Anti-drop lifting hook with stop rod

Technical Field

The utility model relates to a lifting hook especially relates to an anticreep lifting hook with locking lever, and it belongs to the lifting hook field.

Background

A hook is one of the most common spreaders in hoisting machinery. The hook is often suspended from the wire rope of the hoisting mechanism by means of a pulley block or the like. For safety reasons it is sometimes necessary to close the hook to prevent the hoisted object from unhooking. As shown in the attached drawing 5, a buckle is added at the opening of the lifting hook of the existing anti-dropping device, and the buckle is propped against the tail end of the lifting hook. Such a clasp is not easily operated with one hand due to the action of the spring.

Further, the tail end of the guide groove is connected with a magnet, the stop rod is rotatably connected with a guide sleeve, and the guide sleeve is made of iron materials.

Further, the counterweight rod comprises a fixed rod, a first guide rod and a second guide rod; a first guide sleeve and a second guide sleeve are arranged at two ends of the fixed rod in parallel, the first guide rod is connected in the first guide sleeve in a sliding manner and can be relatively fixed with the first guide sleeve, and the second guide rod is connected in the second guide sleeve in a sliding manner and can be relatively fixed with the second guide sleeve; the stop rod and the balancing weight are respectively connected to two ends of the first guide rod and the second guide rod.

Furthermore, the first guide sleeve and the second guide sleeve are connected with a set screw, the first guide rod can be relatively fixed with the first guide sleeve through the set screw, and the second guide rod can be relatively fixed with the second guide sleeve through the set screw.

Further, the balancing weight is respectively fixedly connected with the first guide rod and the second guide rod through threads, so that the relative positions of the balancing weight on the first guide rod and the second guide rod can be adjusted.

Has the advantages that: the utility model discloses an anticreep lifting hook with locking lever, because of the effect of balancing weight, under the effect that does not have the external force, the locking lever is arranged in the guide way all the time and thus seals the couple body, has effectively prevented to hang the thing unhook; the magnet in the guide groove can prevent the counterweight block from rotating randomly; the balancing weight is connected with the first guide rod and the second guide rod through threads, so that the rotation force generated by the balancing weight can be conveniently adjusted, and the whole structure is simple and flexible.

Detailed Description

The principles and features of the present invention will be described with reference to the accompanying fig. 1 to 5, wherein the examples are provided only for explaining the present invention and are not intended to limit the scope of the present invention.

An anti-drop lifting hook with a stop rod comprises a hook body 1, a balance weight rod 5, a balance weight block 4 and a stop rod 7.

The hook body 1 comprises an integrally formed connecting part 2 and an arc-shaped hook part 3. The connecting part 2 is provided with threads, and the hook body 1 can be fixed on a corresponding using device through the threads. The weight lever 5 includes a fixing lever 10, a first guide lever 11, and a second guide lever 12. The fixing rod 10 is U-shaped, and a first guide sleeve 14 and a second guide sleeve 15 are respectively arranged at two ends of the fixing rod 10. The fixing rod 10 penetrates through the hook part 3, and the first guide sleeve 14 and the second guide sleeve 15 are respectively arranged on two sides of the hook body 1. The first guide rod 11 is slidably connected to the first guide sleeve 14, and the second guide rod 12 is slidably connected to the second guide sleeve 15. The first guide sleeve 14 and the second guide sleeve 15 are respectively connected with a set screw 13, the first guide rod 11 is relatively fixed with the first guide sleeve 14 through the set screw 13, and the second guide rod 12 is relatively fixed with the second guide sleeve 15 through the set screw 13. The top ends of the first guide rod 11 and the second guide rod 12 are respectively connected with a balancing weight 4, and the bottom ends of the first guide rod 11 and the second guide rod 12 are respectively connected with two ends of the stop rod 7. The outer portion of the stopping rod 7 is rotatably connected with a guide sleeve 9, and the guide sleeve 9 is made of iron materials. The bent hook part 3 is provided with a guide groove 6, and the tail end of the guide groove 6 is provided with a magnet 8. If no external force is applied, the counterweight rod 5 can rotate under the action of the counterweight block 4 until the stop rod 7 enters the guide groove 6 and is mutually attracted with the magnet 8, so that the hook part 3 is closed to play a role of preventing falling.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
