Description

Technical Field

[0001] This utility model relates to the field of spring support and hanger technology, and in particular to a limit-type variable spring support and hanger. Background Technology

[0002] Thermal pipelines with large thermal deformation are suitable for using elastic supports with strong compensation capabilities. Spring supports are a typical elastic support structure. Before commissioning, the compression spring plates in the spring supports are limited by pins located on both sides of the cylinder. After setting the load, pulling out the pins can achieve elastic support. Variable spring supports, while ensuring displacement, prevent the pipeline from moving upward or downward beyond its range, thereby ensuring the normal operation of the pipeline.

[0003] A search revealed a published (announcement) document (CN216923464U) disclosing a range-extended variable spring support, belonging to the technical field of variable spring supports. The support includes a cylindrical body with a first force transmission tube inserted inside. A first support plate is fixedly connected to the bottom of the first force transmission tube, and a first compression spring is movably sleeved on the outer wall of the first force transmission tube. A range-extending mechanism is provided at the bottom of the first support plate, comprising a second support plate and a second force transmission tube. A through groove is formed at the central axis of the second support plate. This invention improves the support tolerance of the spring support body through the range-extending mechanism, enabling the spring support body to provide elastic support for heavier pipes. Simultaneously, the adjusting mechanism moves the limiting sleeve through the positioning groove and matches the locking hole, thereby limiting and fixing it. The buffer stroke and buffering force of the variable spring support are easily adjustable and adapted, thus achieving the purpose of load adjustment.

[0004] While the above-mentioned solution allows for easy adjustment and adaptation of the buffer stroke and buffer force of the variable spring support, thereby achieving the purpose of load adjustment, its fixed rod structure makes it inconvenient to conveniently adjust the pipe clamp height of the rod according to the on-site installation conditions. Therefore, we propose a limit-type variable spring support. Utility Model Content

[0005] The main purpose of this utility model is to provide a limit-type variable spring support bracket, which solves the problem that the pipe clamp height of the support rod is inconvenient to adjust according to the on-site installation conditions due to the fixed structure of the support rod.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A limit-type variable spring support includes a main unit, a suspension unit disposed inside the main unit, a fixing unit disposed below the suspension unit, and an adjustment unit disposed between the suspension unit and the fixing unit.

[0008] The suspension unit includes a movable disk movably disposed inside the main unit, a first spring installed between the top wall of the main unit and the movable disk, a second spring disposed between the movable disk and the bottom wall of the main unit, a first threaded groove opened on the side wall of the movable disk, a threaded through hole opened on the side wall of the main unit, and a threaded post movably penetrating through and placed inside the threaded through hole.

[0009] The adjustment unit includes a rotating groove inside the movable disk, a rotating disk movably disposed inside the rotating groove, a suspension rod installed at the bottom of the rotating disk, and an adjustment component disposed below the suspension rod.

[0010] Preferably, the main body unit includes a cylindrical body and a mounting base installed on the top of the cylindrical body.

[0011] Preferably, the main body unit further includes a second threaded groove formed at the bottom of the cylinder, a limiting threaded rod that is movably inserted through and disposed in the second threaded groove, and a screwing handle installed at the bottom of the limiting threaded rod.

[0012] Preferably, the adjusting component includes a threaded cylinder mounted on the top of the fixed unit, and an adjusting threaded rod mounted on the bottom of the suspension rod and movably disposed inside the threaded cylinder.

[0013] Preferably, the fixing unit includes an upper arc-shaped clamping plate disposed below the cylinder, a lower arc-shaped clamping plate movably mounted below the upper arc-shaped clamping plate, and fasteners disposed between the upper arc-shaped clamping plate and the lower arc-shaped clamping plate.

[0014] Preferably, the fastener includes an upper connecting plate mounted on the side wall of the upper arc-shaped clamping plate, a lower connecting plate mounted on the side wall of the lower arc-shaped clamping plate, fastening through holes formed on the upper and lower connecting plates, a screw rod that movably passes through the fastening through holes, and a nut mounted on the circumferential side of the screw rod.

[0015] Preferably, the fixing unit further includes an arc-shaped rubber pad installed on the inner sidewalls of the upper arc-shaped clamping plate and the lower arc-shaped clamping plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, by setting up a suspension unit and an adjustment unit, when it is necessary to adjust the height of the pipe clamp according to the on-site installation conditions, the adjusting threaded rod can be rotated to make the adjusting threaded rod move spirally in the threaded cylinder, thereby changing the distance between the cylinder and the fixed unit to adapt to different pipe heights and improve applicability. When it is necessary to support the pipe, after the pipe passes through the upper arc-shaped clamping plate and the lower arc-shaped clamping plate, the screw rod passes through the fastening through hole of the upper connecting plate and the lower connecting plate, and then the nut is tightened on the screw rod to achieve fixed clamping of the pipe. By turning the screw handle, the limiting threaded rod can be inserted into the cylinder, thereby adjusting and limiting the up and down movement of the moving plate. Attached Figure Description
