[0038] Please refer to the attached document. Figure 1 - Figure 5 This application illustrates a tower crane bottom protective fence structure provided in an embodiment of the present application. It is used to install at the bottom of the tower crane support (generally, the tower crane support is a directional structure) to effectively protect the bottom of the tower crane, reduce safety risks, and ensure safe operation of the tower crane. Specifically, it includes: an overhead support frame, four sets of fence components, and four sets of folding guardrails 6.

[0039] The overhead support frame is fixed to the ground, typically using anchor bolts, expansion bolts, or ground anchors. At the top of the overhead support frame is a square frame 3, which provides space for installing four sets of fencing components. This square frame 3 is suspended in the air to prevent uneven ground or water accumulation from affecting the installation of the four sets of fencing components. The bottoms of the four sets of fencing components connect to the square frame 3 for easy installation. The four sets of fencing components interlock to form a square structure, ensuring stability after installation. It is relatively stable. One of the fence components has a door 5b on its side, which allows workers to enter (tower crane workers climb the tower crane via a ladder on the tower crane support). To further prevent debris from falling inside the four fence components, folding guardrails 6 are rotatably installed on the top of each of the four fence components. The shape of the folding guardrails 6 is an isosceles trapezoid. The four sets of folding guardrails 6 are in the shape of a quadrangular truncated pyramid, and adjacent folding guardrails 6 are fixed together by connectors 7. The four sets of folding guardrails 6 are square at the top and fit snugly against the tower crane support.

[0040] This application, through the design of an overhead support frame, can adapt to the installation needs of various uneven ground, and provides a square frame 3 for the installation of four sets of fence components, making the installation more convenient; and designs four sets of folding guardrails 6, which are rotatably installed on the top of the four sets of fence components. In specific installation, they are rotated upwards and combined to form a truncated quadrangular shape. Connectors 7 are used to fix them together to form a protective surface facing obliquely upwards, so as to improve the protective effect.

[0041] In one embodiment, such as Figure 1 As shown, the overhead support frame includes: a square frame 3, four angle steel support members 1 distributed at the four top corners of the square frame 3 and fixedly connected to the bottom surface of the square frame 3 at their top, and mounting plates 2 fixedly connected to the bottom ends of the four angle steel support members 1. The installation of the overhead support frame is carried out simultaneously with the construction of the tower crane support foundation. The square frame 3 is fitted on the outside of the tower crane support. After the tower crane is assembled to a certain height, four sets of fence components and four sets of folding guardrails 6 are installed.

[0042] When installing the protective fence structure at the bottom of the tower crane, first prepare the ground structure. The installation position can be prepared in advance by pouring concrete or burying foundation piles. Then, fix the mounting plate 2 to the ground with anchor bolts.

[0043] In one embodiment, such as Figure 5 As shown, the front of the square frame 3 is a hollow frame 3a, the left and right sides are horizontal U-shaped side frames 3b facing outwards, and the rear side is a platform 3d. The four sets of fence components are: two sets of side fences 4, front fence 5, and rear fence 8.

[0044] The bottom of the side fence 4 is provided with a first bottom support 4b corresponding to the horizontal U-shaped side frame 3b. The first bottom support 4b is locked in the horizontal U-shaped side frame 3b to realize the quick installation of the side fence 4. Both sides of the side fence 4 are fixedly connected with lock holes 4a. The bottom of the rear fence 8 is fixedly connected with a second bottom support 8b corresponding to the platform 3d. The second bottom support 8b is locked in the platform 3d to provide stable support for the rear fence 8. Both sides of the rear fence 8 are fixedly connected with second locking pins 8a corresponding to the lock holes 4a of the two horizontal U-shaped side frames 3b. In this way, the locking pins of the rear fence 8 and the two sets of side fences 4 are locked and connected. This connection method is simple and efficient. Both sides of the front fence 5 are fixedly connected with first locking pins 5a corresponding to the lock holes 4a of the two horizontal U-shaped side frames 3b. The front fence 5 is provided with a door 5b.

[0045] During the installation process, the user first installs the two sets of side railings 4. Specifically, the first base support 4b is secured to the horizontal U-shaped side frame 3b. At this point, the two sets of side railings 4 are not stable and require assistance from personnel. Then, the rear railing 8 is installed, with the second locking pins 8a on both sides of the rear railing 8 positioned in the locking holes 4a of the two sets of side railings 4. Since the two sets of side railings 4 are still unstable, they can be tilted to allow the second base support 8b to be secured in the platform 3d. The overall weight of the rear railing 8 is supported by the platform 3d. At this point, the structure consisting of the two sets of side railings 4 and the rear railing 8 is basically stable. Finally, the front railing 5 is installed, with the first locking pins 5a on both sides of the front railing 5 positioned in the locking holes 4a. The bottom of the front railing 5 is pressed against the top of the hollow frame 3a.

[0046] In one embodiment, in order to further increase the stability of the installation of the side fence 4 and the horizontal U-shaped side frame 3b, a first mounting hole 3c is provided on the horizontal U-shaped side frame 3b, and a second mounting hole 4d is provided on the first bottom support 4b. The first mounting hole 3c and the second mounting hole 4d are fixedly installed by bolts, and the bolt fixing structure is more reliable.

[0047] In one embodiment, in order to further increase the stability of the installation of the side fence 4 and the horizontal U-shaped side frame 3b, and to increase the resistance of the side fence 4 to lateral forces, a corner bracket 4c is fixedly connected to one end of the first bottom support 4b and the inner side of the hollow frame 3a, so as to prevent the side fence 4 from shaking.

[0048] In one embodiment, a pad 9 is provided at the bottom of the mounting plate 2. The pad 9 is a corrosion-resistant rubber plate to prevent the mounting plate 2 from directly contacting the ground and causing corrosion, and to provide tension for the bolt installation structure to prevent the bolts from loosening.

[0049] In one embodiment, a flexible or foldable baffle (not shown in the figure) is fixedly installed on the folding guardrail 6. The folding guardrail 6 is a skeleton structure that can block larger objects, while smaller objects are blocked by the baffle. When in use, the folding guardrail 6 is inclined and is generally used to guide falling objects to the outside of the protective fence structure at the bottom of the tower crane.
