Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and in particular to a cable laying device and method. Background Technology

[0002] In power cable engineering construction, cable laying is one of the main tasks in the construction process. After the power cables are manufactured, they are stored and transported in reels. Laying the cables off the reels is the starting point and the first step in cable laying. Cable laying is very important for the efficiency and quality of the entire power cable laying process, as well as for protecting the cables from external damage and strain.

[0003] In related technologies, the cable reel is placed directly on the rollers on both sides of the cable laying frame. The rollers can drive the cable reel to rotate and lay the cable. However, in this solution, the cable reel is prone to tipping over and slipping out, resulting in low reliability. Furthermore, the length of the cable reel must be adapted to the distance between the rollers on both sides of the cable laying frame, which greatly limits its use. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a cable laying device that can reduce the risk of cable reel tipping over or slipping out, improve reliability, and is adaptable to cable reels of different lengths, thus having a wide range of applications.

[0005] The present invention also proposes a method for using the above-mentioned cable laying equipment.

[0006] According to a first aspect of the present invention, a cable laying device includes: a laying apparatus, the laying apparatus including a base, a leveling mechanism, a support assembly, and a drive assembly; the leveling mechanism is disposed on the base and is used to level the base; the support assembly includes two support shafts rotatably disposed on the base, the two support shafts being arranged side-by-side and spaced apart in a horizontal direction, the two support shafts being used to carry a cable reel; the drive assembly being capable of driving at least one of the support shafts to rotate forward or backward; and a safety protection device, the safety protection device including a center bar, two sets of limiting components, and... Two pull bars are provided, with rotating rings connected to both ends of the central bar. Two sets of limiting components are respectively disposed at both ends of the central bar, and the two sets of limiting components are located between the two rotating rings at both ends of the central bar. The two pull bars pass through the two rotating rings at both ends of the central bar. The central bar is used to pass through the central hole of the cable reel so that the two sets of limiting components abut against both ends of the cable reel. The two ends of the pull bars are fixed to the base. The rotating rings are configured to allow the central bar to rotate relative to the pull bars when rotating with the cable reel.

[0007] The cable laying device according to embodiments of the present invention has at least the following beneficial effects:

[0008] In the cable laying device of this invention, the cable reel is placed on a support assembly. When the drive assembly drives the support assembly, it can rotate the cable reel. A safety protection device can lock the cable reel onto the support assembly. Furthermore, since the swivel ring allows the center bar to rotate relative to the pull bar as the cable reel rotates, the cable reel is limited without affecting its rotation, thereby reducing the risk of the cable reel tipping over or slipping out and ensuring construction safety. In addition, the cable reel is supported by two support shafts, which can adapt to cable reels of different lengths without adjustment. That is, for cable reels of different lengths, simply placing them on the two support shafts allows for convenient and quick cable laying and winding.

[0009] According to some embodiments of the present invention, at least one of the support shafts is movably connected to the base so that the distance between the two support shafts is adjustable.

[0010] According to some embodiments of the present invention, the base includes a guide rail extending in a direction parallel to the spacing direction of the two support shafts, wherein one of the support shafts is slidably connected to the guide rail.

[0011] According to some embodiments of the present invention, each of the support shafts is provided with two cable reel limiting members spaced apart along the axial direction of the support shaft.

[0012] According to some embodiments of the present invention, the cable reel limiting member is sleeved on the support shaft, and the cable reel limiting member is locked by screws, wherein, after the screws are removed, the cable reel limiting member is operably movable along the axial direction of the support shaft.

[0013] According to some embodiments of the present invention, the limiting assembly includes a position-adjustable limiting unit and a locking member for locking the limiting unit onto the center strip. The limiting unit includes a sleeve that is position-adjustably fitted onto the center strip and a limiting member fitted onto the sleeve and threadedly connected to the sleeve. The locking member is used to lock the sleeve onto the center strip, and the limiting member is operably movable along the axial direction of the sleeve.

[0014] According to some embodiments of the present invention, the center bar is a center chain, the sleeve is provided with an assembly hole, and the locking member is detachably inserted into the assembly hole and the hole of the center chain.

[0015] According to some embodiments of the present invention, the swivel includes a first fastener connected to the end of the center strip and a second fastener rotatably connected to the first fastener, the pull strip passing through the second fastener.

[0016] According to some embodiments of the present invention, the pull bar is a pull chain.

[0017] A method of using a cable laying device according to a second aspect embodiment of the present invention, applied to the cable laying device described above, the method of using the cable laying device includes:

[0018] The base is leveled beforehand using a leveling mechanism;

[0019] Hoist the cable reel onto the two support shafts;

[0020] Pass the center strip through the center hole of the cable reel;

[0021] Install limit switch components at both ends of the center strip;

[0022] Connect pull bars to the swivels at both ends of the center bar, and connect the pull bars to the base.

[0023] The method of using the cable laying device according to an embodiment of the present invention has at least the following beneficial effects:

[0024] In the method of using the cable laying device of the present invention, the cable reel is placed on the support assembly. When the drive assembly drives the support assembly to run, it can drive the cable reel to rotate. The safety protection device can lock the cable reel on the support assembly. Furthermore, since the swivel ring allows the center bar to rotate relative to the pull bar as the cable reel rotates, the cable reel is limited without affecting its rotation, thereby reducing the risk of the cable reel tipping over or slipping out and ensuring construction safety. In addition, by supporting the cable reel with two support shafts, it can be adapted to cable reels of different lengths without adjustment. That is, for cable reels of different lengths, simply placing them on the two support shafts can realize cable laying and winding, which is convenient and quick.

[0046] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0047] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0048] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0049] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention provides a cable laying device, including a laying device 100 and a safety protection device 400.

[0050] Combination Figure 1 and Figure 2 The display device 100 includes a base 110, a support component 120 disposed on the base 110, and a drive component 130 drivenly connected to the support component 120. The support component 120 is used to carry the cable reel 10, and the drive component 130 is used to drive the support component 120 to rotate the cable reel 10.

[0051] Specifically, the base 110 supports the support assembly 120, the support assembly 120 supports the cable reel 10, and the drive assembly 130 drives the support assembly 120 to rotate the cable reel 10. When the drive assembly 130 drives the cable reel 10 to rotate in a first rotation direction, the cable 20 can be unloaded, i.e., the cable 20 can be released from the cable reel 10. When the drive assembly 130 drives the cable reel 10 to rotate in a second rotation direction opposite to the first rotation direction, the cable 20 can be wound back onto the cable reel 10.

[0052] like Figure 3 , Figure 4 As shown, the support assembly 120 includes two support shafts 121 rotatably mounted on the base 110. The two support shafts 121 are arranged side by side and spaced apart in the horizontal direction. The drive assembly 130 can drive one of the support shafts 121 to rotate forward or backward.

[0053] Understandably, each support shaft 121 can rotate relative to the base 110 around its own axis, and the cable reel 10 can be supported on two support shafts 121. When the drive assembly 130 drives one of the support shafts 121 to rotate, it can drive the cable reel 10 to rotate; specifically, when the drive assembly 130 drives one of the support shafts 121 to rotate clockwise, it can drive the cable reel 10 to rotate in a first rotation direction; when the drive assembly 130 drives one of the support shafts 121 to rotate counterclockwise, it can drive the cable reel 10 to rotate in a second rotation direction. In addition, the two support shafts 121 are arranged side by side and spaced apart in the horizontal direction. This horizontal structure can reduce the height of the support point of the cable reel 10, which is beneficial to improving safety.

[0054] The drive assembly 130 may be a motor, which is connected to one of the support shafts 121 and is used to drive the support shaft 121 to rotate around the axis of the support shaft 121. Both ends of each support shaft 121 are connected to the base 110 through bearing seats, so that each support shaft 121 can rotate relative to the base 110 around the axis of the support shaft 121.

[0055] Of course, in other embodiments, the drive assembly 130 can also drive the two support shafts 121 to rotate forward or backward at the same time. For example, a transmission belt can be added between the two support shafts 121. When the drive assembly 130 drives one of the support shafts 121 to rotate, the other support shaft 121 can be driven to rotate through the transmission belt.

[0056] In some other embodiments, the number of drive components 130 may be two, and the two drive components 130 may synchronously drive the two support shafts 121 to rotate.

[0057] In the cable reel 100 of the present invention, the cable reel 10 is supported by two support shafts 121, which can adapt to cable reels 10 of different lengths without adjustment. That is, for cable reels 10 of different lengths, they can be placed directly on the two support shafts 121 to realize cable laying and cable winding, which is convenient and quick.

[0058] Combination Figure 4 and Figure 5 Furthermore, each support shaft 121 is also provided with two cable reel limiting members 124 spaced apart along the axial direction of the support shaft 121. The cable reel limiting members 124 are used to abut against the end of the cable reel 10, thereby restricting the cable reel 10 from moving along the axial direction of the cable reel 10, improving the stability of the cable reel 10, and reducing the risk of the cable reel 10 slipping off the support assembly 120.

[0059] The distance between the two cable reel limiting members 124 on each support shaft 121 is adjustable, thus adapting to cable reels 10 of different lengths.

[0060] Specifically, the cable reel limiting member 124 is sleeved on the support shaft 121 and locked with screws. After the screws are removed, the cable reel limiting member 124 can be moved so that the cable reel limiting member 124 can move axially along the support shaft 121. After the position of the cable reel limiting member 124 is adjusted, the cable reel limiting member 124 can be locked on the support shaft 121 again with screws.

[0061] like Figure 4 As shown, in some embodiments, at least one support shaft 121 is movably connected to the base 110 so that the distance between the two support shafts 121 is adjustable.

[0062] It is understandable that when the position of the support shaft 121 connected to the base 110 is adjusted, the distance between the two support shafts 121 can be changed, thereby matching cable reels 10 with different outer diameters, which has a wide range of applications.

[0063] Specifically, one support shaft 121 is defined as the drive shaft, and the drive assembly 130 is driven and connected to the drive shaft. The drive assembly 130 can drive the drive shaft to rotate forward or backward. The other support shaft 121 is defined as the driven shaft. When the drive assembly 130 drives the drive shaft to rotate, it can drive the cable reel 10 to rotate, and the driven shaft will rotate with the cable reel 10 when the cable reel 10 rotates. The driven shaft is movably connected to the base 110, and the driven shaft can be operated to move closer to or further away from the drive shaft.

[0064] Furthermore, the base 110 includes a guide rail 111, the extension direction of which is parallel to the spacing direction of the two support shafts 121. The driven shaft is slidably connected to the guide rail 111, and the guide rail 111 guides the movement of the driven shaft, thereby improving the accuracy of the driven shaft's movement path.

[0065] Specifically, there are two guide rails 111, which are arranged side by side and spaced apart. The spacing between the two guide rails 111 is parallel to the axial direction of the driven shaft, and the two ends of the driven shaft are slidably connected to the two guide rails 111 respectively.

[0066] More specifically, each end of the driven shaft is provided with a slide block 122, and the slide blocks 122 at both ends of the driven shaft are slidably connected to two guide rails 111 respectively.

[0067] Furthermore, the slide 122 is provided with a first pin hole 1221, and the guide rail 111 is provided with a plurality of second pin holes 112. The plurality of second pin holes 112 are spaced apart along the length of the guide rail 111. When the slide 122 moves along the guide rail 111, the first pin hole 1221 can be aligned with any one of the second pin holes 112. After the position of the slide 122 is adjusted, a pin 123 can be inserted through the first pin hole 1221 and the second pin hole 112 to achieve the positioning of the slide 122, thereby preventing the driven shaft from moving arbitrarily and improving stability.

[0068] Of course, in other embodiments, after the position of the driven shaft is adjusted, the position of the driven shaft is also locked by means of other locking mechanisms.

[0069] In some embodiments, a leveling mechanism is also provided on the base 110. The leveling mechanism can level the base 110, thereby ensuring that the two support shafts 121 remain horizontal, which is beneficial to improving the stability of the cable 20 during the cable winding and unwinding process.

[0070] The leveling mechanism can be a hydraulic cylinder or a leveling support leg.

[0071] Furthermore, in order to determine whether the base 110 has been leveled, a level is also installed on the base 110.

[0072] like Figure 4 As shown, in some embodiments, a first lifting ring 113 is also provided on the base 110, so that the entire display device 100 can be lifted and transported. Only two lifting operations are needed (lifting onto the transport vehicle once and lifting off the transport vehicle once) to quickly put it into construction, which can reduce lifting time and lifting costs, and reduce preparation time.

[0073] like Figure 3 As shown, the safety protection device 400 is used to limit the cable reel 10 and reduce the risk of the cable reel 10 overturning or running out.

[0074] Combination Figure 8 and Figure 9 The safety protection device 400 includes a center bar 410, two sets of limit components 430 and two pull bars 440.

[0075] Both ends of the center bar 410 are connected to a rotating ring 420; two sets of limiting components 430 are respectively disposed at both ends of the center bar 410, and the two sets of limiting components 430 are located between the two rotating rings 420 at both ends of the center bar 410; two pull bars 440 pass through the two rotating rings 420 at both ends of the center bar 410 respectively.

[0076] Specifically, the center strip 410 is used to pass through the center hole of the cable reel 10. It can be understood that the center hole of the cable reel 10 extends along the axial direction of the cable reel 10 and passes through both ends of the cable reel 10; the center strip 410 passes through the center hole of the cable reel 10 and makes the two sets of limiting components 430 abut against the two ends of the cable reel 10 respectively; the two ends of the pull strip 440 are fixed on the cable feeding device 100 that carries the cable reel 10.

[0077] Furthermore, the swivel 420 is configured to allow the center bar 410 to rotate relative to the pull bar 440 as it rotates with the cable reel 10.

[0078] Understandably, the cable reel 10 is placed on the support assembly 120. When the drive assembly 130 drives the support assembly 120 to run, it can drive the cable reel 10 to rotate. The safety protection device 400 can limit the cable reel 10 on the support assembly 120. Furthermore, since the swivel ring 420 allows the center bar 410 to rotate relative to the pull bar 440 when rotating with the cable reel 10, the cable reel 10 is limited without affecting its rotation, thereby reducing the risk of the cable reel 10 overturning or slipping out and ensuring construction safety.

[0079] In some embodiments, the limiting assembly 430 includes a position-adjustable limiting unit 431 and a locking member 432 for locking the limiting unit 431 onto the center bar 410; wherein the limiting unit 431 includes a sleeve 4311 that is position-adjustably sleeved on the center bar 410, and a limiting member 4312 that is sleeved on the sleeve 4311 and threadedly connected to the sleeve 4311, the locking member 432 is used to lock the sleeve 4311 onto the center bar 410, and the limiting member 4312 is operable to move axially along the sleeve 4311.

[0080] Understandably, before the locking member 432 locks the position of the sleeve 4311, the sleeve 4311 can move along the length of the center strip 410, thereby moving closer to or further away from the end of the cable reel 10. After the position of the sleeve 4311 is adjusted, the locking member 432 can be used to lock the position of the sleeve 4311, thereby preventing the sleeve 4311 from moving arbitrarily. In addition, after the position of the sleeve 4311 is locked, the limiting member 4312 can be rotated to move along the axial direction of the sleeve 4311, ensuring that the limiting member 4312 is pressed against the end of the cable reel 10, reducing the risk of the cable reel 10 loosening and improving reliability.

[0081] It should be noted that before the locking member 432 locks the position of the sleeve 4311, the sleeve 4311 can be moved along the length of the center bar 410 to achieve coarse adjustment. After the locking member 432 locks the position of the sleeve 4311, the limiting member 4312 can be rotated to move along the axial direction of the sleeve 4311 to achieve fine adjustment, ensuring that the cable reel 10 is limited.

[0082] In some embodiments, the center bar 410 is a center chain, the sleeve 4311 is provided with an assembly hole, and the locking member 432 is detachably inserted into the assembly hole and the hole of the center chain.

[0083] Understandably, the central chain is composed of multiple rings connected in series, each ring having a hole. By inserting the locking member 432 into the mounting hole of the sleeve 4311 and the hole of the central chain, the position of the sleeve 4311 can be locked. Furthermore, by removing the locking member 432, the position of the sleeve 4311 can be further adjusted. In some cases, if the locking member 432, after being inserted into the mounting hole of the sleeve 4311 and the hole of the central chain, cannot ensure that the limiting member 4312 is tightly abutted against the end of the cable reel 10, rotating the limiting member 4312 allows it to move axially along the sleeve 4311, ensuring that the limiting member 4312 is tightly abutted against the end of the cable reel 10 and reducing the risk of the cable reel 10 becoming loose.

[0084] The locking element 432 can be a pin or a screw.

[0085] In some embodiments, the swivel 420 includes a first buckle 421 connected to the end of the center bar 410 and a second buckle 422 rotatably connected to the first buckle 421, with the pull bar 440 passing through the second buckle 422.

[0086] It is understandable that the swivel 420 is a figure-eight swivel, and its first fastening position 421 and second fastening position 422 can rotate relative to each other. In this way, with the center bar 410 connected to the first fastening position 421 and the pull bar 440 passing through the second fastening position 422, the cable reel 10 can be limited without affecting its rotation, thereby reducing the risk of the cable reel 10 overturning or slipping out and ensuring construction safety.

[0087] In some embodiments, the base 110 is provided with a plurality of buckles 140, and both ends of each pull bar 440 are connected to the buckles 140, which are used to fix the pull bar 440.

[0088] Specifically, the pull bar 440 is a pull chain, and the base 110 is provided with four buckles 140, two of which are located at one end of the cable reel 10 and spaced apart, and the other two buckles 140 are located at the other end of the cable reel 10 and spaced apart. The two ends of the pull bar 440 located at one end of the cable reel 10 are respectively connected to the two corresponding buckles 140, and the two ends of the pull bar 440 located at the other end of the cable reel 10 are respectively connected to the two corresponding buckles 140.

[0089] This application also provides a protection method, which includes:

[0090] Step 1: As Figure 6 As shown, the center bar 410 is passed through the center hole of the cable reel 10 placed on the support assembly 120.

[0091] Specifically, the cable reel 10 is first placed on the support assembly 120, and then the center strip 410 is passed through the center hole of the cable reel 10.

[0092] Step Two: As Figure 7 , Figure 8 As shown, limit components 430 are installed at both ends of the center bar 410.

[0093] The step of installing the limit assembly 430 at each end of the center bar 410 includes: fitting the limit unit 431 onto the end of the center bar 410 and making the limit unit 431 abut against the end of the cable reel 10, and then using the locking member 432 to lock the position of the sleeve 4311.

[0094] Specifically, after assembling the limiting member 4312 and the sleeve 4311, the sleeve 4311 is fitted onto the center strip 410, and the limiting member 4312 is as close as possible to the end of the cable reel 10. Then, the position of the limiting unit 431 is locked by the locking member 432. After that, the limiting member 4312 is rotated to press the cable reel 10 against the wall.

[0095] Step 3: As Figure 9 As shown, pull bars 440 are connected to the swivels 420 at both ends of the center bar 410.

[0096] The step of connecting the pull bar 440 to the swivel 420 at each end of the center bar 410 includes: passing the pull bar 440 through the swivel 420 located at the end of the center bar 410 and fixing the pull bar 440 to the base 110.

[0097] In the protection method of the present invention, the cable reel 10 is placed on the support assembly 120. When the drive assembly 130 drives the support assembly 120 to run, it can drive the cable reel 10 to rotate. The safety protection device 400 can lock the cable reel 10 on the support assembly 120. Furthermore, since the swivel ring 420 allows the center bar 410 to rotate relative to the pull bar 440 when rotating with the cable reel 10, the cable reel 10 is limited without affecting its rotation, thereby reducing the risk of the cable reel 10 overturning or slipping out and ensuring construction safety.

[0098] like Figure 2 As shown, the speed regulating device 200 includes a main support 210, an upper pressure monitoring shaft assembly 220 disposed on the main support 210, and a lower pressure monitoring shaft assembly 230 disposed on the main support 210. The upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 are arranged side by side with a gap and are located above the lower pressure monitoring shaft assembly 230.

[0099] Combination Figure 1 and Figure 2 It is understood that the main support 210 is used to support the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230, and the cable 20 on the cable reel 10 can pass through the area between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230. Specifically, when the cable 20 abuts against the upper pressure monitoring shaft assembly 220, the upper pressure monitoring shaft assembly 220 can monitor the pressure value it experiences; when the cable 20 abuts against the lower pressure monitoring shaft assembly 230, the lower pressure monitoring shaft assembly 230 can monitor the pressure value it experiences.

[0100] Combination Figure 10 , Figure 12 and Figure 13During the cable laying process, the cable conveyor at the front end pulls the cable 20. When the laying speed of the laying device 100 is too slow, that is, when the driving speed of the drive assembly 130 driving the support assembly 120 is too slow, causing the cable reel 10 to rotate too slowly in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 will be in a taut state and abut against the upper pressure monitoring shaft assembly 220 (e.g., Figure 13 (As shown); When the cable deployment speed of the deployment device 100 is too fast, that is, when the driving component 130 drives the support component 120 too fast, causing the cable reel 10 to rotate too fast in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 will be in a loose state and abut against the lower pressure monitoring shaft assembly 230 (as shown); Figure 12 (As shown).

[0101] During cable retrieval, if the cable laying speed of the laying device 100 is too slow (i.e., the driving speed of the drive component 130 driving the support component 120 is too slow, causing the cable reel 10 to rotate too slowly in the second rotation direction), the cable 20 passing through the area between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 will be in a loose state and will abut against the lower pressure monitoring shaft assembly 230. If the cable laying speed of the laying device 100 is too fast (i.e., the driving speed of the drive component 130 driving the support component 120 is too fast, causing the cable reel 10 to rotate too fast in the second rotation direction), the cable 20 passing through the area between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 will be in a taut state and will abut against the upper pressure monitoring shaft assembly 220.

[0102] The input of the controller 300 is connected to the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230, and the output of the controller 300 is connected to the drive assembly 130.

[0103] Understandably, the controller 300 can control the drive assembly 130 to drive the support assembly 120 to operate at the speed based on the monitoring results of the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230.

[0104] During the cable laying construction of cable 20:

[0105] The controller 300 can acquire the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230 in real time.

[0106] If the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the first preset value, the controller 300 controls the drive assembly 130 to increase the running speed of the support assembly 120 to increase the cable unloading speed of the cable reel 10. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the second preset value, the controller 300 controls the drive assembly 130 to decrease the running speed of the support assembly 120 to decrease the cable unloading speed of the cable reel 10.

[0107] Understandably, when the cable laying speed of the laying device 100 is too slow, that is, when the driving component 130 drives the support component 120 too slowly, causing the cable reel 10 to rotate too slowly in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a taut state and resist the upper pressure monitoring shaft component 220. The greater the pressure on the upper pressure monitoring shaft component 220, the slower the cable reel 10 rotates in the first rotation direction. If the pressure of the cable 20 on the upper pressure monitoring shaft component 220 is higher than the first preset value, it indicates that the speed of the cable reel 10 rotating in the first rotation direction is lower than the ideal range. At this time, the controller 300 can control the driving component 130 to increase the operating speed of the support component 120 to increase the cable laying speed of the cable reel 10, thereby making the speed of the cable reel 10 rotating in the first rotation direction return to the ideal range.

[0108] When the cable laying speed of the laying device 100 is too fast, that is, when the driving component 130 drives the support component 120 to run too fast, causing the cable reel 10 to rotate too fast in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a loose state and will abut against the lower pressure monitoring shaft component 230. The greater the pressure on the lower pressure monitoring shaft component 230, the faster the cable reel 10 rotates in the first rotation direction. If the pressure of the cable 20 on the lower pressure monitoring shaft component 230 is higher than the second preset value, it indicates that the speed of the cable reel 10 rotating in the first rotation direction is higher than the ideal range. At this time, the controller 300 can control the driving component 130 to reduce the running speed of the support component 120 to reduce the cable laying speed of the cable reel 10, so that the speed of the cable reel 10 rotating in the first rotation direction returns to the ideal range.

[0109] During the cable retrieval process of cable 20:

[0110] The controller 300 can acquire the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230 in real time.

[0111] If the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the third preset value, the control drive assembly 130 reduces the operating speed of the support assembly 120 to reduce the cable reel 10 winding speed. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the fourth preset value, the control drive assembly 130 increases the operating speed of the support assembly 120 to increase the cable reel 10 winding speed.

[0112] Understandably, when the cable winding speed of the deployment device 100 is too fast, that is, when the driving component 130 drives the support component 120 too fast, causing the cable reel 10 to rotate too fast in the second rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a taut state and resist the upper pressure monitoring shaft component 220. The greater the pressure on the upper pressure monitoring shaft component 220, the faster the cable reel 10 rotates in the second rotation direction. If the pressure value on the upper pressure monitoring shaft component 220 is higher than the third preset value, it means that the speed of the cable reel 10 rotating in the second rotation direction is higher than the ideal range. At this time, the controller 300 can control the driving component 130 to reduce the operating speed of the support component 120 to reduce the cable winding speed of the cable reel 10, so that the speed of the cable reel 10 rotating in the second rotation direction returns to the ideal range.

[0113] When the cable winding speed of the deployment device 100 is too slow, that is, when the operating speed of the drive component 130 driving the support component 120 is too slow, causing the cable reel 10 to rotate too slowly in the second rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a loose state and will abut against the lower pressure monitoring shaft component 230. The greater the pressure on the lower pressure monitoring shaft component 230, the slower the cable reel 10 rotates in the second rotation direction. If the pressure value on the lower pressure monitoring shaft component 230 is higher than the fourth preset value, it indicates that the cable reel 10 rotates below the ideal range in the second rotation direction. At this time, the controller 300 can control the drive component 130 to increase the operating speed of the support component 120 to increase the cable winding speed of the cable reel 10, thereby bringing the cable reel 10 back to the ideal range in the second rotation direction.

[0114] It should be noted that the first, second, third, and fourth preset values ​​can be set according to the characteristics of the construction object (cables of different sizes).

[0115] It is understandable that, whether during the cable laying or cable winding process, when the cable 20 is located between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 and is not in contact with either assembly, the cable winding speed is within the ideal range.

[0116] The cable laying device of the present invention can realize automatic speed adjustment during the cable laying process, ensuring that the laying speed of the cable 20 is within the ideal range, thereby protecting the cable 20 during operation and reducing the risk of cable 20 damage.

[0117] Combination Figure 10 and Figure 11 In some embodiments, the upper pressure monitoring shaft assembly 220 includes an upper pressure monitoring shaft 221 mounted on the main support 210 and an upper pressure sensor 222 for detecting the pressure value applied to the upper pressure monitoring shaft 221. The upper pressure sensor 222 is connected to the input terminal of the controller 300. The lower pressure monitoring shaft assembly 230 includes a lower pressure monitoring shaft 231 mounted on the main support 210 and a lower pressure sensor 232 for detecting the pressure value applied to the lower pressure monitoring shaft 231. The lower pressure sensor 232 is connected to the input terminal of the controller 300. The lower pressure monitoring shaft 231 and the upper pressure monitoring shaft 221 are arranged side-by-side and spaced apart, with the lower pressure monitoring shaft 231 located below the upper pressure monitoring shaft 221.

[0118] Understandably, cable 20 can pass through the area between the lower pressure monitoring shaft 231 and the upper pressure monitoring shaft 221, and cable 20 can directly or indirectly abut against the upper pressure monitoring shaft 221 when taut, and can directly or indirectly abut against the lower pressure monitoring shaft 231 when slack. The upper pressure sensor 222 can detect the pressure value of the upper pressure monitoring shaft 221, and the lower pressure sensor 232 can detect the pressure value of the lower pressure monitoring shaft 231. Furthermore, both the upper pressure sensor 222 and the lower pressure sensor 232 can send the detected data to the controller 300 so that the controller 300 can control the operating speed of the drive assembly 130.

[0119] Furthermore, the upper pressure monitoring shaft assembly 220 also includes an upper roller 223 rotatably sleeved on the upper pressure monitoring shaft 221, and the lower pressure monitoring shaft assembly 230 also includes a lower roller 233 rotatably sleeved on the lower pressure monitoring shaft 231. A threading area 240 for the cable 20 to pass through is formed between the upper roller 223 and the lower roller 233, and the pressure of the cable 20 on the upper roller 223 can be transmitted to the upper pressure monitoring shaft 221, and the pressure of the cable 20 on the lower roller 233 can be transmitted to the lower pressure monitoring shaft 231.

[0120] The upper roller 223 is connected to the upper pressure monitoring shaft 221 via the upper bearing 224 at both ends. The upper roller 223 is a deformable component, which allows it to transmit force to the upper pressure monitoring shaft 221 after deformation under stress. The lower roller 233 is connected to the lower pressure monitoring shaft 231 via the lower bearing 234 at both ends. The lower roller 233 is a deformable component, which allows it to transmit force to the lower pressure monitoring shaft 231 after deformation under stress.

[0121] Understandably, the upper roller 223 or the lower roller 233 is used to directly abut against the cable 20. The pressure from the cable 20 on the upper roller 223 can be transmitted to the upper pressure monitoring shaft 221, and the pressure from the cable 20 on the lower roller 233 can be transmitted to the lower pressure monitoring shaft 231. The upper roller 223 and the lower roller 233 also provide support and guidance for the cable 20. Furthermore, the cable 20 can move left and right between the upper roller 223 and the lower roller 233, which is suitable for cable 20 installation needs and reduces the risk of the cable 20 being scratched.

[0122] Furthermore, the distance between the upper roller 223 and the lower roller 233 is greater than the diameter of the cable 20. Thus, when the winding and unwinding speed of the cable 20 is within the ideal range, the cable 20 may not come into contact with the upper roller 223 and the lower roller 233.

[0123] like Figure 10 As shown, in some embodiments, the speed regulating device 200 further includes two side rollers 250 respectively disposed at both ends of the threading area 240, and both side rollers 250 are rotatably engaged with the main support 210.

[0124] Understandably, the side roller 250 can laterally limit the cable 20 to prevent it from detaching from both sides of the threading area 240, thus improving safety. Furthermore, when the side roller comes into contact with the cable 20, it will rotate with the cable 20 as the cable 20 is retracted or extended, reducing the risk of the cable 20 being scratched.

[0125] like Figure 10 As shown, in some embodiments, a second lifting ring 260 is also provided on the main support 210, so that the entire speed regulating device 200 can be lifted and transported. It can be put into construction quickly with only two lifting operations (lifting onto the transport vehicle once and lifting off the transport vehicle once), which can reduce lifting time and lifting costs, and reduce preparation time.

[0126] The present invention also provides a cable laying speed control method, applied to the cable laying equipment described above, the cable laying speed control method comprising:

[0127] (1) During cable laying construction:

[0128] S100, real-time acquisition of the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230;

[0129] S200, if the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the first preset value, the drive assembly 130 is controlled to increase the running speed of the support assembly 120 to increase the cable laying speed of the cable reel 10. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the second preset value, the drive assembly 130 is controlled to decrease the running speed of the support assembly 120 to decrease the cable laying speed of the cable reel 10.

[0130] Specifically, the controller 300 can control the driving component 130 to drive the support component 120 to operate at the speed based on the monitoring results of the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230.

[0131] During the cable laying construction of cable 20:

[0132] The controller 300 can acquire the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230 in real time.

[0133] If the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the first preset value, the controller 300 controls the drive assembly 130 to increase the running speed of the support assembly 120 to increase the cable unloading speed of the cable reel 10. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the second preset value, the controller 300 controls the drive assembly 130 to decrease the running speed of the support assembly 120 to decrease the cable unloading speed of the cable reel 10.

[0134] When the cable laying speed of the laying device 100 is too slow, that is, when the driving component 130 drives the support component 120 too slowly, causing the cable reel 10 to rotate too slowly in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a taut state and resist the upper pressure monitoring shaft component 220. The greater the pressure on the upper pressure monitoring shaft component 220, the slower the cable reel 10 rotates in the first rotation direction. If the pressure of the cable 20 on the upper pressure monitoring shaft component 220 is higher than the first preset value, it indicates that the speed of the cable reel 10 rotating in the first rotation direction is lower than the ideal range. At this time, the controller 300 can control the driving component 130 to increase the operating speed of the support component 120 to increase the cable laying speed of the cable reel 10, thereby making the speed of the cable reel 10 rotating in the first rotation direction return to the ideal range.

[0135] When the cable laying speed of the laying device 100 is too fast, that is, when the driving component 130 drives the support component 120 to run too fast, causing the cable reel 10 to rotate too fast in the first rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a loose state and will abut against the lower pressure monitoring shaft component 230. The greater the pressure on the lower pressure monitoring shaft component 230, the faster the cable reel 10 rotates in the first rotation direction. If the pressure of the cable 20 on the lower pressure monitoring shaft component 230 is higher than the second preset value, it indicates that the speed of the cable reel 10 rotating in the first rotation direction is higher than the ideal range. At this time, the controller 300 can control the driving component 130 to reduce the running speed of the support component 120 to reduce the cable laying speed of the cable reel 10, thereby bringing the speed of the cable reel 10 rotating in the first rotation direction back to the ideal range.

[0136] (2) During cable winding-up construction:

[0137] S100, real-time acquisition of the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230;

[0138] S300, if the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the third preset value, the drive assembly 130 is controlled to reduce the running speed of the support assembly 120 to reduce the cable winding speed of the cable reel 10. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the fourth preset value, the drive assembly 130 is controlled to increase the running speed of the support assembly 120 to increase the cable winding speed of the cable reel 10.

[0139] Specifically, the controller 300 can acquire the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230 in real time.

[0140] If the pressure value received by the upper pressure monitoring shaft assembly 220 is higher than the third preset value, the control drive assembly 130 reduces the operating speed of the support assembly 120 to reduce the cable reel 10 winding speed. If the pressure value received by the lower pressure monitoring shaft assembly 230 is higher than the fourth preset value, the control drive assembly 130 increases the operating speed of the support assembly 120 to increase the cable reel 10 winding speed.

[0141] When the cable winding speed of the deployment device 100 is too fast, that is, when the driving component 130 drives the support component 120 too fast, causing the cable reel 10 to rotate too fast in the second rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a taut state and will abut against the upper pressure monitoring shaft component 220. The greater the pressure on the upper pressure monitoring shaft component 220, the faster the cable reel 10 rotates in the second rotation direction. If the pressure value on the upper pressure monitoring shaft component 220 is higher than the third preset value, it indicates that the speed of the cable reel 10 rotating in the second rotation direction is higher than the ideal range. At this time, the controller 300 can control the driving component 130 to reduce the operating speed of the support component 120 to reduce the cable winding speed of the cable reel 10, thereby bringing the speed of the cable reel 10 rotating in the second rotation direction back to the ideal range.

[0142] When the cable winding speed of the deployment device 100 is too slow, that is, when the operating speed of the drive component 130 driving the support component 120 is too slow, causing the cable reel 10 to rotate too slowly in the second rotation direction, the cable 20 passing through the area between the upper pressure monitoring shaft component 220 and the lower pressure monitoring shaft component 230 will be in a loose state and will abut against the lower pressure monitoring shaft component 230. The greater the pressure on the lower pressure monitoring shaft component 230, the slower the cable reel 10 rotates in the second rotation direction. If the pressure value on the lower pressure monitoring shaft component 230 is higher than the fourth preset value, it indicates that the cable reel 10 rotates below the ideal range in the second rotation direction. At this time, the controller 300 can control the drive component 130 to increase the operating speed of the support component 120 to increase the cable winding speed of the cable reel 10, thereby bringing the rotation speed of the cable reel 10 in the second rotation direction back to the ideal range.

[0143] It is understandable that, whether during the cable laying or cable winding process, when the cable 20 is located between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230 and is not in contact with either of them, the cable winding speed is at an ideal value.

[0144] This application also provides a method of using a cable laying device, which is applied in a cable laying device. The method of using the cable laying device includes:

[0145] S10, the base 110 is pre-leveled using a leveling mechanism.

[0146] S20, hoist the cable reel 10 onto the support assembly 120.

[0147] Furthermore, before hoisting the cable reel 10 to the support assembly 120, the distance between the two support shafts 121 can be adjusted to ensure that the cable reel 10 is supported by the two support shafts 121.

[0148] S30, the center bar 410 is passed through the center hole of the cable reel 10 placed on the support assembly 120.

[0149] S40, upper limit components 430 are installed at both ends of the center bar 410.

[0150] The step of installing the limit assembly 430 at each end of the center bar 410 includes: fitting the limit unit 431 onto the end of the center bar 410 and making the limit unit 431 abut against the end of the cable reel 10, and then locking the position of the limit unit 431 with the locking member 432.

[0151] Specifically, after assembling the limiting member 4312 and the sleeve 4311, the sleeve 4311 is fitted onto the center strip 410, and the limiting member 4312 is as close as possible to the end of the cable reel 10. Then, the position of the sleeve 4311 is locked by the locking member 432. After that, the limiting member 4312 is rotated to press the cable reel 10 against the wall.

[0152] S50, pull bars 440 are connected to the swivels 420 at both ends of the center bar 410, and the pull bars are connected to the support assembly 120.

[0153] The step of connecting the pull bar 440 to the swivel 420 at each end of the center bar 410 includes: passing the pull bar 440 through the swivel 420 located at the end of the center bar 410 and fixing the pull bar 440 to the base 110.

[0154] S60, one end of the cable 20 on the cable reel 10 is passed through the space between the upper pressure monitoring shaft assembly 220 and the lower pressure monitoring shaft assembly 230, and is pulled and transported by the cable conveyor.

[0155] S70, start the drive assembly 130 to drive the support assembly 120 to run so that the cable reel 10 can unload the cable. During the cable unloading process, the controller 300 acquires the pressure value of the upper pressure monitoring shaft assembly 220 and the pressure value of the lower pressure monitoring shaft assembly 230 in real time. If the pressure value of the upper pressure monitoring shaft assembly 220 is higher than the first preset value, the controller 300 controls the drive assembly 130 to increase the running speed of the support assembly 120 to increase the unloading speed of the cable reel 10. If the pressure value of the lower pressure monitoring shaft assembly 230 is higher than the second preset value, the controller 300 controls the drive assembly 130 to decrease the running speed of the support assembly 120 to decrease the unloading speed of the cable reel 10.

[0156] The step of connecting the pull bar 440 to the swivel 420 at each end of the center bar 410 includes: passing the pull bar 440 through the swivel 420 located at the end of the center bar 410 and fixing the pull bar 440 to the base 110.
