[0002] With the rapid development of my country's economy, especially the rapid rise of the construction industry, the use of cable trays has greatly increased. At present, cable trays are divided into trough-type, tray-type, ladder-type, grid-type and other structures, and are composed of brackets, brackets, hangers and installation accessories. The bridge in the building can be erected independently or attached to various buildings (structures) and pipe gallery brackets. It should reflect the characteristics of simple structure, beautiful shape, flexible configuration and convenient maintenance. All parts must be galvanized and installed in the open-air bridge outside the building. The bridge bracket on the market is composed of suspension hoisting, mounting brackets, brackets and mounting plates. At this time, the entire equipment is installed by suspension hoisting. After installation, the bracket, mounting bracket and mounting plate are used to lay the bridge. Because different brackets are used for different bridge supports, different brackets need to be adapted. The area of ​​the bracket cannot be adjusted according to the area of ​​the bridge, which reduces the practicality of the bracket and increases the cost of bridge installation. Utility Model Content

When the fixing component 4 is set, the pre-buried lines required for the bridge frame installation can be placed on the transverse connecting rod 2 and the storage plate 5 along the lead hole 3, which can effectively avoid the entanglement of the lines. At the same time, when in use, the fixed installation plate 401 and the plug plate 402 are fixedly installed. At this time, the plug plate 402 is inserted into the locking frame 403, so that when in use, the fixed installation plate 401 can increase the thickness of the supporting frame 1 to avoid deformation caused by collision during installation.

[0023] See also Figure 2 , a support base 6 is installed at the lower end of the inner part of the support bracket 1, and an extension component 7 for adjusting the use area is arranged on the left and right sides of the upper end of the support base 6, and the extension component 7 includes a two-way driving machine 701, a hollow frame 702, a positive and negative screw rod 703, a moving block 704, a connecting rod 705, an electric push plate 706 and an extension plate 707, a hollow frame 702 is arranged outside the two-way driving machine 701, and a positive and negative screw rod 703 is installed inside the hollow frame 702, and a moving block 704 is slidably connected to the surface of the positive and negative screw rod 703, and a connecting rod 705 is installed at the lower end of the moving block 704, and an electric push plate 706 is installed below the connecting rod 705 6, and an extension plate 707 is installed at the end of the electric push plate 706. The setting of the extension component 7 causes the two-way driving machine 701 to start working through the control switch when the bridge frame is installed. When the two-way driving machine 701 is working, the forward and reverse screw rods 703 rotate clockwise inside the hollow frame 702, so that during the rotation process, the moving block 704 drives the connecting rod 705 to slide along the surface of the forward and reverse screw rods 703. Then, during the sliding process, the electric push plate 706 pushes the extension plate 707 from the inside to the outside along the inside of the support frame 1, thereby expanding the use area of ​​the support frame 1, making it suitable for supporting the installation of bridge frames of different areas, and improving the practicality of the device.

[0024] See also Figure 3, a mounting back plate 8 is installed at the rear of the support bracket 1, and a connecting frame 9 is arranged on the left and right sides of the surface of the mounting back plate 8, a mounting assembly 10 for adjusting the mounting height is arranged inside the connecting frame 9, and the mounting assembly 10 includes a motor 1001, a threaded rod 1002 and a nut seat 1003, the output end of the motor 1001 is connected to the threaded rod 1002, and the surface of the threaded rod 1002 is slidably connected to the nut seat 1003, the mounting assembly 10 also includes a stabilizing plate 1004, a load-bearing plate 1005 and bolts 1006, a stabilizing plate 1004 is arranged on the inner side of the nut seat 1003, two stabilizing plates A load-bearing plate 1005 is installed between the fixed plates 1004, and bolts 1006 are arranged on the surface of the load-bearing plate 1005. The arrangement of the mounting assembly 10 can prompt the motor 1001 to start running by controlling the switch when the equipment is installed. When the motor 1001 is running, it prompts the threaded rod 1002 to rotate clockwise. In this way, during the rotation process, the nut seat 1003 drives the stabilizing plate 1004 to adjust the height along the surface of the mounting back plate 8, so that after adjusting to the required position, the equipment is fixed to the wall by bolts 1006, which can be suitable for installation at different positions to support the bridge frame.

[0025] Specific implementation method: When installing the bridge, it is necessary to use a bracket to distribute its weight. At this time, the fixing plate 401 and the plug plate 402 are fixedly installed. The locking frame 403 is opened by pressing the fixing buckle 404. After opening, the plug plate 402 is inserted into the locking frame 403. Then, after inserting it into the interior, the motor 1001 is started to run by controlling the switch. When the motor 1001 runs, the threaded rod 1002 rotates clockwise. In this way, during the rotation process, the nut seat 1003 drives the stabilizing plate 1004 to adjust the height along the surface of the mounting back plate 8, so that after adjusting to the required position, the equipment is fixed to the wall by bolts 1006. During the installation process, the fixing mounting plate 401 can play a role in thickening and protecting the supporting bracket 1. Then the workers When the staff needs to support the bridge, the weight can be shared by the support bracket 1. When the area of ​​the bridge is large, the two-way driving machine 701 can be used to drive the positive and negative screw rods 703 to rotate clockwise inside the hollow frame 702. During the rotation, the moving block 704 drives the connecting rod 705 to slide along the surface of the positive and negative screw rods 703. Secondly, during the sliding process, the electric push plate 706 pushes the extension plate 707 from the inside to the outside along the inside of the support bracket 1, thereby expanding the use area of ​​the support bracket 1. In this way, the support bracket 1 and the extension plate 707 can be used in combination to support a larger area of ​​the bridge. On the contrary, when it is small, the extension plate 707 can be stored on the inner side of the support bracket 1. At the same time, after installation, the lines required for the bridge need to be placed on the transverse connecting rod 2 and the storage plate 5 along the lead hole 3, so that the device can be used more conveniently.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
