Description

  The present invention can be changed to a movable floor pool without remodeling an existing fixed floor pool, and a cylinder having two or more stages necessary for a short construction period without remodeling an existing pool. The present invention relates to an elevating pool apparatus including the apparatus.

  The conventional elevating pool apparatus is, for example, a pantograph type elevating apparatus provided on the lower surface of the movable floor as shown in Patent Document 1, or an elevating apparatus provided on the lower surface of the movable floor as shown in Patent Document 2 Many proposals have been made, such as moving the device up and down by rotating the screw shaft.

Japanese Patent No. 2566122 JP 2004-116243 A

  However, in the system shown in Patent Document 1, since one of the links serves as a sliding end with respect to both the fixed floor and the movable floor, it is difficult to handle when the floor surface is tilted. In general, the pool has a slope on the floor because of drainage, so it has a problem that it is difficult to install in the existing pool.

  Furthermore, since the system of Patent Document 2 is a screw shaft drive source and a motor is arranged, construction of the pool side wall is necessary to apply to an existing pool, and it is provided at a plurality of locations. In order to drive the lifting device with a single screw shaft, each lifting device and the screw shaft have to be accurately arranged.

  In addition, as a multistage cylinder device used in the above conventional lifting pool device, a single stroke cylinder is overlapped in series to form a double stroke, or a rod of a single stroke cylinder is clamped at an intermediate stop position. Or a one-stage stroke cylinder combined in a nested manner to form a two-stage stroke is known.

  Among these prior arts, the one-stage stroke type cylinders that are overlapped in series to form a two-stage stroke have the problem that the cylinder height increases because the cylinders are connected in series, Clamping the rod of a single-stroke cylinder at an intermediate stop position requires special control and additional mechanisms such as balancing the pressure applied to the cylinder and requiring sensors, etc. There was a problem of high cost.

  Further, the one-stage stroke type cylinder is combined into a nested type to form a two-stage stroke, which is composed of a first flange on the piston rod side, a second flange, a first flange on the head side, a second flange, and four flanges. Therefore, there was a problem that the height was increased.

  As described above, the conventional multistage cylinder device has a problem in that when the cylinder is installed in an existing pool, the water depth of the pool after installation has changed greatly due to the high height of the cylinder.

  The present invention was devised in view of the current situation, and the object of the present invention is to arrange the mechanism for holding the floor on the back side of the movable floor, so that the rigidity of the movable floor can be relatively low. The movable floor is lighter, making the work easier, and connecting each jack unit with a fluid pressure circuit, so the relative position between the jacks does not need to be so precise, making the work easier and the jack unit Because it is driven by a high degree of freedom in the location where the drive source (fluid pressure pump) is placed, it is not necessary to place it on the pool wall surface, so construction of the pool wall surface is unnecessary, and a portable drive source is used. If configured, a dedicated machine room becomes unnecessary and the height of the mechanism part can be lowered, so it is not necessary to change the water depth of the existing pool greatly, regardless of the height of the movable floor, Since the relationship between the Linda unit and the piping does not change, the piping configuration can be simplified, and the configuration of the jack unit remains the same. If multiple stages of hydraulic cylinders are used, the stop position of the movable floor can be set to multiple stages. As the end of the jack unit does not slide with respect to the pool fixed floor, the liftable pool apparatus is equipped with a cylinder device having a required number of two or more stages that can be easily applied to a fixed floor with a slope for drainage. Is to provide.

  In order to achieve the above object, in the elevating pool apparatus according to claim 1, the pool movable floor supported by the jack unit on the pool fixed floor, the jack unit comprising a cylinder unit and a movable floor fixed A plate, a pair of left and right cylinder arms, a pair of left and right movable floor side arms, a pair of left and right fixed floor side arms, and a fixed floor side fixed plate. Fluid pressure piping is connected in communication, and the cylinder unit is configured to be slidable while maintaining an airtight state in the vertical direction, and the sliding operation of each cylinder is controlled by a working fluid via an electromagnetic valve. The vertical drive control of each cylinder is configured to be controllable by a control circuit. .

  According to a second aspect of the present invention, the elevating pool device according to the first aspect is technically premised, and the cylinder unit is extended from the most contracted state to an intermediate position and the most extended. It is composed of a two-stage cylinder unit that stops at three positions.

  Furthermore, the invention according to claim 3 is based on the technical premise of the elevating pool device according to claim 1, and the cylinder unit is composed of a multistage cylinder unit having three or more stages. To do.

  As described above, in the elevating pool device according to the present invention, since the mechanism for holding the floor is disposed on the back side of the movable floor, the rigidity of the movable floor can be relatively low, and thus the movable floor is lightweight. Therefore, it is easy to work, and each jack unit is connected with a fluid pressure circuit, so there is no need to make the relative position of the jacks so accurate, the work is facilitated, and the jack unit is driven by fluid pressure. Therefore, since there is a high degree of freedom in the position to place the drive source (fluid pressure pump), it is not necessary to place it on the pool wall surface, etc., so construction of the pool wall becomes unnecessary, and if it is configured using a portable drive source, A dedicated machine room is not required, and the height of the mechanism can be lowered, so that the water depth of the existing pool does not have to be changed greatly, and the cylinder unit can be installed at any height. The piping configuration can be simplified, the jack unit configuration remains the same, and if multiple stages of hydraulic cylinders are used, the movable floor stop position can be set to multiple stages. Since the end of the jack unit does not slide with respect to the pool fixed floor, there are a number of excellent effects such as easy compatibility with a fixed floor with a slope for drainage.
