DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-4The present invention provides a technical solution for a track roller for engineering machinery with a braking structure. The technical solution comprises a track roller body 1, wherein upper and lower ends of the outer peripheral surface of the track roller body 1 are provided with limiting assemblies for limiting and fixing the track roller body 1. The limiting assemblies include a first arcuate brake block 2 and a second arcuate brake block 3 provided at both ends of the upper and lower surfaces of the outer peripheral side wall of the track roller body 1. The two sets of first arcuate brake blocks 2 and the two sets of second arcuate brake blocks 3 are fixedly connected to the opposing outer surfaces by a connecting plate 4. At the same time, first brake pads 6 and second brake pads 7 corresponding to the upper and lower ends of the outer peripheral side wall of the track roller body 1 are fixedly mounted on the corresponding outer surfaces of the two sets of first arcuate brake blocks 2 and the two sets of second arcuate brake blocks 3. The bracket 5 drives the first and second arcuate brake blocks 2 and 3 toward each other, thereby causing the first and second brake pads 6 and 7 to move toward each other until the outer surfaces of the first and second brake pads 6 and 7 contact the outer peripheral surface of the track roller body 1 and generate friction, thereby quickly and promptly braking the track roller body 1 and stopping its rotation. The structure is convenient to operate and use.

[0023] A driving assembly is provided on one side of the outer side of the supporting wheel body 1, and the driving force assembly is fixedly connected to the limit assembly through a connecting piece. The driving assembly includes a pedal 16 and a connecting sleeve 17 provided on one end of the horizontal plate 14. A first through-type opening 18 is provided on the outer bottom of the connecting sleeve 17. A third vertical plate 19 is rotatably connected to the outer side wall of one end of the outer top of the horizontal plate 14. One end of the third vertical plate 19 extends along the first opening 18 to the inside of the connecting sleeve 17, and a second through-type opening 20 is provided on the outer side wall of the connecting sleeve 17. A first square plate 21 is rotatably connected to the end of the outer side wall of the pedal 16 close to the connecting sleeve 17. One end of the first square plate 21 extends along the second opening 20 to the connecting sleeve. The interior of the connecting sleeve 17, the interior of the connecting sleeve 17 and the outer top of the third vertical plate 19 are fixedly installed with a top plate 23, and the outer top of the top plate 23 is fixedly installed with a second square plate 22. The ends of the first square plate 21 and the second square plate 22 that are close to each other are both inclined and fit together. The inner bottom surface of the connecting sleeve 17 and the outside of the third vertical plate 19 are fixedly sleeved with a return spring 24, one end of the return spring 24 is fixedly connected to the outer bottom of the top plate 23, and a connecting frame 25 is installed on the top of the outer walls of both sides of the pedal 16 to rotate together. At the same time, a connecting block 26 is fixed on the top of the outer walls of both sides of the connecting sleeve 17, and a through-type threaded hole is opened on the outer top of the two groups of connecting blocks 26. First, the pedal 16 and the connecting sleeve 17 are fixed to the machine body through the connecting frame 25 and the connecting block 26. When in use, the pedal 16 is first pressed to cause it to tilt and rotate at an angle and allow the first square plate 21 to move laterally along the second opening 20 inside the connecting sleeve 17. Under the action of mutual fit, the second square plate 22 is pushed to drive the third vertical plate 19 to move back and forth downward along the first opening 18, and then, with the assistance of the connecting piece, the limiting assembly is driven to achieve the effect of limiting and fixing the supporting wheel body 1.

[0024] The connecting member includes a first straight plate 8 and a second straight plate 9, respectively fixedly mounted at the center positions of opposite outer surfaces of the two sets of brackets 5. First and second fixing blocks 10, 11 are rotatably connected to the outer walls of opposite ends of the first and second straight plates 8, 9, respectively. Meanwhile, a transverse plate 14 is rotatably connected to the outer sides of the other opposite ends of the first and second straight plates 8, 9, via first and second vertical plates 12, 13, respectively. A third fixing block 15 is rotatably connected to the center position of the outer wall of the transverse plate 14. The first and second fixing blocks 10, 11, and third fixing block 15 are first fixedly mounted to the machine body. The transverse plate 14 is then reciprocated up and down, thereby pushing the first and second vertical plates 12, 13, driving the first and second straight plates 8, 9 toward or away from each other. This transmits driving force to the brackets 5, causing the brackets 5 to move relative to each other, thereby achieving a braking effect.

[0025] The working principle of the present utility model is as follows: when in use, the supporting wheel body 1, the connecting frame 25 on the pedal 16, the connecting block 26 on the connecting sleeve 17, and the first fixing block 10, the second fixing block 11, and the third fixing block 15 are first installed on the body of the engineering machinery in sequence, and then the pedal 16 is pressed to cause an angle tilt on the connecting frame 25, thereby pushing the first square plate 21 to move laterally along the second opening 20 inside the connecting sleeve 17, and at the same time, under the action of mutual contact, the second square plate 22 is pushed to drive the third vertical plate 19 to move back and forth downward along the first opening 18.

[0026] At the same time, when the third vertical plate 19 moves downward, the horizontal plate 14 is synchronously driven to rotate on the third fixed block 15, and one end of the horizontal plate 14 moves downward, and under the auxiliary connection of the first vertical plate 12 and the second vertical plate 13, the first straight plate 8 and the second straight plate 9 are driven to move relative to each other on the first fixed block 10 and the second fixed block 11.

[0027] At the same time, when the first straight plate 8 and the second straight plate 9 move relative to each other, the bracket 5 drives the first brake pad 6 and the second brake pad 7 on the first arc-shaped brake block 2 and the second arc-shaped brake block 3 to approach each other until the outer surfaces of the first brake pad 6 and the second brake pad 7 touch the outer peripheral surface of the supporting wheel body 1 and generate friction, thereby quickly and timely braking the supporting wheel body 1 and gradually stopping its rotation.

[0028] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
