Description

Technical Field

[0001] The utility model relates to the technical field of monitoring camera installation, in particular to a video monitoring installation ladder used for outdoor complex terrain. Background Art

[0002] When our company installs and maintains many surveillance cameras within the jurisdiction, we need to use ladders. The existing outdoor surveillance maintenance ladders are mainly straight ladders and deformable ladders. The disadvantage is that it is difficult to ensure sufficient safety and stability when facing complex and changeable outdoor terrain. On uneven ground, it is impossible to ensure that the skeletons of the two ladders and the ground support are stressed, resulting in an unstable center of gravity when people step on the ladder, which is easy to shake or even slide or fall sideways. The pedals and monitoring columns at the top of the ladder are also single stress points, and the center of gravity of the climber will also swing left and right due to the instability of the ground support point, which will bring greater safety risks to construction and maintenance personnel.

The holding rod device 20 is installed at the upper end of the ladder body 10, and the upper end of the ladder body 10 is limited by the holding rod device 20. The telescopic rod 30 is installed at the lower end of the ladder body, and the telescopic rod 30 enables the two frames 11 of the ladder body 10 to be supported by the ground when the ladder is on an uneven ground.

[0034] In this embodiment, see Figure 2 , mounting holes 12 are respectively provided on the skeletons 11 on both sides of the ladder body 10, and damping sleeves 13 are installed in the mounting holes 12. Two connecting rods 21 pass through the damping sleeves 13 on both sides respectively, and a fastener 22 is installed at one end of the connecting rod 21 extending from the damping sleeve 13, which can prevent the holding rod device 20 from rotating arbitrarily when the ladder is erected. Specifically, the damping sleeve 13 is made of rubber, and the damping sleeve 13 is interference-fitted with the mounting hole 12, and there is damping between the damping sleeve 13 and the connecting rod 21. The fastener 22 can be a latch or a nut. In this embodiment, the fastener 22 preferably adopts a nut, which can not only fix the damping sleeve 13 and the connecting rod 21, but also adjust the damping size between the damping sleeve 13 and the connecting rod 21 by twisting the nut. When tightening the nut, the nut squeezes the damping sleeve 13, and the damping sleeve 13 deforms and squeezes the connecting rod 21, thereby increasing the damping between the damping sleeve 13 and the connecting rod 21.

[0035] See also Figure 3 , 4 A friction pad 24 is installed in the arc plate 23 to increase the friction between the arc plate 23 and the monitoring column 40 and prevent the arc plate 23 from damaging the paint on the surface of the monitoring column 40. In this embodiment, the friction pad 24 is a rubber skin adapted to the arc plate 23. The friction pad 24 can be bonded in the arc plate 23.

[0039] In addition to the above structure, the holding device can also be tied with ropes.

[0040] In one solution, the telescopic rod 30 is screwed to the lower end of the frame 11, which is not shown in the figure.

[0041] In another embodiment, see Figure 2 The telescopic rod 30 is provided with a plurality of limiting holes 33 in the axial direction, and the lower end of the frame 11 is provided with a through hole. The telescopic rod 30 is slidably inserted into the frame 11, and the latch 32 is inserted into the through hole and the limiting hole 33, so as to limit the telescopic rod 30 and the frame 11. By inserting the latch 32 into different limiting holes 33 on the telescopic rod 30, the extension length of the telescopic rod 30 can be adjusted. If one side cannot support the ground during adjustment, it can be adjusted by padding with a wooden board.

[0042] Furthermore, an anti-skid pad 31 is installed at the lower end of the telescopic rod 30 to increase the friction between the telescopic rod 30 and the ground. In this embodiment, the anti-skid pad 31 is a bushing structure with a circular arc at the lower part, and the anti-skid pad 31 is sleeved on the lower end of the telescopic rod 30. In this embodiment, the anti-skid pad 31 is made of rubber.
