Abstract
The utility model relates to an electric lift handbarrow for carrying object, in particular to a guide screw lift system of the electric lift handbarrow, wherein two parallel guide rails are fixedly connected with each other to form the car body of the handbarrow by a connection board, a luggage carrier is arranged on the front side of the lower end of the two guide rails between which a guide screw is uprightly arranged, wherein one end of the guide screw is drivingly connected with the output end of a generator, a threaded sleeve engaged with the thread of the guide screw is fixedly arranged in the middle of the back side of the luggage carrier, guide wheels engaged with the two guide rails on both sides of the car body are respectively arranged on both sides thereof. The utility model has the advantages of simple structure, low manufacturing cost and reliable performance, and resolves the problems of complex structure, high manufacturing cost, easy invalid hydraulic system and unreliable performance or the like existed in present hydraulic lift handbarrow.
Description
Technical field
The utility model relates to a kind of electric up-down hand barrow of carrying object, particularly a kind of electric up-down hand barrow screw mandrel jacking system.
Technical background
The hand barrow of band elevating function can be widely used in factory, the station, harbour, the airport, the warehouse, hospital and multiple occasion with smooth place need carrying small-sized weight, as a kind of tubular guide rail hydraulic lift truck (patent No.: CN94215782.6), comprise car body, plunger fuel pump, hydraulic ram, cargo carrying support and guide rail, described lift car also comprises gear type sprocket wheel and chain, the gear type sprocket wheel is positioned at the piston rod upper end on hydraulic ram top, chain one end on the sprocket wheel links to each other with the upright crossbeam of car body, the other end links to each other with the cargo carrying support, described guide rail is made by steel pipe, the guide rail lower end is connected with car body, middle-end partly is fixed in the car body stand, the upper end is semicircular arc, the straight line portion of whole guide rail is set in the cargo carrying support top shoe, constitute bearing fit, the straight line portion guide rail is by the clamping of cargo carrying support bottom roller, and constituting rolls cooperates.The hydraulic efficiency elevation structure structure that above-mentioned patent scheme adopts is comparatively complicated, and manufacturing cost is higher, and hydraulic efficiency pressure system lost efficacy easily, and performance is unreliable.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, and manufacturing cost is lower, the electric up-down hand barrow screw mandrel jacking system of dependable performance, the structure that has solved existing hydraulic lifting hand barrow existence is comparatively complicated, manufacturing cost is higher, and hydraulic efficiency pressure system lost efficacy easily, problem such as performance is unreliable.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: two guide rails that be arranged in parallel are fixedly connected into the hand barrow car body by connecting panel, front side, lower end at two guide rails is provided with the cargo carrying frame, between two guide rails, be provided with the screw mandrel of vertical setting, the mouth of described screw mandrel one end and motor is in transmission connection, described cargo carrying frame rear side middle part is installed with the screw collar that cooperates with wire rod thread, and described cargo carrying frame both sides are respectively equipped with the guide wheel that the guide rail with the car body both sides cooperatively interacts.Screw mandrel is rotated by motor-driven, the screw collar that is fixed on the cargo carrying frame cooperates with wire rod thread, because screw axis is to being limited, Gu the screw collar of screw thread fit can move up and down under the situation that screw mandrel rotates with it, thereby drive the lifting of cargo carrying frame, can be when goods is shelved on the cargo carrying frame owing to the driving lifting of motor, to reduce bearer's labour intensity, because what adopt is the physical construction of wire rod thread cover, its structure is comparatively simple, manufacturing cost is also lower, and performance is also comparatively reliable.
As preferably, be rotatably connected on the connecting panel by bearing on the described screw mandrel, its lower end is connected with the mouth of motor.
As preferably, described cargo carrying frame rear portion is respectively equipped with top tumbler axle and lower guide wheel shaft near both sides, and the cross section of described guide rail is back-shaped structure, and the guide rail medial surface is provided with the opening that is provided with vertically; Top tumbler axle and lower guide wheel shaft one end extend in the back-shaped structure of guide rail, and are respectively equipped with top tumbler and lower tumbler at top tumbler axle and lower guide wheel shaft end, and top tumbler and lower tumbler are limited in the back-shaped structure of guide rail.The guide wheel that is provided with in the both sides of cargo carrying frame is limited in the back-shaped structure of guide rail; can play directional tagging to the oscilaltion of cargo carrying frame; swinging of the cargo carrying frame of avoiding, the cooperation of protection wire rod thread cover is not damaged, and prolongs service life of the present utility model.
Therefore, the utlity model has simple in structurely, manufacturing cost is lower, characteristics such as dependable performance.
