[0001] The invention belongs to the technical field of bridge construction production equipment, and more specifically, particularly relates to a prefabricated box girder rubber pipe installation device. Background Art

[0002] During the production of box girders, the arrangement of steel strands is an important part of the construction. It is necessary to embed rubber tubes in the box girder mold after the reinforcement is built, and then pull them out after the concrete is initially set to form a prestressed pipeline. The steel strands are passed through the prestressed pipeline and then tensioned to generate elastic retraction force, which in turn transmits pressure to the concrete, improving the overall stability and bearing capacity of the box girder structure.

[0003] However, rubber pull tubes are prone to deformation if they are too long, and inserting them into the box girder reinforcement cage can easily cause positional displacement and inaccurate positioning, making the installation of the rubber pull tubes time-consuming and laborious for construction workers.

[0026] Example:

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

[0028] The present invention provides a prefabricated box girder rubber pipe installation device, comprising a base 1 and a frame 4, wherein the base 1 is movable through a plurality of universal wheels 16 at the bottom, a gantry 2 is arranged on the base 1, and the frame 4 is slidably connected in the gantry 2 and lifted and lowered by a lifting mechanism. 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 in shape, and multiple sliders 6 (two sliders 6 in the figure) are distributed on both sides of the hanger 5. Slide grooves 3 are provided on both inner sides of the gantry 2, and multiple sliders 6 are slidably clamped in the corresponding slide grooves 3. The triangular hanger 5 enables the frame 4 to be stably lifted and lowered in the gantry 2 without affecting the stability of each tool 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. A passage opening 701 corresponding to the positioning tube 8 is horizontally penetrated on the conveying box 7. A plurality of guide wheels 702 distributed on both sides of the passage opening 701 are arranged in the conveying box 7. The guide wheels 702 are driven to rotate by a control mechanism, and the corresponding position of the box girder 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 drawing tube on the box girder reinforcement cage. By extending the positioning tube 8 into the reinforcement cage, a positioning and conveying channel for the rubber drawing tube can be formed. The rubber drawing tube only needs to be fed into the passage opening 701 on the conveying box 7. The rotation of the guide wheel 702 can drive the rubber drawing tube to enter the positioning tube and continuously transport it outward. The installation of the rubber drawing tube in the box girder 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 arranged on the base 1, the shaft of the winding wheel 9 is connected to the first motor 10, a fixed pulley 13 is arranged 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 lifting 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 a shifted center of gravity more flexible.

[0032] Among them, the control mechanism for driving the guide wheel 702 to rotate includes a second motor 11 arranged 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 two adjacent guide wheels 702 located on one side of the passage opening 701 in the conveying box 7 are connected to driven gears 703, and the driving gear 704 is meshed with two adjacent driven gears 703. In this embodiment, two guide wheels 702 are 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 through 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, which ensures the shape of the rubber tube while squeezing both 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 arranged on the frame 4, and the sliding direction is perpendicular to the extending direction of the positioning tube 8. A slide bar 15 is arranged in the frame 4, and a sliding shell 705 is arranged 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, so as to avoid the bending of the end of the rubber pulling tube 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-cover structure, which is convenient for cleaning the inside of the positioning tube 8 and reduces wear on the rubber tube during transportation.

[0036] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
