[0002] In the field of construction engineering, formwork plays a crucial role as a temporary support structure for molding concrete structures. Currently, formwork is mostly designed modularly and formed by extrusion using specialized equipment, allowing for flexible and free combination according to different structural dimensions. The widespread application of this formwork system has greatly improved the construction efficiency of building projects and occupies an important position in the construction industry.

[0003] Commonly used formwork is categorized by material, primarily including steel and aluminum formwork. However, formwork faces numerous problems after each use. A large amount of concrete adheres to the formwork surface, and rust may occur, resulting in a layer of debris covering the surface. This debris must be thoroughly cleaned before reuse or long-term storage to ensure proper functioning next time. Existing methods for cleaning construction formwork mostly rely on manual cleaning or simple mechanical cleaning equipment. Manual cleaning is labor-intensive, inefficient, and the cleaning effect is difficult to guarantee; while simple mechanical cleaning equipment often cannot adapt to the unevenness of the formwork surface, easily leading to incomplete cleaning. Therefore, there is an urgent need to design a device that can efficiently and effectively clean construction formwork. Utility Model Content

[0037] like Figures 1-5 As shown, this utility model provides a building template cleaning device, which mainly includes a placement platform 1, a robot unit 2, and a cleaning device 3.

[0038] The robot unit 2 is movable and positioned on one side of the placement platform 1, allowing for flexible adjustment of the cleaning position and expanding the applicability of the cleaning device 3. The robot unit 2 is a six-axis robot, which is existing technology. For its specific structure, please refer to the invention patent with authorization announcement number CN 108621182 B.

[0039] The cleaning device 3 is mounted on the robot unit 2 and moves with it. The cleaning device 3 includes a frame 31, a connecting shaft 32, a power component 35, a brush head 33, and a compression spring 34. The frame 31 includes a connecting bracket 311, connecting rods 312, and a mounting plate 313. The connecting bracket 311 is fixedly connected to the robot unit 2. Multiple connecting rods 312 are present, with their upper ends fixedly connected to the connecting bracket 311 and their lower ends fixedly connected to the mounting plate 313. The mounting plate 313 has a through hole, within which a wear-resistant bushing 7 is installed. The wear-resistant bushing 7 is interference-fitted with the through hole. The connecting shaft 32 rotates and slides within the wear-resistant bushing 7 to reduce friction loss. The power component 35 is fixedly mounted on the connecting bracket 311. A connecting sleeve 36 is fixedly mounted at the output end of the power component 35. A spline groove 360 ​​is formed at the lower end of the connecting sleeve 36. The top end of the connecting shaft 32 is fixed... A splined shaft 37, which mates with a splined groove 360, is positioned above the mounting plate 313 and slidably rests within the splined groove 360. The power assembly 35 drives the connecting shaft 32 to rotate through the sliding engagement of the splined groove 360 ​​and the splined shaft 37. This ensures effective power transmission while allowing the connecting shaft 32 to slide up and down within a certain range, further enhancing the self-adaptive capability of the brush head 33. Specifically, the splined shaft 37 has multiple longitudinally extending key teeth arranged around it, and the splined groove 360 ​​has matching keyways to accommodate these key teeth. A clearance fit is used between the key teeth and the keyways to ensure that the splined shaft 37 can slide freely up and down within a certain range without affecting torque transmission. In this embodiment, the power assembly 35 is a motor reducer, which integrates the motor and reducer into a single unit, resulting in a compact structure, high transmission efficiency, and the ability to provide stable and suitable speed and torque for the cleaning process.

[0040] The brush head 33 is connected to one end of the connecting shaft 32 and is located above the placement platform 1, for direct contact and cleaning of the surface of the building template 8. In this embodiment, the end of the brush head 33 is detachably connected to the connecting shaft 32 via a retaining ring 38, facilitating the replacement and maintenance of the brush head 33. The retaining ring 38 is located below the mounting plate 313. Specifically, the retaining ring 38 has an opening, and a connecting lug is integrally formed at the opening. The connecting lug has a mounting hole. The retaining ring 38 is fitted onto the end of the brush head 33 and the end of the connecting shaft 32, and is locked in place by bolts passing through the mounting holes on the two connecting lugs, facilitating operation.

[0041] The compression spring 34 is sleeved on the connecting shaft 32, with one end abutting against the bottom of the mounting plate 313 and the other end abutting against the fixing ring 38, so that the brush head 33 can adaptively conform to the surface of the template 8 during cleaning and polishing to ensure the cleaning effect; it can also adjust the force of the brush head 33 pressing the surface of the template 8 to achieve cleaning and polishing work under different pressures.

[0042] A limiting ring 39 is fixedly installed on the connecting shaft 32. The limiting ring 39 is located between the mounting plate 313 and the spline shaft 37. The diameter of the limiting ring 39 is larger than the diameter of the through hole, and the limiting ring 39 abuts against the top surface of the mounting plate 313. The setting of the limiting ring 39 can limit the lowest position of the brush head 33 sliding downward, prevent the connecting shaft 32 from sliding excessively, and ensure the structural stability of the cleaning device 3.

[0043] Multiple positioning devices 4 are provided on the placement platform 1, and a space for placing the template 8 is provided between the multiple positioning devices 4. The template 8 can be positioned to ensure that the position of the template 8 is fixed during the cleaning process. In this embodiment, the template 8 is clamped and positioned on each side by at least one positioning device 4. Specifically, the positioning device 4 includes a mounting block 41 and an adjusting screw 42. The mounting block 41 is set on the placement platform 1 and has a threaded hole. The adjusting screw 42 passes through the threaded hole. A tightening end cap 43 is fixedly provided at one end of the adjusting screw 42, and a hand handle 44 is fixedly provided at the other end. The position of the tightening end cap 43 can be adjusted by rotating the hand handle 44 to achieve clamping and positioning of the template 8.

[0044] The platform 1 has multiple positioning holes 5. Each positioning device 4 has a pin 6 fixedly installed at the bottom of its mounting block 41, and each pin 6 is inserted into any positioning hole 5. The position of the positioning device 4 can be adjusted according to the size and shape of the template 8, improving the versatility of the device.

[0045] The specific operating steps of this utility model are as follows:

[0046] When it is necessary to clean the template 8, the template 8 is manually moved to the platform of the placement table 1 using an auxiliary hoist. Then, the pin 6 of the positioning device 4 is inserted into the positioning hole 5 on the workbench, so that the end cap of the positioning device 4 is aligned with the side of the template 8. The hand handle 44 is turned to drive the adjusting screw 42 to move forward relative to the mounting block 41, so that the tightening end cap 43 is pressed against the side of the template 8. After performing the above operations on multiple fixing devices in sequence, the template 8 is fixed in multiple directions.

[0047] Start robot unit 2, which carries cleaning device 3 to polish and clean the surface of building template 8 according to a preset path.

[0048] During operation, the cleaning device 3 uses a motor reducer to drive the connecting shaft 32 to rotate via the spline groove 360 ​​of the coupling sleeve 36 and the spline shaft 37. The connecting shaft 32 then drives the brush head 33 to rotate, polishing and cleaning the surface of the template 8. Simultaneously, the pressure of the compression spring 34 keeps the brush head 33 in constant contact with the surface of the template 8. When there are protruding debris on the surface of the template 8, the debris pushes the brush head 33 upwards, causing the compression spring 34 to contract. The spline shaft 37 then slides upwards within the spline groove 360, allowing the brush head 33 to adapt to the unevenness of the template 8 surface. At this time, under the pressure of the compression spring 34, the brush head 33 experiences increased pressure, effectively removing the protruding debris and ensuring a thorough cleaning and polishing effect.

[0049] Additionally, when fine-tuning of the clamping force between the brush head 33 and the template 8 surface is required, the height of the connecting bracket 311 can be adjusted using the robot unit 2. As the height of the connecting bracket 311 changes, the splined shaft 37 at the end of the connecting shaft 32 slides up and down accordingly within the splined groove 360 ​​of the output sleeve of the power assembly 35. During this process, the compression spring 34 sleeved on the connecting shaft 32 undergoes elastic deformation under stress, adjusting the pressure applied to the brush head 33 by changing its own degree of compression. In this way, the brush head 33 can stably and efficiently complete the cleaning and polishing operation under different pressures from the compression spring 34, according to the actual cleaning needs of the template 8.
