Description

Technical Field

[0001] The invention relates to the technical field of airport runway pavement maintenance equipment, and in particular to a runway intelligent emergency repair vehicle. Background Art

[0002] Airport pavement repairs are time-sensitive and demanding. Civil airports require that the replacement of panels be completed within 4 hours of suspension and that the conditions for navigation be met. This requires that the process from breaking the panels to pouring be completed within 3 hours. Military airports require even more urgent time to restore craters. In order to meet the requirements, rapid on-site concrete repairs usually use human sea tactics. Mixing fast-hardening concrete requires a lot of machinery and manual labor to weigh sand, gravel, cement, and water and quickly mix, pour, and finish, etc., and the process connection requirements are high. Concrete solidifies quickly and requires a large amount of concrete. The single-time production volume of traditional mixers is not enough, and multiple productions are slow and poorly connected, which may also lead to stratification, making it difficult to guarantee the quality of on-site production.

[0003] Traditional equipment includes shaft-type stirring and drum-type stirring. The average speed of drum-type stirring is 20-35 rpm. Shaft-type stirring equipment can adjust the stirring speed according to actual needs. Since the blades force the materials to stir, the stirring effect is strong. When adding more raw materials at one time for stirring, more energy is consumed, and the blades and motors are damaged. In summary, single mixing and stirring cannot meet the requirements of rapid production and continuous production.

[0004] Therefore, this application provides a runway intelligent repair vehicle to meet the needs. Summary of the invention

[0029] Stirring component 6: Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, it is used for the third mixing and stirring of the raw materials in the mixing kettle 81; The stirring assembly 6 includes a stirring shaft 61 and a second motor 65. The second motor 65 is installed on the carriage 11. The output end of the second motor 65 is connected to the stirring shaft 61 through a clamping mechanism. The stirring shaft 61 is installed with paddles 62. The paddles 62 are provided in multiple groups, and the multiple groups of paddles 62 are all located inside the mixing kettle 81.

[0030] The setting of the clamping structure can make the stirring shaft 61 and the clamping seat 64 quickly disassembled and assembled, and adapt to the two states of the mixing kettle 81, namely the tilted and vertical states, corresponding to the second and third mixing of the raw materials; The clamping mechanism includes a clamping joint 67 and a clamping seat 64. The clamping seat 64 is installed at the output end of the second motor 65. The clamping joint 67 is installed on the top of the stirring shaft 61. The bottom of the clamping seat 64 is provided with a clamping groove 66 adapted to the clamping joint 67. The clamping groove 66 is a T-shaped groove, including an inclined guide section and a horizontally arranged driving section. The setting of the guide section enables the clamping joint 67 on the stirring shaft 61 to slide into the guide section first when the mixing kettle 81 is reset. When the mixing kettle 81 is completely reset, the clamping joint 67 is located in the driving section. At this time, the gear 63 is separated from the tooth groove and does not affect the rotation of the stirring shaft 61.

[0031] The mixing assembly 8 also includes a support rod 82 and a mounting ring 86. The top of the mixing kettle 81 is connected to the mounting ring 86 via the support rod 82. The mounting ring 86 is coaxially arranged with the mixing kettle 81, and a through hole is opened on the mounting ring 86 for the stirring shaft 61 to pass through.

[0032] A gear 63 is also mounted on the stirring shaft 61 , and a tooth groove meshing with the gear 63 is formed on the mounting ring 86 . When the clamping joint 67 is located in the driving section of the clamping groove 66 , the gear 63 is separated from the tooth groove and does not affect the rotation of the stirring shaft 61 .

[0033] Working principle of the utility model: before use, the retractable curtain 13 on the carriage 11 is folded up, the inspection port 12 is opened, and the raw materials required for concrete preparation, including stone, grinding wheel, cement, water and additives, are added to the raw material bin 2 on the vehicle body 1. After the addition is completed, the retractable curtain 13 is extended, the inspection port 12 is closed, and it is ready for use; When receiving the construction instruction, the vehicle body 1 is started, and the driver drives the vehicle body 1 to the construction site. The assistant driver inputs various raw material parameters required for preparing concrete into the PLC control center, and starts the mixing program. Under the control of the PLC control center, the first motor 55 in the support assembly 5 rotates, driving the mounting frame 53 to rotate on the support frame 52, thereby driving the mixing kettle 81 to rotate along with the mounting frame 53, and the mixing kettle 81 slides on the support seat 51. Due to the action of the second rolling ball 56, the friction between the mixing kettle 81 and the support seat 51 is reduced. Driven by the first motor 55, the mixing kettle 81 tilts 30 degrees, and the first motor 55 stops working and self-locks. When the mixing kettle 81 rotates, the support rod 82 and the mounting ring 86 drive the stirring shaft 61 to rotate together, so that the stirring shaft 61 drives the clamping joint 67 on the top to slide out of the clamping groove 66 of the clamping seat 64, and the stirring shaft 61 drives the gear 63 to fit into the tooth groove on the mounting ring 86 under the action of gravity, so as to limit the stirring shaft 61; The first telescopic cylinder 44 in the material introducing assembly 4 is controlled to work and extend, driving the material introducing plate 43 to slide on the mounting frame 41, so that the output end of the material introducing plate 43 is located above the mixing kettle 81, and the raw materials can be smoothly introduced into the mixing kettle 81; The screw conveyor 31 is controlled to add the stone and sand in the raw material bin 2 to the receiving plate 42 of the material introduction component 4. The stone and sand fall on the receiving plate 42 under the conveyance of the screw conveyor 31. The sand and stone are preliminarily mixed on the receiving plate 42. The raw materials roll along the receiving plate 42 and the introducing plate 43 under the action of their own gravity. While the raw materials are preliminarily mixed, they are added to the mixing kettle 81. In order to prevent the raw materials from being blocked on the receiving plate 42 and the guiding plate 43, the second telescopic cylinder 71 in the driving assembly 7 is controlled to work and extend, driving the mounting plate 72 to move toward the mixing kettle 81, and making the roller 73 contact the outer wall of the mixing kettle 81. Since the telescopic end of the second telescopic cylinder 71 is hinged to the mounting plate 72 through the hinge seat 76, when the second telescopic cylinder 71 is extended, the roller 73 can fit the outer wall of the mixing kettle 81. Under the self-locking effect of the first motor 55, the mixing kettle 81 will not be pushed to rotate around the support frame 52. The third motor 74 is controlled to work and rotate, driving the roller 73 to rotate, and the friction between the roller 73 and the outer wall of the mixing kettle 81 drives the mixing kettle 81 to rotate. The first rolling ball 54 on the mounting frame 53 rolls in the annular groove 85 on the mixing kettle 81 to reduce the resistance of the mixing kettle 81 when rotating; under the action of the rotating pipe joint 84, the mixing kettle 81 rotates without affecting the normal use of the discharge pipe 83; When the mixing kettle 81 rotates, the support rod 82 and the mounting ring 86 are driven to rotate together with the mixing kettle 81. The support rod 82 contacts the guide plate 43 during the rotation process, and pushes the guide plate 43 to drive the receiving plate 42 to rotate around the hinge with the mounting frame 41. The torsion spring stores force. When the support rod 82 is separated from the guide plate 43, the guide plate 43 and the receiving plate 42 are reset under the elastic force of the torsion spring. At the same time, the guide plate 43 collides with the mounting frame 41 to generate vibration, so as to avoid the accumulation of raw materials on the guide plate 43 and the receiving plate 42, so that the raw materials can be smoothly added to the mixing kettle 81. At the same time, the metering and conveying pipeline 32 is controlled to add a small amount of water into the mixing kettle 81 to perform secondary mixing of the stone, sand and water. When the mixing kettle 81 rotates, the stirring shaft 61 rotates together with the mixing kettle 81 under the limiting effect of the gear 63, and the paddle 62 on the stirring shaft 61 plays a supporting and blocking role, so that the stone, sand and water in the mixing kettle 81 can be fully mixed; at this time, the rotation speed of the mixing kettle 81 is 30 rpm; Since cement and additives are not added to the mixing kettle 81, there will be no solidification between the stone, sand and water; when the vehicle body 1 is about to arrive at the construction site, the screw conveyor 31 and the metering conveying pipeline 32 are controlled to add cement and the remaining proportion of water into the mixing kettle 81, and the first motor 55 is controlled to release the self-locking and drive the mixing kettle 81 to reset. During the resetting process of the mixing kettle 81, the clamping joint 67 contacts the clamping groove 66 on the clamping seat 64, and under the action of the guide section inclined in the clamping groove 66, the stirring shaft 61 is driven to move upward with the clamping joint 67. When the mixing kettle 81 is reset, that is, the mixing kettle 81 is in a vertical state, at this time, the clamping joint 67 is located in the driving section horizontally arranged in the clamping groove 66, and the gear 63 completely slides out of the tooth groove in the mounting ring 86, that is, the tooth groove on the mounting ring 86 no longer limits the gear 63; Control the third motor 74 to stop working, and control the second telescopic cylinder 71 to retract and reset; The second motor 65 is controlled to work, and the agitator shaft 61 and the paddle 62 are driven to mix the raw materials in the mixing kettle 81 through the card seat 64 and the card joint 67. At this time, the second motor 65 drives the agitator shaft 61 to rotate. Since water is added during the second mixing, the raw materials in the mixing kettle 81 have a certain fluidity at this time, which is convenient for the second motor 65 to drive the agitator shaft 61 and the paddle 62 to stir the raw materials. The working time of the second motor 65 is shortened, and the initial torque during rotation is reduced. The third mixing and stirring can be completed without the high-power second motor 65, thereby reducing energy loss. At the same time, the two mixing methods are used in combination, and the raw materials are mixed more fully. The solenoid valve at the discharge port 87 is controlled to open, and the mixed concrete is discharged through the discharge pipe 83 for road repair.
