Description

Technical Field

[0001] The present invention relates to the technical field of wall detection, in particular to a wall detection device for architectural design. Background Art

[0002] The flatness of building walls is a key indicator that affects the safety, decorative aesthetics and usability of building structures. Especially in the construction of complex wall surfaces such as prefabricated buildings, curved curtain walls, and arched structures, high-precision measurements must be achieved through special detection equipment.

[0003] The existing wall detection devices mainly have the following technical defects: First, the existing devices mostly use a rigidly connected single-wheel or double-wheel structure, which can only fit flat walls. When there are irregular curved bumps on the wall surface, the detection wheel is prone to "point contact" or "local slip", resulting in the arc area cannot be effectively covered, thereby increasing the detection blind spot error. Secondly, the existing pressure detection is mostly integrated into the central fixed frame, and the detection wheels on both sides indirectly transmit pressure through mechanical connecting rods. When one side of the wall is raised, the connecting rod gap and rotational friction will cause the pressure signal to attenuate. Therefore, it is difficult to distinguish the difference between the pressure of the center wheel and the pressure of the wheels on both sides, creating a risk of misjudgment. In addition, the existing wall detection device with elastic effect cannot automatically reset the detection wheel when the curvature of the wall surface changes by more than 5°, and manual calibration is required, which reduces the detection efficiency.

DETAILED DESCRIPTION

[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] Example 1:

[0021] See also Figures 1 to 11 The present invention provides a technical solution: a wall detection device for architectural design, comprising a detection main frame 1, an operating shell 2 fixedly mounted on one side of the detection main frame 1, a first motor 3 and a second motor 4 symmetrically mounted on the bottom upper surface of the detection main frame 1, the output shafts of the first motor 3 and the second motor 4 fixedly connected to a lifting mechanism, and the lifting mechanism vertically slides on one side of the detection main frame 1, the architectural design wall detection device also comprising a pressure gauge 22 and three contact wheels 20 arranged in an arc shape to form an overall contact surface; A detection frame 11 is fixedly connected to one side surface of the lifting mechanism, so that the detection frame 11 can be lifted up and down, and the detection frame 11 drives the contact wheel 20 to move up and down for wall flatness detection; The transverse movement mechanism is fixedly mounted on the upper surface of the detection frame 11 to drive the contact wheel 20 to move horizontally. By linkage with the lifting mechanism, the wall can be inspected in multiple areas. The pressure adjustment mechanism is fixedly mounted on the upper surface of the transverse movement mechanism, so that when performing vertical and horizontal movement detection, the contact wheel 20 performs elastic self-adjustment of the curvature of the wall by contact, and feeds back the pressure elasticity to the pressure gauge 22; The auxiliary deformation mechanism is symmetrically connected to the contact wheels 20 on both sides, so that the angle of the contact wheel 20 changes synchronously with the change of the arc of the contact. Through the elastic deformation and arc adaptation of the center and the contact wheels 20 on both sides, the comprehensive pressure of the contact wheel 20 on the wall is transmitted to the pressure gauge 22.

[0022] More specifically, in this embodiment, the overall structure linkage detection process is as follows: 1. Equipment startup and initial positioning: Detection parameters including wall height and detection accuracy level are input through the operating housing 2 on one side of the detection main frame 1. The first motor 3 and the second motor 4 are started, driving the lifting mechanism to lower the detection frame 11. The three arc-shaped contact wheels 20 contact the bottom reference surface of the wall with initial pressure. The pressure gauge 22 is zeroed and calibrated to ensure that the initial pressure signal has no offset. 2. Multi-dimensional detection with linkage between lifting and lateral movement: The first motor 3 and the second motor 4 synchronously drive the lifting mechanism and the detection frame 11 for stable lifting and lowering motion. Subsequently, the lateral movement mechanism is driven to move horizontally on the detection frame 11. This achieves multi-dimensional detection through the linkage between lifting and lateral movement of the wall detection device, thereby covering the entire wall area. 3. Adaptive detection of irregular surfaces: The central contact wheel 20 contacts the center point surface of the irregular curved protrusion on the wall, providing central support. At the same time, the pressure adjustment mechanism first displays the pressure on the pressure gauge 22 in real time when the central contact wheel 20 contacts the wall surface. The contact wheels 20 on both sides, through the cooperation of the pressure adjustment mechanism and the auxiliary deformation mechanism, elastically contact the edge surfaces of the irregular curved protrusion on the wall. At the same time, the auxiliary deformation mechanism applies the pressure of the curved surfaces on both sides to the pressure adjustment mechanism, and the pressure adjustment mechanism integrates the pressure of the center and both sides and uniformly displays the pressure on the pressure gauge 22.

[0023] Furthermore, the lifting mechanism includes: The vertical screw rods 6 are arranged in groups of two and are symmetrically distributed. The vertical screw rods 6 are respectively fixedly connected to the output ends of the first motor 3 and the second motor 4. The threaded surfaces of the vertical screw rods 6 are threadedly sleeved with lifting sleeves 7. The lifting sleeves 7 are fixedly connected to one side surface of the detection frame plate 11. A synchronization rod 10 is fixedly connected between the lifting sleeves 7. The connection surface of the lifting sleeve 7 close to the detection frame plate 11 is symmetrically fixed with a special-shaped slider 9, and the vertical surface of one side of the detection main frame 1 is symmetrically provided with two groups of special-shaped slide grooves 8, and the special-shaped slider 9 is slidably connected to the inside of the special-shaped slide groove 8.

[0024] The operation process of the lifting mechanism is as follows: The first motor 3 and the second motor 4 rotate by driving two symmetrical vertical screws 6, and the lifting sleeve 7 is rigidly connected by a synchronization rod 10, eliminating the lifting and lowering synchronization caused by the difference in the thread gap of the vertical screws 6 on both sides. The thread rotation of the vertical screws 6 drives the lifting sleeve 7 to move up and down. At the same time, since the special-shaped sliders 9 on both sides of the lifting sleeve 7 are embedded in the special-shaped slide grooves 8 of the detection main frame 1, a guide structure for vertical lifting is formed, thereby avoiding the lifting and lowering deviation of the lifting sleeve 7 and the detection frame plate 11, and allowing the lifting sleeve 7 and the detection frame plate 11 to achieve a stable lifting movement. Among them, the special-shaped slider 9 is made of polytetrafluoroethylene, which can ensure that there is no jamming during the lifting process.

[0025] At this point, the combination of twin screws + synchronous rods + special-shaped guides reduces the verticality error of the detection frame 11 during lifting and lowering, and avoids "spiral deflection" caused by unilateral force.

[0026] Next, the traverse mechanism includes: The third motor 12 is fixedly mounted on the detection frame 11. A limit frame 13 is symmetrically fixedly mounted on the upper surface of the detection frame 11 near the third motor 12. The output end of the third motor 12 is fixedly connected to a transverse screw 14. Both ends of the transverse screw 14 are rotationally connected to the limit frame 13 through bearings. A transverse sleeve 15 is threadedly sleeved on the threaded surface of the transverse screw 14. A slide rail 16 is fixedly mounted on the upper surface of the detection frame 11 away from the third motor 12 , and a sliding frame 17 is slidably connected to the slide rail 16 . The transverse sleeve 15 is fixedly connected to the sliding frame 17 .

[0027] It is worth mentioning that the operation process of the transverse mechanism is as follows: Each time the lifting mechanism is lifted or lowered, the third motor 12 is started. The third motor 12 drives the transverse screw 14 to rotate through the coupling. The transverse sleeve 15 cooperates with the transverse screw 14 to provide a transverse driving force. The sliding frame 17 slides on the slide rail 16. The cross-section of the slide rail is "T"-shaped. The rotation of the transverse screw 14 drives the transverse sleeve 15 to provide a transverse driving force. At the same time, the transverse sleeve 15 drives the sliding frame 17 on the slide rail 16 to limit the horizontal displacement, so that the sliding frame 17 and the transverse sleeve 15 provide a transverse driving force for wall detection.

[0028] At this point, the double-track guide reduces the speed fluctuation of the transverse sleeve 15 within the stroke, avoiding the "creeping phenomenon".

[0029] Subsequently, the pressure adjustment mechanism includes: The cavity shell 21 is fixedly mounted on the upper surface of the transverse sleeve 15. A pressure-adjusting rod 23 is provided on one side of the cavity shell 21 near the sliding frame 17. An inner slide 24 is fixedly connected to one end of the pressure-adjusting rod 23 near the pressure gauge 22. A first spring 25 is welded to the inner slide 24 and one inner wall of the cavity shell 21. The first spring 25 is wound around the outside of the pressure-adjusting rod 23. Slide grooves 26 are provided on the inner walls of the three central sides of the cavity shell 21. Slide blocks 27 are slidably connected in the slide grooves 26. The slide blocks 27 are fixedly connected to the three side surfaces of the inner slide 24. The other end of the pressure-adjusting rod 23 close to the sliding frame 17 is fixedly connected to the connecting base frame 28, one end of the connecting base frame 28 is fixedly connected to the center seat 18, and the two sides of the center seat 18 are rotatably connected to the side seats 19, and the three contact wheels 20 are respectively fixedly mounted on the same side surfaces of the center seat 18 and the side seats 19, and a second spring 31 is welded between the side seat 19 and the connecting base frame 28.

[0030] Auxiliary deformation mechanisms include: The sleeve plate fixing frame 30 is fixedly sleeved on the outer side of the other end of the pressure adjustment rod 23 close to the sliding frame 17, and a V-shaped hinge 35 is fixedly installed between the sleeve plate fixing frame 30 and the side seat 19.

[0031] The linkage process of the pressure adjustment mechanism and the auxiliary deformation mechanism is as follows: When the contact wheel 20 contacts the irregular surface of the wall, the pressure adjustment rod 23 drives the inner slide 24 to slide in the cavity shell 21. The first spring 25 elastically generates a reaction force to form an "elastic buffer". The inner slide 24 slides in the slide groove 26 through the three-side sliders 27 to ensure that the pressure transmission direction is consistent. The pressure gauge 22 displays the pressure on the wall surface in real time to meet the flatness detection. When the pressure displayed by the pressure gauge 22 exceeds the preset pressure upper limit, the system automatically reduces the lifting or traversing speed to avoid overload damage to the contact wheel 20. When the curvature of the wall surface changes, the side seat 19 rotates around the center seat 18 under the elastic compression of the second spring 31, and the angle of the V-shaped hinge 35 deforms synchronously with the side seat 19, ensuring that the contact wheel 20 is always tangent to the wall. When the contact wheel 20 leaves the irregular surface area of ​​the wall, the second spring 31 pulls the side seat 19 to reset.

[0032] Example 2, based on the above example: Furthermore, a rotation groove 32 is opened on the central surface of both sides of the center seat 18, and a rotation shaft 33 is limited to rotate in the rotation groove 32. One side surface of the rotation shaft 33 is fixedly connected to the side seat 19, and the outer peripheral surfaces of both ends of the rotation shaft 33 located in the rotation groove 32 are both sleeved with disc spring washers 34.

[0033] The side seat 19 is inserted into the rotation groove 32 of the center seat 18 via the rotation shaft 33 to ensure smooth rotation without jamming. The stepped surfaces at both ends of the rotation shaft 33 contact the end faces of the rotation groove 32 to limit axial movement. The disc spring washer 34 provides preload force to stabilize the rotational friction torque of the side seat 19 within a certain range, avoiding detection errors caused by high-frequency vibration. When the rotation angle of the side seat 19 exceeds 15°, the washer is further compressed to provide additional restoring force to assist in rapid reset. The auxiliary deformation mechanism converts the angular deformation of the contact wheels 20 on both sides into elastic force changes through the V-shaped hinge 35 and the disc spring washer 34, and then transmits it to the pressure gauge after being superimposed with the pressure of the central contact wheel 20, thereby forming a three-dimensional pressure matrix detection model, successfully distinguishing the pressure signal characteristics of the convexity of the wall surface on one side and the inclination of the entire surface, thereby greatly reducing the misjudgment rate during the detection process.

[0034] Furthermore, a pulley assembly 5 is sleeved on the outside of the output shafts of the first motor 3 and the second motor 4 .

[0035] More specifically, in this embodiment, the output shafts of the first motor 3 and the second motor 4 are keyed to a fixed pulley, which is a polyurethane timing belt. The pulley assembly 5 can reduce the speed difference between the output shafts of the first motor 3 and the second motor 4, thereby ensuring that the rotation angle deviation of the vertical screw 6 is reduced.

[0036] 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.
