Description

Technical Field

[0001] This invention relates to the field of oil quantity detection technology, and in particular to a method and apparatus for monitoring oil quantity to detect load. Background Technology

[0002] Taking diesel consumption as an example, assuming constant factors such as elevation, driving skills, and vehicle condition, the key factors affecting diesel consumption of dump trucks are the load of the material being hauled and the truck's own weight. A portion of the fuel consumed is used to overcome the truck's own weight, and another portion is used to overcome the load of the cargo. Meanwhile, the haul distance is a directly related metric to truck fuel consumption; its accuracy directly determines the accuracy of the fuel consumption parameter. Using a truck dispatching system, the haul distance of each truck is measured, and the product of haul distance and load is accumulated. Finally, the accumulated fuel consumption of the truck is divided by the accumulated value of the product to obtain the true ton-kilometer fuel consumption parameter for each truck. For open-pit coal mine stripping transport vehicles, the load capacity is converted using a fixed formula, with the unit being tons.

[0003] When vehicles are weighed, they are prone to accumulating mud and other debris due to their operation in open-pit coal mines. This mud and debris can affect the weighing results, necessitating the cleaning of the weighing equipment before use. Summary of the Invention

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1-6 This is the first embodiment of the present invention, which provides a method for monitoring oil quantity to detect load, comprising the following steps:

[0035] Step S1: When the vehicle enters the device, the vehicle first enters the uphill section, the device lifts the lever, and the device is cleaned.

[0036] Step S2: When the vehicle enters the device for testing, the device closes its lever and weighs the vehicle.

[0037] Step S3: When the vehicle exits the device, it enters the downhill section, and the device lifts the lever and is cleaned and reset.

[0038] In steps S1 and S3, the vehicle can enter the device from either side of the ramp (uphill section) and exit from the other side (downhill section). In step S2, the vehicle moves into the device, stops, and remains stable before the weighing mechanism is activated to weigh the vehicle.

[0039] It should be noted that the vehicle enters from either side of the ramp, ascends the slope, and the barrier is raised to create space for the vehicle to enter the device. Simultaneously, the upper surface of the device is cleaned. After the vehicle enters the device, the barriers on both sides close, and the vehicle remains stationary while being weighed. After weighing, the vehicle exits via the other side of the ramp, descending the slope. The barrier is also raised again to create space for the vehicle to leave. By monitoring the empty vehicle status before and after transport and subtracting the results from the two measurements, the amount of fuel reduced during the trip can be determined, thus enabling fuel level monitoring.

[0040] Example 2

[0041] Reference Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a fuel level monitoring device for detecting load, including a fuel level monitoring method for detecting load, and a lane component 100 comprising ramp sections 101 at both ends and a platform section 102 in the middle. A pressure member 103 is provided on the ramp section 101, and a weighing sensor 104 is provided at the bottom of the platform section 102. Access control components 200 are installed on both sides of the lane component 100, and include pillars 2 on both sides of the ramp section 101. 01 and a rod 202 rotatably mounted on the column 201, the pressing member 103 is connected to the rod 202 via the transmission member 203 to drive the rod 202 to lift the pole, and the cleaning member 300 is installed on the upper surface of the lane member 100, which includes two cleaning scrapers 301 located on the upper surface of the platform section 102, and a moving member 302 is provided at the same end of the two cleaning scrapers 301. The moving member 302 is connected to the rod 202 via a rope 303 to drive the moving member 302 to move to both sides when the pole is lifted.

[0042] In this embodiment, the vehicle first moves uphill through either side of the ramp section 101, squeezing the pressing member 103 on the ramp section 101. The pressing member 103 drives the rod 202 to rotate on the column 201 through the transmission member 203, raising the rod to make room for the vehicle to enter the platform section 102 from the ramp section 101. At the same time, when the rod 202 is raised, it drives the moving member 302 to move to both sides through the rope 303, allowing the cleaning scraper 301 to clean from the middle to both sides of the platform section 102. When the vehicle enters the platform section 102, it is weighed by the weighing sensor 104 located below the platform section 102. After the vehicle is weighed, the vehicle leaves from the other side of the ramp section 101.

[0043] In summary, when a vehicle enters the device, the cleaning component 300 moves from the center to both sides to clean the surface of the device, ensuring the surface is clean and reducing weighing errors. At the same time, when it is located on both sides of the device, it acts as a guardrail to block and guide the vehicle on both sides. The pole 202 blocks the device before the vehicle enters, after the vehicle leaves, and when the vehicle is being weighed, preventing other vehicles from entering.

[0044] Example 3

[0045] Reference Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an oil level monitoring device for detecting load. It includes two symmetrical grooves 101a on the surface of a ramp section 101. Each groove 101a has a pressing member 103 installed in it. The pressing member 103 includes a pressure plate 103a and a first scissor member 103b installed on the bottom surface of the pressure plate 103a. Limiting grooves 103c are provided on the lower surface of the pressure plate 103a and the inner bottom surface of the groove 101a. Each sliding foot 103d hinged at the upper and lower ends of the first scissor member 103b slides in the limiting groove 103c. A first spring 103e is provided between the two sliding feet 103d at the lower end.

[0046] Furthermore, the columns 201 are located at the midpoint on both sides of the ramp section 101, and each column 201 has a notch 201a at its upper end. One end of the rod 202 is rotatably installed in one of the notches 201a through a pivot 202a.

[0047] Furthermore, a cavity 201b is opened inside the column 201 on which the rod body 202 is rotatably installed. The transmission component 203 includes a toothed plate 203a that slides along the limiting groove 103c. One end of the toothed plate 203a is fixedly connected to the sliding foot 103d. A gear 203b is meshed at the upper end of the toothed plate 203a. A first bevel gear 203c is fixedly connected to the gear 203b through a rotating rod. A second bevel gear 203d is meshed with the first bevel gear 203c. A first pulley 203e is coaxially arranged on the second bevel gear 203d. A second pulley 203f is also arranged on the rotating shaft 202a. A belt 203g is sleeved between the first pulley 203e and the second pulley 203f.

[0048] Specifically, the upper end of the first scissor lift 103b is hinged with two sliding feet 103d, and the lower end is also hinged with two sliding feet 103d. The two ends of the first spring 103e are connected to the two sliding feet 103d at the lower end, which are used to close the gap between the two sliding feet 103d, and serve as the power for the reverse rotation of the rod 202 and the reverse movement and reset of the pressure plate 103a.

[0049] When the vehicle is ready for inspection, it moves to ramp section 101 to prepare for uphill operation. First, the pressure plate 103a on ramp section 101 is pressed down. The downward pressure of the pressure plate 103a longitudinally compresses the first scissor lift member 103b, increasing the lateral spacing of the first scissor lift member 103b. This increases the distance between the two sliding feet 103d at the lower end of the first scissor lift member 103b. One of the sliding feet 103d drives the toothed plate 203a fixed to it within the limiting groove 103c. The movement of the toothed plate 203a causes the gear 203b located above it to rotate. The rotation of gear 203b drives the first bevel gear 203c to rotate via a rotating rod. The first bevel gear 203c drives the second bevel gear 203d, which meshes with it, to rotate. The second bevel gear 203d drives the first pulley 203e, which is coaxially arranged, to rotate. The first pulley 203e drives the second pulley 203f to rotate via belt 203g. The second pulley 203f drives the rod 202 to rotate via rotating shaft 202a, lifting the rod 202. The vehicle can then enter the platform section 102 from the ramp section 101 for subsequent weighing.

[0050] When all vehicles have moved to platform section 102, they disengage from pressure plate 103a. The first scissor lift 103b deforms and recovers under the action of the first spring 103e, that is, the longitudinal spacing of the first scissor lift 103b increases and the lateral spacing decreases. Thus, the sliding foot 103d drives the toothed plate 203a to move in the opposite direction in the limiting groove 103c. The toothed plate 203a drives the gear 203b to reverse. The gear 203b drives the first bevel gear 203c and the second bevel gear 203d to reverse. The second bevel gear 203d drives the first pulley 203e to reverse. The first pulley 203e drives the second pulley 203f to rotate through belt 203g. The second pulley 203f reverses through shaft 202a and rod 202. The rod 202 reverses and recovers, intercepting and sealing the device to prevent other vehicles from entering.

[0051] After the vehicle inspection is completed, the vehicle moves from the platform section 102 to the ramp section 101. The pressure plate 103a on the ramp section 101 is pressed down first. Similarly, the pressure plate 103a deforms the first scissor lift 103b. The first scissor lift 103b drives the gear 203b to rotate through the toothed plate 203a. The gear 203b drives the second pulley 203f to rotate through the first bevel gear 203c, the second bevel gear 203d, the first pulley 203e, and the belt 203g. The rotation of the second pulley 203f causes the rod 202 to be lifted again, and the vehicle can enter the ramp section 101 from the platform section 102 and finally move out.

[0052] Example 4

[0053] Reference Figures 2-6 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an oil level monitoring device for detecting load. The moving part 302 includes a slide groove 302a located at the bottom of the platform section 102. Two slide blocks 302b are symmetrically slidably arranged inside the slide groove 302a, and a second spring 302c is arranged between the two slide blocks 302b. The two slide blocks 302b are connected by a second scissor fork 302d. A spring box 302e is arranged inside one of the slide blocks 302b. One end of the rope 303 is fixed inside the spring box 302e, and the other end is fixed to the free end of the rod 202.

[0054] It should be noted that the rope 303 in the spring box 302e can be stretched when pulled once, but cannot be stretched when pulled again, and the rope 303 is contracted. This ensures that when there is no vehicle on the platform section 102, the rope 303 does not extend but shortens, so that the rod 202 stands up and drives the slide 302b to move. When there is a vehicle on the platform section 102, the rope 303 extends, so that the rod 202 stands up without driving the slide 302b to move.

[0055] The second scissor lift 302d has a slot, and the back of the slide block 302b has a slider that can move along the slot. In this way, the left and right slide blocks 302b are driven by the second scissor lift 302d to ensure that the left and right slide blocks 302b move synchronously.

[0056] In use, when the vehicle enters the ramp section 101, the pressing member 103 is pressed down. The pressing member 103 drives the rod 202 to rotate on the column 201 through the transmission member 203, realizing the rotation and lifting of the rod 202. When the rod 202 is lifted, its free end drives the spring box 302e to move through the rope 303. The spring box 302e is installed on the slide 302b, so that the slide 302b moves from the middle to one side along the slide groove 302a. When the slide 302b moves, it drives the other slide 302b to move to the other side through the second scissor fork member 302d, realizing the synchronous expansion of the two slides 302b. Each slide 302b is provided with a cleaning scraper 301 at its upper end. The cleaning scraper 301 moves from the middle to both sides to clean the upper surface of the platform section 102.

[0057] When the vehicle leaves the platform section 102 and the ramp section 101, the two slide blocks 302b move closer to each other under the action of the internal second spring 302c, and the cleaning scraper 301 located above the slide block 302b also moves to the middle and resets to the middle of the platform section 102.

[0058] Among them, triangular plates 102a are provided on both sides of the lower surface of the platform section 102, and a second protrusion 302f is provided on the outer side of the slide block 302b. The triangular plates 102a are used to hold the second protrusion 302f.

[0059] It should be noted that when the vehicle is on platform section 102, the platform section 102 is pressed down, causing the triangular plate 102a located on its lower surface to also descend. The triangular plate 102a engages with the second protrusion 302f located on its outer side to limit its movement and prevent it from returning to its original position, thus ensuring that the cleaning scraper 301 does not operate when there is a vehicle above the platform section 102.
