DETAILED DESCRIPTION

[0053] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0054] Secondly, it should be noted that in the description of the present application, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.

[0055] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0056] Cable laying refers to the process of laying and installing cables along the explored roads to form cable lines. According to the application scenarios, it can be divided into overhead, underground (pipeline and direct burial), underwater, wall and tunnel laying methods.

[0057] In the existing cable laying equipment, the driving motor is used to pull the cable on the cable drum to improve the cable laying efficiency. In order to improve the service life of the cable, a corresponding curing agent can be applied to the outer surface of the cable during the cable laying process, and the curing agent is basically applied manually.

[0058] However, the cable laying length is long, and the manual application method will result in low application efficiency, affecting the construction efficiency. On the other hand, the application structure of the cable outer surface curing agent of the existing cable laying equipment is generally only suitable for one cable specification, resulting in poor applicability of the cable laying equipment.

[0059] In response to the above problems, an embodiment of the present application provides a cable laying device to solve the problems of low efficiency in applying curing agent to the outer surface of the cable, poor cable laying quality and low construction progress in existing cable laying equipment.

[0060] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0061] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a cable laying device, wherein the cable laying device 100 includes a mobile platform 1 and a surface maintenance structure 2.

[0062] A cable drum 10 is provided on the mobile platform 1, and the cable drum 10 is used to wind cables of various specifications and sizes to be laid (as shown in the figure). It should be noted that the cable can be pulled out of the cable drum 10 by a driving motor, or pulled out of the cable drum 10 in other ways, such as using an electric mobile trolley.

[0063] The mobile platform 1 is made of a rectangular plate structure. The material of the rectangular plate structure is not specifically limited here, and it can be a steel plate, an aluminum plate or an alloy plate.

[0064] A plurality of moving wheels 11 are provided at the bottom of the mobile platform 1. It should be noted that the number of the moving wheels 11 is at least three, that is, the number of the moving wheels 11 can be three, four, five or more. In order to facilitate the movement of the mobile platform 1, a moving handle 12 can also be provided on the mobile platform 1.

[0065] In one example, there are three moving wheels 11, two of which are arranged on the front side of the mobile platform 1, and the front end along the forward direction of the mobile platform 1 is defined as its front side, and the remaining one moving wheel 11 is arranged on the rear side of the mobile platform 1 and is located at the living position. That is to say, the three moving wheels 11 are fixed on the bottom surface of the mobile platform 1 in an isosceles triangle or equilateral triangle arrangement. In order to facilitate the steering of the mobile platform 1, the moving wheel 11 arranged on the rear side of the mobile platform 1 can be a universal wheel. In this example, the moving handle 12 is arranged on the outer edge of the rear side of the mobile platform 1.

[0066] In another example, there are four moving wheels 11. The four moving wheels 11 are arranged in a rectangular array at the four corners of the bottom of the mobile platform 1. Among them, the two moving wheels 11 located at the rear side of the mobile platform 1 are universal wheels to facilitate the steering of the mobile platform 1. Similarly, the moving handle 12 in this example is arranged on the outer edge of the rear side of the mobile platform 1.

[0067] like Figures 1 to 3 Combined with Figure 4 As shown, the surface maintenance structure 2 includes two maintenance application components 21 arranged opposite to each other. The maintenance application component 21 includes a storage component 211 and an application component 212. The storage component 211 is used to store the maintenance agent and can transport the maintenance agent to the application component 212.

[0068] In some examples, the storage element 211 can be a hollow cylinder structure storing curing agent in combination with a push rod and other structures to achieve the delivery of curing agent. The push rod can be driven electrically, such as by a motor; or it can be delivered in the form of a spring structure, for example, the push rod is set inside the cylinder structure, and a spring is set on the push rod, and the elastic potential energy of the spring is used to push the push rod toward the direction of the application element 212, so as to push the curing agent in the cylinder structure onto the application element 212. Of course, in other examples, other forms can also be used to deliver the curing agent, such as spraying or pumping.

[0069] The smearing member 212 is floatingly arranged on the mobile platform 1, and two smearing members 212 arranged opposite to each other jointly form a maintenance channel 23 for the cable on the cable drum 10 to pass through, so as to apply the curing agent to the outer surface of the cable when the cable is pulled. It should be noted that the smearing members 212 arranged opposite to each other refer to that the smearing surface of one smearing member 212 is arranged opposite to the smearing surface of the other smearing member 212.

[0070] It should be noted that the smearing member 212 can be arranged in a floating manner on the mobile platform 1 by adopting a structure in which a vertical rod cooperates with a spring, or can be arranged in a floating manner on the mobile platform 1 by adopting an air fork structure.

[0071] The opposite sides of the smearing member 212 are both provided with arc-shaped grooves 21 a , and the two arc-shaped grooves 21 a are enclosed and combined to form a maintenance channel 23 .

[0072] A curing coating layer 21b is provided in the arc groove 21a, and the outer surface of the curing coating layer 21b can directly contact the outer surface of the cable. The curing coating layer 21b is connected to the outlet end of the storage member 211, so that the curing agent is applied to the outer surface of the cable by the curing coating layer 21b. The curing coating layer 21b can be made of a sponge block.

[0073] In this example, the coating surfaces of the two relatively disposed coating members 212 are in direct contact with the outer surface of the cable, and when the cable on the cable drum 10 is pulled out and passes through the maintenance channel 23, the coating surfaces of the two relatively disposed coating members 212 can directly contact the outer surface of the cable. As the cable moves, the curing agent on the coating surface of the coating member 212 will be evenly coated on the outer surface of the cable, thereby completing the cable laying while achieving the maintenance process of the outer surface of the cable, effectively improving the applicable period of the cable, thereby improving the laying quality of the cable, and ensuring and shortening the construction period of subsequent cable laying.

[0074] On the other hand, since the two relatively disposed smearing members 212 are floatingly disposed, that is, the radial dimension of the maintenance channel formed between the two smearing members 212 can be changed as the diameter of the cable changes. That is, in this example, the floatingly disposed smearing members 212 can be used to apply the curing agent to the outer surface of cables of different specifications and sizes (i.e., different diameters), based on which the applicability of the cable laying device 100 can be effectively improved.

[0075] like Figure 4 As shown, in some embodiments, the surface maintenance structure 2 further includes at least one mounting rod 24 and at least two first elastic members 25 .

[0076] The mounting rod 24 is disposed on the mobile platform 1, wherein one end of the mounting rod 24 can be vertically fixed on the mobile platform 1, and the other end is disposed upward. The number of the mounting rods 24 can be one, two or more. The mounting rod 24 can be a cylindrical rod-shaped structure, or a regular polygonal rod-shaped structure.

[0077] In one example, when there is only one mounting rod 24, two first elastic members 25 are correspondingly sleeved on the mounting rod 24. Two oppositely disposed smearing members 212 are both slidably disposed on the mounting rod 24, and the two smearing members 212 are located between the two first elastic members 25, wherein the first elastic member 25 correspondingly drives the smearing member 212 to float relative to the mobile platform 1.

[0078] In this example, a fixing member can be provided on the top of the mounting rod 24, and the fixing member can be a circular bump or a circular plate, etc., and the diameter of the circular bump or the circular plate is larger than the radial dimension of the mounting rod 24. The circular bump or the circular plate is used to limit the first elastic member 25 located on the upper side. Among them, the side where the first elastic member 25 abuts against the circular bump or the circular plate can be fixedly connected or movably connected. And the side where the first elastic member 25 abuts against the mobile platform 1 can be fixedly connected or movably connected.

[0079] In one example, if Figure 4 As shown, the number of mounting rods 24 is preferably two arranged side by side, and two first elastic members 25 are sleeved on each mounting rod 24, and both ends of the smearing member 212 are respectively slidably arranged on the mounting rods 24. In other words, each smearing member 212 is driven by the two first elastic members 25 to achieve the floating of the smearing member 212 relative to the mobile platform 1.

[0080] Similarly, in this example, a circular bump or a circular plate or other structure is also provided on the top of the mounting rod 24 to ensure the normal use of the first elastic member 25 located on the upper side.

[0081] The first elastic member 25 may include but is not limited to a metal spring or a rubber spring.

[0082] It should be noted that, since the two smearing members 212 are arranged relative to each other in the vertical direction, and the first elastic member 25 on the upper side drives the corresponding smearing member 212 to move downward, the first elastic member 25 on this side does not need to overcome the gravity of the corresponding smearing member 212; the first elastic member 25 on the lower side drives the corresponding smearing member 212 to move upward, and the first elastic member 25 on this side needs to overcome the gravity of the corresponding smearing member 212, therefore, the elastic coefficient of the first elastic member 25 on the upper side can be set to be smaller than the elastic coefficient of the first elastic member 25 on the lower side, so as to ensure the synchronous movement of the smearing members 212 on the upper and lower sides, and then ensure the uniformity of the curing agent application. Of course, the elastic coefficient of the first elastic member 25 on the upper side can also be the same as the elastic coefficient of the first elastic member 25 on the lower side.

[0083] like Figure 4 As shown, in some embodiments, the storage element 211 includes a liquid storage cylinder 2111 and an extruding element 2112 .

[0084] The liquid storage cylinder 2111 is used to store the curing agent, which may include but is not limited to a preservative with an antiseptic effect, an antioxidant with an antioxidative effect, etc. The liquid storage cylinder 2111 is arranged on the side of the smear member 212 away from the curing channel 23. The liquid storage cylinder 2111 adopts an internal hollow cylindrical structure, and a through circular through groove structure is provided at both the upper and lower ends of the liquid storage cylinder 2111. The circular through groove structure at the lower end of the liquid storage cylinder 2111 is connected to the circular through groove structure provided on the smear member 212, thereby realizing direct communication between the liquid storage cylinder 2111 and the curing smear layer 21b.

[0085] The extrusion piece 2112 is partially disposed in the liquid storage cylinder 2111 , and is configured to squeeze the maintenance agent in the liquid storage cylinder 2111 onto the smearing piece 212 , specifically, squeeze the maintenance agent in the liquid storage cylinder 2111 onto the maintenance smearing layer 21 b .

[0086] In this example, the curing agent in the liquid storage cylinder 2111 is evenly applied to the outer surface of the cable by squeezing the extrusion piece 2112, thereby ensuring and improving the laying quality and service life of the cable.

[0087] like Figure 4 As shown, in one example, the extrusion member 2112 includes a connecting rod 211 a , an extrusion plate 211 b , and a second elastic member 211 c .

[0088] One end of the connecting rod 211 a passes through the bottom wall or the top wall of the liquid storage cylinder 2111 through a circular through groove structure on one side of the liquid storage cylinder 2111 , and extends into the liquid storage cylinder 2111 .

[0089] The squeezing plate 211b and the second elastic member 211c are both located inside the liquid storage barrel 2111, the squeezing plate 211b is connected to the connecting rod 211a, the second elastic member 211c is sleeved on the connecting rod 211a, and the two ends of the second elastic member 211c are respectively in contact with the squeezing plate 211b and the inner wall of the liquid storage barrel 2111. It should be noted that the second elastic member 211c is always in a compressed state, so as to use the elasticity of the second elastic member 211c to slowly push the squeezing plate 211b to move, so as to evenly squeeze the curing agent from the liquid storage barrel 2111, and evenly apply the curing agent on the outer surface of the cable through the curing coating layer 21b.

[0090] The second elastic member 211c may include but is not limited to a metal spring and the like.

[0091] Due to the long length of cable laying, some problems will inevitably occur on the outer surface of the cable, such as bulging or cracking of the cable protective layer. Bulging or cracked cables will affect the laying quality and construction progress of the cable, and are not conducive to the maintenance of the outer surface of the cable.

[0092] like Figures 1 to 3 Combined with Figure 5 and Figure 6 As shown, in some embodiments, an appearance detection structure 3 is provided between the line drum 10 and the surface maintenance structure 2. The appearance detection structure 3 includes a fixing rod 31, a limiting ring 32 and a plurality of detection components 33.

[0093] The number of the fixing rods 31 can be one, two or more. For example, taking the number of the fixing rods 31 as two, one end of the two fixing rods 31 is vertically fixed on the mobile platform 1.

[0094] The limiting ring 32 is disposed at the other end of the fixing rod 31 , and a plurality of through holes (not shown in the figure) arranged along the circumference of the limiting ring 32 are disposed on the limiting ring 32 .

[0095] A plurality of detection components 33 are arranged in a circular array on the limit ring 32. The number of through holes is the same as the number of detection components 33, that is, one detection component 33 is correspondingly arranged in each through hole.

[0096] The detection assembly 33 includes a detection rod 331 , a roller 332 , a detection member 333 and an alarm member 334 .

[0097] The detection rod 331 has a first end and a second end. After the second end passes through the through hole, it points to the axial direction of the limiting ring 32. That is, the first end is located on the outside of the limiting ring 32, and the second end is located on the inside of the limiting ring 32.

[0098] The detection rod 331 is provided with a first positioning ring 331a and a second positioning ring 331b, the first positioning ring 331a is located inside the limiting ring 32 and is arranged near the second end, the detection rod 331 is sleeved with a third elastic member 331c, and the third elastic member 331c is located between the first positioning ring 331a and the inner side wall of the limiting ring 32. The second positioning ring 331b is located outside the limiting ring 32 and is arranged near the first end.

[0099] The third elastic member 331c may include but is not limited to a metal spring.

[0100] The roller 332 is rollingly arranged on the second end, that is, the roller 332 can rotate on the second end. The rolling direction of the roller 332 is the same as the moving direction of the cable, and the outer side wall of the roller 332 can abut against the outer surface of the cable. That is, as the cable is pulled out, the roller 332 can roll on the outer surface of the cable. The roller 332 can be made of a circular plate structure.

[0101] The detection member 333 is disposed on the detection rod 331 , and the detection member 333 is configured to detect the distance moved by the detection rod 331 relative to the limit ring 32 when the cable passes through the roller 332 .

[0102] The detection member 333 includes a sensing switch 333 a and a proximity switch 333 b . The sensing switch 333 a is sleeved on the detection rod 331 and is located on the outer side wall of the limiting ring 32 .

[0103] The proximity switch 333b is disposed on the second positioning ring 331b and is disposed toward the induction switch 333a.

[0104] The alarm element 334 is electrically connected to the detection element 333 , and issues a warning indication when the distance moved by the detection rod 331 relative to the limit ring 32 is greater than or less than a preset distance.

[0105] The alarm component 334 may include but is not limited to a buzzer or an audible and visual alarm.

[0106] Specifically, the alarm element 334 is electrically connected to the proximity switch 333 b, and the proximity switch 333 b is used to detect the relative distance between it and the sensing switch 333 a. It should be noted that the relative distance is used to characterize the distance that the detection rod 331 moves relative to the limit ring 32.

[0107] The proximity switch 33b is configured such that when any relative distance is greater than or less than a preset distance, the alarm element 334 issues a warning indication at the same time as the proximity switch 333b is activated.

[0108] After knowing the diameter of the cable on the cable drum 10, the preset distance can be set as the radius of the cable. When the cable is pulled out, if the outer surface of the cable is damaged, when the roller 332 passes through the damaged area, under the elastic action of the third elastic member 331c, the roller 332 will move toward the axis of the limit ring 32, that is, the distance between the detection rod 331 and the limit ring 32 has changed, that is, the relative distance between the proximity switch 333b and the induction switch 333a is smaller than the preset distance.

[0109] If there is a bulge on the outer surface of the cable, when the roller 332 passes through the damaged area, the roller 332 will move away from the axial direction of the limit ring 32, further compressing the third elastic member 331c. At this time, the distance between the detection rod 331 and the limit ring 32 changes, that is, the relative distance between the proximity switch 333b and the sensing switch 333a is greater than the preset distance.

[0110] Therefore, when any relative distance is greater than or less than the preset distance, the proximity switch 333b is activated, and the alarm element 334 is activated at the same time, and a warning indication is issued.

[0111] In this example, by setting the appearance detection structure 3, the appearance of the cable can be promptly detected before the cable is pulled out and surface maintenance is performed, so as to discover quality problems such as damage and cracks on the outer surface of the cable in advance.

[0112] In one example, the alarm component 334 can be electrically connected to a controller (not shown in the figure) that controls the cable to be pulled out. When the alarm component 334 issues a warning indication, the controller synchronously controls the drive motor that drives the cable to stop running, so as to facilitate the staff to process the appearance of the cable and avoid rework after the laying of cables of unqualified quality. This is conducive to good control of the cable construction refrigeration and ensure the progress of subsequent cable construction.

[0113] like Figures 1 to 6 As shown, the use process of the cable laying device 100 in the above example is as follows:

[0114] The cable is pulled out from the cable drum 10 under the action of the driving motor and other equipment. After the appearance inspection of the appearance inspection structure 3, when it is pulled between the two smearing members 212, the two smearing members 212 move toward each other under the elastic action of the first elastic member 25, thereby driving the maintenance smearing layer 21b to fit and contact the outer surface of the cable. Then, under the elastic action of the second elastic member 211c, the extrusion plate 211b is pushed to press the curing agent in the liquid storage cylinder 2111, so that the curing agent can penetrate into the curing smearing layer 21b, and the curing agent is applied to the outer surface of the cable through the curing smearing layer 21b, so as to achieve the maintenance treatment of the outer surface of the cable, so that the maintenance construction process of the outer surface of the cable can be automatically completed while realizing the cable laying and automatic appearance inspection of the outer surface of the cable, reducing the workload of the staff for subsequent maintenance, thereby effectively ensuring the construction quality and progress of the cable laying.
