Technical Field
[0001] This utility model relates to the field of bridge construction equipment technology, specifically a bridge construction grouting equipment. Background Technology
[0002] Grouting is a crucial step in bridge construction to ensure the stability and durability of the bridge structure.
[0003] In bridge construction grouting operations, uniform mixing of grouting materials is the core prerequisite for ensuring grouting quality. Grouting materials are usually made of cement, sand, gravel, additives and water in a specific ratio. The uniformity of mixing directly affects the strength, density and durability after hardening, and thus relates to the load-bearing capacity and service life of the bridge structure.
[0004] Traditional mixing devices suffer from insufficient mixing in practical applications. Most of these devices use a single-shaft, single-blade structure with blades that are mostly straight or simple paddle designs, which can only achieve localized stirring. This results in poor mixing effects, leading to localized agglomeration of materials or stratification of components, which directly affects the grouting effect.
[0005] In addition, most equipment has poor mobility, and when the position needs to be frequently adjusted on the construction site, it is inconvenient to operate and consumes a lot of time and manpower. Therefore, we propose a bridge construction grouting equipment to solve the above problems. Utility Model Content

A support frame is fixedly installed on the top of the mixing tank, and one end of a lead screw is fixedly installed at the center of the support frame. A ball screw nut is threaded onto the other end of the lead screw, and a rotating shaft is fixedly connected to the bottom of the ball screw nut.

[0008] The bottom of the mixing tank is connected to a conveying pipe, and an auger is rotatably connected inside the conveying pipe. The central shaft of the auger rotates through the conveying pipe and is then fixedly connected to the output shaft of a motor. The motor is fixedly connected to the top of the base. One end of the conveying pipe is fixedly connected to a flexible hose through a flange, and the other end of the flexible hose is fixedly connected to a grouting head.
[0009] Preferably, the lead screw rotates through the ball screw nut and then slides onto the rotating shaft.

[0024] 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.
[0025] Example 1
[0026] Reference Figure 1-6This is the first embodiment of the present invention, which provides a bridge construction grouting device, including a base 1. Multiple support columns 2 are fixedly connected to one end of their respective top ends. The other ends of the support columns 2 are fixedly connected to the bottom perimeter of a mixing tank 3. A support frame 4 is fixedly installed at the top of the mixing tank 3. A lead screw 5 is fixedly installed at one end of the center of the support frame 4. A ball screw nut 6 is threaded onto the other end of the lead screw 5. A rotating shaft 7 is fixedly connected to the bottom of the ball screw nut 6. Multiple mixing blades 8 are fixedly installed on the rotating shaft 7. The mixing blades 8 are movably disposed inside the mixing tank 3. The ball screw nut 6 is rotatably sleeved onto the connecting shaft. 9. Sliding columns 10 are fixedly connected to both ends of the connecting shaft 9. The sliding columns 10 are slidably connected to the sliding grooves 11, which are respectively opened on both sides of the mixing tank 3. An annular bracket 12 is fixedly installed on one of the sliding columns 10. A rack 13 is fixedly installed on opposite sides of the annular bracket 12. The rack 13 meshes with a half gear 14. A rotating rod 15 is fixedly connected to the center of the half gear 14. The rotating rod 15 rotates through the mounting frame 16 and is then driven by a fixed pulley to one side of the belt 17. The mounting frame 16 is fixedly installed on the outer wall of the mixing tank 3. The other side of the belt 17 is driven and fixedly connected to the motor 18. The output shaft pulley and motor 18 are fixedly connected to the top of the base 1. The motor 18 drives the belt 17 to rotate via the pulley. The rotation of the belt 17 further drives the rotating rod 15 to rotate. The rotating rod 15 drives the half gear 14 to rotate. The half gear 14, through meshing with the racks 13 on both sides of the annular bracket 12, further drives the annular bracket 12 to reciprocate vertically. This further drives the ball screw nut 6 to move up and down. The ball screw nut 6 further drives the rotating shaft 7 to move synchronously. While the ball screw nut 6 moves up and down, it meshes with the screw 5, thereby driving the ball screw nut 6 through movement. The ball screw nut 6 drives the rotating shaft 7 to rotate synchronously. The up-and-down movement and rotation of the rotating shaft 7 further drive the mixing blades 8 to rotate and move up and down. The rotation of the mixing blades 8, combined with the up-and-down movement of the mixing blades 8, stirs the material. During the up-and-down movement, the mixing blades 8 can carry the upper layer of material to the lower layer and flip the lower layer of material to the upper layer, breaking the stratification of the material. This ensures that the grouting material is fully stirred, guarantees the performance stability of the grouting material, greatly improves the stirring efficiency, shortens the stirring time, and thus speeds up the grouting operation progress of bridge construction.
[0027] A conveying pipe 19 is connected to the bottom of the mixing tank 3. An auger 20 is rotatably connected inside the conveying pipe 19. The central shaft of the auger 20 rotates through the conveying pipe 19 and is fixedly connected to the output shaft of the motor 18. The motor 18 is fixedly connected to the top of the base 1. One end of the conveying pipe 19 is fixedly connected to the flexible hose 22 through a flange. The other end of the flexible hose 22 is fixedly connected to the grouting head 23. The auger 20 conveys the grouting material in the conveying pipe 19 into the flexible hose 22 by rotating. After passing through the flexible hose 22, the grouting material is output through the grouting head 23 to grout the construction site. The designed auger 20 conveys the material to avoid blockage of the conveying pipe 19 during the conveying process. At the same time, the rotation of the auger 20 and the rotation of the mixing blades 8 share the same power source, reducing the number of devices, lowering the purchase and maintenance costs, reducing the weight of the equipment, and enhancing the mobility.
[0028] Example 2
[0029] Reference Figure 1-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the lead screw 5 rotates through the ball screw nut 6 and then slides onto the rotating shaft 7. The ball screw nut 6 drives the rotating shaft 7 to move up and down. While the ball screw nut 6 moves up and down, it engages with the lead screw 5, thereby driving the ball screw nut 6 to rotate. The ball screw nut 6 drives the rotating shaft 7 to rotate synchronously, thereby driving the stirring blades 8 to rotate and stir, further stirring the grout material and ensuring the uniformity of the grout material.
[0030] The number of teeth on the half gear 14 is the same as the number of teeth on one side of the rack 13 on the annular support 12. The half gear 14 meshes with the rack 13 by rotating. When the half gear 14 rotates one revolution, it first meshes and drives one side of the rack 13 to move upward. Then it meshes and drives the other side of the rack 13 to move downward. This further drives the annular support 12 to move up and down, and further drives the sliding column 10 to move synchronously. This in turn drives the stirring blade 8 to move up and down. During the up and down movement, the upper layer of material can be carried to the lower layer, and the lower layer of material can be turned to the upper layer. This breaks the stratification of the material and ensures that the grouting material can be fully mixed, thus ensuring the performance stability of the grouting material.
[0031] Multiple support rings 21 are fixedly sleeved on the outside of the conveying pipe 19. The support rings 21 are fixedly connected to the top surface of the base 1. The conveying pipe 19 is supported by the support rings 21 to ensure the stability of the device operation.
[0032] A pull rod 24 is fixedly installed on one side of the top of the base 1. The device can be moved by the pull rod 24 in conjunction with the caster wheel 25, which improves the ease of movement of the device.
[0033] The base 1 is fixedly connected to casters 25 around its bottom. The casters 25 are used to move the device, improving the flexibility of the device's movement.
[0034] In use, materials are added into the mixing tank 3, and then the motor 18 is started. The motor 18 drives the belt 17 to rotate via the pulley. The rotation of the belt 17 further drives the rotating rod 15 to rotate. The rotating rod 15 drives the half gear 14 to rotate. The half gear 14 meshes with the racks 13 on both sides of the annular bracket 12, further driving the annular bracket 12 to move up and down in the vertical direction. While the annular bracket 12 moves, the sliding column 10 moves synchronously. The sliding column 10 drives the connecting shaft 9 to move synchronously. The connecting shaft 9 further drives the ball screw nut 6 to move up and down. The ball screw nut 6 further drives the rotating shaft 7 to move synchronously. Simultaneously, the screw 5 engages, which in turn drives the ball screw nut 6 to rotate. The ball screw nut 6 drives the rotating shaft 7 to rotate synchronously. The up-and-down movement and rotation of the rotating shaft 7 further drives the mixing blades 8 to rotate and move up and down. The rotation of the mixing blades 8, combined with their up-and-down movement, stirs the material. During the up-and-down movement, the mixing blades 8 can carry the upper layer of material to the lower layer and flip the lower layer of material to the upper layer, breaking the stratification of the material. This ensures that the grouting material is fully stirred, guarantees the performance stability of the grouting material, greatly improves the stirring efficiency, shortens the stirring time, and thus accelerates the grouting operation progress of bridge construction.
[0035] After being mixed, the grouting material in the mixing tank 3 enters the conveying pipe 19. The motor 18 drives the belt 17 to rotate while simultaneously driving the central shaft of the auger 20 to rotate. The auger 20, through its rotation, conveys the grouting material in the conveying pipe 19 to the hose 22. After passing through the hose 22, the grouting material is output through the grouting head 23 to grout the construction site. The designed auger 20 conveys the material, avoiding blockage in the conveying pipe 19 during the conveying process. At the same time, the rotation of the auger 20 and the rotation of the mixing blades 8 share the same power source, reducing the number of devices, lowering procurement and maintenance costs, reducing equipment weight, and enhancing mobility.
