Abstract
Description
Technical Field
[0001] This utility model relates to the field of grouting technology, and in particular to an auxiliary device for grouting inside steel columns. Background Technology
[0002] Grouting auxiliary devices for steel columns are tools that play a supporting role in the grouting process inside steel columns, such as grouting funnels and guide pipes. These auxiliary devices are needed because the internal space of a steel column is unique, making it difficult to ensure the uniformity and density of the grout through direct pouring. The auxiliary devices guide the grout material smoothly into all parts of the column, effectively avoiding quality problems such as voids and gaps during grouting, thus ensuring the quality of the grouting.
[0003] A typical steel column grouting auxiliary device includes a grouting funnel, a guide pipe, and a sealing component. The grouting funnel stores and guides the grout, allowing it to flow into the steel column in a controlled manner. The guide pipe primarily transports the grout from the funnel to the depths of the steel column, ensuring it reaches all parts of the column. The sealing component seals any openings in the steel column during grouting, preventing leakage. Its working principle is as follows: the grout is poured into the funnel, transported through the guide pipe to the inside of the steel column, and, with the assistance of the sealing component, fully fills the steel column. Relying on gravity and the grout's own fluidity, it evenly fills the internal space of the steel column, ensuring grouting quality.
[0004] The materials required by the existing technology still need to be specially purchased and manufactured, and the manufacturing requirements are high. In actual construction, special tightening belts are also needed for fixation, but the tightening belts are subject to wear and tear. The guide pipes used need to be determined according to the diameter of the grouting port. When the guide pipe is inserted into the grouting hole, the grouting height cannot be determined in time during the grouting process, which can lead to unnecessary waste of grouting material. Therefore, an auxiliary device for grouting inside steel columns is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an auxiliary device for grouting inside steel columns, which aims to improve the existing technology's difficulty in grouting steel columns with grouting ports of different sizes, types, and heights, as well as the difficulty in ensuring simple operation, strong applicability, simple and convenient manufacturing, and cost-effectiveness and environmental protection.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grouting auxiliary device for steel columns, comprising a grouting hopper, a support mechanism rotatably connected to the bottom of the grouting hopper, an adjusting mechanism detachably connected to the top of the grouting hopper, a limiting component fixedly connected to the outer wall of the adjusting mechanism, the support mechanism comprising a connecting stud, the connecting stud being rotatably connected to the bottom of the grouting hopper, two nuts threadedly connected to both ends of the connecting stud, two fixed cylinders fixedly connected to both ends of the connecting stud, fixed support legs fixedly connected to the outer wall of the fixed cylinders, two blocking rods fixedly connected to the middle of the two fixed support legs, and a driving component fixedly connected to the bottom of the grouting hopper.

[0008] As a further description of the above technical solution: the adjusting mechanism includes a support plate, the bottom of which is detachably connected to the bottom of the grouting hopper, an outer tube is rotatably connected to the middle of the support plate, a drive nut is threadedly connected to the outer wall of one end of the outer tube, a rotating plate is fixedly connected to the outer wall of the other end of the outer tube, an inner tube is rotatably connected to the inner wall of the outer tube, a drive thread is threadedly connected to the outer wall of one end of the inner tube, and a rotating plate is fixedly connected to the other end of the inner tube.
[0009] As a further description of the above technical solution: the limiting component includes two partitions, the outer walls of the two partitions are respectively fixedly connected to the outer wall of the other end of the rotating plate one and the outer wall of the other end of the rotating plate two, and a limiting ring is fixedly connected to the outer wall of the partition.
[0010] As a further description of the above technical solution: the top of the support plate is threaded with two screws, and the bottom of the two screws is threaded to the top of the grouting hopper.
[0011] As a further description of the above technical solution: the outer wall of the butterfly nut is in contact with the outer walls of the two barrier rods.
[0012] As a further description of the above technical solution: the bottom outer wall of the first rotating plate is slidably connected to the top inner wall of the grouting hopper, and the bottom outer wall of the second rotating plate is slidably connected to the top inner wall of the grouting hopper.

[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, by inserting the grouting hopper into the grouting port of the steel column, rotating the first nut connects the fixed support leg to the steel column through the transmission action of the connecting stud and the fixed cylinder. Then, rotating the second nut and the butterfly nut causes the butterfly nut to squeeze the barrier rod, thereby adjusting the grouting angle and fixing the support leg. This ensures a stable connection between the grouting hopper and the steel column, enabling convenient angle adjustment and stable support of the grouting hopper. This allows the grouting hopper to accurately match the angle of the steel column grouting port, ensuring smooth and efficient injection of grout, improving the accuracy of grouting operations, and preventing shaking and displacement. This ensures a stable and safe grouting process and guarantees construction quality.
[0016] 2. In this utility model, by rotating the first and second drive nuts, the outer and inner tubes are driven to rotate. The two partitions are driven to rotate by the transmission action of the first and second rotating plates, thereby adjusting the spacing between the partitions so that the outlet corresponds to the grouting port. With the help of the limiting ring, all the grouting material enters between the two partitions to smoothly carry out the grouting operation. This allows the grouting auxiliary device to change the size of the outlet at any time according to the different sizes of grouting ports on site, which enhances the adaptability of the grouting auxiliary device. It can be flexibly applied to the grouting work of steel columns of various specifications without the need to change equipment, thus improving the versatility of the device.

[0025] 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.
[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a grouting auxiliary device for steel columns, including a grouting hopper 1. The grouting hopper 1 serves as the core container component of the entire auxiliary device, containing the grouting material. A support mechanism 2 is rotatably connected to the bottom of the grouting hopper 1, and an adjusting mechanism 3 is detachably connected to the top of the grouting hopper 1. A limiting component is fixedly connected to the outer wall of the adjusting mechanism 3.
[0027] The support mechanism 2 includes a connecting stud 201, which is rotatably connected to the bottom of the grouting hopper 1. The connecting stud 201 provides a rotational support point for the subsequent support mechanism 2. Two nuts 202 are threaded to both ends of the connecting stud 201. During use, the rotation of the nuts 202 drives the connecting stud 201 to rotate. Two fixed cylinders 203 are fixedly connected to both ends of the connecting stud 201. The fixed cylinders 203 transmit the rotation of the connecting stud 201 to the subsequent structure, thereby driving the subsequent structure to rotate. Fixed support legs 204 are fixedly connected to the outer wall of the fixed cylinders 203. The two fixed support legs 204 are used to dock with the steel column, providing stable support for the entire grouting hopper 1 and ensuring that the device does not shake or become unstable during grouting. Two blocking rods 205 are fixedly connected to the middle of the two fixed support legs 204. The blocking rods 205 are used to cooperate with the subsequent mechanism to adjust the angle of the entire grouting hopper 1. A drive assembly is fixedly connected to the bottom of the grouting hopper 1.
[0028] The drive assembly includes two fixed piles 206, the tops of which are fixedly connected to the bottom of the grouting hopper 1, providing stable support points for the drive assembly. A rotating column 207 is rotatably connected inside the two fixed piles 206. One end of the rotating column 207 is threadedly connected to a nut 208. Rotation of the nut 208 drives the rotating column 207 to rotate, and the rotating column 207 transmits the rotational power of the nut 208 to subsequent structures. A tie rod 209 is fixedly connected to the outer wall of the rotating column 207, providing a stable sliding path for subsequent structures. A butterfly nut 210 is threadedly connected to the outer wall of the tie rod 209, and the outer wall of the butterfly nut 210 contacts the outer walls of the two barrier rods 205. After the two fixed support legs 204 are aligned with the steel column, rotate the second nut 208. At this time, since the tie rod 209 is inserted between the two blocking rods 205, rotating the butterfly nut 210 will convert the rotation of the butterfly nut 210 on the tie rod into linear motion along the tie rod axis. This movement of the butterfly nut 210 adjusts the grouting angle of the grouting hopper 1. This allows the grouting hopper 1 to be precisely adapted to the actual angle of the grouting opening of the steel column, and also fixes the two fixed support legs 204, making the connection between the grouting hopper 1 and the steel column more stable.
[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6The adjusting mechanism 3 includes a support plate 301, the bottom of which is detachably connected to the bottom of the grouting hopper 1. This detachable connection facilitates the installation, disassembly, and subsequent maintenance of the device. Two screws 302 are threadedly connected to the top of the support plate 301, and the bottom of these screws 302 is threadedly connected to the top of the grouting hopper 1, thus securing the support plate 301 firmly to the grouting hopper 1. An outer tube 303 is rotatably connected to the middle of the support plate 301. The outer tube 303 acts as a transmission mechanism, causing the subsequent structure to rotate. A drive nut 304 is threadedly connected to the outer wall of one end of the outer tube 303, and rotating the drive nut 304 causes the outer tube 303 to rotate. A rotating plate 305 is fixedly connected to the outer wall of the other end of the outer tube 303. The bottom outer wall of the rotating plate 305 is slidably connected to the top inner wall of the grouting hopper 1. The rotating plate 305 is used to transmit power to the outer tube 303 and, through contact with the bottom of the grouting hopper 1, ensures that there is no gap between the entire adjusting mechanism 3 and the grouting hopper 1. An inner tube 306 is rotatably connected to the inner wall of the outer tube 303, and the inner tube 306 serves as a transmission mechanism. A drive thread 2 is threaded to the outer wall of one end of the inner tube 306, and a rotating plate 308 is fixedly connected to the other end of the inner tube 306. The bottom outer wall of the rotating plate 308 is slidably connected to the top inner wall of the grouting hopper 1. By rotating the drive nut 307, the inner tube 306 is driven to rotate, thereby driving the rotating plate 308 to rotate synchronously.
[0030] The limiting component includes two partitions 309, whose outer walls are fixedly connected to the outer walls of the other ends of rotating plate 305 and rotating plate 308, respectively. The bottom outer walls of the two partitions 309 are in contact with the top inner wall of the grouting hopper 1. The partitions 309 serve to divide and guide the grouting material, allowing it to flow along a pre-defined path and within a defined area. Limiting rings 310 are fixedly connected to the outer walls of the partitions 309. The outer walls of the two limiting rings 310 are in contact with the top outer wall of the grouting hopper 1. The limiting rings 310 effectively constrain the flow range of the grouting material, ensuring that all the grouting material enters between the two partitions 309 for grouting operations, preventing overflow or flow into other unnecessary areas, and guaranteeing the accuracy and efficiency of the grouting operation.
[0031] Working principle: In use, the grouting hopper 1 is inserted into the grouting port of the steel column. The nut 202 is rotated, causing the connecting stud 201 to rotate, which in turn causes the fixed cylinder 203 to rotate. This causes the two fixed support legs 204 to rotate around the connecting stud 201 until the two fixed support legs 204 are aligned with the steel column. Then, the nut 208 is rotated. At this point, since the tie rod 209 is inserted between the two blocking rods 205, the butterfly nut 210 is rotated. The rotation of the butterfly nut 210 on the tie rod is converted into linear motion along the tie rod axis. The butterfly nut 210 then presses against the two blocking rods 205, thereby adjusting the grouting angle of the grouting hopper 1 and fixing the two fixed support legs 204, thus ensuring a stable connection between the grouting hopper 1 and the steel column.
[0032] Next, based on the size of the grouting opening, rotate the drive nut 304. The rotation of the drive nut 304 causes the outer tube 303 to rotate, which in turn causes the rotating plate 305 and the corresponding partition 309 to rotate, thereby adjusting the position of the partition 309 corresponding to the rotating plate 305. Then, by rotating the drive nut 307, the rotation of the drive nut 307 causes the inner tube 306 to rotate, which in turn causes the rotating plate 308 and the corresponding partition 309 to rotate synchronously. This allows the distance between the two partitions 309 to be adjusted according to the size of the grouting opening, so that the outlet corresponds to the grouting opening. At the same time, the limiting ring 310 ensures that all the grouting material enters between the two partitions 309 for the grouting operation.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
