Description

Technical Field

[0001] This utility model belongs to the field of communication pipeline technology, and in particular relates to an adjustable pipeline support and positioning bracket for laying communication pipelines. Background Technology

[0002] With the rapid development of urban informatization, the scale of communication pipeline installation is expanding daily. As carriers of optical cables, electrical cables, and other cables, they face higher requirements for the reliability of fixation and protection. During the installation of communication pipelines, they typically need to be fixed to walls, cable trays, or supports in integrated pipe galleries to prevent displacement or deformation due to their own weight, thermal expansion and contraction, or external vibrations, thereby ensuring the safety and stability of communication lines. Currently, the most common pipeline fixing device is a clamp structure formed by two symmetrical semi-circular clamps fastened with bolts. This structure provides effective fixation for standard pipelines whose inner diameter perfectly matches the clamps.

[0003] However, this traditional clamp structure cannot accommodate pipes with different outer diameters. When the outer diameter of the pipe being clamped does not match the inner diameter of the clamp, a gap will exist between the pipe and the inner wall of the clamp, resulting in only local point contact or line contact between the clamp and the pipe after tightening (e.g., Figure 8 As shown, a represents a matching specification, and b represents a mismatched specification), rather than an ideal surface contact. This concentrated contact method prevents the clamping force from being evenly distributed, resulting in excessive pressure per unit area of ​​the pipe. Over time, this can easily cause localized pressure damage or even rupture of the pipe wall. This point-contact stress concentration is particularly dangerous in communication pipes using brittle materials (such as PVC and CPVC), becoming a safety hazard in the long-term operation of the pipe.

[0004] To address these issues, we propose an adjustable pipe support and positioning bracket for communication pipeline laying. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the clamping force cannot be evenly distributed for pipes with different outer diameter specifications, and to propose an adjustable pipe support and positioning bracket for laying communication pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable pipe support and positioning bracket for laying communication ducts, comprising:

[0008] Two sets of clamping assemblies are symmetrically arranged with their openings facing each other, together forming a clamping space for holding the pipe. Multiple mounting cavities are evenly distributed circumferentially on the inner side of each clamping assembly, and radially extending connecting lugs are provided at both ends of each clamping assembly.

[0009] A connecting structure for connecting corresponding connecting lugs of two sets of clamp assemblies;

[0010] Multiple clamping units are distributed circumferentially inside the clamping assembly. Each clamping unit includes a clamping member slidably disposed in the mounting cavity and an elastic element that drives the clamping member to move toward the clamping center.

[0011] A locking mechanism, located inside the clamp assembly, is used to simultaneously lock the radial positions of multiple clamping units;

[0012] A mounting bracket is provided on the outside of any clamp assembly, and the mounting bracket has mounting holes for fixing to an external support.

[0013] Preferably, the connection structure includes a through hole disposed on the connecting lug plate and a fastener passing through the through hole.

[0014] Preferably, the clamping member includes a columnar body and a buffer pad disposed at its clamping end.

[0015] Preferably, the clamping member has a radially protruding anti-detachment part at one end located in the mounting cavity, and the opening of the mounting cavity has a limiting and closing part that cooperates with the anti-detachment part.

[0016] Preferably, the locking mechanism includes a locking frame that is axially movable within the clamping assembly. The locking frame has a plurality of semi-circular notches that cooperate with the clamping member. The inner wall of the notch is provided with a first tooth structure, and the side wall of the clamping member is provided with a corresponding second tooth structure.

[0017] Preferably, the locking frame extends connecting ear plates at both ends and is provided with wedge blocks. The wedge blocks are adapted to wedge grooves provided on the connecting ear plates of another clamp assembly. When the two clamp assemblies are closed, the interaction between the wedge blocks and the wedge grooves drives the locking frame to move, so that the notch engages with the clamping member.

[0018] Preferably, the clamping unit further includes a guide post fixedly disposed in the mounting cavity, the guide post extending into the clamping member.

[0019] In summary, the technical effects and advantages of this utility model are as follows: This adjustable pipe support and positioning bracket for communication pipeline laying uses multiple radial clamping members driven by elastic elements on the inner side of the clamp assembly. During the locking process, these clamping members can independently extend and retract radially, ensuring that the buffer pads at their ends always remain in contact with the outer wall of the pipe. Applicable to pipes of different specifications, all clamping members can adaptively adjust under the action of springs, collectively forming a "multi-point support surface" that matches the outer contour of the pipe. This disperses the concentrated point contact force of traditional clamps into a distributed force borne by multiple contact points, reducing the pressure per unit area of ​​the pipe wall and fundamentally avoiding pipe pressure damage and destruction caused by stress concentration.

[0020] The communication pipeline is laid using an adjustable pipeline support and positioning bracket, which is equipped with a locking mechanism that is linked to the closing action of the clamping ring. In the initial stage of clamping assembly closure, the clamping unit is in a dynamic adaptive state and can be freely adjusted to adapt to the pipeline. When the clamping assembly is further closed and tightened through the connecting structure, the locking frame moves, so that the notch engages with the clamping member, locking multiple independent clamping members synchronously and rigidly in their current position. This allows the entire device to seamlessly transition from a dynamic adaptive state to a static rigid locking state. The clamping ring closure and clamping unit locking are achieved simultaneously through a single tightening action, making the operation simple and efficient. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Reference Figure 1-7 An adjustable pipe support and positioning bracket for laying communication pipelines is proposed. Its core is to achieve stable and non-destructive fixing of pipes of different specifications through an adaptive clamping and linkage locking mechanism. It includes two sets of clamping assemblies 1, a connecting structure 4, multiple clamping units 5, a locking mechanism 6, and a mounting bracket 2.

[0032] The clamp assembly 1 has a semi-circular arc structure, and both ends of the clamp assembly 1 are provided with radially extending connecting ear plates 3. The two clamp assemblies 1 are symmetrically arranged and their openings face each other. After being connected by the connecting ear plates 3 at both ends, they together form a circular clamping space for clamping the communication pipe. Multiple mounting cavities are evenly distributed along the circumference on the inner side of the clamp assembly 1, providing space for the clamping unit 5 to be accommodated and moved.

[0033] Reference Figure 3 The connecting structure 4 is used to connect the corresponding connecting ear plates 3 of the two sets of clamping assemblies 1. The connecting structure 4 includes a through hole 41 on the connecting ear plate 3 and a fastener 42 passing through the through hole 41. In this embodiment, the fastener 42 is a bolt and a nut. Tightening the bolt and nut can drive the two clamping assemblies 1 to close, forming a clamping force on the pipe.

[0034] Reference Figure 2-7The clamping unit 5 is a key component for achieving adaptive clamping. Multiple clamping units 5 are distributed circumferentially inside the clamping assembly 1. Each clamping unit 5 includes a clamping element 51, an elastic element 52, and a guide post 53. The clamping element 51 is slidably disposed within the mounting cavity. A buffer pad 511 made of rubber or soft plastic is provided on the side facing the pipe (clamping end), which effectively increases friction and prevents hard contact from scratching the pipe surface. One end of the clamping element 51 located within the mounting cavity has a radially protruding anti-detachment part 512, while the opening of the mounting cavity has a limiting constriction. The anti-detachment part 512 and... The limiting and closing mechanism ensures that the clamping member 51 will not be completely pushed out of the mounting cavity when it extends outward under the push of the elastic element 52, thus preventing it from falling off. The guide post 53 is coaxially fixed in the mounting cavity and extends into a blind hole inside the clamping member 51. The elastic element 52 is a compression spring located in the blind hole inside the clamping member 51. One end of the spring abuts against the guide post 53, and the other end abuts against the inside of the clamping member 51. In its natural state, the elastic force of the elastic element 52 drives the clamping member 51 to always have a tendency to move towards the center of contact, so that its buffer pad 511 can be pressed against the outer wall of the pipe.

[0035] The locking mechanism 6 is designed to lock the position of the clamping unit 5 after it has been adaptively adjusted to the correct position, preventing it from retracting due to vibration or other reasons during use and ensuring long-term stability of the fixed position.

[0036] Reference Figure 2-7 The locking mechanism 6 includes a locking frame 61 slidably disposed axially (i.e., parallel to the pipe axis) within the cavity of the clamp assembly 1. The locking frame 61 has multiple semi-circular notches 62 corresponding to the number and position of the clamping members 51. Each notch 62 has a first toothed structure 621 machined into its inner wall. Correspondingly, each clamping member 51 has a second toothed structure 513 adapted to the first toothed structure 621 machined into its columnar body sidewall. Connecting ear plates 3 of the clamp assembly 1 extend from both ends of the locking frame 61, and wedge blocks 63 are fixedly disposed at the ends. These wedge blocks 63 are adapted to wedge grooves 31 formed on the connecting ear plates 3 of another clamp assembly 1.

[0037] When the clip is fastened onto the pipe and the fastener 42 is tightened, the two clamping assemblies 1 gradually move closer together. During this process, each clamping member 51 independently expands and contracts radially under the action of the elastic element 52, so that its buffer pad 511 fits tightly against the outer wall of the pipe, achieving adaptive coverage. As the clamping assembly 1 closes, the wedge block 63 on one clamping assembly 1 will insert into the wedge groove 31 of the other clamping assembly 1. Due to the interaction of the wedge surfaces, the wedge block 63 will be subjected to a lateral thrust during insertion. This thrust drives the entire locking frame 61 to slide axially within the clamping assembly 1. The movement of the locking frame 61 causes its semi-circular notch 62 to engage with the clamping member 51. Finally, the first tooth structure 621 in the notch 62 and the second tooth structure 513 on the side wall of the clamping member 51 are tightly engaged, so that the clamping members 51 are simultaneously limited and locked, and the radial positions of the clamping members 51 are synchronously and rigidly locked, thus completing the transition from dynamic adaptive to static stable locking.

[0038] An installation bracket 2 is fixedly installed on the outer wall of one of the clamp components 1. The installation bracket 2 has at least one installation hole 21. By passing bolts, nails or other fixing methods through the installation hole 21, the entire buckle can be firmly installed on the wall, cable tray or other support, thus completing the support and positioning of the entire pipeline.
