Under the action of the shock absorber 157, the bottom of the U-shape of the rear upper swing arm 155 also abuts against the pin rod part of the swing arm ball pin 156 on the uppermost arm part of the rear steering knuckle 152.
[0053] That is, the two rear wheels 14 on both sides have independent suspensions respectively, and there is no rigid connection between the two.
[0054] The front wheel connection assembly 13 includes a front axle, a front steering knuckle, a front lower swing arm, a front swing arm tie rod, a front upper swing arm, two swing arm ball pins and a shock absorber. Its structure is basically the same as that of the rear wheel connection assembly 15, so it will not be repeated.
[0055] In this embodiment, the diameters of the front and rear wheels and the arrangement of the front and rear wheel connecting assemblies ensure that the bottom ground clearance of the middle carrier frame 113 is at least 300 mm.

[0064] like Figure 7 As shown, the frame 31 includes a cable drum mounting portion 311 and a guide wheel mounting portion 312 .
[0065] The cable drum loading part 311 is used to load the cable drum. The cable drum loading part 311 includes two mounting plates 3111 in the shape of long strips, four longitudinal support columns 3112, three transverse connecting columns 3113 and two inclined oblique supporting columns 3114. The overall structure is vertically connected, surrounded by three sides, and the other side is open. There are also two cylinders 3115 at the position where the two oblique supporting columns 3114 are connected to the longitudinal supporting column 3112. The inner side of the cylinder 3115 is a through clamp mounting hole 3115a. The axial directions of the pair of clamp mounting holes 3115a are consistent and aligned in the axial direction. One of the cylinders 3115 also has a mounting column 116 on its upper surface, and the extension direction of the mounting column 116 is the same as that of the support column 3112.
[0066] The guide wheel mounting portion 312 is used to mount the guide wheel, and includes two guide wheel mounting rods 3121 that are L-shaped as a whole and square in cross section. The lower portion of the guide wheel mounting rod 3121 is fixed on a support column 3112.

In an alternative solution, the frame 31 can also be detachably mounted on the frame 11 by other assembly methods in the prior art, or welded and fixed on the frame 11. In the case where the frame 31 is detachable, different adapted frames 31 can be replaced and used according to parameters such as the size and weight of the cable drum to be used.
[0068] Figure 8 yes Figure 1 An enlarged view of the portion within frame A.
[0069] like Figure 8 As shown, the wire drum clamp 32 includes a first abutment member 321 and a second abutment member 322 .
[0070] The first abutment member 321 has a coaxial first abutment head 3211 and a first mounting column (not shown in the figure). The first abutment head 3211 is in the shape of a truncated cone, and its maximum diameter is larger than the inner diameter of the fixture mounting hole 3115a. The first mounting column is in the shape of a cylinder and its diameter is smaller than the inner diameter of the fixture mounting hole 3115a. The length of the first mounting column is larger than the length of the fixture mounting hole 3115a. The first abutment member 321 is rotatably mounted at one of the fixture mounting holes 3115a through a pair of bearings.
[0071] The second abutment member 322 has a coaxial second abutment head 3221 and a second mounting column 3222. The second abutment head 3221 is also in the shape of a truncated cone and has substantially the same size as the first abutment head 3211. The second mounting column 3222 is in the shape of a cylinder, and its diameter is slightly smaller than the inner diameter of the clamp mounting hole 3115a, and its length is much larger than the length of the clamp mounting hole 3115a. The second mounting column 3222 can be movably engaged in the clamp mounting hole 3115a on the other side. In addition, a pull rod connecting portion 32221 is formed on the outer surface of the end of the second mounting column 3222 away from the second abutment head 3221.
[0072] The smaller diameter end of the first abutment 3211 and the smaller diameter end of the second abutment 3221 face each other, and the inner diameter of the central axis hole of the cable drum is slightly smaller than the maximum diameter of the first abutment 3211 and the second abutment 3221. In addition, in this embodiment, the first abutment 3211 and the second abutment 3221 are detachable.
[0073] Fig. 9 is a three-dimensional diagram of the cable laying device in use in this embodiment, Fig.10 It is a top view of the cable laying device in use in this embodiment.
[0074] like Fig. 9 and Fig.10 As shown, the first abutment head 3211 of the first abutment member 321 and the second abutment head 3221 of the second abutment member 322 respectively abut against the two ends of the central axis hole of the cable drum 200, so that the cable drum 200 can be rotatably loaded on the reel 30 and the cable drum 200 is centering.
[0075] In addition, if Fig.10 As shown, when installed on the retractable wire rack 30, the axial direction of the cable drum 200 is consistent with the length direction of the vehicle chassis 10, the width of the vehicle chassis 10 is greater than the diameter of the cable drum 200, and the cable drum 200 is approximately located in the middle of the width direction of the vehicle chassis 10. In addition, the three sides of the cable drum 200 are surrounded by the frame 31, which can protect the cable drum 200.
[0076] The cable drum clamping mechanism 33 is used to adjust the distance between the second abutment member 322 and the first abutment member 321, thereby adjusting the degree of clamping of the cable drum by the two. The cable drum clamping mechanism 33 includes a clamping adjustment hand wheel 331, a clamping reducer 332, a clamping torque arm 333 and a clamping pull rod 334.
[0077] The clamping reducer 332 is roughly rectangular in shape and is installed on the top of the mounting column 3116. The rotating shaft of the clamping adjustment hand wheel 331 is connected to the input end of the clamping reducer 332, the wider end of the clamping torque arm 333 is connected to the output end of the clamping reducer 332 through the rotating shaft, the other end of the clamping torque arm 333 is rotatably connected to one end of the clamping pull rod 334, and the other end of the clamping pull rod 334 is rotatably connected to the pull rod connecting part 32221 on the second abutment member 322 through the rotating shaft.
[0078] When the construction worker turns the clamping adjustment hand wheel 331 by hand, the clamping reducer 332 drives the clamping torque arm 333 to rotate accordingly with a greater torque, and drives the second abutment member 322 to move through the clamping pull rod 334, thereby clamping or loosening the cable drum.
[0079] The wire drum driving mechanism 34 includes a wire drum driving driving wheel 341 , a wire drum driving driven wheel 342 , a wire drum driving timing belt 343 and a wire drum driving motor 344 .
[0080] The wire drum drive driving wheel 341 is a synchronous pulley, which is coaxially fixed on the output shaft of the wire drum drive motor 344. The wire drum drive driven wheel 342 is a synchronous pulley with a diameter larger than that of the wire drum drive driving wheel 341, which is coaxially fixed on the other end of the first mounting column of the first abutment member 321. The wire drum drive synchronous belt 343 is sleeved on the wire drum drive driving wheel 341 and the wire drum drive driven wheel 342.
[0081] Therefore, under the drive of the cable drum driving motor 344, the cable drum driving active wheel 341 and the cable drum driving driven wheel 342 rotate synchronously, driving the first abutment member 321 to rotate synchronously, thereby driving the cable drum 200 clamped by the cable drum clamp 32 to rotate. When the cable drum 200 rotates in one direction, the cable drum can be released; when it rotates in the opposite direction, the cable drum can be taken up.
[0082] The cable guide mechanism 35 is used to guide the cable released from the cable drum, or to guide the cable to be collected on the cable drum. The cable guide mechanism 35 includes a tensioning wheel 351, a first guide wheel 352 and a second guide wheel 353. In this embodiment, the three wheels are all wire storage guide wheels, and the wheel edges have a U-shaped groove with a U-shaped cross-section. Among them, the first guide wheel 352 is installed on the top of a higher guide wheel mounting rod 3121, and the second guide wheel 353 is installed on the top of the other guide wheel mounting rod 3121. The surface directions of the first guide wheel 352 and the second guide wheel 353 are both approximately perpendicular to the width direction of the vehicle chassis 10.
[0083] A vertical guide rod 3122 is also installed on one side of the guide wheel mounting rod 3121 on which the first guide wheel 352 is installed. The vertical guide rod 3122 is a round rod. One end of the tension wheel 351 bracket is sleeved on the vertical guide rod 3122, so that the tension wheel 351 can move in the vertical direction. The surface direction of the tension wheel 351 is inclined relative to the width direction of the vehicle chassis 10, and its inclination angle relative to the width direction of the vehicle chassis 10 is close to the inclination angle of the line connecting the centers of the first guide wheel 352 and the second guide wheel 353 relative to the width direction of the vehicle chassis 10.
[0084] The cable extending from the cable drum 200 is sequentially wound around the first guide wheel 352, carried on the tensioning wheel 351, carried on the second guide wheel 353, and then extended to the cable traction mechanism 40. The cable traction mechanism 40 pulls the cable, thereby cooperating with the cable drum driving mechanism 34 to reel in or unwind the cable.
[0085] Fig.11 is a three-dimensional diagram of the cable traction mechanism in this embodiment.

The main pinch wheel 441 and the auxiliary pinch wheel 442 are rotatably mounted on the traction movable frame 422, and are respectively located above the main traction wheel 432 and the main output wheel 431. The straight sections of the main transmission belt 433 and the auxiliary transmission belt 443 that face each other are roughly parallel.
[0093] The clamping adjustment assembly 45 is used to adjust the distance between the clamping wheel assembly 44 and the driving wheel assembly 43, thereby adjusting the clamping degree of the cable. The clamping adjustment assembly 45 includes a clamping adjustment handwheel 451, a screw rod 452 and a nut, wherein one end of the screw rod 452 is fixed on the traction fixed frame 421, and the other end is installed with the clamping adjustment handwheel 451, and the screw rod 452 passes through the mounting hole in the middle of the traction movable frame 422. The nut is sleeved on the screw rod 452 and abuts against the upper end of the traction movable frame 422.
[0094] Driven by the traction drive motor 434, the main output wheel 431 rotates, driving the main transmission belt 433 and the main traction wheel 432 to rotate synchronously, thereby driving the cable clamped by the main traction wheel 432 and the main pressure wheel 441 to move along its axial direction. At the same time, the cable drum drive mechanism 34 drives the cable drum to rotate, thereby realizing wire release or wire reeling.
[0095] Fig.12 It is a three-dimensional diagram of the lifting mechanism in this embodiment.
[0096] like Fig.12 As shown, the lifting mechanism 50 includes a lifting loading plate 51, a plurality of horizontal guide rails 52, a lifting balance assembly 53 and a lifting drive cylinder (not shown in the figure).
[0097] The two lower horizontal guide rails 52 are installed on a plurality of installation frames 115 , and the lifting and lowering loading plate 51 is fixed on the two upper horizontal guide rails 52 .
[0098] The lifting balance assembly 53 is used to keep the lifting loading plate 51 horizontal during the lifting process, and includes a plurality of fixed bearings 531, a plurality of movable bearings 532, a supporting bearing 533, a plurality of strip-shaped supporting plates 534 and a plurality of supporting rods 535. The supporting rods 535 are all round rods.
[0099] The fixed bearing shaft 531 is installed on the end of the same side of the four horizontal guide rails 52 , and both ends of the two support rods 535 are respectively installed on the fixed bearing shaft 531 .
[0100] The movable bearing shafts 532 are movably embedded in the inner sliding grooves of each horizontal guide rail 52 , and the two ends of the other two support rods 535 are respectively installed on the movable bearing shafts 532 .
[0101] The support plate 534 has mounting holes at both ends and in the middle, respectively. The two ends of the support plate 534 are respectively mounted on one end of the two support rods 535, and the two support plates 534 on the same side are arranged in an X shape. Support bearing shafts 533 are installed at the mounting holes in the middle of the two support plates 534 on the same side, and the two ends of another support rod 535 are respectively mounted on the two support bearing shafts 533.
[0102] When the lifting drive cylinder is started and the lifting loading plate 51 is lifted, the lifting loading plate 51 drives the two horizontal guide rails 52 above to lift, and then drives the movable bearing shaft 532 and the support rod 535 to move, pulling the support plate 534, so that the angle between the two support plates 534 on the same side changes, and the X-shaped arrangement of the two support plates 534 on the same side will keep the lifting loading plate 51 horizontal during the lifting process.
[0103] The wire drum traction mechanism 60 includes an electric winch 61 and a winch guide wheel 62 .
[0104] The electric winch 61 is installed on one side of the middle bearing frame 113. The winch guide wheel 62 is installed below a horizontal connection column 3113 of the frame body 31 and faces the electric winch 61. When in use, it is necessary to install a corresponding lifting tool at the central axis hole of the cable drum, and then the traction rope of the electric winch 61 is passed around the winch guide wheel 62 and connected to the lifting tool, and then the cable drum can be pulled by the electric winch 61.
[0105] In addition, a foldable bridge plate (not shown in the figure) is installed on the frame 11. When in the folded state, the bridge plate is stored on the frame 11; when in the unfolded state, the upper surface of the bridge plate can form an inclined surface from the ground to the lifting loading plate 51.
[0106] In addition, the cable laying device 100 of this embodiment also has a control mechanism, including multiple PLC controllers, remote control devices, and multiple motor controllers. The remote control device can receive remote control signals and transmit the information in the remote control signals to the PLC controller and the motor controller. One of the PLC controllers controls the traction drive motor 434 according to the remote control information, that is, controls the traction speed of the cable; the other PLC controller controls the cable drum drive motor 344 according to the remote control information, that is, controls the speed at which the cable drum releases the cable. The motor controller controls the front drive motor 22 and the rear drive motor 24 according to the remote control information, that is, controls the speed at which the cable laying device 100 travels.
[0107] Before laying or recycling cables, the cable drum must first be loaded onto the cable laying device 100. Specifically, the construction personnel can unfold the folding bridge plate to form an inclined surface from the ground to the lifting and loading plate 51, install the lifting tool at the central axis hole of the cable drum, and connect it to the electric winch, start the electric winch, pull the cable drum along the inclined surface to the lifting and loading plate 51, and remove the lifting tool. Then, start the lifting drive cylinder to lift the cable drum until its central axis hole is roughly aligned with the two clamp mounting holes 3115a in the axial direction, and then turn the clamping adjustment handwheel 331 to clamp the cable drum with the cable drum clamp 32. Then start the lifting drive cylinder to lower the lifting and loading plate 51 so that it is no longer in contact with the cable drum, and the cable drum can be rotated at this time. Afterwards, pull out a part of the cable on the cable drum, and pass the cable around the upper end of the first guide wheel 352, the lower end of the tensioning wheel 351 and the upper end of the second guide wheel 353 in turn, and then pass the cable through the positioning frame 41 and between the driving wheel assembly 43 and the pressure wheel assembly 44, and turn the pressure adjustment hand wheel 451 to make the driving wheel assembly 43 and the pressure wheel assembly 44 clamp the cable, and then you can start laying or recycling the cable.
[0108] Then, when laying the cable, the power mechanism 20 drives the vehicle chassis 10 to move at a certain moving speed, the cable traction mechanism 40 pulls the cable in the opposite direction of the vehicle chassis 10 at a traction speed corresponding to the moving speed of the vehicle chassis 10, and the cable drum driving mechanism 34 drives the cable drum to rotate at a rotation speed corresponding to the traction speed to gradually release the cable, thereby laying the cable.
[0109] When recovering the cable, the power mechanism 20 drives the vehicle chassis 10 to move in the opposite direction at a certain moving speed, the cable traction mechanism 40 pulls the cable in the opposite direction of the vehicle chassis 10 at a traction speed corresponding to the moving speed of the vehicle chassis 10, and the cable drum driving mechanism 34 drives the cable drum to rotate in the opposite direction at a rotation speed corresponding to the traction speed to recover the cable.
[0110] After the laying is completed or the cable is recovered, the cable drum can be unloaded in the same way. Specifically, the construction personnel can start the lifting drive cylinder to raise the lifting loading plate 51 and load the cable drum onto the lifting loading plate 51, then turn the clamping adjustment hand wheel 331 to loosen the cable drum by the cable drum clamp 32, and install the lifting tool at the central axis hole of the cable drum and connect it to the traction rope of the electric winch 61, and unfold the folding bridge board at the same time, and then with the assistance of the electric winch 61, move the cable drum from the lifting loading plate 51 along the inclined surface of the bridge board to the ground, thereby completing the unloading of the cable drum.
[0111] Example 1 Function and Effect
[0112] The cable laying device provided in this embodiment includes a vehicle chassis, a power mechanism for driving the vehicle chassis to move, and a retractable wire rack arranged on the vehicle chassis, so that the cable reel can be installed on the retractable wire rack, and the cable reel can be transported to the destination through the vehicle chassis, and the cable can be released while driving, thereby realizing the laying of the cable. In particular, the retractable wire rack includes a frame body and a reel clamp arranged on the frame body, and the reel clamp can clamp the two axial ends of the cable reel, so that the cable reel can be rotatably arranged on the frame body, and the retractable wire of the cable is realized by the rotation of the cable reel, and there is no need to use tooling of corresponding specifications, and there is no need to be equipped with special tools, so the operation is more convenient, which can further reduce the labor burden of workers and improve the efficiency of cable laying.
[0113] In the embodiment, the vehicle chassis is an off-road vehicle chassis, so the cable laying device can stably move on various terrains and can lay cables well even in complex environments such as rugged ground and muddy ground.
[0114] In the embodiment, the wire reel frame includes a frame body, a wire reel clamp and a wire reel driving mechanism, wherein the frame body is detachably mounted on the vehicle frame by bolts, so that the frame body can be conveniently replaced according to the cable reel to be used. The wire reel clamp includes two abutting members, whose ends are in the shape of a truncated cone, so that the cable reel can be conveniently clamped by abutting the two ends of the central axis hole of the cable reel, so that the cable reel can be rotatably arranged on the frame body to realize wire reeling and releasing, and at the same time, the conical surface of the abutting member can be used to center the cable reel.
[0115] Furthermore, the frame includes multiple longitudinal support rods, transverse connecting rods and two inclined diagonal support rods. The clamp mounting holes for installing the cable reel clamp are arranged at the connecting positions of the support rods, the connecting rods and the diagonal support rods. Therefore, the cable reel clamp can be well supported, and the frame surrounds the cable reel thereon on three sides, so it can also protect the cable reel during the process of reeling and releasing the wires, and can effectively avoid the impact of debris in the environment on the output or reeling of the cable reel, thereby improving the reliability of the cable laying device when operating in a complex environment.
[0116] Furthermore, the cable reel also includes a cable guiding mechanism, including two guide wheels and a tensioning wheel. By winding the cable led out from the cable drum around the two guide wheels and a tensioning wheel, the cable can be guided and limited to a certain extent, so that it can be continuously and smoothly discharged, avoiding excessive bending of the cable during the reeling process, which may affect the discharge or release of subsequent cable segments.
[0117] Furthermore, the guide wheel is arranged at a higher position relative to the vehicle chassis through the L-shaped rod in the frame, which can also avoid the impact of debris in the environment on the cable output or reeling in, thereby improving the reliability of the cable laying device when operating in a complex environment.
[0118] In an embodiment, the cable laying device further has a cable traction mechanism, which can pull the cable led out from the cable drum to extend it from one end in the length direction of the vehicle chassis, thereby cooperating with the cable drum driving mechanism to automatically lay or recycle the cable.
[0119] Furthermore, the cable traction mechanism has a positioning frame, a driving wheel assembly using a transmission belt, and a pressure wheel assembly, so that the cable led out from the cable drum can be axially positioned, and the cable segment can be effectively compressed and driven to move through the main traction wheel, the main and auxiliary pressure wheels, and the main and auxiliary transmission belts, so that not only the cable can be pulled, but also the traction speed can be accurately controlled, which is conducive to realizing automatic control, for example, the traction speed is set to be basically consistent with the moving speed of the vehicle chassis, thereby realizing automatic laying of the cable.
[0120] In the embodiment, the cable laying device also has a foldable bridge plate, a lifting mechanism and a cable drum traction mechanism, and the cable drum can be transferred to the lifting loading plate of the lifting mechanism through the unfolded bridge plate, and can be easily transferred with the assistance of the cable drum traction mechanism during the transfer process, and then the cable drum can be lifted to a corresponding height through the lifting mechanism, and then the cable drum is installed on the frame through the clamp. The cable drum is usually very heavy, and it often takes multiple people to manually carry it to a frame position higher than the ground, which is very time-consuming and labor-intensive, and there are safety risks. Through the lifting mechanism and the cable drum traction mechanism, the cable drum can be easily installed in place.
[0121] In the embodiment, the cable laying device also has multiple motor controllers, multiple PLC controllers and remote control devices, which can receive remote control signals and control the motors for driving the wheels, the motors for driving the cable drums and the motors for driving the main traction wheels accordingly. In other words, the cable laying device can be remotely controlled to move and lay cables. There is no need for construction personnel to always operate the device. The cable laying device can go to complex environments and high-risk environments to lay cables under remote control, which can greatly improve the safety of cable laying.
[0122] <Example 2>
[0123] This embodiment provides a cable laying device. In this embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.
[0124] Fig.13 It is a three-dimensional diagram of the cable laying equipment in this embodiment.
[0125] like Fig.13 As shown, the cable laying equipment 1000 includes two cable laying devices 100 of the first embodiment and a connecting device.
[0126] The two cable laying devices 100 are arranged in a width direction and close to each other, and the close edges are connected by a connecting device. As described above, there are multiple mounting frames 115 on both sides of the width direction of the frame 11, and the connecting device can use these mounting frames 115 to connect the two cable laying devices 100.
[0127] The connection device may include, for example, a supporting connection member and a buffer member, wherein the supporting connection member includes a main body portion in a strip shape with a certain width and sufficient rigidity and a plurality of catch portions extending from both sides of the main body portion, wherein the catch portions catch the mounting frame 115 on the side of the cable laying device 100. The buffer member has a certain elasticity and is coated on the catch portion, so that the catch portion can better catch the mounting frame 115 and can prevent the catch portion from being damaged by a rigid collision with the mounting frame 115 during operation.
[0128] For another example, the connecting device may include a plurality of identical snap fasteners having a certain length and sufficient rigidity, with the two ends of each snap fastener respectively grasping two mounting frames 115 at corresponding positions on the two cable laying devices 100. Similarly, an elastic layer or the like may be provided at the snap fastener's snap opening.
[0129] Since the diameter of the cable drum is smaller than the width of the vehicle chassis 10, connecting two cable laying devices 100 side by side will not affect the rotation of the cable drum, that is, it will not affect the cable drum's reeling and unreeling. At the same time, since the cable guide mechanism 35 and the cable traction mechanism 40 allow the cables on the cable drum to extend from one end in the length direction of the vehicle chassis 10, the side-by-side connection will not affect the laying of the cables at all.
[0130] Since the width of the middle load-bearing frame 113 is roughly the same as the distance between the outer ends of the two front wheels 12 (or the two rear wheels 14), in the width direction of the vehicle chassis 10, the outer ends of the two front wheels 12 (or the two rear wheels 14) are roughly flush with the mounting frames 115 on both sides of the width direction of the frame 11. Therefore, after the two side-by-side cable laying devices 100 are connected by a connecting device, the wheels of the two cable laying devices 100 can maintain an appropriate distance between each other and will not affect each other.
[0131] In addition, since the cable laying device 100 is provided with a remote control device and can receive remote control signals, multiple cable laying devices 100 in the cable laying device 1000 can be conveniently moved and cable laid at substantially the same speed through remote control.
[0132] exist Fig.12 Although only the cable laying equipment 1000 including two cable laying devices 100 is shown, it can be understood that more cable laying devices 100 can be connected side by side in the same way to form the cable laying equipment 1000.
[0133] In addition, in Fig.12 As shown, in the case where the cable laying equipment 1000 only includes two cable laying devices 100, the pay-off racks 30 on the two cable laying devices 100 can also be installed back to back on their respective frames, that is, one side openings of the two frames 31 are back to back. In this way, after the two cable laying devices 100 are connected, the cable reels loaded on each can be easily replaced.
[0134] In this embodiment, other structures are the same as those in the first embodiment, and thus will not be described again.
[0135] Example 2 Function and Effect
[0136] According to the cable laying device provided in this embodiment, based on the functions and effects of the first embodiment, since there are multiple cable laying devices connected by a connecting device, multiple cables can be laid at the same time, which can greatly improve the cable laying efficiency in scenarios where large-scale cable laying is required. In addition, in complex environments such as rugged ground, the movement of multiple cable laying devices in parallel is more stable.
[0137] In the embodiment, the cable led out from the cable drum on the reel-and-reel rack is led out from one end in the length direction of the vehicle chassis through the guiding action of the cable guiding mechanism and the traction and positioning action of the cable traction mechanism, and the two cable laying devices are arranged and connected along the width direction thereof, thereby having no influence on the laying of the cables, and the two cable laying devices connected side by side can perform the cable laying normally.
[0138] In the embodiment, there are multiple mounting frames on both sides of the frame, and the connecting device can use these mounting frames to conveniently connect two cable laying devices. In addition, in the width direction of the frame, the mounting frames on both sides are substantially flush with the outer ends of the four wheels, so after the two cable laying devices are connected by the connecting device, the normal operation of the wheels is not affected at all.
[0139] <Example 3>
[0140] This embodiment provides a cable laying device. In this embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.
[0141] Fig.14 is a three-dimensional diagram of the cable laying device in use in this embodiment, Fig.15 It is a three-dimensional diagram of the retractable wire rack in this embodiment.
[0142] like Fig.14 and Fig.15 As shown, compared with the first embodiment, the difference is that the cable laying device 100' of this embodiment does not have a cable guide mechanism 35, and the structure of the retractable wire rack 30' is also different. Compared with the first embodiment, the frame body 31 of the retractable wire rack 30' of this embodiment does not have a guide wheel mounting portion 312, and the wire drum loading portion 311' does not have an inclined support column 3114, and one side opening of the retractable wire rack 30' faces one end in the length direction of the vehicle frame 11, and the axial direction of the cable drum 200 installed on the retractable wire rack 30' is consistent with the width direction of the vehicle chassis 10. In this way, naturally, the cable released from the cable drum 200 extends roughly along the length direction of the vehicle chassis 10 toward the rear of the vehicle, and the structure of the cable guide mechanism 35 can be omitted to achieve roughly the same effect, and the cable extending from the cable drum 200 can be directly connected to the cable traction mechanism 40.
[0143] In addition, a bare rod cable arranger 70 is also provided on the frame 11 of the cable laying device 100' of the present embodiment. When the cable is recovered, the cable can be passed through the guide seat on the bare rod cable arranger 70, and the bare rod cable arranger 70 is started at the same time. The bare rod cable arranger 70 will drive the cable to move back and forth along the axial direction of the cable drum during the cable recovery process, so that the cable is wound onto the cable drum in circles in sequence. The bare rod cable arranger 70 has a release handle. In the default state, the guide seat will move along the bare rod under the drive, driving the cable to move back and forth, and when the release handle is pressed down, the guide seat can move freely along the bare rod. Therefore, the cable extending from the cable drum can be passed through the guide seat in advance, and before the cable is laid, the release handle of the bare rod cable arranger 70 is pressed to make the guide seat in a freely movable state, so that the laying of the cable will not be affected.
[0144] In this embodiment, other structures are the same as those in the first embodiment, and thus will not be described again.
[0145] In addition, the cable laying device 100' of this embodiment can also be composed of a plurality of cable laying devices 100' arranged in parallel to form a cable laying device capable of automatically laying a plurality of cables simultaneously, as in the second embodiment.
[0146] Example 3 Function and Effect
[0147] According to the cable laying device provided in this embodiment, since the axial direction of the cable drum on the retractable wire rack is consistent with the width direction of the vehicle chassis, the cable extending from the cable drum naturally extends along the length direction of the vehicle chassis. In this way, the extended cable can be directly connected to the cable traction mechanism. While the automatic cable laying function can be realized, multiple guide structures such as guide wheels can be omitted, so that the overall structure of the cable laying device is more streamlined and the overall size is smaller, which is conducive to enabling the cable laying device to lay cables in some spaces with limited dimensions. However, since the cable drum is arranged on the vehicle with the axial direction consistent with the width direction of the vehicle chassis, there is a certain limitation on the size of the cable drum, and the maximum cable drum size that can be carried is smaller than the cable laying device of the first embodiment.
[0148] Furthermore, in such a cable laying device, a bare-pole cable arranger can be conveniently arranged on the frame, and the cables extending from the cable reel can be pre-passed through the guide seat of the bare-pole cable arranger. When paying out the cables, the guide seat is set to a free-moving state without affecting the paying out of the cables. When collecting the cables, the bare-pole cable arranger can automatically arrange the cables more neatly and beautifully, thereby obtaining a cable reel with better quality.
