[0002] The quay crane, also known as the shore container crane, is a special equipment for port container loading and unloading. Currently, the port container loading and unloading equipment is mainly based on conventional single-trolley quay cranes. With the obvious trend of large-scale container transport ships, ports have put forward higher requirements on the performance of container quay cranes. The traditional method of relying solely on increasing the number of quay cranes at the terminal has become increasingly difficult to meet the higher demand for terminal loading and unloading efficiency due to larger container volumes.

[0003] The existing quay crane trolley brake is usually an octagonal structure, which uses a hydraulic pump to drive the connecting arm and brake parts connected to it to engage the moving wheel for braking. Emergency grinding braking is mainly performed through two side wall brake parts. The braking effect is slightly poor and there is room for further improvement.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

Obviously, the embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0025] As introduced in the background technology, in order to solve the deficiencies in the existing technology and the above technical problems, this application proposes an automatic centering compensation brake for a quay crane trolley.

[0026] See also Figure 1 - Figure 5A quay crane trolley automatic centering compensation brake includes a main body component 1, the main body component 1 includes a base 11, a fixing frame 12 and a hydraulic pump 13 are fixed on the base 11, the fixing frame 12 includes a transverse axis 121 fixed to the upper surface of the base 11, and a longitudinal axis 122 is hinged at both ends of the transverse axis 121, one of the longitudinal axes 122 is hinged to a main rod body 123, and the other longitudinal axis 122 is hinged to a connecting piece 124, the main rod body 123 is hinged to the connecting piece 124 at one end away from the longitudinal axis 122 hinged thereto, and the telescopic end of the hydraulic pump 13 is hinged to the connecting piece 124; a brake assembly is also provided on the base 11 2. The brake assembly 2 includes a brake member 21 hinged on the longitudinal axis 122, an elastic pull rod 28 is fixed on the base 11, and a brake member 27 is fixed to the telescopic end of the elastic pull rod 28. A slide groove 22 is provided on the transverse axis 121, and a slider 23 is provided in the slide groove 22. A connecting rod 231 is fixed to one end of the slider 23, and a spring 24 is further provided on the outer peripheral side of the connecting rod 231. The connecting rod 231 passes through the slide groove 22 at one end away from the slider 23 and is rotatably connected to a sliding wheel 26. A connecting rod 231 is further hinged on the slider 23, and the connecting rod 231 is hinged to the transverse axis 121 at one end away from the slider 23.

[0027] When using the device, it is installed on the pulley of the quay crane trolley. When in use, the hydraulic pump 13 provides power to push the fixed frame 12, and then the longitudinal axis 122 of the fixed frame 12 is engaged so that the brake member 21 is attached to the edge of the quay crane trolley pulley for braking. This is a prior art and will not be described in detail here. What is different from the traditional device is that a brake member 27 is provided for further braking. When the longitudinal axis 122 is engaged, the slider 23 is pushed toward the brake member 2 27 by the connecting rod 231. One end of the slider 23 is connected to the connecting rod 231, and a sliding wheel 26 is provided on the connecting rod 231. Under the push of the slider 23, the slider 23 squeezes the brake member 2 27, causing it to move upward, and cooperate with the brake member 1 21 to brake the quay crane trolley pulley, thereby improving the braking efficiency.

[0028] Furthermore, two brake members 21 are provided, which are mirror-imaged and arranged on opposite sides of the two longitudinal axes 122; only when the two brake members 21 are engaged can better braking be performed.

[0029] Furthermore, each brake member 21 includes a connecting plate 211 hinged on the longitudinal axis 122, and a brake disc 212 is slidably connected to one side of the connecting plate 211. Both sides of the connecting plate 211 are rotatably connected to elastic rods 213, and the telescopic ends of the elastic rods 213 are rotatably connected to the brake disc 212.

[0030] When braking, the hydraulic pump 13 and the fixed frame 12 cooperate to make the two brake parts 21 engage with the quay crane trolley pulley. First, the brake disc 212 contacts the quay crane trolley pulley and brakes under the action of friction. First, the brake disc 212 is movably set on the connecting plate 211. When braking, the brake disc 212 will first rotate with the quay crane trolley pulley under the action of friction. When the brake disc 212 rotates, it is preliminarily braked due to the action of the spring 24. There are four springs 24, two on one side, which are arranged in opposition. When braking, one generates a pulling force to pull the brake disc 212 for preliminary deceleration, and the elastic rod 213 on the opposite side generates a thrust for braking. The quay crane trolley pulley can be preliminarily decelerated first and then braked by the cooperation of the hydraulic pump 13 and the fixed frame 12 to further improve its braking effect.

[0031] Furthermore, two elastic rods 213 are provided on one side of each brake disc 212 , which can greatly improve the braking effect as described above.

[0032] Furthermore, the slide groove 22, slider 23, support rod 25, spring 24, sliding wheel 26 and connecting rod 231 on the same side are a group, and two groups are arranged in a mirror image. Through the two-group design, when the traditional fixing frame 12 is normally used for braking, the device structure pushes the brake part 27 to brake, thereby improving the braking efficiency.

[0033] Furthermore, the cross-section of the second brake member 27 is inverted conical, and the two sliding wheels 26 are arranged close to the side walls of the second brake member 27. When braking, the sliding wheels 26 push the second brake member 27 toward the pulley direction of the quay crane trolley, ultimately achieving a braking effect.

[0034] Working principle: When using the device, install it on the pulley of the quay crane trolley. When in use, the hydraulic pump 13 provides power to push the fixed frame 12, and then the longitudinal axis 122 of the fixed frame 12 is engaged so that the brake part 21 is attached to the edge of the quay crane trolley pulley for braking. This is a prior art and will not be described in detail here. What is different from the traditional device is that a brake part 27 is provided for further braking. When the longitudinal axis 122 is engaged, the slider 23 is pushed toward the brake part 2 27 by the connecting rod 231. One end of the slider 23 is connected to the connecting rod 231, and a sliding wheel 26 is provided on the connecting rod 231. Under the push of the slider 23, the slider 23 squeezes the brake part 2 27, causing it to move upward and cooperate with the brake part 1 21 to brake the quay crane trolley pulley, thereby improving the braking efficiency.

[0035] At the same time, the brake member 21 also includes a brake disc 212 and an elastic rod 213. When braking, the hydraulic pump 13 and the fixed frame 12 cooperate to make the two brake members 21 engage with the quay crane trolley pulley. First, the brake disc 212 contacts the quay crane trolley pulley and brakes under the action of friction. First, the brake disc 212 is movably arranged on the connecting plate 211. When braking, the brake disc 212 will first rotate with the quay crane trolley pulley under the action of friction. When the brake disc 212 rotates, it is preliminarily braked due to the action of the spring 24. There are four springs 24, two on one side, which are arranged in opposition. When braking, one generates a pulling force to pull the brake disc 212 for preliminary deceleration, and the elastic rod 213 on the opposite side generates a thrust for braking. The quay crane trolley pulley can be preliminarily decelerated first and then braked by the cooperation of the hydraulic pump 13 and the fixed frame 12, thereby further improving its braking effect.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
