Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a novel elevator car. Background Art

[0002] With the rapid development of society and the aging of the population, elevators have gradually become an indispensable part of people's work and life. In particular, there are higher requirements for the installation and shaft space of elevators. In the prior art, the escape windows of elevators are mostly set up in a flip-opening manner, which has a high demand for the space above the car top and has an adverse effect on the installation of elevators.

[0003] In a Chinese patent document with publication number CN105565119B and titled "An Elevator Car Rescue Device", it is disclosed that one end of its safety escape window is rotatably connected to the car top, and the car top is also provided with an automatic opening device that drives the safety escape window to rotate and open to an upright state. The automatic opening device is a pneumatic pull rod connected between the safety escape window and the car top and has an automatic extension tendency. A pneumatic pull rod is connected to the left and right sides of the automatic safety window respectively. When the safety window lock is opened, the safety escape window will automatically open to an upright state under the action of the pneumatic pull rod. The escape window is rotatably connected to the car top and needs to be lifted up to open when in use, which requires a large installation space on the car top. It has high requirements for the structural layout and space above the car top when the elevator is installed, and the use of the car top space is unreasonable. Utility Model Content

[0004] The utility model aims to provide a novel elevator car, which reduces the space requirement when the escape window is opened and reduces the space requirement above the car top when the elevator is installed.

[0005] In order to solve the above technical problems, the implementation method of the utility model provides a technical solution as follows:

[0006] A novel elevator car comprises a car body, a car roof is provided on the top of the car body, an escape hole is provided on the car roof, and an escape window is arranged to match the escape hole, a movable part is provided on the side of the escape window facing the car body, a guide rail is provided on the side of the car roof facing away from the car body, and the movable part can slide along the guide rail to open or close the escape hole.

[0007] Furthermore, a limiting member is provided on the guide rail, and the limiting member can stop and limit the moving part along the axial direction of the guide rail.

[0008] Furthermore, a limiting member is respectively provided at both ends of the guide rail, and when the escape window is in an open state, the moving part is located between the two limiting members.

[0009] Further, the moving part is a roller, the roller is arranged corresponding to the limiting part, and the axial distance between the rollers along the guide rail is less than the axial distance between the limiting parts along the guide rail.

[0010] Further, there are two guide rails, and the two guide rails are arranged in parallel.

[0011] Further, when the escape window closes the escape hole, the moving part is separated from the guide rail.

[0012] Further, a triangular lock and a locking part for restricting the relative displacement between the escape window and the car top are provided on the car top.

[0013] Further, the locking part includes a first hydraulic column and a second hydraulic column perpendicular to the car top, and one ends of the first hydraulic column and the second hydraulic column are connected by a connecting rod.

[0014] A new type of elevator car provided by the present invention, compared with the prior art, through the separated guide rail and moving part, and the setting that the moving part can slide along the guide rail to open or close the escape hole, enables the escape window to be opened in a translational manner, saving the installation space on the car top. At the same time, by setting the limiting parts on the guide rail, when the escape hole is in the open state, the horizontal displacement of the escape window is restricted, so as to prevent the escape window from having an unrestricted displacement when the escape hole is open, and increase the safety during rescue.

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will elaborate on each implementation manner of the present utility model in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each implementation manner of the present utility model, many technical details are proposed for the readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation manners, the technical solutions claimed in each claim of the present application can still be implemented.

[0024] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present application, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0025] As Figure 1-6 shown, the present utility model provides a new elevator car, including a car body. A car top is provided at the top of the car body. An escape hole 9 is provided on the car top, and an escape window 4 adapted to the escape hole 9 is provided. A moving part 6 is provided on the side of the escape window 4 facing the inside of the car body. A guide rail 7 is provided on the side of the car top away from the inside of the car body. The moving part 6 can slide horizontally along the guide rail 7 to open or close the escape hole 9.

[0026] In one embodiment, the car top includes an intermediate car top 3 provided with an escape hole 9, and a first car top 1 and a second car top 2 provided on both sides of the intermediate car top 3. The escape window 4 is installed on the car top composed of the first car top 1, the second car top 2 and the intermediate car top 3. A triangle lock 10 is provided at one end of the escape window 4, and a locking member 5 is linked with the triangle lock 10. Whether the triangle lock 10 is unlocked can drive the locking member 5 to displace, so as to open or limit the displacement of the safety window. In an exemplary example, the locking member 5 includes a first hydraulic column 51 and a second hydraulic column 52 perpendicular to the car top. The tops of the first hydraulic column 51 and the second hydraulic column 52 are connected by a connecting rod 53. Of course, the locking member 5 can also adopt mechanical structures such as linkages in the prior art to lock the escape window 4.

[0027] As Figure 2-3 shown, when the escape window 4 is in the locked state, the second hydraulic column 52 presses on the escape window 4, so that the escape window 4 is fixedly connected to the intermediate car top 3, preventing relative displacement between the escape window 4 and the intermediate car top 3 during the operation of the elevator.

[0028] As Figure 4 shown, this is a three-dimensional view of the unlocking state of the new elevator car escape window in an embodiment of the present invention. When the escape window 4 needs to be opened, use a triangular key or a pick to open the triangular lock 10, so that the second hydraulic column 52 rotates around the first hydraulic column 51 and leaves the projection range of the escape window 4 in the vertical direction. The vertical limit between the escape window 4 and the intermediate car top 3 is released. At this time, the escape window 4 is in the unlocked state. As Figure 5 shown, the rescue personnel can drag the escape window 4 along the direction perpendicular to the car top, so that the moving part 6 of the escape window 4 enters the guide rail 7, and then translate the escape window 4. The escape window 4 is in the open state, so that the escape hole 9 is in the open state.

[0029] As Figure 6 shown, in one embodiment, a limiting member 8 is provided in the guide rail 7. The limiting member 8 can block and limit the moving part 6 in the horizontal direction when the moving part 6 moves along the guide rail 7. Preferably, a limiting member 8 is provided at each end of the guide rail 7. When the escape window 4 is in the open state, the moving part 6 is located between the two limiting members 8, so that the movement of the escape window 4 at both ends along the axis of the guide rail 7 can be blocked and limited, effectively preventing the escape window 4 from shifting during the rescue process and increasing the safety during the rescue.

[0030] In an exemplary example, there are two guide rails 7, and the two guide rails 7 are arranged in parallel. The distance between the two parallel guide rails 7 is slightly smaller than the span corresponding to the escape window 4. A limiting member 8 is provided at each end of each guide rail 7. The moving part 6 of the escape window 4 corresponding to each guide rail 7 is a roller, and the roller is connected to the guide rail 7 in a rolling or sliding manner. The roller is arranged corresponding to the limiting member 8. The distance between the two limiting members 8 on each guide rail 7 is slightly larger than the distance between the corresponding rollers. In the open state of the escape window 4, the roller is accommodated in the guide rail 7, and the roller is located between the limiting members 8, so that the limiting member 8 can block and limit the roller in the axial direction of the guide rail 7, thereby preventing the escape window 4 from having unrestricted displacement in the open state and causing safety hazards in the rescue.

[0031] After the rescue is completed, drag the escape window 4 perpendicular to the car top direction, so that the roller moves vertically over the limit piece 8 and then translates to cover the escape hole 9. The escape window 4 returns to its original position, the triangular lock 10 is locked, and the locking piece 5 locks the escape window 4 to maintain the fixed connection between the escape window 4 and the car top.

[0032] A new type of elevator car provided by the present utility model, through the separated guide rail and moving part, and the arrangement that the moving part can slide along the guide rail to open or close the escape hole, enables the escape window to be opened in a translational manner, saving the installation space at the top of the car. At the same time, by setting a limit piece on the guide rail, when the escape hole is in the open state, the horizontal displacement of the escape window is restricted, so as to prevent the escape window from having an unrestricted displacement when the escape hole is open, increasing the safety during rescue.

[0033] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present utility model, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present utility model.
