Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable temporary support for installing a small-diameter pipeline. Background Art

[0002] The installation of small-diameter piping in structures like residential floors and factory buildings inevitably requires large, high-headroom spaces. The installation of small-diameter piping, such as fire sprinkler systems, in ceiling areas requires two gantry platforms and the coordination of appropriate personnel. These two gantry platforms are used to install and support the small-diameter pipes at both ends, but this installation method requires a large number of personnel.

[0003] In the related art, the temporary support for the installation of small-diameter pipes is used to support one end of the small-diameter pipe, and the other end of the small-diameter pipe is installed using a gantry work platform. This method can save the gantry work platform and labor. At present, the temporary support for the installation of small-diameter pipes adjusts the overall height through an adjustable support rod, and supports the pipe through a limiting U-shaped ring set at the top of the adjustable support rod. However, the pipe is restricted by the limiting U-shaped ring. When the pipe encounters movement of the installation end or movement of the adjustable support rod, the pipe is easy to fall off from the limiting U-shaped ring, causing support failure, which is easy to cause damage to the pipeline, and the fallen pipe is also easy to hit the staff.

[0004] How to invent an adjustable temporary support for small-diameter pipeline installation to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0032] Example

[0033] See also Figures 1 to 10 The utility model provides an adjustable temporary support for installing a small-diameter pipeline, including an adjustable support assembly 100 and a locking tube assembly 200. The adjustable support assembly 100 is used to adjust the locking tube assembly 200 to a position to support the pipeline, and the locking tube assembly 200 is used to lock the end of the pipeline that needs to be supported.

[0034] See also Figures 1 to 3 The lock tube assembly 200 includes a support member 210, an external elastic lock tube member 220, a limiting plug-in member 230 and a telescopic limiting lock member 240. The support member 210 is rotatably connected to the top of the adjustable support assembly 100. The external elastic lock tube member 220 is provided in two, and the two external elastic lock tube members 220 are symmetrically arranged at the left and right ends of the upper side of the support member 210. The elastic force on the two external elastic lock tube members 220 can push the upper ends of the two external elastic lock tube members 220 away from each other, the limiting plug-in member 230 and the telescopic limiting lock member 240 are arranged on both sides of the external elastic lock tube member 220, and the limiting plug-in member 230 and the telescopic limiting lock member 240 on the two external elastic lock tube members 220 are correspondingly arranged, and the telescopic limiting lock member 240 on one of the external elastic lock tube members 220 can lock the other limiting plug-in member 230. When in use, the adjustment support assembly 100 is moved to the end of the pipe that needs to be supported, and the pipe falls between the two external spring-lock pipe fittings 220. The pipe presses the limit plug-in 230, and the limit plug-in 230 pushes the two external spring-lock pipe fittings 220 to close together. The limit plug-in 230 pushes the telescopic limit locking piece 240 to elastically expand and contract. After the limit plug-in 230 is inserted into the telescopic limit locking piece 240, the limit plug-in 230 and the telescopic limit locking piece 240 limit and lock each other, thereby locking the two closed external spring-lock pipe fittings 220. The spring-locking pipe fitting 220, the closed outer spring-locking pipe fitting 220 blocks the pipe, reducing the occurrence of the pipe detaching from the two closed outer spring-locking pipe fittings 220, and the support member 210 can be rotated at the top of the adjustable support assembly 100, so that the locking pipe assembly 200 can adapt to the angle of the pipe. The adjustable temporary support for small-diameter pipe installation has the effect of supporting small-diameter pipes and locking the supporting end of the small-diameter pipe, reducing the failure of the small-diameter pipe support, and also reducing the occurrence of personal injury caused by the failure of the small-diameter pipe support.

[0035] See also Figures 1 to 4 The adjustable support assembly 100 includes a fixed support member 110, a compression lock member 120, an adjustment tube 130, and an unlocking limit frame 140. The compression lock member 120 is disposed at the upper end of the fixed support member 110, and the lower end of the adjustment tube 130 is slidably inserted into the fixed support member 110. The compression lock member 120 can compress and lock the adjustment tube 130. The unlocking limit frame 140 is fixedly connected to the outer wall of the upper end of the adjustment tube 130. The unlocking limit frame 140 can push the telescopic limit lock member 240 to release the lock of the telescopic limit lock member 240 on the limit plug-in member 230. When adjusting the height of the locking tube assembly 200, the locking of the adjusting tube 130 by the compression lock member 120 is released, and the adjustment tube 130 is extended and retracted along the fixed support member 110. The position of the top end of the adjustment tube 130 changes as the adjustment tube 130 is extended and retracted, allowing the locking tube assembly 200 to support the pipeline. Thereafter, the compression lock member 120 is used to lock the adjustment tube 130.

[0036] See also Figures 1 to 5 The support member 210 includes a support base 211 and an ear base 212. The support base 211 is rotatably connected to the top of the adjustment tube 130. Four ear bases 212 are provided, and the four ear bases 212 are symmetrically fixedly connected to the left and right ends of the upper side of the support base 211. The external spring-lock pipe 220 is rotatably connected to the two ear bases 212 at the same end. The support base 211 is used to support the external spring-lock pipe 220, and the ear base 212 is used to connect to the external spring-lock pipe 220.

[0037] See also Figures 1 to 6 The adjusting tube 130 includes a first tube body 131 and a first limiting ring 132. The first limiting ring 132 is fixedly connected to the inside of the upper end of the first tube body 131. The bearing 150 is fixedly inserted in the upper end of the first tube body 131. The first limiting ring 132 limits the lower side of the outer ring of the bearing 150. The support seat 211 includes a seat plate 2111, a top ring 2112, a rotating shaft 2113 and a retaining ring 2114. The top ring 2112 and the retaining ring 2114 are both fixedly connected to the lower side of the seat plate 2111. The rotating shaft 2113 is fixedly connected to the lower side of the top ring 2112. The rotating shaft 2113 is fixedly inserted into the inner ring of the bearing 150. The top ring 2112 presses the upper side of the inner ring of the bearing 150, and the retaining ring 2114 is sleeved on the outside of the top end of the retaining ring 2114. The rotating shaft 2113 of the seat plate 2111 is rotatably connected to the top of the first tube body 131 through the bearing 150, and the outer ring and inner ring of the bearing 150 are limited by the first limiting ring 132 and the top ring 2112. The retaining ring 2114 blocks the gap between the seat plate 2111 and the first tube body 131, making it convenient for the seat plate 2111 and the components on the seat plate 2111 to rotate, so that the pipeline can fall between the two external spring-locking pipe fittings 220.

[0038] See also Figures 1 to 7The external spring lock pipe fitting 220 includes a rotating seat 221, an arc-shaped lock tube plate 222, a connecting shaft 223, a mounting plate 224 and a torsion spring 225. The rotating seat 221 and the torsion spring 225 are each provided with two, and the two rotating seats 221 are fixedly connected to the two sides of the lower end of the arc-shaped lock tube plate 222, and the connecting shaft 223 is fixedly connected between the two rotating seats 221. The connecting shaft 223 is rotatably connected to the two ear seats 212 at the same end, and the mounting plate 224 is fixedly sleeved on the connecting shaft 223. The two torsion springs 225 are both sleeved on the connecting shaft 223. The opposite ends of the two torsion springs 225 are fixed to the mounting plates 224, and the opposite ends of the two torsion springs 225 are respectively fixed to the two ear seats 212. The pre-tightening force of the torsion spring 225 can push the arc-shaped lock tube plate 222 to swing outward. When the limit connector 230 and the telescopic limit locking member 240 are not locked, the elastic force of the torsion spring 225 pushes the mounting plate 224 to rotate, and the mounting plate 224 drives the connecting shaft 223 to rotate, and the rotating seat 221 and the arc-shaped lock tube plate 222 swing outward with the connecting shaft 223 (that is, the direction in which the upper ends of the two arc-shaped lock tube plates 222 move away from each other). When the pipeline presses the limit connector 230, the gravity of the pipeline pushes the limit connector 230 to swing, and the limit connector 230 drives the rotating seat 221 and the arc-shaped lock tube plate 222 to swing inward. The two arc-shaped lock tube plates 222 close together to lock the position of the pipeline, reducing the falling off of the pipeline. The connecting shaft 223 and the mounting plate 224 rotate with the rotating seat 221, and the mounting plate 224 drives the torsion spring 225 to twist, and the elastic force of the torsion spring 225 increases. A limiting block 226 is provided on the outer side of the rotating seat 221 , and the upper side of the supporting seat 211 can block the limiting block 226 , thereby limiting the outward swing angle of the arc-shaped locking tube plate 222 .

[0039] See also Figures 1 to 8The limiting connector 230 includes a fixed block 231 and a plug-in limiting rod 232. The fixed block 231 is fixedly connected to one side of the outer spring lock pipe 220, and the plug-in limiting rod 232 is fixedly connected to the fixed block 231. The telescopic limiting locking member 240 includes a mounting block 241, a locking block 242, a prismatic sliding rod 244, a baffle 245, a compression spring 246 and a stretching rod 247. The mounting block 241 is fixedly connected to the other side of the outer spring lock pipe 220. The mounting blocks 241 and the fixed blocks 231 on the two outer spring lock pipes 220 correspond to each other. A mounting groove is provided inside the mounting block 241 near one end of the fixed block 231. The prismatic sliding rod 244 is fixedly connected to one end of the locking block 242. The other end of the locking block 242 is provided with a sloped surface. A plug-in hole 243 is provided on the slope surface of the fixed block 242, and the plug-in limit rod 232 can be inserted into the plug-in hole 243. The prismatic slide bar 244 passes through the mounting groove and then slides through the locking block 242. The baffle 245 is fixedly connected to the prismatic slide bar 244 and extends out of one end of the locking block 242. The compression spring 246 is sleeved on the prismatic slide bar 244. The compression spring 246 is located in the mounting groove. One end of the compression spring 246 presses the inner wall of the mounting groove, and the other end of the compression spring 246 presses the locking block 242. The stretching rod 247 is fixedly connected to the baffle 245 away from one end of the prismatic slide bar 244. As the unlocking limit frame 140 rotates, the unlocking limit frame 140 blocks the stretching rod 247, and the prismatic slide bar 244 can slide along the mounting block 241. When the pipe is inserted between the two external spring lock pipe fittings 220, the pipe presses the plug-in limit rods 232 on the two external spring lock pipe fittings 220, and the plug-in limit rods 232 drive the two external spring lock pipe fittings 220 to close each other. As the two external spring lock pipe fittings 220 close, the plug-in limit rods 232 first contact the slope surface of the corresponding locking block 242, and the locking block 242 is pushed by the plug-in limit rods 232. The locking block 242 drives the prismatic slide bar 244 along the installation block 2 41 slides, the compression spring 246 is compressed, and the elastic force of the compression spring 246 increases. When the end of the plug-in limit rod 232 corresponds to the plug-in hole 243, under the elastic force of the compression spring 246, the plug-in limit rod 232 is inserted into the plug-in hole 243, and the angles of the locking block 242 and the plug-in limit rod 232 are locked with each other, thereby locking the two closed external spring-locking pipe fittings 220. The upper end of the closed external spring-locking pipe fitting 220 blocks the pipeline, reducing the detachment of the pipeline.After the pipeline is installed, the adjusting tube 130 is rotated, and the adjusting tube 130 drives the unlocking limit frame 140 to gradually approach the stretching rod 247. Since the angle of the external spring-locking pipe 220 is limited by the pipeline, the unlocking limit frame 140 pushes the stretching rod 247, and the stretching rod 247 pulls the baffle 245. The baffle 245 pulls the prismatic sliding bar 244 to slide along the installation block 241, so that the locking block 242 is separated from the plug-in limit rod 232. At this time, the adjusting tube 130 is lowered to allow the pipeline to be aligned with the plug-in When the locking rod 232 is released from its compression, the locking block 242 and the plug-in limiting rod 232 begin to swing under the elastic force of the external spring-locking pipe 220, causing them to become misaligned. At this point, the rotation of the adjustment tube 130 is released, and the locking block 242 and the plug-in limiting rod 232 continue to move apart under the elastic force of the external spring-locking pipe 220. The two external spring-locking pipes 220 open apart, thereby releasing the pipe. The unlocking limiting frame 140 includes a mounting seat 141 and a limiting plate 142. The mounting seat 141 is fixedly connected to the outer wall of the adjustment tube 130, and the limiting plate 142 is fixedly connected to the outer end of the mounting seat 141. The limiting plate 142 is capable of blocking the stretching rod 247. The mounting seat 141 supports the limiting plate 142, which is used to block and push the stretching rod 247.

[0040] See also Figures 1 to 9 The compression lock member 120 includes an internally threaded barrel 121 and a compression bolt 122. The internally threaded barrel 121 is fixedly inserted through the outer wall of the upper end of the fixed support member 110. The compression bolt 122 is threadedly connected to the internally threaded barrel 121. The compression bolt 122 can compress the outer wall of the adjustment tube 130. When locking the adjustment tube 130, the compression bolt 122 is rotated. As the compression bolt 122 is screwed into the internally threaded barrel 121, the end of the compression bolt 122 gradually compresses the outer wall of the adjustment tube 130, thereby locking the adjustment tube 130.

[0041] See also Figures 1 to 10The fixed support member 110 includes a movable frame 111 and a support tube 112. The lower end of the support tube 112 is fixedly inserted into the movable frame 111. The adjusting tube 130 is slidably inserted into the upper end of the support tube 112. The pressing and locking member 120 locks the adjusting tube 130. The movable frame 111 includes a seat tube 1111, a fixing portion 1112, a support leg 1113 and a universal wheel 1114. The support leg 1113 is provided in plurality, and the plurality of support legs 1113 are evenly and obliquely arranged on the outer wall of the seat tube 1111. The universal wheel 1114 is fixedly connected to the bottom end of the support leg 1113. The fixing portion 1112 is evenly spaced and arranged at the upper end of the seat tube 1111. The fixing portion 1112 and the pressing and locking member 120 have the same structure. The support tube 112 is inserted into the seat tube 1111, and the fixing portion 1112 presses and locks the support tube 112. The bottom end of the seat tube 1111 is closed to support the support tube 112, and then the support tube 112 is locked by the fixing part 1112. The support legs 1113 are used to support the seat tube 1111, the support tube 112 and the adjustment tube 130, and the universal wheel 1114 facilitates the movement of the entire support.

[0042] Specifically, the working principle of the adjustable temporary support for small-diameter pipeline installation is as follows: when the pipeline is inserted between the two external spring-lock pipe fittings 220, the pipeline presses the plug-in limit rods 232 on the two arc-shaped lock tube plates 222, and the plug-in limit rods 232 drive the two arc-shaped lock tube plates 222 to swing inward and close together, and the connecting shaft 223 and the mounting plate 224 rotate with the rotating seat 221, and the mounting plate 224 drives the torsion spring 225 to twist, and the elastic force of the torsion spring 225 increases. As the two arc-shaped lock tube plates 222 close, the plug-in limit rod 232 first contacts the slope surface of the corresponding locking block 242, and the locking block 242 is pushed by the plug-in limit rod 232, and the locking block 242 drives the prismatic slide bar 244 along the installation The block 241 slides, the compression spring 246 is compressed, and the elastic force of the compression spring 246 increases. When the end of the plug-in limit rod 232 corresponds to the plug-in hole 243, under the elastic force of the compression spring 246, the plug-in limit rod 232 is inserted into the plug-in hole 243, and the angles of the locking block 242 and the plug-in limit rod 232 are locked with each other, thereby locking the two closed arc-shaped locking tube plates 222. The upper ends of the closed arc-shaped locking tube plates 222 block the pipeline, reducing the falling off of the pipeline, so that the adjustable temporary support for small-diameter pipeline installation has the effect of supporting small-diameter pipelines and locking the supporting end of small-diameter pipelines, reducing the failure of small-diameter pipeline supports, and also reducing the occurrence of personal injuries caused by failure of small-diameter pipeline supports.

[0043] After the pipeline is installed, the adjusting tube 130 is rotated, and the adjusting tube 130 drives the unlocking limit frame 140 to gradually approach the stretching rod 247. Since the angle of the arc-shaped locking tube plate 222 is limited by the pipeline, the unlocking limit frame 140 pushes the stretching rod 247, and the stretching rod 247 pulls the baffle 245. The baffle 245 pulls the prismatic sliding bar 244 to slide along the installation block 241, so that the locking block 242 is disengaged from the plug-in limit rod 232. At this time, the adjusting tube 130 is lowered so that the pipeline is aligned with the plug-in limit rod. When the pressure of 232 is released, the locking block 242 and the plug-in limit rod 232 produce a moving swing under the elastic force of the external spring-locking pipe 220, so that the locking block 242 and the plug-in limit rod 232 are inconsistently connected. At this time, the rotation of the regulating tube 130 is relaxed, and the locking block 242 and the plug-in limit rod 232 will continue to move away from each other as the rotating seat 221 rotates under the elastic force of the torsion spring 225, and the two arc-shaped locking tube plates 222 open to each other, thereby achieving the purpose of releasing the pipeline.
