Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary equipment for heavy-duty cables, and in particular to a heavy-duty cable laying device. Background Technology
[0002] Cable laying is a routine operation in electrical work. For laying large-section, long-distance cables, mechanical equipment such as cable laying carts and winches are typically used to pull the cable. Finished cable laying carts usually lay cables horizontally.
[0003] Purchasing such a cable-laying vehicle is costly, has limited versatility, and is subject to stringent on-site conditions, requiring hardened surfaces. Otherwise, the cable laying process may result in tilting and potential safety accidents. Many production workshops or construction sites may not have these conditions. Cable laying operations are typically performed on muddy ground, and such a vehicle, with its small contact area with the ground, may sink into the ground and tilt. This is especially true for heavy cables due to their weight. Utility Model Content
[0004] The purpose of this utility model is to provide a heavy-duty cable laying device in response to the above situation. This laying device is completely self-designed, with a relatively simple structure, but it is very practical.
[0005] The specific solution of this utility model is as follows: a heavy-duty cable laying device, having a chassis, a central column welded at the center of the chassis, a flat bearing mounted on the central column, and four rotating shaft support rods of the same length welded outward in a cross shape on the outer wall of the flat bearing, the four rotating shaft support rods being arranged in the same horizontal plane, and a ball bearing as a rolling wheel installed at the outer end of each rotating shaft support rod, the rolling wheel rolling on the chassis; a lifting ring is also provided at the top end of the central column.
[0006] Furthermore, in this invention, an angle steel reinforcing rib is welded between each pair of adjacent pivot support rods near the outer end, and the upper end face of the angle steel reinforcing rib is flush with the pivot support rod.
[0007] Furthermore, in this invention, each of the aforementioned pivot support rods is provided with a limiting baffle near the inner side of the corresponding ball bearing, and the four limiting baffles are kept at the same position along the length of the pivot support rod.
[0008] Furthermore, the planar bearing described in this invention is movably mounted on the central column.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] See Figures 1-3 This utility model is a heavy-duty cable laying device, comprising a chassis 1. Further, the chassis is disc-shaped and made of 10mm thick steel plate. Further, the disc-shaped steel plate of the chassis has four weight-reducing holes 11. The diameter of the chassis is 1200mm. A central column 8 is welded to the center of the chassis, and a flat bearing 7 is mounted on the central column. Further, the flat bearing is movably mounted on the central column. Four rotating shaft support rods 5 of the same length are welded outwards in a cross shape on the outer wall of the flat bearing. The four rotating shaft support rods are arranged in the same horizontal plane, and a ball bearing is installed at the outer end of each rotating shaft support rod as a rolling wheel 2. The rolling wheel rolls on the chassis. A lifting ring 6 is also provided at the top end of the central column.
[0026] Furthermore, in this utility model, an angle steel reinforcing rib 4 is welded between each pair of adjacent pivot support rods near the outer end, and the upper end face of the angle steel reinforcing rib is flush with the pivot support rod.
[0027] Furthermore, in this utility model, each of the aforementioned rotating shaft support rods is provided with a limiting baffle 3 near the inner side of the corresponding ball bearing, and the four limiting baffles are kept at the same position along the length of the rotating shaft support rod.
[0028] The manufacturing process of this utility model's wire-laying device is as follows: 1. Base plate fabrication: The base plate is made of 10mm steel plate, cut into a circle with a diameter of 1200mm, and four weight-reducing holes are made on it for easy handling and weight reduction. 2. Central column welding: A central column is welded at the center of the circle as an axle. A flat bearing is fitted onto the axle, and a lifting ring is installed above the axle for easy lifting and transport of the tool. 3. Fabrication of the turntable formed by the rotating shaft support rod: Steel bars and angle steel are welded together to form a turntable. Figure 2 As shown, four ball bearings are installed as rolling wheels, which provide stronger radial force.
[0029] See Figure 4 In actual use, the center hole of the cable turntable is first fitted onto the center column, so that the entire turntable is laid flat. Then, the heavy cable can be pulled out for use. When pulling out, the entire cable turntable rotates together with the rolling wheel and the rotating shaft support rod below, and the cable feeding operation is carried out while rotating.
[0030] The chassis of this utility model uses a flat steel plate as the bottom support, so even if the ground is not very flat, it will not affect the laying operation, making it more adaptable to the site.
[0031] This invention revolutionizes traditional cable laying methods. The cable laying device is suitable for use in harsh conditions and is equally convenient for hardened surfaces. It is multi-functional, suitable for both heavy-duty and small cable reel laying. The device is easy to transport and lift; the chassis and other structures can be separated, requiring no mechanical equipment, and can be easily moved by two workers.
[0032] It requires almost no maintenance; just add a little lubricant when using it, and it will work tirelessly.
[0033] The use of this invention saves on the purchase cost of a wire-laying cart. Its application increases the safety and reliability of wire laying, allowing energization to occur before the path is cleared, thus meeting the power requirements of mechanical equipment.
