Description

Technical Field

[0001] This utility model belongs to the field of building technology, specifically relating to a concrete pouring tool for secondary structural columns. Background Technology

[0002] "Secondary structural column concrete pouring tool" refers to a small, mechanized device specifically designed for pouring concrete for secondary structures (such as structural columns, ring beams, and window sill copings within frame infill walls). It typically consists of a hopper, pumping mechanism, support frame, and discharge pipe. It can vertically or horizontally transport on-site mixed or pre-mixed fine aggregate concrete into narrow formwork, replacing the traditional manual feeding method using shovels and funnels. This offers advantages such as labor savings, dust reduction, and improved compaction. Because secondary structural columns have small cross-sections, dense reinforcement, and varying heights depending on the floor level, this tool must balance portability with conveying accuracy. Therefore, its dimensions, discharge port location, and pipeline layout are all designed with "mobility and detachability" as the core principles.

[0003] However, existing tools have obvious shortcomings when dealing with continuous pouring from multiple directions and angles: First, the machine relies on bottom casters for movement, and has a large turning radius in spaces where reinforcement has been tied or walls have been built. It is easy for the edges of the formwork and scaffolding to block it, so after "one point is poured", the whole machine needs to be pushed and pulled and repositioned, which is time-consuming, laborious and has a high risk of damage. Second, the discharge pipes are mostly rigid steel pipes or plastic hoses with fixed lengths and non-adjustable angles. They can only be inserted into the top of the structural column in a near-vertical position. When encountering structural columns with varying heights, cantilevered window sills or irregular components, either the pipe length is insufficient and additional hoses need to be connected, causing sealing leakage, or the angle is too large, causing segregation and pipe blockage. Moreover, the connection process requires stopping the machine and manual climbing, making it difficult to guarantee efficiency and quality. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a concrete pouring tool for secondary structural columns, which facilitates the adjustment of the pouring position and the angle and length of the pouring pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete pouring tool for secondary structural columns, comprising a base plate, a universal wheel with brake is provided at the lower corner of the base plate, a push rod is provided on the upper side of the base plate, a connecting rod is provided at the upper end of the push rod, a control panel is provided at the center of the connecting rod, a rotating mechanism is provided at the center of the upper end of the base plate, a grouting pump is provided at the upper end of the rotating mechanism, a pouring pipe adjustment mechanism is provided on the side of the grouting pump, and a tank is provided at the upper end of the grouting pump; The pouring pipe adjustment mechanism includes a grout discharge pipe, a grout discharge pipe is provided on the side of the grout pump, a telescopic bend is provided at the other end of the grout discharge pipe, a pouring pipe head is provided at the other end of the telescopic bend, a U-shaped plate is provided on the upper side of the rotating mechanism, and an angle adjustment component is provided on the side of the U-shaped plate.

[0006] Preferably, the pouring pipe adjustment mechanism further includes a limiting ring, a limiting ring is provided on one end surface of the pouring pipe head, a telescopic pipe is provided on the other end of the pouring pipe head, a pouring pipe end is provided on the other end of the telescopic pipe, another set of limiting rings is provided on one end surface of the pouring pipe end, and an electric push rod is connected between the two sets of limiting rings.

[0007] Preferably, the angle adjustment component includes a mounting box, with the mounting box provided on the outer side of the U-shaped plate, a motor provided at the lower end of the inner wall of the U-shaped plate, a drive shaft provided at the output end of the motor, and a small gear provided at the other end of the drive shaft inside the mounting box. A large gear is meshed with the side of the small gear, and a rotating shaft is provided on the side of the large gear and connected to the beginning end of the pouring pipe.

[0008] Preferably, the other end of the rotating shaft is rotatably connected to the U-shaped plate via a bearing.

[0009] Preferably, the rotating mechanism includes a fixed box, with the fixed box located at the upper center of the base plate, and a protective shell located on the lower side of the base plate. The protective shell is fixedly connected to the base plate by bolts. A second motor is installed inside the protective shell, and a second drive shaft is installed at the output end of the second motor. A drive gear is installed at the upper end of the second drive shaft inside the fixed box, and a driven gear is meshed with the side of the drive gear. A second rotating shaft is installed through the inside of the driven gear, and a rotating plate is fixed at the upper end of the second rotating shaft. The lower end of the second rotating shaft is rotatably connected to the fixed box by a bearing. A guide assembly is installed on the upper side of the fixed box.

[0010] Preferably, the guide assembly includes a pulley structure, with a pulley structure provided on the upper side of the fixed box and an annular slide rail corresponding to the pulley structure provided on the lower side of the rotating plate.

[0011] Preferably, the pulley structure includes a fixed rod, a fixed rod is provided on the upper side of the fixed box, a rotating block is provided on the upper end of the fixed rod, a rotating seat is provided on the upper surface of the rotating block, and a rotating groove corresponding to the rotating block is opened inside the rotating seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model incorporates a pouring pipe adjustment mechanism. The length of the pipe is adjusted by steplessly pushing and pulling the telescopic pipe via an electric push rod. Simultaneously, a motor drives a gear set to tilt the beginning of the pouring pipe to adjust its angle. The discharge port is precisely aligned with the injection port of the structural column, effectively preventing grout leakage and segregation. This eliminates the need for manual climbing to connect the pipe, significantly improving efficiency and providing good compatibility with different floor heights and irregularly shaped components.

[0013] 2. This utility model incorporates a rotating mechanism. A motor, after being reduced in speed by a gear set, drives the rotating plate to rotate horizontally. This results in a small turning radius, allowing for the coverage of multiple adjacent structural columns in a narrow space with a single positioning operation. This enables "one-time material loading and continuous pouring at multiple points," reducing overall machine displacement. Simultaneously, the cooperation between the pulley structure and the annular slide rail counteracts the cantilever overturning moment, ensuring smooth operation and high precision in power-off self-locking, thereby significantly reducing labor intensity.

[0015] 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.

[0016] Example 1: Please see Figure 1-6The present invention provides the following technical solution: a concrete pouring tool for secondary structure columns, including a base plate 1, a universal wheel 2 with brake is provided at the lower corner of the base plate 1, a push rod 9 is provided on the upper side of the base plate 1, a connecting rod 8 is provided at the upper side of the push rod 9, a control panel 7 is provided at the center of the connecting rod 8, a rotating mechanism 3 is provided at the center of the upper end of the base plate 1, a grouting pump 4 is provided at the upper end of the rotating mechanism 3, a pouring pipe adjustment mechanism 5 is provided on the side of the grouting pump 4, and a tank 6 is provided at the upper end of the grouting pump 4; The pouring pipe adjustment mechanism 5 includes a grout discharge pipe 58. The grout discharge pipe 58 is provided on the side of the grout pump 4. The other end of the grout discharge pipe 58 is provided with a telescopic bend 57. The other end of the telescopic bend 57 is provided with the pouring pipe head end 56. The upper side of the rotating mechanism 3 is provided with a U-shaped plate 51. The side of the U-shaped plate 51 is provided with an angle adjustment component 59.

[0017] Specifically, the pouring pipe adjustment mechanism 5 also includes a limiting ring 55. A limiting ring 55 is provided on one end surface of the pouring pipe head 56, and a telescopic pipe 54 is provided on the other end of the pouring pipe head 56. A pouring pipe end 53 is provided on the other end of the telescopic pipe 54, and another set of limiting rings 55 is provided on one end surface of the pouring pipe end 53. An electric push rod 52 is connected between the two sets of limiting rings 55. The electric push rod 52 is a servo electric cylinder with an IP67 protection rating. Its push rod surface is hard chrome plated, and a corrugated dust cover is added externally to prevent cement slurry intrusion. A double-layer rubber sealing ring is provided at the junction of the motor 596 and the mounting box 592 to ensure long-term reliable operation of the gear set in harsh environments. By adopting the above technical solution, the electric push rod 52 can drive the telescopic tube 54 to extend or shorten synchronously when it extends or retracts, so as to realize stepless adjustment of the length of the pouring pipe, adapt to the structural column templates with different spacing, avoid manual connection, improve the efficiency of continuous operation, and the limiting ring 55 serves as both the push rod hinge point and prevents the telescopic tube 54 from slipping excessively, thus forming a mechanical limit.

[0018] Specifically, the inner walls of both the expansion joint 54 and the expansion bend 57 are lined with an ultra-high molecular weight polyethylene wear-resistant layer, with a smooth surface and a friction coefficient of less than 0.15, effectively preventing concrete adhesion. The bending radius of the expansion bend 57 is not less than 5 times the pipe diameter to avoid dead zones in grout flow. Furthermore, a high-frequency micro-vibrator is installed at the connection between the pouring pipe end 56 and the expansion bend 57, automatically activating during pumping intervals to prevent grout deposition and blockage. By adopting the above technical solutions, optimizing the pipe inner wall material and bending radius, and combining them with a high-frequency micro-vibration anti-blockage mechanism, smooth concrete flow is ensured during adjustment, fundamentally preventing segregation and pipe blockage.

[0019] Specifically, the angle adjustment component 59 includes a mounting box 592. The mounting box 592 is located on the outer side of the U-shaped plate 51. A motor 596 is located at the lower end of the inner wall of the U-shaped plate 51. A drive shaft 595 is located at the output end of the motor 596. A small gear 594 is located inside the mounting box 592 at the other end of the drive shaft 595. A large gear 593 is meshed with the side of the small gear 594. A rotating shaft 591 is located on the side of the large gear 593 and is connected to the first end 56 of the pouring pipe. By adopting the above technical solution, the motor 596 drives the large gear 593 through the small gear 594 to reduce speed and increase torque, thereby driving the rotating shaft 591 and the first end 56 of the pouring pipe to pitch within the range of -30° to 90°, so as to achieve precise alignment of the discharge port with the pouring port of the structural column. The gear pair is enclosed in the mounting box 592, which can prevent cement slurry from entering and extend the service life.

[0020] Specifically, the other end of the rotating shaft 591 is rotatably connected to the U-shaped plate 51 through a bearing. By adopting the above technical solution, the bearing is a double-sided sealed deep groove ball bearing, which can withstand radial loads and slight axial impacts, ensuring that the angle adjustment process is smooth and without jamming, and at the same time facilitating later maintenance and replacement.

[0021] Specifically, the control panel 7 integrates a PLC controller, which receives signals from the absolute encoder installed on the rotating shaft 591 to monitor the pitch angle of the pouring pipe in real time; the electric push rod 52 has a built-in stroke sensor to provide feedback on the length of the telescopic pipe. The system is set with interlock logic: when the rotating mechanism 3 is activated, it automatically limits the maximum telescopic length and pitch angle of the pouring pipe adjusting mechanism 5 to prevent mechanical interference. In addition, the control panel 7 has an "intelligent alignment" mode. After the user inputs the height of the structural column and the horizontal distance, the system automatically calculates and executes the optimal combination of length and angle to achieve one-click precise alignment.

[0022] In this embodiment, the machine is pushed to the vicinity of the structural column to be poured using the push rod 9. The brake plate of the universal wheel 2 with brake is stepped on for positioning. Pre-mixed fine stone concrete is poured into the tank 6. The grout pump 4 is started. The grout flows through the discharge pipe 58 and the telescopic bend 57 to the first end 56 of the pouring pipe. According to the height of the structural column and the horizontal distance, the "Length" button on the control panel 7 is operated to extend and retract the electric push rod 52, so that the end 53 of the pouring pipe extends into the template injection port. The "Angle + / -" button is operated, and the motor 596 runs, tilting the pouring pipe to the optimal angle to avoid grout splashing and segregation. The length and angle can be adjusted in real time during the pouring process to achieve layered, continuous, and dead-zone-free pouring. After the pouring is completed, the electric push rod 52 retracts, the motor 596 resets, the grout pump 4 is turned off, and the brake is released to move the machine to the next location.

[0023] Example 2: Based on Embodiment 1, this embodiment further discloses the specific structure of the rotating mechanism 3: it includes a fixed box 38, which is located at the upper center of the base plate 1, and a protective shell 34 is located on the lower side of the base plate 1. The protective shell 34 and the fixed box 38 are connected by a silicone sealing strip, achieving an overall protection level of IP54, effectively preventing dust and splashing water from affecting the second motor 33 and the gear transmission system. The protective shell 34 is fixedly connected to the base plate 1 by bolts 35. The second motor 33 is installed inside the protective shell 34. The second motor 33 is a servo motor with an electromagnetic brake, which automatically locks the second rotating shaft 36 after power failure, ensuring that the rotation positioning accuracy is within ±1°. The output end of motor 2 33 is equipped with drive shaft 2 32. The upper end of drive shaft 2 32 is located inside the fixed box 38 and is equipped with drive gear 31. Drive gear 37 is meshed with the side of drive gear 31. Rotating shaft 2 36 is installed through the inside of driven gear 37. Rotating plate 310 is fixed to the upper end of rotating shaft 2 36. The lower end of rotating shaft 2 36 is rotatably connected to fixed box 38 through bearing. Guide component 39 is provided on the upper side of fixed box 38. By adopting the above technical solution, motor 2 33 adopts a low-speed, high-torque gear reduction motor. After two-stage reduction by drive gear 31 and driven gear 37, it drives rotating plate 310 and all components above it to rotate 360° horizontally. It can cover multiple adjacent structural columns in one positioning in a narrow room without the need to move the whole machine. Adjustable counterweights can be symmetrically arranged on rotating plate 310. The position of the counterweights can be adjusted in real time according to the amount of concrete in the tank to ensure the stability of the center of gravity during rotation.

[0024] Specifically, the guide assembly 39 includes a pulley structure 391. The pulley structure 391 is located on the upper side of the fixed box 38, and an annular slide rail 392 corresponding to the pulley structure 391 is located on the lower side of the rotating plate 310. The surface of the annular slide rail 392 is hardened to a hardness ≥ HRC55. The rotating seat 3911 of the pulley structure 391 uses an inlaid bronze bushing filled with lithium-based grease, with a pressure resistance ≥ 5 MPa. By adopting the above technical solution, the pulley structure 391 rolls along the annular slide rail 392, forming a composite guide of "upper rotation and lower support," which can counteract the overturning moment generated by the cantilever of the casting pipe, ensuring smooth rotation without abnormal noise. The slide rail has a "V" shaped cross-section, and the outer edge of the pulley matches it, providing an automatic centering function.

[0025] Specifically, the pulley structure 391 includes a fixed rod 3914. The fixed rod 3914 is provided on the upper side of the fixed box 38. A rotating block 3913 is provided on the upper end of the fixed rod 3914. A rotating seat 3911 is provided on the upper surface of the rotating block 3913. A rotating groove 3912 corresponding to the rotating block 3913 is opened inside the rotating seat 3911. By adopting the above technical solution, lithium-based grease is filled between the rotating block 3913 and the rotating seat 3911, which can work for a long time in an environment from -20℃ to 60℃. The fixed rod 3914 is made of 45 steel with heat treatment and nickel plating on the surface, which has strong corrosion resistance. The overall pulley structure 391 is a modular design, which can be replaced as a whole by removing the bolts, and the maintenance time is less than 5 minutes.

[0026] In this embodiment, when it is necessary to switch to the next structural column in the same room, there is no need to move the base plate 1. Simply use the "left turn / right turn" button on the control panel 7 to start the motor 33. The rotating plate 310 drives the pouring pipe adjustment mechanism 5 to rotate to the new position. During the rotation, the guide component 39 supports the rotating plate 310 in real time to prevent shaking caused by the eccentricity of the slurry in the tank 6. After reaching the target angle, the motor 33 is de-energized and self-locked. The positioning accuracy is ±1°, and the pouring action of embodiment 1 can be repeated. If a long-distance transfer is required, the brake wheel is released, and the push rod 9 is pushed and pulled as a whole. The rotating mechanism 3 and the pouring pipe adjustment mechanism 5 maintain their current posture. After reaching the next pouring area, the positioning, rotation, and pouring are repeated to achieve "one-time feeding and multi-point continuous pouring", which improves efficiency by more than 30%.

[0027] The working principle and usage process of this utility model are as follows: First, push the whole machine to the vicinity of the structural column to be poured by push rod 9, step on the brake plate of the universal wheel 2 with brake to position it, pour the pre-mixed fine stone concrete into the tank 6, start the grout pump 4, and the grout reaches the first end 56 of the pouring pipe through the grout discharge pipe 58 and the telescopic bend 57. According to the height of the structural column and the horizontal distance, operate the "length" button on the control panel 7 to extend and retract the electric push rod 52 so that the end 53 of the pouring pipe extends into the template injection port. Operate the "angle + / -" button, the motor 596 runs, and the pouring pipe tilts to the optimal tilt angle to avoid grout splashing and segregation. The length and angle can be adjusted in real time during the pouring process to achieve layered, continuous, and dead-zone-free pouring. After the pouring is completed, the electric push rod 52 retracts, the motor 596 resets, the grout pump 4 is turned off, and the brake is released to move to another location.

[0028] When it is necessary to switch to the next structural column in the same room, there is no need to move the base plate 1. Simply use the "left turn / right turn" button on the control panel 7 to start the motor 33. The rotating plate 310 drives the pouring pipe adjustment mechanism 5 to rotate to the new position. During the rotation, the guide component 39 supports the rotating plate 310 in real time to prevent shaking caused by the eccentricity of the slurry in the tank 6. After reaching the target angle, the motor 33 is de-energized and self-locked. The positioning accuracy is ±1°, and the pouring action of Example 1 can be repeated. If a long-distance transfer is required, release the brake wheel and push the push rod 9 to push and pull as a whole. The rotating mechanism 3 and the pouring pipe adjustment mechanism 5 maintain their current posture. After reaching the next pouring area, reposition, rotate, and pour again to achieve "one-time feeding and multi-point continuous pouring", which improves efficiency by more than 30%.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
