JPH0549122A - Both-sided lifter - Google Patents

Abstract

PURPOSE:To facilitate the carrying in and out of electric equipment even in the narrow passage between the switchboards arranged in opposition by enabling a pallet, which goes up and down being guided by a longitudinal frame, to rotate horizontally around the vertical frame. CONSTITUTION:A plurality of wheels 2 for traveling are attached to both ends and the center of a bottom frame 3 parallel with a floor face 1, whereby it becomes possible to shift freely on the bottom face 1. A vertical frame 4 is fixed to the center of the bottom frame 3. Joints 3C and 3D are provided on both ends of the base of the vertical frame 4, whereby it becomes possible to bend either half 3A or 3B of the bottom frame 3 vertically. Moreover, a lifting pallet 7 is provided along the vertical frame 4 by a hoisting unit 9, a guide roller 5, and pulleys 8A-8C. The pallet 7 is fixed in the position of A or B, being guided and slid in the horizontal direction by a load pallet guide 6. Hereby, the carriage of electric equipment and the carrying in and out into and out of a switchboard panel can be performed even in the narrow passage between the switchboards arranged in opposition.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a double-sided lifter used for pulling out electric equipment housed in switchboards arranged facing each other.

[0002]

2. Description of the Related Art FIG. 3 is a side view showing the structure of a conventional lifter, and FIG. 4 is a front view thereof. As shown in FIGS. 3 and 4, a conventional lifter has a vertical frame 4 vertically attached to an end of a rectangular bottom frame 11 which is parallel to the floor 1 and has wheels 2 for traveling on the floor at both ends. A loading platform 12 that is fixed and that is guided by the vertical frame 4 and moves up and down in the vertical direction is provided. The platform 12 is moved up and down by a hoisting device including a rope 10, pulleys 8A, 8B, 8C and a hoisting unit 9 including a handle and a gear device.

When the electric equipment housed in the switchboard is pulled out to the outside, the lifter is brought close to the front surface of the switchboard 13 or 13A, and the electric equipment is placed on the carrier 12 and carried out.

[0004]

In a recent electric room or the like, the switchboards are arranged so that the front faces face each other due to the limitation of the installation space, and the front face maintenance space is small, so that such a conventional lifter is used. When using it, the lifter had to be turned upside down in a small space to change the direction with respect to the switchboard arranged with the fronts facing each other, which was a very troublesome work.

Therefore, an object of the present invention is to provide a lifter which does not need to be inverted with respect to the front surface of the switchboard when the electric equipment housed in the switchboard arranged so that the front surfaces thereof face each other is pulled out to the outside. To provide the structure.

[0006]

In order to achieve the above-mentioned object, the present invention is a lifter used for pulling out electrical equipment housed in a switchboard to the outside, and having a rectangular shape parallel to the floor surface. A bottom frame, a rectangular vertical frame in which one end in the longitudinal direction is vertically fixed to the central portion in the longitudinal direction of the bottom frame, and a loading platform guide that is guided by the vertical frame and moves vertically along the vertical frame, The luggage carrier is guided by the luggage carrier guide, slides in the horizontal direction, passes through a vertical surface constituted by the vertical frame, and moves to both sides of the vertical frame. Further, the bottom frame is provided with joints for bending one half of the bottom frame upward from both sides of the fixed portion between the bottom frame and the vertical frame.

[0007]

According to the structure of the present invention, the loading platform on which the electric equipment is placed is guided by the vertical frame so that it can slide horizontally with respect to both sides of the vertical frame by sliding with respect to the vertical loading platform guide. When pulling out the electric equipment housed in the switchboard on the side opposite to the loading platform to the outside, the loading platform may be slid to the opposite side without inverting the lifter each time. Also, when moving the lifter backward while pulling out the electric device to the outside, the bottom frame on the rear side is bent upward so as not to interfere with the switchboard on the rear side.

[0008]

1 is a side view showing an embodiment of the present invention, and FIG. 2 is a front view thereof. In FIG. 1 and FIG. 2, one end of a rectangular vertical frame 4 which is parallel to the floor surface 1 and has a rectangular bottom frame 3 provided with wheels 2 for running the floor surface at both ends and a central part thereof is perpendicular to the central part. Is fixed to the vertical frame 4, and a loading platform guide 6 which is guided by guide rollers 5 and moves vertically is provided on the vertical frame 4. Further, there is provided a loading platform 7 which slides on the loading platform guide 6 and moves horizontally to both sides of the vertical frame 4 while passing through a vertical surface formed by the vertical frame 4. Although not shown, the loading platform 7 is shown in FIG.
When it is in the position A or B shown in, the headed pin is inserted into the loading platform 7 and the loading platform guide 6 to fix the position.

The loading platform guide 6 includes a pulley 8A provided on the loading platform guide 6 and pulleys 8B and 8C provided on the upper end of the vertical frame 4.
And one end is fixed to the upper end of the vertical frame 4 and the other end is the hoisting unit 9
The hoisting device is composed of the rope 10 connected to the.

Further, the bottom frame 3 is provided with joints 3C and 3D capable of bending one half 3A or 3B of the bottom frame 3 upward from both sides of the fixed portion between the bottom frame and the vertical frame 4, and the electric equipment is externally connected. When the lifter is moved backward while being pulled out, the rear bottom frame 3A or 3B is bent upward so as not to interfere with the rear switchboard. Although not shown, the bent bottom frame 3
The portion A or 3B is fixed by inserting a headed pin into the vertical frame 4.

[0011]

According to the present invention, the loading platform on which the electric equipment is mounted can be slid horizontally with respect to the loading platform guide and can be fixed by moving the loading platform guide to the switchboard side to be used with respect to the vertical frame. It is not necessary to invert the lifter each time the electric equipment housed in the arranged switchboard is pulled out, and workability in a narrow space is improved.
