Description

[Detailed description of the invention] The present invention relates to an attachment type crane device.

For example, in landscaping and housing construction work, in addition to earthwork work such as excavation, crane work to suspend objects is also required.
There is a demand for a work machine that can perform both earthwork work and crane work with a single machine.

``In view of the above points, the present invention is an attachment that can perform both earthwork work and crane work, improving versatility, and also simplifying the configuration through a rational drive configuration. The purpose of the present invention is to provide a ceremonial relay device.

Next, embodiments of the present invention will be described in detail based on illustrative drawings.

A transporting device 2 is provided at the front of a traveling machine base equipped with a crawler type traveling device 1, and an excavating device 3 is provided at the rear, and a driver's seat 4 is placed between both devices 2 and 3 so that it can be operated even when facing either the front or the rear of the aircraft. A first control section 5 for operating the traveling device 1 and the transport device 2 is provided in front of the driver's seat 4, and a second control section 6 for operating the excavation device 3 is provided at the rear. The traveling device 1 and both devices 2 and 3 are configured to be driven by hydraulic pressure, which is an example of a fluid pressure type, so that the traveling device 1 and both devices 2 and 3 can be used for both scooping and transporting earth and sand, etc., and ground excavation while using one device. The earthmoving machine is configured so that it can be carried out.

A frame 7 is connected to the rear of the fuselage, and a bracket 8 is attached to the frame 7 so as to be repositionable and fixed in the lateral direction of the fuselage along a guide 9, and a base 10 is pivoted to the bracket 8 along a vertical axis. The excavating device 3 is connected to the base 10, and the excavating device 3 can be moved in the lateral direction of the machine during lifting work to expand the work range.
On the other hand, when not in operation, the excavator 3 is configured so that it can be placed in a horizontal position and compactly stored within the width of the machine body.

The excavation device 3 swings the packet 12 onto a working arm 11 which is formed by a first arm 11a which is swingably and pivotally connected to the base 10 and a second arm 11b which is swingably and pivotally connected to the base 10. The base 10 and the first arm 11a1 are freely pivotally connected.
Hydraulic cylinders = 13 are interposed between the first arm 11a and the second arm 11b1, and between the second arm 11b and the packet 12, and run.

The construction is such that hydraulic pressure is supplied from the machine stand to the hydraulic cylinders 13 through hydraulic supply pipes 14, so that the working arm 11 is driven vertically and flexed and extended, and the packet 12 is It is configured to be driven and moved to perform ground excavation work.

. The excavation equipment 3 can be configured to be capable of crane work by attaching a crane device 15 in place of some of its constituent members, and the specific configuration of the attachment type crane device will be described in detail below.

That is, the crane device 15 has the first arm shaft 11a.
There are two attachment tools 16c, 16c in the longitudinal direction of the
A second boom 16b is slidably fitted onto a first boom 16a having a slider so as to be slidable and extendable to each other to form a telescoping boom 16, and the tip of the second boom 16b of this telescoping boom 16 is A drum 18 with a wire 17 wound thereon is rotatably provided, a hydraulic motor 19 is interlocked with the drum 18, and seven hanging hooks 20 are connected to the wire 17 so as to be movable up and down.

In order to install the crane device 15, the 17th J-m 1
1a, the second arm 11b1, the hydraulic cylinder 13 which drives and moves the packet 12, the coupling 21 in the middle of the hydraulic pressure supply pipe 14, and the hydraulic cylinder 1 interposed between the two.
3 and the second arm 11b, the first boom 16a is connected and fixed to the first J-arm 11a, and the rod 13a of the disconnected hydraulic cylinder 13 is connected to the second boom 16b by drilling it into the first boom 16a. At the same time, the hydraulic supply pipe 14 is connected to the piping system 19a extending from the hydraulic motor 19 through the coupling 21, thereby controlling the swinging of the first arm 11a. In addition to the rotation, the second boom 11b is driven to extend and contract in the same manner as the second arm 16b is driven and swung, and the hydraulic motor 19 is driven in the same manner as in the case of supplying pressure oil to the packet 12 to move the hook 20. It is constructed so that it can be lifted and lowered to carry out crane work for suspending and transporting articles.

In summary, the attachment type crane device according to the present invention has a first arm 11 to which a hydraulic cylinder 13 is attached.
A, the first arm 11a is pivoted to be vertically swung by the hydraulic cylinder 13 at the tip thereof, and another hydraulic cylinder 13 is attached to the tip of the first arm 11a. The arm 11 is composed of a second arm 11b configured to rotate the packet 12, and is configured to be vertically swingable by a hydraulic cylinder 13 interposed between the first arm 11a and the machine frame. A crane device 15 is detachably attached in place of the second arm 11b, and the plurality of attachments to the first arm 11a include a first boom 16a equipped with tools 16c and 16c, and a first boom 16a that slides onto the first pool 16a. a second boom 16b, which is fitted with the second boom 16b and whose lower end is attached to the rod tip of the hydraulic cylinder 13; and a hydraulic motor, which is attached to the upper end (tip) of the second boom 16b. a drum 18 for winding the wire 17 which is forcibly rotated by a hydraulic motor 19;
It is characterized in that it consists of a piping system 19a which is extended from side to side and is connected in the middle of a hydraulic pressure supply pipe 14 to a hydraulic cylinder 13.13 for driving and moving the packet 12.

The hydraulic cylinder 13 that operates the second arm 11b of the working machine is capable of performing earthwork work for ground excavation by hydraulically driving the pick, the packet 12, and the working arm 11 to rotate, vertically swing, and bend it. Since the hydraulic oil supply pipe 14 for operating the packet is intended to be used as it is for the hydraulic oil supply pipe to the hydraulic motor 19, the crane device itself is used for the boom extension and retraction operation. Furthermore, the piping system 19a extending from the hydraulic motor 19 can be made to have a minimum length, making it possible to construct the crane device itself extremely economically and to reduce its weight. It has advantages such as being easy to handle when attaching and detaching from the first arm, and being easy to put together as a simple structure.
