Technical Field

[0001] This utility model relates to the field of protective devices, and in particular to a protective device for the working area of ​​a rotary drilling rig. Background Technology

[0002] Rotary drilling rigs are construction machines suitable for hole-forming operations in building foundation engineering. They are mainly suitable for construction in soil layers such as sand, cohesive soil, and silty soil. They are widely used in various foundation constructions such as cast-in-place piles, continuous walls, and foundation reinforcement. When rotary drilling rigs are in operation, due to their large size and the often complex and changeable working environment, there are significant safety hazards. Therefore, protective devices are usually installed to protect their working area. The protective devices for the working area of ​​rotary drilling rigs are mainly used to ensure the safety and efficiency of the construction process. They are an important measure to ensure the smooth progress of the construction process and protect the safety of personnel and equipment.

[0003] Existing rotary drilling rig working area protection devices typically employ a fixed structure, making it difficult to flexibly adjust according to changes in the construction site. This limits their applicability and they lack intelligent functions, failing to monitor the construction site in real time or automatically trigger warnings when personnel or objects approach, thus posing significant safety hazards.

[0004] Therefore, in view of the problems that existing rotary drilling rig work area protection devices are generally inflexible, unable to respond in a timely manner, and pose significant safety hazards, a rotary drilling rig work area protection device can be designed, consisting of multiple sets of modular fence components. The number of fence components can be flexibly increased or decreased according to the size of different work areas. By setting monitoring components on the fence components, monitoring data can be transmitted to a remote terminal in real time, and warnings can be issued when abnormalities occur.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] A rotary drilling rig is a type of piling machinery used for foundation engineering construction. It mainly consists of a chassis, mast, power head, drill rod, and drill bit. During operation, the power head drives the drill rod and drill bit to rotate, using the cutting edge on the drill bit to break the rock and soil. At the same time, the rig's pressurization device applies downward pressure to the drill rod, enabling the drill bit to effectively cut into the strata. During the drilling process, the winch controls the raising and lowering of the drill rod, lifting the broken rock and soil to the ground to form a pile hole.

[0022] During the operation of rotary drilling rigs, due to their large size and complex working environment, their working areas often pose significant safety hazards. To ensure safety at the construction site, protective devices are typically installed in the working area of ​​rotary drilling rigs. Their main functions are as follows:

[0023] Protect the lives of personnel

[0024] When a rotary drilling rig is working, its drill rod undergoes complex movements such as high-speed rotation and up-and-down movement. Without protective devices, on-site construction workers may inadvertently approach the rig. Contact with the rotating drill rod or being struck by falling debris can result in serious personal injury, such as limb entanglement or fractures. Installing protective devices effectively isolates dangerous areas and prevents construction workers from entering hazardous zones.

[0025] Rotary drilling rigs generate high levels of noise during operation, and prolonged exposure to such an environment can damage hearing. Furthermore, the drilling process produces a large amount of dust, which, if inhaled, can harm respiratory health. Soundproof enclosures and dustproof facilities in the work area can significantly reduce the harm caused by noise and dust to construction workers.

[0026] Protect the safety of the equipment itself

[0027] On construction sites, the environment is complex, and other vehicles, equipment, or objects may accidentally approach the rotary drilling rig. In the event of a collision, critical components of the rig, such as the engine, hydraulic system, and drill rod, may be damaged. Setting up protective structures such as crash barriers and buffer devices can absorb and disperse the impact force in the event of a collision, reducing the risk of equipment damage.

[0028] Rotary drilling rigs are high-precision mechanical devices, and their operational stability is crucial to their lifespan and performance. If the ground in the working area is not firm enough or there is no proper protection, the drilling rig may be damaged due to ground subsidence, tilting, or other issues. Ground reinforcement and drainage facilities in the protective device can effectively prevent these problems and extend the service life of the equipment.

[0029] Ensure construction accuracy

[0030] During the drilling process, rotary drilling rigs need to maintain a stable working state to ensure the verticality and accuracy of the borehole. For example, in strong winds, without wind protection facilities, the drill rod may shift, causing the borehole to tilt and affecting the subsequent construction quality. The bearing capacity of the pile foundation and the protection device of the working area can provide a relatively stable working environment for the drilling rig to ensure that the construction quality meets the requirements.

[0031] When foreign objects (such as branches, stones, and garbage) enter the working area of ​​the drilling rig and get caught in its moving parts, it may cause the drill rod to vibrate more or the equipment to malfunction, thus affecting the quality of drilling. Setting up protective nets and other devices can effectively prevent foreign objects from entering and ensure the accuracy of construction.

[0032] Improve construction efficiency

[0033] If rotary drilling rigs frequently stop working due to equipment damage, malfunctions, or external interference, it will seriously affect the construction progress. Work area protection devices can reduce the impact of these adverse factors, enabling the drilling rig to work continuously and stably. For example, by preventing collisions and foreign object interference, they can reduce the equipment failure rate, reduce maintenance time, and thus improve construction efficiency.

[0034] A stable working environment also allows operators to focus more on construction operations without worrying about potential dangers, thereby improving work efficiency. For example, in a quiet and clean working environment, operators can better observe the working status of the drilling rig, adjust parameters in a timely manner, and ensure the smooth progress of the construction process.

[0035] Currently, various types of protective devices for rotary drilling rig work areas are available on the market, designed to comprehensively ensure the safety of operators and equipment or prevent nearby residents and vehicles from accidentally entering. For example: 1. Protective fences: Typically made of metal or high-strength plastic, these fences surround the rotary drilling rig's work area, isolating it from the outside world and preventing unauthorized entry by personnel and vehicles. Some fences also include locks and warning signs to further enhance protection. Disadvantages: Installation and dismantling are relatively complicated, requiring time and manpower. For large rotary drilling rigs, a large amount of fence material may be needed, resulting in higher costs. The fence may also obstruct the operator's field of vision within the work area, and frequent entry and exit may be inconvenient. 2. Crash barriers: These are generally installed around the rotary drilling rig, especially in areas prone to collisions, such as the sides of the rig and the base of the mast. When an object impacts the crash barrier, the barrier absorbs and disperses the impact force through structural deformation or cushioning materials, thus protecting critical components of the drilling rig from damage. Disadvantages: The crash barriers may be damaged under significant impact, requiring timely replacement or repair. Some crash barrier designs may increase the overall width of the drilling rig, potentially affecting its movement and operation in narrow construction sites. 3. Light Curtain Sensor: Composed of a projector and a receiver, the projector emits modulated infrared light, which is received by the receiver, forming a protective net. When an object enters the net, blocking the light, the receiver circuit reacts immediately by outputting a signal. Upon receiving the signal, the rotary drilling rig's control system immediately stops operation or takes other safety measures, such as braking or alarms. Disadvantages: Strong light interference or factors affecting light propagation, such as dust or fog, may cause the light curtain sensor to misjudge or malfunction. The protection range of the light curtain sensor is limited. For large rotary drilling rigs or large working areas, multiple light curtain sensors may need to be used in combination, increasing cost and installation difficulty. 4. Soundproof Enclosure: Generally made of sound-absorbing materials such as sound-absorbing cotton and sound-insulating panels, this enclosure contains the main noise sources of the rotary drilling rig, such as the power head and drill rod, reducing noise transmission. The outer shell of the soundproof enclosure is usually sandwiched, with a hollow interior. It absorbs and reflects sound waves through multiple layers of sound insulation structure and sound-absorbing materials, thereby reducing noise pollution at the construction site. Disadvantages: The soundproof enclosure increases the overall size and weight of the drilling rig, potentially affecting its movement and operational flexibility. The sound insulation materials may age and damage after long-term use, requiring regular replacement and increasing maintenance costs.

[0036] Although there are various types of protective devices for the working area of ​​rotary drilling rigs on the market, each with different working methods and disadvantages, in practical applications, the appropriate protective device should be selected according to the specific construction needs and equipment model, and regular maintenance and inspection should be carried out to ensure its effectiveness.

[0037] Please see Figure 1 This utility model provides an embodiment of a protective device for the working area of ​​a rotary drilling rig, including a fence assembly and a monitoring assembly. Multiple sets of fence assemblies are evenly distributed around the working area of ​​the rotary drilling rig. Each set of fence assemblies has two sets of monitoring assemblies detachably installed at the upper middle part, which are symmetrically arranged to monitor the working area of ​​the rotary drilling rig and the outside, and to provide warnings when unauthorized personnel or vehicles enter.

[0038] Please see Figures 2-3 In this embodiment, the fence assembly includes a fence 101, a base 102, a protrusion 103, posts 104, a handle 105, a locking block 106, a locking sleeve 107, and a warning sign 108. The lower end of the fence 101 is fixedly connected to the base 102. Three sets of posts 104 are evenly distributed from left to right on both sides of the base 101. The posts 104 extend from the upper end of the base 102 to the lower end. A handle 105 is fixedly connected to the upper end of each post 104. Two sets of locking blocks 106 are fixedly installed symmetrically on the right end. Two sets of retaining sleeves 107 are fixedly installed on the right end of the enclosure 101 at the position corresponding to the locking blocks 106. The two adjacent sets of enclosures 101 are interlocked by the locking blocks 106 and retaining sleeves 107. Two sets of threaded holes 109 are symmetrically opened in the middle of the upper end of the enclosure 101. A warning sign 108 for warning and reminder is provided in the middle of the upper outer side of the enclosure 101. The four corners of the warning sign 108 are detachably connected to the enclosure 101 by bolts.

[0039] Please see Figure 4In this embodiment, the monitoring component includes a mounting block 201, a threaded post 202, a first connecting block 203, a second connecting block 204, a third connecting block 205, a drive motor 206, an infrared sensor 207, an alarm 208, and a camera 209. The lower end of the mounting block 201 is fixedly connected to the threaded post 202, and the mounting block 201 is detachably connected to the fence component via the threaded post 202. The upper end of the mounting block 201 is fixedly connected to the first connecting block 203, and the first connecting block 203 and the third connecting block 205 are rotatably connected via the second connecting block 204. Drive motors 206 are provided on the outer sides of the connection points between the first connecting block 203, the second connecting block 204, and the third connecting block 205. The machine 206 is equipped with an output shaft. The output shafts of the two sets of drive motors 206 extend from the outside of the first connecting block 203 and the second connecting block 204 to the inside, respectively, to drive the second connecting block 204 and the third connecting block 205 to rotate. A camera 209 is fixedly connected to the end of the third connecting block 205 away from the drive motor 206. An infrared sensor 207 is fixedly installed at the lower end of the camera 209, and an alarm 208 is fixedly installed at the upper end of the camera 209. Both the infrared sensor 207 and the alarm 208 are electrically connected to the camera 209. The alarm 208 consists of a speaker and a warning light. The camera 209 is equipped with a network communication module, a control module, an intelligent processing module, and a power management module.

[0040] When carrying out the work, first prepare the corresponding number of fence components and double the number of monitoring components according to the actual size of the working area of ​​the rotary drilling rig;

[0041] Then, the monitoring component is installed and fixed on the upper end of the fence component enclosure 101. The monitoring component is installed and fixed in the threaded hole 109 at the upper end of the enclosure 101 through the threaded post 202 at the lower end of the monitoring component mounting plate, and the orientation of the two sets of monitoring components on the enclosure 101 is one inward and one outward.

[0042] Next, install and fix the fence components in the corresponding area, and snap the two adjacent sets of fences 101 in the same row together using the clip 106 and the clip 107.

[0043] Then, the base 102 is fixed by the insertion post 104 on the base 102. The handle 105 at the upper end of the insertion post 104 is turned to control the insertion post 104 to move downward until the insertion post 104 is firmly inserted into the ground, so that the base 102 provides stable support for the enclosure 101.

[0044] Next, the warning sign 108 with relevant warning words is installed and fixed on the outside of the fence 101;

[0045] Repeat the above steps until all the fence components are installed, thus enclosing the working area of ​​the rotary drilling rig.

[0046] During the operation of the fence and monitoring components, the monitoring component monitors and senses the surrounding environment in real time, captures video through camera 209, and senses people and vehicles in the vicinity through infrared sensor 207. When infrared sensor 207 detects a person or vehicle accidentally entering, it will trigger alarm 208 to flash warning and provide voice alarm reminder. The monitoring component will transmit relevant monitoring video data to the remote terminal in real time, thereby enabling the archiving of monitoring information, which is convenient for staff to investigate the situation or promptly arrive at the scene to handle any abnormalities.

[0047] Through the above steps, the modular fence components facilitate installation and disassembly. The number of fence components can be flexibly increased or decreased according to the size of different work areas, improving the adaptability and flexibility of the device. By installing monitoring components on the fence components to monitor and issue warnings, monitoring data can be transmitted to a remote terminal in real time, and warnings can be issued in case of abnormalities. This effectively prevents accidents and protects the personal safety of construction personnel. This addresses the problems of existing rotary drilling rig work area protection devices, which typically use fixed structures, making it difficult to flexibly adjust to changes in the construction site, limiting their applicability, and lacking intelligent functions. They cannot monitor the construction site in real time, nor can they automatically trigger warnings when personnel or objects approach, posing significant safety hazards.
