Description

Technical Field

[0001] This utility model relates to the field of pipeline transportation equipment technology, and in particular to a natural gas flow meter and a transportation device for pipeline sections. Background Technology

[0002] In existing technologies, the main method for transporting flow meters and their associated installation pipe sections at gas transmission stations of long-distance natural gas pipelines and national oil and gas high-flow metering stations is by using forklifts. The specific installation process involves forklifting the flow meter and installation pipe section from the warehouse to the process site, where personnel use tools to install them on the platform. The specific disassembly process involves personnel using tools to disassemble the flow meter and installation pipe section, and then using a forklift to transport the flow meter and installation pipe section back to the warehouse.

[0003] This forklift transport method has low efficiency. The forklifts are small and can only transport one flow meter or pipe section at a time, resulting in low work efficiency. Furthermore, there are no stable fixed parts during the transport process, making the safe transport process uncontrollable. Utility Model Content

[0004] This invention addresses the technical problems of low transportation efficiency and inability to achieve stable transportation in existing methods of transporting natural gas flow meters and pipeline sections by forklift, and provides a transportation device for natural gas flow meters and pipeline sections.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A natural gas flow meter and pipeline transport device includes an AGV trolley, a base plate fixed to the AGV trolley, and a support mechanism mounted on the base plate. The support mechanism includes at least two support frames arranged in a straight line and spaced apart. The lower end of each support frame is connected to the base plate, and at least one placement frame is fixedly connected to the upper end of each support frame. Both ends of each placement frame extend out of the corresponding sides of the support frame, and the ends form an upper opening structure with the corresponding support frame for placing the pipeline. The base plate is also equipped with an even number of first support blocks. Each first support block is arranged in pairs and spaced apart to place the flow meter between the two first support blocks in each pair.

[0007] The beneficial effects of this utility model are as follows: During transportation, the pipeline is hoisted onto the placement frame, and the placement frame, which is fixedly installed on different support frames, supports the pipeline at different positions, maintaining the balance of the pipeline during transportation. At the same time, the flow meter is supported by the first support block. This allows the AGV trolley to simultaneously complete the transportation of multiple flow meters and multiple pipelines, improving the technical problem of low transportation efficiency in the existing method of forklift transportation of natural gas flow meters and pipeline sections. In this process, the pipeline is supported in the upper open structure, which can improve the technical problem of unstable transportation in the existing method of forklift transportation of natural gas flow meters and pipeline sections.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the two sides of the support frame are inclined planes that slope towards each other from bottom to top, each support frame is provided with at least two vertically spaced placement racks, and the U-shaped grooves formed by each of the upper opening structures have equal widths.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the support frame with inclined structure on both sides can ensure its stability when supporting the pipe, and the U-shaped grooves formed by each upper opening structure have equal width, so that the lower placement frame protrudes relative to the upper placement frame, forming a space that is convenient for placing the pipe, and also convenient for removing the pipe.

[0011] Furthermore, each of the placement racks includes a placement plate fixedly connected to the support frame and two stops respectively installed at both ends of the placement plate. Both ends of the placement plate extend out of the corresponding sides of the support frame, and the lower ends of the stops are installed on the placement plate. The placement plate, the two stops, and the support frame together form two U-shaped grooves with an upper opening structure.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the placement plate, the stop bar, and the corresponding support frame form an upper opening structure, and the pipe can be hoisted into the upper opening structure during use.

[0013] Furthermore, the placement plate extends from both ends of the corresponding support frame in an inclined structure with the ends tilted downwards.

[0014] The beneficial effects of adopting the above-mentioned further solution are: when the pipe is placed in the upper opening structure, the pipe will roll and abut against the stop bar under its own weight, which relatively ensures stability during transportation, and when the pipe is lifted out, the pipe is relatively close to the lateral opening space formed by the ends of the upper and lower placement plates, which facilitates the lifting out of the pipe.

[0015] Furthermore, the stop lever is an inclined structure, with its upper end tilted away from its corresponding support frame.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it increases the opening width of the U-shaped groove formed by the upper opening structure, especially when the pipe is hoisted between the upper and lower placement plates, which facilitates the pipe hoisting operation.

[0017] Furthermore, the lower ends of the stop bars are slidably connected to the corresponding placement plates, and both the stop bars and the placement plates are fitted with insert rods.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it allows the height of the upper and lower ends of the stop bar relative to the placement plate to be adjusted by sliding the stop bar, which facilitates the hoisting operation of the pipeline.

[0019] Furthermore, the base plate is fixed with multiple spaced slide rails, and the lower end of each support frame is slidably connected to the slide rails, and any support frame is slidably connected to at least two slide rails simultaneously.

[0020] The beneficial effect of adopting the above-mentioned further solution is that it allows for the adjustment of the spacing between each support frame by sliding, thereby enabling the support and transportation of pipes of different lengths.

[0021] Furthermore, an even number of support frames are provided, and they form a group in pairs; each support frame is connected to a mounting plate, one end of the mounting plate is connected to the corresponding support frame, and the other end is fixed with at least one support member supporting the base plate, and the other ends of the two mounting plates located on the two support frames forming a group are arranged facing each other, and two spaced second support blocks are installed on the upper side of the other end of each mounting plate.

[0022] The beneficial effects of adopting the above-mentioned further scheme are: during hoisting, the flow meter can be hoisted onto two second support blocks forming a group, and the two second support blocks support the two ends of the flow meter respectively, so as to increase the transport capacity, and at the same time, the placement of the flow meter forms a stabilizing effect on the support frame.

[0023] Furthermore, each of the aforementioned support components is a roller, and one end of the mounting plate is slidably connected to the corresponding support frame.

[0024] The advantage of adopting the above-mentioned further solution is that it enables the support of flow meters of different lengths by changing the distance between two adjacent mounting plates through the sliding direction.

[0025] Furthermore, each of the mounting plates has a sliding groove on its upper side at the other end, and a plurality of limiting blocks are provided at intervals at the bottom of the sliding groove. The lower end of each of the second support blocks extends into the corresponding sliding groove and has a slot for the corresponding limiting block to be inserted.

[0026] The beneficial effect of adopting the above-mentioned further solution is that it allows for adjustment of the spacing between the two second support blocks forming a pair, and the second support blocks are limited by the limiting block to maintain the spacing between the two second support blocks, thereby achieving support for flow meters of different sizes.

[0041] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0042] Example 1

[0043] like Figure 1 and Figure 2 A natural gas flow meter and pipeline transportation device includes an AGV trolley 1, a base plate 2 fixed on the AGV trolley 1, and a support mechanism installed on the base plate 2. The support mechanism includes at least two support frames 3 arranged in a straight line and spaced apart. The lower end of each support frame 3 is connected to the base plate 2, and the upper end of each support frame 3 is fixedly connected to at least one placement frame 4. Both ends of each placement frame 4 extend out of the sides of the corresponding support frame 3, and the ends form an upper opening structure with the corresponding support frame 3 for placing the pipeline. The base plate 2 is also equipped with an even number of first support blocks 6. Each first support block 6 forms a group in pairs and is spaced apart, so as to place the flow meter between the two first support blocks 6 in each group.

[0044] The beneficial effects of this embodiment are as follows: During transportation, the pipeline is hoisted onto the placement frame 4, and the placement frame 4, which is fixedly installed on different support frames 3, supports the pipeline at different positions, maintaining the balance of the pipeline during transportation. At the same time, the flow meter is supported by the first support block 6, so that the AGV trolley 1 can simultaneously complete the transportation of multiple flow meters and multiple pipelines, improving the technical problem of low transportation efficiency in the existing method of forklift transportation of natural gas flow meters and pipeline sections. In this process, the pipeline is supported in the upper opening structure, which can improve the technical problem of unstable transportation in the existing method of forklift transportation of natural gas flow meters and pipeline sections.

[0045] As a specific embodiment of the above, the base plate 2, support frame 3, placement frame 4, and first support block 6 can all be made of steel. Multiple pads are fixed on the AGV trolley 1 to secure the base plate 2. The support frame 3 is a frame structure; in this embodiment, it can be a rectangular or isosceles trapezoidal frame structure.

[0046] Multiple support frames 3 are arranged in the middle of the base plate 2, and multiple first support blocks 6 are evenly distributed on both sides of the multiple support frames 3 arranged in a row to ensure stability during transportation.

[0047] Based on the above embodiment, the opposing sides of the two first support blocks 6 forming a pair are each formed with a first inclined surface to form a "V" shaped groove structure, which facilitates the placement of the flow meter and provides stable support for the flow meter.

[0048] Among them, the AGV trolley 1 can be purchased from the market. It has a laser navigation and positioning system. Through high-speed image data acquisition function and embedded algorithm platform software, it can realize the complete automatic path operation. It can achieve a positioning accuracy of ±5mm at different workstations, and perform inventory loading (unloading) of flow meters, on-site task assistance in the complete delivery of flow meters and straight pipe sections, realizing an unmanned automatic delivery mode.

[0049] AGV 1 has visual positioning and collaborative functions: visual positioning is mainly used when the AGV is unloading materials (the robot grabs the flow meter) and disassembling the flow meter (visual positioning); the collaborative function is mainly used at long distances (relative to the AGV) when multiple machines need to be transferred.

[0050] Example 2

[0051] like Figure 2 and Figure 3 Based on embodiment 1, the two sides of the support frame 3 are inclined plane structures that slope towards each other from bottom to top. Each support frame 3 is provided with at least two vertically spaced placement racks 4, and the U-shaped grooves formed by each upper opening structure have equal widths.

[0052] The beneficial effect of adopting the preferred solution in the above embodiments is that the support frame 3 with inclined structure on both sides can ensure its stability when supporting the pipe, and the U-shaped groove formed by each upper opening structure has the same width, so that the lower placement frame 4 protrudes relative to the upper placement frame 4, forming a space that is convenient for placing the pipe, and also convenient for removing the pipe.

[0053] That is, in this embodiment, the support frame 3 is an isosceles trapezoidal frame structure. And the height of the uppermost placement rack 4 is lower than the top of the support frame 3, so as to ensure that the end of the uppermost placement rack 4 can form a U-shaped groove with an upper opening structure relative to the support frame 3, thus ensuring the stability of the pipeline during transportation.

[0054] Example 3

[0055] like Figure 2 and Figure 3 Based on embodiments 1 and 2, each placement rack 4 includes a placement plate 41 fixedly connected to the support frame 3 and two stop bars 42 respectively installed at both ends of the placement plate 41. Both ends of the placement plate 41 extend out of the corresponding sides of the support frame 3, and the lower end of the stop bar 42 is installed on the placement plate 41. The placement plate 41, the two stop bars 42 and the support frame 3 together form two U-shaped grooves with an upper opening structure.

[0056] The advantage of adopting the preferred solution in the above embodiments is that the placement plate 41, the stop bar 42 and the opposite support frame 3 form an upper opening structure, and the pipe can be hoisted into the upper opening structure when in use.

[0057] As a specific embodiment of the above, the placement plate 41 is arranged horizontally and its middle end is fixedly (welded) to the support frame 3.

[0058] Example 4

[0059] like Figure 2 and Figure 3 Based on embodiments 1-3, the placement plate 41 extends from both ends of the corresponding support frame 3 and has an inclined structure with the ends tilted downwards.

[0060] The beneficial effect of adopting the preferred solution in the above embodiments is that when the pipe is placed in the upper opening structure, the pipe will roll under its own weight and abut against the stop bar 42, which relatively ensures stability during transportation. When the pipe is lifted out, the pipe is relatively close to the lateral opening space formed by the ends of the upper and lower placement plates 41, which facilitates the lifting out of the pipe.

[0061] As a specific embodiment of the above, the tilt angle of the end of the placement plate 41 can be 1°, 2°, 3°, etc.

[0062] As a parallel solution of the above embodiments, the placement plate 41 extends from both ends of the corresponding support frame 3 and is inclined upwards. This inclined structure causes the pipe to roll and abut against the support frame 3, but it is not convenient to lift the pipe out.

[0063] Example 5

[0064] like Figure 2 and Figure 3 Based on embodiments 1-4, the stop bar 42 is an inclined structure as a whole, and the upper end is inclined in a direction away from its corresponding support frame 3.

[0065] The advantage of adopting the preferred solution in the above embodiments is that it increases the opening width of the U-shaped groove formed by the upper opening structure, especially when the pipe is hoisted between the upper and lower placement plates 41, which facilitates the hoisting operation of the pipe.

[0066] As a specific embodiment of the above, the tilt angle of the lever 42 can be 3°, 5°, 7°, and 9°, etc.

[0067] Example 6

[0068] like Figure 2 and Figure 3 Based on embodiments 1-5, the lower end of the stop bar 42 is slidably connected to the corresponding placement plate 41, and the stop bar 42 and the placement plate 41 are both inserted with the insertion rod 43.

[0069] The advantage of adopting the preferred solution in the above embodiments is that the height of the upper and lower ends of the stop bar 42 relative to the placement plate 41 can be adjusted by sliding the stop bar 42, which facilitates the hoisting operation of the pipeline.

[0070] As a specific embodiment of the above, the stop bar 42 has multiple positioning holes 421 spaced apart along its length, and both ends of the placement plate 41 have insertion holes 411 that can connect to the corresponding positioning holes 421. The insertion rod 43 is inserted into the connecting insertion hole 411 and the positioning hole 421. This allows the height of the insertion rod 43 to be adjusted by inserting it into the positioning holes 421 at different positions.

[0071] The plate 41 has a through hole at its end to accommodate and allow the stop bar 42 to be inserted, thus enabling the stop bar 42 to slide.

[0072] The positioning hole 421 can be a blind hole or a through hole.

[0073] Example 7

[0074] like Figure 2 and Figure 3Based on embodiments 1-6, the base plate 2 is fixed with multiple spaced slide rails 5, and the lower end of each support frame 3 is slidably connected to the slide rail 5, and any support frame 3 is slidably connected to at least two slide rails 5 at the same time.

[0075] The advantage of adopting the preferred solution in the above embodiments is that the spacing of each support frame 3 can be adjusted by sliding to achieve support and transportation operations for pipes of different lengths.

[0076] As a specific embodiment of the above, the slide rail 5 can be made of steel rail with an "I" shaped cross-section, and the support frame 3 has a slot adapted to the slide rail 5 so as to engage and realize the sliding of the support frame 3.

[0077] In the diagram, only two slide rails 5 are shown.

[0078] Example 8

[0079] like Figure 3 and Figure 4 Based on embodiments 1-7, an even number of support frames 3 are provided, and they form a group in pairs; each support frame 3 is connected to a mounting plate 7, one end of the mounting plate 7 is connected to the corresponding support frame 3, and the other end is fixed with at least one support member 8 supporting the base plate 2, and the other ends of the two mounting plates 7 located on the two support frames 3 forming a group are arranged facing each other, and two spaced second support blocks 9 are installed on the upper side of the other end of each mounting plate 7.

[0080] The beneficial effect of adopting the preferred solution in the above embodiments is that, during hoisting, the flow meter can be hoisted onto two second support blocks 9 forming a group, and the two second support blocks 9 support the two ends of the flow meter respectively, so as to increase the transport capacity, and at the same time, the placement of the flow meter forms a stabilizing effect on the support frame 3.

[0081] In this embodiment, one end of the mounting plate 7 is fixedly or detachably connected to the support frame 3. The support frame 3 has an isosceles trapezoidal frame structure, and the mounting plate 7 is connected to the middle of the bottom end of the support frame 3.

[0082] Example 9

[0083] like Figure 3 and Figure 4 Based on embodiments 1-8, each support member 8 is a roller, and one end of the mounting plate 7 is slidably connected to the corresponding support frame 3.

[0084] The advantage of adopting the preferred solution in the above embodiments is that it enables the support operation of flow meters of different lengths by changing the distance between two adjacent mounting plates 7 by sliding the direction.

[0085] The rollers can be omnidirectional wheels, so that the braking function can prevent the mounting plate 7 from sliding automatically.

[0086] Based on the above embodiments, a slot 31 is provided through the support frame 3, and a mounting plate 7 is fixed with a card block that is adapted to and slidably connected to the slot 31 to achieve a sliding connection.

[0087] Example 10

[0088] like Figure 3 and Figure 4 Based on embodiments 1-9, each mounting plate 7 has a sliding groove 71 on the upper side of the other end. Multiple limiting blocks 72 are provided at intervals at the bottom of the sliding groove 71. The lower end of each second support block 9 extends into the corresponding sliding groove 71 and has a slot for the corresponding limiting block 72 to be inserted.

[0089] The advantage of adopting the preferred solution in the above embodiments is that it allows for adjusting the spacing between the pair of second support blocks 9, and limiting the second support blocks 9 by the limiting block 72, maintaining the spacing between the two second support blocks 9, and achieving support for flow meters of different sizes.

[0090] When adjusting the spacing, simply remove the second support block 9 from the slide groove 71 and place it at different positions on the slide groove 71.

[0091] As a specific embodiment of the above, the slide 71 is a U-shaped groove.

[0092] Based on the above embodiment, the cross-section of the limiting block 72 is an isosceles trapezoidal structure, which guides the lowering of the second support block 9 through its upper surface.

[0093] The two second support blocks 9 that form a pair are each formed with a first inclined surface on their opposite sides to form a "V" shaped groove structure, which facilitates the placement of the flow meter and provides stable support for the flow meter.
