[0141] The present invention provides a box girder anchor sealing construction method, comprising the following steps:

[0142] Step 1: Move the box girder anchoring device to the position through the movable vehicle body 1, and operate the supporting legs 2 to support the ground;

[0143] Step 2: operate the elevating frame 4 to drive the carrying frame 12 and the sealing and anchoring mechanism to descend by lifting the chain 452 until the bottom of the sealing and anchoring mechanism is in contact with the movable vehicle body 1;

[0144] Step 3, filling the loading bin 5 with concrete;

[0145] Step 4: operate the lifting frame 4 to drive the carrying frame 12 and the anchoring mechanism to rise by lifting the chain 452 until the anchoring requirement is met;

[0146] Step 5: When the large anchor hole on the box girder needs to be blocked, the first anchor sealing conveying member 81 is driven to move by the transverse adjustment mechanism and the longitudinal adjustment mechanism until the outlet end face of the first anchor sealing conveying member 81 is aligned with the large anchor hole, and then the upper screw conveyor 6 is operated to make the concrete in the upper bin member 5 enter the first anchor sealing conveying member 81 through the distributor 7, and the first anchor sealing conveying member 81 works to transport the concrete to the large anchor hole for blocking;

[0147] When it is necessary to seal the small anchor holes on the box girder, the second anchor sealing conveying member 82 is driven to move by the lateral adjustment mechanism and the longitudinal adjustment mechanism until the outlet end face of the second anchor sealing conveying member 82 is aligned and fits with the small anchor hole, and then the upper screw conveyor 6 is operated to allow the concrete in the upper bin member 5 to enter the second anchor sealing conveying member 82 through the distributor 7, and the second anchor sealing conveying member 82 works to transport the concrete to the small anchor holes for sealing; wherein, when multiple connected small anchor holes are sealed, the material blocking plate 85 fits with the end face of the box girder or the small anchor hole.

[0148] In this embodiment, step 1 is to operate the supporting leg 2 to support the ground, and the specific process is as follows:

[0149] Remove the pin to release the locking of the telescopic steel tube 44, operate the piston rod of the lower telescopic hydraulic cylinder 25 to extend, drive the inner square steel 24 to extend along the outer square steel sleeve 23, and at the same time, the inner steel tube of the telescopic steel tube 44 extends along the outer sleeve until the distance between the first hydraulic leg 21 and the second hydraulic leg 22 meets the construction requirements, and install the pin to lock the telescopic steel tube 44;

[0150] Then, the piston rod of the outrigger hydraulic cylinder 212 is operated to extend, and the extension of the piston rod of the outrigger hydraulic cylinder 212 drives the outrigger 213 to approach the ground until the outrigger 213 is in close contact with the ground.

[0151] In this embodiment, step 2, the specific process is as follows:

[0152] The lifting hydraulic cylinder 42 in the lifting frame 4 contracts and drives the cross beam 45 to descend in the height direction of the linear slide rail 411 through the upper slider 414 connected to it. At the same time, during the descent of the cross beam 45, when one end of the lifting chain 452 is fixed on the movable body 1, the other end of the lifting chain 452 descends, driving the supporting frame 12 and the anchoring mechanism to descend synchronously with the cross beam 45; wherein, the supporting frame 12 descends along the linear slide rail 411 through the side slider 413.

[0153] In this embodiment, step 4, the specific process is as follows:

[0154] The lifting hydraulic cylinder 42 in the lifting frame 4 is extended by operation, and the lifting hydraulic cylinder 42 extends to push the crossbeam 45 to rise; wherein, the upper slide block 414 connected to the crossbeam 45 rises along the linear slide rail 411;

[0155] During the rising process of the crossbeam 45 , when one end of the lifting chain 452 is fixedly arranged on the movable vehicle body 1 , the other end of the lifting chain 452 drives the supporting frame 12 and the anchor sealing mechanism to rise along the linear slide rail 411 .

[0156] In this embodiment, in step five, the first anchor seal conveying member 81 is driven to move by the transverse adjustment mechanism and the longitudinal adjustment mechanism, or the second anchor seal conveying member 82 is driven to move by the transverse adjustment mechanism and the longitudinal adjustment mechanism. The specific process is as follows:

[0157] The transverse motor 131 drives the transverse gear 133 to rotate through the transverse reducer 132. When the rack 135 is fixedly installed, the transverse gear 133 rotates and moves along the rack 135, and the synchronous transverse slider 136 moves along the transverse slide rail 137. The transverse gear 133 drives the transverse gear member and the transverse slider 136 to drive the first sealing anchor conveying member 81 and the first sealing anchor conveying member 82 to move transversely along the inside of the supporting frame 12 through the upper limit connecting plate 141 until the outlet end face of the first sealing anchor conveying member 81 is aligned with the large anchor hole or the outlet end face of the second sealing anchor conveying member 82 is aligned with the small anchor hole;

[0158] Next, operate the longitudinal hydraulic cylinder 10 to extend, and the longitudinal hydraulic cylinder 10 extends to drive the first anchor sealing conveying member 81 or the second anchor sealing conveying member 82 to move along the longitudinal slide rail 96 through the connecting seat plate 97 through the support block 94, the L-shaped connecting plate 93 and the longitudinal slider 961 until the outlet end face of the first anchor sealing conveying member 81 and the large anchor hole are aligned and fit together, or the outlet end face of the second anchor sealing conveying member 82 and the small anchor hole are aligned and fit together.

[0159] In this embodiment, it should be noted that the movable vehicle body 1 cooperates with the lateral adjustment mechanism and the longitudinal adjustment mechanism to meet the construction needs at different positions.

[0160] In this embodiment, it should be noted that a buffer ring is arranged around the outlet ends of the first sealing and anchoring conveying member 81 and the second sealing and anchoring conveying member 82, and fits with the end surface of the box beam for protection and buffering.

[0161] In this embodiment, when it is implemented, the gravity ball 76 is adjusted to slide along the arc-shaped slide groove 75 through the screw rod 77, thereby driving the feeding plate 71 to swing around the fixed shaft 73 through the baffle plate 72, until the lower end of the feeding plate 71 is close to the feeding bin 84 in the first sealing and anchoring conveying member 81, and the distributor 7 is connected with the first sealing and anchoring conveying member 81;

[0162] Alternatively, the adjusting gravity ball 76 is adjusted to slide in the opposite direction along the arc-shaped slide groove 75 through the screw 77, thereby driving the feeding plate 71 to swing in the opposite direction around the fixed axis 73 through the baffle 72 until the lower end of the feeding plate 71 is close to the feeding bin 84 in the second sealing anchor conveying member 82, thereby connecting the distributor 7 with the second sealing anchor conveying member 82.

[0163] In this embodiment, during the specific implementation, in step 5, the first anchor sealing conveying member 81 works to convey concrete to the large anchor hole for plugging, or the second anchor sealing conveying member 82 works to convey concrete to the small anchor hole for plugging. The specific process is as follows:

[0164] The lower hydraulic motor 111 drives the active sprocket to rotate, and the rotation of the active sprocket drives the driven sprocket 113 to rotate through the transmission chain 112, and the rotation of the driven sprocket 113 drives the screw conveying shaft 83 to rotate, thereby conveying the concrete entering through the feed bin 84 to the port of the conveying cylinder 86 to enter the large anchor hole for sealing or the small anchor hole for sealing.

[0165] In this embodiment, during implementation, the upper hydraulic motor 67 rotates through the transmission shaft 68 to drive the input shaft of the reducer 62 to rotate, and the input shaft of the reducer 62 rotates through the output shaft of the reducer 62 to drive the upper screw shaft 61 to rotate, and the upper screw conveyor 6 will transport the concrete entering the upper screw conveyor 6 through the outlet of the upper bin body 51 to the outlet end of the upper screw conveyor 6, and enter the feed bin 84 through the feed plate 71.

[0166] During the rotation of the upper hydraulic motor 67 , the rotation speed of the upper screw conveyor 6 is detected by the cooperation of the switch sensor and the measuring plate 63 .

[0167] In this embodiment, when anchoring is being performed, when it is necessary to add concrete to the upper bin 5, the hook of the wire rope in the electric hoist 16 hooks the lifting lug 53, and drives the bin 5 to separate from the top of the supporting frame 12; the electric hoist 16 is operated to move along the track 18 to the bottom of the extension frame 17 until the bin 5 is located outside the lifting frame 4; the wire rope in the electric hoist 16 is operated to descend, which drives the bin 5 to descend to the ground, and the upper bin 5 is filled with concrete;

[0168] Next, operate the steel wire rope in the electric hoist 16 to drive the upper bin component 5 to rise, and move along the track 18 to the bottom of the lifting frame 161 until the bottom of the bin component 5 is aligned with the top of the supporting frame 12, then operate the steel wire rope in the electric hoist 16 to drive the upper bin component 5 to descend until the upper bin component 5 is installed on the top of the supporting frame 12.

[0169] To sum up, the present invention is reasonably designed, integrating the anchor sealing mechanism, the adjustment mechanism and the lifting hoist mechanism, and is compact as a whole. It can realize the lifting and lowering, lateral and longitudinal movement of the anchor sealing conveying parts, and can adapt to the sealing of anchor holes at different positions. The two anchor sealing conveying parts can adapt to the sealing of anchor holes of different diameters, thereby improving the anchor sealing efficiency and adaptability. The lifting hoist mechanism can be used to realize the transfer of concrete materials and meet the continuous sealing requirements.
