[0001] The utility model relates to the field of shield construction of underground tunnels, in particular to a device for transporting muck and segments under space constraints. Background Art

[0002] With the wide application of shield tunneling method in the high-quality development of fields such as municipal transportation, water conservancy and hydropower, and urban subways in China, shield technology has become increasingly mature and perfect, and has gradually become the first choice for urban underground tunnel construction. The starting of a shield machine can be roughly divided into integral starting and split starting. When the shield machine is under the condition of limited site, split starting technology is often used. In split starting, when the main machine and the double-track beam cannot start at the same time, it will bring difficulties in transporting muck and segments. Especially, how to transport the segments to a suitable position for the segment erector to grab is a particularly difficult problem. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a device for transporting muck and segments under space constraints, which can solve the problem of inconvenient transportation of muck and segments caused by the inability of the double-track beam of the shield machine to start simultaneously with the main machine under space constraints, and improve the construction efficiency under this working condition.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0005] A device for transporting muck and segments under space constraints includes a bearing plate. Walking wheels are installed at the lower end of the bearing plate. A groove is arranged at the upper end of the bearing plate. The planes on the left and right of the groove on the bearing plate support a slag bucket. A rotating platform is installed in the groove on the bearing plate, and the rotating platform is driven to rotate by a rotating motor.

[0006] There are multiple groups of the walking wheels, and one or more groups of the walking wheels are driven to walk by a driving motor.

[0007] Pulling ears are installed at the front and back of the bearing plate.

[0008] The bearing plate is an integrally bent plate. The horizontal parts on both sides of the bearing plate are high, the middle horizontal part is low, and the middle horizontal part and the horizontal parts on both sides are smoothly transitioned through inclined surfaces.

[0009] A plurality of foot supports are arranged on the side of the slag bucket, and the foot supports are arranged in a vertical straight line or a vertical staggered arrangement.

[0010] The rotating platform includes a support plate. The support plate is fixed on the bearing plate.

[0011] The support plate includes support beams arranged at intervals at the lower end. An interval for installing the rotating motor is formed between the support beams, and a plate body is fixed above the support beams.

[0012] Blocking members are fixed on the upper end surface of the support plate and the lower end surface of the rotating plate. The upper and lower blocking members are on the same circle in the horizontal projection plane and are arranged in a staggered manner.

[0013] The blocking member includes a blocking block and a buffer sheet, and the buffer sheet is located on one or more sides of the blocking block.

[0014] The included angle formed by the connection lines of the upper and lower blocking members and the center of the circle matches the angle that the rotating table needs to rotate.

[0015] The utility model provides a muck and segment transportation device under limited space, and has the following technical effects: through a muck hopper, a bearing plate and traveling wheels, etc., shield muck can be transported out of the tunnel. At the same time, a rotating table is arranged on the bearing plate.

[0019] Figure 3 is a schematic diagram of the mechanism of the rotating table of the utility model.

[0020] Figure 4 is a usage flow chart of the utility model.

[0021] In the figure: traveling wheel 1, driving motor 2, bearing plate 3, muck hopper 4, rotating table 5, rotating motor 6, lug 31, foot support 41, support plate 51, rotating plate 52, rotating bearing 53, supporting device 54, rubber 5111, small steel block 5112. Detailed Embodiments

[0022] Such as Figure 1As shown in the figure, a muck and segment conveying device under space constraints includes walking wheels 1, drive motors 2, a bearing plate 3, a muck hopper 4, a rotating table 5, and a rotating motor 6. The number of the walking wheels 1 is several, which is set according to the actual situation. The wheel frames of the walking wheels 1 are welded under the bearing plate 3, and the output end of the drive motor 2 is connected to the center of the rollers of the walking wheels 1 to provide walking power for the whole device. The number of the drive motors 2 can be one group, or multiple groups can be freely selected or not set according to the actual situation. The bearing plate 3 is integrally in a "concave" shape, with higher sides and lower middle. The two sides of the bearing plate 3 provide a support platform for the muck hopper 4. The rotating table 5 is located in the middle of the bearing plate 3, and the rotating motor 6 is located under the rotating table 5. The rotating motor 6 provides radial power for the rotating table 5 to drive the rotating table 5 to rotate.

[0023] As Figure 2 shown, the bearing plate 3 is integrally in a "concave" shape, with higher sides and lower middle. Pulling ears 31 are provided at both ends of the bearing plate 3. The pulling ears 31 can be used to connect multiple such devices to each other, and at the same time, a winch or a shield battery car can be connected through the pulling ears. When the drive motor 2 is damaged or lacks power, the winch or the shield battery car provides power for the device, or in some specific situations where the drive motor 2 is not suitable, the pulling ears can directly provide power for the whole device;

[0024] When the device discharges muck, the muck hopper 4 is horizontally placed on the bearing plate 3. The muck hopper 4 is integrally in a trapezoidal shape and hollow. A number of footrests 41 are provided on one side of the muck hopper 4. The footrests 41 facilitate construction workers to step on and check the situation inside the muck hopper 4. The footrests 41 can be arranged vertically and perpendicularly or vertically and staggeredly. Generally, when the footrests 41 are arranged vertically and perpendicularly, the upper footrests are smaller than the lower footrests to avoid mutual influence between the two when people use them.

[0025] Referring to Figure 3 , the rotating table 5 is located in the middle above the bearing plate 3 and is composed of a support plate 51, a rotating plate 52, a rotating bearing 53, and a supporting device 54. The support plate 51 is welded by H-shaped steel and Q235 steel plates, and its overall height can be freely adjusted according to the actual situation. The supporting device 54 is made of non-rigid materials such as wood and rubber to prevent damage to the outer facade of the segment during the transportation of the segment. The supporting device 54 is fixed on the rotating plate 52, and the rotating plate 52 is driven to rotate by the rotating motor 6. The upper end surface of the rotating table 5 is slightly lower than or equal to the upper horizontal planes on the left and right sides of the bearing plate 3, which is convenient for placing the muck hopper 4.

[0026] On the upper end surface of the support plate 51 and the lower end surface of the rotating plate 52, a number of stoppers 511 are welded respectively. The stopper 511 is composed of a stopper block 5111 and a buffer sheet 5112. The stopper block 5111 is a steel block, and the buffer sheet 5112 is rubber. The rubber can play a buffering effect when two stoppers 511 touch each other, avoiding violent vibration of the overall device. After the upper and lower stoppers 511 are arranged, the rotation angle of the rotating plate 52 relative to the rotation can be restricted. For example: in this device, after the segment is transported under the segment erector, in order to facilitate its grasping (suction) of the segment, the segment needs to be rotated 90° in a certain direction. One stopper 511 can be arranged in the front and back directions on the support plate 51 respectively, and one stopper 511 can be arranged in the left and right directions on the rotating plate 52 respectively. The four stoppers 511 are all on the same circle in the horizontal projection plane. Of course, one stopper 511 can also be arranged on the support plate 51 and one stopper 511 can be arranged on the rotating plate 52. The two stoppers 511 are all on the same circle in the horizontal projection plane and the included angle formed by the connecting lines of the two and the center of the circle is 90°. By rotating in one direction, a 90° rotation can also be achieved.

[0027] When other angles need to be rotated, other positions can also be set, and the principle is the same.

[0028] Working principle and process:

[0029] S1. When it is necessary to transport muck, lift the muck hopper 4 and place it on the bearing plate 3.

[0030] S2. Start the driving motor 2 and drive the device to the muck outlet of the shield main machine.

[0031] S3. After the muck hopper 4 is loaded with a certain amount of muck, the whole device retreats to a suitable position.

[0032] S4. Lift the muck hopper 4 through the equipment and unload the muck.

[0033] S5. Repeat S1 - S4 until the propulsion amount of the shield machine meets the assembly of one segment.

[0034] S6. Lift the segment and place it on the rotating table 5, and make the segment fit with the supporting device 54.

[0035] S7. Drive the whole device to the segment erector.

[0036] S8. The rotating motor 6 drives the rotating plate 53, and the segment rotates 90° with the rotating plate 53, and the segment erector grasps (suctions) the segment.

[0037] S9. The whole device retreats to a suitable position.

[0038] S10. Repeat S6 - S10 until the assembly of the whole ring of segments is completed.

[0039] In S2, existing external devices such as a hoist and a shield battery car can also be used to drive through the pull ear 31.
