Description

Technical Field

[0001] The utility model relates to the technical field of large-scale fan shock absorption, and specifically to a large-scale side fan shock absorption assembly. Background Art

[0002] Large side blowers will generate large vibrations during operation and transportation, and need to be damped and noise-reduced through some shock-absorbing connections. It is also necessary to ensure that they will not undergo large displacements during normal operation, and that the connection between the product and the vehicle will not be completely disconnected under the extreme conditions of the blower's rotation.

[0003] The large side blower is rigidly connected to the transfer vehicle. When the blower is running, the speed is high, and the vibration and noise are large. During long-term use, the bolts used to connect the blower often loosen, causing the side blower to separate from other objects, resulting in the side blower being unable to work and operate normally. Large side blowers usually use a shock-absorbing assembly to reduce the vibration between the side blower and other objects. In the prior art, the shock-absorbing assembly usually uses an upper plate, a lower plate and a shock-absorbing layer structure to reduce the vibration between the large side blower and other objects. However, the upper plate, the lower plate and the shock-absorbing layer are also rigidly connected with bolts. The shock-absorbing layer needs to be connected to the large side blower. If the shock-absorbing layer is made of a flexible material, the large side blower will be unstable. If the shock-absorbing layer is made of a rigid material, the connection between the large side blower and the shock-absorbing layer will also be easy to loosen. Utility Model Content

[0033] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0034] Reference Figure 1 to Figure 7The utility model proposes a large side wind turbine shock absorbing assembly, including an upper plate 100 and a lower plate 200, and also includes a rubber layer 300 arranged between the upper plate 100 and the lower plate 200. The upper plate 100, the lower plate 200 and the rubber layer 300 are vulcanized and bonded together.

[0035] In this embodiment, the lower plate 200 is used to connect with other objects, and the upper plate 100 is connected to the top of the large side blower. The upper plate 100 and the lower plate 200 are vulcanized and bonded together with a rubber layer 300, which not only saves the connecting parts between the upper plate 100 and the lower plate 200 and avoids the loosening of the rigid connecting parts due to use time, but also the large side blower is connected to the upper injected rubber plate 100, and the connecting surface is more stable. The rubber layer 300 and the upper and lower plates 200 do not rely on rigid connection, and the vibration generated by the large side blower will not cause the bolts inside the shock absorbing device to loosen.

[0036] Furthermore, the upper plate 100 has a plurality of glue injection holes 110, and the glue injection holes 110 are used for.

[0037] In this embodiment, the upper plate 100 is provided with a plurality of glue injection holes 110. After the upper plate 100 and the lower plate 200 are placed in a fixed position, a glue injection mold is installed, and then rubber is injected from the glue injection holes 110 using a rubber glue injection machine, so that the upper plate 100, the lower plate 200 and the rubber layer 300 can be vulcanized and bonded together. The setting of the glue injection holes 110 of the upper plate 100 allows the upper plate 100 and the lower plate 200 to be fixed in position by a mold first, and then the rubber layer 300 in the middle is formed by glue injection. The production method is simple, and the upper plate 100, the lower plate 200 and the rubber layer 300 are bonded together by rubber vulcanization, the connection is stable, and the shape of the rubber layer 300 is more suitable for the space between the upper plate 100 and the lower plate 200.

[0038] Furthermore, the protrusion 210 is located at the top center of the lower plate 200, and the protrusion 210 is located in the rubber layer 300; there are a plurality of stoppers 120, which are located at intervals at the bottom of the upper plate 100, and the stoppers 120 are located outside the rubber layer 300.

[0039] In this embodiment, the lower plate 200, the protrusion 210 and the block 120 are respectively located inside and outside the rubber layer 300. During use, the block 120 and the protrusion 210 interact with each other through the rubber layer 300. The large side blower generates a lateral force due to rotation, part of which is borne by the force between the block 120 and the protrusion, thereby improving the rigidity between the upper plate 100, the lower plate 200 and the rubber layer 300 and improving the service life of the rubber layer 300.

[0040] Furthermore, the upper plate 100 has a first through hole 130 at the center, the protrusion 210 has a circular groove 211 on the side close to the upper plate 100, the rubber layer 300 has a second through hole 310, and also includes a limit block 400 arranged in the circular groove 211, the limit block 400 passes through the second through hole 310 and extends into the first through hole 130.

[0041] In this embodiment, the limit block 400 is in clearance with the circular groove 211, and the limit block 400 is connected to the lower plate 200 by a plurality of bolts. After the rubber layer 300 fails for some reason, the large side fan generates a lateral force due to rotation. Since the upper plate 100 and the large side fan are connected together, the large side fan will drive the upper plate 100 to move sideways, and the limit block 400 will abut against the first through hole 130, thereby preventing the upper plate 100 from moving sideways. The use of the limit block 400 can improve the protection performance of the shock absorbing device. After the rubber fails, the limit block 400 can temporarily limit the vibration and sideways movement of the large side fan.

[0042] Furthermore, the upper plate 100 has a plurality of first mounting holes 140 , the inner walls of the first mounting holes 140 have a shock absorbing layer 141 , and the lower plate 200 has a plurality of second mounting holes 220 .

[0043] In this embodiment, the first mounting hole 140 on the upper plate 100 can be fixed with a bayonet pin or bolt to the large side fan, and a shock-absorbing layer 141 made of nylon or fiber material can be used on the inner wall of the first mounting hole 140 to reduce the impact of the large side fan on the upper plate 100. The lower plate 200 is fixed to other objects by bolts passing through the second mounting holes 220, and threaded fasteners are added to the bolt holes of the lower plate 200 to improve the connection strength and reduce the impact of vibration on the connection between the lower plate 200 and other objects.

[0044] Furthermore, the first mounting hole 140 has a sliding groove 143 and a rotating groove 142 on one side away from the lower plate 200 , and the rotating groove 142 is located at the bottom of the sliding groove 143 , and also includes: a fixing pin 500 that is snap-fitted with the first mounting hole 140 .

[0045] In this embodiment, a fixing pin 500 is used to connect the upper plate 100 and the large side fan. The fixing pin 500 has a boss that matches the slide groove 143. The boss on the fixing pin 500 enters the rotating groove 142 through the slide groove 143. The fixing pin 500 can be fixed in the first mounting hole 140 by rotating the fixing pin 500. The fixing pin 500 uses a snap-on connection method that is more convenient for the installation and disassembly of the large side fan and the shock absorber assembly.

[0046] Furthermore, an elastic member 600 is disposed at the bottom of the first mounting hole 140 , and the elastic member 600 provides a force for the fixing pin 500 to leave the first mounting hole 140 .

[0047] In this embodiment, the elastic member 600 is arranged at the top of the first mounting hole 140. After the fixing pin 500 is inserted into the first mounting hole 140, the elastic member 600 is compressed. After the fixing member rotates, the boss enters the rotating groove 142. The boss is pressed against the rotating groove 142 at the bottom of the elastic member 600, thereby increasing the friction between the boss and the rotating groove 142 and reducing the influence of the vibration of the large side fan on the connection between the upper plate 100 and the large side fan.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
