DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-5 As shown in the figure, a kind of vibration coal feeder hanging device, including fixed support 1, fixed support 1 is made of channel steel or I-beam support structure, the lower portion of fixed support 1 is provided with pressing plate 2, the surface of fixed support 1 and pressing plate 2 is respectively provided with two groups of through holes 3, inverted U-shaped hanging rod 4 is inserted in through hole 3, hanging rod 4 includes main rod body 41, T-shaped connecting head 42 is fixedly arranged at the both ends of main rod body 41, threaded cylinder 44 is slidably connected to the outside of connecting head 42, upper thread and lower thread are formed on the surface of threaded cylinder 44, the thread direction of upper thread and lower thread is opposite, nut 6 is respectively threadedly connected on upper thread and lower thread, gasket 7 is respectively arranged on the opposite side of two nuts 6, the clearance between hanging rod 4 and fixed plate through hole 3 is 1mm, which reduces the horizontal displacement of hanging rod 4.

[0024] Specifically, fixed support 1 is pre-installed in appropriate position by welding or bolt connection, to improve reliable suspension point of coal feeder in working process, when installing, steel wire rope is passed through hanging rod 4, hanging rod 4 is passed through pressing plate 2 and fixed support 1 along through hole 3, and is fixed by screwing two nuts 6 on pressing plate 2 and fixed support 1, the device changes single-point force into double-point force by adopting U-shaped hanging rod 4, disperses stress point, can satisfy vertical stress and horizontal stress, changes single-side fastening of bolt into double-side fastening, further strengthens horizontal stress of hanging rod 4, so that shear damage of hanging rod 4 connecting hole position caused by horizontal movement is greatly reduced.

[0025] The length of connecting head 42 is greater than the length of threaded cylinder 44, spring part 45 is arranged above threaded cylinder 44, spring part 45 is sleeved on the outside of connecting head 42, spring part 45 adopts rubber spring, and rubber spring has good damping performance.

[0026] Specifically, when the coal feeder vibrates, the connector 42 slides along the threaded cylinder 44, and the spring 45 can absorb some of the vibration energy, reducing the impact of vibration on the support structure and surrounding equipment.

[0027] The surfaces of the connector 42, the threaded cylinder 44, and the nut 6 are fitted with a fixing component 8. The fixing component 8 includes several slots 81, which are formed on the inner side wall of the nut 6. The fixing component 8 also includes several U-shaped mounting slots 82, which are formed on the inner wall of the threaded cylinder 44. The threaded cylinder 44 has four mounting slots 82 inside. The mounting slots 82 are slidably connected to the inside of the mounting slots 82. The outer side wall of the mounting slots 83 is fitted with a limiting spring 84. The fixing component 8 also includes several annular grooves 85, which are formed on the surface of the connector 42.

[0028] Specifically, the thrust applied to the connecting rod by the spring 45 causes the lower end of the threaded cylinder 44 to abut against the upper end of the main rod 41. When the lower end of the threaded cylinder 44 abuts against the upper end of the main rod 41, the annular groove 85 corresponds to the mounting groove 82, allowing the locking pin 83 to be inserted into the annular groove 85 by the elastic force of the limiting spring 84, while the other end is retracted into the mounting groove 82. This prevents the locking pin 83 from protruding and affecting the installation of the nut 6. After the lifting rod 4 is installed, the tension applied to the main rod 41 by the wire rope causes the connecting head 42 to descend, causing the annular groove 85 to be misaligned with the mounting groove 82. The connecting head 42 then pushes the locking pin 83 to move outward, allowing the locking pin 83 to be accurately inserted into the locking groove 81 of the nut 6, thereby locking the nut 6 and preventing the nut 6 from loosening and affecting the stability of the device.

[0029] Working principle: During installation, the wire rope is passed through the hanger 4, and the hanger 4 is passed through the through hole 3 through the pressure plate 2 and the fixed bracket 1. It is then fixed by tightening the two nuts 6 on the upper and lower parts of the pressure plate 2 and the fixed bracket 1. This device uses a U-shaped hanger 4 to change the original single-point force to double-point force, distributing the force points. It can meet both vertical and horizontal force requirements. The bolt is tightened from one side to both sides, which further strengthens the horizontal force of the hanger 4, thereby greatly reducing the shear damage to the connection hole of the hanger 4 caused by horizontal movement.

[0030] After the boom 4 is installed, the tension applied to the main boom 41 by the wire rope drives the connector 42 to descend, causing the annular groove 85 to be misaligned with the mounting groove 82. The connector 42 then pushes the locking pin 83 to move outward, so that the locking pin 83 is accurately inserted into the locking groove 81 of the nut 6, thereby locking the nut 6 and preventing the nut 6 from loosening and affecting the stability of the device.
