Description

[Technical Field]

[0001] The present invention relates to a novel method for mounting and fixing an inverter and an installation mechanism used therefor. [Background technology]

[0002] Inverters are heavy, so when installing them on a wall, rails are laid on the ground, the inverter is placed on a cart, an installation frame is attached to the backside, and the cart is then transported to the installation site. The cart is then secured to the front with fasteners, and the installation frame is then fixed to the wall. Therefore, when replacing an inverter, a cart must be inserted to support the bottom of the inverter, the installation frame must be removed from the wall, and the cart must be carried out. Meanwhile, outdoor units for large air conditioning systems in buildings and factories are installed on rooftop platforms. Installing heavy objects such as air conditioning system outdoor units on rooftops requires moving the heavy object horizontally on the platform and then setting it in a designated position above or below the platform. This requires a lot of materials, manpower, and labor, and poses the risk of workers falling from the platform. Therefore, a bearing roller transport system has been proposed that allows heavy objects to be transported on platforms at low cost, quickly, and safely (Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-074188 Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, in consideration of the conventional method of replacing heavy objects, the present invention aims to provide an inverter mounting and fixing method and mechanism that uses an inverter hanging mechanism and a slide mechanism to replace the above-mentioned conventional replacement work using an inverter cart, and that makes it easy to deliver and mount the inverter to a designated location, and to remove and take it out from the designated location. [Means for solving the problem]

[0005] The present invention is a method for suspending a heavy inverter IV in an inverter placement room equipped with an installation frame W located on the rear wall, and pushing the inverter IV from the front toward the rear via a slide mechanism to mount and fix it to the installation frame W on the rear wall, wherein the horizontal slide mechanism 100 for sliding horizontally comprises an anchor part A extending in the direction of pushing the inverter IV toward the rear of the inverter placement room and comprising a pair of fixed rails 110 arranged opposite to each other, and an extendable slide frame body B mounted to the pair of fixed anchor rails 110 of the anchor part A so as to be slidable in the longitudinal direction, The telescopic slide frame B is slidably mounted on the fixed anchor rail 110 of the anchor portion A. The inverter IV is constructed of an intermediate hanger section 120 to be mounted and a slide section 130 consisting of a slide rail that is mounted integrally with or slidably inside the intermediate hanger section 120, and preferably the slide section 130 has a pair of slide rails 131, 131 reinforced with parallel angle members 132, 132 perpendicular to the slide rails to provide the strength to suspend the inverter IV, and the method for installing a heavy inverter is characterized in that: 1) the inverter IV is lifted up by a suspension mechanism 200 via a suspension band 201 and attached to the slide section 130 in a suspended state; 2) the slide section 130 with the inverter IV suspended is pushed into the intermediate hanger section 120 (first movement); 3) the intermediate hanger section 120 with the slide section 130 pushed in is then pushed to the back of the inverter placement room via the fixed anchor rail 110 (second movement); and 4) the inverter IV is mounted and fixed to the installation frame W. The first movement and the second movement may be performed integrally (see FIG. 3). [Effects of the Invention]

[0006] According to the present invention, a heavy inverter can be hung, pushed into the inverter placement room, and attached to the mounting frame on the back wall while hanging, making the installation work extremely simple compared to the method of mounting on a cart.

[0007] The present invention only requires the use of a hanging mechanism and a slide mechanism, and can be implemented by the following device. That is, a lifting mechanism 200 that lifts and lowers the inverter IV via a hanging belt is made up of a hanging band 201 and an elevator 202, and a slide mechanism 100 is provided that pushes the inverter IV suspended via the lifting mechanism 200 from the front to the back of the inverter placement chamber while suspended. The lifting mechanism 200 includes a hanging band 201 and an elevator 202 that raises and lowers the hanging band 201. Meanwhile, the slide mechanism 100 is disposed within the inverter placement chamber, extending in the direction of pushing it back. The slide mechanism 100 comprises a pair of fixed anchor parts 110 arranged opposite to each other, an intermediate hanger part 120 having a pair of hanger rails 121 slidably mounted in the longitudinal direction on the anchor rails 111 of the fixed anchor parts 110, and a slide part 130 comprising a pair of slide rails 131 slidably mounted, preferably integrally (see FIG. 3 ), in the longitudinal direction on the intermediate part 120. Preferably, the intermediate hanger part 120 has a plurality of parallel engagement parts 121, 122 extending in the longitudinal direction on the front and back, with the outer engagement parts 121 fitted into the ridge parts 111 extending in the longitudinal direction of the fixed rails 110 and the inner engagement parts 122 fitted into the ridge parts 131 extending in the longitudinal direction of the slide part 130. Then, the inverter IV is lifted to a predetermined height by the lifting band 201 of the lifting device 200, and in this state, the inverter IV is engaged with the hanging plate 203 provided on the upper side of the inverter IV and the hanging hook 133 provided on the hanging angle 132 at the bottom of the slide section 130, thereby forming a heavy inverter mounting device.

The extendable sliding frame B includes a first sliding section 120 that is slidably mounted on the fixed rails 110 of the hanger section A, and a second sliding section 130 that is slidably mounted inside the first sliding section 120. The second slide section 130 has a pair of slide rails 131, 131 reinforced by parallel angle members 132, 132 perpendicular thereto, providing the strength to hang the inverter IV. That is, the slide mechanisms 100 arranged on both sides of the inverter placement chamber extending in the direction of pushing the inverter into the interior are made up of a pair of fixed rail sections 110 arranged opposite to each other, a hanger section A, an intermediate hanger section 120 made up of a pair of hanger rails attached to the fixed rails 110 so as to be slidable in the longitudinal direction, and a slide section 130 made up of a pair of slide rails 131 attached to the hanger section 120 so as to be slidable in the longitudinal direction. The intermediate hanger portion 120 has a plurality of parallel engagement portions 121, 122 extending longitudinally on the front and back, the outer engagement portion 121 of which is fitted into the convex rib portion 111 extending longitudinally of the fixed anchor portion 110, while the inner engagement portion 121 of which is fitted into the convex rib portion 131 extending longitudinally of the slide portion 110, and the inverter IV is lifted to a predetermined height by the hanging belt 201 of the lifting device 200, and in that state the inverter IV is engaged with the hanging plate 204 provided on the upper side of the inverter IV and the hanging hook 133 provided on the hanging angle 132 at the bottom of the slide rail portion 130.

[0010] As shown in Figure 2, the intermediate hanger portion 120 has multiple parallel engagement portions 121, 122 extending longitudinally on the front and back, and the outer engagement portion 121 is fitted into the protruding portion 111 extending longitudinally of the fixed anchor portion 110, while the inner engagement portion 122 is fitted into the protruding portion 111 extending longitudinally of the slide portion 130.

[0011] In particular, as shown in Fig. 1, the intermediate hanger section 120 and the slide section 130 form a hollow frame that is expandable and contractible in the sliding direction, and it is preferable that the hanging belt 201 can be inserted upward and that the opposing hanging angles 132 of the slide rail section 130 are reinforced. Note that, as shown in Fig. 3, the intermediate hanger section 120 and the slide section 130 can be integrated, and a hanging frame reinforced with hanging angles 132 can be slidably attached to this, and the pair of opposing hanging angles 132 can be configured to be joined by a cross member 133, so that the first movement and the second movement can be pushed inward without distinguishing between them.

[0012] (Installation process) According to the present invention, in an inverter placement room having a mounting frame W located on the rear wall, a heavy inverter IV is suspended and pushed into the rear of the inverter IV from the front via a slide mechanism to be attached and fixed to the mounting frame W on the rear wall. 1) In the first step (hanging the inverter), as shown in FIG. 1(1), a hanging band 201 is hung from the bottom of the inverter IV, passed around the top, and connected to a hanging belt 203 of an elevator 202 attached to the ceiling, and then lifted to a predetermined position using a remote control (not shown) (see FIG. 1(2) and FIG. 4). 2) Next, as shown in FIG. 5, the hanging plate 204 provided on the side of the inverter IV is engaged with the hanging hook 133 of the hanging angle 131 of the slide rail portion 130 (FIG. 1(3) and FIG. 5). 3) Then, as shown in FIG. 6, the inverter IV is balanced using the hanging hook and hanging belt, and the slide rail part 130 is pushed into the hanger rail part 120 (first movement: see FIG. 1(4)). 4) Thereafter, as shown in FIG. 7, while the sliding portion 130 is pushed in, it is pushed into the fixed anchor 110 together with the hanger portion 120 (second movement: see FIG. 1(5)). 5) Then, screw the back of the inverter IV to the mounting frame W to secure it in place.

[0013] According to the above embodiment, the slide mechanism 100 is arranged to extend in the direction of pushing the inverter into the interior of the inverter placement chamber, and comprises a pair of fixed rail portions 110, a hanger portion 120 slidably attached to the fixed rails in the longitudinal direction, and a slide portion 130 slidably attached to the hanger portion 120 in the longitudinal direction, so that the inverter can be smoothly replaced in a suspended state without using a dolly. While a representative example of the slide mechanism 100 is shown in Figure 2, it is not limited to this. Aside from the essential requirement that the fixed anchor portion A and the extendable slide frame B have the strength to suspend and slide a heavy load, those skilled in the art can make various modifications to the slide mechanism without departing from the spirit and scope of the present invention, such as forming the slide portion 130 and the hanger portion 120 into an integral structure to form a suspension mechanism, instead of slidably attaching them to each other.
