Abstract
The invention discloses a brake device of an amplitude-variable winch, which comprises a base, a reel, a motor, a speed reducer and a brake, wherein the brake is arranged in the speed reducer and is used for braking, the base is connected with a wall shelf, the motor is arranged on the wall shelf, and the output end of the motor is connected with the speed reducer; an output shaft of the speed reducer is connected with a revolving shaft of the reel, a ratchet is fixedly arranged on the revolving shaft of the reel, a mounting plate is fixedly connected with the base, a pallet is arranged on the mounting plate by a pallet shaft in a rotating way, one end of the pallet is matched with the ratchet, the other end of the pallet is hinged with an expansion link, and the expansion link is driven by a driving device. According to the brake device of the amplitude-variable winch, a ratchet-pallet mechanism is additionally provided to match the brake in the original speed reducer so as to form the double brake, so that the safety of a crane is greatly enhanced, and the accidents can be efficiently prevented from happening. The brake device is simple in structure and easy to realize.
Description
Technical field
The present invention relates to a kind of brake equipment, relate in particular to a kind of brake equipment of span winch.
Background technology
Span winch is to have storage rope ability, is used for making carrying or nonbearing suspension rod luffing and keeps the winch of its position.The span winch of existing hoisting crane only is provided with drg usually in reductor, yet this kind structure in case the grave accident that arm falls easily occurs the brake failure in the reductor, has certain potential safety hazard.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of brake equipment of span winch is provided, only drg is set in reductor with the span winch that solves existing hoisting crane, have the problem of potential safety hazard.
The objective of the invention is to be achieved through the following technical solutions:
A kind of brake equipment of span winch, comprise reel, motor, reductor and be arranged at the drg that is used for braking in the reductor, described motor is installed on the wall frame, and the mouth of motor links to each other with reductor, the output shaft of described reductor links to each other with the rotating shaft of reel, be installed with ratchet in the rotating shaft of described reel, be fixedly connected with adapter plate on the described wall frame, on the described adapter plate by the rotating ratchet that is provided with of pawl axis, one end of described ratchet matches with ratchet, its other end and expansion link are hinged, and described expansion link is driven by actuating device.
Further, described actuating device is oil cylinder.
Beneficial effect of the present invention is that the brake equipment of described span winch cooperates the drg in original reductor by setting up ratchet and pawl arrangement, form double brake, greatly increased the safety of hoisting crane, effectively prevent the generation of safety misadventure, simple in structure, be easy to realize.
Description of drawings
Fig. 1 is the structural representation of the brake equipment of a kind of span winch of the present invention;
Fig. 2 is that the A of brake equipment of a kind of span winch shown in Figure 1 is to schematic diagram.
Among the figure:
1, reductor; 2, reel; 3, motor; 4, wall frame; 5, ratchet; 6, oil cylinder; 7, ratchet; 8, pawl axis; 9, adapter plate.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to Figure 1 and Figure 2, in the present embodiment, a kind of brake equipment of span winch, comprise reel 2, motor 3, reductor 1 and be arranged at the drg that is used for braking in the reductor 1, described motor 3 is installed on the wall frame 4, and the mouth of motor 3 links to each other with reductor 1, the output shaft of described reductor 1 links to each other with the rotating shaft of reel 2, be installed with ratchet 5 in the rotating shaft of described reel 2, be fixedly connected with adapter plate 9 on the described wall frame 4, on the described adapter plate 9 by the pawl axis 8 rotating ratchets 7 that are provided with, one end of described ratchet 7 matches with ratchet 5, its other end and expansion link are hinged, and described expansion link is driven by actuating device, and described actuating device is oil cylinder 6.
As shown in Figure 2, when the present invention used, oil cylinder 6 drove expansion link, thereby the right-hand member that drives ratchet 7 moves downward, and rotates around pawl axis 8 clockwise directions, so that the left end upward movement of ratchet 7, thereby block ratchet 5 brakings, safe and reliable, increased the safety of hoisting crane.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
