Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of existing handbarrow tankette car is improved, and can save manpower, the handbarrow car of band mechanical lifting gear easy to use.
The purpose of this utility model is finished by following technical solution, which comprises at least framework, at least two wheels in front and back and load-bearing panel etc., the below is provided with a screw mandrel that has finishing bevel gear cuter second in the middle of the described load-bearing panel, this screw mandrel links to each other with an overcoat moving up and down by the nut that is threaded, the bottom of this overcoat is connected with mini-roundabout by a screw, and finishing bevel gear cuter second is then joined by a finishing bevel gear cuter first and a rotary handle device.
Described rotary handle device comprises a straight-tooth gear that links to each other with finishing bevel gear cuter first turning cylinder, and this straight-tooth gear links to each other with pull bar by a rack shaft.
Described rack shaft cooperates by tooth bar and straight-tooth gear and links to each other, and the arc shape position of described rack shaft is provided with and is used to the steel ball registration device that commutates and locate.
Described spur rack is connected with key with the finishing bevel gear cuter first, and finishing bevel gear cuter second also is connected with key with screw mandrel, and screw mandrel is provided with locating bush and connects with screw.
Screw mandrel described in the utility model is outer to be provided with feather key by nut bonded assembly overcoat, and this feather key is provided with the limiting stopper of restriction stroke.
Be connected with a traffic cycle with screw on the load-bearing panel of described screw mandrel top, and between traffic cycle and load-bearing panel, be provided with the rolling ring recess that ball is installed.
Characteristics such as the utility model belongs to a kind of improvement to prior art, and it has simple in structure, and is easy to use, applied widely, can save manpower, and is safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plane arrangement structure scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1,2, the utility model includes framework 1 at least, at least two wheels in front and back 2 and load-bearing panel 3 etc.The below is provided with a screw mandrel 5 that has finishing bevel gear cuter second 4 in the middle of the described load-bearing panel 3, this screw mandrel 5 links to each other with an overcoat 7 moving up and down by the nut 6 that is threaded, the bottom of this overcoat 7 is connected with mini-roundabout 9 by a screw 8, and finishing bevel gear cuter second 4 is then joined by a finishing bevel gear cuter first 10 and a rotary handle device.
Rotary handle device shown in the figure comprises a straight-tooth gear 11 that links to each other with finishing bevel gear cuter first 10 turning cylinders, and this straight-tooth gear 11 links to each other with pull bar 13 by a rack shaft 12.
Described rack shaft 12 cooperates by tooth bar and straight-tooth gear 11 and links to each other, and the arc shape position of described rack shaft 12 is provided with and is used to the steel ball registration device that commutates and locate.
Straight-tooth gear 11 described in the utility model is connected with finishing bevel gear cuter first 10 usefulness keys, and finishing bevel gear cuter second 4 also is connected with key with screw mandrel 5, and screw mandrel 5 is provided with locating bush 14 and connects with screw 15.
Be provided with feather key 16 by nut 6 bonded assembly overcoats 7 outside the screw mandrel 5 described in the utility model, and this feather key 16 is provided with the limiting stopper 17 of restriction stroke.
Be connected with a traffic cycle 18 with screw on the load-bearing panel 3 of screw mandrel described in the utility model 5 tops, and between traffic cycle 18 and load-bearing panel 3, be provided with the rolling ring recess 20 that ball 19 is installed.
The utility model is that a cover mechanical lifting gear is installed on the tankette car, under the situation that does not have other machinery to assist, relies on tankette car self just can carry and lifting weight.During use, when pull bar was in ground and is level or certain angle position, pull bar can be done traction and use; When pull bar is in when being the position of 90 degree with ground, rotating tension bar, pull bar drive rack shaft, and rack shaft drives straight-tooth gear, the finishing bevel gear cuter first is rotated, and the finishing bevel gear cuter first drives finishing bevel gear cuter second again, and finishing bevel gear cuter second drives screw mandrel, screw mandrel drives nut, and mini-roundabout and overcoat are stretched out or indentation.Break away from ground when mini-roundabout and overcoat are retracted into, the wheel kiss the earth of tankette car is done carrying work; When mini-roundabout and overcoat reach kiss the earth, the tankette wheel breaks away from ground, can the lifting weight.During veer, stretch out mini-roundabout and overcoat, the mini-roundabout kiss the earth just can be placed on pull bar with ground level or is in the position veer of certain angle.When turning to, the friction of rolling that relies on traffic cycle to do during the friction of tankette car and weight, and the friction of rolling that relies on mini-roundabout to do when tankette car and ground-surface friction.So turn to very flexible and laborsaving.The utility model has been realized handbarrow tankette car carrying heavy goods and the two-in-one function of lifting weight, uses more conveniently, and turning to of tankette car is more flexible laborsaving.
