Description
Technical field
The present invention relates to power-assisted trailer field, more particularly to one kind unloading power-assisted trailer.
Background technology
Recently as the fast development of delivery industry, people increasingly increase for the carrying requirement of express delivery, fast to strengthen
Pass website goods carrying it is horizontal with efficiency, it is necessary to promote using new handbarrow and commercially and application, for such as
What improve handling efficiency, it is necessary to existing handbarrow is carried out in terms of following four it is perfect, 1, need to facilitate the handling of goods；
2nd, the bearing capacity of raising instrument is needed；3rd, instrument is allowed to possess the function of power-assisted；The stability of instrument when the 4th, needing to improve carrying
To deal with bumpy sections；5th, solve the problems, such as that delivery vehicle speed difference occurs when turning.
The content of the invention
In order to solve above-mentioned problem, the present invention provides a kind of unloading power-assisted trailer, and the unloading power-assisted trailer is ingenious
Combine guide-bar mechanism and wireline pulley mechanism, the gravitional force of goods is effectively converted into dynamic when Hand pulling vehicle is advanced
Can, its support board, which can be realized, to be tilted and can be slided on top panel so that this car possesses good handling Adapter Property, trailing wheel
Structure design causes trailer to possess buffering, the function of differential, product strong applicability of the present invention is designed more than, using just
Victory is stable, convenient, for up to this purpose, the present invention provides a kind of unloading power-assisted trailer, including baffle plate, slip top panel, self-locking
Frame, gear regulating block, hand lever, rotatable hand handle, gear coordinating block, chassis, universal wheel, main support shaft, main step bearing seat, pressure
Bar axle, depression bar, movable pulley axle, neck roller, movable pulley, trailing wheel, whirlpool spring, wire reel, brake disc, brake, damping
Spring, self-locking frame girder, trailing wheel main shaft and steel wire, there are 2 bar-shaped troughs, two supports of the baffle plate on the slip top panel
Bar-shaped trough through slip top panel is connected with upside above self-locking frame, and the slip top panel is described on self-locking frame
Self-locking frame girder passes through self-locking frame, and there is main support shaft the self-locking frame girder lower end, and respectively there is a master at the main support shaft both ends
Supporting shaft holder, the main step bearing seat lower end are fixed on front side of chassis, have gear coordinating block, institute above the chassis front end
State gear regulating block by connecting shaft with gear coordinating block to be connected, the hand lever lower end passes through rotating shaft and gear regulating block upper end phase
Even, the hand lever upper end is connected with rotatable hand handle, and the chassis front end down either side is provided with two by fixed mount respectively
Universal wheel, for the trailing wheel main shaft through chassis rear side, the trailing wheel main shaft both sides are respectively provided with a trailing wheel, the trailing wheel main shaft
There is whirlpool spring at middle part, and the whirlpool spring side is connected with wire reel, and the whirlpool spring outer ring is connected with chassis, the steel
Silk reel is fixed on trailing wheel main shaft by unilateral bearing, there is whirlpool spring outside the wire reel, the whirlpool spring it is interior
Circle is connected with wire reel, and respectively there is a brake disc whirlpool spring both sides, and the brake is arranged on corresponding brake disc,
The brake disc is connected with corresponding trailing wheel, there is damping spring on the extreme end of chassis, and the depression bar has a pair, and the pressure shaft passes through
There is a pair of guide rails two depression bar upper ends, the self-locking frame downside, and the pressure shaft both ends are stuck in corresponding guide rail, the dynamic cunning
Wheel shaft passes through two depression bar lower ends, has movable pulley in the middle part of the movable pulley axle, and respectively there is a neck roller movable pulley both sides,

Coordinate outside by steel leaf-spring with being connected on the outside of trailing wheel main wheel, the trailing wheel main wheel is sleeved on trailing wheel main shaft by rolling bearing
On, trailing wheel outer ring rubber is cased with the outside of the trailing wheel main wheel, buffering wheel is using caused by screw thread cooperation on axle and leaf spring cooperation
Circumferential buffer unit, when support board declines, wireline pulley mechanism drive hind axle rotate, now due to the frictional force on ground after
Wheel is failure to actuate, hind axle slow rotation under the leaf spring action of both sides, while hind axle drives nut close to during trailing wheel, piece
Spring produces axial deformation and torsional deflection, to moment of torsion caused by trailing wheel also constantly increase until overcoming frictional force and rotating.When
Wireline pulley mechanism kinematic finishes when no longer driving hind axle, hind axle in the presence of silk whirlpool spring and unilateral bearing is received no longer
Trailing wheel is driven, and is in relative static conditions.Now nut by by the reaction of screw thread and leaf spring away from trailing wheel, now trailing wheel
Unidirectionally can freely it rotate.Because buffering wheel can utilize the counter motion of two nuts in left and right to realize two wheels with friction speed
Motion, so buffering wheel can solve the problems, such as the differential turned to during freely dragging.
Further improvement of the present invention, there is mark on the cross bar of the baffle plate, the present invention can be as needed in the horizontal stroke of baffle plate
Corresponding mark is set on bar.
There are a pair of hasps further improvement of the present invention, the slip top panel upper end, can be easy to entirely by hasp
Slip top panel is closed in order to carry.
Further improvement of the present invention, the slip top panel upper center have a roller, in the slip top panel
Portion has one secretly to take turns, and sets roller and dark take turns can complementary goods entrance.
A kind of unloading power-assisted trailer of the invention, when the vehicle using motor lorry is unloaded, has the pull bar handle of automatic resilience function
Linked with rear wheel brake, so as to realize the safety arrestment during trailer unloading.The support board tiltable stretching of power-assisted trailer is simultaneously
Take and rise to boxcar altitude above deck.The slip baffle mechanism of design can play certain buffering during goods entrucking
Effect.Roller on support board（Dark wheel）Appear when stretching support board.So, worker can directly out of compartment goods along
Support board, which is taken advantage of a situation, to be pushed, to reduce the friction of goods and support board.When transporting goods, using guide-bar mechanism and wireline pulley mechanism
The advance kinetic energy that the gravitional force of goods itself is converted into trailer starts power-assisted effect so as to play.Damping bullet positioned at chassis
Spring can then provide good damping performance, and goods can be made more steady in transportation.In addition, we innovatively propose one
The rear-wheel structure of the flexible leaf spring combination left-right rotary motion thread of kind, trailer is both had and start buffering effect, and can is freely being dragged
Differential function is realized when dynamic, the unilateral bearing of hind axle installation ensure that the switching for starting power-assisted and freely dragging state.With it is same
Type unloading trailer is compared, and the application, which realizes, integrates power-assisted, convenient, economy, has good practicality and market
Promotion prospect, the carrying of middle-size and small-size goods among daily life can be widely used in, be applied to unload out of compartment by it（As soon
Pass goods）.
