Embodiment 1

[0028] Example 1: Such as figure 1 As shown, a segment transportation system suitable for small curve turns of a shield machine includes a single beam crane system 3, such as image 3 As shown, the crane beam of the single beam crane system 3 includes a fixed section beam 7 and a floating section beam 8, such as figure 2 As shown, the fixed section beam 7 is fixed on the first trolley 1, the floating section beam 8 is suspended on the second trolley 2, and the fixed section beam 7 and the floating section beam 8 are hinged by a pin to make floating The segment beam 8 can move horizontally with the No. 1 trolley 1 to meet the needs of the small curve turning construction of the shield machine; the front of the No. 1 trolley 1 is equipped with a segment transition platform 4 for storing and transferring segments 10, and Prevent the marshalling trolley from slipping. The No. 1 trolley 1 is hinged with an equipment bridge 5 through a pin shaft to avoid blocking the left and right m...

Embodiment 2

[0033] Example 2: A segment transportation system suitable for small curve turns of a shield machine, such as figure 2 As shown, the track chain I302 is disconnected at the connection between the lower part of the fixed section beam 7 and the floating section beam 8, and the disconnection of the track chain I302 is connected by a movable chain 9. When the shield machine is turning or tunneling up and down, the number one is given Trolley 1 and No. 2 trolley 2 have greater steering freedom to meet the needs of small curve turning and up and down slope conditions. The front part of the track chain I302 is fixed at the lower part of the fixed section beam 7, and the rear part of the track chain I302 is fixed at the lower part of the floating section beam 8, to prevent the tube crane driving device I306 from swinging from side to side when moving on the track chain I302 , Other structures and construction methods are the same as in Example 1.

Embodiment 3

[0034] Example 3: A tube segment transportation system suitable for a small curve turning of a shield machine, such as Figure 4 As shown, the hoist beam of the single-beam hoist system 3 is provided with a buffer bracket I304, and the buffer bracket I304 is provided with a polyurethane buffer I305, and the polyurethane buffer I305 cooperates with the segment hoist driving device I306. The polyurethane buffer uses the microporous bubble structure of the polyurethane material to absorb energy and buffer. It is equivalent to a spring with multi-airbag damping during the impact process. Therefore, the polyurethane buffer I306 has a certain elastic deformation ability to cushion Protect the role of crane I to prevent crane I from rushing out of the crane beam and causing accidents. The power transmission port of the segment crane driving device I306 is connected with the cable I307, such as Figure 7 As shown, the other end of the cable I307 is connected to the hoist control cabinet...

Abstract

The invention discloses a segment transport system suitable for a small curved turn of a shield machine. The segment transport system suitable for the small curved turn of the shield machine solves the problem that the existing segment transport system is difficult to meet the small curve turn of the shield machine. The segment transport system comprises a single beam crane system. The crane beamof the single beam crane system comprises a fixed segment beam and a floating segment beam, the fixed segment beam is fixed on the first trolley, and the floating segment beam is suspended on the second segment. On the trolley, the fixed segment beam and the floating segment beam are hinged. A segment transition platform is arranged on the front portion of a first trolley, and the first trolley ishinged to an equipment bridge, a second piece crane driving device is installed on the equipment bridge. A draging oil cylinder is arranged on the front portion of the equipment bridge, and the equipment bridge is connected with a segment assembly machine through the tractor oil cylinder. The fixed segment-beam and floating segment-beam adopt the mode of hinge connection, and meanwhile the segment assembly machine is connected with the equipment bridge by the dragging oil cylinder, so as to jointly meet the construction requirements of the small curve turn of the shield tunneling machine.

Description

Technical field [0001] The invention relates to a tunnel segment transportation system, in particular to a segment transportation system suitable for a small curve turning of a shield machine. Background technique [0002] The structure of the segment transport system equipped on the existing shield includes a single beam crane system, equipment bridge, segment transport trolley, and segment assembly machine. The working process is to transport the segment crane on the marshalling train to the segment transport trolley through the single beam crane system. The segment transport trolley transports the segments through the bottom of the equipment bridge to the position where the segment assembly machine grabs. The piece assembly machine picks up the pipe pieces to complete the assembly. [0003] However, because the segment transport trolley occupies the tunnel assembly area space, it is inconvenient for personnel to pass, and it is difficult to clean up the belt when the slag is dr...
