DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Figures 1-9 It is obvious that the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.
[0030] In order to solve the problems in the prior art, the embodiment provides a supporting device for water conservancy and hydropower construction, which comprises a steel strand 7 and a clamping sleeve 1 sleeved on the outer walls of two butt pipelines 4, two clamping sleeves 1 are respectively abutted on the flanges 5 of the ports of the corresponding pipelines 4, a plurality of anchor hooks 6 are annularly arranged on the two clamping sleeves 1, the anchor hooks 6 on the two clamping sleeves 1 are staggered, the fixed end of the steel strand 7 is fastened on one anchor hook 6, and the movable end of the steel strand 7 is sequentially and alternately threaded through the anchor hooks 6 on the two clamping sleeves 1 and the movable end of the steel strand 7 is fastened and installed on the clamping sleeve 1.
[0031] According to the above technical solutions:
[0032] In use, the two clamping sleeves 1 are respectively sleeved on the outer walls of two groups of pipelines 4 to be connected, one end of the steel wire 7 is fixed on the anchor hook 6 of one of the clamping sleeves 1, and then the steel wire 7 is sequentially passed through the anchor hooks 6 on the two clamping sleeves 1 in an interlaced order. By pulling and tightening the steel wire 7, the steel wire 7 pulls the two clamping sleeves 1 close to each other, and the two clamping sleeves 1 abut against the flanges 5 to make the pipe openings of the two pipelines 4 close to each other and tend to be aligned. After the connection of the pipelines 4 is completed, the movable end of the steel wire 7 is fastened on the clamping sleeve 1 through the anchor.
[0033] Compared with the traditional measures such as bundling and buckling, the present scheme can be used when the pipelines 4 are not placed, and can assist in connecting the pipelines 4; after the connection is completed, the two clamping sleeves 1 can also support the pipelines 4. When leakage occurs at the connection of the pipelines 4, the pipelines 4 can be connected more tightly by tightening the steel wire 7 again, thereby reducing the leakage amount to facilitate subsequent maintenance and inspection work.
[0034] In the present scheme, in order to avoid the influence of the clamping sleeve 1 on the connection of the flanges 5 of the two pipelines 4 and the installation of the bolts on the flanges 5, the structure of the clamping sleeve 1 is set as follows: the clamping sleeve 1 comprises an inner ring 101, an outer ring 102, and a hub 103 connecting the inner ring 101 and the outer ring 102, and a plurality of channels 104 are arranged in an annular array on the hub 103. The periphery of the channel 104 is provided with a rib plate. The outer wall of the inner ring 101 is located in the inner circle of the mounting hole of the flange 5. The mounting hole of the flange 5 is leaked through the channel 104, and the insertion and installation of the bolts are not affected.
[0035] In a further embodiment of the present scheme, a specific structure for erecting two clamping sleeves 1 is provided in the present embodiment: a support is provided, and the support comprises two groups of arch supports 13. The lower end of the arch support 13 is provided with a supporting leg 14. The two ends of the two arch supports 13 are each provided with a insertion hole. A guide column 15 is inserted into the insertion holes on the same side of the two arch supports 13. The side wall of the clamping sleeve 1 is provided with a lug 8, the center of the lug 8 is provided with an inner hole, and the guide column 15 penetrates the lug 8.
[0036] According to the above technical scheme:
[0037] When the pipelines 4 are connected, the arch supports 13 can be placed under the two pipelines 4 in advance to lift the pipelines 4. After the steel wire 7 is tightened and the connection of the pipelines 4 is completed, the two pipelines 4 are aligned, and the lugs 8 on the two pipelines 4 are aligned. Then, the positions of the two arch supports 13 are adjusted so that the insertion holes on the arch supports 13 are aligned with the inner holes of the lugs 8. Then, the guide column 15 is sequentially inserted into the insertion holes, the inner holes of the lugs 8, the inner holes of the lugs 8, and the insertion holes, thereby achieving the connection of the arch supports 13 and the clamping sleeves 1, and thereby axially limiting the clamping sleeves 1.
[0038] Through the component, the lifting of the clamping sleeve 1 can be realized, and the clamping sleeve 1 can be guided and limited, and then the dislocation of the pipeline 4 structure is limited, and the alignment consistency of the pipeline 4 to the interface is ensured.
[0039] Preferably, a limiting mechanism such as a bolt is arranged on the guide column 15 at both sides of the lug 8. The lug 8 is limited, and the sliding of the clamping sleeve 1 on the guide column 15 is prevented, so as to affect the clamping consistency.
[0040] In a further embodiment of the embodiment 3, two tightening sleeves 2 are further arranged on the pipeline 4, and the outer wall of the tightening sleeve 2 and the inner wall of the clamping sleeve 1 are conical surfaces matched with each other. The outer eaves 3 are arranged at opposite ends of the two tightening sleeves 2, and the outer eaves 3 abut against the flanges 5 of the pipeline 4. The opposite ends of the two tightening sleeves 2 are both annularly arrayed with a plurality of openings 9.
[0041] Compared with the original auxiliary pipe port butt joint, only the two clamping sleeves 1 abut against the flanges 5, the stress points are only on the contact surfaces of the clamping sleeves 1 and the flanges 5, and attention needs to be paid to avoid interfering with the bolt connection of the flanges 5. In the use of the embodiment, the connection area is increased by the outer eaves 3, and the stress points are expanded. In the process of tensioning the steel strand 7, the inner conical surface of the clamping sleeve 1 abuts against the outer conical surface of the tightening sleeve 2 and approaches each other, the inner conical surface and the outer conical surface are extruded, the end of the opening 9 of the tightening sleeve is tightened, and the tightening sleeve 2 is tightly buckled on the outer wall of the pipeline 4, so as to increase the connection tightness between the tightening sleeve 2 and the pipeline 4 and the clamping limiting capacity. At the same time, through the slope cooperation of the inner conical surface and the outer conical surface, the spacing between the clamping sleeve 1 and the flanges 5 of the pipeline 4 is further expanded after the butt joint of the pipeline 4 is completed, and more sufficient space is provided for the screwing and dismounting of the nut.
[0042] In the scheme, in order to facilitate the installation of the clamping sleeve 1 and the tightening sleeve 2 on the pipeline 4, the clamping sleeve 1 and the tightening sleeve 2 can be divided into two semicircles. During installation, the two are contacted and then fastened by bolts, so as to be combined into a complete ring. The bolt installation position of the tightening sleeve 2 is located in the non-opening 9 area. The two half clamping sleeves 1 can also be welded and fixed at the contact end, forming a whole. At this time, the tightening sleeve 2 can also be placed at the inner conical surface of the clamping sleeve 1 as two halves. The two halves of the tightening sleeve 2 are installed separately, which does not affect the installation and use.
[0043] In the scheme, in order to further improve the convenience of tightening the steel strand 7, a rotating shaft 10 is rotatably arranged on the clamping sleeve 1 at the fixed end of the steel strand 7. A winding wheel 11 is arranged on the rotating shaft 10, a hook is arranged on the winding wheel 11, and a hook is arranged at both ends of the steel strand 7. A ratchet structure is arranged between the rotating shaft 10 and the tightening sleeve 2 for one-way limiting. A regular deformation column head is arranged at the upper end of the rotating shaft 10, and the structure is similar to a nut.
[0044] In use, the hook at one end of the steel strand 7 is hung on the anchor hook 6, and the hook at the other end is hung on the anchor hook 6 in turn and then hung on the hook of the winding wheel 11. Then the wrench is put on the column head to rotate the rotating shaft 10, the rotating shaft 10 drives the winding wheel 11 to rotate, and then the steel strand 7 is wound, and then the two clamping sleeves 1 are tightly connected. It is more convenient to use. The rotating shaft 10 is limited by the ratchet structure, so that the steel strand 7 cannot be easily loosened after being wound.
[0045] The ratchet structure includes a ratchet and a pawl, the ratchet is fixed on the rotating shaft 10, the pawl is rotatably installed on the support on the side of the rotating shaft 10 of the clamping sleeve 1, and the pawl and the support are provided with an elastic element such as a tension spring. The pawl abuts between the teeth of the ratchet. The side of the pawl is provided with a pull rope, and the end of the pull rope is provided with a pull ring. When the pull ring is pulled, the pawl is driven to deviate and separate from the ratchet, so that the brake of the rotating shaft 10 is disabled, and the steel strand 7 can be loosened at this time.
