Description

Technical Field

[0001] This utility model relates to the field of thermal engineering technology, specifically to a steam pipeline fixing device for thermal engineering. Background Technology

[0002] Steam pipelines, also known as heating networks, are networks formed by multiple heating pipelines. To address the problem of pipelines being unable to be fixed due to the embedded steel plates on the supports not being horizontal and tilting in a certain direction during actual construction, related devices have emerged.

[0003] For example, Chinese utility model patent CN217153276U, entitled "A Universal Support for Fixing Large-Diameter High-Temperature Steam Pipelines," describes a universal support placed on a concrete pier. The universal support consists of a lower support and an upper support. The upper support is rotatably mounted on the lower support via a pivot. After rotating around the pivot in the axial direction of the high-temperature steam pipeline, the upper support is fixedly connected to the lower support. The lower support has a base plate and a lower support plate. The base plate is placed flush against the upper surface of the concrete pier, and the lower support plate is vertically fixed to the upper surface of the base plate. The upper support has an upper support plate and a clamp. The lower end of the upper support plate is rotatably connected to the upper end of the lower support plate, and the clamp is fixed to the upper end of the upper support plate. This device allows for slight rotation between the upper and lower supports in the horizontal normal direction around the axis of the steam pipeline, ensuring full contact between the lower support base plate and the upper surface of the concrete pier. This minimizes the sliding friction resistance between the high-temperature steam pipeline support and the concrete pier, thereby ensuring the stability of the pipeline. During the installation of steam pipes, workers first need to support the two steam pipes with their ends touching using brackets, then align the two pipes with their axes aligned, and finally weld the touching ends of the two steam pipes together.

[0004] However, if workers align the two steam pipes on the support by hand and visual inspection during installation, the coaxiality of the steam pipes will be poor, and even a small deviation between adjacent steam pipes will seriously affect the welding quality of the steam pipes. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a steam pipe fixing device for thermal engineering, which solves the technical problem that the welding quality of the two steam pipes is poor because the two pipes are aligned on the support by workers using their hands and visual observation during installation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problem of poor weld quality in the two steam pipes when aligned on a support by workers using only their hands and visual inspection during installation, this invention provides a steam pipe fixing device for thermal engineering. This device uses two spaced-apart clamping members 210 on a base 300 that can slide close to or away from each other to clamp and connect the two steam pipes. The two steam pipes align when brought close together, ensuring coaxiality and preventing small deviations between adjacent pipes from affecting the welding quality. The device is simple in structure and easy to operate.

[0028] Please see Figures 1 to 4 , Figure 1 , Figure 2This is a schematic diagram of the structure of a steam pipe fixing device for thermal engineering in one embodiment of the present invention. The steam pipe fixing device for thermal engineering is used to connect two steam pipes and includes: a mounting base 100 and two clamping components 200. The clamping components 200 include clamping members 210, sliding members 220 and snap-fit ​​members 230. The clamping members 210 have a clamping gap 211 for clamping the steam pipe. The two sliding members 220 are respectively connected to the two clamping members 210 and are slidably connected to the mounting base 100. The two sliding members 220 can respectively drive the two steam pipes to move closer or further away from each other. The snap-fit ​​member 230 is connected to the sliding member 220 and can snap-fit ​​with the mounting base 100 to limit the sliding of the sliding member 220, the clamping member 210 and the steam pipe relative to the mounting base 100.

[0029] In this device, two clamping members 210 are arranged at intervals on the mounting base 100. The two clamping members 210 each have two clamping gaps 211 for clamping the steam pipe. The two clamping members 210 are slidably connected to the mounting base 100 via two sliding members 220. The snap-fit ​​member 230 is connected to the sliding member 220 and can snap-fit ​​with the mounting base 100 to limit the sliding member 220, the clamping member 210 and the steam pipe from sliding relative to the mounting base 100.

[0030] Furthermore, by setting two spaced-apart clamping members 210 on the base 300 that can slide close to or away from each other, the two steam pipes are clamped and connected respectively. The two steam pipes can be aligned after they come close to each other, thereby ensuring the coaxiality of the two steam pipes after alignment. This avoids the small displacement of adjacent steam pipes from affecting the welding quality of the steam pipes. The structure is simple and easy to operate. It can solve the technical problem in the prior art that the two steam pipes are aligned on the support by workers using their hands and visual observation during installation, which leads to poor welding quality of the two steam pipes.

[0031] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the mounting base 100 has a sliding groove, and the sliding member 220 includes a sliding block 221. One end of the sliding block 221 is slidably built into the sliding groove, and the other end is connected to the clamping member 210.

[0032] The slide groove and the sliding block 221 cooperate to realize the sliding connection between the sliding block 221 and the mounting base 100.

[0033] In one embodiment, please refer to Figure 3 , Figure 4The inner wall of the slide groove is also provided with at least one guide groove along the guide of the slide groove. The guide groove is connected to the slide groove. The sliding member 220 also includes at least one guide block 222. One end of the guide block 222 is slidably embedded in the guide groove and the other end is connected to the sliding block 221.

[0034] Two guide blocks 222 are respectively disposed on both sides of the two sliding blocks 221 to guide the sliding blocks 221 relative to the slide groove and to improve the stability of the sliding blocks 221 relative to the slide groove.

[0035] In one embodiment, please refer to Figure 3 , Figure 4 The snap-fit ​​component 230 includes a rack 231, a rotating gear 232, a first rotating shaft 233, and at least one first locking block 234. The rack 231 is connected to the bottom inner wall of the slide groove. The rotating gear 232 is rotatably connected to the sliding block 221 via the first rotating shaft 233 and meshes with the rack 231. The first locking block 234 is connected to the first rotating shaft 233 and is detachably connected to the sliding block 221, and is used to restrict the rotation of the first rotating shaft 233 and the rotating gear 232 relative to the sliding block 221.

[0036] When the sliding block 221 slides relative to the groove, the rotating gear 232 can mesh with the gear, causing the rotating shaft to rotate relative to the sliding block 221.

[0037] Furthermore, after the first locking block 234 and the sliding block 221 are detachably connected, the rotating shaft cannot continue to rotate relative to the sliding block 221. Therefore, the sliding block 221 cannot slide relative to the mounting base 100, thereby realizing the relative sliding of the two steam pipes.

[0038] In one embodiment, please refer to Figure 3 The sliding block 221 has a receiving groove relative to the rack 231. The rotating gear 232 is rotatably housed in the receiving groove. The two ends of the first rotating shaft 233 are respectively externally placed on the sliding block 221, and the two ends of the first rotating shaft 233 are respectively provided with external threads. The first locking block 234 has a first threaded hole. The first locking block 234 is threadedly connected to the end of the first rotating shaft 233 and abuts against the sliding block 221.

[0039] The first locking block 234 is pressed against the outer wall of the sliding block 221 by means of a threaded connection.

[0040] Furthermore, the first locking block 234 can also be detachably connected to the sliding block 221 by means of elastic snap-fit. For example, a slot is provided on the outer wall of the first rotating shaft 233, and an elastic snap-fit ​​structure is connected to the outer wall of the sliding block 221. When it is necessary to restrict the rotation of the rotating shaft relative to the sliding block 221, the elastic snap-fit ​​structure is engaged in the slot. This will not be elaborated further here.

[0041] In this embodiment, as Figure 1 , Figure 2 As shown, the clamping member 210 includes a lower clamping block 212, an upper clamping block 213, at least two fastening connection parts 214, and a plurality of elastic abutment parts 215. The lower clamping block 212 is connected to the sliding block 221. The upper clamping block 213 is detachably connected to the lower clamping block 212 via at least two fastening connection parts 214. The upper clamping block 213 and the lower clamping block 212 together form a clamping gap 211. The plurality of elastic abutment parts 215 are built into the clamping gap 211 and all abut against the circumferential outer wall of the steam pipe. The plurality of elastic abutment parts 215 are slidably connected to the upper clamping block 213 and the lower clamping block 212 respectively.

[0042] At least two fastening connections 214 can be used to achieve a detachable connection between the upper clamping block 213 and the lower clamping block 212, thereby forming a clamping of the steam pipe.

[0043] Furthermore, the elastic abutment part 215 is built into the clamping gap 211 and can move relative to the upper clamping block 213 and the lower clamping block 212, thereby adapting to steam pipes of different diameters.

[0044] In some embodiments, the elastic abutment part 215 includes a guide rod, a spring, and an arc-shaped abutment block. The arc-shaped abutment block is slidably connected to the upper clamping block 213 or the lower clamping block 212 along the radial direction of the clamping gap 211 via the guide rod, and the inner arc of the arc-shaped abutment block can abut against the outer wall of the steam pipe. The spring is sleeved on the guide rod and is connected to both the arc-shaped abutment block and the upper clamping block 213 or the lower clamping block 212. Further details are omitted here.

[0045] In this embodiment, as Figure 2 , Figure 3 As shown, the clamping assembly 200 also includes a rotating member 240, which includes a first connecting seat 241, a second connecting seat 242, and a locking part 243. The first connecting seat 241 is connected to the sliding block 221, the second connecting seat 242 is connected to the lower clamping block 212, and can rotate relative to the first connecting seat 241. The locking part 243 is connected to the second connecting seat 242 and can engage with the first connecting seat 241 to restrict the rotation of the second connecting seat 242 and the lower clamping block 212 relative to the first connecting seat 241.

[0046] By setting the first connecting seat 241, the second connecting seat 242 and the locking part 243, the axis of the steam pipe can be tilted relative to the plane where the mounting seat 100 is located, so as to adapt to different installation requirements and increase the coaxiality of the two steam pipes.

[0047] Furthermore, the locking part 243 includes at least one second rotating shaft and at least one second locking block. One end of the second rotating shaft is fixedly connected to the second connecting seat 242, and the other end is rotatably connected to the first connecting seat 241. The other end of the second rotating shaft is externally placed on the first connecting seat 241. The second locking block is threadedly connected to the other end of the second rotating shaft and abuts against the first connecting seat 241.

[0048] In this embodiment, such as 1 to Figure 3 As shown, the steam pipe fixing device for thermal engineering also includes a base 300, a lifting assembly 400, and multiple fixing pins 500.

[0049] The base 300 is detachably connected to the ground, and the lifting assembly 400 has a fixed end and a telescopic end. The fixed end of the lifting assembly 400 is connected to the base 300, and the telescopic end is connected to the mounting base 100, which is used to drive the mounting base 100 to rise and fall relative to the base 300.

[0050] The mounting base 100 is slidably connected to the base 300 via the lifting component 400, allowing the installation height of the mounting base 100 to be adaptively adjusted to meet the needs of different usage scenarios.

[0051] In one embodiment, please refer to Figure 3 The lifting assembly 400 includes a lifting sleeve 410, a fixing screw 420, and a rotating sleeve 430. The lifting sleeve 410 is connected to the bottom of the mounting base 100. The lifting sleeve 410 has a sliding hole along its axis. One end of the fixing screw 420 is fixedly connected to the base 300, and the other end is slidably inserted into the sliding hole. The rotating sleeve 430 is threaded onto the fixing screw 420 and rotatably connected to the lifting sleeve 410. The rotating sleeve 430 rotates relative to the lifting sleeve 410, which can drive the mounting base 100 to rise and fall relative to the base 300.

[0052] By rotating the rotating sleeve 430, the lifting sleeve 410 can be driven to rise and fall relative to the fixed screw 420. Its structure is similar to that of a ball screw and nut pair, which will not be described in detail here.

[0053] Furthermore, the lifting assembly 400 here can also be a push rod motor, hydraulic cylinder and pneumatic cylinder that are common and readily available on the market. This is a conventional setting known to those skilled in the art, and will not be described in detail here.

[0054] In one embodiment, please refer to Figures 1 to 3 The base 300 has multiple fixing holes, and the fixing pin 500 has a large diameter section and a small diameter section. The small diameter end of the fixing pin 500 passes through the fixing hole and is inserted into the ground, while the large diameter section of the fixing pin 500 abuts against the base 300.

[0055] The fixing pin 500 has a pointed structure, which allows the user to easily insert it into the ground, thereby enabling the base 300 to be installed on the ground.

[0056] Furthermore, the fixing pin 500 here is a common and readily available ground stake on the market. This is a standard setting known to those skilled in the art, and will not be elaborated further here.

[0057] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0058] Two clamping members 210 are spaced apart on the mounting base 100. Each clamping member 210 has two clamping gaps 211 for clamping steam pipes. The two clamping members 210 are slidably connected to the mounting base 100 via two sliding members 220. A snap-fit ​​member 230 is connected to the sliding member 220 and can snap-fit ​​with the mounting base 100 to restrict the sliding member 220, the clamping members 210, and the steam pipes from sliding relative to the mounting base 100. Compared to existing technologies, by providing two spaced-apart clamping members 210 on the base 300 that can slide closer or further apart, two steam pipes are clamped and connected. When the two steam pipes come close together, they can be aligned, ensuring coaxiality after alignment and preventing small deviations between adjacent steam pipes from affecting the welding quality. The structure is simple and easy to operate.

[0059] The specific workflow of this utility model is as follows: First, the user places the two sections of steam pipe to be welded into the clamping gap 211, so that the elastic abutment part 215 abuts against the circumferential outer wall of the steam pipe. At least two fastening connection parts 214 are used to clamp the steam pipe with the lower clamping block 212 and the upper clamping block 213. Then, by sliding two sliding blocks 221 relative to the mounting base 100, the two steam pipes are brought closer to each other. Then, the locking part 243 is used to adjust the relative rotation of the first connecting seat 241 and the second connecting seat 242, so that the two ends of the two steam pipes are aligned and coaxial. Then, the first locking block 234 and the second locking block are locked respectively. At this point, the position of the two steam pipes relative to the mounting base 100 is fixed. Finally, by adjusting the installation height of the mounting base 100 relative to the base 300, butt welding can be performed. This not only makes it convenient for the user to butt two sections of steam pipe, but also ensures coaxial alignment and improves welding quality.

[0060] This device, through the aforementioned structure, can solve the technical problem in the prior art where the poor quality of the butt weld between the two steam pipes is caused by workers aligning them on the support using only their hands and visual observation during installation.

[0061] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
