The novel hydraulic cylinder can improve the working efficiency of machinery on soft soil, and particularly can reduce noise and vibration and improve the operation feeling of a driver when the novel hydraulic cylinder is used for replacing a steel track. In the prior art, as shown in fig. 1, iron teeth 11 are embedded inside a rubber track along the length direction of the rubber track, the iron teeth 11 comprise guide tooth tips 12 and wing surfaces 13, a large gap is formed between guide surfaces of adjacent iron teeth 11, the guide surfaces are separated from each other, and the iron teeth 11 are easily influenced by external force to slide during the running of the track, particularly during the turning process, due to unbalanced absorption and conversion of driving force, so that the track is derailed. In addition, as shown in fig. 2 and fig. 3, during rapid acceleration or rapid braking, the steel wire bears a force greater than the self weight of the machine, the stress is suddenly increased, and the steel wire is broken, and the steel teeth 11 are easy to roll over along with the change of the vehicle displacement, so that the steel wire 14 is cut off by the iron teeth 11, and the service life of the track is seriously affected. As is known to all, the rubber crawler belt has a large ground contact area, and the strong friction force between the rubber crawler belt and the ground causes that the crawler belt is easy to deform or fall off in the turning process of the tracked vehicle.

Disclosure of Invention

The utility model discloses a hinge type track iron teeth, including the iron teeth unit that vertically connects gradually along more than two, arbitrary iron teeth unit side all is provided with two iron teeth along horizontal interval, arbitrary iron teeth unit bottom all is provided with two opening decurrent draw-in grooves along horizontal interval, iron teeth unit between two draw-in grooves constitutes a drive block, all transversely be provided with a first through-hole along respectively in arbitrary drive block, transversely run through draw-in groove and iron teeth unit about the first through-hole, the top of iron teeth unit is provided with quantity the same with the draw-in groove, the fixture block that position and draw-in groove correspond, all transversely be provided with a second through-hole along respectively in arbitrary fixture block, the fixture block of arbitrary iron teeth unit is equallyd divide and is do not inserted in the draw-in groove of its adjacent iron teeth unit, arbitrary drive block all inserts respectively between two fixture blocks of establishing its adjacent iron teeth unit, the first through-hole of iron teeth unit and the coaxial setting of the second through-hole of adjacent iron teeth unit, and wear to be equipped with a bolt, two adjacent iron teeth units pass through the bolt is articulated.

Further, the diameter of the first through hole is equal to the diameter of the second through hole.

Compared with the prior art, the utility model, its effect is positive and obvious. The utility model discloses a bolt traversing adjacent drive block's first through-hole and the second through-hole of fixture block realize rigid connection, form similar chain state, can replace the steel wire completely, reduce and take the risk absolutely, the mutual restrictive nature between the iron teeth unit has improved the transverse rigidity of track, avoids the steel wire by the risk that the iron teeth of skew cut off, has significantly reduced the iron teeth and has slided the quality risk that brings the track derail.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments, but the present invention is not limited to this embodiment, and the protection scope of the present invention should be included in all similar structures and similar variations thereof. The utility model provides an upper and lower, preceding, back, left and right equidirectional use only for the description convenience, it is not right the technical scheme's of the utility model restriction.

As shown in fig. 4-8, the utility model discloses a hinge type track iron teeth, including the iron teeth unit 1 that vertically connects gradually along more than two, any one iron teeth unit 1 side all is provided with two iron teeth 2 along horizontal interval, any one iron teeth unit 1 bottom all is provided with two draw-in grooves 3 that open side down along horizontal interval, iron teeth unit 1 between two draw-in grooves 3 constitutes a drive block 4, all transversely be provided with a first through-hole 5 in any one drive block 4 separately, transversely run through draw-in groove 3 and iron teeth unit 1 about first through-hole 5, the top of iron teeth unit 1 is provided with quantity the same with draw-in groove 3, the position is the fixture block 6 that corresponds with draw-in groove 3, all transversely be provided with a second through-hole 7 in any one fixture block 6 separately, fixture block 6 of any one iron teeth unit 1 equally divide and do not insert in the draw-in groove 3 of its adjacent iron teeth unit 1, any one drive block 4 all inserts between two fixture blocks 6 of its adjacent iron teeth unit 1 separately, the first through-hole 5 of iron teeth unit 1 and the coaxial second through-hole 7 of adjacent iron teeth unit 1, the bolt setting up two articulated bolt units 8 and pass through two bolt units 1.
