The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
The present application will be described in further detail with reference to the accompanying drawings.
Example 1:
as shown in fig. 1, 2 and 3, the high-rise falling emergency rescue device comprises a base 1. The base 1 and the wall 2 are fixedly installed by a fastener or other fixed connection modes. A bracket 3 is arranged on one side of the base 1. The middle part of the bracket 3 is hollow, and the middle part of the bracket 3 is provided with a hinging rod 4. The hinge rod 4 is used as an axis, and a cantilever 5 is rotatably arranged on the hinge rod 4. The middle part of the cantilever 5 is provided with a connecting groove 6. A fall-preventing net (not shown in the figure) is connected in the connecting groove 6. The anti-falling net can also be other objects used for rescue, such as an anti-falling soft cushion.
The bracket 3 is provided with a lock hole 7 at one side of the hinge rod 4. Correspondingly, one side of the cantilever 5 is provided with an unfolding lock catch 8. When the cantilever 5 rotates to be perpendicular to the base 1 (i.e. the unfolded state), the unfolding lock catch 8 on the cantilever 5 is clamped into the lock hole 7 to complete locking, so that the cantilever 5 is fixed when unfolded. Meanwhile, a furling lock catch 9 is arranged on one side of the bracket 3. The folding lock catch 9 penetrates into the bracket 3, and one side of the lower end is abutted with the cantilever 5 to prevent the cantilever 5 from being automatically unfolded.
An unfolding spring 10 is obliquely arranged between the cantilever 5 and the base 1. The unwinding spring 10 is used to control the cantilever 5 to rotate to be perpendicular to the base 1 so that the cantilever 5 is opened.
The unfolding lock catch 8 and the folding lock catch 9 are electromagnetic lock catches, and the opening and closing of the unfolding lock catch and the folding lock catch can be controlled by means of sensors and the like.
The position of the anti-falling device installed on the house and the position of the sensing device 11 according to the present application are shown in fig. 3.
The working process comprises the following steps:
the two sides of the house, which are close to the ground, are respectively provided with the high-rise anti-falling device, and the two high-rise anti-falling devices are jointly connected with the two sides of the same anti-falling net. Meanwhile, an induction device 11 is arranged at a higher position of the floor, and the induction device 11 can induce falling staff to pass through the induction device 11 and can transmit information to control the folding lock catch 9. The sensing means 11 described above is preferably an infrared sensor.
When the sensing device 11 receives the information, the folding lock catch 9 can be enabled to work, and the folding lock catch 9 moves upwards to enable the lower end of the folding lock catch 9 to be far away from the cantilever 5, so that the folding lock catch is not abutted against the cantilever 5 any more. At this time, the cantilever 5 is swung by the expanding spring 10, and the cantilever 5 is swung open to be in a vertical state with respect to the base 1. At this time, one side of the cantilever 5 is abutted against the bracket 3, and the unfolding lock catch 8 is clamped into the lock hole 7 to fix the position of the cantilever 5. At this time, the two cantilevers 5 are unfolded, so that the falling prevention net is opened, and falling staff fall on the falling prevention net to obtain buffering, thereby reducing injury to the falling staff.
Example 2:
as shown in fig. 4 and 5, the difference from embodiment 1 is that the expanding spring 10 is not provided between the bracket 3 and the base 1, the locking hole 7 is not provided on the bracket 3, and the expanding latch 8 is not provided on the cantilever 5. The bracket 3 is provided with a hollow groove 12 corresponding to the cantilever 5 rotating to a position vertical to the base 1. Meanwhile, one end of the hinging rod 4 is rotatably connected with the bracket 3, and the other end of the hinging rod penetrates through the empty groove 12 and is connected with the water storage tank 13. In the above initial state, the folding latch 9 locks the cantilever 5.
The hinge rod 4 is sleeved with a driving spring 14, one end of the driving spring 14 is connected with the bottom of the cantilever 5, and the other end is connected with an extrusion plate 15. When cantilever 5 rotates to be perpendicular with base 1, cantilever 5 will prevent weighing down the net and open, if fall on the cantilever 5, make cantilever 5 move down along articulated rod 4, drive spring 14 compression simultaneously, exert certain cushioning effect to falling the produced impact force of building personnel weight on the weighing down net, also can reduce cantilever 5, support 3 and the impact force that receives on the base 1 simultaneously, prevent to connect unstable and lead to above-mentioned part pine.
In the initial state, the driving spring 14 is in a torsion state and has a certain torsion elasticity, so that the driving spring 14 can conveniently drive the cantilever 5 to rotate.
As shown in fig. 6 and 7, the water storage tank 13 is filled with liquid water, and a buffer tank 16 is provided in the middle. The water storage tank 13 is provided with a protective groove 17 communicated with the buffer groove 16 on both sides. When the anti-falling net is not opened, the cantilever 5 is parallel to the base 1, and the squeeze plate 15 is located at the position shown in fig. 6. When the extrusion plate 15 is impacted by the weight of a person falling down the building, the cantilever 5 moves downwards, so that the extrusion plate 15 is driven to move downwards to extrude the water in the water storage tank 13, the water flows to the protection grooves 17 at the two sides, and the liquid level in the protection grooves 17 rises. The buffering through liquid water and the double buffering action of the driving spring 14 reduce the impact of falling staff on the anti-falling net and reduce the physical injury to falling staff.
Preferably, both sides of the top of the water storage tank 13 are respectively provided with a chute 18 communicated with the protective groove 17. A piston plate 19 is slidably provided in the chute 18. At least two obliquely arranged protection plates 20 are connected to one end of the piston plate 19. Wherein, a buffer spring 21 is arranged between the piston plate 19 and the protection plate 20. The guard plate 20 can be made of metal or strong rubber, and the top is provided with the fillet 22, prevents the impact damage with the guard plate 20 when the stripper plate 15 kick-backs.
As described above, when water is pressed by the pressing plate 15, the water pressure rises, thereby pushing the piston plate 19 to move outward and simultaneously driving the shielding plate 20 to move to the exit chute 18. When falling staff falls on the falling-preventing net to cause the falling-preventing net to move downwards to the bottommost end along with the cantilever 5, the driving spring 14 has a reverse resilience force due to larger impact force on the water storage tank 13, so that the falling staff is prevented from being popped out of the falling-preventing net due to larger resilience force, the scheme is designed, and the resilience of the extrusion plate 15 can be reduced when the extrusion plate 15 rebounds through the protection plate 20
Force. When the pressing plate 15 presses the shielding plate 20, the shielding plate 20 is retracted into the chute 18 by the partial compression of the buffer spring 21 by the force of the shielding plate 20, which is decomposed into the force of the shielding plate 20 to move in the longitudinal direction by the upward resilience force of 5, which is obliquely provided. At the same time, the pressing plate 15 continues to abut against the next shielding plate 20, further reducing the resilience of the pressing plate 15. Through the decomposition buffering to resilience many times to prevent great resilience force and lead to falling building personnel to pop out from preventing weighing down the net, reduce falling building personnel's risk of injuring that probably produces.
At the same time, the piston plate 19 is provided with a fixed inclined plate 23 on top of the protection plate 20. Fixing device
The fixed inclined plate 23 plays a termination role, and after the buffering of the protection plates 20, the extrusion plate 15 is finally abutted to the fixed inclined plate 23, so that the process of enabling the extrusion plate 15 to stop rebounding is achieved, the situation that personnel on the falling prevention net are no longer in a vibrating state is ensured, and rescue personnel can rescue falling personnel conveniently.
5 in addition, the adjacent protection plates 20 are mutually abutted, so that a good supporting effect is achieved, friction force between the protection plates 20 is small, mutual obstruction is avoided, movement of a single protection plate 20 drives integral movement, and a good buffering effect is guaranteed.
In addition, the application is also provided with an electromagnetic lock cylinder 24. Corresponding to the electromagnetic lock column 24, a clamping groove 25 is arranged in the middle of the piston plate 19. A pressure sensor can be arranged at the bottom of the water storage tank 13 in a matched manner, and if the impact force is not completely eliminated due to double buffering, the pressure sensor can transmit information to the electromagnetic lock column 24. The electromagnetic lock column 24 moves downwards to penetrate into the clamping groove 25 to complete clamping, the piston plate 19 is positioned, and the return of the piston plate 19 during rebound is prevented, so that the rebound prevention effect of the protection plate 20 is affected. The circuit connection of the electromagnetic lock cylinder 24 is in the prior art, and thus is not described in detail.
The whole working process comprises the following steps:
1. when falling from higher floor, the personnel sense the human body through the induction system 11 on both sides of floor for draw in hasp 9 work, draw in hasp 9 and no longer spacing cantilever 5. Under the action of the torsion driving spring 14, the driving spring 14 drives the cantilever 5 to rotate. When the cantilever 5 rotates to be in a vertical state with the base 1, the anti-falling net is opened;
2. the falling staff falls onto the falling net, and at this time, the falling net receives a great momentum caused by the weight acceleration of the falling staff. At this time, the cantilever 5 connected with the anti-falling net receives pressure so as to move downwards along the empty slot 12, and at this time, the driving spring 14 is compressed to play a certain buffering role;
3. meanwhile, the squeezing plate 15 squeezes the water in the water storage tank 13 under the action of the driving spring 14, so that the water in the buffer tank 16 in the middle flows to the protection tanks 17 on two sides, the water pressure in the protection tanks 17 rises, and the squeezing plate 15 is subjected to the buffer action of the water, so that the momentum brought by falling staff is further reduced;
4. the hydraulic pressure rises so that the piston plate 19 is forced to slip outwards. The piston plate 19 slides outwards to drive the protection plate 20 and the fixed inclined plate 23 to move partially out of the chute 18 along the chute 18 and into the buffer groove 16. At this time, the pressing plate 15 is at the lowest point;
5. since the person falling down the stairs still has a large momentum when the pressing plate 15 moves to the lowest point, the momentum generates a large reaction force, i.e., a reverse resilience force, due to the presence of the water reservoir 13. At this time, the squeeze plate 15 can move reversely, so that falling staff on the falling net can be easily popped up out of the falling net, and the falling staff is damaged;
6. when the extrusion plate 15 rebounds, the protection plate 20 at the lowest position is abutted firstly, so that the protection plate 20 receives pressure and retracts into the chute 18 when decomposing the rebound force, then, the extrusion plate 15 is abutted against the adjacent protection plates 20 in sequence, so that the rebound force is decomposed to an acceptable range, and finally, the extrusion plate is positioned by the fixed inclined plate 23, thereby achieving a stable state and facilitating the rescue of subsequent rescue workers on falling building personnel.
