Description

Technical Field

[0001] The invention belongs to the technical field of mechanical assembly equipment, and in particular relates to a special installation device for a stuffing box of a reciprocating compressor. Background Art

[0002] A reciprocating compressor is a volumetric compression device that achieves gas pressurization and delivery by periodically changing the cylinder volume through the reciprocating motion of the piston on the cylinder. The stuffing box of a reciprocating compressor is used to seal the gas to prevent leakage from the gas piston rod, and a flange is provided at its outer end. Since the stuffing box is a wearing part, it needs to be disassembled and installed once it is damaged during use.

[0003] The commonly used method for replacing the stuffing box on a reciprocating compressor is as follows: insert the sling on the overhead crane into the center hole of the stuffing box, use the overhead crane and manual labor to lift the stuffing box from the mounting hole on one side of the cylinder body into the middle cylinder body, then insert a steel pipe into the center hole of the stuffing box, and 5-6 maintenance personnel standing on the outside of the mounting holes on both sides of the cylinder body will slowly lift the steel pipe together with the stuffing box, rotate it 90 degrees and slide it into the installation position, and finally tighten the bolts on the stuffing box flange to complete the installation process; the disassembly process is the opposite.

[0004] However, due to the large size and weight of the stuffing box of the reciprocating compressor, which is as high as about 160KG, and the narrow installation holes and installation positions on the side of the cylinder body, maintenance personnel and overhead cranes cannot perform well, so maintenance and disassembly are extremely difficult; in addition, it is easy to cause work-related accidents, low work efficiency, and a large number of staff. Summary of the invention

[0005] In order to solve the above problems, an object of the present invention is to provide a special installation device for a stuffing box of a reciprocating compressor.

[0006] In order to achieve the above-mentioned purpose, the special installation device for the stuffing box of a reciprocating compressor provided by the present invention includes a lifting ear, a cross bar, a support rod, a connecting rod, an E-shaped hinge, a fixing plate, a stuffing box rod and a lifting ear fixing rod; wherein the cross bar and the connecting rod are arranged in parallel; the upper and lower ends of the support rod are respectively connected to the same end of the cross bar and the connecting rod; the lifting ear fixing rod is arranged horizontally, one end is connected to the other end of the cross bar in a manner perpendicular to the cross bar, and the lifting ear is installed on the top surface; the other end of the connecting rod is connected to the E-shaped hinge; the stuffing box rod is arranged horizontally, and the inner end is connected to the outer end of the E-shaped hinge; the fixing plate is arranged vertically, the lower end is fixed to the outer end of the E-shaped hinge, and a flange fixing hole is formed on the upper part, and is perpendicular to the axis of the stuffing box rod, so that the fixing plate and the stuffing box rod can rotate 180 degrees in the horizontal plane.

[0007] The special installation device for the stuffing box of the reciprocating compressor also includes a handle installed at the lower part of the outer end surface of the support rod.

[0008] The special installation device for the stuffing box of the reciprocating compressor also includes oblique reinforcing ribs connected at the connection points between the support rod and the cross rod, the support rod and the connecting rod, and the cross rod and the lifting eye fixing rod.

[0009] The flange fixing hole is an elongated hole.

[0010] The special installation device for the stuffing box of a reciprocating compressor provided by the present invention has the following beneficial effects: labor-saving operation, accurate installation, and effective protection of other parts of the compressor. The number of installation personnel is reduced from 6 to 2, the operation is changed from manual handling to crane installation, and the disassembly and assembly time is shortened from 3 hours to 0.5 hours. It has been proved by multiple actual inspections that the efficiency can be increased by 90%, and the occurrence of industrial accidents is avoided to a large extent. BRIEF DESCRIPTION OF THE DRAWINGS
