Description
Technical field
The present invention relates to machinery equipment field, and in particular to a kind of pit-hole supporting protection device of aerial work platform.
Background technology
Aerial work platform (Aerial work platform) be serve industry-by-industry work high above the ground, equipment install,
The product of the mobility work high above the ground such as maintenance.Aerial work platform is broadly divided into scissor-type according to the difference of itself mechanism
Aerial work platform, trailer-type aerial work platform, crank type aerial working platform, straight arm type aerial work platform, aluminium alloy
Aerial work platform, double-cylinder type aerial work platform, the major class of spider-type aerial work platform seven.
For aerial work platform, more particularly to the security of this body structure consideration.The knot of aerial work platform
Structure, substantially comprising walking structure, lifting structure and platform structure.Wherein, the effect of walking structure is contacted with ground, and on ground
Movement is travelled on face, platform structure is stood for operator, lifting structure is used to connect walking structure and platform structure, and
In the vertical direction is lifted.
When workman stands the operation on platform structure, when and need walking structure to move, and aerial work platform
In order to avoid colliding in the process of walking with the barrier on ground, such as stone or mound, often have one with ground
Fixed distance, this distance is conducive to the movement of aerial work platform smooth.But meanwhile, this distance also has certain safety hidden
Suffer from, either when vehicle movement or vehicle are parked in operation place, ground is likely to the presence of hollow or pit-hole, makes
Walking structure is placed on ground and unstable, and workman stands on high-level platform structure and just has the danger toppled.
The content of the invention
It is an object of the invention to provide a kind of pit-hole supporting protection device of aerial work platform, in mobile status, there is provided
Larger ground clearance ensures to move smooth, in work high above the ground, there is provided ground supports, improves security.
Above-mentioned technical purpose of the invention technical scheme is that：A kind of hole of aerial work platform
Hole supporting protection device, comprising running gear, operating platform and connect the running gear and the operating platform and can so that
The lifting structure of the operating platform in the vertical direction lifting, also comprising base and protection device, the protection device is included
The backplate being hinged with the base, the backplate overturns when the operating platform has been lifted.
Used as of the invention preferred, when the operating platform rises, the backplate extends in vertical direction, as the behaviour
When being fallen as platform, the backplate inwardly overturns, and extends in the horizontal direction.
As it is of the invention preferably, the protection device also comprising the piece under pressure that is connected with the lifting structure and with it is described
The driving member of backplate connection, the driving member is used to be contradicted with the piece under pressure, is overturn in the presence of the piece under pressure described
Backplate.
The running gear is stood on ground, and can be moved on the ground.The underframe is provided with lifting structure, the liter
Drop structure can be hydraulic stem, can be scissors structure, can be telescopic platform, and effect is to drive operating platform in the vertical direction
Lifting.Workman stands on the operating platform when operation.The innovative point of the technical program, is the protection dress
The design put, is hinged with the backplate on underframe, and the backplate possesses certain weight, possesses at least two states, i.e., certainly
Right state and rollover states.Nature refers in the presence of external force is not received, to be influenceed by gravity, under the backplate nature
Hang down, extend in vertical direction.Now the lower edge of backplate is close apart from ground, works as ground relief, when there is pit-hole, institute
State backplate just to be contradicted with ground, increase the stability of whole aerial work platform, so, nature also corresponds to work high above the ground and puts down
The job state of platform.And in rollover states, the lifting structure drives the operating platform to decline, when declining, it is described under
Casting die is pushed, and drives the driving member running, and the backplate that will extend vertically originally is opened.The backplate is with the underframe
It is hinged, is overturn when being contradicted by the driving member, the backplate is inclined or horizontal-extending after upset, now with ground
The distance in face is just big.Rollover states are corresponding be exactly aerial work platform mobile status, now aerial work platform rely on
The running gear is movably walking on the ground, the larger ground clearance of the backplate ensure the backplate not with ground on soil
The barriers such as heap, stone are interfered or collided.
As it is of the invention preferably, the piece under pressure include be connected with the lifting structure push rod, be located at the push rod
End and the spring being connected for the boss contradicted with the driving member and with the push rod.
The piece under pressure is connected with the lifting structure, and the push rod is connected on the lifting structure, when the lifting
When structure declines, the boss of the push rod end is just contradicted with the driving member, drives the driving member running.
As it is of the invention preferably, the lifting structure is provided with fixed mount, and the push rod is connected on the fixed mount,
The spring one end is contradicted on the fixed mount, and the other end is contradicted on the boss.
As it is of the invention preferably, the driving member include rocking arm, the one end be used for supported with the piece under pressure
Touch, the other end is connected with lifting connecting plate, the lifting connecting plate end is hinged with contiguous block, and the contiguous block connects with the backplate
Connect.
Articulated section preferably is provided with the middle part of the rocking arm as of the invention, the articulated section is connected with the underframe.
As it is of the invention preferably, the backplate exist two sets, be symmetrically arranged at the underframe both sides.
As it is of the invention preferably, one end that the rocking arm is contradicted with the piece under pressure is provided with Non-slip material.
As it is of the invention preferably, the lifting connecting plate bottom offers waist type groove, and the rocking arm connects the waist type groove.
When the boss is pushed, be pressed on one end of the rocking arm, this position in order to preferably it is anti-skidding with connect
Touch, it is wear-resisting to be provided with Non-slip material, anti-skidding.The rocking arm is connected by articulated section with the underframe, lever is formed, when being provided with
When the one end for stating Non-slip material declines, the other end then rises.One end of rising is to be connected to the lifting connecting plate bottom to open up
Waist type groove in, drive the whole lifting connecting plate to rise.When the lifting connecting plate rises, the contiguous block, institute are driven
State contiguous block and be connected with the backplate, the backplate is packed up to turning inside out by the contiguous block.
Preferably the lifting structure includes multiple lifting arms as of the invention, and multiple lifting arms are interconnected to
Scissors structure.
As it is of the invention preferably, the piece under pressure is connected on fixed mount, and the fixed mount is connected to of most bottom
On the lifting arm.
In sum, the present invention has the advantages that：
1st, in nature, backplate is naturally drooped by gravity, and lower end is near with ground distance, supports whole work high above the ground to put down
Platform, stability of strutting system when lifting ground is uneven, increases safety.
2nd, it is that backplate possesses larger terrain clearance to turning inside out in rollover states, is difficult to be sent out with the soil block on ground
Raw interference and collision.
3rd, the switching of nature and rollover states, is automatically performed, it is not necessary to extra by the lifting of lifting structure
Set, efficiency high does not have error.
4th, when operating platform is located at high position, backplate shields in the raw, and operating platform is located at lower position
When, backplate plays anticollision in rollover states.
