Description

Technical Field

[0001] This invention relates to the field of throttle control device technology, and particularly to a throttle control device for an underground internal combustion loader. Background Technology

[0002] In underground mining and tunnel construction, internal combustion loaders are important transportation equipment, and their performance stability and operational safety are of paramount importance. The throttle control device, as a key component of the loader control system, directly affects the equipment's handling performance and the driver's operating experience.

[0003] Traditional underground internal combustion loader throttle control devices mostly use simple mechanical structures, using elastic elements such as springs to achieve the buffering and return functions of the throttle. However, when the driver presses the throttle, he often cannot accurately perceive the degree of throttle opening, which can easily lead to operational errors. Since it only relies on elastic elements such as springs for buffering, when the driver applies too much force, the throttle may open too much in an instant, causing the equipment to accelerate too quickly. This not only affects the stability of the equipment, but may also pose a potential threat to the driver and the surrounding environment. Summary of the Invention

[0004] The purpose of this invention is to provide a throttle control device for an underground internal combustion loader, in order to solve the problem mentioned in the background art that when the driver applies too much force, the throttle may be opened too much at once, causing the equipment to accelerate too quickly and affecting the stability of the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The buffer plate and its through holes inside the transmission cylinder of the present invention, as well as the design of controlling the water flow into the water storage box by moving the second circular plate, provide a stable and efficient buffering effect for the throttle control device. At the same time, the squeezing force of the water flow can be more evenly dispersed and absorb the impact force, thereby achieving more stable throttle control.

[0016] 2. By using a combination of a first damping spring, a second damping spring, and a third damping spring, this invention achieves phased pressure feedback during the pressing of the accelerator pedal. This design allows the driver to clearly feel the changes in resistance at different stages when pressing the accelerator, thereby more accurately controlling the degree of accelerator opening and avoiding excessive throttle due to excessive force, significantly improving the safety and stability of operation.

[0017] 3. By installing a rhomboid rotating frame on the surface of the through hole, this invention can automatically adjust the size of the through hole according to the movement of the second circular plate, thereby realizing intelligent adjustment of the water flow speed.

[0018] 4. The rhomboid rotating frame of the present invention can automatically move away when the second circular plate is removed, making the through hole larger, thereby accelerating the reset speed of the water flow.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-9 The present invention provides a throttle control device for an underground internal combustion loader, including a base 1. The top of the base 1 is provided with a transmission mechanism 3 having a transmission cylinder 32. The transmission cylinder 32 is rotatably mounted on the top of the base 1. The transmission cylinder 32 is provided with a first transmission component 33, a second transmission component 34 and a third transmission component 35 for testing pressure feedback.

[0023] Among them, the first transmission component 33, the second transmission component 34 and the third transmission component 35 can provide stepped support for the foot pedal 2 when it is pressed, thereby forming kinetic energy transmission and reducing pressure damage. Thus, through the combination of transmission components and buffer mechanism 5, precise control and stable buffering of throttle operation are achieved.

[0024] In the technical solution of this application embodiment, a water storage box 58 is connected to the bottom end of the transmission cylinder 32. A buffer mechanism 5 with a first buffer plate 51 and a second buffer plate 52 is provided between the transmission cylinder 32 and the water storage box 58. The surfaces of the first buffer plate 51 and the second buffer plate 52 are connected to a through hole for drainage. A gap assembly 56 with a sealing component 565 is provided between the first buffer plate 51 and the second buffer plate 52. The sealing component 565 is provided on the surface of the through hole. The sealing component 565 includes a groove 5651 opened on the surface of the second buffer plate 52 near the surface of the first buffer plate 51. A rhomboid rotating frame 5652 is slidably installed inside the groove 5651. A baffle 5653 for controlling the water flow rate is installed on the surface of the rhomboid rotating frame 5652 near the through hole.

[0025] The first buffer plate 51 and the second buffer plate 52 can block the water source inside the water storage box 58 and allow water to flow through the through hole. This allows the second circular plate 343 to be buffered by the water flow when it moves. In addition, the compressed air pushes the rhomboid rotating frame 5652 to deform, so that the rhomboid rotating frame 5652 pushes the partition 5653 to combine and reduce the opening size of the through hole, thereby increasing the pressure of the second circular plate 343 and improving the height buffering effect of the foot pedal 2.

[0026] In some embodiments, a support rod 561 is installed on one side of the second transmission member 34, and a telescopic member 564 for driving the deformation of the closed member 565 is installed between the first buffer plate 51 and the second buffer plate 52. One end of the telescopic member 564 is fixedly connected to one end of the closed member 565, and a bronchus 563 is connected to the free end of the telescopic member 564. A long tube 562 is connected to the free end of the bronchus 563. A plug for pressurizing the air pressure inside the telescopic member 564 is installed at one end of the support rod 561 located inside the long tube 562.

[0027] When pressure is applied inside the transmission cylinder 32, the second circular plate 343 moves under pressure, which in turn moves the sealing ring 341. The sealing ring 341 then moves the support rod 561, which in turn moves the plug at one end inside the long tube 562. This pressurizes the air inside the long tube 562 and introduces it into the telescopic member 564 through the branch pipe 563. When the telescopic member 564 is affected by air pressure, one end of the telescopic member 564 pushes, causing the rhomboid rotating frame 5652 to deform and move the partition plate 5653 to the surface of the through hole. This achieves the function of dynamically adjusting the size of the through hole through changes in air pressure, improving the flexibility and adaptability of the buffering effect.

[0028] In some embodiments, a ring-shaped telescopic mechanism composed of multiple rhomboid rotating frames 5652 and a ring-shaped plate composed of multiple partitions 5653 for closing through holes.

[0029] Among them, multiple baffles 5653 form a ring, thereby comprehensively reducing the gaps in the through holes, thus providing a stable sealing and regulating mechanism for the water flow holes, ensuring the continuity and stability of water flow buffering.

[0030] In some embodiments, the first buffer plate 51 and the second buffer plate 52 are combined and installed at the tail of the transmission cylinder 32, and a sealing gasket is provided between the first buffer plate 51 and the second buffer plate 52.

[0031] The combination of the first buffer plate 51 and the second buffer plate 52 can enclose and protect the rhomboid rotating frame 5652, thereby preventing the partition plate 5653 from being impacted by the water flow, causing the partition plate 5653 to deform and shift, and allowing the through hole to stably change the gap, thereby improving the sealing between the buffer mechanisms 5 and preventing water leakage and air pressure loss.

[0032] In some embodiments, a tapered tube 53 is installed inside the through hole, and drain pipes 54 are provided at both ends of the tapered tube 53. A cavity 57 is provided in the middle of the tapered tube 53, and a plurality of carbon rods 55 are rotatably installed inside the cavity 57.

[0033] The multiple cone tubes 53 enable stable water pressure output and reduce blockage. The carbon rod 55 continuously adsorbs impurities and odors from the water, achieving effective regulation and purification of the water flow and improving the quality and stability of the buffering effect. The design of the cone tubes 53 and the drain pipe 54 makes the water flow smoother and reduces resistance.

[0034] In some embodiments, the first transmission member 33 is disposed inside the transmission cylinder 32. The first transmission member 33 includes a first circular plate 332 slidably mounted inside the transmission cylinder 32. A first damping spring 331 for buffering the pressure of the foot pedal 2 is fixedly installed between the first circular plate 332 and the top wall of the transmission cylinder 32. The foot pedal 2 is disposed at the top of the base 1. A pressure rod 31 is fixedly mounted on the surface of the first circular plate 332. The free end of the pressure rod 31 is rotatably connected to the foot pedal 2.

[0035] When the foot pedal 2 is in use, the pressure is transmitted to the first circular plate 332. When the first circular plate 332 moves, the first damping spring 331 can provide the first buffer for the foot pedal 2. The buffering effect of the first damping spring 331 makes the operation of the foot pedal 2 more comfortable and effortless.

[0036] In some embodiments, the second transmission member 34 is disposed inside the transmission cylinder 32. The second transmission member 34 includes a second circular plate 343 slidably mounted inside the transmission cylinder 32. A second damping spring 342 for buffering the pressure of the foot pedal 2 is fixedly mounted on the surface of the second circular plate 343 near the foot pedal 2. A sealing ring 341 is fixedly mounted on the surface of the second circular plate 343 near the first circular plate 332, and the sealing ring 341 slides on the inner wall of the transmission cylinder 32.

[0037] When the first circular plate 332 moves continuously, it pushes the second circular plate 343 to move. At this time, the second damping spring 342 is compressed, which provides secondary buffering for the foot pedal 2 and provides additional buffering and transmission functions, enhancing the stability and reliability of the throttle control device. The design of the sealing ring 341 ensures the sealing of the transmission cylinder 32 and prevents leakage and interference.

[0038] In some embodiments, a pin 4 for braking is provided on the surface of the second circular plate 343 away from the foot pedal 2. The pin 4 slides through the transmission cylinder 32 and is connected to the braking device. A third circular plate 353 is fixedly installed on the surface of the pin 4. An adjusting block 351 is provided on the outer surface of the transmission cylinder 32. A third damping spring 352 for buffering the pressure of the foot pedal 2 is fixedly installed between the third circular plate 353 and the adjusting block 351.

[0039] When the second circular plate 343 moves continuously, it pushes the ejector pin 4 to move. The ejector pin 4 drives the third circular plate 353 to move, which causes the third damping spring 352 to deform. The addition of the third damping spring 352 further enhances the buffering effect, making the pedal operation more stable and controllable.

[0040] The combination of the first damping spring 331, the second damping spring 342 and the third damping spring 352 enables phased pressure feedback of the accelerator pedal during the pressing process. This design allows the driver to clearly feel the resistance changes at different stages when pressing the accelerator, thereby controlling the degree of accelerator opening more accurately and avoiding excessive throttle due to excessive force, thus significantly improving the safety and stability of operation.

[0041] In some embodiments, an air supply component 59 is provided on the outer surface of the water storage box 58. The air supply component 59 includes an air cylinder 594 installed on the outer surface of the water storage box 58. A connecting pipe 591 is installed between the air cylinder 594 and the water storage box 58. A membrane 592 for air permeability and drainage is provided on the connecting pipe 591. Two pressure-bearing protective members 593 for supporting the structure of the membrane 592 are provided on the surface of the connecting pipe 591 near the membrane 592.

[0042] When the second circular plate 343 squeezes out the water inside the transmission cylinder 32, the air cylinder 594, in conjunction with the membrane 592, can reasonably control the airflow inside the water storage box 58, achieving precise balance and adjustment of the internal pressure of the water storage box 58, ensuring the stability and maximization of the buffering effect. The membrane 592 can allow gas to circulate while reducing water loss, and the pressure-bearing protective component 593 can protect the membrane 592 to prevent damage to the membrane 592 due to excessive pressure.

[0043] In some embodiments, a fourth spring 7 for bearing pressure on the transmission cylinder 32 is fixedly installed between one end of the transmission cylinder 32 and the base 1, and a baffle 6 for protection is fixedly installed between the foot pedal 2 and the fourth spring 7 on the base 1.

[0044] The fourth spring 7 provides additional pressure-bearing and protection to the transmission cylinder 32, enhancing the stability and durability of the throttle control device. The baffle 6 prevents debris and dust from entering the transmission cylinder 32, protecting the integrity and function of the internal structure.

[0045] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of the present invention.
