Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tailpipe hanger assembly platform. Background Technology

[0002] The tailpipe hanger is a key piece of equipment in the oil drilling and completion process. Its function is to seal and suspend the tee section between the drilled casing and the upper casing. The tailpipe hanger has a complex structure, usually assembled from multiple precision components such as hydraulic cylinders, slips, sealing components, and upper connectors. The assembly requires high precision and the assembly process is cumbersome.

[0003] Currently, the assembly of tailpipe hangers largely relies on manual operation and coordination among multiple dispersed workstations, which presents the following problems:

[0004] Low assembly efficiency: Due to the complex assembly sequence of each component, multiple hoisting, positioning and fastening are required. The manual operation is slow and it is difficult to achieve continuous and assembly line operation.

[0005] Unstable assembly quality: Manual assembly is easily affected by the operator's experience and condition, especially in key processes such as aligning the hydraulic cylinder with the body guide groove and pressing the sealing components, which can easily lead to deviations, affecting sealing performance and service life.

[0006] Poor adaptability: Traditional assembly platforms are difficult to adapt to the co-line assembly of various models of tailpipe hangers. When changing product models, tooling and process flow need to be readjusted, resulting in a long preparation cycle.

[0007] Poor ergonomics: Unreasonable operating height and repetitive movements can easily lead to operator fatigue, affecting work safety and assembly consistency.

[0008] Therefore, there is a lack of an integrated assembly platform for tailpipe hangers that can achieve multi-model compatibility, high degree of automation, stable assembly accuracy, and meet ergonomic requirements in the existing technology. Utility Model Content

[0009] The purpose of this invention is to provide a tailpipe suspension assembly platform to solve the problems mentioned in the background art.

[0013] A platform work area is provided on the front side of the transplanting track.

[0014] A transfer frame is provided on the front side of the servo electric cylinder and the mobile drilling machine.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] I. This utility model realizes automated pressing and tightening operations, enabling the one-time assembly of multiple models of tailpipe hangers on a single platform;

[0017] II. The assembly platform of this utility model is ergonomically designed to ensure that operators can work at a horizontal height of 1 to 1.1 meters. The platform enables the mechanized operation of three actions: workpiece clamping, auxiliary rotation, and part pressing into the assembly.

[0018] Third, this utility model satisfies the assembly of a series of tailpipe suspension units and the whole assembly, and reduces the assembly time of a single set by 30% while ensuring the assembly quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-2This utility model provides a technical solution: a tailpipe hanger assembly platform, including a robot gripper 3, a number of feeding worktables 1 are provided on one side of the robot gripper 3, a number of feeding trays 2 are provided on the feeding worktables 1, a transfer track 5 is fixedly provided on the rear side of the robot gripper 3, a number of clamping claws 12 are slidably installed on the transfer track 5 via a sliding plate, and a servo press 6 is fixedly installed at the top center of the transfer track 5.

[0024] A tailstock frame 10 is fixedly installed on the left side of the transplanting track 5. An assembly track 13 is installed on the front side of the tailstock frame 10. A servo electric cylinder 7, a mobile drilling machine 8, and an upper clamping machine 9 are installed on the assembly track 13 in sequence from left to right via sliders.

[0025] A partition 4 is fixedly installed on the outer side of the robot gripper 3.

[0026] A platform work area is set up on the front side of the transplanting track 5.

[0027] A transfer frame 11 is provided on the front side of the servo electric cylinder 7 and the mobile drilling machine 8.

[0028] The assembled units are transferred to the overall assembly platform, and the pre-assembled components are hoisted from the buffer platform to the overall assembly platform one by one.

[0029] The screws are fitted and pressed in manually using a mobile drilling machine 8, and the sealing box is pressed in using a servo electric cylinder 7.

[0030] The overall assembly is completed on the overall assembly platform, which is equipped with an automatic thread tightening device to pre-tighten the joint threads.

[0031] Tighten the threads. The assembly platform, which is at the same height as the upper tightening machine 9, transfers the pre-tightened threaded product to the adjacent upper tightening machine 9 to complete the final tightening of the threads.

[0032] The specific assembly process of the tailpipe suspension unit is as follows:

[0033] 101. Place the main body upside down on the platform and use a crane to place the main body into the manual operation station.

[0034] 102. Assemble the O-rings or Glyd rings on the main body at the manual station.

[0035] 103. Place each part on the loading workbench 1 and position it according to its positioning point. Operate the control panel to send the loading tray 2 into the working range of the robot gripper 3 (the loading tray 2 has a track at the bottom and is controlled by the panel).

[0036] 104. Assemble the liquid cylinder onto the main body. The robot places the liquid cylinder, which is positioned at the designated location on the loading tray 2, onto the main body. The rotation angle is controlled by the PLC program to align the guide hole of the liquid cylinder with the guide groove of the main body, and the cylinder is then placed at the end of the main body. Before the robot grasps the liquid cylinder, the camera measures the inner and outer diameters of the cylinder. Once the part is correctly identified, it is grasped.

[0037] 105. Automatically transfer the assembled unit to station 6 of the servo press. After the hydraulic cylinder of each station is loaded, the equipment automatically transports the main body and hydraulic cylinder of each station to station 6 of the servo press in sequence.

[0038] 106. The servo press 6 automatically presses the liquid cylinders in sequence. With the cooperation of the transfer rail 5, the servo press 6 automatically presses the liquid cylinders to the set position in sequence. According to the pre-determined program, the guide hole of the liquid cylinder and the guide groove of the body are automatically corrected and aligned to complete the pressing.

[0039] 107. Assemble the clapper assembly. The robot gripper 3 automatically picks up the clapper assembly from the feeding tray 2 and automatically inserts it into the predetermined position of the main body.

[0040] 108. Assemble the retaining ring and end ring. This process is done manually. After the loading tray 2 assembles the retaining ring assembly and the main body, the ground rail automatically moves to the platform working area. The manual person puts the end rings on the top of the main body one by one. After the operation is completed, click the white button on the platform button box. The transfer rail 5 automatically returns to the assembly position of the robot gripper 3 and continues the automated assembly operation.

[0041] 109. Assemble the upper connector. The robot gripper 3 automatically grabs the upper connector of the feeding tray 2 and fits it into the body. The threaded connection is completed by using the hydraulic chuck base pre-tightening device.

[0042] 110. Transfer the assembled unit to the overall assembly platform. The transfer track 5 moves the assembled product unit to the unloading platform. Operate the control panel to move the unloading platform to the vicinity of the overall assembly platform. (The unloading platform has a track at the bottom and is controlled by the panel).
