Abstract
The invention relates to a double-hook rope catch device, in particular to a double-hook rope catch device used for a crane lifting hook with the shape like the Chinese character of 'shan' for preventing a steel wire rope from dropping from the inside of a hanging part, belonging to the technical field of hoisting machinery. The double-hook rope catch device comprises stop backs, a hinge pin, a spring and a bracket, wherein two stop backs are connected and fastened with the bracket by the hinge pin and the spring to form an integral bracket assembly; two groups of integral bracket assemblies are fastened on the neck of the lifting hook by bolts, nuts and a spring washer; and the position thereof ensures that two stop backs can be effectively placed on the neck of a hook slot. The invention has simple, compact and reasonable structure, safe and reliable operation and convenient installation and disassembly; because the spring acts on the steel wire rope, the hook is convenient to put in, and two stop backs can effectively prevent the steel wire hook on the lifting hook with the shape like the Chinese character of 'shan' from slipping.
Description
Technical field
The present invention relates to a kind of double-hook rope catch device, specifically be used for being used for preventing on the word suspension hook of hoisting crane mountain steel rope slippage in the hanging part, belong to the elevator machinery technical field.
Background technology
At present, in view of suspension hook operation purposes, by steel rope or the work of special hanger starting parcel series.But because operation operating mode and lift heavy thing is different, steel rope some the time phenomenon that breaks off relations always appears, for job safety and operating efficiency hide some dangers for.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of double-hook rope catch device safely and effectively is provided, safe and reliable, effectively prevent the slippage of steel rope on the word suspension hook of mountain.
According to technical scheme provided by the invention, double-hook rope catch device comprises block back, bearing pin, spring, support, earlier with two block backs by bearing pin and spring connect with support, fastening composition integral support assembly, again two groups of integral support assemblies are fastened on suspension hook neck place by bolt, nut, spring washer, its position should can effectively be placed on hook groove neck with two block backs.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Safe and reliable, be convenient to installing/dismounting; It very is convenient going into hook because of the action of the spring steel rope, and two block backs can effectively prevent the slippage of steel rope on the word suspension hook of mountain.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, the present invention mainly is made of jointly block back 1, bearing pin 2, spring 3, support 4, bolt 5, nut 6, spring washer 7.
The present invention is in operation, two block backs 1 are passed through bearing pin 2 in elder generation and spring 3 connects with support 4, fastening composition integral support assembly, again two groups of integral support assemblies are fastened on suspension hook neck place by bolt 5, nut 6, spring washer 7, its position should can effectively be placed on hook groove neck with two block backs 1.Only need stressedly gently block back can be pressed from suspension hook hook groove neck when putting into steel rope in steel cable, make steel rope have the space to enter the suspension hook coupler body, this moment, block back was that counter-force props up hook groove neck under action of the spring, when sliding outward as if steel rope is stressed, block back also props up hook groove neck inflexibly, stops it outer sliding.When steel rope is taken out, only need to eliminate the steel rope tensile force, press block back gently, just steel rope can be taken out.
