Description

Technical Field

[0001] This invention relates to the field of ice-breaking vehicle technology, and in particular to an airport road surface ice-breaking system. Background Technology

[0002] As is well known, when airport roads are icy, the friction between aircraft tires and the runway decreases, causing aircraft to lose control, easily change takeoff direction, and in severe cases, even rollover. In such cases, airports need to close runways and intensify de-icing efforts to ensure flight safety. Existing snow melting and de-icing methods mainly include chemical and mechanical methods. Chemical methods primarily use de-icing agents to melt snow and ice; however, the salts in de-icing agents are highly corrosive to infrastructure. After using de-icing agents, road surfaces are prone to potholes and damage, increasing infrastructure maintenance costs. Mechanical methods use de-icing devices to break up the ice surface and then collect the ice fragments. Airport roads are relatively flat, which is conducive to de-icing operations. However, existing de-icing devices still require manual collection of ice fragments after breaking up the ice surface, resulting in low efficiency. In cold weather (-20 to 30°C), if the ice fragments are not cleared in time, the broken ice surface will re-ic and require rework.

[0003] For example, Chinese Patent (Announcement No.: CN108824334A) discloses a road sweeping, snow removal, and ice breaking vehicle. This patent includes a snowplow, an ice breaking turntable, a spiral ice scraper, a sweeping turntable, and a vehicle body. The lower front of the vehicle body is equipped with a snowplow, at least two ice breaking turntables are arranged side by side on the lower front surface of the vehicle body, at least two spiral ice scrapers are arranged side by side on the lower surface of the vehicle chassis, and at least two sweeping turntables are arranged side by side at the rear end of the lower surface of the vehicle chassis. This patent uses spiral ice scrapers that rotate along the horizontal plane to break up the ice surface of the road, which is suitable for breaking ice on flat roads. However, this patent does not have a collection device and cannot clean up the broken ice in a timely manner. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] An airport road surface ice-breaking system includes a vehicle chassis, an ice-crushing device, a material-dispensing device, and a collection device. The bottom of the vehicle chassis is sequentially equipped with an ice-crushing device for breaking up road ice, a material-dispensing device, and a collection device for collecting the ice fragments. The material-dispensing device includes a connecting frame, a cam roller, a drum, spike I, and spike II. Connecting frames are located on both sides of the bottom of the vehicle chassis, and a drum driven by a drive motor is rotatably connected between the two connecting frames. The drum has a hollow structure, and multiple sets of spike I are spaced circumferentially along the drum body. Each adjacent set of spike I is separated by a... There is a set of spikes II. Each set of spikes I and spikes II consists of multiple spikes spaced apart along the length of the drum. Spikes I and II both movably penetrate the drum wall. Inside the drum, there is a cam roller for extending spikes I and II out of the drum at the lowest point and retracting them into the drum at the highest point. The cam roller body has grooves corresponding to the position of spikes II, so that when spikes II run to the sides of the lowest point of the drum, the extension length is shorter than the extension length of spike I. Both ends of the cam roller have connecting shafts that movably penetrate the drum. The two connecting shafts are respectively fastened to two connecting frames.

[0007] Preferably, the ice-breaking device includes multiple rotating shafts spaced apart along the width direction of the vehicle chassis. The rotating shafts are rotatably connected to the vehicle chassis and driven by a motor. The bottom of the rotating shafts is provided with ice-breaking blades for breaking the ice surface of the road.

[0008] Preferably, the collection device includes a cargo box located on top of the vehicle chassis and a bucket connected to the bottom of the vehicle chassis. The bucket is inclined upward from the front end to the rear end of the vehicle chassis, and the end of the bucket corresponding to the front end of the vehicle chassis is 1-3 mm away from the road surface. The end of the vehicle chassis corresponding to the bucket away from the material feeding device is provided with a conveyor belt I for conveying the crushed ice in the bucket to the cargo box. A collection box is provided at the rear end of the cargo box, and a conveyor belt II is provided above the collection box for receiving the crushed ice on the conveyor belt I.

[0009] Preferably, the inner wall of the roller is provided with guide sleeves at the positions corresponding to spike I and spike II.

[0010] Preferably, one end of the cam roller corresponding to the spikes I and II has a ball head structure.

[0011] Preferably, the cam roller body is provided with partitions on both sides corresponding to spike I and spike II, and the sidewalls of the partitions are provided with oil storage grooves for storing lubricating grease.

[0012] Preferably, each of the spikes I and II has a retaining ring at one end near the cam roller, and springs are fitted onto the rod body of spikes I and II between the retaining ring and the inner wall of the roller.

[0013] Preferably, the shaft of the spike II is provided with a T-shaped thread, and the inner wall of the roller is provided with nuts at the positions corresponding to the spike II for making the spike II move axially and rotate automatically, and the retaining ring is rotatably connected to the spike II.

[0014] Preferably, the tip of the spike II has one or more slots.

[0015] Preferably, a scraper is provided at the highest point of the roller body, and the two ends of the scraper are fixedly connected to two connecting frames respectively, and the scraper is provided with clearance slots at the positions corresponding to the spikes I and II.

[0016] By employing the technical solution described above, the present invention has the following beneficial effects:

[0017] This invention discloses an airport road surface ice-breaking system with a simple structure that can collect ice fragments while breaking up road ice. The feeding device includes spike I and spike II, both of which movably penetrate the wall of a drum, meaning that spike I and spike II can extend and retract radially along the drum. A cam roller is provided inside the drum, and the cam roller body has grooves corresponding to the position of spike II, so that when spike II runs to the lowest point on both sides of the drum, the extension length is shorter than the extension length of spike I. During the process of spike I pushing the ice fragments towards the collecting device, spike II extends out of the drum, pierces the ice fragments, and further breaks up the ice fragments broken by the ice-breaking device, preventing the ice fragments from clogging the collecting device. At the same time, spike I and spike II extend and retract radially along the drum while rotating circumferentially along the cam roller, avoiding the rotation of ice fragments and ensuring that the feeding function is always good.

[0027] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this application for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation.

[0028] Example 1, in conjunction with Appendix Figures 1-4 An airport road surface ice-breaking system includes a vehicle chassis 1, an ice-crushing device 2, a material-dispensing device 3, and a collection device 4. The bottom of the vehicle chassis 1 is equipped with the ice-crushing device 2, the material-dispensing device 3, and the collection device 4 for collecting the ice fragments, arranged sequentially from front to back. That is, when the vehicle chassis 1 travels along an icy road, the ice-crushing device 2 crushes the ice surface, and then the material-dispensing device 3 dispenses the ice fragments to the collection device 4 for easy collection.

[0029] The feeding device 3 includes a connecting frame 3-1, a cam roller 3-2, a roller 3-3, spikes I 3-4 and spikes II 3-5. The connecting frames 3-1 are provided on both sides of the bottom of the vehicle chassis 1. A roller 3-3 driven by a drive motor is rotatably connected between the two connecting frames 3-1. The roller 3-3 has a hollow structure. Multiple sets of spikes I 3-4 are arranged circumferentially along the cylinder body of the roller 3-3. A set of spikes II 3-5 is provided between two adjacent sets of spikes I 3-4. Each set of spikes I 3-4 and spikes II 3-5 consists of multiple spikes arranged at intervals along the length of the roller 3-3. Spikes I 3-4 and spikes II 3-5 can move through the cylinder wall of the roller 3-3, that is, spikes I 3-4 and spikes II 3-5 can extend and retract radially along the roller 3-3. A set of spikes I 3-4 and an adjacent set of spikes II 3-5 are arranged alternately.

[0030] The drum 3-3 is equipped with a cam roller 3-2 that allows spikes I 3-4 and II 3-5 to extend out of the drum 3-3 at its lowest point and retract into the drum 3-3 at its highest point. The cam roller 3-2 has grooves 3-7 on its body corresponding to the position of spike II 3-5, ensuring that spike II 3-5 extends for a shorter length than spike I 3-4 when it reaches the sides of the lowest point of the drum 3-3. Both ends of the cam roller 3-2 are equipped with connecting shafts 3-6 that movably penetrate the drum 3-3. The two connecting shafts 3-6 are respectively connected to two… Each connecting frame 3-1 is fastened accordingly. During operation, the roller 3-3, driven by the drive motor, rotates. The roller 3-3 causes spikes I 3-4 and II 3-5 to rotate axially along the cam roller 3-2. Simultaneously, spikes I 3-4 and II 3-5 extend and retract radially along the roller 3-3 under the action of the cam roller 3-2. When spikes I 3-4 and II 3-5 reach the top of the cam roller 3-2, they retract into the roller 3-3, preventing them from carrying ice fragments. As the roller rotates, spikes I 3-4 and II 3-5 gradually extend out of the roller 3-3. As spike I 3-4 moves to the sides and bottom of the cam roller 3-2, it is constantly pushed out of the roller 3-3 by the cam roller 3-2. Spike II 3-5 rotates along the groove 3-7. As spike II 3-5 moves to the sides and top of the cam roller 3-2, it retracts into the roller 3-3. It gradually extends out of the roller 3-3 as it moves from one side of the cam roller 3-2 to the bottom of the cam roller 3-2, and then gradually retracts. As spike I 3-4 pushes the ice crushed material toward the collection device 4, spike II 3-5 extends out of roller 3-3, piercing the ice crushed material and further breaking up the ice crushed by ice crushing device 2, preventing the ice crushed material from clogging the collection device 4. At the same time, spike I 3-4 and spike II 3-5 extend and retract radially along roller 3-3 while rotating circumferentially along cam roller 3-2, preventing the ice crushed material from being carried around and ensuring that it always has a good material pushing function. Spike I 3-4 and spike II 3-5 never come into contact with the road surface, which can avoid damaging the airport road surface.

[0031] Example 2, in conjunction with Appendix Figures 1-6An airport road surface ice-breaking system differs from Embodiment 1 in that, based on Embodiment 1, the ice-breaking device 2 includes multiple rotating shafts 2-1 spaced apart along the width direction of the vehicle chassis 1. The rotating shafts 2-1 are rotatably connected to the vehicle chassis 1 and driven by a motor. The bottom of the rotating shafts 2-1 is provided with ice-breaking blades 2-2 for breaking the road ice surface. Multiple ice-breaking blades 2-2 are arranged circumferentially along the shaft of the rotating shafts 2-1, and a gap of 1-3mm is left between the blades of the ice-breaking blades 2-2 and the road surface. That is, the rotating shafts 2-1 are driven by the motor to rotate, and the rotating shafts 2-1 drive the ice-breaking blades 2-2 to rotate. When the ice-breaking blades 2-2 rotate, they break the ice surface of the road. The ice-breaking blades 2-2 rotate horizontally, resulting in high ice-breaking efficiency and no damage to the airport road surface, thus reducing the later maintenance cost of the airport road surface.

[0032] The collecting device 4 includes a cargo box 5 located on top of the vehicle chassis 1, and a bucket 4-1 connected to the bottom of the vehicle chassis 1. Both ends of the bucket 4-1 are open, and the bucket 4-1 is inclined upwards from the front to the rear of the vehicle chassis 1. The end of the bucket 4-1 corresponding to the front of the vehicle chassis 1 is 1-3 mm away from the road surface. A conveyor belt I 4-4 is provided at the end of the vehicle chassis 1 opposite to the material feeding device 3 to transport the crushed ice in the bucket 4-1 to the cargo box 5. The rear end of the compartment 5 is equipped with a collection box 4-2. Above the collection box 4-2 is a conveyor belt II 4-3 for receiving ice crushed from the conveyor belt I 4-4. As the vehicle chassis 1 moves and the material feeding device 3 rotates, the road surface ice crushed is fed into the bucket 4-1. As the ice crushed accumulates in the bucket 4-1, it can gradually move backward and fall onto the surface of the conveyor belt I 4-4. The conveyor belt I 4-4 lifts the ice crushed to the surface of the conveyor belt II 4-3 and finally delivers it into the collection box 4-2.

[0033] Example 3, in conjunction with Appendix Figures 1-8 An airport pavement ice-breaking system, based on embodiment 1 or 2, includes guide sleeves 3-8 on the inner wall of the roller 3-3 at positions corresponding to spikes I 3-4 and II 3-5. The guide sleeves 3-8 effectively improve the stability of spikes I 3-4 and II 3-5 when they extend and retract radially along the roller 3-3. One end of spikes I 3-4 and II 3-5 corresponding to the cam roller 3-2 has a ball-head structure, which effectively reduces the friction between spikes I 3-4 and II 3-5 and the cam roller 3-2. To ensure the smoothness of the rotation of spike I 3-4 and spike II 3-5 along the circumferential direction of cam roller 3-2; the cam roller 3-2 is provided with partitions 3-9 on both sides of the roller body corresponding to spike I 3-4 and spike II 3-5. The side wall of partition 3-9 is provided with an oil storage groove for storing grease. The partition 3-9 can further improve the stability of spike I 3-4 and spike II 3-5 during operation, and can store grease in the oil storage groove, further reducing the friction between spike I 3-4, spike II 3-5 and cam roller 3-2.

[0034] Example 4, in conjunction with Appendix Figures 1-8 An airport road surface ice-breaking system, based on any of the embodiments 1 to 3, wherein each of the spikes I 3-4 and II 3-5 is provided with a retaining ring 3-10 at one end near the cam roller 3-2, and a spring 3-11 is sleeved on the rod between the retaining ring 3-10 and the inner wall of the roller 3-3 corresponding to the spikes I 3-4 and II 3-5. That is, the spikes I 3-4 and II 3-5 can automatically retract under the action of the spring 3-11 during the circumferential rotation along the cam roller 3-2, thereby getting rid of ice fragments and avoiding the spikes I 3-4 and II 3-5 being unable to retract automatically due to ice fragments sticking to or being stuck on the rod.

[0035] Example 5, in conjunction with Appendix Figures 1-8 An airport road surface ice-breaking system, based on embodiment 4, wherein the spike II 3-5 rod body is provided with a T-shaped thread, and the inner wall of the roller 3-3 is provided with nuts at positions corresponding to the spike II 3-5 for the spike II 3-5 to move axially and rotate automatically, and the retaining ring 3-10 is rotatably connected to the spike II 3-5, that is, the spike II 3-5 and the nut are threadedly engaged, and the spike II 3-5 can rotate while extending and retracting using the principle of the lead screw nut, thereby better breaking and removing ice; the tip of the spike II 3-5 is provided with one or more slots, so that the spike II 3-5 can better break ice while rotating.

[0036] Example 6, in conjunction with Appendix Figures 1-8 An airport road surface ice-breaking system, based on any one of the embodiments 1 to 5, wherein the highest point of the roller 3-3 is provided with a scraper 3-12, and the two ends of the scraper 3-12 are respectively fixedly connected to two connecting frames 3-1, and the scraper 3-12 is provided with clearance slots at the positions corresponding to the spikes I 3-4 and II 3-5. The scraper 3-12 can clean the ice fragments adhering to the roller 3-3 while the roller 3-3 rotates, and the clearance slots can avoid interference between the scraper 3-12 and the spikes I 3-4 and II 3-5.

[0037] The parts of this invention not described in detail are prior art. It will be apparent to those skilled in the art that this invention is not limited to the details of the above exemplary embodiments, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to encompass all changes falling within the meaning and scope of equivalents within this invention.
