Abstract
A bailey beam detachment device comprises a top plate, wherein the top plate is installed on a lifting jack, the lifting jack is installed on a running operation box, a threaded steel rod part penetrates through the top plate, the lifting jack and the running operation box, and a carrying frame is arranged on the threaded steel rod part. The bailey beam detachment device is capable of efficiently and safely detaching bailey beams, and has the advantages of being low in cost, convenient to use and environmentally friendly.
Description
Technical field
The utility model relates to a kind of Bailey beam discharge mechanism, is specifically related to a kind of device that adopts centre-hole jack unloading Bailey beam in bridge cast-in-place section construction process.
Background technology
Bailey truss is more and more widely used in bridge temporary structure, and traditional Bailey beam is removed and adopted sandbox or jacking unloading, uses crane or hoist engine, coordinates pulley system etc., Bailey beam level is hauled out, then the mode of vertically landing is removed one by one.Not only the dismounting cycle long, in unloading process, there are many dangerous matter sources, take the equipment such as crane simultaneously, need a large amount of artificial cooperation, financial cost is increased.Also have a kind of portal-framed structure that adopts to coordinate the unloading of jack screw-thread steel, need to adopt more steel, welding easily causes distortion, makes whole unloading structure stationarity poor.
Summary of the invention
The purpose of this utility model is to provide a kind of Bailey beam easy to operate and with low cost unloading easy device, it can overcome above-mentioned the deficiencies in the prior art, make and easy to use fast, cost is low, unloading wholely only needs 4 these devices and a small amount of artificial cooperation across Cast-in-situ Beam, can be synchronously symmetrical unload whole across Bailey beam support.
The purpose of this utility model is achieved through the following technical solutions: a kind of Bailey beam discharge mechanism, comprise top board, mounting of roof plate is on jack, and jack is arranged on walking control box, screw-thread steel rod member, through top board, jack and walking control box, is also provided with bracket in screw-thread steel rod member lower end.
On screw-thread steel rod member, be provided with multiple screw-thread steel connectors.
Walking control box is a casing of being made by steel plate, and casing upper surface and lower surface and bottom are provided with for the preformed hole through screw-thread steel rod member, and casing front and back end is provided with operation window.
Described jack is Cast-in-situ Beam stretch-draw centre-hole jack.
Walking control box surrounding welding stiffened panel.
The diameter of the preformed hole on walking control box is greater than screw-thread steel rod member, is less than screw-thread steel connector.
The Bailey beam discharge mechanism that the utility model provides, two these devices are established one group of direction across bridge shellfish thunder shoulder pole girder on bracket, and two groups of direction across bridge Bailey beams are whole across Bailey beam support in order to bear.This apparatus structure is simple, easy to operate, utilizes Cast-in-situ Beam stretch-draw centre-hole jack can complete efficiently and safely Bailey beam unloading operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, be described further.
Fig. 1 is the utility model structural representation.
Fig. 2 is that the A-A of Fig. 1 is to view.
Fig. 3 is that the B-B of Fig. 1 is to view.
The specific embodiment
Structure of the present utility model is as Figure 1-3: a kind of Bailey beam discharge mechanism, comprise top board 1, top board 1 is arranged on jack 4, and jack 4 is arranged on walking control box 5, screw-thread steel rod member 2, through top board 1, jack 4 and walking control box 5, is also provided with bracket 6 on screw-thread steel rod member 2.
On screw-thread steel rod member 2, be provided with multiple screw-thread steel connectors 3.Walking control box 5 is a casing of being made by steel plate, and casing upper surface and lower surface and bottom are provided with for the preformed hole through screw-thread steel rod member 2, and casing front and back end is provided with operation window 8.Described jack 4 is Cast-in-situ Beam stretch-draw centre-hole jack.Walking control box 5 surrounding welding stiffened panels.
In the utility model, top board 1 adopts 2 2cm Plate Weldings to form, and steel plate is slightly longer than jack diameter; Jack 4 adopts stretch-draw centre-hole jack; Walking control box 5 also adopts 2cm Plate Welding, form one with jack with wide iron and steel casing, upper and lower and the front and back perforate of casing, control box open up and down two slightly larger in diameter in screw-thread steel rod member 2, be less than the concentric holes of screw-thread steel connector 3, front and back perforate is action pane, be slightly larger than screw-thread steel connector 3 length, be convenient to screw-thread steel connector 3 and pass in and out.Bracket 6, in screw-thread steel rod member 2 lower ends, also adopts 2 2cm Plate Weldings to form, and bracket increases by two stiffened panels, keeps the stability of bracket, prevents from bending.
Use procedure of the present utility model is as follows: prepare before unloading, assembling Lift-on/Lift-off System, first by 7 borings of Cast-in-Situ Segment frange plate, be hole for hoist, cleaning eye waste around, above walking control box 5 is shelved on, screw-thread steel rod member 2 is worn to whole across Bailey beam below by top board 1, jack 4, operation panel 5.
Then assemble direction across bridge shellfish thunder shoulder pole girder (two groups of Bailey bracket beams parallel connection, length is wider than Cast-in-situ Beam width), use two cranes to coordinate the shoulder pole girder of slinging, by bracket 6 connecting thread steel rod elements 2, form Lift-on/Lift-off System.By jack 4, slightly eject and bear whole downward pressure afterwards, remove steel pipe column, make wholely across Bailey beam, can entirety to move down; When centre-hole jack 4 unloads, have all the time a connector stressed, on jack connector stressed after, the connector 3-1 that is arranged in operation window 8 comes loose and rotates up, after oil cylinder stroke completes, the screw-thread steel connector that is arranged in operation window 8 is stressed.Jack 4 rises and rotates up the screw-thread steel connector 3-2 of its top, the screw-thread steel connector 3-2 make screw-thread steel connector 3-2 stressed of stopping the rotation after stroke, and cycling, lands across Bailey beam until whole.
