Description

Technical Field

[0001] The invention relates to the technical field of road and bridge construction, in particular to a grouting device for road and bridge construction. Background Art

[0002] Road and bridge construction is a complex engineering project involving multiple technical fields and construction steps. The construction process usually includes key links such as preliminary preparation, organizational design, construction management, construction technology implementation and quality control. Preliminary preparation is the basis for ensuring the smooth progress of construction, including the formulation of construction plans, the review of construction drawings, the preparation of construction materials and equipment, etc. Organizational design is to formulate reasonable construction organization and technical measures according to the characteristics of the project and construction conditions. Construction management covers planning management, technical management, quality management, cost management and information management. Construction technology implementation is a specific construction activity, including the construction of roadbed, pavement, bridge substructure and superstructure, etc. Finally, quality control is an important link to ensure that the quality of the project meets the design requirements and relevant standards. In the construction of roads and bridges, grouting can effectively treat and reinforce the foundation, control groundwater, and prevent and control problems such as cracks and voids, which not only ensures the stability, safety and durability of the project, but also improves the construction efficiency and quality. Here, the present invention proposes a grouting device for road and bridge construction.

[0003] According to the search, Chinese patent literature, announcement number: CN212200092U, discloses a grouting device for road and bridge construction, which can stir the cement and concrete in the interval between the support plate frame and the guide plate frame through the setting of a driving motor, a positioning nut, a connecting frame, a positioning bolt, a driving roller, a driving track, a bearing, a screw rod and a stirring paddle, and the cement and concrete in the interval are also slowed down to ensure the normal operation of the grouting device and effectively improve the construction efficiency of roads and bridges. However, in actual use, the device needs to be manually filled with water and raw materials such as cement, which not only has a high work intensity, but also cannot accurately control the ratio of materials; in addition, the stirring paddle of the device is set large, so not only does the motor consume a lot of energy when it drives it to rotate, but it also cannot fully stir the materials at the bottom of the box, reducing the overall practicality. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a grouting device for road and bridge construction, which has the advantages of convenient operation, automatic feeding, improved mud quality and mixing efficiency, and solves the above-mentioned technical problems.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a grouting device for road and bridge construction, comprising a mixing barrel, a first motor, a feed pipe and a first water inlet pipe are fixedly installed on the top surface of the mixing barrel, a conveying pipe is fixedly connected to the top of the feed pipe, a second motor is fixedly installed on the bottom end of the conveying pipe, a first rotating shaft is installed inside the conveying pipe, a first spiral blade is fixedly installed on the outer side of the first rotating shaft, a feed port is fixedly installed on the outer side of the conveying pipe, a water pump is fixedly connected to the end of the first water inlet pipe away from the mixing barrel, a second water inlet pipe is fixedly connected to the right side of the water pump, a partition is fixedly installed inside the mixing barrel, a second rotating shaft and a third rotating shaft are fixedly installed inside the partition, a second spiral blade and a driving gear are fixedly installed on the outer side of the second rotating shaft, a third spiral blade and a driven gear are fixedly installed on the outer side of the third rotating shaft, a first discharge pipe is fixedly connected to the outer side of the mixing barrel, a grouting machine is fixedly installed at the front end of the first discharge pipe, and a second discharge pipe is fixedly connected to the front side of the grouting machine.

[0006] Preferably, the number of the feed pipe, the conveying pipe and the feed port is two.

[0007] Through the above technical solution, the material can be added to the interior of the mixing barrel by connecting the feed port to facilities such as storage silos. The two feed pipes, conveying pipes, feed ports and other parts can not only add different materials to the interior of the mixing barrel at the same time to improve work efficiency, but also when one set of equipment fails, the other set can also operate normally, avoiding delays in related work processes due to downtime and ensuring the normal operation of the device.

[0008] Preferably, the number of the second motor, the first rotating shaft and the first spiral blade is two, and the output shafts of the two second motors are respectively connected to the bottom ends of the two first rotating shafts.

[0009] Through the above technical solution, when the two second motors are started, the output shaft of the second motor can drive the first rotating shaft and the first spiral blade to rotate together, and the first spiral blade can then push the material to move upward along the conveying pipe. After that, the material can be transported to the inside of the mixing barrel through the feed pipe, effectively improving the overall conveying efficiency of the device.

[0010] Preferably, the bottom ends of the two feed pipes and the first water inlet pipe are both installed at the bottom of the partition.

[0011] Through the above technical solution, when the water pump is started, the water pump can transport water to the inside of the mixing barrel through the second water inlet pipe and the first water inlet pipe, and then can be effectively mixed with the material. The partition can not only prevent the material from splashing onto the driving gear and other parts during transportation to prevent them from being damaged, but also further play a protective role when stirring the material, thereby enhancing the overall practicality and stability.

[0012] Preferably, the output shaft of the first motor is fixedly connected to the top end of the second rotating shaft.

[0013] Through the above technical solution, when the first motor is started, the output shaft of the first motor can drive the second rotating shaft and the second spiral blade to rotate together, and the second spiral blade can form a spiral motion in the mixing barrel, pushing the material to produce a compound motion along the axis and tangential direction of the mixing barrel, thereby helping to fully mix various materials and components such as additives, and the second spiral blade can also continuously lift the material at the bottom of the mixing barrel, thereby further improving the uniformity of the material, thereby improving the mixing efficiency and mud quality.

[0014] Preferably, the number of the third rotating shaft and the number of the driven gears are both three, and the three driven gears are all meshedly connected to the outer side surface of the driving gear.

[0015] Through the above technical solution, when the first motor is started, the output shaft of the first motor can drive the second shaft and the driving gear to rotate together, and the driving gear can then engage and drive the three driven gears and the third shaft to rotate together. Therefore, when multiple spiral blades rotate together for stirring, not only is the force area smaller and the energy consumption lower, but the overall stirring efficiency is also improved.

[0016] Preferably, there are three third helical blades, and the spiral directions of the three third helical blades are opposite to the spiral direction of the second helical blades.

[0017] Through the above technical solution, when the driving gear indirectly drives the three third rotating shafts and the third spiral blades to rotate, since the driving gear and the driven gear rotate in opposite directions, the third spiral blade also rotates in the same direction as the second spiral blade when rotating and stirring, which not only improves the stirring efficiency and smoothness, but also prevents turbulence inside the mixing barrel, thereby ensuring the normal operation of the device.

[0018] Preferably, an electric valve is provided on the outer side of the first discharge pipe.

[0019] Through the above technical solution, when the device is stirred, the electric valve and the grouting machine are opened, and then the mud can be transported through the first discharge pipe and the second discharge pipe. When the device is stirred and the subsequent mud injection is completed, the electric valve can be closed. The electric valve can effectively ensure the sealing inside the device, thereby preventing material leakage.

[0020] Compared with the prior art, the present invention provides a grouting device for road and bridge construction, which has the following beneficial effects: 1. The present invention connects the feed port to the storage bin and other facilities and starts the second motor. The output shaft of the second motor can drive the first rotating shaft and the first spiral blade to rotate together. The first spiral blade can then push the material to move upward along the conveying pipe. After that, the material can be conveyed to the inside of the mixing barrel through the feed pipe. The two feed pipes, the conveying pipe, the feed port and other parts can not only simultaneously add different kinds of materials to the inside of the mixing barrel to improve work efficiency, but also when one set of equipment fails, the other set can also operate normally, avoiding delays in related work processes due to downtime, thereby ensuring the normal operation of the device; starting the water pump, the water pump can convey water to the inside of the mixing barrel through the second water inlet pipe and the first water inlet pipe, and then can effectively mix with the material.

[0021] 2. The present invention starts the first motor, and the output shaft of the first motor can drive the second rotating shaft, the second spiral blade and the driving gear to rotate together. The driving gear can then engage and drive the three driven gears and the third rotating shaft to rotate together. Therefore, the second spiral blade can stir together with the three third spiral blades. Multiple spiral blades can form a spiral motion in the mixing barrel, and push the material to produce a composite motion along the axis and tangential direction of the mixing barrel, which is helpful to fully mix various materials and components such as additives. The spiral blades can also continuously lift the material at the bottom of the mixing barrel, so that the uniformity of the material can be further improved, thereby improving the mixing efficiency and the mud quality. After that, when the device completes the mixing, the electric valve and the grouting machine can be opened, and the mud can be transported through the first discharge pipe and the second discharge pipe, thereby improving the overall work efficiency.
