[0002] Crawler bulldozers are one of the commonly used construction machinery in coal mine earthwork and terrain transformation. However, when bulldozers operate on slopes with large lateral or longitudinal slopes, there are great safety risks. In this case, due to the instability of the ground and the change of the bulldozer's center of gravity, the bulldozer is prone to rollover or slip, which will not only cause damage to the machine itself, but also pose a threat to the operator and the surrounding environment. In the existing technology, there is no effective solution to ensure the stable operation of bulldozers on these complex slopes. . Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 The present invention is a schematic flow chart of a crawler bulldozer lowering operation method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] The crawler bulldozer lowering operation method according to the embodiment of the present invention comprises the following steps:

[0024] S1. Conducting a topographic survey on the working slope. It is understood that conducting a topographic survey on the working slope includes surveying the stability of the slope, soil type and underground conditions.

[0025] It should be noted that topographic survey is to understand the geological structure, soil type, slope, ground moisture, etc. of the operation area, and to evaluate the stability of the slope and the feasibility of the operation. During the topographic survey, surveying equipment (such as laser rangefinders, GPS equipment) and geological survey tools can be used to conduct on-site surveys, collect data and analyze them.

[0026] In some embodiments, the crawler bulldozer lowering operation method of the embodiment of the present invention further includes: clearing obstacles on the slope surface and filling cracks or settlements on the slope surface. It is understandable that obstacles on the slope surface, such as large rocks, branches, etc., are cleared to ensure the smooth operation path. If the slope surface is too steep or unstable, appropriate repairs may be required, such as digging drainage ditches, reinforcing the slope surface, etc.

[0027] S2. Plan the operation route of the crawler bulldozer based on the results of the terrain survey, that is, divide the route in the direction from the bottom of the slope to the top of the slope into multiple temporary platforms, and the transverse slope between two adjacent temporary platforms is less than or equal to 15°, and the longitudinal slope between two adjacent temporary platforms is less than or equal to 30°.

[0028] It is understandable that according to the results of the terrain survey, a safe operation path is planned to reduce the risk during the operation. Multiple temporary platforms are divided on the slope surface to ensure that the slope between each platform does not exceed the safety limit (below 15° horizontal slope and 30° longitudinal slope). This can provide a stable working area and reduce the risk of bulldozer sliding and overturning.

[0029] That is to say, according to the results of terrain survey, if the working slope exceeds the safety limit, that is, the slope has a transverse slope of more than 15° and a longitudinal slope greater than 30°, multiple temporary platforms can be set up as the slope rises, and new travel slopes can be opened between adjacent temporary platforms, and the transverse slope between two adjacent temporary platforms can be ensured to be less than or equal to 15°, and the longitudinal slope between two adjacent temporary platforms can be ensured to be less than or equal to 30°. In this way, the working slope of the entire slope can be ensured to be within a safe inclination range, thereby reducing the risk of bulldozers operating on the slope and improving operational safety.

[0030] Optionally, in step S2, the distance from the bottom of the slope to the lowest temporary platform, the distance between two adjacent temporary platforms, and the distance from the top of the slope to the highest temporary platform are all equal.

[0031] It is understandable that the temporary platforms are evenly divided according to the actual length of the slope and the operation requirements, and the distance between each interval is kept consistent. In other words, by keeping the distance from the bottom of the slope to the lowest temporary platform, between adjacent temporary platforms, and between the top of the slope to the highest temporary platform equal, it can ensure that the bulldozer has similar working conditions when operating on each temporary platform, thereby improving the uniformity and efficiency of the operation.

[0032] Preferably, in the direction from the bottom of the slope to the top of the slope, the ratio of the distance from the bottom of the slope to the lowest temporary platform to the distance from the bottom of the slope to the top of the slope is greater than or equal to 0.2 and less than or equal to 0.5.

[0033] It is understandable that the distance from the bottom of the slope to the lowest temporary platform is calculated according to the actual length of the slope and the operation requirements, ensuring that the ratio of the distance from the bottom of the slope to the top of the slope is between 0.2 and 0.5. This ensures that there is enough space for the operation and avoids the increase of operation risks caused by too short a distance.

[0034] Therefore, by setting the ratio of the distance between the bottom of the slope to the lowest temporary platform and the distance between the bottom of the slope to the top of the slope, the difficulty and risk of the operation can be better controlled.

[0035] Optionally, a plurality of temporary suspension platforms are arranged in a zigzag shape. That is to say, the temporary suspension platforms are alternately arranged on the slope surface to form a zigzag shape, which can effectively utilize the terrain, reduce damage to the slope surface, and increase the operating area and stability of the bulldozer at the same time.

[0036] In other words, by arranging multiple temporary platforms in a zigzag shape, more working space can be provided on complex terrain and the risk of sliding when the bulldozer is working on the slope can be reduced.

[0037] S3. Adjusting the center of gravity of the crawler bulldozer according to the planned operation route. Optionally, adjusting the center of gravity of the crawler bulldozer includes: adjusting the center of gravity by adjusting the distribution of counterweights.

[0038] That is to say, by adjusting the distribution of the counterweights on the bulldozer, the center of gravity of the bulldozer is changed to make it more suitable for the slope. For example, if the bulldozer is working on a downward slope, the counterweights can be moved to the rear of the bulldozer to lower the center of gravity and increase stability, ensuring the stability of the bulldozer when working on the slope and preventing it from rolling over or losing control.

[0039] S4. Check and ensure that safety protection measures are in place.

[0040] In some embodiments, in step S4, the safety measures adopted include: resetting the driver's seat belt, arranging the anti-skid plate, and resetting the emergency stop button.

[0041] It is understandable that before the operator starts the crawler bulldozer, check and ensure that the driver's seat belt is properly worn, the anti-skid plate is installed on the bulldozer, and the emergency stop button is easily accessible and in the reset state. These measures help to take quick action in an emergency, prevent accidents, and ensure the safety of operators and machinery during operation.

[0042] S5. Install a dynamic monitoring system on the crawler bulldozer to monitor the stability of the crawler bulldozer on the slope in real time.

[0043] In some embodiments, in step S5, the monitoring system includes an inclinometer and a velocity sensor.

[0044] It is understandable that inclinometers and speed sensors are installed to monitor the inclination angle and speed of the bulldozer in real time. These sensors can transmit data to the monitoring system, which can analyze the data and issue an alarm when necessary, monitor the stability of the bulldozer on the slope in real time, and ensure the safety of the operation.

[0045] In addition, the inclinometer and speed sensor can provide the real-time tilt angle and speed data of the bulldozer on the slope, helping the operator to understand the current status of the bulldozer and take measures to prevent loss of control. Of course, according to the actual construction conditions, other detection equipment, such as acceleration sensors, can also be used to more comprehensively monitor the actual operation of the crawler bulldozer.

[0046] In some embodiments, the monitoring system further includes an alarm component, which is connected to the monitoring system so that when the monitoring system detects that the real-time data exceeds a preset safety value, a start message is sent to the alarm component, and the alarm component sends an alarm signal.

[0047] That is to say, if the monitoring system detects that the tilt angle or speed of the bulldozer exceeds the preset safety value, the warning device will send out a warning signal, such as flashing lights, beeps, etc., to remind the operator to take emergency measures.

[0048] In addition, when the crawler bulldozer is operating, it should be noted that the crawler bulldozer must operate perpendicular to the top line of the slope, and it is strictly forbidden to operate parallel to the top line of the slope; choose a safe and appropriate shovel lowering position according to the stability of the descending step, and the distance from the top line of the slope should be greater than 5 meters; when reverse sliding occurs on the slope, the load must be unloaded immediately and the bulldozer head must be turned downhill to prevent rollover; when pushing materials, the distance between the shovel blade and the top line of the slope must be greater than 2 meters; after the bulldozer has pushed the material into place, brake first, then shift into reverse gear, and then lift the shovel blade; when pushing materials, the material must not exceed the guardrail on the top of the shovel blade.

[0049] The crawler bulldozer lowering operation method of the embodiment of the present invention also includes the following steps: after the lowering process is completed, the construction personnel exit the working position under the command of the commander, and it should be noted that the commander's command is clear and accurate, and the parking position of the operating equipment is clear.

[0050] The crawler bulldozer lowering operation method of the embodiment of the present invention can plan the operation route and the temporary platform together, so as to make the operation of the crawler bulldozer more orderly and efficient, reduce unnecessary repeated operations, and improve the operation efficiency. In addition, the operator can operate according to the pre-planned operation route and temporary platform, which reduces the difficulty and complexity of the operation.

[0051] Therefore, the present invention has the following advantages:

[0052] Improved safety: Through detailed terrain surveys and operation route planning, the risks of bulldozers operating on slopes are reduced and operation safety is improved.

[0053] Improved operating efficiency: Reasonable planning of operating routes and temporary platforms can make bulldozing operations more orderly and efficient, reducing unnecessary repetitive operations.

[0054] Stability assurance: Adjusting the center of gravity of the bulldozer and installing a dynamic monitoring system can monitor the stability of the bulldozer in real time and ensure the safe operation of the bulldozer when operating on a slope.

[0055] Strong adaptability: This method is suitable for operations on terrains with different slopes. It has strong adaptability and can maintain the stability and operating efficiency of the bulldozer under various terrain conditions.

[0056] Reduced operational difficulty: Operators can operate according to pre-planned operating routes and temporary platforms, reducing the difficulty and complexity of operations.

[0057] Reduce mechanical wear: By reducing the unstable operation of the bulldozer on the slope, the wear of the machinery can be reduced and the service life of the equipment can be extended.
