Description

Technical Field

[0001] This application relates to the field of support devices, and more particularly to an arched support and protection structure for curved road pipes used in municipal heating. Background Technology

[0002] Currently, urban heating systems primarily use heating pipelines to supply heat to residential areas such as apartment buildings. Furthermore, to minimize the impact on surface space, these heating pipelines are mostly buried underground.

[0003] However, sometimes underground heating pipes may conflict with water supply pipes or power lines. In such cases, it is necessary to place the heating pipes on the ground. At the same time, in order to save surface space and allow the roads on the ground to be used normally, external support devices are needed to support the pipes above the ground.

[0004] Currently, the support devices used are mostly steel structure frames. When installing pipes, it is necessary to accurately connect the pipes, which is quite troublesome because the pipes are relatively thick. Summary of the Invention

[0005] To facilitate the connection of heating pipes that need to be placed on the support device, this application provides an arched support and protection structure for curved road pipes used in municipal heating.

[0006] This application provides a technical solution for an arched support and protection structure for curved road pipes used in municipal heating systems, as follows:

[0007] An arched support and protection structure for curved road pipes used in municipal heating includes an arched support frame. Multiple support blocks are slidably connected to the side wall of the support frame, and each support block is connected to multiple grippers that can clamp the pipe when it is placed on the support block.

[0008] By adopting the above technical solution, when multiple pipes need to be installed on the support frame and spliced ​​together, multiple pipe sections are placed sequentially on multiple support blocks. When the pipes are placed on the support blocks, the grippers on the support blocks clamp the pipes placed on the support blocks to fix the relative position between the pipes and the support blocks. Then, the support blocks can be moved to realize the docking process between the pipes. This reduces the large amount of time wasted when the pipes are placed on the support frame and are difficult to move, thus requiring accurate docking of the pipes between the support frames.

[0009] Optionally, each of the support blocks has multiple abutment plates on the side that can abut against the pipe, and each abutment plate has two abutment rods rotatably connected to the side away from the side that can abut against the pipe, which are arranged at a certain angle to each other. Each abutment rod has a top block rotatably connected to the side away from the abutment plate. Each support block is bent into an arc shape, and the top block is located inside the support block and slides around the arc-shaped side wall of the support block. The top block near the end side wall of the support block is fixedly connected to the claw, and the claw can extend and embed into the support block under the action of the top block.

[0010] By adopting the above technical solution, when the pipe is placed on the support block, the pipe squeezes the abutment plate, thereby causing the abutment plate to move. During the movement of the abutment plate, the abutment rod and the top block move. During the movement of the top block connected to the clamp, the clamp extends out of the support block to clamp the pipe, which makes it easier for the staff to fix the relative position between the support block and the pipe.

[0011] Optionally, the two top blocks connected to the same abutment plate are each connected to the same tension spring on opposite sides.

[0012] By adopting the above technical solution, due to the presence of the tension spring, when the pipeline moves away from the support block under the action of external force, the tension spring can drive the two connected top blocks to move towards each other, so that the gripper can move into the support block under the action of the tension spring. This reduces the trouble caused by the gripper obstructing the pipeline when the worker puts the pipeline back onto the support block, making it difficult to place the pipeline onto the support block.

[0013] Optionally, the abutment plates on the same support block are arranged in pairs, and the two abutment plates in the same group, the abutment rod connected to the abutment plates, and the top block are located in the same plane. The opposite sides of the two adjacent top blocks in the same group are connected with pressure springs.

[0014] By adopting the above technical solution, due to the presence of the pressure spring, the pressure spring can limit the relative position between the two sets of top blocks during the process when the top block is not moved by the abutment rod. This reduces the phenomenon that the top block moves under the action of gravity, which would affect the subsequent process of clamping the pipe with the gripper.

[0015] Optionally, multiple support blocks connected to the upper side of the arched support frame are connected to a movable screw for driving the multiple support blocks to move relative to each other, and the movable screw is connected to a drive shaft for driving the movable screw to rotate via a gear, and a drive sprocket is fixedly sleeved on the drive shaft, and a drive chain is meshed on the drive sprocket.

[0016] By adopting the above technical solution, when it is necessary to move the support block located on the upper side of the support frame, the drive chain is rotated, the drive chain drives the drive shaft to rotate, the drive shaft rotates through the gears to drive the drive screw to rotate, and the drive screw drives the connected support block to move during the rotation, thereby realizing the operation of moving the support block and the pipes on the support block by driving the drive chain, which facilitates the process of moving the support block and the pipes on the support block by the staff.

[0017] Optionally, the support frame is fixedly connected with a buckle that can restrict the position of the drive chain.

[0018] By adopting the above technical solution, the presence of the buckle allows the drive chain to be fixed in position, thereby reducing the impact of the drive chain on the road below the support frame when it is not in use.

[0019] Optionally, the support blocks located on the inclined sidewalls of the arched support frame are all driven by sprockets and chains.

[0020] By adopting the above technical solution, the support block located on the inclined side wall of the support frame can be driven by chains and sprockets, thus facilitating the process of moving the support block and the pipes on the support block by the staff.

[0021] Optionally, multiple ladders and maintenance platforms for workers to climb are fixedly connected to the side wall of the support frame.

[0022] By adopting the above technical solution, the presence of ladders and maintenance platforms reduces the inconvenience of workers having to carry climbing tools when climbing to the top of the support frame to inspect the pipeline.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The presence of the support block allows the pipes to be moved when they need to be spliced ​​together and placed on the support frame. The support block can also clamp the pipes, making the pipe splicing process easier for workers.

[0025] 2. The moving screw drives multiple support blocks located on the upper side of the support frame to move, and the chain and sprocket drive the support blocks located on the side wall of the support frame to move, which facilitates the process of moving the support blocks by the staff.

[0026] 3. By installing ladders and inspection platforms on the support frame, it is convenient for staff to climb to the top of the support frame to inspect the pipeline. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0033] This application discloses an arched support and protection structure for curved road pipes used in municipal heating systems, with reference to... Figure 1 The system includes a support frame 1, which is trapezoidal in shape and consists only of two inclined sides and a horizontal upper base. Each inclined side of the support frame 1 is connected to a support block 2, and two identical support blocks 2 are connected to the upper base. The side of each support block 2 furthest from the adjacent sidewall of the support frame 1 is rounded, and the centerline of the rounded sidewall of each support block 2 is parallel to the length of the adjacent sidewall of the support frame 1.

[0034] Each support block 2 is fixedly connected to a sliding block 3 on the side near the support frame 1, and each sliding block 3 is inserted into the side wall of the adjacent support frame 1 and is slidably connected to the side wall of the support frame 1 along the length direction of the side wall of the support frame 1 to which it is inserted.

[0035] Reference Figure 2Each support block 2 has multiple abutment plates 21 on the side away from the connected sliding block 3. In this embodiment, the number of abutment plates 21 on one side of each support block 2 is four. The four abutment plates 21 are arranged in pairs, with the two abutment plates 21 in the same group located at intervals in a plane perpendicular to the length direction of the support block 2. The side of each abutment plate 21 that can abut against the pipe is an arc shape with the same shape as the adjacent support block 2.

[0036] Each abutment plate 21 is rotatably connected to two abutment rods 22 on the side closest to the support block 2, and the two abutment rods 22 are set at a certain angle. Each abutment rod 22 is rotatably connected to a top block 23 on the side away from the abutment plate 21. The support block 2 has a hole for each top block 23 to move in an arc around a direction perpendicular to the length direction of the support block 2.

[0037] Each top block 23 located at the edge of the hole in the support block 2 has a clamp 24 fixedly connected to the side away from the other top block 23 connected to the same abutment plate 21. Each clamp 24 is L-shaped, and the end of each clamp 24 can abut against the adjacent pipe sidewall. Each clamp 24 can move into the support block 2 under the action of the top block 23. A tension spring 25 is fixedly connected between the two top blocks 23 connected to the same abutment plate 21, and a pressure spring 26 is fixedly connected between adjacent top blocks 23 connected to the two abutment plates 21 in the same group.

[0038] During the process of supporting the pipeline, the pipeline is placed on the support block 2. Then, the pipeline presses against the four abutment plates 21 on the support block 2, causing each abutment plate 21 to move closer to the support block 2. During the movement of each abutment plate 21, it drives the two connected abutment rods 22 to move. During the movement of each abutment rod 22, it drives the connected top block 23 to move along the through hole opened inside the support block 2. This allows the top block 23 connected with the clamp 24 to move the connected clamp 24 out of the support block 2, thereby clamping the pipeline placed on the support block 2 and initially determining the position of the pipeline. Afterward, the staff can realize the docking between different pipelines by moving the sliding block 3.

[0039] Then, workers can use welding to further connect the pipe to the support block 2, and the support block 2 to the support frame 1. This achieves a stable connection between the pipe and the support frame 1.

[0040] The sliding block 3 and the supporting block 2 are used to move the pipe, which facilitates the process of placing the pipe on the support frame 1 and speeds up the work efficiency when connecting and connecting the pipes.

[0041] Reference Figure 3Two movable lead screws 4 are also provided between the two sliding blocks 3 connected to the upper bottom edge. Each movable lead screw 4 is a bidirectional lead screw. The end of each movable lead screw 4 passes through the side wall of the adjacent sliding block 3 and is rotatably connected to the side wall of the sliding block 3. The two movable lead screws 4 are horizontally arranged and are spaced apart by a certain distance. A driven gear 41 is fixedly sleeved in the middle position of each movable lead screw 4. The two driven gears 41 are arranged correspondingly, and the same drive gear 42 is meshed below the middle position of the two driven gears 41. A drive shaft 43 is fixedly connected through the middle of the drive gear 42. A drive sprocket 44 is fixedly sleeved at the end of the drive shaft 43 away from the drive gear 42, and a drive chain 45 is meshed on the drive sprocket 44. The end of the drive chain 45 away from the drive shaft 43 passes through the side wall of the support frame 1 and is located below the bottom plate of the trapezoidal support frame 1 near one of the inclined sides.

[0042] A buckle 11 is fixedly connected to one side wall of the support frame 1 near the drive chain 45, and the buckle 11 can restrict the position of the drive chain 45.

[0043] When it is necessary to adjust the position of the two support blocks 2 located on the bottom edge of the trapezoidal support frame 1, the drive chain 45 is pulled, the drive chain 45 drives the drive sprocket 44 to rotate, the drive sprocket 44 drives the drive shaft 43 to rotate, the drive shaft 43 drives the drive gear 42 to rotate, the drive gear 42 drives the two driven gears 41 and the movable screw 4 connected to the two driven gears 41 to rotate, the two movable screws 4 drive the two connected sliding blocks 3 to move relative to each other during the rotation, thereby realizing the adjustment of the relative position of the two support blocks 2 located on the bottom edge of the trapezoidal support frame 1 and the pipes located on the two support blocks 2.

[0044] Reference Figure 4 Each sliding block 3 located on the inclined side of the support frame 1 is penetrated and fixedly connected to two moving chains 5, and the two moving chains 5 penetrating the same sliding block 3 are parallel to each other and are spaced apart by a certain distance.

[0045] Each moving chain 5 has two meshing moving sprockets 51 inside, and the moving sprockets 51 inside two adjacent moving chains 5 are arranged one-to-one. The same moving shaft 52 is passed through and fixedly connected between the two corresponding moving sprockets 51, and both ends of the moving shaft 52 are rotatably connected to the side wall of the support frame 1. One end of each lower moving shaft 52 passes through the side wall of the support frame 1 and is fixedly connected to a handle 521. Each handle 521 is passed through and connected to a fixing bolt 522, and the end of each fixing bolt 522 passing through the handle 521 can abut against the side wall of the support frame 1.

[0046] When it is necessary to move the support block 2 located on the inclined side of the support frame 1, turn the handle 521. The handle 521 drives the moving shaft 52 to rotate. During the rotation of the moving shaft 52, the moving sprocket 51 connected to it rotates. During the rotation of the moving sprocket 51, the moving chain 5 rotates. Since the moving chain 5 is fixedly connected to the sliding block 3, the moving chain 5 can drive the sliding block 3 to move during the movement. Since the sliding block 3 is fixedly connected to the support block 2, the process of moving the support block 2 by turning the handle 521 can be realized. When the support block 2 moves to the appropriate position, the fixing bolt 522 can be tightened so that one end of the fixing bolt 522 abuts against the side wall of the support frame 1, thereby fixing the position of the handle 521 and the support block 2.

[0047] Reference Figure 1 Multiple ladders 12 are fixedly connected to the side wall of the support frame 1. These ladders 12 are parallel to each other and spaced apart, extending from the bottom to the top of the support frame 1. In this embodiment, each ladder 12 is C-shaped, with the C-shaped opening facing one side of the support frame 1. A horizontally positioned maintenance platform 13 is also fixedly connected to the side wall of the support frame 1 near its upper surface.

[0048] When it is necessary to inspect and repair the pipes on the support frame 1, workers can climb up to the top of the support frame 1 using multiple ladders 12 or stand on the inspection platform 13 to carry out the inspection and repair operations on the pipes on the support frame 1 that need to be inspected.

[0049] The implementation principle of the arched support and protection structure for curved road pipes used in municipal heating according to the embodiments of this application is as follows: In actual use, the pipe is placed on the support block 2, so that the four claws 24 on each support block 2 can clamp the pipe placed on the support block 2. Then, the workers can weld the pipe to the support block 2 or the pipe to the claws 24 to further fix the relative position between the pipe and the support block 2.

[0050] Then, by turning the two handles 521 and the drive chain 45, multiple support blocks 2 are moved. During the movement of the support blocks 2, the pipes placed on the support blocks 2 are moved, thereby realizing the docking process between multiple different pipes.

[0051] When it is necessary to inspect and maintain the pipes on the support frame 1, workers can climb onto the support frame 1 or the maintenance platform 13 via the ladder 12 and then carry out the inspection and maintenance operations on the pipes on the support frame 1.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
