Description
Technical field
The utility model relates to a kind of elevator machinery, is specifically related to a kind of specialized subway equipment loading and unloading and maintenance activity hoisting crane.
Background technology
At present, known hoisting crane structure is comprised of hoisting crane bridge, traveling mechanism of the larger traveller, wheeling mechanism, electrical equipment.Crane span structure adopts box-shaped, truss welding structure, and traveling mechanism of the larger traveller, wheeling mechanism adopt motor to drive respectively.Cost is high, maintenance cost is high, use cost is high, dismounting, transportation difficulty, in certain space, be difficult to satisfy high efficiency, job requirements easily, in subway equipment loading and unloading and maintenance activity, because limited space, can't high efficiency, easily operation.
The utility model content
It is high that the purpose of the utility model technology is to overcome existing hoisting crane cost, dismounting, transportation, the restricted difficulty of working space, the deficiency that can not satisfy the loading and unloading of subway equipment and keep in repair high-efficiency homework in finite space.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of subway special purpose crane of repairing comprises girder, fixed pulley, the axis hole of wearing for subsequent use, rope plug for subsequent use, electrically driven treadmill, suspender, supporting leg, electric block is characterized in that, described girder adopts the deformed steel welding, and the girder both sides are provided with fixedly that the axle of wearing of fixed pulley reaches the fixedly rope plug of steel rope; Be provided with for subsequent use wear axis hole and for subsequent use rope plug toward girder span center direction every a segment distance from the described axle of wearing, described distance and quantity and specification of wearing axis hole, rope plug for subsequent use for subsequent use arrange according to actual needs; The described axis hole of wearing for subsequent use is used for holding wearing axle, and described rope plug for subsequent use is used for fixedly steel rope; Respectively have steel-wire rope type electric block on the grade beam in the middle of the supporting leg of girder both sides, be provided with in addition electrically driven treadmill on the girder, the electrically driven treadmill below is provided with the lifting nose, and described lifting nose can hang chain block, ring-chain hoist or cat head and hang; Described girder below is by the wire rope hanging suspender, described steel rope one end be fixed on the girder rope beyond the Great Wall, the other end is walked around the movable pulley of fixed pulley and suspender top, is connected on the electric block; Described girder and supporting leg are with bolts.
Principle of work of the present invention: owing to be provided with axis hole and the rope plug for subsequent use worn for subsequent use, so wear the position of axle and rope plug according to the length size adjusting of suspender, thereby in operation, steel rope is remained on vertical direction as much as possible, on hoisting depth, can reach desirable effect.And general hoisting crane in this respect since when hoisting steel rope the angle restriction is arranged, be difficult to satisfy desirable lifting altitude.When needs lifting or maintenance rail, start steel-wire rope type electric block and make suspender drop to correct position, carry out construction operation by steel-wire rope type electric block and fixed pulley.When needs liftings miscellaneous equipment, suspender is removed, hang chain block or ring-chain hoist at electrically driven treadmill, cat head hangs, and starts electrically driven treadmill, carries out construction operation.
Compared with prior art, the beneficial effects of the utility model are: the subway special purpose crane of repairing of the present utility model is specifically designed to subway construction, subway maintenance of equipment, loading and unloading operation, this hoisting crane is simple because of its manufacture craft, it is little to occupy the space, has reached then that use cost is low, cost is low, is easy to dismounting, the purpose of flexible operation.That this hoisting crane has is convenient to operation, simple in structure, dismounting flexibly, be easy to transportation, handling efficiency is high, maintenance cost is low, use cost is low and the easy-to-operate characteristics, under limited space condition, can convenient, high efficiency construction operation, be convenient to install and transportation.
Description of drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is lateral plan of the present utility model.
Wherein each Reference numeral is: 1-girder, 2-fixed pulley, the 3-axis hole of wearing for subsequent use, 4-rope plug for subsequent use, 5-electrically driven treadmill, 6-suspender, 7-tunnel circumference, 8-supporting leg, 9-electric block.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
Referring to Fig. 1, Fig. 2, a kind of subway special purpose crane of repairing comprises girder 1, fixed pulley 2, the axis hole 3 of wearing for subsequent use, rope plug 4 for subsequent use, electrically driven treadmill 5, suspender 6, supporting leg 8, electric block 9.Crane girder 1 adopts the deformed steel welding, and the tonnage of described girder, span, cantilever, rising etc. can customize by customer requirements.Girder 1 both sides are provided with fixedly, and the axle of wearing of fixed pulley 2 reaches the fixedly rope plug of steel rope, far respectively have three for subsequent use wear axis hole 3 and three for subsequent use rope plugs 4 toward girder span center direction every 200mm from the described axle of wearing, described spacing distance and quantity and specification of wearing axis hole, rope plug for subsequent use for subsequent use can adjust accordingly according to suspender length size, the described axis hole of wearing for subsequent use is used for holding wearing axle, and described rope plug for subsequent use is used for fixedly steel rope.Respectively have CD3T shaped steel wire rope electric block 9 traction weights on the grade beam in the middle of the supporting leg 8 of girder both sides, described steel-wire rope type electric block can be changed according to lift heavy.Be provided with in addition 10T (tonnage can be equipped with according to the girder bearing capacity) electrically driven treadmill 5 on the girder 1, electrically driven treadmill 5 belows are provided with lifting nose (not shown), can hang as required chain block, ring-chain hoist, cat head and lift up into capable equipment hoisting inspection, maintenance.Described girder below is by wire rope hanging suspender 6, described steel rope one end be fixed on the girder rope beyond the Great Wall, walk around the movable pulley of fixed pulley, suspender top, the other end is connected on the electric block 9.Because be provided with axis hole and the rope plug for subsequent use worn for subsequent use, thus the position of axle and rope plug worn according to the length size adjusting of suspender, thus in operation, steel rope is remained on vertical direction as much as possible, on hoisting depth, can reach desirable effect.And general hoisting crane in this respect since when hoisting steel rope the angle restriction is arranged, be difficult to satisfy desirable lifting altitude.Girder 1 and supporting leg 8 with bolts being convenient to are dismantled.
When needs lifting or maintenance rail, start steel-wire rope type electric block 9 and make suspender 6 drop to correct position, carry out construction operation by steel-wire rope type electric block 9 and fixed pulley 2.When needs liftings miscellaneous equipment, suspender 6 is removed, hang chain block or ring-chain hoist at electrically driven treadmill 5, cat head hangs, and starts electrically driven treadmill, carries out construction operation.
