Description
Technical field
The present invention relates to a kind of big stroke hydraulics to go up and down rack device.
Background technique
Currently, the liftable hydraulic device of well known engineering truck, typically only hydraulic module vehicle is gone up and down, total to go up and down
Stroke 700mm or so, lifting stroke is relatively low, in this case, such as high when freight needs to place higher position
Bridge, it is just relatively difficult.
Solve this problem at present is typically all to be solved by both schemes: a kind of scheme is cargo transport to mesh
Ground, need a dedicated lifting means, cargo raised up from vehicle, and promoted arrive certain height, then goods
It is placed on final desired position, this scheme is the disadvantage is that need a dedicated lifting means at the scene.Another scheme is
In cargo entrucking, just the elevated height after cargo entrucking to transport destination needed for height, typically vehicle with
Place a bracket, so that cargo be made to reach required height, this scheme between cargo the disadvantage is that vehicle in motion, cargo
Center of gravity it is high, when walking, is very unstable, even if speed falls below very low, and there are certain risks, on traveling road
Barrier in journey because of height-limiting frame etc must go troubleshooting.In addition, when carrying, promoting the cargo at ton weight, single promotion
Equipment support force is insufficient, and there are security risks.
Summary of the invention
The object of the present invention is to provide a kind of big stroke hydraulics to go up and down rack device, is suitable for carrying tons of big parts, such as bridge
Beam module, bridge pier etc..
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
A kind of big stroke hydraulic lifting rack device, including at least one lifting unit, the lifting unit include modular cart, set
Set the frame assembly in the modular cart, the frame assembly include the first elevating mechanism, the second elevating mechanism and on
Frame, first elevating mechanism are provided with multiple, and multiple first elevating mechanisms are respectively supported at the upper ledge
The surrounding of frame bottom surface, second elevating mechanism are provided at least one, and second elevating mechanism is supported on described
The middle part of upper frame bottom surface, the top surface of the upper frame are placed side.
Preferably, the frame assembly further includes lower frame, and the lower frame is arranged in the modular cart, institute
The first elevating mechanism, the second elevating mechanism stated are arranged on the lower frame.
Preferably, first elevating mechanism is telescopic cylinder.
Preferably, second elevating mechanism is scissors type elevating frame.
Preferably, the upper frame is square, and there are four the first elevating mechanism settings, first described in four
Elevating mechanism is respectively supported on four angles of rectangular upper frame bottom surface, and there are two the second elevating mechanism settings.
Preferably, the modular cart include platform, the suspension mechanism for being connected to the platform base, be connected to it is described
Suspension mechanism on running mechanism and power plant module, the frame assembly is arranged on the platform.
It is further preferred that the suspension mechanism is Liftable hanging mechanism.
Preferably, the height of the lifting unit is 2200-7200mm.
Preferably, when the lifting unit is provided with multiple, multiple lifting units are along the device
Width direction and/or length direction distribution.
It is further preferred that the device further includes the control machine of the multiple lifting unit synchronous operations of control
Structure.
Due to the above technical solutions, the present invention has the following advantages over the prior art:
The present invention, which can make lifting unit in the height direction, has the variation of larger stroke, support force enough, can be according to cargo size
Height is different, to adjust the height of crane, so as to carry the cargo of high-altitude placement, such as bridge, has lifting force
Greatly, the features such as lifting travel is big, stability is good, and structure and control system are simple, and failure rate is low, and easy to maintenance, structure is closed
Reason, manufacturing cost is low, thus greatly reduces total transportation cost.

Specific embodiment
The present invention is described with reference to the accompanying drawings and embodiments:
A kind of big stroke hydraulic as shown in Figure 1 goes up and down rack device, including at least one lifting unit 1, and lifting unit 1 includes mould
Block vehicle, the frame assembly that modular cart is set.Wherein:
Modular cart includes platform 20, the suspension mechanism 21 for being connected to 20 bottom surface of platform, the traveling machine being connected on suspension mechanism 21
Structure 22 and power plant module 23, frame assembly are arranged on platform 20.In the present embodiment: suspension mechanism 21 is outstanding using liftable
Suspension mechanism, the lifting travel of lifting hanging mechanism is in 700mm or so.
Frame assembly includes lower frame 30, upper frame 31, the first elevating mechanism and the second elevating mechanism.Lower frame 30 is set
It sets on the platform 20 of modular cart, the first elevating mechanism, the second elevating mechanism are arranged on lower frame 30, and are supported on frame
On 31 bottom surface, the top surface of upper frame 31 is placed side.
First elevating mechanism is provided with multiple, and multiple first elevating mechanisms are respectively supported at the surrounding of 31 bottom surface of frame,
Second elevating mechanism is provided at least one, and the second elevating mechanism is supported on the middle part of 31 bottom surface of frame.In the present embodiment:
Lower frame 30, upper frame 31 are square, and there are four the settings of the first elevating mechanism, four the first elevating mechanism sides of being respectively supported at
In shape on four angles of 31 bottom surface of frame, there are two the settings of the second elevating mechanism, and two the second elevating mechanisms are supported on rectangular
The middle part of 31 bottom surface of frame.First elevating mechanism uses telescopic cylinder 32, and the second elevating mechanism uses scissors type elevating frame
33, it can pass through hydraulic-driven.
In this way, modular cart and frame assembly all have elevating function, the lifting travel of entire lifting unit is 2200-
7200mm。
When lifting unit 1 is provided with multiple, width direction and/or length direction point of multiple lifting units 1 along device
Cloth, such as figure be width direction two, length direction two.Device, which is also equipped with, controls the control that multiple lifting units 1 are run simultaneously
Mechanism processed.It can be connected with each other, can not also be connected with each other between multiple lifting units 1, but to keep the synchronization of movement
Property.
In loading, it is not required to the certain height of freight lifting to be placed on device, lifting unit 1, which can first drop, to be set
2200mm, device in the process of moving, do not go troubleshooting due to the barrier of height-limiting frame etc in distance, also not because of center of gravity of goods mistake
Height goes to reduce the speed travelled, drives to destination, is not required to a spare elevator also to promote the height that cargo reaches certain,
Modular cart and frame assembly rise, and are such as increased to 7200mm, so that cargo is given rise to height required when cargo is placed.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
