Description

Technical Field

[0001] The present invention relates to the field of material transportation for deep shafts and ultra-deep shaft structure construction in underground engineering, and in particular to a recyclable and reusable assembled shaft material transportation escape passage device and method. Background Art

[0002] Conventional shaft material transportation involves lifting equipment and its ropes, slings, containers, rails, ground anchors, etc. and various safety devices. The construction steps are cumbersome, the on-site labor cost is high, the material transportation cycle is long, and there are construction risks such as horizontal shaking or even rollover of the container and rope breakage during the vertical lifting of construction materials by ropes. The safety risks of personnel and equipment at the bottom of the shaft are high, and there is no effective escape route for construction personnel at the bottom. In addition, the ropes, slings, containers, rails, ground anchors, etc. cannot be recycled and reused, resulting in a lot of material waste, which is not in line with the national green and low-carbon construction policy.

[0003] Disadvantages of existing technology: Existing deep shaft and ultra-deep shaft material transportation includes lifting equipment and its ropes, slings, containers, rails, ground anchors, etc. and various safety devices. The construction steps are cumbersome, the on-site labor cost is high, the material transportation cycle is long, and there are construction risks such as horizontal shaking or even rollover of the container and rope breakage during the vertical lifting of construction materials by ropes. The safety risks of personnel and equipment at the bottom of the shaft are high, there is no effective escape route for construction personnel at the bottom, and the ropes, slings, containers, rails, ground anchors, etc. cannot be recycled and reused, resulting in a lot of material waste, which is not in line with the national green and low-carbon construction policy.

[0004] In general: The dilemma of existing conventional shaft material transportation: Equipment and process complexity: Conventional shaft material transportation systems involve many components, including lifting equipment, supporting ropes, slings, containers, rails, anchors, etc., and are also equipped with various safety devices. The installation, commissioning and operation of these equipment need to follow strict and tedious construction steps. Every link requires professional personnel to handle it meticulously, from the connection and fixation of ropes to the precise commissioning of safety devices, no carelessness is allowed. This not only increases the difficulty of construction, but also greatly increases on-site labor costs. The construction team needs to invest a lot of manpower to complete the work in each link, and the professional skills requirements of the personnel are high, which further increases the labor cost.

[0005] Transportation efficiency and cycle time: Long material transportation cycles are a major drawback of conventional shaft material transportation. Due to the complex construction steps, each material transport requires multiple steps of preparation and operation, from material loading, starting the lifting equipment, to material unloading, and the entire process is time-consuming. This seriously impacts the progress of shaft construction, prolongs the overall construction period, and increases the project's time cost.

[0006] Safety risks: There are many safety risks in the process of vertically lifting construction materials with ropes. The container may sway horizontally or even tip over, which will not only damage the materials but also pose a serious threat to the personnel and equipment in the shaft. Rope breakage is an extremely dangerous situation. Once it happens, the materials will fall directly, which may cause a serious safety accident and endanger the lives of people at the bottom of the shaft and the normal operation of the equipment. In addition, there is a lack of effective escape routes for construction workers at the bottom of the shaft. In the event of an emergency, it is difficult for people at the bottom to evacuate quickly, greatly increasing the risk of casualties.

[0007] Resource waste is inconsistent with policy: Equipment such as ropes, spreaders, containers, rails, and anchors cannot be recycled after use. New equipment must be used for each construction project, resulting in significant material waste. Given the national policy of promoting green and low-carbon construction, this high-consumption, high-waste construction method is clearly inconsistent with policy guidelines and detrimental to sustainable development.

The signal guide rail 13 is a signal transmission guide rail of the intelligent transport vehicle. The signal guide rail 13 is installed on the I-beam 6 by being combined with insulating rubber.

[0018] A further technical solution of the present invention is: The round steel support and steel shell provide support for the I-beam and form an escape route, which is an important part of the escape route for workers at the bottom of deep shafts and ultra-deep shafts; Angle steel support is a fixing device that connects the standard section to the outer wall of the deep shaft, and is specifically connected using bolts and slides; The steel shell provides protection for the internal structure and prevents falling objects caused by materials falling during transportation; The rotating part of the bottom rotating body 1 is automatically recognized and remotely controlled by signals, and the intelligent transport vehicle can change the transport direction by adjustment. The I-beam of the bottom rotating body 1 and the corresponding straight teeth 5 include two groups; The straight teeth, I-beams, angle steel supports, convex guide rails, power guide rails, insulating rubber, signal guide rails, and insulating rubber parts of the bottom rotating body are only different in length from the standard section, and the rest of the specifications are exactly the same; The stepper motor controller has the function of automatic signal recognition and has two control modes: automatic and remote. The standard section is the key equipment part that continuously extends the overall equipment.

[0019] A further technical solution of the present invention is that the rotating wheel is a walking device of the rotating part, which moves on the rotating slide rail and has a supporting function; The round steel support frame connects the rotating wheel and the I-beam to provide skeleton support for the rotating part; The rotating slide rail is welded to the steel shell of the bottom rotating body. It is the moving track of the rotating wheel and provides support for it. It has high strength bearing capacity. The steel shell of the bottom rotating body provides protection for the internal structure and also absorbs falling objects caused by materials falling during transportation. Its side walls have material inlets and outlets for loading slag and concrete in the shaft. The rotating slide is welded to the steel shell of the bottom rotating body, has teeth, and meshes with the gears of the stepper motor. It has a certain load-bearing capacity, but does not carry loads. The top unloading device is a device that changes the direction of the track to unload, flush, and redirect the intelligent transport vehicle. The sensor controls the signal transmitted to the intelligent transport vehicle to achieve the purpose of unloading, flushing, and redirecting the intelligent transport vehicle. The straight teeth, I-beams, angle steel supports, convex slide rails, power guide rails, insulating rubber, signal guide rails, and insulating rubber parts of the top unloading device are only different in length from the standard section, and the rest of the specifications are exactly the same; The arc-shaped I-beam, arc-shaped rack, convex slide rail (arc-shaped, arc-shaped power guide rail, arc-shaped signal guide rail) of the top unloading device are made by bending the corresponding rails and supports of the standard section.

[0020] The steel shell provides protection for the internal structure, preventing falling objects caused by materials during transportation, while forming a material receiving chute to facilitate the collection and processing of debris; Round steel supports and steel shells provide support for the curved I-beams; The steering shaft is connected to the reducer, connected to the fixed steel plate through bearings, and welded to the connecting steel plate.

The control process is as follows: after the unloading device detects that the transport vehicle has entered and the transport vehicle has stopped running in the rotating body, the flushing device starts the flushing work. After the flushing work is completed, the unloading device rotating body rotates. After the rotation is completed, the rotation completion signal is output to the system.

It completes the scheduled cleaning work through system signals. Specifically, it receives the system start signal, runs a flushing process, and then stops automatically.

[0021] A further technical solution of the present invention is that the intelligent transport vehicle is the main carrier for material transportation. The stepper motor controller, power and signal transmission device constitute the intelligent control system of the intelligent transport vehicle. The sensor receives signals, and the controller receives external signals for intelligent operation. The worm gear mechanism enables the intelligent transport vehicle to lock its position and stop operation when the stepper motor fails or the power goes out, thereby achieving the purpose of intelligent and safe operation of the intelligent transport vehicle. The reducer is coupled to the stepper motor via helical gears, providing high torque and appropriate speed for the intelligent transport vehicle. The reduction mechanism is a worm gear mechanism, with a worm at the power input end and a turbine at the output end. When the stepper motor stops working, the internal worm gear mechanism self-locks. The method for recyclable and reusable prefabricated shaft material transport escape passage is characterized by utilizing any of the above-described recyclable and reusable prefabricated shaft material transport escape passage devices. Its operation and control principles are as follows: A. When the transport vehicle reaches the bottom rotating body, the contact switch receives a signal and stops running. The rotating body rotates, changing the direction of the transport vehicle. After the transport vehicle is loaded, a rotation confirmation signal is sent. While maintaining the contact switch signal, the transport vehicle receives the rotation confirmation signal and starts running in the opposite direction until it receives the contact switch signal again. B. When the transport vehicle reaches the top unloading device, the contact switch stops running upon receiving the signal. After the flushing device is completed, the rotating body rotates to change the direction of the transport vehicle. After the rotation of the transport vehicle is completed, a rotation confirmation signal is sent. While maintaining the contact switch signal, the transport vehicle starts running in the opposite direction upon receiving the rotation confirmation signal until it receives the contact switch signal again. C. When the transport vehicle enters the unloading device, and there is a transport vehicle in the unloading device that has not completed its rotation, the unloading device stops running; D. When the transport vehicle enters the unloading device and there is no transport vehicle in the unloading device, it operates normally; E. The transport vehicle distance detection device stops running when it detects that the distance between the transport vehicle and the previous transport vehicle is less than the set distance in the running direction. It runs normally when the distance is greater than the set distance.

[0022] The present invention, employing the above-mentioned technical solution, has the following advantages over existing technologies: The application of this intelligent, recyclable, and reusable prefabricated material rapid transport equipment significantly improves the safety of workers and equipment at the bottom of the shaft. This equipment utilizes advanced intelligent control technology and a stable structural design, effectively reducing the risk of container sway and rollover, and lowering the likelihood of rope breakage. Furthermore, the equipment is equipped with comprehensive safety devices and an emergency response system, enabling timely action in the event of emergencies to ensure the safety of both personnel and equipment.

[0023] This new equipment significantly improves the efficiency of transporting excavated soil and other materials at the bottom of the shaft. It utilizes a rapid loading and unloading system and an intelligent dispatching system, reducing preparation time and operational steps during material transportation and enabling rapid material transport. This not only shortens the material transportation cycle but also accelerates the progress of shaft construction, improving overall efficiency.

[0024] A key advantage of this equipment is the provision of an emergency escape route for personnel at the bottom. The equipment design fully considers personnel safety needs, with dedicated escape routes incorporated. In the event of an emergency, personnel at the bottom can quickly evacuate to a safe area through these escape routes, significantly increasing their chances of survival.

[0025] The recyclable and reusable nature of the equipment reduces material waste and lowers equipment rental costs. After each construction phase, the equipment's major components can be recycled, reassembled, and reused, saving significant costs. Furthermore, this green, low-carbon construction method aligns with national policies and guidelines, contributing to green, low-carbon, and safe material transportation in deep and ultra-deep shafts, thereby improving the overall efficiency of deep and ultra-deep shaft construction.

[0026] To sum up, the application of intelligent rapid transportation equipment for recyclable and reusable assembled materials is an effective way to solve the problem of conventional shaft material transportation, and has significant economic and social benefits.

After the flushing process is completed, the unloading device's rotating body rotates. After the rotation is completed, the rotation completion signal is output to the system. The control code structure is as follows: #include<Stepper.h> / / Define the number of steps of the stepper motor const int stepsPerRevolution = 200; / / Stepper motor control pin int stepPin = 8; int dirPin = 9; / / Contact switch pin int contactSwitchPin = 2; / / Flushing device control pin int washPin = 3; / / Rotation confirmation signal pin int rotationConfirmPin = 13; / / Create a stepper motor object Stepper myStepper(stepsPerRevolution, stepPin, dirPin); / / Define state variables bool transportInRotator = false; bool washComplete = false; bool rotationComplete = false; void setup() { / / Initialize serial communication Serial.begin(9600); / / Set the stepper motor pin to output mode pinMode(stepPin, OUTPUT); pinMode(dirPin, OUTPUT); / / Set the contact switch pin to input mode pinMode(contactSwitchPin, INPUT); / / Set the flushing device control pin to output mode pinMode washPin, OUTPUT); / / Set the rotation confirmation signal pin to output mode pinMode(rotationConfirmPin, OUTPUT);} void loop() { int contactSwitchState = digitalRead(contactSwitchPin); / / Detect that the transport vehicle enters and stops running in the rotating body if (contactSwitchState == HIGH&&!transportInRotator) { transportInRotator = true; Serial.println("The transport vehicle has entered the rotating body"); / / Start the flushing device digitalWrite(washPin, HIGH); / / Wait for flushing to complete delay(2000); washComplete = true; digitalWrite(washPin, LOW); Serial.println("Flushing completed"); } / / Rotate after flushing is complete if (washComplete&&!rotationComplete) { / / Control the rotation of the rotating body rotateRotator(360); rotationComplete = true; digitalWrite(rotationConfirmPin, HIGH); Serial.println("Rotation completed"); } if (rotationComplete) { / / Other operations after receiving the rotation completion signal Serial.println("Waiting for the next system instruction"); }} void rotateRotator(int degrees) { int steps = (degrees * stepsPerRevolution) / 360; / / Set the rotation direction digitalWrite(dirPin, HIGH); for (int i = 0; i <steps; i++) { myStepper.step(1); / / Set the rotation speed delay(10); } } ⑨The steel structure is the fixing and supporting structure of the top unloading device on the ground; ⑩The fixed steel plate is welded in the middle of the arc-shaped I-beam. The middle position has a bearing seat and bearing to provide the axis alignment and certain support for the steering shaft. ⑪ The connecting steel plate is the connecting steel plate of the rotating part I-beam, which is welded to the steering shaft 31; ⑫ The high-pressure water spray device is a high-pressure washing device for intelligent transport vehicles. It completes the scheduled cleaning work through system signals. Specifically, after receiving the system start signal, it runs a washing process and then stops automatically. The control is relatively simple, and its control code framework is not described here. 7) The intelligent transport vehicle is the main carrier for material transportation. It is composed of a reducer, a stepper motor, a stepper motor controller, casters, gears, a power shaft, a driven shaft, a power and signal transmission device, a casing, a motor compartment, and a support. The stepper motor controller, the power and signal transmission device constitute the intelligent control system of the intelligent transport vehicle. It operates intelligently by receiving signals through sensors and the controller receiving external signals. The worm gear mechanism enables the intelligent transport vehicle to lock its position and stop running when the stepper motor fails or the power is off, thereby achieving the purpose of intelligent and safe operation of the intelligent transport vehicle.

[0037] ①The reducer is coupled to the stepper motor through helical gears to provide high torque power and appropriate speed for the intelligent transport vehicle. The reduction mechanism is a worm gear mechanism, with a worm at the power input end and a turbine at the output end. When the stepper motor stops working, the internal worm gear mechanism is self-locking; ②The stepper motor is arranged in the motor compartment and coupled with the reducer through helical gears. Two stepper motors are set up, one for use and one for backup, arranged opposite each other and controlled by an intelligent control system. Its operation and control principles are as follows: A. When the transport vehicle reaches the bottom rotating body, the contact switch stops when it receives a signal. The rotating body rotates, changing the direction of the transport vehicle. After the transport vehicle is loaded, a rotation confirmation signal is sent. While maintaining the contact switch signal, the transport vehicle starts to run in the opposite direction after receiving the rotation confirmation signal until it receives the contact switch signal again.

[0038] B. When the transport vehicle reaches the top unloading device, the contact switch stops running upon receiving the signal. After the flushing device is completed, the rotating body rotates to change the direction of the transport vehicle. After the rotation of the transport vehicle is completed, a rotation confirmation signal is sent. While maintaining the contact switch signal, the transport vehicle starts running in the opposite direction after receiving the rotation confirmation signal until it receives the contact switch signal again.

[0039] C. When the transport vehicle enters the unloading device and there is an unfinished rotation of the transport vehicle inside the unloading device, the device stops running.

[0040] D. When the transport vehicle enters the unloading device and there is no transport vehicle in the unloading device, it operates normally.

[0041] E. The transport vehicle distance detection device stops running when it detects that the distance between the transport vehicle and the previous transport vehicle is less than the set distance in the running direction. It runs normally when the distance is greater than the set distance.
