Description

Lifting hook for lifting steel plate

Technical Field

The utility model relates to a lifting hook, in particular to lifting hook for handling steel sheet.

Background

The steel plates are generally heavy and difficult to transport manually, and often need to be hoisted by means of hoisting tools. When the steel plate is hoisted, the lifting hook is often directly hooked around the steel plate and then hoisted. The connecting position of the lifting hook and the steel plate needs to be set in advance so as to ensure that the steel plate can keep balance in the lifting process. But at actual handling in-process, the lifting hook produces relative slip with the steel sheet easily, leads to the lifting hook skew original position of setting for, leads to the steel sheet to lose balance and drop, injures the staff on the scene easily by a crashing object, consequently has great potential safety hazard.

For example, chinese patent publication No.: CN205114827U, utility model's name is a steel sheet lifting hook, including the crotch, the crotch includes fixed part, baffle portion and bearing part, and the top of fixed part is established

The lower end of the fixing part is connected with one end of the baffle part, the other end of the baffle part is connected with the lower end of the bearing part, the internal angle between the fixing part and the baffle part is 100-120 degrees, and the internal angle between the baffle part and the bearing part is 80-90 degrees. This steel sheet lifting hook is at the handling in-process, and the lifting hook produces relative slip with the steel sheet easily, leads to the lifting hook skew original position of setting for, leads to the steel sheet to lose balance and drop, injures the staff on the scene by a crashing object easily, consequently has great potential safety hazard.

Disclosure of Invention

The utility model aims at solving current lifting hook when the handling steel sheet, the lifting hook produces relative slip easily and steel sheet and makes the skew original position of setting for of lifting hook lead to the steel sheet to lose balance and drop, injures the problem of the staff on the scene by a crashing object easily, provides a lifting hook for handling steel sheet, can effectively solve above-mentioned problem.

The utility model aims at realizing through the following technical scheme: the utility model provides a lifting hook for handling steel sheet, includes the lifting hook body, be provided with the electro-magnet on the contact surface of lifting hook body and steel sheet, still be provided with on the lifting hook body and be used for compressing tightly the hold-down mechanism to the steel sheet.

When the lifting hook body hooks the steel sheet, the electromagnet can be adsorbed on the surface of the steel sheet, and the pressing mechanism can press the steel sheet on the lifting hook, so that the lifting hook body is firmly fixed with the steel sheet, the steel sheet is not easy to deviate from the originally set position in the lifting process, the steel sheet is more stable in the lifting process, and the safety is higher.

Preferably, a groove matched with the electromagnet is formed in the contact surface of the lifting hook body and the steel plate, the electromagnet is embedded in the groove, and the upper surface of the electromagnet is flush with the contact surface.

Preferably, the pressing mechanism comprises a sliding hole arranged on the hook body, the axial direction of the sliding hole is perpendicular to the contact surface, a sliding rod is connected in the sliding hole in a sliding manner, a pressing plate is arranged at one end, close to the electromagnet, of the sliding rod, and the pressing plate is opposite to the electromagnet; and a spring is arranged between one side of the pressing plate, which is far away from the electromagnet, and the lifting hook body. Before the lifting, the sliding rod is pulled to enable the pressing plate to be far away from the electromagnet, the steel plate is convenient to place between the pressing plate and the electromagnet, then the sliding rod is loosened, and the pressing plate automatically compresses the steel plate under the action of the spring, so that the steel plate is firmly fixed on the lifting hook.

Preferably, a sliding bearing is arranged between the sliding hole and the sliding rod. The sliding bearing can reduce the frictional resistance between the sliding rod and the sliding hole.

Preferably, a rubber pad is arranged at one end of the pressing plate close to the electromagnet. On one hand, the rubber pad is soft, so that scratches on the surface of the steel plate caused by direct contact between the pressing plate and the steel plate can be avoided; on the other hand, the rubber pad can increase the friction force between the steel plate and the rubber pad, so that the steel plate is not easy to slide relatively between the pressing plates.

Preferably, one end of the sliding rod, which is far away from the pressure plate, is provided with a limiting head, and the diameter of the limiting head is larger than that of the sliding hole. The limiting head plays a limiting role and prevents the sliding rod from separating from the sliding hole.

Preferably, one end of the lifting hook body is provided with a shackle. The shackle is used for facilitating the installation and the disassembly of the lifting hook.

The utility model has the advantages that: the utility model discloses can make the steel sheet firmly fix on the lifting hook at the handling in-process, effectively avoid the steel sheet at handling in-process from the lifting hook landing, improve the security of steel sheet at the handling in-process.
