Description

Box girder sealing anchor hammer pushing assembly Technical Field The utility model belongs to the technical field of box girder sealing anchors, and particularly relates to a box girder sealing anchor hammer pushing assembly. Background The sealing and anchoring of the railway precast box girder are realized by adopting a manual filling mode, and potential safety hazards such as high labor intensity, low operation efficiency, high-altitude operation and the like exist. The screw conveyer for sealing the anchor is used for conveying concrete for sealing the anchor holes, but the concrete conveyed by the screw conveyer for sealing the anchor can lead the concrete in the anchor holes to be empty after sealing the anchor, and the compactibility is insufficient. Therefore, a box girder sealing anchor hammer pushing assembly with reasonable design is needed at present, and a concrete hammer entering the front end of the hammer pushing piece is pushed into an anchor hole by the hammer pushing piece to gradually realize sealing so as to improve the compactibility of the concrete sealing anchor hole. Disclosure of utility model The technical problem to be solved by the utility model is to provide the box girder sealing anchor hammer pushing assembly which is reasonable in design and gradually realizes the sealing by pushing the concrete hammer entering the front end of the hammer pushing piece into the anchor hole through the hammer pushing piece so as to improve the compactibility of the concrete for sealing the anchor hole. In order to solve the technical problems, the technical scheme is that the box girder sealing anchor hammer pushing assembly is characterized by comprising a bearing shaft, two fan ring pieces symmetrically arranged on the outer side wall of one end of the bearing shaft, two hammer pushing pieces symmetrically arranged between the two fan ring pieces, and a telescopic piece which is arranged on the bearing shaft and can drive the hammer pushing pieces to axially move along the fan ring pieces. The box girder sealing anchor hammer pushing assembly is characterized in that the first annular disc is arranged on the bearing shaft, the fixing part of the telescopic piece is arranged on the first annular disc, and the telescopic part of the telescopic piece penetrates through the first annular disc and is connected with the inner side wall of the hammer pushing piece. The box girder sealing anchor hammer pushing assembly is characterized in that the bearing shaft is provided with the annular disc II, the end part of the hammer pushing piece, which is close to the annular disc II, is provided with an opening, the interior of the hammer pushing piece is hollow, and the telescopic part of the telescopic piece penetrates through the annular disc I and the annular disc II to be connected with the inner side wall of the hammer pushing piece. The box girder sealing anchor hammer pushing assembly is characterized in that a guide cylinder for allowing the telescopic part of the telescopic piece to penetrate is arranged on the first annular disc, the guide cylinder penetrates through the second annular disc to extend into the hammer pushing piece, and the telescopic part of the telescopic piece penetrates through the guide cylinder to extend into the hammer pushing piece and is connected with the inner side wall of the hammer pushing piece. The box girder sealing anchor hammer pushing assembly is characterized in that the thickness of the hammer pushing piece along the axial direction of the bearing shaft is smaller than that of the fan ring piece along the axial direction of the bearing shaft. The box girder sealing anchor hammer pushing assembly is characterized in that the bearing shaft comprises a first section shaft, a second section shaft and a third section shaft which are sequentially connected, the first annular disk is located at the joint of the second section shaft and the third section shaft, the second annular disk is located on the third section shaft, the fan ring piece is fixedly arranged on the outer side wall of the third section shaft, one end of the fan ring piece is fixedly connected with the second annular disk, and a gap is formed between the first annular disk and the second annular disk. Compared with the prior art, the utility model has the following advantages: 1. The utility model provides two fan ring pieces to form two clearance grooves, so that two hammer pushing pieces are arranged in the two clearance grooves, can axially move in the clearance grooves, and are convenient for containing concrete. 2.
