Description

Technical Field

[0001] This invention relates to the technical field of mechanical engineering, and in particular to a walkable device and method for detecting the dimensions of building walls. Background Technology

[0002] In recent years, walkable building wall dimension inspection devices have made significant technological progress and are increasingly widely used in the construction industry. With the continuous advancement of sensor technology, the accuracy of devices such as visual inspection heads and flatness inspection sensors has been greatly improved. For example, laser scanners can achieve millimeter-level resolution and can capture tiny defects on the wall surface. In order to improve the stability and adaptability of the adhesion, many inspection devices adopt a multi-point negative pressure adsorption mechanism, which makes the walking wheels firmly adsorbed on the wall and drives the device to climb the wall to perform dimension inspection.

[0003] Some existing portable building wall dimension measuring devices typically rely solely on a single negative pressure adsorption mechanism. When the negative pressure system fails due to insufficient air pressure, uneven wall surfaces, or obstacles, the device may suddenly fall from a height, causing serious injury to workers below. Furthermore, the complex environment of construction sites means that the negative pressure adsorption mechanism may also draw dust from the wall surface into the device during the suction process, contaminating internal mechanical and electronic components and leading to equipment malfunction. Although some negative pressure adsorption mechanisms are equipped with dust filters, these filters are still prone to clogging. Clogged filters impede airflow, potentially reducing the adsorption efficiency of the negative pressure system. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned walkable building wall size detection devices, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a walkable building wall dimension detection device.

[0010] As a preferred embodiment of the walkable building wall dimension detection device of the present invention, wherein: a plurality of negative pressure suction pipes are alternately distributed along the inner surfaces of the walking wheels on both sides; the inner wall of the drive shaft is in rotatable contact with the outer surface of the suction pipe; the outer end face of the negative pressure suction pipe is in sliding contact with the outer surface of the suction pipe; and the negative pressure suction pipe, the visual inspection head, and the flatness detection sensor are all electrically connected to the drive component.

[0011] As a preferred embodiment of the walkable building wall dimension detection device of the present invention, the transmission component includes a first bevel gear fixedly sleeved on the outer surface of the drive shaft, a second bevel gear meshing with the outer surface of the first bevel gear, a drive column fixedly connected to the inner surface of the second bevel gear, a first belt disc fixedly sleeved on the outer surface of the drive column, a belt sleeved on the outer surface of the first belt disc, a second belt disc sleeved on the inner surface of the other end of the belt, and a driven column fixedly connected to the inner surface of the second belt disc.

[0012] In a preferred embodiment of the walkable building wall dimension detection device of the present invention, the outer surfaces of the driving column and the driven column are in rotatable contact with the outer surface of the driving member, and the connection between the driving column and the driven column and the driving member is equipped with a rotating bearing sleeve.

[0013] As a preferred embodiment of the walkable building wall dimension detection device of the present invention, the adsorption component includes a reciprocating roller fixedly connected to the outer end face of the driven column, a sleeve slidably sleeved on the outer surface of the reciprocating roller, a fixing rod fixedly connected to the outer surface of the sleeve via a connecting rod, and a connecting block fixedly connected to the outer end face of the fixing rod.

[0014] As a preferred embodiment of the walkable building wall size detection device of the present invention, the adsorption assembly further includes a suction cup hinged to the inner wall of the connecting block, and a limiting block fixedly connected to the outer surface of the driving component and used in conjunction with the fixing rod.

[0015] As a preferred embodiment of the walkable building wall dimension detection device of the present invention, the fixing rod, connecting block and suction cup are alternately distributed on both sides of the fixing frame, and the inner surface of the fixing rod slides in contact with the outer surface of the limiting block.

[0017] The present invention also provides a processing method.

[0018] This invention provides the following technical solution: a method of use, including the aforementioned walkable building wall dimension detection device, the method comprising the following steps:

[0019] S1: Calibrate the visual inspection head and flatness detection sensor to ensure they can accurately capture information about the wall surface, and check the vents to ensure unobstructed airflow;

[0020] S2: Place the walking wheel on the wall surface, so that the negative pressure suction pipe on the inner surface of one of the walking wheels is perpendicular to the wall and connected to the suction pipe. Turn on the drive to drive the suction pipe to suck in air and form a negative pressure area in the negative pressure suction pipe.

[0021] S3: The drive shaft and the walking wheel rotate synchronously through the drive component, so that the walking wheel drives the device to move along the wall surface. The continuous rotation of the walking wheel drives the negative pressure suction pipe on its inner surface to rotate accordingly, ensuring that it can effectively contact the wall in multiple positions.

[0022] S4: When the negative pressure suction tube is rotated to the position where it is no longer in contact with the wall, the suction cup will move synchronously to the position where it contacts the wall and adhere to the wall surface. Through the cooperation of the fixing rod and the connecting block, it can prevent the fixing rod from breaking due to the continuous movement of the device when the suction cup is adhered to the wall surface.

[0023] S5: When the airflow is drawn into the negative pressure intake pipe, it squeezes the impeller, causing the impeller to rotate. Then, through the cooperation between the impeller and the support shaft, it drives the scraper to rotate, so that the scraper can sweep away the dust attached to the surface of the filter screen.

[0024] The beneficial effects of this invention are as follows: Through the cooperation between the various components in the walking mechanism, a stable negative pressure area can be formed inside the negative pressure suction pipe during the movement of the walking wheels. The detection component can accurately detect minor defects and overall flatness of the wall surface. The adsorption component can cause the suction cup to adhere to the wall surface when the negative pressure suction pipe is detached from the wall surface, and move the suction cup to a position where it is detached from the wall surface when the negative pressure suction pipe is in contact with the wall surface, thus avoiding affecting the normal movement of the device. This allows the device to remain firmly attached to the wall even if the negative pressure suction pipe fails or the wall surface is abnormal. The cleaning component can automatically remove dust and impurities from the filter screen surface when the airflow enters the negative pressure suction pipe, ensuring that the negative pressure suction pipe can continuously and effectively draw in air.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0038] Example 1

[0039] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6The first embodiment of the present invention provides a walkable building wall dimension detection device. The device includes a walking mechanism 100, including a fixed frame 101, a plurality of driving components 102 respectively adapted to be installed on the bottom of both sides of the fixed frame 101, a driving shaft 103 fixedly installed on the output end of the driving component 102 via a coupling, a walking wheel 104 fixedly sleeved on the outer surface of the driving shaft 103, an air extraction pipe 105 fixedly connected to the inner surface of the driving component 102 and communicating with the inner cavity of the walking wheel 104, a plurality of negative pressure suction pipes 106 arranged in a circumferential array on the outer surface of the walking wheel 104, an air outlet 107 fixedly installed on the inner surface of the fixed frame 101 and used in conjunction with the air extraction pipe 105, and a detection component 108 used in conjunction with detecting the wall surface.

[0040] It should be noted that the fixed frame 101 is the basic frame of the entire walking mechanism 100, used to support and fix all other components. When the driving component 102 drives the driving shaft 103 to rotate synchronously with the walking wheel 104, the device moves along the wall surface. When the walking wheel 104 rotates, it can drive the negative pressure suction pipe 106 on its inner surface to rotate accordingly. These negative pressure suction pipes 106, which are arranged in a circumferential array and staggered on the inner surface of the walking wheels 104 on both sides, can ensure that they can effectively contact the wall in multiple positions. When the negative pressure suction pipe 106 is in a position perpendicular to the wall surface, it can be connected to the suction pipe 105. When the negative pressure suction pipe 106 is connected to the suction pipe 105, the air is quickly drawn out by the suction pipe 105 to form a negative pressure area, thereby preventing the device from falling off. The air outlet 107 is used to maintain airflow circulation and ensure the normal operation of the negative pressure system.

[0041] The fall protection mechanism 200 includes a transmission component 201 for transmitting power to the drive component 102, an adsorption component 202 for assisting adsorption when the negative pressure suction pipe 106 is out of contact with the wall, a filter screen 203 threaded to the inner wall of the negative pressure suction pipe 106, and a cleaning component 204 for preventing the filter screen 203 from being clogged by dust.

[0042] It should be noted that the filter screen 203 can prevent dust and impurities on the wall surface from being sucked into the device through the negative pressure suction pipe 106. The cleaning component 204 can use the airflow force when the suction pipe 105 sucks in air to remove the dust on the surface of the filter screen 203, thereby avoiding the situation where the suction pipe 105 cannot effectively suck in air because the filter screen 203 is blocked by dust.

[0043] Specifically, the detection component 108 includes a visual inspection head 108a adapted to be installed on the outside of the fixture 101, a flatness detection sensor 108b adapted to be installed below the visual inspection head 108a, and a wiring conduit 108c fixedly connected to the inner surface of the fixture 101.

[0044] Furthermore, the visual inspection head 108a captures images of the wall surface using a high-resolution laser scanner, thereby identifying cracks, protrusions, depressions, and other obstacles that may affect the robot's movement. The collected image data is transmitted in real-time to a remote terminal via the internet, helping staff plan the device's path in advance to avoid potentially dangerous areas. The flatness detection sensor 108b accurately senses minute unevenness in the wall, such as tilting, ripples, or localized deformation, using an optical sensor, and feeds the data back to the remote terminal in real-time via the internet. This allows staff to adjust the suction strength of the extraction pipe 105 based on this information, ensuring the device maintains good contact with the wall at all times. The wiring conduit 108c not only protects and manages the connecting cables of various sensors and electronic components but also ensures that the sensor data lines are neatly connected to the control system interface, thus guaranteeing the stability and reliability of signal transmission.

[0045] During use, calibrate the visual inspection head 108a and the flatness detection sensor 108b to ensure they can accurately capture information about the wall surface. Check the vent 107 to ensure unobstructed airflow. Place the walking wheels 104 on the wall surface, ensuring that the negative pressure suction pipe 106 on the inner surface of one of the walking wheels 104 is perpendicular to the wall and connected to the suction pipe 105. Turn on the drive unit 102 to drive the suction pipe 105 to draw in air, causing air to be quickly drawn out by the suction pipe 105 and into the negative pressure suction pipe 108b. A negative pressure zone is formed inside the device to prevent it from falling off. At the same time, the drive shaft 103 and the walking wheel 104 are rotated synchronously by the drive component 102, so that the walking wheel 104 moves the device along the wall surface. The continuous rotation of the walking wheel 104 drives the negative pressure suction pipe 106 on its inner surface to rotate accordingly. These negative pressure suction pipes 106, which are arranged in a circumferential array and staggered on the inner surface of the walking wheel 104 on both sides, can ensure that they can effectively contact the wall at multiple positions to achieve the effect of preventing the device from falling off.

[0046] In summary, through the cooperation between the various components in the walking mechanism 100, a stable negative pressure area can be formed inside the negative pressure suction pipe 106 during the movement of the walking wheel 104, ensuring that the device is firmly attached to the wall to prevent the device from falling off. The detection component 108 can accurately detect the minute defects on the wall surface and the overall flatness to ensure the high accuracy of the detection results.

[0047] Example 2

[0048] Reference Figures 2-7This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that this embodiment provides a transmission component 201 for transmitting the power of the driving component 102, an adsorption component 202 that can use the power of the driving component 102 to drive the two sets of suction cups 202e to perform stepping movements, a filter screen 203 for preventing dust from being sucked into the device, and a cleaning component 204 that can use the airflow power when the suction pipe 105 sucks in the dust to sweep away the dust on the surface of the filter screen 203.

[0049] Furthermore, the transmission assembly 201 includes a first bevel gear 201a fixedly sleeved on the outer surface of the drive shaft 103, a second bevel gear 201b meshing with the outer surface of the first bevel gear 201a, a drive column 201c fixedly connected to the inner surface of the second bevel gear 201b, a first pulley 201d fixedly sleeved on the outer surface of the drive column 201c, a belt 201e sleeved on the outer surface of the first pulley 201d, a second pulley 201f sleeved on the inner surface of the other end of the belt 201e, and a driven column 201g fixedly connected to the inner surface of the second pulley 201f.

[0050] It should be explained that when the drive shaft 103 rotates, it can also drive the first bevel gear 201a to rotate synchronously, so that the first bevel gear 201a drives the second bevel gear 201b and the drive column 201c to rotate synchronously. Through the cooperation of the drive column 201c, the first belt disc 201d and the belt 201e, the second belt disc 201f and the driven column 201g are driven to rotate.

[0051] The outer surfaces of the drive column 201c and the driven column 201g are in rotatable contact with the outer surface of the drive member 102, and the connection between the drive column 201c and the driven column 201g and the drive member 102 is equipped with a rotating bearing sleeve.

[0052] Preferably, the adsorption assembly 202 includes a reciprocating roller 202a fixedly connected to the outer end face of the driven column 201g, a sleeve 202b slidably sleeved on the outer surface of the reciprocating roller 202a, a fixing rod 202c fixedly connected to the outer surface of the sleeve 202b via a connecting rod, and a connecting block 202d fixedly connected to the outer end face of the fixing rod 202c.

[0053] It should be noted that the adsorption assembly 202 also includes a suction cup 202e hinged to the inner wall of the connecting block 202d, and a limiting block 202f fixedly connected to the outer surface of the drive member 102 and used in conjunction with the fixing rod 202c.

[0054] It should be explained that when the driven column 201g rotates, it can drive the reciprocating roller 202a to rotate synchronously. The limiting block 202f limits the fixed rod 202c and the sleeve 202b, so that the sleeve 202b can move back and forth linearly through the rotation of the reciprocating roller 202a. This causes the sleeve 202b to drive the fixed rod 202c, the connecting block 202d and the suction cup 202e to move back and forth linearly.

[0055] Furthermore, the fixing rod 202c, the connecting block 202d, and the suction cup 202e are alternately distributed on both sides of the fixing frame 101, and the inner surface of the fixing rod 202c slides in contact with the outer surface of the limiting block 202f.

[0056] Furthermore, when the negative pressure suction pipe 106 rotates to a position where it is no longer in contact with the wall, the suction cup 202e will move synchronously to a position where it contacts the wall and adheres to the wall surface. Through the cooperation of the fixing rod 202c and the connecting block 202d, it is possible to prevent the fixing rod 202c from breaking due to the continuous movement of the device when the suction cup 202e is adhered to the wall surface.

[0057] Furthermore, the cleaning assembly 204 includes a support rod 204a fixedly connected to the inner wall of the negative pressure suction pipe 106, a support shaft 204b fixedly mounted on the outer surface of the support rod 204a via a bearing, an impeller 204c fixedly sleeved on the outer surface of the cleaning assembly 204, and a scraper 204d fixedly mounted on the outer end face of the impeller 204c and used in conjunction with the filter screen 203.

[0058] When the airflow is drawn into the negative pressure suction pipe 106, it can compress the impeller 204c, causing the impeller 204c to rotate. Then, through the cooperation between the impeller 204c and the support shaft 204b, the scraper 204d is driven to rotate, so that the scraper 204d removes the dust attached to the surface of the filter screen 203.

[0059] In use, the drive shaft 103 drives the first bevel gear 201a to rotate synchronously, which in turn drives the second bevel gear 201b and the drive column 201c to rotate synchronously. Through the cooperation of the drive column 201c, the first pulley 201d, and the belt 201e, the second pulley 201f and the driven column 201g rotate. The rotation of the driven column 201g then drives the reciprocating roller 202a to rotate synchronously. The limiting block 202f limits the fixed rod 202c and the sleeve 202b, causing the sleeve 202b to reciprocate linearly through the rotation of the reciprocating roller 202a. This, in turn, causes the sleeve 202b to drive the fixed rod 202c, the connecting block 202d, and the suction cup 202e to reciprocate linearly. When the suction pipe 106 rotates to the position where it is no longer in contact with the wall, the suction cup 202e will move synchronously to the position where it contacts the wall and adhere to the wall surface. Through the cooperation of the fixing rod 202c and the connecting block 202d, the fixing rod 202c can be prevented from breaking due to the continuous movement of the device when the suction cup 202e is adhered to the wall surface. When the airflow is drawn into the negative pressure suction pipe 106, it can squeeze the impeller 204c, causing the impeller 204c to rotate. Then, through the cooperation of the impeller 204c and the support shaft 204b, the scraper 204d is driven to rotate, so that the scraper 204d sweeps away the dust attached to the surface of the filter screen 203, thereby ensuring that the negative pressure suction pipe 106 can continuously and effectively draw in air.

[0060] In summary, the adsorption component 202 enables the suction cup 202e to adhere to the wall when the negative pressure suction pipe 106 is detached from the wall, and to move the suction cup 202e to a position where it is detached from the wall when the negative pressure suction pipe 106 is in contact with the wall, thus avoiding affecting the normal movement of the device. This ensures that the device can still be firmly attached to the wall even if the negative pressure suction pipe 106 fails or the wall surface is abnormal, thereby further reducing the risk of the device falling. The cleaning component 204 automatically removes dust and impurities from the surface of the filter screen 203 when the airflow enters the negative pressure suction pipe 106, ensuring that the negative pressure suction pipe 106 can continuously and effectively draw in air, thereby maintaining the stability of the negative pressure area.

[0061] Example 3

[0062] Reference Figures 1-7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a method of use, including a walkable building wall dimension detection device.

[0063] S1: Calibrate the visual inspection head 108a and the flatness detection sensor 108b to ensure that they can accurately capture information about the wall surface, and check the vent 107 to ensure that the airflow is unobstructed.

[0064] S2: Place the walking wheel 104 on the wall surface, so that the negative pressure suction pipe 106 on the inner surface of one of the walking wheels 104 is perpendicular to the wall and connected to the suction pipe 105. Turn on the drive unit 102 to drive the suction pipe 105 to suck air and form a negative pressure area in the negative pressure suction pipe 106.

[0065] S3: The drive shaft 103 and the walking wheel 104 are driven to rotate synchronously by the drive component 102, so that the walking wheel 104 drives the device to move along the wall surface. The continuous rotation of the walking wheel 104 drives the negative pressure suction pipe 106 on its inner surface to rotate accordingly, ensuring that it can effectively contact the wall in multiple positions.

[0066] S4: When the negative pressure suction tube 106 rotates to the position where it is no longer in contact with the wall, the suction cup 202e will move synchronously to the position where it contacts the wall and adhere to the wall surface. Through the cooperation of the fixing rod 202c and the connecting block 202d, it can prevent the fixing rod 202c from breaking due to the continuous movement of the device when the suction cup 202e is adhered to the wall surface.

[0067] S5: When the airflow is drawn into the negative pressure suction pipe 106, it squeezes the impeller 204c, causing the impeller 204c to rotate. Then, through the cooperation between the impeller 204c and the support shaft 204b, the scraper 204d is driven to rotate, so that the scraper 204d removes the dust attached to the surface of the filter screen 203.

[0068] In summary, through the cooperation between the components in the walking mechanism 100, this invention can create a stable negative pressure area inside the negative pressure suction pipe 106 during the movement of the walking wheel 104. The detection component 108 can accurately detect minor defects and overall flatness of the wall surface. The adsorption component 202 can cause the suction cup 202e to adhere to the wall surface when the negative pressure suction pipe 106 is detached from the wall surface, and when the negative pressure suction pipe 106 is in contact with the wall surface, the suction cup 202e can move to a position where it is detached from the wall surface, avoiding affecting the normal movement of the device. This ensures that the device can still firmly adhere to the wall even if the negative pressure suction pipe 106 fails or the wall surface is abnormal. The cleaning component 204 can automatically remove dust and impurities from the surface of the filter screen 203 when the airflow enters the negative pressure suction pipe 106, ensuring that the negative pressure suction pipe 106 can continuously and effectively draw in air.

6. A method of use, characterized in that: The method of the walkable building wall dimension detection device according to any one of claims 1 to 5 includes the following steps: S1: Calibrate the visual inspection head and flatness detection sensor to ensure they can accurately capture information about the wall surface, and check the vents to ensure unobstructed airflow; S2: Place the walking wheel on the wall surface, so that the negative pressure suction pipe on the inner surface of one of the walking wheels is perpendicular to the wall and connected to the suction pipe. Turn on the drive to drive the suction pipe to suck in air and form a negative pressure area in the negative pressure suction pipe. S3: The drive shaft and the walking wheel rotate synchronously through the drive component, so that the walking wheel drives the device to move along the wall surface. The continuous rotation of the walking wheel drives the negative pressure suction pipe on its inner surface to rotate accordingly, ensuring that it can effectively contact the wall in multiple positions. S4: When the negative pressure suction tube is rotated to the position where it is no longer in contact with the wall, the suction cup will move synchronously to the position where it contacts the wall and adhere to the wall surface. Through the cooperation of the fixing rod and the connecting block, it can prevent the fixing rod from breaking due to the continuous movement of the device when the suction cup is adhered to the wall surface. S5: When the airflow is drawn into the negative pressure intake pipe, it squeezes the impeller, causing the impeller to rotate. Then, through the cooperation between the impeller and the support shaft, it drives the scraper to rotate, so that the scraper can sweep away the dust attached to the surface of the filter screen.
