The concrete working principle and the beneficial effects of the embodiment are as follows:

the working principle is as follows:

and (3) anchoring and disassembling: before the concrete placement on the next section road surface, at first install hydraulic jack on last supporting seat 21, make hydraulic jack one end and last supporting seat 21 butt, the constructor rotates the latch segment that compresses tightly with lower supporting seat 22 with the help of controlling the pole, after the latch segment moves one section distance along vertical direction upward, with the help of hydraulic jack, make hydraulic jack's hydraulic stem along vertical direction downstream, the string basket also is vertical downstream under hydraulic jack's effect, string basket hangers overlap joint is on the track that slides, the string basket breaks away from with the bridge floor.

Operating personnel can begin to dismantle anchor structure, constructor unscrews the latch segment of lower extreme under the bridge floor with the help of devices such as steel foot rest, dismantle clamping piece 3 from the jib down, operating personnel continues to rotate the latch segment that compresses tightly with under bracing seat 22 with the help of holding the pole, then upwards lift the jib along vertical direction, make the jib lower extreme be higher than the bridge floor, then make latch segment butt elastic rubber piece compress tightly under bracing seat 22 with the help of holding the rotatory latch segment of pole, constructor can rotate the actuating handle this moment, under bracing seat 22 is along the vertical upward movement of lead screw 51 length direction, pulley 72 and bridge floor contact, under bracing seat 22 is unsettled with ground, constructor with whole upper latch member 81 and jib transfer to next anchor point can.

And (3) anchoring and mounting: the constructor firstly rotates the locking block tightly attached to the surface of the lower support seat 22 by the holding rod, slowly lowers the suspender downwards, the movable plate 71 is slowly pushed during the lowering of the hanger rod so that the hanger rod is aligned with the anchoring through hole penetrating through the bridge deck, the hanger rod penetrates through the hanging basket after penetrating through the bridge deck, the constructor can slide the disassembled lower clamping piece 3 on the hanger rod again, the lower clamping piece 3 is pressed and fixed by the locking block, the second fastening piece 33 passes through the second flange 32 to enable the lower clamping piece 3 to be locked and fixed with the hanging basket, the locking block is rotated by the holding rod, the locking block is tightly abutted against the surface of the lower support seat 22, a constructor rotates the screw rod 51 by the driving handle, the lower support seat 22 moves towards one end close to the bridge floor along the vertical direction, the lower support seat 22 is abutted against the bridge floor, the pulley 72 is suspended, and at the moment, a constructor fixes the lower support seat 22 and the bridge floor by penetrating the first rib 222 through the first fastener 223; then install hydraulic jack on lower support seat 22, support seat 21 makes support seat 21 and jack butt through the position control of adjusting the latch segment, then support tight latch segment with lower support seat 22 with the help of holding the pole rotation, adjust the latch segment towards one side of keeping away from the bridge floor, hydraulic jack upwards jacks up along vertical direction and hangs the basket, it breaks away from with the track that slides to hang the basket hangers, it laminates with the bridge floor to hang the basket, then rotatory latch segment makes latch segment and lower support seat 22 surface support tight, treat that the basket installation is stable after, take off hydraulic jack, constructor can carry out the concrete placement on next section road surface.

Has the advantages that:

through rotating driving piece 6, driving piece 6 drives the lead screw 51 rotation of being connected with it, realize the synchronous rotation of many lead screws 51 under the meshing connection effect of chain 53 and gear 52, and then realize the motion of lower carriage 22 along lead screw 51 length direction, when lower carriage 22 contacts with the bridge floor, moving member 7 is unsettled with the bridge floor, and then make the steady placing on the bridge floor of whole upper clamping piece 2, threaded connection between jib and the latch segment realizes that upper clamping piece 2 and lower clamping piece 3 are fixed to the locking between string basket and the bridge, when moving member 7 contacts with the bridge floor, lower clamping piece is empty with the bridge floor suspension, constructor just can shift whole upper clamping piece 2 and jib to next anchor point and anchor the installation, and easy operation is convenient and fast, the cost has been saved to a certain extent.

Because the elastic piece 83 plays a role in protecting the locking block, the upper support seat 21, the lower support seat 22 and the lower clamping piece 3, the abrasion between the locking block and the upper support seat 21, between the locking block and the lower support seat 22 and between the locking block and the lower clamping piece 3 is reduced, and the service life is prolonged.

Through installing chain 53 and gear 52 in cavity 42, cavity 42 plays a effect of accomodating to chain 53 and gear 52, has reduced outside cement mortar and has entered into to spatter and spill on gear 52 and chain 53, and then has guaranteed that lower support seat 22 is along ascending normal clear with the decline of lead screw 51 length direction.

Because when carrying out anchor installation and dismantlement, need not all demolish whole anchor system completely, only need dismantle lower clamping piece 3 from the jib, compare in dismantling whole anchor system, simplified constructor's operating procedure for anchor structure's installation and dismantlement are convenient and simple swift more.

Because the lower support seat 22 is to bear the weight of the upper support seat 21 and the suspension rod, the threaded connection between the threaded sleeve 23 and the screw rod 51 increases the contact area between the lower support seat 22 and the screw rod 51, thereby enhancing the connection stability between the lower support seat 22 and the screw rod 51.

Because the lower support seat 22 is rotatably connected with the plurality of screw rods 51, compared with the situation that the lower support seat 22 moves along the length direction of the screw rods 51 only by using one screw rod 51 and a plurality of guide rods, the plurality of screw rods 51 increase the stress points between the lower support seat 22 and the screw rods 51, so that the stable movement of the lower support seat 22 along the length direction of the screw rods 51 is realized by the uniform stress on the surface of the lower support seat 22 in the process that the lower support seat 22 moves along the length direction of the screw rods 51.

Due to the fact that the holding rod is arranged, a constructor can rotate the locking block to adjust the relative position between the locking block and the hanging rod by means of the holding rod, time and labor are saved, and operation is simple.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
