Abstract
The utility model discloses a novel centrifugal releaser. By means of the principle of centrifugal force, a sliding block is subject to the centrifugal force, the sliding block slides to the inner wall of the centrifugal releaser, when the centrifugal force is greater than the spring force, a sliding shaft which is connected with the sliding block stretches out, when the centrifugal force is smaller than the spring force, the sliding shaft which is connected with the sliding block draws back. Compared with other unloading protecting mechanisms, the novel centrifugal releaser is simple in structure, compact in size, flexible and reliable, low in cost, convenient in maintenance and low in requirement on the material wear resistance, thereby avoiding unnecessary economic waste caused by the high requirement on the material.
Description
Technical field
The utility model relates to the mine equipment field, particularly a kind of novel centrifugal releaser.
Background technology
Centrifugal Releaser is a vital motorcycle safety brake equipment in the auxiliary conveying equipments of colliery." safety regulations in coal mine " the 378th regulation: " hauling engine of monorail hoist, road railer, rack rails car and railless free-wheeled vehicle and driving winch should have the failure-free brake system." therefore, locomotive can be implemented safety arrestment automatically when driving over the speed limit or operation is malfunctioning on the ramp extremely important.The braking effect of brake equipment is related to the safety problem of people and Che, and it is not perfect to lose the fender guard that carries the aspect in the auxiliary conveying equipments of present domestic colliery, and the protection effect is also troubling.
In the auxiliary conveying equipments of colliery, be assurance locomotive and mental awareness at present, and the steady failure-free operation of locomotive, brake equipment generally be provided with.Centrifugal Releaser is to use maximum safety speed-limit devices in the present coal mine machinery, but the existing design form mainly is the centrifugal friction speed-limited type.Because constantly wearing and tearing between interactional part are just relatively harsher to the resistance to abrasion requirement of part material so, also can cause the speed limit inefficacy when serious.Therefore, improve Centrifugal Releaser version and just seem very necessary.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of novel centrifugal releaser is provided.
In order to achieve the above object; A kind of novel centrifugal releaser that the utility model provides; Said novel centrifugal releaser upper cover plate is secured together through 4 cross recess fillister head screws and shell, and then through 4 cross recess fillister head screws and 1 straight pin and the turning cylinder composition rotator assembly that links together; Slide shaft vertically runs through an end of turning cylinder, and the through hole when keeping slide relative, shell to be provided with slide shaft stretching out with turning cylinder; The slide block I is connected with slide shaft through taper pin with internal thread, slides with slide shaft; The slide block II directly is enclosed within on the slide shaft, on slide shaft, slides; One side of slide block I and slide block II is respectively equipped with spring, and said spring housing is located on the slide shaft, and an end of spring is resisted against outer casing inner wall.
Wherein, said slide shaft vertically runs through the turning cylinder place and is provided with sintered metal powder bearing.
Wherein, be arranged with adjusting pad on the said turning cylinder, said adjusting pad is fixed in outer casing inner wall through straight pin, and the outer wall of slide block I and slide block II is the one-level ledge structure, and said adjusting pad one side is stuck on the ledge structure, with the amount of compression of regulating spring.
Beneficial effect: a kind of novel centrifugal releaser structure that the utility model provides; The utilization centrifugal principle, slide block receives centrifugal action, and slide block slides to the Centrifugal Releaser inwall; When centnifugal force during greater than spring force; The slide shaft that links to each other with slide block stretches out, and when centnifugal force during less than spring force, the slide shaft that links to each other with slide block is return.Lose to carry protection mechanism with other and compare, not only simple in structure, compact dimensions, flexibility and reliability, cost be low, safeguard aspect but also less demanding to material wear ability, avoided causing owing to material requirements is too high unnecessary economic waste.
Description of drawings
Fig. 1 the utility model novel centrifugal releaser constructional drawing.
Accompanying drawing sign: 1, cross recess fillister head screw; 2, spacer; 3, upper cover plate; 4, slide block II; 5, straight pin; 6, sintered metal powder bearing; 7, turning cylinder; 8, taper pin with internal thread; 9, adjusting pad; 10, cross recess fillister head screw; 11, slide block I; 12, slide shaft; 13, spring; 14, shell.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
The primary member of the novel centrifugal releaser of present embodiment is centrifugal slide block I 11, and Fig. 1 is Structure of Centrifugal Releaser figure, mainly contains compositions such as rotator assembly, slide block, slide shaft, connection strut member, adjusting pad, spring.Upper cover plate 3 is secured together through 4 cross recess fillister head screws 1 and shell 14, and then through 4 cross recess fillister head screws 10 and 1 straight pin 5 and the turning cylinder 7 composition rotator assembly that links together.
Slide block I 11 connects with slide shaft 12 through taper pin with internal thread 8 mutually, slides with slide shaft 12; Slide block II 4 directly is enclosed within on the slide shaft 12, on slide shaft 12, slides.This structure adopts 2 springs 13 to come limit slippage axle 12 when to stretch out in addition, and adjusting pad 9 is used for the amount of compression of regulating spring 13, the extension elongation of shell 14 limit slippage axles 12.When slide shaft 12 stretches out, guarantee that by 2 sintered metal powder bearing 6 in the structure itself and 7 of turning cylinders have good suitable motion.
At turning cylinder 7 rotating speeds hour, compression spring 13 is pushed down slide block, prevents that slide shaft 12 from stretching out; When turning cylinder 7 rotating speeds arrived certain value, slide block I 11 was similar to the circular cone pendulum, produces centrifugal phenomenon, drove slide shaft 12 compression spring together, and slide shaft 12 is stretched out.Turning cylinder 7 changes soon more, and slide shaft 12 outside miles of relative movement are big more, and promptly the size of slide shaft 12 outside miles of relative movement and the rotation speed of turning cylinder 7 have corresponding relation.Startup was installed in its control brake of stretching out direction " switch " when slide shaft 12 stretched out, thereby reached the purpose that triggers the safety arrestment response.
Above content is the further explain that combines optimal technical scheme that the utility model is done, and can not assert that the practical implementation of utility model only limits to these explanations.Under the utility model, the those of ordinary skill of technical field, under the prerequisite of the design that does not break away from the utility model, can also make simple deduction and replacement, all should be regarded as the protection domain of the utility model.
