Description

Technical Field

[0001] The utility model relates to the field of crawlers for engineering vehicles, and specifically relates to a crawler for engineering vehicles that reduces road surface impact. Background Technique

[0002] Engineering vehicles are the main force in a construction project. Due to their appearance, the progress of the construction project has doubled, greatly reducing the manpower. Engineering vehicles are generally driven by crawlers. Due to their large power, high fuel consumption, and heavy load, when the crawlers move, they will not only damage the asphalt or concrete road surface, but also easily cause damage to the crawlers. Therefore, in view of the above deficiencies, a crawler for engineering vehicles that reduces road surface impact is proposed.

[0003] Engineering vehicles are the main force in a construction project. Due to their appearance, the progress of the construction project has doubled, greatly reducing the manpower. Engineering vehicles are generally driven by crawlers, mainly to reduce the pressure and wear on the road surface. Traditional engineering vehicles using rubber tires will concentrate the pressure on smaller contact points during driving, easily leading to road surface compaction, damage, and increased wear. The crawler technology can evenly distribute the vehicle's weight over a larger contact area by using continuous rubber crawlers, effectively reducing the impact and pressure on the road surface and reducing the frequency of road surface damage.

[0004] Due to their large power, high fuel consumption, and heavy load, when the crawlers move, they will not only damage the asphalt or concrete road surface, reducing the service life of the road surface and increasing maintenance costs, but also easily cause damage to the crawlers. Therefore, in view of the above deficiencies, a crawler for engineering vehicles that reduces road surface impact is proposed. For this reason, we propose a crawler for engineering vehicles that reduces road surface impact. Content of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4A crawler track for an engineering vehicle for reducing road impact comprises a crawler block 1, a connecting rod 2, a crawler block 2 3, a track shoe 4 and a rubber buffer plate 8. The crawler block 1 and the crawler block 2 3 have the same structure. The crawler block 1 is an axisymmetric structure as a whole. The crawler block 1 is provided with a connecting block 2 6 and two connecting blocks 5 at one end corresponding to the crawler block 2 3, and the two connecting blocks 5 are located at both ends of the connecting block 2 6. The crawler block 2 3 is provided with a connecting block 3 7 matched with the notch between the connecting block 5 and the connecting block 2 6 at one end corresponding to the crawler block 1, and the connecting block 1 5, the connecting block 2 6 and the connecting block 3 7 are all provided with connecting holes 20. The crawler block 1 is provided with a connecting rod 2 matched with the connecting hole 20 between the connecting rods 2. The crawler block 1 is composed of a crawler shoe 4 and a rubber buffer plate 8 matched and connected.

[0026] Furthermore, a protrusion 12 is provided on the outer end of the track shoe 4 that is away from the rubber buffer plate 8 through the axisymmetric line, and a matching groove 13 that cooperates with the driving part of the engineering vehicle is provided in the middle part of the protrusion 12. Two water retaining blocks 10 are axially symmetrically distributed on both sides of the protrusion 12 at the outer end of the track shoe 4 that is away from the rubber buffer plate 8. The water retaining blocks 10 are raised inwardly to prevent water stains on the road surface from splashing into the middle part of the track block and the air vents 14.

[0027] Furthermore, two air holes 14 are axially symmetrically distributed at one end of the track shoe 4 corresponding to the rubber buffer plate 8. The air holes 14 pass through the track shoe 4. The end of the air holes 14 facing away from the rubber buffer plate 8 is connected to an end surface of the water retaining block 10 relative to the protrusion 12, and the end of the air holes 14 facing away from the rubber buffer plate 8 is provided with a protective net 11 adapted to be connected thereto. The protective net 11 can prevent some particulate impurities from entering the interior of the rubber buffer plate 8, resulting in unstable sealing.

[0028] Furthermore, two sealing holes 19 concentric with the air vent 14 are provided at one end of the rubber buffer plate 8 corresponding to the track shoe 4, a cavity is provided inside the rubber buffer plate 8, a sealing member 16 concentric with the sealing hole 19 and a plurality of rebound members 15 are provided inside the rubber buffer plate 8, and a group of anti-sliding blocks 9 are equidistantly distributed at one end of the rubber buffer plate 8 away from the track shoe 4.

[0029] Furthermore, the seal 16 is composed of a spring 17 and a rubber block 18. The end of the seal 16 facing away from the sealing hole 19 is the spring 17. The end of the spring 17 facing away from the rubber block 18 is connected to the bottom of the rubber buffer plate 8. The end of the spring 17 corresponding to the sealing hole 19 is connected to the rubber block 18. The rubber block 18 is a circular boss with a large end face at the end close to the spring 17. The rubber block 18 can effectively perform interference fit with the sealing hole 19. Combined with the huge weight of the engineering vehicle itself, its sealing performance is greatly improved.

[0030] Furthermore, the resilient member 15 is a Z-shaped plate, and the two flat surfaces of the resilient member 15 are fitted and connected to the two large end faces inside the rubber buffer plate 8.

[0031] Working principle: Assemble the crawler blocks for the construction vehicle correctly according to the illustration. The crawler block 1 and the crawler block 3 have the same structure. The crawler block 1 is an axisymmetric structure. On one side, the connecting block 1 on the crawler block 1 and the connecting block 2 cooperate with the connecting block 3 of the same structure on the crawler block 3, and the connecting rod 2 is inserted for connection. Therefore, a complete closed crawler can be completed by assembling the crawler blocks required for the construction vehicle in the same way. When the crawler is working, when the crawler block 1 contacts the ground at the bottom of the construction vehicle, due to the self-weight of the construction vehicle, the rubber buffer plate 8 of the crawler block 1 is compressed, and multiple resilient members 15 inside undergo elastic deformation. At this time, the seal 16 in the original relaxed state is compressed, so that the rubber block 18 on the seal 16 cooperates with the seal hole 19 on the rubber buffer plate 8, and the seal hole 19 deforms to block the seal hole 19. At this time, the air inside the rubber buffer plate 8 cannot be discharged. Combining with the material properties of the rubber buffer plate 8, the rubber buffer plate 8 can support the construction vehicle well and effectively absorb and reduce the impact caused by the road surface during the movement of the construction vehicle. In addition, the anti-slip block 9 outside the rubber buffer plate 8 can prevent the construction vehicle from slipping and increase the friction.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
