Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a wall cleaning device for building engineering. Background Technology

[0002] During the main structural construction phase of a building, after the masonry work is completed, the wall surface generally needs to be cleaned. The main cleaning tasks include removing mortar overflow from the joints, dust accumulation, and temporary positioning marks. Mortar overflow mainly refers to the bulges formed by the foundation mortar during masonry work, while dust accumulation mainly consists of debris from the powdering of aerated concrete blocks. Traditionally, wall cleaning is done manually using tools such as scrapers, which is time-consuming, labor-intensive, and requires auxiliary tools like scaffolding for access, making the process cumbersome and inefficient.

[0003] A search revealed a wall cleaning device for building engineering, Chinese Patent Publication No. CN222815703U. The device includes a housing, a cutting module, and a cleaning assembly. The cleaning assembly is mounted on the upper part of the housing's inner cavity. The cutting module includes a cutting component, an elastic monitoring component, a limiting component, and a collection groove. A rectangular cavity is formed on the left wall of the housing, and a rubber sheet is fixedly installed on the outer periphery of the left wall. The cutting component is movably mounted inside the housing. One end of the elastic monitoring component is mounted on the inner wall of the housing. The limiting component is mounted on the inner wall of the housing, and the collection groove is mounted on the output end of the limiting component. This invention designs a cutting module and a cleaning assembly, which can effectively clean wall protrusions and dust. The entire wall cleaning process is simple to operate, highly efficient, and results in a smooth wall surface after cleaning. It also recovers dust and protrusions, avoiding environmental impact.

[0004] While this device improves the cleaning method to some extent, it still has shortcomings: its cutting component has a complex structure, with components such as a fixed shaft, deflection cylinder, blade, and internal torsion spring working together, increasing the risk of device failure and maintenance costs. The elastic monitoring component uses an arc-shaped cylinder, arc-shaped rod, spring, and pressure sensor to detect protrusions, a process easily affected by external interference, leading to inaccurate detection. The cleaning component is driven by a motor to drive the drive wheel, which in turn drives the driven wheel via a transmission belt, thus rotating the cleaning structure for cleaning. This power transmission involves many links, resulting in significant energy loss, and the cleaning effect is affected by factors such as the tension of the transmission belt. Furthermore, the device lacks flexibility in overall movement and height adjustment, making it difficult to quickly adapt to the cleaning needs of different wall surfaces. Therefore, we propose a wall cleaning device for building engineering. Utility Model Content

[0005] The purpose of this invention is to provide a wall cleaning device for building engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A wall cleaning device for building construction includes a base with a lifting assembly on top.

A wall cleaning assembly is connected to the front of the lateral movement adjustment assembly. Dust suction assemblies are located at the top and bottom of the lateral movement adjustment assembly. The lifting assembly drives the telescopic distance adjustment assembly to move vertically, the telescopic distance adjustment assembly adjusts the distance between the lateral movement adjustment assembly and the wall, and the lateral movement adjustment assembly moves the wall cleaning assembly horizontally. The lifting assembly, telescopic distance adjustment assembly, and lateral movement adjustment assembly work together to create a three-dimensional spatial movement trajectory for the wall cleaning assembly, achieving all-around cleaning of the wall. The dust suction assemblies are used to absorb dust and debris generated during the wall cleaning process in real time.

A collection box is located on the top of the device base near the other side of the back. A vacuum cleaner is located on the top of the collection box, and a pipe connects the vacuum cleaner and the vacuuming seat. A door is hinged to the back of the collection box.

[0013] As a preferred embodiment of this utility model, multiple casters are fixedly connected to the bottom of the device base around its perimeter. The casters are universal casters with brakes, and the wheel surfaces are made of polyurethane material.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this utility model, the device base is equipped with universal wheels with brakes. The polyurethane wheel surface is wear-resistant and quiet, making it easy to move the device to the working position. The braking function can quickly fix the device. Compared with traditional climbing assistance tools, it is easier and safer to operate. The lifting assembly, through the cooperation of a first drive motor, a first lead screw, and a linear guide, achieves stable vertical lifting of the moving seat, precisely adjusting the cleaning height to easily cover different wall areas. This solves the problem of high-altitude cleaning with traditional equipment. Compared to the complex cutting assembly in the prior art, the components in this application have a simpler structural design. For example, the telescopic distance adjustment assembly, composed of an electric push rod, precisely controls the distance between the cleaning assembly and the wall, reducing the risk of failure and maintenance costs.

Together with the lifting assembly and the telescopic distance adjustment assembly, the grinding disc efficiently completes all-round cleaning of the wall, avoiding energy loss and unstable results. The third drive motor of the wall cleaning assembly drives the grinding disc for powerful cleaning, eliminating the need for complex monitoring structures. The dust collection assembly adsorbs debris in real time, and multi-stage filtration ensures stable suction and avoids dust interference. Compared to the monitoring issues in the prior art, which are easily affected by interference, the cleaning effect is more reliable. Attached Figure Description

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0021] like Figure 1-4As shown, this utility model provides a technical solution: a wall cleaning device for building engineering, including a device base 1, a lifting component 2 on the top of the device base 1, a telescopic distance adjustment component 3 connected to the front of the lifting component 2, a horizontal movement adjustment component 4 connected to one end of the front of the telescopic distance adjustment component 3, a wall cleaning component 5 connected to the front of the horizontal movement adjustment component 4, and dust suction components 6 on the top and bottom of the horizontal movement adjustment component 4; the lifting component 2 is used to drive the telescopic distance adjustment component 3 to move vertically, the telescopic distance adjustment component 3 is used to adjust the distance between the horizontal movement adjustment component 4 and the wall, and the horizontal movement adjustment component 4 is used to drive the wall cleaning component 5 to move horizontally; the lifting component 2, the telescopic distance adjustment component 3, and the horizontal movement adjustment component 4 work together to make the wall cleaning component 5 form a three-dimensional spatial movement trajectory, realizing all-round cleaning of the wall; the dust suction component 6 is used to absorb dust and debris generated during the wall cleaning process in real time. The lifting assembly 2 includes two support frames 201, with a lifting base 202 between them. The lifting base 202 has a first sliding groove 203 on its front side, and a first lead screw 204 is installed in the first sliding groove 203. The first lead screw 204 is threadedly connected to a movable seat 2041. The movable seat 2041 moves vertically within the first sliding groove 203 through threaded engagement with the first lead screw 204. By utilizing the lead screw transmission principle, the rotational motion of the first lead screw 204 is converted into the vertical linear motion of the movable seat 2041, thereby realizing the position adjustment of the cleaning assembly in the height direction of the wall. This allows the device to cover wall areas of different heights, solving the problem that traditional cleaning equipment has difficulty cleaning high walls.

[0022] A first drive motor 205 is mounted on the top of the support frame 201, and its output end is connected to one end of the first lead screw 204 to drive the first lead screw 204 to rotate. Linear guide tubes 206 are fixedly connected to both sides between the two support frames 201. The movable seat 2041 is slidably connected to the linear guide tubes 206. The linear guide tubes 206 guide and stabilize the movement of the movable seat 2041. The first drive motor 205 provides power to the lifting assembly 2, ensuring the stable lifting and lowering of the movable seat 2041. The linear guide tubes 206 cooperate with the movable seat 2041 to limit the direction of movement of the movable seat 2041, preventing it from swaying or deviating during lifting and lowering, thus enhancing the smoothness and reliability of the lifting motion. A servo motor can be used as the first drive motor 205, enabling precise speed and position control to meet the precise lifting height requirements of different cleaning tasks. The surface of the linear guide tubes 206 can be treated with wear-resistant materials to reduce friction with the movable seat 2041, extend its service life, and reduce maintenance costs.

[0023] The telescopic distance adjustment component 3 includes an electric push rod 301. The output end of the electric push rod 301 is connected to a horizontal base 302. Auxiliary guide tubes 303 are fixed to both sides of the back of the horizontal base 302 and are slidably connected to the movable seat 2041. The electric push rod 301, through rapid and precise telescopic movements, drives the horizontal base 302 and subsequent components to move closer to or away from the wall. It can dynamically adjust the working distance between the cleaning components and the wall according to the actual flatness of the wall and the cleaning needs, ensuring that the grinding disc 503 maintains the best contact state with the wall and improving the cleaning effect.

[0024] The lateral movement adjustment component 4 includes a second slide groove 401 formed on the front of the lateral base 302. A second lead screw 402 is provided in the second slide groove 401. The second lead screw 402 is threadedly connected to a slider 403. A second drive motor 404 is provided on one side of the lateral base 302. Its output end is connected to the second lead screw 402. The second drive motor 404 drives the second lead screw 402 to rotate, causing the slider 403 to move horizontally in the second slide groove 401. By driving the second lead screw 402 to rotate through the second drive motor 404, the rotational motion is converted into the horizontal linear motion of the slider 403 using the lead screw and nut transmission principle. This enables the wall cleaning component 5 to reciprocate in the horizontal direction. In conjunction with the lifting component 2 and the telescopic distance adjustment component 3, a complete cleaning coverage area can be formed on the wall.

[0025] The wall cleaning component 5 includes a mounting bracket 501 fixedly connected to the slider 403. A third drive motor 502 is installed inside the mounting bracket 501. The output end of the third drive motor 502 is connected to a grinding disc 503. The third drive motor 502 drives the grinding disc 503 to rotate, grinding and cleaning the wall surface. The third drive motor 502 provides rotational power to the grinding disc 503. The high-speed rotating grinding disc 503 removes stains, paint residue, rough protrusions, etc. on the wall surface through friction, achieving the smoothing and cleaning of the wall surface. It is the core execution component of the device to complete the cleaning task.

[0026] The dust collection assembly 6 includes two dust collection seats 601, each with a dust collection port 602 on its front. A collection box 603 is located on the top of the device base 1 near the other side of the back. A vacuum cleaner 604 is mounted on top of the collection box 603. The vacuum cleaner 604 and the dust collection seats 601 are connected by a pipe. The vacuum cleaner 604 collects the dust and debris sucked in by the dust collection port 602 of the dust collection seat 601 into the collection box 603 through the pipe. A door is hinged to the back of the collection box 603 for cleaning the garbage inside the collection box 603. The negative pressure generated by the vacuum cleaner 604 is transmitted to the dust collection seat 601 through the pipe. The dust collection port 602 sucks in the dust and debris generated during the cleaning process and collects it into the collection box 603 in a timely manner, effectively reducing dust at the work site, improving the construction environment, protecting the health of operators, and preventing dust from polluting the surrounding environment.

[0027] Multiple casters 7 are fixed around the bottom of the device base 1. The casters 7 are universal casters with brakes and the wheel surface is made of polyurethane material. The casters 7 facilitate the overall movement of the device, and the braking function can fix the position of the device. The polyurethane wheel surface has good wear resistance and quietness.

[0028] The working process of this utility model is as follows: When using a wall cleaning device for construction engineering, the operator first pushes the device and uses the braked casters at the bottom of the device base 1 to flexibly move the entire wall cleaning device to a suitable position near the wall to be cleaned. After reaching the designated position, the casters are locked by the braking function to prevent the device from shifting during subsequent operations. The polyurethane wheel surface ensures that the movement is smooth, quiet and wear-resistant, providing a stable foundation for subsequent work. The first drive motor 205, located at the top of the support frame 201, is activated. The output end of the first drive motor 205 is connected to the first lead screw 204, which drives the lead screw 204 to rotate. Based on the height of the wall to be cleaned, the movable seat 2041, which is threadedly connected to the first lead screw 204, moves vertically within the first slide groove 203 on the front of the lifting base 202 using the lead screw transmission principle. At the same time, the straight guide tubes 206 on both sides between the two support frames 201 guide and stabilize the movable seat 2041, ensuring that the vertical lifting process of the movable seat 2041 is smooth and does not deviate. This allows the subsequent components installed on the movable seat 2041 to reach the corresponding height of the wall, covering areas of different heights and solving the problem of difficulty in cleaning high walls with traditional equipment. Based on the actual flatness of the wall and the cleaning requirements, the electric push rod 301 is activated. The output end of the electric push rod 301 is connected to the horizontal base 302. Through a quick and precise telescopic movement, the horizontal base 302 is driven to telescopically move along the auxiliary guide tubes 303 that are slidably connected to the movable seat 2041 on both sides of its back side. This adjusts the distance between the horizontal movement adjustment component 4 and the wall, ensuring that the grinding disc 503 in the wall cleaning component 5 installed on the horizontal movement adjustment component 4 maintains the optimal working distance from the wall, creating conditions for efficient wall cleaning. The second drive motor 404 on one side of the horizontal base 302 is started, and its output end drives the second lead screw 402 to rotate. The second lead screw 402 is threadedly connected to the slider 403. Driven by the second drive motor 404, the slider 403 moves horizontally in the second slide groove 401 on the front of the horizontal base 302. The slider 403 is fixed to the mounting bracket 501 of the wall cleaning component 5, thereby driving the entire wall cleaning component 5 to reciprocate in the horizontal direction. At the same time, the third drive motor 502 in the mounting bracket 501 drives the grinding disc 503 to rotate at high speed. The grinding disc 503 removes stains, paint residue, rough protrusions, etc. on the wall surface through friction, realizing the smoothing and cleaning of the wall surface. The horizontal movement adjustment component 4, the lifting component 2, and the telescopic distance adjustment component 3 work together to make the grinding disc 503 form a complete cleaning coverage area on the wall surface, realizing all-round cleaning of the wall surface. While the wall cleaning component 5 is sanding and cleaning the wall, the vacuuming components 6 located at the top and bottom of the horizontal movement adjustment component 4 work simultaneously. The vacuum cleaner 604 on the other side of the back of the device base 1 generates negative pressure, which is transmitted through pipes to the two vacuum seats 601. The suction port 602 on the front of the vacuum seat 601 sucks in the dust and debris generated during the cleaning process and collects them into the collection box 603 through pipes. The door on the back of the collection box 603 facilitates the later cleaning of the garbage inside. The multi-stage filtration device ensures that the suction power of the vacuum cleaner 604 is stable and prevents fine dust from leaking out, effectively reducing dust in the work area, improving the construction environment, protecting the health of operators, and avoiding dust pollution to the surrounding environment.
