Description

Latch hook device of hook arm vehicle

Technical Field

The utility model relates to hook arm car field is a latch hook device of hook arm car.

Background

The locking on the conventional hook arm vehicle is realized by pushing a locking hook to hook a hook arm or a box by a locking oil cylinder, in any case, the self-unloading function can be completed only by a hook for hooking the box at the back, the horizontal distance between the hook and the hook on the large hook arm is often called as the hook center distance, and the hook center distances of boxes made by different manufacturers are different, so that the universal interchangeability is influenced. The invention removes the hook, changes the hook into a transverse lock box slide rail, does not need the hook center distance any more, and leads the hook arm vehicle to have universality.

Disclosure of Invention

The utility model aims at providing a latch hook device of hook arm car. The hook of the hook box on the two frames on the hook arm vehicle is removed and replaced by the transverse locking device of the utility model which is welded. And operating the hydraulic control valve to tighten the locking oil cylinder to drive the lock tongues at the two ends to retract, inserting the son buckles on the lock tongues into the mother buckles welded on the underframe, locking the two frames, and enabling the large hook arm to rotate only around the middle shafts on the two frames to finish the folding and unfolding work of the box. If the garbage needs to be unloaded, the hydraulic valve is operated to enable the locking oil cylinder to extend outwards to drive the lock tongues at the two ends to move outwards, the snap fastener automatically releases locking, the extending lock tongues press the sliding rail of the box, the box is locked, and the large hook arm, the box and the two frames can only rotate around the rear overturning shaft together to complete the unloading work of the box.

The utility model discloses a realize like this: a latch hook device of a hook arm vehicle comprises an underframe, a left lower hook, a box bottom slide rail, a transverse lock guide rail frame, a left spring bolt, a locking oil cylinder, a right lower hook and a right spring bolt, and is characterized in that the box bottom slide rail is fixed on the underframe, the lower end of the left lower hook is fixed at the left end of the underframe, and the lower end of the right lower hook is fixed at the right end of the underframe; the left spring bolt is connected with the left end of the locking oil cylinder, and the right spring bolt is connected with the right end of the locking oil cylinder; the transverse lock guide rail frame is fixed on the bottom frame.

Due to the adoption of the technical scheme, the distance between the hook centers is removed, and the box slide rail is transversely locked, so that the hook arm vehicle has universality and convenience. Convenient operation, rapidness, safety, simple maintenance, low cost and the like.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a chassis; 2. a left lower hook; 3. a box bottom slide rail; 4. a cross lock guide rail bracket; 5. a left bolt; 6. locking the oil cylinder; 7. a right lower hook; 8. and a right bolt.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

In fig. 1, a sliding rail 3 at the bottom of the box is fixed on an underframe 1, the lower end of the left lower hook 2 is fixed at the left end of the underframe 1, and the lower end of the right lower hook 7 is fixed at the right end of the underframe 1; the left bolt 5 is connected with the left end of the locking oil cylinder 6, and the right bolt 8 is connected with the right end of the locking oil cylinder 6; the transverse lock guide rail frame 4 is fixed on the bottom frame 1.

Referring to fig. 1, this is a normal state of the hook arm vehicle; the locking oil cylinder 6 is tightened, at the moment, the left lock tongue 5 and the right lock tongue 8 are retracted, the sub-buckles on the left lock tongue 5 and the right lock tongue 8 are interlocked with the female buckles on the left lower hook 2 and the right lower hook 7, the whole transverse locking device and the two frames are fixed by the underframe and cannot move, the large hook arm can only rotate around the middle shaft on the two frames, and at the moment, the box is movable and can be hooked up and down.
