Description
Technical field
The present invention relates to anti-adjustable voltage system, brake system, specifically is a kind of for the anti-down of carriage go-cart and brake composite system.
Background technology
At present, the chip production carriage adopts the go-cart transhipment, the wheel that traditional go-cart comprises vehicle frame and is arranged on the vehicle frame below, vehicle frame is provided with handle, be connected with brake gear on the handle, this device is similar to bicycle brake device, and just principle of work is opposite, needs the grip pressure brake gear that go-cart is moved.The employing of carriage location realizes with the door shield bar in the go-cart, it is inaccurate very easily to produce the carriage location in the transport process, cause carriage to be tumbled, cause serious economy loss, for fear of the generation of this phenomenon, the conventional bracket go-cart arranges anti-down bar usually, but anti-down bar is not only heavy, and cost is higher, and anti-down unreliable.Simultaneously, the brake system of conventional bracket go-cart and anti-adjustable voltage system are relatively independent, make like this and transport personnel's complex operation.
Summary of the invention
The invention provides that a kind of it is higher and safety is not enough to have solved anti-down systems bulky, cost in the past for the anti-down of carriage go-cart and brake composite system, anti-adjustable voltage system separates independent operation with brake system simultaneously, makes the problem of complex operation.
The present invention is achieved through the following technical solutions for the technical solution problem: a kind of for the anti-down of carriage go-cart and brake composite system, comprise brake gear, at least one tilting prevention device and handle, described brake gear is connected with handle by the steel wire tightrope respectively with tilting prevention device, described tilting prevention device comprises driving lever, anti-down briquetting, the self-locking frame, at least three flexible clothes-hooks and housing, one end of described driving lever is connected with handle by the steel wire tightrope, the other end is captiveed joint with anti-down briquetting, described anti-down briquetting is hollow structure, draw-in groove is arranged in the bottom of anti-down briquetting, be provided with at least three through holes in the draw-in groove, described self-locking chord position is in anti-down briquetting, the upper end of self-locking frame is fixed on the top of anti-down briquetting by lock frame spring, described lock frame spring is in compressive state all the time, the middle part of self-locking frame is provided with perforation, described perforation is hardy hole, and aperture is last, macropore is following, described housing is provided with hole clipping, the middle part of anti-down briquetting is provided with guide hole, perforation, hole clipping, the guide hole three is on same straight line, be provided with the self-locking pin in the described guide hole, the self-locking pin is fixed on the hole clipping place of housing by self-locking spring, described self-locking pin comprises the head of a nail and nail post, the diameter of the head of a nail is greater than the hole diameter of perforation and less than the big bore dia of boring a hole, be provided with in the described hole clipping and be exposed at the outer unlock button of housing, described self-locking spring is in extended state all the time, the bottom of described self-locking frame is connected with flexible clothes-hook by the clothes-hook spring, described clothes-hook spring is in compressive state all the time, the axial cross section of described flexible clothes-hook is shaped as " T " font, and flexible clothes-hook is stuck between self-locking frame and the through hole.
Because the effect of lock frame spring, generally, when just tilting prevention device was out-of-run, because the diameter of the aperture of perforation is less than the diameter of the head of a nail of self-locking pin, so the self-locking pin was to be stuck in the aperture of perforation all the time; When carriage is located when inaccurate, anti-down briquetting moves downward in the process, flexible clothes-hook can contact with carriage, carriage impels flexible clothes-hook upward movement and the top self-locking frame that makes progress, the self-locking pin will enter the macropore of perforation from the aperture of perforation then, because the diameter of macropore is greater than the diameter of the head of a nail of self-locking pin, under the pulling force effect of self-locking spring, the self-locking pin is worn to hole clipping, realizes self-locking; During release, inwardly press unlock button, the self-lock pin screw top is gone out hole clipping, the head of a nail of self-locking pin passes the macropore of perforation, and under the effect of lock frame spring, the self-locking frame moves downward then, and the self-locking pin snaps in the aperture of perforation, gets back to initial state.
Described tilting prevention device has two, and two tilting prevention devices are connected with handle by the steel wire tightrope respectively.
Described flexible clothes-hook has a plurality of, and is provided with a plurality of through holes in the bottom draw-in groove of anti-down briquetting, the corresponding flexible clothes-hook of each through hole.
The global shape of described anti-down briquetting is " T " font, and the shape of self-locking frame and size adapt with shape and the size of anti-down briquetting.
Described driving lever is by being bolted on the anti-down briquetting.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) anti-down system architecture of the present invention is comparatively simple, is easy to realize, when the carriage accurate positioning, anti-adjustable voltage system is inoperative; And locate when inaccurate when carriage, the anti-down briquetting of anti-adjustable voltage system moves downward, and carriage is blocked and self-locking, and release is also very simple and convenient, like this, has prevented that carriage from tumbling in transport process, has avoided the economic loss that may cause.
(2) the present invention adopts the mode of brake system and anti-down system interlink, when pressing handle downwards, the carriage go-cart begins mobile and starts anti-adjustable voltage system simultaneously, like this, only need an action can finish two operations, compare brake system and the anti-adjustable voltage system of traditional independent split operation, operate easylier, avoid the generation of slipping up easilier.
(3) the present invention is simple in structure, and is easy to operate, and cost is lower, and practicality is stronger.
