Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Reference Figure 1-Figure 7 As shown: a brake mechanism of a self-propelled trolley, including a connecting rod 2 4, a connecting piece 2 41 is fixedly connected to the top of the connecting rod 2 4, a brake assembly 2 is arranged on one side of the connecting piece 2 41, the brake assembly 2 includes a fixing piece 21, a supporting bar 1 23 and a driving arm 26, one side of the driving arm 26 is hinged with the connecting piece 2 41, one side of the driving arm 26 is engaged with a limiting piece 34, one side of the limiting piece 34 is rotatably connected with an auxiliary rod 3, a reset spring 33 is installed on the inner wall of the auxiliary rod 3, one end of the reset spring 33 is fixedly connected with the limiting piece 34 One side of the driving arm 26 is engaged with the fixing member 21, and a positioning block 25 is engaged with one side of the fixing member 21 and the driving arm 26. One side of the driving arm 26 is fixedly connected with a support bar 24, and a guide groove is provided on one side of the support bar 24. An extension block is slidably connected in the guide groove, and one end of the extension block is fixedly connected to the support bar 1 23. A limit bolt 241 is provided between the support bar 24 and the extension block through a threaded connection, and one end of the support bar 1 23 is fixedly connected to the fixing member 21, and brake wheels 22 are installed on both sides of the fixing member 21.

[0022] The second connecting rod 4 can assist the installation of the riding mechanism, and the second connecting member 41 can assist the connection between the second connecting rod 4 and the driving arm 26, so as to facilitate the subsequent riding mechanism and the passenger to drive the driving arm 26 to rotate. The engagement of the limiting member 34 with the driving arm 26 can realize the connection between the limiting member 34 and the driving arm 26, and then when the auxiliary rod 3 is subjected to the force, the auxiliary rod 3 can be driven to rotate synchronously with the driving arm 26, so as to control the separation of the brake wheel 22 at the top of the driving arm 26 from the wire rope, so as to realize the normal walking of the whole device. The two ends of the reset spring 33 are respectively connected to the auxiliary rod 3 and the limiting member 34, which can assist the subsequent reset of the limiting member 34 and reduce the interference of the limiting member 34 on the movement of the driving arm 26 when the driving arm 26 rotates in the opposite direction. The second support bar 24 and the guide groove can be used to guide the installation and disassembly of the extension block, so as to facilitate the installation of the support bar 1 23 on the top of the second support bar 24. The limiting bolt 241 can be used to fix the connection between the extension block and the second support bar 24, so as to realize the fixation. The fixing of the fixing member 21 and the driving arm 26 is achieved by using the positioning block 25 to engage with the fixing member 21 and the driving arm 26, which can reduce the looseness of the fixing member 21 after installation and ensure the connection effect of the fixing member 21 and the driving arm 26. At the same time, the support bar 1 23, the support bar 24 and the driving arm 26 form a triangular structure, which can improve the strength of the fixing member 21 and reduce the deformation of the fixing member 21 after being subjected to force, thereby ensuring the stable use of the fixing member 21 and facilitating the rapid disassembly and replacement of the brake wheel 22 after wear. At the same time, no matter how the angle of the wire rope changes, the contact area between the brake wheel 22 and the wire rope is always guaranteed to remain unchanged. The brake assembly 2 adopts a lever mechanism. The greater the weight on the manned mechanism, the greater the extrusion force of the brake wheel 22 driven by the lever structure on the wire rope will be, and the braking force will increase. Similarly, the greater the angle of the wire rope, the greater the force arm of the manned mechanism will be, and the greater the extrusion force of the brake wheel 22 driven by the lever structure on the wire rope will be, and the braking force will increase; the stability and safety of the brake can be greatly improved.

[0023] Embodiment 2: According to Figure 1-Figure 5 As shown, a guide rod 261 is fixedly connected to one side of the driving arm 26, and an arc guide rail 262 is slidably connected to one end of the guide rod 261. An arc groove is provided on one side of the arc guide rail 262. A hinge 29 is fixedly connected to one side of the driving arm 26. A telescopic rod 28 is hinged to one side of the inner wall of the hinge 29. One end of the telescopic rod 28 is hinged to a hinge 1 27. A pull rod 31 is threadedly connected to one end of the auxiliary rod 3. A handle 32 is fixedly connected to the outer ring surface of the pull rod 31. The outer ring surface of the handle 32 is compounded with a rubber anti-slip layer.

[0024] In this embodiment, the guide rod 261 can be used to connect the driving arm 26 with the arc guide rail 262. The sliding of the guide rod 261 inside the arc guide rail 262 can guide the rotation of the driving arm 26, thereby limiting the rotation range of the driving arm 26. The two ends of the telescopic rod 28 are respectively hinged to the hinge 1 27 and the hinge 2 29. The inner rod and the outer rod of the telescopic rod 28 are slidably connected. The inclination angle of the telescopic rod 28 when in use can be adjusted by the hinge 1 27 and the hinge 2 29. The use length of the entire telescopic rod 28 can be adjusted by the inner rod of the telescopic rod 28 sliding inside the outer rod. As a result, when the driving arm 26 rotates, the length and inclination angle of the telescopic rod 28 change accordingly, which can reduce The telescopic rod 28 interferes with the movement of the driving arm 26 when it rotates, and the telescopic rod 28 can also be used to support both sides of the driving arm 26 to improve the stability of the driving arm 26 when it rotates and avoid separation of the entire device from the wire rope. The pull rod 31 and the auxiliary rod 3 are connected by threads, so the insertion depth of the pull rod 31 inside the auxiliary rod 3 can be adjusted, and then the use length of the pull rod 31 can be changed, which is convenient for people with different arm lengths to use. The pull rod 31 can be used to support the handle 32, which is convenient for passengers to hold and is more conducive to passengers applying force to the pull rod 31 and the auxiliary rod 3. The rubber anti-slip layer can reduce the sliding of the passenger-driven pull rod 31 and the auxiliary rod 3 when they rotate, and provide stable power for the auxiliary rod 3 and the pull rod 31.

[0025] Embodiment 3: According to Figure 1-Figure 7 As shown, a deceleration assembly 1 is arranged on the top of the pull rod 31, and the deceleration assembly 1 includes a deceleration plate 11, a connecting rod 15 and a magnetic seat 17. The bottom of the magnetic seat 17 is fixedly connected to the hinge 27, and one side of the magnetic seat 17 is fixedly connected to a connecting member 19. The inner wall of the connecting member 19 is fixedly connected to the connecting rod 15, and one side of the connecting rod 15 is fixedly connected to the arc guide rail 262. One side of the connecting rod 15 is fixedly connected to a transverse axis 14, and the transverse axis 14 is rotatably connected to the auxiliary rod 3. One end of the transverse axis 14 is fixedly connected to a plug-in rod 141, and the plug-in rod 141 is inserted through the driving arm 26, the plug-in rod 141 is rotatably connected to the driving arm 26, one side of the driving arm 26 is overlapped with the inner wall of the auxiliary rod 3, a fixing bolt 13 is inserted through the two magnetic seats 17, one side of the magnetic seat 17 is rotatably connected with the walking wheel 12, a speed increaser 16 is installed inside the walking wheel 12, one end of the speed increaser 16 passes through one of the magnetic seats 17 and is fixedly connected to the reduction disc 11, a placement groove is opened on one side of the magnetic seat 17, a permanent magnet 18 is installed in the placement groove, and one side of the permanent magnet 18 is overlapped with the reduction disc 11.

[0026] In this embodiment, the connecting rod 15 can be used to support one side of the arc guide rail 262 to ensure the stable installation and use of the arc guide rail 262 on both sides of the driving arm 26. The connection between the magnetic seat 17 and the connecting rod 15 can be achieved through the connecting piece 19, so as to support and reinforce the connecting rod 15. The horizontal axis 14 and the plug rod 141 can assist the rotation adjustment of the driving arm 26 between the two connecting rods 15. The fixing bolt 13 can be used to connect and reinforce the two magnetic seats 17 to ensure that the walking wheel 12 rotates stably on one side of the magnetic seat 17. At the same time, the magnetic seat 17 can support the top of the hinge 27. The support is convenient for the installation and use of the top of the hinge 27 and the end of the telescopic rod 28. The magnetic base 17 can also support the installation of the speed increaser 16. The connection between the speed increaser 16 and the speed reduction disk 11 can drive the speed reduction disk 11 to rotate on one side of the magnetic base 17. The speed reduction disk 11 rotates at a high speed driven by the speed increaser 16, cuts the magnetic lines on the magnetic base 17, and forms eddy currents on the speed reduction disk 11. The counter force formed by the eddy current acts on the speed reduction disk 11, and the speed reduction disk 11 applies a reaction force to the speed increaser 16, adjusts the rotation speed of the walking wheel 12, and realizes the smooth walking of the trolley, thereby improving the safety of the entire device when in use.

[0027] The method of using the device and the working principle are as follows: first, a passenger mechanism is installed at the bottom of the connecting rod 24, and the passenger can sit on the passenger mechanism, and then hold the handle 32 with both hands, drive the pull rod 31 and the auxiliary rod 3 to rotate with the horizontal axis 14 as the axis, so that the limiter 34 is first engaged with the driving arm 26, and then the pull rod 31 is continued to rotate. At this time, the limiter 34 applies a force to the driving arm 26, so that the driving arm 26 rotates with the axis of the plug-in rod 141. When the driving arm 26 rotates, the guide rod 261 moves along the arc groove on one side of the arc guide rail 262, the length of the telescopic rod 28 shrinks, and the inclination angle of the telescopic rod 28 changes, so that the telescopic rod 28 is aligned with the steel wire. The brake wheel 22 that is fitted with the rope is separated from the wire rope. At this time, under the guidance of the running wheel 12 on the deceleration component 1, the entire trolley can walk on the wire rope by itself. When walking, the speed reduction disc 11 rotates at a high speed under the drive of the speed increaser 16, cutting the magnetic lines of force on the magnetic seat 17, forming eddy currents on the speed reduction disc 11, and the counter-braking force formed by the eddy current acts on the speed reduction disc 11, and the speed reduction disc 11 applies a reaction force to the speed increaser 16 to slow down the running wheel 12. Since the size of the counter-braking torque is proportional to the rotation speed, that is, the faster the trolley goes down, the greater the reaction force applied by the speed reduction disc 11 to the speed increaser 16, thereby keeping the trolley running at a constant speed; When the passenger opens the handle 32, the limit member 34 is reset under the action of the reset spring 33, and the gravity of the manned structure and the passengers exerts a force on the drive arm 26, causing the drive arm 26 to rotate in the opposite direction along the plug-in rod 141. At this time, the guide rod 261 slides in the opposite direction, the telescopic rod 28 extends, and the inclination angle changes again, thereby moving the brake wheel 22 up until the brake wheel 22 contacts the wire rope to achieve braking. When braking the wire rope, no matter how the angle of the wire rope changes under the action of external force, the contact between the brake wheel 22 and the wire rope can always be guaranteed. The area remains unchanged, and the brake assembly 2 adopts a lever mechanism. The greater the weight on the manned mechanism, the greater the squeezing force of the brake wheel 22 driven by the lever structure on the wire rope will be, and the braking force will increase. Similarly, the greater the angle of the wire rope, the greater the force arm of the manned mechanism will be, and the greater the squeezing force of the brake wheel 22 driven by the lever structure on the wire rope will be, and the braking force will also increase. The braking effect of the brake assembly 2 can be ensured by increasing the pressure, thereby greatly improving the stability and safety of the brake, thereby reducing the safety hazards existing when the entire device is used; When the brake wheel 22 is severely worn due to long-term use, the positioning block 25 can be moved to the side away from the driving arm 26, so that the positioning block 25 is separated from the driving arm 26 and the fixing member 21 respectively, and the limiting bolt 241 is rotated to remove the fixing member 21 from one side of the driving arm 26. At this time, the bottom of the support bar 1 23 is separated from the support bar 24, and the brake wheel 22 can be quickly replaced.
