Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and in particular to a pipeline internal transport support trolley. Background Technology

[0002] In pipeline internal maintenance or corrosion protection and insulation work, traditional construction methods typically involve manual handling. Workers must carry cut wooden planks into the pipeline, which are then horizontally erected as temporary work platforms, or they may directly carry tools and materials by hand. However, different pipelines have different diameters, requiring the planks to be recut according to the pipeline size for each construction project. Furthermore, standard wooden planks are relatively large, making them difficult to move within narrow pipelines and resulting in high labor intensity. Fixed platforms cannot be moved, requiring workers to frequently travel back and forth to retrieve tools and materials, which is inconvenient. Simple wooden plank supports lack reliable fixing mechanisms, posing a risk of slippage and affecting construction safety.

[0003] Therefore, there is an urgent need for a pipeline internal transport support trolley that is low in labor intensity, easy to operate, and ensures construction safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pipeline internal transport support trolley that overcomes the defects of high labor intensity, inconvenient operation and impact on construction safety, thereby achieving the goals of low labor intensity, convenient operation and guaranteed construction safety.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a pipeline internal transport support trolley, including a shell, at least two sets of moving components located on different planes are provided on the outer periphery of the shell, the moving components include at least 3 telescopic rods, one end of the telescopic rod is provided with a pulley, a support plate is vertically fixed inside the shell, a slide rail is provided on the top of the support plate, and a placement platform is provided on the slide rail.

[0006] Furthermore, the telescopic rod includes a fixed rod and a connecting rod. The fixed rod is fixedly mounted on the housing, and a first connecting hole is provided on the upper part of the fixed rod. One end of the connecting rod is adjustablely sleeved in the fixed rod, and a pulley is provided at the other end of the connecting rod. The connecting rod is evenly provided with a plurality of second connecting holes along the axial direction that cooperate with the first connecting hole on the fixed rod. By selecting the second connecting holes at different positions of the connecting rod to align with the first connecting holes of the fixed rod, the two are fixed by using a connector.

[0007] Furthermore, the telescopic rod is a handwheel worm gear.

[0008] Furthermore, the storage platform is located below the central axis of the shell, and is perpendicular to the support plate. It can reciprocate linearly along the support plate under the guidance of the slide rail.

[0009] Furthermore, the pulley is equipped with a fixing buckle.

[0010] Furthermore, the pulley is a directional pulley with an anti-slip structure added to its surface.

[0011] Furthermore, the anti-slip structure is an anti-slip pattern, groove, or toothed structure.

[0012] Furthermore, the anti-slip structure is made of a high-friction material.

[0013] Furthermore, both the first and second connecting holes are threaded holes, and the connecting parts are threaded fasteners.

[0014] Furthermore, both the first and second connecting holes are through holes, and the connector is a pin.

[0015] This utility model adopts the above technical solution and has the following advantages compared with the prior art: the telescopic rod adopts multi-stage connection hole adjustment or handwheel worm gear, which can flexibly adjust the extension length of the telescopic rod, so that the pulley is always in close contact with the pipe, adapting to pipes of different diameters, and eliminating the need for manual handling of wooden boards and tools in narrow pipes, thus reducing labor intensity; the storage platform is slidably connected to the support plate through the slide rail, and can move back and forth along the pipe axis, making it convenient to retrieve the materials and equipment required for construction, and is easy to operate; the pulley is equipped with a fixing buckle, which can lock the pulley to prevent the trolley from slipping during construction, ensuring operational stability and construction safety; the moving component is retractable, reducing the space occupied when not in use and improving portability; an anti-slip structure is added to the surface of the pulley, made of high-friction material, to increase the friction with the pipe and improve stability.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] Examples, such as Figure 1-4 As shown, a pipeline internal transport support trolley includes a housing 1. At least two sets of movable components 10 located on different planes are provided on the outer periphery of the housing 1 (two sets in this example). A support plate 6 is vertically fixed inside the housing 1. A slide rail 9 is provided on the top of the support plate 6, and a placement platform 5 is provided on the slide rail 9. The placement platform 5 is located below the central axis of the housing 1. After items are placed on the placement platform 5, the overall center of gravity shifts downward, reducing the risk of the trolley swaying or tipping over. The placement platform 5 is perpendicular to the support plate 6 and can reciprocate linearly along the support plate 6 under the guidance of the slide rail 9, facilitating the retrieval of materials and equipment required for construction. The slide rail 9 is prior art and will not be described in detail here.

[0020] The movable component 10 includes at least three telescopic rods, four in this example. One end of each telescopic rod is provided with a pulley 3. Each telescopic rod includes a fixed rod 2 and a connecting rod 8. The fixed rod 2 is fixedly mounted on the housing 1. The upper part of the fixed rod 2 is provided with a first connecting hole (not shown in the figure). One end of the connecting rod 8 is adjustablely fitted into the fixed rod 2. The pulley 3 is provided at the other end of the connecting rod 8. The connecting rod 8 is provided with a plurality of second connecting holes 11 that mate with the first connecting holes on the fixed rod 2 along the axial direction. By selecting different positions of the second connecting holes 11 on the connecting rod 8 to align with the first connecting holes on the fixed rod 2, the two are fixed by using a connector 4.

[0021] Both the first connecting hole and the second connecting hole 11 are threaded holes, and the connector 4 is a threaded fastener.

[0022] The first connecting hole and the second connecting hole 11 can both be through holes, and the connector 4 is a pin.

[0023] Telescopic poles can also use handwheels and worm gears, where turning the handle rotates the worm gear, thus achieving linear motion. Handwheels and worm gears are existing technology and will not be described in detail here.

[0024] The pulley 3 is equipped with a fixing buckle (not shown in the figure), which can lock the pulley 3 to prevent the trolley from sliding during construction.

[0025] The pulley 3 is a directional pulley with an anti-slip structure added to its surface. This structure can be an anti-slip pattern, groove, or toothed structure. The material is a high-friction material, such as rubber or polyurethane, which increases the friction with the pipe 7 and improves stability.

[0026] The shape of shell 1 is not limited; in this example, it is cylindrical.

[0027] Instructions for use: Place the pipe support maintenance trolley in the pipe 7 to be maintained, then adjust the telescopic rod to the appropriate length, ensuring the pulley 3 is in close contact with the pipe 7, and lock the telescopic rod securely. Place the necessary materials and equipment on the platform 5, and push the trolley along the pipe 7 to the target maintenance position. Once at the maintenance position, lock the pulley 3 with the fixing buckles to prevent the trolley from slipping during construction and ensure operational stability. During maintenance, the pull-out platform 5 can reciprocate linearly along the support plate 6 under the guidance of the slide rail 9, facilitating the retrieval of necessary materials and equipment.

[0028] The telescopic rod uses multi-stage connecting holes for adjustment or a handwheel worm gear, allowing for flexible adjustment of the extension length. This ensures that the pulley 3 remains tightly fitted to the pipe 7, adapting to pipes of different diameters. Furthermore, it eliminates the need for manual handling of planks and tools within narrow pipes 7, reducing labor intensity. The storage platform 5 is slidably connected to the support plate 6 via a slide rail 9, allowing for reciprocating movement along the pipe 7 axis. This facilitates the retrieval of materials and equipment required for construction, making operation convenient. The pulley 3 is equipped with a locking buckle to prevent slippage of the trolley during construction, ensuring operational stability and construction safety. The retractable moving component 10 reduces space occupation when not in use, improving portability. An anti-slip structure made of high-friction material is added to the surface of the pulley 3 to increase friction with the pipe 7, enhancing stability.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
