Abstract
The lifting hold-fast body of the prefabricated pier of a kind of large-tonnage, it is characterized in that described lifting hold-fast body comprises the rectangular frame main body of a lifting setting, this rectangular frame main ring is horizontally disposed with around the prefabricated pier of vertical lifting, this rectangular frame main body surrounding distribution be fixed with positioning hydraulic cylinder, this positioning hydraulic cylinder along this rectangular frame main body to the inside the prefabricated pier of Level Promoting sidewall arrange.The lifting hold-fast body reasonable in design of the prefabricated pier of this large-tonnage, Hoisting Security stability are high, it effectively avoids prefabricated pier and hangs the problem producing in the process of supporting body and rock caused each suspension centre discontinuity, has stopped the unsafe factor lifted.
Description
Technical field
The utility model belongs to the lifting spacing equipment of precast pier body, and what prevent prefabricated pier from rocking when being specifically related to a kind of transhipment and lifting of large-tonnage Prefabricated integral pier hangs a hold-fast body.
Background technology
Along with the development of bridge and overhead road bridge technology, marine or become the important engineering of bridge construction across the overhead road bridge construction in waters.Due to viaduct many employings Steel Continuous Box beam bridge, the supporter of non-navigation bridge mostly is prefabricate and install pier structure, can be divided into overall pier, cushion cap adds lower joint pier shaft, middle joint pier shaft and upper joint pier shaft Four types by classification.Because the overall weight of prefabricated monolithic pier can reach 3000-5000 many tons, the pier of pier shaft bottom adopts back pouring hole design simultaneously, needs safety and the stability robust design of carrying out pier shaft and pier integral hoisting.
Existing Large-scale Hoisting arranges the lifting adopting upright monolithic to carry out prefabricated pier, but when prefabricated pier departs from supporting body, rocking of certain amplitude can occur, and this rocks and will have a strong impact on the stressed uniformity of each suspension centre, causes the stability of lifting and safety to reduce.
Utility model content
The utility model provides the lifting hold-fast body of a kind of reasonable in design, the prefabricated pier of large-tonnage that Hoisting Security stability is high, it effectively avoids prefabricated pier and hangs the problem producing in the process of supporting body and rock caused each suspension centre discontinuity, has stopped the unsafe factor lifted.
The technical scheme that the utility model adopts is as follows:
The lifting hold-fast body of the prefabricated pier of a kind of large-tonnage, it is characterized in that described lifting hold-fast body comprises the rectangular frame main body of a lifting setting, this rectangular frame main ring is horizontally disposed with around the prefabricated pier of vertical lifting, this rectangular frame main body surrounding distribution be fixed with positioning hydraulic cylinder, this positioning hydraulic cylinder along this rectangular frame main body to the inside the prefabricated pier of Level Promoting sidewall arrange.
Concretely, in described rectangular frame main body, distribution is provided with four Heave Heres that hoist cable connects this rectangular frame main body.
In one embodiment, in described rectangular frame main body, distribution is provided with four of connecting lifting pier cushion cap hoist cable and holds suspension centre.
In one embodiment, the cylinder body of hydraulic cylinder of transposing be fixedly installed in described rectangular frame main body, the telescopic hydraulic bar level of positioning hydraulic cylinder is arranged to pushing tow inside described rectangular frame main body.
In another embodiment, on the four edges frame of described rectangular frame main body, distribution is provided with two positioning hydraulic cylinders separately.
The lifting that the lifting hold-fast body of the prefabricated pier of this large-tonnage is applicable to various all-in-one-piece prefabricated pier is spacing, can install use additional on existing upright hoisting appliance.It relies on the rectangular frame main body of rigidity to be sleeved on the lateral wall of prefabricated pier, upwards connect hoist cable by Heave Here, pass downwardly through the hoist cable holding suspension centre and connect cushion cap lifting, the size of rectangular frame main body is corresponding with the largest cross-sectional sized of prefabricated pier to be arranged, to ensure that it can carry easily in hoisting process again and be lifted on any side position height of the prefabricated pier of large-tonnage.Positioning hydraulic cylinder in rectangular frame main body sling in suspender is adjusted prefabricated pier process in can start and use the sidewall of the prefabricated pier of telescopic hydraulic bar horizontal annular pushing tow, hold pier shaft tightly, pier shaft and suspender and rectangular frame main body is made to form an entirety, reduce prefabricated pier shaft rocking in hoisting process, ensure that each suspension centre and accepting of hoist cable are consistent substantially.
The beneficial effects of the utility model are, the lifting hold-fast body reasonable in design of the prefabricated pier of this large-tonnage, Hoisting Security stability are high, it effectively avoids prefabricated pier and hangs the problem producing in the process of supporting body and rock caused each suspension centre discontinuity, has stopped the unsafe factor lifted.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a whole lifting structure in the utility model detailed description of the invention;
Fig. 2 is the application state top view lifting hold-fast body in the utility model detailed description of the invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the lifting hold-fast body of the prefabricated pier of this large-tonnage can be used for the lifting of the all-in-one-piece prefabricated pier 50 of thousands of tons of, and it comprises hanging part 10 together, and this plays hanging part and comprises two suspension hooks be set up in parallel, and is connected with crossbeam 11 between described suspension hook; Two suspension hooks playing hanging part lift a top suspender 20 by hoist cable, and top suspender has a rigid frame, and described suspension hook connects four Heave Heres of this rigid frame by hoist cable.Under the suspender of top, lifting arranges a lifting hold-fast body 30, this lifting hold-fast body comprises the rectangular frame main body 32 that a lifting is arranged, this rectangular frame main ring is horizontally disposed with around the prefabricated pier 50 of vertical lifting, this rectangular frame main body surrounding distribution be fixed with positioning hydraulic cylinder 31, this positioning hydraulic cylinder along this rectangular frame main body to the inside the prefabricated pier 50 of Level Promoting sidewall arrange.In rectangular frame main body, not only distribution is provided with four Heave Heres 33 that hoist cable connects this rectangular frame main body, and also distribution is provided with four of the hoist cable 40 connecting lifting pier cushion cap 60 and holds suspension centre 34.The cylinder body of positioning hydraulic cylinder 31 is fixedly installed in described rectangular frame main body 32, and the telescopic hydraulic bar level of positioning hydraulic cylinder is arranged to pushing tow inside described rectangular frame main body.On the four edges frame of rectangular frame main body, distribution is provided with two positioning hydraulic cylinders separately.As shown in Figure 2, the size of rectangular frame main body 32 is suitable with the cross sectional dimensions of prefabricated pier 50, therefore no matter rectangular frame main body arbitrary height of prefabricated pier can be positioned at, all can realize holding operation tightly to the pier shaft of prefabricated pier, guarantee suspender, hold-fast body are integrally fixedly connected with prefabricated pier.
