Description
Technical field
The utility model belongs to large scale electrical power unit Terrace prevention technical field under outdoor environment, more particularly to a kind of windproof
Punch ball head protection set.
Background technology
In large scale electrical power unit platform system, Universal spherical steel support is used so that when the node structural component is held
When being acted on by the external force (most typically wind and geological process) of nature all directions, which can be in all directions freedom
Rotation release moment of flexure.However power equipment platform is in more remote area mostly, the impact of long-term dust storm can be caused to bulb
Abrasion, corrode so that rotary resistance between bulb and ball-and-socket increase reduces the service life of bulb, whole equipment is put down
The long-term safety operation of platform hides some dangers for.Based on considerations above, the present inventor is studied for existing spherical hinge structure, this case
Thus it generates.
Utility model content
The purpose of this utility model is to provide a kind of bulb sand-proof protective case, and can effectively protect bulb is exempted from
By long-term impact, the erosion of dust storm, and the power equipment that flexural pivot is simply housed suitable for different types of support system is installed
Platform.
In order to achieve the above objectives, the solution of the utility model is：
A kind of bulb sand-proof protective case, including upper annulus and lower annulus, wherein, the section of upper annulus is with a narrow upper and lower width
Trapezoidal, the upper annulus is bonded with the surface interference of upper bracket boss, at the height of upper annulus and upper bracket boss arc transition
It is flush；In up-narrow and down-wide trapezoidal, the surface of undersetting boss is withstood in the bottom of the lower annulus in the section of lower annulus.
The both sides of above-mentioned lower annulus also offer venthole respectively.
The bottom end of above-mentioned lower annulus is not contacted with undersetting disc surfaces.
The surface of the transition position and upper bracket boss of above-mentioned upper and lower annulus fits.
Above-mentioned sand-proof protective case is made of methyl ethylene silica gel material.
After using the above scheme, the beneficial effects of the utility model are：
(1) protective case of the utility model and the compactness of upper undersetting are high, have higher wearability and corrosion resistance,
It can prevent bulb from being impacted, while dust storm, bulky grain sand and dust and erosion is avoided to enter bulb contact gap by outdoor big dust storm,
Greatly improve the service life of bulb.
(2) protective case of the utility model does not influence the normal mounting of bearing platform, and not easily to fall off in normal operation,
It avoids impacting the dismounting of platform.
(3) protective case provided by the utility model can be suitable for a plurality of types of large scale electrical power unit platforms, installation letter
It is single, it is easy to use.
The utility model discloses a kind of bulb sand-proof protective case, which is in using methyl ethylene silica gel as material
One cross sectional shape is the annulus of bending-type, wherein upper annulus is expanded outwardly and is bonded with upper bracket boss surface interference, highly with
It is flushed at upper bracket arc transition, lower annulus extends out that amplitude is smaller, and only undersetting boss surface, upper and lower ends mouth are withstood in its bottom
Bending part be bonded with upper bracket boss surface, respectively there are one small air holes to enhance protective case and bearing for band for lower annulus both sides
Compactness.The protective case of the utility model has higher wearability and corrosion resistance, and installation is simple, easy to use, can prevent
Bulb is impacted by outdoor big dust storm, greatly improves the service life of bulb.

Fig. 1 is the complete section structure diagram of the utility model；
Fig. 2 is bulb sand-proof protective case and bulb bearing half section structure diagram；
Fig. 3 is bulb sand-proof protective case and bulb bearing cooperation schematic diagram.
Specific embodiment
Below with reference to attached drawing, the technical solution of the utility model and advantageous effect are described in detail.
As shown in Figure 1 to Figure 3, the utility model provides a kind of bulb sand-proof protective case, including upper annulus 1 and lower annulus
2, wherein, the section of upper annulus 1 is with a narrow upper and lower width trapezoidal, and the section of lower annulus 2 is in up-narrow and down-wide trapezoidal so that protective case
Whole is in the annulus that a cross sectional shape is bending-type.The upper annulus 1 expand outwardly and with the surface interference of upper bracket boss 6
Fitting, the height of upper annulus 1 is advisable with being flush at upper bracket boss arc transition 5, so that upper bracket boss circular arc
Transition position 5 can be held out against protective case downwards using its structure feature；It is smaller that the lower annulus 2 extends out amplitude, and only its bottom is pushed up
It stays the surface of bearing boss 7.
In the present embodiment, the both sides of the lower annulus 2 also offer venthole 3 respectively so that protective case internal clearance is empty
Gas is communicated with outside, keeps the gas permeability in outside in protective case, prevents bulb from reducing guarantor due to internal and external pressure difference in rotation
The compactness of sheath and bearing.
Bolt hole is evenly equipped on bulb upper bracket disk 4 and undersetting disk 9, if come off may be to bearing for protective case
Dismounting impacts, since upper bracket boss 6 and 7 surface of undersetting boss can utilize undersetting boss to justify with protective case fitting
The circular arc feature of arc transition position 8 withstands protective case upwards so that and the bottom end of lower annulus 2 is not contacted with 9 surface of undersetting disk,
So as to not interfere with the dismounting of bearing.
The sand-proof protective case is made of methyl ethylene silica gel material, high- and low-temperature resistance, moisture-proof, electrical insulating property,
Ageing-resistant, surface non-stick and hydrophobicity, compressive deformation is small, can play the protective action to bulb long-term effectively.
When the utility model is installed, need that first protective case is sleeved on undersetting boss 7, upper ball-and-socket is then wrapped into lower ball
First 10,6 surface of upper bracket boss is bonded with 1 interference of upper annulus of protective case, the bending part that upper annulus 1 is connected with lower annulus 2
It is bonded with 6 surface of upper bracket boss, and 5 held out against protective case downwards using its structure feature at upper bracket boss arc transition.
The bulb protective case of this structure can be suitable for a plurality of types of large scale electrical power unit platforms, and installation is simple, easy to use.
Above example is only to illustrate the technological thought of the utility model, it is impossible to the protection model of the utility model is limited with this
Enclose, it is every according to the utility model proposes technological thought, any change done on the basis of technical solution each falls within this reality
Within the scope of novel protected.
