Description

Technical Field

[0001] The utility model relates to the technical field of communication channel construction, in particular to a large-diameter shield construction hydraulic trolley support system. Background Art

[0002] The connecting channel is built at a certain distance (usually about 600 meters) between the left and right tunnels to connect the left and right tunnels. It is a humane design so that when a fire or other abnormal situation occurs in one tunnel during normal operation of the tunnel, people can be evacuated quickly and safely to the other tunnel through the connecting channel.

[0003] The earliest construction method for connecting tunnels involved reinforced ground and then excavated using a mining method to create a composite lining. This reinforcement method involved grouting and freezing. This method left the soil completely exposed during construction. If the soil froze, the reinforcement failed, or if there were dangers like quicksand, it would be extremely dangerous and could severely impact the existing tunnel. To minimize these impacts, support and reinforcement of the tunnel segments and the surrounding soil were required during shield tunneling construction to ensure safety and efficiency.

[0004] The existing shield tunnel connecting channel construction trolley uses at least one supporting device to support each segment. The large number of supporting devices used leads to high costs and is not conducive to the consistency of the supporting force on the segment.

[0005] To this end, we designed a large-diameter hydraulic trolley support system for shield construction. Utility Model Content

[0006] In order to overcome the deficiencies in the background technology, the utility model discloses a large-diameter shield construction hydraulic trolley support system.

[0007] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions:

[0008] A large-diameter shield construction hydraulic trolley support system includes a trolley body, and a plurality of top support plates arranged along its length direction are arranged at intervals along its circumference on the outer periphery of the trolley body. At least two hydraulic rods are arranged between the inner plate surface of the top support plate and the corresponding side of the trolley body to facilitate driving the top support plate to move outward to support the tunnel segment or to drive the top support plate to move inward away from the tunnel segment.

[0009] Preferably, the trolley body includes gantries spaced apart along its length and longitudinal beams connecting all the gantries, and the two longitudinal beams located at the bottom of the gantries are each provided with a plurality of walking devices spaced apart along its length.

[0010] Preferably, the traveling device comprises an isosceles wheel frame with the top end hinged to the bottom of the longitudinal beam, and traveling wheels are provided at both ends of the bottom of the isosceles wheel frame.

[0011] Preferably, a communication channel construction reserved opening is provided at a middle position along the length direction of one side of the trolley body, so that the communication channel construction reserved opening and the inner cavity of the trolley body form a communication channel construction channel.

[0012] Preferably, a retractable workbench is provided at a position in the inner cavity of the trolley body corresponding to the reserved opening for construction of the communication channel.

[0013] Preferably, slide rails extending toward the inner cavity of the trolley body are provided on both sides of the reserved opening for construction of the communication channel, and a workbench is movably connected between the two slide rails along their length direction.

[0014] Preferably, the workbench and the slide rail are both provided with a slide groove on the opposite side, and the slide groove cavity is provided with a movable structure movably connected to the workbench and the slide rail.

[0015] Preferably, the movable structure comprises two movable parts spaced apart along the length direction of the slide slot, and a spring telescopic rod is provided between the two movable parts.

[0016] Preferably, the movable part includes a wheel axle whose middle portion is correspondingly connected to one end of the spring telescopic rod, and both shaft ends of the wheel axle are provided with pulleys, and the two pulleys are respectively connected to the workbench and the slide rail in a rolling manner.

[0017] Preferably, the arc diameter of the outer plate surface of the top support plate is not larger than the arc diameter of the tunnel, the outer plate surface of the top support plate is provided with a flexible layer, and the thickness of the flexible layer gradually increases from the inside to the outside along the width direction of the outer plate surface of the top support plate.

[0018] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0019] 1. The setting of the top support plate can uniformly support a row of segments in the length direction of the trolley body through a top support plate, which can effectively ensure the consistency of the supporting force on the segments, and can also effectively reduce the number of hydraulic rods used and reduce the production cost;

[0020] 2. The setting of the isosceles wheel frame and the running wheel can make the running wheel easily cross the uneven area on the laid rail through the rotation of the isosceles wheel frame when the trolley body is moved, and can effectively reduce the bumping amplitude of the trolley body;

[0021] 3. The setting of the movable structure can increase the distance between the two movable parts as much as possible through the spring telescopic rod, thereby improving the stability of the workbench after it is unfolded, thereby improving the safety of construction workers;

[0022] 4. The specific structural setting of the top support plate and the flexible layer can support the pipe segment through the middle of the flexible layer in the middle of the top support plate when supporting the pipe segment. Since the thickness of the flexible layer gradually increases from the inside to the outside, the side of the top support plate can also effectively support the pipe segment through the side of the flexible layer, so that the combination of the top support plate and the flexible layer can adapt well to pipe segments of different diameters, that is, it can adapt to the supporting operation of pipe segments in tunnels of different sizes.
