Description

Technical Field

[0001] This utility model relates to the field of concrete shield tunnel segment technology, and in particular to a vibratory precast concrete segment surface treatment device. Background Technology

[0002] During the production of precast concrete segments, after the concrete is poured and formed, its top surface needs to be smoothed.

[0003] Currently, the industry commonly uses manual dragging of trowels by workers. However, due to the large differences in particle size of concrete, manual dragging of trowels makes it difficult to ensure a uniform and sufficient smoothing effect. This results in defects and flaws such as honeycomb and pitting easily appearing on the surface of precast concrete segments, seriously affecting the appearance quality and performance of the segments. At the same time, the manual dragging of trowels is not only labor-intensive but also extremely inefficient, making it difficult to meet the needs of large-scale industrial production. In addition, during the troweling process, excess concrete often lacks effective collection methods and can only be scattered randomly on the work site. This scattered concrete not only wastes materials but also increases the difficulty and cost of cleanup. Utility Model Content

[0032] Example 1

[0033] Reference Figures 1-6This is the first embodiment of the present invention. This embodiment provides a vibratory precast concrete segment surface treatment device. The vibratory precast concrete segment surface treatment device includes a smoothing component 200 and a collection component 300. The smoothing component 200 can overcome the problems that it is difficult to ensure a uniform and sufficient smoothing effect by manually dragging the trowel and the high labor intensity of the manual dragging trowel operation.

[0034] The main structure 100 includes a mounting plate 101, an operating table 102 fixedly connected to the top of the mounting plate 101, and a mold 103 fixedly connected to the top of the operating table 102; and...

[0035] The smoothing assembly 200 includes uprights 201 fixedly connected to the top perimeter of the mounting plate 101. A crossbar 202 is fixedly connected to the top of each upright 201. A movable frame 203 is slidably connected to the top of the crossbar 202. The crossbar 202 and the movable frame 203 are connected via a chain drive.

[0039] Example 2

[0040] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0041] Specifically, the telescopic component 206 includes a telescopic cylinder 206a fixedly connected to the bottom of the fixed plate 205, and a telescopic rod 206b slidably connected to the bottom of the telescopic cylinder 206a.

[0042] The sliding connection structure of the telescopic cylinder 206a and the telescopic rod 206b provides the scraper 211 with an adjustable telescopic function, which can flexibly adjust the height according to the shape change of the mold 103, ensuring good fit between the scraper 211 and the top of the mold 103, thereby achieving a uniform smoothing effect.

[0043] Specifically, a first spring 206c is fixedly connected to the top of the telescopic rod 206b, and the top of the first spring 206c is fixedly connected to the inner cavity of the telescopic cylinder 206a.

[0044] A first spring 206c is added to the telescopic component 206. Its elasticity can assist the telescopic rod 206b to rise, ensuring the smoothing effect of the scraper 211.

[0045] Specifically, the guide component 207 includes a guide wheel 207a fixedly connected to one side of the bottom of the telescopic rod 206b, and guide frames 207b fixedly connected to both sides of the mold 103, which cooperate with the guide wheel 207a.

[0046] Since the mold 103 is arc-shaped, the guide wheel 207a cooperates with the guide frame 207b to provide guidance for the movement of the scraper 211, so that the scraper 211 moves accurately along the arc-shaped top surface of the mold 103, preventing deviation and ensuring the smoothing accuracy.

[0047] Specifically, the mounting component 208 includes a mounting block 208a fixedly connected to the surface of the telescopic rod 206b. The top of the mounting block 208a has an embedding groove 208b that cooperates with the connecting plate 209. The bottom of the embedding groove 208b is fixedly connected to a locking block 208c, and the bottom of the connecting plate 209 has a locking groove 208d.

[0048] The mounting component 208, through the cooperation of mounting block 208a, embedding groove 208b, locking block 208c and locking groove 208d, enables the quick connection between the connecting plate 209 and the telescopic rod 206b, facilitating the installation and disassembly of the scraper 211 and the vibrator 210, and making it easier for later maintenance and component replacement.

[0049] Specifically, a limiting groove 208e is provided on both sides of the embedded groove 208b. A limiting block 208f is slidably connected to the inner cavity of the limiting groove 208e. A second spring 208g is fixedly connected to the side of the limiting block 208f away from the connecting plate 209. The side of the second spring 208g away from the limiting block 208f is fixedly connected to the inner cavity of the limiting groove 208e.

[0050] After the connecting plate 209 is installed, the limiting block 208f is reset under the action of the second spring 208g, which limits and fixes the connecting plate 209, enhances the connection stability, and prevents the connecting plate 209 from loosening and falling off during vibration.

[0051] Specifically, a connecting rod 208h is fixedly connected to the top of the limiting block 208f. There are two sets of connecting rods 208h, which are staggered. A pressing plate 208i is fixedly connected to the top of the connecting rod 208h.

[0052] The connecting rod 208h and the pressing plate 208i enable convenient operation of the limiting block 208f. When it is necessary to disassemble the connecting plate 209, pressing the pressing plate 208i can easily drive the limiting block 208f into the limiting groove 208e, thereby releasing the fixation of the connecting plate 209. The operation is simple and efficient.

[0053] Specifically, the mounting block 208a has through slots 208j on both sides of its top, which cooperate with the connecting rod 208h.

[0054] The through groove 208j provides a channel for the sliding of the connecting rod 208h, ensuring that the pressing plate 208i can smoothly drive the limit block 208f to move, so that the installation and disassembly of the connecting plate 209 can be carried out smoothly.

[0055] Specifically, the bottom of the limiting block 208f is fixedly connected to the slider 208f-1, and the bottom of the limiting groove 208e is provided with a sliding groove 208f-2, which cooperates with the slider 208f-1.

[0056] The cooperation between slider 208f-1 and slide groove 208f-2 further enhances the stability of the limiting block 208f sliding within the limiting groove 208e, prevents the limiting block 208f from shifting during sliding, and ensures the reliability of the installation and disassembly of the connecting plate 209.

[0057] Specifically, the collecting component 302 includes a collecting tray 302a fixedly connected to the top of the frame 301, a collecting cylinder 302b connected to the bottom of the collecting tray 302a, and a threaded conveyor 302c connected to the bottom of the collecting cylinder 302b.

[0058] The collection tray 302a, collection cylinder 302b and threaded conveyor 302c of the collection component 302 constitute a complete collection and conveying system. The collection tray 302a receives the excess concrete scraped off by the scraper 211. After being collected by the collection cylinder 302b, it is conveyed uniformly by the threaded conveyor 302c, realizing the effective collection and convenient treatment of excess concrete and avoiding concrete spillage and waste.

[0059] Working principle: After concrete is poured into the mold 103, the upright 201 is fixed to the top of the mounting plate 101, and the crossbar 202 connects to the upright 201. The chain drive device drives the moving frame 203 to slide on the crossbar 202, thereby realizing automatic translation and smoothing. The telescopic component 206, composed of the telescopic cylinder 206a and the telescopic rod 206b, works with the first spring 206c to enable the scraper 211 to adaptively adjust its height and maintain appropriate pressure according to the shape changes of the arc-shaped top surface of the mold 103. The guide wheel 207a moves along the guide frame 207b, guiding the scraper 211 along the mold. The top surface of the 103 moves accurately. During installation, the connecting plate 209 is embedded into the embedding groove 208b of the mounting block 208a. During the pushing process, the limiting block 208f is squeezed and compresses the second spring 208g. When the locking block 208c engages with the locking groove 208d, the limiting block 208f resets and fixes the connecting plate 209 under the action of the second spring 208g, thereby fixing the vibrator 210 and the scraper 211. During disassembly, the pressing plate 208i is pressed, and the connecting rod 208h drives the limiting block 208f to slide into the limiting groove 208e, releasing the fixation of the connecting plate 209.

[0060] During the smoothing process, the vibrator 210 drives the scraper 211 to vibrate the concrete at high frequency, making the concrete uniform. The excess concrete scraped off by the scraper 211 falls into the collection tray 302a, and is then transported and collected by the threaded conveyor 302c through the collection cylinder 302b.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
