Description

TECHNICAL FIELD

[0001] The utility model relates to civil engineering device, concretely point to a kind of high-efficiency shield slag soil slag stone automatic separation device. BACKGROUND

[0002] In the process of shield construction, the effective separation of slag soil and slag stone is an important link to ensure the efficiency of tunneling and construction safety. Traditional shield slag soil treatment system mostly relies on simple belt conveyor transportation and subsequent manual screening. This method has many drawbacks. First, manual screening is not only inefficient, but also has a poor working environment, which poses a serious threat to the health of workers. Second, large rocks can easily damage equipment during belt conveyor transportation, leading to frequent downtime for maintenance and increasing construction costs. In addition, although some existing shield slag soil treatment devices attempt to achieve automated separation, they often have complex structures, high maintenance costs, and unsatisfactory separation results.

[0003] In the prior art, although some patents attempt to solve the above problems, there are still deficiencies. For example, patent number CN202210691267.4 proposes a shield slag soil recycling and processing device and method. Although this device can achieve the separation of slag soil and slag stone to some extent, it still requires manual intervention due to the lack of automatic screening and diversion mechanisms, and the treatment effect for large rocks is not ideal. SUMMARY

[0004] The technical problems to be solved by the utility model are: (1) low degree of automation: relying on manual screening and cleaning, which not only reduces efficiency but also increases safety hazards; (2) improper handling of large rocks: large rocks can easily damage 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 numerous components, resulting in high maintenance costs and difficulty in maintenance.

[0005] To solve the above technical problems, the technical solution provided by the utility model is: a high-efficiency shield slag soil slag stone automatic separation device, comprising a primary side baffle, a horizontal support round steel, a side expansion baffle, a soil-blocking rubber curtain, a longitudinal screening round steel, a bottom inclined chute, and a soil outlet chute. The side expansion baffle is welded to one side of the primary side baffle. Multiple horizontal support round steels are arranged between the two opposite side expansion baffles to achieve connection and fixation. The horizontal support round steel is provided with a matching longitudinal screening round steel. The two side expansion baffles form an open-top plate frame structure. The soil-blocking rubber curtain is arranged at the side opening of the plate frame structure. The upper part of the soil-blocking rubber curtain is connected to the tail end of the horizontal support round steel through a matching mounting bracket. The bottom inclined chute and the two side expansion baffles above form a semi-open plate body structure. The opening at the lower part of the primary side baffle is connected to a matching soil outlet chute.

[0006] Further, the installation steps of the high-efficiency automatic shield muck and muckstone separating device include:

[0007] S1, cut off the original tail end baffle at the belt conveyor earth outlet, weld the side edge expanded baffle and the bottom inclined chute;

[0008] S2, pass the transverse support round steel into the corresponding openings between the two side edge expanded baffles;

[0009] S3, reasonably arrange the longitudinal screening round steel on the transverse support round steel according to the stratum condition, and install the soil blocking rubber fabric at the tail of the transverse support round steel.

[0010] Further, when tunneling, the muck discharged by the screw machine is transported to the high-efficiency automatic shield muck and muckstone separating device by the trolley belt, because there is the longitudinal screening round steel, the large rocks cannot fall into the earth outlet chute, but can only roll along the longitudinal screening round steel to the top of the trolley behind the soil blocking rubber fabric, and the rocks are concentrated and processed by the staff after the ring tunneling is completed, which reduces the risk of continuous belt being damaged by large rocks in the tunneling process, and personnel do not need to stop the belt machine to process on the belt, and after the tunneling is completed, the rocks can be transported downward to the hopper through the gap between the trolleys for transportation.

[0011] Compared with the prior art, the advantages of the utility model lie in that: (1) high degree of automation: through the design of the longitudinal screening round steel and the soil blocking rubber fabric, the automatic separation of muck and muckstone is realized without manual intervention; (2) reduce the risk of equipment damage: the large rocks are effectively blocked outside the earth outlet chute, avoiding the damage of the equipment caused by the large rocks hitting the continuous belt; (3) improve the tunneling efficiency: without stopping the belt machine for manual processing, the downtime is reduced, and the tunneling efficiency is improved; (4) simple structure and convenient maintenance: the device structure of the utility model is simple, the parts are few, the maintenance cost is low, and the maintenance is convenient.

[0014] The utility model will be further described in detail in combination with the drawings.

[0015] Example 1

[0016] As shown in the figure, the main parts of the high-efficiency automatic shield muck and muckstone separating device include: Figure 1 ​

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

[0018] (2) Lateral support round steel 2: It is set between the original side baffle 1 and the side enlarged baffle 3 to connect and support the entire separation device.

[0019] (3) Side enlarged baffle 3: It is connected to the original side baffle 1 by the transverse support round steel 2 to form an open plate frame structure for accommodating and screening slag and slag.

[0020] (4) 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 chute 7.

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

[0022] (6) Bottom inclined slide 6: Welded to the side enlarged baffle 3 to form a semi-open plate structure, guiding small pieces of slag to fall into the chute 7 at the soil outlet.

[0023] (7) Exit chute 7: Used to collect and transport small pieces of slag after separation, 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 enlarged baffle 3 are welded together by transverse support round steel 2 to form a stable frame. The longitudinal screening round steel 5 is fixed to the transverse support round steel 2 by welding or snap-fit ​​to form a screening grid. The retaining rubber curtain 4 is connected to the side opening of the side enlarged baffle 3 by a mounting bracket and can be disassembled and replaced. The bottom inclined chute 6 is connected to the side enlarged baffle 3 by welding to form a semi-open plate structure. The discharge chute 7 is connected to the lower opening of the original side baffle 1 by welding or bolts to ensure smooth discharge of the excavated soil.

[0025] Example 2

[0026] Based on Example 1, such as Figure 1 As shown, the main function of this device is to automate the separation of excavated soil and slag during shield tunneling, reduce the risk of equipment damage, improve tunneling efficiency, and reduce manual intervention. Through the screening action of the longitudinal screening round steel 5, small pieces of excavated soil can fall smoothly into the discharge 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, thus realizing the automatic separation of excavated soil and slag.

[0027] Example 3

[0028] Based on the embodiment one, as shown in Figure 1 The working principle of the device is as follows: during the tunneling process, the spoil and rock debris discharged by the screw machine are conveyed to the high-efficiency shield spoil and rock debris automatic separation device. The spoil and rock debris first fall on the longitudinal screening round steel 5. Since the screening round steel is designed with a grid, small pieces of spoil can pass through the grid and fall into the bottom of the earth outlet chute 7. Large rocks are blocked by the screening round steel 5 and roll along the top of the car behind the soil-blocking rubber curtain 4. The setting of the soil-blocking rubber curtain 4 effectively prevents large rocks from falling into the earth outlet chute 7, avoiding the risk of equipment damage. After the tunneling is completed, the workers can concentrate on processing these large rocks, realizing the automatic separation of spoil and rock debris.

[0029] Embodiment four

[0030] Based on the embodiment one, as shown in Figure 1 The embodiment provides a specific implementation of a high-efficiency shield spoil and rock debris automatic separation device. First, the original tail end baffle at the earth outlet of the belt conveyor is cut off, and then installed 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 with the belt conveyor.

[0032] S2, install a horizontal support round steel 2 on both sides of the original side baffle 1, and make it perpendicular to the original side baffle 1.

[0033] S3, connect the side expansion baffle 3 with the original side baffle 1 through the horizontal support round steel 2 to form an open plate frame structure.

[0034] S4, arrange the longitudinal screening round steel 5 on the horizontal support round steel 2 according to the stratum conditions to form a screening grid.

[0035] S5, install the soil-blocking rubber curtain 4 at the side opening of the side expansion baffle 3 to block large rocks.

[0036] S6, weld the bottom inclined chute 6 with the side expansion baffle 3 to form a semi-open plate structure.

[0037] S7, connect the earth outlet chute 7 with the opening at the lower part of the original side baffle 1 to ensure that the spoil flows out smoothly.

[0038] The shield spoil and rock debris automatic separation device set by the above method can effectively deal with the construction problems in shield karst development areas and other special strata. In the case of large rocks falling without being crushed by the cutter head during the tunneling process, the device can avoid the risk of large rocks being stuck in the earth outlet of the belt conveyor, and the damage of the horizontal continuous belt caused by large impact force.

[0039] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and the skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed.
