Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of climbing stairs drag lorry, include main car frame 2, and the front end of main car frame 2 is provided with handle mechanism 1, main car frame 2 Both sides installation limited location fence 3, the bottom of main car frame 2 is provided with four triangle wheel mechanisms 4, and 1 set of the handle mechanism inserts in main car In the hollow square tube of the front end of frame 2, and can wherein telescopic slide to adjust the different extension elongation of handle mechanism 1, hollow square tube Upper side offers screwed hole, and fixing screws are equiped with the screwed hole, can make handle by tightening the fixing screws Mechanism 1 is fixed in the hollow square tube of the front end of main car frame 2.

Spacing fence 3 is made up of a cross bar and some L-shaped vertical rods, and the horizontal set in L-shaped vertical rod lower end inserts in 2 liang of main car frame In the square hole of side and telescopic slide, the square hole upper side screwed hole can be offered wherein, be equiped with the screwed hole solid Determine screw, relative position of the spacing fence 3 in main car frame 2 can be fixed by tightening the fixing screws.

Mechanism of triangle wheel mechanism 4 includes the oil-pressure caliper 41 and main shaft 43 being installed on main car frame, on main shaft 43 It is set with brake disc 42 and two set squares 46 successively from inside to outside, brake disc 42 and the phase of set square 46 of inner side are fixed, Three triangular arrangeds are clamped between two set squares 46 divides rotating shaft 47, each divides in rotating shaft 47 and is equiped with ratchet 45, be set with crystal wheel 44 outside ratchet 45, ratchet 45 make crystal wheel 44 can only along originally drag lorry direction of advance to rotate and can not be anti- To rotation, the jaw of oil-pressure caliper 41 is located at the circumference outer ring of brake disc 42, when oil-pressure caliper 41 controls oil circuit oil-feed, oil pressure Clamp 41 can be stuck by brake disc 42, so that set square 46 can not rotate.

Handle mechanism 1 includes the Qian shape that set is inserted on main car frame 2 and fixes handle 12, and the middle part that Qian shape fixes handle 12 is horizontal Movable handle 11 is installed at bar, movable handle 11 and fixed handle 12 are be hinged, and piston rod 13 is hinged with movable handle 11, Gu Surely it is hinged with cylinder body 15 on handle 12, piston rod 13 is set with cylinder body 15 and is integrated, and piston rod 13 can stretch cunning in cylinder body 15 Move, and the internal cavities of cylinder body 15 are divided into oil-filled chamber 16 and without oil pocket 17 by piston rod 13, and oil-filled chamber 16 is interior to be full of hydraulic oil And communicated with the control oil circuit of oil-pressure caliper 41, no oil pocket 17 is communicated with ambient atmosphere, and spring 14, bullet are set with outside piston rod 13 The both ends of spring 14 are connected to the inwall of movable handle 11 and the left side of cylinder body 15 respectively.

The spacing outside of fence 3 is equiped with Universal caster 5, can effectively avoid dragging lorry to contact with the hard of peripheral obstacle, make Its movement is more smooth.

Originally lorry periphery is dragged to be additionally provided with quick bundling belt, in order to the quick bundled fixed to goods.

Specifically used method：

This drags lorry both to can be used for hauling the haul that can be used at stairway step at level land.Both four three can be made Horn ring 4 land it is horizontal use, two three horn rings 4 of rear end is landed vertical use.

In use, first according to the cargo size of required haul, stretching position of the adjustment spacing fence 3 in both sides in main car frame 2 Put, and extended position of the handle mechanism 1 in main car frame 2, then tighten the fixing screws of corresponding opening position.

When in level land dragging, in use, three horn rings 4 are without rotating, only needing the crystal wheel 44 on three horn rings 4 to rotate can be real Now this movement for dragging lorry.This drags lorry to advance or turn to, but in the presence of ratchet 45, can not retreat, and this function can During ensureing to drag lorry to be in slope position, setback will not occur.

When at stairway step haul when, will not be blocked because of stair it is motionless, when crystal wheel 44 is stuck, three Gusset 46 begins to rotate, and so as to overcome the problem of being stuck, forms oblique line and uniformly lifts, you can realize that this drags lorry in building Movement at halfpace rank.

Operator need to hold handle mechanism 1 in dragging process, when handle mechanism 1 is deviate from from hand accidentally, movable handle 11 It is turned out under the elastic force of spring 14, piston rod 13 becomes relative to 15 protruding motion of cylinder body, the now volume of oil-filled chamber 16 Small, hydraulic oil is flowed at the oil-pressure caliper 41 of triangle wheel mechanism 4 along control oil circuit, the meeting in the presence of hydraulic oil of oil-pressure caliper 41 Brake disc 42 is locked, so as to fixed triangle plate 46, it is stopped operating, simultaneously because the one-directional rotation effect of ratchet 45, Crystal wheel 44 can not be retreated rotation, effectively prevent after dragging lorry to slip out of the hand accidentally, retreat the problem of falling stair, this is dragged goods Car is safer when using.

Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people Member can carry out various changes and amendments in the range of without departing from this item utility model technological thought completely.This item is real The content being not limited to new technical scope on specification, it is necessary to which its technology is determined according to right Property scope.
