Abstract
The utility model discloses a combined type cable loop wheel machine suitable for installation of large-span arched bridge multisection section arch rib (strength nature skeleton) installation or cable-stay bridge girder erection joint usefulness comprises hoist and mount part and anchor buckle part, and the cable tower hinge of cable loop wheel machine is on anchor tower (mound), and the knot cable and the anchor rope of anchor buckle part are alternately anchored on the anchor case at anchor tower (mound) top, utilize jack adjustment pulling force, make the horizontal resultant force of knot cable and anchor rope approach to zero. The utility model has the characteristics of construction convenient operation, the security is high, and the engineering progress is fast, and is with low costs, and the transparency is strong under specific topography condition.
Description
The utility model relates to a kind of construction implement, the particularly a kind of multi-segmental arch rib (stiff skeleton) of long-span arch bridge, cable stayed bridge or combined type cable crane that the girder cantilever is installed of being applicable to.
The multi-segmental arch rib (stiff skeleton) of existing long-span arch bridge or the segmentation cantilever of cable-stayed bridge main-beam are installed, when constructing with cable crane, and lifting and button anchor system, adopt two independently mechanism's work, complex structure, cost height, especially when orographic condition did not allow, it was big to implement difficulty.
Goal of the invention of the present utility model is intended to overcome above-mentioned shortcoming, for specific orographic condition provides a kind of combined type cable crane that is applicable to that long-span arch bridge multi-segmental arch rib (stiff skeleton) or cable-stayed bridge main-beam cantilever are installed.
Goal of the invention of the present utility model is achieved in that the utility model is made up of handling mechanism and anchor deduction structure, handling mechanism includes Sarasota, is erected at the main rope on the Sarasota, regulate the anchorage that the main rope elevation plays the pulling force balanced action, coaster and the coaster of frame on main rope plays hoist cable and suspender, and drags drag cable and lifting tractor that coaster moves on main rope; Anchor deduction structure includes anchor tower (pier), and the anchor cable, knotted rope, jack, the oil pump that are erected at the anchor tower top have reached the anchorage of pulling force balanced action; Of the present utility model being characterised in that: Sarasota is located on the anchor tower by hinge knot mechanism rack, makes handling and anchor button two mechanisms form one, and the knotted rope on anchor tower pushes up and anchor cable intersect with steel strand or high-strength steel tow on the anchor case that is anchored at the anchor tower top.
The utility model is owing to transmit axial compression to anchor tower (pier) by hinge knot mechanism, and Sarasota does not bear moment of flexure.Knotted rope, anchor cable intersection are anchored on the anchor case on anchor tower (pier) top, utilize jack and oil pump to adjust the pulling force of knotted rope anchor cable, make the horizontal resultant of knotted rope and anchor cable level off to zero, the anchor case horizontal movement on anchor tower (pier) top is corresponding to level off to zero, by progressively putting the elevation that arch rib (stiff skeleton) or girder sections have been pieced together in a knotted rope and anchor cable adjustment.
The utility model is at the sections quantity of multi-segmental cantilever arch rib (stiff skeleton) or girder and the quantity and the Suo Li of lifting weight configuration knotted rope and anchor cable.
The utility model can be installed the multi-segmental arch rib (stiff skeleton) of arch bridge or the multi-segmental girder of cable stayed bridge by cantilever under the state of not establishing any horizontal guy.Especially under specific orographic condition, constructing operation is simple, and good stability is safe, and programming is fast, and the duration is short, and cost is low.
Provide accompanying drawing of the present utility model below:
Fig. 1 is a work schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model is made up of handling mechanism 1 and anchor deduction structure 2, and handling mechanism 1 comprises anchorage 3, Sarasota 4, main rope 5, suspender 6, coaster 7, drag cable 8, plays hoist cable 9, lifting tractor; Anchor deduction structure 2 comprises anchorage 3, knotted rope 10, anchor cable 11, anchor tower (pier) 12, jack 13, oil pump 14.The major function of handling mechanism 1 is the lifting member, vertical lift and vertically moving; The function of anchor deduction structure is to form dynamic equilibrium anchor button system with assembling members sections, closes up until arch rib (stiff skeleton) or girder.Of the present utility model being characterised in that: Sarasota 4 is erected on the anchor tower 12 by hinge knot mechanism 15, make 2 liang of mechanisms of handling and anchor button form one, the knotted rope 10 on anchor tower 12 tops intersects with anchor cable 11 usefulness steel strand or high-strength steel tow and is anchored on the anchor case at anchor tower 12 tops.Transmit axial compression to anchor tower (pier) 12 by hinge knot mechanism 15, Sarasota 4 does not bear moment of flexure; Knotted rope 10, anchor cable 11 adopt steel strand or high-strength steel tow, intersect and be anchored on the anchor case on anchor tower (pier) 12 tops, utilize jack 13 to adjust the pulling force of knotted rope 10, anchor cable 11, make the horizontal resultant of knotted rope 10 and anchor cable 11 level off to zero, the anchor case horizontal movement at anchor tower 12 (pier) top is corresponding to level off to zero, adjusts the elevation of piecing together arch rib (stiff skeleton) or girder sections by progressively putting a knotted rope 10 and anchor cable 11.(1#-18#) installs piecemeal from arch springing to vault as Fig. 1, the two sides symmetry is carried out, per 3 sections is one group, lift every group the interim fixing cable anchoring of the first two section skeleton, after lifting the 3rd section skeleton one group of fixedly knotted rope and anchor cable are installed, and remove interim knotted rope, utilize 13 stretch-draw of button anchorage cable stretching jack fixedly knotted rope 10 and anchor cable 11, adjust each section of skeleton elevation, up to installation final stage (18#), span centre close up and stressed after, symmetrical equilibrium ground, two sides loosens knotted rope 10 and anchor cable 11 by designing requirement, removes fully until knotted rope 10 and anchor cable 11, use of the present utility model, finished 2191 tons of skeleton liftings of 36 sections work in 50 days smoothly, every section weighs 61 tons, does not establish any horizontal guy.
The utility model constructing operation is convenient, is easy to control, and is safe, good stability, and programming is fast, and cost is low, and applicability is strong.
