Description

Technical Field

[0001] This application relates to the field of hydropower station construction technology, and in particular to a tailrace elbow pipe installation and transportation device. Background Technology

[0002] One part of the tailrace elbow pipe outlet section of the hydropower station is located outside the downstream side wall of the powerhouse (inside the tailrace branch tunnel (14)), and the other part is outside the limit position range of the crane hook of the powerhouse bridge crane. As a result, the above-mentioned elbow pipe cannot be directly hoisted into place by the bridge crane. This part of the elbow pipe needs to be placed by transportation. Conventional elbow pipe transportation adopts trolley transportation or elbow pipe placement on the track and hard dragging method. Trolley has a complex structure, large size, high cost, and is inconvenient for hoisting; the hard dragging method on the track requires grease to be applied to the track, which has a large safety risk, is easy to pull off the track, and causes environmental pollution.

[0027] To address the aforementioned problems, this application provides a tailrace elbow pipe installation and transportation device. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4The device shown is a tailrace elbow pipe installation and transportation device, including a traveling device 1, a connecting rod 2, and fasteners I3. Two sets of traveling devices 1 are symmetrically arranged and are detachably fastened to each other by fasteners I3 through the connecting rod 2 to form an I-shape. The fasteners I3 are a set of bolts and nuts. The connecting rod 2 is a long flat convex structure or a rectangular square tube. Both ends of the connecting rod 2 are connected to equilateral angle steel with the same size as the square tube. The equilateral angle steel has a through hole in the middle to facilitate connection with the traveling device 1 through fasteners I3. After bolt holes are constructed at both ends of the traveling device 1, it is detachably fastened to the device by bolts and nuts.

[0029] The traveling device 1 of this application includes end beams 4, main beams 5, inclined pads 6, fasteners II 7, and tank vehicles 8. End beams 4 are vertically arranged at both ends of the main beam 5, and the end beams 4 and the main beam 5 are detachably fastened together by fasteners II 7. Tank vehicles 8 are arranged at both ends below the end beams 4. The end beams 4 are I-beams, and a row of equally spaced through holes is opened in the middle of the web of the I-beam to facilitate the connection of the connecting rods 2. The main beam 5 is an I-beam, and eight through holes are opened in the bottom flange of the I-beam to facilitate the connection of the tank vehicles 8. The end beams 4 and the main beam 5 are detachably fastened together by the inclined pads 6 with wedge-shaped plate structure and fasteners II 7. Fasteners II 7 are a set of bolts and nuts.

[0030] A steel support 9 is installed on a concrete base slab 13. A track foundation 10 is installed on the steel support 9. A track 11 is installed on the track foundation 10. A tank vehicle 8 is slidably connected to the track 11. The track foundation 10 is an H-beam; the track 11 is a channel steel; and the stop block 12 is a steel plate. The track foundation 10 and the track 11 have the same model and length. After the track foundation 10 is connected to the track 11, it is connected to the steel support 9 and symmetrically arranged along the center line of the elbow pipe installation. Stop blocks 12 are installed at both ends of the track 11. The tank vehicle 8 is a tank-shaped slider, which facilitates nesting and sliding on the track 11 and abuts against the stop block 12 during sliding to prevent slippage.

[0031] like Figures 1 to 4 As shown, all steel components are manufactured into finished products. The two walking devices are assembled into a whole for later use as shown in the figure. The two sets of track foundations, tracks, and stops are welded into a whole for later use. The steel supports are manufactured into finished products for later use.

[0032] Before use, measure and mark the center line for the elbow pipe installation on the concrete base slab 13. Arrange steel supports on both sides of the center line, and fix the steel supports to the concrete ground by welding reinforcing bars. Hoist the rail onto the steel supports, symmetrically arranging the rail with the elbow pipe installation center line as the reference. After the rail center and span are adjusted to be qualified, weld the rail foundation to the steel supports.

[0033] In use, install the two traveling devices into the track grooves respectively. Adjust the distance between the two traveling devices according to the required elbow pipe length. Then install the connecting rod and adjust it to align with the corresponding through holes on the end beam before installing the fasteners. After the elbow pipe transport device is installed, move the transport device to the hoisting position of the crane hook in the factory. Then, hoist the elbow pipe 15 onto the transport device and transport it to the installation position by hand-operated hoist or manual pushing.

[0034] The application proposes an auxiliary transport device constructed using materials such as steel and detachable screw connections. It is assembled during use and disassembled when not in use, allowing for reuse. The overall structure is simple, easy to assemble and disassemble, low-cost, and safe and reliable. The traveling mechanism can be adjusted forward and backward according to the elbow tube length; the connecting rod only needs to connect to different holes on the end beam, making it suitable for transporting elbow tubes of varying lengths. The connecting rod is designed with a single bolt connecting to the end beam, automatically adapting to elevation deviations caused by the track reference plane, thus promoting balanced force distribution on the traveling mechanism.

[0035] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
