The invention relates to the field of parking braking, in particular to a parking braking protection device of an anti-explosion trackless rubber-tyred vehicle. Comprising a sealing box, a magnetic driving mechanism and a manual mechanism, the manual mechanism comprises a matching block, a manual rod and an adjusting structure. When the manual rod is turned downwards from the vertical position to the inclined position, the adjusting structure enables the balancing weight to be close to the matching block so as to reduce the force arm from the balancing weight to the matching block, the force arm from the handle to the matching block is increased so as to reduce the resistance generated when the manual rod rotates downwards, and when the manual rod is turned upwards from the inclined position to the vertical position, the balancing weight is adjusted to be close to the matching block. The adjusting structure enables the balancing weight to be far away from the matching block so as to increase the force arm from the balancing weight to the matching block, so that the force arm from the handle to the matching block is reduced, the resistance generated when the manual rod rotates upwards is reduced under the assistance of the gravity of the balancing weight, and the safety during braking is improved.
本发明涉及驻车制动领域,具体涉及一种防爆无轨胶轮车的驻车制动防护装置。包括密封箱、磁力驱动机构和手动机构;手动机构包括配合块、手动杆和调节结构。在手动杆从竖直位向下转向倾斜位时,调节结构使配重块向配合块靠近以减小配重块到配合块的力臂,使手柄到配合块的力臂增大,以减小手动杆向下转动时的阻力,在手动杆从倾斜位向上转向竖直位时,调节结构使配重块远离配合块而增大配重块到配合块的力臂,使手柄到配合块的力臂减小,在配重块重力辅助下减小在手动杆向上转动时的阻力,提高了制动时的安全性。
