Description

Technical Field

[0001] This invention relates to the field of power construction, specifically to a cable transport tool for power construction. Background Technology

[0002] Rolled cables need to be handled and moved during the installation process; Traditional cable conveying devices require the cable to pass through the center of the cable reel using a through-shaft, and then be raised and lowered by adjusting devices at both ends to lift the cable reel off the ground. The cable is then released by rotating along the through-shaft. In this technical solution, the center of gravity of the cable reel is located at the through-shaft, which is at least at the radius of the cable reel. Because of the high center of gravity, the reel may tip over during movement due to bumps.

[0003] The existing solution involves placing the cable reel flat and installing a rotating mechanism below it for rotation, as illustrated in patent CN217229731U, which describes a horizontal cable reel and a cable feeding device containing it, belonging to the technical field of cable feeding equipment. The horizontal cable reel includes: a fixed support plate; a rotating support assembly mounted on the upper side of the fixed support plate; a rotating plate placed on the upper side of the rotating support assembly, with a circular protrusion on its lower side; and a rocking brake mechanism, comprising a fixed connecting part, a rocking movable part, and a brake part. The fixed connecting part is connected to the fixed support plate, the rocking movable part is movably connected to the fixed connecting part, and the brake part is connected to the fixed connecting part and extends towards the circular protrusion. When the rocking movable part is activated, the brake part can move closer to the circular protrusion and abut against its outer wall, and move away from the circular protrusion and release its abutment. This technical solution discloses a horizontal cable feeding technique.

[0004] The existing national standard GB 50168 stipulates that cable reels must be placed upright during transportation, long-term storage, and routine loading and unloading, and are strictly prohibited from being laid flat to avoid cable deformation, reel damage, and safety accidents. Therefore, this technical solution is not applicable to technical solutions for transporting cables with a lower center of gravity. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This cable transport fixture for power construction includes a cable reel for winding cables placed on top of a transport vehicle. The transport vehicle is equipped with a rotating part that contacts the cable reel from the bottom. The cable reel rotates relative to the rotating part. This technical solution, by placing the cable reel on the rotating part and restricting its position, and by limiting the contact between the rotating part and the cable reel to the bottom, allows the cable reel to be placed on the rotating part. The cable reel is then unloaded by rotating. This design lowers the center of gravity of the cable reel below its central axis during the unloading process, thus preventing the cable reel from tipping over due to an excessively high center of gravity.

[0017] 2. This cable transport fixture for power construction has a fixed ring connected to a traction rope, a rotating part that is a smooth plane with the same diameter as the fixed ring, and a plug shaft that limits the rotation range of the fixed ring. The upper end face of the transport vehicle is provided with a plug hole to accommodate the plug shaft. The plug hole is located at the center of the fixed ring and / or multiple plug holes are located on the outer ring of the fixed ring. With this configuration, the cable reel laid flat can be loaded onto the vehicle by using traction and lifting to move the vehicle. After loading, it does not need to be disassembled. The cable reel can be rotated and released by limiting its movement range simply by using the plug shaft. This configuration enables fast loading and fast cable release.

[0018] 3. The cable transport fixture for power construction includes a rotating part with a groove set in the plane of the transport vehicle. A support half-ring concentric with the cable reel is slidably connected inside the groove. A set of rolling elements along the edge of the support half-ring is set inside the support half-ring. A notch tangent to the plane of the transport vehicle is set at the tail end of the support half-ring. A limit connection is set between the rotating part and the transport vehicle through a plug-in support block. This technical solution enables rapid installation.

A sleeve is rotatably connected to the outer surface of the through-shaft. Extension ropes are connected to both ends of the through-shaft. The two extension ropes are fixedly connected on the side away from the through-shaft by a winding rope. With this arrangement, the sleeve rotates relative to the through-shaft. The two sides of the extension rope are fixedly connected by a fixed shaft. The winding rope is connected at the halfway point of the fixed shaft.

[0020] 5. The cable transport tool for power construction has multiple protrusions on the side of the cable reel that contacts the ground. The length of each protrusion is less than the radius of the cable reel and they are evenly spaced.

[0026] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0027] like Figure 1-10 As shown, Example 1: A cable transportation tool for power construction includes a transfer vehicle 1 for transferring and laying cables. The transfer vehicle 1 is a commonly used device in the prior art. Its bottom is equipped with a unit for walking. Common types include tracked and wheeled types. The transfer vehicle 1 is equipped with a braking device for the cable reel 2 during the cable laying process in accordance with national standards, as well as other auxiliary cable laying devices. This part is not related to the improvement, so it will not be described in detail.

[0028] A cable reel 2 for winding cables is placed on top of the transfer vehicle 1. The transfer vehicle 1 is equipped with a rotating part 3. The rotating part 3 contacts the cable reel 2 from the bottom. The cable reel 2 rotates relative to the rotating part 3. This technical solution, by placing the cable reel 2 on the rotating part 3 and restricting the position of the cable reel 2 by the rotating part 3, and by limiting the contact between the rotating part 3 and the cable reel 2 from below, allows the cable reel 2 to be placed on the rotating part 3. The cable is unloaded by rotating the cable reel 2. This setting can lower the center of gravity of the cable reel 2 to below its central axis during the unloading process, thereby preventing the cable reel 2 from tipping over due to an excessively high center of gravity.

[0029] The front end of the transfer vehicle 1 is equipped with a traction mechanism 4, which is equipped with a traction rope 5. The traction rope 5 is connected to the cable reel 2. The rear end of the transfer vehicle 1 is movably connected to an inclined plate 6. The inclined plate 6 and the upper surface of the transfer vehicle 1 are equipped with guide rails 9 to guide the cable reel 2 to the rotating part 3. This part serves as an auxiliary device for moving the cable reel 2 onto the transfer vehicle 1. By connecting the traction rope 5 to the cable reel 2 and setting the inclined plate 6, the cable reel 2 can roll onto the transfer vehicle 1. The traction mechanism 4 drives the traction rope 5 to rewind, thereby pulling the cable reel 2 onto the transfer vehicle 1.

[0030] When the axis of the cable reel 2 is parallel to the ground, the rotating part 3 includes a groove 301 provided on the plane of the transfer vehicle 1. A support half-ring 302 concentric with the cable reel 2 is slidably connected inside the groove 301. A set of rolling elements 303 along the edge of the support half-ring 302 is provided inside the support half-ring 302. A notch tangent to the plane of the transfer vehicle 1 is provided at the tail end of the support half-ring 302. A limiting connection is provided between the rotating part 3 and the transfer vehicle 1 through a plug-in support block 304. Specifically, the plane of the transfer vehicle 1 is modified first to create a groove 301 that can engage the support half ring 302. The groove 301 includes a protrusion that restricts the vertical pull-out of the support half ring 302. Then, the support half ring 302 is customized. The cross-sectional shape of the support half ring 302 is adapted to the groove 301 and is engaged inside the groove 301 by rotation. The rolling element 303 provided on the contact surface between the support half ring 302 and the cable reel 2 can be a roller, and the end that first contacts the cable reel 2 is beveled. After installation, the cable reel 2 is brought into contact with the support half-ring 302. First, the cable reel 2 is rolled onto the transfer vehicle 1, keeping the support half-ring 302 and its rotating oblique end tangent to the plane of the transfer vehicle 1. The cable reel 2 is rolled again until its axis coincides with the axis of the groove 301. At this point, the support half-ring 302 is rotated, with its outer side sliding relative to the transfer vehicle 1 and its inner side sliding relative to the cable reel 2. After sliding until it covers the cable reel 2, the rotation is stopped, and the support half-ring 302 is fixed by inserting the support block 304 into it and the transfer vehicle 1. Under these conditions, the cable reel 2 can rotate relative to the support half-ring 302, thus enabling cable feeding. It should be noted that the cross-sectional shape of the supporting semi-ring 302 may not be the same as that of the groove 301, and may only form a semi-enclosure on one side of the cable reel 2.

[0031] An extension protrusion 305 is fixedly installed on the upper surface of the transfer vehicle 1. The groove 301 extends into the interior of the extension protrusion 305. The central angle formed by the two ends of the groove 301 and the axis of the rotating part 3 is greater than 60 degrees. The function of the extension protrusion 305 is to extend the groove 301, increase the contact area between the support semi-ring 302 and the transfer vehicle 1, and avoid deformation and detachment due to insufficient contact area.

[0032] The traction rope 5 includes a through-shaft 501 for passing through the axis of the cable reel 2. A sleeve 502 is rotatably connected to the outer surface of the through-shaft 501. Extension ropes 503 are respectively connected to both ends of the through-shaft 501. The two extension ropes 503 are fixedly connected to the side away from the through-shaft 501 by a winding rope 504. With this arrangement, the sleeve 502 rotates relative to the through-shaft 501, thereby enabling the cable reel 2 to rotate.

[0033] The two sides of the extension rope 503 are fixedly connected by the fixed shaft 505, and the winding rope 504 is connected to the two-part point of the fixed shaft 505. The other end of the extension rope 503 is fixed by the fixed shaft 505 to avoid the problem of friction between the extension rope 503 and the cable reel 2 during the process of the extension rope 503 being gathered from both sides to the middle.

[0034] In Example 2, when the axis of the cable reel 2 is perpendicular to the ground, communication cables for communication need to be laid at the same time as the cable is laid. Communication cables are not restricted by national standards and can be square. However, it is difficult to move the square cable reel 2 on the transport vehicle 1 outdoors. Even if an inclined plate 6 is set up, it is still difficult to slide and drag the cable reel 2 onto the vehicle. At the same time, it is also difficult to raise and install it on the horizontal cable laying reel unless a crane or other mechanical auxiliary device is used. However, it is difficult for large machinery to follow the working environment for hoisting when working outdoors.

[0035] Multiple protrusions 201 are provided on the side of the cable reel 2 that is in contact with the ground. The length of each protrusion 201 is less than the radius of the cable reel 2 and they are evenly distributed. The cable reel 2 is supported by the protrusions 201, and the gaps formed between the protrusions 201 provide operating space.

[0036] A lifting and moving unit 7 for lifting the cable reel 2 is inserted in the gap formed by adjacent protrusions 201. The lifting and moving unit 7 includes a lifting part 701 that engages with the protrusions 201 on both sides, and a moving part 702 located below the lifting part 701. An active telescopic part 703 that restricts vertical movement is provided between the moving part 702 and the lifting part 701. The moving part 702 extends at least to the outside of the moving part 702. The moving part 702 is provided with a engaging part 704 that connects to the fixing ring 8. The lifting and moving unit 7 is inserted into the gap formed by the protrusion 201. The edge of the lifting part 701 is engaged with the protrusion 201 to restrict its swing. After multiple lifting and moving units 7 are inserted into the designated positions, the active telescopic part 703 is operated as a whole to raise the active telescopic part 703 and lift the cable reel 2 away from the ground. The active telescopic part 703 can be a pneumatic telescopic component or a hydraulic telescopic component, but the control end needs to work together. The moving part 702 can be regarded as a chassis, and a universal rolling mechanism is installed under the chassis for movement.

[0037] Multiple lifting and moving units 7 are fixedly connected by a fixing ring 8 formed by vertically inserting and splicing multiple semi-rings. The fixing ring 8 is connected to the snap-fit ​​part 704, so that the multiple lifting and moving units 7 form a whole and can face the same direction during movement.

[0038] The fixed ring 8 is connected to the traction rope 5. The rotating part 3 is a smooth plane with the same diameter as the fixed ring 8, and a plug shaft 306 limits the rotation range of the fixed ring 8. The upper end face of the transfer car 1 is provided with a plug hole 307 for accommodating the plug shaft 306. The plug hole 307 is located at the center of the fixed ring 8 and / or multiple holes are located on the outer ring of the fixed ring 8. With this arrangement, the cable reel 2 can be loaded onto the car by using traction and lifting the moving unit 7. After loading, it does not need to be disassembled. The cable reel 2 can be rotated and unloaded by limiting the movement range of the plug shaft 306. With this arrangement, the effects of quick loading and quick unloading can be achieved.

[0039] The inner side of the moving part 702 protrudes from the supporting part 701. A bearing groove 705 is provided on the upper surface of the moving part 702. A moving ring 706 is slidably engaged on the side of the cable reel 2 that contacts the ground. In the initial state, the moving ring 706 is restricted from moving downward by friction with the sliding groove that fixes the cable reel 2. Only under the action of external force does the moving ring 706 move downward to form a protrusion. Under the action of external force, the moving ring 706 moves downward and engages in the bearing groove 705. This technical solution is a reinforcement of the fixed ring 8 for fixing the moving supporting unit 7. By setting the moving ring 706 from the inner ring to engage the supporting unit 7, the connection of multiple supporting units 7 can be ensured to be stable.

[0040] The cable reel 2 has reinforcing ribs 202 on both sides. This design allows the cable reel 2 to be integrally formed. However, since the protrusion 201 protrudes from the surface of the cable reel 2, the connection part is reinforced by the reinforcing ribs 202. The cable reel 2 has a bushing part 203 coaxial with the shaft. The bushing part 203 facilitates the placement of the central shaft and disassembly and transportation. The bushing part 203 and the outer ring are connected by a through hole 204 parallel to the axis and penetrating the cable reel 2. The through hole 204 can reduce the overall weight. At the same time, the through hole 204 can be used to push the moving ring 706 downward and engage it in the bearing groove 705.
