[0002] With the continuous development of tunnel engineering technology, the tunnel construction environment is becoming increasingly complex, and the construction difficulty of small-section and large-slope tunnels is particularly prominent. During the secondary lining construction of the tunnel, the top arch arc steel bar is a key load-bearing component, and its transportation and installation have always been a difficult point in the construction.

[0003] Traditional methods mostly use large flatbed transporters to assist cranes and manual handling, which is not only inefficient but also poses great safety risks.

DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical scheme and the technical effects brought about.

[0021] like Figure 1-Figure 5 As shown, a hydraulic tunnel lining arc steel bar transportation device comprises a trolley 1 and a transportation part 2; The transport part 2 includes a transport frame 21, a roller 22, a first clamping member 23, a second clamping member 24 and a bearing member 25; the first clamping member 23 is arranged at the left end of the transport frame 21, and is used to clamp the left part of the arc-shaped steel bar 3; the second clamping member 24 is arranged at the right end of the transport frame 21, and is used to clamp the right part of the arc-shaped steel bar; the bearing member 25 is arranged at the middle part of the transport frame 21, and is used to bear the middle part of the arc-shaped steel bar; the roller 22 is arranged at the bottom of the transport frame 21; The trolley 1 is arranged at the left end of the transport frame 21 to drive the transport frame 21 to move.

[0022] When using the device, first connect the trolley 1 and the transport frame 21 of the transport part 2. Since the lower end of the transport frame 21 is provided with a roller 22, it can move under the drive of the trolley 1; first move the device to the area of ​​lining arc-shaped steel bars through the trolley 1, clamp the left part of the arc-shaped steel bars with the first clamping member 23, and clamp the right part with the second clamping member 24. After clamping, the limiting is completed, and a load-bearing frame 25 is set at the lower part of the arc-shaped steel bars for auxiliary support, so as to further improve the limiting effect, so that the transport part 2 can be transported smoothly in a tunnel with a large slope.

[0023] like Figure 3As shown, as a preferred embodiment, the first clamping member 23 includes a front clamping seat 231, a rear clamping seat 232, a first clamping rod 233 and a second clamping rod 234, the front clamping seat 231 is arranged on the left side of the front frame of the transport frame 21, and the rear clamping seat 232 is arranged on the left side of the rear frame of the transport frame 21; one end of the first clamping rod 233 is connected to the lower end of the front clamping seat 231, and the other end is connected to the lower end of the rear clamping seat 232; one end of the second clamping rod 234 is hinged to the upper end of the front clamping seat 231, and the other end is connected to the upper end of the rear clamping seat 232 in an openable and closable manner. In this embodiment, when using the first clamping member 23 to clamp the arc-shaped steel bar, first open the second clamping rod 234 connected to one end of the rear clamping seat 232, and place the left end of the arc-shaped steel bar on the first clamping rod 233. Since the other end of the second clamping rod 234 is hinged to the upper end of the front clamping seat 231, the second clamping rod 234 is lowered at this time. The first clamping rod 233 and the second clamping rod 234 clamp the arc-shaped steel bar from two directions to limit the position. The arc-shaped steel bar will slide along the slope direction when transported on a slope, but will not move up and down under the limitation of the first clamping rod 233 and the second clamping rod 234, thereby ensuring the stability of transportation.

[0024] like Figure 3 As shown, as a preferred embodiment, the first clamping member 23 also includes a first sliding portion 235 and a second sliding portion 236; the first sliding portion 235 includes a track base 237 and a slider 238, the track base 237 is arranged on the left side of the front frame of the transport frame 21, the slider 238 is slidably arranged on the track base 237, and the front clamping seat 231 is arranged on the upper end of the slider 238; the second sliding portion 236 has the same structure as the first sliding portion 235, and is arranged on the left side of the rear frame of the transport frame 21, and the rear clamping seat 232 is arranged on the slider of the second sliding portion 236. In this embodiment, when transporting curved steel bars, due to the different curvatures of the curved steel bars, certain adjustments need to be made when limiting. At this time, the slider 238 is slid to slide along the track base 237. Since the front clamping seat 231 and the rear clamping seat 232 are respectively arranged on two sliders, they move with the sliders to achieve position adjustment, and can better clamp the curved steel bars.

[0025] like Figure 2 As shown, as a preferred embodiment, the second clamping member 24 has the same structure as the first clamping member 23 and is arranged on the right side of the transport frame 21. In this embodiment, the second clamping member 24 has the same structure as the first clamping member 23 and clamps the two ends of the arc-shaped steel bar together with the first clamping member 23.

[0026] like Figure 3As shown, as a preferred embodiment, the end of the first clamping rod 233 that contacts the arc-shaped steel bar is provided with a steel bar clamping groove 26. In this embodiment, the upper end of the first clamping rod 233 contacts the arc-shaped steel bar. Since many arc-shaped steel bars are put together to meet the lining construction, the steel bar clamping groove 26 is provided at the upper end of the first clamping rod 233 to enhance the connection stability of the arc-shaped steel bar.

[0027] like Figure 4 As shown, as a preferred embodiment, the bearing member 25 includes a first bearing frame 251; the first bearing frame 251 is U-shaped, including a first vertical plate 252, a horizontal plate 253 and a second vertical plate 254, the front end and the rear end of the horizontal plate 253 are respectively connected to the lower ends of the first vertical plate 252 and the second vertical plate 254, the upper end of the first vertical plate 252 is hinged to the middle part of the front frame of the transport frame 21, the upper end of the second vertical plate 254 is hinged to the middle part of the rear frame of the transport frame 21, and the end of the horizontal plate 253 that contacts the arc-shaped steel bar is provided with a steel bar groove. In this embodiment, the first bearing frame 251 is used to bear the middle part of the arc-shaped steel bar. The horizontal plate 253 is at the bottom and directly contacts the arc-shaped steel bar. A steel bar slot is provided to enhance the stability of the connection. The first vertical plate 252 and the second vertical plate 254 are provided at the front and rear ends and are hinged to the transport frame 21. When the device transports the arc-shaped steel bar into a road section with a large slope, the first vertical plate 252 and the second vertical plate 254 are tilted, so that the first vertical plate 252 and the second vertical plate 254 are in a vertical state under the action of gravity, so as to better support the arc-shaped steel bar.

[0028] like Figure 3 As shown, as a preferred embodiment, the bearing member 25 further includes a second bearing frame 255, which has the same structure as the first bearing frame 251 and is symmetrically arranged with the first bearing frame 251. In this embodiment, in addition to the first bearing frame 251, the second bearing frame 255 is also arranged, and the second bearing frame 255 and the first bearing frame 251 work together to support different sections of the arc-shaped steel bar.
