Description
Technical field
The present invention relates to logistics fields, more specifically, it is related to a kind of Pallet Truck for capableing of smooth up/down steps.
Background technique
Preferred means of transport when Pallet Truck is larger short-distance transport or more object, structure is relatively simple, uses
Also more convenient therefore very wide in logistics field utilization.
Existing Pallet Truck when in use, if in movement routine occur increase or reduce suddenly this kind of similar suddenly
The region of step, if passing through Pallet Truck by force, will lead to Pallet Truck then Pallet Truck would become hard to smoothly directly pass through
Generate it is biggish jolt, so that the movement routine of Pallet Truck is become smooth even by plate is set up, in Pallet Truck moving process
Also inclination can be generated, the object on Pallet Truck is also easy to fall or change original position.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of planker for capableing of smooth up/down steps
Vehicle enables car body to smoothly pass over class by the wheel for being hinged on the mobile jib of car body two sides and being hinged on mobile jib
Like step-like terrain, and the holding of car body top surface can be made horizontal.
To achieve the above object, the present invention provides the following technical scheme that one kind is capable of the Pallet Truck of smooth up/down steps,
Including car body, no less than three horizontally disposed mobile jibs of pivot center, mobile jib are hinged on two opposite side walls of car body
It is parallel to this one side wall, the midpoint and car body of mobile jib are hinged and are fixedly connected with the horizontally disposed main motor of output shaft, main electricity
Machine is fixedly arranged on car body；The both ends of mobile jib are hinged with the wheel that pivot center is parallel to mobile jib pivot center, fixed on wheel
There is an auxiliary-motor, the output shaft of auxiliary-motor and being fixedly connected for wheel coaxial line, auxiliary-motor is fixedly arranged on mobile jib；Mobile jib is vertically arranged
When, the bottom end of mobile jib is located at the subjacent of car body, when mobile jib is horizontally disposed with, the articulated shaft of wheel be located at two end faces of car body it
Outer region.
By using above-mentioned technical proposal, when in use, if mobile jib is in a vertical state, when encountering step, can make
All mobile jibs rotate clockwise certain angle, make car body far from step, then proceed to rotate clockwise the mobile jib near step,
So that a wheel on mobile jib is located at the top face of step and is located at this wheel between the articulated shaft and step of mobile jib,
A wheel on the mobile jib of step is set to abut plate on the top surface of step then as the mobile jib that rotates of car body,
Thus become all wheel support car bodies again, continues thereafter with the method using this rotation mobile jib, and can be according to car body
On object private room situation judge body gravity position, rotation mobile jib come make car body obtain stablize support by way of make car body
It is promoted on higher leveled step, and car body is able to maintain level always in this process.In this process, car body can
The height for the step climbed up can be different and different with the articulated position of mobile jib on the car body, user can according to demand itself
Adjustment.
Preferable: the mobile jib has eight, and eight mobile jibs are evenly and symmetrically distributed in the opposite two side walls of car body.
By using above-mentioned technical proposal, enable to the two sides of the theoretic position of centre of gravity of car body all there are four mobile jib,
It enables to the movement of car body more stable, while excessively cost will not be caused to get higher because of mobile jib again.
Preferable: the side wall top that the car body is connected with mobile jib is installed with horizontally disposed baffle, baffle vertically to
Under direction on wheel is covered, when mobile jib is vertically arranged, wheel is located at the lower section of baffle.
By using above-mentioned technical proposal, can reduce mobile jib and wheel rotation makes to influence car body normal use or the external world
Sundries influences the possibility of mobile jib and wheel rotation.
Preferable: there are four L-shape snap-gauges for sliding connection in the horizontal direction on the top surface of car body, and four snap-gauges are in rectangle
The distribution of four tip-angled shapes, and the moving direction of two neighboring snap-gauge is orthogonal, is installed on snap-gauge snap-gauge being fixed on vehicle
Fixation kit on body top surface.
By using above-mentioned technical proposal, remember that four snap-gauge is fixed on the car body by fixation kit, it can be by object
The stable placement of body on the car body, reduces the possibility that object is fallen from car body.
It is preferable: to be opened up on the top surface of car body there are four the sliding slot that section is in convex character shape, four sliding slots radially distribute
And one end of four sliding slots is located at the middle position of car body, fixation kit includes the fixed block being fixedly arranged on snap-gauge side wall, spiral shell
Line is connected to length direction and sliding slot sliding company on fixed block and along the vertical direction through the bolt of fixed block and along the chute
The type block connect, bolt are vertically arranged and are threadedly coupled with type block.
By using above-mentioned technical proposal, when tightening bolt, bolt will drive type block towards clamp moving, thus
So that the frictional force between frictional force and snap-gauge between type block and sliding slot inner wall and car body top surface increases, this can be incited somebody to action
Snap-gauge is stably fixed to a certain position in car body top surface, easy to operate.
Preferable: vehicle body is hollow, and the end that the sliding slot is located at car body top edge is offered along vertical side
To the lifting groove for running through car body top surface, the vehicle body below lifting groove is installed with the cylinder being vertically arranged, the piston rod of cylinder
To utmostly and when snap-gauge and type block are located in lifting groove, the piston rod of cylinder is connected to the bottom surface of type block for elongation upwards
On, the piston rod retracted downward of cylinder to utmostly when, it is most short straight between the top surface and car body top surface of the piston rod of cylinder
Linear distance is equal to snap-gauge top surface to the shortest straight line distance between the bottom surface of type block.
By using above-mentioned technical proposal, when not needing using snap-gauge, snap-gauge can be slid at lifting groove, and control
The piston rod of cylinder processed is shunk, and the bottom surface of type block can be connected in the piston rod top end of cylinder and decline together at this time, and in gas
When the piston rod of cylinder is contracted to utmostly, the top surface of snap-gauge can reduce snap-gauge and use car body with the either flush of car body
Influence.
Preferable: fixed there are two horizontally disposed hydraulic cylinder on the car body top surface, two hydraulic cylinders are located at vehicle
It at the both ends of body and is oppositely arranged, the piston rod end of hydraulic cylinder is installed with clump weight, length direction of the clump weight along hydraulic cylinder
Sliding is connected on car body top surface.
By using above-mentioned technical proposal, the position of clump weight can be adjusted by hydraulic cylinder, so that car body is passing through class
Like step landform when it is more stable.
In conclusion the present invention is had the advantages that compared with the prior art 1. by being hinged on car body two sides
Mobile jib and the wheel being hinged on mobile jib enable car body to smoothly pass over similar step-like terrain, and can make
Car body top surface keeps horizontal.
