Technical Field
[0001] This utility model relates to the field of communication technology for port mobile loading and unloading equipment, and in particular to a cable laying system suitable for mobile devices. Background Technology
[0002] The automation of port mobile equipment is inseparable from cables. For cable laying, the existing technology uses a method of fixing a cable reel to the mobile equipment, releasing the cable as the equipment moves to lay the cable on the running line, and then rewinding the cable on the return trip. With this method, the cable routing is not neat, and the cable is often too tight or too loose during the laying process, resulting in the cable being piled up and messy at the work site, which poses certain safety hazards. At the same time, because the cable is piled up and messy, it is easy for the cable to get tangled together during the cable rewinding process, which can easily cause downtime. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies in port cable laying, which result in messy and stacked cable routing, and to provide a cable laying system suitable for mobile devices.
[0004] The technical solution to the technical problem solved by this utility model is as follows: A cable laying system suitable for mobile devices includes a cable winding and unwinding device, a cable guide device, and a cable tension monitoring device, all mounted on the mobile device. The cable guide device is located below the cable winding and unwinding device. The cable winding and unwinding device is used to store cables and at least release cables. The cable guide device guides the cable released from the cable winding and unwinding device to change direction, so that it falls onto the running line along the running line direction to complete the cable laying. The cable tension monitoring device monitors the tension of the cable located between the cable winding and unwinding device and the cable guide device, and issues a message when the cable is too loose and / or too tight. The cable winding and unwinding device includes a drum and a drum rotation drive device for driving the drum to rotate forward and in reverse. The cable guiding device includes a cable guide frame located below the drum. Multiple guide wheels are arranged on the cable guide frame from top to bottom. The guide wheels guide the cable from vertical to horizontal. The winding and unwinding speed of the cable winding device is matched with the moving speed of the mobile device, so that the cable is laid along the running path of the mobile device. The cable guide frame includes opposing protective plates, with each guide wheel rotatably positioned between the two protective plates. The tangent point between each guide wheel and the cable increases in distance from the center vertical plane from top to bottom. The angle between the cable and the tangent of the lowermost guide wheel is less than or equal to 45 degrees. There are at least two guide wheels, and the lines connecting the tangent points of each guide wheel, guide wheel two, and the cable are arcs. It includes guide wheel group one and guide wheel group two. Guide wheel group one is located above the cable guide frame and includes a pair of parallel guide wheels. Guide wheel group two includes two parallel guide wheels. Guide wheel group two is arranged vertically with guide wheel group one. The wheel axles of guide wheel group one and guide wheel group two are perpendicular to each other. Their planar projections form a "well" shape. The axis of guide wheel group two is parallel to the axis of the guide wheel. After the cable passes through the "well" space formed by guide wheel group one and guide wheel group two, it is tangent to the guide wheel. The cable tension monitoring device includes a tension adjustment device and a cable tension detection alarm device. The tension adjustment device adjusts the cable tension, and the cable tension detection alarm device detects the cable tension. When the cable tension reaches a certain limit, the cable tension detection alarm device sends out a message. The tension adjustment device includes a swing arm, the upper part of which is hinged to a guard plate via a hinge shaft. At least one guide wheel link is fixedly mounted on the swing arm below the hinge shaft, perpendicular to the swing arm. Swing arm guide wheels are rotatably mounted at both ends of the guide wheel link. When the swing arm is in a vertical position, the guide wheels are located outside the arc formed by the tangent points of the cable and each guide wheel. When two or more guide wheel links are provided, the links are arranged vertically, with the distance between the guide wheels on the lower guide wheel link being greater than the distance between the guide wheels on the upper guide wheel link. The guide wheels are located along the centerline of the swing arm. The components are arranged in pairs symmetrically, with the swing arms located between the guide wheels on both sides. When the swing arms are located on the outer side of the guard plate and the swing arm guide wheels are located on the inner side of the guard plate, an arc-shaped groove is provided on the guard plate below the hinge shaft, and the wheel axle of the swing arm guide wheels is located in the arc-shaped groove. The cable tension detection alarm device is a swing arm amplitude detector, which detects the swing amplitude of the swing arms. When the swing amplitude of the swing arms is greater than a set value, an alarm is sent to the control system. The swing arm amplitude alarm detector includes a contact switch and a swing arm trigger element. The swing arm trigger element is located above the hinge shaft and is fixedly connected to the swing arms. The position of the trigger switch corresponds to that of the swing arm trigger element. When the swing arm swings to its maximum position, the cable tension is within the allowable set value range. The edges of each swing arm guide wheel, each guide wheel, and guide wheel two are tangent to the cable, and the line connecting the points of tangency forms an arc. When the swing arm is in a vertical position, the cable loses its supporting force on the swing arm, and the swing arm amplitude detector issues an alarm message. The cable guiding device includes at least three guide wheels, each tangent to the cable. At least the lower guide wheel and the upper guide wheel are not on the same straight line and are far from the vertical plane on the side of the cable, so that the cable contacts the running line at an angle of less than 45 degrees and falls on the running line. The tension adjustment device includes a swing frame. One end of the swing frame is hinged to the lower end of the cable guiding frame, and the other end of the swing frame is a free end. The cable supports the free end of the swing frame, so that the swing frame forms an angle of less than 45 degrees with the running line. A swing frame guide wheel is set at the free end, and the swing frame guide wheel contacts the cable. The cable tension detection alarm device includes a swing frame contact switch and a swing frame trigger element. The swing frame contact switch is located at the lower end of the cable guiding frame, and the swing frame contact switch is located at the top end of the swing frame and at the two ends of the swing frame hinge shaft, respectively. When the lifting angle of the free end of the swing frame exceeds a certain limit, the swing frame contact switch and the swing frame trigger element contact each other to issue an alarm message. It also includes a cable laying platform and a mobile equipment guide rail. The cable laying platform is located below the mobile equipment. The cable laying platform includes a platform and a support frame. The platform is fixed and supported by the support frame. The length direction of the platform is parallel to the mobile equipment guide rail. Sides are provided on both sides of the platform along the length direction of the platform. The sides are segmented and adjacent sides are fixedly connected by connecting plates. The upper and lower ends of the side are arc-shaped to form arc-shaped rolled edges. Correspondingly, the connecting plates are U-shaped. The arc-shaped rolled edges at the upper and lower ends of the side are covered by the two arc-shaped arms of the U-shaped connecting plates and fixedly connected by bolts. A cable routing device is installed between the cable guide frame and the drum. The cable passes through the cable routing device and enters the "well" shaped space formed by the first guide wheel group and the second guide wheel group.
[0005] The advantages and beneficial effects of this utility model are as follows: This utility model discloses a cable laying system suitable for mobile devices. The cable is stored on the mobile device via a cable winding and unwinding device, which then carries the cable. The cable is released by the winding and unwinding device and guided laterally by a cable guide device, aligning the cable's direction with the mobile device's running direction. The cable is laid along the same running direction on the designated path. A cable tension monitoring device monitors the cable tension before laying, issuing warnings when the cable is too loose or too tight. The mobile device and the cable winding and unwinding device can then stop for adjustment and maintenance. This prevents cable stacking and tangling due to excessive looseness and cable breakage or excessive wear on the cable guide device due to excessive tightness.
[0006] Furthermore, guided by the guide wheels, the cable turns from vertical to horizontal, allowing it to fall more neatly onto the ground or support platform. This prevents the cable from swinging excessively during installation. With the help of the mobile equipment, the cable can be laid relatively smoothly on the ground or other platform surfaces in the set direction, preventing messy cables at the work site and reducing or preventing safety accidents.

Detailed Implementation
[0009] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.
[0010] like Figure 1-11As shown in the figure, the cable laying system for mobile devices according to the present invention includes a cable winding and unwinding device 100, a mobile device 400, a cable guide device 300, and a cable tension monitoring device 700. The cable winding and unwinding device 100, the cable guide device 300, and the cable tension monitoring device are all located on the mobile device 400. The cable guide device is located below the cable winding and unwinding device. After the cable released from the cable winding and unwinding device enters the cable guide device, it changes direction under the guidance of the guide wheel, changing from vertical to horizontal, so that the direction of the cable after exiting the cable guide device is close to the direction of the running line. The closer the two are to being parallel, the better. When the mobile device moves back and forth between two points, the cable winding and unwinding device releases and rewinds the cable at a certain speed. When only wiring is done through the mobile device, the cable winding and unwinding device does not need to rewind the cable. The cable winding and unwinding device can adopt existing technologies such as electric drum winches and cable reel devices. Regardless of the structure, it includes a drum for storing the cable and a drum drive device for driving the drum to rotate. Taking a cable reel device as an example, it typically includes a cable reel and a reel rotation drive. The cable is wound around the outside of the reel. In port operations, the mobile equipment 400 not only carries the cable winding and unwinding device and drives it to move along the designated operating line, but it is also the working equipment. The laid cable provides power and transmits communication signals to the mobile equipment. The cable is guided by the cable guide device to fall inclinedly down the operating line from a position above it. When the cable meets the operating line, the angle between the cable and the operating line should preferably be less than or equal to 45 degrees. This ensures that the cable falls smoothly and prevents large swings in the air during the laying process. Driven by the mobile equipment, the cable 1 can be laid smoothly on the ground or other platform surface along the designated direction. In one embodiment, the cable guiding device includes a cable guide frame 301, which includes two opposing guard plates 3011. Multiple guide wheels 304 are rotatably arranged between the two guard plates. The two ends of each guide wheel are rotatably connected to the corresponding guard plate. The axles of each guide wheel are parallel, and the tangent points of each guide wheel and the cable are sequentially moved away from the central vertical section, ensuring that the angle between the cable and the horizontal plane is less than or equal to 45 degrees when the cable leaves the lowest guide wheel. Above the guide wheels, at the top of the guard plates, is a second guide wheel group 303, composed of two parallel guide wheels 3031 of equal height. The axles of the second guide wheels are parallel to the axles of the guide wheels. Above the top of the guard plates, is a first guide wheel group 302, composed of two parallel guide wheels 3021. The axles of the first and second guide wheels are perpendicular, and the planar projections of the first and second guide wheel groups form a "well" structure. After hanging down from the drum, the cable freely enters the grid space formed by guide roller group one and guide roller group two. That is, the cable guide frame is located diagonally below the drum.The mobile device 400 includes a vehicle body, a cable guide frame, and a cable winding / unwinding device, all fixedly mounted on the vehicle body. The cable winding / unwinding device 100 is located above the cable guide frame. The second set of guide wheels is parallel to the axis of the drum, while the first set of guide wheels is positioned below the side surface of the drum, allowing the cable to enter the first set of guide wheels almost vertically. After passing through the first set of guide wheels, the lower end of the cable passes through the second set of guide wheels and then winds around the side surfaces of each guide wheel, exiting in a basically straight state. The two ends of the cable are connected to a ground-side adapter and an electronic control device on the mobile device side, respectively. In this way, the equipment on the mobile device can connect to the ground-side adapter via cable, and the adapter receives power and control signals from the ground-side adapter. During operation, both ends of the cable are pre-connected to the ground-side adapter, and the other end is connected to the electrical control device on the mobile device. As the mobile device moves from the dock side to the ship side, it travels along a designated route at a certain speed. The cable unwinding device unwinds the cable at a certain speed. Because the planar projections of guide wheel group one and guide wheel group two form a "well" shape, the cable is limited, ensuring that the cable released from the drum is released from a relatively fixed position. This ensures that the cable unwinding speed matches the moving speed of the mobile device. After the cable is released, it falls onto the support surface and is laid along the mobile device's trajectory, preventing a messy layout. For example, when the mobile device travels in a straight line, the cable is laid in a straight line, preventing cable tangling. Ideally, the two guide wheels are tangentially positioned. In a preferred embodiment, there are two or more guide wheels, and the lines connecting the tangent points of each guide wheel, guide wheel two, and the cable form an arc. This disperses the pressure of the cable on the guide wheels and guide wheels two, and also extends the cable's lifespan. Ideally, the guide radii of all guide wheels and guide wheel two should be equal, and their centers should form an arc. The guide radius of guide wheels and guide wheel two refers to the radius of the point where the guide wheel or guide wheel two is tangent to the cable.
[0011] The cable guide can also be made into a swingable structure, so that when the cable is tight, the cable guide can swing upward to relieve the tension of the cable. Of course, a swing frame can also be set between the guide wheel and the cable guide, with the swing frame hinged to the cable guide and the guide wheel rotatably connected to the swing frame, which can also play the role of adjusting the tension of the cable.
[0012] Ideally, a cable routing device 200 should be installed between the cable guide frame and the drum. The cable passes through the cable routing device and enters between the two guide rollers of the guide roller group. In this way, when the cable is wound up, the cable can be neatly arranged on the surface of the drum, reducing the range of tension changes during cable unwinding and facilitating tension adjustment.
[0013] The cable tension monitoring device can adjust and monitor the cable tension. When the cable tension exceeds the set limit, the cable tension monitoring device sends a message to prevent the cable from getting stuck and tangled during winding and unwinding, making the cable routing smoother. The cable tension monitoring device includes a cable tension adjustment device and a cable tension detection alarm device. The cable tension adjustment device includes a swing arm 701, a swing arm guide wheel 702, and a guide wheel connecting rod 704. The upper end of the swing arm is hinged to a side guard plate via a hinge shaft. When the swing arm and the swing arm guide wheel are located on both sides of the guard plate, an arc groove 707 is provided on the guard plate below the hinge shaft. At least one guide wheel connecting rod 701 is provided on the swing arm below the hinge shaft. The guide wheel connecting rod is fixedly connected to the swing arm through its middle part. At least one swing arm guide wheel 702 is rotatably provided at both ends of the guide wheel connecting rod 701. Preferably, the center line connecting the two swing arm guide wheels at both ends of the guide wheel connecting rod is perpendicular to the vertical center line of the swing arm. When the arc groove is provided, the axles of both swing arm guide wheels are located in the arc groove. The center of the swing arm guide wheel is located outside the line connecting the tangent point of each guide wheel and the cable. The cable passes between the two swing arm guide wheels. When the cable is laid down quickly, meaning it's relatively loose, the swing arm guide wheel is far from the arc formed by the guide wheels, and the swing angle of the swing arm is small. When the cable is laid down slowly, the swing arm passively swings towards the arc formed by the guide wheels to reduce the overall cable tension, thereby adjusting the cable tension. When two or more arc-shaped grooves are set, the grooves are arranged vertically, and the number of guide wheel connecting rods corresponds to the number of arc-shaped grooves. The distance between the guide wheels on the lower guide wheel connecting rod is greater than the distance between the guide wheels on the upper guide wheel connecting rod. The cable tension detection and alarm device includes a swing arm amplitude detector 706. This detector detects the swing amplitude of the swing arm under cable drive. When the swing amplitude exceeds a set value, the detector sends an alarm signal to the control system. The swing arm amplitude detector can be a contact switch or an angular displacement sensor, preferably a contact switch. A swing arm triggering element 705 is located at one end of the swing arm above the hinge shaft, capable of triggering the contact switch. The triggering element 705 corresponds to the position of the trigger switch. When the swing arm rotates to a certain angle, the triggering element contacts the trigger switch, causing it to send an alarm signal. The connecting hole on the connecting plate, which enables the swing arm guide wheel to rotate with the swing arm, is an oblong hole. The length of the oblong hole is aligned with the orientation of the two swing arm guide wheels. This allows adjustment of the distance between the two swing arm guide wheels and the distance of the arc formed by them, thereby adjusting the cable tension. Ideally, the guide wheels are arranged in pairs, symmetrically positioned relative to the vertical center line of the swing arm in its natural vertical state. In this way, when the guide wheel on one side is worn, the cable guide frame can be rotated 180 degrees and continued to be used, saving maintenance and replacement time.In a preferred embodiment, when the swing arm swings to its maximum position, the cable tension is within an allowable set value range, and the edges of each swing arm guide wheel, each guide wheel, and guide wheel two are tangent to the cable, with the line connecting the points of tangency forming an arc. This structure can maintain the stability of the cable angle, further reduce the pressure on the cable and each swing arm guide wheel, each guide wheel, and guide wheel two, and extend their service life.
[0014] like Figure 11 As shown, in another embodiment, the cable guiding device includes a cable guide frame and at least three guide wheels. The upper end of the cable guide frame is fixedly connected to the frame of the mobile device, and the lower end is close to the running line. The guide wheels are arranged from top to bottom along the cable guide frame and are rotatably connected to the cable guide frame. At least the guide wheel located at the bottom is not on the same straight line as the guide wheel located at the top, and is away from the vertical plane located on the cable side. In this way, the cable can be guided to be laid on the running line at a very small angle with a very simple structure. The cable tension adjustment device includes a swing frame 708. One end of the swing frame is hinged to the bottom of the cable guide frame, and the other end is a free end. The cable passes under the swing frame, and the swing frame is supported by the cable, so that the swing frame tilts from top to bottom from the cable side towards the cable laying direction. Preferably, the free end of the swing frame is provided with a swing frame guide wheel 709, and the swing frame makes rotatable contact with the cable through the swing frame guide wheel. The cable guide device and cable tension monitoring device with this structure utilize a hinged connection between the swing frame and the cable guide frame. The cable passes underneath the swing frame, thus partially supporting its weight. When the cable is tight, it inevitably lifts the free end of the swing frame; when loose, it lowers. This allows for automatic adjustment of the cable tension. The cable tension detection and alarm device includes a swing frame contact switch and a swing frame trigger element. The contact switch is located on the cable guide frame, and the trigger element is located on the top of the swing frame, on either side of the hinge shaft. When the swing amplitude exceeds a certain limit, the trigger element contacts the contact switch, generating an alarm signal.
[0015] The cable laying platform 500 and the mobile equipment guide rail 600 are designed to prevent cables from being crushed or trampled. The cable laying platform includes a frame, which comprises a support frame 501 and a platform 502. The platform 502 is fixedly mounted on the upper end of the support frame 501. The platform can be a flat structure or it can be composed of multiple horizontal beams arranged side by side, with the tops of each beam forming the platform. Side rails 503 are provided on both sides of the platform along its length. These side rails and the platform form a U-shaped channel. The purpose of the side rails is to protect the cable platform from deformation when subjected to external impact. The lower end of the side rail is fixedly connected to the platform, while the upper end extends above the top of the platform. The platform is fixedly connected to the top of the support frame via the side rails. The side panel is segmented, with each segment fixedly connected by a connecting plate 504. Ideally, the connecting plate is U-shaped, and it features curved rolled edges 505. The upper and lower U-shaped edges of the side panel fit snugly against the curved rolled edges at both ends. These curved rolled edges are covered by the two curved arms of the U-shaped connecting plate and secured with bolts. This segmented structure allows the side panel to adapt to varying terrain, enabling the platform to follow the contours of the ground, reducing the need for perfect ground level and simplifying installation. The curved edges at both ends match the curvature of the U-shaped edges of the connecting plate, increasing its impact resistance without increasing the overall thickness and providing better cable protection.
[0016] The mobile device guide rail is located on the side of the cable laying platform and extends along with the platform. Mobile device guide rails are installed on both sides of the cable laying platform, and the mobile device is positioned above the top of the platform. This allows cables to be laid from above onto the cable laying platform. The mobile device is equipped with moving wheels 401, which are rotatably connected to the mobile device guide rails. The mobile device straddles the cable laying platform. The mobile device guide rails allow the mobile device to move along them, improving the repeatability of the movement trajectory and reducing the difficulty of adjusting cable tension.
[0017] In this invention, the mobile equipment can be a rail-mounted gantry crane, a quay crane, or a mobile belt conveyor.
