Its tensile strength, tear strength, wear resistance and other properties are 3-5 times higher than ordinary rubber. It is suitable for welding processing of cylinders.

[0003] The patent with the patent authorization announcement number CN215153651U discloses an electric polyurethane roller, which uses a slider to slide on the inner wall of the connection box, so that the spring and the shock-absorbing pad can provide overall shock absorption for the equipment. When the polyurethane wheel sleeve rotates with the wheel hub, the brush plate and the scraper can rub against the surface of the polyurethane wheel sleeve to scrape off the sand and other impurities adhering to the polyurethane wheel sleeve. However, the polyurethane roller provided by the patent still has shortcomings in actual use. When the equipment equipped with the electric polyurethane roller is in use, it cannot stop and brake quickly and effectively, and it is easy to collide with surrounding objects, which poses certain safety hazards.

[0004] Therefore, it is necessary to provide a polyurethane roller with a brake structure, through the arrangement of a pedal, an arc-shaped mounting plate and a limit frame, etc., the polyurethane roller body can be braked and stopped in time and effectively. Utility Model Content

DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0022] Example 1: A polyurethane roller with a brake structure, see Figure 1 and Figure 2 As shown, it includes a first fixing frame 1 and a polyurethane roller body 2, the first fixing frame 1 is rotatably provided with the polyurethane roller body 2, the top of the first fixing frame 1 is provided with four mounting holes for facilitating its installation at the bottom of the equipment, and also includes a brake pad 3, a fixing plate 4, an elastic member 401, an arc-shaped mounting plate 5, a first rubber pad 6, a limiting frame 7, a connecting frame 8, a fixing rod 9 and a pedal 10, a fixing rod 9 is transversely fixedly penetrated through the middle of the first fixing frame 1, and pedals 10 are rotatably provided on both sides of the fixing rod 9, the fixing plates 4 are both installed on both sides of the first fixing frame 1 by welding, a limiting frame 7 is slidably provided on the fixing plate 4, the limiting frame 7 slides up and down along the fixing plate 4, the bottom of the limiting frame 7 is fixedly connected with the arc-shaped mounting plate 5 by welding, four elastic members 401 are wound around the limiting frame 7, the first rubber pad 6 is installed on the arc-shaped mounting plate 5 by bonding, the brake pads 3 are fixedly connected with both sides of the polyurethane roller body 2 by welding, and the tops of the limiting frames 7 on both sides are hingedly connected with the connecting frames 8 together with the pedals 10.

[0023] When the polyurethane roller needs to brake while rolling, the pedal 10 is pressed to rotate on the fixing rod 9. The pedal 10 pulls the two limit frames 7 to slide upward along the fixing plate 4 through the connecting frames 8 on both sides, so that the two limit frames 7 drive the arc-shaped mounting plate 5 to move upward. At this time, the elastic member 401 is compressed and deformed by force, and the first rubber pad 6 on the arc-shaped mounting plate 5 contacts and rubs with the brake pads 3 on both sides of the polyurethane roller body 2, so that the rotation of the polyurethane roller body 2 is decelerated and stopped, and the equipment on which the polyurethane roller is installed stops moving forward; after the elastic member 401 is released, the elastic member 401 loses the force and returns to its original state, thereby pushing the limit frame 7 to slide downward and reset along the fixing plate 4, so that the arc-shaped mounting plate 5 drives the first rubber pad 6 to break away from the contact with the brake pad 3, and the limit frame 7 pulls the pedal 10 to rotate and reset along the fixing rod 9 through the connecting frame 8.

[0024] Example 2: Based on Example 1, refer to Figure 3 As shown, it also includes first mounting frames 12 installed on both sides of the first fixed frame 1 by bolt connection, and a swing frame 14 is rotatably arranged on the two first mounting frames 12. The swing frame 14 and the two first mounting frames 12 are fixedly connected with a first torsion spring 13 by welding. A triangular roller frame 15 for supporting the ground is rotatably arranged on one side of the swing frame 14 away from the first mounting frame 12, and an extrusion block 11 for pushing the swing frame 14 is installed at the bottom of the pedal 10 by bolt connection.

[0025] When the pedal 10 is stepped on, the pedal 10 pushes the swing frame 14 on the two first mounting frames 12 to rotate toward the side close to the polyurethane roller body 2 through the squeezing block 11. At this time, the first torsion spring 13 is twisted and deformed by the force, and the swing frame 14 drives the triangular roller frame 15 to contact the ground. The triangular structure of the triangular roller frame 15 is supported on the ground, increasing the contact friction with the ground, so that the polyurethane roller body 2 is further decelerated and stopped; after the pedal 10 drives the squeezing block 11 to reset, the first torsion spring 13 loses the force and returns to its original state, thereby driving the swing frame 14 to rotate in the opposite direction and reset, so that the swing frame 14 rises and breaks away from the contact with the ground.

[0026] See also Figure 4 As shown, it also includes a second fixing frame 16 installed on the first fixing frame 1 by means of bolt connection, a second mounting frame 17 is rotatably arranged on the second fixing frame 16, two second torsion springs 1701 are fixedly connected to the second mounting frame 17 and the second fixing frame 16 by means of welding, a second rubber pad 18 is installed on the second mounting frame 17 by means of bolt connection, and a top plate 19 for pushing the second mounting frame 17 is installed on the top of the limiting frames 7 on both sides by means of bolt connection, and the second mounting frame 17 is V-shaped, so that the top plate 19 can push the second mounting frame 17.

[0027] When the two limiting frames 7 slide upward along the fixing plate 4, the two limiting frames 7 drive the top plate 19 to move upward and push the second mounting frame 17, so that the second mounting frame 17 drives the second rubber pad 18 to rotate on the second fixing frame 16. At this time, the second torsion spring 1701 is twisted and deformed by force, and the second mounting frame 17 contacts and rubs with the polyurethane roller body 2 through the second rubber pad 18, further decelerating and braking the polyurethane roller body 2; after the limiting frames 7 drive the top plate 19 to slide downward and reset, the second torsion spring 1701 loses the force and returns to its original state, thereby driving the second mounting frame 17 to rotate in the opposite direction and reset, so that the second rubber pad 18 is out of contact with the polyurethane roller body 2.

[0028] See also Figure 1 and Figure 3 As shown, a friction pad 20 is installed on the top of the pedal 10 by bonding, a scraper block 21 is installed on the lower part of the first fixing frame 1 by bolt connection, and a plurality of V-shaped grooves 22 are opened on the polyurethane roller body 2.

[0029] The friction pad 20 is used to increase the friction when in contact with the pedal 10, to prevent the foot from slipping and being unable to press the pedal 10 in time to brake; when the polyurethane roller body 2 rotates, the scraper block 21 can scrape off the mud and embedded gravel attached to the polyurethane roller body 2, reduce the weight of the polyurethane roller body 2, and prevent the gravel from penetrating into the polyurethane roller body 2 and damaging it; the groove 22 can increase the friction between the polyurethane roller body 2 and the ground, have better grip, and are not easy to slip.
