Description
Technical field
The utility model relates to the dumpers that a kind of band is grabbed with vehicle, more particularly to one kind is with vehicle gripping apparatus.
Background technique
The entrucking of cargo and to unload all be or to pass through external grasping operation mechanism by manpower transport on traditional transport vehicle
It realizes.Manual handling will use a large amount of manpower, and efficiency is lower, and there are security risks；The grasping operation of external grasping operation mechanism, cargo
An external grasping operation mechanism is needed in entrucking, cargo is unloading and needing an external grasping operation mechanism, especially for field
Institute, grasping operation mechanism are extremely difficult to destination, and the grasping operation of external grasping operation mechanism is only applicable to fixed point grasping operation, and environmental suitability is poor.Specially
Benefit number discloses a kind of postposition with the transport vehicle of vehicle grapple structure for 201620796719.5 Chinese patent, is able to solve above-mentioned
Problem.
However pass through practice discovery, there is also following shortcomings with the transport vehicle of vehicle grapple structure for a kind of above-mentioned postposition:
1, due to being set to the back segment of transport vehicle with vehicle grapple structure, so that the transport vehicle of this kind of topology layout does not have
Self-unloading function, it can be considered to be set to the middle section of transport vehicle with vehicle grapple structure, the compartment at its so rear can be real
Existing self-unloading function, referring to figures 1-4, however, tradition is straight-arm with the arm of vehicle grapple structure, since size is larger, in inoperative
Biggish space is still occupied under state, therefore is to be located at compartment just in vehicle travel process with the arm of vehicle grapple structure
Top, it when vehicle, which arrives at the destination, needs self-unloading, needs first to lift the arm with vehicle grapple structure, otherwise with vehicle grapple structure
The arm of arm will affect the self-unloading function in compartment, and needing again after the completion of self-unloading function again will be with the drop of the arm of vehicle grapple structure
Under, therefore vehicle self-unloading process is relatively complicated, therefore consider to develop it is a kind of towards sideways folding arm form with vehicle grapple structure.
2, due to traditional band with the transport vehicle of vehicle grapple structure when grabbing material, with two below grapple structure supports
Leg is used to support car body, when gripping in the material at left and right sides of crawl compartment with vehicle, if material is overweight to may result in vehicle
Rollover, in the case that traditional vehicle is straight-arm if it is the arm with vehicle grapple structure, using hoist engine is flexible and landing, volume
Raise and rangefinder be installed on the steel cable of machine, but folding arm form with hoist engine can not be installed on vehicle grapple structure, therefore just can not yet
Rangefinder is installed, therefore cannot achieve anti-rollover function；
3, for traditional arm with vehicle grapple structure only with automatic anti-drop device, this is the device using inertia lock,
It uses in general situation with oil cylinder interlock fit, but under emergency case, such as takes a sudden turn, rollover can be by when shock
It is opened voluntarily to impact, and causes secondary injury；
4, traditional gripping apparatus with vehicle grapple structure only has two valves, pintongs, five valves, six valves, grab square-folded object and
When cambered surface object, the grip of traditional gripping apparatus with vehicle grapple structure is also difficult to meet the requirements.
Summary of the invention
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide one kind with vehicle gripping apparatus, can be assembled with it band with
The dumper that vehicle is grabbed.
Purpose of the utility model is realized as follows:
One kind is with vehicle gripping apparatus, it is characterised in that gripping apparatus includes circular gripping apparatus seat, the upper end of the gripping apparatus seat and rotation
The lower end of device connects, and multi-disc has uniformly been hinged out in the outer circle of the gripping apparatus seat and has grabbed valve, every grab valve be internally provided with one
A to grab valve oil cylinder, oil cylinder end and the gripping apparatus seat for grabbing valve oil cylinder are hinged, and the tailpiece of the piston rod for grabbing valve oil cylinder is cut with scissors with the middle part for grabbing valve oil cylinder
It connects.
As a preference, it is eight that multi-disc, which grabs valve, when gripping apparatus collapses, eight lower ends for grabbing valve are gathered in same center
Point.
Compared with prior art, the utility model has the beneficial effects that
The utility model band has the advantage that with the dumper that vehicle is grabbed
1, with vehicle grapple structure, its main structure is between driver's cabin and self-discharging carriage under collapsed state, and with vehicle grapple
The component of the left and right sides of structure without departing from the width of vehicle body, allow with vehicle grapple structure under collapsed state dumper directly into
Row self-unloading operation improves self-unloading operating efficiency；
2, left support leg, the pressure sensor in right support leg provide electric signal to unloading electromagnetic valve, unloading electromagnetic valve pair
Safeguard protection is played the role of in the movement of host computer valve group, realizes the function of dumper anti-rollover, and object safety coefficient is grabbed in raising；
3, it is in latch segment under locking state in anti-drop device to be located in card slot, locking pin locks the neck of latch segment, lock
One end and convex block for tightly selling are located at the two sides up and down of the neck of latch segment, realize manual locking function, under emergency case,
Such as zig zag, rollover, when shock, anti-drop device will not be opened voluntarily by impact, prevent secondary injury, improve traveling
Security performance；
4, the valve of grabbing of gripping apparatus is provided with eight, improves grasp force and grasp stability, and the every inside for grabbing valve is set
It is equipped with one and grabs valve oil cylinder, protect and grab valve oil cylinder, improve gripping apparatus service life.
Therefore the dumper grabbed with vehicle of the utility model band have improve self-unloading operating efficiency, improve grab object safety coefficient,
It improves driving safety performance, improve the advantages of gripping apparatus service life.
