Traditional wall plastering is done manually, and manual plastering has the defects of uneven plastering thickness, low construction efficiency and high labor cost. In addition, the quality of plastering varies significantly due to the level of workers.

[0003] In order to reduce labor intensity and save construction time, there is a huge demand for intelligent wall plastering machinery in the construction industry.

DETAILED DESCRIPTION

[0027] Before plastering, the flatness and verticality of the wall surface should be strictly checked. The wall surface that does not meet the requirements for flatness and verticality, the misalignment of the template joints, and the uneven concrete surface should be polished; the defects of the concrete components should be repaired. Clean the dirt remaining on the substrate, and fill the gaps between the wire box, wire trough, distribution box bottom box, fire hydrant box and the filling wall with 1:3 cement mortar until the recessed wall surface is 5mm. After the surface of the substrate is cleaned, at the junction of the concrete wall and the brick masonry, as well as the wire pipe, fire extinguisher box, and distribution box through the wall. The wall surface is required to be watered from top to bottom and moistened into the wall. The first watering should be done one day before plastering, and the second watering should be done 3 hours before plastering. There should be no visible water during plastering.

[0028] Will be like Figure 1 The lifting and translating roller-type wall plastering device shown is moved to a suitable position away from the wall, and the top plate 19 is supported on the ceiling by controlling the vertical telescopic mechanism 1. A layer of rubber pad 191 can be fixed on the upper side of the top plate 19 so that it can be supported on the ceiling with a compressive deformation amount, thereby ensuring that the vertical telescopic mechanism 1 of the device is in a stable expanded state.

[0029] Then adjust the device so that the roller wheel 45 contacts and presses the wall. Wherein, translation wheels are respectively installed on both sides of the base 11, so that the device can be translated horizontally in a direction parallel to the wall, and can be transferred. The translation wheels are usually designed to be able to move only in a straight line but not turn, requiring the wheel axle to be horizontal and the wheel bearing to be in close contact with the axle. The device can be carried and moved by the travel wheel. When adjusting the device so that the roller wheel 45 contacts and presses the wall, a telescopic cantilever can be designed, for example, a cantilever including an outer sleeve and an inner sleeve that can be telescopic forward and backward is used, the two are sheathed together, and a locking pin is provided. Alternatively, a cantilever including an outer sleeve and an inner sleeve that can be telescopic forward and backward is used, the two are sheathed together, and a thrust spring is connected between the inner root of the outer sleeve and the inner sleeve to ensure that the inner sleeve always has an outward pressure to ensure that the roller wheel 45 contacts and presses the wall.

[0030] The lifting device 2 of the device can be driven by the lifting drive mechanism 3 to achieve lifting movement, that is, it can control the rolling mechanism 4 to perform lifting movement. After the slurry storage tank 47 is filled with an appropriate amount of slurry, the driving reduction motor of the lifting drive mechanism 3 is controlled by a button. The manual control of the reduction motor can realize the lifting and lifting movement of the lifting device 2 carrying the rolling mechanism 4 together, which can be unidirectional or repeated. In order to ensure that it can stop automatically at the upper and lower limit positions, the lower limit (proximity switch) and the upper limit proximity switch are respectively installed on the base 11 and the top plate 19. When the lifting frame 21 of the lifting device 2 moves to the lowermost end and the uppermost end, it can touch the corresponding proximity switch to ensure that the reduction motor stops or moves in the reverse direction.

[0031] The vertical telescopic mechanism 1 is as follows: Figure 1 As shown, the lower end and upper end of the multi-stage C-shaped sleeve are respectively connected to the base 11 and the top plate 19, and the multi-stage hydraulic cylinder 15 is sleeved inside the multi-stage C-shaped sleeve. The lower end and upper end of the multi-stage hydraulic cylinder 15 are respectively connected to the base 11 and the top plate 19; a rack 18 is vertically arranged on the opening side wall of the multi-stage C-shaped sleeve. Specifically, the multi-stage C-shaped sleeve is as shown in FIG. Figure 4 and Figure 5 As shown, it includes a C-shaped lower sleeve 12, a C-shaped middle sleeve 13 and a C-shaped upper sleeve 14, which are sequentially mounted together. As can be seen from the figure, the opening side walls of each C-shaped sleeve are kept flush, a rack 18 is provided on the opening side walls of each C-shaped sleeve, and a guide mechanism is provided between adjacent C-shaped sleeves. The guide mechanism used in this embodiment is to set an inwardly protruding slider on the lower C-shaped sleeve, and set a vertical slide groove 16 on the upper C-shaped sleeve side wall, and the slider is matched and mounted in the slide groove 16. For example Figure 7 The slider shown in is a bolt-type independent slider 17, or as Figure 8 The screw-type one-piece slider 17a is shown to penetrate the two side walls of the C-shaped sliding sleeve, and the one-piece slider 17a is respectively installed with lock nuts 17b on both sides of the perforations on the two side walls. A connecting plate 141 is also fixed from top to bottom between the upper two side walls of the upper end of the C-shaped upper sliding sleeve 14 located at the uppermost side. The vertical telescopic mechanism 1 can realize its own lifting movement, that is, realize the telescopic movement of the base 11 and the top plate 19, which is realized by controlling the multi-stage hydraulic cylinder 15 (for example, an electrically driven multi-stage jack), and the corresponding button can be set at a suitable position on the outer side wall of the C-shaped lower sliding sleeve 12. When the base 11 and the top plate 19 are unfolded to a certain position, the top plate 19 can be supported on the ceiling, and the button is stopped at this time, or a pressure sensor is installed in the middle of the top plate 19 or on the top of the multi-stage hydraulic cylinder 15. When the pressure sensor senses its pressure limit, the multi-stage hydraulic cylinder 15 is controlled to stop extending. The extension and control of the vertical telescopic mechanism 1 are simple. Every time when it needs to move horizontally, it only needs to control the vertical telescopic mechanism 1 to slightly drop a height difference, and then unfold it again and support it on the ceiling after the horizontal movement.

[0032] Lifting device 2 Figure 2-Figure 4As shown, it includes structural components such as a lifting frame 21, a front axle frame 22 and a rear axle frame 23. The lifting frame 21 is mounted on the outside of the vertical telescopic mechanism 1, and the front and rear sides of the lifting frame 21 are respectively provided with a front axle frame 22 and a rear axle frame 23 connected as one body. As can be seen from the figure, the lifting drive mechanism 3 includes structural components such as a front rotating shaft 31 and a front axle sleeve 32, a rear rotating shaft 37 and a rear axle sleeve 38, a gear 33, a driving mechanism 34 and a rear roller 36. An axial hole is arranged in the side wall of the front axle frame 22 in the transverse direction and a corresponding front axle sleeve 32 is installed. The front rotating shaft 31 is mounted in each front axle sleeve 32, and a gear 33 is mounted on the outside of the front rotating shaft 31, and the gear 33 is meshed with the corresponding rack 18. As can be seen from the figure, the gear 33 has a wide axial length and can be meshed with each rack 18 on the side of the C-shaped lower sleeve 12, the C-shaped middle sleeve 13 and the C-shaped upper sleeve 14 at the same time.

[0033] A driving mechanism, i.e., a reduction motor, is connected to one end of the front shaft 31. The reduction motor is fixed to the side wall of the lifting frame 21. Controlling the rotation of the reduction motor can cause the gear 33 to move up and down along the rack 18, thereby driving the entire lifting device 2 and the rolling mechanism 4 to move up and down. A counterweight 35 can also be fixedly installed at the other end of the front shaft 31 to maintain balance on both sides.

[0034] In order to ensure the meshing degree of the gear 33 when the gear 33 moves along the rack 18, a rear roller 36 with a pressing function is provided on the lifting device 2, and the lifting frame 21 and the rear wall of the multi-stage C-shaped sliding sleeve are pressed by the rear roller 36, so that the gear 33 and the rack 18 are pressed tightly. Specifically, Figure 3 and Figure 4 As shown, a transverse flat hole 24 is arranged in the side wall of the rear axle frame 23 and a corresponding rear axle sleeve 38 is installed. A spring 39 is inserted in the transverse flat hole 24. The rear shaft 37 is inserted in the rear axle sleeve 38. A rear roller 36 is inserted on the outer side of the rear shaft 37. A longitudinal through hole 25 is arranged in the side wall of the rear axle frame 23 behind the transverse flat hole 24. A guide rod 26 is inserted in the through hole 25. The inner end of the guide rod 26 is fixed on the side wall of the rear axle sleeve 38. The rear roller 36 is supported on the rear side wall of the multi-stage C-shaped sliding sleeve.

[0035] like Figure 1 and Figure 6The slurry rolling mechanism 4 shown includes a cantilever 41, a wheel frame 42, a slurry rolling wheel 45, a slurry delivery pipe 46 and a slurry storage pool 47. One end of the cantilever 41 is fixed to the side wall of the lifting frame 21, and the wheel frame 42 is fixed to the upper side of the other end of the cantilever 41. The wheel frame 42 is equipped with a slurry rolling wheel 45 through a roller shaft 43. At the same time, a slurry groove 44 is fixed to the outside of the wheel frame 42. The front side notch of the slurry groove 44 does not exceed the front side edge of the slurry rolling wheel 45, but is higher than the bottom side edge of the slurry rolling wheel 45. The slurry rolling wheel 45 can roll in the slurry groove 44. The bottom of the slurry groove 44 is connected to the slurry storage pool 47 through the slurry delivery pipe 46, so that the height of the slurry layer 48 does not exceed the height of the front side notch of the slurry groove 44.

[0036] The cantilever in this embodiment includes an outer sleeve and an inner sleeve that can be extended and retracted forward and backward. The two are sheathed together, and a thrust spring is connected between the inner root of the outer sleeve and the inner sleeve to ensure that the inner sleeve always has an outward pressure to ensure that the roller wheel 45 contacts and presses the wall.

[0037] The slurry selected in the slurry storage tank 47 is used after adding fine aggregate, cement and a small amount of glue on site. Among them, the cement should be a qualified product with a grade of 32.5 on site, and the fine aggregate should be a qualified medium sand with a mud content of not too large. The type, model, package number, and factory date of the glue used shall be checked in accordance with the provisions of JC / T907 "Concrete Interface Treatment Agent". And it should meet its shear strength, tensile bond strength and other necessary performance indicators. Tap water can be used for mixing the interface agent. Cement, sand, and other basic materials should meet the design requirements and the current national product regulations, and should have a factory certificate. The roller 45 is located in the slurry groove 44 and a part of it is located under the slurry layer 48. When the roller 45 rotates, the slurry in the slurry groove 44 can be adhered to the outer circumference of the roller 45 and brushed on the wall. When the cantilever moves downward or upward, it can drive the roller 45 to rotate along the wall. This operation mode can utilize the slurry storage tank 47 to store an appropriate amount of slurry, eliminating the trouble of repeated slurrying. The slurry storage tank 47 is located at a lower position to replenish the slurry, so there is no need for manual high-level operation, and the device is easy to use. A float valve can be further installed in the slurry storage tank 47, and the float valve is used to ensure that the height of the slurry layer 48 in the slurry tank 44 is located at a constant reference plane. The float valve can ensure that the slurry in the slurry storage tank 47 is discharged into the slurry tank 44 through the slurry delivery pipe 46 only when the height of the slurry layer 48 in the slurry tank 44 is lower than the reference plane.
