Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a rolling connection structure between a middle column and a main cable. Background Art

[0002] Flexible photovoltaic brackets are widely used in mountain photovoltaics due to their good flexibility and large span. The columns are connected by cables.

[0003] In the past, in order to achieve the connection between the cable and the steel column, the connection was made through the form of anchors, which resulted in mutual deformation between the cables and adjacent cables, which had an adverse effect on the steel column supporting it.

[0004] In order to avoid the influence of adjacent cables on steel columns, the prior art uses round steel or rollers to connect them. However, after the cables are tensioned, they still have an impact on the stress of the steel columns, making it difficult to meet the design assumptions, and affecting the stability and safety of the structure to a certain extent.

[0005] For this reason, we urgently need to provide a rolling connection structure between a middle column and a main cable. Utility Model Content

[0006] The purpose of the utility model is to provide a rolling connection structure between a middle column and a main cable, so as to solve the problem in the above-mentioned background technology that after the cable is tensioned, the force on the steel column is still affected, it is difficult to meet the design assumptions, and the structural stability and safety are affected to a certain extent.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rolling connection structure between a middle column and a main cable, comprising a base plate and a bracket, wherein the bracket is fixedly installed on the left and right sides of the top of the base plate, and a connecting device is arranged above the base plate, wherein the connecting device comprises a connecting unit and a clamping unit.

[0008] The connecting unit is arranged below the left and right brackets, and the pressing unit is arranged between the left and right brackets and located at the upper end of the connecting unit.

[0009] The connection unit includes a bolt 1, a nut 1 and a pulley, wherein the bolt 1 passes through the lower ends of the left and right brackets, the nut 1 is threadedly connected to the right outer surface of the bolt 1, and the pulley is rotatably connected to the outer surface of the bolt 1 and is located between the left and right brackets.

[0010] The clamping unit includes bolt 2, nut 2 and a roller. The bolt 2 passes through the upper ends of the left and right brackets. The nut 2 is threadedly connected to the right outer surface of the bolt 2. The roller is rotatably connected to the outer surface of the bolt 2 and is located between the left and right brackets.

[0011] Preferably, the outer surface of bolt one is located on the right side of nut one and the outer surface of bolt two is located on the right side of nut two and is threadedly connected with nut three, and nut one and nut two are prevented from loosening by nut three to avoid relative rotation between the bolt and the nut, which causes the nut and the bolt to loosen and separate.

[0012] Preferably, the tightening force of the two nuts three is respectively greater than the tightening force of nut two and nut one, thereby improving the anti-loosening effect of nut two and bolt two and nut one and nut one.

[0013] Preferably, a gasket is installed on the left outer surface of the bolt 2 and the bolt 1, and the gasket is made of rubber material to prevent the bolt 2 and the bolt 1 from rubbing against the side wall of the bracket and causing damage to the bracket surface.

[0014] Preferably, the pulley is U-shaped.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The rolling connection structure between the middle column and the main cable utilizes the advantages of the pulley, which can easily change the direction of the cable on irregular mountains and provide tension to each other during the tensioning process, thus achieving an overall balanced relationship. Compared with the traditional connection relying on various anchors, it is more reasonable and reliable, easy to process and manufacture, and has a simple force transmission path. It solves the problem raised in the background technology that the cable still affects the force on the steel column after being tensioned, making it difficult to meet the design assumptions and affecting the stability and safety of the structure to a certain extent.

[0017] 2. The rolling connection structure between the middle column and the main cable can meet the force at the connection position by setting a connection device. There is no eccentric force problem and the force is balanced. At the same time, the main cable can effectively unload some forces in other directions through the pulley at the column head, so that the axial force of the cable coincides with the centroid of the cable, making the force more reasonable.
