Description

Technical Field

[0001] The present invention relates to the technical field of flexible brackets, and in particular to a tensioning flexible bracket. Background Art

[0002] The flexible support is a prestressed structural system whose main load-bearing components are cables, and a stable system is formed by stabilizing cables and struts.

[0003] After searching, the Chinese patent with announcement number CN108400750B is: A diagonal flexible photovoltaic support unit and photovoltaic support, including two oppositely arranged columns, a stabilizing cable and a plurality of main diagonal cables are arranged between the two columns, the upper ends of all the main diagonal cables of each group are connected to the upper part of the column at the corresponding end, the lower ends of the two groups of main diagonal cables are connected to the crossbeam, and the connection points are evenly arranged along the length direction of the crossbeam, and a plurality of suspension cables are arranged vertically and evenly between the crossbeam and the stabilizing cable. By adopting an optimized self-balancing prestressed cable system, the vertical stiffness of the structure is improved, and the vibration problem under wind load is solved, thereby significantly improving the spanning capacity of the photovoltaic support, further reducing the floor area, and having strong adaptability to areas with complex terrain. However, the above technical solution still has the following deficiencies when implemented:

[0004] (1) Poor stability of the columns: Since the columns support all the structures of the bracket, the force exerted on the photovoltaic panels will be transmitted to the columns in windy weather. The columns are simply fixed to the ground with rivets, which has poor stability. Once the force is too great, the columns will fall over;

[0005] (2) Poor bending buffering effect: The two columns are connected by a crossbeam. Since the crossbeam is a rigid structure, when the column is subjected to force and has a bending tendency, the crossbeam will block its bending and cannot buffer and offset the bending force;

[0006] (3) Inconvenient disassembly and assembly: The beam and the column need to be fixedly connected, usually by welding. When a column or beam is damaged and needs to be replaced, it needs to be cut by a machine and then re-welded after replacement, which is extremely inconvenient;

When installing the cross bar 4, the two ends of the cross bar 4 are pressed against the rubber blocks 808 and clamped in the mounting seat 801, so that the pin holes 807 on the outer surface of the cross bar 4 are correspondingly connected with the pin holes 807 on the outer surface of the mounting seat 801. Then, the two pin rods 803 are staggered and aligned with the pin holes 807 and inserted through them until the rubber sleeve 804 abuts against the side surfaces of the mounting seat 801, and then the two pin rods 803 are rotated so that the strip plates are clamped in the corresponding slots 806. Under the elastic force of the rubber sleeve 804, the cross bar 4 can be pressed against the side surfaces of the mounting seat 801 to achieve a locking effect.

Then the pin rods 803 can be pulled out to disassemble the cross bar 4, which has the effect of convenient disassembly and assembly of the cross bar 4.

[0043] The specific working principle of the present invention is as follows:

[0044] The flexible bracket of a tensioning method proposed by the present invention is composed of two columns and a cross bar 4, wherein the long column is composed of a bottom bar 1 and a main column 2, the short column is a secondary column 3, and the cross bar 4 is installed on the top of the two columns to form a bracket. When the bracket is installed, the bottom bar 1 is fixed to the ground with rivets, and then the main column 2 is fixed to the top of the bottom bar 1 with a connecting rod 501, and the ground lock 503 is moved to a suitable position so that the cable 502 is in a straight state. The ground lock 503 is fixed to the ground with rivets, and then the bolt rod 602 is screwed. The bolt rod 602 rotates and moves along the threaded sleeve 603. At the same time, the rotating bolt rod 602 will reel the cable 502, so that the cable 502 is tightened. The bolt rod 602 can be rotated in the opposite direction to loosen the cable 502. The bottom bar 1 is fixed by the cable 502 to increase the stability of the bottom bar 1. When encountering strong winds, the force on the column can be dispersed, thereby improving the overall wind resistance of the bracket.

[0045] A chuck is provided on the upper part of the outer surface of the main vertical rod 2 and the auxiliary vertical rod 3, and a single card lock 704 can be installed on the chuck, and a sliding rod 706 at the end of the single card lock 704 is inserted and arranged in the middle of the fan plate 701, and a steel spring 707 is sleeved on the part extending into the fan plate 701, and a double card lock 705 is installed on the outer surface of the fan plate 701, and the double card lock 705 is connected to the round rod 703 by a rotating member 702, so that the two ends of the round rod 703 can rotate and move, which is conducive to the application of brackets of different sizes. When the column is slightly bent in strong wind weather, the distance between the main vertical rod 2 and the auxiliary vertical rod 3 changes, which will push the sliding rod 706 to slide in the fan plate 701 and squeeze or stretch the steel spring 707, converting the bending force into the kinetic energy and internal energy of the spring, which has the effect of buffering and relieving the bending force, thereby improving the overall flexibility of the bracket and avoiding the situation where the column is overstressed and broken;

[0046] A mounting seat 801 is provided at the top end of the main vertical rod 2 and the auxiliary vertical rod 3. When installing the cross bar 4, the two ends of the cross bar 4 are pressed against the rubber block 808 and clamped in the mounting seat 801, so that the pin holes 807 on the outer surface of the cross bar 4 are correspondingly connected with the pin holes 807 on the outer surface of the mounting seat 801, and then the two pin rods 803 are staggered and aligned with the pin holes 807 and inserted through them until the rubber sleeve 804 abuts against the side of the mounting seat 801, and then the two pin rods 803 are rotated to make the strip plate clamped in the corresponding slot 806. Under the elastic force of the rubber sleeve 804, the cross bar 4 can be pressed against the side of the mounting seat 801 to achieve a locking effect. When disassembly is required, the pin rod 803 is squeezed and then the strip plate is rotated to make it slide out of the slot 806, and then the pin rod 803 is pulled out to disassemble the cross bar 4, which has the effect of convenient disassembly and assembly of the cross bar 4.
