Description

Technical Field

[0001] The utility model belongs to the technical field of rescue tools, and in particular relates to an elevator auxiliary emergency rescue tool. Background Art

[0002] At present, all subway elevators are machine room-less elevators, and the rescue devices configured are either electric brake release or mechanical brake release. Electric brake release: The main structure consists of a brake (holding brake), a brake control panel and an emergency battery. Its working principle is that the emergency battery provides power to the brake control panel, controls the release of the brake coil magnetic force, causes the brake arm to open and close, and moves the elevator car to the leveling position through the weight difference between the car and the counterweight. Mechanical brake release: The main structure consists of a brake (holding brake), a brake release wire rope and a brake release wrench. Its working principle is that the brake release wrench is linked to the brake release wire rope, and the wire rope pulls the brake arm of the brake to open and close, and moves the elevator car to the leveling position through the weight difference between the car and the counterweight.

[0003] The elevator's built-in emergency rescue device (electric brake release) is mainly composed of a brake release plate and an emergency battery. Therefore, the reliability and stability of the brake release plate and the emergency battery determine whether the rescue mission can be successful.

[0004] The brake release board is composed of integrated electronic circuits and is accompanied by multiple auxiliary sub-modules. In actual use, it is inevitable that the brake release board and its auxiliary modules will fail. The rescue process is highly dependent on the brake release board. If the brake release board malfunctions, it is not only difficult to diagnose the fault, but also difficult to replace due to the small operating space and many external lines. Therefore, repairing the brake release board fault or replacing the faulty brake release board will inevitably greatly increase the rescue time of the elevator trapped people.

[0005] The emergency battery is the only power source in the electric brake release emergency rescue device. Most elevator manufacturers do not have battery capacity monitoring, and cannot detect the low power of the emergency battery in advance, making it difficult to support the entire rescue process. Therefore, during the rescue process, if the emergency battery capacity is found to be insufficient, it is necessary to replace the spare parts. Because the emergency battery is a flammable and explosive item, it cannot be stored nearby, resulting in a long time to retrieve, which reduces the rescue efficiency and increases the difficulty of rescue.

[0018] Figure 2 The utility model is a circuit schematic diagram of an elevator auxiliary emergency rescue tool. DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, but not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] It should be understood that it should also be noted that in the embodiment, the functions / actions that appear may be different from the order in which the drawings appear. For example, depending on the functions / actions involved, they can actually be executed substantially concurrently, or two figures shown in succession can sometimes be executed in the reverse order.

[0021] like Figure 1 and Figure 2 As shown, an elevator auxiliary emergency rescue tool of this embodiment mainly includes a control box 1 and a control module. The control module is installed in the control box 1. The control module is connected to a power plug 5 through a group of wires, and the power plug 5 is used to connect an external power supply; the control module is also connected to a plug-in 6 through a group of wires, and the plug-in 6 is used to be plugged into the brake 10 of the faulty elevator.

[0022] The control module includes an adjustable transformer 2, the input end of the adjustable transformer 2 is connected to the power plug 5 through the emergency stop switch button 3, and the working function of the entire tool can be cut off through the emergency stop switch button, which can effectively ensure that the tool button or line is out of control when abnormal; the output end of the adjustable transformer 2 is connected to the plug-in 6 through the self-reset button 4. The adjustable transformer 2 is connected to the adjustable potentiometer 8, and the output voltage of the adjustable transformer 2 can be adjusted according to the difference in brake voltage of elevator brands through the adjustable potentiometer 8. The emergency stop switch button 3, the self-reset button 4 and the adjustable potentiometer 8 are all installed on the control box 1.

[0023] The control module is also connected to the display screen 7 and the indicator light. The display screen 7 is used to display the voltage at the output end of the adjustable transformer 2 and verify that the control module is working properly. The indicator light is used to display the switch working condition of the self-reset button 4. In this embodiment, the self-reset button 4 adopts a self-reset light button, that is, the indicator light is integrated on the self-reset button. When the self-reset light button is pressed, the light turns on, and when the switch is released, the light turns off.

[0024] The control module is also connected to the heat dissipation fan. The control box 1 is provided with heat dissipation holes 9. The heat dissipation fan is arranged on the control box 1 and is arranged opposite to the heat dissipation holes 9. The operation of the heat dissipation fan verifies that the control module is working normally.

[0025] In this embodiment, the control box is roughly in the shape of a rectangular parallelepiped and is made of ABS. It has the functions of pressure resistance and waterproofness, is small in size, can be fixed or moved, and is easy to carry. The power of the adjustable transformer 2 is 360W; the model of the emergency stop switch button 3 is LA38-11ZS; the model of the self-reset button 4 is LA18-22; the power plug 5 is a national standard 10A universal plug; the plug-in 6 is a plug with a pin gap of 5.08MM to prevent mis-insertion.

[0026] When the elevator electric brake release rescue device fails, first connect the 4-pin plug with the anti-misinsertion function of the brake 10 of the faulty elevator to the plug-in 6 of the elevator auxiliary emergency rescue tool, confirm that the emergency stop switch button 3 is in working condition, and then insert the power plug 5 into the three-phase 220V power socket near the elevator control cabinet or the equipment to provide external driving power to the elevator auxiliary emergency rescue tool. Rotate and release the emergency stop switch button 3. At this time, the cooling fan also starts running. When the operator sees that the cooling fan starts running, the display screen 7 synchronously displays the initial output voltage. Rotate the voltage adjustment lever of the adjustable transformer 2 according to the manufacturer's brand elevator instructions, and adjust the output voltage to the brake control voltage of the brand elevator. The installation and debugging are completed.

[0027] During the rescue, the operator presses the self-reset button 4 and observes that the indicator light comes on (proving that voltage has been output to the coil of the elevator brake). The elevator working brake is opened, and the car is moved under the action of the gravity difference between the car and the counterweight. The self-reset button 4 is pressed and released for 2 seconds, and the indicator light goes out (proving that the output voltage of the elevator brake coil has stopped). The operator confirms the position of the car by visual inspection through the elevator hall door glass or the leveling indicator light on the elevator control mainboard. After continuously pressing the self-reset button 4 to move the car to the position where the car door and the hall door are level, the emergency stop switch button 3 is pressed (to cut off the power supply of the tool), and the cooling exhaust fan stops. At the same time, the display screen 7 goes black, proving that the tool has failed to function. Then the power plug 5 is unplugged to cut off the external power supply, and the hall car door is opened in the leveling area to rescue the trapped people.

[0028] This tool makes up for the lack of disposal measures after the equipment rescue device fails. Under the same environment, skilled personnel use traditional methods to conduct time-consuming tests (replacement of faulty parts): one person takes 19 minutes to disassemble and assemble the brake plate, and one person takes 15 minutes to disassemble and assemble the battery. In addition, the rescue takes 2 minutes, and the total time is close to 20 minutes. However, the rescue work can be completed in just 3 minutes using this tool, which greatly shortens the rescue time.

[0029] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
