Technical Field

[0001] The utility model relates to the technical field of elevator installation and commissioning, and specifically relates to a simulation test device for elevator installation and commissioning. Background Technique

[0002] There are many types of elevators, and their control methods are different. However, the requirements and methods for commissioning should comply with the relevant regulations of the "Safety Code for the Manufacture and Installation of Elevators" and the "Acceptance Code for Elevator Installation" in China. For elevator manufacturers, whether an elevator can be qualified for factory shipment requires a simulation test before shipment. Through the simulation test, the various performances of the elevator are inspected to ensure that the elevator meets the application qualification standards.

[0003] The existing elevator simulation test device has a certain height. Although it can be extended and heightened to simulate different floor heights, when it is stored, there is a problem of difficult storage. The existing elevator simulation test device does not have the function of folding up and down, which results in the need for a sufficiently high space to store it, inconvenient storage, and troublesome handling at the same time.

[0004] Therefore, those skilled in the art have provided a simulation test device for elevator installation and commissioning to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to provide a simulation test device for elevator installation and commissioning to solve the problem that the existing elevator simulation test device cannot be folded up and down raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] A simulation test device for elevator installation and commissioning includes: a bottom plate. A pressure sensing base is fixedly arranged at the bottom of the bottom plate, and support feet are fixedly connected to the four corners of the lower surface of the bottom plate. A buffer groove is opened at the middle position of the upper surface of the bottom plate, and a buffer column is slidably installed inside the buffer groove. Semicircular grooves are arranged at the four corners of the upper surface of the bottom plate. A limit plate group is installed above each semicircular groove. The limit plate group includes a lower limit plate and an upper limit plate, and the upper limit plate is connected to the top of the lower limit plate. A connecting shaft is rotatably connected between the lower limit plate and the upper limit plate, and a torsion spring is sleeved outside the connecting shaft. Fixed blocks are fixedly connected to the outer side of the lower limit plate close to the bottom plate and the outer side of the upper limit plate close to the bottom plate, and movable grooves are opened on the end surfaces of the fixed blocks. An electric telescopic rod is connected between the two fixed blocks. An elevator car is placed above the buffer column, and a suspension cable connection box is arranged at the top of the elevator car. The top of the uppermost limit plate group is fixedly connected to a top plate, and a suspension cable winding box is arranged above the top plate. A suspension cable is connected between the suspension cable winding box and the suspension cable connection box.

[0008] As a solution in the present utility model, buffer springs are arranged on the inner sides of the buffer grooves, and the bottom ends of the buffer springs are in contact with the pressure sensing chips in the pressure sensing base.

[0009] As a solution in the present utility model, upper connecting pieces are fixedly connected to the top ends of the lower limiting plate and the upper limiting plate, and lower connecting pieces are fixedly connected to the bottom ends of the lower limiting plate and the upper limiting plate.

[0010] As a solution in the present utility model, the limiting plate groups are spliced end to end in the vertical direction. Connecting rods are horizontally arranged on the inner sides of the semi-circular grooves, and the lower connecting piece at the bottom end of the lowermost limiting plate group is rotationally connected to the bottom plate through the connecting rod.

[0011] As a solution in the present utility model, both ends of the electric telescopic rod are respectively rotationally connected in the movable groove, and the lower limiting plate and the upper limiting plate form an elastic rotation structure through a connecting shaft and a torsion spring.

[0012] As a solution in the present utility model, support plates are fixedly connected to the inner sides of the lower limiting plate and the upper limiting plate close to the bottom plate, and placement grooves are uniformly penetrated inside the support plates. Rubber rollers are rotationally installed inside the placement grooves.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. A plurality of limiting plate groups can be connected in the vertical direction to adjust the height of the entire device, simulate different floor heights, and the limiting plate groups can be folded through the electric telescopic rod. In this way, the entire device can be folded in the Z-axis direction without removing the limiting plate groups, directly reducing the height of the entire device, making it more convenient and fast to store and place the device, and enabling good storage. Reducing the height can also lower the center of gravity, making the device more stable and less likely to shake during movement, ensuring safe movement.

[0015] 2. By setting the buffer springs, the elevator car descends smoothly, avoiding derailment and dropping of the elevator car or damage caused by too fast a falling speed. Moreover, the buffer springs can directly transfer the pressure to the pressure sensor components in the pressure sensing base to form pressure data. By analyzing and judging this pressure data, it can be determined whether the current falling speed is appropriate, whether the elevator car lands smoothly, and the falling pressure change range of the elevator car at this speed can be obtained.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 5 , the embodiments of the present invention provide a simulation test device for elevator installation and commissioning, including: a bottom plate 1, a pressure sensing base 2 is fixedly arranged at the bottom of the bottom plate 1, and support feet 3 are fixedly connected to the four corners of the lower surface of the bottom plate 1. A buffer groove 4 is opened at the middle position of the upper surface of the bottom plate 1, and a buffer column 6 is slidably installed inside the buffer groove 4. Buffer springs 5 are arranged inside the buffer groove 4, and the bottom ends of the buffer springs 5 are in contact with the pressure sensing chips inside the pressure sensing base 2;

[0024] Specifically, the buffer column 6 is slidably assembled inside the buffer groove 4, and its bottom contacts the buffer spring 5. When the elevator car 21 descends to the lowest position, the elevator car 21 presses the buffer column 6, causing the buffer column 6 to penetrate into the buffer groove 4, and then causing the buffer spring 5 to contract. This not only plays a role in buffering and protecting the elevator car 21, but also the buffer spring 5 transfers the pressure to the pressure sensing chip inside the pressure sensing base 2, forming pressure data through the pressure sensing component inside the pressure sensing base 2. The pressure data is transmitted to the processor in real time. By analyzing whether the change of the pressure data is regular during the descent of the elevator car 21, it is possible to check whether the elevator car 21 lands smoothly, whether it can meet the standard of safe landing, and the pressure change range of the elevator car 21 at different descending speeds, so as to help reasonably limit the lifting speed of the elevator car 21;

[0025] Semicircular grooves 7 are provided at the four corner positions of the upper surface of the bottom plate 1. Limiting plate groups are installed above the semicircular grooves 7. The limiting plate group includes a lower limiting plate 8 and an upper limiting plate 9, and the upper limiting plate 9 is connected to the top of the lower limiting plate 8. Upper connecting pieces 10 are fixedly connected to the tops of the lower limiting plate 8 and the upper limiting plate 9, and lower connecting pieces 11 are fixedly connected to the bottoms of the lower limiting plate 8 and the upper limiting plate 9. The limiting plate groups are spliced end to end in the vertical direction. Connecting rods 12 are horizontally arranged inside the semicircular grooves 7, and the lower connecting piece 11 at the bottom of the lowermost limiting plate group is rotatably connected to the bottom plate 1 through the connecting rod 12. A connecting shaft 13 is rotatably connected between the lower limiting plate 8 and the upper limiting plate 9, and a torsion spring 14 is sleeved outside the connecting shaft 13. Fixed blocks 15 are fixedly connected to the outer side of the lower limiting plate 8 close to the bottom plate 1 and the outer side of the upper limiting plate 9 close to the bottom plate 1, and movable grooves 16 are formed on the end surfaces of the fixed blocks 15. An electric telescopic rod 17 is connected between the two fixed blocks 15. Both ends of the electric telescopic rod 17 are respectively rotatably connected in the movable grooves 16, and the lower limiting plate 8 and the upper limiting plate 9 form an elastic rotating structure through the connecting shaft 13 and the torsion spring 14;

[0026] Specifically, the limit plate group is arranged at the four corners above the bottom plate 1 to limit the up and down movement range of the elevator car 21 and to straighten and support the elevator car 21. Multiple limit plate groups can be connected end to end in the vertical direction, so that the height of the entire simulation test device can be extended to meet the test requirements of different floor heights. The limit plate group is composed of a lower limit plate 8 and an upper limit plate 9. The lower limit plate 8 and the upper limit plate 9 are directly connected by a lower connecting piece 11 and an upper connecting piece 10. At the same time, the limit plate group is rotationally connected to the bottom plate 1 by the lower connecting piece 11. That is to say, the limit plate group can rotate on the bottom plate 1, and the lower limit plate 8 and the upper limit plate 9 form a rotational structure through a connecting shaft 13. Therefore, the lower limit plate 8 and the upper limit plate 9 can also rotate relative to each other. In this way, the limit plate group can be bent to realize the folding of the entire simulation test device in the Z-axis direction, so as to facilitate the storage and placement of the simulation test device. The electric telescopic rod 17 folds or unfolds the limit plate group through electric telescoping. The electric telescopic rod 17 is installed on the outer side of the lower limit plate 8 and the upper limit plate 9. When the electric telescopic rod 17 contracts, the lower limit plate 8 and the upper limit plate 9 fold inward. When the electric telescopic rod 17 extends, the lower limit plate 8 and the upper limit plate 9 are pulled outward. At the same time, the lower limit plate 8 and the upper limit plate 9 have strong rotational elasticity by using a torsion spring 14. In this way, when the electric telescopic rod 17 extends, the lower limit plate 8 and the upper limit plate 9 can be better pulled apart and can maintain a certain vertical strength after being pulled apart to ensure the smooth operation of the elevator car 21;

[0027] On the inner side of the lower limit plate 8 close to the bottom plate 1 and on the inner side of the upper limit plate 9 close to the bottom plate 1, a support plate 18 is fixedly connected, and a placement groove 19 is uniformly penetrated inside the support plate 18. A rubber roller 20 is rotatably installed inside each placement groove 19;

[0028] Specifically, the support plate 18 is used to limit the elevator car 21 so that the elevator car 21 can only move up and down between the four groups of limit plate groups. A rotatable rubber roller 20 is provided on the support plate 18 to reduce the friction between the support plate 18 and the elevator car 21, so that the elevator car 21 can move up and down smoothly and stably, and while ensuring the stability of the lifting, the influence on the pressure data is minimized as much as possible;

[0029] An elevator car 21 is placed above the buffer column 6, and a sling connection box 22 is arranged at the top of the elevator car 21. The top of the uppermost limit plate group is fixedly connected with a top plate 23, and a sling winding box 24 is arranged above the top plate 23. A sling 25 is connected between the sling winding box 24 and the sling connection box 22.

[0030] The working principle of the present invention is:

[0031] The elevator car 21 is placed inside four groups of limit plates. The outer walls of the elevator car 21 are respectively in contact with the rubber rollers 20 inside the support plates 18. Combining with the test requirements, multiple groups of limit plates are assembled in the vertical direction to raise the entire simulation test device to a suitable height. Then, the elevator car 21 can be operated normally. The elevator car 21 is pulled up or down by the sling 25. When the elevator car 21 descends to the lowest position, the elevator car 21 will first contact the buffer column 6 and press down the buffer column 6, forcing the buffer spring 5 below the buffer column 6 to contract. The buffer spring 5 buffers the pressure and transfers the pressure to the pressure sensing piece inside the pressure sensing base 2 to form pressure data. Then, the pressure data is analyzed to see if the pressure data changes regularly during the descent of the elevator car 21. If the change is regular, it indicates that the elevator car 21 lands stably at this speed. After the simulation test is completed, the simulation test device needs to be folded. The electric telescopic rod 17 is directly started to make the electric telescopic rod 17 contract. In this way, the upper limit plate 9 and the lower limit plate 8 respectively connected to both ends of the electric telescopic rod 17 will fold towards the inside of the simulation test device. The lower limit plate 8 at the bottom of the simulation test device will also tilt towards the inside of the simulation test device under the action of the connecting rod 12, that is, the limit plate group folds in a zigzag shape, so that the height of the simulation test device can be quickly reduced and it can be received in a lower factory building without having to remove the limit plate group.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
