Description

Technical Field

[0001] The utility model relates to the technical field of building quality detection, in particular to an auxiliary inspection device for the outer wall of a chimney. Background Art

[0002] In modern industrial production, chimneys, as an important emission facility, play a key role in emitting waste gas into the atmosphere. With increasingly stringent environmental regulations, the traditional dry flue gas emission method has been gradually replaced by wet flue gas emission to meet higher environmental standards. However, the emission of wet flue gas not only poses a greater threat to the structural integrity of the chimney, but also poses new challenges to its maintenance and inspection. Especially in the inspection of concrete chimneys with a height of more than 100 meters, due to their height and structural characteristics, the traditional manual inspection method has significant safety risks and operational limitations.

[0003] Some attempts have been made to use a variety of new electronic devices or automated equipment, such as drones for inspection. However, due to interference from strong magnetic fields in power plants, steel mills and other areas, drones are unable to fly normally in most cases. In addition, drones on the market have limited flight time and cannot complete inspections quickly and comprehensively at one time, limiting the inspection of chimney outer walls. Another example is the use of wall-climbing robots for inspection. Climbing robots are mostly applicable to pure steel structures due to the principle of magnetic attraction. On concrete chimneys, there is a risk of falling from high altitudes due to uneven thickness of the protective layer and spacing of steel bars, and uneven surfaces. In addition, the equipment requires professional personnel to operate and has a high cost, which has certain limitations. Utility Model Content

[0035] The inspection and recording device 8 can display the height from the ground. The device is provided with a camera which can swing up and down, left and right, take pictures, and can be interconnected with the electronic control device through wireless communication methods, such as Bluetooth. When defects or damages are found, the electronic control device can be used to remotely control the taking of pictures and recording.

[0036] The electronic control device may be a mobile phone or a remote controller with a display screen.

[0037] Please continue to see Figure 1 In some embodiments, the angle of the clamping space is designed to be 85° to 95°. By cross-connecting at least two inclined rods at one end with a tee, the clamping space is formed, so that the device can be applied to chimneys of most specifications, while ensuring stability during the inspection process.

[0038] Preferably, the angle of the clamping space is 90°.

[0039] The upper inclined rod 1 is shorter than the lower inclined rod 2 and has the same diameter, so as to facilitate the stability and operability of the device. Specifically, the upper inclined rod 1 is 30 cm long and 32 mm in diameter. The lower inclined rod 2 is 60 cm long and 32 mm in diameter.

[0040] Please continue to see Figure 1 The device further includes: a balance bar 10, which is connected to at least two lower inclined bars 2 and is arranged near the end where the universal wheel is located; it is used to maintain the overall balance of the device and prevent the inspection device from turning over as a whole due to excessive wind force. For the sake of portability and overall weight control, the balance bar 10 is about 2.5 meters long and is preferably made of light materials such as bamboo poles and light alloys. The weight should not be too large. The balance bar 10 can be fixed to the end of the lower inclined bar 2 near the universal wheel by a binding or locking mechanism.

[0041] See also Figure 3 In some embodiments, the balancing pole 10 includes a central axis 101 and support arms 102 symmetrically distributed along the length direction of the central axis 101 and around the central axis 101;

[0042] One end of each support arm 102 is fixedly connected to the central axis 101, and the other end freely extends to form a free end;

[0043] The support arm 102 is provided with a plurality of weight-adjustable counterweights 103 , and the counterweights 103 can be slidably adjusted in position along the length direction of the support arm 102 ;

[0044] Both ends of the central axis 101 are respectively connected to at least two lower inclined rods 2 and are arranged near the ends where the universal wheels are located.

[0045] In one embodiment, the counterweight block 103 is slidably disposed on the support arm, and the counterweight block is driven by a driving motor (not shown in the figure) to slide along the length direction of the support arm as a whole to adjust the position.

[0046] The support arm 102 is provided with a rack 107 along the length direction of the support arm (each support arm 102 is provided with a rack 107, which is a simplified drawing in the figure). The rack 107 can be fixed on one side of the support arm 102 or embedded in the support arm 102; the adjustment mechanism includes: a gear 105 and a connecting rod 106, the gear 105 is meshed with the rack 107 on the support arm 102, one end of the connecting rod 106 is connected to the gear 105, and the other end of the connecting rod 106 is connected to a driving motor, and the driving motor is used to drive the gear 105 to rotate and drive the rack 107 to move;

[0047] Each counterweight 103 is provided with an internal gear (not shown in the figure) that cooperates with the gear 105. When the gear 105 rotates, the rack 107 is engaged with the internal gear, driving the counterweight 103 to move along the length direction of the support arm 102, thereby adjusting the center of gravity position of the balance pole 10 and achieving the adjustment of the balance state.

[0048] The location and length of the rack 107 are determined according to the moving range of the counterweight 103 and the length of the support arm 102 to ensure that the counterweight can move on the entire support arm to achieve the purpose of adjusting the balance.

[0049] In order to achieve that the balance pole can adapt to the wind direction and adjust its posture adaptively to achieve the best balance state, in some embodiments, the balance pole 10 is provided with a wind direction sensor 109 for detecting the current wind direction;

[0050] The wind direction sensor 109 is connected to a driving control unit (not shown in the figure) of the driving motor. The driving control unit drives the driving motor of the counterweight according to the data of the wind direction sensor 109, changes the position of the counterweight, and maintains the balance state of the balance bar by adaptively adapting to the wind direction, thereby achieving instant response to changes in wind direction and adaptive adjustment of the balance state, so that the auxiliary inspection device can be better suited for operations in windy weather.

[0051] In some embodiments, each support arm 102 of the balance pole 10 is also provided with a wind receiving surface 114 (which can be provided on each support arm in the figure). When the wind acts on the wind receiving surface 114, the wind receiving surface will transmit the wind data to the driving control unit of the driving motor by wireless means, thereby controlling the counterweight to move accordingly to offset the imbalance caused by the wind. Specifically, the wind receiving surface 114 can be a sail made of deformable canvas or other flexible materials, and a wind sensor is provided on the wind receiving surface 114 to detect the size of the wind and has a sending function.

[0052] The universal wheel is made of 304 stainless steel, with a wheel diameter of about 60 mm, a wheel width of 32 mm, an installation height of 90 mm, a top plate size of 94 mm×64 mm, a top plate thickness of about 3 mm, and the top plate can be connected to one end of the upper oblique rod 1 and the lower oblique rod 2 by welding.

[0053] In this embodiment, the first tee 6 and the second tee 7 are right-angled internal thread tees, which are in the shape of a "corner" and made of 304 stainless steel. They are 55 mm in height and 32 mm in diameter. They are used to connect the upper oblique rod 1, the ridge rod 3 and the lower oblique rod 2. The middle part of the "one-way" in the internal thread tee is welded to the steel ring 11. The steel ring 11 is solidly welded and made of 304 stainless steel. The inner diameter is 30 mm and the wire diameter is 3 mm. It is used to hang a safety buckle and perform a hanging device.

[0054] The chimney auxiliary inspection device provided in the embodiment of the present application is easy to carry. It is low in cost, simple and easy to operate, does not require manual hanging basket operation, is less affected by environmental factors such as weather and magnetic field, can improve inspection efficiency, and can reduce safety risks in the project process. It has broad application prospects in the field of existing chimney detection and maintenance technology, and has good economic and social benefits.

[0059] (2) Connect the two upper inclined rods 1 to the first tee 6;

[0060] (3) Connect the two lower oblique rods 2 to the second three-way connection 7; if necessary, in this step, it is also necessary to use a binding rope to evenly tie the balance rod 10 to the end of the lower oblique rod 2 near the universal wheel, about 8 cm away from the end of the lower oblique rod 2.

[0061] The order of steps (2) and (3) can be swapped.

[0062] (4) The inspection and recording device 8 is installed at the middle connecting piece of the spine 3. It can be fixed by bolting or tying.

[0063] (5) Connect the safety rope to the steel ring 11 with a safety buckle. Note that the length of the safety rope should be close to the height of the chimney. Before going up the chimney, check whether the safety rope meets the length requirement.

[0064] After the installation of the device is completed, the aerial workers will check whether the universal wheel is normal, whether the rope and the inspection and recording device 8 are installed firmly. After the self-inspection is qualified, the aerial workers will contact the ground personnel with a walkie-talkie, and the ground personnel will use the mobile phone and the recording device to interconnect and debug until the equipment's height parameters and photo operation are in normal state.

[0065] During the specific construction, in order to facilitate the coordination and timely communication with the ground personnel, the high-altitude workers also need to carry some communication equipment to the top of the chimney, and the number of workers should be 2-3 people.

[0066] Clamp the clamping spaces formed by at least two upper inclined rods 1 and at least two lower inclined rods 2 on the outer wall of the chimney;

[0067] Slowly lower the suspension rope so that the chimney outer wall auxiliary inspection device moves up and down along the chimney outer wall using universal wheels;

[0068] The appearance of the outer wall of the chimney is inspected by the probe of the inspection and recording device 8, and the inspection and recording device 8 is remotely controlled by the electronic control device to record the appearance defects or damages found.

[0069] In the embodiments of the present application, with the aid of the auxiliary inspection device provided in the aforementioned embodiments, the appearance of the outer wall of the chimney can be conveniently inspected through the above steps without the need to build a complicated hanging basket structure, and the operator does not need to go up and down with the potential safety risks that may exist, which can facilitate the rapid, effective and safe inspection of the outer wall of the chimney.

[0075] The movement state of the chimney outer wall auxiliary inspection device is adjusted and corrected to restore it to a normal movement state.

[0076] In this embodiment, after the device is debugged, two high-altitude workers can use a safety rope to lower the device along the outer wall of the chimney. During the lowering process, a ground worker should always use a telescope to pay attention to the descending state of the device. In case of abnormal descent such as tilting or rotation of the device, the high-altitude worker operating the device at the top of the chimney should be informed by a walkie-talkie in time to make timely adjustments and corrections. Another ground worker uses a mobile phone connected to the inspection and recording device 8 to observe the defects and damage of the tube wall. If defects and damage of the tube wall are found, the high-altitude worker operating the device at the top of the chimney should be informed by a walkie-talkie in time to stop the descent of the device in time, and the defects and damage of the tube wall should be recorded by taking photos with the mobile phone, and the height and direction of the defects and damage should be recorded, so as to facilitate the subsequent summary and collation of the chimney outer wall defect and damage report.

[0077] The chimney outer wall auxiliary inspection device provided by the embodiment of the utility model is convenient for assisting in realizing a rapid, effective and safe inspection of the chimney outer wall.

[0078] Furthermore, it can adapt to strong wind environment, and can still maintain overall stability and inspection reliability in strong wind environment.
