Abstract
A quick rear traction apparatus of a working position apparatus belongs to the technical field of mechanical manufacture and comprises a locking pin, a top outer edge and a lower outer edge, wherein parts such as a pedal transmission shaft, a transmission arm, a fixed shaft, a reverse positioning device, a stepped impact fuze and a fuze locking block are employed for locking the front traction apparatus of the working position apparatus and connecting the same; and the connection is convenient to terminate. The quick rear traction apparatus of the working position apparatus is convenient and quick to operate, capable of effectively reducing the labor intensity and improving the working efficiency, and safe and reliable in performance.
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 generally to adopt station vehicle to transport required parts, by tractor truck moving station utensil car.The rear haulage device of tractor truck and working position apparatus car is to consist of outer, top, outer, bottom and lock pin, on outer, top and outer, bottom, corresponding through hole is arranged, during connection, the protraction headgear of station vehicle is inserted between outer, top and outer, bottom, again lock pin is penetrated to through hole, complete connection.In working process, workman's long-time continuous bends over to operate, inconvenience, and labour intensity is large, and injury accident, easily occur in inefficiency.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of performance safety, easy to operate and can be recessed in working position apparatus and do not affect the quick rear haulage device of working position apparatus that station ability to speak car uses function.
the present invention includes lock pin, outer, top and outer, bottom, there is bottom cavity at below and the rear of outer, bottom, the joist of level is installed on bottom cavity, on the bottom cavity of joist below, horizontal pedal drive shaft is housed, the pedal drive shaft outside is equipped with opens pedal, transmission arm is installed on pedal drive shaft, transmission arm is by forearm, postbrachium and lower locking block form, lower locking block top rear side has block, on pedal drive shaft, be wound with the rising torsion spring, horizontal anchor shaft is housed on the bottom cavity between joist and pedal drive shaft, reverse locating device is installed on anchor shaft, reverse locating device consists of upper locking block and linked block, upper locking block is corresponding with lower locking block apical position, anchor shaft is wound with the interlock reduction torsion spring, in the middle of the joist front end, have the slot of fore-and-aft direction in place, the both sides at joist rear portion have pilot hole, the staged percussion fuze is installed above joist, staged percussion fuze trailing flank is topped bar and is got out of a predicament or an embarrassing situation, the retracing spring of horizontal fore-and-aft direction is housed between the bottom of getting out of a predicament or an embarrassing situation and bottom cavity, guide groove is arranged at the bottom of staged percussion fuze, the slot that the linked block of reverse locating device passes joist enters in guide groove, the fuse locking block is arranged between the bottom cavity at staged percussion fuze and its rear portion, fuse locking block both sides are connected with respectively downward guidepost, guidepost passes pilot hole, bottom is corresponding with the postbrachium position of transmission arm.While between station vehicle and tractor truck and station vehicle and station vehicle, being connected, the protraction headgear of station vehicle inserts between the outer, top and outer, bottom of rear haulage device, clash into the staged percussion fuze, the staged percussion fuze moves backward, the guide groove edge drives linked block, reverse locating device is rotated counterclockwise, upper locking block and lower locking block break away from, pedal drive shaft rotates counterclockwise under the effect of rising torsion spring, forearm by transmission arm rises lock pin, the locking protraction headgear, simultaneously, the combination of topping bar of fuse locking block and staged percussion fuze, tension force effect due to retracing spring, the staged percussion fuze moves forward, the fuse locking block breaks away from tops bar, now the postbrachium of transmission arm moves down, fuse locking block and guidepost free fall, on the fuse locking block drops on and gets out of a predicament or an embarrassing situation, block the staged percussion fuze, make the fuse locking block pin securely the staged percussion fuze, thereby while guaranteeing to occur protraction headgear shock staged percussion fuze situation in tractor truck and station vehicle driving process, the staged percussion fuze is in the lock state.When the protraction headgear of station vehicle need to break away from the rear haulage device, trample downwards and open pedal, pedal drive shaft overcomes and rises the torsion spring application force and clockwise rotate, lock pin falls, rear wall holds up guidepost, the fuse locking block rises to leave and gets out of a predicament or an embarrassing situation, and simultaneously, upper locking block is combined with lower locking block at the locking block return that makes as the used time of interlock reduction torsion spring.
On the outer, top, strong magnet is housed, lock pin is iron material.After lock pin rose the locking protraction headgear, if the rising torsion spring lost efficacy, lock pin, because strong magnet attracts, still can lock protraction headgear, and, after trampling and opening pedal, did not affect lock pin and break away from the rear haulage device.
The present invention is easy to operate, quick, can effectively reduce labour intensity, increases work efficiency, and performance safety is reliable.
