[0001] The utility model belongs to the technical field of bridge construction production equipment, and more specifically, relates to a rubber tube installation device for prefabricated box beams. Background Art

[0002] During box girder production, the placement of steel strands is a crucial step. Rubber pull-out tubes are embedded in the box girder mold after the reinforcement is laid. After pouring and initial setting of the concrete, they are pulled out to form a prestressed conduit. The steel strands are threaded through the prestressed conduit and then tensioned, generating an elastic retractive force that transfers pressure to the concrete, improving the overall stability and bearing capacity of the box girder structure.

[0003] However, if the rubber pull tube is too long, it will be easily deformed. Inserting the rubber pull tube into the box girder reinforcement cage will easily cause position deviation and inaccurate positioning. The installation of the rubber pull tube is time-consuming and labor-intensive for construction workers.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a prefabricated box girder rubber tube installation device is provided to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To the attached Figure 4 As shown:

[0028] The utility model provides a prefabricated box girder rubber tube installation device, comprising a base 1 and a frame 4, the base 1 is movable through a plurality of universal wheels 16 at the bottom, a gantry 2 is provided on the base 1, the frame 4 is slidably connected in the gantry 2 and is lifted and lowered by a lifting mechanism, such as Figure 1 and Figure 2As shown, a hanger 5 is provided on one side of the frame 4, and the side of the hanger 5 is triangular. A plurality of sliders 6 are distributed on both sides of the hanger 5 (two sliders 6 are shown in the figure). Slide grooves 3 are provided on both inner sides of the gantry 2. The plurality of sliders 6 are slidably clamped in the corresponding slide grooves 3. The triangular hanger 5 enables the frame 4 to be stably raised and lowered in the gantry 2 without affecting the stability of the various tools on the frame 4.

[0029] The frame 4 is respectively provided with a conveying box 7 and a positioning tube 8 extending from the frame 4. The conveying box 7 is horizontally penetrated with a channel opening 701 corresponding to the positioning tube 8. A plurality of guide wheels 702 distributed on both sides of the channel opening 701 are provided in the conveying box 7. The guide wheels 702 are driven to rotate by a control mechanism, and the corresponding position of the box beam moved by the base 1 is moved. The frame 4 is lifted and lowered so that the conveying box 7 can be positioned to the corresponding entrance position of the pre-buried rubber pulling tube on the box beam reinforcement cage. By extending the positioning tube 8 into the reinforcement cage, a positioning and conveying channel for the rubber pulling tube can be formed. The rubber pulling tube only needs to be fed into the channel opening 701 on the conveying box 7. The rotation of the guide wheel 702 can drive the rubber pulling tube into the positioning tube and continuously convey it outward. The installation of the rubber pulling tube in the box beam reinforcement is more convenient, the positioning is more accurate, and labor is saved.

[0030] Among them, the lifting mechanism includes a winding wheel 9, a first motor 10 is provided on the base 1, the shaft of the winding wheel 9 is connected to the first motor 10, a fixed pulley 13 is provided on the top of the gantry 2, and a cable 12 is connected to the winding wheel 9. The other end of the cable 12 passes through the fixed pulley 13 and is connected to the hanger 5 on the frame 4. The first motor 10 drives the winding wheel 9 to retract and release the cable 12, so as to control the raising and lowering position of the frame 4 in the gantry 2.

[0031] The slider 6 is cylindrical and rollingly clamped in the slide groove 3, which reduces the friction between the slider 6 and the slide groove 3, making the lifting of the frame 4 with an offset center of gravity more flexible.

[0032] Among them, the control mechanism that drives the guide wheel 702 to rotate includes a second motor 11 provided on the conveying box 7, and the output shaft of the second motor 11 vertically passes through the conveying box 7 and is connected to the driving gear 704 at the bottom of the conveying box 7. The bottoms of the two adjacent guide wheels 702 located on one side of the passage opening 701 in the conveying box 7 are connected to the driven gear 703, and the driving gear 704 is engaged with the two adjacent driven gears 703. In this embodiment, there are two guide wheels 702 distributed on the left and right sides of the passage opening 701 in the conveying box 7, and the second motor 11 drives the two guide wheels 702 on one side to rotate in the same direction. When the rubber pulling tube extends into the passage 701 of the conveying box 7 and contacts the guide wheel 702, the guide wheel 702 can drive the rubber pulling tube to move forward by friction, extend outward into the positioning tube 8, and then transport it to the box girder reinforcement cage.

[0033] In this embodiment, the circumference of the guide wheel 702 is concave in an arc shape, and evenly distributed vertical grooves are opened on the circumference of the guide wheel 702, which increases the adaptability of the guide wheel 702 and the rubber tube. At the same time, an elliptical gap is formed between the two corresponding guide wheels 702, ensuring the shape of the rubber tube while squeezing the two sides of the rubber tube for forward transportation more sensitively.

[0034] In another embodiment, if Figure 3 and Figure 4 As shown, the conveying box 7 is slidably set on the frame 4, and the sliding direction is perpendicular to the extension direction of the positioning tube 8. A slide bar 15 is provided in the frame 4, and a sliding shell 705 is provided at the bottom of the conveying box 7. The sliding shell 705 is slidably clamped on the slide bar 15. A hydraulic rod 14 is installed at the bottom of the conveying box 7, and the hydraulic rod 14 is installed in the sliding shell 705. The output end of the hydraulic rod 14 is connected to the frame 4. In addition to providing sliding support, the setting of the sliding shell 705 can also protect the driven gear 703 and the driving gear 704 to prevent external interference, and the extension and retraction of the hydraulic rod 14 can control the conveying box 7 to move left and right on the frame 4. The fine position adjustment can enable the rubber pulling tube to smoothly enter the positioning tube 8 after extending out of the channel opening 701, thereby avoiding the bending of the rubber pulling tube end that has just extended out of the channel opening 701 and touching the outside of the positioning tube 8, causing damage and deformation.

[0035] In addition, the positioning tube 8 may include a lower half tube and an upper half tube, which are hinged to form a flip-top structure, which is convenient for cleaning the inside of the positioning tube 8 and reduces wear on the rubber tube during transportation.

Many modifications and variations will be apparent to those skilled in the art.
