Description

A high-rise circulation escape device

technical field

The invention relates to the technical field of high-rise escape equipment, in particular to a high-rise circular escape device.

Background technique

Today, when the safety awareness is getting stronger and the floors are getting higher and higher, the problem of escape from high-rise buildings has become a problem that is not easy to solve but cannot be ignored. At about 9:17 on November 5, 2010, Chuanying District, Jilin City, Jilin Province A fire broke out in a commercial building, killing 19 people and injuring 24 people who were hospitalized. It is understood that the shopping mall has five floors and a construction area of about 42,000 square meters. We operate bedding, bags and bags on the fifth floor, part of which is a children's playground, and the fire department is located on the first floor. All fires on the first to fourth floors, and partial fires on the fifth floor. There are many floors in high-rise buildings, and the evacuation distance is long, resulting in a corresponding change in the time spent. It is long, and it is difficult to concentrate and evacuate people, and it is easy to cause heavy casualties; in addition, most cities with high-rise buildings do not have climbing fire trucks. Even if there are, the height is not enough to meet the needs of safe evacuation, and climbing is difficult. If there is no special fire elevator or the fire elevator fails, the firefighters can only walk upstairs to rescue from the stairs. Not only will they "collide" with the evacuated crowd, which will affect the rescue efficiency, but also limited by physical factors. After climbing a certain height on foot, The heart rate and breathing speed up, and the physical strength decreases, which is not conducive to carrying out fire fighting and rescue activities. Most of the existing high-rise escape devices can only be used once, the rescue interval is long, and the rescue efficiency is too low. Safety cannot be effectively guaranteed.

Contents of the invention

The technical problem to be solved by the present invention is to provide a high-rise circular escape device with simple structure and strong practicability, so as to overcome the deficiencies of the prior art.

The present invention is achieved like this:

A circular escape device for high-rise buildings, including a circular escape device body, characterized in that: the rope rotation axis is fixed in the cycle escape device body, the rope used for escape is fixed on the rope rotation shaft of the cycle escape device body, and the rotation axis of the rope is The bottom circular escape body is provided with an installation groove, and the spring support is installed in the installation groove and fixed. The top of the spring support is fixed on the bottom side of the rope rotation shaft to realize the control of the rope rotation axis on the spring support. It can move up and down, and the rope rotator is connected with the drive motor through the reducer. A rope guide port is set at the bottom of the circulation escape body and the rope is led out from the rope guide port. Spring or hydraulic support rods are symmetrically arranged on both sides of the guide port. The tail of the spring-type support rod is respectively hinged on both sides of the guide port, a rubber pad is arranged at the end of the spring-type support rod and the end of the spring-type support rod is closely attached to the side wall of the rubber pad, and the rubber pad is covered on the rope on the top of the rope, and set round knots at intervals at the end of the rope, and at least two stages of reducer are installed in the body of the circulation escape device. The motor drives the reducer to rotate, and a concentric disc is set on the side of the driving gear. A fixed shaft is set on the working end surface of the disc and the fixed shaft is located on the side of the disc axis. At least one end of the air pressure device is sleeved on the fixed shaft. , the other end is hinged on the bracket of the circular escape body around the disc, at least two spring grooves are set on the working end surface of the disc and the spring grooves are symmetrical to the center of the disc, the spring grooves are radially distributed, and the springs are installed In the spring groove, one end of the spring is fixedly connected to the central axis of the disc, and the other end is connected to the mass body. A friction groove is provided directly above the side of the disc, and the friction groove corresponds to the position of the mass body. When the rope descends almost to the ground, the circular knot will rub against the rubber pad and the circular knot will move in sequence in the rubber pad. During this process, the kinetic energy of the escape personnel will be reduced by friction, and the spring support rod will also shrink. And part of the kinetic energy of the personnel is converted to the kinetic energy of the spring-type support rod. When the spring-type support rod rotates, the spring-type support rod can rotate because the spring-type support rod is hinged. When designing, the maximum The size of the rotation angle cannot make the spring-type support rod perpendicular to the rope. When the spring-type support rod rotates, the end of the spring-type support rod will compress the rubber pad, so that the clearance size of the rubber pad becomes smaller, so that it can be connected with the next circular knot. During the contact process, the mutual friction force is further increased, so as to complete the deceleration of the rope of the circular escape device. By setting the spring support to rotate with the rope, when the whole device is not stressed, the compression spring stretches out, and the rope rotates axially. Push up, so that the gear on the rope rotation shaft does not mesh with the gear in the reducer, causing the reducer to fail, so that the rope can be bounced back faster by the scroll spring. When an escape person pulls the rope escape rope, Relying on the escape personnel's own gravity, the spring support is compressed to make the gears mesh, and the drive motor drives the rope to transport and descend at a specific speed, so as to achieve the goal of transporting escape personnel. Function, the mass body and the friction groove cooperate to realize the control of the speed of the driving gear, and the air pressure device can effectively avoid the secondary injury to personnel caused by the stall of the driving gear.

In the aforementioned high-rise circulation escape device, a coarse compression spring is arranged under the rope guide opening, and the coarse compression spring is fixed on both sides of the coarse compression spring by connecting the connecting rod with the circulation escape device body, and the rope penetrates into the coarse compression spring and A clamping plate is set at the bottom of the coarse compression spring. By setting the coarse compression spring, a buffer occurs when the rope returns to its position, which effectively prevents the rope from being directly stuck into the circular escape device due to excessive speed during the return process.

In the aforementioned high-rise circular escape device, a handle is provided at the tail end of the rope. By setting the handle, it is not only convenient for the escape personnel to hold the rope, but also the handle cooperates with the clip on the thick compression spring, so that the rope can be moved back to its original position. Return to the original set position.

In the above-mentioned high-rise circular escape device, a plane scroll spring is fixed on the rope rotation shaft, and the working end of the plane scroll spring is fixed at the end of the rope used for escape. Unlike ordinary springs, the scroll spring can only be compressed in the lateral direction. And elongation, which has the characteristic of being stretchable in the radial direction, one end of the scroll spring is connected with the bobbin and fastened, and the other end is connected with the wire rope. When there is an escaper who is practical, because its gravity is greater than the elastic force of the scroll spring, it can descend and escape smoothly; when the escaper reaches the ground safely and releases the safety rope, because the force disappears, the scroll spring resumes its function, which can make the escape The safety rope bounces back quickly, ready for the safe escape of the next survivor.

In the aforementioned high-rise circular escape device, bearings are arranged on both sides of the rope rotating shaft, and a moving groove is arranged at a corresponding position of the circular escape device. The bearing is embedded in the moving groove of the circular escape device. Fixed connection, by setting the moving groove, the rope rotating shaft can move up and down quickly in the moving groove, so as to achieve the effect of quickly engaging and separating from the reducer.

In the aforesaid circulating escape device for high-rise buildings, a ventilation groove is arranged on the inner wall of the sealed cylinder.

In the aforesaid high-rise circular escape device, a spacer is provided in the spring groove, the lower end of the spacer is pressed against the central shaft, and the upper end of the spacer forms a clamping platform with the spring groove, and the radial limit of the mass body is realized by setting the spacer. bit.

In the aforesaid circulating escape device for high-rise buildings, the mass body includes an inertial body and a connecting rod arranged at the lower end of the inertial body. In the groove, the cross section of the inertial body is a trapezoidal structure. A rubber block is arranged on the upper end of the inertial body and the rubber block is matched with the friction groove. Great friction.

Due to the adoption of the above technical solution, compared with the prior art, the present invention reduces the kinetic energy of the rope through the sliding friction of the circular bonded rubber pad, and at the same time, by setting the spring-type support rod, part of the kinetic energy of the rope can be converted into a spring-type support rod. The potential energy of the support rod is stored to effectively decelerate the rope. By setting the scroll spring at the end of the rope, after the escape is completed, the rope can quickly return to its position by relying on the potential energy stored in the scroll spring itself, which greatly saves the escape Time, by setting the spring support part 1, the rope rotation shaft and the reducer can be quickly engaged or separated, which is conducive to the uniform descent or rapid recovery of the rope, and the drive of the rope rotation shaft can be realized through the motor-driven reducer. The air pressure device realizes the control of the speed of the driving gear, avoiding the de-control of the speed caused by the imbalance of the driving motor, which will cause secondary damage to the escaped persons. By setting a center-symmetrical mass block on the disc, the mass block is fixed by a spring. During the rotation of the disc, if the rotating speed is too fast, the mass block will move outward against the tension of the spring, and the mass block will rub against the friction groove, so as to realize the deceleration of the disc. Recycling, the mass block is separated from the friction groove, the invention has simple structure, convenient manufacture and strong practicability.

specific use

The spring tension in the spring support rods of this embodiment is 369.2N, the deceleration device is mainly composed of a circular knot, a spring support rod and a thick compression spring, and the two thin spring support rods are at an angle of 60° with the safety rope, and The end of the thin spring in contact with the safety rope is equipped with a rubber pad (to increase the friction coefficient), the rubber pad ends of the two thin springs are on the same horizontal line, and the two springs are symmetrically distributed.

It works as follows:

The design needs to slow down before landing 6m, so the last 6m of the rope is provided with round knots every half a meter. The diameter of the round knot is slightly larger than the distance between the ends of the two thin spring rubber pads. The diameter of the round knot is 0.8cm. The distance between the ends of the rubber pads is 0.5 cm. When the survivor uses this device to escape, when the distance from the ground is 6m, the round knot contacts the rubber pad ends of the two thin springs, causing friction (loss of potential energy of the rope), and at the same time, the spring-type support rod shrinks to convert the kinetic energy into elastic potential energy, achieving The purpose of decelerating the safety rope is to prevent the survivors from reaching the ground too fast and causing damage. Due to the shape of the node and the angle of the two thin springs, the node can pass through the gap between the two thin springs relatively easily. The length of the safety rope can be fully utilized, and it also has the effect of deceleration. Due to the angular relationship between the two thin springs, the two points at the end of the rubber pad generate a greater squeezing force, which further increases the friction and makes the safety rope start to slow down. When reaching the ground, the speed is about 1m/s. When the first escaper reaches the ground safely, he releases the handle. Since the safety rope is no longer subject to the gravity of the human body and is only controlled by the circular escape device, the safety rope begins to return to the ground. position, when the handle reaches the initial position, due to the effect of the buffer device (that is, the thick compression spring, clamp and handle), the speed of the handle can tend to 0m/s in a very short time, at this time the subsequent The survivors can repeat the actions of the previous survivors to escape.

Unlike ordinary springs, scroll springs can only be compressed and stretched in the transverse direction, and have the characteristics of being stretchable in the radial direction. One end of the scroll spring is connected to the bobbin and fastened, and the other end is connected to the wire rope. When there is an escaper who is practical, because its gravity is greater than the elastic force of the scroll spring, it can descend and escape smoothly; when the escaper reaches the ground safely and releases the safety rope, because the force disappears, the scroll spring resumes its function, which can make the escape The safety rope bounces back quickly to prepare for the safe escape of the next escapee. When the whole device is not stressed (that is, after the first escapee reaches the ground), the compression spring stretches out to rotate the rope on the shaft. The gears of the gear and reducer do not mesh, causing the reducer to fail, which allows the rope to bounce back faster by the scroll spring.

Rope recovery link: the gear on the rope rotating shaft is not meshed with the gear of the reducer, so that the speed controller can be separated from the left half, which will not affect the speed and efficiency of rope recovery, but the drive motor and The reducer is working, and the cylinder and the speed controller will stop working when the rope is recovered.

The principle of rope recovery is: the whole lifesaving rope starts with a steel tape measure. The principle design is a strip of stainless steel sheet, the width of this strip is 4cm, and the material of the last 6m is rope. The diameter is smaller than the distance between the two outer springs but larger than the distance between the two inner springs. Its purpose is to reduce the speed at which the rope shrinks. The last baffle and the outer spring play a buffer role.

Turn on the driving motor, the driving motor drives the driving gear to rotate, and the air pressure device controls the driving gear. When the driving motor is out of balance or the escaped person returns to drive the driving gear to stall due to excessive weight, ensure that the speed of the driving gear is kept at a reasonable state, thereby effectively avoiding Cause secondary damage to the escaped personnel.

It works as follows:

The reducer part has two stages of acceleration, each acceleration multiple is 2.4 times, and the total acceleration is 5.76 times. The rope rotating shaft is connected with the driving gear through the reducer, and the crankshaft located on the driving gear disc makes a circular motion. The pistons are connected, and the circular motion is then transformed into a linear motion.

This embodiment adopts the principle of fluid damping. If a spring is used as the resistance, according to Hooke's theorem, the resistance is related to the displacement of the drop. The greater the displacement, the greater the resistance. Uniform purpose. Due to the relatively long time during friction, the friction coefficient will fluctuate and the performance will not be stable. The gas flow damping type uses gas flow damping to convert the gravitational potential energy of the human body into the heat energy of the gas, which can reduce the speed. Since the size of the gas damping depends on the external load, it can descend at a relatively constant speed regardless of the mass of the human body (the design descending speed is 2.5m/s).

The inner diameter of the liquid cylinder is 3.5cm, the outer diameter is 4cm, the height of the liquid cylinder is 4.5cm, the range of motion of the piston is 4cm, and the length of the connecting rod is 4.5cm. The cross-sectional area of the cylinder is 9.61cm2, because there is a ventilation groove between the cylinder inner wall and the piston, so the area of the piston is determined as 9.60cm2.

The cylinder used in this escape machine is similar to an ordinary piston cylinder. The difference is that both ends of the cylinder are sealed, and there is a certain amount of gas inside for damping. There is a ventilation groove between the piston and the wall of the cylinder. Rubber bowl. When the piston is pulled up, the volume of the air below the piston increases and the pressure decreases, and the air above the piston is squeezed from around the rubber bowl to the bottom. When the piston is pressed down, the volume of the air below the piston decreases and the pressure increases , so that the rubber bowl is tightly pressed against the wall of the cylinder to prevent air from leaking above the piston, and continue to press down on the piston, so that resistance is generated to make the speed change tend to be even and stable, and it has a buffering effect. According to the knowledge of fluid mechanics, such a design is conducive to achieving the purpose of uniform velocity. According to calculations, a person of 70kg (average weight of Chinese women: 56.70kg, average weight of Chinese men: 65.77kg) just slides down at a constant speed of 2.5m/s. One end of the piston is connected with the crank rocker. In this way, the rotary motion of the crank is converted into the linear motion of the piston, and the energy is converted into heat energy and kinetic energy of the fluid by means of the fluid. This design has two cylinders whose positions are at an angle of 90°.

Adopting such a structural design not only reduces the load force borne by a single cylinder, but also makes the size of the cylinder not too large, so that the internal structure of the escape machine is more rationalized. At the same time, it also effectively solves the problem that the speed of the crank is easy to fluctuate when it rotates to the limit position. The multi-stage transmission of the acceleration part can effectively solve the problem of easy fluctuation of speed, and make the falling speed more stable.

The speed controller of this embodiment is the core link of the device. Although the structure of this part is relatively simple, it is very practical and can automatically control the speed at 2.5m/s.

It is mainly composed of: grooved disc, centrifugal block, spring and friction groove. Its structure is shown in the attached figure:

The disc radius is 7cm, the spring stiffness coefficient is 351.1N/m, and the mass of each mass body (including the inertial body and connecting rod) is 18g. When the speed is 2.5m/s, F(r=7cm)=94.95N.

There are three guide grooves evenly distributed on the grooved disc, and there is a mass block in each slot. The mass block can move linearly along the radial direction while doing circular motion. One end of the mass block is connected to the central axis of the disc with a spring. , The contact end of the quality block and the friction groove is equipped with a trapezoidal rubber block whose shape matches the friction groove, and the increase of the speed is prevented by increasing the friction force.

Speed controller principle: centrifugal principle

analyze:

1. When the disc is at rest

The spring is in the natural length without tension, and the resistance of the switch valve is 248.84N, and the mass block does not move outward at this time.

2. When the disc rotates

The mass has a tendency to fly away. With the increase of the rotating speed of the disc, the centrifugal force also increases. When the rotating speed of the disc reaches 2039r/min, the centrifugal force of the mass is just greater than the resistance of the switching valve. After the connecting rod of the switching valve swings outward, the mass The pressure of the block changes from inside to outside, further increasing the friction, causing the disc to decelerate rapidly, and the spring is now in tension. When the descending speed is reduced to 2.5m/s, the resultant force of the centrifugal force of the mass block and the connecting rod is less than the tension of the spring, the spring contracts, the mass block is pulled back to the inside, and the mass block returns to its original state. If the speed of the disc increases again, the connecting rod will open again, and the mass block will decelerate it again, and so on, the speed of the disc will be controlled at 2.5m/s to achieve the purpose of steady speed.

The description of the above solution is an invention for those of ordinary skill in the technical field to understand and use. Various modifications to the embodiments will be apparent to those skilled in the art. Therefore, the present invention is not limited to the above-mentioned practical solution, and improvements and modifications made by those skilled in the art according to the method of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
