Description
Technical Field
The utility model relates to a lift by crane the subassembly field, especially relate to a nipper is used in forging shop.
Background
In the hot processing process of large-scale forging production, firstly, a steel ingot at room temperature is put into a heating furnace and heated to the temperature of 1200-1250 ℃, then the steel ingot is lifted out of the heating furnace and sent to a quick forging press to be forged and pressed into a forging, then the steel ingot is lifted into a sand pit or a post-forging heat treatment furnace from the quick forging press to be cooled, and finally the forging is lifted out of the sand pit or the heat treatment furnace to be subjected to surface quality inspection and marking and warehousing. The method is characterized in that the steel ingot raw material and the forged piece are produced, the lifting operation of a crane cannot be carried out in each process, and tools used for lifting the steel ingot or the forged piece need to meet the weight of a workpiece firstly and also need to consider the temperature of the workpiece, so that the forged piece can only be lifted by a chain or a lifting clamp in the production process, and the steel wire rope is strictly forbidden to be used for lifting the workpiece.
The lifting operation of the workpiece in the production process of the large forging piece is an important work in the safety production. In the annual personal injury accidents in hot working large forging production enterprises, the lifting injury accident is the first place. Therefore, the human body injury accident needs to be solved and controlled by being picked up from a source, namely a lifting tool. In the production process of large forgings, double-hook four-grab hanging tongs are generally used for hoisting operation. When the double-hook four-grab hanging tongs are used, the travelling crane needs to require the main hook and the auxiliary hook to be used. Therefore, a great deal of trouble and difficulty are brought to the quick forging press when producing large forgings, one person must start the crane, another person is needed to assist in operation, time and labor are wasted, and certain potential safety hazards exist.
In order to solve the hoisting problem of the large forging in the production process and ensure the normal operation of production and workpiece transportation, a hoisting tool must be designed to meet the normal hoisting transportation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a nipper is used in forging shop.
The utility model discloses an innovation point lies in the utility model discloses a simple and easy four claw pincers of single hook has guaranteed the security of lifting by crane the in-process, has reduced operating personnel's intensity of labour, has practiced thrift the time of frequently changing the instrument of lifting by crane.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the grasping forceps for the forging workshop comprise a pin shaft, wherein more than two groups of grasping forceps assemblies are arranged on the pin shaft, each grasping forceps assembly comprises two connecting rods and two forceps, hinge points are arranged on the two forceps, the forceps are divided into two sections as connecting sections and one end as grasping sections by taking the hinge points as separation points, one ends of the two connecting rods are hinged to the pin shaft, the other ends of the two connecting rods are hinged to the end parts of the connecting sections of the two forceps respectively, the two forceps are hinged at the hinge points, the two connecting rods and the connecting sections of the two forceps form a rhombus, and the two grasping sections form a C-shaped structure after the two forceps are hinged; and an inverted U-shaped hook is arranged on the pin shaft.
Further, the pin shaft is connected with the opening end of the inverted U-shaped hook.
Furthermore, the grabbing sections of the pliers, which are positioned on the same side, of each group of grabbing jaw assemblies are connected through a steel block. The steel block makes the connection between two sets of nipper assemblies firmer, and the security is higher.
Further, the grasping components are two groups. And the cost performance is highest under the condition of meeting the requirements of stability and safety.
The utility model has the advantages that:
1. the utility model designs a simple and easy four claw pincers of single hook have guaranteed the security of lifting by crane the in-process, have reduced operating personnel's intensity of labour, have practiced thrift the time of frequently changing the instrument of lifting by crane.
2. The utility model discloses be equipped with the steel block between the pliers of two sets of nipper subassemblies and connect, make the monolithic connection more firm, more stable when lifting by crane, the security is higher.
3. The utility model discloses simple structure for the expense of lifting by crane instrument is low, has practiced thrift the cost.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
Example 1: the grasping forceps for the forging workshop comprise a pin shaft 1, more than two groups of grasping forceps assemblies 2 are arranged on the pin shaft 1, the grasping forceps assemblies 2 are preferably two groups, each grasping forceps assembly 2 comprises two connecting rods 3 and two forceps 4, hinge points 5 are arranged on the two forceps 4, each forceps 4 is divided into two sections by taking the hinge points 5 as separation points, one section is a connecting section 4.1, one end is a grasping section 4.2, the grasping section 4.2 of each group of grasping forceps 4 positioned on the same side is connected through a steel block 6, one end of each connecting rod 3 is hinged to the pin shaft 1, the other end of each connecting rod 3 is hinged to the end of the connecting section 4.1 of each forceps 4, the two forceps 4 are hinged at the hinge points 5, each connecting rod 3 and the connecting section 4.1 of the two forceps 4 form a diamond shape, and the two grasping sections 4.2 form a C-shaped structure after the two forceps 4 are hinged; the pin shaft 1 is provided with an inverted U-shaped hook 7, and the pin shaft 1 is connected with the open end of the inverted U-shaped hook 7.
When the crane is lifted, the inverted U-shaped hook 7 is pulled upwards by the crane to drive the connecting sections 4.1 of the two connecting rods 3 and the two pliers 4 to be tightened inwards, so that the two grabbing sections 4.2 are driven to be close to one end far away from the connecting section 4.1, and the large forging piece is tightly grabbed to move upwards together.
The described embodiments are only some, but not all embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
