Description

Technical Field

[0001] This utility model relates to the field of cable crossing technology, and in particular to a cable crossing frame with a stable structure. Background Technology

[0002] Cable crossing frames are temporary facilities that assist in cable laying. They are mainly used in the construction, reconstruction, and maintenance of power transmission lines. When a line needs to cross a highway, railway, or river, cable crossing frames can be used to carry out the construction of the power line without affecting the normal operation of traffic.

[0003] In the prior art, invention patent CN118943942A discloses a cable crossing frame that is easy to assemble and disassemble, comprising: a crossing frame body for raising cables; multiple tensioning devices connected to the crossing frame body; the crossing frame body includes: a supporting vertical frame and a supporting horizontal frame, the supporting vertical frame being vertically arranged, and the supporting horizontal frame being connected to one end of the supporting vertical frame and perpendicular to the supporting vertical frame; a connecting component; a limiting arm; and a base. This invention utilizes the cooperative arrangement of the supporting vertical frame and the supporting horizontal frame. Since both the supporting vertical frame and the supporting horizontal frame are composed of multiple pipe segments connected end to end, assembly and disassembly are convenient and quick. After disassembly, they can be directly bagged and carried by hand. Compared with traditional crossing frames, this significantly improves efficiency, reduces disassembly time, and allows for bagging after disassembly for easy carrying. Furthermore, the tension of the tensioning strap can be adjusted by adjusting the tensioner settings, making the crossing frame more stable and balanced in force, and the adjustment is very convenient.

[0004] The aforementioned patented technology solves the problem of assembling and disassembling cable crossing frames. However, the crossing frames are mainly supported by support columns in the vertical direction, which has limited load-bearing capacity for cables. When bearing a large number of cables, the components are prone to damage due to excessive weight. Utility Model Content

[0006] Furthermore, the spanning frame is composed of two or more sets of the support units connected in sequence.

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.

[0025] Example 1: Refer to Figures 1 to 3 This utility model proposes a structurally stable cable crossing frame. The crossing frame body 1 is used to elevate the cable and includes the crossing frame body 1 and the support crossbeam 4. The crossing frame body 1 is perpendicular to the ground, and the support crossbeam 4 is located at the top of the crossing frame body 1. The crossing frame body 1 includes at least one set of support units. The support unit includes at least one support base 2 and at least three support columns 3. The support base 2 is a regular polygon or a circle and is parallel to the ground. The support columns 3 are evenly distributed along the circumference of the support base 2.

[0026] Specifically, the cross-bracing frame 1 is composed of two or more sets of support units connected sequentially. Adjacent support units are detachable and can be connected by hinges or fasteners. A suitable number of support units are selected based on the actual application scenario to adjust the overall length of the cross-bracing frame 1. In this embodiment, there are five sets of support units. Each support unit includes two equilateral triangular support bases and three support columns 3. The two support bases are connected to the upper and lower ends of the support columns 3, respectively, and are arranged parallel to each other. Mounting holes are provided at the corners of the support bases, allowing the support columns 3 to be connected to each corner of the support base using bolts or hinges. A limiting arm 5 is provided at the end of the support crossbeam 4. The limiting arm 5 extends upwards and limits the cable, preventing excessive displacement of the cable under external force during construction and ensuring the cable remains in a safe and stable position.

[0027] The support frame 4 is provided with a number of insulators 6. The insulators 6 can divide the top surface of the support frame 4 into several sections, so that multiple cables can be insulated from each other when they fall on the support frame 4 at the same time, thus ensuring safety.

[0028] The bottom of the supporting crossbeam 4 is provided with a bearing component, which serves to support the supporting crossbeam 4. The bearing component includes a bearing seat 8 and at least three supporting diagonal rods 9. The bearing seat 8 is arranged parallel to the supporting seat 2 and the two are connected by the supporting diagonal rods 9. The connection between the bearing seat 8 and the supporting diagonal rods 9, as well as the connection between the supporting seat and the supporting diagonal rods 9, can be made by welding or bolting. The connection method of the supporting diagonal rods 9 enhances the stability of the structure to a certain extent. If the main force is the tensile force from a certain direction of the cable, the supporting seat 2 can serve as the main force-bearing end, and the supporting diagonal rods 9 can more effectively disperse the force concentrated in a certain direction, thereby enhancing the ability of the crossbeam 1 to resist deformation on one side.

[0029] The bottom end of the scaffold 1 is provided with a base 7. The base 7 is connected to the scaffold 1 by bolts or pins. The base 7 is provided with a connecting hole. The base 7 is fixed to the ground by ground nails. The connecting hole is adapted to the ground nails. With the help of professional tools, the ground nails are driven into the ground, thereby fixing the scaffold 1 firmly to the ground.

[0030] The working principle of this embodiment is as follows:

[0031] First, five sets of support units are constructed, with two support bases 2 and three support columns 3 forming one set. The two support bases 2 are arranged in parallel, and each support base 2 is connected to the upper and lower ends of the support column 3. The support column 3 is connected to each corner of the support base 2 by bolts. The constructed support units are then fixed to the base 7 by bolts. Adjacent support units are connected by bolts or pins. The load-bearing component is installed on the set of support units furthest from the base 7. The support crossbeam 4 is installed to the load-bearing component, thus completing the construction of the crossing frame. The location where the crossing frame needs to be installed is determined, and the crossing frame is lifted using professional tools and placed in the required location. The base 7 is fixed to the ground with ground nails, and the cable can be placed on the support crossbeam 4. After use, the crossing frame can be laid down first and then disassembled. The disassembled parts are also easy to carry.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
