Description

Technical Field

[0001] This utility model relates to the field of teaching model technology, and in particular to a physical operation and training device for coal mining machines. Background Technology

[0002] In order to improve the skills and standardize the operation of coal mining machine operators and ensure that trainees master the standardized operating procedures, coal mining machine physical operation training devices are usually used to conduct safety training and risk prevention for coal mining machine operators. Existing coal mining machine physical operation training devices usually consist of a simulated scraper conveyor, the main body of the coal mining machine, an operation panel, a monitor and a keyboard.

[0003] However, with the current traditional coal mining machine operation training devices, operators are prone to standing haphazardly during the training process, such as being too close or too far away, or operating sideways, which leads to incorrect operating habits. At the same time, when operating the coal mining machine operation training device, operators may operate it before standing still or multiple people may touch the control panel at the same time, resulting in chaotic training data, affecting the efficiency and standardization of the training, and making it inconvenient to use. Utility Model Content

[0004] In view of this, the present invention provides a physical operation training device for coal mining machines, which has a control pedal that only exposes the operation panel when the operator stands in the designated area. When standing in the operation area of ​​the operation panel, the operator steps down the control pedal, causing the control pedal to slide within the protective frame and compress the return spring. After the control pedal is stepped down, pressure is applied to the pressure sensor. After the pressure sensor receives pressure, it transmits a signal to the control system. The control system then activates the electric push rod. The method of receiving the signal from the pressure sensor and driving the electric push rod through the control system is a common technique used by those skilled in the art, and therefore will not be described in detail here. The electric push rod drives the mounting frame to move. During the movement of the mounting frame, the control rack moves, which in turn drives the control gear to rotate. As the control gear rotates, the protective baffle flips over, exposing the operation panel.

[0005] This utility model provides a practical operation training device for coal mining machines, specifically including: a simulated scraper conveyor; two scraper chains symmetrically arranged inside the simulated scraper conveyor; a coal mining machine body slidably connected to the upper part of the simulated scraper conveyor; both scraper chains are fixedly connected to the coal mining machine body; a protective frame is fixedly connected to the front of the simulated scraper conveyor; a mounting plate is fixedly connected to the lower part of the front end face of the simulated scraper conveyor; the mounting plate is fixedly connected to the protective frame; an operation panel is provided on the front end face of the coal mining machine body; a display screen body is provided at the rear of the top end face of the coal mining machine body; a keyboard body is provided at the front of the top end face of the coal mining machine body; the keyboard body and the display screen body are aligned.

[0006] Optionally, a guide plate is slidably connected to the lower part of the protective frame; a control pedal is fixedly connected to the outside of the guide plate; the control pedal is aligned with the position of the mounting plate; a set of return springs is fixedly connected to the bottom end face of the guide plate; the end of the return spring is fixedly connected to the top end face of the mounting plate.

[0007] Optionally, the top surface of the mounting plate is provided with multiple sets of pressure sensors; two electric push rods are symmetrically bolted to the front end of the coal mining machine body; the two electric push rods are electrically connected to the multiple sets of pressure sensors respectively; and a mounting bracket is fixedly connected to the end of the output shaft of each of the two electric push rods.

[0008] Optionally, a control rack is fixedly connected to the top surface of each of the two mounting brackets; a protective baffle is hinged to the front surface of the coal mining machine body; the protective baffle is aligned with the operation panel; two control gears are symmetrically and coaxially fixedly connected to the outside of the protective baffle's rotating shaft; the two control gears mesh with the two control racks respectively.

[0009] Optionally, a positioning groove is provided at the rear of the top surface of the main body of the coal mining machine; the main body of the display screen is set in the positioning groove; a connecting slide plate is slidably connected in the positioning groove; two positioning pressure plates are symmetrically and fixedly connected to the front end of the connecting slide plate; a fixing frame is fixedly connected to the rear end of the main body of the coal mining machine; a guide slide rod is fixedly connected in the center of the rear end of the connecting slide plate; the guide slide rod is slidably connected in the fixing frame; multiple sets of control springs are fixedly connected to the rear end of the connecting slide plate; the ends of the multiple sets of control springs are all fixedly connected to the inner side of the fixing frame.

[0010] Optionally, a limiting groove is provided at the front of the top end of the main body of the coal mining machine; the keyboard body is set in the limiting groove; and two retrieval grooves are symmetrically provided outside the limiting groove.

[0011] Beneficial effects

[0012] In use, when operators are undergoing training and assessment, they step on a control pedal upon standing in the operating area of ​​the control panel. The pressure pedal applies pressure to a pressure sensor, which in turn causes a series of transmission actions to flip a protective baffle, exposing the control panel. This ensures that the control panel can only be operated when the operator is standing in the designated operating area, guaranteeing that trainees operate in a standard posture and preventing operational deviations caused by arbitrary positioning. It also prevents accidental touches or unauthorized operation of the control panel, making it particularly suitable for training scenarios involving multiple people. This design avoids the risk of safety simulation accidents caused by misoperation, effectively improving the safety and practicality of the coal mining machine operation training and assessment device.

[0013] The positioning plate and positioning groove work together to position the display screen body. When the display screen body needs to be replaced, the guide slide is pulled, and then a series of transmissions release the limit on the display screen body. At this time, the display screen body can be taken out of the positioning groove. The setting of the limiting groove can limit the keyboard body to prevent the keyboard body from shifting during use. The setting of the retrieval groove can easily remove the keyboard body from the limiting groove, avoiding arbitrary changes in the position of the display screen body and keyboard body, ensuring the efficiency and safety of human-computer interaction, and effectively improving the convenience of the coal mining machine operation training device.

[0031] A guide slide plate 106 is slidably connected to the lower part of the protective frame 103; a control pedal 109 is fixedly connected to the outside of the guide slide plate 106; the control pedal 109 is aligned with the position of the mounting plate 104; a set of return springs 107 are fixedly connected to the bottom end face of the guide slide plate 106; the end of the return spring 107 is fixedly connected to the top end face of the mounting plate 104.

[0032] Multiple pressure sensors 108 are installed on the top surface of the mounting plate 104; two electric push rods 110 are symmetrically bolted to the front surface of the coal mining machine body 102; the two electric push rods 110 are electrically connected to the multiple pressure sensors 108 respectively; a mounting bracket 124 is fixedly connected to the end of the output shaft of each of the two electric push rods 110.

[0033] A control rack 111 is fixedly connected to the top surface of each of the two mounting brackets 124; a protective baffle 123 is hinged to the front surface of the coal mining machine body 102; the protective baffle 123 is aligned with the position of the operating panel 105; two control gears 112 are symmetrically and coaxially fixedly connected to the outside of the rotating shaft of the protective baffle 123; the two control gears 112 mesh with the two control racks 111 respectively.

[0034] A positioning groove 113 is provided at the rear of the top surface of the coal mining machine body 102; the display screen body 114 is set in the positioning groove 113; a connecting slide plate 117 is slidably connected in the positioning groove 113; two positioning pressure plates 119 are symmetrically and fixedly connected to the front end of the connecting slide plate 117; a fixing frame 115 is fixedly connected to the rear end of the coal mining machine body 102; a guide slide rod 116 is fixedly connected in the center of the rear end of the connecting slide plate 117; the guide slide rod 116 is slidably connected in the fixing frame 115; multiple sets of control springs 118 are fixedly connected to the rear end of the connecting slide plate 117; the ends of the multiple sets of control springs 118 are all fixedly connected to the inner side of the fixing frame 115.

[0035] The specific usage and function of this embodiment: The main body 102 of the coal mining machine is made of steel structure, with the main components having a steel plate thickness of 3mm and other steel plates having a thickness of 2mm. The metal surface of the equipment is sprayed with metallic paint, resulting in a beautiful appearance, accurate structure, and durability. The electrical control system uses national standard parts and conforms to national standards. The simulated scraper conveyor 1 is made of steel structure and metal, with scrapers made of wear-resistant, low-noise materials, ensuring smooth operation and safety. All surfaces are treated with sprayed metallic paint. The scraper chain 101 can run in the forward direction. The specific design closely resembles the actual machine, and the appearance and structure must conform to the actual scraper conveyor structure. When the operator is undergoing operation training, upon standing in the operating area of ​​the control panel 105, they will step on the control pedal 109, causing the control pedal 109 to drive the guide slide. 106 slides within the protective frame 103 and compresses the return spring 107. When the control pedal 109 is pressed, it applies pressure to the pressure sensor 108. Upon receiving pressure, the pressure sensor 108 transmits a signal to the control system, which then activates the electric push rod 110. The control system receives the signal from the pressure sensor 108 and drives the electric push rod 110 (this is prior art and will not be elaborated upon). The electric push rod 110 moves the mounting frame 124, which in turn moves the control rack 111. As the control rack 111 moves... The movement of the control gear 112 will cause the control gear 112 to rotate. As the control gear 112 rotates, it will cause the protective baffle 123 to flip, exposing the operation panel 105. This ensures that the operation panel 105 can only be operated when the operator is standing in the designated operation area. The scraper chain 101 is connected to an external power mechanism, which can drive the main body of the coal mining machine 102 to move. At the same time, when the operator moves away from the pressure sensor 108, the control system recognizes it as a non-operational state and sends a command to the electric push rod 110 again to reset the electric push rod 110, thereby driving the protective baffle 123. When plate 123 is closed, it blocks the operation panel 105. The positioning plate 119 and the positioning groove 113 can be used to position the display screen body 114. When the display screen body 114 needs to be replaced, the guide slide 116 is pulled, which pulls the connecting slide 117 and squeezes the control spring 118. As the connecting slide 117 moves, it will drive the positioning plate 119 to move. As the positioning plate 119 moves, it will release the restriction on the display screen body 114. Only then can the display screen body 114 be taken out from the positioning groove 113.

[0036] Example 2:

[0037] Based on Example 1, please refer to Figures 1 to 4 It includes: a limiting groove 120 and a picking groove 121. The limiting groove 120 is opened at the front of the top end of the coal mining machine body 102; the keyboard body 122 is set in the limiting groove 120; and two picking grooves 121 are symmetrically opened on the outside of the limiting groove 120.

[0038] The specific usage and function of this embodiment are as follows: the setting of the limiting groove 120 can limit the keyboard body 122 to prevent the keyboard body 122 from shifting during use, and the setting of the take-up groove 121 can facilitate the removal of the keyboard body 122 from the limiting groove 120.

[0039] The following points should be noted in this article:

[0040] 1. The accompanying drawings of this embodiment only involve the structures involved in this embodiment; other structures can refer to the general design.

[0041] 2. Where there is no conflict, this embodiment and the features in the embodiment can be combined with each other to obtain new embodiments.

[0042] The above are merely specific implementations of this embodiment, but the protection scope of this embodiment is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this embodiment should be included within the protection scope of this embodiment. Therefore, the protection scope of this embodiment should be determined by the protection scope of the claims.
