[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pre-assembled structure for bolting a lifting tower panel, comprising: a tower body, a support ring being welded on the top wall of the tower body;

[0007] A mounting structure is installed on the inner side of the tower body, and the mounting structure includes a fixing block, which is fixedly welded to the bottom surface of the support ring, a mounting groove is provided on the top surface of the fixing block, a protrusion is integrally formed on the bottom surface of the mounting groove, a nut is placed on the inner side of the mounting groove, a platform panel body is placed on the top surface of the support ring, a bolt body is provided on the inner side of the top surface of the platform panel body, a plug block is placed on the upper side of the bolt body, a column is inserted into the top surface of the fixing block, a spring is fixedly connected to the bottom end of the column, and a slot is provided on the bottom surface of the platform panel body.

[0008] Preferably, the inner wall of the mounting groove fits with the outer wall of the nut.

[0009] Preferably, the bolt body passes through the platform panel body and the support ring, and the bolt body cooperates with the nut.

[0010] Preferably, the top surface of the plug is flush with the top surface of the platform panel body.

[0011] Preferably, the plug passes through the support ring, and the upper end is inserted into the slot.

[0012] Preferably, one end of the spring is fixedly connected to the bottom surface of the fixing block.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can pre-fix the nut on the bottom surface of the support ring through the fixing block, and the platform panel body can be fixed on the support ring from the upper side by the bolt body, which is easy to operate, and the insertion column matching slot is provided to guide and limit the position of the platform panel body on the top surface of the support ring, making the installation of the platform panel body more convenient and labor-saving.

[0014] The utility model is provided with an installation structure, and the nut is inserted into the installation groove. The protrusion cooperates with the installation groove, and the nut can be fixed so that the nut will not rotate and will not fall. The platform panel body is hoisted to the upper side of the support ring, and then the platform panel body is slowly lowered so that the bottom surface of the platform panel body contacts the top of the plug column that penetrates the top surface of the support ring. The platform panel body can press the plug column downward, so that the plug column descends inside the support ring and the fixing block, and stretches the spring to adjust the angle of the platform panel body, so that the platform panel body rotates on the upper side of the support ring to adjust the position of the slot. When the slot is aligned with the plug column up and down, the plug column rises under the action of the spring and is inserted into the inner side of the slot, so that the angle and position of the platform panel body on the top surface of the support ring can be fixed, and the bolt body and the nut are aligned up and down. At this time, only the bolt body needs to be rotated to screw the bolt body into the inner side of the nut to realize the fixed connection between the platform panel body and the support ring. Finally, the plug block is plugged into the top surface of the bolt body to continue to protect the bolt body, thereby improving the installation efficiency of the platform panel body and saving safety and effort.

[0022] The tower body 1 and the platform panel body 25 used in the present application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A pre-assembled structure for bolting a lifting tower panel, comprising: a tower body 1, a support ring 11 being welded on the top wall of the tower body 1;

[0024] A mounting structure 2 is installed on the inner side of the tower body 1, and the mounting structure 2 includes a fixing block 21, which is fixedly welded to the bottom surface of the support ring 11, and a mounting groove 22 is provided on the top surface of the fixing block 21, and a protrusion 23 is integrally formed on the bottom surface of the mounting groove 22, and a nut 24 is placed on the inner side of the mounting groove 22, and a platform panel body 25 is placed on the top surface of the support ring 11, and a bolt body 26 is provided on the inner side of the top surface of the platform panel body 25, and a plug block 27 is placed on the upper side of the bolt body 26, and a column 28 is inserted into the top surface of the fixing block 21, and a spring 29 is fixedly connected to the bottom end of the column 28, and a slot 210 is provided on the bottom surface of the platform panel body 25.

[0025] Furthermore, the inner wall of the mounting groove 22 fits with the outer wall of the nut 24 .

[0026] Furthermore, the bolt body 26 penetrates the platform panel body 25 and the support ring 11 , and the bolt body 26 and the nut 24 cooperate with each other.

[0027] Furthermore, the top surface of the plug 27 is flush with the top surface of the platform panel body 25 .

[0028] Furthermore, the plug post 28 passes through the support ring 11 , and the upper end is inserted into the slot 210 .

[0029] Furthermore, one end of the spring 29 is fixedly connected to the bottom surface of the fixing block 21.

[0030] Working principle: Before installation, insert the nut 24 into the installation groove 22, and the protrusion 23 cooperates with the installation groove 22 to fix the nut 24 so that the nut 24 will not rotate or fall off. Lift the platform panel body 25 to the upper side of the support ring 11, and then slowly lower the platform panel body 25 so that the bottom surface of the platform panel body 25 contacts the top of the plug post 28 that passes through the top surface of the support ring 11. The platform panel body 25 can press down the plug post 28, so that the plug post 28 drops inside the support ring 11 and the fixing block 21, and stretches the spring 29.

[0031] Then adjust the angle of the platform panel body 25 so that the platform panel body 25 rotates on the upper side of the support ring 11 to adjust the position of the slot 210. When the slot 210 is aligned with the plug 28, the plug 28 rises under the action of the spring 29 and is inserted into the inner side of the slot 210. The angle and position of the platform panel body 25 on the top surface of the support ring 11 can be fixed, and the bolt body 26 is aligned with the nut 24 up and down.
