Description
Technical field
The present invention relates to the technical field of fork truck more particularly to a kind of battery replacement devices of electri forklift.
Background technology
Fork truck is industrial transportation vehicle, refer to member pallet cargo is loaded and unloaded, stacking and short distance hauling operation
Various wheeled carrying vehicles.Fork truck can be generally divided into three categories usually using oil-burning machine or battery power, fork truck：Internal combustion is pitched
Vehicle, electri forklift and warehousing forklift.
Electri forklift refers to carrying out the fork truck of operation with electricity, and most of is all for battery-operated.Electri forklift be with
Accumulator is driving source, running motor and oil hydraulic system motor is driven, to realize traveling and handling operation.Accumulator is battery
In one kind, its effect is limited electric energy to be stored, and is used in suitable place.
Important component of the accumulator as electri forklift, for electri forklift in operation process, the electricity in accumulator can not
Breakdown consumes, it is therefore desirable to charge to accumulator, since the accumulator charging time is longer, to improve working efficiency, usually adopt
Ensure the continuous service of fork truck with the mode for replacing accumulator.Accumulator substitute mode common at present is usually by following several
Kind：
Mode one vertically slings used battery by suspender, which is removed from the right side of fork truck, and is put
On the specific purpose tools such as preprepared pallet, then suspender is transferred on reserve battery, and is lifted into vehicle frame；
Mode two, the structure that the Vehicle Frame Design of fork truck is opened at bottom opening and right side need to be by when replacing battery
Then reserve battery is moved into the vehicle frame of fork truck by another fork truck or specific purpose tool by used battery removal again；
Mode three, the structure that the Vehicle Frame Design of fork truck is opened at bottom belt idler wheel and right side, needs when replacing battery
Used battery is removed from vehicle frame by dedicated tool, then reserve battery is moved into the vehicle frame of fork truck again；
Accumulator is directly arranged at the tail portion of fork truck by mode four, will directly be made from rear portion by suspender when replacing battery
Used battery is hung out, then reserve battery is hung to the tail portion for transferring fork truck again.
It is above-mentioned existing to fork truck replace battery when, it usually needs the replacement of battery is completed by external tool,
Such as the auxiliary tools such as by hanging device, other fork truck are needed, larger working space is constantly needed replacing battery, when
It when working space deficiency, can bring greater inconvenience to operation, and the activity duration is long, operating type is complicated, replaces battery
Efficiency is low, in addition, battery is easy to happen inclination, falls in operation process, there are larger security risks.

When state, spacer pin 111 can be moved in the limiting slot 110 and be matched with limiting slot 110, therefore can pass through spacer pin
111 judge whether supporting leg 102 is deployed into vertical state with the matching relationship of limiting slot 110, as shown in figure 9, when supporting leg 102 not
It can be fully deployed to vertical state, spacer pin 111 can not be fallen into limiting slot 110, in 107 second end of corresponding fourth link
Collaborating bar 113 can not be lifted upwards, and then be blocked by block 206, cannot deviate from from second trigger ramp 205, to
It prevents trolley 100 from being detached from vehicle frame 200, and then ensures job safety, avoid the generation of safety accident.
When being pulled out battery from fork truck using the battery replacement device of fork truck in the present invention, as shown in figure 5, supporting leg 102
Under the effect of gravity, which can be expanded to vertical position, although the supporting leg 102 after expansion can be with the pallet 101 and company
Cam mechanism is formed between linkage, and the position of rear support leg 102 is unfolded with limitation and ensures the normal operation of the trolley 100,
But since the link mechanism includes first connecting rod 104 and second connecting rod 105, first connecting rod 104 and second connecting rod 105 are
Pivot joint relationship, when first connecting rod 104 and second connecting rod 105 are by under outer force effect, second connecting rod 105 is easily with respect to first connecting rod
104 are rotated, and to which supporting leg 102 can be caused to carry out accidentally folding, cause that trolley 100 is toppled over or battery is fallen, to can shadow
Ring the normal operation of trolley 100.First safety spacing mechanism is set in the present embodiment, is fully deployed when the supporting leg 102 is in
Stand up position when, which can match with the limiting slot 110 fixes the position of the supporting leg 102 to limit, to
It can ensure the normal operation of trolley 100, it is ensured that job safety.In addition, as shown in figure 9, passing through spacer pin 111 and limiting slot
110 matching relationship judges whether supporting leg 102 is deployed into vertical state, when occurring stone or other barriers on road surface,
Supporting leg 102 may not be able to be fully deployed to vertical state, and spacer pin 111 can not just be fallen into limiting slot 110, collaborate bar at this time
113 can be blocked by block 206, can not deviate from from second trigger ramp 205, operating personnel can carry out in road pavement
After cleaning, trolley 100 is pulled on, until the supporting leg 102 can be fully deployed to vertical position.
When being shifted battery on fork truck onto using the battery replacement device of fork truck in the present invention, as shown in figure 5, first by the dress
There is the trolley 100 of charged battery to be pushed at vehicle frame 200, when the bar 113 that collaborates on the trolley 100 is moved to the vehicle
On frame 200 at second trigger ramp 205 of trigger member 204, trolley 100 is continued to press on, the pushing of the second trigger ramp 205 collaborates bar
113, and then by the second end for collaborating bar 113 while pushing fourth link 107 on front and back two pairs of supporting legs 102, it is described
After the second end of fourth link 107 is pressed down, the first end of the fourth link 107 moves up certain distance, the fourth link 107
First end drives the third connecting rod 106 to move up, and the first end of traction grooved 1061 can drive the traction on the third connecting rod 106
Point 1051 is moved a certain distance along the traction grooved 1061, and then the towing point 1051 drives the second connecting rod 105 relatively described
First connecting rod 104 rotates clockwise certain angle, to drive the supporting leg 102 to be folded to the by the second connecting rod 105
One position；As shown in fig. 6, continuing to press on the trolley 100, the butting section 112 is resisted against the directive wheel 203 on vehicle frame 200
On, which is rotated to its rear, and the second connecting rod 105 continues clockwise to turn relative to the first connecting rod 104
It is dynamic, it is described to collaborate the continuation of bar 113 and slided along the bottom of the trigger member 204, Fig. 7 be fork truck battery replacement device in before
Supporting leg is moved to the structural schematic diagram on vehicle frame, as shown in fig. 7, continuing to press on trolley 100, front leg strut 102 can take in two branch
Seat 201 between space and be folded to the second position；Fig. 8 be fork truck battery replacement device in small Chinese herbaceous peony rear support leg move completely
Structural schematic diagram on to vehicle frame, as shown in figure 8, continuing to press on trolley 100, rear support leg 102 continues to fold, and then rear support leg
102 can take in the space between two bearings 201 and be folded to the second position.
On the basis of the above embodiments, it is preferable that as shown in Figure 1, the bottom of the pallet 101 is equipped with front and back two pairs of supporting legs
102, the castor on the front leg strut 102 is directional wheel, and the castor on the rear support leg 102 is the universal wheel that can carry out self-locking.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
