With scientific and reasonable structure design and relatively high innovativeness, the novel anti-explosion crane trolley provided by the utility model has the advantages of simple structure, easiness in production, convenience in assembly, wide application range, small size, light weight, relatively great lifting weight and the like, and is suitable for a plant with a narrow structure.
Description
Technical field
The utility model belongs to lifting equipment field, particularly a kind of new type explosion proof crane carriage.
Background technology
Overhead explosion-proof crane is a kind of being widely used in to have the weight-lifting equipment under risk environment condition, and explosion-proof crane carriage is a vitals on overhead explosion-proof crane.At present, the hoisting capacity of overhead explosion-proof crane is mostly smaller, and explosive-proof grade is also lower, and the overhead explosion-proof crane that can reach d II CT4 is rarer.Particularly traditional explosion-proof crane carriage adopts two retarders more, increased the layout difficulty of lifting mechanism, increased weight and the scantling of structure of trolley frame, not only the corresponding hoisting capacity that reduced, at environment such as the narrow and small factory building of structure, storehouse, workshops, its applicability is also poor; And traditional explosion-proof crane trolley frame, mostly also is by board material splice or by shaped steel and board material splice and forms, manufacture craft is loaded down with trivial details, assembling trouble.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, make easily, assemble the new type explosion proof crane carriage of easy, to reduce vehicle body deadweight and overall dimensions.
The technical scheme that the utility model is realized its object is:
A kind of new type explosion proof crane carriage, it is characterized in that: by trolley frame, wheeling mechanism, braking motor, fixed pulley, reel and retarder, formed, trolley frame bottom installation carriage operating unit, braking motor and reel are all horizontally installed in the top of trolley frame, retarder is installed on the trolley frame of braking motor and the longitudinal side of reel, on the trolley frame between reel and braking motor, fixed pulley is installed.
And described trolley frame is fixedly mounted with and is formed by two box type girders and two box end carriages, between girder and end carriage, adopt high strength bolt to be connected.
And described box type girder and box end carriage form by top board, base plate and two risers.
And, described fixed pulley consists of two fixed pulleys and a leading sheave, two fixed pulley symmetries are installed on the mount pad of reel inner side, and leading sheave is installed between two fixed pulleys, and leading sheave is installed in the linear axis bearing being packed on mount pad by erecting frame and gudgeon.
Advantage of the present utility model and good effect are:
1, this new type explosion proof crane carriage, braking motor and reel are all horizontally installed in the top of trolley frame, retarder is installed on the trolley frame of braking motor and the longitudinal side of reel, thereby making braking motor, retarder and reel be C font arranges, only has one group of retarder, reduce the layout difficulty of lifting mechanism, reduced the scantling of structure of dolly.
2, this new type explosion proof crane carriage, the four beam spatial structures for consisting of two box type girders and two box end carriages, make its load distincter, between girder and end carriage, adopt high strength bolt to be connected, easy to assembly.
3, this new type explosion proof crane carriage, fixed pulley is placed between reel and braking motor, has reduced the mechanism size of trolley frame, and leading sheave can be adjusted automatically, guarantee steel rope elevation angle, and then guarantee the limes superiors of suspension hook, reduce the scantling of structure of dolly, reduce whole dolly deadweight.
4, the utility model scientific structure design is reasonable, have simple in structure, make and to fill the advantages such as easy, easy to assembly, applied widely, size is little, lightweight, hoisting capacity is larger, the factory building that commensurate structure is narrow and small is a kind of new type explosion proof crane carriage with higher innovation.

The specific embodiment
For further understanding content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows.It should be noted that, the present embodiment is descriptive, is not determinate, can not limit thus protection domain of the present utility model.
A kind of new type explosion proof crane carriage, it is comprised of trolley frame, wheeling mechanism 3, braking motor 4, fixed pulley, reel 6 and retarder 7, trolley frame bottom installation carriage operating unit, braking motor and reel are all horizontally installed in the top of trolley frame, retarder is installed on the trolley frame of braking motor and the longitudinal side of reel, on the trolley frame between reel and braking motor, fixed pulley is installed.
Trolley frame is fixedly mounted with and is formed by two box type girders 2 and two box end carriages 1, between girder and end carriage, adopts high strength bolt to be connected.Box type girder and box end carriage form by top board 13, base plate 15 and two risers 14.Four girder construction loads of trolley frame are distincter, easy to assembly.
Fixed pulley consists of two fixed pulleys 5 and a leading sheave 11, two fixed pulley symmetries are installed on the mount pad 12 of reel inner side, leading sheave is installed between two fixed pulleys, and leading sheave is installed in the linear axis bearing being packed on mount pad by erecting frame 16 and gudgeon 10.The gudgeon of leading sheave can be along axis oscillating, and pivot angle can be adjusted automatically with the position that hoists of weight, can guarantee that steel rope 9 rope stretching angles are not more than 3.5 °, and then the lifting limes superiors of lifting hook 8.
Principle of work of the present utility model is:
By the utility model assembling in orbit, during lifting workpiece, workpiece suspension, on suspension hook, is started to braking motor, motor drives retarder and then is with movable reel, steel rope, suspension hook, can realize lifting and the movement of workpiece.Because the utility model the utility model trolley frame is four beam spatial structures, between the beam of main side, bolt connects, and only has one group of retarder, simple in structure, makes easily, easy to assembly; Moreover the utility model fixed pulley is arranged between reel and braking motor, reduced the mechanism size of trolley frame, applicable to less space, Applicable scope is wider, has alleviated dead weight simultaneously, relatively can increase lifting weight; Also because the gudgeon of its leading sheave of fixed pulley of the present utility model can be along axis oscillating, can automatic adjusting position, guarantee that steel rope rope stretching angle is not more than 3.5 °, has effectively promoted the lifting limes superiors of suspension hook.
