Description
Technical Field
[0001] The utility model relates to the field of grinding of concrete components, and specifically relates to a sander for precast concrete components. Background Art
[0002] With the continuous progress of society, green prefabricated buildings have also begun to develop and spread continuously. Prefabricated buildings are a new type of building method, in which building components are prefabricated in a factory and then transported to the construction site for assembly. Compared with the traditional building method, this method has many advantages:
[0003] 1. Shorten the construction period: Since many components are prefabricated in the factory, the on-site construction time is greatly shortened, which can effectively improve the project efficiency;
[0004] 2. Improve the quality: The production environment in the factory is more controllable, which is conducive to ensuring the quality of components and reducing quality problems caused by factors such as weather during on-site construction;
[0005] 3. Reduce labor costs: Prefabricated buildings usually require less on-site labor, which can effectively cope with the shortage of labor;
[0006] 4. Environmental protection and energy conservation: Prefabricated buildings produce less waste during production and construction, and also help to reduce energy consumption during the construction process.
[0007] 5. Flexibility: Prefabricated buildings can be modularly designed according to needs, and are easy to expand or transform.
[0008] In practical applications, prefabricated buildings have achieved success in many fields such as residential, commercial buildings and public facilities; with the development of technology and market demand, prefabricated buildings are expected to be more widely used in the future.
[0009] Prefabricated concrete components are made in a prefabricated building factory according to design requirements, including precast walls, slabs, beams, etc., and then transported to the construction site for assembly. However, since these precast concrete components are directly assembled and used at the construction site, before they are prefabricated and leave the factory, it is necessary to detect the appearance quality of the concrete components to be used.

The current methods for grinding these precast concrete components with certain defects are basically manual grinding with a grinding wheel. This traditional manual grinding method not only has low efficiency, but also is very unsafe and prone to accidents. Content of the Utility Model

[0031] Such as Figures 1 to 2As shown in the figure, a sanding machine for precast concrete components is used to sand and polish precast concrete components instead of manual labor.

[0032] Further, in the embodiment, a rotating shaft is arranged through the sanding roller 2. One end of the rotating shaft is fixedly connected to the sanding roller 2, and the other end of the rotating shaft passes through the connecting plate rotatably through a bearing and the end is connected with a driving mechanism. The driving mechanism drives the sanding roller 2 to rotate through the rotating shaft, and the connecting plate is fixedly connected to the sanding machine frame 1.

The protective cylinder cover 21 is provided with a number of blind holes for the residue of the precast concrete components to fall; an opening is provided on one side of the protective cylinder cover 21 close to the precast concrete components to be sanded and polished. The opening provided on the protective cylinder cover 21 is used for the sanding roller 2 to contact the surface of the precast concrete components; the protective cylinder cover 21 is connected to the limiting mechanism. By controlling the driving mechanism to drive the sanding roller 2 in the protective cylinder cover 21 to rotate; at the same time, the precast concrete components to be sanded and polished are limited in the limiting mechanism, and then by adjusting and controlling the limiting mechanism to drive the precast concrete components to contact the sanding roller 2, the surface of the precast concrete components is sanded and polished by the rotation of the sanding roller 2.
[0033] Further, in the embodiment, the limiting mechanism includes a first limiting plate 3; a notch for the precast concrete member to contact with the sanding roller is formed in the first limiting plate 3, and the notch is communicated with the opening formed in the protective cylinder cover 21. The protective cylinder cover 21 is connected to the first limiting plate 3, and the first limiting plate 3 is fixed on the sanding machine frame 1; second limiting plates 4 for movably limiting the precast concrete member are respectively arranged on both sides of the first limiting plate 3; movable structures for placing the precast concrete member are movably installed on the end faces of the second limiting plates 4 close to the first limiting plate 3. Moreover, each of the movable structures includes a movable support block 41, and the movable support block 41 is arranged to be capable of lifting and sliding on the lower part of the end face of the second limiting plate 4 close to the first limiting plate 3; a limiting bolt penetrates through the movable support block 41, and the movable support block 41 is movably limited to the second limiting plate 4 through the limiting bolt. In addition, movable screws are rotatably penetrated through the upper and lower parts of the second limiting plate 4, one end of each movable screw can movably pass through the second limiting plate 4, and the other end of each movable screw is connected with a movable rotation handle 42 for conveniently driving the movable screw to rotate.
[0034] With such a design, when the precast concrete member needs to be sanded, the precast concrete member is placed on the movable support blocks 41 on the two second limiting plates 4, and then the position height of the movable support block 41 is adjusted to make the precast concrete member in a suitable position on the second limiting plate 4. Then, the movable rotation handle 42 is used to drive the movable screw to rotate, and the second limiting plates 4 connected to each side of the movable screw are respectively driven to move towards one end of the first limiting plate 3, so as to limit the precast concrete member between the first limiting plate 3 and the second limiting plate 4; then, the driving mechanism drives the sanding roller 2 to rotate, and the precast concrete member in contact with the sanding roller 2 is sanded.

Furthermore, when it is necessary to start the sanding roller 2, the driving motor 5 is started by control. The driving motor 5 drives the driving wheel to rotate, and the driving wheel drives the transmission wheel connected through the belt to rotate through the belt. The driving wheel and the transmission wheel are arranged in the protective housing 6 through belt transmission, and the protective housing 6 plays a protective role; when the transmission wheel rotates, the sanding roller 2 is driven to rotate through the rotating shaft, so as to sand and polish the precast concrete member in contact with the surface of the sanding roller 2. It should be noted here that by controlling the relative distance between the second limiting plate 4 and the first limiting plate 3, the precast concrete members with different thicknesses can be limited, so that the sanding machine can sand and polish the precast concrete members with different thicknesses; and the relative distance between the second limiting plate 4 and the first limiting plate 3 can also be controlled to drive the "distance" between the surface of the precast concrete member placed and limited on the second limiting plate 4 and the surface of the sanding roller 2 to be in contact, so as to meet the depth requirement for sanding and polishing the surface of the precast concrete member, so as to meet the requirements of sanding and polishing.
