【Msensor Sensor】DMI2700 rotary drilling rig verticality tilt detection instrument

Real-time monitoring of the verticality deviation of the drill rod during the construction process of rotary drilling and pouring piles, with timely early warning, correction, and detection system.

ZB-HMI2000 Wireless Tilt Detection for Tower Crane Vertical Inclination Offset

Modules can be added according to the number of tower cranes, and the modules can be named (e.g., 1# Tower Crane, 2# Tower Crane, 3# Tower Crane, etc.). A report generation function can be set up, including content such as tower crane number, tower crane height, and the deviation values of verticality on the X and Y axes (distinguishing between positive and negative directions).

The inclination sensor is used for safe operation in coal washing and mining machinery.

By installing an LVG726T dynamic tilt sensor to measure the tilt angle of the chassis in all directions, the angle output signal is sent to the PLC to drive the hydraulic cylinder, thereby achieving the leveling of the chassis.

The MK926 accelerometer is used for monitoring and analyzing the compaction of rollers.

MK926 uses the vibration frequency and amplitude of the accelerometer to monitor in real-time the rolling construction speed, velocity, and excitation force of the roller, checking whether the vibration meets the requirements and whether the vibration conforms to the design specifications. It can also calculate the current excitation force of the roller based on amplitude and vibration frequency.

Dual-axis tilt angle sensor for measuring and controlling the verticality of the mast of rotary drilling rigs and pile drivers.

The verticality of the mast determines whether the drilled hole is qualified, especially for pile drivers, where verticality is an important indicator of the reliability of the building. Therefore, maintaining good verticality or drilling at a certain angle is a common issue encountered during construction. In the electric-hydraulic control system, a dual-axis tilt sensor can be directly installed on the mast to achieve this function. At the same time, operators can input tilt data through the PLC human-machine interface device, and the drilling machine will automatically drill at the set angle. Recommended configuration: (1) Dual-axis tilt sensor + tilt display instrument. Choose the HMI-336T dual-axis digital tilt sensor to monitor the current angle value in real-time. This is a dual-axis measuring horizontal sensor, paired with the DMI2500 tilt display instrument, which allows for an intuitive display of the vertical angle value on the screen. Figure 1.1 HMI-336T rotary drilling rig and pile driver mast verticality measurement and control system. This solution is the simplest and most cost-effective, and our company has provided this configuration to many enterprises. The instrument can be placed in the cab, can be hole-mounted, or directly fixed in a convenient position. The sensor is installed on the mast and connected to the instrument via a dedicated connection cable. Just connect the instrument to a 24V DC power supply. Connection cables are available in specifications of 2m, 5m, 10m, 12m, 15m, etc. Function description: 1. Absolute angle display (default screen) 2. Relative angle display (switch screens using up and down arrows) 3. Relative zero point reset (6-digit numeric keys to reset the zero point) 4. Alarm angle setting (switch to the alarm angle setting interface to set the alarm angle value).

Installation of LVG726T dynamic tilt sensor for posture control during construction of rotary drilling rig

The inclination sensor is installed at the end of the drill rod, which can achieve real-time dual-axis attitude measurement under the motion conditions of the drill rod structure. The inclination sensor installed on the chassis of the vehicle can accurately measure the attitude of the vehicle body relative to the horizontal plane.

Tilt sensor, safety detection for basket balance control

Working at heights poses significant dangers. To ensure the stability of the吊篮 (suspended basket), one can choose the LVT533T three-axis dual relay output tilt leveling control switch, which can be installed on the吊兰 (suspension crane) mechanical bucket to determine the tilt angle of the吊篮, preventing operational errors caused by the operator's unfamiliarity with the high-altitude environment.

Safety operation and leveling control of hydraulic lift platforms and aerial work vehicles

Lifting platforms/aerial work vehicles are crucial for high-stroke lifts or lifting equipment, as the angle measurement and control of the operating platform relate to the safety of the operators. Therefore, it is necessary to measure, control, and alarm the tilt angle of the operating platform and the entire equipment base. The dual-axis tilt sensor LVT526T and the omnidirectional tilt switch LVT542T are suitable for this function. Both single-axis and dual-axis tilt switches are based on improved MEMS technology. The products have analog output and digital outputs such as RS485, RS232, and CAN, offering high accuracy, vibration resistance, and long-term stability.

Shield tunneling machine

The shield tunneling machine, also known as a shield tunnel boring machine, is a specialized piece of engineering machinery used for tunnel excavation. The basic working principle of the shield machine is a cylindrical steel component that advances along the axis of the tunnel while excavating the soil. The shell of this cylindrical component is what is commonly referred to as the shield, which provides temporary support for the excavated but unlined sections of the tunnel. It not only bears the pressure from the surrounding soil layers but also withstands groundwater pressure and keeps groundwater at bay. Operations such as excavation, soil removal, and lining are generally carried out under the protection of the shield of the shield machine. It is widely used in subways, railways, highways, municipal projects, and hydropower tunnels.
