Technical Field
[0001] This utility model relates to the field of elevator component technology, and in particular to an elevator pit installation structure. Background Technology
[0002] In modern buildings, elevators are crucial equipment for vertical transportation, and their safety and stability are paramount. The elevator pit, as an important component of the elevator system, serves multiple functions, including buffering the impact of a falling elevator car, securing the elevator guide rails, and protecting the elevator equipment from groundwater and foreign objects. The installation structure of the elevator pit directly affects the overall performance and lifespan of the elevator.
[0003] Current common elevator pit installation structures have several shortcomings. Some traditional installation structures are poorly designed for shock absorption, often employing simple rubber pads or rigid connections. When the elevator car unexpectedly falls, this simple shock absorption method cannot effectively absorb the impact, easily leading to damage to the elevator equipment and pit structure due to excessive impact, thus affecting the elevator's safety and lifespan. Regarding structural stability, some existing installation structures do not fix the guide rails precisely and securely enough, failing to adapt well to different models and specifications of elevator guide rails. This causes the guide rails to wobble during elevator operation, affecting the smoothness and safety of the elevator. Furthermore, existing installation structures have deficiencies in waterproofing and drainage. Some pits only use a single waterproofing measure, such as laying only a waterproof layer. When the groundwater level is high or water accumulates in the pit, it cannot be drained effectively and promptly, easily leading to moisture damage to the elevator equipment and affecting normal elevator operation. These problems urgently necessitate a new type of elevator pit installation structure to address these shortcomings, improve the elevator pit's shock absorption performance, structural stability, and waterproofing and drainage capabilities, and ensure the safe and stable operation of the elevator.
[0004] In response to this technical problem, this application proposes an elevator pit installation structure. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an elevator pit installation structure that provides overall shock absorption for the device, prevents impact from contact with the elevator bottom during use, thus improving the device's lifespan, increasing the overall structural stability, preventing shaking when the device engages with the elevator guide rails, thereby enhancing the stability of the pit installation, increasing structural stability, and improving pit protection.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An elevator pit installation structure includes a first top plate, a first bottom plate connected to the bottom side of the first top plate via a shock-absorbing component, a second top plate fixedly connected to the bottom side of the first top plate, four fixing brackets fixedly connected to the bottom side of the second top plate, the second bottom plate fixedly connected to the bottom side of the fixing brackets, the bottom side of the second bottom plate fixedly connected to the top side of the first bottom plate, fixing plates connected to the left and right sides of the first top plate via limiting components, slide rails fixedly connected to the adjacent sides of the two fixing plates, and two mounting blocks fixedly connected to the front sides of the first bottom plate.
[0008] Furthermore, the shock-absorbing component includes four fixed columns fixedly connected to the top side of the first base plate. Each of the four fixed columns has a groove on its top side. A damping rod is slidably connected to the top of the groove, and a spring is provided at the bottom of the groove.
[0009] Furthermore, the limiting component includes two mounting brackets that are fixedly connected to the left and right sides of the first top plate and the left and right sides of the first bottom plate. The mounting brackets are slidably connected to limiting posts inside, and the outer walls of the limiting posts are provided with two limiting grooves. The front sides of the mounting brackets are rotatably connected to rotating shafts, and the outer walls of the two rotating shafts are fixedly connected to limiting plates.
[0010] Furthermore, one end of the spring is connected to the bottom side of the damping rod, and the other end is connected to the bottom side of the groove.
[0011] Furthermore, a fixing layer is provided on the adjacent side of each of the two mounting brackets, and a limiting hole is opened inside the mounting bracket. The outer wall of the limiting post is slidably connected to the inner wall of the limiting hole, and the bottom side of the two limiting plates is in contact with the bottom side of the limiting groove.
[0012] Furthermore, a pressure sensor is provided on the top side of the second base plate.
[0013] Furthermore, each of the four mounting blocks has a mounting hole on its top side, and the mounting hole penetrates the interior of the mounting block.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, the damping rod slides and extends inside the fixed column, causing the spring to undergo elastic deformation, thereby achieving shock absorption of the entire device and preventing the impact caused by the contact with the bottom of the elevator during the use of the device from affecting its overall structure, thus improving the service life of the device.
[0016] 2. In this utility model, by rotating the limiting plate on the outer wall of the rotating shaft to engage with the limiting groove on the limiting column, the overall structural stability of the device is increased, avoiding shaking when the device engages with the elevator guide rail, thus affecting the stability of the pit installation, increasing structural stability, and increasing the pit protection effect.

[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.
[0024] Reference Figure 1 and Figure 2This utility model provides an embodiment of an elevator pit installation structure, including a first top plate 1. A first bottom plate 5 is connected to the bottom side of the first top plate 1 via a damping rod 19. A second top plate 12 is fixedly connected to the bottom side of the first top plate 1. Four fixing brackets 7 are fixedly connected to the bottom side of the second top plate 12. A second bottom plate 10 is fixedly connected to the bottom side of the fixing brackets 7. The bottom side of the second bottom plate 10 is fixedly connected to the top side of the first bottom plate 5. Fixing plates 3 are connected to both the left and right sides of the first top plate 1 via limiting posts 14. Slide rails 2 are fixedly connected to the adjacent sides of the two fixing plates 3. Two mounting blocks 11 are fixedly connected to both sides of the front side of the first bottom plate 5. One end of a spring 21 is connected to the bottom side of the damping rod 19, and the other end is connected to the bottom side of the slide rail 20. Fixing layers 13 are provided on the adjacent sides of the two mounting brackets 4. Limiting holes 17 are opened inside the mounting brackets 4. The outer wall of the limiting post 14 is slidably connected to the inner wall of the limiting hole 17. The bottom sides of the two limiting plates 16 are in contact with the bottom sides of the limiting grooves 18. A pressure sensor 9 is installed on the top side of the second base plate 10. Mounting holes 8 are provided on the top sides of all four mounting blocks 11, and the mounting holes 8 penetrate the interior of the mounting blocks 11.
[0025] Specifically, during operation, the operator must first secure the first base plate 5. This is done by accurately aligning the mounting holes 8 on the four mounting blocks 11 on the bottom side of the first base plate 5 with the installation positions in the elevator pit, thus securing and limiting the first base plate 5. At this point, the first top plate 1 on the top side of the first base plate 5 is positioned corresponding to the bottom of the elevator. When the elevator descends until its bottom contacts the top side of the first top plate 1, the four fixing columns 6 on the bottom side of the first top plate 1 begin to provide support, supporting both the first top plate 1 and the first base plate 5. A damping rod 19 is installed on the top side of the fixing column 6, and the damping rod 19 slides within the groove 20 inside the fixing column 6.
[0026] Reference Figure 4 The top side of the first base plate 5 is fixedly connected to four fixed columns 6. Each of the four fixed columns 6 has a sliding groove 20 on its top side. The top of the sliding groove 20 is slidably connected to a damping rod 19, and the bottom of the sliding groove 20 is provided with a spring 21.
[0027] Specifically, as the elevator continues to descend, the damping rod 19 gradually slides downwards. When the bottom side of the damping rod 19 slides downwards and contacts the spring 21 at the bottom end of the slide groove 20, the spring 21 deforms due to the pressure, thereby generating elastic potential energy. Under the action of the elastic potential energy generated by the spring 21, the pressure on the top side of the damping rod 19 is decomposed, thus preventing damage to the structure of the device due to excessive impact force.
[0028] Reference Figure 3Two mounting brackets 4 are fixedly connected to the left and right sides of the first top plate 1 and the left and right sides of the first bottom plate 5. The mounting brackets 4 are slidably connected to the inside of the mounting brackets 4. Two limiting grooves 18 are opened on the outer wall of the limiting column 14. Rotating shafts 15 are rotatably connected to the front sides of the mounting brackets 4. Limiting plates 16 are fixedly connected to the outer walls of the two rotating shafts 15.
[0029] Specifically, the mounting bracket 4 engages with the slide rails 2 on the two side fixing plates 3. After the mounting bracket 4 moves along the slide rails 2 to the predetermined position, the limiting post 14 is inserted into the slide rail 2 through the limiting holes 17 on both sides of the mounting bracket 4. After the insertion operation is completed, the limiting plates 16 on both sides of the mounting bracket 4 are rotated into the limiting grooves 18 on the outer wall of the limiting post 14, so that they engage with the limiting post 14. In this way, the fixing and limiting operation of the first top plate 1 and the first bottom plate 5 on both sides is completed, ensuring that the entire device is installed stably and reliably in the elevator pit.
[0030] Working principle: The operator first aligns the mounting holes 8 on the four mounting blocks 11 on the bottom side of the first base plate 5 with the installation position in the elevator pit, thus fixing and limiting the first base plate 5. The top side of the first top plate 1 contacts the bottom of the elevator. When the elevator descends to the top side of the first top plate 1 and contacts it, the four fixing columns 6 on the bottom side of the first top plate 1 support the first top plate 1 and the first base plate 5. The damping rod 19 on the top side of the fixing column 6 slides inside the groove 20 opened inside the fixing column 6. When the bottom side of the damping rod 19 slides downward and contacts the bottom end of the groove 20... When the spring 21 is in motion, the elastic potential energy generated by the deformation of the spring 21 will decompose the pressure on the top side of the damping rod 19, preventing the impact force from damaging the device structure. The first top plate 1 and the first bottom plate 5 are engaged with the slide rails 2 on the two fixed plates 3 by the mounting bracket 4. After moving to the predetermined position, the limiting post 14 is inserted into the slide rail 2 through the limiting holes 17 opened on both sides of the mounting bracket 4. After the insertion is completed, the limiting plates 16 on both sides of the mounting bracket 4 are rotated into the limiting grooves 18 opened on the outer wall of the limiting post 14 and engaged with it to complete the fixed limiting.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
