the cable 66 is laid for a long length, the friction between the cable 66 and the cable laying groove may cause the cable 66 to be unable to slide. The combined force of this friction and the tension caused by the difference in the length of the released cable may cause deformation of the cable 66. When the two accumulate to a certain extent, the cable 66 may be destructively deformed. Therefore, the cable 66 needs to be regularly adjusted within a controllable range.

[0092] The present invention utilizes a control module, a data processing module, a detection module and an execution module to monitor the laying process of the cable 66. This design can prevent the cable 66 from undergoing destructive deformation during the laying process, thereby ensuring the quality of the laying of the cable 66, avoiding subsequent rework, and ensuring the stability of the laying of the cable 66.

[0093] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
