Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical assembly, and relates to a linear height-adjustable support bracket and a method of use, which is mainly used to assist in completing the ground support work of large / high-weight cylindrical finished products, so that the operator can safely perform related work around the finished products. Background Art

[0002] During the mechanical assembly process, for large and heavy cylindrical products, operators are also required to assemble various functional components such as various cables, conduits, small finished products, etc. inside and outside. Therefore, this requires that large and heavy cylindrical finished products cannot directly touch the ground, but are suspended by other devices and separated from the ground to a certain height until the operator's optimal installation height is met. Therefore, the device that lifts it must have functions such as high strength and good flexibility. At present, the conventional method and tooling is to lift the main structure of large / high-weight finished products from the structural installation area to the small cable, conduit, and finished product area through a ceiling crane, and then the operator uses N ordinary brackets to slowly raise the ordinary brackets by hand, and then lift them one by one. Although the above method can also meet the installation work of the large / high-weight cylindrical finished products, it also reflects some room for improvement. First, because the previous bracket tray is manually lifted by the operator, affected by the age and weight of the bracket itself, it requires 2 operators to operate a lifting screw rod to complete this work, which not only increases the difficulty of the work, but also increases the intensity of the work. Secondly, the entire lifting work requires more than two operators to complete, which invisibly increases the number of people working and the work efficiency is not high. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a linear height-adjustable support bracket, which uses an electric device to replace manual operation, starting from how to reduce work intensity, improve work efficiency, and reduce the number of operators, replacing the previous purely manual and bulky bracket device.

[0028] Beneficial effects of the present invention:

[0029] Starting from the special design highlights, we will introduce them one by one - work efficiency, accuracy, scope of application, structural particularity, stability, versatility, and service life:

[0030] (1) The present invention has a novel mechanical structure, a high degree of semi-automation, and a strong comprehensive auxiliary assembly capability. The number of operators is reduced from the original three to the current one, and an electric drive device is used to replace the manual adjustment of the bracket height, thereby reducing labor intensity.

[0031] (2) The highlight of the present invention is that the electric drive device 12 adopts a stepper motor as a power element, which can realize the rotation of the rotating support rod 3 within a very small rotation angle range, thereby making the rising height of the entire bracket in a linear adjustment state. This will prevent the bracket from rising too quickly and increase the difficulty of adjustment during the docking process between the bracket and the finished product.

[0032] (3) Another highlight of the present invention is that three rotating struts 3 are provided, and the middle rotating strut is used to drive the other two rotating struts to rise synchronously. Compared with the previous manual operation, it ensures that the entire bracket will not get stuck during the rising process, thereby reducing the difficulty and intensity of the operation.
