Description

Technical Field

[0001] This utility model belongs to the technical field of vibration devices, specifically relating to an immersion vibratory device for a tunnel lining formwork trolley. Background Technology

[0002] To prevent voids, unevenness, honeycomb texture, and lack of density in the concrete during the pouring process, the concrete must be vibrated during the pouring process. Therefore, the concrete trolley must be equipped with a vibration device or have a location set up to vibrate the poured concrete.

[0003] The patent document with announcement number "CN218644297U" describes "an intelligent insertion-type vibratory compaction device for tunnel secondary lining trolleys. Addressing existing technical problems, the following solution is proposed: it includes a lining trolley template, a U-shaped frame fixed to the bottom of the template, guide rails fixed to the inner walls of both sides of the frame, a set of vibratory rods between the two sets of guide rails, and two sets of sliders symmetrically distributed along the central axis fixed to the outer side of the vibratory rods. In this invention, the insertion and withdrawal of the vibratory rods are achieved through the extension and retraction of a cylinder, resulting in low cost and high reliability. The eccentricity distance A allows the frame to be rotated via a handle to effectively avoid the reinforcing mesh. The eccentricity distance B makes the overall structure more compact, reducing the weight of the frame and thus reducing the labor intensity of the installer. Position sensors at both ends of the cylinder piston stroke transmit signals to a PLC controller, enabling automated and intelligent operation through programming."

[0004] There are two common vibration methods used on concrete trolleys: one is an attached vibrator that is fixedly distributed on the trolley template, and the other is a vibrator driven by a flexible shaft that can be manually inserted into the pouring window. The two vibration methods are used in combination on the trolley. Currently, most trolleys use an attached vibrator installed on the template and a handheld vibrator inserted through the working window on the trolley template to vibrate the concrete. The handheld vibrator is inserted into the concrete by hand through the working window for pouring, which requires workers to carry the vibrator back and forth between multiple working windows. Moreover, the handheld vibrators are all connected by flexible shafts. Sometimes, in order to improve the vibration effect, workers have to crawl into the working window to vibrate, which makes the workers' workload very high. Vibration cannot be performed on the arch and its surrounding areas where there is no working window. Utility Model Content

[0005] The purpose of this utility model is to provide an immersion vibrator for tunnel lining formwork trolleys, aiming to solve the problem that most existing trolleys use an attached vibrator installed on the formwork and a handheld vibrator inserted through a working window on the formwork to vibrate the concrete. The handheld vibrator is inserted into the concrete manually through the working window for pouring, requiring workers to carry the vibrator back and forth through multiple working windows; moreover, the handheld vibrators are all connected by flexible shafts, and sometimes, in order to improve the vibration effect, workers have to crawl into the working window to vibrate, which is very strenuous for workers; and the problem that vibration cannot be performed on the arch and its surrounding areas where there is no working window.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An immersion vibratory compaction device for a tunnel lining formwork trolley includes: Rack base; A rack guide rail, which is located on the underside of the rack base; A vibratory rod is installed inside the frame guide rail, with its extended end docking with the frame base.

[0007] As a preferred embodiment of this utility model, a mounting platform is fixedly connected to the circumferential surface of the vibrating rod, and a propulsion cylinder is connected to the upper end of the mounting platform. The extended end of the propulsion cylinder contacts the bottom of the frame base.

[0008] As a preferred embodiment of this utility model, the lower end of the frame base is fixedly connected to a hinge lug, the extended end of the propulsion cylinder is fixedly connected to a connecting block, the connecting block is located inside the hinge lug, and a pin is provided inside the hinge lug.

[0009] As a preferred embodiment of this utility model, both sides of the frame base are provided with trolley templates, and the two trolley templates are flush with the frame base.

[0010] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the lower end of the frame base, and a base pressure ring is provided inside the connecting plate.

[0011] As a preferred embodiment of this utility model, the two trolley templates are designed symmetrically.

[0012] In a preferred embodiment of this invention, the propulsion cylinder is connected to the mounting platform by bolts.

[0013] 1. In this solution, the immersion vibrator can precisely adjust the insertion depth of the vibrator rod through the control of the propulsion cylinder to ensure uniform concrete vibration. At the same time, the device is integrated on the tunnel lining formwork trolley, which improves construction efficiency and reduces manual labor intensity, making it particularly suitable for use in tunnel environments with limited space.

[0014] 2. In this solution, the insertion and withdrawal of the vibrator are achieved by the extension and retraction of the hydraulic cylinder. This method is low in cost and highly reliable. The eccentricity distance A can be effectively avoided by rotating the frame through the rotating handle. The structure reduces the weight of the frame, thereby reducing the labor intensity of the installer and user. Attached Figure Description

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.

[0018] Example 1 Please see Figures 1-2 The present invention provides the following technical solution: An immersion vibratory compaction device for a tunnel lining formwork trolley includes: Rack base 2; Rack rail 5, the rack rail 5 is located on the lower side of the rack base 2; Vibrating rod 6 is installed inside the frame guide rail 5, and its extended end is connected to the frame base 2. Vibrator guide tail seat 7 is connected to the tail end of vibrator 6; A mounting platform is fixedly connected to the circumferential surface of the vibrating rod 6, and a propulsion cylinder 8 is connected to the upper end of the mounting platform. The extended end of the propulsion cylinder 8 contacts the bottom of the frame base 2. The lower end of the frame base 2 is fixedly connected to a hinge lug 10, and the extended end of the push cylinder 8 is fixedly connected to a connecting block. The connecting block is located inside the hinge lug 10, and a pin 9 is provided inside the hinge lug 10. Both sides of the frame base 2 are provided with trolley templates 1, and the two trolley templates 1 are flush with the frame base 2; A connecting plate 3 is fixedly connected to the lower end of the frame base 2, and a base pressure ring 4 is provided inside the connecting plate 3.

[0019] In a specific embodiment of this utility model, the frame base 2 serves as the supporting structure of the device, providing stability and enabling large-scale vibration. The vibrator 6 is installed inside the bottom of the frame guide rail 5 and fixed with bolts. Its extended end is connected to the frame base 2. Vibration is applied to the concrete to achieve compaction. The vibrator guide tail seat 7 prevents the vibrator 6 from moving backward and can also be used for guidance and correction. The frame guide rail 5 guides the linear movement of the vibrator 6. The mounting platform connects to the propulsion cylinder 8, whose extended end contacts the bottom of the frame base 2. The extension and retraction of the propulsion cylinder 8 drives the vibrator 6 to move up and down along the frame guide rail 5, achieving vibration. The tamping depth is adjusted. The hinge lug 10 is used to connect the connecting block of the propulsion cylinder 8. The pin 9 can be inserted into the hinge lug 10 to fix the connecting block on the side of the extended end of the propulsion cylinder 8, ensuring the stable operation of the propulsion cylinder 8. The trolley template 1 has two pieces located on both sides of the frame base 2, flush with the frame base 2, to define the concrete pouring area. The connecting plate 3 is used to install the frame base 2 and can also be used to increase the overall stability of the device. The base pressure ring 4 enhances the load-bearing capacity and stability of the frame base 2. This device pushes out the vibrator 6 through the propulsion cylinder 8 of the hydraulic cylinder, which not only makes the propulsion and pull-out of the vibrator 6 smoother, but also makes the structure simpler, smaller in size, and lower in cost.

[0020] Please refer to the details. Figures 1-2 The two trolley templates 1 are designed symmetrically.

[0021] In this embodiment, the symmetrical design allows the device to have a larger range of use without swaying or tilting on either side, while maintaining a consistent load-bearing capacity.

[0022] Please refer to the details. Figures 1-2 The hydraulic cylinder 8 is connected to the mounting platform by bolts.

[0023] In this embodiment, the propulsion cylinder 8 and the vibrating rod 6 are fixed by bolts, which allows for easy disassembly while maintaining the stability of the structure.

[0024] The working principle and usage process of this utility model are as follows: First, the device is moved to the position where concrete pouring and vibration are required. The extension and retraction of the hydraulic cylinder 8 pushes the vibrator 6 along the frame guide rail 5. The extended end of the hydraulic cylinder 8 contacts the bottom of the frame base 2, and is connected by the pin 9 inside the hinge lug 10, allowing the vibrator 6 to flexibly adjust its position within a certain range. When the hydraulic cylinder 8 pushes the vibrator 6 forward, the vibrator 6 passes through the bottom of the frame base 2 and inserts into the concrete being poured. The vibrator guide tail seat 7 is located at the tail of the vibrator 6, ensuring the stability and linear movement of the vibrator 6. After the vibrator 6 is inserted into the concrete, its vibration function is activated to begin vibrating the concrete. Vibration eliminates air bubbles in the concrete, improving its density and strength. After vibrating one area, the retraction of the hydraulic cylinder 8 pulls the vibrator 6 out of the concrete, preparing for the next vibration operation.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
