Description

Technical Field

[0001] This utility model belongs to the field of compressor repair technology, and in particular relates to a safety lock traction device for repairing reciprocating compressor pistons. Background Technology

[0002] Common failures of the piston body, a crucial component of a reciprocating compressor, include: piston ring breakage; piston ring seizure, loss of elasticity, and inability to expand; and excessive piston ring wear, leading to increased clearance. The main manifestations of piston rings failing to provide a seal are: increased exhaust temperature in that stage; decreased exhaust pressure in that stage; and reduced compressor discharge volume.

[0003] Piston inspection and maintenance of reciprocating compressors is a common maintenance task. The disassembly and assembly of piston components requires the cooperation of multiple people. Relying on a single tool such as a wooden pry bar is time-consuming, labor-intensive, inefficient, and cannot guarantee quality. Summary of the Invention

[0004] The purpose of this invention is to provide a safety lock traction device for the maintenance of reciprocating compressor pistons, which saves 2 / 3 of the maintenance time compared to the past, and achieves the goal of completing the inspection and maintenance work safely, efficiently and with high quality.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The present invention relates to a reciprocating compressor piston maintenance safety lock traction device, characterized in that it includes a double traction fixed support frame, a traction positioning bearing beam perpendicularly connected to the double traction fixed support frame, a spiral transmission rod disposed at the center of the traction positioning bearing beam and threadedly connected to the traction positioning bearing beam, a traction handle connected to the tail end of the spiral transmission rod, a bearing booster connected to the top end of the spiral transmission rod, and a piston connection lock connected to the bearing booster via a connecting rod.

[0007] The traction positioning bearing beam is equipped with two portable actuation handles.

[0008] A traction rod center pull sleeve is provided between the traction positioning bearing beam and the screw drive rod.

[0009] The dual traction fixed support frame is connected to the traction positioning bearing beam via support arm adjusting bolts.

[0010] Advantages of this utility model:

[0011] This utility model relates to a reciprocating compressor piston repair safety lock traction device. In the repair of the K1202 compressor of the combined unit, a safe and precise piston body repair traction device is used. The bracket is fixed according to the corresponding position, and the piston body is pulled out from the cylinder by turning the handle. The operator can then replace the faulty part. The whole repair process is very smooth, and the piston body can be extracted and installed in 45 minutes. The operation is simple, safe and reliable.

[0012] The compressor piston body maintenance traction equipment is easy and quick to assemble, has a wide range of applications, and is highly applicable. It can be used for the extraction and installation of piston bodies in horizontal, symmetrical balanced, and opposed compressors of the same type. It is easy to operate, practical, and can save 2 / 3 of the maintenance time compared to the past, saving time and effort, improving maintenance quality and efficiency, and achieving the goal of refined equipment maintenance.

[0014] The specific embodiments of this utility model are further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, this utility model discloses a reciprocating compressor piston maintenance safety lock traction device, characterized by including a double traction fixed support frame 4, a traction positioning bearing beam 5 vertically connected to the double traction fixed support frame 4, a spiral transmission rod 7 set at the center of the traction positioning bearing beam 5 and threadedly connected to the traction positioning bearing beam 5, a traction handle 9 connected to the tail end of the spiral transmission rod 7, a bearing booster 3 connected to the top end of the spiral transmission rod 7, and a piston connection lock 1 connected to the bearing booster 3 via a connecting rod 2.

[0016] The traction positioning bearing beam 5 is equipped with two portable actuation handles 6.

[0017] A traction rod center pull sleeve 8 is provided between the traction positioning bearing beam 5 and the screw drive rod 7.

[0018] The dual traction fixed support frame 4 and the traction positioning bearing beam 5 are connected by the support arm adjusting bolt 10.

[0019] Implementation method:

[0020] When preparing to remove the piston during compressor maintenance, first secure the double traction fixed support arm 4 to the cylinder body using bolts. Install the traction positioning bearing beam 5. Rotate the traction handle 9 counterclockwise to retract the screw drive rod 7. Install the connecting rod 2 onto the bearing booster 3. Install the piston connection lock 1 on the front section of the connecting rod 2. Rotate the traction handle 9 clockwise to advance the screw drive rod 7 until the piston connection lock 1 is close to the center of the piston. Lock the piston connection lock 1 to the piston. Rotate counterclockwise to slowly pull the piston out and place it on the ground for maintenance. The operation is complete. Piston maintenance traction utilizes the principle of threaded transmission as a piston body maintenance traction device for piston body extraction or installation. It is simple, quick, easy to operate, and the threaded transmission saves time and effort with high efficiency.
