Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] A fast installation node mechanism for super-high all-steel structures, see Figures 1 to 6 , including a main component 300, a mounting component 100, and an auxiliary component 200.

[0039] The auxiliary component 200 includes two fixing plates 210 installed at both ends of the auxiliary component 320. The bottom surface of the fixing plate 210 is located below the bottom surface of the auxiliary component 320 and an operating gap is reserved between the two. The top surface of any one of the fixing plates 210 is connected to the auxiliary component 320 by two support rods 240.

[0040] The locking member 114 has a first inclined surface 117 at one end close to the auxiliary member 320 , and the locking cylinder 130 has a second inclined surface 132 at one end close to the main member 310 . The first inclined surface 117 and the second inclined surface 132 are engaged with each other.

[0041] A spring 116 is installed at one end of any one of the locking members 114 close to the inner wall of the first mounting groove 340, and any one of the springs 116 is connected to the inner wall of the first mounting groove 340; a second thread groove 390 is provided at one end of the first mounting groove 340 close to the auxiliary member 320, and the first thread groove 131 and the second thread groove 390 are embedded with each other. Four symmetrical mounting holes 360 are provided on the main member 310, and four brackets 330 are installed at the bottom of the auxiliary member 320. The bracket 330 is a conical structure with a small bottom and a large top. The diameter of any one of the mounting holes 360 is equal to the outer diameter of the corresponding bracket 330.

[0042] Four second threaded holes 370 are symmetrically provided on the main part 310, and two first through holes 230 are provided on any one of the fixing plates 210. The first through holes 230 and the second threaded holes 370 have equal diameters. Two bolts 220 are connected to the fixing plate 210, and any one of the bolts 220 is engaged with any one of the first through holes 230 and the second threaded holes 370.

[0043] During operation, the auxiliary component 320 is directly moved to the top of the main component 310, and then the fixing column 120 at the lower end of the auxiliary component 320 is inserted from the first mounting groove 340 until it contacts the bottom end of the second mounting groove 350, and then the locking cylinder 130 is inserted into the area between the fixing column 120 and the first mounting groove 340, and the first thread groove 131 and the second thread groove 390 on the locking cylinder 130 are engaged, and then the force rod 133 is grasped to drive the locking cylinder 130 to rotate clockwise. When the locking cylinder 130 rotates in the first mounting groove 340, It will gradually move downward, and the second inclined surface 132 at the bottom of the locking cylinder 130 and the first inclined surface 117 of the locking piece 114 will be completely fitted. The random locking piece 114 will be constrained by the locking cylinder 130 and gradually closed inward, and then the top of the locking piece 114 will enter the slot 121 opened on the fixing column 120. When the auxiliary component 320 is vibrated, it will drive the fixing column 120 installed at the lower end to move upward. At this time, the block 115 installed on the inner wall of the locking piece 114 will firmly fix the fixing column 120 to prevent it from falling off.

[0044] When it is found that the installation is different and needs to be disassembled for rework, the force rod 133 is grasped to drive the locking cylinder 130 to rotate counterclockwise. When the locking cylinder 130 rotates counterclockwise, the main part 310 moves upward in the first installation groove 340 until it is completely disengaged. After the locking cylinder 130 is disengaged, the four locking members 114 lose their constraints and open to both sides. At this time, the locking members 114 rotate in all directions under the pull of the spring 116 at the rear end. When the block 115 is not in contact with the slot 121 on the fixing column 120, When engaged, the auxiliary component 320 can drive the installation column to disengage from the second installation groove 350 on the main component 310, and then complete the disassembly. During installation, when the auxiliary component 320 moves closer to the main component 310, the two fixing plates 210 at both ends of the auxiliary component 320 will fit with the main component 310, and any one of the first through holes 230 will be located on the corresponding second threaded hole 370, and then four bolts 220 are installed into the first through holes 230 and the second threaded holes 370 to further reinforce the auxiliary component 320 and the main component 310.

[0045] Two connecting holes 380 are provided on both sides of the main component 310, and a pressure sensor 250 is installed on the end of the inner wall of any of the second threaded holes 370 away from the auxiliary component 320, and a signal line 260 is installed on the opposite outer side of any of the pressure sensors 250, and a small buzzer 270 is installed on the end of any of the signal lines 260 away from the corresponding signal sensor, and any of the signal lines 260 and the small buzzer 270 are installed in the corresponding connecting hole 380; the output end of any of the pressure sensors 250 is connected to the input end of the external terminal.

[0046] During operation, when the main component 310 and the auxiliary component 320 are tightly connected, the four brackets 330 installed at the lower end of the auxiliary component 320 will apply pressure to the pressure sensor 250 at the bottom end of the mounting hole 360. When the auxiliary component 320 and the main component 310 become loose, the four brackets 330 installed at the bottom end of the auxiliary component 320 will lose the pressure on the pressure sensor 250. When the pressure sensor 250 loses pressure, the signal line 260 will control the small buzzer 270 to make a sound to warn the surrounding staff, and the pressure sensor 250 will send a new signal to the external terminal so that the external monitoring personnel can carry out maintenance in time.

[0047] The difference from the above scheme is that Figure 7 and Figure 8 As shown, a vertical groove 118 is provided on the first mounting block 110, a horizontal groove 1 is provided at the bottom of the vertical groove 118 and is arranged on the side away from the fixed column 120, and a rotating groove is provided at the top and is located on the side away from the fixed column 120, the bearing 111 is slidably installed in the vertical groove 118 and the horizontal groove 1, a side sliding groove 341 is provided on the inner wall of the first mounting groove 340, a horizontal groove 2 is provided at the bottom of the side sliding groove 341 and is arranged on the side away from the fixed column 120, and a rolling member 119 is provided on the side of the locking member 114 facing away from the fixed column 120, and the rolling member 119 is slidably fitted in the side sliding groove 341 and the horizontal groove 2;

[0048] The bottom of the locking member 114 is provided with an inner hook portion 1141 and a socket gap is reserved between the inner hook portion 1141 and the inner wall of the locking member 114;

[0049] The bottom of the fixing column 120 is provided with an inner countersunk hole 122 , and the side of the inner countersunk hole 122 is provided with an inner groove, and the inner groove is adapted to the inner hook 1141 .

[0050] During implementation, when the fixing column 120 moves downward, the inner hook 1141 enters into the inner countersunk hole 122, and when the end of the fixing column 120 fits against the part between the inner hook 1141 and the locking piece 114, the locking piece 114 will rotate, that is, the bearing 111 has a rotating groove entering into the vertical groove 118, the block 115 and the groove 121 are hooked and move together to the bottom of the first mounting groove 340, when the bearing 111 enters into the bottom of the vertical groove 118 and the rolling element 119 enters into the bottom of the side sliding groove 341, the spring 116 will pull the locking piece 114 outward, causing the rolling element 119 to enter into the horizontal groove two, and the bearing 111 enters into the horizontal groove one, and at the same time the inner hook 1141 and the inner groove are adapted to complete the connection. When removal is required, the locking cylinder 130 moves downward until it can no longer move downward, and the locking cylinder 130 rotates counterclockwise upward at the same speed as the speed at which the auxiliary component 320 disengages from the gradual 310. When the bearing 111 returns to the top of the vertical groove 118 and the rolling element 119 returns to the top of the side sliding groove 341, the spring 116 will turn the locking element 114 outward, the bearing 111 enters the rotating groove, and the block 115 and the groove 121 are separated.
