Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The transport device according to the present invention is located at the tip of a lifting line from a carrier hung by a roller hung on a skyline installed at a site where timber is collected by a logging machine. When lowering the hooks provided to lift timber, the carrier body is equipped with a battery, and the motor provided in the carrier body can be operated remotely from the ground. In a carrier device for transmitting to a stun, an electromagnetic clutch is provided on a rotating shaft of the motor so that the rotational force of the motor is transmitted to a capstan via a speed reduction mechanism (hereinafter, this is referred to as a carrier). That said)).

2. Description of the Related Art Conventional carriers include those in which a winding wire is built in a drum provided in the carrier and those in which a winding wire is not built in. The one in which the winding wire is built in the drum provided inside the carrier is one in which an endless lifting line is drawn by a collecting machine to rotate the drum, and the hook provided at the tip of the winding wire is raised and lowered. Is. A carrier that does not have a built-in winding line does not have the above drum, and since there is no winding line there, a rope with one end tied to the hook of the carrier on the skyline is hung and the rope is towed. The work was done manually. The work of pulling the rope and lowering the hook from the carrier relied on human power, so a person needed to pull the hook and lower it to the place where the timber was located. Needed extra effort.

Prior to this, the inventor of the present invention installed a small engine in the main body as a power for lowering the lifting line of a carrier which does not have a winding wire in order to reduce such labor and improve work efficiency. A centrifugal clutch is installed to transmit the rotational power of the power, and the power is further transmitted to the capstan via the reduction gear, and by remotely operating this, the capstan with the lifting line is rotated to forcibly lower the hook. There is a patent application for which a patent applicant has applied for a patent of 1995 Japanese Patent Application No. 267933 with the title of the invention as "carrier" by developing a technology that facilitates the work. However, according to the invention, since the rotation speed of the small engine is remotely controlled and the power is transmitted through the centrifugal clutch, the rotation speed of the engine that is constantly rotating is increased or decreased as necessary to reduce the engine speed. Since the centrifugal clutch is connected or disengaged depending on the difference in the number of revolutions, there was a problem that the engine mounted on the carrier rising above the skyline could not be stopped midway. In addition, the conventional one with a built-in winding line has a straw line that rotates the capstan of the carrier and pulls it with a lumber collector to forcibly lower the hook, but a small engine in the carrier body. Alternatively, if a motor is provided so that the capstan can be rotated, the conventional straw line is not required, and the lifting line hook can be forcibly lowered.

[0004]

SUMMARY OF THE INVENTION The present invention relates to a carrier which does not have a winding wire built therein, in order to lower the hook at the tip of the lifting line from the carrier on the skyline to a place where there is timber. It is equipped with a motor to drive the power storage area that serves as a power source and the capstan of the carrier, and an electromagnetic clutch is connected using this, and the capstan is powered while reducing the rotation speed via a speed reducer. The capstan on which the lifting line is wound is rotated and the hook is lowered. By remote-controlling the process of stopping the operation, the work of pulling a rope from the ground, which was conventionally done manually, is no longer necessary, and it becomes possible to easily stop the operation of the motor by remote control. You can easily drop a hook on the ground. In this way, the process of manually pulling the rope is eliminated, and the labor of the work is reduced by remote control so that the labor can be saved.

[0005]

In order to solve the above-mentioned problems, a carrier device according to the present invention mounts a power storage area on a carrier body, uses this as a power source, and installs a motor on the carrier body. By connecting with a clutch, the rotational force of the motor is further transmitted to the capstan via the speed reducer, and the lifting line wound on the capstan can be forcibly lowered.

[0006] In the field where timber is collected by a lumber collector, when the lumber is hoisted by lowering a hook provided at the tip of the lifting line from a carrier that is hung on a roller hung on the erected skyline. The carrier body is provided with a battery, and the motor provided in the carrier body is remotely controlled from the ground so that the rotational force of the motor is transmitted to the capstan while being decelerated through the speed reducer. This transport device is characterized in that an electromagnetic clutch is provided on the rotating shaft of the motor to connect the power of the motor to the speed reducer, and the rotational force of the motor is reduced to be transmitted to the capstan.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The carrying device is provided with an electromagnetic clutch on a rotary shaft of a motor provided in a carrier body, and a reducer is provided on a rotary shaft of the electromagnetic clutch to reduce a rotational force of the motor to reduce a capstan. The power is transmitted so as to rotate. The shaft of the speed reducer is connected to the rotary shaft of the electromagnetic clutch. With the electromagnetic clutch, the rotation of the motor can be connected and transmitted.

A speed reducer shaft is provided on the shaft of the electromagnetic clutch, a pulley provided on the shaft and a pulley provided on the next speed reducer shaft are connected by a V belt, and a gear is provided on the shaft provided with the pulley. The chain is connected to a gear provided on the shaft of the capstan to reduce the rotational force and transmit it to the capstan.

This transporting device is a mechanism that acts as a speed reducer with a combination of a pulley and a gear via an electromagnetic clutch. However, it is not a reduction mechanism such as a combination in which large and small pulleys are connected by a V-belt or a combination in which large and small gears are connected by a chain, but a reduction gear product in which gears are combined is used as a reduction mechanism for a conveying device according to the present invention. By connecting the rotational force of the motor to the reducer shaft via the electromagnetic clutch, the output side of the reducer may be directly connected to the capstan shaft, or the output side shaft may be indirectly connected. Alternatively, the gear may be connected to the shaft of the gear, and the gear may be connected from the gear to a gear provided on the shaft of the capstan. In these cases, the reduction gear as a product is used.

It is easy to stop the operation from the ground by remotely controlling the motor provided in the carrier body. The rotational force of the motor is connected by the electromagnetic clutch and the power is transmitted to the capstan via the reduction gear. Then, the lifting line wound on the capstan was wound up, and the hook for hanging the wood provided at the tip of the lifting line was forcibly lowered.
