Embodiment Construction

[0019] Such as figure 1 and figure 2 As shown, it is a top view and a right side view of a small-diameter tunnel inverted arch concrete transport trolley that can quickly switch tracks in the present invention, including a vehicle frame 1, a wheel set, a steering bearing 4, a limit spring 5, a gear motor 6, and a storage battery Group 7 and Control Box 8.

[0020] The bottom of vehicle frame 1 is equipped with 4 pairs of wheel groups, and wheel group is connected with vehicle frame 1 by steering bearing 4, can guarantee that wheel group adapts to track curve to rotate when the curve section walks.

[0021] One end of the limit spring 5 is welded on the side of the wheel group, and the other end is welded on the vehicle frame 1, which can ensure that when the non-curve section is walking, the wheel group returns to normal in time under the active force of the limit spring 5.

[0022] The four pairs of wheel sets are respectively two pairs of wide-gauge wheel sets 2 and two p...

Abstract

The invention discloses a small-diameter tunnel inverted arch concrete transport trolley capable of quickly switching tracks, comprising a vehicle frame, a wheel set, a deceleration motor, a storage battery set and a control box. Four pairs of wheel sets are installed on the bottom of the vehicle frame, two pairs of wide The gauge wheel set is in contact with the inverted arch transport track and can move on the inverted arch transport track. Two pairs of narrow gauge wheel sets are in contact with the tunnel transport track and can move on the tunnel transport track. The transport trolley is in the small diameter tunnel When walking, first use two pairs of narrow-gauge wheel sets to drive to the inverted arch formwork area through the tunnel transport track, and then use two pairs of wide-gauge wheel sets to switch to the inverted arch transport track integrated with the inverted arch formwork to transport the concrete to the pouring Point pouring. The invention can realize that the tunnel inverted arch concrete transport trolley directly travels from one set of tracks to another set of tracks with different gauges, realizes fast track switching, improves concrete pouring efficiency, avoids concrete pumping construction, and reduces the risk of pipe blockage.

Description

technical field [0001] The invention relates to the technical field of tunnel concrete transportation equipment, in particular to a small-diameter tunnel inverted concrete transportation trolley capable of quickly switching tracks. Background technique [0002] In the construction of the second lining of the small-diameter long-distance full-circle tunnel, because the small-diameter and conventional-size equipment cannot enter the tunnel, it is usually necessary to lay transportation tracks in the range of the inverted arch and customize rail-type transportation equipment for material transportation; during the construction of the inverted arch, Due to the need to set up the upper sealing formwork, and the integrated track on the formwork cooperates with the rail-type lifting equipment to assist the formwork transfer, so when the concrete is poured, the concrete cannot be directly transported to the pouring surface for pouring. If pumping is used, it is very easy to cause con...
