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

[0023] 1. The present invention controls the lifting ring to rise or fall by means of a screw rod, so that the inner mounting frame and the outer mounting frame move up and down together.

[0024] 2. The friction force generated by the friction plate prevents the winding drum from rotating through the abutment structure between the friction plate and the side wall of the winding drum. When the winding drum is at the lowest point, it is the installation position of the winding drum. The winding drum is prevented from rotating to facilitate installation. When the winding drum is located at a certain height below, under the elastic force of the first spring, the friction plate is still in abutment with the winding drum and prevents rotation, which is convenient for transportation of the winding drum and the laying device and prevents danger caused by the rotation of the winding drum during transportation.

[0025] 3. Through the abutment structure of the rotating roller and the lifting roller, when the rotating roller rotates, the two rotate in opposite directions, and the friction between the two drives the cable to be pulled on the winding drum, and the rubber pad and its convex block structure ensure that the cable can be pulled without pinching the cable, thereby effectively pulling and laying the cable on the winding drum.

DETAILED DESCRIPTION

[0040] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0041] See also Figures 1 to 13 The present invention provides a technical solution: a transmission line cable laying device, comprising: a mobile vehicle 1, a handle 11 is provided above one end of the mobile vehicle 1, and a protective component 2 is provided on the upper side of the mobile vehicle 1 facing the handle 11;

[0042] The structure of the handle 11 facilitates the moving vehicle 1 to move horizontally.

[0043] A lifting ring 3, the lifting ring 3 is arranged above the protection component 2, the lifting ring 3 is vertically slidably connected to the protection component 2, and first positioning columns 35 are driven on both sides of the lifting ring 3, and the first positioning columns 35 are horizontally slidably connected to the lifting ring 3;

[0044] By controlling the lifting ring 3 to move up and down inside the protective component 2, the first positioning column 35 is driven to slide up and down. After the first positioning column 35 is installed on the winding drum 9, the lifting control of the winding drum 9 is realized.

[0045] An inner mounting frame 4, wherein the inner mounting frame 4 is arranged on both sides of the lifting ring 3, the outer side of the first positioning column 35 is arranged in the inner mounting frame 4, and an outer mounting frame 5 is arranged on the outer side of the inner mounting frame 4;

[0046] The inner mounting frame 4 cooperates with the first positioning column 35 to install and fix the inner side of the winding drum 9, and through the sliding structure of the first positioning column 35 and the inner mounting frame 4, it is convenient to install the winding drum 9 after the first positioning column 35 is retracted to the inner mounting frame 4.

[0047] A second positioning column 51 is installed inside the outer mounting frame 5, and a winding drum 9 is arranged inside the inner mounting frame 4 and the outer mounting frame 5. The first positioning column 35 and the second positioning column 51 together rotatably install the winding drum 9 inside the inner mounting frame 4 and the outer mounting frame 5;

[0048] The outer mounting frame 5 and the second positioning column 51 are mounted on the outer side of the winding drum 9 so that the winding drum 9 always remains horizontal during the process of the winding drum 9 being moved by the inner mounting frame 4 and the outer mounting frame 5 moving up and down.

[0049] The winding drum 9 is arranged above the protective component 2, and a friction plate 22 is arranged above the protective component 2. The side walls of the winding drum 9 abut against the upper surface of the friction plate 22, and the friction plate 22 prevents the winding drum 9 from rotating.

[0050] After the inner mounting frame 4 and the outer mounting frame 5 drive the winding drum 9 to descend to the lowest point, the friction plate 22 abuts against the side wall of the winding drum 9. The strong friction force generated by the friction plate 22 prevents the winding drum 9 from rotating, thereby preventing the winding drum 9 from rotating due to shaking when the mobile vehicle 1 drives the winding drum 9 to move, thereby causing unstable transportation.

[0051] The portion of the mobile vehicle 1 below the handle 11 is set as a hypotenuse, and the friction plate 22 is fixedly connected with a ramp plate 21 on one side of the hypotenuse of the mobile vehicle 1, and the ramp plate 21 is continuous with the hypotenuse of the mobile vehicle 1. The protective component 2 and the friction plate 22 are each provided with two groups, and the friction plate 22 is vertically slidably connected to the protective component 2. A first spring 23 is provided below the friction plate 22, and the upper end of the first spring 23 is fixedly connected to the bottom of the friction plate 22, and the other end of the first spring 23 is fixedly connected to the inner wall of the protective component 2. A plurality of telescopic rods 24 are provided around the first spring 23, and the two ends of the telescopic rods 24 are respectively fixedly connected to the friction plate 22 and the inner wall of the protective component 2.

[0052] The continuous structure between the oblique side of the mobile vehicle 1 and the ramp plate 21 facilitates the pushing of the winding drum 9 from the oblique side of the mobile vehicle 1 to the top thereof, and facilitates the installation of the winding drum 9. Under the elastic force of the first spring 23, the friction plate 22 always has a tendency to move upward, so that when the winding drum 9 is at the lowest point, the friction plate 22 prevents the winding drum 9 from rotating, which facilitates the installation of the winding drum 9 by the inner mounting frame 4 and the outer mounting frame 5. When the winding drum 9 rises up to a certain distance, the friction plate 22 can still abut against the winding drum 9, that is, after the inner mounting frame 4 and the outer mounting frame 5 fix the winding drum 9, the winding drum 9 still does not rotate when in a low position, which facilitates the transportation of the winding drum 9 by the mobile vehicle 1. The maximum rising distance of the friction plate 22 is limited by the structure of the telescopic rod 24, so that after the winding drum 9 is raised to the highest point, the friction plate 22 is separated from the winding drum 9, ensuring that the winding drum 9 can rotate to release the wire.

[0053] A fixing frame 25 is provided below the two groups of the ramp plates 21, and connecting rods 26 are respectively installed on both sides of the upper side of the fixing frame 25, and the outer ends of the connecting rods 26 are fixedly connected to the ramp plates 21 on both sides. A plurality of limit blocks 27 are fixedly connected to the side walls of the fixing frame 25, and the limit blocks 27 are vertically and evenly distributed on the fixing frame 25. The limit blocks 27 are arranged in a right triangle, and the right-angled sides of the limit blocks 27 are located below them.

[0054] Through the structure of the fixing frame 25 and the connecting rod 26, the two groups of friction plates 22 and the ramp plate 21 are kept rising or falling synchronously.

[0055] A locking mechanism 8 is provided on one side of the fixing frame 25, and the locking mechanism 8 is installed on the moving vehicle 1. The locking mechanism 8 is slidably connected with a clamping column 81 toward one side of the fixing frame 25, and the end of the clamping column 81 abuts against the limit block 27, and the clamping column 81 is clamped with the right-angled side of the limit block 27, and the clamping column 81 is slidably connected with the hypotenuse of the limit block 27. A fourth spring 82 is provided on the side of the clamping column 81 toward the locking mechanism 8, and the two ends of the fourth spring 82 are respectively fixedly connected to the inner wall of the locking mechanism 8 and the end of the clamping column 81, and the end of the clamping column 81 is also fixedly connected to a connecting rope 83, the other side of the connecting rope 83 passes through the locking mechanism 8, and the end of the connecting rope 83 is fixedly connected to a pulling block 84.

[0056] Under the elastic force of the fourth spring 82, the clamping column 81 always tends to slide toward the fixing frame 25, that is, the end of the clamping column 81 is always stuck in the gap between the limit blocks 27. When the fixing frame 25 follows the rise of the ramp plate 21, the hypotenuse of the limit block 27 contacts the clamping column 81 and squeezes the clamping column 81 to shrink. When the limit block 27 passes the clamping column 81 upward, the clamping column 81 pops out again, so that when the fixing frame 25 moves upward, the clamping column 81 will not prevent the fixing frame 25 from moving. When the right-angled side of the limit block 27 contacts the clamping column 81, the fixing frame 25 cannot slide downward due to the clamping connection between the right-angled side of the limit block 27 and the clamping column 81, that is, it is prevented that the friction plate 22 can still slide downward after abutting against the winding drum 9, resulting in unstable anti-rotation effect on the winding drum 9, and after the cable on the winding drum 9 is transported, the pull block 84 is pulled outward, so that the connecting rope 83 drives the clamping column 81 to retract into the locking mechanism 8, and the fixing frame 25 can slide downward to the lowest point.

[0057] The lifting ring 3 is provided on the upper inner side of the protection component 2, and the lower part of the lifting ring 3 is fixedly connected to the upper end of the lifting column 32, and the lower part of the lifting column 32 is sleeved on the screw rod 33, and the inner wall of the lifting column 32 is threadedly connected to the screw rod 33, and the lower end of the screw rod 33 is rotatably installed on the moving vehicle 1, and the screw rod 33 is connected to the motor in the moving vehicle 1 through an axis transmission, and a bidirectional screw rod 34 is rotatably installed in the lifting ring 3, and a gear 31 is fixedly connected to the middle outer wall of the bidirectional screw rod 34, and a rack 12 is provided below the gear 31, and the rack 12 is fixedly installed on the moving vehicle 1, and the gear 31 is meshed with the rack 12 for transmission.

[0058] The rotation of the lead screw 33 is controlled by a motor. Since the lifting column 32 is threadedly connected to the lead screw 33 and the first positioning column 35 restricts the rotation of the lifting ring 3, the lifting column 32 drives the lifting ring 3 to slide up and down. When the lifting ring 3 drives the bidirectional lead screw 34 to move up and down, the gear 31 on the bidirectional lead screw 34 meshes with the rack 12 for transmission, so that the bidirectional lead screw 34 rotates during the movement of the lifting ring 3.

[0059] The two ends of the bidirectional screw rod 34 are respectively sleeved with first positioning columns 35, the inner wall of the first positioning column 35 is threadedly connected to the bidirectional screw rod 34, the first positioning column 35 is horizontally slidably connected to the axial groove of the inner mounting frame 4, a spline groove 36 is provided on the outer wall of the first positioning column 35, and a plurality of splines 41 are provided on the inner wall of the axial groove of the inner mounting frame 4, the splines 41 are inserted into the spline groove 36 to prevent the first positioning column 35 from rotating, and a first lifting seat 42 is fixedly connected to the lower part of the inner mounting frame 4, a fixing rod 43 is provided above the first lifting seat 42, the lower end of the fixing rod 43 is fixedly installed on the upper surface of the moving vehicle 1, the lower part of the first lifting seat 42 is sleeved on the fixing rod 43, and the first lifting seat 42 is slidably connected to the fixing rod 43.

[0060] During the rotation of the bidirectional screw rod 34, since the bidirectional screw rod 34 is threadedly connected to the first positioning column 35, and the spline 41 in the inner mounting frame 4 restricts the rotation of the first positioning column 35, the first positioning column 35 moves horizontally in the inner mounting frame 4, especially in the process of the bidirectional screw rod 34 moving upward, the first positioning column 35 is controlled to slide to the other side of the inner mounting frame 4 to ensure that the first positioning column 35 is inserted into the middle through hole of the winding drum 9, and through the sliding structure of the first lifting seat 42 and the fixing rod 43, the inner mounting frame 4 can slide synchronously with the bidirectional screw rod 34.

[0061] The inner mounting frame 4 and the outer mounting frame 5 are symmetrical with respect to the protective assembly 2. The inner mounting frame 4 and the outer mounting frame 5 of the same group can be connected by a bracket. A second lifting seat 52 is fixedly connected to the outer side of the outer mounting frame 5. The second lifting seat 52 is sleeved on a fixed seat 53. The fixed seat 53 is fixed on both sides of the mobile vehicle 1. The second lifting seat 52 is vertically slidably connected to the fixed seat 53. A second spring 54 is arranged above the fixed seat 53. The upper end of the second spring 54 is fixedly connected to the inner wall of the second lifting seat 52, and the lower end of the second spring 54 is fixedly connected to the top of the fixed seat 53.

[0062] In the initial state, the distance between the first positioning column 35 and the second positioning column 51 is greater than the length of the winding drum 9, so that the winding drum 9 can be moved between the two. After the inner mounting frame 4 rises, the distance between the first positioning column 35 and the second positioning column 51 is smaller than the winding drum 9, so that the winding drum 9 can be moved up and down.

[0063] When the second positioning column 51 and the first positioning column 35 are not positioned and installed with the winding drum 9, under the elastic force of the second spring 54, the second lifting seat 52 always tends to slide toward the fixed seat 53, so that the outer mounting frame 5 maintains the lowest point without the action of external force, which makes it convenient to push the winding drum 9 onto the friction plate 22 and then install it.

[0064] A guiding mechanism 7 is fixedly connected to the upper side of the moving vehicle 1 away from the protective component 2, a limiting frame 6 is arranged between the protective component 2 and the guiding mechanism 7, the limiting frame 6 is installed on the moving vehicle 1, the cable on the winding drum 9 passes horizontally through the through hole above the limiting frame 6, a rotating roller 71 is rotatably installed on the upper inner side of the guiding mechanism 7, a rubber pad 72 is attached to the side wall of the rotating roller 71, a plurality of protrusions are arranged on the surface of the rubber pad 72, and the protrusions on the surface of the rubber pad 72 increase the friction between the rubber pad 72 and the cable.

[0065] After the cables of the two winding drums 9 are respectively passed through the through holes above the limit frames 6 on both sides, they are inserted into the guiding mechanism 7 to avoid the two strands of cable being twisted during the laying of the cable. The rubber pad 72 structure on the surface of the rotating roller 71 can avoid the cable being pinched during the cable guiding process and prevent leakage. The convex block structure on the surface of the rubber pad 72 increases the friction between the cable and the rubber pad 72, so that the rotating roller 71 can effectively push the cable to move and lay when it rotates.

[0066] The axial center portion on one side of the rotating roller 71 is rotatably connected to the inner wall of the guide mechanism 7 through an axis, and the axial center portion on the other side of the rotating roller 71 passes through the guide mechanism 7 through the axis, and the outer end of the axis passing through the guide mechanism 7 is fixedly connected to the axis of the first transmission wheel 77, and a second transmission wheel 78 is provided below one side of the first transmission wheel 77, and the second transmission wheel 78 is connected to the motor through an axis, and the first transmission wheel 77 and the second transmission wheel 78 are both sleeved with a belt 79, and the first transmission wheel 77 is connected to the second transmission wheel 78 through the belt 79.

[0067] The second transmission wheel 78 is controlled to rotate by the motor, and under the transmission action of the belt 79, the first transmission wheel 77 is controlled to rotate, and the rotating roller 71 is rotated.

[0068] Slide grooves are provided on both sides of the guide mechanism 7, and a limiting rod 76 is vertically fixedly connected to the middle of the slide groove. A lifting block 74 is sleeved on the limiting rod 76, and the lifting block 74 is vertically slidably connected to the limiting rod 76. A lifting roller 73 is installed on the inner side of the lifting block 74. The part of the limiting rod 76 located below the lifting block 74 is sleeved with a third spring 75, and the two ends of the third spring 75 are respectively fixedly connected to the lifting block 74 and the bottom inner wall of the guide mechanism 7.

[0069] Under the elastic force of the third spring 75, the lifting block 74 slides vertically upward along the limit rod 76, and the lifting roller 73 slides upward to the highest point, and clamps the cable together with the rotating roller 71. When the rotating roller 71 rotates, the friction force causes the rotating roller 71 to rotate in the opposite direction inside the lifting block 74 to pull the cable.

[0070] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
