Description

Technical Field

[0001] The present invention relates to the technical field of autoclaved aerated concrete slabs, and specifically to a roughening device for autoclaved aerated concrete slabs. Background Art

[0002] Autoclaved aerated concrete slabs are a kind of lightweight and porous new type of green environmental protection building material mainly made of cement, lime, silica sand, etc., and different numbers of steel mesh sheets treated with anti-corrosion are configured according to structural requirements. Through high-temperature and high-pressure steam curing, autoclaved aerated concrete slabs with porous crystals are produced. Its density is smaller than that of general cementitious materials, and it has excellent fire resistance, fireproofing, sound insulation, heat insulation, heat preservation and other unparalleled properties.

[0003] In order to facilitate the pasting of smooth autoclaved aerated concrete slabs on the wall, it is often necessary to roughen the surface of the autoclaved aerated concrete slabs, that is, to draw many grooves on the autoclaved aerated concrete slabs to facilitate the pasting of the autoclaved aerated concrete slabs on the wall. Conventional roughening devices often directly move the roughening rod on the autoclaved aerated concrete slab to achieve roughening treatment. For example, a surface roughening mechanism for autoclaved aerated concrete slabs described in the patent application No. 202110871387.8, after clamping and limiting the autoclaved aerated concrete slab, controls the first telescopic rod to make the roughening rod roughen the surface of the autoclaved aerated concrete slab. It can be seen that it simply uses the roughening rod to directly roughen the autoclaved aerated concrete slab, with relatively large friction, which is likely to cause large-area peeling on the surface of the autoclaved aerated concrete slab. Therefore, a roughening device for autoclaved aerated concrete slabs is specifically proposed, which first performs rotary drilling and positioning, and then performs overall roughening treatment, effectively avoiding the occurrence of large-area peeling on the surface of the autoclaved aerated concrete slab. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a roughening device for autoclaved aerated concrete slabs, which solves the problem that when the surface of a conventional autoclaved aerated concrete slab is roughened, the friction is relatively large, which is likely to cause large-area peeling on the surface of the autoclaved aerated concrete slab.

[0005] To achieve the above object, the present invention provides the following technical solution: a roughening device for autoclaved aerated concrete slabs, comprising a covering box and a roughening assembly disposed inside the covering box. A handle is fixedly installed at the top of the back of the covering box, and transparent observation windows are provided on both the front and back of the covering box. A height adjustment assembly is slidably installed inside the covering box. Both ends of the roughening assembly are rotatably installed inside the height adjustment assembly through a rotating shaft. A driving member adapted to the roughening assembly is slidably installed on the left side of the covering box for driving the roughening assembly to rotate. The roughening assembly includes an assembly plate. A first slot is opened at the bottom of the assembly plate. A first serrated plate is slidably installed inside the first slot, and the first serrated plate and the assembly plate are fixedly connected by a first bolt. A second slot is opened at the top of the back of the assembly plate, and a second serrated plate is slidably installed inside the second slot. A return spring is fixedly connected between the front of the second serrated plate and the second slot. Top holes communicating with the second slot are opened on both the left and right sides of the front of the assembly plate. A pin pressing assembly adapted to the top holes is provided at the top of the covering box.

[0006] By adopting the above technical solution, the driving member is used to drive the assembly plate to rotate. During the movement of the covering box, the first serrated plate punches holes at intervals on the surface of the autoclaved aerated concrete slab, dividing the surface of the autoclaved aerated concrete slab into several sections of roughening areas to be treated. By controlling the rotation of the assembly plate by the driving member, the pin pressing assembly is inserted into the top holes, and the second serrated plate is extruded to the punched holes on the autoclaved aerated concrete slab. By moving the covering box, the roughening treatment can be carried out on several sections of roughening areas to be treated. While shortening the overall roughening stroke, the situation of large-area peeling on the surface of the autoclaved aerated concrete slab is effectively avoided.

[0007] The present invention is further configured as follows: the height adjustment assembly includes an adjustment screw rod, a cross plate, and two vertical plates. The bottom end of the adjustment screw rod is rotatably connected to the top of the cross plate through a bearing, and the left and right sides of the bottom of the cross plate are respectively fixedly connected to the tops of the two vertical plates.

[0008] The present invention is further configured as follows: the adjustment screw rod penetrates and is threadedly connected to the top of the covering box. The opposite sides of the two vertical plates are respectively in sliding contact with the left and right sides of the inner cavity of the covering box, and both the left and right sides of the assembly plate are rotatably installed between the two vertical plates through a rotating shaft.

[0009] By adopting the above technical solution, the height of the cross plate is adjusted by using the adjustment screw rod, so that the vertical plates drive the assembly plate to adjust the height, achieving the purpose of adjusting the roughening depth, and it is simple and convenient to use.

[0010] The present invention is further configured as follows: the driving member includes a U-shaped sleeve frame and a driving motor. The driving motor is fixedly installed on the left side of the U-shaped sleeve frame.

[0011] The present invention is further configured such that: the U-shaped sleeve frame is slidably connected to the left side of the covering box, the output shaft of the driving motor penetrates through the U-shaped sleeve frame and is fixedly connected to one end of the rotating shaft of the hair-raising assembly, and a long slot adapted to the output shaft of the driving motor is provided on the left side of the covering box.

[0012] By adopting the above technical solution, with the cooperative arrangement of the U-shaped sleeve frame, the covering box and the long slot, it can effectively ensure that the driving motor rises and falls with the lifting of the vertical plate, enabling the driving motor to effectively cooperate with the rotating plate to perform hair-raising treatment on the surface of the autoclaved aerated concrete board.

[0013] The present invention is further configured such that: the pin extrusion assembly includes a telescopic rod, a linkage plate and two insertion rods, the telescopic end of the telescopic rod is fixedly connected to the bottom of the linkage plate, and the left and right sides of the bottom of the linkage plate are respectively fixedly connected to the tops of the two insertion rods.

[0014] The present invention is further configured such that: the telescopic rod is fixedly installed at the top of the inner cavity of the covering box, and the telescopic end of the telescopic rod penetrates through the covering box, the bottom ends of the two insertion rods sequentially penetrate through the covering box and the cross plate and extend below the cross plate, and the insertion rods are used in cooperation with the top holes.

[0015] By adopting the above technical solution, with the arrangement of the telescopic rod, it drives the linkage plate to insert the two insertion rods into the top holes, realizing the position limitation of the assembly plate and simultaneously extruding and limiting the second serrated plate, ensuring that the second serrated plate can effectively perform hair-raising treatment on the surface of the autoclaved aerated concrete board under the limitation of the insertion rods, which is convenient to use and the hair-raising is stable.

[0016] The present invention is further configured such that: a chute communicating with the second slot is provided at the top of the assembly plate, the assembly plate and the second serrated plate are fixedly connected by a second bolt, and the outer surface of the second bolt is in sliding contact with the inner surface of the chute.

[0017] By adopting the above technical solution, the second bolt is used to ensure the tight connection between the second serrated plate and the assembly plate, avoiding the situation that the second serrated plate falls off during the rotation of the assembly plate. With the arrangement of the chute, it ensures that the second serrated plate can effectively slide in the second slot when being extruded by the insertion rod, further ensuring the smooth progress of the hair-raising treatment on the surface of the autoclaved aerated concrete board.

[0018] The present invention provides a hair-raising device for autoclaved aerated concrete boards. It has the following beneficial effects:

[0019] (1) In the present invention, the driving member is utilized to drive the assembly plate to rotate. During the movement of the covering box, the first serrated plate perforates the surface of the autoclaved aerated concrete board at intervals, dividing the surface of the autoclaved aerated concrete board into several sections of areas to be roughened. By controlling the rotation of the assembly plate through the driving member, the pin extrusion assembly is inserted into the top hole, and the second serrated plate is extruded to the perforated position on the autoclaved aerated concrete board. By moving the covering box, the roughening treatment can be carried out on several sections of areas to be roughened. While shortening the overall roughening stroke, it effectively avoids the occurrence of large-area peeling on the surface of the autoclaved aerated concrete board.

[0020] (2) In the present invention, by utilizing the adjusting threaded rod to adjust the height of the cross plate, the vertical plate drives the assembly plate to adjust the height, achieving the purpose of adjusting the roughening depth, and it is simple and convenient to use.

[0022] (4) In the present invention, through the setting of the telescopic rod, the linkage plate is driven to insert the two insertion rods into the top hole. While achieving the position limitation of the assembly plate, the second serrated plate is extruded and limited, ensuring that the second serrated plate can effectively roughen the surface of the autoclaved aerated concrete board under the limitation of the insertion rods. It is convenient to use and the roughening is stable.

[0023] (5) In the present invention, by using the second bolt to ensure the tight connection between the second serrated plate and the assembly plate, avoiding the situation of the second serrated plate falling off during the rotation of the assembly plate.

The adjustment screw rod 14 passes through and is threadedly connected to the top of the covering box 1. The opposite sides of the two vertical plates 16 are respectively in sliding contact with the left and right sides of the inner cavity of the covering box 1. The left and right sides of the assembly plate 5 are rotatably installed between the two vertical plates 16 through rotating shafts. By rotating the adjustment screw rod 14, the assembly plate 5 can be driven to rise and fall, thereby realizing the adjustment of the roughening depth.

[0041] As a preferred solution, in order to drive the assembly plate 5, as shown in the appended Figure 1 and the appended Figure 2 and the appended Figure 3 figures, the driving member 4 includes a U-shaped sleeve frame 17 and a driving motor 18.

[0044] As a detailed description, the covering box 1 is made of metal material and has a relatively heavy texture. The effective contact between the covering box 1 and the autoclaved aerated concrete board can be ensured by relying on the self-gravity of the device.

[0045] During operation, place the device on the autoclaved aerated concrete board to be processed, start the drive motor 18. The drive motor 18 drives the assembly plate 5 to rotate, causing the first serrated plate 7 to rotate. Rotate the adjusting threaded rod 14 to make the first serrated plate 7 continuously approach the autoclaved aerated concrete board to be processed until pull pores corresponding to the set roughening depth are punched on the surface of the autoclaved aerated concrete board to be processed. Hold the handle and move the covering box 1. After punching a number of pull pores on the surface of the autoclaved aerated concrete board to be processed and dividing the surface of the autoclaved aerated concrete board to be processed into several sections of areas to be roughened, stop the rotation of the drive motor 18. Observe through the transparent observation window whether the assembly plate 5 is in the state where the top hole 12 is horizontally upward. If so, start the telescopic rod 20; otherwise, start the drive motor 18. After adjusting the assembly plate 5 to the state where the top hole 12 is horizontally upward, start the telescopic rod 20 again. Control the telescopic rod 20 to contract, so that the linkage plate 21 drives the insertion rod 22 to insert into the top hole 12 and squeeze the second serrated plate 10, as shown in the attachment Figure 5 shown, until the second serrated plate 10 is squeezed and fitted into the pull pores, stop the telescopic movement of the telescopic rod 20, pull the handle, and drive the covering box 1 to move, then thorough roughening treatment can be carried out on the autoclaved aerated concrete to be processed.
