Description
Technical field
The utility model belongs to counter weight device technical field, is specifically a kind of collapsible additional counter weight device.
Background technology
Minor crane is a kind of haulage vehicle that small-sized crane and chassis are combined, and is by crane arm, turntable, machine
The part such as frame, supporting leg is constituted, and the mechanical action of telpher is realized by the action of the mechanisms such as luffing, flexible, revolution, elevator,
Hoisting operation is realized by the combination of different actions, is widely used in construction site, industrial and mining enterprises, station, harbour, electric power, postal
Political affairs, urban construction, gardens, the fields such as bridge formation of paving the way.Traditional minor crane resistance to capsizing is weak, when need aggravate counter weight device
When, tedious process and coordinate poor with former crane rotation platform, easily there is potential safety hazard, the safety of workmen cannot
Ensure.
The content of the invention
It is to solve traditional crane when needing to aggravate counter weight device, tedious process and matches somebody with somebody with former crane rotation platform
Close poor, there is the technical problem of potential safety hazard, the utility model provides a kind of collapsible additional counter weight device.
The technical solution adopted in the utility model is：
A kind of collapsible additional counter weight device, including fixed ear base and tray supporter, it is characterised in that the fixed ear base
The rear end of oil cylinder is connected with middle insertion front end bearing pin, the front end bearing pin, the front end of the oil cylinder is connected with rear end bearing pin, institute
The piston rod front end for stating oil cylinder is connected with the swing arm of rotating shaft；The tray supporter is connected with pallet, the support by the rotating shaft
Some self-balanced upper rotaries are placed with disk.
Further, the self-balanced upper rotary is concrete segment, and quantity is 2-6, and the quality of each self-balanced upper rotary is
100KG-250KG。
The beneficial effects of the utility model are：
1st, the utility model is fixed on crane rotation platform by fixed ear base and tray supporter, with crane rotation platform
Between work good.
2nd, the utility model realizes the folding of counter weight device using oil cylinder and stretched that hydraulic control operation is flexible, no machinery
Impact.
3rd, self-balanced upper rotary of the present utility model is concrete segment, convenient to make, and self-balanced upper rotary is reduced by increasing
Quantity can just change balance weight so that change crane work when resistance to capsizing.
Brief description of the drawings
Fig. 1 is the front view of the utility model structural representation；
Fig. 2 is the top view of the utility model structural representation.
Each part mark is as follows in accompanying drawing：1st, fixed ear base, 2, front end bearing pin, 3, oil cylinder, 4, rear end bearing pin, 5, rotating shaft,
6th, pallet, 7, self-balanced upper rotary, 8, tray supporter.
Embodiment
The technical scheme in the utility model embodiment is clearly and completely described below in conjunction with accompanying drawing：
As illustrated, a kind of collapsible additional counter weight device, including the fixed ear base 1 below crane rotation platform
With tray supporter 8, fixed ear base 1 inserts on front end bearing pin 2, front end bearing pin 2 rear end for connecting oil cylinder 3, the front end connection of oil cylinder 3
There is rear end bearing pin 4, the piston rod front end of oil cylinder 3 is connected with the swing arm of rotating shaft 5；Tray supporter 8 is connected with pallet 6 by rotating shaft 5,
Two self-balanced upper rotaries 7 are placed with pallet 6, each self-balanced upper rotary 7 is quality 250KG concrete segment.
A kind of collapsible additional counter weight device of the utility model operationally, passes through fixed ear base 1 and tray supporter 8 respectively
It is fixed on below crane rotation platform and side, front end bearing pin 2, oil cylinder 3, the and of rear end bearing pin 4 is sequentially installed with fixed ear base 1
The swing arm of rotating shaft 5, tray supporter 8 passes through the connecting trays 6 of rotating shaft 5.Flexible by oil cylinder 3 can drive the swing arm of rotating shaft 5, turn
The rotation of axle 5 can realize folding and the opening of pallet 6, be matched somebody with somebody by adding assembly and disassembly self-balanced upper rotary 7 to realize to increased or decrease
Weight, so that resistance to capsizing when changing crane work.
A kind of collapsible additional counter weight device of the utility model can realize all-hydraulic control with secure attachment on crane
System, manoeuvrable, no mechanical shock；Additional bob-weight is realized, resistance to capsizing when increasing crane work；Self-balanced upper rotary
Made for concrete segment is convenient, conveniently remove and unload, be adapted to use in minor crane.
