It includes two coaxially sliding end pipes, End Pipe 1 and End Pipe 2, which together constitute the compensator. An inner pipe extends coaxially to one side of the inner wall of End Pipe 1, and a bellows is coaxially fixed to one end of End Pipe 2.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of compensators, in particular to a hinge type compensator capable of absorbing thrust. BACKGROUND

[0002] The hinge type compensator is an elastic compensation device connecting the bellows and the end pipe through a hinge mechanism, mainly used for absorbing angular displacement or transverse displacement in the pipeline system. The core structure includes a bellows, a hinge plate, a pin shaft and a balance ring (part of the models contain a universal ring), which realizes displacement compensation through the rotation characteristics of the hinge, and converts the blind plate force (thrust) generated by the pressure in the pipeline into shear force and bending moment of the hinge rod, avoiding additional external force on the pipeline.

[0003] For the existing hinge type compensator, the inventor found the following defects:

[0004] When the pipeline is running, the medium flow impact and temperature change cause the bolt to repeatedly bear alternating loads, the friction between the threaded pairs decreases, and loosening is caused. For example, the hinge compensator of the power plant boiler powder conveying pipeline causes the nut to fall off due to vibration, causing stress concentration in the pipeline.

[0005] The traditional hinge type compensator is prone to thrust concentration, fatigue failure and loosening problems under high pressure and high temperature working conditions due to single structure, material performance limitations and bolt fastening defects, which seriously restricts the reliability of the equipment.

Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0034] The application provides a technical scheme of a hinge-type compensator capable of absorbing thrust: a hinge-type compensator capable of absorbing thrust, comprising:

[0035] The end tube one 1 and the end tube two 2 slide coaxially, the end tube one 1 and the end tube two 2 constitute the compensator, the inner wall of the end tube one 1 is coaxially connected with the inner tube 3 on one side, one end of the end tube two 2 is coaxially fixedly connected with the corrugated tube 4, the corrugated tube 4 surrounds the inner tube 3, the inner tube 3 slides with the inner wall of the end tube two 2, and the length of the inner tube 3 completely blocks and covers the connection between the end tube two 2 and the corrugated tube 4, two supporting members are symmetrically arranged at the outer walls of the end tube one 1 and the end tube two 2, and four absorbing members are uniformly arranged at the outer walls of the end tube one 1 and the end tube two 2 and staggered with the supporting members, and one limiting member is arranged at the upper end and the lower end of each absorbing member.

[0036] The limiting member is used for adaptively locking the connection between the absorbing member and the compensator, so as to avoid loosening of the connection of the equipment under vibration.

[0037] Further, the limiting member can be arranged according to actual needs, and it is not necessary to arrange one limiting member at the upper end and the lower end of each absorbing member, and the number of the limiting members can be regularly and evenly distributed around the compensator.

[0038] Reference Figures 1-5The end pipe one 1 and the end pipe two 2 are connected with the pipeline through flanges at two ends, when there is pressure and instantaneous impact force in the pipeline, the device can absorb the force through the cooperation of the absorbing member and the bellows 4, and can assist the device to reset under the action of the absorbing member.

[0039] The supporting member is used for supporting the compensator on both sides to improve the strength of the compensator.

[0040] The limiting member fixes the two ends of the absorbing member, and only supports the bolt to rotate in one direction (the tightening direction of the bolt), so as to avoid loosening of the bolts at the connection due to vibration of the compensator.

[0041] The absorbing member includes two reinforcing plates 11 fixedly connected to the upper and lower ends of the outer wall of the compensator respectively, and an active notch 12 is vertically formed in the middle of the outer end of each reinforcing plate 11, and a screw rod 13 is threadedly connected in the two active notches 12, and two nuts 14 are threadedly connected in sequence at the tail end of the screw rod 13, and the two nuts 14 are installed on the same side of the two reinforcing plates 11.

[0042] Referring to Figures 4-6 , the screw rod 13 passes through one of the active notches 12 and the tail end passes through the other active notch 12, and the nut 14 is screwed and installed with the head of the screw rod 13 supported by the reinforcing plate 11, which ensures the fixation of the head of the screw rod 13 and the connected reinforcing plate 11, and the tail end of the screw rod 13 is connected to the reinforcing plate 11 above the end pipe one 1 (the direction needs to refer to Figure 5 , which needs to be determined according to the actual installation situation), and the screw rod 13 is connected to the end pipe one 1 and the end pipe two 2, and the end pipe one 1 and the end pipe two 2 are synchronously slid inwardly under the connection of the top of the bellows 4 and the end pipe one 1, so that the compensator can adaptively slide under the thrust.

[0043] The outer wall of the screw rod 13 is slidably connected with the two active notches 12.

[0044] Referring to Figure 6 , when the screw rod 13 normally supports the compensator, it also adapts to the change of the non-radial force of the compensator, and ensures that the screw rod 13 can be returned to the original position under the limiting member, so as to realize the stable operation of the compensator.

[0045] A supporting spring 15 is wound around the outer wall of the screw rod 13, and the upper and lower ends of the supporting spring 15 are coaxially fixedly connected with a ring piece 16, and the outer ends of the two ring pieces 16 abut against the inner ends of the active notches 12.

[0046] Referring to Figures 4-6 , the supporting spring 15 and the ring piece 16 can provide absorption function to the axial force when the compensator is working, and provide additional supporting force to the end pipe one 1 and the end pipe two 2, and assist the bellows 4 to quickly return to the original position.

[0047] Further, since the size of the movable slot 12 is larger than the outer wall of the screw rod 13, and the sliding direction of the movable slot 12 is arranged along the radial direction of the compensator, when facing the radial force, the screw rod 13 matched and sliding in the movable slot 12 can also provide support, effectively absorbing the thrust.

[0048] One limiting piece includes a connecting plate 17 fixedly installed at the outer side of the reinforcing plate 11, the outer end of the connecting plate 17 is fixedly connected with a C-shaped and outwardly open arc-shaped movable block 30, the outer side of the two ends of the arc-shaped movable block 30 is symmetrically provided with two radial sliding grooves 21 parallel along the side edge of the connecting plate 17, the two radial sliding grooves 21 are both slidingly connected with a sliding rod 22, the top end of the two sliding rods 22 is both fixedly connected with an arc-shaped block 19, the inner side of the two ends of the two arc-shaped blocks 19 is both fixedly connected with a vertical sliding frame 20, and the other side of the middle part of the arc-shaped block 19 is connected with a reset spring 18 at the inner end of the connecting plate 17.

[0049] Referring to Figure 6 and Figure 7 , the elastic potential energy of the reset spring 18 stably pushes the entire arc-shaped block 19 to move outward, so as to realize the support and positioning of the screw rod 13, avoid the dislocation of the screw rod 13 when the compensator is subjected to the radial force, and protect the normal operation of the compensator.

[0050] Further, the two limiting pieces are respectively installed at the upper and lower ends of one screw rod 13, which can stably protect the screw rod 13 to be always parallel to the center line of the compensator.

[0051] The two vertical sliding frames 20 are respectively slidingly connected with a side sliding block 24, the two side sliding blocks 24 are connected with a pressing spring 23 at one end of the inner wall of the vertical sliding frame 20, the inner end of the two side sliding blocks 24 is fixedly connected with a top hollow outer cylinder block 25, and the top inner wall of the outer cylinder block 25 is uniformly fixedly connected with a plurality of wedge blocks 29 which are inclined in the same direction.

[0052] The outer cylinder block 25 is rotatably connected with a top hollow inner rotating block 26, the inner wall of the inner rotating block 26 is sequentially provided with a plurality of limiting grooves 27 with gradually increasing sizes from top to bottom, the limiting grooves 27 are inserted with the screw cap 14 and the top end of the screw rod 13, and the top outer wall of the limiting grooves 27 is uniformly fixedly connected with a plurality of spring sheets 28.

[0053] Further, the number of the wedge blocks 29 is not less than 3 groups, and the number of the wedge blocks 29 is correspondingly arranged with the spring sheets 28.

[0054] Among them, the spring sheets 28 are blocked by the wedge blocks 29 when rotating in the loosening direction of the screw cap 14, and the spring sheets 28 slide with the inclined surface of the wedge blocks 29 when rotating in the tightening direction of the screw cap.

[0055] Referring toFigures 6-10 The outer cylinder block 25 is slid in the vertical sliding frame 20 through the side sliding block 24, the outer cylinder block 25 rotates with the connecting position of the side sliding block 24 and the vertical sliding frame 20 as the fulcrum, and the outer cylinder block 25 cannot rotate along its axis; the outer cylinder block 25 can adapt to the sliding and inclination change of the connected nut 14 on one hand, and on the other hand, through the two connection states of the spring sheet 28 and the wedge block 29, it ensures that the inner rotating block 26 cannot rotate in the loosening direction of the clamped nut 14, so as to ensure the stability of the equipment connection.

[0056] Further, the multiple size levels of the limiting notches 27 can adapt to different sizes of the nut 14, and can all realize the limitation of the nut 14, so as to ensure the stability of the compensator connection.

[0057] Specifically, the inner rotating block 26 rotates in the middle groove of the inner wall of the outer cylinder block 25 (see Figure 9 and Figure 10 ), the inner rotating block 26 rotates along the axis of the outer cylinder block 25, and under the cooperation of the spring sheet 28 and the wedge block 29, the rotation direction of the inner rotating block 26 is limited, and the compensator only generates radial (i.e. Figure 1 vertical direction) expansion and contraction force, and the inner rotating block 26 remains stable, and its rotation only exists in the lateral shaking.

[0058] The support member includes two side plates one 5 symmetrically and fixedly connected to the outer wall of the end pipe one 1, the outer sides of the two side plates one 5 are respectively vertically fixedly connected with a middle plate 6, and the outer walls of the two middle plates 6 are both provided with a horizontal notch one 7.

[0059] The support member further includes two side plates two 8 symmetrically and fixedly connected to the outer wall of the end pipe two 2, the outer sides of the two side plates two 8 are respectively vertically fixedly connected with two adjacent clamping plates 9, the middle parts of the two clamping plates 9 at one side are slidably connected with the middle plate 6, and the two clamping plates 9 and the middle plate 6 are connected with a connecting bolt 10 at the notch one 7.

[0060] Referring to Figures 1-3 and Figure 5 , the notch one 7 is provided along the extension direction of the clamping plate 9, and the size is greater than that of the connecting bolt 10, so as to ensure that the middle plate 6 and the clamping plate 9 can slide adaptively when the compensator bears the axial force.

[0061] Further, another implementation manner of the support member is:

[0062] The middle plate 6 is rotationally connected with the connected side plate one 5, and the two clamping plates 9 are rotationally connected with the connected side plate two 8, so as to ensure that the device can resist the radial force.

[0063] In use, the end pipe one 1 is connected with the end pipe two 2, the inner pipe 3 is inserted into the inner wall of the end pipe two 2, the top end of the corrugated pipe 4 abuts against the bottom end of the end pipe one 1, the side plate one 5 corresponds to the side plate two 8, the middle plate 6 is matched with the clamping plate 9, and the connection of the two clamping plates 9 and the middle plate 6 is completed through the connecting bolt 10.

[0064] After the side plate one 5 is matched with the side plate two 8, each reinforcing plate 11 is also matched, the screw rod 13 is sequentially inserted through the two movable notches 12, and a supporting spring 15 is placed when the screw rod 13 is inserted through one movable notch 12, finally the bolt fixing is completed through the two nuts 14, after the fixing of all the screw rods 13 is completed, a connecting plate 17 is respectively installed and fixed at the corresponding reinforcing plate 11, and the bottom end of the inner rotating block 26 driven by the outer cylinder block 25 is clamped with the nut 14, if the limiting notch 27 and the nut 14 have not completed clamping, only need to reverse rotate the inner rotating block 26 to realize the clamping of the bottom end of the limiting notch 27 and the nut 14, and the whole equipment is completed.

[0065] The compensator is installed through the flange, when the pipeline is conveying medium, the compensator can provide composite support force under the cooperation of the elastic potential energy of the corrugated pipe 4 and the plurality of supporting springs 15 when the compensator is subjected to axial force.

[0066] When the compensator is subjected to radial force, the plurality of screw rods 13 slide along the movable notches 12 and cooperate with the corrugated pipe 4 to incline, and the screw rod 13 and the nut 14 can push the whole outer cylinder block 25 to slide outward through the reset spring 18, so that the screw rod 13 is always parallel to the center line of the compensator.

[0067] Under the vibration generated by conveying medium, after the inner rotating block 26 is clamped with the nut 14, through the connection of the spring sheet 28 and the wedge block 29, the whole nut 14 and the screw rod 13 cannot rotate in the loosening direction, so that the stable operation of the compensator is ensured.

[0068] In the embodiment, the size and size ratio of each structure are reasonably selected according to the working needs of the actual compensator.

[0069] Among them:

[0070] When the end pipe one 1 and the end pipe two 2 bear axial force, the corrugated pipe 4 will synchronously expand and contract in the axial direction with the supporting spring 15, and the compensation range is 0-40mm (the specific value needs to be changed according to the size ratio of the equipment and the pipeline conveying pressure value).

[0071] When the end pipe one 1 and the end pipe two 2 bear radial force, the corrugated pipe 4 deforms towards the bearing area and compensates, so that at the tail of the screw rod 13 and the connection of the nut 14, the outer cylinder block 25 and the arc block 19 slide along the radial sliding groove 21 inwards / outwards, realize the radial displacement compensation of the outer cylinder block 25 and the arc block 19 consistent with the end pipe one 1 and the end pipe two 2, and finally realize the homing of the outer cylinder block 25 driving the nut 14 through the reset spring 18.

[0072] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely divergences of the principles and spirit of the application and that numerous modifications, changes, substitutions, and alterations can be made thereto without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
