Description

Technical Field

[0001] This invention belongs to the technical field of intelligent cable laying vehicles, specifically an intelligent cable laying vehicle. Background Technology

[0002] Cables are used to transmit and distribute electrical energy. Intelligent cable laying vehicles are intelligent vehicles that control the cable reel to transport cables to the required location. The cable laying vehicle is then connected by a motor to automatically lay cables. It mainly consists of a cable reel and a motor and is widely used in the construction industry.

[0003] The existing intelligent cable laying vehicle first requires staff to load the cable reel with cable into the truck and then use pads to hold the bottom of the cable reel in place to prevent it from falling off due to inertia during the truck's journey. Once it reaches the designated location, a crane places the cable reel onto the intelligent vehicle for clamping, and then staff start the motor to rotate the reel and lay the cable.

[0004] Existing intelligent cable laying vehicles, after the cable reel with cable is loaded onto the vehicle, are so large that workers can only place pads at the bottom to prevent it from slipping. However, when driving over speed bumps and on bumpy roads, the high speed can cause the cable reel to have too much inertia and the pads to fail to hold it in place, and it will still fall off. In addition, the cable reel will be bumped up and down during the bumpy process, causing damage to the bottom. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the vehicle includes a chassis 1 and a vehicle body 21. The chassis 1 is fixedly connected to the front of the vehicle body 21. A motor 7 is slidably connected to one side of the inner bottom of the chassis 1 via a side frame. A cable reel 2 is provided inside the chassis 1. Buffer components 12 corresponding to the bottom sides of the cable reel 2 are fixedly connected to the inner bottom of the chassis 1. A first lead screw 8 and a second lead screw 9 are slidably connected between the inner walls of the bottom sides of the chassis 1. Two limiting rods 22 are fixedly connected between the bottom sides of the chassis 1. A first clamping plate 6 and a second clamping plate 10, which are slidably connected to the two limiting rods 22, are respectively connected to the surfaces of the first lead screw 8 and the second lead screw 9. The first clamping plate 6 and the second clamping plate 10 are arranged opposite to each other and are located on both sides of the cable reel 2. A transmission component for transmitting the first lead screw 8 and the second lead screw 9 to move in opposite directions is fixedly connected to the output end of the motor 7.

[0033] like Figure 9 and Figure 10As shown, the transmission component includes an output shaft 15. The transmission end of the motor 7 is fixedly connected to the output shaft 15. A second gear 17 is fixedly connected to the outer side of the output shaft 15. The top and bottom of the second gear 17 are movably meshed with rack plates 18. One side of each rack plate 18 is movably meshed with a first gear 16. The inner walls of the two first gears 16 are respectively fixedly connected with a first threaded sleeve 25 and a second threaded sleeve 26 that are adapted to the first lead screw 8 and the second lead screw 9. The inner walls of the two first gears 16 are threadedly connected to the first lead screw 8 and the second lead screw 9 through the first threaded sleeve 25 and the second threaded sleeve 26.

[0034] The internal threads of the first threaded sleeve 25 and the second threaded sleeve 26 are opposite, and the first threaded sleeve 25 and the second threaded sleeve 26 drive the corresponding first lead screw 8 and the second lead screw 9 to move in opposite directions, thereby driving the first clamping plate 6 and the second clamping plate 10 to clamp the cable reel 2.

[0035] Specifically, a first movable sleeve 24 and a second movable sleeve 27 are fixedly connected to the surfaces of the first lead screw 8 and the second lead screw 9, respectively. A first clamping plate 6 and a second clamping plate 10 are connected to the first movable sleeve 24 and the second movable sleeve 27, respectively. The two ends of the first lead screw 8 and the second lead screw 9 pass through both sides of the chassis 1, respectively. A first threaded rotating sleeve 25 and a second threaded rotating sleeve 26 are threaded onto one side of the first lead screw 8 and the second lead screw 9, respectively, and pass through the first threaded rotating sleeve 25, the second threaded rotating sleeve 26 and the chassis 1, respectively. The rotating shafts on one side of the first threaded rotating sleeve 25 and the second threaded rotating sleeve 26 are connected to the chassis 1.

[0036] In use, the motor 7 is activated, and the output shaft 15 engages the two rack plates 18, causing the rack plates 18 to move to opposite sides. This simultaneously drives the two first gears 16, the first threaded sleeves 25 and 26 to rotate, which in turn drives the first lead screw 8 and the second lead screw 9 to rotate in opposite directions for conveying. During the conveying process, the first moving sleeve 24 and the second moving sleeve 27 on the surface will cause the first clamping plate 6 and the second clamping plate 10 to move in opposite directions. When the first clamping plate 6 and the second clamping plate 10 are conveyed by the first lead screw 8 and the second lead screw 9, the limiting rod 22 will move horizontally along its track to prevent the first clamping plate 6 and the second clamping plate 10 from moving horizontally. The second clamping plate 10 rotates with the moving sleeve 24, which in turn causes the first lead screw 8 to move forward, causing the first clamping plate 6 to press against one side of the cable reel 2 and the second lead screw 9 to pull backward, causing the first clamping plate 6 to press against the other side of the cable reel 2. This forms an opposition to the movement direction of the first lead screw 8, effectively clamping the cable reel 2 as a whole and preventing the cable reel 2 from rolling due to its large inertia during transportation by car. When the cable reel 2 is placed in the inner clamp of the buffer assembly 12, there will be a buffer pad 121 at the bottom. When there is a bumpy road section, the bottom of the cable reel 2 will vibrate, and the buffer pad 121 itself will elastically contract to buffer the vibration, reducing the damage to the bottom of the cable reel 2 caused by vibration.

[0037] Example 2

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, electric telescopic rods 11 are fixedly connected to both sides of the top of the chassis 1. A cable reel 2 is rotatably provided between the top opposite surfaces of the two electric telescopic rods 11. A support rod 14 located below the transmission component is fixedly connected to one side wall of the chassis 1. The rotating end of the cable reel 2 is connected to the support rod 14 by a first internal toothed pulley 13.

[0039] Multiple locking pins 701 are fixedly connected to the side of the motor 7 near the chassis 1, and a locking groove is provided on the side of the chassis 1 corresponding to the locking pins 701.

[0040] A third gear 23 is fixedly connected to the end of the output shaft 15. The width of the third gear 23 is greater than the width of the support rod 14. When the electric telescopic rod 11 does not lift the cable reel 2, the first internal gear pulley 13 is in a slack state. The inner width of the first internal gear pulley 13 in the slack state is greater than the width of the third gear 23.

[0041] When the electric telescopic rod 11 is not lifted, it means that the electric telescopic rod 11 is in the initial state of not being extended or retracted, that is, the cable reel 2 is supported on the buffer pad 121. At this time, the two ends of the first internal toothed pulley 13 are not stretched by the support rod 14 and the cable reel 2, that is, they are in a relaxed state.

[0042] In use, when the cable reel 2 needs to be unloaded, the motor 7 drives the output shaft 15 to rotate counterclockwise, causing the second gear 17 to move and engage the rack plate 18 to move to both sides, causing the first clamping plate 6 and the second clamping plate 10 to move to both sides of the cable reel 2 to loosen the clamping. Then, the operator pushes the motor 7 forward so that the locking pin 701 is engaged in the corresponding slot in the chassis 1, and then the third gear 23 at the top of the output shaft 15 is engaged with the inner wall of the first internal gear pulley 13. Then, the electric telescopic rod 11 drives the cable reel 2 to rise, while tightening the first internal gear pulley 13 and engaging it with the outer surface of the third gear 23 at the top of the output shaft 15. Then, the motor 7 drives the output shaft 15 to rotate, causing the first internal gear pulley 13 to rotate and the cable reel 2 to unload the cable.

[0043] like Figure 7 and Figure 8 As shown, a rubber pad 19 is fixedly connected to one side of the first clamping plate 6, and a round bead 20 is fixedly connected to the surface of the rubber pad 19. The round bead 20 is made of rubber. The materials and structures of the first clamping plate 6 and the second clamping plate 10 are consistent. The materials of the first clamping plate 6 and the second clamping plate 10 can be plastic or alloy. A buffer pad 121 is fixedly connected inside the buffer assembly 12.

[0044] Example 3

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, side baffles 3 are fixedly connected to both sides of the chassis 1, and a first top cover 4 is fixedly connected to the top of the side baffles 3. Sliding grooves 401 are provided on both sides of the top of the first top cover 4. A second top cover 5 is slidably connected to one side of the first top cover 4. Sliding balls 501 are fixedly connected to both sides of the bottom of the second top cover 5. The second top cover 5 is slidably connected to the inner wall of the first top cover 4 by the sliding balls 501.

[0046] During use, if it rains while the chassis 1 is moving along the wheels driven by the vehicle body 21, the staff can pull the top handle of the second top cover 5 to move the sliding balls 501 on both sides of the bottom of the second top cover 5, and slide them along the inner wall of the sliding groove 401 to cover the other side of the chassis 1, so that the internal cables of the chassis 1 are not damaged by rainwater.

[0047] Working principle and usage process of this invention:

[0048] In use, the motor 7 is activated, and the output shaft 15 engages with the two rack plates 18, causing the rack plates 18 to move to opposite sides. This simultaneously drives the two first gears 16, the first threaded sleeves 25 and 26 to rotate, which in turn drives the first lead screw 8 and the second lead screw 9 to rotate in opposite directions for conveying. During the conveying process, the first moving sleeve 24 and the second moving sleeve 27 on the surface will cause the first clamping plate 6 and the second clamping plate 10 to move in opposite directions. When the first clamping plate 6 and the second clamping plate 10 are conveyed by the first lead screw 8 and the second lead screw 9, the guide rod 22 will move horizontally to prevent the first clamping plate 6 and the second clamping plate 10 from moving horizontally. As the first movable sleeve 24 and the second movable sleeve 27 rotate, the first lead screw 8 moves forward, causing the first clamping plate 6 on the surface to press against one side of the cable reel 2, and the second lead screw 9 pulls backward, causing the first clamping plate 6 on the surface to press against the other side of the cable reel 2. This forms an opposition to the movement direction of the first lead screw 8, effectively clamping the cable reel 2 as a whole. This effectively prevents the cable reel 2 from rolling due to its large inertia during transportation by car. When the cable reel 2 is placed in the inner clamp of the buffer assembly 12, there will be a buffer pad 121 at the bottom. When there is a bumpy road section, the bottom of the cable reel 2 will vibrate, and the buffer pad 121 itself will elastically contract to buffer the vibration, reducing the damage to the bottom of the cable reel 2 caused by vibration.

[0049] When cable reel 2 needs to be unloaded, the output shaft 15 of motor 7 rotates counterclockwise, causing the second gear 17 to move and mesh with the rack plate 18 to move to both sides, causing the first clamping plate 6 and the second clamping plate 10 to separate from the two sides of cable reel 2 and loosen them. Then, the operator pushes motor 7 forward so that the locking pin 701 is engaged in the corresponding slot of the base plate 1, and then the top 23 of output shaft 15 is engaged with the inner wall of the first internal gear pulley 13. Then, the electric telescopic rod 11 drives cable reel 2 to rise, and at the same time tightens the first internal gear pulley 13 and engages it with the outer surface of the third gear 23 on the top of output shaft 15. Then, the motor 7 starts and drives output shaft 15, causing output shaft 15 to drive the first internal gear pulley 13 to rotate, and at the same time drive cable reel 2 to rotate to unload the cable.

[0050] After the cable reel 2 is transported to its destination, the motor 7 is restarted to drive the output shaft 15 counterclockwise, which loosens the first clamping plate 6 on the cable reel 2. Then, the motor 7 is pushed forward so that the groove of the output shaft 15 is located in the first internal gear pulley 13. Then, the electric telescopic rod 11 lifts the cable reel 2, which tightens the two sides of the first internal gear pulley 13 and clamps them into the groove of the output shaft 15. Then, the motor 7 is restarted to rotate and drive the first internal gear pulley 13 to drive the cable reel 2 to rotate and release the cable.
