Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical engineering equipment, and more specifically to a sliding bracket shaft structure. Background Art
[0002] The existing sliding bracket shaft structure has the defect of insufficient load capacity. The structural design of the bracket and the shaft may not be reasonable enough and the load distribution is not fully considered, resulting in excessive stress at certain points. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a sliding bracket shaft structure to solve the defect of insufficient load capacity of the existing sliding bracket shaft structure in the above-mentioned background technology, and the structural design of the bracket and the shaft may not be reasonable enough, and the load distribution is not fully considered, resulting in the problem of excessive stress at certain points.
[0004] The utility model provides the following technical solutions: a sliding bracket shaft structure, including an equipment support beam, a plurality of shaft structures are fixedly installed on the top of the equipment support beam, a mounting beam is fixedly installed on the top of each of the shaft structures, a threaded groove is provided on each of the mounting beams, a sliding guide rail is fixedly installed on the bottom end of the equipment support beam, a structural reinforcement rib is fixedly installed at the connection between the sliding guide rail and the equipment support beam, a sliding groove is provided at the bottom end of the sliding guide rail, a sliding slider is slidably installed on the sliding groove at the bottom end of the sliding guide rail, and a shaft structure is movably installed on the bottom end of the sliding slider. When in use, multiple equipment lifting rods and installation beams fixedly installed on the equipment support beam bear the overall load-bearing function. When the equipment support beam is loaded, multiple equipment lifting rods and installation beams can share the gravity at the same time to prevent all of them from falling off and causing an accident. In addition, structural reinforcement ribs are installed at the connections between the equipment support beam and the sliding guide rail for structural reinforcement, which further enhances the overall stress stability of the structure and prevents excessive stress in one place. In actual use, it effectively solves the defect of insufficient load capacity of the existing sliding bracket shaft structure. The structural design of the bracket and the shaft may not be reasonable, and the load distribution is not fully considered, resulting in the problem of excessive stress at some points.
[0005] Furthermore, the structural corners of the sliding guide rails are all processed by a grinding process to make streamlined arc transitions. When in use, after a metal workpiece is subjected to a large load, internal stress begins to distribute. Once the metal workpiece has too many sharp corners, the internal stress will be concentrated in these places, causing premature fatigue of the metal in these places and structural damage. Therefore, making arc transitions at all sharp places can better avoid this from happening.
[0006] Furthermore, an auxiliary anti-falling block is fixedly installed on the top of the sliding slider, a sliding groove is provided on the top of the sliding guide rail, and the auxiliary anti-falling block is slidably installed in the sliding groove on the top of the sliding guide rail. When in use, when the sliding slider fails, the auxiliary anti-falling block can not only prevent the sliding slider from falling, but also drive the sliding slider to continue to slide on the sliding guide rail to prevent the complete shutdown after actual work.
[0007] Furthermore, a first shaft mounting plate is fixedly mounted on the bottom end of the sliding block, a second shaft mounting plate is fixedly mounted on the bottom end of the first shaft mounting plate via a threaded rod, a ball shaft is fixedly mounted on the top end of the shaft structure, and the ball shaft is arranged inside the first shaft mounting plate and the second shaft mounting plate. When in use, the shaft structure, the ball shaft, the first shaft mounting plate, and the second shaft mounting plate form a ball hinge structure. The force uniformity of the ball hinge in engineering mechanics is far superior to that of an ordinary cylindrical shaft. It can not only effectively share the force evenly, but also has a stable structure and is not prone to failure.
[0008] Furthermore, the equipment support beam, equipment hoisting rod, mounting beam, sliding guide rail, and structural reinforcement ribs are all made of a mixed alloy of recyclable stainless steel and tungsten steel metal, and the contact surfaces of the first shaft mounting plate, the second shaft mounting plate, and the shaft structure are evenly coated with lubricating oil. When in use, the composite alloy used in the equipment support beam, the equipment hoisting rod, the mounting beam, and the sliding guide rail has a stronger structural strength than a single alloy, and can be recycled and reused after the service life expires. The lubricating oil between the first shaft mounting plate, the second shaft mounting plate, and the shaft structure can enhance the service life of the shaft structure.
[0009] Technical effects and advantages of the utility model:
[0010] 1. The utility model is provided with an equipment lifting rod, a mounting beam, a sliding guide rail, a structural reinforcement rib, a sliding slider, and a rotating shaft structure, which effectively solves the defect of insufficient load capacity of the existing sliding bracket rotating shaft structure in actual use. The structural design of the bracket and the rotating shaft may not be reasonable enough, and the load distribution is not fully considered, resulting in excessive stress at certain points.
[0011] 2. The utility model is provided with an auxiliary anti-falling block. When in use, when the sliding slider fails, the auxiliary anti-falling block can not only prevent the sliding slider from falling, but also drive the sliding slider to continue sliding on the sliding guide rail to prevent the sliding slider from completely shutting down after actual work.
