Description

Technical Field

[0001] This utility model belongs to the technical field of de-icing equipment, specifically relating to a roller-cage planer-type road de-icing machine. Background Technology

[0002] Winter road icing poses a serious threat to traffic safety. Currently, there are several de-icing methods, including chemical de-icing agents, mechanical impact de-icing, and single-roller de-icing machines. However, chemical de-icing agents can cause corrosion to bridge steel bars due to chlorides, pollute soil and water sources, and are significantly less effective at ice temperatures below -15°C. Vibratory ice breakers can damage asphalt pavement due to impact force, and they don't completely break up the ice at the junction with the pavement layer, leaving a thin layer of ice that can lead to secondary icing. Traditional roller-type ice breakers have a simple layout, and the ice-breaking process easily generates periodic impact loads, causing equipment vibration and blade chipping.

[0003] Therefore, this application proposes a roller-cage shovel type road de-icing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing de-icing methods, such as soil pollution, steel reinforcement corrosion, road surface damage, and damage to the equipment itself. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention. It is not intended to identify key or essential parts of the invention, nor is it intended to limit the scope of the invention.

[0005] The technical solution of this utility model:

[0006] A roller-cage shovel type road de-icing machine includes a connecting arm and a first roller-cage ice-breaking wheel. The first roller-cage ice-breaking wheel is connected to a vehicle through the connecting arm. The first roller-cage ice-breaking wheel includes partitions, a first planer blade, and a second planer blade. Multiple partitions are arranged in a transverse array and connected by a spline roller shaft. The two ends of the spline roller shaft are rotatably connected to the connecting arm. There are gaps between adjacent partitions. The first planer blade and the second planer blade are alternately arranged in the gaps. The first planer blade and the second planer blade are respectively installed on both sides of the partitions. The cutting ends of the first planer blade and the second planer blade are both chamfered, and the chamfer angle ranges from 35° to 40°.

[0007] Furthermore, the partition plate is machined with multiple shaft holes in the circumferential direction, and a planer shaft is provided in each shaft hole. The first planer blade and the second planer blade are mounted on the partition plate through the planer shaft.

[0008] Furthermore, a protective cover is installed on the connecting arm, and the protective cover is fastened over the partition.

[0009] Furthermore, it also includes a second roller ice-breaking wheel, which includes partitions and third planer blades. Multiple partitions are arranged in a transverse array and connected by a spline roller shaft. The two ends of the spline roller shaft are rotatably connected to the connecting support arm. There are gaps between adjacent partitions, and multiple third planer blades are arranged in the gaps. The third planer blades are mounted on the partitions.

[0010] Furthermore, the partition plate has multiple shaft holes machined in the circumferential direction, and the third planer blade is mounted on the partition plate through the mating connection between the planer shaft and the shaft holes. The tip of the third planer blade is chamfered, with the chamfer angle ranging from 35° to 40°, and the blade body of the third planer blade is machined with a weight reduction groove.

[0011] Furthermore, the connecting arm includes a straight arm and an inclined arm. One end of the straight arm is integrally formed with the inclined arm, and the other end of the straight arm is connected to the engineering vehicle. The second roller icebreaker is installed on the straight arm, and the first roller icebreaker is installed on the inclined arm. The diameter ratio of the first roller icebreaker to the second roller icebreaker is 2:1.

[0012] Furthermore, the first roller ice-breaking wheel is mounted on a trolley via a connecting arm. The trolley is equipped with a motor, and the actuator end of the motor is connected to a small pulley. The small pulley is connected to a large pulley via a transmission belt. The large pulley is connected to the splined roller shaft of the first roller ice-breaking wheel. The bottom of the trolley is equipped with wheels and support legs.

[0013] This utility model has the following beneficial effects:

[0014] 1. The present invention relates to a roller-cage shovel type road de-icing machine, wherein the partition plates adopt an alternating blade layout on both sides, and the continuous cutting and shoveling replaces impact crushing, avoiding the creation of hidden marks on the asphalt surface. The chamfered design of the first and second shovel blades reduces cutting resistance, balances cutting ability and anti-chipping performance, and the gap between adjacent partition plates allows the immediate discharge of ice fragments, avoiding blockage in the roller-cage ice-breaking wheel.

[0015] 2. The present invention provides a roller cage shovel type road de-icing machine with a double roller cage design, which can be connected to an engineering vehicle. The large-diameter first roller cage ice-breaking wheel on the inclined arm realizes the pre-cracking and initial crushing of the ice layer, and the small-diameter design of the second roller cage ice-breaking wheel realizes the concentrated crushing, forming a stepped de-icing. The diameter ratio of the double roller cages is 2:1 to optimize the torque distribution. After the first roller cage ice-breaking wheel pre-cracks, the load on the second roller cage ice-breaking wheel is reduced.

[0016] 3. In the present invention, a roller-cage planer-type road de-icing machine has a weight-reducing groove processed on the third planer blade of the second roller ice-breaking wheel. The rotational inertia is reduced by the weight-reducing groove, thereby reducing the impact force on the planer blade itself and improving the service life of the planer blade.

However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0034] Example 1, combined with Figures 1-5 , Figures 8-11 This embodiment describes a roller-cage shovel type road de-icing machine, including a connecting arm 1 and a first roller-cage ice-breaking wheel 2. The first roller-cage ice-breaking wheel 2 is connected to a vehicle through the connecting arm 1. The first roller-cage ice-breaking wheel 2 includes partitions 21, a first planer blade 22, and a second planer blade 23. Multiple partitions 21 are arranged in a transverse array and connected by a spline roller shaft 4. The two ends of the spline roller shaft 4 are rotatably connected to the connecting arm 1. There are gaps between adjacent partitions 21, and the first planer blade 22 and the second planer blade 23 are alternately arranged in the gaps. The first planer blade 22 and the second planer blade 23 are respectively installed on both sides of the partitions 21. The cutting ends of the first planer blade 22 and the second planer blade 23 are both chamfered, and the chamfer angle ranges from 35° to 40°.

[0035] As attached Figure 2 As shown, the splined roller shaft 4 of the first roller icebreaker 2 is connected in series with 21 partitions 21. The partitions 21 are circular in shape, made of 65Mn, and hardened to HRC55. The adjacent partitions are spaced 50mm apart to form a gap. The first planer blade 22 has a blade length of 120mm, a blade body thickness of 8mm, and a blade tip chamfer of 38°. The second planer blade 23 has the same parameters as the first planer blade 22. The first planer blade 22 and the second planer blade 23 are fixed by a φ16mm planer shaft 24 passing through the shaft hole 25 of the partition 21. The load-bearing capacity of a single partition 21 reaches 2.5t. During operation, the alternately arranged first planer blade 22 and second planer blade 23 alternately cut into the ice layer to eliminate periodic impact vibration.

[0036] As attached Figures 3-5As shown, the three first planer blades 22 are installed on one side of the partition 21 in an odd-numbered arrangement, and the three second planer blades 23 are installed on the other side of the partition 21 in an even-numbered arrangement.

[0037] Example 2, combined with Figure 6 , Figure 7 and Figure 12 This embodiment describes a roller-cage shovel type road de-icing machine that employs a double-roller ice-breaking wheel design. The connecting arm 1 comprises two parts: a straight arm 11 and an inclined arm 12. One end of the straight arm 11 is integrally formed with the inclined arm 12, and the other end of the straight arm 11 is connected to an engineering vehicle, as shown in the attached diagram. Figure 12 As shown. The first roller icebreaker 2 has a diameter of 600mm and is mounted on the inclined arm 12. The second roller icebreaker 3 has a diameter of 300mm and is mounted on the straight arm 11. Each partition 21 of the second roller icebreaker 3 is equipped with a third planer blade 31. Each third planer blade 31 is mounted in the shaft hole 25 on the partition 21 through the planer shaft 24. The cutting edge of the third planer blade 31 has a chamfer of 40° and the blade body has a weight reduction groove 32, which reduces the weight by 30% compared to the blade body without groove. Six third planer blades 31 are evenly distributed around the circumference of each partition 21.

[0038] During operation, the first roller icebreaker 2 at the front provides the advantage of linear velocity, with a speed of 1.2 m / s. The second roller icebreaker 3 at the rear increases the torque and has a rotation speed that is twice as high. After the ice layer is pre-cracked by the alternating blades of the first roller icebreaker 2, the second roller icebreaker 3 at the rear focuses on breaking the deep ice body after pre-cracking.

[0039] Example 3, combined with Figures 13-14 This embodiment describes a roller-cage shovel type road de-icing machine. The first roller-cage ice-breaking wheel 2 is mounted on a trolley 7 via a connecting arm 1. It is suitable for narrow locations such as sidewalks and intersections / lighthouses. A motor 5 on the trolley 7 drives the first roller-cage ice-breaking wheel 2 to rotate. Wheels 6 and support legs 9 below the trolley 7 control the trolley's forward and backward movement and fix it in place. The motor 5 drives a large pulley 73 connected to a splined roller shaft 4 to rotate via a small pulley 72 and a transmission belt 71, thereby driving the partition 21 to rotate. When the motor 5 rotates, the first and second shovel blades 22 and 23, evenly distributed on the partition 21, rotate counterclockwise. The first and second shovel blades 22 and 23 scoop up the ice layer from bottom to top. This method has a good breaking effect on thin ice layers and solid ice, avoiding incomplete ice breaking and secondary icing.

[0040] When a planer cuts through ice, it can swing at a certain angle around its axis. If it touches the road surface, it can bounce off, avoiding hard contact with the road surface and thus preventing damage or breakage of the planer.

[0041] The experimental prototype uses a gasoline engine to drive a single set of rollers, which in turn drives the wheels. The roller width is 800mm, the rotation speed is 10r / s, the trolley speed is about 1.2km / h, the planer blade length is 120mm, and the planing depth is set to 30mm.

[0042] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
