Description
Technical field
The present invention relates to Large Precast Members hoisting technology field, belong to the devices and methods therefor that a kind of use suspension rod of falling T-shaped carries out large scale prefabricated lifting especially.
Background technology
At present, along with the development of water transport engineering project technology, concrete lifting component technology is increasingly mature, but the overwhelming majority adopts suspension ring and " suspension rod of falling T-shaped " to carry out concrete lifting component as suspender in the middle of harbour, Wharf Construction, when adopting " suspension rod of falling T-shaped " to lift, because its hole for hoist is reserved comparatively dark, easily cause land peace suspender, pluck the phenomenons such as suspender difficulty, work efficiency are low under water.
Summary of the invention
The object of the present invention is to provide a kind of novel Large Precast Members hanging apparatus and method, to reach simple and quick, to reduce costs, increase substantially the object of work efficiency.
Large Precast Members hanging apparatus provided by the present invention, there is the bar of falling T-shaped and auxiliary device, it is characterized in that, described auxiliary device comprises fixed block and securing arrangement, securing arrangement be welded on pin-and-hole on the bar of falling T-shaped and with it with the use of pin, fixed block is provided with jack, and fixed block is positioned on the upside of the T prefix of the bar of falling T-shaped, arranges rotary handle above the bar of falling T-shaped.
Large Precast Members hanging method provided by the present invention, is characterized in that, comprise the steps:
1) the land installation of suspender
Step 1-1, the suspension rod of falling T-shaped and auxiliary device winch to above component by operating personal simultaneously, and it is synchronously moved to component and reserves directly over hole for hoist by workmen;
Step 1-2, makes fixed block and T prefix on same level axis, and the large hook of crane ship slowly drops to above component and carries out coarse positioning;
Step 1-3, crane ship continues to weigh hook in the hand, and fixed block and T-shaped bar at maintenance fixed block and T prefix, are put into component and reserved hole for hoist, and pinned in jack pin being inserted fixed block under the state of same level axis by workmen;
Step 1-4, after fixed block arrives position of rotation, stop declining, pull out on pin, workman, by T-shaped bar 90-degree rotation, makes the axes normal of T prefix and fixed block, and pin is stayed in pin-and-hole, and workman withdraws scene, and crane ship ship starts lifting;
2) component is installed and suspender excision under water
Step 2-1, crane ship is by Large Precast Members handling under water, and prefabricated components are arranged on design attitude by Divers under the guidance of technology people;
Step 2-2, after Components installation completes, crane ship is weighed hook in the hand and is relaxed one's efforts to steel rope, and Divers puts in place;
Step 2-3, Divers will the bar of falling T-shaped rotate to fixed block same level axis, insert pin, and withdraw to safety zone;
Step 2-4, because fixed block can keep the suspension rod of falling T-shaped to reserve vertical center in hole for hoist at component, suspender can successfully be left the water by crane ship;
Step 2-5, enters the lifting flow process of next component.
Present invention effectively prevents the generation of the phenomenons such as the hole clipping that existing Large Precast Members hoisting process is installed, excision T-shaped bar easily occurs, effectively shorten the bottom time of Divers, reduce the probability of occurrence of submarine sickness, ensured its personal safety; This method has easy and simple to handle, safe and reliable, that work efficiency is high good effect.
Accompanying drawing explanation
Accompanying drawing part discloses specific embodiments of the invention, wherein
Fig. 1, fixed block birds-eye view of the present invention;
Fig. 2, the structural representation of hanging apparatus of the present invention;
Fig. 3, hanging apparatus of the present invention enters concrete test block view;
Fig. 4, view after T-shaped bar 90-degree rotation of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, Large Precast Members hanging apparatus provided by the present invention, there is the bar of falling T-shaped 5 and auxiliary device, wherein, described auxiliary device comprises fixed block 2 and securing arrangement, securing arrangement be welded on pin-and-hole 3 on the bar of falling T-shaped and with it with the use of pin 4, fixed block is provided with jack 6, fixed block is positioned on the upside of the T prefix 1 of the bar of falling T-shaped, arranges rotary handle 7 above the bar of falling T-shaped.
First Large Precast Members hanging method provided by the present invention is the land installation of suspender, and the suspension rod of falling T-shaped and auxiliary device winch to above component by operating personal simultaneously, and it is synchronously moved to component and reserves directly over hole for hoist by workmen; Make fixed block and T prefix on same level axis, the large hook of crane ship slowly drops to above component and carries out coarse positioning.
As shown in Figure 3, after hanging apparatus carries out coarse positioning above component 8, crane ship continues to weigh hook in the hand, workmen is keeping fixed block and T prefix under the state of same level axis, fixed block and T-shaped bar are put into component and reserves hole for hoist 9, and pinned in jack pin being inserted fixed block, fixed block and reserved hole for hoist close contact in this process, serve the effect of location simultaneously, avoid the hole clipping phenomenon that the displacement of T-shaped bar causes.
As shown in Figure 4, after fixed block arrives position of rotation, stop declining, pull out on pin, workman, by T-shaped bar 90-degree rotation, makes the axes normal of T prefix and fixed block, and pin is stayed in pin-and-hole, and workman withdraws scene, and crane ship ship starts lifting.
Crane ship is by after Large Precast Members handling extremely under water, and prefabricated components are arranged on design attitude by Divers under the guidance of technology people; After Components installation completes, crane ship is weighed hook in the hand and is relaxed one's efforts to steel rope, and now the bar of falling T-shaped rotates to parallel with fixed block by Divers, inserts pin, and withdraws to safety zone; Because fixed block can keep the suspension rod of falling T-shaped vertical center in hole for hoist, suspender can successfully be left the water by crane ship.
Hanging apparatus of the present invention, coordinates the reserved hole for hoist in Large Precast Members to use, simply efficiently, safe and reliable.
