Description

Technical Field

[0002] After long-term use, actual buildings are eroded by rain, and the coating layer on the outer wall is prone to bulging. If it is not repaired in time, it is easy to cause the wall skin to fall off, causing hidden dangers such as falling objects from high altitude and injuring pedestrians. Because the outer wall coating of the building is not convenient to observe on the ground, it is usually carried out by manual on-site inspection by riding in a hanging basket. After the problem is found, the bulging defective area is promptly removed. The current urban building safety detection device is not convenient for laser prediction detection, and it is not convenient for staff to efficiently learn about the wall bulging situation. The detection efficiency is low and it is easy to miss the inspection. At the same time, it is normal for the wall to have certain concave and convex errors during construction. It is not convenient to pressure test whether the inside of the wall bulge is hollow without damaging the wall, which is easy to cause unnecessary damage to the wall.

[0035] Among them, the mobile traction part 1 also includes: a pulley 103, a moving belt 104 and a traction frame 105. Two pulleys 103 are rotatably installed on both sides of the mounting wheel frame 101, and the four pulleys 103 are grouped in pairs; there are two moving belts 104, and the two moving belts 104 are respectively transmitted on the two pulleys 103 on the same side of the sleeve; seven circles of through holes are respectively opened on the two moving belts 104; the adsorption control part 2 includes: an air suction pump 201, an air suction box 202 and a limit strip 2021, the air suction pump 201 is fixedly installed on the mounting wheel frame 101; the air inlet pipe of the air suction pump 201 is connected to the air suction box 202 on the same side; two air suction boxes 202 are fixedly installed on the mounting wheel frame 101 by bolts, and the two air suction boxes 2 02 are connected by a hose; two limit strips 2021 are fixedly installed on the two suction boxes 202; the two moving belts 104 are respectively located between the two limit strips 2021 on the same side; seven through grooves are respectively provided at the bottom of the two suction boxes 202, and the through grooves at the bottom of the two suction boxes 202 are respectively aligned with the through holes on the moving belt 104, and the adsorption control part 2 is adopted, and the air pressure generated by the suction can be used in conjunction with the moving belt 104, and it can be attached to the outer wall of the building for movement, which can facilitate standard bulge detection work and avoid shaking caused by wind and other factors. The negative pressure adsorption is used to fit the outer side of the building to ensure the detection stability, and the rolling conveyance of the moving belt 104 can prevent wear on the outer side of the building.

[0036] Among them, the bulge detection part 3 includes: a pressing and lifting shaft 301 and a floating spring 302. Two pressing and lifting shafts 301 are slidably installed on the mounting wheel frame 101; floating springs 302 are respectively sleeved on the two pressing and lifting shafts 301; the bulge detection part 3 also includes: a roller frame 303 and a fitting pressing roller 304.

By using the hollow confirmation part 4, the wall with a hollow inside the outer wall bulge can be used. When pressure is applied, the outer wall skin or the insulation layer can be pressed inwards, and the bulge caused by normal construction errors The principle that there is no hollow inside and it will not be pressed in can be used for safe detection. This can prevent the bulge from being missed and can also avoid the normal raised bulge from being misjudged and removed, causing unnecessary wall damage. The detection of this structure is direct and accurate, which can ensure the accuracy of bulge detection on the outer surface of the wall. When the wheel frame 101 is installed and moved on the outer wall, if there is a bulge, it will squeeze the fitting pressing roller 304. At this time, the elastic force of the floating spring 302 is relatively small, and it only plays the role of elastically pushing the fitting pressing roller 304 to fit the wall surface. The electric push rod 102 pushes the roller frame 303 to drive the fitting pressing roller to fit the wall surface. 304 presses the bulge on the wall. If the bulge is squeezed inward by the pressing roller 304, the roller frame 303 will be separated from the microswitch 402, and the microswitch 402 will control the upper alarm light 5011 to go out, indicating that there is a safety hazard here and the wall skin needs to be removed for repair. If the bulge is not compressed by the pressing roller 304, the roller frame 303 will not be separated from the microswitch 402, and the upper alarm light 5011 will remain on to alarm. The staff can know that the current bulge is a normal bulge. The judgment method is simple and direct, avoiding unnecessary losses caused by misjudgment.

[0037] The anti-falling component 5 includes: an anti-falling collection box 501, an alarm light 5011, a lifting slide shaft 502 and a pressing plate 503.

Dustproof rubber sheets 504 are fixedly installed on both sides of the pressing plate 503, and the sides of the two dustproof rubber sheets 504 are fixedly installed inside the anti-falling collection box 501; the dustproof rubber sheet 504 is a soft elastic structure; an anti-falling micro switch 505 is fixedly installed inside the anti-falling collection box 501; the anti-falling micro switch 50 5 is located below the pressing plate 503; a row of V-shaped spring pieces 506 are fixedly installed inside the anti-falling collection box 501; the end of the V-shaped spring piece 506 is fixedly installed at the bottom of the pressing plate 503; the anti-falling microswitch 505 is electrically connected to the alarm light 5011 below; the microswitch 402 is electrically connected to the alarm light 5011 above; the anti-falling microswitch 505 is used to detect the broken outer wall skin, and the anti-falling part 5 is used to collect the fallen wall skin to prevent the safety hazard of the wall skin falling off when the pressing roller 304 presses the wall surface.

The structure is simple and reasonable to avoid the safety accident caused by the continuous falling wall skin that the anti-falling part 5 cannot take over completely. The prompting method of this structure is simple and intuitive, and the two alarm lights 5011 used can be distinguished by the color of the lights.

[0038] Embodiment 2, on the basis of embodiment 1, the wall side fitting part 6 comprises: a rotating mounting arm 601, a rotating shaft 602, a torsion spring 603, a wall-adhering arm 604 and a wall-adhering wheel 6041, the rotating mounting arm 601 is fixedly mounted on the side of the mounting wheel frame 101; a rotating shaft 602 is fixedly mounted on the rotating mounting arm 601, and a torsion spring 603 is sleeved on the rotating shaft 602; a wall-adhering arm 604 is rotatably mounted on the rotating shaft 602; an end of the torsion spring 603 is connected to the rotating shaft 602, and the other end of the torsion spring 603 is connected to the wall-adhering arm 604; a wall-adhering wheel 6041 is rotatably mounted on the wall-adhering arm 604; the wall-adhering wheel 6041 is used for rolling the wall-adhering The infrared laser pre-judgment unit 7 comprises: an extension plate 701, a wall-side limiting plate 702 and an infrared laser lamp 703. The QY-620 infrared laser lamp 703 can be used. The extension plate 701 is fixedly mounted on the side of the wall-attached arm 604 by bolts; the wall-side limiting plate 702 is fixedly mounted on the extension plate 701; the wall-side limiting plate 702 is used to fit the side of the wall for limiting; the infrared laser lamp 703 is fixedly mounted on the wall-side limiting plate 702; the infrared laser lamp 703 irradiates the wall bulge through rays; the wall-attached wheel 6041 is used to limit the distance between the laser irradiated by the infrared laser lamp 703 and the wall surface, and the infrared laser pre-judgment unit 7 is used. Infrared rays can be used to reflect the flatness of the wall by using the standard straight line illuminated by its light. This structure can predict the flatness of the wall. When controlling the installation wheel frame 101 to move up for the bulge test, the flatness of the external wall can be more intuitively understood, and the height of the bulge on the external wall can be estimated and marked, which is convenient for subsequent rapid detection at the corresponding position. The infrared laser lamp 703 used in this structure irradiates the laser in the shape of a "one" shape, which can improve the comprehensiveness of irradiation and reduce the missed detection rate. The role of the wall-mounted wheel 6041 is to control the distance between the laser irradiated by the infrared laser lamp 703 and the external wall, which can avoid infrared laser The large distance between the light lamp 703 and the outer wall causes a large number of outer wall bulges to be missed. To reduce the missed detection rate and facilitate the staff to intuitively understand the bulge situation, the speed of pulling the installation wheel frame 101 can be appropriately increased in the non-bulge position to improve the detection efficiency. When this structure is used, the infrared laser lamp 703 is located on the side of the wall to be inspected, and the "I"-shaped light is parallel to the wall. The closer the rays of the infrared laser lamp 703 are to the outer wall, the higher the detection sensitivity for the outer wall bulge. As the installation wheel frame 101 moves, the infrared laser lamp 703 can be driven to move together to realize infrared ray detection, and the wall where there is a bulge will show laser rays.

[0039] The working principle of this embodiment is as follows: first, the rope of the winch can be connected through the traction frame 105, and the structure can be controlled by the external winch to move and rise outside the building to adjust the detection position. The structure can also be pulled up by manpower through the rope. First, the moving belt 104 is attached to the floor, and the suction pump 201 is started to generate suction force, and air is sucked through the suction box 202. At this time, the moving belt 104 can be negatively pressed against the outer wall of the building. As the installation wheel frame 101 is pulled up by the winch, the pulley 103 cooperates with the moving belt 104 to move on the surface of the outer wall of the building. As the pressing roller 304 rolls to the bulge, the lifting shaft 301 is pressed to slide outward, and the roller frame 303 will squeeze the micro switch 402. If the protrusion is large, the detection adapter tube 401 will cooperate with the retraction spring 4011 to elastically retract and adapt. At this time, the micro switch The switch 402 can control the upper alarm light 5011 to light up and alarm. At this time, the pressing detection electric push rod 102 can be started. The pressing detection electric push rod 102 pushes the roller frame 303 to drive the fitting pressing roller 304 to press the bulge on the wall. At this time, if the bulge is squeezed and retracted by the fitting pressing roller 304, the roller frame 303 will be separated from the microswitch 402, and the microswitch 402 will control the upper alarm light 5011 to go out, indicating that there is a safety hazard here and the wall skin needs to be removed for repair. If the bulge is not compressed by the fitting pressing roller 304, the roller frame 303 will not be separated from the microswitch 402, and the upper alarm light 5011 will be kept on to alarm, so that the staff can know that the current bulge is a normal bulge. The starting point for installing the wheel frame 101 starts from the edge of the building's exterior wall, as shown in the attached figure. Figure 3 The installation position shown, at this time, the wall side limit plate 702 is attached to the side of the external wall to be detected, and with the torque of the torsion spring 603, the wall-attaching wheel 6041 elastically adheres to the wall surface. At this time, the infrared laser light 703 is located on the side of the wall to be detected, and the "I"-shaped light irradiated is parallel to the wall. As the installation wheel frame 101 moves, the infrared laser light 703 can be driven to move together to realize infrared ray detection. During the process, the bulge can be predicted and recorded by means such as taking pictures;

[0040] When the laminating pressing roller 304 presses on the wall, the fallen wall skin is received by the anti-falling collecting box 501, and the wall falls into the anti-falling collecting box 501, and hits the pressing plate 503 under the action of gravity, thereby pressing the anti-falling micro switch 505, controlling the alarm light 5011 below to light up the alarm, and a row of V-shaped spring pieces 506 are used to elastically squeeze the pressing plate 503 to move up and reset.
