Abstract
The utility model discloses a heavy type quick back tractor which is characterized by comprising a main shell body, a pedal mechanism, a pull hook, a top block and a mousing-hook linkage self-locking mechanism, wherein the pedal mechanism and the top block provided with a clamping piece are installed on the main shell body. The pedal mechanism comprises pedals and a transmission shaft which is installed in a shaft hole of the main shell body. The transmission shaft is provided with a torsional spring. The pull hook is connected in the middle of the transmission shaft in a welding mode. The mousing-hook linkage self-locking mechanism is connected below the pedal mechanism. Compared with the prior art, the heavy type quick back tractor has the advantages of being simple in structure and convenient to operate. Working efficiency is greatly improved, damages of product parts are reduced, a hook can be automatically locked, the hook can be prevented from falling, labor intensity of workers is greatly reduced through pedal unhooking, and working efficiency is improved.
Description
Technical field
The utility model relates to the quick rear haulage device of a kind of heavy type, and the working position apparatus of be widely used in automobile industry and each parts supplier, manufactured parts being transported and logistics department's transportation part uses directly is connected to each other.
Background technology
At present, the heavy rear haulage device fast that uses on market mostly is M/C, and complex operation, and volume is heavier, and physical construction leaks outside, and easily is subject to outside destroy and causes product failure, utensil is broken off relations cause damage of product.
The utility model content
The utility model is in order to solve above-mentioned deficiency, to provide a kind of heavy type quick rear haulage device.
Above-mentioned purpose of the present utility model realizes by following technical scheme: the quick rear haulage device of a kind of heavy type, it is characterized in that: comprise main casing, footstep mechanism, traction hook, jacking block and lock hook linkage self-locking mechanism, described footstep mechanism, jacking block are provided with card, and be installed on main casing, described footstep mechanism comprises pedal and transmission shaft, transmission shaft is arranged in the axis hole of main casing, and be provided with torsion spring, the traction hook is welded in transmission shaft middle part, and lock hook linkage self-locking mechanism is connected in the footstep mechanism below.
Described pedal comprises left-hand tread plate and right-hand tread plate.
Described lock hook linkage self-locking mechanism comprises locking plate and pipe link, described locking plate and pipe link welding, and locking plate is connected in the pedal below by steel pin, and by the hole sponson locking plate on pedal.
Principle of work of the present utility model: when depressing pedal gear, the locking plate medial extremity of lock hook linkage self-locking mechanism breaks away from main casing to top offset, no longer withstand main casing, traction hook Unscrew, jacking block outwards ejects, and the card on jacking block blocks hauling hook and footstep mechanism; When eye hitch clashes into jacking block, jacking block is stressed to affect and shrinks, pedal gear and traction hook are subjected to the torsion spring effect, returning quickly namely draws hook and gets back to closure state, at this moment, lock hook linkage self-locking mechanism is affected by gravity tenesmus, make the locking plate medial extremity again withstand main casing, simultaneously, pipe link can prevent that drawing hook comes off.
The utility model compact conformation, and added lock hook linkage self-locking mechanism, self-locking device adopts gravity, under hook Operating In Persistent Current Mode state, self-locking device is affected by gravity automatically and falls open, and wants to make hook to open, must adopt foot-operated release, the phenomenon even torsion spring fatigue failure, fracture can not broken off relations is yet fundamentally got rid of unhook hidden danger.
The utility model advantage compared with prior art is: the utility model is simple in structure, and simple operation is increased work efficiency greatly, reduce the damage of product parts, automatic latch hook, lock hook, foot-operated decoupling device has reduced workman's labour intensity greatly, has improved work efficiency.
