DETAILED DESCRIPTION

[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0035] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.

[0036] In a first aspect, the present application provides a road and bridge safety maintenance and deicing device, such as Figure 1-Figure 6 As shown, the deicing device includes: a frame 100, a crushing roller 200 and a crushing mechanism 300. The crushing roller 200 is rotatably connected to the frame 100, and the crushing mechanism 300 includes a guide plate 310 arranged on the frame 100 and at least one crushing pressing plate 320 arranged on the upper side of the guide plate 310, the guide plate 310 is arranged to be tilted downward toward one side of the crushing roller 200, and the side of the guide plate 310 facing away from the crushing roller 200 is spaced from the frame 100 to form a discharge port; the crushing pressing plate 320 is slidably arranged on the frame 100 so as to be able to move toward and away from the guide plate 310.

[0037] The frame 100 provides stable support for the crushing roller 200 and the crushing mechanism 300 to ensure that the device maintains balance and operates efficiently during the deicing process. The frame 100 can be made of high-strength steel to enhance its bearing capacity. The shape of the frame 100 can be adaptively designed according to the installation requirements of the crushing roller 200 and the crushing mechanism 300.

[0038] For example Figure 2 and Figure 3 As shown, the frame 100 may include a supporting frame 110, a first cover shell 120 and a second cover shell 130. The supporting tube body is composed of a plurality of beam structures spliced ​​together to form a solid frame structure. The first cover shell 120 and the second cover shell 130 are both connected to the supporting frame 110, respectively covering the crushing roller 200 and the crushing mechanism 300 to provide protection.

[0039] The crushing roller 200 may include a roller body 210 and a plurality of crushing teeth 220 arranged at intervals on the surface of the roller body 210. The roller body 210 is in a horizontally arranged cylindrical shape, and a plurality of crushing teeth 220 are evenly arranged on the outer peripheral surface of the roller body 210. The crushing roller 200 can roll on the ice and snow layer, and utilize the weight of the crushing roller 200 and the cutting effect of the crushing teeth 220 to crush the ice and snow layer into fragments of a certain volume.

[0040] The guide plate 310 is a plate structure provided on the main frame, and is used to guide the broken pieces after being crushed by the crushing roller 200 to the bottom of the crushing plate 320. The guide plate 310 and the crushing roller 200 are arranged in the horizontal direction, and the guide plate 310 should be located behind the advancing direction of the crushing roller 200, so as to guide the crushed pieces to the bottom of the crushing plate 320 during the movement of the deicing device. The guide plate 310 may include a first inclined section 310a, a second inclined section 310b and a third inclined section 310c which are arranged in sequence, wherein the first inclined section 310a has a larger inclination angle, and one end of the first inclined section 310a close to the crushing roller 200 is flush with the lowest point of the crushing roller 200 so as to be able to scoop up the crushed fragments; the inclination angle of the second inclined section 310b is smaller than that of the first inclined section 310a, and is used to make the fragments smoothly transition to the bottom of the crushing plate 320, stably withstand the pressure of the crushing plate 320, and improve the crushing effect; the inclination direction of the third inclined section 310c is opposite to that of the first inclined section 310a and the second inclined section 310b, and is spaced apart from a part of the frame 100 to form a discharge port, so that the small particles crushed by the crushing plate 320 can be discharged smoothly to avoid blockage.

[0041] During the process of moving, the deicing device can guide the crushed pieces to the second inclined section 310b through the first inclined section 310a toward one end of the crushing roller 200, and make the crushing plate 320 located on the second inclined section 310b further crush the pieces. As the deicing device continues to move forward, the crushed particles slide through the third inclined section 310c and are discharged from the crushing mechanism 300. In addition, the bottoms of the first inclined section 310a, the second inclined section 310b and the third inclined section 310c are also connected to the reinforcing ribs to further improve the overall strength and stability of the guide plate 310, so that it is not easy to deform or damage during the deicing operation, thereby extending the service life of the equipment.

[0042] The crushing plate 320 may be located on the upper side of the second inclined section 310b and slidably connected to the support frame 110110 of the frame 100 through structures such as guide rails. The sliding direction of the crushing plate 320 is the vertical direction, so that the crushing plate 320 can move toward and away from the guide plate 310. The shape of the crushing plate 320 can match the shape of the second inclined section 310b of the guide plate 310. For example, the shape of the crushing plate 320 is rectangular, and the lower surface of the crushing plate 320 is parallel to the upper surface of the second inclined section 310b, so as to better apply pressure to the fragments on the second inclined section 310b. The number of crushing plates 320 can be adapted based on the length of the second inclined section 310b, so that one or more crushing plates 320 can completely cover the entire second inclined section 310b. For example, the number of crushing plates 320 is multiple and is arranged at intervals along the extension direction of the second inclined section 310b.

[0043] The deicing device provided in the embodiment of the present application can be connected to the front or rear end of a vehicle, and the deicing device can be pushed or pulled by the vehicle to move on the road, or tires and engines can be installed on the deicing device so that it can move on the road by itself. During the movement, the crushing roller 200 will roll on the road and use its cutting effect to crush the ice and snow layer. Under the guidance of the guide plate 310, the crushed fragments are gradually crushed into smaller particles by the crushing plate 320 and finally discharged through the discharge port, thereby crushing and crushing the ice and snow layer into smaller block particles, which is convenient for subsequent cleaning and transportation by staff and is not prone to secondary icing.

[0044] In some embodiments, a surface of the crushing plate 320 facing the guide plate 310 and / or a surface of the guide plate 310 facing the crushing plate 320 is provided with a plurality of protrusions arranged at intervals.

[0045] Specifically, a protrusion may be provided on the lower surface of the crushing plate 320 or the upper surface of the second inclined section 310b of the guide plate 310, so that the lower surface of the crushing plate 320 or the upper surface of the second inclined section 310b are both uneven structures, thereby improving the crushing effect on the fragments and further reducing the particle size of the fragments. The shape of the protrusion may be arbitrary, for example, the protrusion may be in a hemispherical structure, which can not only improve the crushing effect on the fragments, but also not easily block the fragments, so that the fragments can move smoothly.

[0046] It is understandable that the protrusions may be provided only on the lower surface of the crushing plate 320, or only on the upper surface of the second inclined section 310b; or the protrusions may be provided on both the crushing plate 320 and the second inclined section 310b at the same time, so that the protrusions on both sides cooperate with each other to form a more efficient crushing effect.

[0047] For example, Figure 4 As shown, the plurality of protrusions include a first protrusion 3201 disposed on the surface of the crushing plate 320 facing the guide plate 310 and a second protrusion 3101 disposed on the surface of the guide plate 310 facing the crushing plate 320, and the first protrusion 3201 and the second protrusion 3101 are arranged alternately. When the crushing plate 320 moves toward the guide plate 310, the first protrusion 3201 can be embedded in the gap of the adjacent second protrusion 3101, and the second protrusion 3101 can be embedded in the gap of the adjacent first protrusion 3201, forming a staggered bite structure, thereby significantly enhancing the crushing force and efficiency, and ensuring that the fragments are fully refined during the movement.

[0048] In some embodiments, two baffles 311 are further disposed on the upper surface of the guide plate 310 . The two baffles 311 are arranged at intervals along the axial direction of the crushing roller 200 , and the height of the baffles 311 is higher than the crushing plate 320 .

[0049] Specifically, the baffle 311 is a side protection structure vertically arranged on the upper surface of the guide plate 310. The axial direction of the crushing roller 200 corresponds to the width direction of the guide plate 310, that is, the two baffles 311 are respectively located at the two ends of the width direction of the guide plate 310 to prevent the fragments on the guide plate 310 from splashing during the crushing process, or directly sliding off the two sides of the guide plate 310, so as to ensure that the fragments are always crushed in the pressure area under the crushing plate 320. The height of the baffle 311 should be higher than the maximum stroke of the crushing plate 320 to ensure that the fragments will not pass over the baffle 311 during the crushing process, and can also effectively protect the crushing plate 320 and the driving assembly 350. In addition, the side of the baffle 311 facing the crushing roller 200 can also be provided with a groove matching the surface shape of the crushing roller 200 to avoid interfering with the rotation of the crushing roller 200.

[0050] like Figure 3 and Figure 5 As shown, in some embodiments, the crushing mechanism 300 further includes a limit plate 330 disposed above the guide plate 310, the limit plate 330 is connected between the two baffles 311, and is located on the side of the guide plate 310 close to the crushing roller 200, and the height of the limit plate 330 is less than or equal to the highest point of the crushing plate 320 during movement. This guides the broken pieces to enter the crushing area more smoothly, avoids the broken pieces from accumulating near the first inclined section 310a and moving to the upper side of the crushing plate 320, and ensures the stable operation of the crushing plate 320.

[0051] In some embodiments, the crushing mechanism 300 also includes at least two lifting rods 340 , which are parallel to each other and arranged at intervals along the extension direction of the guide plate 310 , and one end of the lifting rod 340 is rotatably connected to the frame 100 , and the other end is rotatably connected to the guide plate 310 .

[0052] Specifically, the lifting rod 340 is a long strip structure, the bottom end of which is rotatably connected to the baffle 311, and the top end is connected to the support frame 110 of the frame 100. At least two lifting rods 340 can be arranged on each baffle 311, so that the guide plate 310 can be supported below the frame 100 by using multiple lifting rods 340. The multiple lifting rods 340 are parallel to each other, and the overall lifting and lowering of the guide plate 310 can be achieved by controlling the swing of the lifting rods 340, and the height of the crushing area can be adjusted. The guide plate 310 can also be raised after the deicing operation is completed to avoid hard contact between the guide plate 310 and the road surface during non-operation.

[0053] In actual use, the first driver 341 may be connected to the lifting rod 340 to control the swing of the lifting rod 340. The first driver 341 may be a hydraulic cylinder, an electric push rod or other driving device, which can automatically control the lifting action of the guide plate 310 on the one hand, and maintain the position of the guide plate 310 on the other hand to avoid position shaking during operation.

[0054] In actual use, the pulverizing mechanism 300 should also include a driving assembly 350, and the pulverizing plate 320 is connected to the driving assembly 350, so that the driving assembly 350 can be used to control the up and down sliding of the pulverizing plate 320. When there are multiple pulverizing plates 320, the multiple pulverizing plates 320 can be connected to the same driving assembly 350, so that the multiple pulverizing plates 320 can be driven to slide at the same time by one driving assembly 350. The driving assembly 350 can be electrically or hydraulically driven.

[0055] In some embodiments, when multiple crushing plates 320 are connected to a driving assembly 350, the driving assembly 350 may include a crankshaft 351 and multiple connecting rods 352. The crankshaft 351 is rotatably connected to the frame 100 and includes multiple eccentric components that are arranged at intervals and connected in series. The number of eccentric components is the same as the number of crushing plates 320 and corresponds one to one. The number of connecting rods 352 is the same as the number of eccentric components. One end of the connecting rod 352 is rotatably connected to a corresponding eccentric component, and the other end is rotatably connected to a corresponding crushing plate 320.

[0056] Specifically, Figure 6 As shown, the crankshaft 351 is composed of a plurality of eccentric components connected in series, wherein the eccentric components include an eccentric shaft 351a and two eccentric disks 351b connected to both ends of the eccentric shaft 351a, and two adjacent eccentric components are connected to each other through a connecting shaft 351c, the axis of the eccentric shaft 351a is parallel to and spaced from the axis of the connecting shaft 351c, and the two adjacent eccentric shafts 351a are arranged in a staggered manner. A crankcase 140 is provided on the frame 100, and the crankshaft 351 is rotatably connected to the crankcase 140, and the rotation axis of the crankshaft 351 coincides with the axis of the connecting shaft 351c, and during the rotation of the crankshaft 351, the eccentric shaft 351a also rotates around the axis of the connecting shaft 351c.

[0057] The connecting rod 352 is arranged between the eccentric shaft 351a and the corresponding crushing plate 320. One end of the connecting rod 352 is sleeved on the eccentric shaft 351a and is rotatably connected to the eccentric shaft 351a. A connecting piece 321 is provided on the upper surface of the crushing plate 320, and a hinge shaft 322 is provided on the connecting piece 321. The other end of the connecting rod 352 is rotatably connected to the hinge shaft 322. Therefore, in the process of the eccentric shaft 351a rotating around the connecting shaft 351c, the connecting rod 352 drives the crushing plate 320 to reciprocate up and down, thereby achieving the purpose of crushing the fragments on the guide plate 310.

[0058] Among the multiple crushing platens 320, two adjacent crushing platens 320 are connected to different eccentric shafts 351a, so that when one of the plates moves downward, the other platen moves upward, forming an alternating crushing effect, avoiding the accumulation of fragments on the guide plate 310, ensuring that the fragments are evenly compressed, and improving the crushing efficiency.

[0059] It should be noted that the driving assembly 350 should also include a second driver 353 installed on the frame 100. The second driver 353 can be an engine, a motor or other power source. The driver is connected to the crankshaft 351 through a transmission structure to drive the crankshaft 351 to rotate, thereby realizing the alternating crushing action of the multiple crushing plates 320. The transmission structure can be a belt drive, a gear drive or a chain drive to ensure stable and efficient power transmission.

[0060] On the other hand, an embodiment of the present application also provides a road and bridge safety maintenance and deicing equipment, including a driving vehicle and the road and bridge safety maintenance and deicing device provided in the embodiment of the first aspect, wherein the deicing device is installed on the driving vehicle.

[0061] Specifically, the driving vehicle is a vehicle structure capable of traveling on a road surface. The deicing device can be connected to the frame 100 with the chassis of the driving vehicle so that the driving vehicle can drive the deicing device to move on the road surface to achieve deicing operations.

[0062] Among them, the de-icing device can be installed on the front side of the driving vehicle, so that the driving vehicle pushes the de-icing device forward. At this time, the crushing roller 200 should be located on the side of the crushing mechanism 300 away from the driving vehicle; the de-icing device can also be installed on the rear side of the driving vehicle and be towed forward by the driving vehicle. At this time, the crushing roller 200 should be located on the side of the crushing mechanism 300 close to the driving vehicle, so that the crushed fragments can enter the crushing mechanism 300 for secondary crushing.

[0063] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and its core idea of ​​the present application. At the same time, changes or deformations made by those skilled in the art based on the ideas of the present application, the specific implementation methods and the scope of application of the present application, all belong to the scope of protection of the present application. In summary, the content of this specification should not be construed as a limitation on the present application.
