Description

Technical Field

[0001] The present invention relates to the field of shaft boring machines, and in particular to a main compartment for a shaft boring machine and the shaft boring machine. Background Art

[0002] During operation, the main chamber of a shaft boring machine is completely immersed in muddy water. A slewing bearing drives the actuator at the bottom of the main chamber to rotate back and forth to perform excavation. Existing shaft boring machines, due to the different connection points for pipes and lines such as hydraulic lines, cables, hydraulic lines, and grease lines, and the fact that the middle section is suspended in the air except for the two end connection points, cause the pipes and lines to sway and become entangled as the slewing bearing rotates, making management and maintenance difficult. Therefore, designing a main chamber and shaft boring machine for a shaft boring machine that facilitates the management and maintenance of internal pipes and lines is a challenge facing those skilled in the art. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing main compartment of a shaft boring machine and the chaotic distribution of pipes and wires inside the shaft boring machine, the present application provides a main compartment for a shaft boring machine and a shaft boring machine to solve the problems existing in the prior art.

[0004] The technical solutions provided in this application are as follows:

[0005] The present application provides a main compartment for a shaft boring machine, characterized in that it includes: a main compartment frame; a slewing mechanism connected to the main compartment frame via a slewing bearing, the slewing mechanism including a slewing center mechanism, a slewing flange connected to the slewing center mechanism, and a power ring device connecting the slewing flange and the slewing bearing; a drag chain device, one end of the drag chain device is connected to the slewing center mechanism and the other end is connected to the main compartment frame, and the tubes and / or wires in the drag chain device are arranged inside the slewing center mechanism; a sealing device connected to the main compartment frame and the slewing bearing, the sealing device including a plurality of sealing structures arranged in sequence from the main compartment frame to the slewing bearing. When the slewing bearing rotates, the fixed ring is connected to the main compartment frame and remains stationary, and the rotating ring transmits power to the power ring device through the power ring device, the power ring device is connected to the slewing flange, and the slewing flange drives the slewing center mechanism to rotate. Water pressure pipes, cables, hydraulic pipes, grease pipes, and other pipes and / or wires are arranged in the drag chain device and pass through the interior of the slewing center mechanism to reach the actuator at the bottom of the main warehouse. When the slewing center mechanism rotates, the end of the drag chain device connected to the slewing center mechanism rotates accordingly, and the end of the drag chain device connected to the main frame of the main warehouse is fixed. The horizontal pipes and / or wires are centrally managed by the drag chain device, and the vertical pipes and / or wires are centrally managed by the slewing center mechanism. This structure facilitates the centralized management of pipes and / or wires and is compact. When the pipes and / or wires need to be repaired or replaced, it is more convenient to operate and can improve work efficiency. The sealing device achieves the sealing effect through an end face seal, a radial outer seal, and a lip seal. At the same time, it can withstand a certain pressure in conjunction with the use of grease, ensuring sealing performance and improving the management efficiency of pipes and / or wires without affecting the rotational motion.

[0006] Furthermore, the present application provides a preferred solution, further comprising: a drag chain guide mechanism, the drag chain guide mechanism being disposed openly around the rotation center mechanism; the drag chain guide mechanism comprising a guide plate and a bracket, the bracket being connected to the main compartment frame. The guide plate of the drag chain guide mechanism is a component having an arc-shaped cross-section, which is used to guide the drag chain device around the rotation center mechanism and rotate with it, limiting the movement area of ​​the drag chain device during rotation, preventing it from moving outside the area planned by the drag chain guide mechanism to avoid affecting the operation of other structures. The drag chain guide mechanism serves as a guide and avoidance mechanism.

[0007] Furthermore, the present application provides a preferred embodiment in which the slewing center mechanism includes a first chamber and a second chamber, the second chamber being within the first chamber. The pipes and / or wires in the drag chain device are arranged inside the first chamber and outside the second chamber. The cables, hydraulic lines, grease lines, hydraulic lines, and other pipes and / or wires for the actuator at the bottom of the main compartment are inserted through the first chamber of the slewing center mechanism at one end and secured by the drag chain device, with the other end secured to the actuator. Without passing through the first chamber, the pipes and / or wires would be threaded directly through the slewing flange, leaving them hanging in the middle, resulting in a messy and difficult management. The second chamber is exposed to muddy water. Mud in the well is pumped into the second chamber by the actuator and discharged through the first chamber. Hydraulic pipes, mud pipes, cables, grease lines, hydraulic lines, and other pipes and / or wires can be centrally connected from the first chamber to the actuator. The second chamber serves as a mud channel for the actuator's pump to pump mud and discharge it to the surface.

[0008] Furthermore, the present application provides a preferred solution, further comprising a motor connected to the slewing bearing and a reducer connected to the slewing bearing. The motor provides power to rotate the slewing bearing, thereby driving the corresponding power ring device, the slewing flange connected to the power ring device, and the slewing center mechanism connected to the slewing flange to rotate; when the slewing center mechanism is about to rotate to a preset position (e.g., ±190°), the reducer decelerates the slewing center through the same power transmission path.

[0009] Furthermore, the present application provides a preferred solution, in which the power ring device includes: a first power ring connected to the fixed ring of the slewing bearing, a second power ring connected to the rotating ring of the slewing bearing; and a sealing device is arranged between the first power ring and the second power ring. The main warehouse body frame is detachably connected to the slewing bearing, the slewing bearing is detachably connected to the first power ring and the second power ring, and the second power ring is detachably connected to the slewing flange. The first power ring and the second power ring provide bottom support for the fixed ring and the rotating ring of the slewing bearing respectively. These components can be assembled from the bottom up, which is convenient for workers to assemble, repair and disassemble. A sealing device is arranged between the first power ring and the second power ring, which can effectively isolate the interior of the main warehouse body frame from the external environment. The sealing device can also withstand external pressure in combination with grease.

[0010] Furthermore, the present application provides a preferred solution, which also includes: a top cover provided on the main body frame of the main warehouse; a second drag chain provided on the top cover, one end of the second drag chain is connected to the swivel center mechanism, and the other end is connected to the top cover, and the tubes and / or wires in the second drag chain are arranged inside the swivel center mechanism. One end of the second drag chain is fixedly connected to the swivel center mechanism, and the other end is fixedly connected to the top cover, and the hydraulic pipeline passes through the second drag chain provided on the top cover, and then passes through the first chamber of the swivel center mechanism to reach the actuator at the bottom of the main warehouse. Compared to placing the hydraulic pipeline in the drag chain device, placing the hydraulic pipeline in the second drag chain instead of placing it in the drag chain device together with other tubes and / or wires makes it easier to move the second drag chain and maintain the hydraulic pipeline, and can also prevent the hydraulic pipeline from contaminating other tubes and / or wires.

[0011] Furthermore, the present application provides a preferred solution in which only water pressure pipelines can be placed in the second drag chain, separating them from hydraulic pipes, grease pipes, cables and other pipes and / or wires, which is conducive to centralized management of various pipes and / or wires and prevents leakage of water pressure pipelines from causing adverse effects on other pipes and / or wires.

[0012] Furthermore, the present application provides a preferred solution, further comprising: a drag chain support mechanism fixedly connected to the top cover, wherein one end of the second drag chain is connected to the swivel center mechanism, and the other end is connected to the drag chain support mechanism. The drag chain support mechanism is fixedly connected to the top cover and is adjacent to the swivel center mechanism, and is used to support the second drag chain and limit the horizontal movement of the second drag chain. When the swivel center mechanism rotates, the second drag chain moves. Counterclockwise rotation causes a portion of the second drag chain to wrap around the swivel center mechanism. Clockwise rotation causes the second drag chain to spread out, but it cannot exceed the periphery of the drag chain support mechanism, thereby controlling the movement range of the second drag chain.

[0013] Furthermore, the present application provides a preferred solution in which the fixed ring of the slewing bearing is connected to the main frame of the main warehouse and the first power ring, the top cover is fixedly connected to the main frame of the main warehouse by bolts, the drag chain supporting mechanism is fixedly connected to the top cover by bolts, and the slewing center mechanism is rotatable relative to the top cover and the drag chain supporting mechanism.

[0014] Furthermore, the present application provides a preferred solution in which the drag chain support mechanism comprises an upper support plate and a lower support plate, which are fixedly connected to the top cover and connected by a fence. The drag chain support frame is shaped like a semicircular platform frame with a fence-like outer ring. The upper and lower support plates are steel plates, which not only control the movement range of the second drag chain but also facilitate observation and maintenance of the second drag chain.

[0015] Furthermore, the present application provides a preferred solution in which the sealing device comprises: an end face sealing device connected to the main compartment frame; a radial outer sealing device connected to the power ring device; and a lip sealing device, the lip sealing device including a sealing ring. During shaft boring machine operation, muddy water can easily enter the main compartment through the gap between the main compartment frame and the slewing bearing. The provision of a three-layer sealing device achieves a sealing effect, and the use of grease can withstand a certain pressure, thereby maintaining the stability of the main compartment.

[0016] The present application provides a shaft boring machine, characterized in that it comprises the main compartment for the shaft boring machine as described in any one of the above items.

[0017] The present application provides a main compartment and a shaft boring machine for a shaft boring machine. Compared with the prior art, the main compartment and the shaft boring machine include: a main compartment frame; a slewing mechanism connected to the main compartment frame via a slewing bearing, the slewing mechanism including a slewing center mechanism, a slewing flange connected to the slewing center mechanism, and a power ring device connecting the slewing flange and the slewing bearing; a drag chain device, one end of the drag chain device is connected to the slewing center mechanism and the other end is connected to the main compartment frame, and the tubes and / or wires in the drag chain device are arranged inside the slewing center mechanism; a sealing device connected to the main compartment frame and the slewing bearing, the sealing device including a plurality of sealing structures arranged in sequence from the main compartment frame to the slewing bearing. When the slewing bearing rotates, the fixed ring is connected to the main compartment frame and remains stationary, and the rotating ring transmits power to the power ring device through the power ring device, the power ring device is connected to the slewing flange, and the slewing flange drives the slewing center mechanism to rotate. Pipes and / or wires, such as hydraulic lines, cables, hydraulic lines, and grease lines, are arranged in a drag chain device and pass through the interior of a slewing center mechanism to an actuator at the bottom of the main compartment. When the slewing center mechanism rotates, the end of the drag chain device connected to the slewing center mechanism rotates accordingly, while the end of the drag chain device connected to the main compartment frame remains stationary. Horizontal pipes and / or wires are centrally managed by the drag chain device, while vertical pipes and / or wires are centrally managed by the slewing center mechanism. This structure facilitates centralized management of pipes and / or wires, is compact, and is more convenient to operate when pipes and / or wires need to be repaired or replaced, thereby improving work efficiency. The sealing device achieves a sealing effect through an end face seal, a radial outer seal, and a lip seal. At the same time, it can withstand a certain pressure when combined with the use of grease, ensuring sealing performance and improving pipe and / or wire management efficiency without affecting the slewing motion. The main compartment and shaft boring machine provided in this application solve the problems of the existing main compartment in the prior art, such as the chaotic distribution of pipes and wires, which makes management and maintenance inconvenient.

[0029] like Figures 1-4As shown, the embodiment of the present application provides a main chamber for a shaft boring machine and a shaft boring machine, which, compared with the prior art, includes: a main chamber body frame; a slewing mechanism connected to the main chamber body frame via a slewing bearing, the slewing mechanism including a slewing center mechanism, a slewing flange connected to the slewing center mechanism, and a power ring device connecting the slewing flange and the slewing bearing; a drag chain device, one end of the drag chain device is connected to the slewing center mechanism and the other end is connected to the main chamber body frame, and the tubes and / or wires in the drag chain device are arranged inside the slewing center mechanism; a sealing device, connected to the main chamber body frame and the slewing bearing, and the sealing device includes a plurality of sealing structures arranged in sequence from the main chamber body frame to the slewing bearing. When the slewing bearing rotates, the fixed ring is connected to the main chamber body frame and remains stationary, and the rotating ring transmits power to the power ring device through the power ring device, the power ring device is connected to the slewing flange, and the slewing flange drives the slewing center mechanism to rotate. Water pressure pipes, cables, hydraulic pipes, grease pipes, and other pipes and / or wires are arranged in the drag chain device and pass through the interior of the slewing center mechanism to reach the actuator at the bottom of the main warehouse. When the slewing center mechanism rotates, the end of the drag chain device connected to the slewing center mechanism rotates accordingly, and the end of the drag chain device connected to the main frame of the main warehouse is fixed. The horizontal pipes and / or wires are centrally managed by the drag chain device, and the vertical pipes and / or wires are centrally managed by the slewing center mechanism. This structure facilitates the centralized management of pipes and / or wires and is compact. When the pipes and / or wires need to be repaired or replaced, it is more convenient to operate and can improve work efficiency. The sealing device achieves the sealing effect through an end face seal, a radial outer seal, and a lip seal. At the same time, it can withstand a certain pressure in conjunction with the use of grease, ensuring sealing performance and improving the management efficiency of pipes and / or wires without affecting the rotational motion.

[0030] The system also includes a drag chain guide mechanism, which is arranged around the rotation center mechanism without closing. The drag chain guide mechanism includes a guide plate and a bracket, which is connected to the main frame of the main compartment. The guide plate of the drag chain guide mechanism is a component with an arc-shaped cross-section, which is used to guide the drag chain device around the rotation center mechanism and rotate with it. This limits the movement of the drag chain device during rotation and prevents it from moving outside the designated area of ​​the drag chain guide mechanism to avoid affecting the operation of other structures. The drag chain guide mechanism serves as a guide and avoidance mechanism.

[0031] The slewing center mechanism comprises a first chamber and a second chamber. The second chamber is within the first chamber. The pipes and / or wires in the drag chain assembly are arranged inside the first chamber and outside the second chamber. The cables, hydraulic lines, grease lines, and hydraulic lines connected to the actuator at the bottom of the main compartment are inserted through the first chamber of the slewing center mechanism at one end and secured by the drag chain assembly. The other end is secured to the actuator. Without passing through the first chamber, the pipes and / or wires would be threaded directly through the slewing flange, leaving them hanging in the middle. This creates a messy and difficult-to-manage appearance. The second chamber is exposed to muddy water. Mud from the well is pumped into the second chamber by the actuator and discharged through the first chamber. Hydraulic pipes, mud pipes, cables, grease lines, hydraulic lines, and other pipes and / or wires can be connected to the actuator from the first chamber. The second chamber serves as a mud channel for the actuator's pump to pump mud to the surface.

[0032] The system also includes a motor and a reducer connected to the slewing bearing. The motor provides power to rotate the slewing bearing, which in turn drives the corresponding power ring device, the slewing flange connected to the power ring device, and the slewing center mechanism connected to the slewing flange. When the slewing center mechanism is about to rotate to a preset position (e.g., ±190°), the reducer decelerates the slewing center through the same power transmission path.

[0033] The power ring device includes: a first power ring connected to the fixed ring of the slewing bearing, a second power ring connected to the rotating ring of the slewing bearing; and a sealing device is arranged between the first power ring and the second power ring. The main frame of the main warehouse is detachably connected to the slewing bearing, the slewing bearing is detachably connected to the first power ring and the second power ring, and the second power ring is detachably connected to the slewing flange. The first power ring and the second power ring provide bottom support for the fixed ring and the rotating ring of the slewing bearing, respectively. These components can be assembled from the bottom up, making it convenient for workers to assemble, repair, and disassemble. A sealing device is arranged between the first power ring and the second power ring to effectively isolate the interior of the main frame of the main warehouse from the external environment. The sealing device can also withstand external pressure when combined with grease.

[0034] It also includes: a top cover arranged on the main body frame of the main warehouse; a second drag chain arranged on the top cover, one end of the second drag chain is connected to the rotation center mechanism, and the other end is connected to the top cover, and the tubes and / or wires in the second drag chain are arranged inside the rotation center mechanism. One end of the second drag chain is fixedly connected to the rotation center mechanism, and the other end is fixedly connected to the top cover. The hydraulic pipeline passes through the second drag chain arranged on the top cover, and then passes through the first chamber of the rotation center mechanism to reach the actuator at the bottom of the main warehouse. Compared to placing the hydraulic pipeline in the drag chain device, placing the hydraulic pipeline in the second drag chain instead of placing it in the drag chain device with other tubes and / or wires makes it easier to move the second drag chain and maintain the hydraulic pipeline, and can also prevent the hydraulic pipeline from contaminating other tubes and / or wires.

[0035] Specifically, only the water pressure pipeline can be placed in the second drag chain, which is separated from hydraulic pipes, grease pipes, cables and other pipes and / or wires, which is conducive to centralized management of various pipes and / or wires and prevents leakage of the water pressure pipeline from causing adverse effects on other pipes and / or wires.

[0036] The device further includes a drag chain support mechanism fixedly connected to the top cover, wherein one end of the second drag chain is connected to the swivel center mechanism and the other end is connected to the drag chain support mechanism. The drag chain support mechanism is fixedly connected to the top cover and adjacent to the swivel center mechanism, and is used to support the second drag chain and limit the horizontal movement of the second drag chain. When the swivel center mechanism rotates, it drives the second drag chain to move. Counterclockwise rotation causes a portion of the second drag chain to wrap around the swivel center mechanism. Clockwise rotation causes the second drag chain to spread out, but it cannot exceed the periphery of the drag chain support mechanism, thus controlling the movement range of the second drag chain.

[0037] Specifically, the fixed ring of the slewing bearing is connected to the main frame of the main warehouse and the first power ring, the top cover is fixedly connected to the main frame of the main warehouse by bolts, the drag chain supporting mechanism is fixedly connected to the top cover by bolts, and the slewing center mechanism is rotatable relative to the top cover and the drag chain supporting mechanism.

[0038] The drag chain support mechanism includes upper and lower support plates, which are fixedly connected to the top cover and connected by a fence. The drag chain support frame is a semicircular platform frame with a fence-like outer ring. The upper and lower support plates are steel plates, which not only control the movement range of the second drag chain but also facilitate observation and maintenance of the second drag chain.

[0039] The sealing device includes an end-face seal connected to the main compartment frame; a radial outer seal connected to the power ring; and a lip seal, which includes a sealing ring. During shaft boring machine operation, mud and water can easily enter the main compartment through the gap between the main compartment frame and the slewing bearing. This three-layer sealing system achieves a sealed seal, and combined with the use of grease, it can withstand a certain amount of pressure, maintaining internal stability within the main compartment.
