Description
Technical field
The present invention relates to anti-adjustable voltage system, brake system, specifically a kind of for the anti-down of bracket cart and brake composite system.
Background technology
At present, chip production bracket adopts go-cart transhipment, traditional go-cart comprises vehicle frame and is arranged on the wheel below vehicle frame, vehicle frame is provided with handle, handle is connected with brake gear, this device is similar to bicycle brake device, and just principle of work is contrary, needs grip pressure brake gear that go-cart just can be made to move.Bracket location adopts and realizes with the door shield bar in go-cart, bracket location is very easily produced inaccurate in transport process, bracket is caused to be tumbled, cause serious economic loss, in order to avoid the generation of this phenomenon, 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.Meanwhile, brake system and the anti-adjustable voltage system of conventional bracket go-cart are relatively independent, make transport personnel complex operation like this.
Summary of the invention
The invention provides a kind of for the anti-down of bracket cart and brake composite system, solve anti-down systems bulky in the past, cost is higher and safety inadequate, anti-adjustable voltage system separates independent operation with brake system simultaneously, makes the problem of complex operation.
The present invention is that technical solution problem is achieved through the following technical solutions: a kind of for the anti-down of bracket cart and brake composite system, comprise brake gear, at least one tilting prevention device and handle, described brake gear is connected with handle respectively by steel wire tightrope with tilting prevention device, described tilting prevention device comprises driving lever, anti-down briquetting, self-locking frame, at least three flexible clothes-hooks and housing, one end of described driving lever is connected with handle by steel wire tightrope, the other end is fixedly connected with anti-down briquetting, described anti-down briquetting is hollow structure, draw-in groove is arranged in the bottom of anti-down briquetting, at least three through holes are provided with in 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 upper, macropore under, described housing is provided with hole clipping, the middle part of anti-down briquetting is provided with guide hole, perforation, hole clipping, guide hole three on the same line, self-locking pin is provided with in described guide hole, 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 is less than the diameter macropores of perforation, the unlock button be exposed at outside housing is provided with in described hole clipping, 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 clothes-hook spring, described clothes-hook spring is in compressive state all the time, the axial cross section shape of described flexible clothes-hook is " T " font, flexible clothes-hook is stuck between self-locking frame and through hole.
Due to the effect of lock frame spring, under normal circumstances, time namely tilting prevention device is out-of-run, the diameter due to the aperture of perforation is less than the diameter of the head of a nail of self-locking pin, and therefore self-locking pin is be stuck in the aperture of perforation all the time; When bracket location is inaccurate, anti-down briquetting moves downward in process, flexible clothes-hook can contact with bracket, bracket impels flexible clothes-hook upward movement and upwards pushes up self-locking frame, then self-locking pin will enter the macropore of perforation from the aperture of perforation, and the diameter due to 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, self-locking pin is worn to hole clipping, realizes self-locking; During unblock, inwardly press unlock button, self-lock pin screw top is gone out hole clipping, the head of a nail of self-locking pin is through the macropore of boring a hole, and then under the effect of lock frame spring, self-locking frame moves downward, and self-locking pin snaps in the aperture of perforation, gets back to initial state.
Described Anti-inversion is equipped with two, and two tilting prevention devices are connected with handle respectively by steel wire tightrope.
Described flexible clothes-hook has multiple, and is provided with multiple through hole 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 shape and the size of the shape of self-locking frame and size and anti-down briquetting adapt.
Described driving lever is bolted on 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, and when bracket accurate positioning, anti-adjustable voltage system is inoperative; And when bracket location is inaccurate, the anti-down briquetting of anti-adjustable voltage system moves downward, bracket is blocked and self-locking, unlock also very simple and convenient, like this, prevent bracket to tumble in transport process, avoid 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, bracket cart starts mobile and starts anti-adjustable voltage system simultaneously, like this, only need an action can complete two operations, compare the brake system of traditional independent split operation and anti-adjustable voltage system, operate easier, more easily avoid the generation of slipping up.
(3) structure of the present invention is simple, and easy to operate, cost is lower, and practicality is stronger.
