Abstract
The utility model discloses a braking device for a luffing winch. The braking device comprises a base, a winding drum, a motor, a speed reducer and a brake, wherein the brake is arranged in the speed reducer, and is used for braking; a wall shelf is connected to the base; the motor is arranged on the wall shelf; the output end of the motor is connected with the speed reducer; an output shaft of the speed reducer is connected with a rotating shaft of the winding drum; a ratchet is fixedly arranged on the rotating shaft of the winding drum; a mounting plate is fixedly connected to the base; a pawl is arranged on the mounting plate through a pawl shaft in a rotating way; and one end of the pawl is matched with the ratchet, and the other end of the pawl is hinged with a telescopic rod which is driven by a driving device. According to the braking device for the luffing winch, a ratchet-pawl mechanism is additionally arranged, and is matched with the brake in the conventional speed reducer to form dual braking, so that the safety of a crane is greatly improved, and safety accidents are effectively prevented; and the braking device is simple in structure and easy to implement.
Description
Technical field
The utility model relates to a kind of brake equipment, relates 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 reductor, has certain potential safety hazard.
The utility model content
The purpose of this utility model is for the problems referred to above, and a kind of brake equipment of span winch is provided, and only drg is set in reductor with the span winch that solves existing hoisting crane, has the problem of potential safety hazard.
The purpose of this utility model 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 reductor, described motor is installed on the wall frame, and the mouth of motor is connected with reductor, the output shaft of described reductor is connected with the rotating shaft of reel, be installed with ratchet in the rotating shaft of described reel, be fixedly connected with adapter plate on described wall frame, on 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.
The beneficial effects of the utility model are that the brake equipment of described span winch coordinates 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 utility model;
Fig. 2 is that the A of brake equipment of a kind of span winch shown in Figure 1 is to schematic diagram.
In 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 illustrate the technical solution of the utility model 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 reductor 1, described motor 3 is installed on wall frame 4, and the mouth of motor 3 is connected with reductor 1, the output shaft of described reductor 1 is connected 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 described wall frame 4, on described adapter plate 9 by the rotating ratchet 7 that is provided with of pawl axis 8, one end of described ratchet 7 matches with ratchet 5, its other end and expansion link are hinged, described expansion link is driven by actuating device, described actuating device is oil cylinder 6.
As shown in Figure 2, when the utility model 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, makes 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 utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
