[0004] After the connecting plate of the device is inserted into the slot, it is deformed and stuck in the slot, so that the mounting plate can be quickly fixed and the installation efficiency can be improved. However, the device does not have a structure that is convenient for removing the rubber pad. The rubber pad is a consumable material and will wear out during long-term use and needs to be replaced. The rubber will be embedded in the inside of the slot under the influence of the extrusion pressure, which is not easy to remove and needs to be loosened by knocking with a hammer. This disassembly method will cause certain damage to the track, thereby affecting the service life of the track.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original road surface protection pad structure to prevent track wear. Utility Model Content

[0014] Compared with the prior art, the utility model has the beneficial effect that the road surface protection pad for preventing track wear is provided with:

[0015] 1. Quick-release structure. When the rubber pad needs to be replaced, the hexagonal bolts are rotated to separate the two sides of the rubber pad from the positioning frame. After separation, the two sides of the rubber pad are in an active state. At this time, the first telescopic spring inside the positioning frame pushes the sliding block to slide along the inside of the slide groove through its own elastic force. When the sliding block slides inside the slide groove, it drives the upper support rod to rotate.

This disassembly method is not only efficient but also less harmful to the crawler and the positioning frame.

[0016] 2. Anti-wear structure. When the crawler is used for a long time and the wear degree of the rubber pads on the outside of the crawler needs to be detected, the engineering vehicle is first driven to a flat road. At this time, by observing the crawler observation port attached to the road, the wear condition of both sides of the rubber pads can be judged according to the changes of the bubbles on the inside of the level gauge, and the corresponding rubber pads can be replaced in time, which has better accuracy than naked eye observation;

[0017] Furthermore, when it is necessary to remove the spirit level inside the rubber pad, the resistance blocks on both sides can be manually moved to squeeze the second telescopic spring to make the sliding rod slide along the inside of the spirit level, thereby separating the tail end of the sliding rod from the snap-on fittings on the inside of the empty groove. After separation, the spirit level can be taken out from the empty groove at the bottom of the worn rubber pad and installed on the inside of a new rubber pad, thereby achieving a cost-saving effect.

[0027] 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.

[0028] Please refer to Figures 1 - 8 , the present utility model provides a technical solution: a road protection cushion for preventing crawler belt wear, including:

[0029] Embodiment 1: As Figures 1 - 6 shown in the technical solution, the present utility model provides a technical solution: a road protection cushion for preventing crawler belt wear, discloses: a crawler belt 1, a positioning frame 2 is equidistantly installed on the outer side of the crawler belt 1; a rubber cushion block 3, the rubber cushion block 3 is installed on the outer side of the positioning frame 2; anti-slip stripes 4, the anti-slip stripes 4 are equidistantly installed on the outer side of the rubber cushion block 3; threaded holes 5, the threaded holes 5 are opened on the inner sides of the rubber cushion block 3 and the positioning frame 2, and the threaded holes 5 opened on the inner side of the positioning frame 2 are connected by hexagon bolts 6; an observation port 9, the observation port 9 is opened on the inner side of the crawler belt 1, and the observation port 9 and the positioning frame 2 are distributed in a one-to-one correspondence; a quick-release component 7, the quick-release component 7 is installed on the inner side of the positioning frame 2; a detection component 8, the detection component 8 is installed on the inner side of the rubber cushion block 3; wherein, through the quick-release component 7, the rubber cushion block 3 can be ejected from the inner side of the positioning frame 2; through the detection component 8, the outer surface of the rubber cushion block 3 can be subjected to wear detection;

[0030] The quick-release component 7 includes a support plate 701 and a chute 702. The support plate 701 is fixedly installed inside the positioning frame 2, and chutes 702 are formed on both the left and right sides of the support plate 701. The quick-release component 7 further includes a first telescopic spring 703, a sliding block 704, a support rod 705, and a top plate 706. The first telescopic spring 703 is fixedly installed inside the chute 702, and the tail end of the first telescopic spring 703 is fixedly connected to the sliding block 704. The sliding block 704 is slidably connected inside the chute 702. A support rod 705 is rotatably connected to the outside of the sliding block 704, and the upper end of the support rod 705 is rotatably connected to the top plate 706. Two groups of support rods 705 are symmetrically arranged about the midpoint of the top plate 706. The top plate 706 is arranged inside the positioning frame 2, and the top plate 706 and the rubber cushion block 3 are distributed in a vertical correspondence.

[0031] When installing the rubber cushion block 3, first place the rubber cushion block 3 on the upper end of the positioning frame 2, so that it presses the first telescopic spring 703 inside the positioning frame 2 until the threaded holes 5 inside the positioning frame 2 and the threaded holes 5 on both sides of the rubber cushion block 3 are in a flush state. Subsequently, use a hexagon bolt 6 to connect the two threaded holes 5 in series, so that the rubber cushion block 3 is fixed on the outer surface of the positioning frame 2, protecting the inner crawler 1 during the operation of the engineering vehicle. When the rubber cushion block 3 needs to be replaced, by rotating the hexagon bolt 6, the two sides of the rubber cushion block 3 are separated from the positioning frame 2. After separation, the two sides of the rubber cushion block 3 are in a movable state. At this time, the first telescopic spring 703 inside the positioning frame 2 pushes the sliding block 704 to slide along the inside of the chute 702 through its own elastic force. When the sliding block 704 slides inside the chute 702, it will drive the upper support rod 705 to rotate. The rotation of the support rod 705 will push the upper connected top plate 706 to move upward, thereby ejecting the upper rubber cushion block 3 and quickly separating it from the positioning frame 2. This disassembly method is not only efficient but also causes less damage to the crawler 1 and the positioning frame 2.

The detection component 8 further includes a sliding rod 803 and a contact block 804. The sliding rod 803 is slidably connected to the inside of the level 802, and the tail end of the sliding rod 803 is snap-connected to the inside bayonet of the empty slot 801. A contact block 804 is fixedly installed on the outside of the sliding rod 803. The detection component 8 further includes a second telescopic spring 805, and both ends of the second telescopic spring 805 are connected to the contact block 804 and the level 802 respectively.

[0033] This structure has better accuracy than naked eye observation when the level 802 on the inside of the rubber pad 3 needs to be removed, and when it is necessary to manually move the resistance blocks 804 on both sides, the second telescopic spring 805 can be squeezed to make the sliding rod 803 slide along the inside of the level 802, so that the tail end of the sliding rod 803 is separated from the bayonet on the inside of the vacant groove 801, and after separation, the level 802 can be taken out from the vacant groove 801 at the bottom of the worn rubber pad 3 and installed on the inside of a new rubber pad 3, thereby achieving the effect of cost saving.
