Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete block hoisting tool.

[0002]

[Problems to be solved by conventional techniques and devices]

 Concrete blocks such as inverted U-shaped gutters with closed tops are often used, but such gutter blocks are often large, and there was no easy-to-use block hoisting tool to hoist them.

The Applicant has paid attention to the fact that such a concrete block has a rectangular window on the upper surface, and studied whether there is a method of lifting using this window, and the present invention was completed.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

Left and right slidable left and right corner tubes 2 and 3 are housed inside the right and left sides of the horizontal rectangular tube 1, and channel-type hanging pieces 4 and 5 are slidably fitted into the right and left sides of the horizontal rectangular tube 1. Each of the left and right square tubes 2 and 3 is connected by a through pin 6 through a long window 1 ′ · 1 ′ provided on the front surface of the horizontal square tube 1, and the lower ends of the left and right channel-type hanging pieces 4, 5 are connected. Horizontal locking pieces 4'and 5'project toward the outside respectively, and the left corner cylinder 2 and the right corner cylinder 3 are opposed to each other through a long window 1 "provided on the upper surface of the horizontal corner cylinder 1. The lower ends of the doglegged links 7 and 8 projecting upward from the horizontal rectangular tube 1 toward the base are pivotally attached to face each other, and the upper surface of the horizontal rectangular tube 1 is substantially bent at the bent portions of the doglegged links 7 and 8. The upper parts of the hanging protrusions 16 and 17 which are erected in the opposite state are pivotally attached to each other, and the lower ends of the upper suspension link segments 9 and 10 are pivotally attached to the upper portions of the doglegged links 7 and 8, respectively. The up-and-down angle tube 11 is fitted to the guide square tube 13 standing upright in the central portion of the square tube 1, and the horizontal link pieces 12 attached to the up-and-down angle tube 11 are attached to the left and right ends of the upper suspension link pieces 9 and 10. The present invention relates to a block lifting tool, wherein an upper end portion is pivotally attached by a pin 14 and hook receivers 15 are attached to the left and right pins 14.

[0006]

[Action]

 When hooking the wire rope to the left and right hook receivers 15 and hoisting the center of the wire rope upward with the hook of the lifting device, the lower ends of the left and right dogleg-shaped hanging link pieces 7 and 8 are linked. Since the left and right corner tubes 2 and 3 slide outward while the pivoting parts of the hanging projections 16 and 17 pivot respectively outward, they simultaneously project to the lower ends of the left and right channel type hanging pieces 4 and 5. The horizontal locking pieces 4'and 5'provided also slide outward to lock the lower surfaces at the left and right ends of the block a, so that the block a can be reliably lifted and moved.

At this time, the heavier the block a is, the stronger the force is to push the horizontal locking pieces 4 ', 5'to the outside, so that the block a can be safely lifted and moved.

【Example】

 The drawings show an embodiment best suited for the present invention.

Left and right slidable left and right slidable cylinders 2 and 3 are provided inside the left and right slidable horizontal square cylinders 1 formed of rectangular cross-sections, and slidable to the left and right of the horizontal square cylinders 1. Fit the channel-shaped hanging pieces 4.5. Slotted holes 1 '・ 1' are pierced on the vertical plate surface of the right back of the horizontal rectangular tube 1, and the channel-shaped hanging pieces 4, 5 and the left rectangular tube 2 and the right rectangular tube 3 are formed with the long holes 1 '・ 1'. The horizontal locking bodies 4'and 5'protrude outward from the lower ends of the left and right channel-type hanging pieces 4 and 5, respectively.

A long window 1 ″ · 1 ″ is formed in the left and right of the upper surface of the horizontal rectangular tube 1 toward the center, and the lower ends of the doglegged links 7 and 8 are opposed to the left and right long windows 1 ″ · 1 ″. Insert the parts, and insert the long holes 7 ′ and 8 ′ provided at the lower ends of the left and right doglegged links 7 and 8 through the long holes 1 ′ and 1 ′ provided on the right rear surface of the horizontal rectangular tube 1. Pins 26 are pivotally attached to the bases of the left and right square cylinders 3 and face the upper surface of the horizontal square cylinder 1 at the substantially bent portions of the doglegged links 7 and 8 projecting above the horizontal square cylinder 1. The upper part of the two-piece suspension projections 16 and 17 standing upright is pivotally attached by pins 23 and 23.

Reference numeral 24 is a washer for the pin 23, 25 is a split pin, 27 is a washer for the insertion link pin 26, 28 is a split pin, and 19 is a left square cylinder 2 and a right square cylinder 3 inside the horizontal square cylinder 1. A guide roller with a collar that can be slid left and right, 20, 21 are reinforcing rims of the horizontal rectangular tube 1, and 22 is a split pin for the insertion pin 6. .

The lower ends of the left and right upper suspension link pieces 9 and 10 formed of two pieces are pivotally attached to the upper portions of the left and right dogleg links 7 and 8 by link pins 29 and 29.

The elevating and lowering angle tube 11 is vertically movably fitted into a square tube 13 which is erected on the central upper surface of the horizontal rectangular tube 1, and the left and right ends of a horizontal link piece 12 attached to the upper part of the vertical rectangular tube 11 are attached to the left and right sides. Pins 14 are pivotally attached to the upper ends of the hanging link pieces 7 and 8, and the bases of the hook receivers 15 and 15 are pivotally attached to the left and right link pins 14.

When the left and right hook receivers 15 are lifted upward, the lower ends of the doglegged link pieces 7 and 8 slide the left corner tube 2 and the right corner tube 3 toward the outside by the linking action. The channel-type hanging pieces 4 and 5 connected together are also slid to the left and right on the horizontal rectangular tube 1 at the same time, and the horizontal locking pieces 4'and 5'are rectangular windows on the upper surface of the gutter block a. Since the lower surfaces of the lower end edges of the left and right inner holes are locked, the block a can be reliably lifted and moved.

[0015]

[Effect of the device]

 According to the present invention configured as described above, when the hook receiver is lifted upward, the linking action causes the locking pieces protruding from the lower ends of the left and right channel-type hanging pieces to slide outward, and Since the lower surface of the left and right edges is locked, the block will be lifted securely, and the heavier the block is, the stronger the force is to push the locking piece outward, so the block can be safely lifted and moved practically and conveniently. It becomes a device.
