Description

Technical Field

[0001] This utility model belongs to the field of elevator technology, specifically relating to a passenger elevator base protection device. Background Technology

[0002] In the process of modern urbanization, high-rise buildings have sprung up like mushrooms after rain. As a vertical transportation tool connecting different floors, the safety and reliability of passenger elevators have become the focus of attention. The operating system of passenger elevators is complex and precise, involving multiple aspects such as electrical control, mechanical transmission, and safety protection. Among them, the passenger elevator base protection device is a key part of the safety system and plays an irreplaceable role in preventing elevator accidents and protecting the lives of passengers.

[0003] Traditional passenger elevator designs are equipped with basic base protection devices, such as buffers and limit switches. However, these devices still need improvement in terms of buffering effect and passenger protection when faced with extreme situations, such as the car falling freely due to the breakage of the steel wire rope. Especially in the field of high-speed elevators and heavy-duty elevators, due to the large mass of the car and the high falling speed, traditional base protection devices are often unable to effectively absorb the huge impact energy in a short period of time, which may result in serious injury to the car and passengers.

[0004] To address the aforementioned issues, the industry has undertaken numerous explorations and innovations. For example, a convenient elevator base device, patent publication number CN220976223U, reduces the frequency of pedal movement by introducing telescopic components and dampers, thereby improving the stability of elevator operation to a certain extent. However, this patent mainly focuses on the ease of installation and smooth operation of the elevator base, and does not adequately consider the emergency braking and energy absorption capabilities of the elevator in the event of a sudden malfunction.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figures 1-3 This is the first embodiment of the present invention, which provides a passenger elevator base protection device, including...

[0025] The support plate 5 has multiple equally spaced fixing cylinders 51 on its top, which realizes the addition of fixing cylinders 51, and a first spring is installed at the bottom of the inner part of the fixing cylinder 51, which realizes the addition of the first spring.

[0026] The bottom of the pedal 6 is provided with multiple first dampers 61 that can extend into the fixed cylinder 51, and one end of the first damper 61 is connected to the first spring. When the elevator malfunctions and the speed drops too fast, the person above the pedal 6 will exert more pressure on the pedal 6 than normal. The pedal 6 will drop and squeeze the first damper 61. At the same time, with the cooperation of the first spring, the movement of the pedal 6 will be reduced, thereby making the person on the pedal 6 more stable.

[0027] The shock absorption assembly includes a protective seat 2, a receiving groove 22 opened at the top of the protective seat 2, a second damper 4 extending into the receiving groove 22 at one end, and a horizontal plate 42 connected to the support plate 5 at the other end. A second spring 220 is installed at the bottom of the receiving groove 22 and connected to the embedded end face of the second damper 4. When the support plate 5 moves, the cooperation of the second damper 4 and the second spring 220 achieves more efficient absorption and dispersion of the energy of the car falling, providing more reliable safety for passengers.

[0028] In this embodiment, preferably, a guide rod 221 installed at the bottom of the receiving groove 22 is also included, thus adding the guide rod 221. An extension plate 41 is provided on the side surface of the second damper 4, thus adding the extension plate 41. A guide hole 410 is opened inside the extension plate 41 for the guide rod 221 to pass through. The cooperation of the guide rod 221 and the guide hole 410 increases the guidance of the second damper 4 when it moves.

[0029] In this embodiment, preferably, a stop is installed on the top of the guide rod 221 to limit the guide rod 221. The protective seat 2 has a groove 23 inside for the extension plate 41 to slide. The sliding of the extension plate 41 in the groove 23 increases the smoothness of the second damper 4's movement.

[0030] In this embodiment, preferably, a base frame 1 is installed at the bottom of the protective seat 2, and fasteners 3 are symmetrically distributed on the base frame 1. The fasteners 3 are connected to the protective seat 2 by bolts, and the base frame 1 and the protective seat 2 are stably spliced ​​by the fasteners 3. Example

[0031] Please see Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0032] The protective base 2 has a maintenance opening on its side surface to improve maintenance performance. A protective plate 21 is hinged to the side surface of the protective base 2 outside the maintenance opening. The protective plate 21 can be opened and closed, increasing ease of use. A slot 210 is provided on the side surface of the protective plate 21. A fastening plate 24 is installed on the side surface of the protective base 2, and a through hole 240 is provided inside the fastening plate 24. A third spring 241 is provided on the side surface of the fastening plate 24. Furthermore, one end of the third spring 241 is connected to a pull plate 7. The third spring 241 is connected to the fastening plate 24 and the pull plate 7 respectively. The pull plate 7 is provided with a through hole 240 and a rod 8 that can be inserted into the slot 210. When it is necessary to open the guard plate 21, the pull plate 7 can be pulled to move the rod 8. When the rod 8 is disengaged from the inside of the slot 210, the guard plate 21 can be opened quickly. When the rod 8 is inserted into the inside of the slot 210, the closing performance of the guard plate 21 is increased. A pull ring 71 is installed at the end of the pull plate 7 to increase the convenience of pulling the pull plate 7.

[0033] The working principle and usage process of this utility model are as follows: When the elevator is running normally, the person on the step 6 applies pressure to the step 6 normally, and the step 6, the support plate 5 and the entire device are in a relatively stable state, and no special action is produced by each component.

[0034] When the elevator malfunctions and drops too quickly, the person above step 6 will exert more pressure on step 6 than normal. As step 6 descends, it compresses the first damper 61. At the same time, the first spring reduces the movement of step 6, making the person on step 6 more stable. Meanwhile, the support plate 5 moves, causing the second damper 4 to move. The second damper 4 and the second spring 220 work together to absorb and disperse the energy of the car falling more efficiently, providing reliable safety for passengers.

[0035] When maintenance is required, pull the pull ring 71 at the end of the pull plate 7 to move the pull plate 7. The insertion rod 8 on the pull plate 7 disengages from the slot 210 on the side surface of the guard plate 21. At this time, the guard plate 21, which is hinged to the side surface of the protective seat 2, can be opened, and maintenance operations can be performed through the maintenance port opened on the side surface of the protective seat 2. After maintenance is completed, close the guard plate 21 and release the pull plate 7. Under the action of the third spring 241, the insertion rod 8 is inserted into the slot 210, so that the guard plate 21 is closed and kept stable.

[0036] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
