[0025] like Figure 1 and Figure 2As shown, a tower crane foundation protection device of this embodiment is used to protect the tower crane foundation, including a protection member 1 and a positioning rod 2. The protection member 1 is placed in an enclosure around the tower crane foundation to protect the tower crane foundation. The protection member 1 includes a protection fence 11 and a protection door 12. The protection fence 11 includes a plurality of horizontal rods 111, a plurality of vertical rods 112 arranged along the length direction of the horizontal rods 111, a vertical connector 113 for vertical connection and a corner connector 114 for corner connection. Two adjacent horizontal rods 111 are connected into an L-shaped structure through the corner connector 114, so that the four horizontal rods 111 are connected through the corner connector 114 to form an enclosure structure connected end to end. The vertical connector 113 is sleeved on the horizontal rod 111 so that the vertical rod 112 is fixedly installed on the horizontal rod 111 through the vertical connector 113. Optionally, a protective net is also installed on the protective fence 11, and the protective net is movably connected to the horizontal rod 111 and / or the vertical rod 112 to prevent outsiders from climbing into the protective fence 11; optionally, the protective net is a galvanized steel wire mesh. A door opening is reserved on one side of the protective fence 11 for installing a protective door 12, and the protective door 12 includes a door body 121 and a connecting rod 122 for fixed connection with the protective fence 11. The door body 121 is arranged in the door opening between the two vertical rods 112, and the connecting rod 122 is fixed to both sides of the door body 121 and arranged horizontally toward the direction of the vertical rod 112. The vertical rods 112 on both sides of the door body 121 are sleeved with vertical connecting pieces along the axial direction, so that the connecting rod 122 is fixedly connected to the vertical rod 112 through the vertical connecting piece 113, thereby fixing the door body 121. Preferably, the protective door 12 is arranged at the middle position of one side of the protective fence 11. The positioning rod 2 is arranged at the four corners inside the protective member 1. The side of the positioning rod 2 is movably matched with the protective fence 11, and the bottom is fixedly connected to the ground at the tower crane foundation, so as to position the protective member 1 around the tower crane foundation and provide auxiliary support for the protective member 1 to prevent the protective member 1 from tilting, so that the protective member 1 can be firmly enclosed around the tower crane foundation to protect the tower crane foundation. By arranging the positioning rod 2 at the four corners inside the protective member 1 and fixing its bottom to the ground at the tower crane foundation, the protective member 1 can be firmly positioned, the protective member 1 can be prevented from tilting, and the safety of the device for protecting the tower crane foundation can be improved.

Then, the vertical rods 112 are inserted into the vertical connectors 113 from top to bottom in sequence so that they are connected to the horizontal rod 111 through the vertical connectors 113. At this point, the assembly of one side of the protective fence 11 is completed. Repeat this step to complete the assembly of the three sides of the protective fence 11. After the three sides of the protective fence 11 are assembled, the horizontal rods 111 of the two adjacent sides are connected by the corner connectors 114 to connect the three sides into an integral part, and then the integral part is placed on the ground at the tower crane foundation so that it surrounds the tower crane foundation on three sides; then the protective door 12 is installed on the protective fence 11 to assemble the protective part 1 as a whole. Specifically, the vertical connectors 113 are sleeved on the connecting rods 122 on both sides of the door body 121, and then the vertical rods 112 are inserted into the vertical connectors 113, so that the connecting rods 122 and the vertical rods 112 are fixedly connected through the vertical connectors 113, so that The protective door 12 is positioned on the vertical rod 112 through the connecting rod 122, and then the two sides of the protective fence 11 on both sides of the protective door 12 are assembled.

Specifically, a plurality of vertical connecting members 113 are sleeved on the horizontal rods 111 on both sides of the protective door 12, and then the vertical rods 112 are sequentially inserted into the vertical connecting members 113 from top to bottom, so that the protective fence 11 on the side of the protective door 12 is completed. The protective element 1 is assembled on the surface, and this step is repeated to complete the assembly of the two surfaces of the protective fence 11 on both sides of the protective door 12, and then one end of the horizontal rod 111 on this surface is inserted into the vertical connector 113 on the vertical rod 112 on both sides of the protective door 12, so as to connect and fix the protective door 12 with the protective fence 11 on both sides to form the fourth surface of the protective element 1, and the horizontal rod 111 on the fourth surface of the completed protective element 1 is connected to the three surfaces of the completed protective fence 11 through the corner connector 114 to form an enclosure structure, thereby completing the assembly of the protective element 1, and the completed protective element 1 forms a four-sided enclosure structure for the tower crane foundation. Finally, the positioning rod 2 is placed at the four corners inside the protective element 1, and the bottom of the positioning rod 2 is fixedly connected to the ground at the tower crane foundation, so that the positioning rod 2 can position and assist in supporting the protective element 1, thereby achieving effective protection of the tower crane foundation.
