Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a device for detecting the tilt of building walls. Background Technology

[0002] Building walls are an important component of buildings, serving multiple functions including load-bearing, enclosure, and partitioning. The verticality of the walls is a key indicator for assessing construction quality and structural safety. Excessive tilt not only affects aesthetics but also directly signals structural instability, potentially indicating uneven foundation settlement, structural overload, material aging, or the impact of natural disasters such as earthquakes. During the construction of building walls, tilt detection devices can be used to inspect the walls and ensure construction quality.

[0003] A search revealed CN221198427U, filed on December 14, 2023, which discloses a wall tilt detection device. The device includes a body, a control unit, and a detection component. The control unit and the detection component are fixedly mounted on the body and electrically connected. The detection component includes an electric telescopic rod and several detection modules vertically arranged on the electric telescopic rod. Each detection module is electrically connected to the control unit and includes a detection mechanism and a drive mechanism. This wall tilt detection device uses the electric telescopic rod to raise different detection modules to different heights. By measuring the distance each detection module extends and abuts against the wall, as well as the distance between each detection module, the coordinate positions of different height segments of the wall can be calculated. This yields the wall tilt between each pair of detection modules, allowing users to understand the tilt of different height segments of the wall and promptly rectify any sections with unacceptable tilt, thus improving the efficiency of wall tilt detection and repair.

[0004] However, it still has the following drawbacks in practical use: 1. Existing building wall tilt detection devices directly detect wall tilt through the detection module. If the wall surface is uneven due to debris, it will affect the accuracy of the wall tilt detection. At the same time, the trigger switch is located in the construction environment, lacks protection measures, and is easily damaged. 2. Existing building wall tilt detection devices adjust the height of multiple detection modules using electric telescopic rods. However, this method results in uniform spacing between all detection modules, leading to wasted resources and high costs. Furthermore, the electric telescopic rods are unsuitable for taller walls, limiting their applicability. Therefore, we provide a building wall tilt detection device to address these issues. Utility Model Content

[0005] The purpose of this utility model is to provide a building wall tilt detection device. By setting up a cleaning component, the first motor drives the scraper on the outer wall of the protective plate to rotate, scraping the part of the wall surface to be detected flat, avoiding the impact of the protrusion of the part of the wall surface to be detected on the accuracy of tilt detection. Under the action of the protective plate, the trigger switch inside the sleeve can be shielded, closed and protected to avoid damage. Furthermore, by using a lifting component, the second motor can adjust the height of the second slide, which can meet the detection of most wall tilts and has a wide range of applications.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a building wall tilt detection device, including a base and a vertical frame fixed in the middle of its upper surface. A first slide and a second slide are slidably installed in the lower and upper parts of the inside of the vertical frame, respectively. An electric push rod is installed at the bottom of the first slide. A sleeve is installed in the middle of the outer wall of both the first slide and the second slide. A cleaning component is provided on the outside of the sleeve. A lifting component is provided on one side of the upper surface of the base. The cleaning assembly includes a mounting bracket mounted on the upper surface of the sleeve, and a first motor mounted inside the mounting bracket, with a gear plate mounted on the output shaft of the first motor; The lifting assembly includes a first support plate mounted on the upper surface of the base, and a second motor mounted on the front end face of the first support plate. The output shaft of the second motor is connected to a second rotating shaft via a coupling.

[0007] The present invention is further configured such that wheels are installed at the four corners of the bottom of the base, a control host and a counterweight are installed on both sides of the vertical frame, and a fixing ring is provided on one side of the upper surface of the second slide.

[0008] The present invention is further configured such that a trigger switch is provided on one side of the inside of the sleeve, a moving component is provided on the inside of the trigger switch, and a detection component is provided on one side of the inside of the sleeve.

[0009] The present invention is further configured such that a toothed ring is engaged below the toothed disc, the toothed ring is rotatably sleeved on the outer wall of the sleeve, and protective plates are provided above and below the outer side of the toothed ring.

[0010] The present invention is further configured such that a scraper is fixedly provided in the middle of the outer wall of the protective plate, and connecting plates are fixedly provided at the front and rear ends of the side walls of the protective plate, and a first rotating shaft is fixedly provided inside the connecting plate.

[0011] The present invention is further configured such that a torsion spring is sleeved in the middle of the outer wall of the first rotating shaft, and the front and rear ends of the first rotating shaft are respectively rotatably mounted in bearings on adjacent side plates, with one end of the side plate fixed on the outer wall of the gear ring.

[0012] The present invention is further configured such that the other end of the second rotating shaft passes through the bearing on the first support plate and is connected to the bearing on the second support plate, the bottom of the second support plate is fixed to the upper surface of the base, and a rope winding roller is sleeved on the outer wall of the second rotating shaft.

[0013] The present invention is further configured such that a connecting rope is wound on the outer wall of the rope winding roller, and the other end of the connecting rope passes around the pulley and is connected to the hook. The hook is hung inside the fixing ring, and the pulley is installed on the top of the vertical frame.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a cleaning component, uses a first motor to drive the scraper on the outer wall of the protective plate to rotate, smoothing the area to be tested on the wall surface. This prevents protrusions on the wall surface from affecting the accuracy of tilt detection. Furthermore, the protective plate can shield, close, and protect the trigger switch inside the sleeve, preventing damage. This solves the problems of existing building wall tilt detection devices that directly detect wall tilt through the detection module. If the wall surface is uneven due to debris, the accuracy of the wall tilt detection will be affected. Additionally, the trigger switch is located in the construction environment and lacks protective measures, making it prone to damage.

[0015] 2. This utility model, by setting up a lifting component, allows the second motor to adjust the height of the second slide, which can meet the detection of most wall tilt angles. It has a wide range of applications and solves the problem that existing building wall tilt angle detection devices adjust the height of multiple detection modules by using electric telescopic rods. However, this method results in the same spacing between each detection module, which is wasteful of resources and costly. At the same time, electric telescopic rods are difficult to use on taller walls, which affects the scope of application. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1 Please see Figures 1 to 4 This utility model is a building wall tilt detection device, including a base 100 and a vertical frame 104 fixed in the middle of its upper surface. A first slide 105 and a second slide 106 are slidably installed on the lower and upper sides of the vertical frame 104, respectively. An electric push rod 105a is installed at the bottom of the first slide 105. A sleeve 107 is installed in the middle of the outer wall of both the first slide 105 and the second slide 106. A cleaning component 200 is provided on the outer side of the sleeve 107. The cleaning component 200 includes a mounting bracket 201 installed on the upper surface of the sleeve 107 and a first motor 202 installed inside the mounting bracket 201. A gear 202a is installed on the output shaft of the first motor 202.

[0025] Specifically, wheels 101 are installed at the four corners of the bottom of the base 100; a control host 102 and a counterweight 103 are installed on both sides of the vertical frame 104; a fixing ring 106a is provided on one side of the upper surface of the second slide 106; a trigger switch 108 is provided on one side of the inside of the sleeve 107, a moving component 107a is provided on the inside of the trigger switch 108, and a detection component 107b is provided on one side of the inside of the sleeve 107; a gear ring 203 meshes below the gear disc 202a, and the gear ring 203 is rotatably sleeved on... On the outer wall of the sleeve 107, protective plates 204 are provided above and below the outer side of the toothed ring 203. A scraper 204a is fixed in the middle of the outer wall of the protective plate 204. A connecting plate 204b is fixed in the front and rear ends of the side wall of the protective plate 204. A first rotating shaft 205 is fixed inside the connecting plate 204b. A torsion spring 205a is sleeved in the middle of the outer wall of the first rotating shaft 205. The front and rear ends of the first rotating shaft 205 are respectively rotatably installed in the bearings on the adjacent side plates 206. One end of the side plate 206 is fixed in the outer wall of the toothed ring 203.

[0026] Furthermore, the first slide 105 is height-adjusted via an electric push rod 105a, and the second slide 106 is height-adjusted via a lifting assembly 300. The control host 102, trigger switch 108, moving assembly 107a, detection assembly 107b, and related principles are all existing technologies and will not be described in detail here. The gear disc 202a meshes with the gear ring 203, which serves as a transmission mechanism. Therefore, under the action of the first motor 202, the gear disc 202a can drive the gear ring 203 to rotate synchronously, thereby driving the protective plate 204 and scraper 204a to rotate and clean the wall surface, ensuring that the detection area is flat. When the trigger switch 108 is pushed out via the moving assembly 107a, it can push the protective plate 204 to rotate around the first rotating shaft 205 as the center, opening the protective plate 204. The protective plate 204 can be closed under the elastic action of the torsion spring 205a, and the inner wall of the protective plate 204 is bonded with a waterproof ring to prevent water from entering the sleeve 107.

[0027] The operation process of this embodiment is as follows: In use, the base 100 is pushed to the edge of the wall to be tested, and the scraper 204a is placed against the wall surface. Then, the first slide 105 and the second slide 106 are raised and lowered to appropriate heights by the electric push rod 105a and the lifting assembly 300. The trigger switch 108 is pushed out of the sleeve 107 a certain distance by the moving assembly 107a, so that the protective plate 204 is lifted up by rotating around the first rotating shaft 205. At this time, the scraper 204a on the outside of the protective plate 204 can rotate and touch the part of the wall surface to be tested. Then, the first motor 202 is started. The output shaft of the first motor 202 rotates and drives the gear plate 202a to rotate. The outer wall of the gear plate 202a meshes with the gear ring 203, so the rotation of the gear plate 202a will drive the gear ring 203 to rotate synchronously. The rotation of the gear ring 203 can be achieved through the side plate 206, the first rotating shaft 205, and the connecting plate 204. b drives the protective plate 204 and scraper 204a to rotate. The rotating scraper 204a smooths the wall surface to be tested, preventing the protrusion of the wall surface to be tested from affecting the accuracy of the tilt detection. Then, the moving component 107a is used to push the trigger switch 108 out completely and make it contact the part to be tested. Then, the wall tilt detection is completed by the detection component 107b and the control host 102 (the detection principle of this part is existing technology, so it will not be described in detail here). During the process of the trigger switch 108 being pushed out completely, the protective plate 204 will rotate around the first rotating shaft 205 with the pressure of the trigger switch 108, and squeeze the torsion spring 205a. After the detection is completed and the trigger switch 108 is retracted into the sleeve 107, the protective plate 204 will spring back under the elastic action of the torsion spring 205a, so that the protective plate 204 is closed on the outside of the sleeve 107, which plays a role in shielding, closing and protecting, and preventing damage.

[0028] Example 2 Please see Figure 1 and Figure 5 Based on Embodiment 1, unlike the first embodiment, a lifting assembly 300 is provided. The lifting assembly 300 includes a first support plate 301 installed on the upper surface of the base 100 and a second motor 303 installed on the front end face of the first support plate 301. The output shaft of the second motor 303 is connected to the second rotating shaft 303a through a coupling. This solves the problem that existing building wall tilt detection devices adjust the height of multiple detection modules by means of electric telescopic rods. However, this method results in the same spacing between each detection module, which wastes resources and is costly. At the same time, the electric telescopic rods are difficult to apply to higher walls, affecting the scope of application.

[0029] Specifically, the other end of the second rotating shaft 303a passes through the bearing on the first support plate 301 and is connected to the bearing on the second support plate 302. The bottom of the second support plate 302 is fixed to the upper surface of the base 100. A rope winding roller 304 is sleeved on the outer wall of the second rotating shaft 303a. A connecting rope 305 is wound on the outer wall of the rope winding roller 304. The other end of the connecting rope 305 passes around the pulley 306 and is connected to the hook 305a. The hook 305a is hung inside the fixing ring 106a. The pulley 306 is installed on the top of the vertical frame 104.

[0030] Furthermore, the operation of the second motor 303 can drive the second rotating shaft 303a to rotate, drive the rope winding roller 304 to rotate, wind or release the connecting rope 305, realize the lifting operation of the second slide block 106, and the pulley 306 plays a role in protecting and assisting the sliding of the connecting rope 305, reducing the wear of the connecting rope 305.

[0031] The operation process of this embodiment is as follows: Before detecting the wall tilt, the two sets of trigger switches 108 need to be raised and lowered to a suitable height. The lower first slide 105 and trigger switch 108 are adjusted in height by pushing the electric push rod 105a, while the upper second slide 106 and trigger switch 108 need to be adjusted in height by the lifting assembly 300. During operation, the second motor 303 is started. The output shaft of the second motor 303 rotates and drives the second rotating shaft 303a to rotate through the coupling. The rotation of the second rotating shaft 303a will drive the rope roller 304 on its outer wall to rotate synchronously and release or wind the connecting rope 305. The other end of the connecting rope 305 passes around the pulley 306 and drives the fixing ring 106a and the second slide 106 to rise and fall through the hook 305a, thereby adjusting the height of the second slide 106 and meeting the detection of most wall tilt, with a wide range of applications.
