Description

TECHNICAL FIELD

[0001] The utility model relates to a pipe jacking machine mudstone transportation field, especially in a pipe jacking machine double -channel mudstone transportation mechanism. BACKGROUND

[0002] In the pipe jacking machine construction process, the transportation of mudstone is indeed a vital link. The traditional single-channel transportation mechanism faces many challenges in practical application and is difficult to meet the needs of modern pipe jacking machine efficient and continuous construction.

[0003] When the pipe jacking machine is excavating underground, a large amount of mudstone will be produced. These mudstones need to be discharged in time and efficiently to ensure the smooth progress of construction and the stability of the tunnel. However, the existing single-channel transportation mechanism has obvious limitations in design. When a full load mud car is removed and replaced with an empty one, there is a significant waiting time in this process. During the waiting period, the mudstone produced by the pipe jacking machine may overflow in small amounts, which not only affects the construction progress, but also may have adverse effects on the safety and environment of the construction site.

A rotating shaft 7 is provided at the bottom of the feed bin 6. The rotating shaft 7 is driven by a motor. A left baffle 8 and a right baffle 9 are connected to both sides of the rotating shaft 7.

[0022] The trolley transport track 3 consists of four sets, with a first trolley 10 and a second trolley 11 respectively on the trolley transport track 3. The first trolley 10 and the second trolley 11 are provided with inlets at their tops. The adjacent inner side plates of the first trolley 10 and the second trolley 11 are located directly below the rotating shaft 7.

[0023] like Figure 1As shown, the outer side plates of the first trolley 10 and the second trolley 11 are higher than the inner side plates of the first trolley 10 and the second trolley 11, and gaps are left between the outer side plates of the first trolley 10 and the second trolley 11 and the top of the moving frame 4, so as to ensure smooth movement of the trolley on the track 3 and avoid interference with the frame.

[0024] As shown in the drawings, Figure 1 As shown, the end of the left baffle 8 and the right baffle 9 is provided with a contact plate 12, the inner side of the contact plate 12 is provided with a rubber layer, and the contact plate is in contact with the outer vertical surface of the feeding bin; the contact plate and the outer wall of the feeding bin are protected, and an approach switch can be arranged in the area to realize intelligent control.

[0025] As shown in the drawings, Figure 1 As shown, when the left baffle 8 is in contact with the left discharge port 601, the lower edge of the left discharge port 601 is not in contact with the left baffle 8, leaving a gap; when the right baffle 9 is in contact with the right discharge port 602, the lower edge of the right discharge port 602 is not in contact with the right baffle 9, leaving a gap, so as to ensure that a certain gap is left between the discharge port and the baffle, and to avoid the mud and stones from being stuck in the area, causing damage to the baffle or the feeding port.

The bottom of the feeding bin is provided with a rotating shaft driven by a motor, and the left baffle and the right baffle are connected to the two sides of the rotating shaft. The left and right baffles can rotate to control the flow direction of the mud. When it is needed to discharge to the left side, the rotating shaft drives the right baffle to rotate to be in contact with the right vertical surface of the feeding bin, so as to ensure that the mud can flow smoothly into the left side, at this time, the first trolley receives the mud; similarly, when it is needed to discharge to the right side, the rotating shaft drives the left baffle to rotate to be in contact with the left vertical surface of the feeding bin, and the mud flows into the second trolley. The first trolley and the second trolley can completely receive the mud flowing out of the feeding bin, and efficient switching of the double-channel mud transportation is realized.
