Description

Technical Field

[0001] This invention relates to the field of power engineering technology, specifically to a cable laying device and method for power engineering. Background Technology

[0002] Cable laying equipment is a specialized device used in power engineering to lay, install, and secure cables along a predetermined path. In power engineering construction, the quality of cable laying directly affects the operational stability and safety of the power system.

[0003] According to a public disclosure of a cable laying device for power engineering (publication number: CN112290463A), the device includes a support frame, an internal winding drum, and a limiting plate connected to the outside of the winding drum. A sliding plate is located at the bottom of the limiting plate, and a support rod is sleeved inside the sliding plate, with the support rod located inside the support frame. A gear is located above the support rod, and a rotating gear is connected between the gears. A rotating shaft is inserted inside the rotating gear. An electric telescopic rod is installed outside the limiting plate and is located inside the support frame. A protective plate is provided between the winding drums. This cable laying device for power engineering uses a drive gear to drive a driven gear, which in turn drives an output shaft, which in turn drives the winding drum. The rotation of the winding drum winds and unwinds the cable, changing the previous manual winding and unwinding work mode and reducing labor intensity.

[0004] The aforementioned application utilizes a transmission mechanism of driving and driven gears to automate cable winding and unwinding operations, effectively reducing manual labor intensity. However, this device still has the following limitations in practical applications: the tension adjustment of its winding drum relies on a single control of an electric telescopic rod, making it difficult to adapt to the differentiated tension requirements of cables of different specifications; the device lacks real-time pressure monitoring and pressure loss warning functions, failing to promptly interrupt operations when the transmission pressure is abnormal, posing a safety hazard; and the guiding mechanism of the aforementioned device adopts a fixed design, making it difficult to achieve flexible multi-angle turning in complex construction environments, resulting in overly simplistic and impractical designs. Therefore, we propose a cable laying device for power engineering. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cable laying device and method for power engineering, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable laying device for power engineering, comprising a frame and casters. The bottom of the frame is fixedly connected to the fixed end of the casters. A support frame is fixedly connected to the top of the frame. A winding wheel is provided on the top of the support frame. A distribution box is provided on the side of the support frame. An adjustable front-end pressure roller is fixedly connected to the top of the frame. A guide plate is fixedly connected to the top of the frame.

An adaptive cable conveying device is provided on the top of the frame. A handheld guide device is provided on the top of the frame. A pressure loss warning device is provided on the top of the frame.

[0007] The adaptive cable conveying device includes a conveying support plate, which is fixedly connected to the top of the frame. A side mounting plate is screwed to the side of the conveying support plate. An adjusting screw is threaded through and threaded to the top of the side mounting plate. A height slider is slidably connected through and to the side of the side mounting plate. An adjusting shaft is rotatably connected through and to the side of the height slider. A first transmission roller is provided on the inner side of the side mounting plate. A rear fixing plate is fixedly connected to the top of the side mounting plate. A pressure spring is fixedly connected to the side of the rear fixing plate. A front movable plate is fixedly connected to the end of the pressure spring away from the rear fixing plate. A front pressure roller shaft is rotatably connected through and to the bottom of the front movable plate. A first limiting guide post is fixedly connected to the side of the front movable plate. A rear spring fixing plate is fixedly connected to the inner side of the side mounting plate. A tension spring is fixedly connected to the side of the spring fixing plate. A front tension adjusting plate is fixedly connected to the end of the tension spring away from the rear spring fixing plate. A tension roller shaft is rotatably connected through the inner side of the front tension adjusting plate. A friction synchronous belt is sleeved on the circumferential surface of the tension roller shaft. A second limiting guide post is fixedly connected to the side of the front tension adjusting plate. A motor base is screwed to the side of the side mounting plate. A drive motor is fixedly connected to the top of the motor base. A driving bevel gear is fixedly connected to the output shaft of the drive motor. A transmission support plate is fixedly connected to the inner side of the side mounting plate. A transmission shaft is rotatably connected through the side of the transmission support plate. A synchronous pulley is fixedly connected to the circumferential surface of the transmission shaft. A driven bevel gear is fixedly connected to one end of the transmission shaft. A rear guide ring is fixedly connected to the inner side of the side mounting plate.

[0008] According to the above technical solution, a rear protective cover is fixedly connected to the side of the side mounting plate, and a gear protective cover is fixedly connected to the inner side of the side mounting plate. The rear spring fixing plate, tension spring, and front tension adjusting plate are located inside the rear protective cover. The driving bevel gear and the driven bevel gear mesh with each other and are located inside the gear protective cover. The drive motor drives the driving bevel gear to rotate, and the driving bevel gear drives the driven bevel gear to rotate, thereby realizing the conveying of the cable. The pressure spring and the tension spring apply pressure to the front movable plate and the front tension adjusting plate respectively, so that the front pressure roller shaft and the tension roller shaft can closely fit the cable, ensuring the stability and reliability of the conveying. The first limit guide post and the second limit guide post limit the movement of the front movable plate and the front tension adjusting plate respectively, preventing them from deviating or falling off.

[0009] According to the above technical solution, the axes of the first transmission roller, the front pressure roller shaft, and the tension roller shaft are parallel to each other, and the friction synchronous belt is connected to each shaft for transmission. The synchronous pulley meshes with the inner side of the friction synchronous belt. The number of the compression springs is set in two groups, in pairs, and they are symmetrical to each other along the vertical central axis of the side mounting plate. The number of the tension springs and the second limiting guide post is set in three groups, and they are linearly arrayed along the side of the rear spring fixing plate. The adaptive cable conveying device can automatically adjust the conveying pressure and tension according to different specifications of cables, ensuring that the cable will not be excessively squeezed or stretched during the conveying process, effectively protecting the cable from damage. The rear protective cover and gear protective cover prevent dust and debris from entering the device and extend the service life of the device.

[0010] According to the above technical solution, one end of the adjusting screw abuts against the height slider, the circumferential surface of the first limiting guide post penetrates and slides through the side of the rear fixed plate, the circumferential surface of the second limiting guide post penetrates and slides through the side of the rear spring fixed plate, and the number of the adaptive cable conveying device is set to two sets, which are symmetrical to each other along the vertical central axis of the frame, and can simultaneously adaptively convey two cables of different specifications or different directions, thereby improving the efficiency and flexibility of cable laying.

[0011] According to the above technical solution, the handheld guiding device includes a guide base, which is fixedly connected to the top of the frame. A connecting plate is fixedly connected to the top of the guide base, and a guide roller is fixedly connected to the top of the connecting plate. A rotating chassis is fixedly connected to the top of the rotating chassis, and a rotating shaft is rotatably connected through the top of the rotating chassis. A guide chassis is fixedly connected to the end of the rotating shaft away from the rotating chassis. A handle is fixedly connected to the side of the guide chassis, and a rear guide roller is rotatably connected through the top of the guide chassis. An angle adjustment plate is fixedly connected to the top of the guide chassis, and an auxiliary roller is rotatably connected through the inner wall of the angle adjustment plate. The handheld guiding device, through the cooperation of the guide roller and the rear guide roller, achieves preliminary guidance and support for the cable to meet the needs of different laying angles.

[0012] According to the above technical solution, the auxiliary rollers are arranged in several groups and are linearly arrayed along the inner side of the angle adjustment plate. The rear guide rollers, angle adjustment plates and rotating shafts are arranged in two groups and are symmetrical to each other along the vertical central axis of the guide chassis, which can accurately control the direction of the cable in complex environments.

[0013] According to the above technical solution, the pressure loss warning device includes a warning support plate, which is fixedly connected to the top of the frame. A warning slider is slidably connected to the inner side wall of the warning support plate. A main hook is fixedly connected to the side of the warning support plate. A top rod is fixedly connected to the bottom of the warning slider. An installation groove is opened on the side of the warning support plate. A micro switch is fixedly connected to the bottom of the installation groove. An audible and visual alarm is provided on the side of the warning support plate. A tensioning strap is connected to the side of the main hook. A secondary hook is fixedly connected to the side of the warning slider. A contact roller is fixedly connected to the side of the warning slider. When all the cables on the winding wheel are laid, the tension of the winding wheel on the cables disappears, thereby triggering the micro switch and activating the audible and visual alarm to issue a warning signal, reminding the operator to stop the device operation in time and perform cable replacement or other corresponding operations.

[0014] According to the above technical solution, a tensioning strap is connected between the main hook and the auxiliary hook. The trigger end of the micro switch is located on the displacement trajectory of the top rod away from the warning slider. The audible and visual alarm simultaneously emits a high-frequency alarm and flashing light to ensure that operators can detect abnormalities in a timely manner even in noisy construction environments.

[0015] According to the above technical solution, the circumferential surface of the top rod is slidably connected to the inner bottom of the warning support plate. The number of warning support plates, warning sliders and tightening straps are set in two sets, and they are symmetrical to each other along the vertical central axis of the frame. The two sets of pressure loss warning devices can immediately trigger the alarm to avoid the interruption of the overall construction due to a single line failure.

[0016] A method for laying a cable laying device for power engineering includes the following steps: S1: The operator moves the frame to the starting position, adjusts the direction and adjusts the conveying device to accommodate the cable specifications; S2: The conveyor automatically presses and adjusts the tension, and the hand-held guide device guides the cable to be laid along the preset path; S3: When the cable is used up, an audible and visual alarm is triggered. After the operator replaces the winding reel, the cable laying status is restored.

[0017] This invention provides a cable laying device and method for power engineering. It has the following beneficial effects: (1) The present invention enables the adaptive cable conveying device to automatically adjust the conveying pressure and tension according to different specifications of cables, thereby improving the flexibility and adaptability of cable laying. When facing cables of different diameters and materials, the device ensures that the front pressure roller shaft and tension roller shaft can fit tightly and appropriately against the cable through the synergistic action of the compression spring and tension spring. This avoids cable damage caused by excessive compression and prevents cable loosening or falling off due to insufficient tension. The setting of the first limit guide post and the second limit guide post further enhances the stability and reliability of the device, effectively preventing the risk of component displacement or falling off, thereby ensuring the smooth progress of cable laying work.

[0018] (2) The present invention enables operators to flexibly adjust the cable route according to actual laying requirements by setting a hand-held guide device. As long as the handle is rotated to drive the guide base to rotate, the rear guide roller and auxiliary roller can be adjusted synchronously. This design allows the cable to remain smooth when laying in turns or complex paths, avoiding damage to the internal core due to excessive bending. The continuous support structure formed by multiple sets of auxiliary rollers effectively disperses the lateral pressure on the cable and extends the cable service life. It is particularly suitable for precise wiring operations in space-constrained scenarios such as substations and tunnels.

[0019] (3) By setting up a pressure loss warning device, the present invention enables the cable to gradually decrease in the amount of cable on the winding wheel until it is completely laid during the cable laying process. As the cable is gradually reduced until it is completely laid, the tension of the cable on the tensioning strap in the pressure loss warning device will decrease synchronously until it disappears. The warning slider moves downward under its own weight or the tension of the tensioning strap, which drives the top rod to move downward synchronously. When the end of the top rod away from the warning slider touches and presses down the trigger end of the micro switch, the circuit is turned on and the sound and light alarm is triggered to work. The high-frequency alarm sound and the flashing of the strong light occur synchronously, forming a dual visual and auditory warning effect. This realizes timely feedback on the cable exhaustion status and effectively avoids the construction interruption or equipment idling problem caused by failure to replace the cable in time.

[0024] The adaptive cable conveying device 10 includes a conveying support plate 101, which is fixedly connected to the top of the frame 1. A side mounting plate 102 is screwed to the side of the conveying support plate 101. An adjusting screw 103 is threaded through the top of the side mounting plate 102 and threadedly connected to it. A height slider 104 is slidably connected through the side of the side mounting plate 102. An adjusting shaft 105 is rotatably connected through the side of the height slider 104. A first transmission roller 1 is provided on the inner side of the side mounting plate 102. 06. A rear fixing plate 107 is fixedly connected to the top of the side mounting plate 102. A compression spring 108 is fixedly connected to the side of the rear fixing plate 107. A front movable plate 109 is fixedly connected to the end of the compression spring 108 away from the rear fixing plate 107. A front pressure roller shaft 110 is rotatably connected through the bottom of the front movable plate 109. A first limiting guide post 126 is fixedly connected to the side of the front movable plate 109. A rear spring fixing plate 111 is fixedly connected to the inner side of the side mounting plate 102. A tension spring 112 is fixedly connected to the side of plate 111. A front tension adjusting plate 113 is fixedly connected to the end of tension spring 112 away from the rear spring fixing plate 111. A tension roller shaft 114 is rotatably connected through the inner side of the front tension adjusting plate 113. A friction synchronous belt 115 is sleeved on the circumferential surface of the tension roller shaft 114. A second limiting guide post 127 is fixedly connected to the side of the front tension adjusting plate 113. A motor base 116 is screwed to the side of the side mounting plate 102. A drive motor 117 is fixedly connected to the top of 116. The output shaft of the drive motor 117 is fixedly connected to a drive bevel gear 118. A transmission support plate 119 is fixedly connected to the inner side of the side mounting plate 102. A transmission shaft 120 is rotatably connected through the side of the transmission support plate 119. A synchronous pulley 121 is fixedly connected to the circumferential surface of the transmission shaft 120. A driven bevel gear 122 is fixedly connected to one end of the transmission shaft 120. A rear guide ring 123 is fixedly connected to the inner side of the side mounting plate 102.

[0025] A rear protective cover 128 is fixedly connected to the side of the side mounting plate 102, and a gear protective cover 129 is fixedly connected to the inner side of the side mounting plate 102. The rear spring fixing plate 111, tension spring 112, and front tension adjusting plate 113 are located inside the rear protective cover 128. The driving bevel gear 118 and the driven bevel gear 122 mesh with each other and are located inside the gear protective cover 129. The drive motor 117 drives the driving bevel gear 118 to rotate, and the driving bevel gear 118 drives the driven bevel gear 122 to rotate, thereby realizing the conveying of the cable. The pressure spring 108 and the tension spring 112 apply pressure to the front movable plate 109 and the front tension adjusting plate 113 respectively, so that the front pressure roller shaft 110 and the tension roller shaft 114 can fit tightly against the cable, ensuring the stability and reliability of the conveying. The first limiting guide post 126 and the second limiting guide post 127 limit the movement of the front movable plate 109 and the front tension adjusting plate 113 respectively, preventing them from deviating or falling off.

[0026] The axes of the first drive roller 106, the front pressure roller shaft 110, and the tension roller shaft 114 are parallel to each other, and the friction synchronous belt 115 is connected to each shaft for transmission. The synchronous pulley 121 meshes with the inner side of the friction synchronous belt 115. There are two sets of pressure springs 108, arranged in pairs, and they are symmetrical to each other along the vertical center axis of the side mounting plate 102. There are three sets of tension springs 112 and second limit guide posts 127, which are arranged linearly along the side of the rear spring fixing plate 111. The adaptive cable conveying device 10 can automatically adjust the conveying pressure and tension according to different specifications of cables to ensure that the cable is not excessively squeezed or stretched during the conveying process, effectively protecting the cable from damage. The rear protective cover 128 and the gear protective cover 129 prevent dust and debris from entering the device and extend the service life of the device.

[0027] One end of the adjusting screw 103 abuts against the height slider 104. The circumferential surface of the first limiting guide post 126 penetrates and slides through the side of the rear fixing plate 107. The circumferential surface of the second limiting guide post 127 penetrates and slides through the side of the rear spring fixing plate 111. Two sets of adaptive cable conveying devices 10 are provided and are symmetrical to each other along the vertical central axis of the frame 1. They can simultaneously adaptively convey two cables of different specifications or different directions, improving the efficiency and flexibility of cable laying.

[0028] The handheld guide device 13 includes a guide base 131, which is fixedly connected to the top of the frame 1. A connecting plate 132 is fixedly connected to the top of the guide base 131, and a guide roller 133 is fixedly connected to the top of the connecting plate 132. A rotating chassis 134 is fixedly connected to the top of the frame 1. A rotating shaft 135 is rotatably connected through the top of the rotating chassis 134. A guide chassis 136 is fixedly connected to the end of the rotating shaft 135 away from the rotating chassis 134. A handle 137 is fixedly connected to the side of the guide chassis 136. A rear guide roller 138 is rotatably connected through the top of the guide chassis 136. An angle adjustment plate 139 is fixedly connected to the top of the guide chassis 136. An auxiliary roller 140 is rotatably connected through the inner wall of the angle adjustment plate 139. The handheld guide device 13, through the cooperation of the guide roller 133 and the rear guide roller 138, achieves the initial guidance and support of the cable to meet the needs of different laying angles.

[0029] The auxiliary rollers 140 are arranged in several groups and are linearly arrayed along the inner side of the angle adjustment plate 139. The rear guide rollers 138, the angle adjustment plate 139 and the rotating shaft 135 are arranged in two groups and are symmetrical to each other along the vertical central axis of the guide chassis 136, which can accurately control the direction of the cable in complex environments.

[0030] In use, the operator moves the frame 1 to the starting position of cable laying. Using the flexible steering function of the casters 2, the operator easily adjusts the overall direction of the device to gradually align it with the preset cable laying path. Then, according to the specifications of the cable to be laid, the operator adjusts the adaptive cable conveying device 10 accordingly. For the adaptive cable conveying device 10, the operator first rotates the adjusting screw 103. Since the adjusting screw 103 is threadedly connected to the side mounting plate 102, and one end of it abuts against the height slider 104, as the adjusting screw 103 rotates, the height slider 104 moves up and down on the side of the side mounting plate 102. The sliding height slider 104 moves, causing the adjusting shaft 105 to move synchronously, thereby adjusting the height position of the first transmission roller 106 to adapt to the cable conveying requirements of different diameters. When the cable enters the adaptive cable conveying device 10, the clamping spring 108 takes effect. One end of the clamping spring 108 is fixed to the rear fixed plate 107, and the other end is connected to the front movable plate 109. Under the elastic force of the clamping spring 108, the front movable plate 109 drives the front pressure roller shaft 110 to move towards the cable, so that the front pressure roller shaft 110 is tightly attached to the surface of the cable. The circumferential surface of the first limiting guide post 126 penetrates and slides through the side of the rear fixed plate 107. The front movable plate 109 is limited and guided to prevent it from shifting during movement, ensuring that the front pressure roller shaft 110 always applies pressure to the cable in the correct direction. During cable transport, the tension spring 112 also plays a crucial role. One end of the tension spring 112 is fixed to the rear spring fixing plate 111, and the other end is connected to the front tension adjusting plate 113. It automatically adjusts the position of the front tension adjusting plate 113 according to the cable diameter. When the cable diameter increases, the pressure spring 108 is compressed, and the front pressure roller shaft 110 moves backward. At this time, the pressure spring 108 is compressed, and the friction synchronous belt 11... 5. The tension changes from a tight state to a relatively loose state. However, due to the elastic force of the tension spring 112, the front tension adjusting plate 113 will drive the tension roller shaft 114 to move towards the rear spring fixing plate 111 under the tension of the tension spring 112, so that the friction synchronous belt 115 can regain the appropriate tension, ensuring the stability and continuity of cable transportation. At the same time, the friction synchronous belt 115 has a large contact area with the cable, which can effectively increase the friction and prevent the cable from slipping during transportation. The material of the friction synchronous belt 115 has good wear resistance and flexibility, and it is not easy to wear or break during long-term use.When the cable diameter decreases, the compression spring 108 pushes the front pressure roller shaft 110 forward, ensuring that the front pressure roller shaft 110 always fits tightly against the cable surface. At the same time, the tension spring 112 automatically adjusts the position of the front tension adjusting plate 113 according to the change in cable diameter, causing the tension roller shaft 114 to move accordingly, ensuring that the friction synchronous belt 115 maintains a suitable tension, thereby adapting to the conveying needs of cables of different specifications. During the cable laying process, the handheld guide device 13 plays an important guiding role. The operator holds the handle 137 and can flexibly adjust the direction of the guide chassis 136 by rotating the rotating shaft 135 on the rotating chassis 134, thereby changing the position of the rear guide roller 138 and the angle adjusting plate 139. The cable is first initially guided by the guide roller 133, and then enters between the rear guide rollers 138. The rear guide rollers 138 provide further support and guidance for the cable. Several sets of auxiliary rollers 140, which are rotatably connected through the inner wall of the angle adjustment plate 139, can be flexibly adjusted according to the laying angle of the cable, assisting the cable to pass smoothly through complex environments and ensuring that the cable is accurately laid according to the preset path.

[0031] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, the pressure loss warning device 15 includes a warning support plate 151, which is fixedly connected to the top of the frame 1. A warning slider 152 is slidably connected to the inner side wall of the warning support plate 151. A main hook 153 is fixedly connected to the side of the warning support plate 151. A top rod 154 is fixedly connected to the bottom of the warning slider 152. A mounting groove 155 is provided on the side of the warning support plate 151, and a micro switch 156 is fixedly connected to the bottom of the mounting groove 155. An audible and visual alarm 157 is provided on the side of the warning support plate 151. A tensioning strap 158 is connected to the side of the main hook 153. An auxiliary hook 159 is fixedly connected to the side of the warning slider 152. A contact roller 160 is fixedly connected to the side of the warning slider 152. When all the cables on the winding wheel 4 are laid, the tension of the winding wheel 4 on the cables disappears, thereby triggering the micro switch 156, activating the audible and visual alarm 157 to issue a warning signal, reminding the operator to stop the operation of the device in time and perform cable replacement or other corresponding operations.

[0032] A tensioning strap 158 connects the main hook 153 and the auxiliary hook 159. The trigger end of the micro switch 156 is located on the displacement trajectory of the top rod 154 away from the warning slider 152. The audible and visual alarm 157 simultaneously emits a high-frequency alarm and flashing light to ensure that operators can detect abnormalities in a timely manner even in noisy construction environments.

[0033] The circumferential surface of the top rod 154 penetrates and slides through the bottom inner side of the warning support plate 151. There are two sets of warning support plates 151, warning sliders 152 and tightening straps 158, which are symmetrical about each other along the vertical central axis of the frame 1. The two sets of pressure loss warning devices 15 can immediately trigger the alarm to avoid the interruption of the overall construction due to a single line failure.

[0034] During use, when the cable laying work is proceeding normally, the winding wheel 4 maintains a stable tension on the cable. The warning slider 152 is in its initial position under the tension. At this time, the top rod 154 does not touch the trigger end of the micro switch 156, and the audible and visual alarm 157 is in a silent state. When the cable on the winding wheel 4 gradually decreases until it is completely laid, the tension suddenly disappears. The warning slider 152 slides down rapidly under the elastic force of the tensioning belt 158, driving the top rod 154 to move down synchronously. When the end of the top rod 154 touches the trigger end of the micro switch 156, the micro switch 156 immediately closes, connecting the circuit of the audible and visual alarm 157. The audible and visual alarm 157 simultaneously emits a high-frequency alarm sound and a strong flashing light, forming a dual warning effect of sound and light. When the operator arrives, the power supply of the device can be turned off through the distribution box 5. Then, the cable is replenished or a new cable reel 4 is replaced. During the replenishment or replacement of the cable, the tensioning strap 158 can temporarily fix the remaining cable to prevent the cable from falling. After the cable is processed, the device is restarted. At this time, the cable reel 4 generates a new tension on the cable. Under the action of the tension, the warning slider 152 overcomes the elasticity of the tensioning strap 158 and slides up to the initial position. The top rod 154 moves away from the trigger end of the micro switch 156, and the device returns to the normal cable laying monitoring state.

[0035] A method for laying a cable laying device for power engineering includes the following steps: S1: The operator moves frame 1 to the starting position, adjusts the direction and adjusts the conveying device to accommodate the cable specifications; S2: The conveying device automatically presses and adjusts the tension, and the hand-held guide device 13 guides the cable to be laid according to the preset path; S3: When the cable is used up, an audible and visual alarm is triggered. After the operator replaces the winding reel, the cable laying status is restored.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
