By using the lorry-mounted crane special for railways, the working efficiency is improved, the working height is increased, and operation is convenient.
Description
Technical field
The present invention relates to the special lorry-mounted crane of a kind of railway, be specially the lorry-mounted crane that railway electrification section uses.
Background technology
Existing rolling stock lorry-mounted crane, is generally telescopic arm structure, first need raise arm during lifting, until suspension hook moves to after above weight, falling suspension hook could lift by crane.At railway electrification section, above circuit, there is contact system, raise arm and be easy to encounter contact system, thus get an electric shock, therefore raise the restriction of arm angle by contact system, arm can not be raised too high; Lifting part in hoisting crane front end is provided with the assemblies such as steel rope, assembly pulley, suspension hook, takies appreciiable space vertical, thus makes suspension hook ground height comparatively near, lifting limited space.Above-mentioned situation determines hoisting crane can not lift by crane in-plant weight, weight can not be hung required height and suitable position.
Mostly existing lorry-mounted crane is to utilize steel rope to lift by crane, and the weight that steel rope is sling produces uncontrollable slosh because of the impact of inertia and wind-force, therefore lifting poor stability.
Design regulation specifies, when telehoist lift heavy exceedes 70% of rated load, can not be with to carry and stretch.When lifting operation, sometimes need lifting weight could be hung to desired position several times, processing safety is not high, and operation is wasted time and energy.
In sum, there is potential safety hazard, operation inconvenience, repeatedly lift in traditional crane hanging component operation, efficiency is not high and can not lift by crane the situation of vehicles for close-distance heavy things, cannot meet the needs of electrified section line construction.
Summary of the invention
The object of the present invention is to provide the special lorry-mounted crane of a kind of railway, solve electrified section crane job scope little, there is the problem that potential safety hazard, operation inconvenience, efficiency are not high, can not lift by crane vehicles for close-distance heavy things.
Technical program of the present invention lies in: comprise a rotary table be connected with car body; Rotary table is provided with turntable.
Turntable top is connected with crane arm; Crane arm comprise be connected with turntable pivot arm, be loaded on the telescopic boom that can stretch out along pivot arm in pivot arm; The outer end of telescopic boom is connected with suspension hook support arm; Suspension hook support arm bottom is connected with far-end suspension hook.
Be provided with between pivot arm and turntable promote pivot arm rotate platform rotate telescopic oil cylinder; Pivot arm bottom is provided with the slideway parallel with pivot arm; Electric block is loaded in slideway and also can rolls along slideway; Electric block bottom is connected with near-end suspension hook.
Described suspension hook support arm is loaded on telescopic boom outer end through mount pad; Described Connection Block comprises the two pieces of adapter plates be parallel to each other be loaded on telescopic boom; Between two adapter plates, installation shaft is housed; Suspension hook support arm is loaded on installation shaft and can rotates along installation shaft; Suspension hook support arm is provided with knock hole, and adapter plate is provided with multiple mounting hole, and alignment pin is loaded in the knock hole on suspension hook support arm through one of them mounting hole.
The present invention is arranged on rolling stock, for construction of railways and safeguard in needed for material, instrument, equipment loading and unloading operation.Solve the problem that lifting operation generally need raise arm, during lifting, weight directly hangs on the far-end suspension hook of suspension hook support arm, be with arbitrarily to carry by crane arm and stretch, weight is hung to desired position, simultaneously under electric block with near-end suspension hook, electric block moves to above weight and directly lifts by crane, and realizes closely lifting operation, level of operation scope non-blind area; Do not need to rely on steel rope lifting, weight shake is little, can be with arbitrarily to carry and stretch, avoid repeatedly lifting, improve operating efficiency, add operation height, easy and simple to handle.

Detailed description of the invention
In Fig. 1, Fig. 2, crane arm 3 one end and turntable 7 hinged.Crane arm 3 comprise be connected with turntable 7 pivot arm, be loaded on the telescopic boom that can stretch out along pivot arm in pivot arm.Telescopic oil cylinder 6 one end is contained on turntable 7, and one end is contained in pivot arm lower end, rotates around hinge in order to control pivot arm.Telescopic boom outer end is connected with suspension hook support arm 1.Suspension hook support arm 1 is loaded on telescopic boom outer end through mount pad; Described Connection Block comprises the two pieces of adapter plates be parallel to each other be loaded on telescopic boom; Between two adapter plates, installation shaft is housed; Suspension hook support arm 1 is loaded on installation shaft and can rotates along installation shaft; Suspension hook support arm 1 is provided with knock hole, and adapter plate is provided with multiple mounting hole, and alignment pin is loaded in the knock hole on suspension hook support arm 1 through one of them mounting hole.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 with arbitrarily to carry and stretches, weight is hung to desired position by crane arm 3.Lifting part does not have steel rope, assembly pulley etc., on vertical, save space.
Crane arm is welded with slideway 23 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 and directly lifts by crane, and realizes 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 around axle central rotation.Turntable 7 and crane arm 3 grade that it is installed all rotate 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 directly hangs on the far-end suspension hook of suspension hook support arm 1, do not need to rely on steel rope lifting, crane arm can be with arbitrarily to carry and stretch, and weight is hung to desired position, avoids repeatedly lifting by crane, easy and simple to handle.
Crane arm 3 can bad-looking arm hoisting heavy, hangs loads and directly hangs on far-end suspension hook, does not need to rely on steel rope lifting, and weight shake is little, improves operating efficiency, adds operation height, bad-looking arm, and the weight that distance line is nearer simultaneously also can lift by crane.
In Fig. 4, when cargo platform 9 handling tool 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 crane arm 3 times welding, and 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, lifts by crane in scope at electric block 4, and the near-end suspension hook 5 of electric block 4 can be utilized to lift by crane.Achieve closely lifting operation, solve current luffing and must raise arm, raise arm and can touch contact system thus the problem of getting an electric shock, level of operation scope non-blind area.
