Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a floor polishing apparatus.

[Prior Art]

 In this type of floor refining device, a water tank, a motor, a transmission, and a refining head are conventionally mounted on the chassis, and the motor is rigidly fixed to the chassis at this time, and can be freely removed by the user. It wasn't like that. In addition, the nozzle structure was such that a large number of injection holes having a relatively large cross-sectional area were formed around the periphery of the nozzle by a known method so that a relatively large amount of water could be injected. When the amount of water was large, no dust was generated during the floor smelting work, but the sprayed water often penetrated from the concrete surface into the concrete, leading to deterioration of the concrete structure. Moreover, when polishing without passing water, a large amount of dust was generated during the floor polishing work.

[Problems to be solved by the device]

 The problem to be solved is that the floor refining equipment can perform the floor refining more safely without generating dust or deteriorating the concrete structure due to the use of a large amount of water. It is to create a training device.

[Means for Solving the Problems]

 An object of the present invention is to mount a water tank, a motor equipped with an electric control device for controlling the rotation speed, and a polishing head on a chassis in a floor polishing apparatus, and the motor can be easily removed. Yes, and the smelting head is fixed to the water shaft via a coupling, and the smelting head is interchangeably fitted with nozzles of various types with small diameter injection holes. Will be solved.

【Example】

 1 and 2, a floor refining apparatus according to the present invention has a chassis 1, a handle 2 and casters 3 mounted on the chassis 1, and a water tank 4 on the chassis 1 and a control for varying the number of revolutions. A motor 6 provided with a device is arranged, and another pulley 9 is rotationally driven from a motor pulley 7 via a drive belt 8, and the other pulley 9 is rotatably supported by a bearing 11 fixed on the chassis 1. It is fixed on the water passage shaft 10. The motor 6 can be fixed to the chassis 1 by a bolt (not shown), so that only the motor 6 can be easily removed from the chassis 1 by loosening the bolt. A water passage hole 10a is provided at the center of the water passage shaft 10, and a water supply pipe 5 is inserted into the water passage hole 10a. The water passage hole 10a can move relative to the water supply pipe 5 without making contact. Following the hole 10a at the center of the water passage shaft, a hole 10b having a smaller diameter than this hole is formed. An elastic coupling 12 is fixed to the lower surface of the chassis 1 in the range of the lower end of the water shaft 10 protruding from the bearing 11, and a diamond wheel 13 for polishing is provided together with the nozzle 14 through the elastic coupling 12. It is fixed. As nozzles, various types of nozzles are provided as shown in FIGS. These nozzles 14a-14g can be replaceably attached to the coupling 12. The nozzles 14a to 14g shown in FIGS. 3 to 16 have a hexagonal head in common, a male screw m on the outer diameter, and a vertical hole n passing through the center of the nozzle and the vertical hole n. And an orifice o directed in the radial direction that forms the injection hole of the nozzle. In the nozzle 14a according to FIGS. 3 and 4, only one orifice o is provided. In the case shown, the orifice o is oriented perpendicularly to the longitudinal axis of the nozzle, but it is not limited to being vertical and it can be tilted slightly upward or downward with respect to the illustrated orifice o. Similarly, in the nozzle 14b according to FIGS. 5 and 6, there is only one orifice o, but the orifice o is not directly formed in the head of the nozzle but is provided in the plug p, and the plug p is screwed into the head. Has been. The one provided with the plug p can be applied not only to the embodiment according to FIGS. 5 and 6 but also to the embodiments from FIGS. 7 to 12 described below. The nozzle 14c shown in FIGS. 7 and 8 is provided with two orifices o as injection holes. In the case shown, the orifice o is oriented perpendicular to the longitudinal axis of the nozzle, but it can be tilted slightly upwards or downwards with respect to the illustrated orifice o. The nozzle 14d shown in FIGS. 9 and 10 is provided with three orifices o forming injection holes. In the case shown, the orifice o is tilted slightly downwards with respect to the longitudinal axis of the nozzle, but it can be tilted perpendicularly or slightly upwards with respect to the longitudinal axis of the nozzle. The nozzle 14e shown in FIGS. 11 and 12 is provided with four orifices o which form injection holes. The orifice o is tilted slightly upward with respect to the longitudinal axis of the nozzle, but can be tilted perpendicularly with respect to the longitudinal axis or slightly downward. In the nozzle 14f according to FIGS. 13 and 14, six nozzles are provided and the orifice o is provided in the plug q as an adapter. In the case shown, the orifice o is oriented perpendicular to the longitudinal axis of the nozzle, but it can also be tilted slightly upwards or slightly downwards. The nozzle 14g shown in FIGS. 15 and 16 has only one orifice o as an injection hole and is provided in the plug r as an adapter. The water shaft 10 is driven via the drive belt, whereby the diamond wheel 13 is rotated and the floor can be ground by the edge 13a provided with the diamond. When the cross section of the orifice o is circular, the diameter of the orifice o is selected in the range of 0.1 to 3 mm. In this case, the criterion for selection is to meet the condition of the concrete surface, which is the surface to be processed, and the water flow rate. The amount of water is extremely small, and in a state of water supply from the water supply pipe 5, the water is only dripping from the tip of the orifice o, and the water is set to be tangentially scattered by the centrifugal force generated by the rotation of the diamond wheel 13. As a result, suitable training is performed. When the cross section of the orifice o is rectangular, the slit width can be appropriately selected within the range of 0.1 to 3 mm. Suitable materials for the nozzle are stainless steel, brass, aluminum alloy and the like.

[Effect of the device]

 According to the present invention, since the motor can be easily attached to and detached from the chassis, the motor can be removed to remove the floor polishing device when there is no lifting device for the floor polishing device at the construction site. Can be made lighter and can be transported. Further, since the rotation speed of the motor can be continuously changed by the control device, the floor polishing apparatus can be applied to the polishing of floor surfaces under various different conditions. The amount of water flowing from the nozzle is so small that it drips, and because it is only scattered by centrifugal force, there is no inconvenience of seeping into the interior from the concrete surface and the generation of dust can be completely suppressed. Optimal working conditions can be met by preparing various types of nozzles.
