Fig. 1 shows a schematic structural diagram of an aerial work safety belt provided by the invention.
As shown in fig. 1, in the aerial work safety belt safety rope locking device, the safety belt 1 is connected with a connecting rod 3 through a connecting buckle 2, one end of the connecting rod 3 far away from the connecting buckle 2 is provided with a locking device 4, one end of the locking device 4 far away from the connecting rod 3 is provided with a safety rope 6, and one end of the safety rope 6 far away from the locking device 4 is provided with a fixer 5. Two safety cords 6 are often used for safety.
Fig. 2 shows a schematic structural view of the lock device 4 provided by the present invention, and fig. 3 shows a schematic structural view of internal components of the lock device 4.
As shown in fig. 2 and 3, the locking device 4 includes a protective upper casing 41 and a protective lower casing 42, the protective upper casing 41 and the protective lower casing 42 constitute a closed casing, and the closed casing includes a roll-up drum 51, a rotating rod 52, a bracket 53, a ratchet 54, a lock lever 55, a spiral spring 56, a turntable 57, a motor 58 and a power supply 59. The winding drum 51 is used for winding the safety rope 6 on the winding drum 51 to realize the winding of the safety rope 6; the rotating rod 52 penetrates through the inside of the winding drum 51 and is rigidly connected with the winding drum 51, so that the rotating rod 52 and the winding drum 51 synchronously rotate, the rotating rod 52 is erected on the protective lower shell 42 through the brackets 53 arranged at two sides of the rotating rod 52, and the winding drum 51 is positioned in the middle of the brackets 53.
One end of the rotating rod 52 is connected with the ratchet wheel 54, and a lock rod 55 is arranged above the ratchet wheel 54; the other end of the rotating rod 52 is connected with the scroll spring 56, the inner end of the scroll spring 56 is connected to the rotating rod 52, the outer end of the scroll spring 56 is connected with a rotating disc 57, the rotating disc 57 is connected to a load shaft of the motor 58, and a power supply 59 is arranged below the motor 58.
The middle position of one side wall of the upper protective shell 41 is provided with two circular openings 43, and the number of the circular openings 43 is two, so that the use of two safety ropes 6 is met. The inner end of the safety rope 6 is fixed on the retractor 51, and the outer end of the safety rope 6 extends out of the shell through the round opening 43 to be fixedly connected with the fixer 5. In this embodiment, the inner diameter of the circular opening 43 is larger than the outer diameter of the safety cord 6, so that the safety cord 6 can easily pass through the circular opening 43.
The ratchet wheel 54 and the lock rod 55 are positioned in a first shell 61, and the lock rod 55 is fixed on the first shell 61 through a connecting rod 62; the scroll spring 56 and the dial 57 are located within a second housing 63. The first case 61 and the second case 63 are protective.

When the upper protective casing 41 and the lower protective casing 42 are connected, gaps are reserved between the inner side wall of the upper protective casing 41 and the first casing 61 and between the inner side wall of the upper protective casing 41 and the motor 58, so that friction between the upper protective casing 41 and the first casing 61 and between the upper protective casing 41 and the motor 58 is avoided.
The corners of the first bump 44 and the second bump 45 are both arc-shaped structures, so as to avoid damage to human bodies when operators contact the structures.
Fig. 4 shows a schematic structural diagram of a cross section in a-a direction in fig. 3, fig. 5 shows a schematic structural diagram of a ratchet wheel and a lock rod in the locking device, and the working principle and the using process of the locking device provided by the present invention are specifically described below with reference to fig. 4 and fig. 5:
when the safety belt fixing device is used by an operator, the safety belt 1 is firstly bound at the correct position of the body, then the connecting buckle 2 on the connecting rod 3 is buckled on the safety belt 1, the fixer 5 at one end of the safety rope 6 is held by a hand, when the safety belt fixing device climbs to the high altitude needing operation, the fixer 5 is fixed at a certain fixable place, and then the high altitude operation is carried out. If the safety rope 6 falls in case of emergency in the process of high-altitude operation, the pulling-out speed of the safety rope 6 is too high, namely the rotation speed of the winding drum 51 is driven to be too high, meanwhile, the rotation speed of the rotating rod 52 is too high, the ratchet wheel 54 rotates under the action of the rotating rod 52 to trigger the pawl above the ratchet wheel 54, the pawl upwarps and contacts the lock rod 55, the ratchet wheel 54 is prevented from continuously rotating through mechanical force, and therefore the safety rope 6 is locked when being suddenly stressed, and the purpose of protecting the safety of high-altitude operation personnel is achieved. In the locking process, if the high altitude construction personnel think that safety rope 6 ties excessively tightly, accessible button (not drawn in the figure) starter motor 58 (power 59 is the circular telegram power supply of motor 58), motor 58 drives carousel 57 and rotates, adjusts volute spiral spring 56's elasticity degree through carousel 57, makes bull stick 52 rotate through adjusting volute spiral spring 56, can be with the elasticity degree of adjusting safety rope 6, avoids the high altitude construction personnel to be tied excessively tightly, improves use comfort. When the inertia is over or disappears, the ratchet wheel 54 rotates reversely under the action of gravity and is vertical to the ground, the pawl is pulled down to be separated from the lock rod 55, and therefore after a small section of the safety rope 6 is retracted backwards, the safety rope can be pulled at a constant speed, and the using effect is good. When using a period of time to need overhaul locking device's inside device, split bolt 64 earlier makes first mounting hole 48 and second mounting hole 49 separately, and spacing pole 47 and spacing hole 48 are separated again, take off protection upper housing 41, then can overhaul the operation to the device of protection lower housing 42 on, guarantee the integrity of inside device, improve the safety in utilization.
It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim.
