Description
Technical field
The present invention relates to a kind of special lorry-mounted crane of railway, the lorry-mounted crane that specially railway electrification section uses.
Background technology
Existing rolling stock lorry-mounted crane, generally telescopic arm structure, need to first raise arm during lifting, until after suspension hook moves to above weight, falling suspension hook could lift by crane.At railway electrification section, above circuit, there is contact net, raise arm and be easy to encounter contact net, thus get an electric shock, therefore raise arm angle and limited by contact net, it is impossible to raise arm the highest；Lifting part in crane front end is provided with the assemblies such as steel wire rope, assembly pulley, suspension hook, takies considerable space vertical, so that suspension hook ground height is relatively near, lifts by crane limited space.Above-mentioned situation determines crane can not lift by crane in-plant weight, and weight can not hang required height and suitable position.
Mostly existing lorry-mounted crane is to utilize steel wire rope to lift by crane, and the weight that steel wire rope is sling produces uncontrollable slosh because of the impact of inertia and wind-force, therefore lifts by crane poor stability.
Design specification specifies, when telehoist lift heavy exceedes the 70% of rated load, it is impossible to band carries flexible.When lifting operation, it is sometimes desirable to weight could be hung desired position by lifting several times, and processing safety is the highest, and operation is wasted time and energy.
In sum, there is potential safety hazard, operation inconvenience, repeatedly lifting, inefficient and can not lift by crane the situation of vehicles for close-distance heavy things in traditional crane hanging component operation, it is impossible to meets the needs of electrified section line construction.
Summary of the invention
It is an object of the invention to provide a kind of special lorry-mounted crane of railway, electrified section crane job scope is little, there is potential safety hazard, operate problem inconvenient, inefficient, that can not lift by crane vehicles for close-distance heavy things in solution.
Technical program of the present invention lies in: include a rotary table being connected with car body；Rotary table is provided with turntable.
Turntable top connects crane arm；Crane arm includes the turning arm being connected with turntable, be loaded on turning arm in the telescopic arm that can stretch out along turning arm；The outer end of telescopic arm connects suspension hook support arm；Suspension hook support arm bottom connects far-end suspension hook.
The telescopic oil cylinder promoting turning arm to rotate it is provided with around turntable between turning arm and turntable；Turning arm bottom is provided with the slideway parallel with turning arm；Electric block is loaded in slideway and can roll along slideway；Electric block bottom connects near-end suspension hook.
Described suspension hook support arm is loaded on telescopic arm outer end through mounting seat；Described mounting seat includes be loaded on telescopic arm two pieces of installing plates being parallel to each other；Equipped with installing axle between two installing plates；Suspension hook support arm is loaded on installation axle and can rotate along installing axle；Suspension hook support arm is provided with hole, location, and installing plate is provided with multiple installing hole, and alignment pin passes through one of installing hole and is loaded in the hole, location on suspension hook support arm.
The present invention is arranged on rolling stock, the required material in construction of railways and maintenance, instrument, the handling operation of equipment.Solve the problem that lifting operation typically need to raise arm, during lifting, weight directly hangs on the far-end suspension hook of suspension hook support arm, carried flexible by any band of crane arm, weight is hung to desired position, simultaneously with near-end suspension hook under electric block, electric block moves to directly lift by crane above weight, it is achieved closely lifting operation, level of operation scope non-blind area；Needing not rely on steel wire rope lifting, weight shake is little, can arbitrarily carry flexible by band, it is to avoid repeatedly lift, improve working performance, add operation height, easy and simple to handle.

Detailed description of the invention
In Fig. 1, Fig. 2, crane arm 3 one end is hinged with turntable 7.Crane arm 3 includes the turning arm being connected with turntable 7, be loaded on turning arm in the telescopic arm that can stretch out along turning arm.Telescopic oil cylinder 6 one end is contained on turntable 7, and one end is contained in turning arm lower end, rotates around hinge in order to control turning arm.Telescopic arm outer end connects suspension hook support arm 1.Suspension hook support arm 1 is loaded on telescopic arm outer end through mounting seat；Described mounting seat includes be loaded on telescopic arm two pieces of installing plates being parallel to each other；Equipped with installing axle between two installing plates；Suspension hook support arm 1 is loaded on installation axle and can rotate along installing axle；Suspension hook support arm 1 is provided with hole, location, and installing plate is provided with multiple installing hole, and alignment pin passes through one of installing hole and is loaded in the hole, location on suspension hook support arm 1.Suspension hook support arm hangs with far-end suspension hook 1 time.
During lifting, weight directly hangs on the far-end suspension hook of suspension hook support arm 1, is carried by any band of crane arm 3 flexible, weight is hung to desired position.Lifting part does not has steel wire rope, assembly pulley etc., saves space on vertical.
Crane arm is welded with slideway 2 for 3 times, and electric block 4 can roll along slideway 2, electric block lower bands near-end suspension hook 5.Electric block 4 is movable to above weight directly lift by crane, it is achieved closely lifting operation, level of operation scope non-blind area.
Turntable 7 is fixed on rotary table 8, and rotary table 8 is fixed on vehicle frame 10, and rotary table 8 can be around axle central rotation.Turntable 7 and crane arm 3 grade installed on it all can be rotated by rotary table 8.
In Fig. 3, during the outer weight of lifting circuit, crane arm 3 by telescopic oil cylinder 6 flexible can around the hinge with turntable 7 upwards, be rotated down, the far-end suspension hook on suspension hook support arm 1 can direct hoisting heavy.Because weight is directly to hang on the far-end suspension hook of suspension hook support arm 1, it is not necessary to rely on steel wire rope lifting, crane arm can arbitrarily carry flexible by band, weight is hung to desired position, it is to avoid repeatedly lift by crane, easy and simple to handle.
Crane arm 3 can hang loads directly hang on far-end suspension hook with bad-looking arm hoisting heavy, it is not necessary to relying on steel wire rope lifting, weight shake is little, improves working performance, adds operation height, bad-looking arm, and the weight that distance line is nearer simultaneously can also lift by crane.
In Fig. 4, when cargo platform 9 handling instrument on vehicle frame 10 and equipment, electric block 4 directly can be made to slide into above instrument and equipment in the slideway 2 of 3 times welding of crane arm, near-end suspension hook 5 directly lifts by crane, and the position of instrument and equipment is unrestricted.
In Fig. 5, the goods that distance line is nearer, in the range of electric block 4 lifts by crane, the near-end suspension hook 5 of available electric block 4 lifts by crane.Achieve closely lifting operation, solve current luffing and must raise arm, raise arm and can touch contact net thus the problem got an electric shock, level of operation scope non-blind area.
