[0043] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0046] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] In one aspect of the embodiments of the present application, a diskless cable laying device is provided. Figure 1 As shown, in some embodiments, the diskless cable laying device includes a rotating mechanism 10, a telescopic assembly 20 and a controller, the telescopic assembly 20 is arranged on the rotating mechanism 10, the rotating mechanism 10 is used to drive the telescopic assembly 20 to rotate, and the telescopic assembly 20 is used to support the cable 40; the telescopic assembly 20 includes a pressure sensor, and the pressure sensor is used to detect the pressure of the cable 40 acting on the telescopic assembly 20; the controller and the pressure sensor are electrically connected, and when the pressure is greater than a preset value, the controller controls the telescopic assembly 20 to retract.

[0048] Specifically, Figure 1 and 2As shown, the rotating mechanism 10 is disposed on the supporting mechanism 30, and the rotating mechanism 10 can rotate around the supporting mechanism; further, the rotating mechanism 10 can rotate 360 ​​degrees around the supporting mechanism 30. The rotating mechanism 10 can be made of metal such as steel or aluminum alloy, which can play a role in stable support and stable rotation. Figure 1 and 2 As shown, the support mechanism 30 is generally arranged on the ground, so that the support structure 30 can provide a stable support function; the support mechanism 30 can be made of metal such as steel or aluminum alloy.

[0049] In the embodiment of the present application, the telescopic assembly 20 mainly plays the role of supporting the cable during the cable 40 release process, which can prevent the cable 40 from being damaged during the release process. The telescopic assembly 20 is fixedly connected to the rotating mechanism 10 by welding or the like; for example, the telescopic assembly 20 can also be detachably connected to the rotating mechanism 10 by nuts and bolts or the like, which is conducive to facilitating the disassembly and assembly of the telescopic assembly 20. The telescopic assembly 20 can be made of metal such as steel or aluminum alloy. The telescopic assembly 20 can be a telescopic mechanism with telescopic and supporting functions (for example, the telescopic assembly 20 can be a telescopic rod with telescopic and supporting functions of the cable 40), which can make the cable be subjected to balanced and moderate pressure during the cable release process.

[0050] In the embodiment of the present application, the pressure sensor mainly provides the pressure condition of the cable during the process of laying out the cable 40. By electrically connecting the controller and the pressure sensor, the extension or retraction state of the telescopic assembly 20 can be adjusted in real time according to the pressure condition of the cable, so that the cable can maintain a moderate tightness to prevent the cable from being in an overly tight state due to excessive pressure; or, it can also prevent the cable from being in an overly relaxed state due to too little pressure, thereby making the cable 40 that has not been laid out in a relaxed state and prone to entanglement or even tangling, which can easily cause damage to the cable in serious cases, and also seriously affect the efficiency of the cable laying construction.

[0051] In the actual cable laying process, the pressure value of the cable is kept within the range of 80-150Pa, which can prevent the cable from being over-tightened or over-relaxed, which seriously affects the laying quality. For example, when the pressure sensor shows that the pressure on the cable is greater than a preset value (for example, the preset value is 150Pa), the controller can control the telescopic assembly 20 to retract in real time, so that the cable can be kept at an appropriate tightness.

[0052] For example, Figure 2As shown, in actual application scenarios, the radius of the cable 40 changes continuously as the cable is released, causing the pressure on the cable to decrease continuously, making the cable 40 to be released prone to excessive relaxation, and thus making it easy for the cable 40 to be released to get entangled or even tangled. Therefore, when the pressure sensor shows that the pressure on the cable is less than the lower pressure limit (for example, the lower pressure limit is 80Pa), the controller can control the telescopic assembly 20 to extend forward in real time and apply pressure to the cable, so that the cable always maintains a suitable tightness, which can effectively improve the cable release quality.

[0053] The diskless cable laying device provided in the embodiment of the present application is arranged on the inner side of the cable during the cable laying process, applies supporting pressure to the cable through the telescopic component 20, and the stress condition of the cable can be obtained in real time through the pressure sensor; at the same time, when the pressure is greater than the preset value, the controller can control the telescopic component 20 to retract, effectively preventing the cable from being damaged due to excessive tension during the laying process.

[0054] like Figure 1 and 2 As shown, in some embodiments, the telescopic assembly 20 includes two telescopic members 201 and two trays 202, the telescopic member 201 is arranged on the support sleeve 203, the support sleeve 203 is arranged on the rotating mechanism 10, and the two trays 202 are respectively arranged at both ends of the telescopic member 201. The two trays 202 are used to support the cable 40, and the two telescopic members 201 can drive the two trays 202 to apply pressure to the cable 40, so that the cable 40 is always kept at a suitable tightness. The two trays 202 are respectively arranged at the front ends of the two telescopic members 201, and the telescopic movement of the two telescopic members 201 can drive the two trays 202; further, the two trays 202 are symmetrically arranged above and below the support structure 30, so that the two trays 202 can apply balanced pressure to the cable 40, so that the tightness of the cable 40 is more balanced, and the cable 40 laying process can be smoother.

[0055] In the embodiment of the present application, the tray 202 of the telescopic assembly 20 can be made of metal such as steel or aluminum alloy. The telescopic member 201 can be detachably connected to the rotating mechanism 10 by means of nuts and bolts, etc., which is conducive to the disassembly and assembly of the telescopic member 201. The tray 202 is connected to the front end of the telescopic member 201 by means of nuts, bolts or buckles, etc., which is conducive to the disassembly and assembly of the tray 202.

[0056] like Figure 1 and 2As shown, in some embodiments, the telescopic assembly 20 also includes a motor 204, which is arranged on the rotating mechanism 10, and the motor 204 is connected to the telescopic member 201, and the motor 204 is used to drive the telescopic member 201 to extend and retract. The motor 204 and the telescopic member 201 can be pivoted. Specifically, the motor 204 is connected to the controller, and the driving state of the telescopic member 201 by the motor 204 can be controlled in real time by the controller. For example, when the pressure on the cable 40 is greater than the preset value, the controller controls the motor 204 in real time, so that the motor 204 can drive the telescopic member 201 to retract, so that the cable can always maintain a suitable tightness; for another example, when the pressure on the cable is less than the preset value, the controller controls the motor 204 in real time, so that the motor 204 can drive the telescopic member 201 to extend forward, so that the cable can always maintain a suitable tightness.

[0057] like Figure 1 and 2 As shown, in some embodiments, the telescopic member 201 includes a first telescopic rod 2011 and a second telescopic rod 2012, and the first telescopic rod 2011 and the second telescopic rod 2012 are respectively movably connected to corresponding motors 204. The first telescopic rod 2011 and the second telescopic rod 2012 can be made of metals such as steel or aluminum alloy. Further, two trays 202 are respectively arranged at the front end of the first telescopic rod 2011 and the front end of the second telescopic rod 2012, and each motor 204 can drive the corresponding first telescopic rod 2011 and the second telescopic rod 2012 to extend and retract, so that the first telescopic rod 2011 and the second telescopic rod 2012 drive the two trays 202 to apply pressure to the cable.

[0058] like Figure 1 and 2 As shown, in other embodiments, the first telescopic rod 2011 includes a first connecting rod 20111, a second connecting rod 20112 and a first limiting sleeve 20113. One end of the second connecting rod 20112 is movably connected to the first motor 2041, the other end of the second connecting rod 20112 is connected to one end of the first connecting rod 20111, the other end of the first connecting rod 20111 is connected to the first tray 2021, and the first connecting rod 20111 is inserted into the first limiting sleeve 20113; for example, one end of the second connecting rod 20112 can be pivotally connected to the first motor 2041, the other end of the second connecting rod 20112 can be pivotally connected to one end of the first connecting rod 20111, and the other end of the first connecting rod 20111 can be detachably connected to the first tray 2021 by nuts and bolts. The first motor 2041 can drive the first connecting rod 20111 to extend and retract, thereby driving the first tray 2021 to retract or extend. The first motor 2041 may be pivotally connected to the second connecting rod 20112 via a connecting rod.

[0059] like Figure 1 and 2As shown, in other embodiments, the second telescopic rod 2012 includes a third connecting rod 20121, a fourth connecting rod 20122 and a second limiting sleeve 20123. One end of the fourth connecting rod 20122 is movably connected to the second motor 2042, the other end of the fourth connecting rod 20122 is connected to one end of the third connecting rod 20121, the other end of the third connecting rod 20121 is connected to the second tray 2022, and the third connecting rod 20121 is inserted into the second limiting sleeve 20123.

[0060] For example, one end of the fourth connecting rod 20122 can be pivotally connected to the second motor 2042, the other end of the fourth connecting rod 20122 can be pivotally connected to one end of the third connecting rod 20121, and the other end of the third connecting rod 20121 can be detachably connected to the second tray 2022 by means of nuts and bolts. The fourth connecting rod 20122 can be driven to extend and retract by the second motor 2042, thereby driving the second tray 2022 to retract or extend. The second motor 2042 can be pivotally connected to the fourth connecting rod 20122 through a connecting rod.

[0061] like Figure 1 and 2 As shown, in some embodiments, the diskless cable laying device further includes a support mechanism 30, and the rotating mechanism 10 includes a first shell 101 and a second shell 102, the first shell 101 and the second shell 102 are rotatably connected to the support mechanism 30, and the first shell 101 is used to drive the telescopic assembly 20 to rotate. In the embodiment of the present application, the first shell 101 and the second shell 102 can be made of metal such as steel or aluminum alloy, which can play a role of stable support and provide stable rotation. Further, the rotatable angle of the first shell 101 is 360 degrees.

[0062] In the embodiment of the present application, the limiting sleeve 203 is detachably connected to the first housing 101 by means of nuts and bolts. Figure 1 As shown, a rotating space is provided between the second housing 102 and the support mechanism 30, and a rotor 103 is provided in the rotating space. Seals are provided at both ends of the second housing 102 to keep the rotor 103 rotating in the rotating space and prevent it from falling out. The second housing 102 can be rotated around the support mechanism 30 by the rotor 103. For example, Figure 1 and 2 As shown, in the actual cable pay-out process, when the cable is pulled forward to pay-out, the cable 40 and the second housing 102 can be synchronously rotated around the support mechanism, so that the cable is properly relieved of stress, which is beneficial to the cable pay-out quality.

[0063] like Figure 1As shown, in some embodiments, the second housing 102 is inserted into the first housing 101, and the first housing 101 can slide left and right along the axial direction of the second housing 102, and the first housing 101 is used to drive the telescopic assembly 20 to slide along the axial direction of the support mechanism 30. In the embodiment of the present application, the first housing 101 slides left and right relative to the second housing 102, so that the first housing 101 can drive the telescopic assembly 20 to move left and right; for example, in the actual process of laying out the cable 40, according to the predetermined laying path of the cable 40, the first housing 101 can be manually slid left and right relative to the second housing 102, and the telescopic assembly 20 can be translated left and right to make the cable 40 constantly adapt to the preset laying path, so as to improve the laying quality of the cable 40.

[0064] In other embodiments, a slide groove is provided along the axial direction of the outer circumference of the second shell 102, and a protrusion is provided on the inner surface of the first shell 101, and the outer dimensions of the protrusion are adapted to the slide groove, and the protrusion can slide left and right in the slide groove; further, a group of slide grooves are provided along the axial direction of the outer circumference of the second shell 102, and correspondingly, a group of protrusions are provided on the inner surface of the first shell 101, and a group of protrusions can slide in the group of slide grooves. In the actual positioning cable laying scenario, the first shell 101 can be manually slid left and right along the axial direction of the second shell 102, thereby driving the telescopic assembly 20 to translate left and right.

[0065] like Figure 1 and 2 As shown, in some embodiments, the support mechanism 30 includes a first support frame 301, a second support frame 302 and a third support frame 303, and the second support frame 302 and the third support frame 303 are respectively connected to the two ends of the first support frame 301. The first support frame 301, the second support frame 302 and the third support frame 303 can all be made of metals such as steel or aluminum alloy, and can provide stable support during the cable laying construction process. Specifically, the two trays 202 are symmetrically arranged above and below the first support frame 301, so that the two trays 202 can apply balanced pressure to the cable; the second shell 102 and the first support frame 301 are rotatably connected, and the second shell 102 can rotate 360 ​​degrees around the first support frame 301.

[0066] The diskless cable laying device provided in the aforementioned embodiment of the present application can adjust the support pressure exerted on the cable in real time during the actual cable laying construction process, so that the cable is in a suitable tightness in real time, effectively avoiding damage to the cable due to excessive tension during the laying process, and improving the laying quality of the cable.

[0067] Another aspect of the embodiment of the present application further provides a construction method of the diskless cable laying device provided in the above embodiment, the construction method comprising:

[0068] Step 1: Place the diskless cable laying device at the center of the inner side of the cable 40;

[0069] Step 2: Make the telescopic assembly 20 apply pressure to the cable;

[0070] Step 3: When the pressure is greater than a preset value, the telescopic assembly 20 is retracted.

[0071] In the embodiment of the present application, before the cable is released, the cable laying device without a reel is placed at the center of the inner side of the cable 40, and a supporting pressure is applied to the cable through the telescopic component 20, so that the cable can be subjected to a balanced supporting pressure when the cable is pulled to release; at the same time, the cable 40 to be released can be placed in a state of balanced force, which can prevent the cable 40 to be released from being entangled or even tangled. During the release process, when the supporting pressure on the cable is greater than the preset value, the telescopic component 20 is retracted, and the tightness of the cable 40 can be adjusted in real time, effectively preventing the cable 40 from being damaged due to excessive tension.

[0072] It should be noted that before the cable is released, the telescopic assembly 20 is in a fully retracted state, and at this time the entire device can be smoothly placed inside the cable 40.

[0073] In some embodiments, the step of placing the trayless cable laying device at a central location inside the cable 40 includes:

[0074] Place two trays 202 at the center of the inner side of the cable 40, and allow the two trays 202 to apply pressure to the cable;

[0075] When the pressure is greater than a preset value, the two trays 202 are retracted.

[0076] Specifically, Figure 1 and 2 As shown, by symmetrically placing the first tray 2021 and the second tray 2022 at the center of the inner side of the cable 40, the first tray 2021 and the second tray 2022 can apply a balanced supporting pressure to the cable, so that the tightness of the cable can be more balanced during the laying process. When the pressure is greater than a preset value, the first motor 2041 and the second motor 2042 are controlled in real time by the controller to drive the first tray 2021 and the second tray 2022 to retract respectively, so that the cable maintains a suitable tightness.

[0077] like Figure 2 As shown, in other embodiments, the step of placing the trayless cable laying device at the center position inside the cable 40 also includes:

[0078] Place two trays 202 at the center of the inner side of the cable 40, and allow the two trays 202 to apply pressure to the cable;

[0079] When the pressure is less than the lower pressure limit, the two trays 202 are extended forward.

[0080] Specifically, Figure 1 and 2 As shown, in the actual cable pay-out process, the radius of the cable 40 changes continuously as the pay-out of the cable 40 proceeds, so that when the pressure on the cable 40 is less than the lower limit of the pressure, the cable 40 to be paid-out is prone to excessive relaxation, and thus the cable 40 to be paid-out is prone to entanglement or even knotting. When the pressure is less than the lower limit of the pressure, the first motor 2041 and the second motor 2042 are controlled in real time by the controller to respectively drive the first connecting rod 20111 and the third connecting rod 20121 to continue to extend forward, and drive the first tray 2021 and the second tray 2022 to continue to apply supporting pressure to the cable so that the cable maintains a suitable tightness.

[0081] like Figure 1 and 2 As shown, in some other embodiments, the construction method further includes translating the cable 40 to be laid out left and right so that the cable 40 is always arranged along a predetermined laying path.

[0082] In the actual cable 40 payout scenario, the cable 40 to be paid out is easily deviated from the predetermined payout path due to the swing of the cable 40, and the cable 40 to be paid out can be arranged along the predetermined payout path by the left-right translation of the cable 40 to be paid out, thereby ensuring the payout quality of the cable 40. Specifically, the first housing 101 is slid left-right along the axial direction of the second housing 102, so that the first housing 101 drives the left-right translation of the cable 40 to be paid out.

[0083] The present application is described in detail below through specific embodiments; however, the embodiments of the present application are not limited to the following specific embodiments and can be appropriately modified and implemented within the scope of the unchanged main rights.

[0084] Embodiment 1

[0085] like Figure 1 and 2 As shown, embodiment 1 provides a construction method of the diskless cable laying device based on the above embodiment, comprising the following steps:

[0086] The device is placed to place the diskless cable laying device at the inner center of the cable 40 to be laid, ensuring that the cable 40 to be laid will not be in a loose state after the device is operated.

[0087] The first motor 2041 and the second motor 2042 are started to respectively drive the first connecting rod 20111 and the third connecting rod 20121 to extend forward, so that the first tray 2021 and the second tray 2022 simultaneously apply supporting pressure to the cable. When the cable is tight, the first motor 2041 and the second motor 2042 are stopped from rotating, and the cables scattered outside the first tray 2021 and the second tray 2022 are adjusted into the first tray 2021 and the second tray 2022, so that the first tray 2021 and the second tray 2022 are against the cable 40 to be laid out, so that the cable 40 is evenly stressed.

[0088] Restart the first motor 2041 and the second motor 2042, and after ensuring that all cables 40 are in the first tray 2021 and the second tray 2022 after the device is running, restart the first motor 2041 and the second motor 2042 to drive the first connecting rod 20111 and the third connecting rod 20121 respectively, so that the first tray 2021 and the second tray 2022 continue to apply supporting pressure to the cables; at the same time, monitor the pressure on the cables 40 in real time through the pressure sensor, so that the cables 40 maintain a moderate tightness to avoid excessive tension of the cables 40.

[0089] Cable pay-out: When the cable 40 is at a moderate tightness, pull the cable 40 and keep the first motor 2041 and the second motor 2042 in operation at the same time, so that the cable 40 is arranged along a predetermined pay-out path, and the stress condition of the cable is monitored and adjusted in real time through a pressure sensor; at the same time, straighten the cable 40 during the pay-out process to avoid bending, crossing and other undesirable conditions of the cable, and keep the pressure value on the cable within the range of 80 to 150 Pa.

[0090] When the pressure on the cable is greater than 150Pa, the controller controls the first motor 2041 and the second motor 2042 to operate, and the first connecting rod 20111 and the third connecting rod 20121 are retracted to keep the cable at a moderate tightness. When the pressure on the cable is less than 80Pa, the controller controls the first motor 2041 and the second motor 2042 to operate, and the first connecting rod 20111 and the third connecting rod 20121 continue to extend forward, so that the first tray 2021 and the second tray 2022 continue to apply supporting pressure to the cable to keep the cable at a moderate tightness.
