[0052] A plurality of positioning units 5 are arranged on the mounting beam 2 and are used to position the mounting position and the mounting angle of the supporting unit 4;

[0053] During actual operation, the position of the positioning unit 5 can be installed as needed according to the construction drawings, and then the support unit 4 can be installed on the positioning unit 5 according to the positioning unit 5, so that the cantilever beam 3 can be lifted to the position of the support unit 4 through the support unit 4 and the lifting equipment, and then installed on the mounting beam 2, and the cantilever end of the cantilever beam 3 can be supported after installation.

[0054] Wherein, the positioning unit 5 comprises:

[0055] A positioning column 51 is fixedly disposed on the mounting beam 2;

[0056] A positioning seat 52 is inserted on the positioning column 51 through a positioning hole 53 and is mounted on the mounting beam 2. The support unit 4 is arranged on the positioning seat 52;

[0057] An angle adjustment portion 54 is disposed between the positioning column 51 and the positioning seat 52 and is used to adjust the angle of the positioning seat 52;

[0058] In actual use, the positioning angle can be adjusted to the installation angle of the cantilever beam 3 through the angle adjustment part 54, so that when the cantilever beam 3 is installed, it can be installed on the installation beam 2 by cooperating with the support unit 4 to achieve adaptive angle adjustment.

[0062] When the actual angle of the positioning seat 52 is adjusted, the positioning seat 52 is first adjusted to the installation angle of the cantilever beam 3, and then the positioning seat 52 is inserted into the positioning column 51 through the positioning hole 53. At the same time, the spline 541 and the keyway 542 will be engaged, thereby achieving the engagement of the positioning column 51 and the positioning seat 52.

[0063] Meanwhile, the support unit 4 comprises:

[0064] The installation auxiliary part 41 is arranged on the positioning seat 52, and is used to assist the cantilever beam 3 and the mounting beam 2 to dock when the lifting equipment lifts the cantilever beam 3 to a position near the mounting beam 2;

[0065] The support assembly is arranged between the support seat and the cantilever beam 3 and the mounting beam 2 , and is used for supporting the cantilever beam 3 .

[0066] Wherein, the support assembly comprises:

[0067] The first support portion is disposed between the mounting beam 2 and the cantilever beam 3, and with the assistance of the mounting auxiliary portion 41, the mounting connection between one end of the cantilever beam 3 and the mounting beam 2 is achieved;

[0068] The second support portion 43 is arranged between the support seat and the other end of the cantilever beam 3, and is used to support the cantilever end of the cantilever beam 3. The cantilever beam 3 is provided with two groups of symmetrically arranged lifting ears 31 for cooperating with lifting equipment for lifting and cooperating with the second support portion 43 for support.

[0069] Meanwhile, the first supporting part comprises:

[0070] An anchor hole 421 is provided on the cantilever beam 3;

[0071] An anchor rod 422, arranged on the mounting beam 2, to be inserted into the anchor hole 421;

At the same time, after the anchor rod 422 and the anchor hole 421 are completely docked, the locking of one end of the cantilever beam 3 can be achieved through the installation auxiliary part.

[0073] In addition, the second supporting portion 43 includes:

[0074] A first supporting arm 431, one end of which is rotatably disposed on the positioning seat 52, and the other end of which is provided with a second supporting arm 433;

[0075] A threaded rod 432 is disposed between the first support arm 431 and the second support arm 433 and is threadedly connected to the first support arm 431 and the second support arm 433. A knob 434 for rotating the threaded rod 432 is disposed on the threaded rod 432.

[0076] A connecting plate 435 is fixedly disposed at one end of the second supporting arm 433 away from the first supporting arm 431;

[0077] The clamping members are symmetrically arranged on both sides of the connecting plate 435 and are used to elastically clamp the lifting ears 31 on the cantilever beam 3 .

[0078] At the same time, the clamping member comprises:

[0079] At least two groups of sliding rods 436 are fixedly disposed on both sides of the connecting plate 435, and a limiting plate is disposed at one end of the sliding rod 436 away from the connecting plate 435;

[0080] The clamping plate 437 is slidably disposed on the sliding rod 436 between the limiting plate and the connecting plate 435;

[0082] A fixing column 439 is disposed at one end of the clamping plate 437 away from the connecting plate 435 and is used to be clamped into the lifting ear 31;

[0083] After one end of the cantilever beam 3 is initially fixed by the first supporting portion, the threaded rod 432 is then rotated by means of the knob 434 to adjust the total length between the first supporting arm 431 and the second supporting arm 433 until the fixing column 439 can just fit into the hanging ear 31, and then the clamping plate 437 is pulled to both sides so that the fixing column 439 can be rotated to the ear hole position of the hanging ear 31, and then the clamping plate 437 is released. Under the action of the clamping spring 438, the clamping plate 437 can be clamped so that the fixing column 439 fits into the ear hole of the hanging ear 31, so that the second supporting portion 43, the positioning seat 52 and the cantilever beam 3 form a triangular supporting structure as a whole, thereby improving the overall stability of the cantilevered portion of the cantilever beam 3, thereby preventing the cantilever beam 3 from deforming and sagging due to its own weight and the steel structure roof it carries under long-term stress, resulting in structural deformation.

[0084] Finally, the installation auxiliary part 41 includes:

[0085] Two groups of L-shaped plates 411 are symmetrically and fixedly arranged on both sides of the positioning seat 52;

[0086] Two groups of guide blocks are respectively arranged on the sides of the two groups of L-shaped plates 411 close to each other, and the guide blocks include a long strip portion 412 and a guide portion 413, and the guide portion 413 is in the shape of an inclined boss;

[0087] The elastic protrusion 414 is arranged on the long strip portion 412 of the guide block, and the cantilever beam 3 is provided with a fixing groove used in cooperation with the elastic protrusion 414;

[0088] When an I-shaped channel steel is used for the cantilever beam 3, the width of the guide block is consistent with the width of the inner recess of the I-shaped channel steel. When the lifting equipment lifts the cantilever beam 3 to near the guide portion 413, when it continues to approach the mounting beam 2, it will pass through the limit of the guide portion 413, and will slowly approach the long strip portion 412, and slide to near the mounting beam 2. Since the angle of the positioning seat 52 has been adjusted and installed, the angle of the sliding cantilever beam 3 will also be adjusted at this time. At the same time, during the sliding process of the long strip portion 412, the anchor rods 422 and the anchor rods 422 will dock with each other. At the same time, when the cantilever beam 3 is attached to the mounting beam 2, it will be fixed by the elastic protrusion 414 and the fixing groove. After the support unit 4 completes the installation of the cantilever beam 3, the upper end of its positioning column 51 will be set to a threaded shape, and the positioning seat 52 can be fixed by bolts.
