Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a lifting device for lifting pallets.

[Prior art]

Conventionally, as shown in Figs. 1 and 2, a plurality of pipes 1 are tied together with a band 2, stacked in a trunk 3, and transported to a factory. ,
This wire 4 is hung on a hook 5 of a crane via a hoist 5a, etc., and the pipe 1 is carried down to the vicinity of a rack 6 shown in FIG. 4 by the crane. Next, use forklift 7 to move pipe 1.
I scooped it up and lowered it to U/Rack 6, and stored Pipe 1 in Rack 6.

According to such a conventional example, the wire 4 is strongly pressed against the pipe 1 (as a result, the pipe 1 is easily damaged).

In addition, since the pipe 1 is suspended by a wire, a special worker is required to hang the wire on the pipe, which is not only inefficient but also difficult and dangerous to balance the suspension.

Furthermore, if the pipe 1 is hung or stored on a rack, the pipe 1 will bend and bend.

[Purpose of the invention]

An object of the present invention is to achieve safe and efficient load transportation work.

[Summary of the invention]

The present invention provides a hanging beam supported by a heavy lifting device, in which a support rod perpendicular to the hanging beam is attached to freely rotate on its axis,
The pallet hoist device is characterized in that a claw is attached to a portion of the support rod below the hanging beam so as to protrude horizontally, and the pallet is attached to the claw by lowering the hanging beam and rotating the rod. It is used to handle cargo loaded onto pallets, including pallets and throats.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 5 to 19.

As shown in FIGS. 5 and 6, two horizontal main beams 8 are connected by two connecting beams 9 to form a hanging beam frame. Furthermore, the two main beams 8 are also joined by a reinforcing beam 10, and are further joined by a turnbuckle 11, thereby reinforcing the fabric beam frame so that it does not shift. Main beam 8
A guide flipper 12, as shown in FIGS. 5, 6, and 7, is attached to each end of the guide flipper 12, respectively. A total of four hollow guides 13, two guides each, are fixed to one main beam 8 at a portion of the main beam B near the joint beam 9, with the kite direction being in the vertical direction. Furthermore, each main beam 8 has a Cheno 1
The hanging brackets 15 with 4 hooked thereon are fixed in a 4-point arrangement. The cheno 14 is connected to a sling 16 that is hooked onto a crane hook. A hollow rotary bracket 17 having a circular outer shape is mounted on the upper end of each guide 13. As shown in FIG. 8, this rotary bracket 17 has a recess on its lower outer periphery, and this recess engages with a stopper 18, and the shift bar 18 is fixed to the guide 13 with a bolt 13a. Therefore, the rotating bracket 17 does not move in the vertical direction but can rotate. A key 19 facing in the vertical direction is screwed into the hollow of the rotating bracket 17.

The following configuration is further added to the above suspension beam configuration. That is, a common support rod is passed through each hollow portion of each guide 13 and each rotary bracket 17, as shown in FIG. A vertically long key groove 21 is machined in the support rod holder, and by inserting the key 19 into this key groove 21, the support rod holder and the rotating bracket 17 can rotate together. Horizontal pin insertion holes n are drilled in the support rod in four stages arranged vertically, and pin insertion holes are also machined horizontally in the rotating bracket 17.

The removal pin must be thick enough to be inserted into and removed from each hole n, 23, and a handle 5 is attached to the end. This handle 5
and the guide 17 are connected by a chain. The upper end of the support rod protrudes slightly upward from the rotary bracket throat 17, and a ring-shaped handle n is fixed to the protruding portion. On the other hand, a horizontal operation lever is fixed to each rotating bracket 17 by welding or the like.

Only one of the operating lever paths along each main beam 8 is as shown in Fig. 6 (it is slightly longer, and a vertical handle is attached to its tip. The two operating levers along the main beam 8 are connected to each other by an operating rod 3 (l).This connection can be made, for example, as shown in FIG. By attaching the concave operating rod to the shaft 31 via the spherical bearing 32, a horizontally rotatable connection is achieved.

As shown in Fig. 8, a horizontally protruding pawl is fixed to the lower part of each support rod, as shown in Fig. 9, and the tip of the pawl has a shape slightly bent upward. This is to prevent the pallet from coming off easily.

Next, I will explain the composition of the palette.

As shown in FIG. 10, the pallet style is provided with an outer frame of the pallet by assembling side frames and an end frame with wire hooks 36a by welding into a rectangular shape. On that side of the side frame, Figure 10,
As shown in Fig. 11, an elongated hole 37 large enough for a claw saw to rotate through is drilled, and in the side frame located near the elongated hole 37, there is a gap between the reinforcing materials as shown in Figs. 11 and 12. It is fixed and has sufficient strength to withstand lifting. Five receiving materials 39 are fixed to the side frame in parallel with the end frame. The fixed height of the receiving material 39 is set so that when the pipe I is placed on the receiving material 39, the pipe 1 does not protrude upward from the side frame. As shown in FIGS. 13 and 14, fixing stoppers 41 are fixed to several ends of the cargo receiving material 39 by projecting upwards from the receiving material 39 with bolt buttons, and furthermore, the material receiving material 39 and the end frame are fixed. The sliding material 42 is also fixed to that lower part. The sliding member 42 has an arc-shaped recess on the lower surface, and is capable of sliding stably on a guide rail 43 fixed to the rank. A movable stopper device is installed on the two load receiving blades. This movable stopper device includes a stopper plate portion that sandwiches the receiving material 39 from above and below, a bracket 46, and a stopper plate 4.
5 and bolt 47 assembled into the bracket. The bolt 47 is turned into a nut to remove the stopper plate 4.
5 and the bra repellent 46 (the stopper plate part will be fixed to the cargo receiving material 39 by sandwiching it, and if you reverse the nanding and loosen it, the stopper plate 45 etc. will be along the cargo receiving material 39). Can be moved.

In this embodiment, when the pipe 1 is transported into the factory, it is loaded onto a pallet so that the pipe 1 is received on the receiving material 39. Next, as shown in Fig. 16, stack the pipes l in the trunk 3 on the pallet jaws 2 and 1.
As shown in Figure 7, leave a space between the piles of Comrade Noharesoto 34 in which the support rod can be raised and lowered (.In this way, pipe 1 is carried to the factory using the trunk.Do not put sleepers between the upper and lower pallets U. Even if pallets are piled up,
Since the pipe 1 does not protrude upward from that side frame of the pallet, the pipe 1 will not be damaged by the heavy pressure of the upper pallet.

Therefore, mass transportation can be carried out more efficiently than by stacking via railroad ties.

When the truck 3 arrives at the factory, the hanging rod 16 is hooked onto the hook of the overhead crane, and by raising this hook, the entire hanging beam is lifted and lowered onto the pallet on the truck 3. When the hanging beam is lowered onto the pallet, the guide flipper 12 first catches the corner of the pallet and moves the hanging beam horizontally so that the horizontal position of the claw matches the horizontal position of the elongated hole 37. Guide the whole thing. After this guiding action, the main beam 8 lands on the side frame A. Next, rotate the operation lever row with the handle, and the operation lever will be activated.
The operating levers Z connected by the rotating bracket 17. rotate simultaneously. The support rod also rotates. Therefore, the claws, which were parallel to each other, rotate and are pushed into the elongated hole 37. Thereafter, when the entire suspension beam is lifted by an overhead crane, a plurality of pallets are lifted at once and transported efficiently and in large quantities to the destination point, as shown in FIGS. 18 and 19. According to this kind of lifting, the pipe 1 is attached to the receiving material 39
Since the pipe is supported at multiple points, the pipe l will not bend or become bent. Also, the horizontal span of the claw 3 is wide and the rebalance is also good. Furthermore, when the pallet is transported by truck 3 or crane, moving the movable stopper device so that the pipe 1 is sandwiched between the stopper plate of the movable stopper device 44 and the fixed stopper 41 prevents the pipe 1 from rolling during transportation. There is no displacement movement (, pipe 1
This will prevent the suspension from becoming unbalanced if it gets damaged. If you want to adjust the number of pallets that should be raised faster each time, pull the handle 5 to remove the pins, then pull the handle n upwards to raise or lower the support rod. , the length of the downward protrusion of the support rod is determined so that the claw faces the long holes 37 when the main beam reaches the top of the pallet.

After that, the pin example is passed through the rotating bracket 17 and inserted into the other hole ρ, and the vertical movement of the support rod is fixed again. If you do as in 2, the elongated holes 37 of the claws can be used to handle either a single pallet or multiple pallets.
Easy positioning and efficient work.

〔Effect of the invention〕

As described above, according to the present invention, the load is handled by hooking the whole pallet up with the claws, which eliminates the dangerous and tedious work of hanging wires under the load in a well-balanced manner and the work of tying pipes. Therefore, the effect of carrying out safe and efficient transportation work can be obtained.
