[0038] In addition, the distance between the hanging points of the first safety rope 1 and the second safety rope 2 can be monitored in real time through the distance detection assembly 3 during the aerial work, so as to timely remind the work personnel when the fixed object of the suspended safety rope is broken or loose.

[0039] Optionally, as shown in Figures 2 to 4 the detection signal of the distance detection assembly 3 is a magnetic field signal, the signal transmitting device is a strong magnetic sheet 31, and the signal receiving device is a Hall sensor 32.

[0041] In other embodiments, the detection signal of the distance detection assembly 3 can also be a light signal, an ultrasonic signal or an electromagnetic wave signal, as long as the detection of the distance can be realized.

The fixed object can be a bearing steel beam, an equipment frame or other fixed structures with bearing capacity, so as to ensure the safety of the work personnel.

[0043] In some embodiments, the safety belt device 100 further comprises a control device and an alarm device, and the signal receiving device and the alarm device are electrically connected with the control device.

[0048] The Hall sensor 32, the buzzer 41 and the time switch 42 are connected with the control device, the Hall sensor 32 is used for detecting the distance from the strong magnetic sheet 31 and transmitting the detected distance value to the control device, and the time switch 42 is used for timing the holding time of the distance signal, when the distance value detected by the Hall sensor 32 is lower than the preset distance value and the holding time exceeds the preset time, the control device controls the buzzer 41 to start the alarm to remind the operator to adjust the suspension points of the first safety rope 1 and the second safety rope 2.

[0049] For example, the preset distance value is 12 cm and the preset time is 2 min, when the distance value detected by the Hall sensor 32 is less than 12 cm and the time switch 42 timing exceeds 2 min, the buzzer 41 alarms.

[0060] Through the above arrangement, the detachable connection of the first mounting seat 5 and the first safety rope 1, and the detachable connection of the second mounting seat 6 and the second safety rope 2 can be realized; in other words, at the end of the aerial work, the Hall sensor 32 and the strong magnetic sheet 31 can be detached and stored separately, so that the risk of damage of the Hall sensor 32, the time control switch 42 and other electrical components during storage and transportation is reduced.

[0061] Specifically, as shown in FIG. 6, the first clamping piece 72 and the second clamping piece 73 are both in a strip shape, and the length direction of the first clamping piece 72 and the length direction of the second clamping piece 73 are consistent with the length direction of the connecting seat 71. Figure 3 and Figure 4As shown, the number of connecting assemblies 7 and driving assemblies 8 is both two, the driving assemblies 8 correspond to the connecting assemblies 7 one by one, and are respectively used for controlling the two connecting assemblies 7 to switch between the clamping mode and the loosening mode; the two connecting assemblies 7 correspond to the first mounting seat 5 and the second mounting seat 6 respectively, so that the first mounting seat 5 and the second mounting seat 6 can be detached.

[0062] In some embodiments, the driving assembly 8 includes a bidirectional screw 81, a first sliding block 82 and a second sliding block 83, the first sliding block 82 and the second sliding block 83 are both slidably connected with the connecting seat 71, the bidirectional screw 81 is rotatably connected with the connecting seat 71, the bidirectional screw 81 has a first threaded section and a second threaded section with opposite screw directions, the first sliding block 82 is sleeved on the first threaded section and threadedly matched with the first threaded section, the second sliding block 83 is sleeved on the second threaded section and threadedly matched with the second threaded section, the first clamping piece 72 is connected with the first sliding block 82, and the second clamping piece 73 is connected with the second sliding block 83.

[0064] As shown in the figure, Figure 3 The connecting seat 71 is fixedly connected with the side of the seat body 52 of the first mounting seat 5 away from the cover plate, the connecting seat 71 has a sliding groove 711, the first sliding block 82 and the second sliding block 83 are both slidably matched in the sliding groove 711, so as to limit the first sliding block 82 and the second sliding block 83 to slide along the length direction of the first mounting seat 5; the bidirectional screw 81 is arranged in the sliding groove 711 and extends along the length direction of the sliding groove 711, both ends of the bidirectional screw 81 are rotatably arranged on the two side walls of the sliding groove 711, so as to realize the rotation support of the bidirectional screw 81; the first sliding block 82 and the second sliding block 83 are both sleeved on the bidirectional screw 81, the first threaded section of the bidirectional screw 81 is slidably matched with the first sliding block 82, and the second threaded section of the bidirectional screw 81 is slidably matched with the second sliding block 83, the relative movement of the first sliding block 82 and the second sliding block 83 can be controlled by controlling the rotation of the bidirectional screw 81, and then the relative movement of the first clamping piece 72 and the second clamping piece 73 is controlled, so that the connecting assembly 7 is switched between the clamping mode and the loosening mode.

[0065] The end of the bidirectional screw 81 close to the Hall sensor 32 penetrates through the side wall of the connecting seat 71, and the knob 84 is connected, the outer surface of the knob 84 has anti-skid lines, and the rotation of the bidirectional screw 81 can be manually controlled by using the knob 84, and the operation is more convenient.

[0066] Similarly, as shown in the figure, Figure 4As shown, the connecting seat 71 is fixedly connected with the second mounting seat 6, and the first clamping piece 72 and the second clamping piece 73 can be controlled to relatively approach or relatively move away along the length direction of the second mounting seat 6 by the bidirectional screw rod 81, so as to clamp or release the second safety rope 2.

[0067] Optionally, the thread angle of the bidirectional screw rod 81 is smaller than the friction angle, so that the bidirectional screw rod 81 has self-locking capability, and the first clamping piece 72 and the second clamping piece 73 are prevented from relatively moving away under external force during the aerial work, the stability of clamping is improved, and the accuracy of distance detection is further improved.

[0068] In some embodiments, the first clamping piece 72 and the second clamping piece 73 both have oppositely arranged arc-shaped grooves, and the arc-shaped grooves of the first clamping piece 72 and the arc-shaped grooves of the second clamping piece 73 form a clamping groove when the connecting assembly 7 is in the clamping mode.
