Description

Technical Field

[0001] The present invention relates to the technical field related to elevator rescue devices, and in particular to a machine room-less elevator rescue device. Background Art

[0002] The rescue device of the machine roomless elevator shall comply with the provisions of 5.9.2.2.2.9 in GB / T 7588.1-2020:

[0003] 5.9.2.2.2.9 For manual release brakes, when the car is loaded with the following loads:

[0004] — less than or equal to (q-0.1)Q; or

[0005] —greater than or equal to (q+0.1)Q and less than or equal to Q.

[0006] in:

[0007] q—Balance factor, which indicates the amount by which the rated load is balanced by the counterweight;

[0008] Q—rated load capacity;

[0009] The car should be able to be moved to a nearby landing in the following ways:

[0010] a) spontaneous movement due to gravity; or

[0011] b) Manual operation, including:

[0012] 1) Mechanical devices placed on site; or

[0013] 2) An electric device placed on site that is independent of the main power supply.

[0014] According to 5.9.2.2.2.9, when the car load (W) is W≤(q-0.1)Q or (q+0.1)Q≤W≤Q, after manually releasing the brake of the driving main machine, the car is moved to the nearby landing. At least one of the methods given in 5.9.2.2.2.9a) or b) should be adopted, and the methods given in 5.9.2.2.2.9a) or b) can be used together on the same elevator.

[0015] Item 5.9.2.2.2.9a) means that after the brake is manually released, the main engine traction sheave is driven to rotate under the action of the torque generated by the gravity difference on its two sides (the car body side and the counterweight side), so that the car and counterweight move by themselves.

[0016] Item 5.9.2.2.2.9b) means: manually releasing the brake and using a manually operated mechanical device or electric device (if the device can be removed or disconnected from the main drive, the mechanical device or electric device placed on site must first be connected to the main drive) to move the car.

[0017] For manually operated electric devices, the most unfavorable working conditions (such as maximum load, maximum floor spacing, etc.) should be considered. Therefore, the capacity of the independent power supply used should be large enough to ensure that the car with rated load can be moved to the nearby floor station at a speed of no more than 0.3m / s during the rescue period (1h) after the elevator fails. The capacity of the commonly used independent power supply on the market cannot meet the requirements, and the cost is high, so the manually operated electric device is not considered.

[0018] For manually operated mechanical devices, the handwheel that is widely used on machine room elevators belongs to this type of device. Because the driving host of the machine roomless elevator is installed at the top of the shaft, the rescue personnel cannot reach the vicinity of the host when the elevator fails. Therefore, the handwheel used for the machine room elevator is not suitable for the machine roomless elevator. It is necessary to design a manually operated mechanical device based on the situation of the machine roomless elevator itself.

[0019] When the car is carrying any load within the range specified in 5.9.2.2.2.9 and the brake is released manually, if the car can always move by itself relying solely on the gravity difference on both sides of the driving main unit, the elevator does not need to be equipped with a mechanical device; however, in engineering practice, due to uncontrollable factors such as traction capacity and mechanical efficiency, the car cannot always move by itself relying solely on gravity difference. In this case, a mechanical device should be installed to move the car manually within the load range that the car cannot move by itself.

[0020] The commonly used rescue devices for machine room-less elevators are mostly compensation devices - compensation chains (rope) and emergency electric operation control devices. The former is that the relative position of the car and the counterweight changes continuously during the operation of the elevator, which will cause the weight difference of the wire rope on both sides of the traction wheel to change. The higher the elevator lifting height, the greater the difference in the deadweight of the wire rope on both sides of the traction wheel, and the greater the impact on the traction force and the power of the drive motor. In order to ensure sufficient traction or drive motor power, it is necessary to consider setting up a compensation device to compensate for the deadweight of the traction wire rope according to the elevator lifting height. Usually, the compensation chain is used as the compensation device for the rated speed of the elevator V≤3.0m / s, and the compensation rope is used as the compensation device for V>3.0m / s. Whether a compensation device needs to be set is determined by calculation and testing, and not every elevator needs to be set up with a compensation device. If every elevator is equipped with a compensation device just for the low-probability working condition that the elevator cannot rely on the gravity difference to move the car, the cost of the elevator will increase significantly, and there are disadvantages: if a compensation chain is used as the compensation device, the total length of the counterweight frame will be reduced, and the cost of the counterweight block will face an increase; if a compensation rope is used as the compensation device, the tensioning device therein has unique setting requirements, and the pit depth dimension requirement is relatively high, which cannot be met for conventional machine roomless elevators; and the latter is not equipped with an emergency electric operation control device because the cost of the emergency electric operation control device is higher than the cost of setting up the compensation device. At the same time, if the emergency electric operation control device is to be used as a rescue device, the emergency electric operation control device should also have a main power supply that has not been lost or a backup power supply, and the capacity of the backup power supply should be large enough, which requires a lot of cost in the engineering practice. In order to solve the above problems, a machine roomless elevator rescue device is proposed. Summary of the invention

[0047] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0048] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0049] Reference Figures 1 to 6As shown, the rescue device of the machine roomless elevator shall comply with the provisions of 5.9.2.2.2.9 in GB / T 7588.1-2020:

[0050] 5.9.2.2.2.9 For manual release brakes, when the car is loaded with the following loads:

[0051] — less than or equal to (q-0.1)Q; or

[0052] —greater than or equal to (q+0.1)Q and less than or equal to Q.

[0053] in:

[0054] q—Balance factor, which indicates the amount by which the rated load is balanced by the counterweight;

[0055] Q—rated load capacity;

[0056] The car should be able to be moved to a nearby landing in the following ways:

[0057] a) spontaneous movement due to gravity; or

[0058] b) Manual operation, including:

[0059] 1) Mechanical devices placed on site; or

[0060] 2) An electric device placed on site that is independent of the main power supply.

[0061] According to 5.9.2.2.2.9, when the car load (W) is W≤(q-0.1)Q or (q+0.1)Q≤W≤Q, after manually releasing the brake of the driving main machine, the car is moved to the nearby landing. At least one of the methods given in 5.9.2.2.2.9a) or b) should be adopted, and the methods given in 5.9.2.2.2.9a) or b) can be used together on the same elevator.

[0062] Item 5.9.2.2.2.9a) means that after the brake is manually released, the main engine traction sheave is driven to rotate under the action of the torque generated by the gravity difference on its two sides (the car body side and the counterweight side), so that the car and counterweight move by themselves.

[0063] Item 5.9.2.2.2.9b) means: manually releasing the brake and using a manually operated mechanical device or electric device (if the device can be removed or disconnected from the main drive, the mechanical device or electric device placed on site must first be connected to the main drive) to move the car.

[0064] For manually operated electric devices, the most unfavorable working conditions (such as maximum load, maximum floor spacing, etc.) should be considered. Therefore, the capacity of the independent power supply used should be large enough to ensure that the car with rated load can be moved to the nearby floor station at a speed not exceeding 0.3m / s during the rescue period (1h) after the elevator fails. The capacity of the commonly used independent power supplies on the market cannot meet the requirements, and the cost is high, so manually operated electric devices are not considered.

[0065] For manually operated mechanical devices, the handwheel that is widely used on machine room elevators belongs to this type of device. Because the driving host of the machine roomless elevator is installed at the top of the shaft, the rescue personnel cannot reach the vicinity of the host when the elevator fails. Therefore, the handwheel used for the machine room elevator is not suitable for the machine roomless elevator. It is necessary to design a manually operated mechanical device based on the situation of the machine roomless elevator itself.

[0066] When the car is carrying any load within the range specified in 5.9.2.2.2.9 and the brake is released manually, if the car can always move by itself relying solely on the gravity difference on both sides of the driving main unit, the elevator does not need to be equipped with a mechanical device; however, in engineering practice, due to uncontrollable factors such as traction capacity and mechanical efficiency, the car cannot always move by itself relying solely on gravity difference. In this case, a mechanical device should be installed to move the car manually within the load range that the car cannot move by itself.

[0067] The commonly used rescue devices for machine room-less elevators are mostly compensation devices - compensation chains (rope) and emergency electric operation control devices. The former is that the relative position of the car and the counterweight changes continuously during the operation of the elevator, which will cause the weight difference of the wire rope on both sides of the traction wheel to change. The higher the elevator lifting height, the greater the difference in the deadweight of the wire rope on both sides of the traction wheel, and the greater the impact on the traction force and the power of the drive motor. In order to ensure sufficient traction or drive motor power, it is necessary to consider setting up a compensation device to compensate for the deadweight of the traction wire rope according to the elevator lifting height. Usually, the compensation chain is used as the compensation device for the rated speed of the elevator V≤3.0m / s, and the compensation rope is used as the compensation device for V>3.0m / s. Whether a compensation device needs to be set is determined by calculation and testing, and not every elevator needs to be set up with a compensation device. If every elevator is equipped with a compensation device just for the low-probability condition that the elevator cannot rely on gravity difference to move the car, the cost of the elevator will increase significantly, and there are disadvantages: if a compensation chain is used as a compensation device, the total length of the counterweight frame will be reduced, and the cost of the counterweight block will face an increase; if a compensation rope is used as a compensation device, the tensioning device therein has unique setting requirements, and the pit depth requirement is relatively high, which cannot be met for conventional machine room-less elevators; and the latter is not suitable for every elevator because the cost of the emergency electric operation control device is higher than the cost of setting up the compensation device. An emergency electric operation control device is configured. If the emergency electric operation control device is to be used as a rescue device, the emergency electric operation control device should also have a main power supply that is not lost or a backup power supply, and the capacity of the backup power supply should be large enough. In the process of engineering practice, a great cost is required. In order to solve the above problems, a machine room-less elevator rescue device is proposed; it includes a car body and a counterweight part arranged in the elevator shaft, and a rescue structure is arranged between the car body and the counterweight part, and the rescue structure includes a rescue wire rope, a plurality of guide devices, a tensioning device, a hand chain hoist and a wire rope hoist;

[0068] A plurality of mounting parts for mounting and fixing at the bottom of the hoistway are provided at the lower sides of the guide devices 2 and the tensioning devices 3. One end of the rescue wire rope 14 is provided at the bottom of the car and is connected to one side of the counterweight along the guide devices 2 and the tensioning devices 3 to form a complete closed loop.

[0069] The wire rope hoist 42 is detachably connected to the rescue wire rope 14 on the car body side or the counterweight side, the top clamp ring of the hand chain hoist 41 is clamped into the wire rope hoist 42, and the bottom clamp ring is clamped into the mounting member for manual vertical movement of the car for rescue;

[0070] The upper sides of the car body 153 and the counterweight part 151 are provided with a driving member 15 for driving the car body 153 to vertically rise and fall; by arranging the rescue wire rope 14 under the car and the counterweight, the purpose of solving the spatial size of the guide device 2 of the rescue wire rope 14 is achieved without affecting the total length of the counterweight or the depth of the pit; and the setting of the bottom tensioning device 3 and the guide device 2 can solve the tensioning problem of the rescue wire rope 14. The above structure can also achieve the purposes of easy installation, easy rescue, small space size and low cost, and the rescue structure 4 will not be affected by factors such as traction ratio and mechanical efficiency, thereby ensuring that the rescue process is carried out in an orderly manner.

[0071] It should be noted that the rescue process of the above-mentioned rescue device is that after the brake is manually released by an electrical device (commonly known as electric release, the same below) powered by an automatically charged emergency power supply in the top-level control cabinet, force is applied to the rescue wire rope 14 to move the car forward until the car body 153 can move by itself relying on the gravity difference.

[0072] Furthermore, the above operation process is as follows:

[0073] When the elevator is operating normally, the rescue wire rope 14 moves with the car and the counterweight, and a number of elevator-related mechanical devices are provided in the pit to prevent the rescue wire rope 14 from shaking and getting hooked during operation. Guide devices 2 are provided under the counterweight and the car. Since the traction wire rope 154 will stretch during the normal operation of the elevator, causing the rescue wire rope 14 to relax, a tensioning device 3 should also be provided for the rescue wire rope 14.

[0074] In addition, when the elevator is in the rescue state: if it is a small-load machine room-less elevator (the car can be moved by applying manpower), only one rescue device is needed; after rescuer B enters the pit, rescuer A manually releases the brake through the electric release in the top-level control cabinet, and then rescuer B moves the car body 153 by manually pulling the rescue wire rope 14 within the load range that the car cannot move by itself. When the car body 153 can move by itself relying on the gravity difference, rescuer A suspends releasing the brake, and after rescuer B leaves the pit, releases the brake again to move the car body 153 to the nearby floor station by the gravity difference, and the rescuers open the hall door and the car door to rescue the trapped people.

[0075] It should be noted that if it is a heavy-load machine room-less elevator (the car cannot be moved by human power), ≥ 2 rescue devices should be configured according to the actual situation.

[0076] It should also be noted that in another case: due to factors such as large system friction, high traction ratio, and low mechanical efficiency, the human force pulling the rescue wire rope 14 is insufficient. After rescuer B enters the pit, rescuer A manually releases the brake through the electric brake release in the top control cabinet. Rescuer B refers to Figure 2 As shown, the wire rope hoist 42 is installed on the rescue wire rope 14 on the side that can move the car forward, and the hand winch 41 is connected to the first lifting ring 13 or the second lifting ring 21 set on the pit floor. The hand winch 41 applies force to cause the car to move. When the car body 153 can move by itself due to gravity difference, the rescuer A suspends releasing the brake. After the rescuer B disassembles the wire rope hoist 42 and the hand winch 41 and leaves the pit, the brake is released again to move the car body 153 to the nearby floor station by gravity difference. The rescuers open the hall door and the car door to rescue the trapped people.

[0077] It should be noted that: since the hand chain hoist 41 and the wire rope hoist 42 are common tools for rescuers, they do not need to be equipped in every elevator, which makes the cost of the entire rescue device low.

[0078] Furthermore, referring to Figure 4 and Figure 5 As shown, the specific structure of the above-mentioned guide device 2 is: the guide device 2 includes a guide base composed of a plurality of guide plates 25, and a guide wheel 24 for guiding the rescue wire rope 14 is arranged in the guide base, and the guide base is installed on the pit floor 1 by bolts. The purpose of such arrangement is mainly to save space size, reduce the impact on the total length of the counterweight, and reduce the cost of the counterweight block. The guide wheel 24 is fixed on the side to reduce the ground clearance of the guide wheel 24 on the pit floor 1. At the same time, since the rescue wire rope 14 is subjected to little force during the normal operation of the elevator, the diameter of the guide wheel 24 is controlled to be about 10 times the diameter of the wire rope, thereby reducing the space size occupied by the guide wheel 24.

[0079] In addition, the specific structure of the above-mentioned tensioning device 3 is as follows: the tensioning device 3 includes a tensioning base composed of a plurality of tensioning brackets 31, and the tensioning base is provided with a tensioning wheel 32 for tensioning the rescue wire rope 14, and the tensioning base is installed on the pit floor 1 by bolts. In addition to the above-mentioned structure, the tensioning device 3 is also provided with an adjustable nut at the tail of the tensioning wheel 32, and the tensioning wheel 32 is cleverly arranged at an angle through the structural frame. During installation, the spring is compressed to a suitable position (to ensure that the spring is in an effective state). After the rescue wire rope 14 is installed, the distance between the adjustable nut at the tail of the tensioning wheel 32 and the compression force surface of the spring is adjusted to a suitable position. After the rescue wire rope 14 is relaxed, the spring gradually recovers to achieve the tensioning effect.

[0080] It is worth mentioning that a protective top plate 23 is provided on the mounting brackets of the two guide wheels 24, so that the installation of the protective top plate 23 becomes simple and also achieves the purpose of protecting the above-mentioned guide device 2 and tensioning device 3.

[0081] In addition, the rescue wire rope 14 is connected to the car and counterweight through a conventional compensation chain suspension device, and shares the installation holes of the car body 153 and the bottom of the counterweight, making the structure simple and universal. The rescue wire rope 14 is connected to the car body 153 and the bottom of the counterweight through the car suspension device 11 and the counterweight suspension device 22, and the rescue wire rope is connected to the suspension device through a thimble, and the thimble here can be a heart-shaped thimble, etc.

[0082] Furthermore, the guide device 2 and the tensioning device 3 have small dimensions, which reduces the space occupied, and make the guide device 2 and the tensioning device 3 simple in structure and reduce the number of parts, thereby reducing material costs and processing costs; common tools necessary for rescue personnel: a wire rope hoist 42 and a hand winch 41 are used, and they do not need to be configured for each elevator, thereby reducing the cost of the rescue device.

[0083] In addition, the pit floor 1 , the guide device 2 and the tensioning device 3 are detachably connected, and the first lifting ring 13 and the second lifting ring 21 on the pit floor 1 are both matched with the hand winch 41 .

[0084] It should be noted that the forward movement mentioned above is explained as follows: the operating force applied by the manual mechanical device needs to overcome the combined effect of the friction of the system and the gravity difference on both sides of the traction wheel of the driving main machine. When the direction of the operating force applied by the manual mechanical device is consistent with the positive direction of the gravity difference, the required operating force is smaller, and the movement of the car body 153 caused at this time can be called forward movement.

[0085] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
