The carrier is a transfer and support device of the cable laying machine, which facilitates the transportation of the cable laying machine and coordinates the lifting device to realize two working modes of laying in the cable well and above the well. The lifting device can adjust the height of the pusher, and the pusher is lowered into the cable well by the elevator and aligned with the laying pipe to realize cable laying in the cable well, or the pusher is lifted onto the carrier to realize ground cable laying. The pusher clamps the cable with a certain pre-tightening force for different cable models, and pushes and lays the cable through the friction between the cable and the rubber track of the pusher. The monitoring device realizes real-time monitoring, display and optimization control of the cable laying working parameters, and transmits the operating parameters of each cable pusher to the coordination control terminal to realize coordinated control of multiple cable conveyors on site.

The carrier is a transfer and support device for the cable laying machine, which facilitates the transportation of the cable laying machine and coordinates the lifting device to realize two working modes of laying in the cable well and above the well. The lifting device can adjust the height of the pusher, and the pusher is lowered into the cable well by the lift and aligned with the laying pipe to realize the cable laying in the cable well, or the pusher is lifted onto the carrier to realize the ground cable laying.

The monitoring device realizes real-time monitoring, display and optimization control of the cable laying working condition parameters, and transmits the operating parameters of each cable pusher to the coordination control terminal to realize the coordinated control of multiple cable conveyors on site.

[0005] However, the existing cable laying machines cannot adaptively adjust according to the radius of the cables when transporting the cables, thereby reducing the efficiency of transporting different cables. At the same time, the existing cable laying machines have insufficient transmission stability and power utilization efficiency when transporting the cables. Therefore, a power cable laying method urgently needs to be improved. Summary of the invention

[0006] The invention provides a power cable laying method to improve the adaptability of cables with different diameters and widths during the construction process, improve the transmission efficiency of different cables, and increase the stability and utilization efficiency of cable transmission.

[0007] The present invention also provides a multi-machine linkage cable laying machine for power transmission to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-machine linkage cable laying machine for power transmission, characterized in that it includes a guide device, a supporting bracket, a guide slide groove, a positioning gear, a first connecting gear plate, a fixed motor, a limit bracket, a guide gear, a second connecting gear plate and a fixed transmission shaft.

The connecting device is connected to the supporting device in a threaded manner through a connecting screw. Seven groups of limit devices are equidistantly arranged between the connecting device and the supporting device in a rotationally clamped manner, and the seven groups of limit devices are meshed and connected by guide belts.

[0013] Furthermore, the supporting device includes threaded holes, fixing holes, limit holes and a mounting plate; seven groups of limit holes are equidistantly provided on the upper end surface of the mounting plate near the front, and two fixing holes are symmetrically provided on the front of the upper end surface of the mounting plate, and two threaded holes are symmetrically provided on the rear of the upper end surface of the mounting plate.

[0014] Furthermore, the guiding device includes a limiting guide rod, a connecting sleeve, a first limiting rotating plate, a clamping pulley and a second limiting rotating plate. The center of the lower end surface of the limiting guide rod is fixedly connected with the clamping pulley, and the first limiting rotating plate is fixedly connected near the clamping pulley on the lower end surface of the limiting guide rod, the outer end surface of the limiting guide rod is slidably clamped with a connecting sleeve near the middle, and the second limiting rotating plate is fixedly connected at the center of the lower end surface of the connecting sleeve.

[0015] Furthermore, the connecting device includes a guide slide shaft, a fixed slide seat, a card-connecting socket, a fixed slider, a connecting slot and a motor slot, two guide slide shafts are symmetrically fixedly connected to the front of the upper end surface of the fixed slide seat, and seven groups of card-connecting sockets are equidistantly provided on the upper end surface of the fixed slide seat near the guide slide shafts, three groups of fixed sliders are equidistantly fixedly connected to the lower end surface of the fixed slide seat, a connecting slot is provided on the front end surface of the fixed slide seat near the end head, and a motor slot is provided on the rear end surface of the fixed slide seat near the side end head.

[0016] Furthermore, the cross sections of the fixed slider and the guide slot are both T-shaped, and the guide device is adapted to the guide slot through the fixed slider and is then slidably engaged with the inner end surface of the supporting bracket.

[0017] Furthermore, the connecting screw is adapted to the threaded hole, and the fixing hole is adapted to the guide slide shaft, and the supporting device is connected to the connecting device in a threaded sliding connection manner by adapting the connecting screw to the threaded hole and the fixing hole to the guide slide shaft.

[0018] Furthermore, the connecting sleeve is rotatably engaged with the limiting engaging hole, and the bottoms of the seven groups of limiting devices are meshedly connected with the guide belt via engaging pulleys.

[0019] Furthermore, the bottom of the outermost clamping pulley on the end of the second group of guide devices is fixedly connected to the second connecting toothed disk, and the bottom of the outermost clamping pulley on the end of the first group of guide devices is fixedly connected to the first connecting toothed disk, and a guide rotating groove is also provided in the connecting clamping groove, and the radius of the guide rotating groove is greater than the radius of the fixed transmission shaft.

[0020] Furthermore, a card-connecting motor is fixedly connected to the end face on one side of the supporting bracket, and a connecting screw is fixedly connected to the side end face of the card-connecting motor. The card-connecting motor is threadedly connected to a group of guide devices on the corresponding side of the card-connecting motor through the connecting screw.

[0021] In the power cable construction and laying method of the present invention, before laying and conveying the cable, the user positions the cable between two sets of guide devices, so as to facilitate the positioning and conveying of the cable;

[0022] During laying and conveying, the user starts the fixed motor through an external control device. At this time, the fixed motor drives the positioning gear on the side to rotate, and at the same time, the fixed motor drives the guide gear to rotate through the fixed transmission shaft. When the positioning gear and the guide gear rotate, the positioning gear drives the first connecting gear plate set at the bottom to engage and connect, and at the same time, the guide gear drives the second connecting gear plate set at the top to rotate. Since the rotation speed of the guide gear and the positioning gear is the same, the rotation speed of the first connecting gear plate and the second connecting gear plate is the same and the direction is opposite. At this time, the first connecting gear plate and the second connecting gear plate can both drive the top clamping pulley to rotate. When the clamping pulley rotates, the clamping pulley can drive the limiting guide rod to rotate, and the limiting guide rod can simultaneously drive the second limiting rotating plate and the first limiting rotating plate to rotate. The two sets of relative second limiting rotating plates and the first limiting rotating plates cooperate to play a good guiding role in the transportation of cables.

[0023] In order to adapt to cables of different radii, the user starts the clamping motor through an external control device. Since a threaded groove is provided in the fixed slide seat of the guide device, the clamping motor is threadedly connected to the threaded groove through a connecting screw rod. The rotation of the connecting screw rod drives the guide device to undergo linear displacement, thereby adjusting the lateral spacing between the two sets of guide devices.

[0024] During adjustment, the limit clamp and the guide gear can be displaced together with one set of guide devices, so that the positional relationship between the limit clamp, the guide gear and the second connecting gear plate remains unchanged, thereby facilitating subsequent transmission.

[0025] After the lateral distance between the two sets of guide devices is adjusted, the user starts the servo motor through the external control device, and the servo motor drives the toothed belt pulley to rotate, so that the toothed belt pulley drives the other set of toothed belt pulleys to rotate synchronously through the toothed belt, and the two sets of toothed belt pulleys convert the rotation action of the connecting screw into a linear displacement action of the supporting device through a threaded mechanism that cooperates with the threaded hole, thereby driving the supporting device to move upward, and at the same time, due to the sliding engagement of the connecting sleeve and the limit guide rod, the longitudinal spacing between the first limit rotating plate and the second limit rotating plate becomes larger, which is convenient for the subsequent transportation of cables with different radii.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention provides a guide device, which can be equipped with a group of fixed and a group of sliding guide devices, so that the device can adapt to the rapid transportation of cables with different radii, thereby improving the overall adaptability of the device. At the same time, the provision of multiple groups of first limit rotating plates and second limit rotating plates can effectively improve the stability of the subsequent cable transportation.

[0028] 2. The present invention provides a limit device and a guide belt, and multiple groups of limit devices can rotate synchronously under the drive of the guide belt, thereby improving the stability of the transmission and also improving the efficiency of the device in utilizing power.

[0029] 3. By using the power cable laying method of the present invention, the two sets of opposite second limit rotating plates cooperate with the first limit rotating plates to provide a good guide for the transportation of the cables.

[0030] 4. By utilizing the power cable laying method of the present invention, the guide device is driven to undergo linear displacement by the rotation of the connecting screw, thereby adjusting the lateral spacing between the two sets of guide devices.

[0031] 5. By utilizing the power cable laying method of the present invention, the connecting sleeve and the limiting guide rod are slidably engaged so that the longitudinal distance between the first limiting rotating plate and the second limiting rotating plate becomes larger, thereby facilitating the subsequent transportation of cables with different radii.

[0046] The present invention is further described below in conjunction with the accompanying drawings.

[0047] Example 1

[0048] See also Figure 1 , 3 , 4, 6 and Fig. 9 As shown, an embodiment of the present invention provides:

[0049] A power cable laying method uses a multi-machine linkage cable laying machine for power transmission.

[0050] A multi-machine linkage cable laying machine for power transmission includes a guide device 1, a support bracket 2, a guide slide 3, a positioning gear 4, a first connecting gear plate 5, a fixed motor 6, a limit bracket 7, a guide gear 8, a second connecting gear plate 9 and a fixed transmission shaft 10.

[0051] The upper end surface of the support bracket 2 is provided with three groups of guide slots 3 at equal intervals, and the upper end surface of the support bracket 2 is provided with two groups of guide devices 1 (which can be defined as a first group of guide devices 1 and a second group of guide devices 1). The upper end surface of the support bracket 2 is fixedly connected with the first group of guide devices 1, and the upper end surface of the support bracket 2 is slidably connected with the second group of guide devices 1. A fixed motor 6 is provided at a position of the upper end surface of the support bracket 2 between the two groups of guide devices 1. A first connecting toothed disc 5 is provided at a position of the upper end surface of the support bracket 2 corresponding to the end position of the first group of guide devices 1, and the upper end surface of the support bracket 2 corresponds to the second group of guide devices 1. A second connecting toothed disc 9 is provided at the end position of the second group of guide devices 1. The fixed motor 6 is a dual-output motor with two output ends along the axial direction. One output end of the fixed motor 6 is meshedly connected with the first connecting toothed disc 5 through a positioning gear 4, and the other output end of the fixed motor 6 is fixedly connected with a fixed transmission shaft 10. The interior of the second group of guide devices 1 corresponding to the second connecting toothed disc 9 is fixedly connected with a limiting clamping seat 7, and the internal rotation of the limiting clamping seat 7 is clamped with a guide gear 8, which is slidably clamped on the fixed transmission shaft 10, and the guide gear 8 is meshedly connected with the second connecting toothed disc 9.

[0052] like Figure 4 and Figure 5 As shown, the guide device 1 includes a supporting device 11, a limiting device 12, a connecting device 13, a toothed belt 14, a servo motor 15, a toothed belt pulley 16, a connecting screw 17 and a guide belt 18. The upper end surface of the connecting device 13 is symmetrically rotated and clamped with two toothed belt pulleys 16 for transmission near the rear, and a connecting screw 17 is fixedly connected at the center of the upper end surface of the toothed belt pulley 16. The two groups of toothed belt pulleys 16 are meshed and connected through the toothed belt 14. The lower end surface of the connecting device 13 is fixedly connected with the servo motor 15 at a position corresponding to one of the toothed belt pulleys 16. The upper end surface of the connecting device 13 is threadedly connected to the supporting device 11 through the connecting screw 17. Seven groups of limiting devices 12 are equidistantly rotated and clamped between the connecting device 13 and the supporting device 11, and the seven groups of limiting devices 12 are meshed and connected through the guide belt 18.

[0053] like Figure 6 As shown, the support device 11 includes a threaded hole 111, a fixing hole 112, a limit hole 113 and a mounting plate 114. The upper end surface of the mounting plate 114 is equidistantly provided with seven groups of limit holes 113 near the front, and two fixing holes 112 are symmetrically provided at the front of the upper end surface of the mounting plate 114. Two threaded holes 111 are symmetrically provided at the rear of the upper end surface of the mounting plate 114. The support device 11 can facilitate the subsequent lifting of the second limit rotating plate 125, so as to facilitate the adaptive adjustment and positioning of cables with different radii.

[0054] like Figure 7 As shown, the guide device 1 includes a limiting guide rod 121, a connecting sleeve 122, a first limiting rotating plate 123, a clamping pulley 124 and a second limiting rotating plate 125. The clamping pulley 124 is fixedly connected to the center of the lower end surface of the limiting guide rod 121, and the first limiting rotating plate 123 is fixedly connected to the lower end surface of the limiting guide rod 121 near the clamping pulley 124. The outer end surface of the limiting guide rod 121 is slidably clamped with the connecting sleeve 122 near the middle, and the second limiting rotating plate 125 is fixedly connected to the center of the lower end surface of the connecting sleeve 122, so that the second limiting rotating plate 125 is also slidably clamped to the limiting guide rod 121.

[0055] like Figure 8 and Fig. 9As shown, the connecting device 13 includes a guide slide shaft 131, a fixed slide seat 132, a card connection socket 133, a fixed slider 134, a connecting card slot 135 and a motor slot 136. Two guide slide shafts 131 are symmetrically fixedly connected to the front of the upper end face of the fixed slide seat 132, and seven groups of card connection sockets 133 are equidistantly provided on the upper end face of the fixed slide seat 132 near the guide slide shaft 131, and three groups of fixed sliders 134 are equidistantly fixedly connected to the lower end face of the fixed slide seat 132, a connecting card slot 135 is provided on the front end face of the fixed slide seat 132 near the end, and a motor slot 136 is provided on the rear end face of the fixed slide seat 132 near the end of the side. The setting of the motor slot 136 can facilitate the subsequent rapid positioning and installation of the servo motor 15.

[0056] like Figure 2 and Figure 5 As shown, the cross-sections of the fixed slider 134 and the guide slot 3 are both T-shaped, and the guide device 1 is adapted to the guide slot 3 through the fixed slider 134 and then slidably connected to the inner end surface of the supporting bracket 2. The T-shaped fixed slider 134 can ensure the stability of the connecting device 13 sliding inside the guide slot 3, thereby improving the stability of subsequent transmission.

[0057] like Figure 3-6 As shown in FIGS. 8-9 , the connecting screw 17 is matched with the threaded hole 111, and the fixing hole 112 is matched with the guide slide shaft 131. The supporting device 11 is threadedly connected to the upper part of the connecting device 13 by matching the connecting screw 17 with the threaded hole 111 and matching the fixing hole 112 with the guide slide shaft 131. The threaded connection structure of two sets of synchronously rotating connecting screws 17 and threaded holes 111 can maximize the stability and accuracy of the lifting of the supporting device 11, thereby improving the efficiency of subsequent adjustments.

[0058] like Figure 3-7 As shown, the connecting sleeve 122 is rotatably engaged with the limit clamping hole 113, and the bottoms of the seven groups of limit devices 12 are meshed and connected with the guide belt 18 through the clamping pulley 124. The connecting sleeve 122 can be rotatably engaged with the inside of the mounting clamping plate 114, so that the connecting sleeve 122 can be lifted together with the lifting of the supporting device 11, thereby facilitating the subsequent adjustment of the longitudinal distance between the first limit rotating plate 123 and the second limit rotating plate 125.

[0059] like Figure 1-3As shown in , 8, the bottom of the outermost clamping pulley 124 on the end of the second group of guide devices 1 is fixedly connected to the second connecting toothed disc 9, and the bottom of the outermost clamping pulley 124 on the end of the first group of guide devices 1 is fixedly connected to the first connecting toothed disc 5. A guide rotating groove is provided in the connecting groove 135 of the guide device 1, and the radius of the guide rotating groove is greater than the radius of the fixed transmission shaft 10. The guide rotating groove can provide sufficient limiting space for the subsequent rotation of the fixed transmission shaft 10 inside the guide device 1. A groove portion is also correspondingly provided in the guide device 1 to provide sufficient installation space for the positioning gear 4, the first connecting toothed disc 5, the limiting clamping seat 7 and the second connecting toothed disc 9.

[0060] When the present embodiment is implemented, if it is necessary to lay and transport the cables, the user can position the cables between the two sets of guide devices 1, so as to facilitate the positioning and transportation of the cables. When laying and transporting, the user can start the fixed motor 6 through the external control device. At this time, the fixed motor 6 can drive the positioning gear 4 on the side to rotate. At the same time, the fixed motor 6 can also drive the guide gear 8 to rotate through the fixed transmission shaft 10. When the positioning gear 4 and the guide gear 8 rotate, the positioning gear 4 can drive the first connecting toothed disc 5 set at the bottom to engage and connect. At the same time, the guide gear 8 can drive the second connecting toothed disc 9 set at the top to rotate, and because the guide gear 8 has the same rotation speed as the positioning gear 4, so that the first connecting toothed disc 5 and the second connecting toothed disc 9 have the same rotation speed and opposite directions. At this time, the first connecting toothed disc 5 and the second connecting toothed disc 9 can both drive the top clamping pulley 124 to rotate. When the clamping pulley 124 rotates, the clamping pulley 124 can drive the limiting guide rod 121 to rotate. The limiting guide rod 121 can simultaneously drive the second limiting rotating plate 125 and the first limiting rotating plate 123 to rotate. The two sets of relative second limiting rotating plates 125 and the first limiting rotating plates 123 can cooperate with each other, thereby playing a good guiding role in the transportation of the cables, and effectively improving the stability of the guiding transportation of the cables.

[0061] Example 2

[0062] On the basis of Example 1, Fig.10 As shown, a clamping motor 102 is fixedly connected to one side end face of the supporting bracket 2, and a connecting screw 101 is fixedly connected to the side end face of the clamping motor 102. The clamping motor 102 is threadedly connected to a group of guide devices 1 located on the corresponding side of the clamping motor 102 through the connecting screw 101.

[0063] When implementing this embodiment, if the device needs to be adjusted to adapt to cables of different radii, the user can start the clamping motor 102 through an external control device. Since a threaded groove is provided in the fixed slide 132 of the guide device 1, the clamping motor 102 can be threadedly connected to the threaded groove through the connecting screw 101, and the guide device 1 is driven to undergo linear displacement by the rotation of the connecting screw 101, thereby adjusting the lateral spacing between the two groups of guide devices 1; at the same time, when making adjustments, the limit clamp 7 and the guide gear 8 can be displaced together with one of the groups of guide devices 1, thereby keeping the positional relationship between the limit clamp 7, the guide gear 8 and the second connecting toothed disc 9 unchanged, thereby facilitating subsequent transmission.

[0064] After the lateral distance between the two groups of guide devices 1 is adjusted, the user can start the servo motor 15 through the external control device. At this time, the servo motor 15 can drive the toothed belt pulley 16 to rotate, so that the toothed belt pulley 16 can drive another group of toothed belt pulleys 16 to rotate synchronously through the toothed belt 14. The two groups of toothed belt pulleys 16 can convert the rotation action of the connecting screw 17 into a linear displacement action of the supporting device 11 through the threaded mechanism that matches the connecting screw 17 with the threaded hole 111, thereby driving the supporting device 11 to move upward. At the same time, due to the sliding engagement between the connecting sleeve 122 and the limiting guide rod 121, the longitudinal spacing between the first limiting rotating plate 123 and the second limiting rotating plate 125 becomes larger, thereby facilitating the subsequent stability and adaptability requirements for the transportation of cables with different radii.

[0065] Working principle: before laying and transporting the cables, the user can position the cables between the two sets of guide devices 1, so as to facilitate the positioning and transportation of the cables; when laying and transporting, the user can start the fixed motor 6 through the external control device, at this time, the fixed motor 6 can drive the side positioning gear 4 to rotate, and at the same time, the fixed motor 6 can also drive the guide gear 8 to rotate through the fixed transmission shaft 10. When the positioning gear 4 and the guide gear 8 rotate, the positioning gear 4 can drive the first connecting toothed disc 5 set at the bottom to engage and connect, and at the same time, the guide gear 8 can drive the second connecting toothed disc 9 set at the top to rotate, and because the guide gear 8 and the fixed gear 4 are connected The rotation speed of the positioning gear 4 is the same, so that the rotation speed of the first connecting toothed disc 5 and the second connecting toothed disc 9 is the same and the direction is opposite. At this time, the first connecting toothed disc 5 and the second connecting toothed disc 9 can both drive the top clamping pulley 124 to rotate. When the clamping pulley 124 rotates, the clamping pulley 124 can drive the limiting guide rod 121 to rotate. The limiting guide rod 121 can simultaneously drive the second limiting rotating plate 125 and the first limiting rotating plate 123 to rotate. The two sets of relative second limiting rotating plates 125 and the first limiting rotating plates 123 can cooperate with each other, thereby playing a good guiding role in the transportation of the cables, and effectively improving the stability of the cable transportation and guiding.

[0066] If the distance of the device needs to be adjusted to adapt to cables of different radii, the user can start the clamping motor 102 through an external control device. Since a threaded groove is provided in the fixed slide 132 of the guide device 1, the clamping motor 102 can be threadedly connected to the threaded groove through the connecting screw 101, and the guide device 1 is driven to undergo linear displacement by the rotation of the connecting screw 101, thereby adjusting the lateral spacing between the two groups of guide devices 1; at the same time, when adjusting, the limit clamp 7 and the guide gear 8 can be displaced together with one of the groups of guide devices 1, thereby keeping the positional relationship between the limit clamp 7, the guide gear 8 and the second connecting gear 9 unchanged, thereby facilitating subsequent transmission. After the lateral distance between the two groups of guide devices 1 is adjusted, the user can start the servo motor 15 through the external control device. At this time, the servo motor 15 can drive the toothed belt wheel 16 to rotate, so that the toothed belt wheel 16 can drive another group of toothed belt wheels 16 to rotate synchronously through the toothed belt 14. The two groups of toothed belt wheels 16 can convert the rotation action of the connecting screw 17 into a linear displacement action of the supporting device 11 through the threaded mechanism that matches the connecting screw 17 with the threaded hole 111, thereby driving the supporting device 11 to move upward. At the same time, due to the sliding engagement between the connecting sleeve 122 and the limiting guide rod 121, the longitudinal spacing between the first limiting rotating plate 123 and the second limiting rotating plate 125 becomes larger, thereby facilitating the subsequent stability and adaptability requirements for the transportation of cables with different radii.

At the same time, the fixed motor (6) drives the guide gear (8) to rotate through the fixed transmission shaft (10).

Since the rotation speed of the guide gear (8) and the positioning gear (4) is the same, the first connecting toothed disc (5) is engaged with the guide gear (8).

The two sets of opposite second limiting rotating plates (125) and the first limiting rotating plates (123) cooperate to play a good guiding role in the transportation of the cable.

2. A method for laying a power cable according to claim 1, characterized in that: In order to adapt to cables of different radii, the user starts the clamping motor (102) through an external control device. Since a threaded groove is provided in the fixed slide seat (132) of the guide device (1), the clamping motor (102) is threadedly connected to the threaded groove through the connecting screw rod (101). The connecting screw rod (101) is rotated to drive the guide device (1) to undergo linear displacement, thereby adjusting the lateral spacing between the two sets of guide devices (1). When adjusting, the limit clamping seat (7) and the guide gear (8) can be displaced together with one set of guide devices (1), so that the positional relationship between the limit clamping seat (7), the guide gear (8) and the second connecting toothed disc (9) remains unchanged, thereby facilitating subsequent transmission.
