[0002] Currently, when using an earth pressure rectangular pipe jacking machine for underground construction, the slag removal process typically relies on a screw conveyor to transport the excavated soil to a dedicated slag truck. The slag truck then transports the soil to the starting pit, where a crane lifts the soil to the surface for processing. After processing, the slag truck returns to the starting pit and repositions itself at the exit of the screw conveyor to receive new soil. This cycle repeats until construction is complete.

[0003] However, since only one dump truck is deployed, excavation must stop when the dump truck is fully loaded, waiting for the muck to be processed and returned, which prolongs the standby time of the pipe jacking machine. At the same time, frequent shutdowns increase the risk of the pipe jacking machine's cutterhead getting stuck and the formation collapsing in complex strata, resulting in low excavation efficiency and poor construction continuity. In summary, the existing mud discharge system of the earth pressure rectangular pipe jacking machine has the technical defects of long equipment downtime, low excavation efficiency, and poor construction continuity.

[0030] like Figures 1 to 6 As shown, the embodiment of the present invention provides a continuous slag discharge system for a soil pressure rectangular pipe jacking machine, comprising: a slag discharge channel 1; a slag bucket 4 for loading slag, the slag bucket 4 having a full slag state and an empty slag state; a slag receiving position 501 located below the slag discharge channel 1; a slag transport position 502 located behind the slag receiving position 501; a slag receiving device 2 located below the slag outlet of the slag discharge channel 1, the slag receiving device 2 being used to be at the slag receiving position 501, receiving the slag output from the slag discharge channel 1 through the slag bucket 4 in the empty slag state, and the slag receiving device 2 is also used to move to the slag transport position 502 to load the slag bucket 4 in the empty slag state and return to the slag receiving position 50 1; a slag conveying device 3 located behind the slag receiving device 2, the slag conveying device 3 is used to transport the slag bucket 4 in a full slag state to the starting well, and transport the slag bucket 4 in an empty slag state back to the slag transport position 502; a slag bucket moving mechanism 6 provided on the slag receiving device 2 and the slag conveying device 3, the slag bucket moving mechanism 6 is used to move the slag bucket 4 in a full slag state on the slag receiving device 2 to the slag conveying device 3; a slag bucket lifting mechanism 7 provided on the pipe segment lifting lug 8 of the pipe jacking machine, the slag bucket lifting mechanism 7 is used to lift the slag bucket 4 in an empty slag state on the slag conveying device 3 and lower it to the slag receiving device 2.

In summary, traditional methods of handling slag often require frequent downtime to wait for slag removal. The continuous slag discharge system, by continuously discharging slag, reduces manual intervention in the slag handling process and can continuously process slag without stopping pipe jacking. This shortens the construction cycle and reduces operating costs, thereby improving excavation efficiency and the equipment's construction continuity. Compared with the existing technology, the technical solution involved in this utility model can reduce equipment downtime, improve excavation efficiency, and improve the equipment's construction continuity.

[0032] Specifically, in the embodiment of the present utility model, the bucket 4 includes: a bucket box body 14; a bucket ring structure 13 arranged on both sides of the bucket box body 14 for connecting to the bucket moving mechanism 6; and a bucket lifting ring structure 12 arranged on the top of the bucket box body 14 for connecting to the bucket lifting mechanism 7.

[0033] The bucket housing 14 is used to hold excavated soil. The bucket buckle structure 13 cooperates with the bucket moving mechanism 6 to stabilize the bucket 4, preventing it from shaking or shifting during transportation, thereby preventing soil spillage or falling off. The bucket lifting ring structure 12 connects to the bucket lifting mechanism 7, facilitating the lifting and lowering of the bucket 4, thereby enabling rapid transfer of the bucket 4 between different transport vehicles. The coordination of the structure on the bucket 4 and the various mechanisms of the slag discharge system reduces manual intervention in the soil handling process, improves the degree of automation, and thus enhances the efficiency and safety of soil transportation, thereby improving the continuity of pipe jacking machine construction.

[0034] Specifically, in the embodiment of the utility model, the residue bucket hoisting mechanism 7 comprises: a crane arranged on the pipe section 15 of the pipe jacking machine;A crane control system arranged on the crane for controlling the crane;A crane driving system arranged on the crane for driving the crane to move;A hook cable structure arranged on the crane for connecting the residue bucket lifting ring structure 12.

[0035] Wherein, through the crane control system to control the crane, can ensure that the residue bucket 4 remains stable during lifting and placing, reduce the risk of residue soil falling;The crane driving system provides power support for the crane, reduces the need for manual intervention, improves the degree of automation of the system;The hook cable structure and the residue bucket lifting ring structure 12 closely cooperate to ensure the positioning accuracy of the residue bucket 4 during lifting and placing. The efficient operation of the residue bucket hoisting mechanism 7 optimizes the residue soil management process, reduces the equipment downtime, and improves the tunneling efficiency.

[0036] Specifically, in the embodiment of the utility model, the residue soil receiving device 2 and the residue soil conveying device 3 comprise: a transport vehicle base 10;The axle is arranged on the transport vehicle base 10;The wheels 9 are arranged on the axle;The transport vehicle driving system is arranged on the transport vehicle base 10, and the driving shaft is connected with the axle;The weight detection system is arranged on the transport vehicle base 10.

[0037] Wherein, each residue soil transport vehicle has a transport vehicle base 10 as the main frame, and the four corners of the transport base 10 are provided with wheels 9, so that the residue soil transport vehicle moves along the predetermined track. The front axle or the rear axle is connected with the driving shaft of the transport vehicle driving system, and the transport vehicle driving system provides power, so that the residue soil transport vehicle can move autonomously, and the four-wheel structure helps to keep the stability of the vehicle. Through the optimized wheel layout and driving system, the residue soil transport vehicle can move smoothly inside the pipe jacking machine, and the residue soil transfer speed is accelerated.

[0038] Specifically, in the embodiment of the utility model, the weight detection system comprises: a weight sensor;The vehicle controller is connected with the weight sensor for controlling the movement of the residue soil receiving device 2 and the residue soil conveying device 3.

[0039] When the weight of the slag bucket 4 reaches a preset value, the weight sensor transmits the weight information to the control system and the vehicle controller. The vehicle controller moves the transport vehicle to a preset position, and the control system activates the slag bucket moving mechanism 6 and the slag bucket lifting mechanism 7 to lift the empty slag bucket 4 on the slag conveying device 3 to a preset height and move the full slag bucket 4 from the slag receiving device 2 to the slag conveying device 3. When the full slag bucket 4 begins processing, the weight detection system detects the weight change of the slag bucket 4, and the control system activates the slag bucket lifting mechanism 7 to lower the empty slag bucket to the slag receiving device 2 to prepare to receive new slag. The weight detection system enables the continuous slag discharge system to achieve more precise control and higher efficiency during operation. It not only improves the accuracy and timeliness of the slag bucket 4 switching and prevents overload, but also reduces manual intervention, improves the safety and reliability of the operation, and ensures the continuity and efficiency of the entire slag discharge process.

[0040] Specifically, in an embodiment of the present utility model, it also includes: a transport vehicle positioning system for positioning the slag receiving device 2 and the slag conveying device 3, the transport vehicle positioning system including: a transport vehicle positioning part arranged at the bottom of the slag receiving device 2 and the slag conveying device 3; a ground positioning hole arranged at a preset position on the ground; a positioning sensor arranged on the transport vehicle positioning part and the ground positioning hole, the positioning sensor being used to detect the position status of the transport vehicle; an electronic signal lock arranged between the transport vehicle positioning part and the ground positioning hole; a central controller for coordinating and controlling the slag discharge system, the central controller being used to receive signals from the positioning sensor and the weight sensor, and send instructions to the vehicle controller and the electronic signal lock.

[0041] Among them, the transport vehicle positioning system achieves precise positioning through the transport vehicle positioning part and the ground positioning holes at preset positions on the ground. The positioning sensor detects the position status of the transport vehicle in real time and transmits the information to the central controller. The central controller receives signals from the positioning sensor and weight sensor, analyzes the data, and sends instructions to the vehicle controller and the electronic signal lock. When the transport vehicle reaches the preset position, the electronic signal lock locks the transport vehicle to ensure its precise position during the slag receiving and transportation process. The transport vehicle positioning system not only improves the positioning accuracy of the slag receiving device 2 and the slag conveying device 3, reduces position deviation, but also ensures the continuity and efficiency of the entire slag discharge process, thereby improving the slag discharge efficiency and reliability of the slag discharge system.

[0042] Specifically, in the embodiment of the present utility model, the hopper moving mechanism 6 is specifically a belt conveyor device or a winch device.

[0043] More specifically, in an embodiment of the present invention, the belt transport device includes: a support frame; a pulley provided on the support frame; a belt installed on the pulley; a tensioning device provided at one end of the belt; a belt drive system that drives the pulley to rotate; and a roller for supporting the belt.

[0044] Specifically, in an embodiment of the present utility model, the winch device includes: a winch base arranged on the base 10 of the slag transport vehicle; a rotating drum structure arranged on the winch base; a steel strand installed on the rotating drum structure; a winch drive system arranged on the winch base; the winch drive system drives the rotating drum structure to rotate, and the rotation of the rotating drum structure drives the steel strand to be retracted and extended, and the retraction and extension of the steel strand drives the slag bucket 4 to move.

[0045] The belt conveyor utilizes a high-strength belt and multiple sets of rollers to ensure smooth and stable movement of the bucket. The pulleys at each end of the belt are driven by a belt drive system, with a tensioning device maintaining belt tension to reduce slippage and slack. The winch system, comprised of a winch base and a rotating drum structure mounted on the transport vehicle's chassis, smoothly moves the bucket from the soil receiving device to the soil conveying device by stretching and retracting the steel strands. The winch drive system drives the rotating drum, ensuring rapid and precise transfer of the bucket. The bucket moving mechanism 6 effectively improves bucket movement efficiency, reduces manual intervention, and ensures the continuity and efficiency of the slag discharge system.

[0046] Among them, the bucket moving mechanism 6 can smoothly move the bucket 4 from one transport vehicle to another by stretching and recovering the steel strand, ensuring the rapid transfer of the bucket 4; by quickly moving the bucket 4, the slag processing and excavation operations are carried out simultaneously, so that the slag processing does not need to interrupt the excavation work of the pipe jacking machine, thereby reducing the downtime of the equipment and improving the excavation efficiency.

[0047] Specifically, in an embodiment of the present utility model, it also includes: a guide device arranged on the transport vehicle base 10 and in the same straight line with the center of the winch base, the guide device includes: a guide rail; side baffles arranged on both sides of the guide rail, the side baffles are used to prevent the slag bucket 4 from deviating or falling during movement.

[0048] The guide rails ensure the bucket 4 moves smoothly along the predetermined path, while the side guards provide lateral restraint, preventing the bucket from lateral deviation or falling during movement, thereby improving the bucket's movement accuracy and safety. The guide device not only enhances the stability and reliability of the slag discharge system, but also ensures the continuity and efficiency of the bucket during lifting and transportation.

[0049] In addition, an embodiment of the present invention also provides a pipe jacking machine system, including the continuous slag discharge system for the earth pressure rectangular pipe jacking machine as described above, which also has the above-mentioned technical effects.

[0050] More specifically, in the embodiment of the present invention, the slag discharge channel 1 is specifically a screw conveyor.

[0051] To elaborate more specifically, the slag removal method currently used by earth pressure rectangular pipe jacking machines typically involves using a screw conveyor to transport the slag into a dump truck, which then transports it to the starting shaft. The truck then lifts the slag to the ground for processing. Once the processing is complete, the dump truck is hoisted back into the starting shaft and runs to the screw conveyor outlet to receive the slag, completing the slag processing cycle. Since existing pipe jacking machines are typically equipped with only one dump truck, when the dump truck is fully loaded, the machine must stop excavating and wait for the dump truck to transport the slag to the ground for processing. Only after the slag is processed and the dump truck returns to the screw conveyor outlet can the machine continue excavating. As the jacking distance increases, the round-trip time of the dump truck also increases, resulting in a longer standby time for the pipe jacking machine, which in turn affects the construction progress. Furthermore, in complex strata, long periods of downtime during pipe jacking increase the risk of the cutterhead getting stuck, ground collapse, or ground uplift, thereby affecting construction quality and safety.

[0052] The technical solution provided by this utility model adopts a continuous slag discharge system to ensure the continuous jacking of the pipe jacking machine. When the slag truck is fully loaded, the system can quickly switch the slag bucket, thereby minimizing downtime, effectively solving the above-mentioned problem and ensuring the continuity and construction efficiency of the pipe jacking machine during the jacking process.

[0053] Specifically, in order to achieve continuous slag discharge, the utility model adopts two sets of dump trucks arranged in front and behind: during jacking, the front slag receiving device receives the slag, and the rear slag conveying device is ready to replace the slag receiving device to complete the transportation; when the slag receiving device is fully loaded, the slag bucket lifting mechanism is used to lift the slag bucket in the empty slag state, and the slag bucket in the full slag state is moved to the slag conveying device through the rear slag bucket moving mechanism; then, the slag conveying device transports the slag bucket in the full slag state to the starting well for processing the slag; at the same time, the slag receiving device is moved to the original position of the slag conveying device, and the slag bucket in the empty slag state is placed on the slag receiving device; then, the slag receiving device returns to receive the slag, and the slag conveying device returns to the rear of the slag receiving device to prepare after processing the slag, and this cycle is repeated, thereby realizing continuous slag reception and delivery, reducing downtime, and improving construction efficiency.

[0054] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
