Description

Technical Field

[0001] The invention relates to a civil engineering device, in particular to a high-efficiency shield slag and rock automatic separation device. Background Art

[0002] During shield construction, the effective separation of slag and rock is an important part of ensuring excavation efficiency and construction safety. Traditional shield slag handling systems mostly rely on simple belt conveyor transportation and subsequent manual screening, which has many disadvantages. First, manual screening is not only inefficient, but also has a harsh working environment, posing a serious threat to the health of workers. Secondly, large pieces of rock can easily damage the equipment during belt conveyor transportation, resulting in frequent downtime for maintenance and increased construction costs. In addition, although some existing shield slag handling devices attempt to achieve automated separation, they are often complex in structure, have high maintenance costs, and have unsatisfactory separation effects.

[0003] In the prior art, although some patents attempt to solve the above problems, there are still some shortcomings. For example, patent number CN202210691267.4 proposes a shield slag recovery and processing device and method. Although the device can achieve the separation of slag and slag to a certain extent, it still requires manual intervention due to the lack of automatic screening and diversion mechanism, and the processing effect on large rocks is not ideal. Summary of the invention

[0004] The technical problems to be solved by the present invention are: (1) low degree of automation: relying on manual screening and cleaning, which is not only inefficient but also increases safety hazards; (2) improper handling of large rocks: large rocks can easily cause damage to equipment during transportation, and there is a lack of effective automatic diversion mechanism; (3) complex structure and difficult maintenance: existing devices often have complex structures and many parts, resulting in high maintenance costs and difficulties.

[0005] To solve the above technical problems, the technical solution provided by the present invention is: an efficient shield automatic separation device for slag and rock, comprising an original side baffle, a transverse supporting round steel, a side enlarged baffle, a retaining rubber curtain, a longitudinal screening round steel, a bottom inclined chute, and an excavation chute. A side enlarged baffle is welded on one side of the original side baffle, and a plurality of transverse supporting round steels are inserted between two opposite side enlarged baffles to achieve connection and fixation. Matching longitudinal screening round steels are arranged on the transverse supporting round steels. The two side enlarged baffles form a plate-frame structure open up and down, and a retaining rubber curtain is arranged at the side opening of the plate-frame structure. The upper part of the retaining rubber curtain is connected to the tail end of the transverse supporting round steel through a matching mounting frame; the bottom inclined chute is welded to the two upper side enlarged baffles to form a semi-open plate structure; the opening at the lower part of the original side baffle is connected with a matching excavation chute.

[0006] Furthermore, the installation steps of the efficient shield slag and rock automatic separation device include:

[0007] S1. Cut off the original tail baffle at the exit of the belt conveyor, and weld the side expansion baffle and the bottom inclined slide plate;

[0008] S2. Insert the horizontal supporting round steel into the corresponding openings of the two side expansion baffles for connection;

[0009] S3. Arrange the longitudinal screening round steels reasonably on the transverse supporting round steels according to the ground conditions, and install the retaining rubber curtain at the tail of the transverse supporting round steels.

[0010] Furthermore, during excavation, when the slag discharged by the spiral machine is transported to the high-efficiency shield slag and rock automatic separation device by the trolley belt, large pieces of rock cannot fall into the discharge chute due to the presence of longitudinal screening round steel, and can only roll along the longitudinal screening round steel to the top of the trolley behind the retaining rubber curtain. After the excavation of this ring is completed, the staff will centrally process the rocks, reducing the risk of the continuous belt being damaged by large pieces of rock during excavation. At the same time, there is no need to stop the belt conveyor for personnel to handle the belt. After the excavation is completed, the rocks can be transferred downward through the gap between the trolleys to the earth bucket for transportation.

[0011] Compared with the prior art, the advantages of the present invention are: (1) high degree of automation: through the design of longitudinal screening round steel and retaining rubber curtain, the automatic separation of slag and slag stone is realized without manual intervention; (2) the risk of equipment damage is reduced: large rocks are effectively blocked outside the excavation chute, avoiding equipment damage caused by large rocks smashing the continuous belt; (3) improving excavation efficiency: there is no need to stop the belt conveyor for manual processing, which reduces downtime and improves excavation efficiency; (4) simple structure and easy maintenance: the device of the present invention has a simple structure, few parts, low maintenance cost and easy maintenance.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0015] Embodiment 1

[0016] like Figure 1 As shown in the figure, the main components of the efficient shield slag and rock automatic separation device include:

[0017] (1) Original side baffle 1: As the basic supporting structure of the device, it is connected to the belt conveyor of the shield machine and is used to receive the slag and stone transported from the belt conveyor.

[0018] (2) Horizontal supporting round steel 2: arranged between the original side baffle 1 and the side enlarged baffle 3, used to connect and support the entire separation device.

[0019] (3) Side expansion baffle 3: connected to the original side baffle 1 through the transverse supporting round steel 2 to form an open plate-frame structure for accommodating and screening slag and rock.

[0020] (4) Earth-retaining rubber curtain 4: installed at the side opening of the side enlarged baffle 3 to block large rocks and prevent them from falling into the earth-discharging chute 7.

[0021] (5) Longitudinal screening round steel 5: It is arranged on the transverse supporting round steel 2 to form a screening grid for separating small pieces of slag and large pieces of rock.

[0022] (6) Bottom inclined chute 6: welded with the side enlarged baffle 3 to form a semi-open plate structure to guide small pieces of soil to fall into the discharge chute 7.

[0023] (7) Excavation chute 7: used to collect and transport the separated small pieces of soil, and connected to the opening at the bottom of the original side baffle 1.

[0024] In terms of connection, the original side baffle 1 and the side expansion baffle 3 are welded and connected through the transverse supporting round steel 2 to form a stable frame. The longitudinal screening round steel 5 is fixed to the transverse supporting round steel 2 by welding or snapping to form a screening grid. The retaining rubber curtain 4 is connected to the side opening of the side expansion baffle 3 through the mounting frame and can be disassembled and replaced. The bottom inclined chute 6 is connected to the side expansion baffle 3 by welding to form a semi-open plate structure. The excavation chute 7 is connected to the opening at the bottom of the original side baffle 1 by welding or bolts to ensure the smooth flow of the slag.

[0025] Embodiment 2

[0026] Based on the first embodiment, Figure 1 As shown, the main function of this device is to realize the automatic separation of slag and rock during shield construction, reduce the risk of equipment damage, improve excavation efficiency, and reduce manual intervention. Through the screening effect of the longitudinal screening round steel 5, small pieces of slag can smoothly fall into the excavation chute 7, while large pieces of rock are blocked and roll along the side expansion baffle 3 to the top of the trolley behind the retaining rubber curtain 4, realizing the automatic separation of slag and rock.

[0027] Embodiment 3

[0028] Based on the first embodiment, Figure 1As shown, the working principle of the device is as follows: during the excavation process, the slag and rock produced by the screw machine are transported to the high-efficiency shield slag and rock automatic separation device of the present invention. The slag and rock first fall on the longitudinal screening round steel 5. Due to the grid design of the screening round steel, small pieces of slag can smoothly pass through the grid and fall into the bottom discharge chute 7. Large pieces of rock are blocked by the screening round steel 5 and roll along it to the top of the trolley behind the retaining rubber curtain 4. The setting of the retaining rubber curtain 4 effectively prevents large pieces of rock from falling into the discharge chute 7, avoiding the risk of equipment damage. After the excavation is completed, the staff can centrally process these large pieces of rock, realizing the automatic separation of slag and rock.

[0029] Embodiment 4

[0030] Based on the first embodiment, Figure 1 As shown, this embodiment provides a specific implementation of an efficient shield slag and rock automatic separation device. First, the original tail end baffle at the belt conveyor exit is cut off, and then the installation is carried out according to the following steps:

[0031] S1. Install the original side baffle 1 at the outlet of the belt conveyor to ensure that it is tightly connected to the belt conveyor.

[0032] S2. Install transverse supporting round steel bars 2 on both sides of the original side baffle 1 and make them perpendicular to the original side baffle 1.

[0033] S3. Connect the side expansion baffle 3 to the original side baffle 1 through the transverse supporting round steel 2 to form an open plate-frame structure.

[0034] S4. Arrange the longitudinal screening round steels 5 rationally on the transverse supporting round steels 2 according to the stratum conditions to form a screening grid.

[0035] S5. Install retaining rubber curtains 4 at the side openings of the side enlarged baffles 3 to block large rocks.

[0036] S6. Weld the bottom inclined slide plate 6 and the side enlarged baffle plate 3 together to form a semi-open plate structure.

[0037] S7, connect the discharge chute 7 to the opening at the bottom of the original side baffle 1 to ensure that the slag can flow out smoothly.

[0038] The automatic separation device for shield slag and rock set up by the above method can effectively cope with the construction problems in shield karst development areas and other special strata. When the cutter hits the rock during excavation and large pieces of rock fall off without being squeezed and crushed by the cutter disc, it avoids the risks of large pieces of rock getting stuck at the belt conveyor outlet when being transferred to the belt conveyor by the screw conveyor and the horizontal continuous belt being damaged by large impact force.

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
