[0038] Refer to the following Figures 1 to 6 The technical solutions of some embodiments of the utility model are described.

[0039] See attached Figure 1 and attached Figure 2 As shown, the technical solution adopted by the utility model is: to provide a column structure 100, including:

[0040] The column assembly includes a column outer tube 111 and a column inner tube 112, and one end of the column inner tube 112 is sleeved in the column outer tube 111;

[0041] A lifting assembly 120, the lifting assembly 120 is disposed on the column inner tube 112, and the lifting assembly 120 can lift the column outer tube 111;

[0042] The self-locking component includes at least one cam safety lock 131. The cam safety lock 131 is arranged on the column inner tube 112 and sleeved on one end of the column outer tube 111. When the lifting component 120 fails, the cam safety lock 131 can lock the column outer tube 111, so that the column outer tube 111 cannot be lifted or lowered.

[0043] Specifically, one end of the column inner tube 112 and the column outer tube 111 is set as the first end, and the other end of the column inner tube 112 is set as the second end. The lifting component 120 is fixedly connected to the second end of the column inner tube 112. The first end of the column inner tube 112 is provided with a plurality of fixed friction plates and sliding friction plates to reduce the friction during the lifting process. When the column outer tube 111 is lifted to the desired position, the column outer tube 111 and the column inner tube 112 are fixed by tightening bolts.

[0044] Specifically, the self-locking assembly includes two cam safety locks 131, which are movably connected to the first end of the column inner tube 112. The column inner tube 112 has two grooves. The cam safety lock 131 extends out of the column inner tube 112 through the grooves and abuts against the inner wall of the column outer tube 111. The protrusions of the two cam safety locks 131 abut symmetrically on the inner wall of the column outer tube 111. When the lifting assembly 120 fails, the cam safety lock 131 can lock the column outer tube 111 to prevent the column outer tube 111 from sliding down accidentally during installation.

[0045] See attached Figure 3 To Attachment Figure 5 As shown, in some embodiments, the self-locking assembly includes a hammer fixing seat 132, and the cam safety lock 131 is connected to the column inner tube 112 through the hammer fixing seat 132. The cam safety lock 131 abuts against the inner wall of the column outer tube 111. When the lifting assembly 120 fails, the cam safety lock 131 can be pressed by the column outer tube 111, so that the column outer tube 111 is locked and cannot move downward.

[0046] Specifically, the hammer fixing seat 132 is fixedly connected to the first end of the column inner tube 112, and the cam safety lock 131 is movably connected to the hammer fixing seat 132, and the cam safety lock 131 abuts against the inner wall of the column outer tube 111. When the lifting assembly 120 is working, the cam safety lock 131 is in an unlocked state and can rotate upward with the rise of the column outer tube 111. When the lifting assembly 120 has a problem and the column outer tube 111 slides downward, the friction between the column outer tube 111 and the cam safety lock 131 is greater than the gravity of the column outer tube 111, so the cam safety lock 131 prevents the column outer tube 111 from sliding downward.

[0047] As attached Figure 4 and attached Figure 5 As shown, specifically, the self-locking assembly includes two cam safety locks 131. When the lifting assembly 120 fails, the left cam safety lock 131 rotates counterclockwise, and the right cam safety lock 131 rotates clockwise. The gaps between the cam safety locks 131 on both sides and the inner walls of the column outer tube 111 become smaller and smaller until they are completely tightened. At this time, the cam safety locks 131 and the column outer tube 111 are in a locked state, and the column outer tube 111 will not slide downward, avoiding accidents during the installation process.

[0048] See attached Figure 3 and attached Figure 4As shown, in some embodiments, the self-locking assembly includes a safety rope 133, which passes through the interior of the column inner tube 112, one end of the safety rope 133 is connected to the cam safety lock 131, and the other end of the safety rope 133 is away from the cam safety lock 131, and the safety rope 133 passes through the column inner tube 112.

[0049] Specifically, one end of the safety rope 133 is connected to one end of the cam safety lock 131 away from the protrusion, and the other end of the safety rope 133 is arranged at the second end of the column inner tube 112 away from the cam safety lock 131, and the other end of the safety rope 133 extends out of the column inner tube 112. When the safety rope 133 is pulled, the cam safety lock 131 can be unlocked from the column outer tube 111, that is, the cam safety lock 131 can rotate in a direction away from the safety rope 133, and the cam safety lock 131 does not contact the inner wall of the column outer tube 111.

[0050] See attached Figure 3 and attached Figure 4 As shown, in some embodiments, the self-locking assembly also includes a rope pull ring 134, which is connected to one end of the safety rope 133 extending out of the column inner tube 112. When the rope pull ring 134 is pulled, the safety rope 133 can be pulled to prevent the cam safety lock 131 from contacting the inner wall of the column outer tube 111, thereby releasing the lock between the cam safety lock 131 and the column outer tube 111.

[0051] Specifically, the rope pull ring 134 is connected to one end of the safety rope 133 extending out of the column inner tube 112, which is convenient for pulling the rope pull ring 134, thereby pulling the safety rope 133, unlocking the cam safety lock 131 and the column outer tube 111, so that when parts need to be replaced or maintenance is required, the rope pull ring 134 can be pulled to unlock the cam safety lock 131 and lower the column outer tube 111, which is convenient for operation.

[0052] As attached Figure 4 and attached Figure 5 As shown, specifically, the safety rope 133 connects the two cam safety locks 131. When the rope pull ring 134 is pulled, the cam safety lock 131 on the left rotates clockwise, and the cam safety lock 131 on the right rotates counterclockwise. The cam safety locks 131 on both sides do not contact the inner wall of the column outer tube 111, thereby releasing the lock between the cam safety lock 131 and the column outer tube 111.

[0053] See attached Figure 5 As shown, in some embodiments, an elastic member 1311 is connected to the bottom end of the cam safety lock 131 near the safety rope 133 , and the elastic member 1311 is used to reset the cam safety lock 131 to lock the column outer tube 111 when the rope pull ring 134 is loosened.

[0054] Specifically, the elastic member 1311 can be configured as a spring, one end of the spring is connected to the bottom end of the cam safety lock 131 close to the safety rope 133, and the other end of the spring is connected to the fastener.

[0055] See attached Figure 3 and attached Figure 4 As shown, in some embodiments, a safety rope hook 135 is provided on the outer wall of the column inner tube 112 , and pulling the rope pull ring 134 to hang on the safety rope hook 135 can release the lock between the cam safety lock 131 and the column outer tube 111 .

[0056] Specifically, the rope pull ring 134 is pulled to hang on the safety rope hook 135, so that the cam safety lock 131 and the column outer tube 111 remain unlocked, and the column outer tube 111 can be raised and lowered at will, which is convenient for replacing parts and repairs.

[0057] See attached Figure 3 and attached Figure 4 As shown, in some embodiments, the self-locking assembly further includes a pulley member 136 , which is disposed inside the column inner tube 112 near the rope pull ring 134 , and the safety rope 133 passes through the pulley member 136 .

[0058] Specifically, the safety rope 133 passes through the pulley 136 to connect the cam safety lock 131 and the rope pull ring 134 respectively. The setting of the pulley 136 makes it easier to pull the rope pull ring 134, that is, unlocking the cam safety lock 131 and the column outer tube 111 is easier.

[0059] See attached Figure 4 As shown, in some embodiments, the lifting assembly 120 includes a pulley rope (not shown in the figure) and at least one fixed pulley, the fixed pulley is arranged inside the column inner tube 112, one end of the pulley rope is fixed to the bottom of the column outer tube 111, and the other end of the pulley rope passes through the fixed pulley for lifting the column outer tube 111.

[0060] Specifically, the lifting assembly 120 includes two fixed pulleys, namely a first pulley 1211 and a second pulley 1212. The first end and the second end of the column inner tube 112 are respectively provided with pulley mounting grooves. The first pulley 1211 is fixed to the pulley mounting groove of the first end of the inner tube column through a pulley fixing seat, and the second pulley 1212 is fixed to the position of the pulley mounting groove at the second end of the column inner tube 112 through a pulley fixing seat. One end of the pulley rope is fixed to the bottom of the column outer tube 111, and passes through the first pulley 1211 and the second pulley 1212 to lift the column outer tube 111. The arrangement of the pulley rope and the fixed pulley 121 makes lifting the column outer tube 111 more time-saving and labor-saving.

[0061] See attached Figure 1 To Attachment Figure 4As shown, in some embodiments, the lifting assembly 120 also includes a manual winch 122 and a winch base 123. The manual winch 122 is arranged at one end of the column inner tube 112 away from the cam safety lock 131. The manual winch 122 is fixed to the outer wall of the column inner tube 112 through the winch base 123. The manual lifting of the column outer tube 111 is achieved by rotating the handle of the manual winch 122 to drive the pulley rope.

[0062] Specifically, the manual winch 122 is arranged on a side of the column inner tube 112 near the second pulley 1212, and the manual winch 122 is fixedly connected to the column inner tube 112 through the winch base 123, and the other end of the pulley rope is connected to the manual winch 122. Optionally, a chassis reinforcement rib can be arranged between the winch base 123 and the column inner tube 112. The handle of the manual winch 122 is turned so that the pulley rope drives the column outer tube 111 to rise or fall, and the installation process saves a special crane and an aerial work vehicle, greatly reducing the installation cost.

[0063] See attached Figure 6 As shown, the utility model also provides a photovoltaic bracket, which includes a photovoltaic panel mounting structure 300, a main beam frame structure 200 and a column structure 100 of any one of the above embodiments, the column structure 100 is connected to the photovoltaic panel mounting structure 300 through the main beam frame structure 200, and the installation of the photovoltaic bracket is completed by lifting the column structure 100 through the lifting assembly 120.

[0064] Specifically, the photovoltaic support installation process can be to first install the column structure 100, then connect the main beam frame structure 200 with the column structure 100, connect the photovoltaic panel installation structure 300 with the main beam frame structure 200, rotate the manual winch 122 on the outer wall of the column inner tube 112, raise the column outer tube 111 to the required height, and then lock the column outer tube 111 and the column inner tube 112 by tightening the bolts. The installation process does not require a crane or an aerial work machine, which saves time and effort and reduces installation costs. In addition, the column structure 100 of the photovoltaic support has a self-locking function. When the lifting component 120 fails, it can lock the column outer tube 111 to prevent it from sliding down, thereby preventing danger during the installation process.

[0065] The above description is intended to be illustrative rather than restrictive, and those skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of them) may be used in combination with each other, and it is contemplated that these embodiments may be combined with each other in various combinations or permutations.
