Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically a new type of ladder cable tray ladder support and a new type of ladder cable tray. Background Technology

[0002] The ladder-type cable tray includes two ladder sides and several ladder supports welded between the two ladder sides. The ladder sides and ladder supports are galvanized before assembly for rust prevention. In the existing technology, when assembling the ladder sides and ladder supports, the two ends of the ladder supports are fixed to the two ladder sides by carbon dioxide welding. However, the carbon dioxide welding process has the following disadvantages: (1) a large bulge is generated at the weld, which affects the appearance; (2) the welding process will damage the zinc layer. In order to prevent rust, it is necessary to use self-spraying paint to touch up the paint after welding. However, the paint will have a color difference with the original zinc layer, which affects the appearance; (3) the welding depends on the experience of the operator. If the experience is insufficient, the verticality between the ladder supports and the ladder sides will not meet the requirements, which will reduce the welding accuracy. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a novel ladder-type cable tray support and a novel ladder-type cable tray, so as to achieve the goals of not damaging the zinc layer during assembly, high assembly precision, and aesthetically pleasing connections.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A novel ladder-type cable tray support includes a cross brace body, with at least one fixing member at each end of the cross brace body that is connected to the ladder side. Each fixing member has at least one protrusion or groove for spot welding.

[0006] As a limitation of this utility model, the fixing member is a sheet structure, the fixing member is perpendicular to the cross brace body, and is integrally set.

[0007] As a further limitation of this utility model, the connection between the fixing member and the cross brace body is transitioned by a rounded corner structure.

[0008] As another limitation of this utility model, each fastener is provided with four protrusions.

[0009] As a limitation of this utility model, each end of the cross brace body has two fixing members, and the two fixing members at either end are arranged opposite to each other.

[0010] As a limitation of this utility model, each end of the cross brace body is provided with three fasteners, and the three fasteners at any end are respectively located on three surfaces of the cross brace body.

[0011] A novel ladder-type cable tray includes two ladder sides and several ladder supports fixed between the ladder sides. The fasteners on the ladder support body are fixedly connected to the ladder sides, and the ladder sides are provided with grooves or protrusions corresponding to the fasteners.

[0012] As a limitation of this utility model, the ladder side is provided with four grooves corresponding to the four protrusions.

[0013] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0014] (1) The present invention provides an extended fixing part on the ladder support body, and the ladder side and the ladder support are fixed by spot welding through the fixing part, which overcomes the disadvantage of carbon dioxide welding fixation in the prior art. The spot welding process does not damage the zinc layer, extends the service life, and does not require subsequent paint touch-up. It will not produce weld protrusions. The overall appearance after assembly is beautiful. When welding, you only need to make the protrusions and grooves correspond and then turn on the power to weld. The operation is simple, there are no technical requirements, there will be no positional deviation, and the welding accuracy is high.

[0015] (2) The fastener of this utility model is integrally formed with the cross brace body by bending, which reduces the production cost and reduces welding marks. At the same time, it is galvanized as a whole, which improves the service life.

[0016] (3) The two fasteners of this utility model can improve the stability of the welding, and the three fasteners further strengthen the fixing strength and extend the service life of the whole.

[0017] In summary, the welding process of this utility model does not damage the zinc layer, the welding quality is high, no weld seams are produced, the overall appearance is beautiful and flawless, the operation is simple, the assembly precision is high, and it is suitable for manufacturing cable trays.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0026] Example 1: Novel Ladder-Type Cable Tray Support

[0027] like Figure 1 As shown, this embodiment includes a ladder support body 1, which is a hollow cuboid. One of its surfaces has an opening 2 extending through the length of the ladder support body 1 and into its hollow inner cavity. This structure is existing technology and will not be described in detail further. Both ends of the ladder support body 1 are fixed with fasteners 3 that connect to the ladder side 5, and each end has at least one fastener 3. Each fastener 3 has at least one protrusion 4 or groove for spot welding. The number of fasteners 3 at both ends can be the same or different; the number of fasteners 3 can be increased according to actual needs.

[0028] In this embodiment, the fixing member 3 is a rectangular sheet structure. Two fixing members 3 are provided at each end of the ladder support body 1. The two fixing members 3 at one end are arranged opposite each other, that is, the fixing members 3 are arranged on both sides of the length direction of the ladder support body 1. The two fixing members 3 at the other end are also arranged opposite each other. Each fixing member 3 is perpendicular to the ladder support body 1 and is integrally formed. That is, the two sides of the end of the ladder support body 1 are bent outward and extended to form the fixing member 3. The side of the fixing member 3 that contacts the ladder side 5 is flush with the end face of the ladder support body 1. The bend is transitioned by a rounded corner structure, so that the connection between the fixing member 3 and the ladder support body 1 is smooth and not easy to break.

[0029] Four protrusions 4 are provided on the fixing parts 3 at both ends of the ladder support body 1 for spot welding. All four protrusions 4 are hemispherical.

[0030] Example 2: Novel Ladder-Type Cable Tray Ladder Support

[0031] like Figure 2 As shown, the structure of this embodiment is basically the same as that of embodiment 1. The difference is that in this embodiment, three fasteners 3 are provided at both ends of the ladder support body 1. The three fasteners 3 at one end are respectively located on three adjacent surfaces at the end of the ladder support body 1. These three surfaces are surfaces without openings 2. The three fasteners 3 at the other end are set in the same way, and are also respectively located on three surfaces at the end of the ladder support body 1.

[0032] Example 3: Novel Ladder-Type Cable Tray

[0033] like Figures 3-5 As shown, this embodiment includes two ladder sides 5 and several novel ladder supports of the ladder type cable tray described in Embodiment 1 fixed between the ladder sides 5. The fixing parts 3 on the ladder support body 1 are spot welded to the ladder sides 5. The ladder sides 5 are provided with grooves 6 corresponding to the four protrusions 4 on the fixing parts 3. When the fixing parts 3 are provided with grooves 6, the ladder sides 5 are provided with protrusions 4.

[0034] When assembling the ladder support and ladder side 5, the fixing parts 3 at both ends of the ladder support body 1 are pressed tightly against the ladder side 5 on both sides, and the four protrusions 4 on the fixing parts 3 are aligned with the four grooves 6 on the ladder side 5. The protrusions 4 and grooves 6 are fixedly connected by spot welding, and the ladder support is fixed to the ladder side 5. Since the spot welding point is located at the contact position of the protrusions 4 and grooves 6, the welding point is hidden between the ladder side 5 and the fixing parts 3, and no welding marks are produced on the appearance. Therefore, the overall appearance is beautiful, the zinc layer is not damaged, and the service life is long.

[0035] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
