Description

[0001] The present invention relates to the technical field of elevator safety management, and particularly to an elevator safety management device with intelligent control and its method. Background Technique

[0002] At present, with the booming development of modern architecture, elevators, as the core tools for vertical transportation, are widely used in various high-rise buildings, commercial complexes, and residential communities, greatly improving the convenience of people's lives and work. With the accelerating urbanization process, the building scale is constantly expanding, and the usage frequency and quantity of elevators have increased explosively, and their safe operation has become the focus of social attention.

[0003] Currently, mainstream elevators mostly adopt an internal braking system based on the electromagnetic braking principle. When the elevator is running normally, this system uses electromagnetic force to make the brake shoes hold the brake wheel tightly to achieve the deceleration and stop of the elevator. However, in hot summer weather, the temperature in the elevator machine room is too high, and the magnetism of the electromagnetic brake will weaken, resulting in unstable braking force. Therefore, an elevator safety management device with intelligent control and its method are proposed to solve the above-mentioned problems. Summary of the Invention

The electric hydraulic cylinder is connected to the inner wall of the right side of the outer box body. The electric hydraulic cylinder is self-locking. The piston end of the electric hydraulic cylinder penetrates through the fixed frame and is fixedly connected to the right side of the moving block. The piston rod of the electric hydraulic cylinder is slidably connected to the fixed frame. The PLC controller 1 is connected to the inner wall of the right side of the outer box body. The PLC controller 1 is signal-connected to the electric hydraulic cylinder. The PLC controller 1 is signal-connected to the central processor of the elevator. A guide plate is fixedly connected to the inner side of the top of the fixed frame. A guide hole is opened on the front surface of the guide plate. A guide rod is fixedly connected to the back surface of the installation frame.

[0007] Preferably, the left end of the guide hole is inclined downward, and the guide rod is slidably connected to the inner wall of the guide hole.

[0008] Preferably, the number of both the slide bar 1 and the slide bar 2 is two, and they are symmetrically arranged respectively.

[0009] Preferably, a cooling mechanism is provided on the outer box body. The cooling mechanism includes: a temperature sensor, an oil tank, an oil pump, a PLC controller 2, and a support block. The temperature sensor is connected to the friction deceleration plate. The oil tank is fixedly connected to the inner wall of the bottom of the outer box body. Cooling oil liquid is contained in the oil tank. The oil pump is connected to the inner wall of the bottom of the outer box body. The PLC controller 2 is connected to the inner wall of the bottom of the outer box body. The support block is fixedly connected to the inner wall of the bottom of the outer box body. A spray oil pipe is fixedly connected to the top of the support block.

[0010] Preferably, the input end of the oil pump is communicated with the oil tank through a pipeline, and the output end of the oil pump is communicated with the spray oil pipe through a pipeline.

[0011] Preferably, the PLC controller 2 is respectively signal-connected to the temperature sensor and the oil pump. The end of the spray oil pipe far from the oil pump is provided with an atomizing nozzle and is close to the joint of the rotating wheel and the friction deceleration plate.

[0012] Preferably, an oil suction mechanism is provided on the outer box body. The oil suction mechanism includes an oil leakage hole and an oil sump. The oil leakage hole is opened on the support base and is located below the rotating wheel. The oil sump is opened on the inner wall of the bottom of the outer box body, and an oil absorption sponge is connected in the oil sump.

[0013] The present invention provides an intelligent control method for elevator safety management, which is applied to the above-mentioned intelligent control device for elevator safety management. The method includes the following steps:

[0014] S1: When the elevator needs to decelerate, the PLC controller 1 controls the electric hydraulic cylinder to start. The piston end of the electric hydraulic cylinder extends, pushing the moving block to slide leftward along the slide rod 1. The moving block drives the connecting frame and the mounting frame to move synchronously. At the same time, the movement of the mounting frame drives the guide rod to slide in the guide hole, so that the guide rod drives the mounting frame to slide along the slide rod 2 under the limitation of the guide hole, so that the mounting frame moves leftward and downward at the same time. The triangular plate at the bottom of the mounting frame drives the friction deceleration piece to move downward until it contacts the rotating wheel. Friction is generated between the friction deceleration piece and the rotating wheel, hindering the rotation of the rotating wheel and the rotating assembly connected thereto, thereby realizing the deceleration of the elevator;

[0015] S2: When the friction deceleration piece generates heat due to friction with the rotating wheel and the temperature reaches the preset high temperature threshold, the temperature sensor transmits the temperature signal to the PLC controller 2;

[0016] S3: After receiving the signal, the PLC controller 2 controls the oil pump to start. The input end of the oil pump pumps out the cooling oil liquid in the fuel tank through the pipeline. After the oil liquid is pressurized by the oil pump, it is transported to the spray oil pipe through the pipeline at the output end. The atomizing nozzle atomizes and sprays the oil liquid. The oil liquid forms an oil film on the surfaces of the rotating wheel and the friction deceleration piece, playing a role in cooling and lubrication, reducing the temperature of the friction deceleration piece and the rotating wheel, and reducing the wear between them;

[0017] S4: When the temperature of the friction deceleration piece drops to the normal range, the temperature sensor sends a signal to the PLC controller 2, and the PLC controller 2 controls the oil pump to stop working;

[0018] S5: During the cooling process, the excess oil liquid and the oil stains generated by the operation of the equipment will drip downward through the oil leakage holes opened on the support base. The oil stains flow into the oil sump for centralized collection. The oil absorption sponge in the oil sump has good oil absorption performance and can absorb the oil stains in the oil sump. This can prevent the accumulation of oil stains in the equipment, avoid corrosion of the equipment caused by oil stains, and keep the inside of the equipment clean.

[0019] The present invention adopts the above technical solutions and can bring the following beneficial effects:

[0020] 1. For this intelligent control elevator safety management device and its method, the electric hydraulic cylinder starts under the control of PLC controller 1, pushing the moving block to slide along slide bar 1. The moving block drives the connecting frame and the mounting frame to move. At the same time, the movement of the mounting frame drives the guide rod to slide in the guide hole, so that the guide rod drives the mounting frame to slide along slide bar 2 under the limitation of the guide hole, making the mounting frame move leftward and downward at the same time. Then the mounting frame drives the triangular plate and the friction deceleration piece to move, making the friction deceleration piece contact the rotating wheel and generate frictional force, realizing the deceleration braking of the elevator. This external friction deceleration method cooperates with the traditional electromagnetic internal braking system. Even when the magnetism of the electromagnetic brake weakens in a high-temperature environment, the external friction deceleration mechanism can still work stably, ensuring reliable braking of the elevator under various working conditions and effectively reducing the occurrence probability of elevator safety accidents.

[0021] 2. For this intelligent control elevator safety management device and its method, the temperature sensor monitors the temperature of the friction deceleration piece in real time. When the temperature is too high, PLC controller 2 controls the oil pump to extract cooling oil from the fuel tank and spray it through the atomizing nozzle of the spray oil pipe to the joint of the rotating wheel and the friction deceleration piece. The oil plays a role in cooling and lubrication, reducing the wear of the friction deceleration piece and the rotating wheel, reducing component damage caused by high temperature, extending the overall service life of the equipment, and reducing the maintenance cost.

[0022] 3. For this intelligent control elevator safety management device and its method, the cooling oil and the oil stains generated during the operation of the equipment fall through the oil leakage hole and flow into the oil collecting tank. The oil absorbing sponge in the oil collecting tank absorbs the oil stains, preventing the oil stains from accumulating in the equipment, avoiding corrosion of the equipment caused by the oil stains, reducing the pollution of the elevator operation environment by the oil stains, keeping the equipment clean, and being beneficial to the long-term stable operation of the equipment.

A second slide bar 55 is fixedly connected to the inner cavity of the connecting frame 54. The number of the first slide bar 52 and the second slide bar 55 is two, and they are symmetrically arranged respectively. An installation frame 56 is slidably connected to the outer wall of the second slide bar 55. The installation frame 56 is arranged in an inverted "C" shape. A triangular plate 57 is fixedly connected to the bottom of the installation frame 56. A friction deceleration plate 58 is fixedly connected to the bottom of the triangular plate 57 and is located above the rotating wheel 4. The electric hydraulic cylinder 59 is connected to the right inner wall of the housing 2. The electric hydraulic cylinder 59 is self-locking. The piston end of the electric hydraulic cylinder 59 penetrates through the fixed frame 51 and is fixedly connected to the right side of the moving block 53. The piston rod of the electric hydraulic cylinder 59 is slidably connected to the fixed frame 51. The PLC controller I 510 is connected to the right inner wall of the housing 2. The PLC controller I 510 is in signal connection with the electric hydraulic cylinder 59. The PLC controller I 510 is in signal connection with the central processor of the elevator.

The left end of the guide hole 512 is inclined downward. A guide rod 513 is fixedly connected to the back of the installation frame 56. The guide rod 513 is slidably connected to the inner wall of the guide hole 512. The electric hydraulic cylinder 59 is started under the control of the PLC controller I 510 to push the moving block 53 to slide along the first slide bar 52. The moving block 53 drives the connecting frame 54 and the installation frame 56 to move. At the same time, the movement of the installation frame 56 drives the guide rod 513 to slide in the guide hole 512, so that the guide rod 513 drives the installation frame 56 to slide along the second slide bar 55 under the limitation of the guide hole 512, so that the installation frame 56 moves leftward and downward at the same time, and then the installation frame 56 drives the triangular plate 57 and the friction deceleration plate 58 to move, so that the friction deceleration plate 58 contacts the rotating wheel 4 and generates friction force, realizing the deceleration braking of the elevator. This external friction deceleration method cooperates with the traditional electromagnetic internal braking system. Even when the magnetism of the electromagnetic brake weakens in a high-temperature environment, the external friction deceleration mechanism 5 can still work stably, ensuring reliable braking of the elevator under various working conditions and effectively reducing the occurrence probability of elevator safety accidents.

[0036] Working principle: When the elevator needs to decelerate, the central processor of the elevator sends a deceleration signal to the first PLC controller 510. The first PLC controller 510 receives the signal and controls the start of the electro-hydraulic cylinder 59. The piston end of the electro-hydraulic cylinder 59 extends, pushing the moving block 53 to slide leftward along the first slide rod 52. The moving block 53 drives the connecting frame 54 and the mounting frame 56 to move synchronously. At the same time, the movement of the mounting frame 56 drives the guide rod 513 to slide in the guide hole 512, so that the guide rod 513 drives the mounting frame 56 to slide along the second slide rod 55 under the limitation of the guide hole 512, causing the mounting frame 56 to move leftward and downward at the same time. The triangular plate 57 at the bottom of the mounting frame 56 drives the friction deceleration piece 58 to move downward until it contacts the rotating wheel 4. Friction is generated between the friction deceleration piece 58 and the rotating wheel 4, hindering the rotation of the rotating wheel 4 and the rotating assembly connected thereto, thereby achieving the deceleration of the elevator.

The second PLC controller 64 is respectively in signal connection with the temperature sensor 61 and the oil pump 63. The support block 65 is fixedly connected to the bottom inner wall of the outer box body 2. A spray oil pipe 66 is fixedly connected to the top of the support block 65. The input end of the oil pump 63 is communicated with the oil tank 62 through a pipeline, and the output end of the oil pump 63 is communicated with the spray oil pipe 66 through a pipeline. The end of the spray oil pipe 66 away from the oil pump 63 is provided with an atomizing nozzle and is close to the joint of the rotating wheel 4 and the friction deceleration piece 58. The temperature of the friction deceleration piece 58 is monitored in real time through the temperature sensor 61. When the temperature is too high, the second PLC controller 64 controls the oil pump 63 to extract the cooling oil from the oil tank 62 and spray it onto the joint of the rotating wheel 4 and the friction deceleration piece 58 through the atomizing nozzle of the spray oil pipe 66. The oil plays a role in cooling and lubrication, reducing the wear of the friction deceleration piece 58 and the rotating wheel 4, reducing the damage of components caused by high temperature, extending the overall service life of the equipment, and reducing the maintenance cost.

[0038] Working principle: When the friction deceleration piece 58 generates heat due to friction with the rotating wheel 4 and the temperature reaches the preset high temperature threshold, the temperature sensor 61 transmits the temperature signal to the second PLC controller 64. After receiving the signal, the second PLC controller 64 controls the oil pump 63 to start. The input end of the oil pump 63 pumps out the cooling oil fluid in the fuel tank 62 through a pipeline. After the oil fluid is pressurized by the oil pump 63, it is transported to the fuel injection pipe 66 through the pipeline at the output end. The atomizing nozzle atomizes and sprays out the oil fluid, and the oil fluid forms an oil film on the surfaces of the rotating wheel 4 and the friction deceleration piece 58, playing a role in cooling and lubrication, reducing the temperature of the friction deceleration piece 58 and the rotating wheel 4, and reducing the wear between them. When the temperature of the friction deceleration piece 58 drops to the normal range, the temperature sensor 61 sends a signal to the second PLC controller 64, and the second PLC controller 64 controls the oil pump 63 to stop working.

The cooling oil fluid and the oil stains generated during the operation of the equipment fall through the oil leakage hole 71 and flow into the oil collecting groove 72. The oil absorbing sponge 73 in the oil collecting groove 72 absorbs the oil stains, preventing the oil stains from accumulating in the equipment, avoiding the corrosion of the equipment caused by the oil stains, and at the same time reducing the pollution of the elevator operation environment by the oil stains, keeping the equipment clean, and being beneficial to the long-term stable operation of the equipment.

[0040] Working principle: During the cooling process, the excess oil fluid and the oil stains generated during the operation of the equipment will drip downward through the oil leakage hole 71 opened on the support base 3, and the oil stains flow into the oil collecting groove 72 for centralized collection.

7. An elevator safety management device with intelligent control according to claim 1, characterized in that: An oil suction mechanism (7) is arranged on the outer box body (2). The oil suction mechanism (7) includes: an oil leakage hole (71) and an oil collecting groove (72). The oil leakage hole (71) is opened on the support seat (3) and is located below the rotating wheel (4). The oil collecting groove (72) is opened on the inner wall of the bottom of the outer box body (2), and an oil suction sponge (73) is connected in the oil collecting groove (72).

8. An elevator safety management method with intelligent control, applied to an elevator safety management device with intelligent control as described in any one of claims 1-7, characterized in that: The method includes the following steps: S1: When the elevator needs to decelerate, the first PLC controller (510) controls the electric hydraulic cylinder (59) to start. The piston end of the electric hydraulic cylinder (59) extends, pushing the moving block (53) to slide leftward along the first slide bar (52). The moving block (53) drives the connecting frame (54) and the mounting frame (56) to move synchronously. At the same time, the movement of the mounting frame (56) drives the guide rod (513) to slide in the guide hole (512), so that the guide rod (513) drives the mounting frame (56) to slide along the second slide bar (55) under the limitation of the guide hole (512), so that the mounting frame (56) moves leftward and downward at the same time. The triangular plate (57) at the bottom of the mounting frame (56) drives the friction decelerating piece (58) to move downward until it contacts the rotating wheel (4). Friction is generated between the friction decelerating piece (58) and the rotating wheel (4), hindering the rotation of the rotating wheel (4) and the rotating assembly connected thereto, thereby realizing the deceleration of the elevator; S2: When the friction decelerating piece (58) generates heat due to friction with the rotating wheel (4) and the temperature reaches the preset high temperature threshold, the temperature sensor (61) transmits the temperature signal to the second PLC controller (64); S3: After receiving the signal, the second PLC controller (64) controls the oil pump (63) to start. The input end of the oil pump (63) pumps out the cooling oil in the fuel tank (62) through a pipeline. After the oil is pressurized by the oil pump (63), it is transported to the fuel injection pipe (66) through the pipeline at the output end. The atomizing nozzle atomizes and sprays the oil. The oil forms an oil film on the surfaces of the rotating wheel (4) and the friction decelerating piece (58), playing a role in cooling and lubrication, reducing the temperature of the friction decelerating piece (58) and the rotating wheel (4), and reducing the wear between them; S4: When the temperature of the friction decelerating piece (58) drops to the normal range, the temperature sensor (61) sends a signal to the second PLC controller (64), and the second PLC controller (64) controls the oil pump (63) to stop working; S5: During the cooling process, the excess oil and the oil stains generated by the operation of the equipment will drip downward through the oil leakage holes (71) opened on the support base (3), and the oil stains will flow into the oil collecting tank (72) for centralized collection. The oil absorbing sponge (73) in the oil collecting tank (72) has good oil absorption performance and can absorb the oil stains in the oil collecting tank (72). This can prevent the oil stains from accumulating in the equipment, avoid corrosion of the equipment caused by the oil stains, and keep the interior of the equipment clean.
