Description

Technical Field

[0001] This utility model relates to the field of vertical shaft construction technology. Specifically, it is a safety protection device for a vertical shaft construction vehicle stabilization system. Background Technology

[0002] As shallow mineral resources are depleted, the development of deep resources is gradually being put on the agenda. As an important facility for resource development, the depth of vertical shafts is also gradually increasing. The synchronous centralized control of the construction suspension platform is a crucial link that directly affects the construction progress and is also an important facility affecting the safe construction of the shaft.

[0003] During shaft excavation, multiple jacking machines are required to operate simultaneously for tasks such as formwork erection and concrete pouring, shaft wall construction, and equipment installation. Jacking machines include slipform jacking machines, platform jacking machines, hook jacking machines, chute jacking machines, pump jacking machines, and cable jacking machines. A typical shaft sinking jacking group consists of two or more jacking machines of the same or different types. Currently, jacking machines are operated manually on-site. Multiple jacking machines are typically operated independently above and below the platform, requiring multiple operators to coordinate. Each operator relies on signal transmission, which cannot guarantee timely and synchronized signal transmission. This results in poor real-time control of the jacking group, easily leading to operational errors and affecting construction progress and safety. Utility Model Content

Detailed Implementation

[0021] This embodiment includes a safety protection device for a vertical shaft construction vehicle stabilization system, such as... Figure 1 As shown, the device includes a frame 1, a main shaft 2, and a rotating wheel 3. The main shaft 2 is rotatably mounted on the frame 1. The rotating wheel 3 is coaxially fixedly mounted on the main shaft 2. An anti-reverse gear 4 is coaxially mounted on the side wall of the rotating wheel 3. An anti-reverse lever 7, which can swing, is mounted on the frame 1. The anti-reverse lever 7 and the anti-reverse gear 4 are matched. A first position sensor 9 is mounted on the frame 1 within the swing range of the anti-reverse lever 7. A braking component 10, connected to the rotating wheel 3, is mounted on the frame 1. The braking component 10 is driven by a connecting device. There is a driving arm 11 for driving the braking component 10 to contact or separate from the rotating wheel 3. A driving drive component 14 is fixedly installed on the frame 1. The power output end of the driving drive component 14 is hinged to the middle of the driving arm 11. A reset counterweight 15 is connected to the end of the driving arm 11 away from the braking component 10. A second position sensor 13 is installed on the frame 1 within the range of motion of the driving arm 11. The first position sensor 9 and the second position sensor 13 are respectively connected to the PLC host through sensor lines.

[0022] like Figure 2 As shown, a fixed base 5 is fixedly installed on the frame 1, and a rotating shaft 6 is rotatably installed on the fixed base 5. The anti-reverse paddle 7 is fixedly installed on one end of the rotating shaft 6. A rotation drive component is also installed on the fixed base 5, and the rotation drive component is connected to the rotating shaft 6 in a transmission manner.

[0023] like Figure 1 As shown, a first mounting plate 8 is fixedly installed on the frame 1, and the first position sensor 9 is fixedly installed on the first mounting plate 8. The detection end of the first position sensor 9 is oriented towards the anti-reverse lever 7. A long groove is formed on the first mounting plate 8 along its length direction, and the end of the first position sensor 9 is fixed in the long groove by bolts.

[0024] like Figure 1As shown, a second mounting plate 12 is installed on the frame 1, and the second position sensor 13 is fixedly installed on the second mounting plate 12. The detection end of the second position sensor 13 is oriented toward the driving arm 11. A long groove is formed on the second mounting plate 12 along its length direction, and the end of the second position sensor 13 is connected to the long groove by bolts.

[0025] like Figure 1 As shown, the anti-reverse paddle 7 is connected to the fixed base 5 via the rotating shaft 6 and is connected to the rotary drive component, which can be a rotary cylinder or an electric motor. When the vehicle is started, the anti-reverse paddle 7 rotates under the drive of the rotary drive component and separates from the anti-reverse gear 4. While the anti-reverse gear 4 swings, it touches the first position sensor 9. After the PLC host obtains the signal from the first position sensor 9, it sends a start signal.

[0026] When the machine stops, the anti-reverse gear 4 swings in the opposite direction, engages with other anti-reverse gears, locks the anti-reverse gear 4, and simultaneously touches the first position sensor 9. After the PLC host obtains the signal, it sends a stop and start signal to realize the automatic anti-reverse function.

[0027] When driving is required, the driving drive component 14 is powered on and operates, causing the driving arm 11 to rise in height, thereby closing the brake. At the same time, the driving arm 11 touches the second position sensor 13, and the PLC host receives the signal and sends a signal indicating that driving is possible. When driving is stopped, the driving drive component 14 is de-powered, and the driving arm 11 automatically falls due to the reset counterweight 15, thereby realizing the automatic braking function. At the same time, it touches the second position sensor 13, and the PLC host receives the signal and sends a stop signal.

[0028] like Figure 3 As shown, the first position sensor 9 and the second position sensor 13, when the vehicle is running, detect that the anti-reverse lever 7 and the braking component 10 are normally closed, and send a normal operation signal to the PLC host. The PLC host then sends the signal to the operator at the vehicle control panel. If the sensors do not detect a signal, the PLC cabinet sends an error signal to the operator, reminding them to stop the vehicle and check for safety hazards. When the vehicle stops, the first position sensor 9 and the second position sensor 13 detect whether the anti-reverse lever 7 and the braking component 10 have reached the correct operating position on the drive arm 11, and feed this information back to the operator via the PLC cabinet, allowing the operator to understand the real-time safety status of the vehicle. This device can reduce manual operation, improve work efficiency, and ensure the safe operation of the vehicle control system.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
