Description

Technical Field

[0001] The utility model belongs to the technical field of installation of a three-phase power line of an overhead crane, and in particular relates to an adjustable fixing buckle for a three-phase power line of an overhead crane. Background Art

[0002] The three-phase power cord used by the overhead crane is flat and is fixed to the steel structure or wall by a buckle during installation. The current buckle is inconvenient to use, the position of the power cord cannot be adjusted, and it cannot be fine-tuned according to the installation environment. For example, if there are steel bars in the wall, if you punch holes on the wall to fix the buckle, you need to avoid punching holes in the steel bars, which will cause the three-phase power cord to twist, which is not only unsightly but also a safety hazard.

[0020] The utility model will now be described in further detail with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, an adjustable fixing buckle for a three-phase power supply slide line of an overhead crane comprises a base 1 and a buckle body 2. The base 1 is provided with a fixing slot 3 and an inner thread hole 4. A fixing bolt 5 is inserted into the fixing slot 3. An adjusting slot 6 is provided on the buckle body 2. A buckle bolt 7 is inserted into the adjusting slot 6. The buckle bolt 7 is threaded into the inner thread hole 4. An upper pressure plate 8 is bolted to the buckle body 2. A lower support plate 9 is welded below the buckle body 2.

[0022] The adjusting slot 6 is located in the middle of the buckle body 2 .

[0023] The inner thread hole 4 is located in the middle of the base 1, and there are two fixing slots 3, which are symmetrically located on the base 1 on both sides of the inner thread hole 4. The inner thread hole 4 is used to bolt the buckle body 2 to the base 1.

[0024] The adjusting slot 6 and the fixing slot 3 are both in the shape of long strips, and the cross sections of the adjusting slot 6 and the fixing slot 3 are both in the shape of T.

[0025] The long strip design is to be able to be adjusted according to the installation conditions, and ultimately ensure that the power cord 12 is not twisted after installation.

[0026] The T-shaped design is to allow the clip bolt 7 and the fixing bolt 5 to be clipped and hidden in the adjustment slot 6 and the fixing slot 3 .

[0027] The clip bolt 7 is a hexagon socket bolt, and the fixing bolt 5 is a hexagon socket bolt or a hexagon socket expansion bolt. The heads of the clip bolt 7 and the fixing bolt 5 are respectively hidden in the T-shaped adjusting slot 6 and the fixing slot 3.

[0028] Meanwhile, the number of the fixing bolts 5 can be determined according to actual conditions, and only one fixing bolt 5 can be inserted into each fixing slot 3, thereby reducing the workload.

[0029] An internal threaded hole 10 is provided on the buckle body 2, and the internal threaded hole 10 is located on the buckle body 2 directly above the adjustment slot 6. A wire pressing bolt 11 that passes through the upper pressure plate 8 is threadedly connected to the internal threaded hole 10, and the upper pressure plate 8 is bolted to the buckle body 2 through the wire pressing bolt 11 and the internal threaded hole 10.

[0030] The lower supporting plate 9 is L-shaped and is located at the bottom end of the buckle body 2 .

[0031] The working principle of the utility model is:

[0032] If it is installed on a steel structure, the base 1 can be directly welded to the steel structure, or a hole can be punched on the steel structure and the base 1 can be bolted to the steel structure through the fixing bolts 5 and nuts. If it is installed on a wall, a hole can be punched on the wall. If a steel bar is encountered during the punching process, the punching position can be changed in the fixing slot 3, and the fixing bolt 5 can be installed in the punched hole. The fixing bolt 5 can be a hexagonal expansion bolt to fix the base 1. The buckle bolt 7 is threaded through the adjustment slot 6 and connected to the inner thread hole 4. The position of the buckle body 2 is adjusted so that it is on the same straight line with other buckle bodies 2, so as to ensure that the power cord 12 will not be twisted after installation. At this time, tighten the buckle bolt 7.

[0033] like Figure 3 As shown, the power cord 12 is clamped on the lower support plate 9, and then the upper pressing plate 8 presses the power cord 12, and the upper pressing plate 8 is pressed on the buckle body 2 through the pressing bolt 11, so as to complete the installation.

[0034] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.

[0035] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
