Description

Technical Field

[0001] The utility model relates to the technical field of tower crane safety facilities, and particularly relates to a tower crane anti-climbing device. Background Art

[0002] Tower cranes are mainly used for material transportation in construction. Standard sections are used to lift construction raw materials such as steel bars, concrete, and steel pipes, providing convenience for construction. A climbing ladder is arranged inside the tower crane along the height direction of the tower crane. Since tower crane construction involves the risk of working at heights, if non-operating personnel climb to the top of the tower or other high-rise buildings through the climbing ladder, there will be great potential safety hazards.

[0003] In the prior art, to prevent non-operating personnel from climbing the tower crane, an isolation enclosure is usually set around the tower crane at the bottom as an anti-climbing device. A conventional isolation enclosure is generally 1.8 m high and covers an area of 4 m × 4 m, and the surrounding area within a certain range of the tower crane is enclosed by the isolation enclosure. The isolation enclosure is generally assembled by combining square pipes and wire meshes or by combining square pipe grids, which requires on-site cutting and welding, is cumbersome to install, and cannot be reused. Moreover, the height and floor area of the isolation enclosure will affect the erection of formwork and subsequent wall construction during the construction stage. When erecting formwork, the formwork within the enclosed area of the isolation enclosure will be separated into independent parts by the isolation enclosure and cannot be connected to the surrounding formwork, resulting in poor integrity and stability of the formwork; or the isolation enclosure is removed, but without anti-climbing measures, the tower crane cannot prevent non-operating personnel from freely going up and down.

[0004] Therefore, the present application provides a tower crane anti-climbing device that is convenient to install, does not affect the erection of formwork, and can effectively prevent non-operating personnel from climbing the tower crane. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a tower crane anti-climbing device, aiming to improve the problems that the existing anti-climbing device affects construction and is inconvenient to install.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A rotating member hinged to the first baffle or the second baffle is arranged on one side of the door panel, and a locking member for locking or separating from the first baffle or the second baffle is arranged on the other side of the door panel; and

[0010] The peripheral baffle is arranged outside the tower crane standard section. There are four peripheral baffles. One peripheral baffle is spliced on one side of the inner protection plate, and a number of connecting pieces connected to the cross beam of the tower crane standard section are arranged at the splicing position of the peripheral baffle and the inner protection plate.

[0011] Preferably, first avoidance notches are arranged at the four vertex positions of the inner protection plate, and two second avoidance notches are symmetrically arranged on the same side of the peripheral baffle;

[0012] The first avoidance notch at the vertex of one inner protection plate and the two second avoidance notches on two adjacent peripheral baffles are combined to form a through opening for avoiding the column of the tower crane standard section.

[0013] Preferably, the rotating part is a hinge or a pin shaft.

[0014] Preferably, the connecting piece is a U-shaped bolt, and the U-shaped groove of the U-shaped bolt is connected to the cross beam of the tower crane standard section and locked to the peripheral baffle and / or the inner protection plate;

[0015] A pressing piece is arranged between the nut of the U-shaped bolt and the peripheral baffle and / or the inner protection plate.

[0016] Preferably, L-shaped splicing pieces are arranged on the splicing surfaces of the first baffle, the second baffle and the peripheral baffle, and locking bolts are arranged on the L-shaped splicing pieces.

[0017] Preferably, it further includes side baffles. There are four side baffles, and one side baffle is vertically arranged on the side of one peripheral baffle.

[0018] Preferably, the first baffle, the second baffle, the peripheral baffle, the side baffle and the door panel are steel mesh plates.

[0019] Preferably, an anti-rust layer is arranged on the first baffle, the second baffle, the peripheral baffle, the side baffle and the door panel.

[0042] Embodiment

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in

[0044] Among them, the inner protection plate 10 is formed by splicing a door plate 101, two first baffle plates 102 and two second baffle plates 103, and is horizontally arranged inside the tower crane standard section to prevent non-operating personnel from climbing to the top of the tower or other high-rise buildings through the climbing ladder. Specifically, the door plate 101 is of a rectangular structure, the first baffle plates 102 and the second baffle plates 103 are of triangular structures, and a rectangular notch is provided at the vertex position of the second baffle plate 103, and the rectangular notch is half the area of the door plate 101. When splicing the inner protection plate 10, the rectangular notch of the second baffle plate 103 cooperates with the two adjacent sides of the door plate 101, the two hypotenuses of the two adjacent first baffle plates 102 cooperate with each other, the two hypotenuses of the two adjacent second baffle plates 103 cooperate with each other, and the hypotenuse of the adjacent first baffle plate 102 cooperates with the hypotenuse of the second baffle plate 103. In this way, the two first baffle plates 102 and the two second baffle plates 103 are sequentially spliced around the door plate 101 to form a rectangular inner protection plate 10.

[0045] Moreover, a rotating member (not shown in the figure) hinged to the first baffle plate 102 or the second baffle plate 103 is provided on one side of the door plate 101, and a locking member (not shown in the figure) for locking or separating from the first baffle plate 102 or the second baffle plate 103 is provided on the other side of the door plate 101. That is, the door plate 101 can be rotated to open and close. When the door plate 101 is opened, operating personnel can pass through the door opening to achieve the purpose of climbing up and down; by locking the door plate 101 with the locking member, it can prevent non-operating personnel from climbing to the top of the tower or other high-rise buildings through the climbing ladder, and achieve a good safety protection effect. And because the position of the door plate 101 is in the middle, even if sundries accumulate on the surface of the tower crane anti-climbing device, the door plate 101 can still be opened.

[0046] To further improve the safety protection effect, the peripheral baffle plate 11 is horizontally arranged outside the tower crane standard section, and there are four peripheral baffle plates 11, and one peripheral baffle plate 11 is spliced on one side edge of the inner protection plate 10. By setting the peripheral baffle plate 11, the safety protection range of the tower crane anti-climbing device is expanded to the outside of the tower crane standard section, preventing non-operating personnel from climbing along the outside of the tower crane. At the same time, the peripheral baffle plate 11 can also be used to receive the falling sundries and reduce the occurrence of accidents.

[0047] In addition, a plurality of connecting members 12 connected to the cross beam of the tower crane standard section are provided at the splicing position of the peripheral baffle plate 11 and the inner protection plate 10. Specifically, when assembling the tower crane anti-climbing device, the inner protection plate 10 can be spliced first, and then the peripheral baffle plate 11 is pulled up by a cable and spliced with the inner protection plate 10. After splicing, the cross beam of the tower crane standard section and the splicing position of the peripheral baffle plate 11 and the inner protection plate 10 are connected through the connecting members 12, so as to install the tower crane anti-climbing device on the cross beam of the tower crane standard section, and to a certain extent strengthen the structural strength at the splicing position of the peripheral baffle plate 11 and the inner protection plate 10.

[0048] In this way, the tower crane anti-climbing device is installed on the cross beam of the tower crane standard section. The inner protection plate 10 is located inside the tower crane standard section, and the peripheral baffle 11 extends a certain distance towards the outside of the tower crane standard section. While ensuring the safety protection effect, it will not interfere with the formwork erection and can effectively avoid affecting the construction. Moreover, the tower crane anti-climbing device adopts a assembled structure, which is convenient for disassembly and assembly. After disassembly, it can also reduce the occupied space, facilitate transportation and storage, and can be reused. And because the tower crane anti-climbing device needs to be installed at a certain height position of the tower crane standard section, the assembled structure is more convenient for hoisting and installation than the integral structure, and has good practicability.

[0049] As Figure 1 , Figure 2 and Figure 3 shown, in this embodiment, first avoidance notches 131 are provided at the four top corner positions of the inner protection plate 10, and two second avoidance notches 132 are symmetrically provided on the same side edge of the peripheral baffle 11. Therefore, when the four peripheral baffles 11 are spliced around the four side edges of the inner protection plate 10, the first avoidance notch 131 at one top corner of the inner protection plate 10 and the two second avoidance notches 132 on two adjacent peripheral baffles 11 can be combined to form a through opening 13 for avoiding the column of the tower crane standard section. Thus, when the tower crane anti-climbing device is installed on the cross beam of the tower crane standard section, the column of the tower crane standard section can pass through the through opening 13 to avoid interference.

[0050] In this embodiment, the rotating member is a hinge or a pin shaft, and the door panel 101 can be hinged to the first baffle 102 or the second baffle 103 through a hinge or a pin shaft.

[0051] As Figure 5 shown, in this embodiment, the connecting member 12 is a U-shaped bolt. The U-shaped groove of the U-shaped bolt is connected to the cross beam of the tower crane standard section and locked to the peripheral baffle 11 and / or the inner protection plate 10. A pressing piece 121 is provided between the nut of the U-shaped bolt and the peripheral baffle 11 and / or the inner protection plate 10. In this way, the tower crane anti-climbing device is installed on the cross beam of the tower crane standard section through the pressing piece 121 and the U-shaped bolt. The two locking points of the U-shaped bolt and the locking points where the peripheral baffle 11 and the inner protection plate 10 are connected form a stable three-point connection structure to ensure the stability of the tower crane anti-climbing device.

[0052] As Figure 4 and Figure 5 shown, in this embodiment, L-shaped splicing members 15 are provided on the splicing surfaces of the first baffle 102, the second baffle 103 and the peripheral baffle 11, and locking bolts 151 are provided on the L-shaped splicing members 15.

[0053] Specifically, the adjacent first baffle 102 and / or second baffle 103, and the peripheral baffle 11 and the inner protection plate 10 are connected by an L-shaped splicing member 15. The vertical sides of two adjacent L-shaped splicing members 15 are aligned and fixedly connected by a locking bolt 151. Connecting with the locking bolt 151 is convenient for disassembly and assembly, and convenient for storage and transportation.

[0054] As Figure 6 and Figure 7 shown, in this embodiment, it further includes side baffle plates 14. There are four side baffle plates 14, and one side baffle plate 14 is vertically arranged on the side of one peripheral baffle 11.

[0055] Specifically, the inner protection plate 10 and the peripheral baffle 11 are horizontally arranged on the cross beam of the tower crane standard section, while the side baffle plate 14 is vertically arranged relative to the inner protection plate 10 and the peripheral baffle 11, and is bolted and fixedly connected to the side of the peripheral baffle 11. When assembling the tower crane anti-climbing device, the peripheral baffle 11 and the side baffle plate 14 can be assembled on the ground and then pulled up by a cable and connected to the inner protection plate 10. In this way, the connection structures between the first baffle 102, the second baffle 103, the peripheral baffle 11 and the side baffle plate 14 are all detachable, and the disassembly and assembly are convenient, which is convenient for storage and transportation.

[0056] Furthermore, the side baffle plate 14 is vertically arranged towards the top or bottom direction of the tower crane standard section, so as to increase the vertical protection and prevent non-operating personnel from climbing over the peripheral baffle 11 when climbing along the outside of the tower crane.

[0057] In this embodiment, the first baffle 102, the second baffle 103, the peripheral baffle 11, the side baffle plate 14 and the door plate 101 are steel mesh plates. Since the structure of the steel mesh plate is light, it is convenient for hoisting and installation, making the installation more convenient, and the integrity of the steel mesh plate is firm and it can be reused.

[0058] In this embodiment, an anti-rust layer (not shown in the figure) is provided on the first baffle 102, the second baffle 103, the peripheral baffle 11, the side baffle plate 14 and the door plate 101. Since the tower crane anti-climbing device is used outdoors, it is prone to rusting when exposed to sunlight and rain, which will affect the service life. Therefore, anti-rust paint is coated on the first baffle 102, the second baffle 103, the peripheral baffle 11, the side baffle plate 14 and the door plate 101 to form an anti-rust layer, so that the tower crane anti-climbing device has the property of anti-rust, thereby extending the service life and improving the reuse rate.

[0059] In this embodiment, a warning paint layer (not shown in the figure) is provided on the door panel 101. Specifically, applying colored paint on the surface of the door panel 101 to form the warning paint layer can not only enhance the aesthetics of the tower crane anti-climbing device, but also warn non-operating personnel against climbing the tower crane, and can also serve to indicate the position of the door panel 101 to the operating personnel, thereby reducing the troubles caused by non-operating personnel randomly climbing the tower crane and reducing potential safety hazards.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
