Description

Special lifting tool for tamping hammer Technical Field The utility model relates to the field of special equipment for tamping coke oven mechanical equipment, in particular to a special lifting tool for a tamping hammer. Background The tamping hammer is one of key important components of the tamping machine, and mainly consists of a friction plate, a hammer rod and a hammer head. The hammer rod and the hammer head are of a welding structure, the welding assembly is called a 'tamping hammer rod' in the industry, and the friction plate is adhered to the tamping hammer rod through a glue curing agent. In all side-mounted stamp-charged ovens, a stamp-hammer is required. The lengths and other dimensions of the tamping hammers are also different according to the sizes of coal cakes set by various metallurgical coke ovens, and generally, the lengths of the individual tamping hammers are generally different from 8.5 to 11.5 meters and the weights are different from 400 kg to 500kg according to the current running tamping coke ovens. The tamping hammer belongs to a slender workpiece, the overall straightness requirement is high, the design requirement is +/-2mm, and in the processes of tamping hammer rod welding, friction plate bonding, tamping hammer transferring, installing and the like, a crane is needed to lift the tamping hammer and then send the tamping hammer to a designated working position. However, due to the longer length, some existing slings or slings are easy to bear uneven stress in the length direction of the tamping hammer rod during hoisting, stress is generated, hoisting instability is caused, or faults caused by bending deformation of the hammer rod occur, and when the bending deformation amount of the hammer rod exceeds 2mm, the tamping hammer can be scrapped. After-sales data are fed back, the stamping bending deformation is large, and the friction plate can also fall off, so that the stamping hammer is invalid. In order to effectively solve the problem, it is necessary to design and provide a special lifting tool for the tamping hammer, so the application is provided. Disclosure of utility model In order to solve the problems, the utility model provides a special lifting tool for a tamping hammer. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The special lifting tool for the tamping hammer comprises a lifting chain, the tamping hammer and a lifting tool and is characterized in that the lifting tool comprises a lifting arm, at least two groups of clamping assemblies are arranged at the bottom of the lifting arm, each clamping assembly comprises a fixing structure and two groups of rotating structures, each fixing structure comprises a mounting plate, two lug plate groups are welded at the bottoms of two sides of each mounting plate and are connected with each other in a welded mode, each lug plate group comprises two lug plates which are downward and parallel to each other, the upper portion of each mounting plate is welded with the bottom of the lifting arm, a hinge hole and a locking hole are formed in each lug plate, each rotating structure comprises a rotating plate and a clamping bottom plate, and the hinge hole and the locking hole are formed in each rotating plate. Preferably, the suspension arms are distributed along the horizontal direction, two lifting lugs which are symmetrical to each other are welded on the suspension arms, and the lifting lugs are connected with the suspension chain. Preferably, the rotating plate is inserted upwards into the middle position of the two mutually parallel lug plates, and the hinge holes and the locking holes on the rotating plate and the two lug plates are mutually matched. Preferably, an anti-slip side plate is arranged on one side of the rotating plate, and an anti-slip bottom plate is arranged on the clamping bottom plate. Preferably, the height dimension X of the anti-skid side plate is more than or equal to the height of the tamping hammer. Preferably, the distance X between the two side anti-slip side plates is =the width dimension of the tamping hammer +3mm The utility model has the following beneficial effects: This special hoist frock of tamping hammer can effectively prevent the in-process tamping hammer atress of hoist and mount tamping hammer uneven, and take place hoist and mount unstability or the condition of bending deformation, can be applicable to the hoist and mount work of the tamping hammer of different specification sizes through setting up fixed knot structure and two sets of revolution mechanic, through setting up skid-proof side board and skid-proof bottom plate, effectively avoided the skidding or the damage of bumping of tamping hammer hoist and mount in-process, guaranteed operation security and product's integrality.
