Description
Technical field
The utility model belongs to suspension hook technical field, is specifically related to a kind of safety device, particularly a kind of load hook safety device.
Background technology
Load hook is when lifting operation, because many reasons may cause the Current Collector Sleave on suspension hook to break off relations, and the crane walking mistiming person of hurting sb.'s feelings, therefore certain Anti-hook releasing device must be done to suspension hook gib head, to prevent the generation of such accident, at present for the measure of suspension hook lock hook, common way uses the compositions such as baffle plate, spring and pin, spring force is relied on to keep the position of baffle plate, prevent Current Collector Sleave from breaking off relations, but baffle plate and spring can deform or damage under larger External Force Acting, and service life is also short; Therefore, provide a kind of rational in infrastructure, easy and simple to handle, safety is good, the load hook safety device of long service life is necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of rational in infrastructure, easy and simple to handle, safety is good, the load hook safety device of long service life
The purpose of this utility model is achieved in that a kind of load hook safety device, it comprises suspension rod, the lower end of described suspension rod is connected with suspension hook, described suspension rod bottom is provided with crossbeam, the described crossbeam left and right sides is provided with bolt, spring A is provided with on the downside of described crossbeam left part, described crossbeam right part is provided with rotating shaft, described rotating shaft is connected with connecting rod, the left end of described connecting rod is connected to the lower end of spring A, the bar of described connecting rod right part arranges porose and lid, the downside in described hole is connected with spring B, the inside of described spring B is provided with bar, the lower end of described spring B and the lower end of bar are all connected on suspension hook.
Described bolt is 2.
Described connecting rod is right angle connecting rod.
Described spring A and spring B are coil spring.
Described lid is circular lid.
Described hole is cylindrical hole.
Described bar is cylinder body rod.
The beneficial effects of the utility model: the utility model adopts connecting rod and rotating shaft, when suspension hook lifting object, press connecting rod downwards, connecting rod left part upward movement can be made, thus suspender can be put into suspension hook, after suspension hook put into by suspender, can rely on the elastic force of lid and the spring that connecting rod is arranged that suspension hook is closed by connecting rod, ensure that the safety of Current Collector Sleave in suspension hook; The utility model adopts two springs, makes this safety device better relative to traditional safety device safety, adopts connecting rod and bar, simple and reasonable, easy and simple to handle, and long service life; The utility model have rational in infrastructure, easy and simple to handle, safety is good, the advantage of long service life.
