[0002] Traditional construction method: standard erection form, see Figure 1 ; GB / T19155-2017 "Suspended Platforms for Working at Height" 6.5.5.3 stipulates that when the outstretched distance of the counterweight suspension bracket is the largest and the hoisting mechanism is under the condition of the ultimate working load, the stabilizing moment shall be greater than or equal to 3 times the overturning moment (that is, in the normal working state, the ratio of the anti-overturning moment to the overturning moment of the suspended mechanism of the suspended platform ≥ 3).

[0003] Standard suspended platform: specifically refers to the ratio of the anti-overturning moment to the overturning moment of the suspended mechanism of the suspended platform ≥ 3, specifically refers to the front beam of the suspended platform being perpendicular to the parapet wall of the roof. Generally, the front beam of the suspended platform is perpendicular to the parapet wall of the roof, but in the actual working situation on site, there are often situations where the front beam of the suspended platform has a small angle with the parapet wall of the roof or the front beam is directly placed on the top of the parapet wall of the roof.

[0004] The traditional suspended platform device has the situation that the front beam of the suspended platform has a small angle with the parapet wall of the roof, and the front beam is directly placed on the top of the parapet wall of the roof, which does not conform to the anti-overturning calculation working condition of the standard suspended platform, is easy to slip and overturn, and then causes safety accidents, which is not conducive to the safe production operation of the suspended platform, and a special construction plan needs to be re-prepared.

[0027] The following will further describe the present utility model in detail Figures 1 - 3 with reference to the appended drawings.

[0028] Embodiment 1, as Figures 1 - 3As shown, in this embodiment, in order to solve the existing problems, the utility model discloses an anti-overturning member for a suspended platform for working at height, which includes a base 1 and a hoist 2 connected to the top thereof. A fixed support 3 is connected to the top of the base 1. The fixed support 3 is in an L shape. A sliding groove 4 is provided at the bottom of the fixed support 3. A locking screw rod 5 is slidably connected to the inner wall of the sliding groove 4. The locking screw rod 5 is threadedly connected to the base 1. A lifting screw rod 8 is threadedly connected to the top of the fixed support 3. The bottom of the lifting screw rod 8 is rotatably connected to a pressing member 7. A lifting groove 6 is provided on the inner side wall of the fixed support 3. The side surface of the inner wall of the lifting groove 6 is slidably connected to the pressing member 7.

[0029] A sliding support 9 is slidably connected to the side surface of the fixed support 3. The shape of the sliding support 9 is the same as that of the fixed support 3. The sliding support 9 is provided with a locking screw rod 5. The connection manner between the sliding support 9 and the locking screw rod 5 is the same as the connection manner between the fixed support 3 and the locking screw rod 5.

[0030] A lifting groove 6 is provided on the inner side wall of the sliding support 9. A telescopic pressing member 10 is slidably connected to the lifting groove 6. An opening is provided on one side of the pressing member 7 facing the telescopic pressing member 10. The telescopic pressing member 10 is slidably connected to the pressing member 7.

[0031] A telescopic screw rod 11 is threadedly connected to the outer side surface of the sliding support 9. The telescopic screw rod 11 is rotatably connected to one end of the fixed support 3 away from the locking screw rod 5.

[0032] A buffer pad is provided at the bottom of the pressing member 7. A sliding protrusion is provided on the side surface of the pressing member 7. The sliding protrusion is slidably connected to the inner wall of the lifting groove 6.

[0033] The specific working principle is that the installation and connection stability of the hoist 2 can be effectively improved through this device. Compared with the traditional device, the anti-tipping performance of the bottom of the hoist 2 can be effectively improved by this device.

[0034] When using this device, the fixed support 3 and the sliding support 9 are fixed on the base 1 through the locking screw rod 5. The structure of the sliding groove 4 can facilitate the device to align with the reserved hole positions on the base 1, reducing the use difficulty of the device. By rotating the telescopic screw rod 11, the sliding between the sliding support 9 and the fixed support 3 can be controlled, so that the side surfaces of the fixed support 3 and the sliding support 9 are in contact with the side surface of the base of the hoist 2. At the same time, when the device is actually used, the structure of the telescopic screw rod 11 can prevent the fixed support 3 and the sliding support 9 from accidentally sliding.

[0035] After the fixing brackets 3 and sliding brackets 9 of the present device are fixed, at this time, by rotating the lifting threaded rod 8, the pressing member 7 can be controlled to lift and slide, so that the pressing member 7 can contact and squeeze the top of the base of the hoist 2 downward, thereby effectively improving the limiting stability of the present device and reducing the risk of the hoist 2 tilting.
