Description

Technical Field

[0001] The utility model relates to a film feeder, in particular to a film feeder which can avoid jamming during transportation. Background Art

[0002] A shield machine is a tunnel boring machine that uses the shield method. When using the shield method for construction, it is necessary to construct (lay) shield segments while excavating. Currently, the industry usually uses segment feeders to transport shield segments.

[0003] The existing segment feeder includes a base frame and a sliding frame of the same length. The sliding frame can slide forward and backward on the base frame to transport the shield segments directly from the end of the crane to the grabbing position of the assembly machine.

[0004] Although this type of film feeder can greatly improve the work efficiency of construction, it still has the following defects:

[0005] 1. Since the lengths of the base frame and the sliding frame are basically the same, a large cantilever is formed when the slide frame of the feeder carries the shield segments forward. After long-term repeated work, the steel structure of the area where the shield segments are placed in front of the sliding frame is plastically deformed and bent downward. When the sliding frame retracts backward, there is a jam between the bent part and the fixed frame.

[0006] 2. After the sliding frame is deformed, even if it can be retracted, when it extends forward to carry the second shield segment, the bent part will still get stuck with the fixed frame. At this time, the jam is more serious than when the sliding frame is retracted. If the on-site feeding machine's moving cylinder capacity is insufficient, it will cause the machine to get stuck on site.

[0007] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field. Summary of the invention

[0008] The utility model aims to overcome the disadvantage of the prior art that a sliding frame is easily deformed and causes jamming, and provides a tablet feeding machine with a sliding frame that is not easily deformed and avoids transport jamming.

[0009] To achieve the above objectives, the technical solution of the utility model is:

[0010] A film feeder that avoids jamming during transportation, the film feeder comprising: a base frame and a sliding frame;

[0011] A slideway is arranged in the middle of the base frame, a sliding frame is slidably arranged on the slideway, the length of the base frame is greater than the length of the sliding frame, and the sliding frame is used to transport shield segments.

[0012] Both ends of the slideway are arranged on the base frame 1, 1.25 times the length of the shield segment is L, and the length of the slideway is greater than or equal to the sum of the length of the sliding frame and L.

[0013] A slide rail is respectively arranged on both sides of the base frame, and the two slide rails are respectively arranged on both sides of the slideway, and the two slide rails are arranged parallel to the slideway.

[0014] The top of the slide rail is an inclined surface matched with the outer curved surface of the shield segment, and the top of the sliding frame is an inner curved surface matched with the outer curved surface of the shield segment.

[0015] A plurality of supporting rollers are evenly arranged on the top of the base frame along both sides of the slideway, the tops of the plurality of supporting rollers are in contact with the bottoms of the shield segments, and the plurality of supporting rollers are used to support the shield segments.

[0016] A limit frame is arranged on each side of the base frame, and the two limit frames are symmetrically arranged arc structures. The inner arc surfaces of the limit frames are arranged opposite to each other, and the tops of the two limit frames are fixedly connected to the connecting bridge of the shield machine. A limit roller is arranged in the middle of the limit frame, and the limit roller cooperates with the side wall of the shield segment.

[0017] The sliding frame is driven by a power device to slide on the slideway.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model provides a sheet feeding machine that avoids jamming during transportation, including a base frame and a sliding frame. A slideway is provided in the middle of the base frame, and both ends of the slideway are provided on the base frame. The sliding frame is slidably provided on the slideway, and the top of the sliding frame matches the outer arc surface of the shield segment. At the same time, the length of the slideway is greater than or equal to the sum of the length of the sliding frame and 1.25 times the length of the shield segment, so that the sliding frame of the sheet feeding machine will not leave the top of the base frame to form a cantilever during the sheet feeding process and when receiving the shield segment, so that the sliding frame is evenly stressed, not easily deformed, and runs smoothly. Therefore, the design can prevent the sliding frame from deforming and jamming by continuously supporting the sliding frame during the sheet feeding process and when receiving the shield segment through the base frame, thereby effectively improving the reliability of the sheet feeding machine.

[0020] 2. In the utility model, a sheet feeder that avoids transportation jams is provided with a slide rail parallel to the slideway on both sides of the base frame, and the top of the slide rail is an inclined surface that matches the shield segment. The inclined surface can limit the shield segment in the horizontal direction, so that the shield segment is not easy to deviate during transportation. Therefore, the design can limit the shield segment through the slide rail to prevent the shield segment from deviating.

In the utility model, a sheet feeding machine that avoids jamming during transportation is provided with a plurality of support rollers evenly arranged on the top of the base frame along both sides of the slideway, and a limit frame is arranged on each side of the base frame. The two limit frames are symmetrically arranged arc structures, and the inner arc surfaces of the limit frames are arranged oppositely. A limit roller is arranged in the middle of the limit frame, and the limit roller cooperates with the side wall of the shield segment. The support roller and the limit roller make the shield segment slide and cooperate with the base frame during transportation. Therefore, this design can support the rollers and the limit rollers to make the shield segment slide and cooperate with the base frame during transportation, effectively improving the smoothness of the sheet feeding operation.
