Background technology
Along with the development of society, hoisting crane serves requisite vital function in industrial development.Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Also known as crane.Current domestic each large lifting company cancellation lift heavy driving functions gradually.The principal feature of wheel-mounted crane is: its travel operator's compartment and lifting control cabin unites two into one, be developed by crawler crane to form, the crawler belt of traveling gear and mobile roof support part are become the chassis having tire, overcome the shortcoming that creeper tread of crawler crane road pavement damages, belong to material carrying machine.The work characteristics that weight-lifting equipment has does intermittent exercise, and namely in a working cycle, the corresponding mechanism of the action such as feeding, migration, unloading is alternation, hoisting crane development commercially and use more and more extensive.For ensure job safety, at present domestic substantially forbid not making a jack carry out lifting operation.
Often occur some accidents owing to travelling without supporting leg lift heavy and lift heavy, also comparatively crawler crane is fast for the speed of traveling; But must ensure that path formation is solid, tire pressure meets the requirements, hanging ground must not more than 50CM during walking; Forbid the long distance walking of on-load.For ensure job safety, at present domestic substantially forbid not making a jack carry out lifting operation.In order to solve the problems of the technologies described above, the invention provides a kind of span winch.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of span winch is provided, operation is stable, hoisting capacity large, can lift heavy walking in particular range, power is electrical motor, reliability, maintainability are all good, over-the-road expense is extremely low, moving velocity is slow, and off-road capability is good, and hill climbing ability is large, can the hover ground construction such as in muddy, marsh, lift heavy travels relatively more steady, and can change multiple equipment and carry out several work, range of use is wide, the operating efficiency of hoisting crane can be improved, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of span winch of the present invention, comprises driver's cab, Shears, pull bar, trunk beam, steel rope, suspension hook, combination jib, platform, rotary column, staggered form door frame and supporting leg; Described driver's cab top is provided with Shears and described driver's cab bottom is fixedly connected with platform; Described Shears one end is rotationally connected pull bar and described pull bar one end is provided with trunk beam; Described platform side is provided with combination jib; Described platform bottom is provided with rotary column and described rotary column one end is connected with staggered form door frame; Described staggered form door frame bottom is fixed with supporting leg.
Further, described combination jib one end and driver's cab close contact.
Further, described trunk beam one end is provided with steel rope.
Further, described steel rope one end is fixedly connected with suspension hook.
Further, described trunk beam is connected by steel rope with between suspension hook.
The beneficial effect that compared with prior art the present invention reaches is:
1, compact conformation of the present invention, operation is stable, hoisting capacity large, can lift heavy walking in particular range;
2, power of the present invention is electrical motor, and reliability, maintainability are all good, and over-the-road expense is extremely low;
3, moving velocity of the present invention is slow, and off-road capability is good, and hill climbing ability is large, can the hover ground construction such as in muddy, marsh;
4, cost of the present invention is low, is convenient to installation, good heat dissipation effect, long working life, can improve the operating efficiency of hoisting crane, has good economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification sheets, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.
In the accompanying drawings:
Fig. 1 is integral structure schematic diagram described in the embodiment of the present invention;
Number in the figure: 1, driver's cab; 2, Shears; 3, pull bar; 4, trunk beam; 5, steel rope; 6, suspension hook; 7, jib is combined; 8, platform; 9, rotary column; 10, staggered form door frame; 11, supporting leg.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Embodiment: as shown in Figure 1, comprises driver's cab 1, Shears 2, pull bar 3, trunk beam 4, steel rope 5, suspension hook 6, combination jib 7, platform 8, rotary column 9, staggered form door frame 10 and supporting leg 11; Described driver's cab 1 top is provided with Shears 2 and described driver's cab 1 bottom is fixedly connected with platform 8; Described Shears 2 one end is rotationally connected pull bar 3 and described pull bar 3 one end is provided with trunk beam 4; Described platform 8 side is provided with combination jib 7; Described platform 8 bottom is provided with rotary column 9 and described rotary column 9 one end is connected with staggered form door frame 10; Described staggered form door frame 10 bottom is fixed with supporting leg 11.
