Abstract
Description
Technical Field
[0001] This invention relates to the field of windproof wedge technology, and in particular to a windproof wedge brake for a port machinery wheel. Background Technology
[0002] Port machinery windproof wedges are important devices used for windproof braking of equipment such as port cranes and gantry cranes. They are mainly used for wind protection during operation and as auxiliary braking during non-operational operation.
[0003] After long-term use, the top of the rail that contacts the wheel will wear down, causing the top surface of the rail to become sloping. The current technology is to insert an iron wedge directly into the gap between the two. However, after insertion, the sloping surface will cause a gap between the bottom of the iron wedge and the top of the rail, and a gap between the top and the wheel, which will prevent complete contact. This gap will reduce the coefficient of friction, so this will lead to unstable braking effect and increase safety risks. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0039] Example: Refer to Figures 1-8 A windproof wedge brake for a port machinery wheel, comprising a mounting mechanism 1, and further comprising:
[0040] Insertion mechanism 2, which is connected to installation mechanism 1, includes push rod motor 21, one end of push rod motor 21 is rotatably connected to connecting frame 22, two connecting plates 24 are rotatably connected inside connecting frame 22, and a rotating shaft 25 is rotatably connected inside connecting plate 24.
[0041] The fitting compensation mechanism 3 is connected to the insertion mechanism 2 and includes a connecting block 33. Movable grooves 34 are provided on both sides of the connecting block 33. A U-shaped part 31 is sleeved on the outside of the movable groove 34. A rotating shaft 32 is rotatably connected to the inside of the U-shaped part 31 and the connecting block 33. A rotating shaft 35 is rotatably connected to one side of the connecting block 33. A wedge 36 is fixed at one end of the rotating shaft 35.
[0042] The fitting compensation mechanism 3 also includes a rotating shaft 313 rotatably connected to one side of the wedge 36. One end of the rotating shaft 313 is fixed to the wedge 314, and the bottom of the wedge 314 is provided with multiple hydraulic cylinders 315.
[0043] The adaptive bonding cleaning mechanism 4 is connected to the installation mechanism 1.
[0044] The installation mechanism 1 includes a protective box 11, a docking part 12 is fixed on one side of the protective box 11, and one side of the docking part 12 is fixedly connected to the port machinery.
[0045] A buffer post 13 is fixed on the other side of the protective box 11.
[0046] The insertion mechanism 2 also includes a hinge 23 fixed to the inner wall of the top of the protective box 11, and the top of the push rod motor 21 is rotatably connected to the hinge 23.
[0047] The rotating shaft 25 is rotatably connected to the side wall of the protective box 11;
[0048] When the machine stops moving, the controller receives a braking command and controls the push rod motor 21 to extend. When it extends, it pushes the connecting frame 22 to rotate around the rotating shaft 25, pushing the fitting compensation mechanism 3 diagonally downward and inserting it between the track and the port machine wheel to limit the wheel of the port machine and prevent the wind from blowing the port machine and causing it to shift.
[0049] When the fitting compensation mechanism 3 moves diagonally downward, the bottom of the wedge 36 contacts the top of the track, and then the wedge 36 slides horizontally along the track towards the underside of the wheel.
[0050] The fitting compensation mechanism 3 also includes a double torsion spring 38 sleeved on the outside of the rotating shaft 35. One end of the double torsion spring 38 is fixed with a fixing block 37 and the other end is fixed with a fixing block 39.
[0051] Fixed block 37 is fixedly connected to connecting block 33, and fixed block 39 is fixedly connected to wedge 36; the main function of double torsion spring 38 is to ensure that wedge 36 can smoothly return to a horizontal state after deflecting to both sides.
[0052] The bottom of the wedge 36 is provided with an arc-shaped groove 312, and an L-shaped pull plate 311 is fitted inside the arc-shaped groove 312. One side of the L-shaped pull plate 311 is fixedly connected to the connecting block 33. When the wedge 36 deflects, the arc-shaped groove 312 deflects accordingly, while the L-shaped pull plate 311 is always fitted inside the arc-shaped groove 312. When the connecting block 33 pulls the wedge 36 away through the rotating shaft 35, the L-shaped pull plate 311 is subjected to force, thereby reducing the pulling force of the rotating shaft 35.
[0053] One side of the U-shaped part 31 is fixedly connected to the connecting bracket 22.
[0054] The fitting compensation mechanism 3 also includes an oil pump 316 fixed to the inner wall of the protective box 11;
[0055] Multiple hydraulic cylinders 315 are fixed inside the wedge 36. The multiple hydraulic cylinders 315 are connected by an oil supply pipe. An oil pressure sensor is installed on the oil supply pipe. The oil supply pipe is connected to the oil pump 316.
[0056] A hemispherical ball 310 is fixed to the movable end of the hydraulic cylinder 315;
[0057] After the fitting compensation mechanism 3 is inserted into the gap between the wheel and the track, the push rod motor 21 is turned off and the oil pump 316 is started. Hydraulic oil is simultaneously injected into multiple hydraulic cylinders 315 through the oil supply pipe, and the oil pressure sensor monitors the oil pressure in real time.
[0058] The inner rod of hydraulic cylinder 315 extends, driving hemispherical ball 310 to contact and push wedge 2 314 to rotate around pivot 4 313, while wedge 1 36 rotates around pivot 3 35. When a hydraulic cylinder 315 can no longer extend, hydraulic oil stops flowing into that cylinder and is instead injected into other hydraulic cylinders 315. Once all hydraulic cylinders 315 can no longer be injected with hydraulic oil, the oil pressure sensor detects that the oil pressure value has reached the standard and shuts off the oil pump 316. At this time, the extension of each hydraulic cylinder 315 is different, driving wedge 1 36 to tilt until its bottom is tightly fitted with the track, and wedge 2 314 tilts, its arc surface tightly fitting with the wheel. By supporting the two wedges, the two wedges tilt and fit tightly with the wheel and track respectively, significantly improving the coefficient of friction and effectively preventing displacement.
[0059] When extraction is required, the oil pump 316 is activated to draw back the hydraulic oil from the hydraulic cylinder 315. After the hydraulic cylinder 315 retracts, the frictional resistance between the second wedge 314 and the wheel, and between the first wedge 36 and the top of the track, is reduced, facilitating smooth extraction. This design avoids the extraction difficulties caused by the wedges being squeezed due to wind displacement of the port machinery, significantly extending the service life of the mechanical structure.
[0060] The adaptive bonding cleaning mechanism 4 includes a mounting block 41 fixed to one side of the protective box 11. Multiple cleaning rods 42 are sleeved inside the mounting block 41. The bottom end of the cleaning rod 42 is rotatably connected to a ball. A circular plate 43 is fixed to the top end of the cleaning rod 42. A spring 44 is fixed to the bottom of the circular plate 43. The spring 44 is sleeved on the outside of the cleaning rod 42. One end of the spring 44 is fixedly connected to the mounting block 41.
[0061] The port crane slides on the track. During the sliding process, the spring 44 pulls the circular plate 43 to push the cleaning rod 42 downward, so that the ball is always in contact with the top of the track. When the top of the track becomes inclined due to wear, the spring 44 pulls the cleaning rod 42 downward, so that the ball is always in contact with the track surface. When moving, the foreign objects on the top of the track are removed to avoid the foreign objects affecting the wedge when it is in position.
[0062] A controller is fixed on one side of the protection box 11. The controller is electrically connected to the push rod motor 21, the oil pump 316 and the oil pressure sensor.
[0063] Working principle:
[0064] The port crane slides on the track. During the sliding process, the spring 44 pulls the circular plate 43 to push the cleaning rod 42 downward, so that the ball is always in contact with the top of the track. When the top of the track becomes inclined due to wear, the spring 44 pulls the cleaning rod 42 downward, so that the ball is always in contact with the track surface. When moving, the foreign objects on the top of the track are removed to avoid the foreign objects affecting the wedge when it is in position.
[0065] When the machine stops moving, the controller receives a braking command and controls the push rod motor 21 to extend. When it extends, it pushes the connecting frame 22 to rotate around the rotating shaft 25, pushing the fitting compensation mechanism 3 diagonally downward and inserting it between the track and the port machine wheel to limit the wheel of the port machine and prevent the wind from blowing the port machine and causing it to shift.
[0066] When the fitting compensation mechanism 3 moves diagonally downwards, the bottom of wedge 36 contacts the top of the rail, and then wedge 36 slides horizontally along the rail towards the underside of the wheel. Since the rail is not a perfectly rigid body, wear at its top can cause the top surface of the rail to become inclined. At this time, a gap may appear between the bottom of wedge 36 and the top of the rail, preventing complete contact. This gap reduces the coefficient of friction and causes varying degrees of displacement during positioning. Furthermore, in the prior art, after the wedge positions itself against the wheel, strong winds push the port machinery to squeeze the wedge, increasing the coefficient of friction. Forcibly removing it would damage the mechanical structure and affect its service life.
[0067] After the fitting compensation mechanism 3 is inserted into the gap between the wheel and the track, the push rod motor 21 is turned off and the oil pump 316 is started. Hydraulic oil is simultaneously injected into multiple hydraulic cylinders 315 through the oil supply pipe, and the oil pressure sensor monitors the oil pressure in real time.
[0068] The inner rod of hydraulic cylinder 315 extends, driving hemispherical ball 310 to contact and push wedge 2 314 to rotate around pivot 4 313, while wedge 1 36 rotates around pivot 3 35. When a hydraulic cylinder 315 can no longer extend, hydraulic oil stops flowing into that cylinder and is instead injected into other hydraulic cylinders 315. Once all hydraulic cylinders 315 can no longer be injected with hydraulic oil, the oil pressure sensor detects that the oil pressure value has reached the standard and shuts off the oil pump 316. At this time, the extension of each hydraulic cylinder 315 is different, driving wedge 1 36 to tilt until its bottom is tightly fitted with the track, and wedge 2 314 tilts, its arc surface tightly fitting with the wheel. By supporting the two wedges, the two wedges tilt and fit tightly with the wheel and track respectively, significantly improving the coefficient of friction and effectively preventing displacement.
[0069] When extraction is required, the oil pump 316 is activated to draw back the hydraulic oil from the hydraulic cylinder 315. After the hydraulic cylinder 315 retracts, the frictional resistance between the second wedge 314 and the wheel, and between the first wedge 36 and the top of the track, is reduced, facilitating smooth extraction. This design avoids the extraction difficulties caused by the wedges being squeezed due to wind displacement of the port machinery, significantly extending the service life of the mechanical structure.
[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
