Description

Technical Field

[0001] This invention relates to the field of beam surface construction technology, specifically an integrated beam surface vibration leveling and smoothing device and its working method. Background Technology

[0002] Vibration, leveling, and troweling are indispensable steps in concrete construction, and their quality directly affects the overall quality and durability of the beam surface. Vibration removes air bubbles and voids from the concrete, making it more compact and increasing its density. This results in better strength and durability, enabling it to withstand greater loads and deformations. Leveling ensures the smoothness of the beam surface, reducing bumps and noise during driving and improving comfort and safety. Troweling makes the beam surface smoother and more aesthetically pleasing.

[0003] In bridge engineering projects involving long spans and heavy traffic, vibration compaction, leveling, and troweling are carried out using various equipment such as vibratory compactors and leveling machines, in a predetermined construction sequence, to complete these three construction operations. However, the combined use of multiple pieces of equipment also requires multiple disassembly, retrieval, and installation operations during deployment and installation, consuming manpower and extending the construction time. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated beam surface vibration leveling and troweling device and its working method, so as to solve the problems mentioned in the background art that the prior art requires the use of multiple devices, multiple deployments and installations consume manpower and prolong construction time.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated beam surface vibratory leveling and troweling device includes a truss. A traveling mechanism for driving the truss to move along the beam formwork is provided at the bottom of the truss. A leveling mechanism and a troweling mechanism are fixedly installed on both sides of the inner wall of the truss. The leveling mechanism includes a leveling mounting frame, and a leveling roller is rotatably mounted on the inner wall of the leveling mounting frame. The troweling mechanism includes a troweling frame, and an adjusting motor is fixedly installed on the inner wall of the troweling frame. An adjusting bracket is fixedly connected to the output end of the adjusting motor, and a troweling plate is fixedly connected to the middle of the adjusting bracket. A vibratory worktable is slidably mounted on the top of the leveling mounting frame, and a vibrating rod is engaged with the middle of the vibratory worktable.

[0007] As a further embodiment of the present invention: a leveling motor is fixedly installed at one end of the leveling mounting frame, an adapter plate is fixedly connected to the output end of the leveling motor, one side of the adapter plate is fixedly connected to the end edge of the leveling roller, a central support rod is rotatably connected to the middle of the leveling roller, and one end of the central support rod is fixedly connected to the leveling mounting frame.

[0008] As a further aspect of the present invention: the interior of the leveling roller is provided with a plurality of vibration chambers, the inner wall of the vibration chamber is fixedly connected with a vibration spring, the top of the vibration spring is fixedly connected with a contact plate, and the middle of the central support rod is fixedly connected with a plurality of pushing blocks, the plurality of pushing blocks being located in the plurality of vibration chambers respectively.

[0009] As a further aspect of the present invention: a plurality of support components are provided on one side of the leveling roller, the support components include a support frame, an auxiliary rotating roller is rotatably mounted on the inner wall of the support frame, a positioning frame is fixedly connected to one end of the support frame, a positioning rod is fixedly connected to one end of the positioning frame, a detection ring is sleeved in the middle of the positioning rod, and a pressure sensor is fixedly mounted on the inner wall of the detection ring.

[0010] As a further aspect of the present invention: a secondary leveling assembly is provided between the leveling mechanism and the polishing mechanism. The secondary leveling assembly includes a shifting guide rail, a shifting seat is slidably connected to the inner wall of the shifting guide rail, a roller frame is provided below the shifting seat, a secondary roller is rotatably mounted on the inner wall of the roller frame, and an attitude adjustment cylinder is fixedly installed at both ends of the bottom of the shifting seat. The output ends of the two attitude adjustment cylinders are rotatably connected to the two ends of the roller frame, respectively.

[0011] As a further aspect of the present invention: a linear motor is fixedly installed on one side of the adjustment frame, and a pressing frame is fixedly connected to the output end of the linear motor. Several contact rollers are rotatably installed on the inner wall of the pressing frame.

[0012] As a further aspect of the present invention: the walking mechanism includes an adjusting hydraulic cylinder, the output end of which is fixedly connected to a limit frame, and a walking wheel is rotatably mounted on the inner wall of the limit frame.

[0013] As a further aspect of the present invention: equipment frames are fixedly connected to both sides of the vibrating workbench, and a dust cover is rotatably connected to the top of the equipment frame.

[0014] A method for operating an integrated beam surface vibratory leveling and troweling device includes the following steps:

[0015] Step 1: The truss is moved by the traveling mechanism, and during the movement, the worker removes the vibrator and inserts it into the concrete to be vibrated;

[0016] Step 2: Start the vibrator to vibrate the concrete. After vibration is complete, the truss moves again, and workers retrieve the vibrator during the movement.

[0017] Step 3: Move the truss using the walking mechanism and start the leveling motor to drive the leveling roller to rotate, leveling the concrete surface during the truss movement.

[0018] Step 4: Observe the state of the concrete surface after leveling by the leveling roller. If there are still uneven areas, use the shifting guide rail to drive the secondary roller to move above the position and perform secondary leveling of the concrete surface.

[0019] Step 5: After the leveling operation is completed, the adjusting motor drives the trowel to rotate, so that it contacts the concrete surface and smooths the concrete surface.

[0020] Compared with the prior art, the beneficial effects of the present invention are: by integrating the leveling mechanism, the troweling mechanism and the vibrator into one unit, the leveling, troweling and vibration operations of the beam surface can be completed by one device, eliminating the need for repeated disassembly and installation operations between different devices, thereby effectively saving construction time and reducing manpower consumption.

[0021] The leveling mechanism of the present invention uses the rotation of the leveling roller to level the beam surface, and drives each push block to rotate by setting a central support rod. The push blocks compress and release the contact plate, and the vibration generated in this process drives the leveling roller to vibrate as a whole, which effectively improves the leveling effect of the leveling roller on the beam surface.

[0022] This invention provides support components, which use one side of the auxiliary roller to press against the leveling roller to support and correct the leveling roller. When the leveling roller deforms, the pressure on the auxiliary roller at the deformed part will change, which will cause a change in the reading of the pressure sensor. This enables the detection of the leveling roller's condition and ensures that the leveling roller can be leveled in a relatively straight state.

[0023] This invention uses a two-stage leveling assembly and a shifting guide rail to adjust the position of the two-stage rotating roller so that it corresponds to the position to be leveled. The rotation of the two-stage rotating roller is used to perform a secondary roll pressing leveling operation to eliminate the above-mentioned ripples. In addition, both ends of the bottom of the shifting seat are fixedly installed with posture adjustment cylinders. The output ends of the two posture adjustment cylinders are rotatably connected to the two ends of the rotating roller frame, thereby realizing the adjustment of the height and posture of the two-stage rotating roller to meet the leveling needs of beam surfaces with different degrees of undulation.

[0024] The troweling mechanism of the present invention drives the rotation of the troweling plate by setting an adjusting motor and other structures, so that the troweling plate contacts the beam surface to realize the troweling operation. The adjusting motor is used to adjust the angle of the troweling plate to meet the requirements of the troweling plate's opening and closing. The pressing frame is set to provide auxiliary support for the troweling plate to ensure its shape stability and to ensure stable contact between the center of the troweling plate and the beam surface, thereby improving the uniformity of the troweling.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 In this embodiment of the invention, an integrated beam surface vibration leveling and finishing device includes a truss 2. The bottom of the truss 2 is provided with a traveling mechanism for driving the truss 2 to move along the beam mold 1. (See also...) Figure 8 The traveling mechanism includes an adjusting hydraulic cylinder 202, the output end of which is fixedly connected to a limit frame 203. A traveling wheel 201 is rotatably mounted on the inner wall of the limit frame 203. The outer wall of the traveling wheel 201 has anti-slip grooves. Bearing plates are provided on both sides of the beam formwork 1, and mating grooves are provided on both bearing plates. These grooves mesh with the anti-slip gears to improve the stability of the traveling wheel 201 during travel. Furthermore, sensors can be installed on the traveling mechanisms on both sides to detect the rotation distance of the traveling wheel 201, ensuring that the movement distance on both sides of the truss 2 remains consistent. This prevents the truss 2 from tilting during construction and operation, thus ensuring the consistency and uniformity of the overall beam surface leveling and smoothing operation.

[0036] Please see Figure 2 A leveling mechanism 3 and a troweling mechanism 5 are fixedly installed on both sides of the inner wall of the truss 2, and a vibrating workbench 7 is slidably installed on the top of the leveling mounting frame 309. By integrating the leveling mechanism 3, the troweling mechanism 5, and the vibrating rod 701 into a single unit, the leveling, troweling, and vibration operations on the beam surface can be completed by a single device, eliminating the need for repeated disassembly and installation of different devices, thereby effectively saving construction time and reducing labor consumption.

[0037] The leveling mechanism 3 includes a leveling mounting frame 309. A leveling pressure roller 301 is rotatably mounted on the inner wall of the leveling mounting frame 309. The leveling pressure roller 301 is used to level the beam surface by rotating. The distance between the leveling pressure roller 301 and the beam surface can be adjusted by adjusting the hydraulic cylinder 202. That is, by adjusting the hydraulic cylinder 202 to push out the traveling wheel 201, the truss 2 is lifted as a whole, thereby adjusting the height of the leveling pressure roller 301.

[0038] Please see Figure 4To drive the leveling roller 301, a leveling motor is fixedly mounted on one end of the leveling mounting frame 309. An adapter plate 306 is fixedly connected to the output end of the leveling motor. One side of the adapter plate 306 is fixedly connected to the edge of the leveling roller 301. During leveling operations, the outer wall of the leveling roller 301 directly contacts the beam surface and experiences resistance. Conventional driving methods involve rotating a transmission rod located at the center of the leveling roller 301. However, the distance between the transmission rod and the edge of the leveling roller 301 is relatively large, resulting in a high rotational torque and poor transmission efficiency. This application addresses this by using the adapter plate 306 to directly apply the driving force of the leveling motor to the edge of the leveling roller 301, making the drive of the leveling roller 301 more effortless. In practical use, a gear set can be directly installed between the output end of the leveling motor and the adapter plate 306 to adjust the transmission coefficient, allowing the leveling roller 301 to rotate stably at a low speed.

[0039] Please see Figures 4-5 To install and support the leveling roller 301 as a whole, a central support rod 302 is rotatably connected to the middle of the leveling roller 301. The end of the central support rod 302 away from the leveling motor is fixedly connected to the leveling mounting frame 309, and the other end of the central support rod 302 is rotatably connected to the middle of the adapter frame 307.

[0040] To improve the leveling effect of the leveling roller 301, the leveling roller 301 has several vibration chambers 308 inside. Vibration springs 305 are fixedly connected to the inner walls of the vibration chambers 308. Contact plates 304 are fixedly connected to the top of the vibration springs 305. Several pushing blocks 303 are fixedly connected to the middle of the central support rod 302. The pushing blocks 303 are located in the vibration chambers 308 respectively and maintain contact with at least one contact plate 304 during rotation. In this embodiment, the pushing blocks 303 are set in the shape of regular triangular prisms, and there are two contact plates 304, which are symmetrically arranged. By setting the central support rod 302 to drive each pushing block 303 to rotate, the compression and release of the contact plates 304 by the pushing blocks 303 are used, and the vibration generated in this process drives the leveling roller 301 to vibrate as a whole, thereby effectively improving the leveling effect of the leveling roller 301 on the beam surface.

[0041] Please see Figure 2Because the leveling roller is relatively long, to prevent deformation during prolonged use and thus affecting the leveling operation, this application provides several support components 6 on one side of the leveling roller 301. Each support component 6 includes a support frame 601, with an auxiliary roller 603 rotatably mounted on the inner wall of the support frame 601. One side of the auxiliary roller 603 is in close contact with the leveling roller 301, thereby supporting and correcting the leveling roller. When the leveling roller 301 undergoes significant deformation, it will be unable to rotate due to the obstruction of the auxiliary roller 603, thus alerting the operator to perform maintenance or replacement. Mounting plates 602 are fixedly connected to both ends of the support frame 601, and the middle of the mounting plates 602 is fixedly connected to the leveling mounting frame 309 via mounting bolts.

[0042] Please see Figure 3 To detect the deformation degree of the leveling roller 301 and prevent the leveling roller 301 from failing to rotate, this application has a positioning frame 604 fixedly connected to one end of the support frame 601. A positioning rod is fixedly connected to one end of the positioning frame 604. A detection ring 605 is sleeved in the middle of the positioning rod. A pressure sensor 606 is fixedly installed on the inner wall of the detection ring 605. When the leveling roller 301 deforms, the pressure on the auxiliary roller 603 at the deformed part will change, which will cause the position of the positioning rod to change, and cause the reading of the pressure sensor 606 to change. The operator can judge the deformation state of the leveling roller 301 by the change in the reading of the pressure sensor 606, thereby realizing the detection.

[0043] Please see Figure 2 and Figure 6 Because only the leveling roller 301 is used for leveling, uneven pressure between the middle and the ends, or the influence of the length of the leveling roller 301 itself, makes it easy for concrete ripples or undulations to occur on the beam surface located at the outer edge or middle of its end after leveling and pressing, resulting in an uneven beam surface. To optimize this situation, this application provides a secondary leveling component 4 between the leveling mechanism 3 and the smoothing mechanism 5. The secondary leveling component 4 includes a shifting guide rail 401, a shifting seat 404 slidably connected to the inner wall of the shifting guide rail 401, a rotating roller frame 402 below the shifting seat 404, and a secondary rotating roller 403 rotatably mounted on the inner wall of the rotating roller frame 402. In use, the position of the secondary rotating roller 403 is adjusted by the shifting guide rail 401 to correspond to the position to be leveled; the presence of the secondary rotating roller 403 is used to perform a secondary rolling and leveling operation to eliminate the aforementioned ripples and undulations. To achieve the need for leveling beam surfaces with different degrees of undulation, both ends of the bottom of the shift seat 404 of this application are fixedly installed with attitude adjustment cylinders 405. The output ends of the two attitude adjustment cylinders 405 are rotatably connected to both ends of the roller frame 402, thereby realizing the adjustment of the height and attitude of the secondary roller 403.

[0044] Please see Figure 1 and Figure 7 The troweling mechanism 5 includes a troweling frame 501, an adjusting motor is fixedly installed on the inner wall of the troweling frame 501, an adjusting frame 502 is fixedly connected to the output end of the adjusting motor, and a troweling plate 503 is fixedly connected to the middle of the adjusting frame 502. By setting the adjusting motor and other structures, the troweling plate 503 is driven to rotate, so that the troweling plate 503 contacts the beam surface to realize the troweling operation. The adjusting motor is used to adjust the angle of the troweling plate 503 to meet the requirements for the extension and retraction of the troweling plate 503.

[0045] Because the trowel 503 is relatively long, a linear motor 504 is fixedly installed on one side of the adjusting frame 502 to ensure stable contact between its middle position and the beam surface. The output end of the linear motor 504 is fixedly connected to a pressing frame 505. Several contact rollers 506 are rotatably installed on the inner wall of the pressing frame 505. The trowel 503 passes through the inner cavity of the pressing frame 505, and the pressing frame 505 provides auxiliary support for the trowel 503 to ensure its shape stability. Combined with the setting of the contact rollers 506, the resistance between the trowel 503 and the pressing frame 505 during the pushing movement is reduced.

[0046] Please see Figure 1 A vibrating rod 701 is engaged with the center of the vibrating workbench 7. Equipment frames 702 are fixedly connected to both sides of the vibrating workbench 7. A dust cover is rotatably connected to the top of the equipment frames 702. The vibrating rod 701 and the connected vibrating equipment are installed using the vibrating workbench 7 and the equipment frames 702. During vibration operation, multiple vibrating rods 701 are manually inserted into different positions on the beam surface concrete, and are retrieved after the vibration operation is completed.

[0047] In use, the invention first involves a vibration operation. The worker enters the truss 2 and stands in the workspace formed by the leveling and installation frame 309, the trowel frame 501, and the truss 2. Then, the truss 2 is moved along the length of the beam formwork 1 by rotating the walking rollers. During the movement, the worker removes multiple vibrating rods 701 and inserts them into the concrete to be vibrated. Then, the vibration equipment connected to the vibrating rods 701 is started, and the vibrating rods 701 complete the vibration operation on the concrete. After the vibration is completed, the worker climbs back onto the truss 2, and the truss 2 moves again. During the movement, the worker retrieves the vibrating rods 701.

[0048] Then, a leveling operation is performed. The truss 2 is moved along the beam formwork direction by the walking mechanism. The adjusting hydraulic cylinder 202 drives the truss 2 to move up and down as a whole, so that the bottom of the leveling roller 301 is in stable contact with the beam surface. Then, the leveling motor is started to rotate, driving the transfer plate 306 and the leveling roller 301 to rotate, and leveling the beam surface. During the rotation of the leveling roller 301, since the middle support rod 302 is fixed, it rotates relative to the outer edge of the leveling roller 301. This causes the push block 303 to contact each contact plate 304 in sequence, and completes the compression and release of the vibration spring 305 during the rotation. When the push block 303 separates from the contact plate 304 and the vibration spring 305 is released, the vibration is transmitted to the leveling roller 301, thereby driving the entire leveling roller 301 to vibrate and improving the leveling effect.

[0049] During the movement of truss 2, the state of the concrete surface after leveling by the leveling roller 301 is observed manually. If there are still uneven positions, the secondary roller 403 is moved to the top of the uneven position by the shifting guide rail 401 to perform secondary leveling of the concrete surface.

[0050] After the leveling operation is completed, the adjusting motor drives the trowel 503 to rotate, so that it contacts the concrete surface. Then, the linear motor 504 drives the pressing frame 505 to move along the trowel 503, thereby supporting and limiting the trowel 503 and avoiding the influence of deformation of the trowel 503 on the uniformity of troweling. By moving the truss 2, the trowel 503 is moved along the beam surface to achieve the troweling of the concrete surface.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
