Description
Technical field
The utility model relates to the safety installation on Hoisting Machinery, particularly relates to a kind of band brake of cam mechanism.
Background technique
Break utilizes friction principle to realize mechanism's braking.The friction part of break, with the Brake drum in certain active force hold-down mechanism a certain, produces braking moment, utilizes this braking moment, and the moment that mass of object and inertial force are produced reduces, until two equalising torques, reaches the requirement of speed governing or braking.Higher braking torque often pursued by existing Hoisting Machinery, but for the sake of security, need additional a set of band brake, when there is equipment failure or danger, band brake can make equipment disengaging work, ensure safety, but existing band brake is made up of more part, cost is higher and take sizable space, make installation, maintenance and use all quite inconvenience, and the environment that this band brake uses is general comparatively severe, this makes the maintenance frequency increase, each maintenance takes up room greatly due to it, component are many, make to remove and install workload large, maintenance cost is high.
Model utility content
The purpose of this utility model is the band brake providing a kind of cam mechanism, and to solve band brake additional on existing Hoisting Machinery, take up room the problem large, component are many and maintenance cost is high.
To achieve these goals, the utility model provides following technological scheme: a kind of band brake of cam mechanism, comprise support and be hinged on the disk on support, described disk is fixedly connected with cam, described disk and cam coaxial are arranged, described disk is surrounded with flexible element, brake shoe is provided with in described flexible element, described support is also hinged with fork, described fork comprises the first supporting portion and the second supporting portion, described first supporting portion is provided with guide groove, described second supporting portion is hinged with guide wheel, slide bar is slidably connected in described guide groove, described slide bar pastes to touch to be located on guide wheel, one end of described flexible element is connected with fork, the other end of described flexible element is connected on slide bar, described slide bar is connected with the servo cylinder of SC sigmal control.
The principle of this programme is such: because disk is hinged on support, and disk is fixedly connected with cam, cam can be rotated with the hinge of disk on support, when needs are braked Hoisting Machinery, the servo cylinder of SC sigmal control pulls slide bar, slide bar is located in the guide groove on fork, and paste touch be located on guide wheel, when pulling slide bar, slide bar can move down along guide groove and guide wheel, due to one end of the flexible element on slide bar clutch disk, the other end of flexible element is fixed on fork, slide bar can draw flexible element in moving process, and the tension force of flexible element is increased, brake shoe is provided with in flexible element, brake shoe is under tension to disk and Cam braking, thus realize the braking of system.
The utility model has the advantage of, the band brake of this cam mechanism, adopt cam, fork coordinate flexible element to brake system, its stable equipment operation, structure is simple, volume is little, easy maintenance, and user cost is low, simultaneously flexible to operation.
Preferably, described slide bar is arranged with helical spring, described helical spring is connected with adjusting nut, and adjusting nut coordinates the tension force of the adjustable flexible element of helical spring, can limit in advance, increase applicability to the tension force of system.
Preferably, the middle part of described disk is hinged on support, makes disk rotational steady.
Preferably, described flexible element adopts V band, the conventional component that V band moves for flexible traction, chooses, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the band brake embodiment of a kind of cam mechanism of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Reference character in Figure of description comprises: support 1, disk 2, and cam 3, V is with 4, brake shoe 5, fork 6, guide groove 7, guide wheel 8, slide bar 9, helical spring 10, adjusting nut 11, servo cylinder 12.
As shown in Figure 1, a kind of band brake of cam mechanism, the disk 2 comprising support 1 and be hinged on support 1, the middle part of disk 2 is hinged on support 1, disk 2 is fixedly connected with cam 3, disk 2 and cam 3 are coaxially arranged, disk 2 is surrounded with V band 4, brake shoe 5 is provided with in V band 4, support 1 is also hinged with fork 6, fork 6 comprises the first supporting portion and the second supporting portion, first supporting portion is provided with guide groove 7, second supporting portion is hinged with guide wheel 8, slide bar 9 is slidably connected in guide groove 7, slide bar 9 pastes to touch to be located on guide wheel 8, one end of V band 4 is connected with fork 6, the other end of V band 4 is connected on slide bar 9, slide bar 9 is arranged with helical spring 10, helical spring 10 is connected with adjusting nut 11, slide bar 9 is also connected with the servo cylinder 12 of SC sigmal control.
In the present embodiment, because disk 2 is hinged on support 1, and disk 2 is fixedly connected with cam 3, cam 3 can be rotated with the hinge of disk 2 on support 1, when needs are braked Hoisting Machinery, the servo cylinder 12 of SC sigmal control pulls slide bar 9, slide bar 9 is located in the guide groove 7 on fork 6, and paste touch be located on guide wheel 7, when pulling slide bar 9, slide bar 9 can move down along guide groove 7 and guide wheel 8, due to one end of the V band 4 on slide bar 9 clutch disk 2, the other end of V band 4 is fixed on fork 6, slide bar 9 can draw V band 4 in moving process, and make V be with the tension force of 4 to increase, brake shoe 5 is provided with in V band 4, brake shoe 5 is braked disk 2 and cam 3 under tension, thus realize the braking of system.
Slide bar 9 is arranged with helical spring 10, helical spring 10 is connected with adjusting nut 11, adjusting nut 11 coordinates the tension force of the adjustable V band 4 of helical spring 10, can limit the tension force of system in advance, increase applicability, the middle part of disk 2 is hinged on support 1, makes disk 2 stability of rotation, the conventional component that V band 4 moves for flexible traction, chooses, easy to use.The band brake of this cam mechanism, adopt cam 3, fork 6 coordinate V to be with 4 pairs of systems to brake, its stable equipment operation, structure is simple, volume is little, easy maintenance, and user cost is low, simultaneously flexible to operation.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
