Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, and particularly relates to a mud-water circulation pipe jacking machine. Background Technique

[0002] Pipe jacking machines are commonly used in underground tunneling operations in municipal engineering. The mud-water circulation pipe jacking machine is a commonly used pipe jacking machine. The mud-water circulation pipe jacking machine injects mud-water into the cutter head through a slurry inlet pipe, and the mud-water discharges the excavated muck underground through a slurry outlet pipe, so as to achieve continuous muck discharge and tunneling.

[0003] The applicant found through retrieval that the Chinese patent discloses a "mud-water circulation pipe jacking machine", and its publication (announcement) number is "CN220869405U". This patent mainly includes a cutter head, a pipe jacking machine body and a slag filtering device. The cutter head is used for cutting rock and soil. The cutter head is arranged at the end of the pipe jacking machine body. The pipe jacking machine body is used to drive the cutter head forward. The slag filtering device is arranged on the slurry outlet pipe of the pipe jacking machine body. The slag filtering device can block the muck from passing through the slurry outlet pipe. When the pipe jacking machine excavates stones and causes the tunneling speed to decrease, the slag filtering device can block the excavated muck from passing through the slurry outlet pipe, while the pressurized mud-water can pass through normally, and the muck will not be taken away by the pressurized mud-water through the slurry outlet pipe, so as to accumulate between the cutter head and the face, prevent the rock and soil of the face from being hollowed out, effectively avoid the subsidence or collapse of the upper stratum, and improve the construction safety.

[0004] When breaking larger rock and soil and stones, it is difficult to be smoothly processed by the pipe jacking machine, resulting in the drill bit needing to spend more time and energy to repeatedly break during the rock breaking process, so that the overall rock breaking speed drops significantly. When cutting larger rock and soil and stones, the impact force and friction force borne by the drill bit are greater, which easily causes the drill bit to wear, crack, and even deform or be damaged. Moreover, the cut fragments are easy to accumulate around the pipe jacking machine, resulting in blockage when the pipe jacking machine advances forward. Construction workers need to frequently stop the machine for cleaning or treatment, which not only interrupts the continuity of construction, but also increases the additional downtime for treatment, seriously affecting the construction progress. Therefore, the fragments cannot be recycled, and the concept of green construction cannot be met. For this reason, we propose a mud-water circulation pipe jacking machine.

[0009] As a further solution of the present utility model: A slurry outlet pipe is connected below the pipe jacking machine body, and a slag filter screen is assembled above the slurry outlet pipe.

[0010] As a further solution of the present utility model: A second motor is arranged on the inner wall of the second connection seat, a pulley is connected to the driving end of the second motor, two groups of pulleys are provided, a belt is sleeved outside the two groups of pulleys, a stirring shaft is arranged on one side of the belt, crushing knives are assembled on both sides of the stirring shaft, two groups of the crushing knives and the stirring shaft are provided, and the two groups of crushing knives are arranged in a staggered structure.

[0011] Adopting the above technical solutions, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Through the setting of the cutting component in the present utility model, due to the rotation of the cutter head, the drill bit rotates synchronously. During the strong rotation of the drill bit, the external spiral blades rotate at high speed together with the drill bit, generating a rotational impact force to initially break the rock and soil and stones. Moreover, through continuous agitation, the rock and soil and stones rub and collide with each other, further strengthening the crushing effect and prompting them to disintegrate into smaller fragments. At the same time, the cutters surrounding the drill bit cut into the rock and soil as the drill bit advances deeper into the rock and soil, thereby finely cutting the larger-volume rock and soil and stones into smaller fragments;

[0013] 2. Through the setting of the buffer column and the spring in the present utility model, when the drill bit encounters a large resistance or impact force during the cutting process, the buffer column can buffer and absorb part of the impact force through its own deformation ability. And when the buffer column is subjected to the impact force, the disc spring inside it is compressed, converting the impact energy into the elastic potential energy of the spring, and then releasing the energy at an appropriate time, playing a dual role of buffering and shock absorption, and further improving the impact resistance of the cutting component;

[0014] 3. Through the setting of the slag suction component in the present utility model, the slag suction head sucks the crushed soil and fragments under the action of negative pressure. And during the suction process of the slag suction head, larger stones or sundries are intercepted by the grille. The soil and fragments enter the slag suction head through the grille and enter the slag suction pipe through the branch pipe, and thus enter the main body of the pipe jacking machine through the slag inlet. Therefore, not only the collection of the soil is realized, but also the accumulation of the soil is prevented from causing the main body of the pipe jacking machine to be unable to advance forward;

[0015] 4. Through the stirring shaft and the crushing knife in the present utility model, the soil and fragments entering the main body of the pipe jacking machine are crushed, so that the crushed soil and fragments can be reused, reducing resource waste.

[0016] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, they will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

Specific embodiments

[0024] The following further describes the specific embodiments of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present utility model, but does not constitute a limitation to the present utility model.

[0025] In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to the attached Figure 1 - attached Figure 6 , a mud circulation pipe jacking machine of the present utility model includes the main body 1 of the pipe jacking machine. For example, Figure 2 , Figure 5 , Figure 6As shown in the figure, a slag suction assembly 202 is assembled at the front end of the pipe jacking machine body 1 and is connected to the first connecting seat 2. A second connecting seat 3 is assembled at the rear end of the pipe jacking machine body 1, and a cutting assembly 201 is assembled at the front end of the second connecting seat 3. The cutting assembly 201 includes a first motor 2010, a rotating shaft 2011, a cutter head 2012, a base 2013, a buffer column 2014, a disc spring 2015, a drill bit 2016, a spiral blade 2017, and a cutting tool 2018. The first motor 2010 is located in the middle of the inner wall of the first connecting seat 2. The rotating shaft 2011 is connected to the driving end of the first motor 2010. The base 2013 is arranged on the inner wall of the cutter head 2012. The disc spring 2015 is arranged on the inner wall of the buffer column 2014. The spiral blade 2017 is sleeved on the outer wall of the drill bit 2016. The cutting tool 2018 surrounds the drill bit 2016. A plurality of cutting tools 2018 and drill bits 2016 are provided. By driving the rotating shaft 2011 to rotate by the first motor 2010, since the rotation of the rotating shaft 2011 drives the cutter head 2012 to rotate, at this time, the drill bit 2016 is driven by the rotation of the cutter head 2012 and drills into the interior of the rock and soil, breaking the rock and soil into small pieces. And during the strong rotation of the drill bit 2016, the external spiral blade 2017 rotates at a high speed together with the drill bit 2016, and the generated rotational impact force performs primary crushing on the rock and soil and stones. Moreover, through continuous agitation, the rock and soil and stones rub and collide with each other, further strengthening the crushing effect and prompting them to disintegrate into smaller fragments. Since the drill bit 2016 continuously advances deep into the rock and soil, the cutting tools 2018 surrounding the drill bit 2016 cut into the rock and soil as the drill bit 2016 advances deep into the rock and soil, thereby finely cutting the rock and soil and stones with a larger volume into smaller fragments. And when the drill bit 2016 encounters a large resistance or impact force during the cutting process, since the buffer column 2014 can be made of rubber material, the buffer column 2014 can buffer and absorb a part of the impact force through its own deformation ability. And when the buffer column 2014 is subjected to the impact force, the disc spring 2015 inside it is compressed, converting the impact energy into the elastic potential energy of the spring, and then releasing the energy at an appropriate time, playing a dual role of buffering and shock absorption, and further improving the impact resistance of the cutting assembly 201.

[0027] Embodiment 1. The slag suction assembly 202 includes a vacuum pump 2021, a connecting pipe 2022, a slag suction pipeline 2023, a branch pipe 2024, a slag suction head 2025, a grille 2026, and a slag inlet 2027. The vacuum pump 2021 is located on both sides of the inner wall of the second connecting seat 3. The vacuum pump 2021 is connected to the slag suction pipeline 2023 through the lower connecting pipe 2022. A separator net is provided at the connection between the connecting pipe 2022 and the slag suction pipeline 2023. There are two sets of the connecting pipe 2022, the slag suction pipeline 2023, and the vacuum pump 2021. The branch pipe 2024 communicates with the slag suction head 2025 through the penetration of the cutter head 2012. The slag suction head 2025 is arranged on the inner wall of the cutter head 2012. A grille 2026 is assembled on the inner wall of the slag suction head 2025. There are eight sets of the slag suction head 2025 and the branch pipe 2024. The eight sets of branch pipes 2024 are connected to the slag suction pipeline 2023, and each of the two slag suction pipelines 2023 is connected to four branch pipes 2024. The slag inlet 2027 is located at the connection between the slag suction pipeline 2023 and the pipe jacking machine body 1;

[0028] Specifically, the vacuum pump 2021 generates a strong negative pressure. This negative pressure force is quickly conducted to the slag suction pipeline 2023 through the connecting pipe 2022. Subsequently, the branch pipe 2024 further distributes the negative pressure to each slag suction head 2025. At this time, the soil and debris in the cutting area of the cutter head 2012 converge towards the slag suction head 2025 under the attraction of the negative pressure. The grille 2026 inside the slag suction head 2025 intercepts larger-sized debris and sundries, ensuring that only the fine soil and debris that meet the requirements can pass through, effectively avoiding the potential risk of subsequent pipeline blockage. The soil and debris screened by the grille 2026 flow into the slag suction pipeline 2023 along the branch pipe 2024 in an orderly manner. At this time, the separator net provided between the slag suction pipeline 2023 and the connecting pipe 2022 prevents the soil and debris from entering the vacuum pump 2021. Therefore, the soil and debris enter the pipe jacking machine body 1 through the slag inlet 2027.

[0029] Embodiment 2. A slurry discharge pipe 5 is connected below the pipe jacking machine body 1, and a filter residue sieve 501 is assembled above the slurry discharge pipe 5;

[0030] Specifically, when discharging the slurry liquid from the pipe jacking machine body 1, the slurry liquid is discharged through the slurry discharge pipe 5. When the slurry liquid contacts the filter residue sieve 501, the slurry is filtered by the filter residue sieve 501 to block larger particle impurities, making the discharged slurry purer. The intercepted particle impurities are temporarily retained in the pipe jacking machine body 1, and the residual particle impurities are crushed twice to make them gradually finer until they can be discharged through the filter residue sieve 501, effectively avoiding large particle impurities from entering the slurry discharge pipe 5 and causing pipeline blockage, ensuring the smoothness of the slurry discharge pipe 5, and improving the effect of soil and debris treatment.

[0031] Embodiment 3: A second motor 6 is provided on the inner wall of the second connecting seat 3, and a sleeve wheel is connected to the driving end of the second motor 6. Two sets of sleeve wheels are provided, and belts 7 are provided on the outside of the two sets of sleeve wheels. A stirring shaft 8 is provided on one side of the belt 7, and crushing knives 9 are installed on both sides of the stirring shaft 8. Two sets of crushing knives 9 and stirring shaft 8 are provided, and the two sets of crushing knives 9 are staggered structures;

[0032] Specifically, the drive of the second motor 6 causes the belt 7 to rotate outside the sleeve wheel. The rotation of the belt 7 drives the two sets of stirring shafts 8 and the crushing knife 9 to rotate. During the rotation, the crushing knife 9 crushes the slag and fragments entering the pipe jacking machine body 1. The two sets of crushing knives 9 form a staggered structure, so that when driven by the stirring shaft 8, the crushing knife 9 can cut and crush the slag and fragments from different angles and positions when rotating, thereby expanding the coverage of a single crushing and improving the crushing efficiency. Therefore, the crushing knife 9 can effectively crush larger slag blocks, stones, etc. into smaller particles, thereby realizing the utilization of slag blocks and stones.

[0033] Working principle:

[0034] First, muddy water enters the pipe jacking machine body 1 through the slurry inlet pipe 4, and the first motor 2010 drives the rotating shaft 2011 to rotate the cutter head 2012, so that the drill bit 2016 breaks the rock and stone, and the spiral blades 2017 outside the drill bit 2016 stir, so that the rock and stone can be broken into smaller pieces. As the drill bit 2016 continues to go deeper, the cutter 2018 finely cuts the larger volume of rock and stone into smaller pieces.

[0035] When the rock and stone are crushed, the negative pressure generated by the vacuum pump 2021 causes the slag and debris to enter the slag suction head 2025, and the larger debris and sundries are intercepted by the grille 2026. Therefore, the entered slag and debris enter the slag suction pipe 2023 through the branch pipe 2024. At this time, the partition net provided at the connection between the connecting pipe 2022 and the slag suction pipe 2023 prevents the slag and debris from entering the vacuum pump 2021, and enters the pipe jacking machine body 1 through the slag inlet 2027.

[0036] Subsequently, the second motor 6 drives the belt 7 to rotate outside the sleeve, and drives the stirring shaft 8 and the crushing knife 9 to crush the incoming slag and debris into smaller particles, which are then discharged through the slurry outlet pipe 5. At this point, the entire work process ends.

[0037] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0039] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings, but the present utility model is not limited to the described embodiments.

[0040] For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present utility model.
