Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a hook block used for cargo handling equipment and the like, and more particularly to a hook block provided with a rope detachment stopper.

[0002]

[Prior Art]

 FIG. 3 shows a hook block that is generally used in conventional cargo handling and transporting equipment, and includes a hook body 1 that is curved and formed in a substantially U shape, and an opening (U shape) of the hook body 1. The rope disengagement metal fitting 2 is provided so as to substantially cross the opening).

The rope detachment prevention metal fitting 2 is formed by using a metal fitting body 21 and a torsion spring 22 as main components, and one end side of the metal fitting body 21 is provided with a pin 23 at a root portion 11 of the hook body 1. It is supported by a support fitting 24 provided at the portion of the above, and a torsion spring 22 is attached to the pin 23. Therefore, the elastic force of the torsion spring 22 causes the other end of the metal fitting body 21 to constantly engage with the inner wall (the inner portion of the U-shape) near the end of the free end side 12 of the hook body 1. Has been done.

The operation of hooking the rope 3 on the above-described conventional hook block will be described. The rope 3 is pressed against the outer surface 21 a of the metal fitting body 21 of the rope slip-off preventing metal fitting 2 while resisting the elastic force of the torsion spring 22. The rope 3 can be positioned inside the hook main body 1 by pushing and moving the metal fitting main body 21 (state of virtual line).

On the other hand, even if the rope 3 is loosened and is engaged with the inner side surface 21 b of the metal fitting body 21, the end portion of the metal fitting body 21 is engaged with the inner wall on the free end side 12 of the hook body 1, so that the rope 3 3 never comes off the hook block.

To remove the rope 3 from the hook block, first, the metal fitting body 2 is manually pushed and moved to be opened (state of virtual line), and the rope 3 is removed in that state.

[0007]

[Problems to be solved by the device]

 In the conventional hook block equipped with the rope detachment prevention metal fitting 2, the rope 3 can be easily hooked, and the rope 3 once hooked never comes off naturally, which is useful for safety measures. It is a thing.

However, the removal work in the work of changing the rope 3 is very complicated because the rope disengagement metal fitting 2 is present. It had to be done and it was dangerous and the workability was very poor.

It is an object of the present invention to provide a hook block provided with a rope slip-off prevention metal fitting that enables easy rope removal work.

[0010]

[Means for Solving the Problems]

 It is a hook block provided with a rope slip-off prevention metal fitting, and one end side of the metal fitting body forming the rope slip-off prevention metal fitting is engaged and disengaged to form a hook body by forming a recess with a projection at the free end side end of the hook main body. A hook block is formed by engaging one end side of the metal fitting body with the protrusion and extending so as to reach the recessed portion.

It should be noted that the protrusion and the recess at the free end side tip portion of the hook body form a recess or a shape equivalent to the recess by providing the protrusion, and form the protrusion by providing the recess. Can be formed by any means of providing both projections and recesses.

[0012]

[Operation] The free end of the hook main body is provided with a projection and a recess, and moreover, one end side of the metal fitting main body of the rope slip-off prevention metal fitting engages with the projection and extends to the recessed portion. When removing the rope, the metal fitting body can be pushed by the rope by positioning the rope in the recess, and the rope can be easily removed from the hook block.

[0013]

【Example】

 The present invention will be described in detail with reference to the embodiments shown in FIGS. It is to be noted that the components designated by the same reference numerals as those in FIG.

First, FIG. 1 shows a hook block according to the first embodiment, in which a projection 13 is formed by forming a recess 14 in the free end side tip portion 12 of the hook body 1. Is configured.

Therefore, the rope 3 is positioned in the concave portion 14 (position of the rope 3a), the rope 3 is pressed against the outer surface 21a of the metal fitting body 21 of the rope detachment prevention metal fitting 2, and resisted against the torsion spring 22 in the figure. The rope 3 can be easily removed from the hook main body 1 by pushing it rightward.

The hook block of the first embodiment has an advantage that it can be easily implemented by providing the recess 14 in the conventional hook block.

Next, FIG. 2 shows a hook block according to the second embodiment, in which a projection 13 is formed at the free end side tip portion 12 of the hook body 1 and the tip end side (lower side in the figure). The hook body 1 is formed by integrally forming the recess 14 with the inner curved surface of the hook body 1.

Therefore, the rope 3 is located at the lower position of the protrusion 13 (position of the rope 3 a), and the rope 3 is pressed against the outer surface 21 a of the metal fitting body 21 of the rope detachment prevention metal fitting 2 so as to resist the torsion spring 22. Then, the rope 3 can be easily removed from the hook main body 1 by pushing and moving it to the right in the figure.

[0019]

[Effect of the device]

 The hook block of the present invention is provided with a projection 13 and a concave portion 14 at the free end side tip portion 12 of the hook main body 1, and moreover, one end side of the metal fitting body 21 of the rope detachment prevention metal fitting 2 is engaged with the protrusion 13. Moreover, since the rope 3 is configured to extend to the concave portion 14, when the rope 3 is to be removed, the rope 3 is positioned in the concave portion 14 to push the metal fitting body 21 of the rope detachment prevention metal fitting 2 by the rope 3 itself. It can be moved and the rope 3 can be easily removed from the hook block.

Therefore, according to the hook block of the present invention, not only can the rope 3 be prevented from coming off during normal use, but also the rope 3 can be easily and safely removed when the rope 3 is replaced. The effect that can be achieved can be achieved.
