[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1 As shown, this utility model provides a construction device for an elevator shaft, including a base 1. A guardrail 4 is fixedly connected to the upper side of the base 1. Two directional wheels 5 are fixedly connected to the upper side of the guardrail 4. A steel rope 6 is movably connected to the inner surface of the directional wheels 5. Multiple tracks 2 are provided on the outer wall of the base 1. A groove 7 is opened on the side of the track 2 near the base 1. A locking plate 3 is fixedly connected to the opposite side of the two tracks 2. The base 1 serves as the basic load-bearing component of the entire construction device. The guardrail 4 is used to ensure the safety of construction personnel on the device and prevent accidental falls. The cooperation between the directional wheels 5 and the steel rope 6 allows the construction device to move up or down via the steel rope 6. The tension of the steel rope 6 acts on the directional wheels 5, which guide the direction of the steel rope 6 and ensure the stability of the device's movement. The tracks 2 are installed in the elevator shaft to provide guidance and positioning for the construction device. The groove 7 cooperates with the roller assembly 8 to allow the device to move up and down along the track 2. The locking plate 3 cooperates with the locking component of the device to lock it to the track 2 in case of abnormal conditions.

[0025] like Figures 2-3As shown, this utility model provides a technical solution: Preferably, movable columns 10 are slidably connected to both the left and right sides of the base 1. Rotating plates 12 are rotatably connected to both the front and rear sides of the movable columns 10. A moving column 11 is rotatably connected to the other end of the rotating plate 12. A locking block 13 is fixedly connected to the side of the moving column 11 away from the movable column 10. Two limiting sleeves 9 are fixedly connected to both the left and right sides of the base 1. Two roller assemblies 8 are fixedly connected to both the left and right sides of the base 1. The outer wall of the roller assembly 8 is movably connected to the sliding groove 7. The outer wall of the moving column 11 is slidably connected to the limiting sleeve 9. The outer wall of the locking block 13 is movably connected to the locking plate 3. A cylinder 15 is fixedly connected to the front side of the inner wall of the base 1. A support plate 17 is fixedly connected to the output end of the cylinder 15. A movable block 16 is fixedly connected to the lower side of the support plate 17. Two inclined grooves 18 are opened on the upper side of the movable block 16. A guide column 14 is slidably connected to the inner surface of the inclined groove 18. The outer wall of the guide column 14 is connected to the movable column 10. The movable block 16 is fixedly connected to the outer wall of the base 1 and slidably connected to the base 1. When the device is running normally, the roller assembly 8 rolls in the slide groove 7 and the device moves up and down along the track 2. When the device falls, in order to achieve quick locking, the cylinder 15 is activated. The output end of the cylinder 15 pushes the support plate 17 to move. The support plate 17 drives the movable block 16 to slide in the base 1. Since the movable block 16 has a sloping groove 18 and the sloping groove 18 is slidably connected to the guide post 14, and the guide post 14 is fixedly connected to the movable post 10, the sliding of the movable block 16 will cause the guide post 14 to move along the sloping groove 18, thereby driving the movable post 10 to move outward. The movement of the movable post 10 drives the movable post 11 to slide in the limit sleeve 9 through the rotating plate 12, and finally causes the locking block 13 to move outward and lock with the locking plate 3, forcibly fixing the device on the track 2 to avoid catastrophic accidents caused by uncontrolled falling. This locking structure can be triggered quickly to ensure the safety of the device.

[0026] like Figures 4-5As shown, this utility model provides a technical solution: Preferably, a base plate 20 is provided below the base 1, an air cushion 21 is fixedly connected to the lower side of the base plate 20, and multiple telescopic columns 22 are fixedly connected to the upper side of the base plate 20. The upper end of the telescopic columns 22 is fixedly connected to the base 1, and a first spring 23 is sleeved on the outer wall of the telescopic column 22. One end of the first spring 23 is fixedly connected to the base plate 20, and the other end of the first spring 23 is fixedly connected to the base 1. Two rotating plates 24 are rotatably connected to the upper side of the base plate 20, and a slider 26 is rotatably connected to the other end of the rotating plates 24. Two pairs of connecting plates 19 are fixedly connected to the lower side of the base 1, and a limiting post 25 is fixedly connected to the opposite face of the two connecting plates 19. The outer wall of the limiting post 25 is slidably connected to the slider 26, and the upper side of the slider 26 is slidably connected to the base 1. Two second springs 27 are sleeved on the outer wall of the limiting post 25, and one end of the second spring 27 is fixedly connected to the connecting plate 19. The other end is fixedly connected to the slider 26. When the construction device descends and contacts the bottom structure or a falling object hits the base 1, the buffer structure at the bottom of the device begins to function. First, the air cushion 21 can play a certain buffering role by absorbing part of the impact force through gas compression. At the same time, the telescopic column 22 will be compressed, and the first spring 23 will also be compressed. The elastic deformation of the first spring 23 can absorb a large amount of energy and slow down the descent speed of the device. In addition, the structure composed of the rotating plate 24, slider 26, limiting column 25 and second spring 27 also plays a buffering role. When the base 1 is subjected to impact force and moves downward, the slider 26 slides on the limiting column 25, the rotating plate 24 rotates, and the second spring 27 is compressed. The elastic force of the second spring 27 further absorbs the impact force. The buffer device can effectively absorb the impact force of the construction device or falling object, reduce the direct impact on the bottom structure or ground, and protect the bottom structure of the well and ground facilities.

[0027] The working principle of the elevator shaft construction device for this building will be explained in detail below.

[0028] like Figures 1-5As shown, when the device is operating normally, the roller assembly 8 rolls in the slide groove 7, and the device moves up and down along the track 2. When the device falls, in order to achieve rapid locking, the cylinder 15 is activated. The output end of the cylinder 15 pushes the support plate 17 to move. The support plate 17 drives the movable block 16 to slide in the base 1. Since the movable block 16 has a sloping groove 18, and the sloping groove 18 is slidably connected to the guide post 14, and the guide post 14 is fixedly connected to the movable post 10, the sliding of the movable block 16 will cause the guide post 14 to move along the sloping groove 18, thereby driving the movable post 10 to move outward. The movement of the movable post 10 drives the movable post 11 to slide in the limit sleeve 9 through the rotating plate 12, and finally causes the locking block 13 to move outward and lock with the locking plate 3, forcibly fixing the device on the track 2, avoiding catastrophic accidents caused by uncontrolled falling. This locking structure can be triggered quickly to ensure the safety of the device. When the construction device descends and contacts the bottom structure or when a falling object impacts the base 1, the buffer structure at the bottom of the device begins to function. First, the air cushion 21 provides some cushioning by absorbing some of the impact force through gas compression. Simultaneously, the telescopic column 22 is compressed, and the first spring 23 is also compressed. The elastic deformation of the first spring 23 can absorb a large amount of energy, slowing down the descent speed of the device. In addition, the structure composed of the rotating plate 24, the slider 26, the limiting column 25, and the second spring 27 also provides cushioning. When the base 1 is impacted and moves downward, the slider 26 slides on the limiting column 25, the rotating plate 24 rotates, and the second spring 27 is compressed. The elastic force of the second spring 27 further absorbs the impact force. The buffer device can effectively absorb the impact force of the construction device or falling object, reduce the direct impact on the bottom structure or the ground, and protect the bottom structure of the shaft and the ground facilities.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
