Description

Technical Field

[0001] The present application relates to the technical field of tunnel boring machines, and in particular to a tunnel boring machine hydraulic system and a tunnel boring machine with an interlocking function. Background Art

[0002] The existing tunnel boring machine system is generally a load-sensitive system, which has the advantages of high efficiency and load flow not being affected by the load size. When the beam supporter is in motion, in order to meet safety requirements, the beam supporter action needs to be interlocked with the star wheel and scraper conveyor action, rather than interlocked with the entire machine action. At present, the existing locking circuit puts the locking function valve on the actuator telescopic circuit, and uses the pilot circuit to control the on and off of the locking function valve and cut off the LS (Load Sensing) feedback oil circuit to achieve the locking function. It can be adapted for coal and rock models, but for hard rock models, switching the LS pipeline will affect the action of actuators such as water pumps and shovels, and there is no telescopic cylinder circuit, so the beam supporter function cannot draw oil.

[0007] According to the hydraulic system of a tunnel boring machine with an interlocking function provided by the present application, the hydraulic system of a tunnel boring machine with an interlocking function includes a remote control locking valve of the whole machine, a hydraulic control handle of the whole machine, a manual locking valve, a remote control locking valve of a star-wheel scraper conveyor, a hydraulic control handle of the star-wheel scraper conveyor, an electronic control system and a locking valve of a beam supporter. The remote control locking valve of the whole machine is used to be connected to a pilot oil source. The hydraulic control handle of the whole machine is connected to the remote control locking valve of the whole machine. The manual locking valve is connected to a pilot oil source. The remote control locking valve of the star-wheel scraper conveyor is connected to the manual locking valve. The hydraulic control handle of the star-wheel scraper conveyor is connected to the remote control locking valve of the star-wheel scraper conveyor. The electronic control system is respectively connected to the remote control locking valve of the whole machine and the remote control locking valve of the star-wheel scraper conveyor, and is used to control the reversing of the remote control locking valve of the whole machine and the remote control locking valve of the star-wheel scraper conveyor. The locking valve of the beam supporter is connected to the manual locking valve. Among them, the manual locking valve includes a first oil inlet, a first working oil port, a second working oil port and a first oil return port. The first working oil port is connected to the remote control locking valve of the planetary scraper conveyor, and the second working oil port is connected to the locking valve of the beam support device. When the manual locking valve is in the working condition of the tunnel boring machine, the first oil inlet is connected to the first working oil port, and the second working oil port is connected to the first oil return port.

[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, according to a specific embodiment of the tunnel boring machine hydraulic system 10 with an interlocking function proposed in the present application, a pilot circuit is used to control the on-off of the locking function valve to realize the locking function of the beam supporter and the star wheel.

[0053] Specifically, Figure 1 As shown, when the manual locking valve 130 is in the working condition of the tunnel boring machine, the hydraulic oil passes through the pilot oil source Pi, through the second oil inlet 112 (P2 port) and the third working oil port 114 (A2 port) of the remote control locking valve 110 of the whole machine, and enters the oil inlet (P4 port) of the hydraulic control handle 120 of the whole machine, and passes through the third oil inlet 142 (P3 port) and the fifth working oil port 144 (A3 port) of the remote control locking valve 140 of the star-wheel scraper conveyor, and enters the oil inlet (P5 port) of the hydraulic control handle 150 of the star-wheel scraper conveyor, and respectively operates the hydraulic control handle 120 of the whole machine and the hydraulic control handle 150 of the star-wheel scraper conveyor, so as to activate each actuator of the whole machine and the star-wheel conveyor. At this time, if the whole machine has a remote control requirement, the electronic control system 160 can simultaneously control the whole machine remote control locking valve 110 and the reversing of the star wheel first operation locking valve, cut off the pilot oil of the whole machine hydraulic control handle 120 and the star wheel scraper conveyor hydraulic control handle 150, and achieve remote control and non-remote control locking effects.

[0054] At the same time, since the hydraulic control oil of the beam support device locking valve 170 returns to the oil tank 220 through the second working oil port 136 (B1 port) and the first return oil port 138 (T1 port) of the manual locking valve 130, the beam support device locking valve 170 is in a closed state, and the beam support device cannot work, thereby achieving the locking effect of the entire machine and the beam support device.

[0055] When the pressure sensor 180 detects the pilot oil pressure of the beam support locking valve 170, it determines that the beam support is in working state, and controls the hydraulic control reversing valve 190 through the electronic control system 160 to close the hydraulic control water valve 210 and stop the cutting motor at the same time, so as to achieve the function of automatically closing the spray inside and outside the cutting part when the beam support is in working state.

[0056] Among them, a1, a2, a3, a4, a5, a6, a7, a10, a11, b1, b2, b3, b4, b5, b6, b7, b10, and b11 are respectively the working oil ports for the actions of the various actuators of the whole machine hydraulic control handle 120 and the star wheel scraper conveyor hydraulic control handle 150.

[0057] Alternative way:

[0058] The beam support locking valve 170 and the beam support reversing valve can be integrated together.

[0059] The hydraulically controlled reversing valve 190 and the hydraulically controlled water valve 210 can be integrated.

[0060] The whole machine remote control locking valve 110 and the star wheel scraper conveyor remote control locking valve 140 can be integrated together.

[0061] In summary, the beneficial effects of the embodiments of the present application are:

[0062] 1. The beam support device can be interlocked with the whole machine.

[0063] 2. The beam support device and the cutting motor as well as the internal and external spray of the cutting machine can be automatically turned off.

[0064] 3. The valve assembly is divided into 2 groups and can be controlled separately.
