The centrifugal releaser safely-braking system comprises a centrifugal releaser, a braking switch device and a mechanical hydraulic valve, wherein the braking switch device comprises a connecting plate, a swivel, a switch shaft and a switch head; the switch shaft and the connecting plate are fixed on a support plate through a hexagonal head bolt I, a nut and a big washer I; the swivel is sheathed on the switch shaft and simultaneously the upper end of the switch shaft is provided with a hexagonal head bolt II and a big washer II; a threaded hole is formed in the side surface of the swivel, at the same height of a sliding shaft of the centrifugal releaser; at the threaded hole, the switch head is connected to the swivel through a hexagonal thin nut; and a steel ball at the front end of the mechanical hydraulic valve is connected with a hole in the concave arc surface of the swivel. The safely-braking system has the beneficial effects of implementing braking operation automatically when a regulated maximum speed is exceeded, and being simple in structure and convenient to manufacture; and since the radial depth of the concave arc surface of the swivel is greater than the stroke of the mechanical hydraulic valve and the mechanical hydraulic valve has enough braking stroke, an ideal braking effect can be achieved.
Description
Technical field
The utility model relates to a kind of brake system, and a kind of Centrifugal Releaser sure brake system specifically belongs to mechanical control technology field.
Background technology
The Centrifugal Releaser brake system is vital motorcycle safety brake equipment in development of auxiliary transport in coal mines equipment.In development of auxiliary transport in coal mines equipment, be the safety of assurance locomotive and navigating mate, and the steady failure-free operation of locomotive, brake equipment must be set.But at present brake equipment mainly contains emergency braking system unify service braking system.Emergency braking is that locomotive is in operation, and running into suddenly unforeseen circumstances needs when out of service immediately, and a kind of braking model of taking.Service braking refers to that locomotive is in operation when slowing down locomotive running speed in the time of need to doing the operation of interim of short duration parking or descending and a kind of braking model that adopts.When but operation was malfunctioning at the overspeed state or on the ramp, for guaranteeing the normal operation of the former parts of locomotive, it was very necessary and important implementing safety arrestment.
The utility model content
For the problem that above-mentioned prior art exists, the utility model provides a kind of Centrifugal Releaser sure brake system, can automatically implement brake operating when hypervelocity, and simple in structure, easily manufactured.
to achieve these goals, the technical solution adopted in the utility model is: a kind of Centrifugal Releaser sure brake system, comprise Centrifugal Releaser, brake switch apparatus and mechanical-hydraulic valve, brake switch apparatus comprises connecting panel, change, switch shaft and switch head, switch shaft and connecting panel are by the hex bolt I, nut, the large washer I is fixed on stay bearing plate, change is enclosed within on switch shaft, hex bolt II and large washer II are set in the upper end of switch shaft simultaneously, in the side of change and the position of Centrifugal Releaser slide shaft equal height, one tapped bore is set, switch head is connected in change by hexagon thin nut in the position of tapped bore, the steel ball of mechanical-hydraulic valve front end is connected with the hole of change concaved circular cambered surface.
Further, the hole of stay bearing plate and connecting panel connection is trough type.
Further, the concaved circular cambered surface radial depth of change is greater than the stroke of mechanical-hydraulic valve.
Principle of work: when locomotive running speed surpasses the maximum speed of regulation, Centrifugal Releaser is rotated simultaneously, and its slide shaft stretches out, will make its rotation by the toggle switch head like this, result drives the change rotation, make the steel ball of mechanical-hydraulic valve front end eject from the concaved circular cambered surface of change, the concaved circular cambered surface of change just changes position and namely commutates, after commutation the mechanical-hydraulic valve with regard to off-load, locomotive brake.
Beneficial effect is: when surpassing the maximum speed of regulation, automatically implement brake operating, and also simple in structure, easily manufactured.The hole of stay bearing plate and connecting panel connection is designed to trough type, can reach by the movable support plate purpose of adjustable brake switching device position.Due to the stroke of change concaved circular cambered surface radial depth greater than the mechanical-hydraulic valve, the mechanical-hydraulic valve has enough braking distances like this, can reach desirable braking effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, Centrifugal Releaser, 2, stay bearing plate, 3, the mechanical-hydraulic valve, 4, the hex bolt I, 5, nut, 6, large washer I, 7, connecting panel, 8, change, 9, switch shaft, 10, hex bolt II, 11, the large washer II, 12, hexagon thin nut, 13, switch head.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of Centrifugal Releaser sure brake system of the present utility model comprises Centrifugal Releaser 1, brake switch apparatus and mechanical-hydraulic valve 3, and brake switch apparatus comprises connecting panel 7, change 8, switch shaft 9 and switch head 13; Switch shaft 9 and connecting panel 7 are fixed on stay bearing plate 2 by hex bolt I 4, nut 5, large washer I 6, change 8 is enclosed within on switch shaft 9, the bottom of change 8 is by shaft shoulder location, its top has hex bolt II 10 and large washer II 11 to locate, and change 8 has the gap of 0.5mm can guarantee change 8 flexible rotatings with its top and bottom; In the side of change 8 and the position of Centrifugal Releaser 1 slide shaft equal height, one tapped bore is set, one end of switch head 13 is processed into outside thread, the outside thread of switch head 13 is connected in change 8 by hexagon thin nut 12, screw-in length by by-pass cock head 13 screw threads can guarantee can touch switch head 13 when the slide shaft of Centrifugal Releaser 1 in the speed range that limits stretches out, and the steel ball of mechanical-hydraulic valve 3 front ends is connected with the hole of change 8 concaved circular cambered surfaces.
When locomotive running speed surpasses the maximum speed of regulation, Centrifugal Releaser 1 is rotated simultaneously, and slide shaft stretches out, will make its rotation by toggle switch head 13 like this, result just drives change 8 rotations, make the steel ball of mechanical-hydraulic valve 3 front ends eject from change 8 concaved circular cambered surfaces, the concaved circular cambered surface of change 8 just changes position and namely commutates, after commutation mechanical-hydraulic valve 3 with regard to off-load, locomotive brake.
Wherein stay bearing plate 2 can be trough type with the hole of connecting panel 7 connections, so just can reach by movable support plate 2 purpose of adjustable brake switching device position.
The concaved circular cambered surface radial depth of change 8 can be greater than the stroke of mechanical-hydraulic valve 3.As to select mechanical-hydraulic valve 3 strokes are 2.5mm, the concaved circular cambered surface radial depth of change 8 is 3mm, additional travel is 0.5mm, because the steel ball of mechanical-hydraulic valve 3 front ends is connected with hole on change 8 concaved circular cambered surfaces, mechanical-hydraulic valve 3 has enough braking distances like this, thereby can reach desirable braking effect.
