Description

Technical Field

[0001] The invention belongs to the technical field of anchor sealing equipment, and in particular relates to an anchor sealing equipment and method for the end face of a high-speed railway box girder. Background Art

[0002] After the grouting operation is completed, the high-speed railway prefabricated box beam needs to complete the anchoring work on both ends of the beam as soon as possible. The anchoring operation can protect the prestressed tendons of the beam from being corroded by external air, moisture and other substances, ensure the stability of the anchoring area, and enhance the integrity and waterproofness of the structure.

[0003] Taking the prefabricated box beam of the double-ramp high-speed railway as an example, the traditional operation mode is: workers place a large amount of mixed concrete boxes on the two fork arms at the front of the forklift, and the workers stand in the concrete box and rise to the specified height with the box to seal the anchor hole at the top of the beam. The workers pour concrete into the anchor hole one shovel at a time and compact it with a vibrator. This anchor sealing method has a hard disadvantage that the anchor hole cannot be completely filled with concrete. After the anchor sealing end plate is removed, the part that cannot be filled needs to be filled.

[0004] It can be seen that the disadvantages of the traditional operation mode are:

[0005] 1. Workers are in danger of working at heights without any protective measures;

[0006] 2. The anchor hole cannot be completely filled and surface repairs are required later.

[0007] The above description of the background technology is only for facilitating a deeper understanding of the technical solution of the present invention, and should not be regarded as admitting or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0020] S2. The distances between the distance meter and the beam end face are measured by two symmetrical distance meters on the rotating gear plate.

[0038] The sealing anchor assembly 3 includes a rotating support plate 31, which is mounted on the rotating gear plate 26. The rotating support plate 31 is provided with an inner frame 32, an outer frame 33, a second guide rail 39 and a third guide rail 310. The inner frame 32 is slidably mounted on the second guide rail 39, and the outer frame 33 is slidably mounted on the third guide rail 310.

[0040] Program calibration: The program of the equipment is written according to the designated anchor hole position before it leaves the factory. All data are set based on the calibrated anchor hole, and the data is accurate. Operation calibration: When the equipment is put into actual production operation, the actual relative position of the equipment and the beam body cannot completely coincide with the theoretical position, and needs to be set on site by the operator.

[0041] The anchor sealing method of the above-mentioned anchor sealing device comprises:

[0042] S1. Install the end plate assembly on the anchor hole 4 at the end face of the beam so that the feed hole 12 partially overlaps with the anchor hole 4, and rotate the feed guide plate 13 so that the outlet of the feed guide plate 13 is connected with the overlapping part; at this time, the end plate assembly is in an open state;

[0043] S2. The equipment moves to the calibration position of the beam to be operated through the mobile trolley 21; the calibration program is started, the equipment is operated, and the distance between the distance meter 38 and the beam end face is measured by the two symmetrical distance meters 38 on the rotating gear plate 26. The control system calculates the difference between the two distances. If the difference between the two distances is outside the specified range, the rotating gear plate 26 is driven to rotate and adjust the angle between the anchor seal component 3 and the beam end face until the difference between the two distances is within the specified range. At this time, the front of the anchor seal component 3 is parallel to the beam end face; at this time, the distance data of the distance meter 38 is the vertical distance between the anchor seal component 3 and the beam end face, and the system records the difference between the current vertical distance and the data before factory calibration. So that the automatic program can automatically compensate.

[0044] After the front face of the anchor seal assembly 3 is parallel to the beam end face, the X and Y coordinate positions of the anchor seal assembly 3 are adjusted through the interface of the control system to ensure that the discharge pipe 34 can smoothly pour concrete into the anchor hole 4 of the calibration procedure; this position is the initial position after the calibration is completed;

[0045] S3. The equipment operates in the anchor hole operation sequence set by the program. The anchor sealing assembly 3 reaches the first anchor sealing point. The internal gear drive group 313 drives the inner frame 32 to move into place. The discharge pipe 34 and the vibrating rod 35 on the inner frame 32 reach the filling point to pour concrete and compact. When the concrete overflows from the feed guide plate 13, the inner frame 32 retracts and the height is adjusted by the lifting platform 25. The external gear drive group 314 drives the outer frame 33 to extend, the fork 37 clamps the rotating handle 15, and the hydraulic motor drive group 36 works to rotate the feed guide plate 13 180°. At this time, the end plate assembly is in a closed state. The anchor sealing operation of the current anchor hole is completed, and the equipment runs to the next anchor hole for operation.
