Description

Technical Field

[0001] This utility model relates to the field of tailwater pipe transportation technology, and in particular to a tailwater pipe transportation trolley. Background Technology

[0002] In the installation of the tailrace pipe of a hydropower station, the transportation and precise placement of the tailrace pipe are crucial. There are two traditional construction methods. One is to install a transport track on the tailrace pipe support, install a sliding shoe on the bottom of the tailrace pipe, apply lubricant between the track and the sliding shoe, and drag it by a hand-operated hoist. In this method, because the track and the support are supported at a point, the track will deform under the weight of the tailrace pipe, and the sliding friction is large. This method requires a large number of construction workers and has low construction efficiency and safety. The second method is to install a transport track under the tailrace support, build a simple flatbed trolley, and place the tailrace pipe on the flatbed trolley for transportation.

[0003] However, due to the different horizontal and vertical spacing of the bottom support legs of different pipe sections, a large amount of wooden blocks need to be placed between the flatbed trolley and the tailwater pipe for leveling, and the flatbed anchors at the bottom of the tailwater pipe need to be staggered, which greatly reduces the stability of the support.

[0004] Therefore, a tailrace pipe transport trolley is proposed. Utility Model Content

[0005] To address the issue that the different lateral and longitudinal spacing of the bottom support legs of different tailpipe sections necessitates the use of a large amount of wooden blocks for leveling between the flatbed trolley and the tailpipe, and the need to offset the flatbed anchors at the bottom of the tailpipe, which significantly reduces the stability of the support, this utility model provides a tailpipe transport trolley.

[0006] This utility model provides a tailrace pipe transport trolley, which adopts the following technical solution:

[0007] A tailpipe transport trolley includes guide rails, two of which are provided. A transport vehicle is provided on the upper surface of the two guide rails.

[0012] By adopting the above technical solution, the movement of the mobile seat can be effectively achieved, and the positioning of the mobile seat can also be achieved.

[0013] Optionally, a fixed seat is provided on one side of the upper surface of the mounting plate, an electric telescopic rod is provided on one side of the fixed seat, and a movable seat is provided at the other end of the electric telescopic rod.

[0014] By adopting the above technical solution, the distance between the fixed seat and the movable seat can be effectively adjusted.

[0015] Optionally, the bottom of the movable seat is provided with a limiting plate, the two sides of the limiting plate are trapezoidal in cross-section, the bottom of the movable seat is embedded in the second sliding groove, and the limiting plate is adapted to the positioning plate.

[0016] By adopting the above technical solution, the positioning effect of the mobile seat can be effectively achieved.

[0017] Optionally, a support plate is provided between the two mounting plates, and the support plate is provided with a concave arc surface.

[0018] By adopting the above technical solution, it is possible to effectively fit the outer wall of the tailwater pipe, making the fit between the two more tight.

[0019] Optionally, a groove is formed on one side of the tray, and a connecting plate is embedded inside the groove. The diameter of the connecting plate is smaller than the diameter of the tray, and the shape of the connecting plate is consistent with the shape of the tray.

[0020] By adopting the above technical solution, the outer wall of the tailwater pipe can be effectively supported, thus preventing the outer wall of the tailwater pipe from collapsing.

[0021] Optionally, the top of both the fixed base and the movable base is provided with a concave arc surface.

[0022] By adopting the above technical solution, the lifting effect on the tailwater pipe can be further achieved.

[0023] In summary, this utility model has the following beneficial effects:

The top of the fixed seat and the movable seat is set with an inwardly concave arc surface, which can contact the outer wall of the tailwater pipe, making the fit between the two more tight. At the same time, it avoids the formation of dead angles between the two, which would cause the tailwater pipe to shake. When transporting tailwater pipes of different specifications, the electric slider is controlled by the control panel to slide inside the slide groove two, so that the distance between the fixed seat and the movable seat is the same as the diameter of the tailwater pipe or located at one-third of the outer wall of the tailwater pipe. When the movable seat moves, the positioning plate and the limiting plate contact each other, and the two are engaged, thereby positioning the movable seat and preventing the movable seat from shifting.

[0032] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please refer to Figure 1-4 A tailwater pipe transport trolley includes a guide rail 1, two guide rails 1 are provided, a transport vehicle 2 is provided on the upper surface of the two guide rails 1, six rollers 201 are provided at the bottom of the transport vehicle 2, a locking mechanism 202 is provided on one side of the rollers 201, a control panel 203 is provided on one side of the transport vehicle 2, and a battery charging port 204 is provided on one side of the control panel 203 and away from the control panel 203.

[0034] The upper surface of the transport vehicle 2 has two slide grooves 205, and electric sliders 206 are provided on both sides inside the two slide grooves 205. The top of the two electric sliders 206 is provided with a lifting platform 207.

[0035] When the transport vehicle 2 moves on the surfaces of the two guide rails 1, it moves via the rollers 201 at the bottom of the transport vehicle 2. When it moves to the designated position, the locking mechanism 202 is controlled by the control panel 203. At this time, the locking mechanism 202 locks the rollers 201, so that the transport vehicle 2 is in the designated position and will not deviate.

[0036] Reference Figure 2 and Figure 3 The top of the lifting platform 207 is provided with an installation plate 3. A slide groove 301 is opened at one half of the upper surface of the installation plate 3. Positioning plates 302 are arranged horizontally at equal intervals on the inner wall of the slide groove 301. The cross-section of the positioning plates 302 is trapezoidal.

[0037] A fixed seat 303 is provided on one side of the upper surface of the mounting plate 3, an electric telescopic rod 304 is provided on one side of the fixed seat 303, and a movable seat 305 is provided at the other end of the electric telescopic rod 304.

[0038] The bottom of the movable seat 305 is provided with a limiting plate 306. The two sides of the limiting plate 306 are trapezoidal in cross-section. The bottom of the movable seat 305 is embedded in the sliding groove 301. The limiting plate 306 is adapted to the positioning plate 302.

[0039] The tops of both the fixed base 303 and the movable base 305 are concave arc surfaces;

[0040] The tailwater pipe is placed on top of the fixed base 303 and the movable base 305. The top of the fixed base 303 and the movable base 305 are set with concave arc surfaces, which can contact the outer wall of the tailwater pipe, making the two fit more tightly and avoiding the generation of dead corners between them, which would cause the tailwater pipe to shake.

[0041] Secondly, when transporting tailwater pipes of different specifications, the electric slider 206 is controlled by the control panel 203 to slide inside the slide groove 301, so that the distance between the fixed seat 303 and the movable seat 305 is the same as the diameter of the tailwater pipe or located at one-third of the outer wall of the tailwater pipe. When the movable seat 305 moves, the positioning plate 302 and the limiting plate 306 come into contact and engage, thereby positioning the movable seat 305 and preventing the movable seat 305 from shifting.

[0042] Furthermore, when the movable seat 305 moves, the electric telescopic rod 304 also extends and retracts accordingly. When the movable seat 305 moves to the designated position, the electric telescopic rod 304 stops working, thereby providing support between the movable seat 305 and the fixed seat 303 and preventing the movable seat 305 from moving.

[0043] Reference Figure 3 and Figure 4 A support plate 4 is provided between the two mounting plates 3, and the support plate 4 is set with an inwardly concave arc surface;

[0044] A groove 401 is formed on one side of the tray 4, and a connecting plate 402 is embedded inside the groove 401. The diameter of the connecting plate 402 is smaller than the diameter of the tray 4, and the shape of the connecting plate 402 is the same as the shape of the tray 4.

[0045] When the tailwater pipe is placed on top of the fixed seat 303 and the movable seat 305, the outer wall of the tailwater pipe contacts the upper surface of the support plate 4. The upper surface of the support plate 4 is set with an inwardly concave arc surface, which can fit tightly with the outer wall of the tailwater pipe, thereby preventing the outer wall of the tailwater pipe from collapsing.

[0046] Secondly, when the movable seat 305 is sliding and adjusting, the connecting plate 402 also extends and retracts accordingly, so that the support plate 4 and the connecting plate 402 can always be in contact with the outer wall of the tailwater pipe, further preventing the outer wall of the tailwater pipe from collapsing.

[0047] The implementation principle of this utility model is as follows: First, when the transport vehicle 2 moves on the surfaces of the two guide rails 1, it moves via the rollers 201 at the bottom of the transport vehicle 2. When it moves to the designated position, the locking mechanism 202 is controlled by the control panel 203. At this time, the locking mechanism 202 locks the rollers 201, so that the transport vehicle 2 will not deviate from the designated position. The tailwater pipe is placed on the top of the fixed seat 303 and the movable seat 305. The top of the fixed seat 303 and the movable seat 305 is set with an inwardly concave arc surface, which can contact the outer wall of the tailwater pipe, making the fit between the two more tight. At the same time, it avoids the formation of dead angles between the two, which would cause the tailwater pipe to shake. When the tailwater pipe is placed on the top of the fixed seat 303 and the movable seat 305, the outer wall of the tailwater pipe is in contact with the upper surface of the support plate 4. The upper surface of the support plate 4 is set with an inwardly concave arc surface, which can fit tightly with the outer wall of the tailwater pipe.
