In addition, when the external force disappears or changes, the resetting member can make the central plate and the bottom plate and / or the sliding plate and the slide rail return to the initial state, thereby avoiding large deflection of the embedded pipeline.

Detailed Embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Refer to Figures 1-3 , the present utility model defines the length direction of the buried pre-embedded pipeline as the front-back direction, and the horizontal radial direction of the pre-embedded pipeline as the left-right direction. The present utility model provides a pre-embedded pipeline support seat for gas engineering construction, and its structure includes a base, a central plate 7, a clamp, a slide rail 11, and a reset member. Sliding plates 4 are provided on both the left and right sides of the base. Slide rails 11 are respectively provided on both the front and back sides of the base. The sliding plates 4 are slidably connected to the slide rails 11 in a one-to-one correspondence along the left-right direction. The central plate 7 is frictionally connected to the base along the front-back direction. The central plate 7 is connected to the clamp through a connecting rod 6. The clamp is used to fix the pre-embedded pipeline, and the clamp is located above the base. The reset member is used to restore it to the initial state after a relative displacement occurs between the central plate 7 and the base and / or between the sliding plate 4 and the slide rail 11.

[0038] Optionally, the slide rail 11 is a cylindrical structure with an opening facing the sliding plate 4. The sliding plate 4 penetrates through the opening of the slide rail 11 and is slidably connected to the slide rail 11. Positioning holes 12 are arranged on the slide rail 11. The fixing effect of the slide rail 11 can be achieved by passing expansion bolts through the positioning holes 12. The pre-embedded pipeline support seat of the present utility model can be applied to the installation of indoor pre-embedded pipelines. At this time, the slide rail 11 can be fixed to the concrete in the excavated trench through expansion bolts; it can also be applied to the process of outdoor trench pre-embedding. At this time, it is necessary to pre-set concrete support blocks at the bottom of the trench, and the support seat can be fixed to the concrete support blocks through expansion bolts.

[0039] The base includes a support plate 1 and end plates 3. A plurality of support plates 1 are arranged in parallel, and the plurality of support plates 1 are spaced apart in the vertical direction. A central plate 7 is arranged between two adjacent support plates 1. The central plate 7 is frictionally connected to the support plate 1 along the front-back direction. Both ends of the connecting rod 6 penetrate through the support plate 1 and are respectively connected to the central plate 7 and the clamp. Two end plates 3 are fixedly connected to the left and right ends of the support plate 1. Sliding plates 4 are arranged on the sides of the two end plates 3 away from each other.

[0040] Preferably, friction plates are arranged on the opposite surfaces of the support plate 1 and the central plate 7, thereby increasing the friction force between the support plate 1 and the central plate 7.

[0041] The central plate 7 is provided with a strip-shaped through groove 8 in the front-back direction, and the support plate 1 is provided with a plurality of through holes 2 arranged opposite to the strip-shaped through groove 8. A fastener 9 penetrates through and connects the strip-shaped through groove 8 and the through holes 2. The fastener 9 is preferably a bolt and a nut. The bolt penetrates through the through hole 2 and the strip-shaped through groove 8 at the same time and is threadedly connected with the nut.

[0042] The reset member includes SMA springs 10 respectively arranged on the front and back sides of the central plate 7. The two ends of the SMA spring 10 are respectively fixedly connected to the central plate 7 and the end plate 3. The SMA spring 10, namely a Shape Memory Alloy spring, is a high-performance material that uses the superelastic characteristics of the shape memory alloy and the reset ability of the rectangular spring to consume energy. The SMA spiral spring not only has a good reset ability but also can effectively consume energy.

[0043] The central plate 7 is frictionally connected to the support plate 1 in the front-back direction. After the clamp fixes the embedded pipeline, when the embedded pipeline is axially displaced under an external force, at this time, the embedded pipeline drives the clamp and the central plate 7 to move in the front-back direction relative to the support plate 1. When the external force disappears or changes, the SMA spring 10 can drive the central plate 7 to return to the initial position, thereby avoiding a large deflection phenomenon of the embedded pipeline.

[0044] In addition, the reset member further includes a blocking block 13 slidably connected in the slide rail 11. Two blocking blocks 13 are slidably connected in each slide rail 11, and the two blocking blocks 13 are respectively located on the left and right sides of the sliding plate 4. An elastic member is used to drive the blocking block 13 to move towards the sliding plate 4. When the sliding plate 4 is displaced in the left-right direction, the blocking block 13 can drive the sliding plate 4 to return to the initial state under the action of the elastic member.

[0045] Preferably, the left and right ends of the sliding plate 4 are respectively provided with a first inclined surface 5, and the first inclined surface 5 inclines towards the blocking block 13. One end of the blocking block 13 close to the sliding plate 4 is provided with a second inclined surface 14, and the second inclined surface 14 is arranged parallel to the first inclined surface 5.

[0046] Specifically, the elastic member includes a telescopic rod 15 extending in the left-right direction and a compression spring 16 embedded in the telescopic rod 15. One end of the telescopic rod 15 is fixedly connected to the slide rail 11, and the other end is fixedly connected to the blocking block 13. One end of the compression spring 16 is connected to the slide rail 11, and the other end is connected to the blocking block 13.

[0047] In a specific embodiment of the present utility model, in the initial state, there is a clearance fit between the sliding plate 4 and the two blocking blocks 13. When the embedded pipeline is fixed by the clamp and the embedded pipeline undergoes a radial displacement, at this time, the sliding plate 4 will move on the slide rail 11, and further will come into contact with one of the blocking blocks 13, driving the compression spring 16 connected to the blocking block 13 in contact with it to compress. After the compression spring 16 compresses, a restoring force is generated, which can gradually drive the blocking block 13 and the sliding plate 4 to return to the initial state when the external force disappears or changes, that is, driving the sliding plate 4 to be located between the two blocking blocks 13 again. Thus, it effectively avoids the large deflection of the embedded pipeline caused by the excessive movement range of the base.

[0048] The clamp is composed of a lower seat 17 with a semi-circular cross-section and an upper seat 18, and the lower seat 17 and the upper seat 18 enclose a circular ring. The lower seat 17 is fixedly connected to the connecting rod 6, one end of the upper seat 18 is hinged to one end of the lower seat 17, and the other end of the upper seat 18 is detachably connected to the other end of the lower seat 17 through a fastener 9. Anti-slip washers 19 are fixedly connected to the inner side walls of the upper seat 18 and the lower seat 17, and the anti-slip washers 19 are preferably made of rubber material.

[0049] The working principle of the present utility model:

[0050] First, complete the connection between the center plate 7, the connecting plate, the clamp and the base.

[0051] Secondly, embed the sliding plate 4 in the slide rail 11 to ensure that each sliding plate 4 is embedded between the two blocking blocks 13 in the slide rail 11, and then use expansion bolts to pass through the positioning holes 12 to position the slide rail 11.

[0052] Finally, release the connection between the other end of the upper seat 18 and the other end of the lower seat 17, and flip the upper seat 18 along one end of the upper seat 18. Then, place the embedded pipeline on the lower seat 17 and make the upper seat 18 buckle above the lower seat 17, and realize the connection between the other end of the upper seat 18 and the other end of the lower seat 17. At this time, the fixing process of the embedded pipeline can be completed.
