Description

Technical Field

[0001] The invention relates to the technical field of pile foundation removal, and in particular to a bridge pile foundation removal device based on water cutting technology. Background Art

[0002] In the process of urban road planning, old bridges or viaducts need to be demolished and rebuilt. Conventional demolition methods include manual demolition, hydraulic shearing demolition, drilling and crushing, vibration demolition or blasting demolition. Manual demolition and hydraulic shearing demolition are suitable for pile foundations with smaller diameters. For pile foundations with larger diameters, drilling and crushing or blasting demolition will be selected. However, these two methods produce large noises. The drilling and crushing method takes a long time to construct and produces long-term noise. The blasting demolition will produce huge impact and is highly dangerous. If the pile foundation is located around residential areas, the above two methods will be subject to various obstacles in implementation.

[0003] Water jet cutting technology is widely used in construction, manufacturing, mining, environmental protection and other fields. It has been applied to the removal of pile foundations because of its extremely low noise, high safety and strong cutting ability. For example, a bridge pile foundation removal device disclosed in the announcement number: CN118148131A; the patent adopts a cutting device that can rotate along the circumference of the supporting structure and a hammering device that hammers the cut concrete to achieve the effect of continuous cutting and crushing of the pile foundation; although the cutting of the pile foundation can be achieved, the following technical problems still exist in actual use: 1. The pile foundation cut by the cutting device will present a complete concrete ring. When it is crushed by the hammering device, it cannot present a good crushing effect because it is an integral setting, which will cause the detached concrete ring to be unable to completely detach from the adhesion of the pile foundation, and there will be a large concrete convexity. 1. The cutting device can only perform circular cutting on circular pile foundations. When facing special-shaped or square pile foundations, it cannot adapt to the cutting depth, which greatly limits its use environment. 2. Although the two symmetrical nozzles can adjust the cutting angle according to needs, the two nozzles can only be adjusted in the opposite direction. After the two nozzles are adjusted through two sets of angle adjustment structures, the cutting stroke will be greatly reduced, which seriously affects the subsequent cutting progress. The circular cutting work that originally took several times to achieve now requires multiple times to achieve the cutting of the concrete ring. Summary of the invention

[0004] In view of the above problems, a bridge pile foundation demolition equipment based on water cutting technology is provided. By proposing a device that can not only efficiently cut different pile foundations but also make the cut concrete ring easy to remove, the technical problems that when the existing demolition equipment cuts off the pile foundation, the concrete ring formed is difficult to clean and the cutting efficiency of the cutting device when changing the cutting state is low.

[0032] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0033] See also Figures 1 to 8As shown: a bridge pile foundation removal equipment based on water cutting technology, including a first longitudinal reciprocating drive module 1 and a second longitudinal reciprocating drive module 2 and an equidistant cutting module 3 and a multi-directional cutting module 4 respectively fixedly arranged at the driving ends of the first longitudinal reciprocating drive module 1 and the second longitudinal reciprocating drive module 2; the equidistant cutting module 3 and the multi-directional cutting module 4 are arranged adjacent to each other; the multi-directional cutting module 4 includes two groups of first nozzles 41 and second nozzles 42 that can move longitudinally and crosswise and a control module 43 for respectively controlling the actions of the first nozzles 41 and the second nozzles 42; a stroke monitoring module 5 is also arranged in the middle of the equidistant cutting module 3 for real-time monitoring of the distance between the cutting end of the equidistant cutting module 3 and the foundation pile.

[0034] The connecting ends of the first longitudinal reciprocating drive module 1 and the second longitudinal reciprocating drive module 2 are respectively fixedly connected to the driving ends of the external circumferential rotating device, and the circumferential rotating device is a device for synchronously driving the first longitudinal reciprocating drive module 1 and the second longitudinal reciprocating drive module 2 to rotate circumferentially along the axis of the pile to be cut, thereby achieving the purpose of circular cutting of the pile; this is the prior art and will not be described in detail here;

[0035] The cutting ends of the equidistant cutting module 3 and the multi-directional cutting module 4 are arranged flush with each other at the same height;

[0036] When it is necessary to perform circular cutting on the pile foundation, firstly, an external power supply is connected to drive the stroke monitoring module 5 to operate to detect the distance between the equidistant cutting module 3 and the pile foundation, and then the equidistant cutting module 3 adjusts its cutting distance according to the monitoring data. After the equidistant cutting module 3 is adjusted, the equidistant cutting module 3 is operated again to adjust the cutting thickness; when the equidistant cutting module 3 is adjusting the cutting distance and cutting thickness, the multi-directional cutting module 4 is adjusted synchronously to make its extended length and cutting thickness consistent with the adjusted cutting distance and cutting thickness between the first nozzle 41 and the second nozzle 42; finally, the equidistant cutting module 3 and the multi-directional cutting module 4 are connected to the water source respectively to put them into the cutting state, while prompting the circumferential rotating device to operate, thereby achieving the circular cutting effect on the pile foundation until the pile foundation is completely removed.

[0037] See also Figure 4 As shown: the equidistant cutting module 3 includes a third nozzle 31 and a fourth nozzle 32 that can radially approach or move away from the pile; the third nozzle 31 and the fourth nozzle 32 are driven and controlled by a first linear driver 33 and a second linear driver 34 arranged at the driving end respectively; the second linear driver 34 and the first linear driver 33 have the same structure.

[0038] The first linear drive 33 is composed of a first extension rod 331, a second extension rod 332, a third extension rod 333, and a first electric push rod 334 coaxially fixedly disposed in the first extension rod 331, the second extension rod 332, and the third extension rod 333. When the third nozzle 31 needs to be driven to extend radially, it is only necessary to connect an external power supply to drive the output shaft of the first electric push rod 334 to extend.

[0039] When the third nozzle 31 needs to be adjusted according to the monitoring interval of the stroke monitoring module 5, firstly, an external power supply is connected to drive the first electric push rod 334 to move. The output shaft of the first electric push rod 334 extends to drive the first extension rod 331 to extend radially until it extends to the required stroke and stops, thereby achieving the effect of driving the third nozzle 31 to be radially adjusted.

[0040] See also Figure 3 and Figure 4 As shown: the first longitudinal reciprocating drive module 1 includes a first drive part 11 and a second drive part 12 which can move towards or away from each other; the first drive part 11 and the second drive part 12 are driven and controlled by a first drive unit 13 connected to their drive ends respectively.

[0041] The first driving part 11 is fixedly disposed at the end of the first linear driver 33, and the second driving part 12 is fixedly disposed at the end of the second linear driver 34;

[0042] The first driving unit 13 is composed of a bidirectional screw rod 131, a mounting seat 132 for mounting the bidirectional screw rod 131, and a servo motor 133 fixedly arranged at the end of the mounting seat 132; further, the first driving unit 13 for driving the first driving part 11 and the second driving part 12 to approach each other can also be other forms, so as to achieve the purpose of driving the first driving part 11 and the second driving part 12 to approach each other or to move away from each other;

[0043] When it is necessary to drive the first driving part 11 and the second driving part 12 to move closer to or away from each other, so as to adjust the distance between the third nozzle 31 and the fourth nozzle 32, the servo motor 133 is first driven to drive the bidirectional screw rod 131 to rotate. The bidirectional screw rod 131 synchronously drives the first driving part 11 and the second driving part 12 on the two threaded ends to rotate while rotating, so as to achieve the purpose of driving the first driving part 11 and the second driving part 12 to move closer to or away from each other; thereby achieving the effect of adjusting the distance between the third nozzle 31 and the fourth nozzle 32.

[0044] See also Figure 8As shown: the multi-directional cutting module 4 also includes a sliding frame 44 capable of guiding the longitudinal sliding of the first nozzle 41 and the second nozzle 42, and a first guide frame 45 and a second guide frame 46 respectively vertically arranged at the rear sides of the first nozzle 41 and the second nozzle 42; the first guide frame 45 and the second guide frame 46 are slidably matched with the control end of the control module 43.

[0045] The first guide frame 45 and the second guide frame 46 are both composed of a rectangular plate and a first slide groove extending through the rectangular plate;

[0046] The two ends of the sliding frame 44 are respectively fixedly connected to the driving ends of the first linear drive 33 and the second linear drive 34 through the fourth extension rod 441; thus, when the driving ends of the first linear drive 33 and the second linear drive 34 extend to drive the third nozzle 31 and the fourth nozzle 32 to radially approach the pile, the first nozzle 41 and the second nozzle 42 can be synchronously driven to move under the action of sliding, thereby ensuring that the multiple groups of nozzles are set in the same state in the ready state;

[0047] The first nozzle 41 and the second nozzle 42 are staggered in the left and right directions and are respectively slidably matched with the sliding frame 44 through the first sliding grooves provided on the sides; thereby, the first nozzle 41 and the second nozzle 42 are relatively embedded in the left and right sides of the sliding frame 44, and since the first nozzle 41 and the second nozzle 42 are relatively embedded in the left and right sides of the sliding frame 44; when the first nozzle 41 or the second nozzle 42 slides longitudinally along the sliding frame 44 under the drive of the control module 43, the two do not interfere with each other and are staggered with each other; thereby achieving the purpose of automatically adjusting the cutting trajectory according to the cutting requirements, and at the same time will not reduce the maximum cutting stroke, thereby ensuring the processing efficiency;

[0048] The first guide frame 45 and the second guide frame 46, which are respectively vertically arranged on the rear sides of the first nozzle 41 and the second nozzle 42, are used to slide with the control end of the control module 43, so as to ensure that when the control module 43 synchronously controls the first nozzle 41 and the second nozzle 42 to slide longitudinally along the sliding frame 44, the connection end can slide to the limit point according to the control stroke.

[0049] See also Figure 4 , Figure 6 and Figure 7As shown: the control module 43 includes a first control rod 431 and a second control rod 432, the middle parts of the first control rod 431 and the second control rod 432 are hinged by a hinge column 433, and the front ends of the first control rod 431 and the second control rod 432 are also fixedly provided with a sliding shaft 434 that slides with the first guide frame 45 and the second guide frame 46 respectively; the rear ends of the first control rod 431 and the second control rod 432 are also hingedly provided with a second electric push rod 435 and a third electric push rod 436 that can respectively longitudinally propel the first control rod 431 and the second control rod 432 to move; the non-working ends of the second electric push rod 435 and the third electric push rod 436 are fixedly connected to the second longitudinal reciprocating drive module 2.

[0050] The sliding shaft 434 disposed at the front end of the first control rod 431 and the second control rod 432 respectively slides with the second sliding groove 47 provided on the first guide frame 45 and the second guide frame 46 vertically disposed at the rear side of the first nozzle 41 and the second nozzle 42;

[0051] Since the middle parts of the first control rod 431 and the second control rod 432 are hingedly connected in an X shape through the hinge column 433 and the front ends of the first control rod 431 and the second control rod 432 are slidably matched with the first guide frame 45 and the second guide frame 46 respectively through the sliding shaft 434; when the rear ends of the first control rod 431 and the second control rod 432 are driven by the second electric push rod 435 and the third electric push rod 436 respectively, the front ends of the first control rod 431 and the second control rod 432 will move synchronously, thereby achieving the purpose of driving the third nozzle 31 and the fourth nozzle 32 to move closer or farther away from each other; thereby presenting different cutting trajectories.

[0052] See also Figure 6 As shown: the second longitudinal reciprocating drive module 2 includes a third drive unit 21 and a fourth drive unit 22 capable of longitudinal staggered sliding; the third drive unit 21 and the fourth drive unit 22 are driven and controlled by a second drive unit 23 and a third drive unit 24 fixedly connected to their drive ends respectively.

[0053] The second drive unit 23 and the third drive unit 24 are substantially similar in structure to the first drive unit 13, except that the drive screws in the second drive unit 23 and the third drive unit 24 are both one-way screws;

[0054] The second electric push rod 435 and the third electric push rod 436 are both used as extension rods, and move synchronously with the second driving unit 23 and the third driving unit 24, so as to ensure that the first control rod 431 and the second control rod 432 in the folded state can move synchronously with the third nozzle 31 and the fourth nozzle 32, so as to send the first control rod 431 and the second control rod 432 in the folded state to the designated workstation;

[0055] When the first nozzle 41 needs to be driven to slide longitudinally along the sliding frame 44 , it is only necessary to drive the second electric push rod 435 corresponding to the first nozzle 41 to slide longitudinally to achieve the purpose of driving the first nozzle 41 to slide longitudinally along the sliding frame 44 in linkage.

[0056] See also Figure 4 As shown, the travel monitoring module 5 includes a detection element 51 capable of real-time detection of the pile distance and an adjustment element 52 for dynamically adjusting the center of the detection element 51; the detection element 51 is horizontally arranged toward the foundation pile.

[0057] The detection element 51 is always arranged in a horizontal state toward the foundation pile under the action of the adjustment element 52; when it is necessary to detect the distance between the equidistant cutting module 3 and the foundation pile, it is only necessary to connect an external power supply to drive the detection element 51 to work, and the detection element 51 transmits the detected data to the control system, and the control system adjusts the distance between the equidistant cutting module 3 and the foundation pile in real time according to the detection data, so that when cutting the special-shaped foundation pile, the distance between the equidistant cutting module 3 and the foundation pile can be flexibly controlled according to the detection results, thereby realizing effective cutting of the special-shaped foundation pile.

[0058] See also Figure 4 As shown: the detection element 51 is a laser rangefinder.

[0059] By using a laser rangefinder as the detection element 51, it is possible to achieve real-time distance measurement of piles of different shapes to be cut, and to flexibly control the distance between the equidistant cutting module 3 and the piles; thereby achieving the effect of effectively cutting piles of different shapes through the equidistant cutting module 3.

[0060] See also Figure 4 As shown: the detection element 51 is a travel displacement sensor.

[0061] In order to ensure that the detection element 51 can present a good detection effect in different weather and different working conditions, and will not lose the detection accuracy due to external factors, a stroke displacement sensor is used as the detection element 51, which can achieve direct contact with the side wall of the pile foundation, thereby achieving a mechanical contact detection effect; further, in order to ensure that there is no risk of wear or bending damage to the stroke displacement sensor during continuous contact with the side wall of the pile foundation, it is preferred to use an elastically retractable telescopic rod to replace the direct contact between the detection end of the stroke detector and the side wall of the pile foundation, and the contact end of the telescopic rod is also embedded with a ball, so as to minimize contact wear; the stroke displacement sensor detects the telescopic stroke of the telescopic rod to achieve stroke detection, thereby achieving a ranging effect.

[0062] See also Figure 3 and Figure 4As shown: the adjustment element 52 is composed of two groups of scissor rod groups 521 hinged end to end; the middle of the two groups of scissor rod groups 521 is also horizontally spanned with a fixed rod 522, and the fixed rod 522 is hinged to the hinge points of the two groups of scissor rod groups 521. The scissor rod group 521 is composed of two groups of first connecting rods and second connecting rods hinged in the middle in a scissor shape, and the two free ends of the first connecting rod and the second connecting rod are respectively hinged to the hinge parts vertically arranged on the lower surface of the adjacent first linear drive 33 and the upper surface of the second linear drive 34; because the fixed rod 522 is horizontally spanned in the middle of the two groups of scissor rod groups 521 and is respectively hinged to the hinge points of the two groups of scissor rod groups 521; in the adjustment state, no matter how the first linear drive 33 and the second linear drive 34 move, the fixed rod 522 is always horizontally centered between the first linear drive 33 and the second linear drive 34.

[0063] The present invention can not only efficiently cut pile foundations of different shapes, but also make the cut concrete ring easy to clean, and has high cutting efficiency and good effect.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
