[0032] like Figure 1-11 As shown, a climbing safety detection device includes a ladder 1 with a guardrail. Lifting rails 2 are provided on the two inner walls of the guardrail. The top of one lifting rail 2 is located at the top of the ladder 1, and a liftable upper detection mechanism 3 is provided on it. The bottom of the other lifting rail 2 is located at the bottom of the ladder 1, and a liftable lower detection mechanism 4 is provided on it. The length of the lifting rail 2 can be set according to the sliding distance required by the upper detection mechanism 3 and the lower detection mechanism 4.

[0033] The upper detection mechanism 3 includes a first lifting mechanism 30 and an upper detection camera 31 located at the bottom of the first lifting mechanism 30.

[0034] The lower detection mechanism 4 includes a second lifting mechanism 40 and a lower detection camera 41 disposed on the top of the second lifting mechanism 40.

[0035] Both the upper detection camera 31 and the lower detection camera 41 are high-definition cameras, with their viewing angles pointing downwards and upwards, respectively.

[0036] This design allows for comprehensive video monitoring of climbers using the upper detection camera 31 of the upper detection mechanism 3 and the lower detection camera 41 of the lower detection mechanism 4. This enables the determination of whether climbers are correctly wearing a series of personal protective equipment. In addition, by sliding the first lifting mechanism 30 and the second lifting mechanism 40 on the lifting track 2, the detection distance can be adjusted on the long ladder 1, thereby achieving more accurate detection.

[0037] Additionally, a loudspeaker can be installed on ladder 1 to emit a warning sound.

[0038] In the preferred embodiment, the lifting track 2 includes a track body 201, a T-slot 204 is provided on the front side of the track body 201, and a lifting rack 206 and a fall-prevention ratchet 207 are provided on the inner wall of the top of the T-slot 204.

[0039] Furthermore, both the first lifting mechanism 30 and the second lifting mechanism 40 include an outer shell 301 with one side open. Two sliding wheel sets 302 are symmetrically arranged on the open side. The two sliding wheel sets 302 are slidably engaged with the left and right ends of the transverse groove above the T-slot 204, respectively. The outer shell 301 is provided with a lifting gear mechanism 303 and an anti-fall pawl 304 that engage with the lifting rack 206 and the anti-fall ratchet 207 respectively through the open side. Specifically, the sliding wheel set 302 is slidably connected to the inner wall opposite to the lifting rack 206.

[0040] This design utilizes the connection between the sliding wheel assembly 302 and the lifting gear mechanism 303 to achieve lateral limitation, allowing it to move only along the vertical direction of the lifting track 2. Simultaneously, the lifting gear mechanism 303, in conjunction with the lifting rack 206, controls its lifting and lowering. Furthermore, the anti-fall pawl 304, when engaged with the anti-fall rack 207, prevents it from falling under gravity, effectively fixing its height. Moreover, it effectively forms a wraparound structure, providing effective protection for its main structure.

[0041] In a preferred embodiment, the lifting gear mechanism 303 includes a rotating shaft 3030 rotatably disposed in the housing 301. Specifically, the rotating shaft 3030 is disposed in the housing 301 via bearings. A lifting gear 3031 that meshes with the lifting rack 206 is disposed outside the rotating shaft 3030. A drive device 3032 is disposed outside the housing 301. One end of the rotating shaft 3030 extends out of the housing 301 and a synchronous transmission assembly 3033 is disposed between it and the output shaft of the drive device 3032. In this embodiment, the synchronous transmission assembly 3033 is a chain and sprocket structure, and the drive device 3032 is a transmission combination structure of a motor and a reducer.

[0042] With this design, the drive device 3032 can be used to control the rotation of the lifting gear 3031, thereby using the rotation of the lifting gear 3031 on the lifting rack 206 to control its lifting effect.

[0043] It should be noted that in the first lifting mechanism 30, the driving device 3032 is located on the top of the housing 301, and in the second lifting mechanism 40, the driving device 3032 is located on the bottom of the housing 301, so as to adapt to the arrangement position of the respective cameras.

[0044] In the preferred embodiment, the synchronous transmission component 3033 is externally fitted with a protective cover 3034, which can provide a certain degree of protection for the synchronous transmission component 3033.

[0045] In the preferred embodiment, the anti-fall pawl 304 includes a support plate 3040 vertically disposed in the outer casing 301. A pawl 3041 is rotatably disposed on the side of the support plate 3040. A rear bearing is disposed on the support plate 3040. The pawl 3041 is rotatably connected to the bearing via a shaft. A baffle 3042 is disposed on the side of the support plate 3040 behind the pawl 3041. A spring plate 3043 is installed on the baffle 3042 that abuts against the back of the pawl 3041. The spring plate 3043 can be used to abut the pawl 3041 against the anti-fall pawl 207. When the pawl 3041 is engaged with the anti-fall pawl 207, the upper detection mechanism 3 or the lower detection mechanism 4 can be prevented from falling.

[0046] This design achieves unidirectional limiting of the first lifting mechanism 30 and the second lifting mechanism 40. At the same time, when moving upward, it can be directly driven by the lifting gear mechanism 303, and it also avoids the situation of falling during the movement.

[0047] It should be noted that both the fall arrestor pawl 304 and the fall arrestor pawl 207 are commercially available products, so no further explanation will be provided here.

[0048] Furthermore, in order to enable the first lifting mechanism 30 and the second lifting mechanism 40 to move downward, the tail end of the pawl 3041 is also provided with an extension plate 3044, the end of the extension plate 3044 is provided with a block to be attracted 3045, the inner wall of the outer shell 301 is provided with a mounting seat 3046, and the end of the mounting seat 3046 is provided with an electromagnet 3047 corresponding to the block to be attracted 3045.

[0049] With this design, the electromagnet 3047 can be used to attract the block to be attracted 3045, so that the pawl 3041 can be disengaged from the anti-fall ratchet 207, thereby releasing its one-way limiting function and realizing the descent function. At the same time, after the descent is completed, the pawl 3041 can be reset by releasing the attraction state to achieve the fixed position.

[0050] In the preferred embodiment, the sliding wheel assembly 302 includes a wheel seat 3020 located in the T-slot 204. The wheel seat 3020 is elongated, and rollers 3021 are rotatably provided at both ends of the wheel seat 3020. The rollers 3021 are slidably connected to the inner wall surface opposite to the lifting rack 206, thereby playing a lateral limiting function without affecting vertical movement.

[0051] In the preferred embodiment, a cable groove 203 is also provided on the rail body 201. The cable groove 203 facilitates the arrangement of corresponding lines. A connecting groove 205 is also provided between the cable groove 203 and the T-shaped groove 204. The connecting groove 205 facilitates the connection between the lines and the corresponding equipment. The lifting rack 206 and the anti-fall ratchet 207 are located on both sides of the connecting groove 205.

[0052] In the preferred embodiment, the back of the rail body 201 is also provided with a pipe clamp 202 for fixing to the guardrail, and the pipe clamp 202 is a commercially available product.

[0053] Additionally, it should be noted that the electronic control system in this embodiment adopts the corresponding existing technology, so it will not be described in detail here. The network comes from the wind farm network (wireless network covers the wind farm) and is used to transmit real-time images.

[0054] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
