Description

[Detailed Description of the Invention] [Object of the Invention] The present invention relates to a masonry work device for building retaining walls such as retaining walls by stacking stones, especially concrete blocks for masonry. be.

In general, there is a method of constructing earth retaining walls using concrete forms, but since the cost is several times that of masonry, many masonry workers use stone, especially concrete blocks for masonry.

However, in conventional masonry work, a party of 5 to 6 people manually unloads concrete blocks transported by trucks, moves them to the masonry position, and lays the stones. Met.

Therefore, it takes a lot of effort to move and transport the concrete blocks, and the workers are forced to do hard labor all the time, not only because the footing is poor, but because they have to handle heavy objects, they have to work hard to move and transport the concrete blocks. There were problems in that accidents such as pinching of objects were likely to occur, which was dangerous.

Furthermore, in recent years the masonry workforce has been aging, making it difficult to secure skilled workers for the future.

The present invention was made in order to solve the problems of conventional masonry work as described in -1. The purpose of the present invention is to mechanize and automate masonry work, thereby reducing the burden of heavy labor and dangerous work on workers. We have developed a new masonry work device that frees you from masonry work, saves labor in masonry work, reduces manpower and costs, and has an extremely simple structure that can be easily handled without requiring a lot of force. It is on offer.

[Structure 1 of the invention - M Shin - 1 solution] Lbe Jζ matter p - Publishing Shioichi The masonry work device of the present invention has a weightless operation amount such as a balancer device on the arm of a base machine such as an excavator. A lifting device is attached, and a gripping device is suspended from the tip of the weightless operation amount lifting device via a suspension wire, and the gripping device is connected to two gripping rods and an intermediate portion between these gripping claws. holding rods that rotatably hold the parts at predetermined intervals, and two actuators that are pivotally attached to the -1 ends of the clamping rods and are mutually rotatably connected in a downward dogleg shape. It is characterized by being constructed on a rod and having a suspension wire connected to the central connecting portion of the operating rod.

EMBODIMENT OF THE INVENTION Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a shovel-type excavator main body as a base machine, and an upper rotating body 11 rotates with respect to a lower traveling body 1a. A boom 2 is attached to the excavator body 1 so as to be able to rotate downward, and an arm 3 is attached to the tip of the boom 2.
is similarly pivoted so that it can rotate downward. Furthermore, a packet 4 is pivotally attached to the tip of the arm 3, so that it can swing vertically.

A balancer 5 as a zero-gravity operating device is attached to the arm 3. The balancer 5 can freely lower the suspension wire 6 by the action of a spring attached to the groove Jf1 (not shown). The strength can be adjusted.

Note that the balancer includes, in addition to those using springs described in 1., electric motors, hydraulic or pneumatic cylinders, and balancers based on the principle of leverage.

A clamping device 7 using a so-called trouble joint mechanism is attached to the lower end of the suspension wire 6. The clamping device 7 includes two clamping rods 8, 8 which sandwich the front and rear of the concrete block B, and a retaining rod 9 which pivots the substantially opening portions of these clamping rods 8, 8 to hold them at a predetermined interval. , two operating rods 10.1 which are pivotally connected to the upper ends of the clamping rods 8, 8, respectively, and are rotatably connected in a downward dogleg shape.
The suspension wire 6 is connected to the intermediate connecting portion 10a of the operating rod 10.

Since the masonry work device of this embodiment is configured as described above, first, the excavator 1, boom 2, or arm 3 is moved appropriately so that the clamping device 7 places the concrete block B on top of the concrete block B to be moved. to be located. Next, the clamping device 7 is pulled down by hand, and as shown in FIG.
1- Set the clamping rods 8 so as to sandwich the front and rear of the concrete 1 block B. In this state, while holding the suspension wire 6 slightly, the intermediate connecting portion 10a of the two operating rods io, io moves upward, and at the same time the operating rods 10, 1
Both ends of the 0 move outward with a strong force and spread out the upper ends of both clamping rods 8°8.

The middle portions of the clamping rods 8, 8 are pivotally connected to both ends of the holding rod 9, and are held so as to maintain a predetermined distance, so that the clamping rods 8,8
When the upper end is pushed apart with a strong force, the lower parts are drawn inward and the concrete block B
grip firmly.

If the inner protrusion 8a is provided at the lower end of the clamping rod 8, even if the gripping force of the gripping device 11 becomes loose, there is no fear that the concrete block B will hit this and fall off, and can be safely gripped.

[Effect of the invention 1 (1) The device of the present invention can shorten the on-site operation of masonry blocks, improving work efficiency and shortening the work period. It can be used for other work, and the construction cost can be significantly lowered.

(2) The device of the present invention can relieve laborers from hard labor and improve work safety.

(3) Since it has an extremely simple structure, it can not only be provided at low cost, but also easy to handle and can be easily lifted with little force.
