Description

Technical Field

[0001] This utility model relates to the field of steel structure measurement technology, and in particular to a semi-automatic device suitable for measuring high-rise and large curved surface steel structures in space. Background Technology

[0002] In recent years, with the continuous development and progress of my country's construction industry, the application of steel structures in building construction has become increasingly widespread. Currently, my country's super high-rise steel structure buildings and large-span steel structure forms have broken through the traditional single form and are developing towards diversification and complexity. Many new steel structure forms and special shapes have emerged, such as large inclined columns, large cantilever trusses, curved torsion trusses, curved reticulated shells, irregular ribbon skirts, and large-span steel structure bridges spanning lines, rivers, and canyons in super high-rise buildings. The adjustment and measurement during construction, the monitoring of deformation and displacement, and the monitoring during operation have led to an increasing demand for construction measurement and monitoring. The number of measurement and monitoring points is also increasing, which puts forward higher requirements for construction measurement and monitoring.

[0003] Chinese patent CN215115925U discloses a "Steel Structure Monitoring Device," comprising a monitoring prism and a fixing device. The fixing device includes a base, a screw, and a locking nut. The base is used to fix the device to the measurement point of the steel structure, and the screw is adapted to the locking nut and fixed to the base. The monitoring prism includes a bracket, a mirror body, and a knob. The bracket has a first through hole and a second through hole. The screw passes through the first through hole and connects to the locking nut, and the connecting rod of the knob passes through the second through hole and connects to the mirror body. This solution fixes the fixing device to the measurement point of the steel structure, installs the assembled monitoring prism on the fixing device, and uses matching connectors to fix the mirror body to the bracket. The bracket is fixed to the base via matching connectors. The reflection angle of the monitoring prism is adjusted according to the position of the measuring instrument for automatic monitoring.

[0004] The above-mentioned solutions are problematic for super high-rise steel structure buildings and large-span steel structure buildings. Due to the large amount of high-altitude work involved in the positioning of special points, the measurement assistants need to climb to high places, which poses a certain risk of falling from height. In order to solve the above problems, there is an urgent need to design a semi-automatic device suitable for measuring high-rise and large curved steel structures in space. Utility Model Content

[0005] The purpose of this invention is to provide a semi-automatic device suitable for measuring high-rise and large curved steel structures in space, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a semi-automatic device suitable for measuring high-rise and large curved steel structures in space, including an omnidirectional moving magnetic trolley, which includes a universal magnetic wheel, a drive motor, a magnetic wheel connector and an aluminum alloy lightweight vehicle body base.

[0008] The system comprises four omnidirectional magnetic wheels arranged symmetrically in a rectangular configuration. Each magnetic wheel is connected to a drive motor, and a magnetic wheel connector is located above each wheel. Above the magnetic wheel connector is an aluminum alloy lightweight vehicle body floor. Above the aluminum alloy lightweight vehicle body floor are a rechargeable battery, a wire connection integrated box, a remote control signal receiver, a small anti-fall parachute, and a miniature solar panel. A light signal receiver is centrally connected to the aluminum alloy lightweight vehicle body floor. The remote control signal receiver is used to receive command signals sent by the wireless remote control panel.

[0009] Furthermore, the universal magnetic wheel includes an annular permanent magnet, a central hub, an outer cover for the universal magnetic wheel, and an inner cover for the universal magnetic wheel;

[0010] The central hub is located in the middle of the annular permanent magnet, the outer cover of the universal magnetic wheel is located on the outside of the annular permanent magnet, the inner cover of the universal magnetic wheel is located on the inside of the annular permanent magnet, and a silicone tire is installed on the surface of the annular permanent magnet.

[0011] Furthermore, the lower part of the magnetic wheel connector is hinged to the central wheel hub bearing, and the magnetic wheel connector is provided with a 360° fully rotating movable disk directly above the universal magnetic wheel.

[0012] Furthermore, the rechargeable battery includes a rechargeable battery body, a rechargeable battery charging inlet terminal, and a rechargeable battery discharging outlet terminal.

[0013] The rechargeable battery body is provided in four groups and is correspondingly arranged with the drive motor. The micro solar panel charges the rechargeable battery body through the charging inlet terminal of the rechargeable battery body. The rechargeable battery body is electrically connected to the drive motor through the discharging outlet terminal of the rechargeable battery body. Each group of rechargeable battery bodies is provided with an insulating protective outer packaging.

[0014] Furthermore, the optical signal receiving device includes a 360° prism and a retractable prism rod. A threaded hole is provided below the 360° prism. One end of the retractable prism rod is provided with a stainless steel tip, and the other end is provided with a self-tapping thread. The retractable prism rod is threadedly connected to the threaded hole below the 360° prism through the self-tapping thread.

[0015] Furthermore, two wire connection integration boxes are symmetrically arranged on the left and right sides of the lightweight vehicle body floor plate, and a waterproof cover that can be detached and opened is provided on the top of the wire connection integration box.

[0016] Furthermore, the remote control signal receiver is disposed within the wire connection integration box, and the remote control signal receiver employs a superheterodyne receiver module.

[0017] Furthermore, the small anti-fall parachute includes a small anti-fall parachute tube and a small anti-fall parachute body. The small anti-fall parachute tube is symmetrically arranged on both sides of the optical signal receiving device and located between the two wire connection integration boxes. The small anti-fall parachute body is stored in the small anti-fall parachute tube.

[0018] Furthermore, the micro solar panel includes a micro solar panel body and a lightweight micro solar panel bracket. The micro solar panel body is composed of several micro solar panel body modules. After the several micro solar panel body modules are combined, they are inserted into the lightweight micro solar panel bracket. The lightweight micro solar panel bracket is symmetrically arranged at the upper and lower ends of the lightweight vehicle body floor.

[0019] Furthermore, the wireless remote control panel uses a transmitter module and an operating handle to send command signals to the remote control signal receiver.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model features four omnidirectional magnetic wheels arranged symmetrically in a rectangular configuration on all sides. Above each wheel is a connecting component, and above that is a lightweight aluminum alloy chassis. Above the chassis is a rechargeable battery, a charging / discharging wire connection box, a remote control signal receiver, a small anti-fall parachute, and a foldable, easily pluggable micro solar panel. A light signal receiver is centrally connected to the chassis. This receiver receives command signals from a wireless remote control panel. This design allows the device to adapt to measurement work on various high-rise and large-curved steel structures where observation is difficult. It improves the flexibility and safety of high-altitude observations, avoids missing or inaccurate measurements of critical points, and reduces errors and time consumption from frequent point-shifting of measuring instruments and total stations, thus improving measurement safety and efficiency.

[0022] 2. When using this utility model, mark the observation point with a punch or attach a self-adhesive reflector beforehand. Fully charge the rechargeable battery beforehand. Insert the foldable and pluggable micro solar panel body onto the foldable and pluggable micro solar panel lightweight bracket. Unfold the installed foldable and pluggable micro solar panel body according to the direction of sunlight. Install the 360° prism and the telescopic prism rod as a whole and tighten them. Adjust the telescopic prism rod to a fixed height according to the measurement needs and record it. Then install the 360° prism and the telescopic prism rod in the center of the omnidirectional moving magnetic trolley and tighten them. Check whether the circuit switch is normal. After the surveyor sets up the measuring instrument, the measurement assistant carries the adjusted device to the vicinity of the steel structure to be measured and places the device on the surface of the steel structure. On a relatively flat surface, holding the wireless remote control panel, turn on the signal switch and test the "forward," "backward," "left," and "right" movements. After confirming that the movements are executed correctly, the omnidirectional magnetic trolley is remotely controlled to the measurement point on high-rise and large curved steel structures, especially at higher parts of the steel structure, curved surfaces, and areas where measurement assistants cannot easily climb. After reaching the approximate measurement point, fine-tuning is performed, and the "point-capture" action is activated. Then, the instrument is started to measure the point and the coordinate data is recorded. After measuring a single point, the "forward" and "backward" movements are activated to move to the next point. After the measurement work for the day or session is completed, the measurement assistants retrieve the device. This effectively solves the problems of falling danger and low work efficiency when dealing with high-rise and large curved steel structures.

[0023] 3. This utility model incorporates a rechargeable battery and a foldable, easily pluggable micro solar panel. When the omnidirectional magnetic trolley's power is insufficient, inserting the foldable, easily pluggable micro solar panel switches to solar charging power mode, allowing the measurement work to continue. Alternatively, the remaining power can be used to return the device to its original position and manually replace the spare battery. Specifically, 1-2 sets of batteries can be reserved depending on the number of measurement points or the omnidirectional magnetic trolley's range. Each set contains four sets of rechargeable batteries for the entire vehicle. In emergency situations such as the semi-automatic measuring device losing power at high altitudes, losing magnetic force, or having insufficient magnetic force, and the device is at risk of falling, a small anti-fall parachute will automatically deploy. In the backup mode, the parachute will be manually deployed. Measurement support personnel will retrieve the device from the point of impact, and after inspection, the next measurement work can proceed. This improves the device's effectiveness and lifespan.

[0038] like Figure 1-9As shown, this utility model provides a semi-automatic device suitable for measuring high-rise and large-curved steel structures in space, including an omnidirectional magnetic trolley. The omnidirectional magnetic trolley includes universal magnetic wheels 1, drive motors 2, magnetic wheel connectors 3, and a lightweight aluminum alloy chassis 4. Four universal magnetic wheels 1 are arranged symmetrically in a rectangular configuration.

The material of the aluminum alloy lightweight vehicle body floor 4 is aluminum alloy. A rechargeable and dischargeable battery 5, a wire connection integrated box 6, a remote control signal receiver 7, a small anti-fall parachute 8, and a miniature solar panel 9 are arranged on the top of the aluminum alloy lightweight vehicle body floor 4; a light signal receiving device 10 is connected through the center of the aluminum alloy lightweight vehicle body floor 4; the remote control signal receiver 7 is used to receive command signals sent by the wireless remote control panel 71.

[0039] Specifically, compared with traditional measuring devices, this utility model, by setting up an omnidirectional moving magnetic trolley and an optical signal receiving device 10, allows the device to adapt to the measurement work of various high-rise and large curved steel structures that are difficult to observe and measure. It also improves the flexibility of observation and measurement, enhances the safety of high-altitude observation and measurement, avoids the inability to see or measure key points, and reduces the error and time consumption of frequent point switching of measuring instruments and total stations, thereby improving the safety and efficiency of measurement.

[0040] Combination Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the universal magnetic wheel 1 includes an annular permanent magnet 11, a central hub 12, an outer cover 13, and an inner cover 14.

[0041] Preferably, the annular permanent magnet 11 is the most important structure of the omnidirectional magnetic wheel 1, the source of magnetic force for the entire omnidirectional magnetic wheel 1, and the source of magnetic force for the omnidirectional moving magnetic trolley to adhere to the surface of the steel structure. The material of the annular permanent magnet 11 is neodymium magnet (neodymium-iron-boron) or samarium cobalt magnet (Sm-Co), which can provide strong magnetism.

[0042] Preferably, the central hub 12 is located in the middle of the annular permanent magnet 11 and is driven by the drive motor 2. The drive motor 2 is a high-torque DC motor that drives the omnidirectional magnetic wheel 1 to roll. Each omnidirectional magnetic wheel 1 corresponds to a single drive motor 2, and a total of four are provided. Each drive motor 2 is connected to a single set of rechargeable and dischargeable batteries 5. To reduce structural weight, the central hub 12 is made of lightweight aluminum alloy. The outer cover 13 of the omnidirectional magnetic wheel is located on the outside of the annular permanent magnet 11. The inner cover 14 of the force wheel is disposed on the inner side of the annular permanent magnet 11. The outer cover 13 and the inner cover 14 of the universal magnetic force wheel are used to seal and isolate the annular permanent magnet 11 from direct contact with external water, dirt, rust, scale, paint, welding spatter, etc. In order to reduce the weight of the structure, the outer cover 13 and the inner cover 14 of the universal magnetic force wheel are both made of lightweight aluminum alloy. A silicone tire 15 or a thin coating is installed on the surface of the annular permanent magnet 11 to protect the annular permanent magnet 11 and increase the friction.

[0043] In a preferred embodiment of this utility model, four sets of magnetic wheel connectors 3 are provided, each set being connected to a single universal magnetic wheel 1. The lower part of the magnetic wheel connector 3 is hinged to the bearing of the central hub 12. A 360° fully rotating movable disc is provided directly above the universal magnetic wheel 1 on the magnetic wheel connector 3, which allows the universal magnetic wheel 1 to perform operations such as "straight ahead" and "turning" under the control of the wireless remote control panel.

[0044] Combination Figure 1 and Figure 5 As shown in the preferred embodiment of this utility model, the rechargeable battery 5 includes a rechargeable battery body 51, a rechargeable battery charging inlet terminal 52, and a rechargeable battery discharging outlet terminal 53. The rechargeable battery body 51 is a rechargeable battery, and four groups are provided, corresponding to the drive motors 2. Each group is responsible for supplying power to the four drive motors 2: left front, right front, left rear, and right rear. The rechargeable battery charging inlet terminal 52 is the charging port of the battery body 51. It can be charged by an external mobile charging power source (AC / DC) during non-operating time, or during operating time or in open outdoor sunny non-operating time, by using the built-in micro solar panel 9 of this device to charge the battery body 51 through the battery charging inlet terminal 52. The battery body 51 is electrically connected to the drive motors 2 through the battery discharging outlet terminal 53.

[0045] Combination Figure 2 , Figure 3 and Figure 6As shown in the preferred embodiment of this utility model, the optical signal receiving device 10 includes a 360° prism 101 and a telescopic prism rod 102. The 360° prism 101 is the object that receives optical signals from measuring instruments, total stations, etc., at the point to be measured by this measuring device. Different constants, different precisions, and different specifications of prisms are selected according to the project characteristics, design, and construction acceptance specifications. Existing 360° prisms are commonly used general-purpose parts in the market and do not require special design, procurement, or processing.

[0046] The retractable prism rod 102 is a frosted aluminum alloy rod. To reduce the structural weight, it can be designed as a hollow aluminum alloy rod with a certain wall thickness and strength. An adjusting screw is installed inside, which can extend or retract the length according to the project requirements.

[0047] Specifically, a threaded hole is provided below the 360° prism 101, and one end of the telescopic prism rod 102 is provided with a stainless steel tip, while the other end is provided with a self-tapping thread. The telescopic prism rod 102 is threadedly connected to the threaded hole below the 360° prism 101 through the self-tapping thread, which facilitates disassembly or replacement.

[0048] In a preferred embodiment of this utility model, the wire connection integrated box 6 is a fixed integrated box for the battery charging inlet terminal 52 and the battery discharging outlet terminal 53, and is fixed to the aluminum alloy lightweight vehicle body base plate 4. Two wire connection integrated boxes 6 are symmetrically arranged on the left and right sides of the aluminum alloy lightweight vehicle body base plate 4. The top of the wire connection integrated box 6 is provided with a removable waterproof cover to prevent rainwater, dust, sunlight and other factors from corroding the wires and to prevent damage such as aging, wear and tear, and short circuits.

[0049] In a preferred embodiment of this utility model, the remote control signal receiver 7 is disposed in the wire connection integrated box 6. The remote control signal receiver 7 serves as a component for measuring assistants to remotely control the device and receive command signals. It adopts a superheterodyne receiving module to receive and execute command signals such as "forward", "backward", "left turn", "right turn", "stop", and "capture point".

[0050] Combination Figure 1 , Figure 7 and Figure 8 As shown, in a preferred embodiment of the present invention, the small anti-fall parachute 8 includes a small anti-fall parachute tube 81 and a small anti-fall parachute body 82. The small anti-fall parachute tube 81 is symmetrically arranged on both sides of the optical signal receiving device 10 and located between the two wire connection integration boxes 6. The small anti-fall parachute body 82 is stored in the small anti-fall parachute tube 81. It is a protective device for the entire semi-automatic measuring device to be activated and opened in emergency situations such as no running power at high altitude, loss of magnetism, or insufficient magnetism, to prevent the entire semi-automatic measuring device from being damaged by falling.

[0051] In a preferred embodiment of this utility model, the micro solar panel 9 is configured as a foldable and easily pluggable micro solar panel. The micro solar panel 9 includes a micro solar panel body 91 and a micro solar panel lightweight bracket 92. The micro solar panel body 91 is composed of several micro solar panel body panels. After the several micro solar panel body panels are combined, they are inserted into the micro solar panel lightweight bracket 92. The micro solar panel lightweight bracket 92 is symmetrically arranged at the upper and lower ends of the lightweight vehicle body floor 4, with two sets at the front and rear of the vehicle. When there is a charging requirement, the micro solar panel body 91 is inserted into the micro solar panel lightweight bracket 92. When there is no charging requirement, the several micro solar panel body panels can be folded and retracted together. Alternatively, to reduce the overall weight and load of the device, the micro solar panel body panels can be removed or detached, and the rechargeable battery 5 provides power to the device.

[0052] In a preferred embodiment of this utility model, the wireless remote control panel 71 serves as a component for measuring assistants to remotely control the device and transmit command signals. It employs a transmitter module and an operating handle, allowing real-time viewing of the device and prism rod, and sending command signals such as "forward," "backward," "left turn," "right turn," "stop," "capture point," "unfold solar umbrella," "fold solar umbrella," and "emergency umbrella opening" to the remote control signal receiver 7.

[0053] In use, the observation point should be marked with a punch mark or a self-adhesive reflector should be attached beforehand. The rechargeable battery 5 should be fully charged beforehand. The micro solar panel body 91 should be inserted into the micro solar panel lightweight bracket 92 and unfolded according to the direction of sunlight. The 360° prism 101 and the telescopic prism rod 102 should be installed as a whole and tightened. The telescopic prism rod 102 should be adjusted to a fixed height or length, such as 300mm, according to the measurement needs and recorded. Then, the 360° prism 101 and the telescopic prism rod 102 should be installed in the center of the omnidirectional moving magnetic trolley and tightened. Check whether the circuit switch is normal. After the surveyor sets up the measuring instrument, the measurement assistant carries the calibrated omnidirectional magnetic trolley, 360° prism 101, and retractable prism rod 102 to the vicinity of the steel structure to be measured. The device is placed on a relatively flat surface of the steel structure. Holding the wireless remote control panel, the signal switch is turned on, and the "forward," "backward," "left," and "right" movements are tested. After confirming that the movements are executed correctly, the omnidirectional magnetic trolley is officially remotely operated to the measurement point on the super high-rise and large curved surface steel structure, especially at higher points of the steel structure and on curved surfaces where it is difficult for the measurement assistant to climb. Once the approximate location of the point to be measured is reached, fine-tuning is performed, and the "point-capture" action is activated. Then, the instrument is started to measure the point and the measurement coordinate data is recorded. If the omnidirectional magnetic trolley moves to a distance where fine-tuning is difficult due to visual limitations, a telescope can be used as an aid. After measuring a single point, the "forward" and "backward" actions are activated to move to the next point. After the measurement work for the day or the current session is completed, the measurement assistant retrieves the device. Compared with traditional measurement methods, this device effectively solves the problems of falling danger and low work efficiency when dealing with high-rise buildings and large curved steel structures in space.

[0054] When the omnidirectional magnetic trolley's power is insufficient, it can switch to solar charging power mode. This allows it to continue measurement work using the micro solar panels 9, or use the remaining power to return the device to its original position and manually replace the spare batteries. Specifically, 1-2 sets of batteries can be reserved, depending on the number of measurement points or the omnidirectional magnetic trolley's range. Each set includes four sets of batteries 5 for the entire vehicle. In emergency situations such as the entire semi-automatic measuring device losing power at high altitudes, losing magnetic force, or having insufficient magnetic force, and posing a risk of falling, the small fall-proof parachute 8 will automatically deploy. In backup mode, the small fall-proof parachute 8 will be manually deployed. Measurement support personnel will retrieve the device from the point of impact. After verification, the next measurement will proceed, thereby improving the device's effectiveness, safety, and lifespan.

[0055] The working principle of this utility model is as follows: When in use, the measurement assistant carries the calibrated omnidirectional magnetic trolley, 360° prism 101, and retractable prism rod 102 to the vicinity of the steel structure to be measured. The device is placed on a relatively flat surface of the steel structure. Holding the wireless remote control panel, the signal switch is turned on, and the "forward," "backward," "left," and "right" actions are tested. After the actions are executed without error, the omnidirectional magnetic trolley is officially remotely operated to the measurement point of the super high-rise and large curved surface steel structure, especially the high part of the steel structure, the curved surface of the space, and the places that are difficult for the measurement assistant to climb to reach. After reaching the approximate position of the measurement point, fine-tuning and positioning are performed, the "capture point" action is operated, and then the instrument is started to measure the point and the measurement coordinate data is recorded. This device reduces the danger of measurement assistants climbing high up steel structures. The omnidirectional magnetic trolley can move and position itself on the steel structure surface according to remote control commands, thereby reducing the physical exertion of measurement assistants. At the same time, adding a miniature solar panel 9 can extend the omnidirectional magnetic trolley's operating range, and adding a small anti-fall parachute 8 can improve the device's effectiveness, safety, and service life.
