Description

Technical Field

[0001] The present invention relates to the technical field of elevators.

[0002] In particular, the present invention relates specifically to an elevator shaft signal simulation device. Background Art

[0003] Elevators are being used more and more widely in various buildings. The reliability and safety of elevators are closely related to the life safety of passengers, so elevators need to be equipped with a large number of safety detection and safety protection devices. These safety devices are often strictly inspected before leaving the factory. Among them, the elevator shaft signal is an important component to ensure the accurate arrival of the elevator. Therefore, during the operation of the elevator, the signal simulation of the elevator shaft is particularly important.

[0004] For example, Chinese utility model patent CN201567125U discloses an elevator shaft signal simulator, including a control panel, the control panel including a microcomputer controller and a frequency converter connected in series with each other, the control panel is connected to a motor and a coaxial encoder in turn through the frequency converter, the frequency converter and the coaxial encoder are connected in series with each other, and the control panel is connected in series with an analog single-chip microcomputer through the microcomputer controller; the control panel is respectively connected to an inner call plate, an outer call plate and a safety circuit switch, and the inner call plate and the outer call plate are connected in parallel with each other; the motor plus the encoder simulates the rotation of the traction machine to provide a car running signal, the single-chip microcomputer receives the control panel command and the encoder pulse and then synthesizes the shaft position signal, and simulates the door machine action and the door position signal, and cooperates with the switch, inner call plate and outer call plate of the simulated safety circuit, so as to conveniently realize the full function inspection of the elevator control panel.

[0005] However, the above simulator only uses encoders and single-chip microcomputers to simulate shaft signals. In fact, the shaft signal components are installed in the shaft from the highest floor to the lowest floor of the elevator. The installation occupies a large space, and the distance between the components is far, which is very inconvenient for the testing and debugging of these components.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable elevator shaft signal simulation device. Summary of the invention

DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0026] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangements of modules and structures set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

[0027] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0028] Technologies, methods, and systems known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0029] Embodiment 1: Figure 1 , 2The figure is only one of the embodiments of the present invention, an elevator shaft signal simulation device, including a deceleration part, a floor simulation part and an end station simulation part, the deceleration part includes a driven wheel 2 connected to the traction machine 17 through a belt 1, a driving shaft 4 connected to the driven wheel 2 and a reduction box 6 connected to the driving shaft 4 through a coupling 5, the reduction box 6 is provided with an output shaft 7, the floor simulation part includes a rotating disk connected to the output shaft 7, a floor signal board 8 arranged on the rotating disk and a leveling signal switch 9 connected to the floor signal board 8, the end station simulation part includes a lead screw 15 connected to the output shaft 7, a working platform 12 arranged on the lead screw 15 and a track 14 for facilitating the sliding of the working platform 12, a deceleration magnet 11 and a limit impact bow 10 are arranged at the end of the working platform 12, and a forced deceleration switch 13 extending in the direction of the deceleration magnet 11 and a limit switch 16 extending in the direction of the limit impact bow 10 are arranged on the outer side of the track 14.

[0030] In the present invention, the deceleration part is directly connected to the traction machine 17, and the deceleration part includes a driven wheel 2 connected to the traction machine 17 through a belt 1, a driving shaft 4 connected to the driven wheel 2, and a reduction box 6 connected to the driving shaft 4 through a coupling 5. The reduction box 6 is provided with an output shaft 7. The traction machine 17 drives the elevator car to move. The traction machine 17 also transmits the rotation to the reduction box 6 for deceleration. The reduction box 6 then outputs the decelerated rotation through the output shaft 7. In this way, the vertical movement of the elevator can be converted into the circular movement of the output shaft 7, and the high-speed movement of the elevator can be effectively reduced to low-speed movement through the deceleration operation.

[0031] Then comes the floor simulation part. The rotating disk of the floor simulation part is connected to the output shaft 7 and rotates driven by the output shaft 7. The floor signal plate 8 on the rotating disk rotates, and then when it passes through the leveling signal switch 9, it indicates that the elevator car has just run one floor.

[0032] It should be noted that the leveling signal switch 9 can also calculate the floor where the elevator is located. For example, every time a floor signal plate 8 passes through the leveling signal switch 9 clockwise, the floor where the elevator car is located is increased by one; conversely, every time a floor signal plate 8 passes through the leveling signal switch 9 counterclockwise, the floor where the elevator car is located is reduced by one.

[0033] Finally, there is the terminal simulation part. When the elevator car runs to the top or bottom of the shaft, it needs to slow down or even stop moving to prevent the car from falling down too fast or hitting the top when going up too fast. The terminal simulation part includes a screw rod 15 connected to the output shaft 7, a working platform 12 arranged on the screw rod 15, and a track 14 for facilitating the sliding of the working platform 12. The end of the working platform 12 is provided with a deceleration magnetic steel 11 and a limit impact bow 10. The outer side of the track 14 is provided with a forced deceleration switch 13 extending in the direction of the deceleration magnetic steel 11 and a limit switch 16 extending in the direction of the limit impact bow 10. When the deceleration magnetic steel 11 approaches the forced deceleration switch 13, the traction machine 17 starts to force deceleration to reduce the running speed of the elevator car. When the limit impact bow 10 contacts the limit switch 16, the traction machine 17 stops running immediately. Stop the elevator car to ensure the safety of the elevator operation.

[0034] In short: the traction machine 17 drives the driven wheel 2 to rotate through the belt 1, and then transmits it to the reduction box 6 through the driving shaft 4. After deceleration, it drives the floor signal plate 8 to rotate through the output shaft 7. Each floor signal plate 8 passes through the leveling signal switch 9 once, which means that the elevator car has reached a floor. While the output shaft 7 drives the floor signal plate 8 to rotate, it drives the working platform 12 to run along the track 14 through the lead screw 15. When the deceleration magnet 11 approaches the forced deceleration switch 13, the traction machine 17 starts to be forced to decelerate. When the limit collision bow 10 contacts the limit switch 16, the traction machine 17 stops running immediately.

[0035] An elevator shaft signal simulation device of the present invention is designed to convert the vertical movement of the elevator into circular movement, and then reduce the high-speed movement of the elevator to low-speed movement through a deceleration system, so that all components of the elevator shaft signal system can be installed in a very small space, and the electrical components of the elevator can be tested and debugged very conveniently and quickly.

[0036] Embodiment 2: Still as Figure 1 , 2 The figure is only one of the embodiments of the present invention. Compared with the above embodiments, in this example, a support base is provided under the deceleration unit, the floor simulation unit and the terminal simulation unit. The support base is provided at the bottom or top of the elevator shaft, close to the traction machine 17, and the support base ensures the stable operation of the entire simulation device.

[0037] Then, the driving shaft 4 is provided with a bearing seat 3 for supporting the driving shaft 4 , and the bearing seat 3 ensures that the driving shaft 4 can be stably connected to the rotation axis of the driven wheel 2 .

[0038] Furthermore, the output shaft 7, the rotating disk and the screw rod 15 are coaxially arranged.

[0039] Then, the number of the floor signal plate 8 is at least one, and they are evenly arranged outside the rotating disk.

[0040] Of course, at least a part of the floor signal plate 8 is arc-shaped. Since the floor signal plate 8 rotates to pass through the leveling signal switch 9, in order to ensure that the floor signal plate 8 will not be stuck in the leveling signal switch 9, it is necessary to ensure that the contact part between the floor signal plate 8 and the leveling signal switch 9 has a certain curvature, and the radius of the curvature should be the distance between the contact position of the floor signal plate 8 and the leveling signal switch 9 and the axis of the rotating disk.

[0041] In addition, the working platform 12 and the screw rod 15 are vertically arranged, and a connecting tube is fixedly arranged on the working platform 12. At least a part of the screw rod 15 is located in the connecting tube. An external thread is arranged on the outer side of the screw rod 15, and an internal thread is arranged in the connecting tube. The screw rod 15 rotates under the drive of the output shaft 7, and the working platform 12 is rotationally connected with the screw rod 15. When the screw rod 15 rotates, the working platform 12 slides along the track 14. It should be noted that the number of the tracks 14 is at least one, and the track 14 also serves to limit the working platform 12 and prevent the working platform 12 from following the rotation of the screw rod 15.

[0042] In addition, the number of the deceleration magnet 11 and the limit striker 10 is at least one. Generally speaking, a deceleration magnet 11 is provided at each end of the working platform 12, and a limit striker 10 is provided on each side of the deceleration magnet 11. When any one of the deceleration magnets 11 at both ends of the working platform 12 contacts the forced deceleration switch 13, the traction machine 17 decelerates; and a limit striker 10 is provided on each side of the deceleration magnet 11, so that no matter in which direction the working platform 12 moves, it can be ensured that the limit striker 10 and the limit switch 16 are in contact.

[0043] Finally, the number of the forced deceleration switch 13 and the limit switch 16 is at least one, and a forced deceleration switch 13 and a limit switch 16 are provided at both ends of the track 14, just simulating the elevator car running to the top and bottom of the shaft.

[0044] An elevator shaft signal simulation device of the present invention is designed to convert the vertical movement of the elevator into circular movement, and then reduce the high-speed movement of the elevator to low-speed movement through a deceleration system, so that all components of the elevator shaft signal system can be installed in a very small space, and the electrical components of the elevator can be tested and debugged very conveniently and quickly.

[0045] The above-described embodiments are only descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents for which protection is sought in the present invention have been fully recorded in the claims.
