Description

Technical Field

[0001] The invention relates to the field of construction, and in particular to an adjustable beam-threading lubrication device for prefabricated box beams. Background Art

[0002] Precast concrete box girders are a common method of bridge construction. By pre-casting and then assembling them, bridge construction time can be greatly saved.

[0003] During box girder prefabrication, inner and outer molds are used, with steel cages tied between them before pouring. To ensure strength, several corrugated tubes are placed in the web cages on both sides, and the corrugated tubes are cast together with the webs. After pouring, steel strands are inserted into the corrugated tubes, prestressed, and finally grouting is performed inside the corrugated tubes to seamlessly integrate the corrugated tubes and steel strands. Before pouring the box girder, plastic tubes or other media are inserted to prevent the corrugated tubes and various holes from becoming clogged with concrete slurry. The plastic tubes are then pulled back and forth during pouring. After pouring, the plastic tubes must be removed promptly to prevent them from being welded to the inside.

[0004] In existing technology, plastic pipe insertion and removal are done manually. Due to the large number of holes in the box girder, insufficient manpower is required to perform simultaneous pulling and pulling, which can easily lead to internal welding. Furthermore, the steel strands are inserted one by one, which is inefficient and can easily scratch the inside of the corrugated pipe.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] like Figure 1 、 Figure 2 、 Figure 5 As shown, an adjustable beam lubrication device for prefabricated box beams is provided, the device comprising a base frame 1, a wheel 2 is mounted on the base frame 1, a plurality of beam boxes 3 are stacked and fixedly connected to the top surface of the base frame 1 from bottom to top, the feed side of the beam box 3 is the rear side, and the discharge side is the front side, a plurality of first spline shafts 4 are rotatably mounted between the left and right side walls of the beam box 3, the axis centerline of the first spline shaft 4 is perpendicular to the left and right side walls of the beam box 3, a first opening 5 is provided on the left and right side walls of the beam box 3, the first opening 5 is located above the first spline shaft 4, a first slider 6 is slidably arranged in the first opening 5, a plurality of second spline shafts 7 are rotatably mounted between the two first sliders 6, the axis centerline of the second spline shaft 7 is parallel to the first spline shaft 4;

[0040] A plurality of bundle passing units for passing the steel strands are slidably provided on the first spline shaft 4 and the second spline shaft 7 along the axis direction. A lubrication unit is provided on the front side of the bundle passing unit, and a bundling unit is provided on the rear side.

[0041] In this embodiment, the box girder consists of a bottom plate, a top plate, and two side webs. During the casting of the two side webs, corrugated tubes are inserted inside. During casting, to prevent the corrugated tubes from being blocked by the slurry, plastic tubes need to be inserted and continuously pulled back and forth. After the casting is completed, steel strands need to be inserted into the corrugated tubes for prestressing.

[0042] When it is necessary to insert plastic tubes into the top plate and the webs on both sides, the insertion is done through the bundle insertion unit, which can also pull the plastic tubes back and forth. When it is necessary to insert steel strands into the webs on both sides, the bundling unit can simply bundle several steel strands and insert them together. The lubrication unit can lubricate the steel strands to avoid jamming during insertion.

[0043] During the box girder bundle threading construction, the present invention can insert plastic pipes and steel strands in batches, and bundle the steel strands during the insertion. Multiple steel strands can be inserted at one time to improve efficiency. The steel strands and plastic pipes can also be lubricated to avoid jamming during insertion.

[0044] like Figures 5 to 8 As shown, the bundle-threading unit includes a first box body 8, the top surface of the first box body 8 is open, and second openings 9 are provided on the left and right side walls of the first box body 8. Bearings are installed at the second openings 9, and a plurality of first rubber rollers 10 are rotatably installed between the two bearings. The first spline shaft 4 passes through the second opening 9 and extends into the first box body 8. The first rubber roller 10 is slidably sleeved on the first spline shaft 4. A first spline groove 11 that cooperates with the first spline shaft 4 is provided in the first rubber roller 10. A first annular groove 12 is provided on the circumferential outer wall of the first rubber roller 10, and a plurality of first anti-slip grooves 13 are evenly fixed around the axis in the first annular groove 12;

[0045] The front and rear sides of the top surface of the first box body 8 are fixedly connected with vertical plates 14, and a first slide groove 15 is provided on the opposite side of the two vertical plates 14. The length direction of the first slide groove 15 is perpendicular to the ground. The second box body 16 is slidably located in the first slide groove 15 and is located above the first box body 8. The bottom surface of the second box body 16 is open, and the left and right side walls of the second box body 16 are provided with third openings 17. Bearings are fixed at the third openings 17. A plurality of second rubber rollers 18 are rotatably installed between the two bearings. The second spline shaft 7 passes through the third opening 17 and extends into the second box body 16. The second rubber roller 18 is slidably sleeved on the second spline shaft 7. A second spline groove 19 that cooperates with the second spline shaft 7 is provided in the second rubber roller 18. A second annular groove 20 is provided on the circumferential outer wall of the second rubber roller 18. A plurality of second anti-slip patterns 21 are evenly fixed around the axis in the second annular groove 20;

[0046] A first avoidance groove 22 is provided on the front side wall of the bundle threading box 3, and a second avoidance groove 23 is provided on the rear side wall. A feed pipe 24 is fixedly connected to the rear side wall of the first box body 8, and the feed pipe 24 is communicated with the inside of the first box body 8. The other end of the feed pipe 24 extends out of the second avoidance groove 23, and a winding unit is provided at the end. A discharge pipe 25 is fixedly connected to the front side wall of the first box body 8, and the discharge pipe 25 is communicated with the inside of the first box body 8. The other end of the discharge pipe 25 points to the first avoidance groove 22, and a lubrication unit is provided at the end.

[0047] In this embodiment, the first box body can slide left and right in the beam threading box to adjust the holes at different positions on the top plate and web of the corresponding box beam, and the second box body can slide up and down to drive the second rubber roller closer to or away from the first rubber roller, changing the distance between the two rollers;

[0048] The first spline shaft rotates, driving the first rubber roller to rotate. The second spline shaft rotates, driving the second rubber roller to rotate. The plastic tube or steel strand is inserted from the feed pipe. The annular groove between the first and second rubber rollers clamps the plastic tube or steel strand to be transported, facilitating transport. The tube is then sent out from the discharge pipe, which is aligned with the holes on the top plate and web of the box beam. The winding unit can bundle multiple steel strands, and the lubrication unit can lubricate the steel strand to prevent it from getting stuck during insertion.

[0049] The steel strand does not need to be pulled out after being inserted. When the feeding pipe needs to be pulled out, the first spline shaft and the second spline shaft are reversed, driving the first rubber roller and the second rubber roller to reverse, and the plastic pipe can be pulled out.

[0050] like Figure 6 As shown, the bundling unit includes a first disc 26, which is rotatably sleeved on the circumferential outer wall of the end of the feed pipe 24. The first disc 26 and the feed pipe 24 are coaxial. A first gear ring 27 is fixedly connected to the end surface of the first disc 26 facing the bundle box 3. The first gear ring 27 is coaxial with the first disc 26. A first motor 28 is installed on the circumferential outer wall of the feed pipe 24. A first gear 29 is fixedly connected to the output shaft of the first motor 28. The first gear 29 is meshed with the first gear ring 27.

[0051] A wire roller 31 is fixedly connected to the end surface of the first disc 26 away from the bundle passing box 3 . The wire roller 31 is located at an eccentric position of the first disc 26 , and the axis of the wire roller 31 is parallel to the axis of the first disc 26 .

[0052] In this embodiment, there is usually only one plastic pipe, which does not need to be bundled. There are multiple steel strands. To improve the efficiency of bundling, multiple steel strands are placed in the feed pipe at the same time.

[0053] The worker first pulls out one end of the steel wire from the wire roller and ties it to the steel strand. Then, the first and second rubber rollers are started, and the steel strand is transported forward. The first motor is started, driving the first disc to rotate, which drives the wire roller to rotate around the steel strand. During the transmission process, the steel wire on the wire roller is wrapped around the steel strand, so that multiple steel strands are bundled together for easy transmission. After the transmission is completed, the worker cuts the steel wire short.

[0054] By adjusting the transmission speed of the rubber roller and the rotation speed of the first disc, the amplitude of the steel wire bundling can be changed. It is important to avoid the steel wire being wrapped too tightly to prevent affecting the prestressing of the subsequent steel strands.

[0055] like Figures 2 to 5As shown, the top surface of the top bundle-threading box 3 is fixedly connected to a top oil tank 32, and the bottom surface of the bottom bundle-threading box 3 is fixedly connected to a recovery tank 33. The top oil tank 32 and the recovery tank 33 are connected through an oil pipe 34. A pump body 35 is also installed on the oil pipe 34. The bottom surface of the top oil tank 32 and the top surface of the recovery tank 33 are both provided with leakage holes that are connected to the adjacent bundle-threading boxes 3.

[0056] A second chute 36 is provided on the inner bottom surface of the bundle-threading box 3. The second chute 36 is located below the discharge pipe 25. The sliding direction of the second chute 36 is parallel to the axial center line of the discharge pipe 25. A first water leakage hole 37 is provided on the bottom surface of the second chute 36 to connect to the bundle-threading box 3 below. A first slide 38 is slidingly provided in the second chute 36 to block the first water leakage hole 37. A second water leakage hole 39 cooperating with the first water leakage hole 37 is provided on the first slide 38. A spring 40 is installed in the second chute 36. One end of the spring 40 is fixed to the rear side wall of the second chute 36, and the other end is fixed to the rear side wall of the first slide 38. A guide slope 41 is provided on the front side of the first slide 38.

[0057] In this embodiment, under normal conditions, the lubricating oil drips from the leaking holes in sequence and finally collects in the recovery box at the bottom. When the steel strands need lubrication, the pump body pumps up the lubricating oil and sends it to the top oil tank. The top oil tank cannot store lubricating oil, so the lubricating oil drips from the leaking holes of the top oil tank into the bundle box below.

[0058] The upper and lower adjacent bundle boxes drip lubricating oil through the first leakage hole. In the initial state, the spring is pushed out, the first slide is supported, the second leakage hole is not aligned with the first leakage hole, and the lubricating oil does not continue to drip to the lower layer. Only when the guide slope is pushed, the first slide slides, the spring is compressed, and the second leakage hole is aligned with the first leakage hole, the lubricating oil continues to drip to the lower layer.

[0059] like Figures 7 and 8 As shown, the lubrication unit includes a first frame 42, the first frame 42 is located above the second chute 36, the length direction of the first frame 42 is perpendicular to the bottom surface of the bundle-threading box 3, the first frame 42 is fixedly connected to the front end of the discharge pipe 25, one end of the first frame 42 facing the discharge pipe 25 is communicated with the discharge pipe 25, the end of the first frame 42 facing the first avoidance groove 22 is fixedly connected to a second pipe 43, the other end of the second pipe 43 extends out of the first avoidance groove 22, a notch 44 is provided on the circumferential outer wall of the discharge pipe 25 on the side of the top surface of the bundle-threading box 3, and a third water leakage hole 45 is provided on the circumferential outer wall of the discharge pipe 25 on the side of the bottom surface of the bundle-threading box 3;

[0060] A first square column 46 is provided in the first square frame 42 for sliding up and down. A driving inclined surface 47 cooperating with the guide inclined surface 41 is provided on the rear side wall of the first square column 46. A first channel 48 and a second channel 49 are successively opened between the front and rear side walls of the first square column 46 from bottom to top. The first channel 48 and the second channel 49 are both parallel to the axis of the discharge pipe 25 and can connect the discharge pipe 25 with the second pipe 43. A storage groove 50 is provided on the top surface of the first square column 46. Several rubber caps 51 are stacked in the storage groove 50. The bottom surface of the storage groove 50 is connected with the second channel 49. A lifting block 52 is also fixed on the rear side wall of the first square column 46. The lifting blocks 52 are all slidably mounted on the first cross bar 53. The axis of the first cross bar 53 is perpendicular to the left and right side walls of the bundle threading box 3, and both ends extend from the left and right side walls of the bundle threading box 3.

[0061] In this embodiment, the first square column has two working positions, upper and lower, by raising and lowering the crossbar. When the first square column is in the upper position, the first channel is connected to the discharge pipes and the second pipe at both ends, and the plastic pipe is delivered through the discharge pipes, the first channel, and the second pipe.

[0062] When the first square column is in the lower position, the second channel is connected with the discharge pipes and the second pipeline at both ends, and the steel strand is sent out through the discharge pipe, the second channel, and the second pipeline. At the same time, the driving inclined surface contacts the guiding inclined surface of the first slide plate, pushing the first slide plate open, and the second leakage hole is aligned with the first leakage hole. The lubricating oil drips to the lower layer, drips to the notch of the discharge pipe, drips onto the passing steel strand, and then drips from the third leakage hole of the discharge pipe into the second chute, and drips from the first leakage hole on the second chute to the lower layer.

[0063] Several rubber caps are stored in the storage tank, with the open ends of the rubber caps facing the direction of the discharge pipe. The lowest rubber cap falls into the second channel. When the steel strands are transmitted, a bundle of steel strands enters the second channel and the ends are inserted into the rubber caps. The rubber caps are put on the ends of the steel strands, and the steel strands continue to be transmitted forward against the rubber caps. The rubber caps can prevent the ends of the steel strands from scratching the corrugated pipe during transmission.

[0066] like Figures 3 and 4 As shown, a third motor 57 is installed on the outer side wall of the bundle box 3, and the output shaft of the third motor 57 extends into the bundle box 3 and is fixedly connected to any first spline shaft 4. A belt drive is provided between the other first spline shafts 4;
