Description

Technical Field

[0001] The utility model belongs to the technical field of cable installation, and in particular relates to a detachable cable bridge bracket. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In the design and construction stage of industrial equipment such as chemical industry and oil refining, in order to ensure the reliability of the cable tray (trough box) support, a new type of glass fiber reinforced plastic cable tray with publication number: CN207426588U is designed with the tray (trough box) support as a "door" type support. This design style improves the bearing capacity of the support. For example, the F-type support with publication number CN200968445Y is used as a cantilever beam for cable support, and multiple cantilevers can be set to install multiple layers of cables;

[0004] The inventors understand the shortcomings of the prior art: the closed shape of the "door" type bracket means that during the subsequent bridge (trough box) construction, cable laying, inspection and maintenance operations, only the "pushing and pulling" construction method can be adopted in the closed "door" type bracket, which greatly increases the cost. The F-type bracket is used as a cantilever beam to support the cable. Although an opening is set on one side to facilitate the removal of the cable, the cantilever beam has high strength at the root of the support arm and low strength at the end of the support arm, which makes the cable placed on the support arm unevenly stressed and the end of the support arm bends when the cable weight is heavy. Utility Model Content

[0025] The specific implementation of this embodiment is described below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-4 The embodiment of the present application proposes a detachable cable tray bracket, including a fixed column 1, a bracket arm 2 and a movable column 3. A plurality of bracket arms 2 are arranged on one side of the fixed column 1. Specifically, two bracket arms 2 are welded on one side of the fixed column 1. The fixed column 1 and the plurality of bracket arms 2 form an F-shaped structure, which can be used for the installation of multi-layer cables. At the same time, by removing the studs between the bracket arm 2 and the connecting steel plate 4, the movable column 3 is temporarily removed to facilitate the laying and maintenance of the cable. After the movable column 3 is fixed, the fixed column 1, the bracket arm 2 and the movable column 3 form a door-shaped structure, which has the advantages of high bracket bearing capacity and uniform force.

[0027] Reference Figure 3 The movable column 3 is movably connected to the support arm 2 through a connecting steel plate 4. A first L-shaped plate 51 is arranged on the side wall of the movable column 3 and below the connecting steel plate 4. The movable column 3 supports the support arm 2 through the first L-shaped plate 51. A fixed bottom plate 6 is installed at the bottom end of the movable column 3. A second L-shaped plate 52 is arranged between the fixed bottom plate 6 and the movable column 3.

[0028] The support arm 2 is a groove type. The support arm 2 adopts the existing groove steel. The cross-section of the groove steel is a groove type. A screw hole 7 is opened at the bottom of the groove of the support arm 2, and a screw hole 7 is opened on the connecting steel plate 4. The connecting steel plate 4 is arranged on the side wall of the movable column 3. The connecting steel plate 4 is fixed to the support arm 2 by a bolt 8 passing through the screw hole 7. During the specific installation, the prefabricated connecting steel plate 4 is welded to the movable column 3, and then the screw hole 7 of the connecting steel plate 4 is aligned with the screw hole 7 of the support arm 2. Finally, the bolt 8 cooperates with the screw hole 7 on the connecting steel plate 4 and the support arm 2 to connect the movable column 3 to the support arm 2 through the connecting steel plate 4.

[0029] The height of the fixed column 1 is greater than or equal to that of the movable column 3 , and the width of the fixed column 1 is greater than that of the movable column 3 , so as to ensure that the fixed column 1 effectively supports the bracket 2 .

[0030] Reference Figure 2One side of the first L-shaped plate 51 contacts the lower side wall of the support arm 2, and the other side of the first L-shaped plate 51 is connected to the side wall of the movable column 3. Specifically, a prefabricated first L-shaped plate 51 is used, and two first L-shaped plates 51 are selected according to the number of installation layers. First, the side of the first L-shaped plate 51 horizontal to the ground is pressed against the lower surface of the support arm 2, and the side of the first L-shaped plate 51 vertical to the ground is pressed against the side wall of the movable column 3. Then, the side of the first L-shaped plate 51 vertical to the ground is welded to the movable column 3. After welding, the side of the first L-shaped plate 51 horizontal to the ground supports the upper support arm 2.

[0031] The side of the second L-shaped plate 52 that is vertical to the ground is connected to the side wall of the movable column 3 , and the side of the second L-shaped plate 52 that is parallel to the ground is connected to the upper side wall of the fixed bottom plate 6 .

[0032] A screw hole 7 is provided on the side wall of the movable column 3, and a screw hole 7 is provided on a side surface of the second L-shaped plate 52 that is vertical to the ground. The second L-shaped plate 52 is fixed to the movable column 3 by means of a bolt 8 that penetrates the screw hole 7. Specifically, a prefabricated second L-shaped plate 52 can be used, and the lower side surface of the second L-shaped plate 52 can be welded to the bottom plate 6, and then the screw hole 7 of the movable column 3 is aligned with the screw hole 7 provided on one side surface of the second L-shaped plate 52, and then the movable column 3 is fastened to the bottom plate 6 vertically by means of the bolt 8. After fixation, the movable column 3 is stably connected to the bottom plate 6, and after the lower side wall of the bottom plate 6 is fixedly connected to the ground or the high-altitude platform, it is ensured that the movable column 3 will not tip over, thereby ensuring the installation stability of the movable column 3.

[0033] The fixed column 1 is arranged perpendicular to the ground, the movable column 3 is arranged perpendicular to the fixed base plate 6, the bracket 2 is arranged parallel to the ground, and the movable column 3 is arranged perpendicular to the bracket 2. This arrangement makes the cable tray located in a rectangular space, ensuring that there is enough installation space for the cables.

[0034] The first L-shaped plate 51 can be welded to the side wall of the movable column 3 , and the second L-shaped plate 52 can be welded to the upper side wall of the bottom plate 6 .

[0035] The installation steps are:

[0036] First, select two prefabricated support arms 2, two connecting steel plates 4, two first L-shaped plates 51, one fixed bottom plate 6, one fixed column 1 and one second L-shaped plate 52, weld the two support arms 2 to the side wall of the fixed column 1, fix the movable column 3 to the bottom plate 6 through the second L-shaped plate 52, then weld the connecting steel plate 4 to the movable column 3, install the connecting steel plate 4 and the support arm 2 through bolts 8, and then install the second L-shaped plate 52 on the movable column 3 to support the support arm 2.

[0037] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
