JPH07206367A - Remote unhooking device for hook rope for crane - Google Patents

Abstract

PURPOSE:To provide a remote unhooking device which unmanually unhooks a hook rope at the tip of the wire of a crane or the like. CONSTITUTION:A hook 3 rotated around an axle 2 is attached to the lower part of a hook body 1 and after a rope 8 is hooked, the hook 3 is erected and locked by a stopper 5. In release of the rope 8, an electromagnet 6 is energized by a battery box 7 by operation of a sensor through remote control. The stopper 5 is attracted, the stopper 5 is unlocked from the lock part 9 of the attraction hook 3, the hook 3 is released, and the rope 8 is unhooked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook attached to the tip of a wire such as a crane.

[0002]

2. Description of the Related Art Conventional hooks have only been used to hang ropes or the like that bind luggage.

[0003]

The conventional hooks are:
When removing the rope from the hook, it was necessary to manually remove the rope, but this was a dangerous task in high-altitude work.

[0004]

[Means for Solving the Problem] In order to solve the problem, the rope of the hook is detached by a remote control without manual labor.

[0005]

[Operation] Attach the hook that rotates around the shaft to the bottom of the hook body, hang the rope on the hook, raise the tip of the hook, and stop with the stopper attached to the body. The stopper is connected to the electromagnet, and the battery is attached to the main body and the sensor and the remote control energize the electromagnet from the battery to attract the stopper, the hook system stop is released, and the rope is opened.

[0006]

Embodiments of the present invention will be described with reference to the drawings. Fig. 1, Attach the hook (3) around the bottom of the hook body (1) at the tip of the wire of the crane etc. so that it can rotate around the shaft (2). Attached to the hook body (1) is a stopper (5) supported by a pin (4), an electromagnet (6) for attracting the stopper (5), and a battery box (7) having a remote control receiver.

When the rope (8) is hung on the hook (3) to raise the hook (3) and the stopper (5) is pushed by the system stopper (9), the stopper (5) becomes like a dotted line, and the system stopper (5) When 9) enters the inside of the stopper (5), the stopper (5) lowers and the system stopper (9) stops at the stopper (5). Since the stopper (5) is stopped by the stopper receiver (10), it cannot be rotated any more and the hook (3) cannot be opened.

The wheel (11) is hung by the wire of the crane, and when the rope (8) of the hook (3) is unloaded, it is transmitted to the remote control receiving section of the battery box (7) by the remote control, and the battery is operated by the sensor. To energize the electromagnet (6) to attract the stopper (5), the system stop (9) of the hook (3) is opened downward as shown by the dotted line, and the rope (8) is opened.

Although the hook (12) is a conventional hook,
In the case of a mocquer, if one side is hooked on the hook (12) and the other side is hooked on the hook (3), the hook (3) can be opened by the remote controller at the time of grounding, and the wire can be wound up to release the mocquee load. Assembling the beam, etc., by suspending it at two points, hook one side of the rope to the hook (12) and the other side to the hook (3), and when the beam etc. is fixed, switch on the remote control and open the hook (3). It is possible to remove the rope that has been hung, etc. without the need for manual labor.

FIG. 2, the electromagnet (6), the battery box (7) and the remote control receiver are omitted, and the rope (13) is pulled to pull the stopper (5) and remove the system stop (9) of the hook (3). It is the hook according to claim 2.

[00011]

EFFECTS OF THE INVENTION In the conventional hook, the rope cannot be removed without manual work, but it is dangerous to remove the rope in high places. There is no need to walk over the local beams.

Claims (2)

[Claims] 1. A hook body at the tip of a wire of a crane or the like, a stopper for stopping a hook that rotates around an axis and a system stop portion at the tip of the hook, an electromagnet for attracting the stopper and a power source for the electromagnet, and a remote controller for energizing the electromagnet. By attaching the remote control receiver and sensor of the remote control switch, and turning on the switch of the remote control transmitter, the electromagnet is energized from the power supply of the hook body to suck the stopper, and the system stop at the hook tip that was stopped by the stopper is the stopper. This is a device for removing the rope from the hook of a crane, which is characterized in that the hook comes off and the rope hanging on the hook is released. 2. The hook body at the tip of the wire of a crane, etc. is equipped with a stopper that stops the hook that rotates around the shaft and the system stop portion of the hook tip, and the system stop portion of the hook tip comes off from the stopper by pulling the stopper with a rope or the like. The remote hook rope removing device for a crane according to claim 1, wherein the hook is rotated and the rope hanging on the hook is released.
