Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering construction, in particular to a movable steel pipe transportation track device for construction in a tunnel chamber. Background Technique

[0002] At present, when installing steel pipes in a tunnel chamber and the installation position of the steel pipes is more than one meter above the ground, the steel pipes cannot be unloaded by the conventional sky anchor in the chamber. For the installation of chamber steel pipes with such elevation differences, a truck crane is usually used for unloading. The truck crane is used to hoist the penstock into place, but there are the following problems when using a truck crane for hoisting:

[0003] 1. When using a truck crane to unload and hoist in the tunnel chamber, the boom of the crane is prone to collide with the tunnel chamber wall, posing a great safety hazard.

[0004] 2. When using a truck crane to hoist steel pipes, the equipment occupancy rate is large and the cost is high.

[0005] 3. During the hoisting process of the truck crane, the penstock shakes greatly, posing a great construction safety risk.

The bottom end of the vertical rod 42 is threadedly connected with a telescopic base 5. The telescopic base 5 is installed with universal wheels 6 for the movement of the device. The two track beams 2 are detachably connected by bolts with a number of transverse connecting beams 7. The front part of the track beam 2 is also provided with a column 12 for extending support.

[0029] In this embodiment, the front end of the track beam 2 is provided with a track beam horizontal lifting lug 21 for on-site fixation to fix the front end of the device at the construction site.

[0030] The universal wheel 6 is connected to the base 5 through a wheel frame 8 and a wheel pin shaft 9 provided.

[0031] This embodiment also includes a track beam pin shaft 10. The track beam horizontal lifting lug 21 is provided with a pin hole. The track beam 2 is fixed on-site by inserting the track beam pin shaft 10 anchored to the on-site structure through the pin hole. The track beam 2 can rotate along the track beam pin shaft 10 to create a lifting operation space at the rear end.

[0032] The track beam 2 is provided with a track beam vertical lifting lug 22 at the connection with the connecting beam 7. The connecting beam 7 is connected to the track beam vertical lifting lug 22 by bolts.

[0033] The triangular support frame 3 includes a vertical support 32, a horizontal base 33 and two inclined supports (31) connected to each other. The angles between the two inclined supports 31 and the vertical support 32 are both 30 degrees.

[0034] The vertical rod 42 is made of a steel pipe and is provided with an internal thread at the bottom for threaded connection with the telescopic base 5. The cross bar 41 and the vertical rod 42 are connected by welding.

[0035] Each track beam 2 is provided with at least two groups of triangular support frames 3 to increase the structural strength and stability of the device.

[0038] Implementation process:

[0039] The construction process of steel pipe installation in a large pumped-storage power station is described below.

[0040] At an appropriate position on the construction site, sky anchors need to be installed first. For the stepped structure 11 cast on-site, move the movable steel pipe transportation track device to the corresponding position. Place the front end of the track 1 horizontally on the stepped structure 11, place the track beam 2 on the lower-level step, and vertically open two holes on the lower-level step of the stepped structure 11 according to the gauge of the steel pipe installation railcar. Insert the track beam pin 10 through the pin hole opened in the horizontal lifting ear 21 of the track beam into the holes for on-site fixation at the front end. After installing and fixing the front ends of the two track beams 2, do not install the connecting beam 7 first. Screw out the telescopic base 5 so that the universal wheel 6 is lower than the horizontal base 33 downward, and it is supported by the transverse support frame 4.

[0041] Rotate the two track beams 2 along the track beam pin 10 through the universal wheel 6 to bring the rear ends closer, making the two tracks 1 in a "V" shape, creating a hoisting operation space at the rear end of the device, and backing the trailer for transporting the steel pipe to the sky anchor unloading position; after the steel pipe transportation trailer reverses to the unloading position at the rear end of the device, vertically lift the steel pipe to hover in the air with the sky anchor, move the trailer away, and then move the rear end of the track beam 2 through the universal wheel 6. Unfold along the tunnel chamber from the position where the steel pipe hovers in the air so that the track 1 is in an "II" shape and maintain the gauge. By connecting and installing the entire connecting beam 7 on the vertical lifting ears 22 of the two track beams 2, as Figure 5 shown, the merging of the two tracks 1 is completed.

[0042] The steel pipe installation railcar is installed on the track 1 and moved to directly below the hovering steel pipe. The steel pipe is lifted onto the steel pipe installation railcar by the sky anchor, and then the steel pipe is transported to the installation site for construction by the steel pipe installation railcar.

[0043] After the pipeline construction is completed, first remove the connecting beam 7, then remove the track beam pin 10 to separate from the stepped structure 11, and then the track device can be removed for subsequent construction.

[0044] During the entire hoisting process of lifting the steel pipe with the sky anchor and hoisting the steel pipe onto the steel pipe installation railcar with the sky anchor, the steel pipe has a vertical displacement, effectively avoiding the lateral sway of the steel pipe, improving the stability and safety of the steel pipe hoisting process, and the device has high operation stability and safety; the steel pipe is smoothly transported by the steel pipe installation railcar moving on the track 1, with high construction efficiency, low cost, and high safety.
