The utility model provides a lifting device for stabilizing a piston rod, which aims to solve the problems that: how to improve the efficiency of the stabilization treatment of the piston rod. The key points of the utility model are as follows: the fixing plate, the iron chain and the bolts are welded in turn from top to bottom, and transverse pin holes are formed in the fixing plate; the welding of the iron chain and the bolt means that the lower end of the iron chain is welded on the bolt cap, and the bolt is matched with the connecting screw hole of the piston rod. Firstly, screwing a bolt into a connecting screw hole of a piston rod to be processed, so that the piston rod is installed on the piston rod; and the fixing plate is inserted into the groove-shaped furnace mouth of the pit furnace, and the transverse pin is inserted into the transverse pin hole of the fixing plate in a mode of transversely arranging the groove-shaped furnace mouth, so that the piston rod is hung in the pit furnace.
Description
Technical Field
The utility model relates to a lifting device for a piston rod of a reciprocating piston compressor, in particular to a lifting device used in stabilizing annealing treatment of the piston rod.
Background
The piston rod of the reciprocating piston compressor is in the shape of an elongated rod. In the machining process, the piston rod can generate larger machining stress and is easy to bend, so that the piston rod is required to be subjected to stabilizing treatment before finish machining, namely, the piston rod is vertically hung in a pit furnace and is subjected to annealing treatment, so that the stress is released, and the bending deformation of the piston rod is avoided. The current method for hanging the piston rod in the pit furnace is that a metal hoop is hooped at the shoulder of the piston rod near the upper part, then two left and right hanging iron wires are used for hanging the metal hoop and the piston rod thereof in the pit furnace, in particular, the lower ends of the left and right hanging iron wires are wound on the metal hoop, the upper ends of the two hanging iron wires extend into the groove-shaped furnace mouth at the upper end of the pit furnace and are wound on a transverse pin transverse to the groove-shaped furnace mouth, and at the moment, the piston rod is hung in the pit furnace in a vertical mode. The method has the defects that to ensure that the piston rod is hung in the furnace in a vertical (non-inclined) mode, not only is the metal hoop required to be kept in a horizontal state, but also the lower end winding points of two equal-length hanging iron wires are positioned on the same diameter line of the metal hoop, obviously, the installation is troublesome, the efficiency of stabilizing the piston rod is reduced, and particularly, the lifting device can deform after being repeatedly used, and meanwhile, the condition is met more difficultly; moreover, the hanging iron wires are stressed in a high-temperature environment for a long time and are easy to break, so that potential safety hazards are formed.
The center of the front end (i.e., piston end) of the piston rod of a reciprocating piston compressor is typically provided with an axial connecting screw hole for connecting to other equipment.
Disclosure of Invention
In order to solve the technical problems, the utility model aims to provide a lifting device for stabilizing a piston rod.
The purpose of the utility model is realized in the following way: it includes the horizontal round pin, characterized by: the fixing plate, the iron chain and the bolts are welded in turn from top to bottom, and transverse pin holes are formed in the fixing plate; the welding of the iron chain and the bolt means that the lower end of the iron chain is welded on the bolt cap, and the bolt is matched with the connecting screw hole of the piston rod.
The use method of the utility model is that firstly, the bolt is screwed into the connecting screw hole of the piston rod to be treated, so that the piston rod is arranged on the utility model; and the fixing plate is inserted into the groove-shaped furnace mouth of the pit furnace, and the transverse pin is inserted into the transverse pin hole of the fixing plate in a mode of transversely arranging the groove-shaped furnace mouth, so that the piston rod is hung in the pit furnace.
Compared with the prior art, the utility model has the following positive effects: because the iron chain belongs to flexible connection, the iron chain can effectively ensure that the iron chain and the piston rod always maintain a vertical hanging state under the action of gravity. And secondly, the installation is simple and convenient, and the efficiency is improved.
Drawings
The utility model is further described below with reference to the drawings.
FIG. 1 is a schematic view of the hanging piston rod of the present utility model in a pit furnace.
Fig. 2 is a left side view of fig. 1.
Description of the embodiments
The fixing plate 1, the iron chain 4 and the hanging bolt 5 are welded in turn from top to bottom, and a transverse pin hole 11 is arranged on the fixing plate; the chain links at the upper and lower ends of the iron chain are open-type chain links, specifically the upper head chain link 42 is U-shaped, and the lower head chain link 41 is inverted U-shaped; the bolt cap 52 is in the shape of a straight quadrangular prism, a hexagonal prism or a cylinder. The welding of the fixing plate 1 and the iron chain 4 means that the lower end of the fixing plate is inserted into the U-shaped inner side of the upper head chain link from the upper side downwards, so that the thickness surfaces of the two sides of the fixing plate are contacted with the upper head chain link and welded; the iron chain and bolt welding means that the bolt cap 52 is inserted into the reverse U-shaped inner side of the lower head link 41 from the lower side upward, and the bolt cap is brought into contact with the lower head link and welded. Therefore, the contact area between the fixing plate and the iron chain as well as between the iron chain and the bolt cap can be increased, and the welding fastness is further improved. The bolt is matched with the connecting screw hole of the piston rod.
The use method of the utility model is that firstly, the bolt 5 is screwed into the connecting screw hole of the piston rod 6 to be processed, so that the piston rod is installed on the utility model; after the fixing plate is stretched into the groove-shaped furnace mouth 3 of the pit furnace, the transverse pin 2 is inserted into the transverse pin hole 11 of the fixing plate in a mode of transverse to the groove-shaped furnace mouth, so that the piston rod 6 is hung in the pit furnace.
