Description

Technical Field

[0001] This utility model belongs to the technical field of grouting devices, and relates to a device for preventing blockage of cement-based grouting materials for supports. Background Art

[0002] Bridge bearing grout is suitable for emergency repairs, track filling, and bearing grouting, especially for high-speed railway bridge bearings or track filling, and can also be used for the repair of cement-based bearings. However, when grouting cement-based bearings, if the grouting time is too long, the grout is prone to solidification and blockage, thus requiring an anti-blocking device.

[0003] A grouting machine capable of preventing blockage is disclosed in Chinese patent CN217198755U. It includes a grouting machine, a grouting bottle disposed on one side of the grouting machine, a grouting pipe disposed on the other side of the grouting machine, and a dredging component disposed inside the grouting bottle. The dredging component includes a fixed sleeve, a piston rod, a crank arm, a hinge, a wheel, and a crank pin. The wheel is movably connected to one end of the crank arm through the crank pin. The other end of the crank arm is hinged to the piston rod through the hinge. A conical needle is installed on the other end of the piston rod connected to the hinge. The conical needle extends through the grouting bottle to the outside of the grouting bottle.

[0004] When dredging, this grouting machine moves the piston rod by rotating the turntable, and then rotates the knob to make the grouting ring swing. This requires operators to separately operate the turntable and the knob, making it inconvenient to use.

[0005] A concrete pouring device for preventing blockage is disclosed in Chinese patent CN218715206U, comprising: a control room, with a bottom wheel installed at each of the four corners of the bottom end of the control room, a switch door installed on the surface of the control room, and a front frame installed at the front end of the control room; a sliding groove is provided on the front side of each end of the front frame, and a slider is slidably installed in the sliding groove.

[0006] When using this casting device, starting motor one causes the casting box to vibrate, and starting motor two causes the mixing block to rotate. This necessitates driving two motors separately, increasing production costs.

[0007] To address the aforementioned problems, this utility model proposes an anti-clogging device for cement-based grouting materials in bearings. Utility Model Content

When the first rotating shaft rotates, the transmission assembly drives the first rotating shaft to move up and down reciprocally.

[0012] Furthermore, a pump body is fixedly connected to the top of the grouting machine. The input pipe and output pipe of the pump body both penetrate the top surface of the grouting machine and extend into the interior of the grouting machine. A grouting pipe is fixedly connected to the end of the output pipe of the pump body, and the grouting pipe is fixedly connected to the side of the grouting machine.

[0013] Furthermore, a support plate is fixedly connected to the top of the grouting machine, and a buckle is fixedly connected to one side of the support plate. One end of the grouting pipe extending outside the grouting machine is secured to the buckle.

[0014] Furthermore, a cross-shaped fixing rod is fixedly connected to the inner wall of the grouting machine, and the first rotating shaft slides through the fixing rod. The fixing rod is located below the mixing plate and above the mixing rod.

[0015] Furthermore, the drive assembly includes a motor, which is fixedly connected to the top of the grouting tank. A first gear is fixedly sleeved on the output shaft of the motor. The first rotating shaft slides through the top surface of the grouting tank. A first slider is fixedly connected to the top of the first rotating shaft. The first slider is a rectangular block.

[0016] The top of the grouting tank is rotatably connected to a rotating cylinder, which is an inverted barrel shape. The shape inside the rotating cylinder is adapted to the first slider. The first slider is vertically slidably connected to the inside of the rotating cylinder. A second gear is fixedly sleeved on the outer surface of the top of the rotating cylinder, and the second gear meshes with the first gear.

[0017] The top of the grouting tank is fixedly connected to an annular positioning ring, which has an L-shaped cross-section. The bottom end of the rotating drum is rotatably connected to the positioning ring.

[0018] Furthermore, the transmission assembly includes a fixed cylinder, which is fixedly connected to the top surface of the inner cavity of the grouting tank. The fixed cylinder has a barrel-shaped structure. The fixed cylinder, the first rotating shaft, the positioning ring, and the rotating cylinder are arranged coaxially. The first rotating shaft slides through the fixed cylinder. An annular arc-shaped groove is provided on the inner wall of the fixed cylinder. The arc-shaped groove is inclined.

[0019] A connecting rod is fixedly connected to the outer surface of the first rotating shaft, and a second slider is fixedly connected to the end of the connecting rod. The second slider is slidably connected to the inside of the arc-shaped groove.

[0020] Furthermore, the transmission assembly includes a top plate, which is an inverted barrel shape, with the bottom surface of the top plate being an annular inclined surface. The top plate is coaxially and fixedly connected to the top end of the motor's output shaft.

[0021] The top of the first slider is coaxially fixedly connected to a second rotating shaft, the second rotating shaft slides through the top surface of the rotating cylinder, the top of the second rotating shaft is fixedly connected to a fixing block, and the top plate is slidably connected to the top surface of the fixing block;

[0022] A spring is fitted on the second rotating shaft. One end of the spring is fixedly connected to the bottom surface of the fixed block, and the other end of the spring is fixedly connected to the top of the rotating cylinder.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The anti-clogging device for cement-based grouting material in this support is equipped with an arc-shaped sliding groove. The arc-shaped sliding groove is inclined. When using the grouting tank, the motor is started to drive the first gear to rotate, which in turn drives the second gear, the rotating drum, the first slider, and the first rotating shaft to rotate. This causes the mixing plate and the mixing rod to rotate. When the first rotating shaft drives the second slider to rotate, the second slider slides along the trajectory of the arc-shaped sliding groove. The second slider drives the first rotating shaft to move up and down, which in turn causes the mixing plate and the mixing rod to move up and down while rotating, stirring the grout in the grouting tank and the discharge pipe, preventing the grout from solidifying and achieving the purpose of anti-clogging. Furthermore, the first rotating shaft is driven to rotate and move up and down by the motor, eliminating the need for separate drives, making the operation simple and more convenient.

[0025] 2. The cement-based grouting anti-clogging device for this support is equipped with a top plate, which is an inverted barrel shape, and the bottom surface of the top plate is an annular inclined surface. When the motor drives the first rotating shaft to rotate, it will also drive the top plate to rotate. When the bottommost end of the bottom surface of the top plate moves towards the fixed block, the top plate gradually presses the fixed block downward. The fixed block moves downward and compresses the spring, causing the first rotating shaft to move downward. When the topmost end of the bottom surface of the top plate moves towards the fixed block, the spring gradually extends and pushes the fixed block and the first rotating shaft to move upward. Thus, the first rotating shaft is driven to rotate and move up and down by the motor, eliminating the need for separate drives and reducing production costs. Attached Figure Description

[0032] The following will be combined with the drawings in 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 creative efforts are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: a cement-based grouting material anti-blocking device for supports, including a grouting machine 1, with support wheels installed at the four corners of the bottom surface of the grouting machine 1.

[0034] A pump body 4 is fixedly connected to the top of the grouting machine 1.

A grouting pipe 3 is fixedly connected to the end of the output pipe of the pump body 4, and the grouting pipe 3 is fixedly connected to the side of the grouting machine 1. The grouting pipe 3 is a flexible hose. When the pump body 4 is started, the grout inside the grouting machine 1 is fed into the grouting pipe 3, and finally sprayed out through the end of the grouting pipe 3.

[0035] A support plate 2 is fixedly connected to the top of the grouting machine 1, and a buckle is fixedly connected to one side of the support plate 2. One end of the grouting pipe 3 extending outside the grouting machine 1 is secured to the buckle. In use, one end of the grouting pipe 3 can be positioned on the buckle for storage.

[0036] A grouting tank 5 is fixedly installed above the grouting machine 1, and a feed pipe 6 is fixedly connected to the top of the grouting tank 5. Grout is introduced into the grouting tank 5 through the feed pipe 6. A discharge pipe 7 is fixedly connected to the bottom of the grouting tank 5, and the bottom end of the discharge pipe 7 is fixedly connected to the feed port of the grouting machine 1. This allows the grout in the grouting tank 5 to be introduced into the grouting machine 1 through the discharge pipe 7.

[0037] A first rotating shaft 13 is movably mounted inside the grouting tank 5. A plurality of stirring plates 18 are uniformly fixedly connected to the outer surface of the middle portion of the first rotating shaft 13. The stirring plates 18 are arranged in a circumferential array about the first rotating shaft 13, causing them to stir the grout within the grouting tank 5. A plurality of stirring rods 20 are uniformly fixedly connected to the outer surface of the bottom end of the first rotating shaft 13. The stirring rods 20 are movably mounted inside the discharge pipe 7. The stirring rods 20 are arranged in a circumferential array about the first rotating shaft 13, causing them to agitate the grout within the discharge pipe 7.

[0038] A drive assembly is provided on the top of the grouting tank 5, which drives the first rotating shaft 13 to rotate.

[0039] The drive assembly includes a motor 8, which is fixedly connected to the top of the grouting tank 5. A first gear 9 is fixedly sleeved on the output shaft of the motor 8. A first rotating shaft 13 slides through the top surface of the grouting tank 5, and a first slider 12 is fixedly connected to the top of the first rotating shaft 13. The first slider 12 is a rectangular block.

[0040] A rotating cylinder 11, which is an inverted barrel shape, is rotatably connected to the top of the grouting tank 5. The internal shape of the rotating cylinder 11 is adapted to the first slider 12, which is vertically slidably connected to the inside of the rotating cylinder 11 and can only slide up and down inside the rotating cylinder 11. A second gear 10 is fixedly sleeved on the outer surface of the top end of the rotating cylinder 11, and the second gear 10 meshes with the first gear 9.

[0041] A ring-shaped positioning ring 25 is fixedly connected to the top of the grouting tank 5. The positioning ring 25 has an L-shaped cross-section. The bottom end of the rotating drum 11 is rotatably connected to the positioning ring 25. The positioning ring 25 positions the rotating drum 11.

[0042] A cross-shaped fixing rod 19 is fixedly connected to the inner wall of the grouting machine 1, and the first rotating shaft 13 slides through the fixing rod 19. The fixing rod 19 is located below the mixing plate 18 and above the mixing rod 20. The fixing rod 19 positions the first rotating shaft 13.

[0043] The grouting tank 5 is equipped with a transmission assembly, which works in conjunction with the drive assembly. When the first rotating shaft 13 rotates, the transmission assembly drives the first rotating shaft 13 to move up and down reciprocally.

[0044] The transmission assembly includes a fixed cylinder 14. The fixed cylinder 14 is fixedly connected to the top surface of the inner cavity of the grouting tank 5, and the fixed cylinder 14 has a barrel-shaped structure. The fixed cylinder 14, the first rotating shaft 13, the positioning ring 25, and the rotating cylinder 11 are arranged coaxially, and the first rotating shaft 13 slides through the fixed cylinder 14. An annular arc-shaped groove 15 is formed on the inner wall of the fixed cylinder 14, and the arc-shaped groove 15 is inclined.

[0045] A connecting rod 16 is fixedly connected to the outer surface of the first rotating shaft 13, and a second slider 17 is fixedly connected to the end of the connecting rod 16. The second slider 17 is slidably connected inside the arc-shaped groove 15. When the second slider 17 slides inside the arc-shaped groove 15, it will move along the trajectory of the arc-shaped groove 15, and the second slider 17 drives the first rotating shaft 13 to move up and down reciprocally.

[0046] Working principle:

[0047] In use, the grout is fed into the grouting tank 5 through the feed pipe 6, and then flows into the grouting machine 1 through the discharge pipe 7. The grouting pipe 3 is removed from the support plate 2, and one end of the grouting pipe 3 is aligned with the area to be grouted on the support. The pump body 4 is started, causing the grout to be sprayed out through the grouting pipe 3.

[0048] During the grouting process, motor 8 is started. The output shaft of motor 8 drives the first gear 9 to rotate, and the first gear 9 drives the second gear 10 to rotate, causing the rotating drum 11 to rotate, which in turn drives the first slider 12 and the first rotating shaft 13 to rotate. This causes the mixing plate 18 to rotate and stir the grout in the grouting tank 5, while simultaneously driving the mixing rod 20 to rotate and stir the grout in the discharge pipe 7.

[0049] The first rotating shaft 13 drives the connecting rod 16 and the second slider 17 to rotate, causing the second slider 17 to slide inside the arc-shaped groove 15. As the second slider 17 slides along the trajectory of the arc-shaped groove 15, it drives the first rotating shaft 13 to move up and down, thereby causing the stirring plate 18 and the stirring rod 20 to move up and down simultaneously with the rotation. This agitates the slurry in the grouting tank 5 and the discharge pipe 7, preventing the slurry from solidifying and achieving the purpose of preventing blockage.

[0050] Example 2: Figures 4-5 As shown, the anti-clogging device for cement-based grouting material of the support includes a grouting machine 1, and support wheels are installed at the four corners of the bottom surface of the grouting machine 1.

[0051] A pump body 4 is fixedly connected to the top of the grouting machine 1. The input and output pipes of the pump body 4 both penetrate the top surface of the grouting machine 1 and extend into its interior. A grouting pipe 3 is fixedly connected to the end of the output pipe of the pump body 4, and the grouting pipe 3 is fixedly connected to the side of the grouting machine 1. When the pump body 4 is started, the grout inside the grouting machine 1 is fed into the grouting pipe 3, and finally ejected through the end of the grouting pipe 3.

[0052] A support plate 2 is fixedly connected to the top of the grouting machine 1, and a buckle is fixedly connected to one side of the support plate 2. One end of the grouting pipe 3 extending outside the grouting machine 1 is secured to the buckle. When not in use, one end of the grouting pipe 3 can be positioned on the buckle for storage.

[0053] A grouting tank 5 is fixedly installed above the grouting machine 1, and a feed pipe 6 is fixedly connected to the top of the grouting tank 5. Grout is introduced into the grouting tank 5 through the feed pipe 6. A discharge pipe 7 is fixedly connected to the bottom of the grouting tank 5, and the bottom end of the discharge pipe 7 is fixedly connected to the feed port of the grouting machine 1. This allows the grout in the grouting tank 5 to be introduced into the grouting machine 1 through the discharge pipe 7.

[0054] A first rotating shaft 13 is movably mounted inside the grouting tank 5. A plurality of stirring plates 18 are uniformly fixedly connected to the outer surface of the middle portion of the first rotating shaft 13. The stirring plates 18 are arranged in a circumferential array about the first rotating shaft 13, causing them to stir the grout within the grouting tank 5. A plurality of stirring rods 20 are uniformly fixedly connected to the outer surface of the bottom end of the first rotating shaft 13. The stirring rods 20 are movably mounted inside the discharge pipe 7. The stirring rods 20 are arranged in a circumferential array about the first rotating shaft 13, causing them to agitate the grout within the discharge pipe 7.

[0055] A drive assembly is provided on the top of the grouting tank 5, which drives the first rotating shaft 13 to rotate.

[0056] The drive assembly includes a motor 8, which is fixedly connected to the top of the grouting tank 5. A first gear 9 is fixedly sleeved on the output shaft of the motor 8. A first rotating shaft 13 slides through the top surface of the grouting tank 5, and a first slider 12 is fixedly connected to the top of the first rotating shaft 13. The first slider 12 is a rectangular block.

[0057] A rotating cylinder 11, which is an inverted barrel shape, is rotatably connected to the top of the grouting tank 5. The internal shape of the rotating cylinder 11 is adapted to the first slider 12, which is vertically slidably connected to the inside of the rotating cylinder 11 and can only slide up and down inside the rotating cylinder 11. A second gear 10 is fixedly sleeved on the outer surface of the top end of the rotating cylinder 11, and the second gear 10 meshes with the first gear 9.

[0058] A ring-shaped positioning ring 25 is fixedly connected to the top of the grouting tank 5. The positioning ring 25 has an L-shaped cross-section. The bottom end of the rotating drum 11 is rotatably connected to the positioning ring 25. The positioning ring 25 positions the rotating drum 11.

[0059] A cross-shaped fixing rod 19 is fixedly connected to the inner wall of the grouting machine 1, and the first rotating shaft 13 slides through the fixing rod 19. The fixing rod 19 is located below the mixing plate 18 and above the mixing rod 20. The fixing rod 19 positions the first rotating shaft 13.

[0060] The grouting tank 5 is equipped with a transmission assembly, which works in conjunction with the drive assembly. When the first rotating shaft 13 rotates, the transmission assembly drives the first rotating shaft 13 to move up and down reciprocally.

[0061] The transmission assembly includes a top plate 24. The top plate 24 is an inverted barrel shape, and its bottom surface is an annular inclined surface. The top plate 24 is coaxially fixed to the top end of the output shaft of the motor 8. When the motor 8 is started, the output shaft of the motor 8 will drive the top plate 24 and the first gear 9 to rotate together.

[0062] The top of the first slider 12 is coaxially fixedly connected to the second rotating shaft 21, which slides through the top surface of the rotating cylinder 11. The top of the second rotating shaft 21 is fixedly connected to the fixing block 23, and the top plate 24 is slidably connected to the top surface of the fixing block 23.

[0063] A spring 22 is fitted onto the second rotating shaft 21. One end of the spring 22 is fixedly connected to the bottom surface of the fixing block 23, and the other end of the spring 22 is fixedly connected to the top of the rotating cylinder 11.

[0064] Working principle:

[0065] In use, the grout is fed into the grouting tank 5 through the feed pipe 6, and then flows into the grouting machine 1 through the discharge pipe 7. The grouting pipe 3 is removed from the support plate 2, and one end of the grouting pipe 3 is aligned with the area to be grouted on the support. The pump body 4 is started, causing the grout to be sprayed out through the grouting pipe 3.

[0066] During the grouting process, motor 8 is started. The output shaft of motor 8 drives the first gear 9 to rotate, and the first gear 9 drives the second gear 10 to rotate, causing the rotating drum 11 to rotate, which in turn drives the first slider 12 and the first rotating shaft 13 to rotate. This causes the mixing plate 18 to rotate and stir the grout in the grouting tank 5, while simultaneously driving the mixing rod 20 to rotate and stir the grout in the discharge pipe 7.

[0067] The output shaft of motor 8 simultaneously drives the top plate 24 to rotate. Since the bottom surface of the top plate 24 is an annular inclined surface, as the bottommost end of the top plate 24 moves towards the fixed block 23, the top plate 24 gradually presses down on the fixed block 23. This causes the fixed block 23 to move downwards and compress the spring 22. This causes the second rotating shaft 21 to move downwards, and the first slider 12 slides downwards inside the rotating cylinder 11, driving the first rotating shaft 13, the stirring plate 18, and the stirring rod 20 to move downwards.

[0068] When the top edge of the bottom surface of the top plate 24 moves towards the fixed block 23, the spring 22 gradually extends under the action of its elastic force, pushing the fixed block 23 upward so that it remains in contact with the top plate 24. This causes the second rotating shaft 21 to move upward, which in turn moves the first slider 12, the first rotating shaft 13, the stirring plate 18, and the stirring rod 20 upward. The stirring plate 18 and the stirring rod 20 move up and down while rotating, agitating the slurry in the grouting tank 5 and the discharge pipe 7, preventing the slurry from solidifying and thus preventing blockage.

[0069] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
