Description

TECHNICAL FIELD

[0001] The utility model relates to a blast fan damping seat technical field, concretely is a damping base structure of magnetic suspension blast fan. BACKGROUND

[0002] The traditional magnetic suspension blast fan is usually placed directly on the ground through the supporting leg without any damping device. This installation method has obvious problems when it is close to other large units, because the vibration generated by the large units during operation can easily cause the shaft inside the magnetic suspension blast fan to deviate, causing wear and even damage. In addition, due to the lack of effective damping measures, the vibration generated by the magnetic suspension blast fan during operation can also cause damage to the connected pipes and other components.

The triangular block on the guide assembly moves up and down flexibly, so that the longitudinal spring shock absorber reduces the longitudinal vibration force, the movement of the crossbar left and right makes the transverse spring shock absorber work to reduce the transverse vibration force, thereby achieving simultaneous reduction of the longitudinal and transverse vibration forces generated by the blast fan, and increasing the damping effect on the blast fan.

[0004] The above-mentioned device can not completely and effectively eliminate vibration during use, especially during the start and stop of the magnetic suspension blast fan, which can generate a large amount of instantaneous vibration and impact force.

However, in the prior art, the damping base structure of some magnetic suspension blast fans cannot be installed on different models of magnetic suspension blast fans, which can cause displacement, shaking or even tilting of the device on the damping base, which not only damages the device itself, but also endangers the safety of the surrounding workers and equipment

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 scope of protection of the utility model.

[0023] Embodiment one

[0024] Please refer to Figures 1-4 In the embodiment, the damping base structure of the magnetic suspension blower fan comprises a base 1, two buffer tabs 2 are arranged in the base 1, the bottom end of the lower end buffer tab 2 is fixedly connected to the inner wall of the bottom end of the base 1, the bottom end of the upper end buffer tab 2 is fixedly connected to a limiting plate 3, the outer part of the upper end buffer tab 2 is slidingly connected to the top end inner wall of a crossbar 6, a damping rod one 4 is fixedly connected to the side close to the two buffer tabs 2, a spring 5 is arranged outside the damping rod one 4, a crossbar 6 is arranged outside the two buffer tabs 2, openings 7 are arranged on the left and right sides of the crossbar 6, movable blocks 8 are slidingly connected inside the two openings 7, connecting rods 9 are fixedly connected inside the two movable blocks 8, swing arms one 10 are rotatably connected to the front and back sides of the two connecting rods 9, the bottom end inner walls of the plurality of swing arms one 10 are rotatably connected outside the lower end plurality of anchor bolts 13, two swing arms two 11 are arranged on the side close to the two swing arms one 10, the top end inner walls of the plurality of swing arms two 11 are rotatably connected outside the top end plurality of anchor bolts 13, connecting blocks 12 are fixedly connected to the left and right sides of the two buffer tabs 2, anchor bolts 13 are fixedly connected inside the plurality of connecting blocks 12, damping rods two 14 are fixedly connected to the left and right sides of the base 1, buffer springs 15 are arranged outside the two damping rods two 14, and an adjusting mounting assembly is fixedly connected to the top end of the base 1.

[0025] When the magnetic levitation blower works to generate vertical vibration, the vibration is first transmitted to the base 1, and the two buffer lugs 2 inside the base 1 play a role. Since the lower end buffer lug 2 is fixed to the inner wall of the bottom end of the base 1, and the upper end buffer lug 2 can slide on the inner wall of the top end of the crossbar 6, the vertical vibration causes the two buffer lugs 2 to move relative to each other, and the spring 5 is compressed or stretched when the two buffer lugs 2 move relative to each other, absorbing vibration energy through elastic deformation, and the damping rod one 4 suppresses the excessive oscillation of the spring 5, so that the vibration energy is quickly dissipated, thereby achieving vertical shock absorption; the horizontal vibration causes the crossbar 6 to produce horizontal displacement inside the base 1. The movable block 8 in the opening 7 on the left and right sides of the crossbar 6 moves accordingly, the movable block 8 drives the connecting rod 9 to move, the connecting rod 9 rotates the swing arm one 10 and the swing arm two 11 connected by the anchor bolt 13 and the connecting block 12, and the swing arm one 10 and the swing arm two 11 will swing with the movement of the connecting rod 9. This swing changes the direction of transmission of the vibration, and the interaction between multiple swing arms further disperses the vibration energy. The damping rod two 14 fixed on the left and right sides of the crossbar 6 and the buffer spring 15 outside the damping rod two 14 also have a buffering effect on the horizontal displacement of the crossbar 6. The buffer spring 15 absorbs horizontal vibration energy through elastic deformation, and the damping rod two 14 suppresses the excessive oscillation of the buffer spring 15, thereby achieving horizontal shock absorption.
