Description

Technical Field

[0001] The present invention relates to the technical field of bridge pile foundation construction, and in particular to a pile foundation head concrete adsorption device. Background Art

[0002] In the field of highway and railway bridge pile foundation construction, the removal of pile head concrete is a key process that affects the quality and efficiency of the project. During the construction of pile foundation heads, most of the time, manual circumferential cutting and breaking are carried out after the foundation pit is excavated. The construction is intensive and time-consuming, and requires a high level of comprehensive quality of the operators. The noise and dust generated at the circumferential cutting operation site are also not conducive to the physical and mental health of the operators.

[0003] At present, the existing pile head concrete breaking generally adopts the manual ring cutting breaking process, but this method has certain technical defects:

[0004] First, manual circumcision requires cutting point by point after excavation of the foundation pit. The processing of a single pile takes a long time and has low construction efficiency. In addition, the circumcision depth is difficult to accurately control, which makes the pile head prone to bulges or depressions.

[0021] 3. The classification mechanism automatically sorts the crushed materials into different collection chambers (with decreasing sieve hole diameter) according to particle size through the vibrating sieve plate, realizing the refined recovery of concrete aggregate and facilitating the subsequent resource reuse; the top pressure piece uses the power of the negative pressure mechanism to drive the sieve plate to vibrate, without the need for additional energy, which not only improves the screening efficiency but also prevents the sieve holes from being blocked.

[0022] 4. Hydraulic adjustment parts (hydraulic rod + guide frame) accurately control the position of the steel pipe to adapt to different pile foundation heights and horizontal positions, reducing the difficulty of manual adjustment; the self-cleaning system (water pump + water storage tank) can automatically flush the collection box, pipes and screen plates after operation, reducing the workload of manual maintenance.

[0035] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, this embodiment proposes a pile foundation pile head concrete adsorption device, including a vehicle body 1, a collecting box 2 is fixedly connected to the top of the vehicle body 1, one end of the collecting box 2 is provided with a negative pressure mechanism 3, the other end of the collecting box 2 is fixedly connected to a connecting pipe 4 connected to the inlet end of the negative pressure mechanism 3, the inlet end of the connecting pipe 4 is provided with an adsorption pipeline mechanism 5, the adsorption pipeline mechanism 5 includes a support 51 fixedly connected to the top of the vehicle body 1, the top of the support 51 is fixedly connected to a folding tube 52, one end of the folding tube 52 is connected to the connecting pipe 4, the other end of the folding tube 52 is fixedly connected to a steel pipe 54, the bottom end of the steel pipe 54 is provided with a crushing part 55 for crushing the pile foundation, and the top of the steel pipe 5 is provided with an adjusting part 56 for adjusting the position of the steel pipe 54.

[0037] The position of the steel pipe 5 is adjusted by operating the adjustment member 56 so that the steel pipe 5 is aligned with the pile foundation and the crushing member 55 is in contact with the pile foundation. Then, the crushing member 55 is started to crush the pile head of the pile foundation. At the same time, the negative pressure mechanism 3 is started so that the inside of the folding tube 52 is in a negative pressure state, which also generates a negative pressure inside the steel pipe 54. In this way, the crushed pile foundation concrete blocks and dust can be sucked into the steel pipe 54, and then continue to be introduced into the collection box 2 for storage through the folding tube 52 and the connecting tube 4. In this way, the efficiency of breaking the pile foundation can be greatly improved to eliminate the quality defects of the pile head, and at the same time, dust can be prevented from flying and causing air pollution.

[0038] Furthermore, the crushing part 55 includes a steel casing 551 fixedly connected to the outside of the steel pipe 54, and a detachable steel pipe 552 is coaxially arranged on the inner side of the steel casing 551. The top of the detachable steel pipe 552 is fixedly connected to the steel pipe 54 by bolts, and the top of the steel pipe 54 is fixedly connected to a mounting plate 555, and a motor 556 is fixedly installed on the top of the mounting plate 555. The output shaft of the motor 556 is fixedly connected to a rotating shaft 553 that passes through the steel pipe 54, and the bottom end of the rotating shaft 553 is fixedly connected to an auger rod 554. The auger rod 554 passes through the detachable steel pipe 552 and extends to the bottom of the detachable steel pipe 552.

[0039] By starting the motor 556 to drive the rotating shaft 553 to rotate, the spiral drill rod 554 can crush the pile foundation. At the same time, the steel casing 551 can prevent the broken concrete blocks from splashing. At the same time, the negative pressure mechanism 3 is started to make the inside of the folding tube 52 in a negative pressure state, which also makes the inside of the steel tube 54 generate negative pressure. In this way, the broken pile foundation concrete blocks and dust can be sucked into the steel tube 54, and then continue to be introduced into the collection box 2 for storage through the folding tube 52 and the connecting tube 4. In this way, the efficiency of breaking the pile foundation can be greatly improved to eliminate the quality defects of the pile head, and at the same time, dust can be avoided from flying to cause air pollution.

[0040] Furthermore, the adjusting member 56 includes a fixing frame 561 fixedly connected to the top of the vehicle body 1, the top of the fixing frame 561 is fixedly connected to a guide frame 562, one end of the inner side of the guide frame 562 is fixedly connected to a hydraulic rod 1 563, the output end of the hydraulic rod 1 563 is fixedly connected to a movable seat 564, the movable seat 564 is slidingly connected to the inner wall of the guide frame 562, both ends of the bottom of the movable seat 564 are fixedly connected to a hydraulic rod 2 565, and the output ends of the two hydraulic rods 2 565 are fixedly connected to the mounting plate 555.

[0041] By controlling the hydraulic rod 1 563, the movable seat 564 is driven to slide horizontally along the guide frame 562, so that the steel pipe 54 can move in the horizontal direction to adjust the horizontal position of the steel pipe 54. By controlling the hydraulic rod 2 565, the mounting plate 555 can be driven to move in the vertical direction, thereby achieving the vertical height of the steel pipe 54, and then the crushing piece 55 can accurately contact the pile foundation to achieve crushing work.

[0042] Furthermore, the negative pressure mechanism 3 includes a negative pressure chamber 31 opened on the inner side of the collecting box 2, a motor 2 34 is fixedly installed on the inner side of the negative pressure chamber 31, the output shaft of the motor 2 34 is fixedly connected to the suction impeller 33, the outlet end of the negative pressure chamber 31 is fixedly connected to the wind tube 32, the suction impeller 33 is located on the inner side of the wind tube 32, and the inlet end of the negative pressure chamber 31 is fixedly connected to the air inlet filter 35.

[0043] By starting motor 2 34 to drive the suction impeller 33 to rotate, the pressure inside the negative pressure chamber 31 is reduced, so that the inlet end of the negative pressure chamber 31 is in a negative pressure state, and the inside of the folding tube 52 is in a negative pressure state, which also causes negative pressure to be generated inside the steel pipe 54. In this way, the broken pile foundation concrete blocks and dust can be sucked into the steel pipe 54, and then continue to be introduced into the collection box 2 for storage through the folding tube 52 and the connecting pipe 4; the design of the air inlet filter 35 can prevent particulate dust from entering the negative pressure chamber 31 and causing damage to the suction impeller 33.

[0044] Furthermore, a classification mechanism 6 is provided on the inner side of the collecting box 2. The classification mechanism 6 opens three collecting chambers 61 on the inner side of the collecting box 2. The same sieve plate 62 is provided above the three collecting chambers 61. The sieve plate 62 is provided with a first screening area 63, a second screening area 64, and a third screening area 65 corresponding to the three collecting chambers 61. Elastic support members 66 are provided at both ends of the bottom of the sieve plate 62. A top pressure member 67 is provided above the sieve plate 62 for driving the sieve plate 62 to vibrate up and down by cooperating with the start of motor 2 34. The volumes of the three collecting chambers 61 are the same, and the apertures of the sieve holes in the first screening area 63, the second screening area 64, and the third screening area 65 gradually decrease.

[0045] By starting the negative pressure mechanism 3, the inside of the folding tube 52 is in a negative pressure state, which also generates a negative pressure inside the steel tube 54. In this way, the broken pile foundation concrete blocks and dust can be sucked into the steel tube 54, and then continue to be introduced into the collection box 2 through the folding tube 52 and the connecting tube 4. Then the concrete blocks will be scattered on the screen plate 62. Concrete blocks of different volumes are screened in turn through the first screening area 63, the second screening area 64, and the third screening area 65 and fall into different collection chambers 61. In this way, the classified recycling of different concrete aggregates can be realized, and the reuse of resources can be realized.

[0046] Furthermore, the elastic support member 66 includes a support plate 661 fixedly connected to the inner wall of the collecting box 2, and both ends of the support plate 661 are slidably connected with a slide rod 662 that passes through the support plate 661, the top ends of the two slide rods 662 are fixedly connected to the sieve plate 62, and the bottom ends of the two slide rods 662 are fixedly connected to a stop block 664, and the two slide rods 662 are each provided with a spring 663, the top ends of the two springs 663 are in contact with the sieve plate 62, and the bottom ends of the two springs 663 are in contact with the corresponding support plate 661.

[0047] The spring 663 can reduce the impact of concrete aggregate on the sieve plate 62, effectively reducing the damage of the concrete aggregate to the sieve plate 62. At the same time, the spring 663 can provide elastic force for the sieve plate 62, so that the sieve plate 62 vibrates when impacted, thereby improving the screening effect.

[0048] Furthermore, the top pressure member 67 includes a wheel 671 rotatably connected to the inner side of the collecting box 2, and both ends of the wheel 671 are fixedly connected to a knocking rod 672. The knocking rod 672 intermittently contacts the top wall of the sieve plate 62 by cooperating with the rotation of the wheel 671. The side wall of the negative pressure chamber 31 is rotatably connected to a rotating shaft 2 673 that passes through the side wall of the negative pressure chamber 31. One end of the rotating shaft 2 673 is fixedly connected to a bevel gear 1 674, and the output shaft of the motor 2 34 is also fixedly connected to a bevel gear 2 675 that meshes with the bevel gear 1 674. The other end of the rotating shaft 2 673 is fixedly connected to a pulley 1 676, and the wheel 671 is coaxially fixedly connected to a pulley 2 677. The pulley 2 677 and the pulley 1 676 are connected by a belt drive.

[0049] By starting motor 2 34, bevel gear 2 675 can be driven to rotate, so that bevel gear 1 674 drives shaft 2 673 to rotate synchronously, which causes pulley 1 676 to rotate, and pulley 2 677 drives rotating wheel 671 to rotate synchronously, so that knocking rod 672 rotates circumferentially and intermittently conflicts with the top wall of sieve plate 62. When knocking rod 672 conflicts with the top wall of sieve plate 62, sieve plate 62 is squeezed and moves downward. At this time, spring 663 is squeezed to accumulate potential energy. When knocking rod 672 is separated from sieve plate 62, spring 663 releases potential energy and causes sieve plate 62 to vibrate violently. This not only improves the screening effect of sieve plate 62, but also avoids clogging of the sieve holes of sieve plate 62.

[0050] Furthermore, a water storage tank 8 is opened at one end of the bottom of the collecting box 2, and a cleaning mechanism 7 is provided on the outside of the water storage tank 8. The cleaning mechanism 7 includes a water pump 71 fixedly installed on the outside of the cleaning mechanism 7, the inlet end of the water pump 71 is fixedly connected to the water inlet pipe 72, the inlet end of the water inlet pipe 72 is connected to the inside of the water storage tank 8, the outlet end of the water pump 71 is fixedly connected to the water outlet pipe 73, the outlet end of the water outlet pipe 73 is connected to the connecting pipe 4, one end of the folding tube 52 is fixedly connected to valve 1 53, and one end of the water outlet pipe 73 is fixedly connected to valve 2 74.

[0051] When the pile foundation adsorption is completed, open valve 2 74 and close valve 1 53, then start the water pump 71 so that the water inlet pipe 72 draws out the water inside the water tank 8, and then introduces the water into the collection box 2 through the outlet pipe 73 to clean the sieve plate 62; after opening valve 1 53, the folding tube 52 and the steel pipe 54 can be cleaned, so that the equipment can be self-cleaned to reduce the labor of manual cleaning.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
