[0002] Due to various problems occurring during the operation of the compressor, maintenance is required. During the maintenance work, the equipment and system need to be disassembled or opened. When the working source in the equipment and system may endanger the safety of personnel and equipment, it is necessary to ensure that the working energy in the access area can be isolated, so as to be completely, reliably and reasonably cut off, so as to ensure that the operation of the equipment will not endanger the safety of the staff, and the work of the staff will not affect the normal operation of the equipment.
[0003] Currently, the most common method is to isolate the unit from the outside world. The commonly used method in the market is blind plate isolation. When these blind plates are needed, a suitable blind plate needs to be found. On the one hand, it takes time and effort. On the other hand, due to the different sizes of the pipelines to be installed, the required blind plate sizes are also different. Some blind plates are too large and thus heavy. During the installation process of the blind plate, operational errors are likely to cause personal injuries, and hoisting equipment is also required for assistance, etc., which prolongs the maintenance time.
[0004] In summary, how to provide a blind plate structure with a non-dismantling method to shorten the maintenance time is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model
[0005] In view of this, the purpose of the utility model is to provide a blind plate structure, which adopts a non-dismantling method and structure to reduce the safety hazards during the blind plate switching process and improve the switching efficiency.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0011] A rotating member is provided on the rotating column. The rotating member has an annular structure and is installed in the through hole and coaxially arranged with the through hole. The rotating member is used to reduce the frictional force when the connecting portion rotates.
[0012] Further, the rotating member can slide along the axial direction of the rotating column on the rotating column.
[0013] Further, the rotating member adopts a ball bearing.
[0014] Further, a limiting mechanism is also included. The limiting mechanism is used to limit the rotation of the connecting portion around the axis of the rotating column.
[0015] Further, the limiting mechanism includes:
[0016] At least one fixing plate, which is installed on the rotating column and slides along the axial direction of the rotating column;
[0017] When the fixing plate contacts the connecting portion, the fixing of the connecting portion is achieved.
[0018] Further, the fixing plate adopts an L-shaped structure. The fixing plate is threadedly connected to the rotating column, and the rotating column is rotatably installed in the pipeline.
[0019] Further, the limiting mechanism includes:
[0020] A fixing plate, fixedly installed on the rotating column;

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] The core of the present utility model is to provide a blind plate structure, which adopts a non-detachable method and structure to reduce the safety hazards during the blind plate switching process and improve the switching efficiency.
[0031] Please refer to Figure 1 - Figure 2 , a blind plate structure, including a solid blind plate 1 and a hollow blind plate 2. The solid blind plate 1 and the hollow blind plate 2 are connected by a connecting part 3. A through hole 4 is provided on the connecting part 3. A rotating column 6 is installed on the pipeline. The through hole 4 of the connecting part 3 passes through the rotating column 6 and can drive the solid blind plate 1 and the hollow blind plate 2 to rotate along the axis of the rotating column 6.
[0032] Optionally, in order to facilitate the installation of the rotating column 6 on the pipeline, in some embodiments, a fixing plate 7 or a fixing protrusion can be installed at the pipeline flange position to facilitate the installation of the rotating column 6 on the pipeline.
[0033] Optionally, in some embodiments, the rotating column 6 can be installed on the pipeline in a fixed manner, such as welding fixation, or screwed and fixed on the pipeline by threads.
[0034] In other embodiments, the rotating column 6 can be installed on the pipeline in a rotating manner. For example, a slot hole is provided on the fixing plate 7, and a bearing is installed in the slot hole. The rotating column 6 is fixedly connected to the inner ring of the bearing, thus achieving the purpose that the rotating column 6 can rotate automatically.
[0035] Optionally, in order to further improve the accuracy of the blind plate position after rotation, in some embodiments, the axes of the through hole 4, the solid blind plate 1 and the hollow blind plate 2 are located in the same plane to improve the accuracy of the blind plate position after rotation.
[0036] During use, first move this blind plate structure to the pipeline where it needs to be installed, and install a mounting plate or a mounting protrusion on the pipeline, etc., to facilitate the installation of the rotating column 6 on the pipeline. The solid blind plate 1 and the hollow blind plate 2 are connected by the connecting part 3. The connecting part 3 enables the solid blind plate 1 and the hollow blind plate 2 to rotate along the axis of the rotating column 6, thereby realizing rapid switching. At the same time, it can avoid the problem of blind plate position deviation caused by using the flange mounting hole as the rotation axis. When equipment maintenance and repair are required, only need to rotate the blind plate to connect with the pipeline flange, then the pipeline can be effectively cut off, thus ensuring the safety during maintenance and repair, and it is more conducive to the use of larger-size and heavier blind plates. On the one hand, it avoids the need to find a suitable-size blind plate for installation every time during maintenance and repair, improving the convenience of blind plate replacement. On the other hand, it avoids the need for auxiliary lifting equipment, greatly shortening the maintenance and repair duration and reducing the cost.
[0037] In order to further improve the smoothness of the connecting portion 3 during rotation, in some embodiments, a rotating member 5 is provided on the rotating column 6. The rotating member 5 is of an annular structure. The rotating member 5 is installed in the through-hole 4 and is coaxially arranged with the light-transmitting hole. The rotating member 5 is used to reduce the frictional force of the connecting portion 3 during rotation. That is to say, through the rotating member 5, the frictional force during rotation between the connecting portion 3 and the rotating column 6 is reduced, which is beneficial to more labor-saving switching when using a heavy blind plate.
[0038] Optionally, in some embodiments, the rotating member 5 can adopt a bearing, that is, the outer ring of the bearing is fixed to the through-hole 4, and the inner ring of the bearing contacts the rotating column 6, and ball bearings, roller bearings, etc. can be selected.
[0039] When the above structure is adopted, in order to further facilitate the movement of the blind plate along the axis direction of the rotating column 6, a limiting groove is provided on the rotating column 6, and a limiting block that can freely slide inside the limiting groove is provided on the inner ring of the bearing, so as to facilitate the movement of the blind plate on the rotating shaft.
[0040] In some other embodiments, the shape of the rotating member 5 can be adjusted. For example, the rotating member 5 is annular, but the contact position between it and the rotating column 6 adopts a circular arc shape with a cross-section opening away from the rotating column 6. Through the contact between the circular arc structure and the rotating column 6, the purpose of reducing the resistance is achieved by reducing the contact area.
[0041] In some other embodiments, the rotating member 5 can adopt a material with a lower coefficient of friction. For example, ceramic material, polytetrafluoroethylene or graphite and other materials can be selected.
[0042] In some other embodiments, a plurality of strip-shaped grooves are provided on the rotating column 6 along its axis direction. The plurality of strip-shaped grooves are circumferentially and arrayedly distributed along the axis of the rotating column 6, and a roller is rotatably installed inside the strip-shaped groove. The outer surface of the roller extends out of the strip-shaped groove. At this time, the through-hole 4 on the connecting portion 3 passes through the rotating column 6, and the supporting and rotating effects of the connecting portion 3 are realized under the action of a plurality of rollers, reducing the damping of the rotation of the connecting portion 3, and enabling the connecting portion 3 to slide along the axis direction of the rotating column 6, so as to facilitate the adjustment of the position of the blind plate.
[0043] Please refer to Figure 2 , in some embodiments, a limiting mechanism is further included. The limiting mechanism is used to limit the rotation of the connecting portion 3 around the axis of the rotating column 6. Specifically, the position of the blind plate is limited through the limiting mechanism to avoid the situation of misrotation during maintenance, replacement or use, so as to improve its safety during use.
[0044] Optionally, the limiting mechanism includes at least one fixing plate 7, which is installed on the rotating column 6 and slides along the axis direction of the rotating column 6. When the fixing plate 7 contacts the connecting portion 3, the fixing of the connecting portion 3 is achieved. Specifically, a limiting groove is provided on the rotating column 6, which is used to limit the sliding of the fixing plate 7 along the axis direction of the rotating column 6 as much as possible. Therefore, when the fixing plate 7 moves between the two blind plates, the position of the blind plates can be restricted, avoiding the situation of incorrect rotation.
[0045] Optionally, in order to further improve the fixing effect of the fixing plate 7 during use, in some embodiments, the fixing plate 7 adopts an L-shaped structure. By adopting the L-shaped structure, the locking effect on the blind plates can be further improved, avoiding the situation that the blind plates are separated from the fixing plate 7 during the process of limiting the blind plates.
[0046] In addition, in some embodiments, the fixing plate 7 is threadedly connected to the rotating column 6, and the rotating column 6 is rotatably installed on the pipeline. That is to say, when it is necessary to adjust the position of the fixing plate 7, only the rotating column 6 needs to be rotated. Through the threaded cooperation between the rotating column 6 and the fixing plate 7, the movement of the fixing plate 7 is realized, and under the action of thread self-locking, the fixing stability of the fixing plate 7 is further improved.
[0047] In other embodiments, a cylinder can be provided on the rotating column 6, and the position of the fixing plate 7 is adjusted by driving the cylinder, so as to achieve the fixing function of the fixing plate 7.
[0048] In other embodiments, the limiting mechanism includes a fixing plate 7 fixedly installed on the rotating column 6 and a limiting rod. The limiting rod is slidably installed on the fixing plate 7 and is arranged parallel to the axis of the rotating column 6. A limiting hole is provided on the connecting portion 3. When the limiting rod is inserted into the limiting hole, the limiting of the connecting portion 3 is realized. That is to say, by adopting a limiting rod arranged parallel to the axis of the rotating column 6, when it is necessary to limit the position of the blind plates, only the limiting rod needs to be slid and passed through the limiting hole on the connecting portion 3, and the positions of the two blind plates can be fixed, which is more convenient and fast, and at the same time, the limiting effect is more firm.
[0049] Optionally, in order to further increase the angle range when limiting the blind plates, in some embodiments, several limiting holes can be provided and arranged along the axis direction of the rotating column 6, so that the angle range during limiting can be increased.
[0050] Optionally, in order to further improve the stability when limiting the blind plates, in some embodiments, an elastic member can be provided on the rotating column 6 to drive the limiting rod to move towards the connecting portion 3. Therefore, after the limiting rod is inserted into the limiting hole, the stability of the limiting rod can be ensured under the action of the elastic member. The elastic member can adopt elastic structures such as springs and rubber ropes.
[0051] That is to say, the key point of the present utility model lies in that: by means of the connecting part 3, the solid blind plate 1 and the hollow blind plate 2 can rotate along the axis of the rotating column 6, so as to achieve rapid switching. At the same time, it can avoid the problem of blind plate position deviation existing in using the flange mounting hole as the rotation axis. When equipment maintenance and repair are required, only need to rotate the blind plate to connect with the flange of the pipeline, then the pipeline can be effectively cut off, thus ensuring the safety during maintenance and repair, and it is more conducive to the use of blind plates with larger size and weight. On the one hand, it avoids the need to find a blind plate with a suitable size for installation every time during maintenance and repair, improving the convenience of blind plate replacement. On the other hand, it avoids the need for the assistance of lifting equipment, greatly shortening the duration of maintenance and repair and reducing the cost.
[0052] The various embodiments in this specification are described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same and similar parts among the various embodiments, reference can be made to each other.
[0053] The above has introduced in detail a blind plate structure provided by the present utility model. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
