Description

Technical Field

[0001] This utility model belongs to the field of grouting machine technology and relates to a drive mechanism for a grouting machine. Background Technology

[0002] Grouting machines are devices used for high-pressure injection of materials such as cement grout and chemical grout, and are widely used in construction, underground engineering, water conservancy seepage prevention, and foundation reinforcement. When performing two-component grouting operations, a drive mechanism is required to drive two grouting pipes to deliver the grout.

[0003] A smart cement-water glass dual-liquid grouting machine disclosed in Chinese patent CN222501976U has a power unit installed at the bottom of the main body of the grouting machine. The output end of the power unit is connected to the piston rod, which can drive the piston rod to slide up and down along the piston cylinder. The power unit includes a power motor, and the output end of the power motor is connected to a crank rocker mechanism. The upper end of the crank rocker mechanism is hinged to the bottom of the piston rod. The power motor drives the crank to rotate, and then the crank drives the rocker to move up and down reciprocally, ultimately driving the piston rod to move up and down along the piston cylinder, realizing the intake of mortar at the grout inlet and the spraying out of the grout outlet pipe.

[0004] The grouting machine uses two power motors on both sides to drive two piston rods, which increases production costs.

[0005] To solve the above problems, this utility model proposes a drive mechanism for a grouting machine. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a driving mechanism for a grouting machine.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a housing of a grouting machine, and two ends of the housing are horizontally slidably provided with sealing columns. A main shaft is fixedly connected between the two sealing columns, and a connecting plate is rotatably provided inside the main shaft.

[0008] The housing has a first rotating shaft rotatably mounted inside, and a rotating block is eccentrically fixed at the bottom end of the first rotating shaft. The rotating block is rotatably mounted inside one end of the connecting plate. The top of the housing has a rotating assembly that drives the first rotating shaft to rotate.

[0009] Furthermore, a feeding cylinder is fixedly installed at both ends of the housing, the main shaft is located between the two feeding cylinders, and the ends of the two sealing columns away from the main shaft are respectively horizontally slidably arranged in the two feeding cylinders.

[0010] Furthermore, one end of the main shaft is fixedly connected to two fixed plates from top to bottom, and the same vertically placed second rotating shaft is rotatably passed through the two fixed plates. The other end of the connecting plate is fixedly sleeved on the second rotating shaft.

[0011] Furthermore, the rotating assembly includes a motor, which is fixedly mounted above the housing. A first helical gear is fixedly sleeved on the bottom end of the motor's output shaft, and a second spur gear is fixedly sleeved on the first rotating shaft.

[0012] The housing is internally equipped with a transmission gear that meshes with a first helical gear and a second spur gear.

[0013] Furthermore, the transmission gear includes a second helical gear and a first spur gear, and a third rotating shaft is rotatably connected inside the housing. Both the third rotating shaft and the first rotating shaft are vertically arranged, and the second helical gear and the first spur gear are fixedly sleeved on the third rotating shaft from top to bottom.

[0014] The second helical gear meshes with the first helical gear, and the first spur gear meshes with the second spur gear.

[0015] Furthermore, a protective cover is fixedly connected to the top of the housing, and the motor is fixedly connected to the top of the housing. The bottom end of the motor's output shaft rotates through the top surface of the protective cover, and the first helical gear is located inside the protective cover.

[0016] The top of the third shaft rotates through the top surface of the housing and extends into the protective cover, while the second helical gear is located inside the protective cover.

[0017] Furthermore, a turntable is coaxially fixedly connected to the bottom of the first rotating shaft, and the rotating block is eccentrically fixedly connected to the bottom of the turntable.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The grouting machine's drive mechanism is equipped with a main shaft, which is fixedly connected between two sealing columns. The rotation of the first rotating shaft drives the turntable and rotating block to rotate. Due to the eccentric setting of the rotating block and the first rotating shaft, the rotating block pushes the connecting plate to swing back and forth within the main shaft when it rotates. The connecting plate pushes the main shaft to move back and forth, thereby driving the two sealing columns to move left and right synchronously. This allows the two conveying cylinders to alternately perform grouting work, eliminating the need for separate drive components and reducing production costs. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-6 As shown, the technical solution adopted by this utility model is as follows: A driving mechanism for a grouting machine includes a housing 1 of the grouting machine. Two sealing columns 2 are horizontally slidably arranged at both ends inside the housing 1, and a main shaft 3 is fixedly connected between the two sealing columns 2. The main shaft 3 connects the two sealing columns 2, so that when the main shaft 3 moves, it drives the two sealing columns 2 to move synchronously.

[0029] Both ends of the housing 1 are fixedly equipped with conveying cylinders 4, and the main shaft 3 is located between the two conveying cylinders 4. The ends of the two sealing columns 2 away from the main shaft 3 are respectively horizontally slidably disposed inside the two conveying cylinders 4. The conveying cylinders 4 are grouted by sliding the sealing columns 2 inside them.

[0030] Both ends of the housing 1 are fixedly connected to limiting cylinders 17, and the sealing column 2 slides through the corresponding limiting cylinders 17. The limiting cylinders 17 position the sealing column 2, increasing the stability of the movement of the sealing column 2.

[0031] The spindle 3 is internally equipped with a connecting plate 15 for rotation.

[0032] Two fixed plates are fixedly connected from top to bottom to one end of the main shaft 3, and the same vertically placed second rotating shaft 14 is rotatably passed through the two fixed plates. The other end of the connecting plate 15 is fixedly sleeved on the second rotating shaft 14. The connecting plate 15 is positioned inside the main shaft 3 by the cooperation of the second rotating shaft 14 and the fixed plates.

[0033] The housing 1 has a first rotating shaft 11 rotatably mounted inside. The bottom end of the first rotating shaft 11 is eccentrically fixed with a rotating block 13, which is rotatably mounted inside one end of the connecting plate 15.

[0034] A turntable 16 is coaxially fixedly connected to the bottom of the first rotating shaft 11, and a rotating block 13 is eccentrically fixedly connected to the bottom of the turntable 16. This allows the rotating block 13 to rotate around the rotation axis of the first rotating shaft 11.

[0035] A rotating assembly is provided at the top of the housing 1, which drives the first rotating shaft 11 to rotate.

[0036] The rotating assembly includes a motor 6, which is fixedly mounted above the housing 1. A first helical gear 7 is fixedly sleeved on the bottom end of the output shaft of the motor 6. A second spur gear 12 is fixedly sleeved on the first rotating shaft 11. The motor 6 drives the first helical gear 7 to rotate.

[0037] The housing 1 has a rotating transmission gear inside, which meshes with the first helical gear 7 and the second spur gear 12. The transmission gear causes the first helical gear 7 to drive the second spur gear 12 to rotate.

[0038] The transmission gears include a second helical gear 9 and a first spur gear 10. A third rotating shaft 8 is rotatably connected inside the housing 1, and both the third rotating shaft 8 and the first rotating shaft 11 are vertically arranged. The second helical gear 9 and the first spur gear 10 are fixedly mounted on the third rotating shaft 8 from top to bottom.

[0039] The second helical gear 9 meshes with the first helical gear 7. The first spur gear 10 meshes with the second spur gear 12. The first helical gear 7 drives the second helical gear 9 to rotate, which in turn drives the first spur gear 10 to rotate, thereby driving the second spur gear 12 to rotate, causing the first shaft 11 to rotate. At the same time, this has a deceleration effect on the output shaft of the motor 6, resulting in a lower rotation speed for the first shaft 11.

[0040] A protective cover 5 is fixedly connected to the top of the housing 1, and a motor 6 is fixedly connected to the top of the housing 1. The bottom end of the output shaft of the motor 6 rotates through the top surface of the protective cover 5, and the first helical gear 7 is located inside the protective cover 5.

[0041] The top of the third rotating shaft 8 rotates through the top surface of the housing 1 and extends into the protective cover 5, while the second helical gear 9 is located inside the protective cover 5.

[0042] Working principle:

[0043] In use, the motor 6 is started, and the output shaft of the motor 6 drives the first helical gear 7 to rotate, which in turn drives the second helical gear 9 to rotate. The second helical gear 9 drives the third rotating shaft 8 and the first spur gear 10 to rotate, and the first spur gear 10 drives the second spur gear 12 to rotate.

[0044] The second spur gear 12 drives the first rotating shaft 11 to rotate, causing the turntable 16 and the rotating block 13 to rotate. The rotating block 13 rotates around the rotation axis of the first rotating shaft 11.

[0045] The rotating block 13 will push the connecting plate 15 to swing back and forth inside the main shaft 3, so that the connecting plate 15 pushes the main shaft 3 to move back and forth through the second rotating shaft 14, driving the two sealing columns 2 to move back and forth synchronously, so that the two material conveying cylinders 4 alternately perform grouting work.

[0046] 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.
