A clamping plate 10 is provided inside the left unit prefabricated module 7. A right unit prefabricated module 9 is fixedly connected to the right end face of each clamping plate 10. Fixed cylinders 11 are fixedly connected inside both the left unit prefabricated module 7 and the right unit prefabricated module 9. The fixed cylinders 11 can ensure the stable penetration of the connecting rod 13 and have a guiding effect.

[0030] Limit pins 8 distributed front and back are fixedly connected to the lower end face of the left unit prefabricated module 7. The left unit prefabricated module 7 located below is engaged with the base 6 through the limit pins 8. Limit pins 8 distributed front and back are fixedly connected to the lower end face of the right unit prefabricated module 9. The right unit prefabricated module 9 located below is engaged with the base 6 through the limit pins 8. The left unit prefabricated modules 7 and the right unit prefabricated modules 9 are engaged with each other through the limit pins 8; the setting of the limit pins 8 can make the prefabricated modules fit tightly and are not prone to loosening.

[0031] The inside of the left unit prefabricated module 7 is hollow. Grooves are formed inside the clamping plate 10, and the clamping plate 10 is fixedly connected to the left unit prefabricated module 7 through a connecting shaft. This setting can enable the prefabricated modules to be assembled with each other, which can greatly shorten the construction period.

[0032] Vertical limit grooves are formed on both the left and right sides of the upper end face of the base 6, and the limit grooves are vertically aligned with the fixed cylinders 11. The depth of the limit grooves is 0.8 times the height of the base 6; this setting can enable the connecting rod 13 to pass through the prefabricated module and penetrate into the inside of the base 6, and then be limited and fixed through the limit shaft 12.

[0033] Limit shafts 12 distributed front and back are screwed to both the left and right sides of the base 6. The number of limit shafts 12 is four. The area of the lower end face of the base 6 is 1.5 times the area of the upper end faces of the left unit prefabricated module 7 and the right unit prefabricated module 9. The base 6 is provided with a large area to ensure its stability. The prefabricated modules can be conveniently assembled, saving construction time. At the same time, the prefabricated modules can be disassembled and recycled to avoid waste of resources.

[0034] The connecting component includes a base plate 4 and a connecting rod 13. A limit frame 14 is fixedly connected to the upper end surface of the base plate 4. Connecting screws 15 are provided inside the limit frame 14. The limit frame 14 is fixedly connected to the base plate 4 through the connecting screws 15. A sliding plate 16 is slidably connected inside the limit frame 14. Connecting pins 17 arranged in a matrix are provided on the upper end surfaces of the sliding plates 16. Threaded holes 18 are provided at the positions of the limit frame 14 on both sides of the connecting screws 15. The connecting pins 17 pass through the sliding plates 16 and are screwed to the limit frame 14 through the threaded holes 18. The upper end surfaces of the sliding plates 16 are fixedly connected to the fixing seat 2 through fixing screws 3. By adjusting the sliding plates 16 at different positions, various types of lifting equipment can be installed, expanding the scope of use.

[0035] The limit frame 14 is arranged in an X shape and is embedded inside the base plate 4. The upper end surface of the limit frame 14 is flush with the upper end surface of the base plate 4. This setting ensures that the upper end surface of the base plate 4 is flat and guarantees its normal use.

[0036] The lower end surface of the base plate 4 is fixedly connected with connecting rods 13 arranged in a matrix. A connecting groove arranged horizontally is provided below the connecting rods 13. By inserting a limit shaft 12 into the connecting groove inside the connecting rod 13, the connecting rod 13 can be fixed at this time, and the fixing function can be realized.

[0037] The usage method includes the following steps:

[0038] Step 1: Dig a foundation trench at a specified place. By installing the ground pile components one by one into the foundation trench, its large-area base 6 can enhance the stability of the foundation.

[0039] Step 2: Insert the connecting component into the ground pile component. At this time, the stability of the connecting component can be strengthened. Then, fix the fixing screw 3 and the tower frame 1 through the fixing seat 2. At this time, the tower frame can complete the installation work.

[0040] Step 3: When different equipment needs to be replaced, the fixing seat 2 can be rotated at this time, and then the internal components of the connecting component can be moved. At this time, the installation position can be adjusted. At this time, connection work can be carried out for different lifting equipment, expanding the scope of use.

[0041] During use, dig a foundation pit at the specified location, then place it therein through the bottom plate 6, and then install the left unit prefabricated module 7 and the right unit prefabricated module 9 through the limit pin 8. The left unit prefabricated module 7 and the right unit prefabricated module 9 are installed in cooperation with the clamping plate 10 and the connecting shaft. When the left unit prefabricated module 7 and the right unit prefabricated module 9 are installed, at this time, install the base plate 4 on the upper end surfaces of the left unit prefabricated module 7 and the right unit prefabricated module 9 at the uppermost part. The connecting rod 13 below the base plate 4 is inserted into the fixed cylinder 11 inside the left unit prefabricated module 7 and the right unit prefabricated module 9, and then extends into the floor 6. By rotating the limit shaft 12, the limit shaft 12 can be inserted into the connecting groove inside the connecting rod 13 to achieve the purpose of fixedly connecting the connecting rod 13 and the base plate 4. The limit frame 14 above the base plate 4 is fixed by the connecting screw 15. At this time, the sliding plate 16 is fixed by the connecting pin 17, and then the tower crane frame 1 and the fixed seat 2 are fixed on the sliding plate 16 through the fixing screw 3. This setting has a short construction period, low labor intensity, saves costs, avoids resource waste, and has good use value.
