Description

Crane unhooking-proof and false hooking-proof steel wire rope device

Technical Field

The utility model belongs to the technical field of the hoisting machinery technique and specifically relates to an mousing-hook and prevent mistake hook wire rope device for double hook hoist.

Background

The unhooking prevention device of the crane is a safety protection device used for preventing a lifting appliance or a steel wire rope from being unhooked due to too much descending of a lifting hook caused by misoperation or crane faults when the crane is lifted. The unhooking prevention device of the existing crane comprises a closing plate hinged with a positioning bolt penetrating through a hook handle, the free end of the closing plate is located on the inner side of the tip of a hook and closes a hook opening, and a spring connecting rod is arranged between the upper portion of the closing plate and the hook. When the device is used, the closing plate is pushed to rotate around the positioning bolt to compress the spring connecting rod to open the hook opening, and the steel wire rope is buckled into the hook; then the spring connecting rod is reset to tightly push the closing plate to close the hook opening, so that the steel wire rope is prevented from unhooking. Because the closing plate rotates repeatedly and opens and close the lifting hook mouth, and when receiving the collision at the handling in-process, the spring coupling rod is damaged by the deformation easily, causes elasticity to reduce or became invalid, makes it not reach anticreep safety protection's effect, and anti collision ability is low, and life is short. Aiming at a double-hook crane with main and auxiliary hooks, when the main hook is used for lifting and stabilizing a cargo, the phenomenon that the auxiliary hook is easy to swing and mistakenly hooks a steel wire rope of the main hook exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that a collision resistance ability is high, long service life is provided to can prevent that vice lifting hook from catching hold of with a hook wire rope's hoist mousing-hook and prevent mistake hook wire rope device when using the steady hook of main hook handling goods.

In order to solve the above problem, the utility model discloses a technical scheme is: the steel wire rope device for preventing unhooking and mistaken hooking of the crane comprises a closing plate hinged with a positioning bolt penetrating through a hook handle, wherein the free end of the closing plate is positioned on the inner side of the tip part of a hook and closes a hook opening, and the upper part of the closing plate is provided with a balancing weight through a connecting rod; an arc-shaped baffle is hinged to the positioning bolt, and the free end of the arc-shaped baffle is located on the outer side of the tip portion of the lifting hook and closes the opening of the lifting hook.

Among the above-mentioned hoist mousing-hook and prevent mistake hook wire rope device technical scheme, more specific technical scheme can also be: arc baffle's upper end be equipped with positioning bolt articulated otic placode portion, otic placode portion is equipped with the bolt hole, arc baffle's lower extreme is equipped with and pastes tightly the portion of bending in the lifting hook point portion outside.

Furthermore, an included angle a between the connecting rod and the closing plate is 120 degrees.

Since the technical scheme is used, compared with the prior art, the utility model following beneficial effect has:

1. the utility model discloses be equipped with the balancing weight through the connecting rod on the upper portion of closing plate, adopt the gravity lever principle, make the free end of closing plate keep closing the state of lifting hook mouth, connecting rod and balancing weight are difficult to warp the damage, and the greatly reduced leads to the condition of warp inefficacy because of the collision, and anti collision ability is high, long service life. The arc-shaped baffle is hinged to the positioning bolt, the free end of the arc-shaped baffle is kept in a state of closing the hook opening, and the arc-shaped baffle is used for a double-hook crane with a main hook and an auxiliary hook, so that when the main hook is used for lifting goods and stabilizing hooks, the auxiliary hook is prevented from mistakenly hooking a steel wire rope of the main hook.

2. The upper end of the arc-shaped baffle plate is provided with an ear plate part hinged with the positioning bolt, and the ear plate part is provided with a bolt hole; the lower extreme of cowl is equipped with the portion of bending that pastes the tight lifting hook point portion outside, avoids the lifting hook to buckle wire rope into, and work safe and reliable.

3. The included angle a between the connecting rod and the closing plate is 120 degrees, so that the closing plate is further ensured to be in a state of closing the hook opening in the working process.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The invention will be described in more detail with reference to the following embodiments:

fig. 1 shows a hoist mousing-hook and prevent mistake hook wire rope device, include with wear to adorn in the closing plate 1 of the 3 articulated of positioning bolt of lifting hook handle, the free end of closing plate 1 is located the lifting hook point portion inboard and closes the lifting hook mouth, the welding of connecting rod 4 is passed through on the upper portion of closing plate 1 has balancing weight 5, balancing weight 5 adopts the iron plate, the contained angle a between connecting rod 4 and the closing plate 1 is 120 degrees. An arc-shaped baffle plate 2 is hinged to the positioning bolt 3, and the free end of the arc-shaped baffle plate 2 is positioned on the outer side of the tip part of the lifting hook and closes the opening of the lifting hook. The upper end of cowl 2 has the otic placode portion articulated with positioning bolt 3, and the bolt hole has been seted up to otic placode portion, and cowl 2's lower extreme has the portion of bending that pastes the tight lifting hook point portion outside.

The utility model discloses when needing to hang wire rope to the lifting hook, with cowl 2 around 3 clockwise rotations of positioning bolt, push away switch and close cowl 2 in the lifting hook mouth outside, wire rope promotes closure plate 1 around 3 counter-clockwise rotations of positioning bolt to hang into in the lifting hook. Because the balancing weight 5 is welded on the upper part of the closing plate 1 through the connecting rod 4, the gravity lever principle is adopted, so that the free end of the closing plate 1 is kept in a state of closing a hook opening, the connecting rod 4 and the balancing weight 5 are not easy to deform and damage, the condition of deformation and failure caused by collision is greatly reduced, the anti-collision capacity is high, and the service life is long. Articulated on positioning bolt 3 have cowl 2, and cowl 2's free end keeps closing the state of lifting hook mouth for there is the double hook hoist of main and auxiliary hook, when using the stable hook of main hook handling goods, prevents that auxiliary hook from hooking by mistake main hook wire rope.

A1780 hot rolling plant of Guangxi Steel group Co Ltd, a finished product warehouse double-hook crane, which uses a traditional unhooking prevention device, is easily damaged by collision and deformation when unhooking and re-installing a lifting tool, the time for dismounting, repairing and correcting 1 piece per day is about 15min, and when lifting goods, an auxiliary hook is easily swung to hook a main hook steel wire rope, 2-3 times per day, and the processing time is about 3 min. The double-hook crane in 2021 year uses this hoist mousing-hook and prevents mistake hook wire rope device, has improved the device's life greatly, and when taking place great striking, the positioning bolt 3 and the damage of connecting rod 4 just need be changed to thoroughly solved when using the stable hook of main hook handling goods, the problem of main hook wire rope is caught in the mistake to vice lifting hook, effectively reduced the fault time of hoist, ensured the safe handling of hoist.
