Description

Technical Field

[0001] The present invention relates to the technical field of bellows butt jointing, in particular to a bellows butt jointing device. Background Art

[0002] Bellows are tubular elastic sensitive elements constructed from foldable corrugated sheets connected along the folding and contracting directions. Bellows are widely used in instrumentation, primarily as measuring elements in pressure gauges, converting pressure into displacement or force. Bellows have thin walls and high sensitivity, with a measurement range of tens of Pa to tens of MPa. The open end is fixed, while the sealed end is free, and an auxiliary coil spring or reed is used to increase its elasticity. During operation, the bellows expands along its length under the action of internal pressure, causing the movable end to displace in a manner proportional to the pressure.

[0003] The existing bellows connecting device can only lift and lower the bellows. When docking the bellows in the middle position (that is, both ends of the bellows to be installed need to be connected), the bellows cannot be accurately extended to the appropriate length on the ground, resulting in the bottom moving mechanism needing to move continuously during installation to install the two ends of the bellows to the specified positions respectively.

[0044] Embodiment:

[0045] Refer to Figure 1The embodiment of the present invention discloses a bellows docking device, which includes a movable base 100, a lifting base 200, a sliding base 300, and two support structures 400. The lifting base 200 is mounted on the movable base 100, and the sliding base 300 is mounted on the lifting base 200. One support structure 400 is mounted on the lifting base 200, and the other support structure 400 is mounted on the sliding base 300. The two ends of the bellows 500 are respectively mounted on the two support structures 400. The movable base 100 can drive the bellows 500 to move, the lifting base 200 can adjust the height of the bellows 500, and when the sliding base 300 slides, the bellows 500 can be stretched or shortened to facilitate docking.

[0046] The bellows docking device disclosed in this embodiment uses a sliding seat 300 to control the length of the bellows 500. During the installation process, the length of the bellows 500 can be adjusted to an appropriate length by simply moving the sliding seat 300. The movable seat 100 at the bottom does not need to continue moving after reaching the appropriate position, making it more convenient to operate.

[0047] See Figures 1 to 3 The movable base 100 can be a carrier such as a car. The movable base 100 is mainly used to drive the various components to move on the bottom surface so as to send the bellows 500 to the bottom of the installation position. The lifting base 200 is mainly used to drive the bellows 500 to move up and down so as to send the bellows 500 to a suitable height. The lifting base 200 is connected to the movable base 100 through a structure such as a hydraulic cylinder. When the hydraulic cylinder is working, it can drive the lifting base 200 to move up and down. One end of the lifting base 200 is higher and the other end is lower. The sliding base 300 is installed at the lower end of the lifting base 200 so that the top surface of the sliding base 300 is flush with the top surface of the higher end of the lifting base 200. In this way, after the two support structures 400 are respectively installed on the lifting base 200 and the sliding base 300, the heights of the two support structures 400 are exactly the same.

[0048] See Figure 3 A guide rail 210 is provided on the lifting base 200, and the sliding base 300 is slidably engaged with the guide rail 210. The bellows docking device also includes a control motor 220 and a screw rod 230. The control motor 220 is mounted on the lifting base 200 and is in driving connection with the screw rod 230. The screw rod 230 is threadedly connected to the sliding base 300.

[0049] See Figure 4, the support structure 400 includes an adjustment component 410 and a fixing component 420. The adjustment component 410 includes a first connection seat 411, a second connection seat 412, and a third connection seat 413. One of the third connection seats 413 is installed on the sliding seat 300, and the other connection seat is installed on the lifting seat 200. The second connection seat 412 is rotatably connected to the third connection seat 413, and the rotation axis of the second connection seat 412 is arranged along the height direction of the moving seat 100. The first connection seat 411 is rotatably connected to the second connection seat 412. The rotation axis of the first connection seat 411 is perpendicular to the moving direction of the sliding seat 300, and the rotation axis of the first connection seat 411 is perpendicular to the rotation axis of the second connection seat 412. The use of the adjustment structure can adjust the orientation of the port of the bellows 500, thereby realizing the rapid installation of the bellows 500. The two support seats respectively adjust the two end faces of the bellows 500 to ensure that even if the orientations of both ends of the bellows 500 need to be inclined to each other after installation, rapid adjustment and installation can be achieved. A card slot is provided on the first connection seat 411. The card slot is arc-shaped, and the central angle corresponding to the card slot is less than 180 degrees. When the bellows 500 is placed on the support structure 400, the flange of the bellows 500 is just clamped in the card slot to ensure that when the sliding seat 300 drives the support structure 400 to move, it can drive the end of the bellows 500 to move, thereby realizing the change in the length of the bellows 500.

[0050] In this embodiment, the rotation of the second connection seat 412 and the rotation of the first connection seat 411 can both be driven by motors.

[0051] Refer to Figures 5 to 11 , the fixing component 420 includes a fixing arc piece 421, a first slider 423, a connecting rope 424, a first elastic member 425, and a fixing buckle ear 422. The fixing arc piece 421 is rotatably connected to the first connection seat 411. The rotation axis of the fixing arc piece 421 is parallel to the sliding direction of the sliding seat 300, and when the bellows 500 is installed on the fixing arc piece 421, the fixing arc piece 421 can just drive the bellows 500 to rotate along its axis when rotating. When the bellows 500 is connected and installed, the ports are usually connected by flanges. Such a connection method has connection holes provided on the end flanges. Only when the connection holes on the to-be-installed bellows 500 and the installed bellows 500 are aligned can the bellows 500 be connected. When people place the bellows 500 on the fixing arc piece 421, it is impossible to ensure that the connection holes on the bellows 500 are just aligned with the connection holes of the installed bellows 500 after the bellows 500 is sent to the designated position. At this time, driving the bellows 500 to rotate along its axis by the fixing arc piece 421 can adjust the position of the connection holes, so that the connection holes on the to-be-installed bellows 500 are aligned with the connection holes on the installed bellows 500.

[0052] It should be noted that in this embodiment, the corrugated pipe 500 transported to the designated position by the corrugated pipe docking device is the corrugated pipe 500 to be installed, while the corrugated pipe 500 that has been fixed in the preset position in advance is the corrugated pipe 500 to be installed.

[0053] Refer to Figures 4 to 11 , the fixing assembly 420 further includes structures such as a first slider 423 for clamping and fixing the corrugated pipe 500, a connecting rope 424, a first elastic member 425, and a fixing buckle ear 422. The fixing buckle ear 422 is installed at the end of the fixing arc piece 421. There are two fixing buckle ears 422, and the two fixing buckle ears 422 are respectively arranged at the two ends of the fixing arc piece 421. Refer to Figure 4 , a fixing groove is provided on the fixing buckle ear 422. When the buckle ear moves radially inward along the fixing arc piece 421, the flange of the corrugated pipe 500 will be stuck in the fixing groove, so as to realize the fixation of the fixing arc piece 421 and the corrugated pipe 500. The fixing buckle ear 422 is slidably connected to the fixing arc piece 421, and the fixing buckle ear 422 can slide relative to the fixing arc piece 421 along the radial direction of the fixing arc piece 421. When both fixing buckle ears 422 move radially inward along the fixing arc piece 421, the corrugated pipe 500 located on the fixing arc piece 421 can be clamped.

[0054] The first slider 423, the connecting rope 424, and the first elastic member 425 are mainly used to control the position of the fixing buckle ear 422. Specifically, both ends of the first elastic member 425 are respectively connected to the fixing arc piece 421 and the fixing buckle ear 422, and the first elastic member 425 makes the fixing buckle ear 422 have a tendency to slide radially outward along the fixing arc piece 421. Both ends of the connecting rope 424 are respectively connected to the first slider 423 and the fixing buckle ear 422, and the first slider 423 is slidably connected to the fixing arc piece 421. When the first slider 423 moves radially outward along the fixing arc piece 421, the connecting rope 424 pulls the fixing buckle ear 422 to move radially inward along the fixing arc piece 421. Refer to Figure 6 and Figure 10, the first slider 423 can be arranged at the middle position of the fixed arc piece 421. Initially, under the elastic force of the first elastic piece 425, the fixed buckle ear 422 slides outwards. At this time, the fixed buckle ear 422 pulls the first slider 423 through the connecting rope 424, making the slider protrude from the inner wall of the fixed arc piece 421. When the corrugated pipe 500 is placed on the fixed arc piece 421, the gravity of the corrugated pipe 500 is used to make the first slider 423 move radially outwards along the fixed arc piece 421. When the first slider 423 moves outwards, it pulls the fixed buckle ear 422 through the connecting rope 424. At this time, the fixed buckle ear 422 moves inwards against the elastic force of the first elastic piece 425. When the corrugated pipe 500 is completely placed on the fixed arc piece 421, the upper end surface of the first slider 423 is just flush with the inner wall of the fixed arc piece 421, and at this time, the two buckle ears move inwards just to clamp the flange of the corrugated pipe 500. Due to the relatively large weight of the long corrugated pipe 500, generally when the fixed arc piece 421 rotates, the corrugated pipe 500 is prone to slipping, that is, when the fixed arc piece 421 rotates, the corrugated pipe 500 does not rotate. After setting the above-mentioned fixed buckle ear 422 and other structures, the connection tightness between the fixing component 420 and the corrugated pipe 500 can be strengthened, so as to ensure that when the fixed arc piece 421 rotates, the corrugated pipe 500 can rotate together with the fixed arc piece 421.

[0055] In this embodiment, the connecting rope 424 is made of an elastic material, which can avoid the deformation of the flange due to excessive pressure of the fixed buckle ear 422 on the flange of the corrugated pipe 500 or the damage of the fixed buckle ear 422. In addition, an electric cylinder 426 for controlling the fixed buckle ear 422 can also be arranged on the fixed arc piece 421. By using this electric cylinder 426, the fixed buckle ear 422 can be pushed to move, so as to ensure that after the installation of the corrugated pipe 500 is completed, the fixed buckle ear 422 is separated from the corrugated pipe 500, and then the fixed arc piece 421 rotates to the initial position, so that when the lifting seat 200 lifts, the fixed arc piece 421 can be separated from the corrugated pipe 500.

[0056] Specifically, the electric cylinder 426 is arranged on the outer wall of the fixed arc piece 421, the output end of the electric cylinder 426 faces the fixed buckle ear 422, and the normal state of the electric cylinder 426 is the contracted state. When the electric cylinder 426 contracts, the fixed buckle ear 422 can slide relative to the fixed arc piece 421 at will. After the installation of the corrugated pipe 500 is completed, the electric cylinder 426 works and pushes the fixed buckle ear 422 to move outwards. After the fixed arc piece 421 is separated from the corrugated pipe 500, the electric cylinder 426 returns to the contracted state.

[0057] Refer to Figure 7 、 Figure 8 and Figure 11 , a structure for detecting whether the corrugated pipe 500 is firmly connected to the fixed arc piece 421 is also arranged on the support structure 400. Specifically, refer to Figure 8, a first chute 4211 and a wire hole 4212 are provided on the fixed arc piece 421. The wire hole 4212 is arranged along the length direction of the fixed arc piece 421. The connecting rope 424 is located in the wire hole 4212. The first chute 4211 penetrates the fixed arc piece 421 along the radial direction of the fixed arc piece 421, and the first slider 423 is located in the first chute 4211. A second chute 4111 is provided on the first connecting seat 411. The second chute 4111 is arranged along the height direction of the first connecting seat 411, and when the fixed arc piece 421 is in the initial position, the second chute 4111 just communicates with the first chute 4211. Rotate the fixed arc piece 421 to make the first chute 4211 communicate with or disconnect from the second chute 4111.

[0058] A second slider 414 and a second elastic member 415 are provided on the first connecting seat 411, and both the second elastic member 415 and the second slider 414 are located in the second chute 4111. Two ends of the second elastic member 415 are respectively connected to the second slider 414 and the first connecting seat 411, and the second elastic member 415 makes the second slider 414 have a tendency to move towards the first slider 423. Refer to Figure 7 , initially, the first elastic member 425 pushes the fixed buckle ear 422 to move outwards, which can pull the first slider 423 to move upwards along the first chute 4211, and under the elastic force of the second elastic member 415, it can also push the second slider 414 and the first slider 423 to move upwards. At this time, a part of the second slider 414 will enter the first chute 42 / 11, making the fixed arc piece 421 unable to rotate relative to the first connecting seat 411. Refer to Figure 11 , after the corrugated pipe 500 is installed on the fixed arc piece 421, the first slider 423 is all pushed back into the first chute 4211 under the pressure of the corrugated pipe 500. At this time, the first slider 423 will push the second slider 414 to overcome the elastic force of the second elastic member 415 and return to the second chute 4111. When the upper end surface of the first slider 423 is flush with the inner wall of the fixed arc piece 421, the bottom surface of the first slider 423 is just flush with the outer wall of the fixed arc piece 421, that is, at this time, the second slider 414 completely leaves the range of the first chute 4211, and the first slider 423 does not enter the range of the second chute 4111 either. At this time, the fixed arc piece 421 can rotate relative to the first connecting seat 411.

[0059] When the bellows 500 is not properly installed, or the connection between the bellows 500 and the fixed arc piece 421 is not secure, the first slider 423 cannot fully enter the first chute 4211. At this time, a part of the second slider 414 will be located in the first chute 4211. The second slider 414 can be used to lock the fixed arc piece 421, making the fixed arc piece 421 unable to rotate. Because when the first slider 423 has not fully returned to the first chute 4211, the two fixed buckle ears 422 cannot fasten the bellows 500. Therefore, it is necessary to check and reinstall to ensure that the fixed buckle ears 422 fasten the bellows 500, thereby avoiding the bellows 500 slipping when the fixed arc piece 421 rotates.

[0060] In order to prevent the first slider 423 from leaving the range of the first chute 4211 under the thrust of the second slider 414 when the bellows 500 is not installed, a limiting portion can be provided on the first slider 423, and then a limiting groove is provided on the fixed arc piece 421. The limiting portion and the limiting groove are in sliding fit. One end of the limiting groove facing the first connecting seat 411 extends to the outer wall of the fixed arc piece 421, and the other end of the limiting groove is spaced from the inner wall of the fixed arc piece 421. In this way, the first slider 423 can be directly installed into the first chute 4211 from the outside of the fixed arc piece 421. When the first slider 423 moves toward the inner side of the fixed arc piece 421, it is restricted by the limiting portion and the limiting groove, making the first slider 423 unable to completely leave the range of the first chute 4211, thereby ensuring the stability of the operation of the fixing assembly 420.

[0061] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
