Description

Technical Field

[0001] The utility model relates to the technical field of a digging, anchoring and protecting integrated machine, in particular, to a waterway system of the digging, anchoring and protecting integrated machine, and in addition, particularly to a digging, anchoring and protecting integrated machine adopting the waterway system. Background Art

[0002] The main functions of the existing integrated tunnel boring machine water system include spraying and cooling. The water entering the tunnel is divided into two ways after passing through the filter, one for internal spraying, and the other for external spraying after decompression, cooling the hydraulic oil and the motor. The integrated tunnel boring and anchoring machine is upgraded on the basis of the existing integrated tunnel boring machine, and its water system has added a new function: slag discharge. Therefore, the integrated tunnel boring and anchoring machine water system needs to be improved on the basis of the integrated tunnel boring machine water system to meet the demand for slag discharge water. In addition, since the existing integrated tunnel boring and anchoring machine water system adopts the mode of connecting the external spray water circuit and the cooling water circuit in series, when the flow rate of the series water circuit is too large, it is beneficial to the cooling of the motor and hydraulic oil. However, if the flow rate of the external spray is too large, water will accumulate on the front face, and the slag will become viscous after mixing with water, resulting in difficulty in discharging, chain jamming, etc., reducing the working efficiency of the integrated tunnel boring and anchoring machine. When the flow rate of the series water circuit is too small, the insufficient cooling of the motor and hydraulic oil will affect the cooling and heat dissipation of the equipment, and even cause automatic shutdown, which will also reduce the working efficiency of the integrated tunnel boring and anchoring machine. In addition, the excavation, anchoring and protection machine needs to turn on the spray during the excavation process, and turn off the spray during the anchoring and protection process. At present, the water channel switching in the two modes is usually manually controlled by a manual ball valve, and it is difficult to ensure the timeliness of the water channel switching. If the water channel is not switched in time or the spray is forgotten to be turned off during the anchoring and protection process, insufficient water during the drilling process of the drilling rig can easily cause the drill to get stuck, greatly affecting work efficiency.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Reference Figure 1 The preferred embodiment of the present application provides a water system of an integrated mining, anchoring and guarding machine, including an inlet waterway 1, a cooling waterway 2, a slag discharge waterway 3, a spray waterway 4, a first diverter element 5 and a drain valve 6. The inlet waterway 1 is connected to the cooling waterway 2, the cooling waterway 2 is connected to the first diverter element 5, the first diverter element 5 is used to divert the cooling water output by the cooling waterway 2, the slag discharge waterway 3, the spray waterway 4 and the drain valve 6 are all connected to the first diverter element 5, and the drain valve 6 is connected to the tunnel drainage system to adjust the drainage volume. Among them, the first diverter element 5 can be a collecting and diverting valve or a diverting block, and the drain valve 6 is preferably an electrically controlled regulating valve, such as an electrically controlled ball valve.

[0024] It can be understood that in the water system of the integrated digging, anchoring and protection machine of this embodiment, the water entering the tunnel first enters the cooling water channel 2 through the water inlet water channel 1. After cooling the hydraulic oil and the motor, the cooling water is then diverted to the slag discharge water channel 3, the spray water channel 4 and the drain valve 6 through the first diversion element 5. Since the slag discharge water channel 3, the spray water channel 4 and the drain water channel are connected in parallel and then in series with the cooling water channel 2, the total water consumption can be effectively reduced, and the utilization rate of cooling water can be improved. The flow rate of cooling water diverted to the slag discharge water channel 3 or the spray water channel 4 can also be adjusted by controlling the opening of the drain valve 6. While increasing the cooling water volume to improve the cooling effect, the spray flow rate can be reduced to avoid water accumulation on the front face, thereby improving the working efficiency of the integrated digging, anchoring and protection machine. For example, when performing excavation operations, the opening of the drain valve 6 can be increased, and most of the cooling water can be discharged into the tunnel drainage system through the drain valve 6, and a small part of the cooling water can be sprayed out through the spray water channel 4. When performing anchoring operations, the opening of the drain valve 6 can be reduced, and a small part of the cooling water can be discharged into the tunnel drainage system through the drain valve 6, and most of the cooling water can be transported to the anchor machine through the slag discharge water channel 3 for slag discharge.

[0025] It can be understood that the water inlet circuit 1 includes a water inlet valve 11, a filter 12, a first pressure gauge 13, a first pressure reducing valve 14 and a first safety valve 15 which are sequentially arranged along the water inlet direction of the pipeline, the first pressure reducing valve 14 is connected to the cooling water circuit 2, and the first safety valve 15 is connected to the tunnel drainage system. Among them, the water inlet valve 11 is used to control the water inlet of the whole machine, preferably a ball valve, the filter 12 is used to filter the tunnel inlet water to meet the cleanliness requirements of cooling water and spray water, the first pressure gauge 13 is used to monitor the tunnel inlet pressure, the first pressure reducing valve 14 is used to reduce the tunnel inlet pressure to meet the water pressure requirements of the cooling water circuit 2, and the first safety valve 15 is used to limit the water pressure of the cooling water circuit 2 to prevent overpressure from damaging components.

[0026] In addition, the cooling water circuit 2 includes a first cooler 21, a second diverter element 22, a first water regulating valve 23, a second water regulating valve 24, a third water regulating valve 25, a second cooler 26, a cutting motor 27 and an oil pump motor 28. The water inlet of the first cooler 21 is connected to the water inlet circuit 1, and the water outlet is connected to the second diverter element 22. The cooling water output by the second diverter element 22 is divided into three paths, the first path is transported to the second cooler 26 through the first water regulating valve 23, the second path is transported to the cutting motor 27 through the second water regulating valve 24, and the third path is transported to the oil pump motor 28 through the third water regulating valve 25. The second cooler 26, the cutting motor 27 and the oil pump motor 28 are all connected to the first diverter element 5. The second diverter element 22 is the same as the first diverter element 5, and a collecting and diverting valve or a diverter block can be used. The first cooler 21 is used to cool the hydraulic oil of the hydraulic system. The first water regulating valve 23, the second water regulating valve 24, and the third water regulating valve 25 are used to control the water intake of the second cooler 26, the cutting motor 27, and the oil pump motor 28, respectively. A regulating valve or a stop valve can be used. The second cooler 26 is used to cool the gear oil of the cutting head. In addition, the cooling water circuit 2 also includes a second pressure gauge 29 for monitoring the cooling water pressure. The second pressure gauge 29 is installed on the second diverter element 22. Among them, the first water regulating valve 23, the second water regulating valve 24, and the third water regulating valve 25 can be electromagnetic regulating valves or stop valves. Considering that the regulation accuracy requirement in this water circuit system is not high, it is preferred to use a stop valve.

[0027] In addition, the slag discharge waterway 3 includes a fourth water regulating valve 31, a fifth water regulating valve 32, a first hydraulically controlled one-way valve 33 and a second hydraulically controlled one-way valve 34. The fourth water regulating valve 31 is connected to the first diverter element 5 and the first hydraulically controlled one-way valve 33, respectively. The fifth water regulating valve 32 is connected to the first diverter element 5 and the second hydraulically controlled one-way valve 34, respectively. The first hydraulically controlled one-way valve 33 is connected to the left anchor bolter, and the second hydraulically controlled one-way valve 34 is connected to the right anchor bolter. The control ports of the first hydraulically controlled one-way valve 33 and the second hydraulically controlled one-way valve 34 are connected to the propulsion cylinder A ports of the left and right anchor bolters, respectively. The fourth water regulating valve 31 is used to adjust the water inflow of the left anchor bolter, the fifth water regulating valve 32 is used to adjust the water inflow of the right anchor bolter, the first hydraulically controlled one-way valve 33 is used to control the water inflow of the left anchor bolter, and the second hydraulically controlled one-way valve 34 is used to control the water inflow of the right anchor bolter. The fourth water regulating valve 31 and the fifth water regulating valve 32 may be electromagnetic regulating valves or stop valves. Considering that the regulation accuracy requirement in the water system is not high, stop valves are preferably used.

[0028] It can be understood that when the integrated digging, anchoring and protecting machine is switched to the anchoring and protecting mode, the bolter propulsion cylinder A port is filled with oil, and the pressure oil is simultaneously delivered to the control ports of the first hydraulically controlled one-way valve 33 and the second hydraulically controlled one-way valve 34, and the first hydraulically controlled one-way valve 33 and the second hydraulically controlled one-way valve 34 are controlled to be bidirectionally connected, so as to deliver cooling water to the left bolter and the right bolter to meet the demand for slag water, and the water flow rate can be adjusted by the fourth water regulating valve 31 and the fifth water regulating valve 32. When the integrated digging, anchoring and protecting machine is switched to the excavation mode, the bolter propulsion cylinder A port stops receiving oil, and there is no pressure oil input to the control ports of the first hydraulically controlled one-way valve 33 and the second hydraulically controlled one-way valve 34, and the first hydraulically controlled one-way valve 33 and the second hydraulically controlled one-way valve 34 are only unidirectionally connected, so that cooling water cannot be delivered to the left bolter and the right bolter. Therefore, the slag water channel 3 realizes the linkage control of the excavation operation and the slag water supply by connecting the control ports of the two hydraulically controlled one-way valves to the A port of the thrust cylinder, and can automatically control the supply of the slag water.

[0029] Optionally, the slag discharge water circuit 3 also includes a first ball valve 35 arranged in parallel with the first hydraulically controlled one-way valve 33 and a second ball valve 36 arranged in parallel with the second hydraulically controlled one-way valve 34. When the first hydraulically controlled one-way valve 33 fails, the first ball valve 35 can be opened to ensure the slag discharge water supply to the left anchor bolter. When the second hydraulically controlled one-way valve 34 fails, the second ball valve 36 can be opened to ensure the slag discharge water supply to the right anchor bolter.

[0030] In addition, the spray water circuit 4 includes a second pressure reducing valve 41, a second safety valve 42, a high-pressure water pump 43 and a third hydraulically controlled one-way valve 44 which are sequentially arranged along the water inlet direction of the pipeline, the second safety valve 42 is connected to the tunnel drainage system, the control port of the third hydraulically controlled one-way valve 44 is connected to the A port of the water pump motor of the high-pressure water pump 43, and the third hydraulically controlled one-way valve 44 is connected to the spray rack. Among them, the second pressure reducing valve 41 is used to reduce the water pressure to protect the high-pressure water pump 43, the second safety valve 42 is used to limit the water inlet pressure of the high-pressure water pump 43 to prevent overpressure from damaging components, the high-pressure water pump 43 is used to pressurize the cooling water to ensure the spray pressure, the control port of the third hydraulically controlled one-way valve 44 is connected to the water pump motor A port of the high-pressure water pump 43, when the excavation, anchoring and protection integrated machine is switched to the excavation mode, the high-pressure water pump 43 is controlled to be turned on, the water pump motor A port is filled with oil, and the pressure oil is simultaneously delivered to the control port of the third hydraulically controlled one-way valve 44, and the third hydraulically controlled one-way valve 44 is controlled to be bidirectionally conductive. At this time, the cooling water is delivered to the spray rack through the third hydraulically controlled one-way valve 44 for spraying operation, and when the excavation, anchoring and protection integrated machine is switched to the anchoring protection mode, the high-pressure water pump 43 is controlled to be turned off, the water pump motor A port stops filling with oil, and the control port of the third hydraulically controlled one-way valve 44 is switched to unidirectionally conductive due to the lack of pressure oil input. At this time, the cooling water cannot be delivered to the spray rack, and the spray function is closed. It can be understood that the spray water circuit 4 realizes synchronous control of the water pump and the spray by connecting the control port of the third hydraulically controlled one-way valve 44 with the water pump motor A port of the high-pressure water pump 43. The spray automatically turns on when the water pump is turned on, and automatically turns off when the water pump is turned off, thereby realizing automatic switching of the spray state in the excavation mode and the anchor protection mode, avoiding drill jamming due to excessive water on the head surface or insufficient slag water due to untimely switching.

[0031] Optionally, the spray water circuit 4 also includes a third safety valve 45 arranged between the high-pressure water pump 43 and the third hydraulically controlled one-way valve 44. When the third hydraulically controlled one-way valve 44 is damaged, the pressure can be relieved through the third safety valve 45 to prevent the outlet of the high-pressure water pump 43 from accumulating high pressure and damaging components.

[0032] Optionally, the spray water circuit 4 further includes a temperature sensor 46 disposed before the high-pressure water pump 43, which automatically stops starting the high-pressure water pump 43 when the temperature is too high, to prevent the internal seal of the high-pressure water pump 43 from being damaged in a high-temperature environment.

[0033] Optionally, the spray water circuit 4 further includes a pressure sensor 47 disposed before the high-pressure water pump 43, which automatically stops starting the high-pressure water pump 43 when the pressure is too low, to prevent the high-pressure water pump 43 from being damaged due to long-term vacuum operation.

[0034] Optionally, the spray water circuit 4 further includes a sixth water volume regulating valve 48 disposed after the third hydraulically controlled one-way valve 44, for regulating the spray water flow rate. The sixth water volume regulating valve 48 may be an electromagnetic regulating valve or a stop valve. Considering that the regulation accuracy requirement in the water circuit system is not high, a stop valve is preferably used. In addition, the spray water circuit 4 further includes a third pressure gauge 49 disposed after the third hydraulically controlled one-way valve 44, for monitoring the pressure of the spray system.

[0035] In addition, another embodiment of the utility model further provides an integrated digging, anchoring and protecting machine, which preferably adopts the waterway system as described above.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
