A quick-release blind plate auxiliary installation device for ball receiving and launching tubes

Abstract

This utility model relates to the field of pigging equipment, specifically to an auxiliary installation device for a quick-release blind flange on a pig launching / receiving tube. It includes a support base with several pull claws arranged around it. The support base also has mounting screw holes, each fitted with a push screw. By using a support base with multiple pull claws, the pull claws hook onto the outer wall of the pig launching / receiving tube during the push screw's movement of the blind flange, providing tension to the support base. This allows the push screw to move the blind flange into the tube, achieving the pushing operation of the blind flange. With the limiting effect of the mounting screw holes, the push screw can advance slowly and smoothly, making operation simpler and less strenuous. Furthermore, no sparks are generated during the pushing process, reducing the safety risks associated with the blind flange pushing operation.

Description

Technical Field

[0001] This utility model relates to the field of pigging equipment, and in particular to an auxiliary installation device for quick-opening blind flanges on pig launching and receiving tubes. Background Technology

[0002] Natural gas gathering and transmission stations are equipped with launching and receiving tube devices to remove accumulated liquid in pipelines and improve the efficiency of natural gas transmission. The launching and receiving tube devices are fitted with locking ring-type quick-opening blind flanges. To open the blind flange, the safety interlock mechanism is removed by unscrewing the safety bolts. The switch handle is inserted into the handle seat hole, and the handle is turned counterclockwise to retract the locking ring. The switch handle is then inserted into the switch handle hole, and continuous, even force is applied to open the blind flange cover. To close, the switch handle is inserted into the switch handle hole, and the handle is pushed to close the blind flange cover. The blind flange cover is then held in place by hand, the switch handle is inserted into the handle seat, and turned clockwise to expand the locking ring, locking the blind flange cover. The safety interlock mechanism is then installed, and the safety bolts are slowly tightened.

[0003] When closing the blind flange on site, due to its excessive weight and the elasticity of the sealing ring installed inside, it is difficult for operators to push the blind flange to the intended position by hand alone. When the locking ring cannot be fully inserted into the locking ring groove, operators can only use tools such as pry bars and hammers to strike the locking ring and force it into the groove under external force. Over time, this will cause the locking ring to gradually deform or even be damaged. Replacing the locking ring will increase production costs. At the same time, the striking method is prone to generating sparks, which can easily cause the residual natural gas in the pipeline to explode, posing a serious threat to the overall safety of the site.

[0004] Therefore, a technical solution is needed to address the issue that when the quick-opening blind flange of the launching and receiving tube is closed, tools such as pry bars and hammers are needed to strike the locking ring, which can easily damage the locking ring and generate sparks during the striking process, posing a safety hazard to the gas production station. Utility Model Content

[0005] The purpose of this utility model is to overcome the technical problem that in the prior art, when closing the quick-opening blind flange of the launching and receiving tube, it is necessary to use tools such as pry bars and hammers to strike the locking ring, which can easily lead to damage to the locking ring. At the same time, the striking process can easily generate sparks, posing a safety hazard to the gas production station. This utility model provides an auxiliary installation device for the quick-opening blind flange of the launching and receiving tube.

[0006] This utility model provides an auxiliary installation device for quick-opening blind plate of ball receiving and launching tube, including a support base, a plurality of pull claws are provided on the support base, the plurality of pull claws are arranged around the support base, the support base is provided with mounting screw holes, and the mounting screw holes are equipped with push screws.

[0007] This utility model discloses a quick-opening blind plate auxiliary installation device for a ball receiving and launching tube. In use, the end of the pull claw hooks onto the ball receiving and launching tube, and the push screw on the support base is rotated. After the push screw is pressed against the blind plate, the pull claw is tightened on the ball receiving and launching tube. Further rotation of the push screw causes the push screw to move to one side of the blind plate, thereby pushing the blind plate into the ball receiving and launching tube.

[0008] Preferably, the pull claw includes a claw bar and a connecting rod, one end of the connecting rod is hinged to the claw bar, and the other end is hinged to the support base, and a claw hook is provided at the end of the claw bar.

[0009] The pull claw is formed by the hinge of the claw rod and the connecting rod. It can rotate relative to each other during use, which makes it easier to install and remove on the ball receiving tube. It also allows the pull claw to adapt to ball receiving tubes of different sizes.

[0010] Preferably, the claw bar is provided with a hinge hole, and a mounting shaft is disposed in the hinge hole, and the connecting rod is connected to the mounting shaft.

[0011] A rotatable connection between the connecting rod and the claw rod was achieved.

[0012] Preferably, the number of hinge holes is at least two, and all the hinge holes are arranged along the length direction of the claw bar.

[0013] By installing connecting rods through different hinge holes, the length of the extended claw can be adjusted, thereby increasing the applicability of the claw and adapting it to different sizes of ball launcher and receiver tubes.

[0014] Preferably, the claw bar is provided with claw hooks at both ends, and the two claw hooks are respectively positioned facing the two sides of the claw bar.

[0015] This allows both ends of the claw to be used to hook objects. If the claw hook at one end of the claw is damaged, the claw can be rotated 180° to install a new, intact claw hook, thus extending the service life of the claw. At the same time, claw hooks of different shapes can be set at both ends of the claw to adapt to different structures or components.

[0016] Preferably, the claw bar is provided with a light-reducing groove, which is provided along the length direction of the claw bar.

[0017] By incorporating a weight-reducing groove while ensuring the strength of the claw, the weight of the claw can be significantly reduced, making the device easier to use.

[0018] Preferably, the number of pull claws is three, and the three pull claws are evenly arranged around the support base.

[0019] The three pull claws provide a more stable tension to the support seat for installing the push screw during the process of the push screw pushing the blind plate, reducing the risk of the pull claws becoming loose.

[0020] Preferably, the device further includes several fixing seats, which are used to be mounted on the outer wall of the ball receiving and launching tube, and the pull claw is connected to each fixing seat in a one-to-one correspondence.

[0021] By adding a fixing seat to the outer wall of the receiving and launching tube, it is easier for the pull claw to exert force, and at the same time, it avoids the problem of the pull claw directly hooking onto the main structure of the receiving and launching tube, causing damage to the main structure of the receiving and launching tube.

[0022] Preferably, it further includes a pad, which is used to be disposed on the outer end face of the blind plate, and the push screw abuts against the pad.

[0023] A shim is added between the push screw and the blind plate. The push screw acts on the shim, indirectly driving the blind plate to move, thus avoiding damage to the blind plate during the pushing process.

[0024] Preferably, the pad is provided with a limiting groove, and the end of the abutting screw is embedded in the limiting groove.

[0025] During the pushing process, the pushing screw can be embedded in the limiting groove of the pad, which can reduce the risk of the pad slipping.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. The present invention provides an auxiliary installation device for quick-opening blind plate of receiving and launching tube. By setting a support base with multiple claws, the claws hook onto the outer wall of the receiving and launching tube during the process of pushing the blind plate by the push screw, thereby providing a pulling force to the support base, so that the push screw can push the blind plate into the receiving and launching tube, realizing the pushing operation of the blind plate;

[0028] 2. The present invention provides a quick-opening blind flange auxiliary installation device for a ball receiving and launching tube. The push screw for pushing the blind flange is threadedly connected to the support seat. Under the limiting action of the installation screw hole, the push screw can advance slowly and smoothly, making the operation simpler and more labor-saving. No sparks will be generated during the pushing of the blind flange, reducing the safety risk of blind flange pushing operation. Attached Figure Description
