Description

Technical Field

[0001] The present invention relates to a road and bridge construction method. The mother case of the road and bridge construction method is a road and bridge construction component, system and method with the application number CN202010946853X and the application date September 10, 2020. Background Art

[0002] A bridge generally refers to a structure erected over rivers, lakes and seas to enable vehicles, pedestrians, etc. to pass smoothly. To adapt to the modern high-speed development of the transportation industry, a bridge is also extended to a building that is erected across mountain streams, poor geological conditions or to meet other traffic needs to make passage more convenient. A bridge generally consists of an upper structure, a lower structure, bearings and auxiliary structures. The upper structure, also known as the bridge span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers and foundations; the bearing is a force transmission device provided at the supporting place of the bridge span structure and the pier or abutment; the auxiliary structures refer to approach slabs, conical slopes, revetments, diversion works, etc. The existing bridge construction methods cannot simultaneously meet the requirements of maintaining the under-bridge passage and navigation requirements, ensuring the integrity of the bridge deck, high construction accuracy and fast construction progress. The T-beam is the main component used in bridge erection. In the existing beam yard, the T-beam needs to be placed downward. Generally, a crane is used to load the T-beam onto the beam transporter, which occupies a large area. By turning the T-beam placed upward, the floor area can be saved. However, how to turn the stacked T-beams downward to facilitate the lifting of the T-beams. The T-beam weighs dozens of tons or hundreds of tons and is several meters, more than ten meters or even dozens of meters long. It is made of reinforced concrete structure and should not be distorted or knocked during flipping. The traditional wire hoisting will cause diseases to the T-beam. Summary of the Invention

[0069] The road and bridge construction system of this embodiment includes a beam transport vehicle 4, an approach bridge 5, a bridge pier 6, a prefabricated bridge track 7 and a bridge erecting machine 8.

[0070] The storage device 2 stores the road and bridge T-shaped beams 1. The conveying device 3 is used to convey the road and bridge T-shaped beams 1 onto the beam transport vehicle 4. The beam transport vehicle 4 transports the road and bridge T-shaped beams 1 to the approach bridge 5 at the position of the road and bridge to be laid. Bridge piers 6 are installed at the position of the road and bridge to be laid, and prefabricated bridge tracks 7 are installed on the bridge piers 6. The bridge erecting machine 8 hoists the road and bridge T-shaped beams 1 from the beam transport vehicle 4 on the prefabricated bridge track 7 and erects the bridge.

[0071] The road and bridge construction method of this embodiment includes the following steps.

[0072] Step 1: First, prefabricate the road and bridge T-shaped beams 1 in the beam yard. Then, arrange the storage upward T-shaped beams 11 in an upward manner on the storage prefabricated floor mat 9. Secondly, place the storage downward T-shaped beams 12 in the upward opening gaps between the storage upward T-shaped beams 11. Thirdly, lay a storage intermediate cushion pillow part 13 on the upper surface of the storage downward T-shaped beams 12. After that, lay the storage upward T-shaped beams 11 on the storage intermediate cushion pillow part 13 and stack them layer by layer.

[0073] Among them, for the method of laying the storage intermediate cushion pillow part 13, first, the storage upper top rod 19 drives the storage telescopic cross arm 20 to descend. Under the action of gravity, the storage transverse folding plates 15 are successively placed on the upper surfaces of the corresponding rear storage downward T-shaped beams 12 from bottom to top. Then, the storage transverse hollow cushion pillows 21 are successively conveyed forward by the push rod to realize the laying of the storage intermediate cushion pillow part 13.

[0074] Step 2: For the storage downward T-shaped beams 12, the conveying C-shaped holders 32 clamp the flanks of the storage downward T-shaped beams 12 and hoist them layer by layer from top to bottom onto the beam transport vehicle 4.

[0075] Step three, for the storage upward T-beam 11, first, control the lifting and lowering of the flip front insertion finger 36 to insert into the gap formed by the middle cushion part 13 of the corresponding layer of laying storage and lift the lower surface of the storage upward T-beam 11 upward, and drive the storage upward T-beam 11 forward to form a gap with the adjacent storage upward T-beam 11, until the lower surface of the storage upward T-beam 11 completely enters the flip front insertion finger 36. The flip front insertion finger 36 is placed on the flip torsion spring shaft 39, and the flip swing plate 38 becomes a vertical state under the action of the flip torsion spring shaft 39 to hook the rear side of the storage upward T-beam 11; then, under the action of the flip driven pulling rod 48 and the flip lifting rod 49, the flip L-shaped push plate 51 swings through the middle upright part of the storage upward T-beam 11, and is reset under the action of the flip reset hinge shaft 50 torsion spring; secondly, the flip L-shaped The push plate 51 moves backward to move the middle upright part, and the storage upward T-beam 11 is turned over with the flip rear positioning step 40 as the fulcrum, until it contacts the flip guide roller 42 and the flip buffer support plate 54; again, the flip front tilting arm 52 moves forward to press down the upper side wall of the middle upright part, so that the storage upward T-beam 11 continues to flip and separates from the flip rear positioning step 40; then, the flip reset push rod 56 supports the lower end of the middle upright part of the storage upward T-beam 11, slides along the flip guide rear arc plate 45 and flips into the flip process countersunk 43; then, the flip auxiliary pressing head 53 presses down the upper surface of the storage upward T-beam 11, so that the storage upward T-beam 11 is transformed into the storage downward T-beam 12 to wait for hoisting; then, the storage secondary hollow cushion 24 of the flip station retracts to expose the storage downward T-beam 12 of the lower layer;

[0076] Step four, first, the beam transport vehicle 4 delivers the T-beam 1 of the road bridge to the approach bridge 5 at the location where the road bridge is to be laid; then, the bridge piers 6 are installed at the location where the road bridge is to be laid; secondly, the prefabricated bridge-laying track 7 is installed on the bridge piers 6; thirdly, the bridge-building machine 8 lifts the T-beam 1 of the road bridge from the beam transport vehicle 4 on the prefabricated bridge-laying track 7 and builds the bridge.

[0077] The present invention realizes the storage, transportation and installation of the road-bridge T-shaped beam 1. The present invention realizes the storage and placement of the T-shaped beam through a clever storage device 2, and the transportation device 3 realizes the transportation of the T-shaped beam facing up or down. The storage prefabricated floor mat 9 can be a soft object, so as to have buffering. The storage prefabricated notch 10 is convenient for fingers to insert. The present invention realizes the output of the storage of the T-shaped beam 11 facing up and the storage of the T-shaped beam 12 facing down. The storage of the T-shaped beam 11 facing up can be reversed. The storage intermediate cushion pillow part 13 realizes automatic placement compared with the traditional pillow wood structure. The storage chassis 14 is used as a support. When the storage transverse folding plate 15 and the storage vertical folding plate 16 are used as sleepers, a reverse step structure is formed, thereby reducing the length of the sleepers. This is a major innovation. The protruding length at the top is short, and the lower part is long, which is safe and reliable. The storage process transverse channel 18 is a portal structure, thereby saving the floor area. The storage upper top rod 19 drives the lifting through the storage telescopic cross arm 20. The storage transverse hollow cushion pillow 21 and multiple gradually narrowing storage secondary hollow cushion pillows 24 form a multi-stage telescopic structure. The storage upper process opening 22 ensures that the heights of all levels of pillows are the same. A polytetrafluoroethylene structure can be adopted on it. The storage process vertical groove 23 has good compatibility, thereby avoiding the vertical force on the pull rod. Since the heights of the T-shaped beams are the same, the fixed mode of the first horizontal guide rail 26 for transportation, the second lifting guide rail 27 for transportation, and the third horizontal guide rail 28 for transportation is adopted, thereby reducing the lifting parts installed therefor. The transportation gantry 29 can be two, one in front and one behind. The transportation transverse top frame 30 can be connected to the transportation lifting arm 31 through horizontal or longitudinal drive settings to realize the horizontal or longitudinal transportation of the T-shaped beam. The transportation C-shaped handhold 32 is hydraulically or mechanically controlled to clamp the T-shaped beam for lifting. The hollow opening 33 in the transportation handhold increases the clamping span. The flipping and adjusting frame 34 is supported, and the flipping and lifting base 35 is used to adapt to T-shaped beams at different height levels. The front insertion fingers 36 for flipping are used to insert into the gap. The front insertion process opening 37 for flipping avoids the pillow part. The flipping swing plate 38 and the flipping torsion spring shaft 39 realize one-way swing. The flipping rear positioning step 40 can be moved as a flipping fulcrum. The flipping process step 41 avoids flipping obstacles. The flipping guide roller shaft 42 is used as an intermediate rolling support to reduce the flipping resistance. The flipping process sunk opening 43 is convenient for the T-shaped beam after being reversed. The flipping bearing L-shaped support 44 realizes the front-side support. The flipping guide rear arc plate 45 realizes the flipping guide. The flipping active push rod 46 realizes the driving and pulling. The flipping driven pull rod 48 realizes the driving and pulling of the flipping lifting rod 49. The flipping reset hinge shaft 50 is reset by a torsion spring. The flipping L-shaped push plate 51 realizes one-way swing and one-way drive. The flipping front inclined push arm 52 generates a downward oblique force on the T-shaped beam to continue driving. The flipping auxiliary pressing head 53 realizes the downward pressing of the final direction change. The flipping buffer support plate 54 slowly descends and supports through the flipping buffer spring 55. Of course, after the support, the flipping reset top rod 56 rises to support the lower part of the other side wall of the T-shaped beam to prevent the T-shaped beam from tipping to this side, which is safe and reliable.

[0078] The crane of the present invention performs lateral lifting, with the T-shaped beam perpendicular to the traveling direction. As an equivalent transformation, longitudinal lifting with the T-shaped beam parallel to the traveling direction is also within the scope of protection.

[0079] The present invention is fully described for a clearer disclosure, and prior arts will not be enumerated one by one.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; it is obvious for those skilled in the art to combine multiple technical solutions of the present invention. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
