Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to an assembled concrete prefabricated component roughening device. Background Art

[0002] In recent years, prefabricated buildings have shown a good development trend. Prefabricated small components such as composite panels, air conditioning panels, balcony panels, and road panels account for a large proportion. These components have the characteristics of uniform specifications, large prefabrication quantity, and small volume, which are convenient for rapid prefabrication and large-scale production in factories. Before the production of prefabricated concrete components, the concrete surface needs to be roughened according to the specifications. That is, after the concrete is slurried and smoothed, the surface is roughened with tooling. The roughening depth is controlled at 1 to 2 mm. The construction process should be completed once and no stops are allowed. After the roughened concrete solidifies, the scum is removed. After the molding is completed, the groove depth and width should be uniform, and the appearance texture should be smooth and beautiful.

[0003] Before roughening a prefabricated component, the roughening knife needs to be retracted and extended according to the size of the prefabricated component in order to adjust the roughening gap and the roughening coverage area. At present, the retraction and extension process of the roughening knife generally requires manual adjustment, has a low degree of automation, and is not very convenient to use.

[0021] A tool rod 9 is arranged side by side below the linear slide 4, and both ends of the tool rod 9 are connected to the corresponding slider 6. A plurality of rotatable tool sleeves 10 are arranged at intervals on the tool rod 9. A roughening knife 11 is fixed to the bottom of the tool sleeve 10, and a V-shaped fork 12 is fixed to the top of the tool sleeve 10. The lateral opening connecting line of each V-shaped fork 12 is parallel to the axis of the tool rod 9, and each V-shaped fork 12 cooperates with the rotating toggle device 5.

[0022] A spring top bead 13 is arranged in front of the roughening knife 11, and a knife blocking rod 14 is arranged at the rear. The spring top bead 13 is fixed on the knife sleeve 10, and a positioning groove 15 for positioning and cooperating with the spring top bead 13 is arranged on the outer wall of the knife rod 9; the knife blocking rod 14 is arranged side by side with the knife rod 9, and the knife blocking rod 14 is connected to the knife rod 9 through a knife blocking frame 16.

[0023] In this embodiment, the lifting unit 8 includes a first drive motor 801, which is installed on the top of the self-propelled portal frame 3. A screw rod 802 is provided at the output end of the first drive motor 801, and the screw rod 802 is connected to the reserved threaded hole on the slider 6.

[0024] In this embodiment, the rotary shifting device 5 includes a second drive motor 501, and the power output shaft of the second drive motor 501 is provided with a shifting rod 502, the lower end of the shifting rod 502 extends into the V-shaped fork 12, and the lower end of the shifting rod 502 cooperates with the V-shaped fork 12.

[0025] In this embodiment, the self-propelled gantry frame 3 includes a gantry frame body 301, and roller groups 302 rolling along the track 2 are arranged on both sides of the gantry frame body 301. A third drive motor 303 is arranged on the gantry frame body 301, and the third drive motor 303 is connected to the drive shaft 304 through a chain assembly.

Figures 1 to 4 As shown, the action process of the utility model is as follows:

[0026] The precast concrete component 17 is placed on the precast formwork bracket 1, and the roughening knife 11 is retracted and extended according to the width of the precast concrete component 17, so as to adjust the gap between the roughenings 11 and the coverage area of ​​the roughenings. Specifically, the length, width and height of the precast concrete component 17 are input into the controller, and the controller controls the action part of the linear slide 4 to move left or right according to the previously pre-written program. When the linear slide 4 drives the lever 502 of the rotating toggle device 5 to move into the notch of the V-shaped fork 12, the controller controls the second drive motor 501 of the rotating toggle device 5 to drive the lever 502 to rotate counterclockwise or clockwise. The lever 502 will toggle the V-shaped fork 12 and the knife sleeve 10 to rotate clockwise or counterclockwise during the rotation process. The knife sleeve 10 will retract or lower the roughening knife 11 during the rotation process. When the roughening knife 11 is retracted, the spring top bead 13 is embedded in the corresponding positioning groove 15, thereby temporarily fixing the roughening knife 11; when the roughening knife 11 is lowered, the rear part of the roughening knife 11 is against the knife blocking rod 14, and the roughening knife 11 is basically in a vertical state. Repeat the above operation to retract and release each roughening knife 11 in turn.

[0027] After the gap between the roughening knives 11 (the roughening knives are retracted and extended) is determined, the controller adjusts the height of the knife rod 9 according to the height of the precast concrete component 17 to control the roughening depth of the lowered roughening knives 11.

[0028] It should be noted that the linear slide 4 is an existing module, and its structure is not described in detail. The control program output from the controller can be programmed by a dedicated programmer.

[0029] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
