Description

Technical Field

[0001] This invention relates to the field of dredging equipment technology, specifically to a grouting pipe dredging device. Background Technology

[0002] During the use of grouting technology, grouting pipe blockage often occurs. However, the existing dredging equipment is extremely cumbersome to dredge, requires too much auxiliary equipment, occupies too much space, and is costly. At the same time, the long dredging time will cause the cement inside the pipe to harden, increasing the difficulty of dredging and seriously affecting the construction progress. Blocked grouting pipes cannot be dredged, which will lead to a lot of material waste and increase project costs. Based on this situation, there is an urgent need for a simple, efficient and fast grouting pipe dredging device. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0004] This invention relates to a grouting pipe unblocking device, comprising a frame, a telescopic component installed inside the frame, a seat inside the frame, the end of the telescopic component being connected to the seat, the seat having a cavity, and an outlet at the bottom of the seat, through which wastewater generated during the cleaning process is discharged.

[0005] The base has two opposing bayonets. One bayonet contains a sleeve, which has a fixing component that engages with the bayonet. A spring is fitted onto the sleeve and located on the outside of the base. The other bayonet contains a sleeve, which has a fixing component that engages with the bayonet. Both sleeves are fitted onto a screw. An impeller is installed at one end of the screw. A gear is installed inside the base and fitted onto the screw. A cover is installed on the bayonet of the base. One side of the gear passes through a slot in the cover and is connected to the drive assembly for transmission.

[0006] Furthermore, the frame includes uprights and top rods. The top ends of two parallel uprights are connected by the top rods to form an inverted U-shaped structure. The inner side of the uprights is provided with a groove, and the bottom surface of the groove has a sliding groove.

[0007] Furthermore, pins and feet are provided on opposite sides of the seat. The feet are located on the upper side of the pins. The pins move along the slide groove. The feet are located in the groove. The telescopic component is a hydraulic telescopic column. The hydraulic telescopic column is installed at the top of the groove. The telescopic end of the hydraulic telescopic column is connected to the feet.

[0008] A wedge-shaped block is installed at the bottom of the column to increase the contact area at the bottom of the column, thereby improving the stability of the frame during placement. A hydraulic telescopic column is installed at the top of the groove. The telescopic end of the hydraulic telescopic column is connected to the foot. By contracting the telescopic end of the hydraulic telescopic column, the foot moves upward along the groove. By extending the hydraulic telescopic column, the foot moves downward along the groove, thereby realizing the free adjustment of the height of the seat. In addition, a pin is provided on the outside of the seat, which moves along the slide. By contacting the inner wall of the slide, the pin improves the overall limiting effect of the seat and prevents the seat from swinging during the rising or falling process.

[0009] Furthermore, the sleeve body two has a brush body inside, a 70 frame body on the outside of the sleeve body two, and a limiting groove one on the fixing member corresponding to the sleeve body two. The force of the spring two is outward along the axis of the sleeve body two, and the 70 frame body cooperates with the corresponding limiting groove one.

[0010] Furthermore, the sleeve body one has a protrusion inside, the protrusion moves along the thread on the outer surface of the screw, the sleeve body one has a protrusion one, and the fixing member corresponding to the sleeve body one has a limiting groove two. The force of the spring one is outward along the sleeve body one, and at the same time, the protrusion one cooperates with the corresponding limiting groove two.

[0011] Furthermore, the outer side of the screw is provided with a limiting groove distributed along the axis, and a bushing is installed in the middle circular hole of the gear. The bushing is composed of two semi-circular bushings spliced ​​together. The inner wall of the bushing is provided with a protruding ridge that cooperates with the limiting groove. The gear drives the screw to rotate synchronously through the bushing.

[0012] Because the gear is fitted with a bushing that limits the screw, the gear drives the screw to rotate synchronously. Under the action of the spring, the sleeve body 1 engages with the corresponding limiting groove of the fixing part 2. Thus, the rotating screw will not drive the sleeve body 1 to rotate under the action of friction. At the same time, the protrusion provided in the sleeve body 1 moves along the spiral groove of the screw, so that the screw moves to the outside. The impeller installed at the end of the screw extends into the grouting pipe, which facilitates the cleaning of the grouting pipe.

[0013] Furthermore, several T-slots are distributed in a ring on the end face of the gear near the sleeve body one. A slider and a spring three are installed in the T-slots. The ends of bolts passing through the spring three and the slider are installed in the screw holes opened on the bottom surface of the T-slots. The spring three pushes the slider to fit tightly against the bottom surface of the T-slots. A connecting rod is rotatably connected to the slider. Several connecting rods are connected to the same gear ring. Several hinge seats are evenly distributed on the outer surface of the gear ring. The ends of the connecting rods are installed on the corresponding hinge seats through pins.

[0014] When the impeller reaches a hard deposit during its insertion into the grouting pipe, it cannot continue to extend. During rotation, the screw pushes the sleeve to compress the spring, causing the protrusion to disengage from the limiting groove. Simultaneously, the teeth of the ring mesh with the gear ring, enabling the gear to drive the sleeve to rotate synchronously, preventing the screw from continuing to extend and damaging the impeller. Under the action of the spring, the impeller adheres tightly to the deposit for slow cleaning. In addition, when subjected to a large reverse force, the slider installed at the end of the connecting rod moves outward to compress the spring, thereby causing the sleeve to continue to retract within the seat for further buffering.

[0015] Furthermore, the sleeve body has a ring body at one end near the gear, and the ring body has teeth distributed in a ring at one end near the gear. The teeth of the toothed ring face the ring body, and the ring body moves toward the toothed ring to achieve mutual meshing between the ring body and the toothed ring.

[0016] The present invention has the following beneficial effects:

[0017] This invention features a bushing installed inside the gear that engages with the screw's limiting position, enabling the gear to drive the screw to rotate synchronously. Under the action of a spring, the sleeve body 1's protrusion engages with the corresponding fixing part's limiting groove 2. Thus, the rotating screw, under friction, will not cause the sleeve body 1 to rotate. Simultaneously, the protrusion inside the sleeve body 1 moves along the screw's spiral groove, allowing the screw to extend outwards. The impeller installed at the screw end extends into the grouting pipe, facilitating cleaning of the grouting pipe. The structure is simple and easy to operate.

[0018] In this invention, when the impeller is cleaning a grouting pipe, if the inside of the grouting pipe is blocked and the impeller, which rotates with the screw, cannot cut the blockage, the rotating screw cannot continue to penetrate. During rotation, the screw, unable to move along its axis, increases the reverse force on the protrusion and sleeve, causing the sleeve to move towards the gear and compress the spring until the protrusion disengages from the limiting groove. This allows the spiral groove to drive the protrusion and sleeve to rotate synchronously, preventing the threaded rod from continuing to extend and damaging the impeller.

[0019] This invention features a wedge-shaped block at the bottom of the column to increase the contact area and thus improve the stability of the frame during placement. A hydraulic telescopic column is installed at the top of the groove, with its telescopic end connected to the foot. By retracting the telescopic end of the hydraulic telescopic column, the foot moves upward along the groove; by extending the hydraulic telescopic column, the foot moves downward along the groove, thus allowing for free adjustment of the seat height. In addition, a pin is provided on the outside of the seat, moving along a slide. By contacting the inner wall of the slide, the pin enhances the overall limiting effect on the seat, preventing it from swaying during ascent or descent.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0032] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-8 As shown, the present invention is a grouting pipe unblocking device, including a frame 1, a telescopic component installed inside the frame 1, a seat 2 provided inside the frame 1, the end of the telescopic component being connected to the seat 2, the seat 2 having a cavity, and an outlet 202 provided at the bottom end of the seat 2, through which sewage generated during the cleaning process is discharged.

[0034] The base 2 has two opposing bayonets 203. One bayonet 203 contains a sleeve 5, which has a fixing member 4 that cooperates with the bayonet 203. A spring 6 located on the outside of the base 2 is sleeved on the sleeve 5. The other bayonet 203 contains a sleeve 7, which has a fixing member 4 that cooperates with the bayonet 203. Both sleeves 5 and 7 are sleeved on the screw 18. An impeller 19 is installed at one end of the screw 18. A gear 11 is installed inside the base 2 and is sleeved on the screw 18. A cover 9 is installed on the bayonet of the base 2. One side of the gear 11 passes through a strip groove 901 opened on the cover 9 and is connected to the drive assembly 10 for transmission.

[0035] The frame 1 includes a column 101 and a top rod 102. The top ends of two parallel columns 101 are connected by the top rod 102 to form an inverted U-shaped structure. The inner side of the column 101 is provided with a groove 104, and the bottom surface of the groove 104 is provided with a sliding groove 105.

[0036] Pins 201 and feet 3 are provided on opposite sides of the seat 2. The feet 3 are located on the upper side of the pins 201. The pins 201 move along the slide groove 105. The feet 3 are located in the groove 104. The telescopic component is a hydraulic telescopic column 20. The hydraulic telescopic column 20 is installed at the top of the groove 104. The telescopic end of the hydraulic telescopic column 20 is connected to the feet 3.

[0037] The inner part of the sleeve 2 7 is provided with a brush body, and the outer side of the sleeve 2 7 is provided with a frame 1. The fixing part 4 corresponding to the sleeve 2 7 is provided with a limiting groove 1. The force of the spring 2 8 is outward along the axis of the sleeve 2 7, and at the same time, the frame 1 cooperates with the corresponding limiting groove 1.

[0038] The sleeve body 5 has a protrusion inside, which moves along the thread on the outer surface of the screw 18. The sleeve body 5 has a protrusion 501, and the fixing part 4 corresponding to the sleeve body 5 has a limiting groove 2. The force of the spring 6 is outward along the sleeve body 5, and the protrusion 501 cooperates with the corresponding limiting groove 2.

[0039] The outer side of the screw 18 is provided with a limiting groove 1801 distributed along the axis. A bushing 12 is installed in the middle circular hole of the gear 11. The bushing 12 is composed of two semi-circular bushings spliced ​​together. The inner wall of the bushing 12 is provided with a protruding ridge 1201 that cooperates with the limiting groove 1801. The gear 11 drives the screw 18 to rotate synchronously through the bushing 12.

[0040] Several T-slots 1102 are distributed in a ring on the end face of the gear 11 near the sleeve 5. A slider 15 and a spring 16 are installed in the T-slots 1102. The ends of bolts 17 that pass through the spring 16 and the slider 15 are installed in the screw holes opened on the bottom surface of the T-slots 1102. The spring 16 pushes the slider 15 to fit against the bottom surface of the T-slots 1102. A connecting rod 14 is rotatably connected to the slider 15. Several connecting rods 14 are connected to the same gear ring 13. Several hinge seats are evenly distributed on the outer surface of the gear ring 13. The ends of the connecting rods 14 are installed on the corresponding hinge seats through pins.

[0041] The sleeve 5 has a ring 502 at one end near the gear 11. The ring 502 has teeth distributed in a ring at one end near the gear 11. The teeth of the toothed ring 13 face the ring 502. The ring 502 moves toward the toothed ring 13 to achieve mutual meshing between the ring 502 and the toothed ring 13.

[0042] When using grouting pipes, the installation height varies, so the height of the pipe dredging equipment needs to be adjusted during the cleaning process to ensure compatibility.

[0043] A wedge-shaped block 103 is provided at the bottom end of the column 101 to increase the contact area at the bottom end of the column 101, thereby improving the stability of the frame 1 during placement. A hydraulic telescopic column 20 is installed at the top of the groove 104. The telescopic end of the hydraulic telescopic column 20 is connected to the foot 3. By retracting the telescopic end of the hydraulic telescopic column 20, the foot 3 moves upward along the groove 104. By extending the hydraulic telescopic column 20, the foot 3 moves downward along the groove 104, thereby realizing the free adjustment of the height of the seat 2. In addition, a pin 201 that moves along the slide 105 is provided on the outside of the seat 2. By contacting the inner wall of the slide 105 with the pin 201, the limiting effect on the overall seat 2 is improved, and the seat 2 is prevented from swinging during the rising or falling process.

[0044] Gear 11 is located between sleeve 5 and sleeve 7, and one side of gear 11 is located in the strip groove 901. During operation, cover 9 does not move.

[0045] During the grouting pipe unblocking process, the drive assembly 10 is started. The drive assembly 10 consists of a motor and a transmission gear. The drive assembly 10 drives the gear 11 to rotate. Since the gear 11 is equipped with a bushing 12 that is in a limiting fit with the screw 18, the gear 11 drives the screw 18 to rotate synchronously.

[0046] The sleeve 5 is installed in the limiting hole formed by the bayonet 203 and the fixing member 4. The installed sleeve 5 slides along the axis of the limiting hole. Under the action of the spring 6, the outer end of the sleeve 5 is pushed outward until the protrusion 501 on the outer surface of the sleeve 5 engages with the corresponding limiting groove 2 of the fixing member 4. The engagement of the protrusion 501 with the limiting groove 2 restricts the rotation of the sleeve 5.

[0047] The inner surface of the sleeve 15 is provided with a protrusion. The surface of the protrusion is a spherical surface. The protrusion is engaged with the spiral groove provided on the outer surface of the screw 18. As the screw 18 rotates with the bushing 12, the protrusion moves along the spiral groove. Since the position of the sleeve 15 is fixed and the sleeve 15 does not rotate, the rotating screw 18 extends to the end where the impeller 19 is installed, so that the impeller 19 installed at the end of the screw 18 can continue to penetrate into the grouting pipe, which facilitates the cleaning of the grouting pipe.

[0048] When the impeller 19 is cleaning the grouting pipe, if the inside of the grouting pipe is blocked, and the impeller 19, which rotates with the screw 18, cannot cut the blockage, the rotating screw 18 cannot continue to go deeper. During the rotation of the screw 18, which cannot move along the axial direction, the reverse force on the protrusion and the sleeve 5 increases, thereby causing the sleeve 5 to move towards the gear 11 to compress the spring 6 until the protrusion 501 is disengaged from the limiting groove 2. This allows the spiral groove to drive the protrusion and the sleeve 5 to rotate synchronously, preventing the threaded rod from continuing to extend and causing damage to the impeller 19.

[0049] When the protrusion 501 disengages from the limiting groove 2, the teeth on the ring 502 mesh with the gear ring 13 to enable the gear 11 to drive the sleeve 5 to rotate synchronously. The transmission is achieved through the gear ring 13, which solves the problem of wear on the protrusion when the sleeve 5 is driven to rotate by the protrusion through the spiral groove for a long time.

[0050] In addition, the impeller 19 and the screw 18 are connected by a threaded fit. Depending on the inner diameter of the pipe to be cleaned, impellers 19 with different outer diameters can be selected for adaptation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
