Description

Technical Field

[0001] The utility model belongs to the technical field of scaffold protection, and particularly relates to an anti-tipping device for a scaffold. Background Technique

[0002] A scaffold is a working platform erected to ensure the smooth progress of each construction process. It can be divided into an external scaffold and an internal scaffold according to the erected position; it can be divided into a wooden scaffold, a bamboo scaffold, and a steel pipe scaffold according to different materials; it can be divided into a vertical pole scaffold, a bridge scaffold, a portal scaffold, a suspended scaffold, a hanging scaffold, a cantilever scaffold, and a climbing scaffold according to the structural form.

[0003] During the use of the scaffold, in order to prevent the scaffold from tipping over, an anti-tipping device is usually set to support the scaffold. The existing anti-tipping device for a scaffold cannot adjust the deployment degree according to the height of the scaffold during use. When the scaffold is relatively high, if the deployment degree of the anti-tipping device is small, the stability of the scaffold during use will be reduced, thereby increasing the probability of the scaffold tipping over, which is not convenient for people to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-tipping device for a scaffold with a simple structure and reasonable design in order to solve the above problems.

[0008] As a further optimized scheme of the utility model, the locking component includes a screw rod, a nut used in cooperation with the screw rod, and a first fixing hole opened in the two fixing blocks and used in cooperation with the screw rod.

[0021] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following detailed implementation modes are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] As Figures 1 - 6As shown in the figure, an anti-tipping device for a scaffolding includes two fixing mechanisms 1. A first support member 2 is provided on one of the fixing mechanisms 1, and two second support members 3 are provided on the other fixing mechanism 1. The fixing mechanism 1 includes a mounting frame 11. Arc-shaped plates 12 are hinged at both ends of the mounting frame 11. Fixing blocks 13 are installed on one side of the two arc-shaped plates 12. First fixing holes 16 that cooperate with each other are formed inside the two fixing blocks 13. A screw rod 14 is commonly screwed inside the two first fixing holes 16, and a nut 15 for locking the two fixing blocks 13 is screwed on the outer part of the screw rod 14. During installation, the two arc-shaped plates 12 are sleeved outside the scaffolding. After the fixing mechanism is adjusted to a suitable position, the screw rod 14 is passed through the two first fixing holes 16 in sequence, and the screw rod 14 is tightened by the nut 15, so that the fixing mechanism is clamped on the scaffolding. The fixing mechanism can conveniently lock the first support member and the second support member on the scaffolding and is easy to disassemble. By loosening the fixing mechanism, the connection points of the first support member and the second support member with the scaffolding can be adjusted, with stronger adaptability. Among them, the first support member 2 includes a first support cylinder 21, a first support rod 22 that is slidably connected inside the first support cylinder 21 and one end of which extends outside the first support cylinder 21, and a plurality of first mounting holes 42 formed on the outer part of the first support rod 22. A first threaded hole 43 that cooperates with the plurality of first mounting holes 42 is formed on the first support cylinder 21. A first bolt 41 is commonly screwed inside the first threaded hole 43 and one of the first mounting holes 42. Among them, the second support member 3 includes a second support cylinder 31, a second support rod 33 that is slidably connected inside the second support cylinder 31 and one end of which extends outside the second support cylinder 31, a plurality of second mounting holes 34 formed on the outer part of the second support rod 33, and a second threaded hole 35 formed on the outer part of the second support cylinder 31 and that cooperates with the plurality of second mounting holes 34. A third bolt 32 is commonly screwed inside the second threaded hole 35 and one of the second mounting holes 43. A sleeve plate 52 is sleeved on the outer part of the first support rod 22. Second fixing holes 53 that cooperate with the plurality of first mounting holes 42 are formed on the outer part of the sleeve plate 52. A second bolt 51 is screwed inside the second fixing hole 53 and one of the first mounting holes 42. During the process of adjusting the deployment degree of the first support member, since the sleeve plate 52 is slidably connected to the outer part of the first support rod 22, it will not affect the deployment degree of the first support member, and one of the second support members can support the first support rod 22, thereby further improving the stability of the device during use. After the deployment degree of the first support member is adjusted, the sleeve plate 52 can be fixed on the outer part of the first support rod 22 by the second bolt 51. One end of the first support cylinder 21 is hinged inside one of the mounting frames 11. One end of each of the two second support rods 33 is hinged inside the other mounting frame 11. One end of one of the second support cylinders 31 is hinged to the outer part of the first support cylinder 21.One end of another second support cylinder 31 is hinged to the outside of the sleeve plate 52. One ends of the first support rod 22 and the second support rod 33 located inside the first support cylinder 21 and the second support cylinder 31 are both in a T-shaped structure to prevent the first support rod 22 and the second support rod 33 from sliding out of the inside of the first support cylinder 21 and the second support cylinder 31 during the sliding process.

[0023] It should be noted that for this anti-tipping device for a scaffolding, when in use, the two fixing mechanisms are respectively installed on the scaffolding, and the two fixing mechanisms are in the same horizontal plane in the vertical direction. At the same time, during the installation process, the distance between the two fixing mechanisms can be adjusted according to the height of the scaffolding. During the process of adjusting the distance between the two fixing mechanisms, the first support rod 22 will slide inside the first support cylinder 21. When it is necessary to adjust the deployment degree of the first support member 2, it can be rotated around the hinge point between the first support rod 22 and one of the mounting brackets 11. At this time, the second support rod 33 will slide inside the second support cylinder 31. After the distance between the two fixing mechanisms and the deployment degree of the first support member are adjusted, the first support rod 22 can be fixed to the first support cylinder 21 through the first bolt 41, and the second support rod 33 can be fixed to the second support cylinder 31 through the third bolt 32. Since a triangular area is formed between the two second support members and the first support member, when the first support member is impacted, the device is made more stable.

[0024] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
