[0002] With the rapid development of my country's expressway construction, many previously built sections are unable to meet the current demand for greater traffic due to low design standards, oversized sections, and service periods during repairs. In order to meet the needs of economic development, the original cross-line bridges on some roads are demolished and rebuilt. There are two traditional methods for demolishing cross-line bridges. One is blasting demolition, which requires traffic to be interrupted for 36 hours, which has a great impact on the traffic on the old road. The procedures for using explosives are cumbersome, the approval cycle is long, and it is easy to damage the structure of the road below, making the operation dangerous. The other method is mechanical demolition, which requires traffic to be interrupted for 24 hours, which has a great impact on the traffic on the old road, and requires large-scale mechanical equipment for transportation, and the demolition cost is high.

[0021] like Figure 1-3 As shown, the utility model provides a cross-line beam slab rapid dismantling and transporting device, which is used for the dismantling operation of the beam slab 11. The beam slab 11 is arranged on the cap beam 12, and includes a column 1, a stabilizing block 2, a cross beam 3, a longitudinal beam 4, a slide rail 5, a sliding vehicle 6, a lifting beam 7 and a lifting system; the column 1 is arranged on both sides of the beam slab 11; the stabilizing block 2 is arranged on the side of the column 1 and abuts against the cap beam 12, and the stability of the cap beam 12 is ensured during the cutting operation of the beam slab 11; the cross beam 3 is arranged across the beam slab 11 and is arranged at intervals, and its two ends are respectively fixedly connected to the two columns 1; the longitudinal beam 4 is arranged on the cross beam 3 along the length direction of the beam slab 11 The top of both sides; the slide rail 5 is arranged on the top surface of the longitudinal beam 4; the sliding vehicle 6 is arranged on the slide rail 5 and cooperates with the slide rail 5; the lifting beam 7 is arranged across the beam plate 11 and is higher than the cross beam 3, and its two ends are respectively fixed to the two sliding vehicles 6; the lifting system is arranged on the lifting beam 7 and connected to the beam plate 11, and the lifting system includes a lifting motor 8, a lifting pulley 9 and a cable 10; the lifting pulley 9 is symmetrically arranged on the lifting beam 7; the lifting motor 8 is arranged on the lifting beam 7 corresponding to the lifting pulley 9; one end of the cable 10 is connected to the lifting motor 8, and the other end is connected to the beam plate 11 to be removed after bypassing the lifting pulley 9.

[0022] After the cutting of both ends of the beam 11 is completed, the lifting motor 8 lifts the beam 11 through the cable 10, and then starts the sliding vehicle 6 to drive the lifting beam 7 to move, and then transfers the beam 11 to the subsequent transportation tool to complete the dismantling and transportation of the beam 11.

[0023] The columns 1 are steel pipe columns and are arranged at intervals along the length direction of the beam slab 11 .

[0024] The stabilizing block 2 includes a support column and a pad. The inner end of the support column is detachably connected to the column 1. The pad is arranged at the outer end of the support column and abuts against the cap beam 12 to expand the force-bearing area and avoid structural damage.

[0025] The cross beam 3 is arranged across the beam plate 11 .

[0026] The axis of the longitudinal beam 4 intersects with the extended axis of the column 1 .

[0027] Track limiters are arranged at both ends of the slide rail 5 to limit the movement range of the slide vehicle 6 .

[0028] The skid steer 6 is electrically connected to the control system.

[0029] The lifting beam 7 and the lifting system are both provided with two groups corresponding to the two ends of the beam plate 11. The two groups of lifting systems cooperate with each other to complete the removal and transportation of the beam plate 11.

[0030] The cable 10 is a steel wire rope, and a rope clamp is arranged at the end thereof.

[0031] When the beam slab 11 is removed, the following steps are included:

[0032] Step 1: Preliminary preparation;

[0033] 1) Remove the billboards on the guardrails on both sides of beam slab 11;

[0034] 2) Remove the water pipeline on the bridge;

[0035] 3) Clear away dirt and debris from the bridge;

[0036] 4) Prepare standard power and water sources, including 380V 100kw, 63A or above power supply, a 200kW standby generator, and water source (water pressure 4-6bar, water volume 7L / min or above);

[0037] 5) Cutting equipment and staff are in place to ensure that the equipment is in good condition;

[0038] 6) Customized canvas tent: Since the wet joint concrete between the beam and slab 11 is not very dense, a small amount of cooling water will penetrate when cutting. In order to solve the impact of this problem on driving, a canvas tent is used to cover the bottom of the bridge during construction. The top is fixed on the guardrails on both sides and forms a certain slope in the direction of the side ditch, so that the cooling water can flow to the drainage ditch outside the road by itself;

[0039] Step 2: Install the column 1, the stabilizing block 2, the cross beam 3, the longitudinal beam 4, the slide rail 5, the sliding vehicle 6, the lifting beam 7, the lifting motor 8, the lifting pulley 9 and the cable 10 in sequence;

[0040] Step 3: Set up hanging points on the beam slab 11; the hanging points should be arranged at the original designed hanging point positions, and the hanging points can be in the form of wire rope bottom binding, drilling hanging holes, etc.; the hanging point drilling should be done with a reinforced concrete high-speed drilling machine; use drilling equipment to drill hanging holes and correct the wet joint positions. The hanging holes should be located about 0.8 meters away from both ends of the beam slab 11. After drilling a 12CM long and 6.3CM wide hanging hole, tie the wire rope along the hanging hole in advance to shorten the construction time;

[0041] Step 4: The beam and slab 11 all meet the requirements of vibration-free straight-line cutting. The cutting equipment only operates on the bridge deck and no debris such as gravel falls, which does not affect the passage of vehicles under the bridge. When cutting, first cut off the connection and guardrail between the middle pier cap beam 12 and the beam and slab 11 at the abutment to completely separate the two-hole bridge, and then cut along the wet joint in a straight line. The cutting depth is 73 cm (use 80 cm, 120 cm, and 160 cm blades to cut in sequence respectively). The cutting seam should be ensured to be consistent with the wet joint to ensure that the steel bars connecting the wet joint are cut off, so that the hoisting work can proceed smoothly.

[0042] Step 5: Connect the cable 10 to the beam 11; to ensure smooth lifting, lift the beams 11 in sequence and ensure that each beam 11 is not attached to each other; pass the wire rope through the lifting hole, hold the beam 11 to be lifted, and then clamp the wire rope with a rope clamp;

[0043] Step 6: Turn on the lifting motor 8 and pull the wire rope to the position where the bottom of the beam 11 is higher than the cross beam 3, and then lock the rope clamp of the cable 10 to prevent the movable beam 11 from falling off;

[0044] Step 7: Control the skid trolley 6 to move it to the non-dismantling section, then adjust the lifting motor 8 to lower the beam slab 11 into the transport mechanism, and transport the dismantled beam slab 11 out through the transport mechanism;

[0045] Step 8: Repeat steps 3 to 7 until all beams and slabs 11 are dismantled and transported.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
