Abstract
The utility model relates to a two-way construction flat bridge with a telescopic and rotary extending arm. A rotary device is arranged on a flat bridge tower body, the extending arms of the flat bridge at two sides of the tower body are in synchronous rotation with the rotary device. The extending arms of the flat bridge consists of a fixing section, a standard section and a telescopic section, the change of the length of the extending arm of the flat bridge can be realized by the extending of the telescopic section and the disassembly and assembly of the standard section.
Description
Affiliated technical field
The utility model relate to a kind of building operation with hydraulic lifting is scalable can rotating two-way construction level bridge.
Background technology
At present, known power plant cooling water tower construction adopts the unidirectional level bridge of fixed type, tower crane and construction elevator mode to solve construction material and personnel's vertical transport.This kind construction method direct cost and indirect cost are bigger, and when the cooling tower bodily form is big, for satisfying the covering of power energy, need to arrange some fixedly level bridge systems, and the management of construction and coordination have big difficult.
Summary of the invention
In order to overcome the demand of the covering large cooling tower construction scope inner working face that existing fixed level bridge system can not economical rationality, the utility model provides a kind of level bridge system that turns round, this level bridge system can not only realize from jacking, and level bridge semi-girder 360 ° of revolutions easily, horizontal direction is scalable, satisfies different level, the cooling tower construction of different radii, improve operating efficiency greatly, reduce construction cost.
The technical scheme that its technical matters that solves the utility model adopts is: arrange the jacking stock on level bridge system vertical tower, jacking stock top is provided with rotary disk (swing type mechanism), the level bridge semi-girder is arranged in the body of the tower both sides, two level bridge semi-girders are on same straight line, and level bridge semi-girder and rotary disk are articulated and connected.Level bridge body of the tower internal placement cargo transport cage, people's goods elevator is adhered in the level bridge body of the tower outside, and the level bridge top is provided with tower crane and gin pole, and level bridge semi-girder root is arranged the concrete aggregate bucket, and the goods and materials such as cement concrete in the shipping cage are transported in the semi-girder aggregate bin.The level bridge semi-girder be divided into fixed knot, detachably the joint and slip joint, the level bridge boom reach can be regulated.The level bridge system carries out jacking by the jacking stock, can satisfy the construction of different level.The semi-girder of level bridge can be realized 360 ° revolution by rotary disk, satisfies the construction of varying level position.The required cement concretes of structure construction etc. are transported to level bridge semi-girder position by the inner cage of body of the tower, and the workmen enters in the level bridge semi-girder by the people's goods elevator attached to the body of the tower outside.
The jacking stock cooperates with the revolution semi-girder, makes the level bridge system can satisfy in the system capability, any absolute altitude, the construction material of any level attitude, workmen's transportation problem.
The beneficial effects of the utility model are can only arrange a level bridge system in large cooling column inside, body of the tower both sides level bridge semi-girder stress balance (balance of axle power, shearing, moment of flexure).The level bridge system can carry out the transportation of vertical transport and level easily, mechanical less investment, and the operating efficiency height, the total cost input is lower, construction safety reliability height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is unitary construction figure of the present utility model.
Fig. 2 is level bridge jacking supernumerary segment figure.
Fig. 3 is the flexible figure of level bridge telescopic boom.
Fig. 4 is level bridge standard arm dismounting figure.
Fig. 5 is the short status figure of level bridge semi-girder.
1. bases among the figure, 2. body of the tower, 3. building hoist, 4. jacking stock, 5. cage winch, 6. level bridge turning gear, 7. concrete aggregate bucket, 8. cage, 9. level bridge tower cap, 10. level bridge telescopic boom, 11. level bridge standard arm 1,12. level bridge standard arm 2,13. level bridge fixed arms, 14. the lifting dead man, 15. level bridge drag-lines, 1,16. level bridge drag- line 2,17. level bridge drag- line 3,18. level bridge drag- lines 4,19. body of the tower standard knots.
The specific embodiment
In Fig. 2, lifting dead man (14) is transported to body of the tower standard knot (19) in the jacking stock (4), and jacking stock (4) docks body of the tower standard knot (19) firmly with body of the tower (2), finishes the jacking process.Repeat this jacking process, level bridge progressively can be raise.
In Fig. 1, the workmen enters on the level bridge fixed arm (13) by building hoist (3), construction is transported on the level bridge fixed arm (13) by lifting dead man (14) with materials such as reinforcing bar templates, by manual type the construction material level is transported to desired location again.Cement concrete is by being arranged in body of the tower (2) in-to-in cage (8), be transported to concrete aggregate bucket (7) top, cement concrete in the cage (8) is put into concrete aggregate bucket (7), and concrete aggregate bucket (7) is put into the hand barrow of its below with cement concrete, manually is transported to and need uses the position.After place concreting finishes, drive the level bridge semi-girder by level bridge turning gear (6) and rotate in the horizontal direction, make semi-girder go to new driving surface, continue to finish concreting work.
When the distance of construction working face on a certain elevation diminishes with body of the tower (2) distance, as the construction of power-plant cooling water tower, with 0～10m in level bridge telescopic boom (10) the retraction level bridge standard arm 1 (11) among Fig. 3, to satisfy construction requirement.When the distance of the distance of construction working face and body of the tower (2) further diminishes, figure with level bridge telescopic boom (10) retraction level bridge standard arm 2 (12) in, unclamp level bridge drag-line 1 (15), remove level bridge standard arm 1 (11).After finishing above-mentioned steps, level bridge telescopic boom (10) is stretched out level bridge standard arm 2 (12) 0～10m, to satisfy construction requirement.Repeat above-mentioned steps, the shortest all level bridge standard arms can dismountings in level bridge telescopic boom (10) retraction level bridge fixed arm (13), makes the horizontal length of level bridge the shortest.
