Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a bridge demolition crushing device with noise reduction function. Background Technology

[0002] In construction engineering, bridge demolition is an important step. It can not only reduce the probability of safety hazards caused by aging and damage of bridges and protect people's lives and property, but also meet the needs of citizens' travel by demolishing or renovating existing bridges in order to meet the needs of new urban functions or adjust spatial layout, as people's requirements for living environment and quality of life continue to increase.

[0003] Existing bridge demolition methods commonly include mechanical cutting, blasting, and manual demolition. When demolishing large bridges, blasting is often used to improve efficiency. By strictly controlling the amount of explosives and the direction of blasting, large bridges can be demolished quickly. However, during blasting, the detonation of a large amount of explosives generates a lot of noise and vibration, which not only disturbs residents in the surrounding area but may also cause damage to surrounding buildings and facilities due to splatter. When there is an error in the amount of explosives, excessive explosives may also cause ground subsidence or geological disasters. Therefore, it is necessary to design a bridge demolition crushing device with noise reduction function. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a bridge demolition crushing device with noise reduction function, including support columns 3, two support columns 3 with fixed cross blocks 12 fixedly connected to their inner sides, a drilling rig 9 fixedly connected through the bottom of the fixed cross blocks 12, a support frame 11 fixedly connected to the top of the fixed cross blocks 12, an extension column 14 fixedly connected to the top of the support frame 11, a hydraulic splitting rod 1 fixedly connected to the top of the extension column 14, connecting columns 17 fixedly connected to both sides of the fixed cross blocks 12, and an arc angle adjusting block 19 fixedly connected to the side of the connecting column 17 away from the fixed cross blocks 12. A hydraulic press 15 is fixedly inserted into the top of the support column 3. A connecting ring 18 is fixedly connected to the bottom of the hydraulic press 15. The inner side of the connecting ring 18 is slidably connected to the outer surface of the connecting column 17. A composite slide groove 23 and a rotating chamber 22 are opened inside the support column 3. The rotating chamber 22 and the composite slide groove 23 are interconnected. The surfaces of the connecting column 17, the connecting ring 18 and the arc angle adjusting block 19 are all slidably connected to the inner wall of the composite slide groove 23. A rotating mechanism for adjusting the angle is provided on the side of the arc angle adjusting block 19 away from the fixed cross block 12. The bridge demolition operation is realized by the cooperation of the drilling machine 9 and the hydraulic splitting rod 1.

[0022] Furthermore, the rotating mechanism includes a rotating cylinder 6 and a cross-shaped fixing block 16. The rotating shaft end of the rotating cylinder 6 is fixedly connected to one side of the cross-shaped fixing block 16. An electric push rod 4 is fixedly connected to one side of the support column 3. A connecting block 5 is fixedly connected to the telescopic end of the electric push rod 4. The bottom of the connecting block 5 is fixedly connected to the surface of the rotating cylinder 6 away from the cross-shaped fixing block 16. An insertion hole is provided on both the side of the arc angle adjusting block 19 away from the connecting column 17 and the side of the support column 3. The side of the cross-shaped fixing block 16 is slidably connected to the inner wall of the insertion hole, which allows the position of the drilling rig 9 and the hydraulic splitting rod 1 to be interchanged.

[0023] Furthermore, a limiting slider 7 is fixedly connected to the bottom of the rotary cylinder 6, and a support ring plate 20 is fixedly connected to one side of the limiting slider 7. The side of the support ring plate 20 is movably inserted through the support column 3 on the side away from the fixed horizontal block 12. The outer side of the arc angle adjusting block 19 is rotatably connected to the inner side of the support ring plate 20, so that when the rotary cylinder 6 is rotating, the arc angle adjusting block 19 can exert pressure on the rotating shaft end of the rotary cylinder 6.

[0024] Furthermore, auxiliary clamping plates 21 are fixedly connected to both sides of the support ring plate 20. The side of the auxiliary clamping plate 21 is inserted through and movable into the side of the support column 3 away from the fixed horizontal block 12, which further improves the support effect of the support ring plate 20.

[0025] Furthermore, a pressing base plate 13 is fixedly connected to the bottom of the inner side of the two supporting columns 3. The top of the pressing base plate 13 has a through hole to increase the parallel tension of the ground when the drilling machine 9 is operating, thereby reducing the splashing of stones.

[0026] Furthermore, counterweight blocks 10 are fixedly connected to both sides of the bottom end of the support column 3 to improve the stability of the device when it is placed and prevent it from tipping over due to the vibration generated during drilling.

[0027] Furthermore, a lifting ring 2 is fixedly connected to the top of the supporting column 3 to facilitate the hoisting and moving of the device.

[0028] Furthermore, reinforcing plates 24 are fixedly connected to both sides of the pressing base plate 13 to further increase the stability of the device when the drilling machine 9 drills downwards.

[0029] Working principle: First, the hook of the external hoisting equipment is hooked to the lifting ring 2. Then, the hoisting equipment moves the device to the location where it needs to be broken. Then, the bottom of the supporting column 3 and the pressing base plate 13 are stably attached to the bottom of the bridge under the action of the counterweight blocks 10 on both sides. To further improve the stability of the device during operation, the reinforcing plate 24 can also be fixed by external anchor bolts, and the bridge can also be tied with ropes, with both ends of the ropes fixed to the reinforcing plate 24. Then, by starting the hydraulic press 15 and the drilling rig 9, the hydraulic press 15 drives the drilling rig 9 downward to drill holes in the bridge surface through the connecting ring 18 and the connecting column 17. After the pre-embedded holes are drilled, the hydraulic press 15 drives the drilling rig 9 to reset. The arc angle adjusting block 19 moves upward with the connecting column 17, thus moving into the rotating chamber 22, which is a circular design. Then, the electric push rod 4 is started, which drives the rotary cylinder 6 to move inward, thereby driving the cross fixing block 16 to insert into the insertion hole on one side of the arc angle adjusting block 19 for fixing. At this time, the arc angles on both sides of the bottom end of the arc angle adjusting block 19 are in contact with the inner side of the support ring plate 20, providing support for the subsequent rotation of the arc angle adjusting block 19. After the cross fixing block 16 is inserted, the rotary cylinder 6 is started, and the two rotary cylinders 6 are... The cross-shaped fixing block 16 drives the arc angle adjusting block 19 to rotate 180 degrees, so that the hydraulic splitting rod 1, under the action of the extension column 14, the support frame 11 and the fixed cross block 12, flips over so that the hydraulic splitting rod 1 faces downward. When the hydraulic splitting rod 1 is adjusted, the electric push rod 4 is activated. The electric push rod 4 drives the rotating cylinder 6, the support ring plate 20 and the auxiliary clamping plate 21 away from the arc angle adjusting block 19 and the support column 3 through the connecting block 5. Then, under the action of the hydraulic press 15, the hydraulic splitting rod 1 is inserted into the drilled pre-embedded hole. As the hydraulic pressure continues to increase, the piston rod on one side of the hydraulic splitting rod 1 gradually applies pressure to the inner wall of the pre-embedded hole, destroying its internal structural stress, and thus a large crack is generated in this section of the bridge. Then, with the help of external breakers or stone picks, the large pieces of concrete can be peeled off.
