The pipe jacking technology is generally divided into several categories such as slurry balance, earth pressure balance and air pressure balance, among which the earth pressure balance technology is widely used due to its simple equipment and good environmental protection. The traditional earth transporting trolley is used for earth transporting in the earth pressure balance pipe jacking construction. Since the pipe diameter is small, the earth transporting trolley can only travel in one direction. However, with the progress of technology in recent years, the single-section jacking distance of pipe jacking is gradually increased, which can generally reach about one kilometer. With the increase of the single-section jacking distance, the working efficiency of the traditional earth transporting trolley cannot meet the jacking efficiency requirement, and the jacking stagnation and waiting for the earth transporting trolley to transport earth often occur in construction.

[0056] The folding process is as follows: the power oil cylinder 801 is started, generating a pushing force, which drives the driving rod 802 to push the pinion 804, thereby driving the large gear 805 to rotate, which drives the first displacement gear 807, the second displacement gear 808, the third displacement gear 809, and the fourth displacement gear 810 to rotate. At this time, the toothed structure on the fourth push rod 14 on the first side plate 708 is in engagement with the third displacement gear 809, which first displaces, driving the first side plate 708 to fold. When the first side plate 708 is folded, the third displacement gear 809 and the toothed structure of the fourth push rod 14 are disengaged, and the fourth push rod 14 no longer displaces. Then, the fourth stop rod 19 of the second side plate 710 corresponding to the fourth displacement gear 810 collides with the straight extension surface 2404 of the one-way stop rod 24 of the third push rod 13, and drives the third push rod 13 to displace, and then the fourth displacement gear 810 and the toothed structure of the third push rod 13 engage, continue to displace, until the fourth displacement gear 810 and the toothed structure of the third push rod 13 are disengaged, and the displacement is completed. The large gear 805 continues to rotate, and the end plate 704 corresponding to the first stop rod 16 and the second stop rod 17 of the first displacement gear 807 and the second displacement gear 808 rotates to collide with the stop column 1412 on the first push rod 11 and the second push rod 12, and the first displacement gear 807 and the second displacement gear 808 engage with the toothed structure of the first stop rod 16 and the second stop rod 17, respectively, to displace, until the first displacement gear 807 and the second displacement gear 808 are disengaged from the toothed structure of the first stop rod 16 and the second stop rod 17, respectively, and the displacement is completed, and the end plate 704 is completely folded.

[0057] After folding is completed, the winch 209 is started, and the lifting frame 201 is lowered. The lifting ring 202 on the lifting frame 201 is manually sleeved on the lifting lug 501 of the car 1, and the winch 29 is started in reverse to lift the second unearthing car 1. As the lifting cable 208 rises, the movable end limiter 205 rises, and finally contacts the fixed end limiter 204. At this time, the winch 209 circuit is disconnected, and the lifting system stops working.

[0058] When the first unearthing car 1 is full, the pipe pushing is temporarily stopped. The first unearthing car 1 transports the earth. The winch 209 is started, and the second unearthing car 1 is lowered to the track 3. The lifting ring 202 is removed. The folding system 8 is started, and the car hopper 7 is opened and erected. The unearthing car 1 is opened to the belt conveyor 4 below to receive the earth. After the first unearthing car 1 is unearthing, it is opened back, and the cycle is repeated.

[0059] The opening process is opposite to the folding process, wherein the first side plate 708 is "closed first and opened later", the end plate 704 is "closed later and opened first", and the second side plate 710 is "closed in the middle and opened in the middle", so that the first side plate 708 and the end plate 704 are respectively provided with a set of blocking rods and one-way stop rods corresponding to the setting, and the second side plate 710 is provided with two sets of blocking rods and one-way stop rods corresponding to the setting. Each blocking rod and one-way stop rod can realize one-way limiting.

[0060] The above embodiments are only preferred technical solutions of the present application, and should not be regarded as a limitation of the present application. The protection scope of the present application should be the technical solutions recited in the claims, including equivalent replacement solutions of the technical features recited in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present application.
