The invention provides a walking crane standing braking device which comprises a sliding rail, a wheel carrier and a crane wheel capable of moving along the sliding rail and further comprises a movable rod piece, one end of the movable rod piece is rotationally connected to the side wall of the wheel carrier, and the other end of the movable rod piece is movably connected with a brake used for limiting the crane wheel. The limiting pin piece is arranged on the side wall of the wheel carrier, and the limiting pin piece is used for limiting the rotating position of the movable rod piece along the wheel carrier; the brake comprises a base, a brake block arranged on the limiting face of the base in a sliding mode, and a main pneumatic part arranged in an inner cavity of the base and driven by the brake block. According to the invention, when the crane runs, the movable rod piece is pulled up, the movable rod piece is clamped by the limiting pin piece to prevent the movable rod piece from falling off to influence the running of the crane on the sliding rail, when the crane is in a non-running state, the limiting pin piece relieves the limiting of the movable rod piece, and the position of the brake relative to the movable rod piece can be adjusted by moving the brake; and the brake is adjusted to the lower part of the crane wheel so as to play a braking role.
本发明提供一种行走吊静置制动装置,包括滑轨、轮架以及能够沿滑轨移动的吊机轮,还包括活动杆件,所述活动杆件的一端转动连接在轮架的侧壁,另一端活动连接有用于限定吊机轮的制动器;限位销件,所述限位销件设置在轮架侧壁,所述限位销件用于限定活动杆件沿轮架的转动位置;其中,所述制动器包括底座、滑动设置在底座限位面的制动块、设置在底座内腔且受制动块驱动的主气动部;本发明中,吊机运行时将活动杆件拉起,用限位销件卡住活动杆件,防止活动杆件掉落影响滑轨上的吊机运行,在吊机处于非运行状态时,限位销件解除对活动杆件的限位,可通过移动制动器以调整其相对于活动杆件的位置,并使得制动器调节至吊机轮的下方,以起到制动作用。
