Embodiment 1

[0046] Example 1: A reusable anti-climbing device for the bottom layer of a tower crane on a building construction site, including an eaves side frame and a central protective frame 3 .

[0047] The top-view angle of the eave side frame is a back-shaped structure. The eave side frame is used for horizontal installation on the outside of the standard section of the tower crane. The length of the eave side frame is adjustable in the front and rear and left and right directions.

[0048] Specifically, as figure 1 , figure 2 , image 3 and Figure 4 As shown, the eaves side frame includes a detachable first protective frame 1 and a second protective frame 2, the first protective frame 1 and the second protective frame 2 are both L-shaped frame structures, and the first protective frame 1 and the second protective frame The structure of the frame 2 is the same, and the first protective frame 1 and the second protective frame 2 are both length-adjustable structures in the front-...

Abstract

The invention provides the reusable tower crane bottom layer anti-climbing device on the building construction site, and the problem that the size of an existing tower crane bottom layer anti-climbing device cannot be adjusted, so that the existing tower crane bottom layer anti-climbing device cannot be suitable for tower crane standard knots of different specifications is solved. The device comprises an eave side frame and a central protection frame, the overlook angle of the eave side frame is of a concentric-square-shaped structure, the eave side frame is used for being horizontally installed outside a tower crane standard knot, and the eave side frame is of a length-adjustable structure in the front-back direction and the left-right direction. The center protection frame is used for being horizontally installed in a tower crane standard knot so as to seal an upper channel and a lower channel in the tower crane standard knot, the center protection frame is of a length-adjustable structure in the front-back direction and the left-right direction, a vertically-through door frame is fixedly arranged in the center protection frame, and a door plate capable of rotating up and down is hinged to the interior of the door frame. The free end of the door plate is detachably connected with the door frame through a lock catch.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to an anti-climbing device for the bottom layer of a tower crane that can be reused on a building construction site. Background technique [0002] Tower crane is a kind of equipment used for lifting on construction sites. It is usually also a tower crane. It is mainly used to lift construction materials such as steel bars, cement, and steel pipes on construction sites. , There is a phenomenon of people climbing in the standard section. In order to avoid people climbing, it is usually necessary to set an anti-climbing device on the bottom layer of the tower crane. [0003] However, the existing anti-climbing devices on the bottom of tower cranes have certain deficiencies that need to be improved: the existing anti-climbing devices are usually composed of three parts: a fixed bottom fence, a side fence and a central fence. The size of the part is usually fixed...
