[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.
[0032] Combine Figures 1-8 The present invention provides a buffer suspension bracket system for erecting a subway busbar, including a suspension keel frame 11, which is used to be suspended on a wall. The bottom end of the suspension keel frame 11 is fixedly connected to an angle steel 12, and a pressure edge strip 13 is installed at the bottom end of the angle steel 12. The upper surface of the pressure edge strip 13 is connected to a shock absorber 14 and a traction rope 15. The shock absorber 14 and the traction rope 15 are arranged in parallel on the pressure edge strip 13. The top of the shock absorber 14 is connected to a crossbeam frame 16. The crossbeam frame 16 is arranged between two groups of pressure edge strips 13. The two groups of pressure edge strips 13 are connected by the crossbeam frame 16. The suspension rod 26 passes through the interior of the positioning block 31, and its bottom end is fixedly connected to the crossbeam frame 16. The upper surface of the crossbeam frame 16 is installed There is a clamping sleeve 19, and a cable busbar 18 is embedded in the interior of the clamping sleeve 19. The top of the clamping sleeve 19 is connected to the upper sleeve clamp 17. The upper sleeve clamp 17 and the clamping sleeve 19 are used to fix the cable busbar 18. The suspension rod 26 and the positioning block 31 are longitudinally slidably connected. The cable busbar 18 passes through the interior of the upper sleeve clamp 17 and the clamping sleeve 19 and the interior of the positioning ring 32. The upper sleeve clamp 17 and the clamping sleeve 19 form a ring structure, forming a stable suspension bracket system, which can effectively support and fix the cable busbar 18, ensuring its safe and stable operation in the subway environment. At the same time, the connection method of each component is convenient for installation and maintenance, which improves construction efficiency and convenience of later maintenance.
[0033] When fixing the cable busbar 18, the cable busbar 18 is first embedded in the interior of the positioning ring 32, and then the cable busbar 18 is embedded in the interior of the clamping sleeve 19, and the clamping sleeve 19 and the upper sleeve clamp 17 are connected together by a fixing piece. In this way, the cable busbar 18 is fixed. Compared with the traditional design, the cable busbar 18 is exposed outside, which is convenient for maintenance and reduces costs.
[0034] Due to the influence of the application environment, some cables on the suspension brackets will be affected by the vibration caused by the train running. Long-term exposure to such an environment will cause the cables to resonate, which will cause the cable joints to become loose to varying degrees, resulting in unstable contact. In order to solve this problem, a corresponding buffer structure is provided on the buffer component 2 to avoid resonance and improve the protection of the cables. The specific operation is as follows:
[0035] The bottom surface of the suspension keel 11 is installed with a buffer assembly 2, which includes a buffer spring 21. The bottom end of the buffer spring 21 is connected to an adjustment plate 22. The adjustment plate 22 is sleeved on the angle steel 12 and maintains a sliding connection with the angle steel 12. The bottom end of the adjustment plate 22 is connected to a universal ball head 23. The bottom end of the universal ball head 23 is connected to a suspension rod 26. The bottom end of the suspension rod 26 is movably connected to a positioning assembly 3. The positioning assembly 3 includes a positioning block 31. The bottom end of the suspension rod 26 is movably connected to the positioning block 31. The positioning block 3 1 is connected to a positioning ring 32, which is sleeved on the outer surface of the cable busbar 18; the design of the buffer component 2 can gradually buffer and disperse the vibration of the suspension keel frame 11, absorb energy through the elastic deformation of the buffer spring 21, and the sliding of the adjustment plate 22 and the connection method of the universal ball head 23 can effectively change the transmission direction and strength of the vibration, reduce the direct impact on the cable busbar 18, and ensure that the cable busbar 18 can maintain a relatively stable state in the complex subway operation environment.
[0036] A sliding groove is provided inside the adjusting plate 22, and the adjusting plate 22 and the angle steel 12 are kept in sliding connection through the sliding groove. A positioning wheel 33 is connected to the sliding groove provided in the adjusting plate 22, and the positioning wheel 33 is fixedly connected to the sliding groove provided in the adjusting plate 22 through a mounting bracket. The positioning wheel 33 fits on the surface of the angle steel 12. The sliding groove and the positioning wheel 33 ensure that the adjusting plate 22 slides smoothly on the angle steel 12, which can not only enable the adjusting plate 22 to flexibly adjust its position when it is vibrated, but also limit its movement within a certain range to avoid structural damage due to excessive displacement.
[0037] When the train passes, the vibration generated will directly affect the suspension keel frame 11 and the angle steel 12. This is because the suspension keel frame 11 and the angle steel 12 are in a rigid connection with the wall. When the vibration affects the wall, the vibration is also transmitted to the suspension keel frame 11 and the angle steel 12. In order to prevent the vibration from affecting the cable bus 18, the edge strip 13 and the cross beam 16 are first connected through the shock absorber 14. After the shock absorber 14 is connected, the vibration force on the angle steel 12 will be transmitted to the edge strip 13, and the paper force will be transmitted to the shock absorber 14. When the shock absorber 14 absorbs the vibration, it will slowly be transmitted to the cross beam 16, thereby playing a certain degree of buffering role relative to the cross beam 16.
[0038] Secondly, part of the force generated by the vibration is transferred to the buffer spring 21, which drives the adjustment plate 22 at the bottom of the buffer spring 21 to move. In the process of force transmission, the force is alleviated. The buffer spring 21 can absorb and disperse energy through elastic deformation. After being alleviated, the force is transferred to the universal ball head 23, and then transferred to the positioning block 31 and the crossbeam 16 by the suspension rod 26. After layers of progressive, the force is fully alleviated, so that the impact force of the force on the cable bus 18 is also alleviated. The synergistic effect of the buffer spring 21 and other components forms a multi-stage buffer system, which can gradually weaken the impact force generated by the vibration and protect the cable bus 18 from damage by vibration to the greatest extent. This progressive buffering method makes the entire suspension bracket system have good buffering performance.
[0039] For example, when the suspension keel frame 11 is subjected to vibration and its vertical position fluctuates, this force is transmitted to the buffer spring 21. Through the absorption and dispersion of the buffer spring 21, the impact of the vibration is relieved. The relieved force is then transmitted to the leveling plate 22, and finally transmitted to the cable bus 18 by the leveling plate 22. In this way, the impact of the vibration on the cable bus 18 is greatly reduced.
[0040] The bottom end of the leveling plate 22 is also connected to a side strip 24, and a support rod 25 is connected to one side surface of the side strip 24. The side of the support rod 25 away from the side strip 24 is connected to the suspension rod 26. The support rod 25 is arranged in an S shape and is arranged laterally between the suspension rod 26 and the side strip 24. The arrangement of the support rod 25 increases the stability of the suspension rod 26. When the cable bus 18 is suspended, if the cable bus 18 shakes, it will also have a certain impact on the stability of the cable bus 18. Therefore, when the cable bus 18 shakes, the crossbeam frame 16 will also shake, and then drive the positioning block 31 and the suspension rod 26. The suspension rod 26 is pulled by the support rod 25, so that the vibration generated by the cable bus 18 can be quickly released, which can also make the cable bus 18 more stable.
[0041] The adjusting plate 22 is also fixedly connected to the connecting component 4, which includes a connecting block 41. The connecting block 41 is fixedly connected to the inner wall of the adjusting plate 22. The other end of the connecting block 41 is connected to the angle steel 12. The connecting block 41 is used to connect the angle steel 12 and the adjusting plate 22. The two ends of the connecting block 41 are fixedly connected to the plug rod 43. The plug rod 43 is embedded with a connecting head 42. The connecting block 41 is composed of multiple groups of connecting blocks 41, connecting heads 42 and plug rods 43. The connecting block 41 is composed of multiple groups of connecting blocks 41, connecting heads 42 and plug rods 43. 1 is fixedly connected to the inner wall of the frame 1, and the upper and lower buffer pads 44 correspond to each other. The connecting block 41 rotates along the connecting head 42 as the axis, and the buffer pads 44 are completely fitted together. One outer wall of the connecting block 41 is supported on the surface of the angle steel 12, and the other outer wall is supported on the adjustment plate 22. The connecting block 41 is set in the gap between the angle steel 12 and the adjustment plate 22. The support rods 25 are evenly distributed on the surface of the side strips 24, and the bending direction of the side strips 24 is always perpendicular to the ground.
[0042] When the keel frame 11 is in a state of vibration, the U-shaped structure formed by the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed.

When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block 41 is deformed, and a part of the force is absorbed. When the keel frame 11 is in a state of vibration, the connecting block
[0043] When the leveling plate 22 is moved up and down by the force, the connecting block 41 can also be rolled to adapt to this process, ensuring that the movement of the crossbeam 16 is not restricted.
