2. Description of the Related Art Conventionally, as a generally known suspension apparatus for transporting an electrode plate, there is a technique disclosed in Japanese Utility Model Publication No. 2-10123 filed by the present applicant. It is used for loading and unloading of electrode plates to and from an electrolytic cell in an electrolytic smelting facility.

[0003]

In the above-mentioned electrode plate transporting suspension apparatus, an anode plate and a cathode plate as electrode plates are exchanged for a fixed period by using a ceiling crane. Signal the positioning of the suspension device to the operator of the overhead crane near the electrolytic cell, stop the suspension device at a predetermined position in the electrolytic cell, and attach a slinger who engages the hook with the anode plate or the cathode plate to the ceiling. Needed separately from the crane operator. Moreover, since the work of the slinger involves fine adjustment of the positions of the suspension device and the electrode plate so that the electrode plate is engaged with the hook when the electrode plate is carried out of the electrolytic cell, the work is performed manually. I had to be a skilled person. Further, in the position fine adjustment work of the slinger, the suspension device swings during the adjustment, and the electrode plate falls off, or the worker swings the electrode plate between the electrode plates due to the swing of the suspension device. There was always a danger, such as holding hands, and there was a problem with safety.

Accordingly, the present invention solves the above-mentioned problems of the conventional apparatus, and does not require a slinger, and suppresses the swing of the suspension for transporting the electrode plate when loading and unloading the electrode plate. Electrode plate transport that can be positioned at a predetermined position in an electrode plate storage place such as an electrolytic cell, and can prevent accidents such as dropping of the electrode plate, which is highly safe and enables automation of electrode plate replacement work. It is an object of the present invention to provide an elevating guide device for a suspension device for a vehicle.

[0005]

In order to achieve the above object, an invention according to claim 1 is characterized in that when an electrode plate is carried into and out of an electrode plate yard, an electrode plate is laid by an overhead crane. A guide device for guiding the lifting and lowering of the electrode plate transporting suspension device carried above the electrode plate storage space, and one side and the side portion of the electrode plate transporting suspension device. A guide member protruding outward on the other side substantially opposite to the other, and a guide frame erected on the electrode plate storage area and engaged with these guide members to guide the lifting and lowering of the electrode plate transport suspension device. And These guide frames are configured such that a guide member is movably engaged with an inner surface thereof, and an upper end portion is formed in an expanded portion which is tapered outward and upward. The invention of Claim 2 is Claim 1
In the invention of the above, the suspension device for transporting the electrode plate is formed in a rectangular shape in plan view, and overhanging pieces are fixed to both side portions of the suspension device, and guide members are provided at both end portions of these overhanging pieces. It is protruding. According to a third aspect of the present invention, in the first or second aspect of the present invention, the guide frames are formed in a substantially L-shape in cross section, and the same number of guide frames are erected on the electrode plate storage space corresponding to the guide members, and the inner surface angles of these guide frames The guide member engages with the portion.

[0006]

As described above, when the electrode plate is exchanged, the electrode plate transporting suspension device is moved by the guide members projecting from one side and the other side engaging with the inner surface of the guide frame. As a result, the swing is suppressed, the ascent and descent are guided, and the electrode plate is positioned at a predetermined position in the electrode plate place. Therefore, not only the swing of the device but also the swing of the electrode plate are almost eliminated.

Is a chain conveyor for transporting electrode plates as an electrode plate storage area
When the electrode plates are carried into and out of the chain conveyor 2, they are transported above the chain conveyor 2 by an overhead crane (not shown), and are vertically moved between the chain conveyor 2 and the chain conveyor 2 by the overhead crane. It is designed to be raised and lowered in the direction. The chain conveyor 2 is arranged at a position where the electrode plate received from the suspension device A and transported thereon is transported to an electrode plate stripper (not shown). Reference numeral 3 denotes a main body of the frame body 1, which is formed in a rectangular shape in plan view, and has, on both sides of the main body, the same direction as an electrode plate 4 (a cathode plate is illustrated in the drawings) mounted on a conveyor 2. The overhanging protruding piece 5 is fixed. Guide rollers 6 serving as guide members are provided on both end sides of the overhanging piece 5 so as to be rotatable outward at a predetermined angle θ. Various angles are assumed as the mounting angle θ of the guide roller 6, but 45 ° as shown in the figure is particularly preferable because engagement with the guide frame described later is smooth and reliable. In this example, the guide roller 6 is attached by pins 8 between a pair of attachment pieces 7 fixed to the lower surfaces of both end portions of the overhanging piece 5 as shown in FIG.

Reference numeral 10 denotes a hanging bracket for an overhead crane.
Upper frame installed at a predetermined interval on a pair of upper surfaces
11 is provided on. An electrode plate (cathode plate) hook 13 is attached to the frame body 1 so as to be pivotable by approximately 90 ° at a position in the same direction as the direction of the electrode plate 4 and at a position substantially orthogonal to the position. An operating cylinder 16 for turning via a slide shaft 14, an arm 15, and the like is provided so that the electrode plate 4 can be suspended or the like as the electrode plate transporting suspension device A moves up and down. Is substantially the same as in the prior art, and will not be described in detail.

Reference numeral 20 denotes a guide frame which engages with the guide roller 6 to guide the frame 1 up and down, and stands around the chain conveyor 2 in a number corresponding to the guide roller 6 (four in this embodiment). It is attached to the attached attachment frame 21. In FIG. 3, a connecting member 22 connects the upper end of the mounting frame 21. The lower end of the mounting frame 21 is a base frame.
Fixed to 23. These guide frames 20 are shown in FIG.
As shown in FIGS. 3A and 3B, the guide roller 6 is bent so as to have a substantially L-shaped cross section, and the guide roller 6 is engaged with the bent inner surface corner 25. The upper end portion of the guide frame 20 is formed in an expanded portion 26 which expands outward and in a tapered shape, and an electrode plate transport suspension device A which swings back and forth and right and left at a position above the chain conveyor 2 is provided. Even if the guide frame 20 is slightly displaced from the position of the guide frame 20 when descending, the guide roller 6 can be reliably engaged with the corner 25 of the guide frame 20 by being received by the expanding portion 26.

In the apparatus of this embodiment, a suspension apparatus A for transporting an electrode plate is suspended by a ceiling crane via a suspension fitting 10 provided on the frame 1 while maintaining a substantially horizontal position. The electrode plate 4 suspended by the hook 13 provided on the frame 1 of the plate transporting suspension device A is connected to the chain conveyor 2.
In order to temporarily place it on the upper side, the electrode plate transporting suspending device A is lowered at a predetermined position above the chain conveyor 2. When the electrode plate 4 is placed on the upper portion of the chain conveyor 2 as shown in FIG. 3, the hook 13 is turned by approximately 90 ° by the cylinder 16 to remove the hook 13 from the electrode plate 4.
Thereafter, the suspension device A for transporting the electrode plate is lifted and raised again by the overhead crane, and is moved onto the electrolytic cell having the electrolytic cell in order to suspend the next electrode plate 4.

When the suspension apparatus A for transporting electrode plates is raised and lowered, four guide rollers 6 provided on the side of the frame 1 of the suspension apparatus engage with the inner surface corners 25 of the guide frame 20, respectively. Then, the electrode plate transporting suspension device A is smoothly and reliably moved up and down without swinging. Also, at this time, even if the electrode plate transporting suspension device A before engaging with the inner surface corner portion 25 of the guide frame 20 slightly swings back and forth and left and right, the guide roller 6 is moved by the expanding portion 26 of the guide frame 20. And the inner surface corner 25 is reliably reached. In the above-mentioned operation, various sensors are provided to detect completion of lifting of the electrode plate, detection of abnormal lifting of the electrode plate, detection of landing on the frame, detection of fullness of the electrode plate, detection of the start of loading of the electrode plate, and the like. Since these devices are known, they will not be described in detail.

The guide plate 20 and the guide rollers 6 guide the smooth operation of the lifting and lowering apparatus A for transporting the electrode plate as described above. It can stop at a predetermined position.

In the embodiment, the guide roller 6 is used as a guide member. However, the guide roller 6 is a preferred example of a guide member, and is not necessarily a guide roller. May be something. Also, four guide rollers 6 are provided at the four corners of the frame 1,
Although four guide frames 20 are provided, it is sufficient that at least two guide frames 20 are provided in each of the diagonal directions. In addition, although the electrode plate transport chain conveyor 2 is shown as an example of the electrode plate storage place, this is not necessarily the electrode plate transport chain conveyor 2 but may be an electrolytic cell.
In the case where the electrolytic cell is used as an electrode plate storage area, when the electrode plate transporting suspension device A is stopped at a predetermined position of the electrolytic cell and the electrode plate 2 is replaced, a conventional overhead crane operator by a slinger is used. There is no need to manually signal the positioning of the electrode plate transporting suspending device A to the electrode plate and finely adjust the position of the electrode plate when the electrode plate is carried in and out. In the embodiment, the electrode plate frame 1 is shown for the cathode plate, but this is also an example,
It may be used for the anode plate or may be used for both electrodes as in the prior art.

[0014]

According to the first and second aspects of the present invention, the positions of the suspension device and the electrode plate are manually required when loading and unloading the electrode plate by a slinger, which is conventionally required. This eliminates the need for fine-tuning work, and makes it possible to automate the work of replacing electrode plates. Also, accidents such as dropping of the electrode plate can be prevented, safety is enhanced, and reliability of the electrode plate transporting suspension device is dramatically improved. According to the third aspect of the present invention, in addition to the above effects, the guide member is engaged with the inner surface corner of the guide frame, so that the engagement is ensured.
