Abstract
The utility model belongs to the field of crane machinery manufacturing, and particularly relates to a lifting hook and a crane with the same. The lifting hook is characterized by also comprising a baffle which consists of a pivoting end and a free end, wherein the pivoting end is pivoted with a baffle installation seat, is hollow, and is internally provided with parallel groove channels; openings of the groove channels are provided with backstop bulges; the end, which is close to the baffle installation seat, of the pivoting end is provided with at least one spring; one end of the free end is sleeved with the pivoting end, and is connected with the springs; two sides of the free end are provided with backstop blocks; the backstop blocks and the parallel groove channels are matched; the other end of the free end is provided with a through hole; the outer side of the hook part of a lifting hook body is provided with a clamping groove matched with the through hole in the free end. The lifting hook has the advantages that the lifting hook is novel in concept and compact and reasonable in structure; the free end of the baffle can slide in the pivoting end; the baffle has a dropping prevention function; a lifting rope is convenient and rapid to install in the lifting hook or take down from the lifting hook, time and labor are saved, and the working efficiency is improved.
Description
Technical field
The utility model relates to hoisting crane technical field, specifically belongs to suspension hook and has the hoisting crane of this suspension hook.
Background technology
In prior art, conventional suspension hook has the anti-drop function that prevents that lifting rope from deviating from from holding the inner space of lifting rope.Opening one side of the suspension hook body coupling end of suspension hook has been installed baffle plate mount pad, baffle plate comprises the hub switch side and the free end that are oppositely arranged, hub switch side is arranged on baffle plate mount pad by bearing pin, free end can rotate around bearing pin, torsion spring acts on respectively suspension hook body and baffle plate, and under the effect of torsion spring, the free end of baffle plate is close on the inwall of suspension hook body, thereby make baffle plate sealing opening, prevent that lifting rope from breaking off relations.Defect is, because baffle plate is close on the inwall of suspension hook body, when taking out or change lifting rope, need artificially baffle plate to be depressed towards the direction of the inner space of suspension hook body, also when taking out or packing lifting rope into, in order to open the opening of suspension hook, need apply the twisting resistance that a power applies baffle plate with opposing torsion spring to baffle plate; Lifting rope is heavy, needs two people to operate just and can complete, waste time and energy, and inefficiency.
Utility model content
The purpose of this utility model has been to provide jib boom bearing pin, a kind of suspension hook and there is the hoisting crane of this suspension hook, and suspension hook is simple in structure, not only there is anti-drop function, and lifting rope packs suspension hook into or convenient and swift, time saving and energy saving when suspension hook takes off, increase work efficiency.
The technical solution adopted in the utility model is as follows:
A kind of suspension hook, comprises suspension hook body, holds inner space and the opening of lifting rope; Baffle plate mount pad, be positioned at one end of suspension hook body upper shed, it is characterized in that: this suspension hook also comprises baffle plate, described baffle plate is comprised of hub switch side and free end, hub switch side and the pivot joint of baffle plate mount pad, hub switch side is hollow form, inside establishes parallel channel, groove channel port is established stopper protrusion, and at least one spring is established near baffle plate mount pad end in hub switch side; Free-ended one end is sleeved in hub switch side, is connected with spring, and stop block is established in both sides, and stop block matches with parallel channel, and the other end has through hole; The hook portion outside of described suspension hook body is provided with a draw-in groove, matches with free-ended through hole.
Described through hole ovalize.
Described draw-in groove cross section is square, and draw-in groove is offered angle horizontal by 60 ° of angles.
A kind of hoisting crane, this hoisting crane comprises suspension hook, described suspension hook is according to the suspension hook described in any one in claims 1 to 3.
Compared with prior art, advantage is: this suspension hook is novel, and structure letter gathers, rationally, the free end of baffle plate can slide in hub switch side, and baffle plate has anti-drop function, and lifting rope packs suspension hook into or be convenient and swift when suspension hook takes off, time saving and energy saving, increase work efficiency.

Fig. 1 is the structural representation of suspension hook;
Fig. 2 is the utility model baffle arrangement schematic diagram.
In figure: 1-suspension hook body, 2-baffle plate mount pad, 3-baffle plate, 4-hub switch side, 5-free end, 6-through hole, 7-draw-in groove, 8-spring, 9-parallel channel, 10-stopper protrusion, 11-stop block.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further described.
By Fig. 1,2, can be found out, a kind of suspension hook, comprises suspension hook body 1, holds inner space and the opening of lifting rope; Baffle plate mount pad 2, is positioned at one end of suspension hook body upper shed; This suspension hook also comprises baffle plate 3, and described baffle plate is comprised of hub switch side 4 and free end 5, hub switch side and the pivot joint of baffle plate mount pad, and hub switch side is hollow form, inside establishes parallel channel 9, and groove channel port is established stopper protrusion 10, and two springs 8 are established near baffle plate mount pad end in hub switch side; Free-ended one end is sleeved in hub switch side, is connected with spring, and stop block 11 is established in both sides, and stop block matches with parallel channel, and the other end has elliptical hole 6; The hook portion outside of described suspension hook body is provided with a draw-in groove 7, and draw-in groove cross section is square, and draw-in groove is offered angle horizontal by 60 ° of angles, matches with free-ended elliptical hole.
A kind of hoisting crane, this hoisting crane comprises suspension hook, the suspension hook of this hoisting crane adopts above-mentioned suspension hook of the present utility model.
