Description

Technical Field

[0001] The present invention relates to the technical field of intelligent elevators, and in particular to a car top safety protection system for an intelligent elevator. Background Art

[0002] The elevator safety system is a crucial component in ensuring safe elevator operation and protecting passengers and cargo. It encompasses a range of mechanical, electrical, and electronic equipment designed to prevent and address various potential hazards, such as overspeeding, sudden power outages, and unclosed doors. Equipment failures and operator errors can lead to a range of hazards: people being crushed or struck by floor doors or car doors; cars exceeding their travel limits; and wire rope breakage caused by car overspeed or overloading. Preventing these dangerous accidents should be a top priority during elevator design, production, installation, maintenance, and operation. However, safe elevator operation requires not only the structure, the reliability of elevator controls, and timely and effective maintenance, but also specialized protective devices—the elevator safety system—for various potential hazards.

[0003] However, existing smart elevators lack safety protection devices for the top of the car. When objects fall in the elevator shaft, they will impact the top of the car.

[0024] See also Figures 1 to 2The present invention discloses a car top safety protection system 10 for an intelligent elevator, which includes a car body 100, a car top safety protection device 200 and a control device 300. The car top safety protection device 200 and the control device 300 are both installed on the car body 100, wherein the car top safety protection device 200 is arranged on the top of the car body 100, and the control device 300 is electrically connected to the car top safety protection device 200. Therefore, during the operation of the car body 100, the control device 300 can monitor and control the car top safety protection device 200 in real time to realize the safety protection function of the car top safety protection device 200 on the top of the car body 100. Specifically, the car roof safety protection device 200 includes an anti-collision mechanism 210, which is arranged on the top of the car body 100, wherein the anti-collision mechanism 210 is arranged on the outer surface of the top wall of the car body 100, so that the anti-collision mechanism 210 can act as an energy absorption unit to absorb energy of collisions on the top of the car body 100, thereby achieving collision protection for the top of the car.

[0025] Furthermore, the anti-collision mechanism 210 includes an anti-collision plate 211 and an energy-absorbing component. One end of the energy-absorbing component is connected to the outer surface of the top wall of the car body 100, and the anti-collision plate 211 is installed at the other end of the energy-absorbing component. When a collision occurs on the top of the car body 100, the anti-collision plate 211 contacts the impactor and then compresses the energy-absorbing component. During this process, the kinetic energy change generated by the collision is absorbed by the deformation buffer of the energy-absorbing component, thereby effectively reducing the damage to the car body 100 caused by external impact.

[0026] Furthermore, the anti-collision mechanism 210 also includes a support seat 212, and the energy absorption assembly includes a first energy absorption structure 213, a second energy absorption structure 214, two transmission rods 215 and two support rods 216; the support seat 212 is installed on the outer surface of the top wall of the car body 100; the first energy absorption structure 213 is installed on the top side of the support seat 212, and the second energy absorption structure 214 is arranged on the top side of the first energy absorption structure 213 and is movably connected to the support seat 212; the two transmission rods 215 are arranged between the first energy absorption structure 213 and the second energy absorption structure 214; the two support rods 216 are respectively connected to the top side of the second energy absorption structure 214. Specifically, the bottom surface of the anti-collision plate 211 is connected to the top ends of the two support rods 216. Thus, when the anti-collision plate 211 contacts the impact object, the anti-collision plate 211 is pressed toward the second energy absorbing structure 214 through the two support rods 216. The second energy absorbing structure 214 descends relative to the support seat 212, and is thereby pressed toward the first energy absorbing structure 213 through the two transmission rods 215. Then, the second energy absorbing structure 214 cooperates with the first energy absorbing structure 213 to complete the energy absorption process.

[0027] Furthermore, the first energy absorption structure 213 includes a first guide rod 2131, a first elastic member 2132 and two sliders 2133, and the two ends of the first guide rod 2131 are connected to the support seat 212; the first elastic member 2132 and the two sliders 2133 are both mounted on the side surface of the first guide rod 2131, wherein the two sliders 2133 are arranged at the two ends of the first elastic member 2132, so that the two sliders 2133 can compress the first elastic member 2132 from both ends. Specifically, the two sliders 2133 are hinged to the two transmission rods 215 one by one, and the ends of the two transmission rods 215 facing away from the corresponding sliders 2133 are hinged to the two support rods 216 one by one. Therefore, when the anti-collision plate 211 compresses the second energy absorption structure 214 and the first energy absorption structure 213 in sequence through the two support rods 216, the second energy absorption structure 214 descends, prompting the two support rods 216 to drive the two sliders 2133 to move toward each other through the corresponding transmission rods 215, and then compress the first elastic member 2132 between the two sliders 2133, thereby realizing the energy absorption effect of the first energy absorption structure 213.

[0028] Furthermore, the second energy absorption structure 214 includes a second guide rod 2141 and two second elastic members 2142, and the two ends of the second guide rod 2141 are slidingly connected to the support seat 212; the two second elastic members 2142 and the two support rods 216 are all sleeved on the side surface of the second guide rod 2141, wherein one end of each support rod 216 is slidingly connected to the second guide rod 2141, and the other end of each support rod 216 is slidingly connected to the bottom surface of the anti-collision plate 211, and the two second elastic members 2142 are respectively arranged on the opposite sides of the two support rods 216. When the anti-collision plate 211 compresses the first energy absorbing structure 213, the two support rods 216 drive the two sliders 2133 to move toward each other through the corresponding transmission rods 215. During this process, the reaction force of the first elastic member 2132 is transmitted to the two support rods 216 through the two transmission rods 215, prompting the two support rods 216 to move toward opposite sides respectively, and then compress the two second elastic members 2142, so that the second energy absorbing structure 214 cooperates with the first energy absorbing structure 213 to complete the energy absorption effect on the anti-collision plate 211.

[0029] In one embodiment, Furthermore, the car roof safety protection device 200 also includes a fire prevention mechanism 220, which is disposed on the top of the car body 100; the fire prevention mechanism 220 is disposed on the top wall of the car body 100, and when the fire prevention mechanism 220 is open, the fire prevention mechanism 220 can connect the interior and exterior of the car body 100, thereby ensuring ventilation and smoke exhaust efficiency within the car body 100. When the fire prevention mechanism 220 is closed, the fire prevention mechanism 220 can prevent external fire sources from spreading to the interior of the car body 100. In one embodiment, the fire prevention mechanism 220 is configured as a fire damper to achieve ventilation, smoke exhaust, and fire prevention functions on the top wall of the car body 100.

[0030] Furthermore, the control device 300 includes a controller 310 and a position sensor 320. The controller 310 is installed inside the car body 100, and the position sensor 320 is arranged at the bottom of the support seat 212; the position sensor 320 is electrically connected to the controller 310, so that the controller 310 can monitor the compression condition of the anti-collision mechanism 210 in real time through the position sensor 320.

The car top safety protection device is arranged on the top of the car body, and the control device is electrically connected to the car top safety protection device, so that during the operation of the car body, the control device can monitor and control the car top safety protection device in real time to realize the safety protection function of the car top safety protection device on the top of the car body. Specifically, the car top safety protection device includes an anti-collision mechanism, and the anti-collision mechanism and the fire prevention mechanism are both arranged on the top of the car body, wherein the anti-collision mechanism is arranged on the outer surface of the top wall of the car body, so that the anti-collision mechanism can act as an energy absorption unit to absorb the energy of the collision on the top of the car body, thereby realizing collision protection for the top of the car. The car roof safety protection device also includes a fire protection mechanism, which is arranged on the top of the car body; the fire protection mechanism is arranged on the top wall of the car body, and when the fire protection mechanism is opened, the fire protection mechanism can connect the inside and outside of the car body, thereby ensuring the ventilation and smoke exhaust efficiency inside the car body. When the fire protection mechanism is closed, the fire protection mechanism can prevent external fire sources from spreading to the inside of the car body.
