Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building expansion joint water stop, and particularly relates to a cleaning device for an underground structure expansion joint water stop. BACKGROUND

[0002] The building expansion joint, namely the expansion joint, is a structural joint arranged at a proper position along the construction joint of a building or structure to prevent cracks or damage of the structure due to temperature changes (thermal expansion and cold contraction) of the climate, so as to make the building or structure horizontally expandable in the length direction. The expansion joint divides the building components above the foundation, such as walls, floors and roofs (except wooden roofs), into two independent parts, so that the building or structure can be horizontally expanded in the length direction. In order to prevent water seepage, a water stop belt is generally arranged at the top of the expansion joint. However, the water stop belt needs to be cut, cleaned and replaced when it reaches the designed service life.

[0003] Chinese patent document CN109881612A discloses a special cleaning device for a bridge expansion joint water stop, which is applied in the technical field of bridge expansion joints. The technical solution points of the device are as follows: a bottom plate is provided with two spaced-apart vertical columns, a central shaft is rotatably connected between the two vertical columns, two circular saws are arranged on the central shaft, a through slot is formed in the bottom plate to allow the two circular saws to partially extend out of the through slot, a driving motor is arranged on the bottom plate, and the motor shaft of the driving motor is connected with one end of the central shaft. The device has the advantages of reducing the labor intensity of the operator. The above-mentioned scheme cuts the water stop belt for cleaning and replacement.

[0027] 1. In this invention, when cutting is required, the piston rod of the directional hydraulic cylinder can extend to drive the extrusion plate to move downward. The movement of the extrusion plate can drive the extrusion wheel to extrude the triangular blocks on both sides. The triangular blocks can move away from the force box on both sides and drive the cutting seat to move. The movement of the cutting seat can drive the cutting tool on one side to move. The cutting gap is controlled by the pressing depth of the extrusion wheel driven by the extrusion plate.

In this invention, the connecting rod and abutment rod are designed so that the orientation angle of the connecting rod and the bottom cutting block can be adjusted by turning the limiting bolt. This is beneficial because after the cutting tool cuts the waterstop, when the machine housing is moved, the cutting block can cut the expansion joint sidewall through the inclined surface, which is beneficial for scraping off residual adhesive.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1-9The present invention provides a technical solution: a cleaning device for the expansion joint waterstop of an underground structure, including a housing 1, with movable wheels at the four corners of the bottom of the housing 1, a push rod 9 on the rear side of the housing 1, a dust cover 2 at the bottom of the housing 1, and a cutting distance control mechanism 4 slidably connected to the inner cavity of the dust cover 2, and the cutting distance control mechanism 4 includes two cutting seats 410 that can move in opposite directions, and a cutting blade 8 is mounted on one side of the cutting seat 410 for adjusting the cutting gap of the cutting blades 8 on both sides through the cutting seat 410;

[0043] Furthermore, in this embodiment, the cutting tool 8 is a rotating blade, but a rotating irregular-shaped cutting disc can also be used;

[0044] The top of the dust cover 2 is connected to a dust suction mechanism 6, which is located on one side of the top of the cutting tool 8. The top side of the inner cavity of the dust cover 2 is connected to a guide mechanism 5, which is located behind the moving stroke of the cutting tool 8. The guide mechanism 5 includes a guide plate 501 and a guide box 510. The guide box 510 is connected to the top of the dust cover 2. Both the bottom side of the guide box 510 and the dust cover 2 have openings for the waterstop to enter. The guide plate 501 is used for the waterstop to abut against the side of the guide plate 501 and then enter the guide box 510 upwards.

[0045] The cutting distance control mechanism 4 also includes a support base 401 and a slider 409 connected to the top of the cutting base 410. The support base 401 is adjustablely connected to the dust cover 2. The slider 409 is slidably connected to the slide groove 407 opened at the top of the support base 401. A triangular block 408 is connected to the top of the slider 409. A mounting bracket 402 is connected to the top of the support base 401. A directional hydraulic cylinder 403 is connected to the bottom of the mounting bracket 402. A pressing plate 404 is connected to one end of the piston rod of the directional hydraulic cylinder 403. A pressing wheel 405 is connected to both sides of the bottom of the pressing plate 404. The pressing wheel 405 is used to press the triangular block 408 to drive the cutting base 410 to adjust the distance between the cutting tools 8 on both sides. A sliding hole is opened on one side of the slider 409. A sliding rod 406 is connected between the two sides of the inner cavity of the slide groove 407. The sliding rod 406 is slidably connected in the sliding hole.

[0046] A telescopic control rod 416 is connected between the two cutting blades 8 on both sides, and a third spring 420 is provided on the outer sleeve of the telescopic control rod 416. The two ends of the third spring 420 are respectively connected to the corresponding positions on the outside of the fixed part and the telescopic part of the telescopic control rod 416.

[0047] The specific implementation method is as follows: When cutting is required, the piston rod of the directional hydraulic cylinder 403 can be extended to drive the extrusion plate 404 to move downward. The movement of the extrusion plate 404 can drive the extrusion wheel 405 to extrude the triangular blocks 408 on both sides. The triangular blocks 408 can move away from the sides of the force box and drive the cutting seat 410 to move. The movement of the cutting seat 410 can drive the cutting tool 8 on one side to move. Thus, the cutting gap can be controlled by the pressing depth of the extrusion plate 404 and the extrusion wheel 405. Thus, the cutting tools 8 on both sides with adjustable spacing can adapt to the cutting of expansion joints of different widths. Furthermore, the pressure transmission of the directional hydraulic cylinder 403 can ensure the cutting stability of the cutting tool 8.

[0048] Meanwhile, the sliding of the top slider 409 outside the slide bar 406 can improve the movement stability of the cutting seat 410, which helps to prevent the cutting seat 410 from shaking or shifting, and further improves the processing stability of the cutting tool 8.

[0049] Furthermore, when the gap between the two cutting blades 8 is adjusted, the telescopic control rod 416 can extend or shorten accordingly to ensure the synchronous rotation of the two cutting blades 8. The telescopic control rod 416 can use the external third spring 420 to ensure the radial contact force of the two cutting blades 8, and ensure the autonomous reset of the cutting blades 8 when the extrusion wheel 405 resets, thereby improving the stability of the cutting transmission.

[0050] Please see Figure 9 The inner cavity of the cutting seat 410 is rotatably connected to a shaft via a bearing. One side of the shaft is connected to one side of the cutting tool 8, and the other side of the shaft is connected to a non-circular drive shaft 417. A drive shaft sleeve 418 is fitted over the non-circular drive shaft 417. The drive shaft sleeve 418 slides along the axial direction of the non-circular drive shaft 417. A drive unit 419 is connected to the other side of the drive shaft sleeve 418. The drive unit 419 is connected to one side of the inner cavity of the support seat 401. The cross-sectional shape of the non-circular drive shaft 417 is equal to the shape of the inner cavity of the drive shaft sleeve 418, which is used to transmit the torque of the drive unit 419 when the cutting seat 410 moves.

[0051] The specific implementation method is as follows: Through the design of the irregularly shaped drive shaft 417 and drive shaft sleeve 418, the cross-sectional shape of the inner cavity of the irregularly shaped drive shaft 417 and drive shaft sleeve 418 in this embodiment is hexagonal, which is conducive to ensuring the normal transmission of torque on the drive part 419 side through the fit between the irregularly shaped drive shaft 417 and the drive shaft body, and can achieve the processing stability after the cutting spacing is adjusted by sliding sleeve. The drive part 419 can be set on one side or controlled synchronously on both sides. The drive part 419 can be selected to use a pulley or gear set to cooperate with the motor for cutting drive.

[0052] Please see Figures 6-7A connecting rod 411 is hinged to one side of the cutting seat 410, and an abutment rod 412 is slidably connected to the other side of the connecting rod 411. An adjusting block 413 is provided at one end of the abutment rod 412, and a second spring 414 is sleeved on the abutment rod 412. The two ends of the second spring 414 are respectively connected to the adjusting block 413 and the corresponding position on one side of the connecting rod 411. A cutting block 415 is hinged to the bottom side of the adjusting block 413, and a limiting bolt is provided on one side of both the adjusting block 413 and the cutting seat 410 to limit the orientation angle of the connecting rod 411 and the bottom cutting block 415.

[0053] The specific implementation method is as follows: Through the designed connecting rod 411 and abutting rod 412, the orientation angle of the connecting rod 411 and the bottom cutting block 415 can be adjusted by turning the limiting bolt. This is beneficial because after the cutting tool 8 cuts the waterstop, when the machine housing 1 is moved, the cutting block 415 can cut the expansion joint sidewall through the inclined surface, which is beneficial to scraping off the residual adhesive. The cutting block 415, which is connected to one side of the cutting seat 410 with an adjustable angle, can adapt to the scraping and cutting needs of various expansion joints. Through the designed abutting rod 412, the second spring 414 can use its own elasticity to pull the abutting rod 412 and the bottom cutting block 415 to always be in contact with the expansion joint sidewall, which is beneficial to improving the cutting effect.

[0054] A second connecting block 504 is connected to the rear side of the guide plate 501, and a hinge seat 505 is connected to the top of the second connecting block 504. A second hydraulic cylinder 506 is rotatably connected to the top of the hinge seat 505, and a placement block 507 is connected to the top of the second hydraulic cylinder 506. The placement block 507 is connected to the bottom of the guide box 510. A receiving plate 502 is connected to the side of the bottom opening of the guide box 510 away from the guide plate 501. A fixing rod 503 is connected to the top of the receiving plate 502, and the fixing rod 503 is connected to the groove opened on the bottom side of the guide box 510. An electric roller 508 is rotatably connected between the inner cavities of the guide box 510, and the electric roller 508 is located at the top of the opening of the guide box 510. A receiving box 509 is slidably connected to one side of the guide box 510 for rotating and winding the waste waterstop into the receiving box 509 through the electric roller 508.

[0055] Among them, the electric roller 508 is an electrically driven roller with a brushless motor, which ensures the removal of waste debris from the cut waterstop strip;

[0056] The dust collection mechanism 6 includes a dust collection hood 601, which is connected to an opening at the top of the dust cover 2. A filter bag 603 is connected to the inner cavity of the dust collection hood 601. A chip inlet hood 605 is connected to one side of the filter bag 603 via a connecting pipe 604, and the chip inlet hood 605 is located in front of the cutting tool 8. A dust collection pump 602 is connected to the top of the dust collection hood 601 via a pipe.

[0057] The stabilizing mechanism 3 includes a first connecting block 303 and a guide rod 304. The first connecting block 303 is connected to the outside of the dust cover 2, and a telescopic rod 301 is connected to the top of the first connecting block 303. The top of the telescopic rod 301 is connected to the outside of the housing 1, and a first spring 302 is sleeved on the outer wall of the telescopic rod 301. The two ends of the first spring 302 are fixedly connected to the corresponding positions of the first connecting block 303 and the outside of the telescopic rod 301. The guide rod 304 is connected to the other side of the top of the dust cover 2, and a guide block 305 is slidably connected to the outside of the guide rod 304. The guide block 305 is connected to the inner cavity of the housing 1. A first hydraulic cylinder 7 is connected to the top of the dust cover 2, and the first hydraulic cylinder 7 is connected to the inner cavity of the housing 1.

[0058] The specific implementation method is as follows: Through the designed guide plate 501, the waterstop in the middle can be cut by the cutting blades 8 on both sides and then be rolled up by the rotation of the cutting blades 8 and come into contact with the rear guide plate 501. At this time, the waterstop can be guided into the guide box 510 by the arc surface of the guide plate 501. And by the rotation of the electric roller 508, the waterstop can be rolled into the receiving box 509 on one side inside the guide box 510. This makes it convenient to wind and clean the cut waterstop, avoids residue on the side of the cutting blades 8 from affecting subsequent cutting, and improves the cutting effect.

[0059] Furthermore, after entering the curled waterstop, the waste material of the waterstop can enter the receiving box 509, which facilitates the extraction and cleaning of the waste material. In particular, a corresponding groove should be provided on one side of the casing 1 to facilitate cleaning.

[0060] Furthermore, the designed dust extraction mechanism 6 and dust cover 2 can seal the cutting space, which helps to reduce noise and the transmission of waste to the outside, thus improving the sealing effect. In addition, through the designed stabilizing mechanism 3, the first spring 302 can use its own elasticity to drive the telescopic rod 301 to unfold. The telescopic rod 301 can drive the dust cover 2 to fully contact the ground through the bottom first connecting block 303, which helps to improve the sealing effect.

[0061] Working principle: When cutting is required, the piston rod of the directional hydraulic cylinder 403 extends, causing the extrusion plate 404 to move downward. The movement of the extrusion plate 404 causes the extrusion roller 405 to press the triangular blocks 408 on both sides. The force boxes of the triangular blocks 408 move away from each other and cause the cutting seat 410 to move. The movement of the cutting seat 410 causes the cutting tool 8 on one side to move. The cutting gap is controlled by the pressing depth of the extrusion plate 404 and the extrusion roller 405. The adjustable spacing of the cutting tools 8 on both sides adapts to the cutting of expansion joints of different widths. The pressure transmission of the directional hydraulic cylinder 403 ensures the cutting stability of the cutting tool 8.

[0062] When the gap between the two cutting blades 8 is adjusted, the telescopic control rod 416 extends or shortens accordingly to ensure the synchronous rotation of the two cutting blades 8. The telescopic control rod 416 uses an external third spring 420 to ensure the radial contact force of the two cutting blades 8.

[0063] By adjusting the orientation angle of the connecting rod 411 and the bottom cutting block 415 by turning the limit bolt, it is beneficial that after the cutting tool 8 cuts the waterstop, when the machine housing 1 is moved, the cutting block 415 cuts the expansion joint side wall through the inclined surface and scrapes off the residual adhesive. The cutting block 415, which is connected to the cutting seat 410 with an adjustable angle, can adapt to the scraping and cutting needs of various expansion joints. The second spring 414 uses its own elasticity to pull the abutment rod 412 and the bottom cutting block 415 to always be in contact with the expansion joint side wall.

[0064] When the waterstop in the middle is cut by the cutting blades 8 on both sides, it is curled by the rotation of the cutting blades 8 and comes into contact with the rear guide plate 501. At this time, the waterstop is guided into the guide box 510 by the arc surface of the guide plate 501, and the waterstop is rolled into the receiving box 509 on one side inside the guide box 510 by the rotation of the electric roller 508, so as to facilitate the winding and cleaning of the cut waterstop.
