The bearing support plate 16 and the lower pulley guide plate 17 both extend along the extension direction of the profile body 11. The bearing support plate 16 is used for supporting the bearing wheel 22, and the lower pulley guide plate 17 is used for providing a supporting force for the pulley and guiding the pulley to move along the extending direction of the profile main body 11.
The cross section of the lower pulley guide plate 17 is wholly shaped like L, and the lower pulley guide plate 17 and the profile main body 11 are semi-enclosed to form a lower pulley installation groove 18 with a downward opening.
The profile body 11 is fixedly connected with an upper pulley guide plate 19 located above the load bearing support plate 16.
The section bar main body 11 is provided with a light-weight through groove 15, and the extending direction of the light-weight through groove 15 is parallel to the extending direction of the section bar main body 11.
The thickness of the bearing support plate 16 is greater than the thickness of the lower sheave guide plate 17.
The moving mechanism 21 installed on the profile body comprises a bearing wheel 22, an upper sliding wheel 23, a lower sliding wheel 24 and a carbon brush connecting end 25, wherein the bearing wheel 22, the upper sliding wheel 23 and the lower sliding wheel 24 are respectively abutted with the bearing support plate 16, the upper sliding wheel guide plate 19 and the lower sliding wheel guide plate 17. A gear belt 27 is installed in the synchronous belt installation groove 12, the moving mechanism 21 is rotatably connected with a power gear 28 meshed with the gear belt 27, a motor with an output shaft fixedly connected with the power gear 28 is arranged in the moving mechanism 21, the motor is used for driving the power gear 28 to rotate, and the moving mechanism 21 is driven to move through the transmission of the power gear 28 and the gear belt 27. And a carbon brush sliding contact wire 26 clamped with the carbon brush clamping plate 13 is arranged in the carbon brush sliding contact wire groove 14, the carbon brush connecting end 25 is in sliding connection with the carbon brush sliding contact wire 26, and the control and power supply of the motor are realized through the carbon brush sliding contact wire 26 and the carbon brush connecting end 25.
Compared with the prior art, the beneficial effects of the utility model are that:
most of the gravity of the moving mechanism 21 is offset by the supporting force provided by the bearing wheel 22, so that the friction force at the bearing wheel 22 is large. When the power gear 28 drives the moving mechanism 21 to move, the power gear 28 generates a torque above the moving mechanism 21, so that the moving mechanism 21 tends to rotate around the bearing wheel 22, and the upper and lower runners 23 and 24 are engaged with the profile body 11, so as to prevent the moving mechanism 21 from rotating further, but at this time, the hanging assembly 29 connected to the moving mechanism 21 has generated a large shake. The bearing support plate 16 is arranged above the lower pulley guide plate 17 and the carbon brush sliding contact wire groove 14, so that the distance between the bearing support plate 16 and the bearing wheel 22 and the power gear 28 is shortened, the torque applied on the moving mechanism 21 by the power gear 28 can be effectively reduced, the rotation and the inclination of the moving mechanism 21 in the operation process are restrained, and the effects of reducing the moving mechanism 21 and hanging the component 29 to shake are achieved.
Due to the wobbling of the moving mechanism 21 and the friction of the upper and lower runners 23, 24 with the profile body 11, a loud noise is generated. The noise generated by the shaking can be suppressed by suppressing the shaking of the moving mechanism 21 and the hanging assembly 29, thereby achieving the noise reduction effect.
When the moving mechanism 21 shakes, the connection between the carbon brush connection end 25 and the carbon brush sliding contact wire 26 is affected, and the communication stability between the carbon brush connection end 25 and the carbon brush sliding contact wire 26 is affected, so that the running accuracy of the motor is affected. The communication between the carbon brush connecting end 25 and the carbon brush sliding contact wire 26 can be more stable while the shaking of the moving mechanism 21 and the hanging component 29 is restrained, so that the effect of improving the running precision of the motor is achieved.
The bearing support plate 16 and the lower pulley guide plate 17 support the bearing wheel 22 and the lower pulley 24 respectively, so that the stress on the bearing support plate 16 and the lower pulley guide plate 17 is not interfered with each other, the bearing support plate 16 and the lower pulley guide plate 17 are prevented from being deformed and broken by the pressure of the bearing wheel 22 and the lower pulley 24 at the same time, the structural stability is improved, and the effect of inhibiting shaking can be achieved.
Two carbon brush cardboard 13 adjacent with bearing support plate 16 and lower pulley guide 17 are respectively with bearing support plate 16 and lower pulley guide 17 fixed connection to support each other with bearing support plate 16 and lower pulley guide 17 respectively through two carbon brush cardboard 13, improve bearing support plate 16, lower pulley guide 17 and carbon brush cardboard 13's structural stability, make this wall track section bar more firm.
Through the relative position structure of bearing backup pad 16, lower pulley guide board 17 and carbon brush sliding contact wire casing 14 on the section bar body, realized simultaneously that the intensity of rocking is less, the running noise is less and the higher advantage of motor precision to, should cut off track section bar simple structure, the production of being convenient for, also have better structural stability, overall structure is more firm, has longer life.
When the power gear 28 rotates and exerts a torque on the moving mechanism 21, the lower pulley 24 has a tendency to deflect obliquely upward. The opening of the lower sheave mounting groove 18 is directed downward, and when the lower sheave 24 is mounted in the lower sheave mounting groove 18, the lower sheave 24 can be blocked by the lower sheave guide plate 17, and the lower sheave 24 is prevented from moving upward, thereby suppressing the movement of the moving mechanism 21.
The upper sheave 23 guide plate provides the upper sheave 23 with a supporting force, and the stability of the moving mechanism 21 can be improved.
Through the setting of groove 15 is led to in the lightweight, when reducing the whole weight of section bar body, can also play save material's effect, reach reduce cost's effect.
Since most of the pressure of the moving mechanism 21 is applied to the bearing support plate 16 through the bearing wheel 22, the structural strength of the bearing support plate 16 is ensured by setting the thickness of the bearing support plate 16 to be large. Thickness through setting up lower pulley guide board 17 is less, when can playing the whole weight that reduces the section bar body, can also play save material's effect, reaches reduce cost's effect.
In conclusion, after the ordinary skilled in the art reads the document of the present invention, according to the present invention, the technical solution and technical concept of the present invention do not need creative mental labor to make other various corresponding transformation schemes, which all belong to the protection scope of the present invention.
