Abstract
The utility model belongs to the field of mechanical manufacturing of cranes and in particular relates to a lifting hook and a crane with the same. The lifting hook is characterized in that a groove is formed in a lifting hook body and opposite to the lower side of a baffle mounting seat; the lifting hook also comprises a baffle; the baffle consists of a pivoting end and a free end; the hollow pivoting end is pivoted to the baffle mounting seat, and parallel channels are formed in the pivoting end; openings of the channels are provided with stop bulges; at least one spring is arranged at a position, which is close to the baffle mounting seat, of the pivoting end; one end of the free end is arranged in the pivoting end in a sleeved manner and is connected with the spring, stop blocks are arranged on two sides of the free end and are matched with the parallel channels, and a through hole is formed in the other end of the free end; a clamping slot is formed in the outer side of the hook part of the lifting hook body and is matched with the through hole of the free end. The lifting hook has the advantages of novel concept and compact and reasonable structure; the free end of the baffle can slide in the pivoting end; the baffle has an anti-falling function; a lifting rope can be conveniently and quickly arranged into the lifting hook or taken out of the lifting hook, so that time and labor are saved, and the working efficiency is improved.
Description
Technical field
The utility model belongs to hoisting crane mechanical manufacturing field, relates in particular to a kind of 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, in the time 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 in 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
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of suspension hook and has 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.
A kind of suspension hook, comprises suspension hook body, holds inner space and the opening of lifting rope; Baffle plate mount pad, is positioned at one end of suspension hook body upper shed, is characterized in that described suspension hook body has a groove with respect to the lower position of baffle plate mount pad; This suspension hook also comprises baffle plate, and described baffle plate is made up of hub switch side and free end, hub switch side and the pivot joint of baffle plate mount pad, and hub switch side is hollow form, inside establishes parallel channel, and 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.
The utility model further improves, and the length of described parallel channel is that hub switch side is to 1/3 of suspension hook body distal-most end distance.
The utility model further improves, and described through hole is rectangle, and width is greater than the diameter of section of suspension hook body.
The utility model further improves, and described draw-in groove cross section is square, and draw-in groove is offered angle horizontal by 60 ° of angles.
The utility model also provides a kind of hoisting crane, and this hoisting crane comprises suspension hook, and described suspension hook is above-mentioned suspension hook of the present utility model.
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.
Accompanying drawing explanation
Fig. 1 is the structural representation of suspension hook;
Fig. 2 is a kind of constitution diagram that uses of the present utility model;
Fig. 3 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-groove, 9-spring, 10-parallel channel, 11-stopper protrusion, 12-stop block.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is further described.
Can be found out by Fig. 1,2, 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; Suspension hook body has a groove 8 with respect to the lower position of baffle plate mount pad; This suspension hook of this suspension hook also comprises baffle plate 3, and described baffle plate is made up of hub switch side 4 and free end 5, hub switch side and the pivot joint of baffle plate mount pad, hub switch side is hollow form, inside establish parallel channel 10, groove channel port is established stopper protrusion 11, and two springs 9 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 12 is established in both sides, and stop block matches with parallel channel, and the other end has rectangular through holes 6, and the width of through hole is greater than the diameter of section of suspension hook body; 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 rectangular through holes.
Can be found out by Fig. 2,3, the length of parallel channel 10 is that hub switch side 4 is to 1/3 of suspension hook body 1 distal-most end distance.
When work, as shown in Figure 1, free end, due to the pulling force of spring, fastens the head draw-in groove of free-ended through hole and suspension hook body, and lifting rope packs suspension hook into, seals the opening of suspension hook, has anti-avulsion effect; As shown in Figure 2, free end around the opposite side to suspension hook body, fits the bottom of hub switch side and groove from hook portion, and now, lifting rope is easy to take out.
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.
