Description

Technical Field

[0001] This utility model relates to the field of trackless vehicles for non-coal mines, specifically to an integrated control cabinet for the electrical system of trackless vehicles for non-coal mines. Background Technology

[0002] Trackless vehicles in non-coal mines are self-propelled tire vehicles specifically designed for use in inclined ramps and / or tunnels of underground metal and non-metal mines. These vehicles are primarily used for transporting personnel, materials, or performing other mining operations. They are typically equipped with advanced braking systems to ensure safety and reliability in complex underground environments. Trackless vehicles in non-coal mines need to be equipped with integrated electrical system control cabinets. These integrated control cabinets can connect various sensors and monitoring devices on the vehicle to monitor the vehicle's operating status and environmental parameters in real time. They can also be managed and controlled through a unified control cabinet, improving the reliability and accuracy of safety equipment and providing more comprehensive protection for the safe operation of the vehicle. Due to the harsh environment of non-coal mines, with high levels of dust in the air, the integrated electrical system control cabinet of the trackless vehicle is exposed when it is not in motion. As a result, dust can easily enter the control cabinet and accumulate on the contact surface of the relays, forming a physical barrier that prevents the contacts from making proper electrical connections and thus hinders the normal transmission of control signals. Dust can also affect the accuracy of sensors by obstructing the optical path or detection area of ​​the sensing elements, weakening or distorting the intensity of the light signal received by the sensors, thereby causing misjudgments in the vehicle's control system. Therefore, this paper proposes an integrated electrical system control cabinet for trackless vehicles in non-coal mines to address the above problems. Utility Model Content

[0016] Please see Figure 1-7 This utility model provides a technical solution: An integrated control cabinet for the electrical system of a trackless vehicle in a non-coal mine includes a control cabinet body 1, a supporting base plate 2 at the bottom of the control cabinet body 1, a telescopic cover 3 on the outer side of the control cabinet body 1, telescopic components 4 symmetrically arranged on the left and right sides of the control cabinet body 1, and buffer components 5 at the four corners of the bottom of the supporting base plate 2. The telescopic components 4 include telescopic support rods 41 set at the four corners of the top of the supporting base plate 2, and electric push rods 42 between adjacent telescopic support rods 41. A connecting sleeve 43 is sleeved on the top output end of the electric push rod 42. The two ends of the connecting sleeve 43 are sleeved on the top movable ends of the telescopic support rods 41, and both ends of the connecting sleeve 43 are fixedly connected to the top inner side of the telescopic cover 3. The bottom end of the telescopic cover 3 is fixedly connected to the top end of the supporting base plate 2. The bottom ends of the telescopic support rods 41 and the bottom ends of the electric push rods 42 are both fixedly connected to the top end of the supporting base plate 2.

[0017] As a further implementation of this solution, a supporting vertical plate 6 is fixedly connected to the top rear end of the supporting base plate 2, and a supporting top plate 7 is fixedly connected to the top of the supporting vertical plate 6. The specifications of the supporting top plate 7 are larger than those of the telescopic shield 3. The supporting top plate 7 can be used in conjunction with the telescopic shield 3. When the telescopic shield 3 is in the extended protective state, its top will fit and seal against the bottom of the supporting top plate 7 to enhance the protective effect of the telescopic shield 3.

[0018] As a further implementation of this solution, the telescopic support rod 41 includes a fixed rod 411 and a movable rod 412. A first air hole 413 is provided at the bottom center of the fixed rod 411. The telescopic support rod 41 can move synchronously with the drive of the electric push rod 42, thereby driving the telescopic cover 3 to extend and retract synchronously.

[0019] As a further implementation of this solution, the buffer assembly 5 includes a fixed cylinder 51 and a movable column 52. The top end of the movable column 52 is fixedly connected to the bottom end of the supporting base plate 2, and the bottom end penetrates the top wall of the fixed cylinder 51 and extends into the inner cavity of the fixed cylinder 51. A first sealing plate 53 is fixedly connected to the bottom outer side of the movable column 52. A second sealing plate 54 is provided below the first sealing plate 53. Sealing rings are provided on the outer sides of both the first sealing plate 53 and the second sealing plate 54. An air chamber 55 is formed between the first sealing plate 53 and the second sealing plate 54. Second air holes 21 are opened at the four corners of the supporting base plate 2. The center of the movable column 52 penetrates... The device has a third vent 56. A buffer spring 57 is fixedly connected to the bottom of the inner cavity of the fixed cylinder 51. The top of the buffer spring 57 is fixedly connected to the bottom of the second sealing plate 54. A first through hole 58 is opened on the top of the fixed cylinder 51. A second through hole 59 is passed through the bottom of the side wall of the fixed cylinder 51. The buffer assembly 5 can provide good buffering capacity for the control cabinet body 1 when the trackless vehicle is in motion, preventing the trackless vehicle from bumping in the road conditions and affecting the control cabinet body 1. It also avoids the loosening of the wiring terminals, the offset of the relay contacts, or even the breakage of the PCB solder joints in the control cabinet body 1, which would cause the system to be unstable.

[0020] Workflow: The control cabinet body 1 connects various sensors and monitoring devices of the trackless vehicle, and manages and controls the trackless vehicle. The support base plate 2 supports the various components. The telescopic cover 3 can adjust the opening or closing state of the control cabinet body 1 through its telescopic state. When the control cabinet body 1 is in use, the telescopic cover 3 is adjusted to the retracted state, exposing the control cabinet body 1 for use. When the control cabinet body 1 is not in use, the telescopic cover 3 is adjusted to the extended state, sealing and protecting the control cabinet body 1. The telescopic component 4 can provide adjustment driving force for the different states of the telescopic cover 3. Taking protection as an example, activating the electric push rod 42 causes the electric push rod 42 to extend upwards. The extension of the electric push rod 42 will... The connecting sleeve 43 drives the movable rod 412 in the telescopic support rod 41 to move upward synchronously, and at the same time drives the telescopic cover 3 to move upward synchronously until the telescopic cover 3 moves to the top and fits against the bottom of the support plate 7 at the top of the support vertical plate 6. At this time, the telescopic cover 3, together with the support plate 7, can seal and protect the control cabinet body 1, thereby providing good sealing and protection for the control cabinet body 1, blocking the entry of dust in the air, and avoiding various effects caused by dust entering the control cabinet body 1. Conversely, the buffer component 5 can provide good buffering capacity for the control cabinet body 1 when the trackless vehicle is in motion, preventing the trackless vehicle from bumping in uneven road conditions and affecting the control cabinet body 1. When the car is in motion, in order to make the control cabinet body 1... When the cabinet body 1 is exposed for use, the telescopic cover 3 is driven by the electric push rod 42 to retract the movable rod 412 towards the fixed rod 411, thus adjusting the telescopic cover 3 to the retracted state. When the movable rod 412 retracts, it compresses the gas inside the fixed rod 411. Since the first air hole 413, the second air hole 21, and the third air hole 56 are of the same specifications and correspond in position, the air chamber 55 is connected to the inner cavity of the fixed rod 411 through the first air hole 413, the second air hole 21, and the third air hole 56. The gas then enters the third air hole 56 through the first air hole 413 and the second air hole 21, and finally enters the air chamber 55 in the fixed cylinder 51 through the third air hole 56. The gas inside the air chamber 55 expands and presses down on the second sealing plate 54 and the buffer spring. When compression occurs at point 57, the buffer spring 57 deforms to a certain extent. The first sealing plate 53 and the movable column 52 move upward a small distance, allowing the gas above the first sealing plate 53 to escape through the first through hole 58. Since the fixed cylinder 51 is fixed to the trackless vehicle, vibrations during vehicle movement cause the movable column 52 and the first sealing plate 53 to move downward. The first sealing plate 53 compresses the gas inside the air chamber 55, providing a damping effect through the gas's resistance. Simultaneously, the expanding gas presses down on the second sealing plate 54 and compresses the buffer spring 57 again, providing a cushioning effect. At this point, the gas below the second sealing plate 54 escapes through the second through hole 59. Due to the smaller diameter of the second through hole 59...Therefore, it plays a certain role in limiting the flow of gas during the outflow process, and further plays a role in shock absorption, thereby buffering the vibration generated by the trackless vehicle during operation and preventing system instability caused by loose wiring terminals, misaligned relay contacts, or even broken PCB solder joints in the control cabinet body 1.
