Description

Technical Field

[0001] This invention relates to the field of flooring machine technology, specifically a mining flooring machine. Background Technology

[0002] The construction of underground and surface auxiliary facilities in mines is a crucial step in mine construction and operation, and its quality directly affects mine transportation efficiency, equipment operation safety, and the stability of the working environment. As the core equipment for flooring construction, mining flooring machines must adapt to the complex working environment of mines while meeting the demands for high-intensity, high-efficiency, and high-precision construction.

[0003] While existing floor slab machines meet users' needs to some extent, certain shortcomings remain. These include: low integration of operations, with most requiring separate material distribution, vibration, and leveling equipment for coordination. This makes equipment coordination difficult, complicates the construction process, and significantly reduces efficiency. Furthermore, insufficient leveling accuracy is a concern. Traditional floor slab machines suffer from poor vibration stability in their vibration mechanisms, lacking effective damping and buffering designs. This makes them susceptible to uneven ground conditions, leading to uneven compaction. Additionally, the material distribution mechanism is ineffective, resulting in uneven material distribution and further affecting the leveling accuracy. Finally, poor steering flexibility is a significant drawback, especially in narrow mining areas. In situations with numerous passageways and turns, the traditional floor paving machine's frame connection structure has limited steering angle and insufficient operational flexibility, making it difficult to adapt to the steering needs of complex operating scenarios. Furthermore, its power adaptability is poor. Mining floor paving construction requires handling foundation surfaces of varying hardness and material thicknesses; the powertrain output of traditional floor paving machines is inflexible in its adjustment, failing to accurately match the workload and easily leading to insufficient power or energy waste. Fifthly, the equipment suffers from poor stability. During operation, factors such as material impact and ground vibration can cause the equipment to bump and shift, affecting construction quality and increasing operational safety risks. Therefore, this invention designs a mining floor paving machine to solve the above problems. Summary of the Invention

[0004] This invention provides a mining flooring machine that effectively solves the problems mentioned in the background art, such as low integration of operations, the need for most flooring machines to work in conjunction with separate material distribution equipment, vibrating equipment, and leveling equipment, resulting in difficult equipment coordination, cumbersome construction processes, significantly reduced construction efficiency, and insufficient leveling accuracy. Traditional flooring machines also suffer from poor vibration stability in their vibrating mechanisms, lacking effective damping and buffering designs, making them susceptible to uneven vibration due to ground undulations. Furthermore, the material distribution mechanism has poor distribution efficiency, further affecting the leveling accuracy of the flooring. Additionally, they lack steering flexibility, which is problematic in narrow mining areas. In situations with numerous passageways and turns, the traditional floor paving machine's frame connection structure has limited steering angle and insufficient operational flexibility, making it difficult to adapt to the steering needs of complex work scenarios. Furthermore, its power adaptability is poor. Mining floor paving construction requires dealing with base surfaces of varying hardness and material thicknesses. The powertrain output of traditional floor paving machines is not flexibly adjustable and cannot accurately match the work load, easily leading to insufficient power or energy waste. Fifth, the equipment has poor stability. During operation, factors such as material impact and ground vibration can easily cause the equipment to bump and shift, which not only affects the construction quality but also increases operational safety risks.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mining flooring machine, comprising a flooring head and a front frame, wherein the front frame is provided at one end of the flooring head, a driver's cab is provided at the top of the front frame, a rear frame is provided at one end of the front frame, the rear frame and the front frame are connected by a hinged steering mechanism, a powertrain is provided at the top of the rear frame, a rear frame traveling mechanism is provided at the bottom of the rear frame, a rear material distribution and leveling mechanism is provided at one end of the rear frame, and a front frame traveling mechanism is provided at the bottom of the front frame.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a scientific and reasonable structure and is safe and convenient to use: The mining flooring machine integrates the vibration and conveying functions of the flooring machine head and the material distribution and leveling functions of the material distribution and leveling mechanism at the rear of the machine. No additional auxiliary equipment is required. It can realize integrated construction of material conveying, vibration compaction, uniform material distribution and leveling, which greatly simplifies the construction process, improves construction efficiency and reduces the difficulty of equipment coordination.

[0013] The floor compactor head uses a hydraulic vibrator to provide stable vibration force. Combined with the double buffering effect of the first and second spring dampers, it can effectively offset the impact of ground undulations on the compaction operation, ensuring uniform compaction by the vibrating plate. The spiral conveyor blades can achieve uniform material transportation, and the rear distribution cone can accurately distribute and flatten the material. The entire process from conveying, compaction to distribution and flattening is optimized, significantly improving the flatness and density of the mining floor.

[0021] The flooring machine head 1 includes a lifting cylinder 101, a mounting frame 102, a drive cylinder 103, a vibrating plate 104, a hydraulic vibrator 105, a first spring damper 106, a fixing frame 107, a second spring damper 108, a hydraulic motor 109, a chain connection mechanism 110, and a spiral conveyor blade 111. Lifting cylinders 101 are screwed onto both ends of one side of the front frame 2. The bottoms of the two lifting cylinders 101 are connected by a mounting bracket 102. A drive cylinder 103 is rotatably connected to one end of the mounting bracket 102, and a vibrating plate 104 is rotatably connected to the other end of the drive cylinder 103. The entire concrete placing device can be raised and lowered on one side according to ground conditions to adjust the elevation angle of the placing device to meet the needs of sloping road surfaces. A hydraulic vibrator 105 is installed on the top of the vibrating plate 104. The vibrating plate 104 is used for leveling the concrete surface, and the vibration force can be adjusted according to... The vibration force of the vibrator is adjusted according to the different concrete grades. The vibrating plate and the concrete placing device are elastically connected. By adjusting the vibration force of the vibrator, square corrugations are formed on the concrete surface to ensure the quality of the concrete surface. The mounting frame 102 is equipped with a first spring damper 106 at both ends. A fixing frame 107 is installed at one end of several adjacent first spring dampers 106 by screws. The bottom ends of the fixing frame 107 are equipped with second spring dampers 108 by screws. The bottoms of multiple second spring dampers 108 are connected by a vibrating plate 104. A hydraulic motor 109 is fixedly connected to one end of the mounting frame 102. A chain connection mechanism 110 is fixedly connected to the output shaft of the hydraulic motor 109. A spiral conveyor blade 111 is fixedly connected to the bottom of the chain connection mechanism 110. The spiral conveyor blade 111 is rotatably connected to the bottom of the mounting frame 102. The hydraulic motor 301 drives the spiral conveyor blade 302 to rotate via the chain. The spiral conveyor's rotation speed can be adjusted according to different concrete grades. The rotating spiral blades evenly spread the concrete onto the roadbed, while simultaneously agitating and expelling air bubbles from within the concrete.

[0022] The rear material distribution and leveling mechanism 7 includes a support frame 701, a hydraulic lifting cylinder 702, a moving frame 703, and a material distribution cone 704; A support frame 701 is installed at one end of the rear frame 4 with screws. A hydraulic lifting cylinder 702 is installed at one end of the support frame 701 with screws. A movable frame 703 is installed at the top of the hydraulic lifting cylinder 702 with screws. A distribution cone 704 is installed at one end of the movable frame 703 with screws for pre-leveling concrete. The concrete mixer truck piles concrete at the rear of the truck, and the distribution cone 401 pre-levels the concrete pile. The thickness of the pre-leveled concrete can be adjusted according to the thickness requirements of the road surface concrete.

[0023] The cab 3 is used by the operator to control the equipment, the articulated steering mechanism 8 is used to realize the relative rotation between the front frame 2 and the rear frame 4, and the powertrain 5 is used to provide power to the equipment.

[0024] The 704 material distribution cone has a triangular cross-section, which facilitates the distribution of materials.

[0025] The equipment is driven to the mining floor construction area. The operator enters the cab 3, starts the powertrain 5, and checks whether the hydraulic system, walking mechanism, and steering mechanism are operating smoothly to ensure that the equipment is in normal working condition. The parameters of each mechanism are adjusted according to the construction requirements: the lifting cylinder 101 is controlled by the control system in the cab 3. The lifting cylinder 101 drives the mounting frame 102 to move up and down, thereby adjusting the distance between the vibrating plate 104 and the ground to achieve a suitable vibration height. The drive cylinder 103 is controlled to drive the vibrating plate 104 to rotate, adjusting the vibration angle of the vibrating plate 104 to adapt to different ground slope requirements. The hydraulic lifting cylinder 702 of the rear material distribution and leveling mechanism 7 is controlled to drive the moving frame 703 to move up and down, thereby adjusting the height of the material distribution cone 704 to match the material laying thickness requirements.

[0026] The hydraulic motor 109 is started, and the output shaft of the hydraulic motor 109 drives the spiral conveyor blades 111 to rotate through the belt connection mechanism 110. The spiral conveyor blades 111 evenly convey the material to be laid to the vibration area. At the same time, the hydraulic vibrator 105 is started, and the hydraulic vibrator 105 drives the vibrating plate 104 to generate high-frequency vibration, which vibrates and compacts the material conveyed to the designated area. During the operation, the first spring damper 106 and the second spring damper 108 play a buffering role to offset the impact force generated by ground undulation and vibration, ensuring that the vibrating plate 104 vibrates smoothly and evenly. The operator controls the front frame traveling mechanism 9 and the rear frame traveling mechanism 6 to move synchronously through the cab 3, so that the equipment can move smoothly along the construction direction and realize continuous vibration operation.

[0027] After the material has been vibrated, it moves with the equipment to the material distribution and leveling mechanism 7 area at the rear of the vehicle. The material distribution cone 704 evenly distributes the vibrated material, dispersing the accumulated material to a specified width range to achieve flat laying of the material. If it is necessary to adjust the construction direction, the operator controls the articulated steering mechanism 8 through the cab 3. The articulated steering mechanism 8 drives the front frame 2 and the rear frame 4 to rotate relative to each other, realizing flexible steering of the equipment and adapting to the steering needs of complex mining operation areas.

[0028] After construction is completed, turn off the hydraulic vibrator 105 and hydraulic motor 109 in sequence to stop material conveying and vibration operation. Adjust the lifting cylinder 101 and hydraulic lifting cylinder 702 through the control system to raise the vibrating plate 104 and the material distribution cone 704 to a safe height. Turn off the power assembly 5, check whether there is any damage or material residue in each part of the equipment, clean the material impurities on the surface of the equipment, drive the equipment to the designated storage area, and complete the work and storage.
