Description

Technical Field

[0001] The present invention relates to the technical field of wall verticality detection devices for engineering construction, in particular to a wall verticality detection device for engineering construction. Background Art

[0002] In the field of engineering and construction, wall verticality is a key indicator of construction quality. Whether the wall verticality meets the standard directly affects the stability and safety of the building structure and the smooth progress of subsequent decoration and renovation projects. If the wall verticality deviates significantly, it may lead to uneven stress on the wall, which may cause cracking and tilting after long-term use. In severe cases, it may even threaten the structural safety of the entire building. At the same time, uneven walls will greatly inconvenience subsequent door and window installation, wall decoration, and other tasks, increasing construction costs and difficulty.

[0003] Patent announcement number CN221223705U is a wall verticality detection device for engineering construction. The detection device controls the laser rangefinder through a linear module to lift and lower the wall to measure the wall, and uses a drive motor, a ball screw and a No. 1 slide to move the linear module, so as to facilitate the position movement of the laser rangefinder. After the device is placed and positioned, it can measure a large area of ​​the wall without the need to move the device frequently. However, the above-mentioned wall verticality detection device only supports the equipment through self-locking universal wheels, which has high requirements for the hardness and flatness of the ground. If the device is placed on a muddy ground with many potholes, the device itself cannot ensure that it is in an absolutely horizontal state, and the data detected by the device in a skewed state will be quite different from the data detected in a horizontal state, resulting in a large error in the verticality detected by the device.

[0014] The present invention provides a device for detecting the verticality of a wall surface for use in construction projects. It has the following beneficial effects: 1. The present invention is provided with a calibration device. Before the verticality detection of the wall is performed, the spirit level is used to detect whether the carrying base is in a horizontal state, and the height of the support legs is adjusted in conjunction with the limit spikes, the limit plates and the limit springs. When the equipment is moved to a relatively pothole-like place on the ground, the support legs are adjusted to the height of the support legs in conjunction with the universal wheels, so that the support legs can replace one set of universal wheels to support the carrying base, thereby avoiding the carrying base being not in a horizontal state due to uneven ground, which causes large errors in the data measured by the laser rangefinder, and solves the problem that it is difficult to measure accurate data when the bottom surface is uneven; after the height of the support legs is adjusted, the position of the support legs is fine-tuned in conjunction with the connecting rod, the support block, the fixing plate and the bolts, thereby avoiding the support legs being unable to fix the carrying base in a horizontal state due to the limited adjustable height, thereby causing large errors in the data measured by the laser rangefinder, and solves the problem that the adjustment range of the support legs is limited.

[0015] 2. The present invention is provided with a stabilizing device. When the supporting legs are unfolded downward, the supporting plates are rotated in cooperation with the hinge block, the positioning block, the return spring and the inclined plate. When unfolded, the angle between the supporting plates and the supporting legs is reduced, and the distance between the supporting plates and the ground is reduced, thereby preventing the supporting plates from being unable to contact the ground when the supporting legs support the carrying base, thereby causing the carrying base to be supported by only a single point of the supporting legs, resulting in unstable support, and solving the problem that the supporting legs cannot stably support the carrying base when the ground is relatively wet; when the supporting legs are retracted, the extrusion plate is cooperated to squeeze the elastic airbag, so that the elastic airbag blows air to the bottom surface of the supporting legs, thereby preventing the bottom surface of the supporting legs from sticking too tightly to debris such as soil, causing the supporting legs to be difficult to pull out after being poked into the soil, and solving the problem that the equipment is difficult to move and retract when it is moved to wet land.

[0016] 3. The present invention is provided with a protective device, and when the supporting legs are unfolded, the side plates, connecting plates, connecting springs and push plates are used to push the shielding plates to rotate, thereby shielding the soil around the supporting legs on the sides of the supporting legs, preventing rain from falling into the soil around the supporting legs when the wall is inspected, thereby causing the hardness of the soil to decrease and the supporting legs to sink further during inspection, solving the problem of errors caused by environmental influences during inspection; while the supporting legs are unfolded, the positioning columns, return springs and extrusion blocks are used to push the sliding blocks to repeatedly impact the connecting plates, causing the supporting legs to vibrate when they are unfolded downward or retracted upward, shaking off the wet soil stuck on their outer walls, thereby preventing the soil from sticking to the outer walls of the supporting legs and drying up, causing the shape of the supporting legs to change, solving the problem that the outer walls of the supporting legs may change due to the drying of the sticky soil, resulting in errors in the supporting effects of the supporting plates and the supporting legs.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 7 One embodiment of the present invention is: a wall verticality detection device for engineering construction, including a carrying base 1, a bracket 2 is fixed above the carrying base 1, a universal wheel 3 is fixed to the bottom surface of the carrying base 1, and a detection mechanism 4 is provided above the carrying base 1. The detection mechanism 4 includes a motor, a pulley, a threaded rod and a sliding rod. The motor is fixedly connected to the side wall of the bracket 2, and the pulley is fixedly connected to the output end of the motor. The equipment is parked at a place where inspection is required, and the motor is started. The motor drives the pulley to rotate. The threaded rod passes through the bracket 2 and is rotatably connected at the penetration point. The pulley is fixed on the end of the threaded rod away from the bracket 2. A belt is connected between the two sets of pulleys. The pulley fixedly connected to the output end of the motor transmits kinetic energy to the pulley fixedly connected to the threaded rod through the belt, thereby driving the threaded rod to rotate. The threaded rod passes through the sliding rod and is threaded at the penetration point. When the threaded rod rotates, it drives the sliding rod to move left and right. A laser rangefinder 5 slides on the side wall of the sliding rod. The sliding rod moves left and right, further driving the laser rangefinder 5 to move. The laser rangefinder 5 emits a laser and the reflected laser records the distance between the wall and the laser rangefinder 5. The side wall of the carrying base 1 is provided with a calibration device for calibrating the level of the carrying base 1.

[0021] Among them, the calibration device includes a spirit level 61, a connecting rod 62, a support block 63, a support leg 64, a fixing plate 65, a bolt 66, a limit spike 67, a limit plate 68 and a limit spring 69. The spirit level 61 is fixedly connected to the side wall of the carrying base 1. The spirit level 61 on the side wall of the carrying base 1 is used to check whether the carrying base 1 is in a horizontal state. The side wall of the carrying base 1 is fixed with a protrusion. The connecting rod 62 passes through the protrusion of the carrying base 1 and is slidably connected at the penetration point. The support block 63 is fixedly connected to both ends of the connecting rod 62. The support block 63 is slidably connected to the side wall of the protrusion of the carrying base 1. The support leg 64 passes through the support block 63 and is slidably connected at the penetration point. If the carrying base 1 is not in a horizontal state, the support legs are unfolded 64, provides third-party support for the carrying base 1, replaces the supporting force of the universal wheel 3 on the carrying base 1 near the support leg 64, the fixing plate 65 is fixedly connected to the upper surface of the support block 63, the bolt 66 passes through the fixing plate 65, and is threadedly connected at the penetration point. When the position of the support leg 64 needs to be adjusted, the bolt 66 is turned to release the limit on the position of the support leg 64, and the support block 63 is pushed. The support block 63 drives the connecting rod 62 to slide on the inner wall of the carrying base 1, so that the two groups of support blocks 63 drive the support legs 64 to move at the same time. When the support leg 64 is moved to the desired position, the bolt 66 is turned in the opposite direction to limit the support block 63 and the support leg 64. The limiting spike 67 is fixedly connected to both sides of the support leg 64 When the support leg 64 is in a horizontal position, the limit plate 68 is released, and the limit plate 68 is subjected to the elastic force of the limit spring 69 to restore and slide in the direction of the support leg 64, and is penetrated by the limit spike 67 again, and the limit spike 67 is stuck in the support leg 64. The limiting plate 68 limits the support legs 64 through the limiting spikes 67. Before the calibration device detects the verticality of the wall, it uses the level 61 to detect whether the carrier base 1 is in a horizontal state, and cooperates with the limiting spikes 67, the limiting plate 68 and the limiting spring 69 to adjust the height of the support legs 64. When the equipment is moved to a relatively pothole-like place on the ground, the support legs 64 are adjusted in height in cooperation with the universal wheels 3. The support legs 64 can replace one set of universal wheels 3 to support the carrier base 1, thereby avoiding the carrier base 1 being not in a horizontal state due to uneven ground, thereby preventing the data measured by the laser rangefinder 5 from having a large error. This solves the problem of difficulty in measuring accurate data when the bottom surface is uneven. After adjusting the height of the support leg 64, the position of the support leg 64 is fine-tuned in conjunction with the connecting rod 62, the support block 63, the fixing plate 65 and the bolt 66 to avoid the problem that the support leg 64 is unable to fix the carrying base 1 in a horizontal state due to the limited adjustable height, thereby causing the data measured by the laser rangefinder 5 to have a large error, thereby solving the problem of the limited adjustment range of the support leg 64.

[0022] When this embodiment is working: the equipment is parked at the place where inspection is required, the motor is started, the motor drives the pulley to rotate through the bearing, and the pulley fixedly connected to the output end of the motor transmits kinetic energy to the pulley fixedly connected to the threaded rod through the belt, thereby driving the threaded rod to rotate. When the threaded rod rotates, since the sliding rod is threadedly connected to it and the bottom surface of the sliding rod is in contact with the carrying base 1, the sliding rod cannot rotate. When the threaded rod rotates, it drives the sliding rod to move left and right, and further drives the laser rangefinder 5 to move. The laser rangefinder 5 emits laser and the reflected laser records the distance between the wall and the laser rangefinder 5.

[0023] When the equipment is parked at the place where it needs to be inspected, check whether the carrying base 1 is in a horizontal state by using the spirit level 61 on the side wall of the carrying base 1. If the carrying base 1 is not in a horizontal state, the supporting legs 64 are unfolded to provide third-party support for the carrying base 1, replacing the supporting force of the universal wheel 3 close to the supporting leg 64 on the carrying base 1. When the position of the supporting leg 64 needs to be adjusted, the bolt 66 is rotated to move the bolt 66 upward, away from the protrusion of the carrying base 1, to release the limit on the position of the supporting leg 64, and push the supporting block 63. The supporting block 63 drives the connecting rod 62 to slide on the inner wall of the carrying base 1, so that the two groups of supporting blocks 63 drive the supporting legs 64 to move at the same time. When the supporting legs 64 are moved to the desired position, the bolt 66 is rotated in the opposite direction. 66 moves downward and fits tightly with the protrusion of the carrying base 1, increasing the friction between the bolt 66 and the carrying base 1, thereby limiting the support block 63 and the support leg 64. When the height of the support leg 64 needs to be adjusted, the limit plate 68 is moved in the direction away from the support leg 64, so that the limit plate 68 disengages from the limit spike 67. When the limit plate 68 slides in the direction away from the support leg 64, it also compresses the limit spring 69 and pulls the support leg 64 downward. When the spirit level 61 shows that the carrying base 1 is in a horizontal state, the limit plate 68 is released. The limit plate 68 slides in the direction of the support leg 64 under the elastic force of the limit spring 69 and is penetrated by the limit spike 67 again. The limit spike 67 is stuck in the limit plate 68, so that the limit plate 68 limits the support leg 64 through the limit spike 67.

[0024] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a stabilizing device for further support is provided on the side of the calibration device, and the stabilizing device includes a hinge block 71, a support plate 72, a positioning block 73, a return spring 74, an extrusion plate 75, an elastic airbag 76 and an inclined plate 77. The hinge block 71 passes through the support leg 64 and is slidably connected at the penetration point. When the support leg 64 is unfolded downward, the support leg 64 drives the hinge block 71 to move downward. When the hinge block 71 moves downward, it also slides in the direction away from the carrying base 1. The bottom end of the support plate 72 is hinged to the front end of the hinge block 71. When the hinge block 71 slides in the direction away from the carrying base 1, it drives the support plate 72 and its hinge point forward. When the cam 72 is in the forward position, the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, and the cam 72 is in the forward position, so that the cam 72 is in the forward position, When the support leg 64 is retracted, the hinge block 71 is subjected to the elastic force of the return spring 74 to slide in the direction of the carrying base 1, and the extrusion plate 75 is slidably connected to the inner wall of the support leg 64, and the elastic airbag 76 is fixedly connected to the inner wall of the support leg 64. When the angle between the support plate 72 and the support leg 64 becomes larger, the extrusion plate 75 is pushed by the support plate 72 to slide toward the center of the support plate 72, and the air inlet and outlet of the elastic airbag 76 are connected to the bottom surface of the support leg 64. When the extrusion plate 75 slides, the elastic airbag 76 is squeezed, and the air in the elastic airbag 76 is pushed out, so that the elastic airbag 76 blows against the bottom surface of the support leg 64, removing the mud sticking to the bottom surface of the support leg 64. The inclined plate 77 is fixedly connected to the bottom surface of the support block 63 to blow off the dirt and other debris. The side of the hinge block 71 is slidably connected to the side of the inclined plate 77. When the support leg 64 is unfolded downward, the stabilizing device cooperates with the hinge block 71, the positioning block 73, the return spring 74 and the inclined plate 77 to rotate the support plate 72, thereby reducing the angle between the support plate 72 and the support leg 64 during the unfolding, reducing the distance between the support plate 72 and the ground, and preventing the support plate 72 from being unable to contact the ground when the support leg 64 supports the carrying base 1, thereby preventing the carrying base 1 from being supported by only a single point of the support leg 64, resulting in unstable support. This solves the problem that the support leg 64 cannot stably support the carrying base 1 when the ground is relatively wet. When the support leg 64 is retracted, the elastic airbag 76 is squeezed in conjunction with the extrusion plate 75, so that the elastic airbag 76 blows air to the bottom surface of the support leg 64, thereby preventing the bottom surface of the support leg 64 from sticking too tightly to the soil and other debris, causing the support leg 64 to be difficult to pull out after being poked into the soil, thereby solving the problem of difficulty in moving and retracting the equipment when it is moved to wet land.

[0025] A protective device is provided on the side of the calibration device to prevent the bottom from deforming. The protective device includes a side plate 81, a connecting plate 82, a connecting spring 83, a push plate 84, a shield 85, a positioning column 86, a return spring 87, a sliding block 88 and an extrusion block 89. The side plate 81 is fixedly connected to the upper surface of the support block 63, and the connecting plate 82 is fixedly connected to the upper surface of the support leg 64. When the support leg 64 moves downward and unfolds, the support leg 64 drives the connecting plate 82 to slide downward. The connecting spring 83 is fixedly connected to the bottom surface of the connecting plate 82. The connecting plate 82 slides downward, driving the connecting spring 83 to move downward as well. The push plate 84 is fixed When the push plate 84 slides to the shield plate 85, the shield plate 85 is pushed to rotate around the hinge between it and the support block 63, blocking the side of the support leg 64. The positioning column 86 is fixedly connected to the side wall of the connecting plate 82. When the connecting plate 82 slides downward, it also drives the positioning column 86 to move downward. A circular plate is fixed on the end of the positioning column 86 away from the connecting plate 82, and a return spring 87 is formed on the side wall of the support block 63. The end is fixedly connected to the side wall of the circular plate, the positioning column 86 passes through the sliding block 88, and is slidably connected at the penetration point. The positioning column 86 drives the return spring 87 and the sliding block 88 to move downward. The other end of the return spring 87 is fixedly connected to the side wall of the sliding block 88, and the extrusion block 89 is fixedly connected to the side wall of the side plate 81. When the sliding block 88 moves to the extrusion block 89, the extrusion block 89 pushes the sliding block 88 to slide in the direction away from the connecting plate 82, and at the same time compresses the return spring 87. When the connecting plate 82 drives the sliding block 88 to continue to slide downward until it is separated from the extrusion block 89, the sliding block 88 is reset by the return spring 87. The original elastic force slides in the direction of the connecting plate 82, impacting the connecting plate 82, causing the connecting plate 82 to drive the supporting leg 64 to shake. When the supporting leg 64 is unfolded, the protective device cooperates with the side plate 81, the connecting plate 82, the connecting spring 83 and the push plate 84 to push the shield plate 85 to rotate, shielding the ground around the supporting leg 64 on the side of the supporting leg 64, thereby preventing rain from falling into the ground around the supporting leg 64 during the wall inspection, thereby reducing the hardness of the soil and causing the supporting leg 64 to sink further during the inspection, thereby solving the problem of errors caused by environmental influences during the inspection. When the support legs 64 are unfolded, the positioning column 86, return spring 87 and extrusion block 89 push the sliding block 88 to repeatedly impact the connecting plate 82, so that the support legs 64 vibrate when they are unfolded downward or retracted upward, shaking off the wet mud sticking to their outer walls, thereby preventing the mud from sticking to the outer walls of the support legs 64 and drying up, causing the shape of the support legs 64 to change. This solves the problem that the outer walls of the support legs 64 may change due to the drying of the sticky mud, resulting in an error in the supporting effect of the support plate 72 and the support legs 64.

[0026] When the support leg 64 is extended downward, the support leg 64 drives the hinge block 71 to move downward, and the hinge block 71 and the side wall of the inclined plate 77 slide against each other, and the inclination of the inclined plate 77 is small. Therefore, when the hinge block 71 moves downward, it is also squeezed by the inclined plate 77 to slide in the direction away from the carrying base 1. When the hinge block 71 slides in the direction away from the carrying base 1, it drives the support plate 72 and its hinge point to move forward, and at the same time stretches the return spring 74. The support plate 72 is penetrated by the positioning block 73 and remains in the horizontal position. Therefore, when the hinge point of the support plate 72 and the hinge block 71 moves forward, the support plate 72 itself also rotates, so that the angle between the support plate 72 and the support leg 64 becomes smaller. When the angle between the support plate 72 and the support leg 64 becomes smaller, it is more convenient to contact the ground. The support plate 72, the ground and the support leg 64 form a triangle, which makes the support of the support leg 64 to the carrying base 1 more stable. When the support leg 64 is folded, the hinge block 71 is no longer squeezed by the inclined plate 77, and at the same time is restored by the elastic force of the return spring 74, and slides toward the direction of the carrying base 1. The hinge block 71 drives the support plate 72 to rotate, and the angle between the support plate 72 and the support leg 64 becomes larger. When the support plate 72 rotates to its top and contacts the extrusion plate 75, the extrusion plate 75 is pushed toward the center of the support plate 72 by the push of the support plate 72. When the extrusion plate 75 slides, it squeezes the elastic airbag 76, pushes out the air in the elastic airbag 76, and causes the elastic airbag 76 to blow air to the bottom surface of the support leg 64.

[0027] When the support leg 64 moves downward and unfolds, the support leg 64 drives the connecting plate 82 to slide downward, and the connecting plate 82 slides downward, driving the connecting spring 83 to move downward as well, and the connecting spring 83 pushes the push plate 84 to slide downward. When the push plate 84 slides to the shield plate 85, the shield plate 85 is pushed to rotate around the hinge between it and the support block 63. When the push plate 84 slides to the bottom, the upper surface of the shield plate 85 fits with the bottom surface of the push plate 84, blocking the side of the support leg 64. When the connecting plate 82 slides downward, it also drives the positioning column 86 to move downward, and the positioning column 86 is fixed. The positioning column 86 drives the return spring 87 and the sliding block 88 to move downward. When the sliding block 88 moves to the extrusion block 89, its oblique side and the oblique surface of the extrusion block 89 slide against each other, and the extrusion block 89 pushes the sliding block 88 to slide away from the connecting plate 82, while compressing the return spring 87. When the connecting plate 82 drives the sliding block 88 to continue to slide downward until it is separated from the extrusion block 89, the sliding block 88 is subjected to the elastic force of the return spring 87 to slide toward the connecting plate 82, hitting the connecting plate 82, causing the connecting plate 82 to drive the supporting leg 64 to shake.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
