Description

Technical Field

[0001] This utility model relates to an injection device, specifically an injection device with fuel shortage feedback under wheel axial pressure. Background Technology

[0002] Friction occurs between the I-beam rails and the all-metal wheels used in conjunction with them. To reduce wear, a lubrication system sprays oil onto the contact surfaces to achieve a lubricating effect. The lubrication system usually sprays oil at regular intervals and in measured quantities. However, in the curved sections of the rails, the presence of centrifugal force causes greater friction between the wheels and the rails, resulting in more lubricating oil consumption. If there is a lack of oil at the curve, the wear will be accelerated under the influence of centrifugal force. Therefore, it is necessary to set up oil shortage feedback and oil replenishment spray at the curves of the rails. Utility Model Content

[0003] To address the shortcomings of the prior art, this invention provides an oil injection device with feedback on insufficient oil under wheel axial pressure. This invention uses a pre-monitoring and judgment method, that is, it uses temperature changes to determine that the lubricating oil in the curve is about to run out, and replenishes oil before entering the curve again, preventing wear on the wheels and tracks due to delayed information.

[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: an injection device with oil shortage feedback under wheel axial pressure, comprising a track, a frame, and a wheel. The frame is provided with an outer support plate and an inner support plate, both of which are connected to the wheel's axle. A non-contact temperature sensor is installed on the inner support plate, facing the inner side of the wheel flange to monitor the flange temperature. An injection mounting block is provided on the outer support plate, and an injection pipe is configured on the injection mounting block, with the nozzle of the injection pipe facing the outer side of the track.

[0005] The inner support plate has a through hole, and a circular ring is installed in the through hole. The non-contact temperature sensor is assembled in the circular ring, and the detection surface of the non-contact temperature sensor is flush with the end face of the circular ring.

[0006] The inner support plate is fixed with a mounting plate, and the non-contact temperature sensor is fastened to the mounting plate with a fixed bracket.

[0007] The oil spray mounting block is fixed with a mounting block, which is fastened to the outer support plate. The oil spray mounting block is in an inclined state, so that the nozzle sprays downward onto the upper middle part of the outer side of the track.

[0008] The fuel injection mounting block includes a fixed half block and a movable half block. The fixed half block is fixed to the mounting block, and the movable half block is snapped into the fixed half block and fastened with bolts. Both the fixed half block and the movable half block have storage cavities inside, and the two storage cavities are connected. The nozzle is fixed on the movable half block, and the fuel injection pipe passes through the fixed half block, enters the storage cavity, then passes through the movable half block, and connects to the nozzle.

[0009] The fixed half-block includes a first base, which is integrally formed with a first baffle and a first main body. The movable half-block includes a second base, which is integrally formed with a second baffle and a second main body. The first baffle, the second main body, the first main body, and the second baffle are stacked sequentially to achieve interlocking.

[0010] The first baffle, the second body, the first body, and the second baffle are all provided with a first elongated hole and a second elongated hole, and are fitted with bolts; the first elongated hole and the second elongated hole avoid the location of the storage cavity.

[0011] In summary, this utility model achieves the following technical effects:

[0012] This invention utilizes a non-contact temperature sensor to detect the wheel flange temperature during the entry and exit of the curve. If lubrication is about to run out, slight friction will occur between the wheel flange and the outer side of the guide rail, generating heat. As the wheel continues to rotate, the temperature of the entire wheel will rise to a certain extent, especially the temperature of the wheel flange surface. A temperature value is set, and when the wheel flange temperature reaches this value, it indicates that the lubrication level is low and lubrication needs to be replenished. The non-contact temperature sensor sends a signal to the PLC. If the PLC determines that the real-time temperature exceeds the value, it means that the curve section is about to run out of lubrication and lubrication needs to be replenished later. After the trolley completes one revolution, the proximity switch component at the entrance of the curve section detects that the wheel has re-entered the curve section, and the PLC controls the nozzles of the lubrication system to spray oil onto the outer side of the guide rail. This invention has nozzles installed on the front side of the trolley wheels to spray oil before the wheels, and a proximity switch component is installed at the exit of the curve to detect whether the wheel has left the curve. Once the wheel leaves the curve, oil spraying stops to avoid spraying oil onto the straight section of the track, resulting in excessive oil on the straight section. Attached Figure Description

[0025] Example:

[0026] Figure 1 This application describes a fuel injection device with fuel shortage feedback under wheel axial pressure. Axial pressure refers to the direction of the wheel axle. When traveling on a curved section of the track, centrifugal force is applied, resulting in axial pressure on the wheel axle. This application designs a fuel injection device with fuel shortage feedback under this axial pressure. Figure 2 This is a schematic diagram of the application on track 1, including track 1, frame 3, and wheels 2. The frame 3 is provided with an outer support plate 301 and an inner support plate 302. Both the outer support plate 301 and the inner support plate 302 are connected to the axle of the wheels 2. The inner support plate 302 is equipped with a non-contact temperature sensor 4, which faces the inner side of the wheel flange of the wheels 2 to monitor the flange temperature. The outer support plate 301 is provided with an oil injection mounting block 5, which is equipped with an oil injection pipe 502. The nozzle 503 of the oil injection pipe 502 faces the outer side of the track 1.

[0027] When the track is low on oil, friction occurs between the wheels and the track, causing the temperature to rise. When the track is about to run out of oil or the oil level is very low and needs to be replenished quickly, there will also be some slight heat between the track and the wheels. This invention uses the temperature rise before the track runs out of oil to determine the timing of oil replenishment.

[0028] This invention utilizes a non-contact temperature sensor to detect the wheel flange temperature during the entry and exit of the curve. If lubrication is about to run out, slight friction will occur between the wheel flange and the outer side of the guide rail, generating heat. As the wheel continues to rotate, the temperature of the entire wheel will rise to a certain extent, especially the flange surface. A temperature value is set, and when the flange temperature reaches this value, it indicates that the lubrication level is low and lubrication needs to be replenished. The non-contact temperature sensor sends a signal to the PLC. If the PLC determines that the real-time temperature exceeds the value, it means that the curve section is about to run out of lubrication and lubrication needs to be replenished later. After the trolley completes one revolution, the proximity switch component at the entrance of the curve section detects that the wheel has re-entered the curve section, and the PLC controls the lubrication system nozzles to spray oil onto the outer side of the guide rail. This invention has nozzles installed on the front side of the trolley wheels to spray oil before the wheels, and a proximity switch component is installed at the exit of the curve to detect whether the wheel has left the curve. Once the wheel leaves the curve, oil spraying stops to avoid spraying oil onto the straight section of the track, resulting in excessive oil on the straight section.

[0029] This invention is a pre-monitoring and judgment method, that is, it uses temperature changes to determine that the lubricating oil in the curve is about to run out, and adds oil before entering the curve again, so as to prevent wear of the wheels and tracks due to delayed information.

[0030] The inner support plate 302 has a through hole, through which a circular ring post 402 is installed. The non-contact temperature sensor 4 is assembled in the circular ring post 402, and the detection surface 401 of the non-contact temperature sensor 4 is flush with the end face of the circular ring post 402. The circular ring post 402 in this invention can protect the sensor.

[0031] The inner support plate 302 is fixed with the mounting plate 303, and the non-contact temperature sensor 4 is fastened to the mounting plate 303 by the fixing bracket 403.

[0032] The detection surface 401 of the non-contact temperature sensor 4 faces the wheel flange, facilitating temperature monitoring. Due to the small distance between the sensor and the flange, temperature measurement is highly accurate. Proximity switch assemblies are installed at the entrance and exit of the track curve to monitor whether the non-contact temperature sensor 4 enters or leaves the curve. Measurement of the flange temperature begins while the sensor is within the curve; it does not measure when leaving or not entering the curve. The connection lines of the proximity switch assemblies, PLC, and non-contact temperature sensor are existing technology and will not be described further.

[0033] like Figure 1As shown, the oil spray mounting block 5 is fixed with mounting block 501, and mounting block 501 is fastened to the outer support plate 301. The oil spray mounting block 5 is in an inclined state, so that the nozzle 503 sprays downward onto the upper middle part of the outer side of the track 1. The oil flows downward by its own weight, thereby covering the entire outer side of the track.

[0034] Figure 3 This is a schematic diagram of the paint spray mounting block. Figure 4 yes Figure 3 A cross-sectional schematic diagram. Figure 5 yes Figure 3 The schematic diagram shows the split structure of the fuel injection mounting block 5, which includes a fixed half block 504 and a movable half block 505. The fixed half block 504 is fixed to the mounting block 501, and the movable half block 505 is snapped into the fixed half block 504 and fastened with bolts. Both the fixed half block 504 and the movable half block 505 are provided with storage cavities 506, and the two storage cavities 506 are connected. The nozzle 503 is fixed to the movable half block 505. The fuel injection pipe 502 passes through the fixed half block 504, enters the storage cavity 506, then passes through the movable half block 505, and connects to the nozzle 503.

[0035] This invention features a split-type fuel injection mounting block with a snap-fit ​​connection, allowing the entire length to be extended or shortened as needed for efficient fuel injection. The storage chamber stores the fuel injection pipe, which is coiled and stored within the chamber for a specific length. When the two halves are extended, they match in length. The fuel injection pipe 502 is made of a metal casing, and its position changes accordingly as the two halves are extended or shortened. This invention addresses the shortcomings of insufficiently long or excessively short nozzles, allowing for precise nozzle positioning and improved fuel injection.

[0036] The fixed half-block 504 is set with the first hole 5040, the movable half-block 505 is set with the second hole 5050, one end of the fuel injection pipe 502 is fixed in the first hole 5040 and then extends into the storage cavity, and rotates several times in the storage cavity before being fixed in the second hole 5050.

[0037] like Figure 5 As shown, the fixed half-block 504 includes a first base, which is integrally formed with a first baffle 5041 and a first main body 5042. The movable half-block 505 includes a second base, which is integrally formed with a second baffle 5051 and a second main body 5052. The first baffle 5041, the second main body 5052, the first main body 5042, and the second baffle 5051 are stacked sequentially to achieve a snap-fit ​​connection.

[0038] Figure 6This is a schematic diagram of the elongated oil injection mounting block. The first baffle 5041 and the second baffle 5051 of this utility model serve to shield the internal storage cavity after the two halves are elongated, preventing the oil pipe from being exposed to the outside.

[0039] The first baffle 5041, the second main body 5052, and the second baffle 5051 are all provided with a first elongated hole 507 and a second elongated hole 508, and are fitted with bolts; the first elongated hole 507 and the second elongated hole 508 are positioned away from the storage cavity 506. When pulled to the appropriate position, the bolts are used for fastening. Since the fixing is done with elongated holes, it can accommodate the two half-pieces being extended.

[0040] Wheel 2 is made of steel, such as CL60 steel. The friction between the wheel and the I-beam generates heat, and the temperature is easily monitored by the non-contact temperature sensor 4.

[0041] Working principle:

[0042] A temperature value is preset, and when the monitored wheel flange temperature exceeds this value, it indicates that the rail is about to run out of oil;

[0043] A proximity switch assembly is installed at the entrance of the curve section of track 1. When the front wheel of the trolley enters the curve section, friction occurs between the wheel flange and the track. As the wheel continues to rotate, the friction generates heat, causing the entire surface of the flange to heat up. The non-contact temperature sensor 4 continuously monitors the flange temperature in this curve section of the track and sends the signal to the PLC in real time. When the PLC determines that the real-time temperature exceeds the specified temperature value, it indicates that the curve section is about to run out of oil and needs to be replenished later. After the trolley has completed one revolution, when the proximity switch assembly at the entrance of the curve section detects that the wheel has re-entered the curve section, the PLC controls the lubrication system to spray oil onto the outer surface of the track through the oil spray mounting block and nozzle 503.

[0044] A proximity switch assembly is installed at the exit of the track curve to monitor whether the wheel leaves the curve. Once the wheel leaves the curve, the PLC controls the lubrication system to stop spraying oil to prevent oil spraying onto the straight section of track where lubrication is sufficient.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
