Description

Crane hook

Technical Field

The utility model relates to a crane hook, use on the hoist of specially adapted high-lift hoisting mechanism's hoisting mechanism.

Background

The crane hook is the most common lifting appliance in the hoisting machinery, the hook is usually hung on a steel wire rope of a hoisting mechanism in a series connection mode by means of a pulley block and other components, under some special conditions, the crane often needs a large hoisting height to meet normal use, as is well known, the rotation of the steel wire rope can enable the hook below the steel wire rope to rotate to a certain degree due to the self rotation stress, and particularly when the hoisting height is large, the rotation can be amplified, the steel wire rope is twisted and knotted, the crane cannot normally work, and an inestimable result is generated.

The national patent office grant publication No. CN209635729U, the name "a crane hook structure", including the assembly pulley, the assembly pulley adopts three movable pulley structures of group, set up the dog in the assembly pulley, set up wire rope on the movable pulley, hanger plate A and hanger plate B have been connected respectively to the assembly pulley upper end, hanger plate A and hanger plate B adopt symmetrical structure, hanger plate A and hanger plate B pass through wire rope and connect electric block, the hoist yoke plate has been connected at hanger plate A and hanger plate B lower extreme, hanger assembling plate and supporting beam have set gradually from top to bottom in the hoist yoke plate, hang the lifting hook in a supporting beam lower extreme weak point, it is, this assembly pulley is the tandem system, when lifting cargo, especially when high-lift lifting height, the lifting hook is easily swung from side to side, wire rope twists reverse and ties.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an increase antitorque moment, resist the produced torque of wire rope, can effectively avoid wire rope to twist reverse a crane hook who knoes when big lifting height.

The utility model discloses a task is accomplished like this, including lifting hook, lifting hook nut, reel, wire rope, running block, the gallows is double, and double gallows neutral department has welded the lifting hook crossbeam, and running block installs respectively on four angles of gallows, and the lifting hook penetrates through the fastening of lifting hook nut in the lifting hook crossbeam, and the lifting hook nut passes through thrust bearing to be fixed to the lifting hook crossbeam on, and the lifting hook crossbeam minor axis passes through the cardboard to be fixed on the perpendicular baffle in both sides area U type groove. The lifting hook comprises a lifting hook beam, a lifting hook beam and two vertical partition plates with U-shaped grooves, wherein the two vertical partition plates are connected in parallel, the lifting hook beam is connected with the lifting hook beam, the lifting hook beam is provided with a lifting hook beam, and the lifting hook beam is provided with a lifting hook beam. Two steel wire ropes respectively coming down from the winding drum pass through the movable pulley block on the left side of the hanging bracket and upwards bypass the fixed pulley block of the trolley, then bypass the movable pulley block on the right side of the hanging bracket, and finally connect the steel wire ropes to the balancing device of the trolley.

The utility model discloses has following effect: adopt the novel lifting hook group of double parallelly connected pulley, change the pulley arrangement on the lifting hook into double parallelly connected arrangement by establishing ties, arrange respectively on four angles on the lifting hook frame, increase the distance between pulley and the pulley, be equivalent to 4 hoisting points and lift jointly and hang, increased the stability of lifting hook group, rely on the stability of lifting hook to resist the rotational stress that wire rope produced, prevent that wire rope from twisting to tie a knot, satisfy normal work production.

Fig. 1 is a schematic structural diagram of the present invention; FIG. 2 is a side view of FIG. 1; FIG. 3 is a top view of FIG. 1; fig. 4 is a schematic view of the working state structure of the present invention.

Description of the drawings: 1. the device comprises a movable pulley block, 2, a hanging bracket, 3, a lifting hook, 4, a lifting hook cross beam, 5, a lifting hook nut, 6, a winding drum, 7, a steel wire rope, 8, a fixed pulley block, 9 and a balancing device.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The utility model discloses a novel lifting hook group of double parallelly connected pulley arranges through the jumbo size of pulley, and increase anti-rotation moment resists the produced torque of wire rope, can effectively avoid wire rope to twist reverse when big lifting height and tie a knot, guarantees the hoist and normally works.

The specific embodiment is shown in fig. 1, fig. 2 and fig. 3, the crane hook comprises a hook 3, a hook nut 5, a winding drum 6, a steel wire rope 7, a movable pulley block 1 and a hanger 2 which are double rows, hook cross beams 4 are welded at the positions of the double rows of hanger neutral positions, the movable pulley block 1 is respectively installed on four corners of the hanger, the hook 3 penetrates into the hook cross beams and is fastened through the hook nut 5, the hook nut 5 is fixed on the hook cross beams through a thrust bearing, short shafts of the hook cross beams are fixed on vertical partition plates with U-shaped grooves on two sides through clamping plates, and the hook can swing left and right in the U-shaped grooves.
