Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 4, a kind of handcart type breaker fall-proofing device that the utility model discloses, comprises bearing 1, drive block 2, back-moving spring 3, lockweight 4 and is arranged at the drive pin 5 in travel mechanism 10.
Drive block 2 is movably arranged in bearing 1, and on drive block 2, is provided with the back-moving spring 3 that makes its reset.In the present embodiment, on bearing 1, form the first lower limit hole 11 and the second lower limit hole 12, drive block 2 forms and is T-shape by wide portion 21 with narrow portion 22, narrow portion 22 is successively through the first lower limit hole 11 and the second lower limit hole 12, back-moving spring 3 is arranged on narrow portion 22, and wide portion 21 is limited on the first lower limit hole 11.
Lockweight 4 is movably arranged in bearing 1, and one end is resisted against drive block 2, and the other end is relative with the lockhole 201 of handcart type breaker crossbeam 20.In the present embodiment, form the first upper limit hole 13 and the second upper limit hole 14 on bearing 1, wherein, the second upper limit hole 14 is relative with lockhole 201, and the bore in the first upper limit hole 13 is greater than the bore in the second upper limit hole 13; Accordingly, lockweight 4 is formed and is down T-shape with narrow portion 42 by wide portion 41, and wide portion 41 is movable in the first upper limit hole 13, and narrow portion 42 is movable in the second upper limit hole 14.Because the bore in the first upper limit hole 13 is greater than the bore in the second upper limit hole 13, make lockweight 4 can not depart from bearing 1.
