Abstract

The utility model relates to an unhooking-proof safety device of a crane hook, belonging to the technical field of mechanical equipment. The technical scheme is as follows: the unhooking-proof safety device comprises a baffle (1), a pin shaft (2), a steel sleeve (3), a balance weight lever (4) and a hook (5), wherein the steel sleeve is fixed on the inner side of a hook opening of the hook and the length of the steel sleeve is matched with the thickness of the hook; the pin shaft is arranged in the steel sleeve; the baffle and the balance weight lever are U-shaped; the two sides of an opening end of the U-shaped baffle are connected with the pin shaft; the length of the U-shaped baffle is matched with that of the hook opening of the hook; the U-shaped balance weight lever is arranged on the outer side of the hook opening of the hook; the two sides of the opening end are connected with the pin shaft. According to the unhooking-proof safety device provided by the utility model, the balance weight lever enables the baffle to baffle the hook opening of the hook under the effect of gravity so as to prevent a steel rope from being released. The unhooking-proof safety device of the crane hook provided by the utility model has the beneficial effects of simple structure, convenience in operation, no need of any external force, collision resistance and long service life.

Description

A kind of crane hook lock hook safety device

Technical field

The utility model relates to a kind of crane hook lock hook safety device, especially prevents trip mechanism, belongs to mechanical equipment technical field.

Background technology

Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods, claims again crane, belongs to material carrying machine.The work characteristics of hoisting crane is to do intermittent exercise, and namely the corresponding mechanism of the actions such as feeding, migration, unloading in a working cycle, be alternation.

Hoisting crane mainly comprises lifting mechanism, operating unit, luffing mechanism, swing type mechanism and metal construction etc.Lifting mechanism is the groundwork mechanism of hoisting crane, mostly hangar system and winch, consists of, and also has by hydraulic efficiency pressure system lifting weight.Operating unit, in order to the control position of vertical equity migration weight or adjustment hoisting crane, generally is comprised of electrical motor, retarder, drg and wheel.Luffing mechanism only is provided on jib-type crane, and when jib was steeved, amplitude reduced, and while bending down, amplitude increases, two kinds of balance-dividing luffing and non-equilibrium luffings.Swing type mechanism, with so that jib turns round, is comprised of actuating device and rotary supporting device.Metal construction is the skeleton of hoisting crane, and main load member such as crane span structure, jib and door frame can be box type construction or truss structure, also can be web structure, and the available shaped steel had is as support beam.

Suspension hook is modal a kind of suspender in elevator machinery.Suspension hook often is suspended on the steel rope of lifting mechanism by means of parts such as assembly pulleys.In routine inspection, often find that the suspension hook of weight-lifting equipment lacks Anti-hook releasing device, some gross distortions, some pull back springs lost efficacy or damaged, and lost the anticreep effect.Like this, stayed aborning potential safety hazard, hoist cable unhook phenomenon easily occurred, caused that weight falls, the accident of personal casualty.

The utility model content

The utility model purpose is to provide a kind of crane hook lock hook safety device, and the effect that takes full advantage of self gravitation makes baffle plate block the suspension hook mouth of hook, prevents that steel cable from deviating from, and solves the problem existed in background technology.

The technical solution of the utility model is:

A kind of crane hook lock hook safety device, comprise baffle plate, bearing pin, steel bushing, weight linear meter, suspension hook, steel bushing is fixed on suspension hook mouth of hook inboard, length and suspension hook thickness are complementary, and bearing pin is placed in steel bushing, and baffle plate and weight linear meter are U-shaped, U-shaped baffle openings end both sides connect bearing pin, length and the suspension hook mouth of hook are complementary, and U-shaped weight linear meter is placed in the suspension hook mouth of hook outside, and the open end both sides connect bearing pin.

Its angle of described weight linear meter be weight linear meter while being down to bottom dead point baffle plate block the suspension hook mouth of hook.

Weight linear meter makes baffle plate block the suspension hook mouth of hook under Action of Gravity Field, stop steel cable to be deviate from.When the dislodging steel cable, lift weight linear meter drive baffle plate and pack up, steel cable can free in and out.

The beneficial effects of the utility model are: the effect that takes full advantage of self gravitation makes baffle plate block the suspension hook mouth of hook, prevents that steel cable from deviating from, simple in structure, easy to operate, without by any external force, and also anti-colliding with, long service life.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation;

In figure: baffle plate 1, bearing pin 2, steel bushing 3, weight linear meter 4, suspension hook 5.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail by example.

With reference to accompanying drawing 1, a kind of crane hook lock hook safety device, comprise baffle plate 1, bearing pin 2, steel bushing 3, weight linear meter 4, suspension hook 5, one of processing φ 15x2.5 steel bushing, the length outline is wider than suspension hook thickness, be weldingly fixed on suspension hook mouth of hook inboard, make one of φ 9.5 bearing pin, be placed in steel bushing, the length equalization of steel bushing is exposed at two ends, baffle plate and weight linear meter are U-shaped, Weir Plate Thickness 6mm, width is equal to bearing pin, length can guarantee to freely swing in the suspension hook mouth of hook, with mouth of hook gap in about 1mm, U-shaped baffle openings end both sides connect bearing pin, it is U-shaped that to join the heavy diameter of bar be 10mm, be placed in the suspension hook mouth of hook outside, the open end both sides connect bearing pin, the weight linear meter angle be weight linear meter while being down to bottom dead point baffle plate block the suspension hook mouth of hook.Weight linear meter makes baffle plate block the suspension hook mouth of hook under Action of Gravity Field, stop steel cable to be deviate from.When the dislodging steel cable, lift weight linear meter drive baffle plate and pack up, steel cable can free in and out.
