Description

Technical Field

[0001] This utility model relates to the technical field of pressure pipeline construction equipment, and in particular to a pressure pipeline transportation device inside a casing. Background Technology

[0002] Penstocks refer to all pipelines subjected to internal or external pressure. Based on their installation method, they can be categorized into three types: open-air, dam-type, and underground. Underground penstocks mainly include water pipes, gas pipes, and other transport pipelines buried underground. When laid beneath existing structures such as highways, trenchless drilling is commonly used for installation. An outer casing is installed within the borehole to protect the penstock from structural damage caused by external pressure.

[0003] However, during construction, traditional traction installation methods face significant challenges due to the limited working space created by drilling operations and the internal structural characteristics of the outer casing. Because the outer casing contains uneven structures such as working platforms, frequent manual adjustments to the pipe's posture are required when using a traction machine to pull the pressure pipeline over these platforms, greatly hindering construction efficiency. More seriously, the continuous friction between the pressure pipeline and the casing during transport can easily cause pipe wall wear and end deformation, posing a double threat to project quality.

[0004] Based on this, the present invention provides a pressure pipeline transportation device within a casing to solve the problems existing in the prior art. Utility Model Content

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application.

[0053] As per the instruction manual Figures 1-10 As shown, this utility model provides a technical solution:

[0054] A pressure pipeline transportation device within a casing is used to transport a pressure pipeline 7 when it is installed inside a casing 1 under an existing building. The device includes a transport track 3, a support and compensation mechanism 4, and a transport trolley 5. Specifically, the transport track 3 is symmetrically arranged inside the casing 1, with its ends resting on a working platform 2 inside the casing 1. The support and compensation mechanism 4 is installed below the transport track 3 and located between adjacent working platforms 2. While supporting the transport track 3, it also compensates for the height of the working platforms 2, creating a continuous transition support surface for the transport track 3. This effectively eliminates track settlement differences caused by segmented platform arrangement, ensuring the transport trolley 5 maintains a horizontal running plane, allowing for horizontal transport of the pressure pipeline 7. The transport trolley 5 is movably mounted on the two symmetrically arranged transport tracks 3, and symmetrically arranged pipeline positioning side plates 6 clamp the pressure pipeline 7, ensuring precise control of the pipeline's transport posture even under complex working conditions and guaranteeing the stability of the pressure pipeline 7 during transportation.

[0055] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the transport track 3 adopts a segmented assembly structure, specifically including multiple track sections 31 and track connecting plates 33. Each track section 31 is an H-shaped steel plate structure. Positioning holes 32 are provided on both sides of the lower flange of the track section 31 to cooperate with the support compensation mechanism 4, controlling the position of the support compensation mechanism 4 on the lower side of the track section 31. A toothed groove 35 is also provided on the outer side of the upper center of each track section 31. The toothed groove 35 cooperates with the transport trolley 5 after installation, engaging with it to drive the transport trolley 5 to move on the transport track 3. The track connecting plates 33 are symmetrically arranged on both sides of the connection between adjacent track sections 31 and are connected to the track sections 31 via track connecting pins 34, forming a continuous track transport structure.

[0056] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the support compensation mechanism 4 includes a rod sleeve 41, a rod core 42, and a rotating support plate 45. The rod core 42 is movably disposed in a slot at the upper end of the rod sleeve 41 and is connected to the rod sleeve 41 by a positioning pin 46. A locking block 43 is provided at the upper end of the rod core 42. The locking block 43 engages with the wing plates on both sides of the lower side of the track section 31 and is connected to the positioning hole 32 by a positioning bolt 47. The rotating support plate 45 is installed at the lower end of the rod sleeve 41 by a threaded connecting rod 44 and is rotatably connected to the threaded connecting rod 44. This allows the rotating support plate 45 to match the bottom slope of the sleeve 1 during installation, ensuring the stability of the support compensation mechanism 4 during support.

[0057] Specifically, such as Figure 5 and Figure 6 As shown, the rod core 42 is also provided with several through holes that cooperate with the positioning pin 46. When in use, the positioning pin 46 is passed through the through holes at different positions to fix the relative position of the rod sleeve 41 and the rod core 42, thereby adjusting the height of the support compensation mechanism 4 to meet the usage requirements under different working conditions.

[0058] In a preferred embodiment, such as Figure 1 , Figure 2 , Figure 7 , Figure 9 and Figure 10 As shown, the transport trolley 5 includes a chassis base plate 51 and a drive mechanism mounted on the underside of the chassis base plate 51. The pipe positioning side plates 6 are mounted on both sides of the upper side of the chassis base plate 51 for fixing the pressure pipe 7. The drive mechanism has one or more located on the underside of the chassis base plate 51, depending on the diameter and volume of the pressure pipe to be transported, and engages with the toothed groove 35 to drive the chassis base plate 51 to move on the transport track 3.

[0059] Specifically, such as Figure 2 and Figure 7 As shown, the vehicle body floor plate 51 is symmetrically provided with guide grooves 52. The guide grooves 52 and the guide clips 61 provided on the lower side of the pipe positioning side plate 6 engage with each other. The guide clips 61 are used to engage the guide clips 61 in the guide grooves 52 during use, so as to connect the vehicle body floor plate 51 and the pipe positioning side plate 6. Under the guidance of the guide grooves 52, the staff can adjust the distance between the two pipe positioning side plates 6 according to the outer diameter of the pressure pipe 7, so as to match the fixing requirements of pressure pipes 7 with different outer diameters.

[0060] Specifically, such as Figure 2 and Figure 7As shown, the vehicle body floor plate 51 is also provided with a positioning slot 55 that communicates with the guide groove 52. The positioning slot 55 is used in conjunction with the limiting member 56 to fix the position of the pressure pipe 7 by inserting the limiting member 56 into the positioning slot 55 on the outside of the pipe positioning side plate 6 during the adjustment of the position of the pipe positioning side plate 6, so as to prevent the pressure pipe 7 from moving during transportation and ensure the stability and safety of transportation.

[0061] Specifically, such as Figure 7 and Figure 10 As shown, guide members 53 are symmetrically arranged on the lower side of the vehicle body floor 51. The guide members 53 have a sliding groove that engages with the upper wing plate of the track section 31 and can slide along the upper wing plate of the track section 31 after installation. A drive wheel 54 is rotatably mounted on the upper side of the sliding groove of the guide member 53, and the drive wheel 54 meshes with the toothed groove 35.

[0062] Specifically, such as Figure 7 and Figure 10 As shown, the drive mechanism includes a drive motor 59 and a drive rod 57. The drive motor 59 is fixedly mounted on the underside of the vehicle body floor 51, and a drive gear 50 is mounted on the drive end of the drive motor 59. The drive gear 50 meshes with a driven gear 58 mounted on the drive rod 57, and is used to drive the drive rod 57 to rotate via the drive motor 59. The drive rod 57 is rotatably mounted on the underside of the vehicle body floor 51, and its end is fixedly connected to the drive wheel 54. In use, the drive rod 57 drives the drive wheel 54 to rotate, and the meshing force between the drive wheel 54 and the tooth groove 35 drives the vehicle body floor 51 to move horizontally on the track section 31 to transport the pressure pipe 7.

[0063] The usage process and operating principle of the pressure pipeline transportation device inside the casing described in this utility model include: during installation, one end of the end track section 31 is overlapped and fixed on the working platform 2. Then, according to the transportation length, a corresponding number of track sections 31 are selected and connected using track connecting plates 33 to form a transportation track 3. During the installation process, the corresponding height and number of support compensation mechanisms 4 are adjusted and installed according to the height of the working platform 2 and the length of the transportation track 3. After the rotating support plate 45 is pressed tightly against the bottom inclined surface of the casing 1, the stability of the overall transportation track 3 is checked. After the stability of the transportation track 3 meets the requirements, the transportation trolley 5 and the pipeline positioning side plate 6 are installed and adjusted so that the transportation trolley 5 can run stably on the surface of the transportation track 3. Finally, the pressure pipeline 7 is placed on the transportation trolley 5 outside the casing 1, and the pressure pipeline 7 is positioned using the pipeline positioning side plate 6. After positioning, the drive motor 59 is turned on to transport the pressure pipeline 7 inside the casing 1. After transportation to the designated position, the limiting piece 56 is pulled out to release the fixation of the pressure pipeline 7, which facilitates the installation and construction of the pressure pipeline 7.

[0064] It should be noted that the drive motor 59 mentioned above is a device with relatively mature existing technology, and the specific model of the drive motor 59 can be selected and used and powered according to actual needs, which will not be elaborated here.

[0065] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
