Description

Technical Field

[0001] This utility model relates to the field of engineering construction equipment technology, specifically to an automatic lubrication system for an integrated drilling, injection, and anchoring machine. Background Technology

[0002] The drilling-grouting-anchoring integrated machine is an engineering machinery device that integrates drilling, grouting, and anchoring, and is widely used in tunnel excavation, slope reinforcement, foundation treatment, and other fields. Due to the complex operating environment and heavy workload, especially in extremely complex construction environments such as high-altitude tunnels, the operational capabilities of both manual and mechanical personnel are severely reduced. The moving parts of the drilling-grouting-anchoring integrated machine frequently face high loads and high wear challenges, requiring frequent lubrication maintenance to ensure normal operation and extend service life. However, current lubrication methods mainly rely on manual periodic inspections and manual oiling, which is not only labor-intensive but also difficult to guarantee in a timely and accurate manner. Furthermore, uneven lubrication, insufficient lubrication, or over-lubrication can easily lead to equipment damage and reduced work efficiency, thereby increasing project time and costs.

[0003] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Utility Model Content

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0031] Furthermore, in the description of this utility model, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Of course, such terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than those illustrated or described herein.

[0032] It should also be noted that although the order of steps is mentioned in the method description, in some cases, steps may be performed in a different order than that described here, and this should not be interpreted as a restriction on the order of steps.

[0033] Common drilling-grouting-anchoring integrated machines in engineering construction typically consist of three parts: the vehicle body, the anchor bolt working arm, and the suspended platform working arm. They generally include major components such as a propulsion beam, a slewing beam, the anchor bolt working arm, and the suspended platform arm, all mounted on the vehicle body. This invention provides an automatic lubrication system for drilling-grouting-anchoring integrated machines. Deployed on existing machines, it automatically and precisely lubricates designated lubrication points, solving the problems of low efficiency and poor timeliness of manual lubrication in existing technologies, thereby improving the equipment's service life and working efficiency.

[0034] like Figure 1 The system includes a controller, a lubricating oil storage device, a flow meter, a lubricating oil pump, a pressure sensor, a lubricating oil distributor, a solenoid valve, a lubricating oil delivery pipeline, and various lubrication points of the drilling, injection, and anchoring machine. Each lubrication point is equipped with a lubrication point temperature sensor.

[0035] The lubricating oil storage device, located at the tail of the drilling, injection, and anchoring machine, is a device for storing lubricating oil and has the necessary input, output, and inspection ports.

[0036] The output of the lubricating oil storage device is connected to the lubricating oil distributor via a lubricating oil delivery pipeline. The output of the lubricating oil distributor branches out and extends to various lubrication points of the integrated drilling, injection, and anchoring machine via lubricating oil delivery pipelines. A lubricating oil pump is located at the output of the lubricating oil storage device. Temperature sensors for each lubrication point are deployed at each lubrication point of the integrated drilling, injection, and anchoring machine. These temperature sensors are connected to the controller and send temperature information from each lubrication point. The controller connects to and controls the lubricating oil pump. When the temperature sensor detects that the temperature at a lubrication point is too high, it indicates severe friction and the need for lubrication. The controller then activates the lubricating oil pump, delivering lubricating oil from the lubricating oil storage device to the lubrication point.

[0037] Furthermore, solenoid valves are installed on the lubricating oil delivery pipelines of each branch at the output end of the lubricating oil distributor, and the controller is connected to and controls the solenoid valves. Each solenoid valve is located at a lubrication point on a lubricating oil delivery pipeline, and the controller achieves lubrication operation at the designated lubrication point by precisely controlling the solenoid valves.

[0038] A flow meter is installed on the lubricating oil delivery pipeline between the lubricating oil reservoir and the lubricating oil pump. The flow meter is connected to the controller and sends flow information from the output of the lubricating oil reservoir. A pressure sensor is installed on the lubricating oil delivery pipeline between the lubricating oil pump and the lubricating oil distributor. The pressure sensor is connected to the controller and sends pressure information from the output of the lubricating oil pump.

[0039] Simultaneously, the lubricating oil storage device is equipped with a storage temperature sensor, which connects to the controller and sends the temperature information of the lubricating oil within the storage device. The lubricating oil storage device is also equipped with a heating device, which is connected to and controlled by the controller. The lubricating oil delivered to the lubrication point needs to maintain a certain temperature. When the ambient temperature is too low, the lubricating oil temperature will drop, failing to meet lubrication requirements. When the storage temperature sensor detects that the lubricating oil temperature in the storage device is too low, the controller activates the heating device to heat the lubricating oil until the required temperature is reached, automatically controlling it to maintain a reasonable temperature. This achieves the purpose of controlling the lubricating oil viscosity and improving lubrication effect, making it particularly suitable for machinery used in cold regions (and during cold periods).

[0040] In addition, the lubricating oil storage tank is equipped with an oil level sensor. The oil level sensor is connected to the controller and sends the oil level information of the lubricating oil in the storage tank. The controller is connected to an oil level warning light and controls the oil level warning light to flash when the oil level in the storage tank is lower than the standard value. When the warning light flashes, it reminds the staff to add lubricating oil in time to avoid interruption of lubrication operation.

[0041] The aforementioned storage temperature sensor, oil level sensor, etc., are all lubricating oil storage monitoring devices used to monitor key information about the lubricating oil status in the storage, including but not limited to oil temperature, oil level, oil pressure, and oil quality, to ensure that the lubricating oil is delivered to each lubrication point under ideal conditions.

[0042] The drilling, injection, and anchoring machine is equipped with lubrication point flow sensors on the lubrication oil delivery pipelines at each lubrication point. These flow sensors are connected to the controller and transmit flow information from the input terminals of each lubrication point. Similarly, the drilling, injection, and anchoring machine is also equipped with lubrication point pressure sensors on the lubrication oil delivery pipelines at each lubrication point. These pressure sensors are connected to the controller and transmit pressure information from the input terminals of each lubrication point. The controller receives this flow and pressure information, allowing it to monitor the lubrication oil delivery status in a timely manner.

[0043] Ideally, the lubricating oil flows sequentially through a flow meter, lubricating oil pump, pressure sensor, lubricating oil distributor, and solenoid valve to each lubrication point of the integrated anchor drilling and injection machine. The flow meter can be a vortex flow meter, gear flow meter, or balanced flow meter, etc., with the specific model and specifications selected based on the lubricating oil's performance and application scenario, used to monitor lubricating oil consumption. The lubricating oil pump delivers the lubricating oil to each lubrication point. The pressure sensor measures the pressure at the lubricating oil pump's outlet and feeds it back to the controller. The controller controls the lubricating oil pump's outlet pressure to ensure rapid delivery of lubricating oil to each lubrication point. The lubricating oil distributor connects the lubricating oil pump to each lubrication point, distributing the lubricating oil to the delivery pipelines at each lubrication point. Solenoid valves installed on the lubrication pipelines control the flow rate and direction of the lubricating oil. The controller receives sensor data and controls the operating status of the heating system, lubricating oil pump, and solenoid valves.

[0044] In addition, this utility model can also be equipped with a touch screen display, which can not only display the working status of the lubrication system, lubricating oil parameters and oil reservoir parameters in real time, but also allow manual touch control of a specific lubrication point for targeted lubrication.

[0045] In this embodiment, lubrication points are deployed on the propulsion beam, slewing beam, anchor bolt working arm, basket arm, and vehicle body of the drilling-injection-anchoring integrated machine, mainly including some hinged parts and moving parts.

[0046] like Figure 2 The lubrication points of the propulsion beam include: 2 lubrication points of the first tail coiling pipe 11, 4 compensating cylinder pins 12, anchor injection power head gearbox 13, bearing at the anchor bolt drive box 14, 4 clamping manipulators 15, 2 driving wire pulleys 16, 2 anchor bolt support bearings 17, 4 guiding manipulators 18, and 2 front guide clamping cylinders 19.

[0047] like Figure 3The lubrication points of the slewing beam include: 2 lubrication points 21 for the second tail coil, 2 lubrication points 22 for the rear swing cylinder pins, 23 lubrication points 24 for the slewing reducer, 25 lubrication points 26 for the front support bearing of the propulsion beam, and 27 for the front swing cylinder pins.

[0048] like Figure 4 The lubrication points of the anchor bolt working arm include: lubrication point 31 of the first main arm cross joint, 32 of the first support arm cylinder cross joint at 2 locations, lubrication point 33 of the first main arm hinge pin, 34 of the first support arm cylinder pin at 4 locations, 35 of the main arm telescopic slider at 8 locations, 36 of the first follower cylinder pin at 4 locations, 37 of the first follower cross joint at 2 locations, and pin at the front end of the main arm at 38.

[0049] like Figure 5 The lubrication points of the suspended platform arm include: the second main arm cross lubrication point 41, the second support arm cylinder cross lubrication point 42, the second main arm hinge pin lubrication point 43, the second support arm cylinder pin 44, the first-level arm telescopic slider 8, the second-level arm telescopic slider 46, the second-level arm telescopic cylinder pin 2, the second-level arm telescopic cylinder pin 47, the second follower cylinder pin 48, the second follower cross lubrication point 49, and the second-level arm cross lubrication point 410.

[0050] The lubrication points of the vehicle body include: the aerosol lubricating oil point of the pneumatic water valve, the grease lubricating oil point of the rear axle swing frame, the aerosol lubricating oil point of the rock drilling system, the grease lubricating oil point of the steering cylinder joint (4 points), the grease lubricating oil point of the frame hinge pin (2 points), the grease lubricating oil point of the front outrigger slider (8 points), and the grease lubricating oil point of the front and rear outrigger cylinder foot plates (4 points).

[0051] like Figure 6 The system of this invention can perform precise lubrication control based on existing PID algorithms, specifically including the following steps:

[0052] Step 1: First, initialize the system, and feed back the pressure, flow and temperature data collected at the lubrication points to the controller;

[0053] Step 2: Determine the lubrication status of the lubrication point based on the temperature data. If the temperature value of the lubrication point is higher than the preset value, it means that there is a lack of lubrication, and the solenoid valve will open. Otherwise, lubrication is not required.

[0054] Step 3: Sensors deployed in the lubricating oil reservoir detect the reservoir's status. If the lubricating oil is in an ideal state, the lubricating oil pump starts; otherwise, the heating device starts until the ideal state is reached, at which point the lubricating oil pump starts again and delivers the lubricating oil to the lubricating oil delivery pipeline.

[0055] Step 4: If lubrication is required at this point, the controller controls the corresponding solenoid valve to open and calculates the error between the lubricating oil status data (pressure, flow, temperature) and the set value in real time. The PID algorithm controller generates a control signal based on the error and autonomously adjusts and controls the working state of the lubricating oil pump and solenoid valve to achieve precise control of the supply and distribution of lubricating oil, avoid over-lubrication or under-lubrication of the anchor drilling and injection machine, and ensure the long-term stable operation of the equipment.

[0056] Step 5: When the monitored lubrication flow rate is higher than the preset value, the system automatically controls the state of the solenoid valve to reduce or stop the supply of lubricating oil and prevent excessive waste of lubricating oil;

[0057] Step Six: When all solenoid valves are closed, it is determined that all lubrication points of the integrated anchor drill string machine have been fully lubricated, the lubrication system automatically shuts off, and lubrication ends.

[0058] Compared to traditional manual lubrication, this invention offers a high degree of automation, precise lubrication, and accurate control of lubricating oil volume. This improves work efficiency while reducing lubricating oil waste and lowering operating costs.

[0059] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
