DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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 in conjunction with the accompanying drawings.

[0032] Combination Figure 1-Figure 8 A subway busbar erection buffer suspension bracket system of the present invention includes a suspension keel frame 11, the suspension keel frame 11 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, the bottom end of the angle steel 12 is installed with a pressure edge strip 13, the upper surface of the pressure edge strip 13 is connected with 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 end 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, and the two groups of pressure edge strips 13 are connected through 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, and the upper surface of the crossbeam frame 16 is installed A clamping sleeve 19 is provided, and a cable busbar 18 is embedded inside the clamping sleeve 19. An upper sleeve clamp 17 is connected to the top of the clamping sleeve 19. 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 an annular structure, forming a stable suspension bracket system, which can effectively support and fix the cable busbar 18 to ensure 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 the construction efficiency and the convenience of later maintenance.

[0033] When fixing the cable busbar 18, the cable busbar 18 is first embedded into the interior of the positioning ring 32, and then the cable busbar 18 is embedded into the interior of the clamping sleeve 19, and then the clamping sleeve 19 and the upper sleeve clamp 17 are connected together through the 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 the cost.

[0034] Due to the influence of the application environment, some cables on the suspension frame 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, and thus there will be a problem of 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 cable. The specific operations are as follows:

[0035] A buffer assembly 2 is installed on the bottom surface of the suspension keel frame 11, and the buffer assembly 2 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 A positioning ring 32 is connected to one side surface of 1, and the positioning ring 32 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 mode 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 a complex subway operation environment.

[0036] A slide groove is provided inside the leveling plate 22, and the leveling plate 22 and the angle steel 12 are maintained in sliding connection through the slide groove. A positioning wheel 33 is connected to the slide groove provided in the leveling plate 22, and the positioning wheel 33 is fixedly connected to the slide groove provided in the leveling plate 22 through a mounting frame. The positioning wheel 33 fits on the surface of the angle steel 12. The slide groove and the positioning wheel 33 ensure that the leveling plate 22 slides smoothly on the angle steel 12, which can not only enable the leveling plate 22 to flexibly adjust its position when it is vibrated, but also limit its movement within a certain range to avoid structural damage caused by 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 avoid the vibration from affecting the cable bus 18, the edge strip 13 and the cross beam frame 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 frame 16, which plays a certain degree of buffering role relative to the cross beam frame 16.

[0038] Secondly, the force generated by part of the vibration is transmitted 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 relieved. The buffer spring 21 can absorb and disperse energy through elastic deformation. After being relieved, the force is transmitted to the universal ball head 23, and then transmitted to the positioning block 31 and the crossbeam frame 16 by the suspension rod 26. After layers of progressive, the force is fully relieved, 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-level buffer system, which can gradually weaken the impact force generated by vibration and protect the cable bus 18 from vibration damage 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 vibrated, the upper and lower positions fluctuate. At this time, the force is transmitted to the buffer spring 21. The buffer spring 21 absorbs and disperses the impact force of the vibration, and then transmits the relieved force to the adjustment plate 22, and finally transmits it to the cable bus 18 by the adjustment plate 22. In this way, the impact of the vibration on the cable bus 18 is greatly reduced;

[0040] The bottom end of the adjustment 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 laterally arranged 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, this 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 slide groove of the adjusting plate 22 is also fixedly connected with a connecting component 4, which includes a connecting block 41, which is fixedly connected to the inner wall of the slide groove of the adjusting plate 22, and 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 with a plug rod 43, and the plug rod 43 is embedded with a connecting head 42. The connecting block 41 is composed of a plurality of connecting blocks 41, a connecting head 42 and a plug rod 43. 1 is fixedly connected with a buffer pad 44, 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 of the outer walls 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] In order to avoid the influence of the vibration of the suspension keel frame 11 on the adjustment plate 22, a connection component 4 is set between the suspension keel frame 11 and the adjustment plate 22, which not only ensures the connection between the two, but also avoids the influence of the vibration on the adjustment plate 22. When the suspension keel frame 11 vibrates, the generated force is transmitted to the connection block 41. In addition, the connection block 41 forms a U shape, which has good buffering performance. When the suspension keel frame 11 vibrates, for example, when the suspension keel frame 11 moves to the left, the U-shaped structure formed by the connection block 41 will be deformed, so that part of the force can be absorbed. Due to the left and right swing of the vibration direction, when the suspension keel frame 11 moves to the left, the connection block 41 absorbs the force. When it moves to the right, the force accumulated in the connection block 41 is released again. In this way, the vibration of the suspension keel frame 11 will not affect the adjustment plate 22, so that the adjustment plate 22 is more stable. When the adjustment plate 22 is stable, the cable bus 18 can also be more stable.

[0043] When the leveling plate 22 is moved up and down by the force, the connecting block 41 can also be used to roll to adapt to this process, ensuring that the movement of the crossbeam frame 16 is not restricted.
