Technical Field

The invention belongs to the technical field of hoisting machinery, and particularly relates to a crane hook capable of monitoring and preventing breakage in real time.

Background

In the fields of industrial production, building production and the like, a crane is often used for lifting a heavy object, the heavy object is hung on a lifting hook of the crane through a hook, then the crane is operated to lift the heavy object, the lifting hook generally comprises an upper straight edge section and a lower bent hook section, the mass of the heavy object acts on the lowest point of the bent hook through a steel wire rope, the vertical end surface of the lowest point of the bent hook is mainly subjected to the action of shearing stress and combined tension and bending stress, the heavy object has the pulling force and shearing force on the lifting hook and also has the tendency of straightening the lifting hook, therefore, the horizontal section of the side wall of the bent hook is not only subjected to the pulling force of the weight of the heavy object, so that the whole section is subjected to the tension stress, but also subjected to the moment, under the action of the pulling stress on the inner side of the section of the side wall, and under the action of the compression stress on the outer side, so that the bottom section and, also known as the hazard section, the hook is most susceptible to breakage at these two locations.

In the in-process of lifting by crane the heavy object, in case take place the cracked condition of lifting hook, will cause serious incident, at present, all there is not the real-time supervision device of lifting hook on most hoist, people adopt the method of preventing in advance, avoid the lifting hook fracture in the course of the work through carrying out periodic inspection to the lifting hook, but during twice inspection interval, the cracked condition of lifting hook also can appear, there is the potential safety hazard, for example in the harbour operation, factors such as wind-force among the external environment lead to the lifting hook to rock easily, the corruption of lifting hook also can aggravate in strong wind and heavy rain weather, these proruption have increased the wearing and tearing of lifting hook and cracked possibility, and operating personnel can't know the particular case of lifting hook again this moment, continue to use the lifting hook to carry out the work, cause the production incident very.

Therefore, in view of the above, research and improvement are made for the existing structure and defects, and a crane hook capable of monitoring and preventing breakage in real time is provided, so as to achieve the purpose of higher practical value.

Disclosure of Invention

In order to solve the technical problems, the invention provides a crane hook capable of monitoring and preventing breakage in real time, so as to solve the problem that the crane hook is not provided with a real-time detection device and has potential safety hazards.

The invention relates to a purpose and an effect of a crane hook capable of monitoring and preventing breakage in real time, which are achieved by the following specific technical means:

the utility model provides a but cracked crane hook of real-time supervision prevention, includes the lifting hook main part, the fixed ring seat that has cup jointed in the outside of the straight limit section of lifting hook main part, the bottom of ring seat just is located the outside fixedly connected with fixing base of the hook main part crotch section, the inside sliding connection of fixing base has the fly leaf, the inside activity hinge of fixing base has evenly distributed's pick-up plate, install the extension spring on the pick-up plate, the left side activity hinge of ring seat has the connecting rod, the below activity hinge of connecting rod has the lifter plate that extends to the fixing base inside, the lifter plate passes through roller and fly leaf swing joint, the inside fixedly connected with guide holder of ring seat, the top activity hinge of connecting rod has the picture peg that extends to the guide holder top, the top fixedly connected with baffle of picture peg, the inside of ring seat just is located the right side, the outer side of the ring seat is fixedly embedded with a transparent box, the interior of the transparent box is filled with a fluorescent material, the inner top wall on the left side of the transparent box is fixedly connected with a sealing tube, and the interior of the sealing tube is filled with reaction liquid.

Further, the top and the bottom of fixing base all with lifting hook main part fixed connection, leave the clearance between the middle section of fixing base and the lifting hook main part, this clearance is in order to detect the lifting hook main part deformation condition before the crack fracture appears.

Further, the shape of fly leaf corresponds with the crotch section of lifting hook main part, can detect the deformation condition of lifting hook main part better.

Further, the left side of pick-up plate extends to the inside of fly leaf, the right side of pick-up plate extends to the outside of fixing base, and the through-hole that corresponds with the pick-up plate has all been seted up to the inner wall of fixing base and the inside of fly leaf.

Further, the pick-up plate passes through the articulated shaft to be installed on the fixing base, the articulated shaft department of pick-up plate is kept away from with the junction of pick-up plate to the extension spring, the extension spring is located the left side of pick-up plate articulated shaft, and under the pulling force effect of extension spring, the right-hand member of pick-up plate supports on the outer wall of lifting hook main part crotch section, utilizes lever principle, and the pick-up plate can give the amplification with the small deformation of lifting hook main part crotch section.

Furthermore, the connecting rod is installed on the ring seat through a hinged shaft, the joint of the lifting plate and the connecting rod is close to the hinged shaft of the connecting rod, and the connecting rod can amplify the displacement of the lifting plate by utilizing the lever principle.

Furthermore, a pressure spring is arranged on the impact rod, a through hole corresponding to the impact rod is formed in the baffle and below the impact rod, and after the baffle moves upwards, the impact rod can penetrate through the through hole to impact on the transparent box under the pushing of the pressure spring.

Furthermore, the transparent box is placed in an inclined shape and made of hard transparent materials, and the inner left wall of the transparent box is provided with a flexible section corresponding to the impact rod, so that after the sealed tube is broken by the impact rod, the reaction liquid can better react with the fluorescent material to emit light.

Advantageous effects

Compared with the prior art, the invention has the following beneficial effects:

1. before cracks and fractures appear on the hook main body, tiny deformation can be generated firstly, the deformed hook main body extrudes the detection plate, the tiny deformation of the hook main body is amplified through the lever action of the detection plate, the movable plate can drive the lifting plate to move upwards, the moving displacement of the lifting plate is further amplified through the lever action of the connecting rod, therefore, the inserting plate can drive the baffle plate to move upwards for a large distance, the impact rod penetrates through the through hole under the pushing of the pressure spring to impact on the flexible section of the transparent box and further impact on the sealing pipe to break the sealing pipe, reaction liquid in the sealing pipe flows down to contact with fluorescent materials and react to generate light rays, the warning reminding is carried out on an operator, the operator is reminded that the hook is deformed and needs to be checked, and the situation that the operator continues to use the hook to lift heavy objects under the unknown situation is avoided, causing a safety accident.

2. Through designing into the slope form with transparent box, can make the better flow of reaction liquid and react with phosphor, final transparent box whole circle all can give out light, guarantees that operating personnel can both observe at which angle, and it is more convenient to use.

3. The device adopts a light early warning method, and compared with a general sound early warning method, the device reduces vibration, further improves the stability and the safety of the lifting hook, and simultaneously avoids the problem that sound alarm cannot be clearly received due to large environmental noise in the working process, so that the device is more convenient to use and is safe and reliable.
