Description

TECHNICAL FIELD

[0001] The utility model belongs to cable laying field relates to a device of auxiliary laying cable. BACKGROUND

[0002] Cables are usually stored on cable drums in a coiled form. This coiled state is not only advantageous for storage and transportation, but also effectively protects the cable from external damage. However, when laying the cable for use, releasing the cable from the cable drum can become relatively complex. Although other winding methods exist, they often bring more inconvenience in practical application.

[0003] Currently, conventional cable laying operations require at least two people to cooperate: one person is responsible for pulling the cable for laying, and the other person is responsible for uncoiling the cable from the cable drum one turn at a time to facilitate the former to pull smoothly. However, in this process, the person pulling the cable often needs to wait for the cable to be uncoiled, especially when dealing with larger cable drums, the cable uncoiling staff even needs to move around the cable drum to uncoil the cable, which significantly reduces the cable laying efficiency. SUMMARY

[0004] The present application provides a device for assisting in laying a cable, which can effectively improve the laying efficiency of the cable.

[0005] To achieve the above technical purpose, the technical solution adopted by the present application is a device for assisting in laying a cable, which is installed on a cable drum; comprising

[0006] a vertical guide rod coaxially arranged with the cable drum; a vertical guide rod end head guide ring is arranged at the top end of the vertical guide rod;

[0007] a horizontal guide rod located above the cable drum, installed on the vertical guide rod and perpendicular to the vertical guide rod; a horizontal guide rod end head guide ring is arranged at the top end of the horizontal guide rod;

[0008] a strut rod, one end of which is fixed to the vertical guide rod and the other end of which is fixed to the horizontal guide rod, the vertical guide rod, the horizontal guide rod and the strut rod forming a triangular structure;

[0009] an oblique guide rod installed on the strut rod, the plane in which the oblique guide rod is located being parallel to the plane in which the horizontal guide rod is located; an oblique guide rod end head guide ring is arranged at the top end of the oblique guide rod.

[0010] As an improved technical solution of the present application, the horizontal guide rod is a horizontal telescopic rod.

[0011] As an improved technical solution of the present application, the strut rod and the horizontal guide rod are installed on the vertical guide rod by welding.

[0012] As the improved technical solution of the present application, the cable reel is coaxially installed with the vertical guide rod through a bearing.

[0013] As the improved technical solution of the present application, the length of the vertical guide rod is not less than twice the height of the cable reel.

[0014] Advantages

[0015] The device of the present application can realize the cable laying process without a dedicated person standing by the cable reel to untangle the cable, thereby effectively saving one labor and significantly reducing the labor cost. This automatic feature not only improves the safety of operation, but also greatly improves the efficiency of cable laying, especially when dealing with larger or heavy cable reels. For large projects, this improvement can significantly shorten the construction period and reduce the delay that may be caused by manual operation.

[0016] In addition, the device can also play a key role in preventing winding and guiding when laying cables at high altitudes, ensuring that the cable can smoothly pass through the guide rod and avoiding the cable knotting or blocking problems that may occur in traditional ways. This not only guarantees the integrity and service life of the cable, but also makes high-altitude work more safe and reliable.

DETAILED DESCRIPTION

[0026] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without any creative effort fall within the scope of the present application. Unless otherwise defined, the technical terms or scientific terms used herein should have the usual meanings understood by those of ordinary skill in the art to which the present application belongs.

[0027] The present application promotes the self-help cable reel unwinding by changing the direction of the force through the guidance of the vertical guide rod / horizontal guide rod, etc.

[0028] As shown in Fig. 1, a device for assisting cable laying is installed on a cable reel 9; the device comprises Figure 1 A vertical guide rod 1 is coaxially arranged with the cable reel 9; a vertical guide rod end guide ring 71 is arranged at the top end of the vertical guide rod 1;

[0029] A horizontal guide rod 4 is located above the cable reel 9, is installed on the vertical guide rod 1, and is perpendicular to the vertical guide rod 1; a horizontal guide rod end guide ring is arranged at the top end of the horizontal guide rod 4;

[0030] A strut 2 is fixed at one end to the vertical guide rod 1 and at the other end to the horizontal guide rod 4; the vertical guide rod 1, the horizontal guide rod 4 and the strut 2 form a triangular structure;

[0031] A horizontal telescopic rod 5 is arranged on the horizontal guide rod 4 and is perpendicular to the horizontal guide rod 4; an oblique guide rod 3 is arranged on the horizontal telescopic rod 5 and is perpendicular to the horizontal telescopic rod 5; a bearing 8 is arranged at the top end of the oblique guide rod 3; a cable 10 is wound on the cable reel 9.

[0032] The oblique guide rod 3 is installed on the muscle rod 2, and the plane where the oblique guide rod 3 is located is parallel to the plane where the horizontal guide rod 4 is located; the top end of the oblique guide rod 3 is provided with an oblique guide rod end head guide ring 73. For larger or more winding force cables, the cable needs to be guided upwards, preventing winding and guiding. For the laying of cables on an inclined slope, the cable of the cable reel 9 passes through the oblique guide rod end head guide ring 73, and the oblique guide rod end head guide ring 73 guides the direction of the cable.

[0033] As an improved technical solution of the present application, the horizontal guide rod 4 is a horizontal telescopic rod

[0034] As an improved technical solution of the present application, the muscle rod 2 and the horizontal guide rod 4 are installed on the vertical guide rod by welding.

[0035] As an improved technical solution of the present application, it further comprises a bearing 8, and the cable reel 9 is coaxially installed with the vertical guide rod 1 through the bearing 8. The purpose is to reduce the frictional resistance when the cable reel 9 rotates. In actual application, the cable reel does not rotate, and it is always the device of the present application that rotates, not the cable reel. When used, the device of the present application can be directly placed in the center hole of the cable reel, that is, it can be used and installed at any time, and it can be removed when not in use. Therefore, the device of the present application is convenient.

[0036] As an improved technical solution of the present application, the length of the vertical guide rod 1 is not less than twice the height of the cable reel 9. The purpose is to ensure that the vertical guide rod 1 can extend out of the cable reel 9.

[0037] In specific application, the vertical guide rod is a long square steel, and its size is set to 3 meters. Considering that the cable reel 9 involved in a certain actual application site is about 1.5 meters high, the height of the vertical guide rod is designed to be about twice the height, so as to ensure sufficient operation space.

[0038] The muscle rod 2 and the horizontal guide rod 4 are fixedly connected with the vertical guide rod 1 by welding. The horizontal guide rod 4 adopts a telescopic design, and the transverse length can be freely adjusted according to the needs of different cable reels 9. The telescopic adjustment of the horizontal guide rod 4 is realized by adjusting the positioning hole 6 provided on the horizontal guide rod 4. Since the commonly used vertical height is fixed, the telescopic function is not designed in this direction. Preferably, the vertical guide rod 1 is a vertical telescopic guide rod.

[0039] The vertical guide rod end head guide ring 71, the horizontal guide rod end head guide ring 72, and the oblique guide rod end head guide ring 73 can all use daily gaskets and be fixed on the guide rods by welding.

[0040] The inclined guide rod 3 is detachable, and is installed and detached through the positioning hole 6. This design is suitable for specific working occasions, such as the inclined laying of a long distance cable 10. In daily use, the bearing 8 is usually not required for planar installation. However, for a heavy cable 10, it is necessary to add the bearing 8. According to the principle of physics, when the force increases, the friction also increases accordingly, which makes it difficult for the device to rotate when the cable 10 is heavy. Therefore, when dealing with heavy cables 10, the installation of the bearing 8 should be considered to reduce friction and make the device easier to rotate. The installation of the bearing 8 can be flexibly selected according to the actual cable 10 laying situation.

[0041] In daily use, whether to install the inclined guide rod 3 and the bearing 8 is determined according to specific needs. When in use, the device is directly inserted into the center hole of the cable reel 9.

[0042] The working principle will be described in detail below in the horizontal and vertical directions: when the cable 10 needs to be laid in the horizontal direction, the cable 10 will directly pass through the horizontal guide rod end head guide ring 72, and then the laying personnel will pull the cable 10 forward, at which time the device will rotate in the opposite direction along the direction in which the cable 10 is wound.

[0043] Since the motion path of a point is from the tangent point of the cable reel 9, through a slanting circular motion to the horizontal guide rod end head guide ring 72 of the horizontal guide rod 4. Since this slanting circular motion is three-dimensional, it is difficult to directly analyze the force, so the two-dimensional force analysis of the starting point and the ending point is selected.

[0044] Figure 2 It is shown that after the cable 10 directly passes through the horizontal guide rod end head guide ring 72, the force on any point on the cable 10 wound on the cable reel 9 is shown from the top view (without considering the weight), wherein F represents the direction and size of the force on the point (F must act along the tangent direction of the cable 10 to ensure that the cable 10 can be correctly wound around the circle). F is decomposed into two components: F1 and F2.

[0045] Figure 3 It is shown that from the side view, when the cable 10 passes through the horizontal guide rod end head guide ring 72, the force on any selected point is shown. The cable 10 moves obliquely, so it is subjected to the moment A and the weight moment G. The moment A is decomposed into A1 and A2 two components. Through decomposition Figure 3The moment A in the figure is divided into two components, A1 and A2. According to Newton's third law, the guiding ring will be subjected to two moments A1 and A2 of equal magnitude but opposite directions. Since the counterforce of A2 and all the dead weights are borne by the ground, they are not considered. The counterforce of A1 is always perpendicular to the horizontal guiding rod 4, which makes the guiding rod rotate tangentially around the center of the circle. In the natural state, the cable 10 is usually slack, so Figure 2 The moment shown in the figure is relatively small.

[0046] Therefore, in Figure 4 the final action force downward is entirely borne by the ground, but the horizontal action force is only perpendicular to the horizontal guiding rod and the action force is always perpendicular to the horizontal guiding rod and is along the tangent direction of the cable reel arc, so as to make the horizontal guiding rod make a circular motion around the center of the circle. Due to the influence of the counterforce of A1, the whole device will make a circular motion around the center of the cable reel 9 during the process of dragging the cable 10.

[0047] For the vertical laying cable 10, it is necessary to pass through the guiding ring of the horizontal guiding rod 4 first, and then pass through the vertical guiding rod end guiding ring 71. The horizontal guiding rod 4 is used to untangle the cable 10, and the vertical guiding rod is used to prevent the cable 10 from winding. The specific principle is similar.

[0048] Although the utility model has disclosed as above with preferred embodiments, it is not used to limit the utility model. Those skilled in the art of the utility model can make various changes and decorations without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model is defined by the claims.
