Description

[Technical Field]

[0001] This invention relates to the field of elevator technology, and in particular to an elevator with a split-type elevator car. [Background Technology]

[0002] The elevator car is a box-shaped space used to carry and transport people and goods. The car generally consists of main components such as the car floor, car walls, car top, and car doors. It is the elevator body component used to transport passengers, goods, and other loads. Existing elevator cars are mainly constructed by splicing multiple car panels into a single unit. In the event of an elevator malfunction, a few elevators allow passengers to climb out through the passageway at the top of the car for self-rescue. However, most elevators lock the car directly, requiring the doors to be pried open for escape. Prying open the car doors is difficult to do manually from inside the car, and there is a lack of specialized tools for this operation. Furthermore, the process of prying can easily cause the elevator to shake, leading to more serious elevator accidents. [Summary of the Invention]

[0003] In order to solve the problem that elevator cars in the prior art lack self-rescue and escape devices, the purpose of this invention is to provide an elevator with a split elevator car.

[0004] This application is achieved through the following technical solution: an elevator with a split-type elevator car, comprising:

[0005] The car assembly includes a first car and a second car that is separately installed from the first car;

[0006] The drive system, which is installed in the elevator shaft, includes a first drive unit connected to the first car and a second drive unit connected to the second car;

[0007] An electronic control device is electrically connected to the first drive device and the second drive device respectively. The electronic control device controls the first drive device to stop operating and controls the second drive device to operate.

Detailed Implementation Methods

[0025] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] like Figure 1-5 As shown in the figure, this application proposes an elevator with a split-type elevator car, including: a car assembly 1, which includes a first car 11 and a second car 12 separately installed from the first car 11; a drive system 2, which is installed in the elevator shaft, including a first drive device 21 connected to the first car 11 and a second drive device 22 connected to the second car 12; and an electrical control device 3, which is electrically connected to the first drive device 21 and the second drive device 22 respectively. The electrical control device 3 controls the first drive device 21 to stop operating, and controls the second drive device 22 to operate. The second drive device 22 drives the second car 12 to move towards the side away from the first car 11 to the nearest landing door device. Existing elevator cars mainly use multiple car panels spliced ​​into a whole elevator car. When the elevator malfunctions, a few elevators can climb out through the passage at the top of the elevator car for self-rescue, while most elevators directly lock the elevator car, only allowing the car to be locked. Prying open the elevator car door for escape is difficult due to the lack of manpower and specialized tools inside the car, and it can also cause the elevator to shake, potentially leading to a more serious accident. This application addresses this issue by using a split-type car assembly 1. Driven by the electrical control device 3, in the event of an elevator accident, the device stops the first drive unit 21, keeping the first car 11 relatively stationary. Simultaneously, it operates the second drive unit 22, moving the second car 12 away from the first car 11, thus lowering passengers to the landing door of the next floor for safe evacuation. This also allows maintenance personnel to enter. The split-type car assembly 1, with the second car 12 moving relative to the first car 11, facilitates rapid passenger evacuation during an elevator accident, preventing further escalation and ensuring passenger safety. It also allows maintenance personnel to easily access the elevator for repairs.

[0027] The elevator car also includes a locking device 4 installed at the connection between the first car 11 and the second car 12 and electrically connected to the electronic control device 3. The second drive device 22 drives the second car 12 to move toward the first car 11 and make contact. The electronic control device 3 controls the locking device 4 to reset, thereby locking the first car 11 and the second car 12. When the elevator car does not need to be separated, the electronic control device 3 controls the first drive device 21 and the second drive device 22 to drive the first car 11 and the second car 12 at the same speed, so that the first car 11 and the second car 12 remain in a relatively stationary position. Due to the weight of the passengers and the weight of the second car 12, the locking device 4 is provided to share the pressure borne by the second drive device 22 and reduce the swaying between the first car 11 and the second car 12, thereby improving the overall riding comfort.

[0028] The locking device 4 includes a third drive device 41 mounted on the first car 11 or the second car 12, a buckle 42 fastened at the connection between the first car 11 and the second car 12, and a transmission rod 43 connecting the third drive device 41 and the buckle 42. The first car 11 and the second car 12 are respectively provided with a slot 5 for the buckle 42 to be inserted into, and a relief groove 6 provided adjacent to the slot 5. The third drive device 41 drives the buckle 42 to disengage from the slot 5 and move to the relief groove 6 to release the lock on the first car 11 and the second car 12. The output end of the third drive device 41 can be a gear or a pulley, and the transmission rod 43 can be a rack or a belt. In the event of an elevator accident, the third drive device 41 drives the buckle 42 to disengage from the slot 5 and move to the relief groove 6 through the transmission rod 43 to release the lock on the first car 11 and the second car 12.

[0029] The buckle 42 is provided with an assembly groove 44 with an opening facing the slot 5. The cross-section of the assembly groove 44 is "T" shaped so that the buckle 42 can be fastened to the slot 5. When the buckle 42 is fastened to the slot 5, the buckle 42's locking block is embedded in the slot 5 and fastened, which minimizes the risk of the buckle 42 coming off and makes it safer.

[0030] The elevator car also includes a first guide rail 7 installed in the elevator shaft at a diagonal location corresponding to the car assembly 1, and a roller assembly 8 installed at a diagonal location of the car assembly 1 to fit against the inner side of the first guide rail 7. When the second drive device 22 drives the second car 12 to separate from the first car 11, the roller assembly 8 presses against the inside of the first guide rail 7, reducing the gap between the car assembly 1 and the elevator shaft and improving the stability of the elevator car movement.

[0031] The elevator car also includes a stop device 9 installed on the second car 12. The stop device 9 includes a locking rod 91 slidably installed on the second car 12 and a fourth drive device 92 installed on the second car 12 and connected to the locking rod 91. The first guide rail 7 has a through hole 71 corresponding to the locking rod 91. The fourth drive device 92 drives the locking rod 91 to move and embed into the through hole 71, so that the second car 12 is stationary relative to the landing door device. The output end of the fourth drive device 92 can be equipped with a gear. The locking rod 91 has teeth on the side facing the fourth drive device 92 corresponding to the gear, reducing the probability of slippage between them. When the second drive device 22 drives the second car 12 to move to the landing door device, the fourth drive device 92 drives the locking rod 91 to penetrate into the through hole 71, thereby fixing the second car 12 and preventing shaking during passenger transfer, or even causing a secondary elevator accident.

[0032] The second car 12 is equipped with a handrail assembly 10 for passengers to hold onto. When the first car 11 and the second car 12 are combined, or when the first car 11 and the second car 12 are separated, passengers can hold onto the handrail assembly 10 to reduce the discomfort caused by elevator swaying.

[0033] The first drive device 21 includes a fixed frame 211 mounted around the periphery of the car assembly 1, a second guide rail 212 mounted in the elevator shaft for embedding the fixed frame 211, a first drive motor 213 mounted at the top of the elevator shaft, a counterweight device, a first traction rope 214 connecting the fixed frame 211 and the counterweight device, and a first roller transmission assembly 215 mounted on both sides of the first drive motor 213 to support the first traction rope 214. The first drive motor 213 is a reduction gearbox, and the fixed frame 211 includes a counterweight... With the connecting rods 216 on the upper and lower sides of the car assembly 1 and the telescopic rods 217 on the sides of the car assembly 1, the second drive device 22 drives the second car 12 to move away from the first car 11. The telescopic rods 217 extend to compensate for the relative height between the first car 11 and the second car 12. When the first drive motor 213 rotates and pulls the first traction rope 214, the swaying of the elevator car is reduced due to the restriction of the second guide rail 212, and a certain guiding effect is played on the elevator car.

[0034] The elevator car also includes a support base 23 installed at the top of the elevator shaft to fix the drive system 2. The second drive device 22 includes a second drive motor 221 installed at the top of the elevator shaft, a second traction rope 222 passing through the first car 11 at opposite corners and connected to the second car 12, and a second roller transmission group 223 respectively installed on the first car 11 and the support base 23 to support the second traction rope 222. The second roller transmission group 223 is provided to provide a certain support for the second traction rope 222, avoiding direct friction between it and the elevator car or support base 23, thereby damaging the second traction rope 222 and causing a fall. On the other hand, it corrects the direction of the second traction rope 222, minimizing the angle between the second traction rope 222 and the second drive motor 221 and the elevator car, and reducing the mutual tension between them.

[0035] In summary, this application has, but is not limited to, the following beneficial effects:

[0036] An elevator with a split-type elevator car according to the present invention includes: a car assembly 1, which includes a first car 11 and a second car 12 separately installed from the first car 11; a drive system 2, which is installed in the elevator shaft, including a first drive device 21 connected to the first car 11 and a second drive device 22 connected to the second car 12; and an electrical control device 3, which is electrically connected to the first drive device 21 and the second drive device 22 respectively. The electrical control device 3 controls the first drive device 21 to stop operating, and controls the second drive device 22 to operate. The second drive device 22 drives the second car 12 to move away from the first car 11 to the nearest landing door device. Existing elevator cars mainly use multiple car panels spliced ​​into a whole elevator car. When the elevator malfunctions, a few elevators can be climbed out through the passage at the top of the elevator car for self-rescue, while most elevators directly lock the elevator car, and the car door can only be pried open. Escape methods that rely on prying open the elevator car doors are problematic. Firstly, it's difficult to do this manually from inside the car, and specialized tools are often lacking. Secondly, the prying process can cause the elevator to shake, potentially leading to a more serious accident. This application addresses this by using a split-type car assembly 1. Driven by the electrical control device 3, in the event of an elevator accident, the device stops the first drive unit 21, keeping the first car 11 relatively stationary. Simultaneously, it controls the second drive unit 22 to move the second car 12 away from the first car 11, thus lowering passengers to the landing door of the next floor for safe evacuation. This also allows maintenance personnel to enter. The split-type car assembly 1, with the second car 12 moving relative to the first car 11, facilitates rapid passenger evacuation during an elevator accident, preventing further escalation and ensuring passenger safety. It also allows maintenance personnel to easily access the elevator for repairs.

[0037] The above description provides one or more embodiments in conjunction with specific content, and does not imply that the specific implementation of this application is limited to these descriptions.
