Description

Technical Field

[0001] The invention relates to the technical field of integrated support and hanger brackets, and in particular to a support and hanger bracket mounting seat and a preparation method thereof. Background Art

[0002] Traditional integrated supports and hangers are mostly composed of C-shaped grooves and connectors. The C-shaped groove serves as a hanger, and connection and adjustment are achieved through threaded cooperation with angle connectors or locks. The engaging surface of the C-shaped groove hanger of the traditional integrated support and hanger is set on the inner side of the C-shaped groove curling edge or the outer side of the flange. The top of the hanger is anchored by a flat ear plate or threadedly connected with the anchor bolt. The installation height of the hanger cannot be quickly adjusted during use. When the top of the structure is uneven, it is difficult to achieve leveling of the support and hanger beam.

[0003] Chinese utility model patent CN215371946U discloses an easily retractable flexible earthquake-resistant support and hanger, comprising a storage box, wherein vertical rods are fixedly installed on the top of the inner cavity of the storage box near both sides, and hangers are movably sleeved on the outer sides of the two vertical rods, and racks are fixedly installed on the rear sides of the hangers, and a transmission rod is movably installed in the inner cavity of the storage box, and two gears are fixedly sleeved on the outer sides of the transmission rod, and the gears are meshed with the racks, and screw holes are opened on one side of the two hangers at equal distances; through the meshing of the gears and the racks, when the transmission rod causes the gears to rotate, the racks will move up and down, thereby allowing the hangers to move up and down, and the hangers can be fixed to the storage box through the cooperation between the bolts and the screw holes, thereby solving the problem that the height of the support and hanger cannot be adjusted according to different equipment installation requirements. However, the meshing contact surface of conventional gears and racks is small, and the teeth are easily covered by materials after surface treatment such as hot-dip galvanizing, and slippage is easy to occur on the meshing contact surface, resulting in low overall bearing capacity and reliability of the support bracket. After the hanger is moved into place, it needs to be connected with the screw holes equidistantly opened on the hanger through bolts. Therefore, only the equidistant adjustment of the hanger height can be achieved in practice. The adjustable height is related to the spacing between the screw holes, and fine-tuning cannot be achieved. When the top of the structure is uneven, it is still difficult to level it. Summary of the invention

[0004] The purpose of the present invention is to overcome the problem in the prior art that the integrated support and hanger bracket realizes height adjustment through the meshing of conventional gears and racks, resulting in insufficient bearing capacity and reliability, and the inability to meet the deficiency of fine-tuning the height of the hanger rod through the connection with bolts and screw holes, and to provide a support and hanger bracket mounting seat and a preparation method thereof.

The top plate 11 and the side plate 12 have a simple structure, a clear force transmission path, and can effectively transmit vertical loads vertically, thereby improving the bearing capacity and reliability of the mounting seat. When in use, the adapter seat 3 can be moved in and / or out transversely relative to the connecting seat 1 along the extension direction of the first strip-shaped tooth 2.

[0066] In an optional embodiment, if Figure 5 As shown, the cross-section of the first strip tooth 2 can be a right triangle or a right trapezoid.

[0078] In an optional embodiment, the connecting member 5 and the docking hole 32 are threadedly connected.

[0079] In an optional embodiment, the connecting member 5 applies a pulling force to the connecting seat 1, the adapter seat 3 and the suspension rod 6, and can pull the side panel 12 and the wall panel 31 to fit together. The vertical load of the suspension rod 6 is transferred to the adapter seat 3 through its connecting action, and the adapter seat 3 then forms a bite state through the upper and lower overlapping connection of the first bar teeth 2 and the second bar teeth 4, thereby increasing the bite depth of the first bar teeth 2 and the second bar teeth 4, expanding the area of ​​the horizontal overlapping surface, and realizing the stable upward transmission of the vertical load of the suspension rod 6, so that the vertical load transfer path of the suspension rod 6 is stable and direct, and is not easy to change during use.

[0115] In an optional implementation, step S6 is performed after the stress elimination is completed, by moving the workpiece into the pin pulling station to perform a one-time pin pulling process.

[0116] S7. After grinding and cleaning, perform Dacromet surface treatment.

[0117] In an optional implementation, step S7 can be used to clean the edge burrs to prepare for subsequent Dacromet surface treatment.

[0118] A method for preparing a support bracket mounting seat in this embodiment uses hot-rolled plate welding to prepare a connecting seat and an adapter seat. It has a simple structure and can improve the preparation quality, improve the structural strength and reliability of the mounting seat. At the same time, a pin drawing process is used to process each bar tooth with high processing accuracy, which can ensure the structural strength of each bar tooth and ensure the effective transfer of vertical loads.

[0119] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
