Abstract
The invention belongs to a rapid rear tractor of a working position instrument, and belongs to the technical field of mechanical manufacturing. The rapid rear tractor comprises a lock pin, a top outer edge and a lower outer edge, wherein a front tractor of the working position instrument is locked, connected and conveniently opened through components such as a pedal transmission shaft, a transmission arm, a reverse positioning device, a step-shaped collision fuse and a fuse locking block. The rapid rear tractor is convenient and rapid to operate, the working intensity can be effectively alleviated, the working efficiency can be improved, and the safe and reliable performance can be achieved.
Description
Technical field
The invention belongs to machinery manufacturing technology field, relate to a kind of connecting device.
Background technology
The workshop of manufacturing enterprise is usually employing station vehicle and transports required parts, by tractor moving station utensil car.The rear haulage device of tractor and working position apparatus car is to be made up of outer, top, outer, bottom and lock pin, outer, top and outer, bottom have the through hole of correspondence, during connection, the protraction headgear of station vehicle is inserted between outer, top and outer, bottom, again lock pin is penetrated through hole, complete to connect.In work process, workman bends over to operate for a long time continuously, it has not been convenient to, and labor intensity is big, inefficiency, and injury accident easily occurs.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of performance safety, easy to operate and can cave in do not affect in working position apparatus station ability to speak car use function working position apparatus Quick rear traction.
The present invention includes lock pin, outer, top and outer, bottom, there is bottom cavity at lower section and the rear of outer, bottom, bottom cavity is provided with the backing board of level, equipped with horizontal pedal drive shaft on bottom cavity below backing board, it is provided with outside pedal drive shaft and opens pedal, pedal drive shaft is provided with transmission arm, transmission arm is by forearm, postbrachium and lower clamping block are constituted, block is had on rear side of lower clamping block top, pedal drive shaft is wound with rising torsion spring, equipped with horizontal fixing axle on bottom cavity between backing board and pedal drive shaft, fixing axle is provided with reverse locating device, reverse locating device is made up of upper clamping block and linked block, upper clamping block is corresponding with lower clamping block apical position, fixing axle is wound with gearing reduction torsion spring, middle, backing board front end has the slot of fore-and-aft direction, the both sides at backing board rear portion have pilot hole, backing board is installed above staged percussion fuze, staged percussion fuze trailing flank is topped bar and is got out of a predicament or an embarrassing situation, equipped with the back-moving spring of horizontal fore-and-aft direction between bottom and the bottom cavity got out of a predicament or an embarrassing situation, gathering sill is arranged at the bottom of staged percussion fuze, the linked block of reverse locating device enters in gathering sill through the slot of backing board, fuse clamping block is had between staged percussion fuze and the bottom cavity at its rear portion, fuse clamping block both sides are connected to downward lead, lead traverse pilot hole, bottom is corresponding with the postbrachium position of transmission arm.When being connected between station vehicle with tractor and station vehicle with station vehicle, the protraction headgear of station vehicle inserts between outer, top and the outer, bottom of rear haulage device, clash into staged percussion fuze, staged percussion fuze is moved rearwards by, gathering sill edge drives linked block, reverse locating device is made to rotate counterclockwise, upper clamping block departs from lower clamping block, pedal drive shaft rotates counterclockwise under rising torsion spring effect, lock pin is made to rise by the forearm of transmission arm, locking protraction headgear, simultaneously, the combination of topping bar of fuse clamping block and staged percussion fuze, tension force effect due to back-moving spring, staged percussion fuze moves forward, fuse clamping block departs from tops bar, now the postbrachium of transmission arm moves down, fuse clamping block and lead free-falling, on fuse clamping block drops on and gets out of a predicament or an embarrassing situation, block staged percussion fuze, fuse clamping block is made to pin staged percussion fuze securely, thus when ensureing to occur protraction headgear to clash into staged percussion fuze situation in tractor and station vehicle driving process, staged percussion fuze is in the lock state.When the protraction headgear of station vehicle needs to depart from rear haulage device, trample downwards and open pedal, pedal drive shaft overcomes a liter torsion spring active force to rotate clockwise, lock pin falls, rear wall is directed to column bracket and rises, fuse clamping block is lifted off getting out of a predicament or an embarrassing situation, and meanwhile, upper clamping block makes clamping block return be combined with lower clamping block when interlocking the effect of reduction torsion spring.
Equipped with strong magnet on outer, top, lock pin is iron material.After lock pin rises locking protraction headgear, losing efficacy if up torsion spring, lock pin attracts due to strong magnet, remains to locking protraction headgear, and after trampling and opening pedal, does not affect lock pin and depart from rear haulage device.
The present invention is easy to operate, quick, it is possible to effectively reduce labor intensity, improves work efficiency, and performance safety is reliable.
