Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a synchronous shaft suspension support structure for multi-point mechanical linkage of photovoltaic supports. Background Technology

[0002] When installing a photovoltaic tracking bracket, the photovoltaic panels are typically driven to rotate using a combination of a main beam and a synchronous shaft. The synchronous shaft is usually fixed to the bottom or side of the main beam using a single support component or a single suspension component. The positions of the synchronous shaft and the main beam are roughly parallel and relatively fixed. During the actual operation of the tracking bracket, the rotation speed and direction of the main beam and the synchronous shaft are usually not completely consistent. Therefore, to some extent, the synchronous shaft will not be completely parallel to the main beam. This not only affects the aesthetics, but also, because the two are not moving in the same straight line for a long time, it is very easy to cause fatigue fracture of the synchronous shaft and reduce its service life.

[0003] In view of this, the person in charge of the utility model in this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a synchronous shaft suspension support structure for multi-point mechanical linkage of photovoltaic brackets. When the main shaft rotates, it will not affect the axial position of the synchronous shaft, and the rotation of the two shafts will not affect each other. At the same time, the connecting structure can also support the synchronous shaft, effectively reducing the deflection deformation of the synchronous shaft.

[0005] The solution adopted by this utility model to solve the technical problem is: a synchronous shaft suspension support structure for multi-point mechanical linkage of photovoltaic brackets, used to suspend and fix the synchronous shaft on the main bearing beam, including a bracket, a clamp, a sliding rod and a bearing assembly. The clamp is tightly installed on the main bearing beam with the bracket. The bracket is provided with an arc-shaped sliding groove. One side of the sliding rod is slidably installed in the arc-shaped sliding groove. The bearing assembly is installed on the other side of the sliding rod so that it can be slidably installed on the bracket through the sliding rod.

[0006] Furthermore, in order to form a guide sliding structure between the main shaft and the synchronous shaft, the upper side of the bracket is provided with a U-shaped groove along the circumference of the bracket to form an arc-shaped sliding groove. The bracket is also provided with a through groove that runs vertically through the U-shaped groove and has a groove diameter smaller than the U-shaped groove diameter so that the sliding rod can be slidably installed on the arc-shaped sliding groove.

[0007] Furthermore, in order to slide the sliding rod in the arc-shaped groove, one end of the sliding rod is provided with a cylindrical head, the axis of which is perpendicular to the length direction of the sliding rod, and the cylindrical head slides in the U-shaped groove after passing through the through groove.

[0008] Furthermore, in order to detachably install the sliding rod in the arc-shaped groove, the diameter of the cylindrical head is slightly smaller than the groove diameter of the through groove so that the cylindrical head can pass parallel through the through groove and be inserted into the U-shaped groove. The length of the cylindrical head is greater than the groove diameter of the through groove to prevent the cylindrical head from coming out of the arc-shaped groove, and the length of the cylindrical head is less than the groove diameter of the U-shaped groove so that the cylindrical head can be inserted into the U-shaped groove.

[0009] Furthermore, in order to install the bearing on the main bearing beam via the connector, the main bearing beam is an octagonal tube with several planes and several inclined surfaces. The clamp has an upper horizontal surface and an upper inclined surface that conform to the contour of the main bearing beam. The bracket has a lower horizontal surface and a lower inclined surface that conform to the contour of the main bearing beam. The upper and lower inclined surfaces are completely fitted with the inclined surfaces of the main bearing beam to tighten the clamp and bracket onto the main bearing beam. There is a gap of at least 1 mm between the upper and lower horizontal surfaces and the plane of the main bearing beam to avoid over-constraining the installation of the main bearing beam.

[0010] Furthermore, in order to limit the bearing assembly to be mounted on the sliding rod, a bearing sleeve for mounting the bearing assembly is provided on the other side of the sliding rod. The bearing assembly includes a bearing and a bearing shoulder. The bearing includes a rotating body mounted in the bearing sleeve and an annular flange located on one side of the rotating body. The diameter of the annular flange is larger than the inner diameter of the bearing sleeve so as to limit the fit with one end face of the bearing sleeve. The bearing shoulder is detachably mounted on the side of the rotating body opposite to the annular flange. The bearing shoulder is provided with a flange protrusion for locking onto the other end face of the bearing sleeve so as to fit with the annular flange and limit the bearing assembly to be mounted in the bearing sleeve.

[0011] Furthermore, in order to form a synchronous shaft mounting structure, the rotating body is provided with a square hole for mounting the synchronous shaft, and the outer diameter of the rotating body is adapted to the inner diameter of the bearing sleeve.

[0012] Furthermore, in order to install the bearing shoulder on the bearing, the bearing shoulder includes a body and a snap-fit ​​portion extending downward from one end of the body, the flange protrusion is formed by extending downward from the other end of the body, the rotating body is provided with a groove for installing the body, the height of the groove is adapted to the height of the body, and the rotating body is also provided with a slot located inside the groove for snapping into the snap-fit ​​portion to install the bearing shoulder on the bearing.

[0013] Furthermore, in order to securely install the bracket and clamp onto the main bearing beam, both the bracket and clamp are semi-circular to form a clamping hole for installing the main bearing beam. The two ends of the clamp are fixedly connected to the two ends of the bracket by bolts and nuts, respectively, thereby securing the clamp and bracket onto the main bearing beam.

[0014] Furthermore, in order to connect the bracket and the clamp, the clamp is provided with lugs at both ends, and the lugs are provided with round holes for installing bolts. The bracket is provided with corresponding lugs at both ends, and the lugs are provided with slot holes for installing bolts.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The bracket of this utility model is hollow molded with ultra-high molecular weight polyethylene material. The inside is provided with an arc-shaped groove as a channel for the rotation and sliding of the tracking bracket. The clamp is formed by carbon steel stamping and fixed to the main bearing beam. The inside of the arc-shaped groove of the bracket is closely matched with the outer surface of the sliding rod. The sliding rod material is ADC12. The low friction coefficient between the sliding rod and the ultra-high molecular weight polyethylene material of the bracket achieves self-lubrication. The synchronous shaft is installed in the bearing sleeve through plastic bearing and plastic bearing shoulder. During installation, the sliding rod is inserted into the arc-shaped groove from bottom to top and then rotated 90° to lock, so that the sliding rod and the bracket slide together.

[0017] (2) The bracket of this utility model is integrally injection molded from ultra-high molecular weight polyethylene material. The two lower inclined surfaces are tightly fitted with the main bearing beam, and the lower horizontal surface retains a 1mm gap with the main bearing beam. The clamp is integrally formed by stamping, and the upper horizontal surface retains a 1mm gap with the main bearing beam. The clamp and bracket are tightly installed with the main bearing beam through the complete fit between the inclined surfaces. By forming a gap between the planes, the over-constraint phenomenon caused by the competition between the inclined surfaces and the planes when they are both fitted is effectively avoided.

[0018] (3) The bracket of this utility model has been locally thickened and strengthened at the connection between the lugs on both sides and the bolts to improve the overall strength. The bolt mounting holes on the lugs are adjustable strip holes perpendicular to the axial direction of the main bearing beam. The clamp is formed by stamping. The bolt mounting surface of the clamp lug and the side are punched with small protrusions in a 45° shape to enhance the bending resistance of the part. The bolt mounting holes of the clamp lugs are round holes.

[0019] (4) The sliding rod of this utility model adopts aluminum die casting molding process. The sliding rod is shaped like "T" and has a sliding function. The bearing sleeve is shaped like "O". The bearing sleeve is installed with a bearing and a bearing shoulder. The bearing is integrally injection molded from ultra-high molecular weight polyethylene material. One side has an annular flange and the other side has a concave groove. The bearing shoulder is integrally injection molded from ultra-high molecular weight polyethylene material. One side has a flange protrusion and the other side has a snap-fit ​​part. It is installed with the bearing to form a complete bearing assembly. Attached Figure Description
