Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline fixing equipment, and specifically relates to a pier support. Background Technology

[0002] Pipeline anchors are important hydraulic structures used to secure pipelines, typically made of reinforced concrete. They are mainly used for the outlet pipes of hydropower stations and pumping stations, as well as the pressure pipes of water supply projects, to fix the pressure pipelines and prevent displacement. They are generally built at pipeline bends; when a straight pipeline is too long, anchors may also be installed at corresponding positions in the middle of the pipeline.

[0003] During the construction of the anchor block, a reserved trench needs to be dug in the foundation below the section of the pipeline to be supported. There is a certain gap between the pipeline and the reserved trench, that is, the section to be supported is in a suspended state. Then, concrete is poured in the reserved trench to cover the section to be supported. After the concrete solidifies, the anchor block is formed, which fixes the section to be supported to the foundation, ensuring the stable operation of the pipeline.

[0004] However, during the construction of the anchor block, the lack of support for the section to be supported causes it to bend and deform downwards under the influence of gravity. Fixing the deformed section to be supported to the foundation with the anchor block will make the pipeline prone to damage during subsequent use, thus reducing the service life of the pipeline. Utility Model Content

[0005] This utility model provides a pier support to solve the technical problem in the prior art where the pier construction process lacks support for the section to be supported, causing the section to be supported to bend and deform downward under gravity, which leads to easy damage to the fixed pipeline during subsequent use and thus reduces its service life.

[0006] To solve the above problems, this utility model is achieved through the following technical solution:

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] In the embodiments of this application, such as Figures 1 to 6 As shown, the town pier support includes a lifting rod 3 and a support base 1; wherein,

[0043] The upper end face of the support base 1 is provided with a first arc-shaped groove 11 that fits the lower surface of the section 4 to be supported, see [reference]. Figure 4 The first arc-shaped groove 11 is a through groove, and the extension direction of the first arc-shaped groove 11 is the same as the extension direction of the section 4 to be supported.

[0044] There are multiple lifting rods 3, which are evenly distributed on the lower end face of the support base 1 to jointly adjust the height of the support base 1.

[0045] Before pouring concrete, the workers can first place the town pier support in the reserved groove and adjust the height of the lifting rod 3 so that the first arc groove 11 on the support seat 1 fits the lower surface of the section 4 to be supported, so as to avoid the section 4 to be supported from bending and deforming downward under the action of gravity.

[0046] Then, the staff can install the pouring template along the edge of the reserved groove, and surround the town pier support with the pouring template, so that the concrete pouring work can be carried out.

[0047] Specifically, the mixed concrete is poured into the gap between the casting formwork and the support frame, and the support frame and the section 4 to be supported are fixed together with the concrete. After the concrete solidifies, it can form a support frame together with the support frame, so as to effectively support and fix the section 4 to be supported, thereby ensuring the service life of the pipeline.

[0048] Furthermore, the installation of this pier support can simplify the pier construction process. Normally, after excavating the reserved trench, the bottom of the trench needs to be leveled. However, the pier support in this embodiment eliminates the need for this leveling step during use. The specific operation is as follows:

[0049] After the excavation of the reserved slot is completed, the staff can determine the height of the support seat 1 by adjusting the height of multiple lifting rods 3. That is, reduce the length of the lifting rod 3 corresponding to the protruding part of the bottom of the reserved slot and increase the length of the lifting rod 3 corresponding to the concave part of the bottom of the reserved slot, so that the multiple lifting rods 3 can stably support the support seat 1 in the reserved slot and ensure that the plane of the lower end face of the support seat 1 is parallel to the horizontal plane, so that the support seat 1 can better support the section 4 to be supported.

[0050] During this process, there is no need to level the bottom of the reserved groove. The lower end of the support base 1 can be adjusted to be parallel to the horizontal plane simply by adjusting the length of the lifting rod 3, so as to achieve stable support for the section to be supported 4, thus making the construction of the pier easier.

[0051] In some embodiments, the pier support also includes a connecting seat 2, see [link to previous document]. Figure 1 , Figure 3 and Figure 5 ;in,

[0052] The lower end face of the connecting seat 2 is provided with a second arc-shaped groove 21. The second arc-shaped groove 21 is a through groove. The extension direction of the second arc-shaped groove 21 is the same as the extension direction of the section 4 to be supported. The connecting seat 2 is detachably set on the upper end face of the support seat 1. The shape formed by the first arc-shaped groove 11 and the second arc-shaped groove 21 matches the shape of the section 4 to be supported, so as to better fix the section 4 to be supported and realize the support and fixation of the section 4 to be supported.

[0053] Preferably, a first mounting base 13 is provided on the side wall of the support base 1, see [reference]. Figure 3 The first mounting base 13 is provided with a first through hole, and the axis of the first through hole is perpendicular to the horizontal plane;

[0054] The connecting seat 2 is provided with a second mounting seat 24 at the position corresponding to the first mounting seat 13, and the second mounting seat 24 is provided with a second through hole at the position corresponding to the first through hole;

[0055] When installing the connecting seat 2, the connecting end of the bolt is passed through the second through hole and the first through hole in sequence and then connected to the nut. The nut is then tightened to connect the connecting seat 2 to the support seat 1.

[0056] In some embodiments, the extension directions of the first arc-shaped groove 11 and the second arc-shaped groove 21 described above are both curves. In this embodiment, the height of the inlet end of the section to be supported 4 is greater than the height of the outlet end of the section to be supported 4. The inlet end of the section to be supported 4 smoothly transitions to the outlet end of the section to be supported 4. The axis of the outlet end of the section to be supported 4 is parallel to the horizontal plane. See [reference needed]. Figure 1 ;

[0057] The inclined section at the bottom of the second arc-shaped groove 21 is equipped with a buffer 22 to reduce the lateral vibration of the section 4 to be supported. The buffer 22 absorbs the impact force on the section 4 to be supported, thereby reducing the vibration of the section 4 to be supported and protecting the pipeline.

[0058] It is worth noting that, since the second arc-shaped groove 21 is located on the lower end face of the connecting seat 2, the bottom of the second arc-shaped groove 21 refers to the position opposite to the bottom of the first arc-shaped groove 21. That is, the bottom of the second arc-shaped groove 21 is located directly above the bottom of the first arc-shaped groove 21, and the height of the bottom of the second arc-shaped groove 21 is greater than the height of the opening of the second arc-shaped groove 21. See [reference needed]. Figure 3 and Figure 5 .

[0059] In some embodiments, the inclined section at the bottom of the second arc-shaped groove 21 is provided with a mounting groove, the extending direction of which is parallel to the horizontal plane. (See also...) Figure 5 ;

[0060] The buffer component 22 includes a mounting cylinder 221, a top plate 222, a top rod 223, and a buffer spring 224. See below. Figure 2 ;in,

[0061] The mounting cylinder 221 is disposed in the mounting groove, and an opening is provided at the end of the mounting cylinder 221 that is away from the mounting groove.

[0062] The push rod 223 is slidably disposed in the mounting cylinder 221 in the horizontal direction, and an abutment block is provided on the side wall of the push rod 223;

[0063] The buffer spring 224 is disposed between the abutment block and the bottom of the mounting cylinder 221;

[0064] The top plate 222 is located at the end of the top rod 223 away from the mounting cylinder 221, and the side of the top plate 222 facing away from the top rod 223 abuts against the section 4 to be supported;

[0065] When the section 4 to be supported is subjected to an impact force and presses against the top plate 222, that is, when the section 4 to be supported is subjected to an impact force and vibrates laterally, the top plate 222 will transmit the impact force to the buffer spring 224 through the top rod 223. The buffer spring 224 absorbs the impact force to play a role in buffering and shock absorption.

[0066] In some embodiments, the inclined section at the bottom of the second arc-shaped groove 21 described above is provided with a receiving groove 23, see [reference]. Figure 2 and Figure 5 ;in,

[0067] The shape of the receiving groove 23 matches the shape of the top plate 222 so that the top plate 222 can be fully embedded in the receiving groove 23;

[0068] Furthermore, when the top plate 222 is impacted by the section to be supported 4 and embedded into the receiving groove 23, the side of the top plate 222 facing away from the top rod 223 coincides with the groove wall of the inclined section at the bottom of the second arc-shaped groove 21. This prevents the top plate 222 from being squeezed by the section to be supported 4 and the connecting seat 2, thus avoiding damage to the top plate 222 or deformation of the section to be supported 4. Of course, the coverage area of ​​the receiving groove 23 can be larger than the coverage area of ​​the top plate 222 to better accommodate the top plate 222.

[0069] It is worth noting that when the section 4 to be supported is fixed by the support seat 1 and the connecting seat 2, when pouring concrete, it is possible to pour only up to the height of the support seat 1, and use the concrete to cover the support seat 1 to fix the support seat 1. Then, the section 4 to be supported is fixed by the support seat 1 and the connecting seat 2, so that the section 4 to be supported can be fixed together with the foundation by the pier support and the pier formed by the concrete.

[0070] In the prior art, when pipeline maintenance is required, it is necessary to remove the reinforced concrete support piers, which is difficult and complicated. In this embodiment, it is only necessary to remove the connecting seat 2 from the support seat 1 to remove the pipeline section 4 to be supported from between the connecting seat 2 and the support seat 1, thereby making pipeline maintenance more convenient.

[0071] In some embodiments, the lifting rod 3 described above includes a support plate 31, a sleeve 32, a lifting nut 33, and a threaded rod 34 that matches the lifting nut 33. See [reference needed]. Figure 6 ;in,

[0072] The sleeve 32 is a hollow tubular structure. One end of the sleeve 32 is rotatably mounted on the support plate 31, and the lifting nut 33 is fixedly mounted on the other end of the sleeve 32. The threaded hole on the lifting nut 33 is connected to the interior of the sleeve 32. The axis of the lifting nut 33 coincides with the axis of the sleeve 32 and is perpendicular to the plane where the support plate 31 is located.

[0073] The threaded rod 34 is screwed into the lifting nut 33, and the end of the threaded rod 34 away from the support plate 31 is connected to the lower end face of the support seat 1.

[0074] When it is necessary to adjust the length of the lifting rod 3, the operator can turn the lifting nut 33 to make the lifting nut 33 and the threaded rod 34 rotate relative to each other. Under the action of the thread, the relative position of the lifting nut 33 and the threaded rod 34 will change, so as to complete the adjustment of the length of the lifting rod 3.

[0075] In this embodiment, when the town pier support is placed in the reserved groove, the support plate 31 contacts the bottom of the reserved groove;

[0076] When the height of the support base 1 needs to be adjusted, the operator can directly turn the lifting nut 33. The sleeve 32 will move together with the lifting nut 33, and the lifting nut 33 and the threaded rod 34 will rotate relative to each other to adjust the length of the lifting rod 3, thereby adjusting the height of the support base 1.

[0077] Preferably, the end of the threaded rod 34 away from the support plate 31 is fixedly connected to the lower end face of the support base 1.

[0078] In some embodiments, a first buffer pad 111 is provided in the first arc-shaped groove 11 described above, see [link to previous document]. Figure 4 ;

[0079] The first buffer pad 111 can play a role in shock absorption and protection, thereby reducing the impact force on the section 4 to be supported and preventing the section 4 to be supported from directly contacting the support seat 1, which would cause wear on the section 4 to be supported, thus improving the service life of the pipeline.

[0080] Preferably, the first arc-shaped groove 11 is provided with a limiting block 12 to restrict the sliding of the first buffer pad 111 along the extending direction of the section to be supported 4, thereby preventing the first buffer pad 111 from coming off the first arc-shaped groove 11. In this embodiment, the height of the inlet end of the section to be supported 4 is greater than the height of the outlet end of the section to be supported 4. By placing the limiting block 12 at the outlet end of the first arc-shaped groove 11 corresponding to the outlet end of the section to be supported 4, the first buffer pad 111 can be effectively prevented from coming off along the first arc-shaped groove 11 toward the outlet end of the section to be supported 4, thus making the structure more stable.

[0081] In some embodiments, the height of the limiting block 12 is less than the thickness of the first buffer pad 111 when it reaches the compression limit.

[0082] When the pipeline is subjected to impact, the section 4 to be supported in the pipeline will squeeze the first buffer pad 111, thereby protecting the section 4 to be supported. When the impact force is too great, causing the first buffer pad 111 to be compressed to its limit, the limiting block 12 will still not contact the section 4 to be supported, thereby avoiding damage to the section 4 to be supported and extending the service life of the pipeline.

[0083] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
