[0002] In building construction, the wall project is a large-scale, costly, and high-quality requirement operation project. At present, in the construction industry, multiple processes such as wall cleaning, plastering, and grinding have always been achieved by manual operation, which not only has a high labor intensity, low efficiency, and long construction time. With the improvement of the economic level and the popularization of higher education, plastering workers with professional skills have become scarce and expensive, resulting in the increasing cost of this process year by year while the quality is difficult to guarantee. Since the existing construction workers rely entirely on personal experience for construction, the construction quality cannot be guaranteed and the construction standards cannot be unified. On the other hand, in modern building construction, the accuracy requirements are getting higher and higher, and traditional tools can no longer meet the construction requirements. Therefore, some more advanced tools are needed to ensure the construction quality and efficiency. Most of the construction aligners and tools on the market currently use methods such as linear measurement and mechanical rotation for measurement and positioning, which have disadvantages such as low accuracy and susceptibility to external influences. Some existing technologies design construction wall robots. The robot technology has a high cost, is not applicable to general building construction fields, and requires a high level of operation skills and high maintenance costs, making it difficult to popularize and apply.

As can be seen from the figure, there are two upper and lower pressure plates 16, and each time before the support frame is moved, the working area occurs in a certain area between the upper and lower pressure plates.

[0025] like Figure 1 and Figure 2 As shown, the sliding seat assembly 2 includes a movable base 21 , a slider 22 and a clamp 23 . The slider 22 is transversely fixed to the middle of both sides of the rear wall of the base 21 , and the clamp 23 is used to clamp the material pipe 36 .

[0026] A concave track groove is provided on the front side of the guide rail 13, and the slider 22 is matched and sleeved in the track groove, so that the movable base 21 can slide freely left and right along the guide rail 13. The end of the track groove is blocked to prevent the slider from falling out.

[0027] A working unit 3 is movably connected to the front side of the sliding seat assembly 2. Figures 1-3 As shown, the working unit 3 includes a working base 31, an upper pulley box 32, a lower pulley box 33, rollers 34, a diverter box 35, a material pipe 36 and a nozzle 37. The upper pulley box 32 and the lower pulley box 33 are fixed to the upper and lower parts of the front side of the working base 31, respectively. The upper pulley box 32 and the lower pulley box 33 are provided with perforations at corresponding positions and are installed with sleeves. The rollers 34 are installed in the corresponding pair of sleeves. Each roller 34 includes a cylindrical roller body and two end shafts. The two end shafts are located inside the corresponding gear box and are respectively installed with pulleys. Each pulley in the upper pulley box 32 is surrounded by a toothed belt at the same time, and each pulley in the lower pulley box 33 is surrounded by a toothed belt at the same time. At least one or a pair of end shafts are led downward out of the lower pulley box and are connected to the driving assembly 7 installed at the bottom of the working base 31. The driving assembly 7 is used to drive at least one group of rollers 34 to rotate.

[0028] A nozzle 37 is installed in the middle of the front side wall of the working base 31 or in the area between any adjacent rollers 34. The parts of each nozzle located on the rear wall of the working base 31 are collected in a diverter box 35, and an interface is provided on the diverter box 35 and connected to the material pipe 36.

[0029] To improve the support strength between the sliding seat assembly 2 and the working unit 3, an auxiliary frame 24 is additionally provided between the two. Specifically, four rear hinge seats 25 are respectively arranged at the four top corner positions of the front side wall of the moving base 21 of the sliding seat assembly 2, and four front hinge seats 26 are respectively arranged at the four top corner positions of the rear side wall of the working base 31 of the working unit 3. The auxiliary frame 24 includes two sets of left and right folding swing rods. Each set of folding swing rods includes a pair of front swing rods and a pair of rear swing rods. The front and rear swing rods are hinged together by a pin shaft. Each rear swing rod is respectively hinged to the four rear hinge seats 25 by a pin shaft, and each front swing rod is respectively hinged to the four front hinge seats 26 by a pin shaft.

[0030] As Figure 2 and Figure 5 shown, the grating assembly 4 includes a laser generator 41 installed on the upper side of the sliding seat assembly 2 and a laser receiver 42 installed on the upper side of the pressing plate 16, and their positions correspond to each other. At the same time, a grating plate 43 is installed on the upper side of the working unit 3. The grating plate 43 is distributed with a series of equally spaced lines, but each line has a different width. The controller controls the laser generator 41 to emit a laser signal and receives the induction signal of the laser receiver 42 to judge the moving position of the working unit 3.

[0031] An induction unit is installed between the sliding seat assembly 2 and the working unit 3. The controller judges whether the working unit 3 is in contact with the wall surface through the signal of this induction unit. When the controller detects that the working unit is in contact with the wall surface, according to the pressing timing of the transfer button 81 and the pumping button 82 on the handle, the limit position of the working range of the working unit is determined and this setting is recorded. Before the function switch is pressed next time, the original setting is specified to be executed. The driving component is sensed and controlled through the grating assembly to ensure that the working unit works within the set range.

[0032] One form of the induction unit adopts a telescopic induction mechanism 5 as Figure 2 shown. The telescopic induction mechanism 5 includes an induction rod 51 and an inductor 52. The induction rod 51 is vertically fixed to the rear wall of the working base 31 of the working unit 3, and the inductor 52 is installed on the front wall of the base 21 of the sliding seat assembly 2. The inductor 52 is provided with a through hole, and the rear end of the induction rod 51 is inserted into the through hole in a matching manner. A thrust spring is installed at the bottom of the inner cavity of the inductor housing, a slider is installed at the end of the thrust spring, and a pressure sensor is installed on the slider. The signal line of this pressure sensor is connected to the signal input end of the controller. When the support frame 1 is held and the working unit 3 is pressed against the wall surface, the induction rod 51 will press the slider to move backward. At the same time, the pressure sensor provides a signal of increasing pressure to the controller, and the controller judges to enter the working mode from this, controls the roller to rotate and controls the material pipe to open for feeding.

[0033] This embodiment can further add an auxiliary leveling mechanism 6, such as Figure 3As shown, the auxiliary flattening mechanism 6 includes a moving shaft seat 61, side shafts 62, and side rollers 63. The moving shaft seat 61 is hinged to the edge of the working base 31 of the working unit 3 through the upper and lower side shafts 62, and the side rollers 63 are also installed on the moving shaft seat 61 through pin shafts. A torsion spring is installed on the side shafts 62 so that the moving shaft seat 61 tilts forward in the natural state. At the same time, an electromagnet is installed between the working base 31 and the moving shaft seat 61. The controller controls the electromagnet to be in the attracted state at the initial stage of work, that is, to keep the side shafts at the rear. At the end of multiple reciprocating rolling presses, the moving shaft seat 61 is controlled to pop outwards so that the side rollers 63 can finally press against the wall to play a correcting role.

[0034] As Figure 4 shown, the driving assembly 7 includes a motor seat 71, a driving motor 72, and a driving gearbox 73. The motor seat 71 is fixed to the rear wall of the working base 31 of the working unit 3, the driving motor 72 is fixed on the motor seat 71, and at least one driving gearbox 73 is fixed in the area between the two motor seats 71. The rotating shaft of the driving motor 72 is connected to the input shaft of the corresponding driving gearbox 73, and the output shaft of the driving gearbox 73 is in transmission connection with the end shaft of any roller.

[0035] The function switch 8 includes a transfer button 81 and a pumping button 82, which are respectively located on the upper sides of the two handles, as Figure 5 shown.

[0036] The working principle of this embodiment is as follows: Hold the two handles with both hands, and the moving support frame 1 can drive the sliding seat assembly 2 and the working unit 3 to move together. According to the range of the wall surface to be sprayed and rolled, the upper and lower pressing plates 16 are manually pressed against the wall surface first to make the whole support frame 1 stable. As Figure 7 shown, the controller controls the working unit 3 to move along the wall and spray and roll (or other construction machinery) according to the wall-touching signal provided by the telescopic induction mechanism 5. For the first time, it is necessary for manual to judge the walking range of the working unit 3, and press the transfer button 81 and the pumping button 82 respectively. After pressing, the working unit 3 stops moving or stops spraying, and the controller records the working range corresponding to the stop button. After holding the support frame and moving down one working position again, after the controller detects the wall-touching signal, it directly controls the working unit 3 to execute the working procedure and automatically runs according to the previous working range, unless the function switch is manually pressed again. This construction tool saves a great deal of manpower to a large extent. During construction, only need to hold this tool and press it against the corresponding position on the wall surface. The controller can control the equipment to continue working according to the manual pressing signal and the signal feedback by the grating assembly. The middle working unit 3 of this hand-held tool can work automatically and reciprocally for multiple times to ensure the working quality.
